Certainly, in another embodiment, the power supply assembly 102 and the atomizer 101 may also be integrally arranged, which is not limited in this application.
Referring to FIG. 2 to FIG. 4 , FIG. 2 is a schematic structural diagram of an atomizer according to an embodiment of this application; FIG. 3 is a cross-sectional view along a direction A-A of the atomizer shown in FIG. 2 according to a first embodiment of this application; and FIG. 4 is an exploded view of the atomizer shown in FIG. 2 according to the first embodiment of this application. In this embodiment, an atomizer 101 a is provided. The atomizer 101 a includes a housing 10 a and an atomization core 20.
As shown in FIG. 3 and FIG. 4 , the housing 10 a includes an accommodating cavity. The atomization core 20 is arranged inside the accommodating cavity, and cooperates with a surface of an inner wall of the housing 10 a to form a liquid storage chamber 201 a. The liquid storage chamber 201 a is configured to store an aerosol-generating substrate. In a specific embodiment, the atomization core 20 is configured to heat and atomize, when energized, the aerosol-generating substrate from the liquid storage chamber 201 a, to form an aerosol. Specifically, referring to FIG. 3 , the housing 10 a further includes a mouthpiece 11 and an air outlet channel 12. The mouthpiece 11 may be formed above the atomizer 101 a along the length direction of the atomizer 101 a. The air outlet channel 12 is in communication with the mouthpiece 11 and the atomization core 20. The aerosol obtained after the aerosol-generating substrate is atomized flows out from the mouthpiece 11 through the air outlet channel 12 for the user to inhale. The atomization core 20 may be an atomization core involved in any one of the following embodiments. For the specific structures and functions of the atomization core 20, reference may be made to the following related text descriptions.
Referring to FIG. 3 to FIG. 5 b , FIG. 5 a is a schematic overall structural diagram of an atomization core of the atomizer shown in FIG. 4 except for a first sealing member; and FIG. 5 b is a cross-sectional view along a direction B-B of the atomization core shown in FIG. 5 a . In this embodiment, a first type of atomization core 20 a is provided. The atomization core 20 a includes: a base 21, a seat 22 arranged on the base 21, a liquid guiding member 23, a heating component 24, and an electrode lead 25 a.
As shown in FIG. 5 b , the base 21 includes a receiving groove, and the seat 22 is embedded in the receiving groove of the base 21. In addition, an atomization chamber 220 and a first liquid inlet hole 2213 in communication with the atomization chamber 220 are formed on the seat 22. An aerosol-generating substrate specifically enters the atomization chamber 220 through the first liquid inlet hole 2213. In an implementation, one first liquid inlet hole 2213 is provided on the seat 22, and the first liquid inlet hole 2213 is formed on a side surface of the seat 22, that is, the first liquid inlet hole 2213 is opposite to a side surface of the housing 10 a, to implement one-way liquid inlet from the side surface of the atomization core 20 a, which is used as an example in all the following embodiments. Certainly, a plurality of first liquid inlet holes 2213 may 2213 may alternatively be provided on the seat 22, and the plurality of first liquid inlet holes 2213 may be opposite to a side surface of the housing 10 a. The liquid guiding member 23 is arranged inside the atomization chamber 220, and configured to guide the aerosol-generating substrate that enters the atomization chamber 220 from the first liquid inlet hole 2213. The heating component 24 is arranged on the side surface of the liquid guiding member 23 facing away from the first liquid inlet hole 2213 and configured to atomize, when energized, the aerosol-generating substrate, to form the aerosol for the user to inhale. The electrode lead 25 a includes an abutting portion and a lead portion that are connected to each other. In an implementation, the abutting portion is the extension of the lead portion. The abutting portion of the electrode lead 25 a is electrically connected to the heating component 24 and fixes the heating component 24 to the liquid guiding member 23, to improve the fit between the two to avoid the problem of dry heating of the heating component 24. The lead portion is connected to one end of the abutting portion, configured to connect to the power supply assembly 102.
Since the liquid guiding member 23 is arranged in the whole circumferential direction of the atomization chamber 220, that is, the liquid guiding member 23 is in a closed loop shape, when the size of the liquid guiding member 23 is small, a liquid film is easily formed on the liquid guiding member 23, resulting in the problem of inhaling the leaked liquid. Therefore, the liquid guiding member 23 may be curved, and the radian range of the liquid guiding member 23 may be 20° to 55°. The liquid guiding member 23 may be specifically a curved liquid absorption sponge. The heating component 24 may be a curved metal heating mesh, and the radian of the curved liquid absorption sponge is consistent with that of the curved metal heating mesh, to help the two fit perfectly and reduce the probability of the dry heating problem of the heating component 24.
As shown in FIG. 4 , the seat 22 includes a first seat body 221 and a second seat body 222. The first seat body 221 and the second seat body 222 have a curved structure, and the first seat body 221 and the second seat body 222 are detachably connected and cooperate to form the atomization chamber 220.
As shown in FIG. 6 , FIG. 6 is a schematic structural diagram of a first seat body 221 according to an embodiment of this application. The first seat body 221 includes a first installation portion and a first engagement portion. The first installation portion is embedded in the receiving groove, to be installed and fixed onto the base 21. In addition, the first installation portion is provided with a wire outlet hole 2211 for the electrode lead 25 a to pass through. The first engagement portion and the first installation portion are integrally formed, and a first groove 2212 is provided on the side surface of the first engagement portion facing toward the second seat body 222. The second seat body 222 cooperates with the first groove 2212 of the first seat body 221 to form the atomization chamber 220.
The first groove 2212 may be a curved groove, and the first liquid inlet hole 2213 is specifically provided on the bottom wall of the first groove 2212. In a specific embodiment, as shown in FIG. 7 , FIG. 7 is a schematic structural diagram of the liquid guiding member 23, the heating component 24, and the electrode lead 25 a being arranged inside the first groove 2212 according to an embodiment of this application. The liquid guiding member 23 is arranged in fit with the bottom wall of the first groove 2212 and covers the first liquid inlet hole 2213, to guide the aerosol-generating substrate in the first liquid inlet hole 2213 to the side of the liquid guiding member 23 facing away from the first liquid inlet hole 2213.
In an implementation, the first liquid inlet hole 2213 overlaps with a high-temperature region of the heating component 24. That is, the projection of the high-temperature region of the heating component 24 along the stacking direction of the heating component 24 and the liquid guiding member 23 is at least partially located in the region in which the first liquid inlet hole 2213 is located, to increase the atomization amount.
