Description

Atomizer and atomizing device

Technical Field

The application relates to the technical field of ultrasonic atomization, in particular to an atomizer and an atomizing device.

Background

Smoking articles (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning products by making products that release compounds without burning.

Examples of such products are heat non-combustible devices that release compounds by heating rather than burning materials; for example, the material may be tobacco or other non-tobacco products, which may or may not include nicotine. Electronic nebulizing devices, as another example, typically contain a liquid that is nebulized to produce an inhalable aerosol; the liquid may comprise nicotine and/or a fragrance and/or an aerosol generating substance (e.g. glycerol).

The known electronic atomization device comprises a liquid guide element, wherein in use, a part of the liquid guide element sucks liquid matrix and then transfers the liquid matrix to a part combined with an atomization core for atomization; however, whether the liquid guiding element can smoothly transfer the liquid matrix to the part combined with the atomizing core has great relation to the atomizing effect of the electronic atomizing device and the user experience.

For ease of illustration, the following examples are described with respect to the ultrasonic atomizer 10 being removably connected to the power supply assembly 20.

As shown in fig. 3 to 7, the ultrasonic atomizer 10 includes:

the main body 101 is substantially flat and cylindrical. The body 101 has proximal and distal ends opposite in length; the proximal end is configured as one end of a user for sucking the aerosol, and a suction nozzle opening for the user to suck is arranged at the proximal end; and the distal end is provided as an end to be coupled with the power module 20, and the distal end of the main body 101 is open and has a detachable bottom cover 106 mounted thereon.

The bottom cover 106 is provided with a first electrode hole 1061 and a second electrode hole 1062. The ultrasonic atomization assembly 105 may be electrically coupled to the power module 20 via the first electrode hole 1061 and the second electrode hole 1062. Meanwhile, the bottom cover 106 is further provided with an air inlet 1063 for allowing external air to enter the ultrasonic atomizer 10 during suction. Further, a containing chamber 1065 is further disposed on the bottom cover 106, the first electrode hole 1061 and the second electrode hole 1062 are both located in the containing chamber 1065, and the air inlet 1063 is located outside the containing chamber 1065. Further, a magnetic connector 1064 is provided on the bottom cover 106 to detachably connect the ultrasonic atomizer 10 to the power supply assembly 20.

The interior of the housing is provided with a reservoir a for storing a liquid matrix, a liquid guide element 102 (first liquid guide element) for sucking the liquid matrix from the reservoir a, a liquid guide element 103 (second liquid guide element) for sucking the liquid matrix, a support 104, and an ultrasonic atomization assembly 105 for ultrasonically atomizing the liquid matrix.

A smoke transmission pipe 1011 arranged along the axial direction is arranged in the main body 101, and a liquid storage cavity A for storing liquid matrix is formed in the space between the outer wall of the smoke transmission pipe 1011 and the inner wall of the main body 101; one end of the smoke transmission pipe 1011 is communicated with the suction nozzle, so that the generated aerosol is transmitted to the suction nozzle to be sucked. In a preferred embodiment, the flue gas delivery pipe 1011 and the main body 101 are integrally molded by using a moldable material, and the prepared liquid storage cavity a is open or open towards the far end.

As will be understood in conjunction with fig. 12, the ultrasonic atomizing assembly 105 includes an ultrasonic atomizing plate 1051, first electrical connectors (1052, 1053), a second electrical connector 1054, an insulating seal 1055, and a resistive plate 1056.

The ultrasonic atomization sheet 1051 is substantially circular, and has a first electrode formed on the upper surface (or atomization surface) thereof and a second electrode formed on the lower surface thereof. A first electrical connector (1052, 1053) is held in contact with the first electrode to form an electrical connection; a second electrical connection 1054 is held in contact with the second electrode to form an electrical connection.

The first electrical connector (1052, 1053) includes a conductive sleeve 1052 and a coupling 1053. The ultrasonic atomization sheet 1051, second electrical connector 1054, insulating seal 1055, and resistive plate 1056 are disposed within the conductive sleeve 1052. Wherein the ultrasonic atomization sheet 1051 is horizontally disposed adjacent to the upper end of the conductive sleeve 1052 to maintain the first electrode in contact with the conductive sleeve 1052 to form an electrical connection; one end of the coupling 1053 and the second electrical connector 1054 are both disposed flush near the lower end of the conductive sleeve 1052; the resistive plate 1056 is electrically connected and disposed between the coupling 1053 and the second electrical connector 1054; the insulating seal 1055 is sleeved on the second electric connector 1054 and is arranged between the resistance plate 1056 and the ultrasonic atomization sheet 1051.

