Optionally, the oil cup 341 is in interference fit with the oil cover 342 to improve the connection stability between the oil cup 341 and the oil cover 342. Alternatively, the oil reservoir 341 may be stamped from a thin-walled metal material.

In some embodiments, the number of the second outlet ports 345 is at least two, and all the second outlet ports 345 are spaced on the oil cover 342. Specifically, all the second air outlets 345 are formed at intervals on the oil reservoir cover 342 by punching. Thus, the sufficient smoke output amount can be ensured, and the feeling of the suction port 32 can be ensured. In some embodiments, the second inlet ports 344 include at least two, and all of the second inlet ports 344 are spaced apart from the reservoir cup 341. Specifically, all of the second intake ports 344 are formed at intervals in the reservoir cup 341 by punching. So, can guarantee that sufficient hot gas flow supplies with, from the atomization effect who promotes the tobacco tar, and then guarantee user's suction and experience.

In a preferred embodiment, the second outlet ports 345 include at least two, all of the second outlet ports 345 are spaced apart from the oil reservoir cap 342, and the second inlet ports 344 include at least two, all of the second inlet ports 344 are spaced apart from the oil reservoir cup 341. Specifically, all of the second outlet ports 345 and all of the second inlet ports 344 are disposed opposite to the oil reservoir cover 342 and the oil reservoir cup 341, respectively.

In some embodiments, the oil storage bin 34 further comprises a second gauze 352, wherein the second gauze 352 is disposed in the oil storage cavity 346 and is located between the second air inlet 344 and the oil storage cotton 343. Specifically, the second gauze 352 may be a medical gauze, and is disposed between the oil-storing cotton 343 and the second air inlet 344 to ensure that the hot air uniformly contacts with the oil-storing cotton 343, so as to atomize the tobacco tar uniformly, thereby improving the taste of the user.

In the preferred embodiment, the oil storage bin 34 further comprises a first gauze 351 and a second gauze 352, the first gauze 351 is disposed in the oil storage cavity 346 and is located between the second air outlet 345 and the oil storage cotton 343, and the second gauze 352 is disposed in the oil storage cavity 346 and is located between the second air inlet 344 and the oil storage cotton 343. Therefore, the mouthfeel of the user can be effectively improved.

In some embodiments, the cartomizer 30 further includes a first silicone gel 36 disposed in the mounting cavity 33, a fixed cavity is formed inside the first silicone gel, and the oil storage chamber 34 is replaceably mounted in the fixed cavity. Specifically, the fixed cavity opened on the first silica gel 36 has a shape similar to that of the oil storage bin 34. For example, the oil sump 34 has a rectangular parallelepiped shape and the fixing cavity has a rectangular parallelepiped shape, but in order to fix the oil sump 34, the fixing cavity is sized slightly smaller than the oil sump 34 so that the oil sump 34 is in interference fit with the cavity wall of the fixing cavity.

In practical use, when the atomizing bomb 30 is assembled, the oil storage bin 34 can be fixed by using the elastic force of the first silica gel 36, when the oil storage bin 34 is replaced, the oil storage bin 34 to be replaced is pulled out by overcoming the elastic force of the first silica gel 36, and then a new oil storage bin 34 is installed in the fixing cavity for fixing. Thus, compared with the disposable electronic atomization device 100, the oil storage bin 34 is replaceably installed in the fixed cavity, so that the oil storage bin 34 can be continuously used only by replacing the new oil storage bin 34 after the smoke oil in the oil storage bin 34 is pumped out, thereby avoiding resource waste; compared with the electronic atomization device 100 capable of repeatedly injecting oil, the hot air flow entering from the outside replaces the atomization core to atomize the tobacco tar to form smoke, so that the problem of taste reduction caused by aging of the atomization core can be avoided.

The first silicone rubber 36 is installed in a direction from the oil storage bin 34 to the suction port 32. Specifically, the positioning groove is formed by digging the surface of one side of the first silica gel 36 facing the positioning element, and is in a step shape. In practical use, after the positioning member is inserted into the positioning groove, the first silicone rubber 36 is prevented from moving to the suction port 32.