The high-temperature region of the heating component 24 refers to the middle region of the heating component 24, and the temperature corresponding to the high-temperature region is greater than is equal to 240°. In a specific embodiment, the area of the first liquid inlet hole 2213 is greater than or equal to the area of the high-temperature region of the heating component 24, and the projection of the high-temperature region of the heating component 24 along the stacking direction of the heating component 24 and the liquid guiding member 23 is completely located in the region in which the first liquid inlet hole 2213 is located. In addition, it has been proved by experiments that the first liquid inlet hole 2213 is a place at which the aerosol-generating substrate is densest. Therefore, maintaining the high temperature at the position of the first liquid inlet hole 2213 is conducive to the atomization of the aerosol-generating substrate, thereby sufficiently generating the aerosol.
Further, referring to FIG. 6 or FIG. 7 , the first engagement portion is further provided with an air outlet opening 2214. The air outlet opening 2214 is in communication with the first groove 2212 and is specifically located on a sidewall of the first groove 2212. In a specific embodiment, the aerosol formed through atomization inside the atomization chamber 220 specifically flows out through the air outlet opening 2214. The air outlet opening 2214 may be arranged at a position above the first groove 2212 along the direction of the air outlet path C of the atomization core 22 a.
Further, as shown in FIG. 6 or FIG. 7 , a plurality of first liquid absorption slots 2215 are provided on the side surface of the first installation portion facing toward the second seat body 222. The plurality of first liquid absorption slots 2215 are in communication with the bottom of the atomization chamber 220, and the plurality of first liquid absorption slots 2215 may be specifically located on the side of the first groove 2212 facing away from the air outlet opening 2214, to guide, through the capillary force, the aerosol-generating substrate flowing out from the bottom of the atomization chamber 220 into the first liquid absorption slots 2215, to avoid the leakage problem. The first liquid absorption slot 2215 mayextend in the direction facing away from the air outlet opening 2214, and the plurality of first liquid absorption slots 2215 may be spaced apart along the circumferential direction of the first seat body 221. It should be noted that in the embodiments involved in this application, the bottom of the atomization chamber 220 specifically refers the lower part of the atomization chamber 220 according to the orientation shown in FIG. 3 . The sidewall of the atomization chamber 220 specifically refers to the left and right sides of the atomization chamber 220 according to the orientation shown in FIG. 3 .
Referring to FIG. 8 , FIG. 8 is a schematic structural diagram of the second seat body 222 under a first view according to the first embodiment of this application.

Further, the first side edge and the second side edge of the heating component 24 are arranged correspondingly to a first side edge and a second side edge of the liquid guiding member, to prevent, while fixing the heating component 24 to the liquid guiding member 23 at the first sidewall 2221 and the second sidewall 2222, the two sides of the liquid guiding member 23 from bulging.
Further, the vertical distance between the first sidewall 2221 and/or second sidewall 2222 and the bottom wall of the first groove 2212 is less than the thickness of the heating component 24, to ensure that the heating component 24 perfectly fits the liquid guiding member 23.

Referring to FIG. 7 and FIG. 10 , FIG. 10 is a schematic structural diagram of the heating component 24 according to an embodiment of this application. The heating component 24 includes a heating element 241 and a first pin 242 and a second pin 243 that are connected to the heating element 241. The heating element 241 is configured to heat and atomize, when energized, the aerosol-generating substrate. The first pin 242 and the second pin 243 are located on two sides of the heating element 241 respectively, and form a third side edge and a fourth side edge of the heating component 24. The third side edge and the fourth side edge of the heating component 24 are respectively arranged adjacent to the first side edge and the second side edge of the heating component 24. The electrode lead 25 a specifically includes a positive electrode lead 251 a and a negative electrode lead 252 a. An abutting portion 2511 a of the positive electrode lead is electrically connected to and abuts against the first pin 242, to fix the first pin 242 of the heating component 24 to the liquid guiding member 23, and an abutting portion 2521 a of the negative electrode lead is electrically connected to and abut against the second pin 243, to fix the second pin 243 of the heating component 24 to the liquid guiding member 23, to prevent the heating component 24 from being separated from the liquid guiding member 23 and causing the problem of dry heating of the heating component 24.
In an embodiment, as shown in FIG. 7 , after the heating component 24 is installed on the first groove 2212, the first pin 242 is located on the side of the heating element 241 close to the air outlet opening 2214 along the direction of the air outlet path C of the atomization core 20 a, and the second pin 243 is located on the side of the heating element 241 away from the air outlet opening 2214 along the direction of the air outlet path C of the atomization core 20 a. In this case, the abutting portion 2511 a of the positive electrode lead abutting against the first pin 242 is located on the side of the heating element 241 close to the air outlet opening 2214 along the direction of the air outlet path C of the atomization core 20 a, and the abutting portion 2521 a of the negative electrode lead abutting against the second pin 243 is located on the side of the heating element 241 away from the air outlet opening 2214 along the direction of the air outlet path C of the atomization core 20 a, which is used as an example in all the following embodiments. In an alternative embodiment, the first pin 242 is located on the side of the heating element 241 away from the air outlet opening 2214 along the direction of the air outlet path C of the atomization core 20 a, and the second pin 243 is located on the side of the heating element 241 close to the air outlet opening 2214 along the direction of the air outlet path C of the atomization core 20 a. In this case, the abutting portion 2511 a of the positive electrode lead abutting against the first pin 242 is located on the side of the heating element 241 away from the air outlet opening 2214 along the direction of the air outlet path C of the atomization core 20 a, and the abutting portion 2521 a of the negative electrode lead abutting against the second pin 243 is located on the side of the heating element 241 close to the air outlet opening 2214 along the direction of the air outlet path C of the atomization core 20 a.
Fixing the heating component 24 to the liquid guiding member 23 through the electrode lead 25 a can effectively improve the fit between the heating component 24 and the liquid guiding member 23, to avoid the probability that dry heating of the heating component 24 produces an inhaled burnt smell. Moreover, compared with the manner of fixing the first pin 242 and the second pin 243 of the heating component 24 using another fixing member, the electrode lead 25 a has less impact on suction resistance of airflows. It may be understood that, the first side edge and the second side edge of the heating component 24 mentioned above specifically refer to two side edges that are of the heating element 241 and that are different from the two side edges connected to the first pin 242 and the second pin 243.
The abutting portion 2511 a of the positive electrode lead and the abutting portion 2521 a of the negative electrode lead extend along the third side edge and the fourth side edge of the heating component 24 respectively, and extend in opposite directions, to ensure as much as possible that positions on the heating component 24 are evenly stressed. Further, the abutting portion 2511 a of the positive electrode lead and the abutting portion 2521 a of the negative electrode lead are parallel to each other.