The insulating seal 1055 may be made of silicone.

The resistance plate 1056 can consume the energy stored by the ultrasonic atomization 1051 after the ultrasonic atomization sheet 1051 is electrified and disconnected, so that the ultrasonic atomization sheet 1051 can work normally after being electrified again, and the phenomenon that other electronic components are burnt out due to the fact that instantaneous high voltage is released after the ultrasonic atomization sheet 1051 is electrified again is avoided.

After assembly, the ultrasonic atomization assembly 105 is partially housed within the containment chamber 1065, with the first electrode hole 1061 disposed coaxially with the second electrical connector 1054 and the second electrode hole 1062 disposed in correspondence with the coupling 1053.

The liquid guiding member 102 is a layer of organic porous fiber in a sheet or block shape extending in the cross-sectional direction of the body 101. When assembled, fluid conducting element 102 is positioned adjacent to and opposite upper surface of reservoir A and is adapted to draw in liquid matrix and transfer liquid matrix away from the lower surface of reservoir A to contacting fluid conducting element 103, as indicated by arrow R1 in FIG. 7. The liquid guiding element 102 is provided with a plug hole for the flue gas transmission pipe 1011 to penetrate through.

In a preferred embodiment, fluid conducting element 102 is made of an organic porous material having elasticity, and exhibits moderate flexibility and rigidity. In implementation, the fluid-directing element 102 has a modulus of elasticity or stiffness that is less than the material of the body 101 or the material defining the reservoir chamber a and greater than the material of the fluid-directing element 103. In particular to hard artificial cotton with Shore hardness of 20-70A. In alternative implementations, liquid conducting element 102 is a rigid rayon comprising oriented polyester fibers, or a rigid rayon or rayon foam made of filamentary polyurethane, or the like. The above drainage element 102 has hardness or flexibility between that of a common flexible plant cotton/non-woven fabric (shore hardness is less than 20A) and that of a rigid porous ceramic/microporous metal (shore hardness is more than 80A), so that the structure is stable and has extremely low expansion after absorbing and infiltrating a liquid matrix, and after assembly, the drainage element 102 is in contact with the inner wall of the main body 101 or the pipe wall of the smoke output pipe 11 between flexible contact and rigid contact, so that on one hand, the liquid storage cavity A can be independently sealed by utilizing the flexibility of the drainage element, and on the other hand, the drainage element has certain hardness and can be easily fixed and maintained. In particular, as shown in the above figures, the shape of the liquid guiding element 102 is substantially adapted to the opening at the lower end of the reservoir a, which in turn may be used to cover, close and seal the reservoir a. In a more preferred embodiment, the fluid conducting element 102 has a Shore hardness of 50-70A, which is approximately equivalent to a thermoplastic elastomer or silicone.

FIG. 8 shows a topographical view of the surface or cross-section of the drainage element 102 of the above hardness; the liquid guiding element 102 is substantially in the shape of an ellipse, and the insertion hole matched with the flue gas transmission pipe 1011 is also in the shape of an ellipse. The fluid conducting member 102 is made of oriented fibers, such as polyethylene and/or polypropylene, which are substantially aligned in the longitudinal direction, and the oriented fibers are arranged in the longitudinal direction of the fluid conducting member 102, so that the fluid conducting member 102 has the characteristic of strong bending resistance and thus rigidity. In addition, the liquid guide element 102 prepared by the organic fibers can keep sufficient gaps among fiber materials in the preparation process, so that the liquid matrix can be transferred, and the liquid guide element 102 has proper flexibility. The liquid guiding member 102 having the above-oriented fibers is anisotropic. On one hand, the bending strength at least along the length direction is larger than that along the width direction; or on the other hand, has a drainage rate in the length direction that is greater than the drainage rate in the width direction.

Meanwhile, in fig. 8, the surface or the inside of the liquid guiding element 102 is provided with a texture 1021 extending along the length direction; specifically, the grain 1021 is prepared by the textile technology of roller pressing and the like of the oriented fibers, and the space between partial fibers is enlarged by the roller pressing or the spunlace technology and the like in the preparation process, so that macroscopic dents are formed at the positions with the enlarged space, and the width is less than 1mm and is about 0.1-0.5 mm; texture 1021 is formed on or in fluid conducting element 102 by the indentations, which is beneficial for fluid matrix transfer and retention, and for enhanced stiffness.

In the fluid conducting member 102 shown in FIG. 8 of the above embodiment, the fluid conducting member 102 has a length d4 of 16.4mm, a width d5 of 7.80mm, and a thickness of 2.0 mm.