In order to prevent the oil storage bin 34 from rubbing against the wall of the mounting cavity 33 during the assembly process, in some embodiments, the atomizing bullet 30 further includes a second silica gel 37, the second silica gel 37 is disposed in the mounting cavity 33 and located on one side of the oil storage bin 34 close to the suction port 32, and the oil storage bin 34 elastically abuts against the second silica gel 37. In practical use, when the oil storage bin 34 extends from the fixing cavity to the second silica gel 37, the elastic force provided by the second silica gel 37 is applied. Thus, the oil sump 34 can be prevented from rubbing against the wall of the mounting chamber 33.

When the atomized bullet 30 is assembled, in the first step, the oil storage bin 34 and other parts except the oil storage bin 34 in the atomized bullet 30 are assembled respectively; in the second step, the oil storage tank 34 is placed into the fixing cavity from the end of the suction nozzle far away from the suction port 32 and fixed. When the tobacco tar in the oil storage bin 34 is used up and the oil storage bin 34 needs to be replaced, the used oil storage bin 34 is firstly pulled out from the fixed cavity, and then a new oil storage bin 34 is placed into the fixed cavity again and fixed.

The number of the third air outlets 182 may be one, or at least two, in this embodiment, at least two, and are uniformly spaced on the fixing cover 184, so as to improve the outflow uniformity of the hot air flow and improve the uniformity of the atomized tobacco tar.

Further, the hot gas bin 18 further comprises a sealing ring 186, and the sealing ring 186 seals a gap between the fixed seat 183 and the fixed cover 184.

Specifically, the battery assembly 10 further includes a support base 20 and a support cover 21 disposed in the accommodating cavity 12, the support base 20 is coupled to the support cover 21, and the battery cell 16 is positioned between the support base 20 and the support cover 21. In practical use, the support base 20 is hollowed out to allow the electric core 16 to be placed therein, and the support cover 21 is inserted into the support base 20 from a direction facing the electric core 16, so that the electric core 16 is fixed between the support cover 21 and the support base 20.

Referring to fig. 5, at least a portion of the heating element 17 is disposed in the heat storage cavity 13, the heating element 17 includes a supporting portion 173, a first leveling layer 174, a metal paste layer 171 and a connecting portion 172, the supporting portion 173 is supported on the cavity wall of the heat storage cavity 13, the first leveling layer 174 is sandwiched between the supporting portion 173 and the metal paste layer 171, and the metal paste layer 171 is electrically connected to the battery cell 16 through the connecting portion 172. Specifically, the supporting portion 173 is made of a high temperature resistant material, such as a metal material or a ceramic material, and is fixed on the ceramic base 185, the metal paste layer 171 (such as a nickel layer or a chromium layer) has a resistance value, and generates heat when being energized, and the connecting portion 172 may be a conductive wire capable of conducting electricity. In practical use, the external air flow is controlled to enter the accommodating cavity 12 from the first air inlet 14, then flows to the metal slurry layer 171 from the inside of the accommodating cavity 12 and is heated by the metal slurry layer 171 to form a hot air flow, and the hot air flow is stored in the heat storage cavity 13 and can flow from the heat storage cavity 13 to the first air outlet 15 to be discharged under the action of the external suction force.

It should be understood that, regardless of whether the metal supporting portion 173, the ceramic supporting portion 173, or the supporting portion 173 made of other materials, the surface is uneven, if the metal paste layer 171 is directly printed on the supporting portion 173 by a printing process, the resistance value will be non-uniform at various positions on the surface of the supporting portion 173, so that the resistance value of the metal paste layer 171 is not controllable, the heating effect of the metal paste layer 171 is affected, and the taste of the user is reduced.

Therefore, the first leveling layer 174 is interposed between the metal paste layer 171 and the support portion 173. The surface of the first smoothing layer 174 is smooth, so that the resistance value of the metal paste layer 171 is uniform after printing thereon, and the resistance value of the metal paste layer 171 is controllable, thereby ensuring that the metal paste layer 171 is uniformly heated, and further ensuring the taste of a user. If the support 173 is the support 173 made of a metal material, the first planarization layer 174 may be made of an insulating material to function as an insulator for the first planarization layer 174 and the support 173 and to protect the first planarization layer 174, thereby improving the lifespan of the metal paste layer 171. Specifically, the first leveling layer 174 may be a glaze layer, or may be another material as long as it has a smooth, flat and insulating surface.