The heating element 241, the first pin 242, and the second pin 243 are all curved along the direction perpendicular to the air outlet path C of the atomization core 20 a, to come into better contact with the liquid guiding member 23. In this embodiment, still referring to FIG. 7 , the abutting portion 2511 a of the positive electrode lead is bent into a first curved portion, and the first curved portion extends along the first pin 242 and abuts against the first pin 242. In this way, the contact area between the positive electrode lead 251 a and the first pin 242 can be effectively increased, thereby enabling the first pin 242 of the heating component 24 to come into better contact with the liquid guiding member 23. Specifically, the radian of the first curved portion matches the radian of the first pin 242, to ensure that the two can fit perfectly.
The abutting portion 2521 a of the negative electrode lead is bent into a second curved portion, and the second curved portion extends along the second pin 243 and abuts against the second pin 243. In this way, the contact area between the negative electrode lead 252 a and the second pin 243 can be effectively increased, thereby enabling the second pin 243 of the heating component 24 to come into better contact with the liquid guiding member 23. Specifically, the radian of the second curved portion matches the radian of the second pin 243, to ensure that the two can fit perfectly.
A lead portion 2512 a of the positive electrode lead is bent relative to the first curved portion and extend toward the direction of the atomization chamber 220 facing away from the air outlet opening 2214. A lead portion 2522 a of the negative electrode lead is bent relative to the second curved portion and extend toward the direction of the atomization chamber 220 facing away from the air outlet opening 2214. In addition, the bending place of the positive electrode lead 251 a and the bending place of the negative electrode lead 252 a are located at two opposite corners of the heating component 24. That is, the joint between the abutting portion 2511 a of the positive electrode lead and the lead portion 2512 a of the positive electrode lead and the joint between the abutting portion 2521 a of the negative electrode lead and the lead portion 2522 a of the negative electrode lead are located at two opposite corners of the heating component 24, to further strengthen the fixation effect of the electrode lead 25 a on the heating component 24.
In a specific embodiment, the lead portion 2512 a of the positive electrode lead is located on the side of the second side edge of the heating component 24 facing away from the first side edge, and the lead portion 2522 a of the negative electrode lead is located on the side of the first side edge of the heating component 24 facing away from the second side edge. In an alternative embodiment, the lead portion 2512 a of the positive electrode lead may alternatively be located on the side of the first side edge of the heating component 24 facing away from the second side edge, and the lead portion 2522 a of the negative electrode lead may alternatively be located on the side of the second side edge of the heating component 24 facing away from the first side edge.
Referring to FIG. 11 to FIG. 14 , FIG. 11 is a schematic diagram of a stress-bearing part of the heating component 24 according to an embodiment of this application; FIG. 12 is a diagram of deformation of the heating component 24 corresponding to FIG. 11 after being stressed; FIG. 13 is a schematic diagram of a stress-bearing part of the heating component 24 according to another embodiment of this application; and FIG. 14 is a diagram of deformation of the heating component 24 corresponding to FIG. 13 after being stressed. A position C1/C2, a position D1/D2, a position E2, and a position F2 in the figures refer to stress-bearing positions of the second pin 243, the first pin 242, the first side edge, and the second side edge respectively. Upon comparison between FIG. 12 and FIG. 14 , it can be learned that an evenly distributed normal stress F′ is applied to a stress-bearing surface. For example, a resultant force to which the stress-bearing surface is subjected is 1 N, the maximum center deformation amount of the heating component 24 corresponding to FIG. 11 is 2.83e-7, and the maximum center deformation amount of the heating component 24 corresponding to FIG. 13 is 3.3981e-8. In view of the above, the center deformation amount of the heating component 24 corresponding to FIG. 13 is one order of magnitude smaller than the center deformation amount of the heating component 24 corresponding to FIG. 11 . Therefore, the positive electrode lead 251 a and the negative electrode lead 252 a are used to fix the first pin 242 and the second pin 243 of the heating component 24 respectively, and the second seat body 222 is used to fix the first side edge and the second side edge of the second pin 243 that is of the heating component 24 and that is different from the first pin 242, to enable the heating component 24 better fit the liquid guiding member 23.
For the atomization core 20 a provided in this embodiment, the seat 22 and the liquid guiding member 23 are arranged such that the liquid guiding member 23 is arranged inside the atomization chamber 220 of the seat 22, to guide the aerosol-generating substrate through the liquid guiding member 23. In addition, the heating component 24 is arranged such that the heating component 24 is arranged on the liquid guiding member 23, to atomize the aerosol-generating substrate when the heating component 24 is energized. Moreover, the electrode lead 25 a is arranged such that the electrode lead 25 a is electrically connected to the heating component 24 and fixes the heating component 24 to the liquid guiding member 23. Fixing the heating component 24 to the liquid guiding member 23 through the electrode lead 25 a can effectively improve the fit between the heating component 24 and the liquid guiding member 23, to avoid the probability that dry heating of the heating component 24 produces an inhaled burnt smell. Moreover, compared with another fixing member, the electrode lead 25 a has less impact on suction resistance of airflows. In addition, the first sidewall 2221 and the second sidewall 2222 of the second seat body 222 are pressed against two side edges of the heating component 24, and the first sidewall 2221 and the second sidewall 2222 are arranged on two sides of the air outlet opening 2214 along the direction perpendicular to the air outlet path C of the atomization core 20 a, which not only can better fix the heating component 24 to the liquid guiding member 23, but also can prevent the first sidewall 2221 and the second sidewall 2222 from blocking airflows.
To improve the sealing effect of the atomization chamber 220, in an embodiment, referring to FIG. 4 and FIG. 15 a to FIG. 15 c , FIG. 15 a is a schematic overall structural diagram of an atomization core of the atomizer shown in FIG. 4 . FIG. 15 b is a perspective view of an atomization core of the atomizer shown in FIG. 4 ; and FIG. 15 c is a cross-sectional view along a direction B-B of the atomization core shown in FIG. 15 b .

In addition, the first sealing member 26 a is further provided with a second liquid inlet hole 261 at a position corresponding to the first liquid inlet hole 2213. The aerosol-generating substrate inside the liquid storage chamber 201 a specifically enters the atomization chamber 220 through the second liquid inlet hole 261 and the first liquid inlet hole 2213, and then, is guided using the liquid guiding member 23.
Specifically, as shown in FIG. 15 a , the first sealing member 26 a is provided with a ventilation hole 262 at a position corresponding to a port of a straight liquid ventilation channel, and the ventilation hole 262 is arranged corresponding to the liquid storage chamber 201 a. The liquid storage chamber 201 a is in communication with the atmosphere outside through the ventilation hole 262 and the straight liquid ventilation channel, to implement the ventilation function of the liquid storage chamber 201 a and control the air pressure inside the liquid storage chamber 201 a.