As shown in fig. 9, the liquid guiding member 103 is made of a flexible strip or rod-shaped fiber material, such as cotton fiber, nonwoven fiber, sponge, etc.; the liquid guiding member 103 is configured in a special shape (substantially a left-right symmetrical structure) in assembly, including a first portion 1031 extending in the width direction of the main body 101, a second portion 1032 extending from both end sides of the first portion 1031 in the longitudinal direction of the main body 101 toward the liquid storage chamber a, a third portion 1033 extending from one end of the second portion 1032 in the width direction of the main body 101 (to a second end 1033b of the third portion 1033), and a fourth portion 1034 extending from a first end 1033a of the third portion 1033 in the longitudinal direction of the main body 101 away from the liquid storage chamber a; opposite the second end 1033b, the first end 1033a is disposed against an inner wall of the main body 101. In use, the third portion 1033 contacts the lower surface of the fluid conducting element 102 to draw the liquid matrix from the fluid conducting element 102 for transfer by capillary wetting to the second portion 1032 and hence to the first portion 1031. In other examples, the liquid guiding member 103 may be formed by a plurality of parts separated from each other. It is also understood that, projecting from the vertical direction, the portion of the liquid-guiding element 102 that overlaps the projection of the first surface; in some cases, third portion 1033 may be in only partial contact with the first surface, and in some cases, third portion 1033 may be in full contact with the first surface, such as when wicking element 102 is filled with liquid matrix.

In the ultrasonic atomizer, the liquid substrate is sucked from the liquid guiding element 102 through the liquid guiding element 103, so that the liquid substrate is prevented from being excessively or quickly transferred to the ultrasonic atomization sheet 1051 to cause frying oil.

A holder 104 for sealing at least a part of the reservoir chamber a is further provided in the main body 101 based on the fitting fixation of the liquid guiding member 103 and the liquid guiding member 102. In particular, the amount of the solvent to be used,

as shown in fig. 10 to 11, the bracket 104 has a first end 1041 and a second end 1042 opposite in the longitudinal direction of the main body 101. The first end 1041 is disposed adjacent to the reservoir a and the second end 1042 is disposed adjacent to the bottom cover 106. After assembly, first end 1041 abuts a lower surface of wicking element 102 to at least partially provide retention to wicking element 102; the second end 1042 is retained on the ultrasonic atomization assembly 105 and the bottom cap 106.

The holder 104 has a pair of through holes 1043 symmetrically provided in the thickness direction of the main body 101, and the through holes 1043 are in fluid communication with the reservoir chamber a. A smoke channel 1044 formed by hollow penetration is also arranged between the through holes 1043. The flue gas channel 1044 has a proximal end proximate reservoir a and an opposite distal end.

After assembly, the first portion 1031 of the fluid directing element 103 is retained on the atomizing surface of the ultrasonic atomization plate 1051, the second portion 1032 extends within the through-hole 1043, the third portion 1033 is retained on the first end 1041, and the fourth portion 1034 is retained between the peripheral sidewall 1045 of the bracket 104 and the inner wall of the body 101. The distal end of the smoke channel 1044 is in contact with the first portion 1031 and abuts the first portion 1031 against the atomization surface of the ultrasonic atomization sheet 1051.

In a preferred embodiment, the distal end portion or portion of the smoke channel 1044 is recessed to form a cutaway slot 10441, and the first portion 1031 and/or the second portion 1032 are disposed along the cutaway slot 10441. The notch 10441 is used to facilitate the transfer of the liquid matrix to the ultrasonic atomization sheet 1051 while ensuring that the liquid-directing element 103 is well bonded to the ultrasonic atomization sheet 1051.

In a preferred embodiment, the inner wall of the through hole 1043 has an inclined surface 1043a disposed near the first portion 1031 and inclined toward the outside of the through hole 1043. In some embodiments, the inner wall of the through hole 1043 has a stepped surface disposed near the first portion 1031, or other arrangements that make the space in the through hole near the first portion 1031 larger. By designing the inclined surface 1043a or the stepped surface, a relief space is formed at the end of the through hole 1043 (near the first portion 1031) to avoid that the liquid guiding member 103 is clamped too tightly and the dropping oil is too slow due to inward deformation when the holder 104 is pressed, so that the liquid matrix smoothly flows to the first portion 1031.

The third portion 1033 is held at a portion of the first end portion 1041, and the portion of the first end portion 1041 constitutes a holding portion. In a preferred implementation, the retaining portion has a surface (first surface) that matches the shape of the third portion 1033 and faces the reservoir chamber a to retain the third portion 1033.