Further, the heat generating member 17 further includes a second leveling layer 175, and the second leveling layer 175 is attached to the surface of the metal paste layer 171 remote from the first leveling layer 174. In actual use, the second leveling layer 175 can prevent the metal paste layer 171 from being worn, improve the service life of the metal paste layer 171, and can play a role in improving the beauty of the heat generating member 17 due to the flat surface. Specifically, the second leveling layer 175 may be a glaze layer, or may be other materials as long as it has the characteristics of smooth and flat surface and wear resistance.

Further, the battery assembly 10 further includes a heat equalizing member 19, and the heat equalizing member 19 is provided in the heat storage chamber 13 on a flow path of the air flow from the heat generating member 17 to the first air outlet 15, and is configured to enable the hot air flow flowing thereto from the heat generating member 17 to be uniformly discharged from the first air outlet 15. In actual use, the hot air flow uniformly discharged from the first air outlet 15 can uniformly atomize the tobacco tar, so that the formed smoke is uniform, thereby ensuring the taste. Specifically, the soaking member 19 is a metal plate having mesh holes, and the plane of the metal plate intersects with the flow direction of the hot gas flow. Preferably, the plane of the metal plate is perpendicular to the flowing direction of the hot air flow, and the hot air flow can be uniformly discharged after passing through the meshes on the metal plate.

Referring to fig. 3 and 6, in actual use, a user sucks air from the suction opening 32, and external air flows into the accommodating cavity 12 from the first air inlet 14 under the action of the suction force, then flows to the heat generating member 17 and is heated by the heat generating member 17 to form a hot air flow, and the hot air flow is stored in the heat storage cavity 13. The hot air flow in the heat storage chamber 13 can further enter the installation chamber 33 from the first air outlet 15, and then enter the oil storage chamber 346 from the second air inlet 344 to contact with the tobacco tar, and the hot air flow can atomize the tobacco tar to form smoke which can be sucked by the user. The smoke enters the installation cavity 33 through the second air outlet 345, and is discharged through the suction opening 32 to enter the user body. Because the hot air flow has mild atomization effect and wide contact area with tobacco tar, the atomization is uniform, the phenomenon that the tobacco tar is burnt and burnt is effectively prevented, and the mouth feel of a user is favorably improved.

Referring to fig. 3 and 7, the battery assembly 10 further includes a control panel 22. The control panel 22 is positioned between the cradle cover 21 and the cradle base 20 and is electrically connected to the heat generating member 17 to control the heating power of the heating wire. Specifically, the control panel 22 may be a PCBA motherboard. When assembling the control panel 22, firstly, the control panel 22 is placed in the hollowed part of the bracket holder 20, then the electric core 16 is placed, and then the bracket cover 21 is covered on the bracket holder, so that the control panel 22 and the electric core 16 are fixed at the same time. In actual use, if a user needs to increase the suction amount, the control panel 22 controls the heating power of the heating element 17 to increase, and the temperature of hot air flow is increased; if the user needs to reduce the suction amount, the control panel 22 controls the heating power of the heating element 17 to be reduced, and the temperature of the hot air flow is reduced.

The battery assembly 10 also includes an airflow sensor 23. Airflow sensor 23 is disposed in a flow path of airflow in accommodation chamber 12, and is electrically connected to battery cell 16. The battery cell 16 is controlled to provide power to the heating wire when the airflow sensor 23 senses airflow flowing. Specifically, the airflow sensor 23 may be a microphone, and when the microphone detects a pressure difference generated by airflow flowing, the microphone sends a start signal to the electrical core 16, so that the electrical core 16 is controlled to be started and supplies power to the heater, and the heater 17 heats.

In some embodiments, a charging port 24 (e.g., a serial line interface, also called a USB interface) electrically connected to the battery cell 16 is further provided on the housing to facilitate charging of the battery cell 16. Specifically, the charging port 24 is located on a side of the housing away from the cartomizer 30. Further, the battery pack 10 further includes a skin 25. A cover 25 is attached to the outer surface of the housing to facilitate gripping by a user. Further, the battery pack 10 also includes a key 26, and the key 26 integrates a display function. Specifically, the key 26 correspondingly displays different information according to the number of times of pressing by the user, for example, when the key is pressed once, the temperature of the hot air flow is displayed; pressing down twice will display the remaining capacity of cell 16.