In a specific embodiment, referring to FIG. 4 , the atomizer 101 a further includes a liquid injection port steel ring 27, a mouthpiece cover 28, a second sealing member 29, a third sealing member 30, two ejector pins 31, and a magnet 32. The liquid injection port steel ring 27 is sleeved over a liquid injection port of the first sealing member 26 a, and the second sealing member 29 is sleeved over the liquid injection port steel ring 27. The mouthpiece cover 28 covers the end of the first sealing member 26 a facing away from the base 21, and forms an inhalation opening in communication with the air outlet opening 2214. The aerosol formed through atomization inside the atomization chamber 220 is sucked to the inhalation opening through the air outlet opening 2214, to enter the mouth of the user. The two ejector pins 31 are embedded in the base 21 and connected to the positive electrode lead 251 a and the negative electrode lead 252 a respectively, for the two ejector pins 31 to electrically connect the positive electrode lead 251 a and the negative electrode lead 252 a to the power supply assembly 102 when being in electrical contact with the positive electrode and the negative electrode of the power supply assembly 102. The magnet 32 is embedded in the base 21, and is located on the side surface of the base 21 facing away from the seat 22 and configured to be installed and fixed onto a host.
The following describes the specific assembly process of the atomizer 101 a provided by this embodiment: First, the heating component 24 that is initially flat during delivery from the factory is placed in a forming jig for the heating component 24, and an indenter is pressed on the heating component 24, to deform the heating component 24 into a curved shape.

Then, the liquid guiding member 23 is placed into the first groove 2212, and further, the heating component 24 is placed on the liquid guiding member 23. Afterward, the second seat body 222 and the first seat body 221 are fixed and assembled using the buckles and the positioning posts 2216. The first sealing member 26 a is sleeved over the outer sides of the foregoing assembled assembly.

Finally, the housing 10 a, the liquid injection port steel ring 27, the mouthpiece cover 28, the second sealing member 29, and the third sealing member 30 are assembled with the foregoing assembly, to complete the assembly. The first sealing member 26 a, the second sealing member 29, and the third sealing member 30 may be elastic silica gel parts such as silica gel or rubber.
Compared with the first type of atomization core 20 a, the atomization core 20 b provided by this embodiment can better seal the atomization chamber 220 by further arranging the first sealing member 26 a, to avoid the problem that leakage of the atomization chamber 220 causes damage to another electronic device. In addition, the atomizer 101 a corresponding to the second type of atomization core 20 b can simplify the assembly process and improve the assembly consistency of the liquid guiding member 23 without changing the materials of the liquid guiding member 23 and the heating component 24.
Referring to FIG. 16 to FIG. 17 b , FIG. 16 is an exploded view of the atomizer shown in FIG. 2 according to a second embodiment of this application; FIG. 17 a is a schematic exploded view of an atomization core 20 c in the atomizer 101 b shown in FIG. 16 according to an embodiment of this application; and FIG. 17 b is a schematic exploded view of an atomization core 20 c in the atomizer 101 b shown in FIG. 16 according to another embodiment of this application. In this embodiment, a third type of atomization core 20 c is provided. Different from the foregoing two types of atomization cores 20 a/20 b, the electrode lead 25 b of the third type of atomization core 20 c is further fixed to the seat 22 to strengthen the supporting effect of the electrode lead 25 b on the heating component 24 and prevent the heating component 24 from bulging and deforming. For the specific structure of the atomizer 101 b corresponding to this embodiment, reference may be made to FIG. 16 .
Specifically, referring to FIG. 17 a to FIG. 18 , FIG. 18 is a schematic structural diagram of the liquid guiding member 23, the heating component 24, and the electrode lead 25 b being arranged inside the first groove 2212 according to another embodiment of this application. The electrode lead 25 b further includes an extending portion connected to the abutting portion. The extending portion may be connected to the end of the abutting portion facing away from the lead portion, is linear, and is fixedly connected to the seat 22. Specifically, an extending portion 253 of the positive electrode lead is connected to the end of the abutting portion 2511 b of the positive electrode lead facing away from the lead portion 2512 b of the positive electrode lead, and an extending portion 254 of the negative electrode lead is connected to the end of the abutting portion 2521 b of the negative electrode lead facing away from the lead portion 2522 b of the negative electrode lead.
In an embodiment, as shown in FIG. 18 , the seat 22 is provided with two fixing holes 2218. The extending portion 253 of the positive electrode lead and the extending portion 254 of the negative electrode lead respectively penetrate through the two fixing holes 2218, to be fixed to the seat 22. In a specific embodiment, the extending portion is the extension of abutting portion. Certainly, in another embodiment, the extending portion may also be connected to another position of the abutting portion, for example, the middle position of the abutting portion, and the extending portion may also be fixed to the seat 22 by welding, buckling, or the like, which is not limited in this application.
Further, referring to FIG. 18 , different from the foregoing two types of atomization cores 20 a/20 b, in this embodiment, the abutting portion 2511 b of the positive electrode lead and the abutting portion 2521 b of the negative electrode lead are located on two sides of the air outlet opening 2214 along a direction perpendicular to the air outlet path C of the atomization core 20 c, and the two fixing holes 2218 are specifically provided on the first seat body 221, and are located on the two sides of the air outlet opening 2214 along a direction perpendicular to the air outlet path C of the atomization core 20 c.
In addition, as shown in FIG. 17 b , the heating component 24 is bent into a curved shape along the direction of the air outlet path C of the atomization core 20 c. That is, the heating element 241 of the heating component 24, the first pin 242, and the second pin 243 are all bent into a curved shape along the direction of the air outlet path C of the atomization core 20 c. The abutting portion 2511 b of the positive electrode lead is bent to form a first curved portion, and the first curved portion extends along and abuts against the first pin 242 of the heating component 24. The abutting portion 2521 b of the negative electrode lead is bent to form a second curved portion, and the second curved portion extends along and abuts against the second pin 243 of the heating component 24. In this way, the fit between the first pin 242 and second pin 243 of the heating component 24 and the liquid guiding member 23 is enhanced through the arc-shaped stress, and prevent the heating component 24 from bulging and deforming.
After the assembly of the liquid guiding member 23 and the heating component 24 is completed, because the liquid guiding member 23 applies a stress facing toward the heating component 24 to the heating component 24, the heating component 24 is forced to bulge and deform. In the atomization core 20 c provided by this embodiment, not only the curved heating component 24 itself can provide a bending moment, but also the interaction between the curved abutting portion of the electrode lead 25 b abutting against the first pin 242 and second pin 243 of the heating component 24, as well as the extending portion of the electrode lead 25 b, and the seat 22 can further provide a specific reverse moment to the heating component 24, thereby further preventing the heating component 24 from bulging and deforming.
Compared with the foregoing two types of atomization cores 20 a/20 b, the third type of atomization core 20 c provided by this embodiment can effectively improve the bending moment of the heating component 24 by further fixing the electrode lead 25 b to the seat 22. In addition, the abutting portion 2511 b of the positive electrode lead and the abutting portion 2521 b of the negative electrode lead are further arranged on the two sides of the air outlet opening 2214 respectively along the direction perpendicular to the air outlet path C of the atomization core 20 c, to further prevent the electrode lead 25 b from blocking airflows.
Referring to FIG. 19 , FIG. 19 is a top view of an atomization core according to an embodiment of this application. To prevent the heating component 24 from bulging and deforming at another position other than edge positions, in an embodiment, a fourth type of atomization core 20 d is provided. Different from the foregoing three types of atomization cores 20 a/20 b/20 c, the fourth type of atomization core 20 d further includes a fixing portion 33. The fixing portion 33 is arranged at a position opposite to another position of the heating component 24 other than edge positions, to prevent the heating component 24 from bulging and deforming. In some implementations, the fixing portion 33 is not in contact with the heating component 24, and there is a specific gap, to reduce the impact of the temperature of the heating component 24 on the fixing portion 33. In some other implementations, the fixing portion 33 is in contact with the heating component 24 to support and limit the heating component 24, to prevent the heating component 24 from bulging and deforming.
The radian of the side surface of the fixing portion 33 close to the heating component 24 matches the radian of the heating component 24 at a corresponding position, thereby further preventing the heating component 24 from bulging and deforming.
In an embodiment, the fixing portion 33 is provided at the middle part of the second seat body 222. The middle part of the second seat body 222 refers to a position of the second seat body 222 different from its ends (or edges). In this way, after the two side edges of the heating component 24 and the two side edges of the liquid guiding member 23 are clamped by the seat 22 respectively, the middle part of the heating component 24 can be limited by the fixing portion 33, to prevent the middle part of the heating component 24 other than the two side edges from bulging and causing the problem of deformation.
The fixing portion 33 is specifically formed on the side surface of the second seat body 222 facing toward the first seat body 221, and is located between the first sidewall 2221 and the second sidewall 2222. In this embodiment, the fixing portion 33 may be integrally formed with the second seat body 222, for the specific arrangements between the second seat body 222, the heating component 24, and the electrode lead 25 b, reference may be made to FIG. 17 a to FIG. 18 and the corresponding text descriptions, and this is used as an example in the following embodiments. Certainly, the fixing portion 33 may alternatively be formed on the first seat body 221 and bent toward the heating component 24 to abut against the heating component 24. The electrode lead 25 b and/or the first sidewall 2221 and second sidewall 2222 of the second seat body 222 may also be arranged oppositely along the direction of the air outlet path C of the atomization core.
In one embodiment, referring to FIG. 20 , FIG. 20 is a schematic structural diagram of the second seat body 222 of the fourth type of atomization core 20 d according to the first embodiment of this application. The fixing portion 33 includes at least one first extending wall 33 a. The at least one first extending wall 33 a is located between the first sidewall 2221 and the second sidewall 2222, and is spaced apart between the first sidewall 2221 and the second sidewall 2222. Each first extending wall 33 a extends in parallel to the direction of the air outlet path C of the atomization core 20 d. Certainly, the first extending wall 33 a may alternatively be arranged at a specific angle to the direction of the air outlet path C of the atomization core 20 d. In this case, a through hole may be provided on the first extending wall 33 a along the direction of the air outlet path C of the atomization core 20 d, to allow airflows to pass through and avoid blocking the airflows.
In an embodiment, there is one first extending wall 33 a, and the first extending wall 33 a is located at the middle position between the first sidewall 2221 and the second sidewall 2222. Specifically, the first extending wall 33 a may be arranged in parallel to the first sidewall 2221 and the second sidewall 2222, and cooperates with the first sidewall 2221 and the second sidewall 2222 to form two air outlet channels in communication with the air outlet opening 2214. It may be understood that, in this embodiment, the first sidewall 2221, the first extending wall 33 a, and the second sidewall 2222 are distributed in a “ ” shape. In some implementations, the first extending wall 33 a is not in contact with the heating component 24, and there is a specific gap, to reduce the impact of the temperature of the heating component 24 on the first extending wall 33 a.
In another embodiment, referring to FIG. 21 , FIG. 21 is a schematic structural diagram of the second seat body 222 of the fourth type of atomization core 20 d according to the second embodiment of this application. The fixing portion 33 further includes a second extending wall 33 b. The second extending wall 33 b and the first extending wall 33 a are arranged in an intersecting manner. The second extending wall 33 b is provided with at least one first through hole 331 b along the air outlet path C of the atomization core 20 d for airflows to pass through, thereby avoiding blocking the airflows. Specifically, the second extending wall 33 b and the first extending wall 33 a are distributed in a “cross” shape. At least one first through hole 331 b is evenly distributed on two sides of the first extending wall 33 a.
Specifically, the second extending wall 33 b is provided with two first through holes 331 b along the air outlet path C of the atomization core 20 d, and the two first through holes 331 b are respectively located on two sides of the first extending wall 33 a. The radians of the side surfaces of the first extending wall 33 a and/or the second extending wall 33 b close to the heating component 24 match the radian of the heating component 24, thereby further preventing the heating component 24 from bulging and deforming. In some implementations, neither of the first extending wall 33 a and the second extending wall 33 b is in contact with the heating component 24, and there are specific gaps, to reduce the impact of the temperature of the heating component 24 on the first extending wall 33 a and the second extending wall 33 b.
In still another embodiment, referring to FIG. 22 , FIG. 22 is a schematic structural diagram of the second seat body 222 of the fourth type of atomization core 20 d according to a third embodiment of this application. The fixing portion 33 includes a plurality of third extending walls 33 c. The plurality of third extending walls 33 c are spaced apart along the direction of the air outlet path C of the atomization core 20 d. In addition, each third extending wall 33 c is provided with at least one second through hole 331 c for airflows to pass through, thereby avoiding blocking the airflows. Specifically, the plurality of third extending walls 33 c are parallel to each other.
Specifically, as shown in FIG. 22 , each third extending wall 33 c extends along the direction perpendicular to the air outlet path C of the atomization core 20 d, and abuts against the first sidewall 2221 and the second sidewall 2222 respectively. In a specific embodiment, there may be three third extending walls 33 c, and the three third extending walls 33 c are distributed in a “ ” shape. Certainly, each third extending wall 33 c may alternatively be arrange obliquely at an angle between the first sidewall 2221 and the second sidewall 2222, and the angle may be specifically 30 to 60 degrees.
The radian of the side surface of the third extending wall 33 c close to the heating component 24 matches the radian of the heating component 24, thereby further preventing the heating component 24 from bulging and deforming. In some implementations, the third extending wall 33 c is not in contact with the heating component 24, and there is a specific gap, to reduce the impact of the temperature of the heating component 24 on the third extending wall 33 c.
In another embodiment, referring to FIG. 23 , FIG. 23 is a schematic structural diagram of the second seat body 222 of the fourth type of atomization core 20 d according to a fourth embodiment of this application. The fixing portion 33 includes a plurality of bumps 33 d, and the plurality of bumps 33 d are spaced apart and arranged opposite to the heating component 24 respectively. Specifically, the bump 33 d may be a cylinder. The plurality of bumps 33 d may be evenly distributed between the first sidewall 2221 and the second sidewall 2222 to correspond to different positions of the heating component 24, thereby preventing the problem of local bulging of the heating component 24. It should be noted that the extending wall is strip-shaped, and the bump 33 d is dot-shaped or column-shaped. In some implementations, the bump 33 d is not in contact with the heating component 24, and there is a specific gap, to reduce the impact of the temperature of the heating component 24 on the bump 33 d. Certainly, the bump 33 d may also abut against the heating component 34.
Compared with the foregoing three types of atomization cores 20 a/20 b/20 c, by further arranging the fixing portion 33 and providing through hole on the fixing portion 33 arranged along the direction perpendicular to the air outlet path C of the atomization core 20 d, the fourth type of atomization core 20 d provided by this embodiment not only can effectively prevent the heating component 24 from bulging and deforming, but also can effectively avoid blocking airflows.
A plane perpendicular to the outflow direction of the mouthpiece 11 (that is, the direction of the air outlet path C of the atomization core 20 d) is used as a reference plane in the following embodiments, and the outflow direction of the mouthpiece 11 is the forward direction. As shown in FIG. 24 , FIG. 24 is a schematic structural diagram of an atomization core according to an embodiment of this application being arranged obliquely.
Because a liquid inlet hole 34 of the atomization core is generally located on one side of the atomization core, and there is no liquid inlet hole 34 on an other side of the atomization core, when the atomization core is along the inclination direction shown in FIG. 24 , if there is a small amount of less aerosol-generating substrate in the liquid storage chamber 201 a corresponding to the atomization core, there may be a problem of insufficient liquid supply inside the atomization chamber 220 or dry heating of the heating component 24, and the part of aerosol-generating substrate cannot be fully utilized, resulting in waste.
Therefore, referring to FIG. 25 a to FIG. 26 , FIG. 25 a is an exploded view of the atomizer shown in FIG. 2 according to the third embodiment of this application; FIG. 25 b is a cross-sectional view along a direction B-B of an atomizer 101 c corresponding to FIG. 25 a ; and FIG. 26 is a schematic overall structural diagram of an atomization core 20 e of the atomizer 101 c shown in FIG. 25 b . In an embodiment, another atomizer 101 c is provided. The atomizer 101 c differs from the atomizer 101 a/101 b corresponding to the atomization core 20 a/20 b/20 c/20 d involved in any one of the foregoing embodiments in that: The bottom surface D of the liquid storage chamber 201 a is constructed such that the aerosol-generating substrate can enter the liquid inlet hole 34 when the atomizer 101 c is tilted at any angle.
Specifically, the atomizer 101 c includes a housing 10 a and an atomization core 20 e. The atomization core 20 e is arranged inside the housing 10 a, and cooperates with the housing 10 a to form a liquid storage chamber 201 a. The liquid storage chamber 201 a is configured to store an aerosol-generating substrate. The atomization core 20 e includes an atomization chamber 220 and a liquid inlet hole 34 in communication with the atomization chamber 220. The liquid inlet hole 34 is opposite to a side surface of the housing 10 a and is exposed inside the liquid storage chamber 201 a. The aerosol-generating substrate enters the atomization chamber 220 through the liquid inlet hole 34, to implement one-side liquid inlet of the atomization core 20 e. It should be noted that the liquid inlet hole 34 refers to a port making the liquid storage chamber 201 a in communication with the atomization chamber 220. The liquid inlet hole 34 involved in this embodiment may be the foregoing first liquid inlet hole 2213. When the atomization core 20 e is sheathed with a first sealing member 26 b, if a second liquid inlet hole 261 is provided on the first sealing member 26 b, the liquid inlet hole 34 may be the second liquid inlet hole 261, or the first liquid inlet hole 2213 and the second liquid inlet hole 261 form a through hole.
In an embodiment, the distance between at least a part of the bottom surface D of the liquid storage chamber 201 a and the mouthpiece 11 is less than the maximum distance between the liquid inlet hole 34 and the mouthpiece 11. The vertical distance between the lowest position F of the liquid inlet hole 34 and mouthpiece 11 is the maximum distance between the liquid inlet hole 34 and the mouthpiece 11. In this embodiment, it may be understood that, at least a part of the bottom surface D of the liquid storage chamber 201 a is higher than the lowest position F of the liquid inlet hole 34. In this way, the aerosol-generating substrate inside the liquid storage chamber 201 a can be forced to have a tendency to flow toward a position at which the lowest position F of the liquid inlet hole 34 is located. Therefore, when there is a small amount of less aerosol-generating substrate in the liquid storage chamber 201 a, the aerosol-generating substrate is enabled to converge as much as possible toward the position at which the lowest position F of the liquid inlet hole 34 is located, to enter the atomization chamber 220 for atomization, thereby not only fully atomizing the aerosol-generating substrate inside the liquid storage chamber 201 a and reducing the residue of the aerosol-generating substrate inside the liquid storage chamber 201 a, to improve the product utilization, but also supplying the atomization chamber 220 with the sufficient aerosol-generating substrate and reducing the risk of dry heating of the heating component 24, to improve the product safety.
In a specific embodiment, the side surface of the atomization core 20 e facing toward the mouthpiece 11 forms the bottom surface D of the liquid storage chamber 201 a. As shown in FIG. 26 , the atomization core 20 e includes a sleeve portion 200 a and an atomization portion 200 b. The sleeve portion 200 a is configured to be sleeved over the housing 10 a, and the sleeve portion 200 a includes a first surface. The first surface forms the bottom surface D of the liquid storage chamber 201 a. The atomization portion 200 b is arranged on the first surface of the sleeve portion 200 a. The atomization portion 200 b includes a first side surface G and a second side surface H that are opposite to each other, and an atomization chamber 220 is provided inside the atomization portion 200 b. In a specific embodiment, the liquid inlet hole 34 is specifically formed on a first side surface G of the atomization portion 200 b. Certainly, the bottom surface D of the liquid storage chamber 201 a can also be formed by the housing 10 a, which is not limited in this application.
In an implementation, the other specific structures and functions of the atomization core 20 e are the same as or similar to the specific structures and functions of the first type of atomization core 20 a. In addition, the same or similar technical effects may be achieved. For details, reference may be made to the foregoing related descriptions. In this embodiment, the base 21 forms the sleeve portion 200 a of the atomization core 20 e, the seat 22 forms the atomization portion 200 b of the atomization core 20 e, and the housing 10 a is sleeved over the base 21 and cooperates with the outer wall surface of the seat 22 to form the liquid storage chamber 201 a.
In an implementation, the specific structures and functions of the atomization core 20 e are the same as or similar to the specific structures and functions of the second type of atomization core 20 b. In addition, the same or similar technical effects may be achieved. For details, reference may be made to the foregoing related descriptions. In this embodiment, the first sealing member 26 b cooperates with the housing 10 a to form the liquid storage chamber 201 a, and the first sealing member 26 b forms the outer surface of the atomization core 20 e. It may be understood that, in this embodiment, the first sealing member 26 b forms the bottom surface D of the liquid storage chamber 201 a, which is used as an example in all of the following embodiments.
In an embodiment, as shown in FIG. 26 , the bottom surface D of the liquid storage chamber 201 a is an inclined surface relative to the reference plane, and the lowest position of the inclined surface is close to the liquid inlet hole 34. That is, the lowest position of the inclined surface is located on the side of the atomization core 20 e on which the liquid inlet hole 34 is provided, to help the aerosol-generating substrate enter the liquid inlet hole 34 after converging. When the first sealing member 26 b forms the bottom surface D of the liquid storage chamber 201 a, the liquid inlet hole 34 is located on the first side surface G of the first sealing member 26 b. In addition, in an embodiment, the distance between the lowest position F of the inclined surface and the mouthpiece 11 is the same as the distance between the lowest position F of the liquid inlet hole 34 and the mouthpiece 11, to enable the aerosol-generating substrate to directly enter the liquid inlet hole 34 as much as possible.
Specifically, the angle between the inclination surface and the forward direction is greater than 0 degrees and less than 90 degrees. In a specific embodiment, the angle between the inclined surface and the forward direction may be 30 to 60 degrees. Therefore, when the user inhales, and the atomizer 101 c is obliquely arranged, the aerosol-generating substrate can also enter the liquid inlet hole 34. Further, referring to FIG. 26 , in this embodiment, the atomization core 20 e differs from the foregoing atomization core 20 a/20 b/20 c/20 d in that: The vertical distance between the ventilation hole 262 and the mouthpiece 11 is less than the minimum distance between the liquid inlet hole 34 and the mouthpiece 11, that is, the position of the ventilation hole 262 is higher than the position of the liquid inlet hole 34. The ventilation hole 262 is correspondingly arranged at a higher position of the bottom surface D of liquid storage chamber 201 a, to avoid, when there is a small amount of less aerosol-generating substrate the problem, that the aerosol-generating substrate blocks the ventilation hole 262, thereby improving the ventilation performance and facilitating the liquid discharge.
By making the bottom surface D of the liquid storage chamber 201 a be an inclined surface relative to the reference plane and the lowest position of the inclined surface close to the liquid inlet hole 34, the atomizer 101 c provided by this embodiment can help the aerosol-generating substrate to converge toward the liquid inlet hole 34, to help the aerosol-generating substrate to enter the liquid inlet hole 34 after the converging, thereby improving the utilization of the aerosol-generating substrate and reducing the occurrence of the problem of dry heating of the heating components 24.
In another embodiment, the distance between at least a part of the bottom surface D of the liquid storage chamber 201 a and the mouthpiece 11 is greater than the minimum distance between the liquid inlet hole 34 and the mouthpiece 11. The vertical distance between the highest position F of the liquid inlet hole 34 and mouthpiece 11 is the minimum distance between the liquid inlet hole 34 and the mouthpiece 11. In this embodiment, it may be understood that the highest position of the liquid inlet hole 34 is higher than at least a part of the bottom surface D of the liquid storage chamber 201 a.
Referring to FIG. 27 a and FIG. 27 b , FIG. 27 a is a cross-sectional view along a direction B-B of an atomizer 101 d shown in FIG. 2 according to the second embodiment of this application; and FIG. 27 b is a schematic overall structural diagram of an atomization core 20 f of the atomizer 101 d shown in FIG. 27 a . The bottom surface D of the liquid storage chamber 201 a is entirely higher than the lowest position F of the liquid inlet hole 34 and lower than the highest position of the liquid inlet hole 35. Further, a groove 35 is formed at a position corresponding to the liquid inlet hole 34 and on the bottom surface D of the liquid storage chamber 201 a, and the lowest position F of the liquid inlet hole 34 is located in the groove 35. In this way, when there is a small amount of less aerosol-generating substrate, the aerosol-generating substrate converges in the groove 35, which can increase the relative height of the aerosol-generating substrate compared with the solution that the aerosol-generating substrate is dispersed throughout the bottom surface D of the liquid storage chamber 201 a. Therefore, a small amount of aerosol-generating substrate can also flow into the atomization chamber 220 through the liquid inlet hole 34, thereby improving the utilization rate of the aerosol-generating substrate and preventing the problem of dry heating of the heating components 24. The atomizer 101 d corresponding to this embodiment may be an open atomizer. That is, the user can re-inject the aerosol-generating substrate after using up the aerosol-generating substrate in the liquid storage chamber 201 a, to reuse the atomizer 101 d.
In a specific embodiment, as shown in FIG. 27 a and FIG. 27 b , a novel atomization core 20 f is provided, and the bottom surface D of the liquid storage chamber 201 a is formed on the side surface of a sleeve portion 200 c of the atomization core 20 f facing toward the atomization portion 200 d, and the side surface of the surface corresponding to the liquid inlet hole 34 is recessed in a direction facing away from the atomization portion 200 d, to form a groove 35. The liquid inlet hole 34 is specifically provided on the sidewall corresponding to the groove 35 and is in communication with the atomization chamber 220.
In an embodiment, the height of the bottom surface of the groove 35 is the same as the height of the lowest position F of the liquid inlet hole 34. Therefore, when the atomizer 101 c is vertically placed, it can also ensure that a small amount of aerosol-generating substrate in the liquid storage chamber 201 a can pass through the liquid inlet hole 34 to enter the atomization chamber 220, thereby effective ensuring the utilization of the aerosol-generating substrate.
Further, in this embodiment, the bottom surface D of the liquid storage chamber 201 a is lower than the highest position of the liquid inlet hole 34, and the radial size of the groove 35 along the direction perpendicular to the air outlet path C of the atomization core 20 a may be greater than the aperture of the liquid inlet hole 34 along the direction perpendicular to the air outlet path C of the atomization core 20 a, to fully expose the liquid inlet hole 34. The radial size of the groove 35 specifically refers to the width size of the groove 35 along the circumferential direction of the atomization core 20 e.
Further, the bottom surface D of the liquid storage chamber 201 a may be a plane and perpendicular to the forward direction, and the radial size of the groove 35 may gradually decrease in the direction facing away from the liquid storage chamber 201 a, to help the aerosol-generating substrate inside the liquid storage chamber 201 a to converge. Certainly, the bottom surface D of the liquid storage chamber 201 a may also be in a concave-convex shape with specific roughness, an inclined shape, or the like.
In one embodiment, referring to FIG. 28 a to FIG. 28 c , FIG. 28 a is a schematic structural diagram of an atomizer according to another embodiment of this application; FIG. 28 b is a cross-sectional view along a direction B-B of the atomizer shown in FIG. 28 a ; and FIG. 28 c is a schematic overall structural diagram of an atomization core of the atomizer shown in FIG. 28 b . Another atomizer 101 e is provided. This atomizer 101 e may be a closed atomizer. That is, the liquid storage chamber 201 a cannot be refilled.
Specifically, the atomizer 101 e include a housing 10 b and an atomization core 20 g. The atomization core 20 g is arranged inside the housing 10 b, and cooperates with the housing 10 b to form a liquid storage chamber 201 b. Different from the atomizers 101 c and 101 d corresponding to FIG. 26 and FIG. 27 b , the entire outer sidewall of the atomization core 20 g is in contact with and sheathed with the housing 10 b.
In this embodiment, as shown in FIG. 28 c , the liquid inlet hole 34 is specifically provided on the outer sidewall of the atomization core 20 g, and the bottom surface D of the liquid storage chamber 201 b is higher than the highest position of the liquid inlet hole 34. In addition, the atomization core 20 g includes at least one communication hole 36. The communication hole 36 is in communication with different positions of the liquid inlet hole 34. The liquid storage chamber 201 b is specifically in communication with the liquid inlet hole 34 through the at least one communication hole 36. For the specific structures of the atomization core 20 g corresponding to the atomizer 101 e, reference may be made to FIG. 28 a and FIG. 28 b.
In a specific embodiment, as shown in FIG. 28 c , the communication hole 36 may be a slot formed on the outer sidewall of the atomization core 20 g, and the slot runs through the side surface of the atomization core 20 g facing toward the mouthpiece 11 and the liquid inlet hole 34, and cooperates with the housing 10 b to form a liquid inlet channel. The liquid storage chamber 201 b is specifically in communication with the liquid inlet hole 34 through the liquid inlet channel.
Specifically, in this embodiment, as shown in FIG. 28 b and FIG. 28 c , the outer sidewall of the atomization core 20 g may still be sheathed with the first sealing member 26 c, to seal the atomization chamber 220. The first sealing member 26 c may be a silica gel sleeve. In this embodiment, the slot is specifically provided on the outer sidewall of the first sealing member 26 c, and the housing 10 specifically cooperates with the first sealing member 26 c to form the liquid storage chamber 201 b and the liquid inlet channel, to improve the sealing effect of the liquid inlet channel and avoid the leakage problem. It may be understood that, the entire outer sidewall of the first sealing member 26 c is sheathed with the housing 10 b, and the upper surface of the first sealing member 26 c forms the bottom surface D of the liquid storage chamber 201 b.
Certainly, in another embodiment, the communication hole 36 may also be a through hole provided at the middle position of the atomization core 20 g, and the through hole is in direct communication with the atomization chamber 220, to make the liquid storage chamber 201 b and the atomization chamber 220 in communication with each other.
Specifically, as shown in FIG. 28 c , the communication hole 36 may include a first communication hole 36 a and a second communication hole 36 b. The first communication hole 36 a and the second communication hole 36 b are respectively located on opposite sides of the liquid inlet hole 34 along the circumferential direction of the atomization core 20 g, and are respectively in communication with the lowest positions of two opposite sides of the liquid inlet hole 34 in the circumferential direction of the atomization core 20 g. Compared with the solution in which only a single communication hole 36 is provided, the probability of the problem that bubbles are formed in the communication hole 36 and prevent the liquid from being discharged can be reduced.
Further, the communication hole 36 may further include a third communication hole 36 c. The third communication hole 36 c is located between the first communication hole 36 a and the second communication hole 36 b and is in communication with the highest position of the liquid inlet hole 34. In addition, the radial size of the third communication hole 36 c may gradually increase in the direction away from the liquid inlet hole 34, to prevent bubbles from being formed inside the third communication hole 36 c, and bubbles formed inside the first communication hole 36 a or the second communication hole 36 b may be broken through the third communication hole 36 c, to further reduce the probability of the problem of forming bubbles inside the communication hole 36. In some implementations, the plurality of communication holes 36 are connected to the liquid inlet hole 34 in different directions.
It should be noted that the other structures and functions of the atomizers 101 c, 101 d, and 101 e are the same as or similar to the structures and functions of the foregoing atomizers 101 a and 101 b. In addition, the same or similar technical effects may be achieved. For details, reference may be made to the foregoing descriptions. Details are not described herein again.
For the atomizer 101 e provided by this embodiment, the housing 10 b and the atomization core 20 g are arranged such that the atomization core 20 e is arranged inside the housing 10 a, and cooperates with the housing 10 b to form the liquid storage chamber 201 b. The liquid storage chamber 201 b is configured to store the aerosol-generating substrate. In addition, by making the liquid inlet hole 34 opposite to a side surface of the housing 10 b, the bottom surface D of the liquid storage chamber 201 b is higher than the liquid inlet hole 34. The atomization core 20 g includes at least one communication hole 36, for the liquid storage chamber 201 b to communicate with the liquid inlet hole 34 through the communication hole 36 and further communicate with the atomization chamber 220, thereby not only implementing the lateral one-surface liquid inlet of the atomization core 20 g, but also using the at least one communication hole 36 to guide a small amount of aerosol-generating substrate on the bottom surface D of the liquid storage chamber 201 b to the liquid inlet hole 34 and to the atomization chamber 220 for atomization. Further, the aerosol-generating substrate in the liquid storage chamber 201 b is fully atomized, and the residue of the aerosol-generating substrate in the liquid storage chamber 201 b is reduced, to improve the product utilization. In addition, the sufficient aerosol-generating substrate is supplied inside the atomization chamber 220, to reduce the risk of dry heating of the heating component 24.