In a further preferred implementation, the holding portion has an inclined surface 1041a inclined toward a direction away from the third portion 1033 or toward the through hole 1043, i.e., inclined toward the bottom cover 106; the inclined surface 1041a extends from the through hole 1043 towards the outside of the main body 101, and the inclined surface 1041a prevents the third portion 1033 from being clamped too tightly by the liquid guiding element 102 and the bracket 104 to cause the oil to flow too slowly, so that the liquid matrix can smoothly flow to the second portion 1032 or the through hole 1043. As can be seen from the figure, the liquid guiding member 102, the third portion 1033 and the inclined surface 1041a are arranged in sequence along the longitudinal direction of the main body 101 (the extending direction of the proximal end of the main body 101 toward the distal end), so that the liquid guiding member 102 can press the third portion 1033 against the inclined surface 1041a by its own weight when the liquid substrate is not sucked.

As will be understood from fig. 13, the distance between the inclined surface 1041a and the upper surface of the liquid guiding element 102, or between the inclined surface 1041a and the lower surface of the liquid guiding element 102, increases along the extending direction (the direction indicated by R11 in the figure) of the first end 1033a of the third portion 1033 toward the second end 1033 b. For example: in the direction of R11, d1 is the minimum distance between inclined surface 1041a and the lower surface of liquid guiding member 102, and d2 is the maximum distance between inclined surface 1041a and the lower surface of liquid guiding member 102. Thus, the liquid substrate can be smoothly transferred in the direction indicated by R11. This is desirable, i.e., it is desirable that a substantial majority of the liquid matrix passes toward the through hole 1043 or the second portion 1032, while very little or no liquid matrix passes toward the fourth portion 1034.

In addition, the first end 1033a of the third portion 1033 is clamped between the inclined surface 1041a and the lower surface of the liquid guiding element 102, i.e. at the narrowest point of the inclined surface 1041a and the lower surface of the liquid guiding element 102, while the second end 1033b of the third portion 1033 is at the widest point of the inclined surface 1041a and the lower surface of the liquid guiding element 102. Third portion 1033 when liquid matrix is not being drawn, first end 1033a and second end 1033b of third portion 1033 are both in an initial state and have substantially the same thickness. The first end 1033a of the third portion 1033 is in a clamped state and the second end 1033b of the third portion 1033 is in a loosened state after the third portion 1033 is filled with liquid matrix (i.e., the third portion 103 is in a natural state, the liquid matrix is saturated by the liquid matrix; in other words, the liquid matrix in the reservoir is not reduced by the absorption of the third portion 1033 after the third portion 1033 is filled with liquid matrix; in other words, the liquid matrix in the reservoir is not reduced by the absorption of the third portion 1033; the first end 1033a of the third portion 1033 is in a clamped state; it is apparent that the thickness of the first end 1033a of the third portion 1033 is less than the thickness of the second end 1033b of the third portion 1033.

It is understood that in other examples, the third portion 1033 may be partially in contact with the lower surface of the liquid guiding element 102 or partially supported by the inclined surface 1041 a; in this case, the portion in contact with the lower surface of liquid guiding element 102 also has one end sandwiched between inclined surface 1041a and the lower surface of liquid guiding element 102 and the other end sandwiched between inclined surface 1041a and the widest lower surface of liquid guiding element 102; after imbibing the liquid matrix, the thickness of the one end is less than the thickness of the other end.

The stent 104 is preferably made of a flexible material such as silicone, thermoplastic elastomer. In an embodiment, the circumferential sidewall 1045 of the bracket 104 is provided with a rib extending along the circumferential direction, and the rib is used for sealing a gap between the bracket 104 and the inner wall of the main body 101.

In a preferred implementation, a liquid buffer space may be provided on the holder 104 for storing the liquid matrix to adjust the efficiency of delivery of the liquid matrix to the ultrasonic atomization sheet 1051. For example, a capillary groove 1043b may be provided on a portion of the inner wall of the through hole 1043 near the reservoir a (it should be noted that the capillary groove may simultaneously replenish air to the reservoir a, relieving the negative pressure of the reservoir a caused by the consumption of the liquid substrate); alternatively, a window or cutout surrounding the second portion 1032 may be provided on the peripheral sidewall 1045 of the frame 104, so that at least a portion of the second portion 1032 is exposed to the frame 104, thereby forming a blocking space to prevent the liquid matrix from flowing or transferring to the first portion 1031 more quickly.

In the design of the gas path for releasing and outputting the aerosol, the inner wall of the smoke channel 1044 and the atomizing surface of the ultrasonic atomizing sheet 1051 jointly define an atomizing chamber; the cross section of the flue gas channel 1044 is smaller than that of the flue gas output pipe 1011, and the other end of the flue gas transmission pipe 1011 is sleeved on the proximal end of the flue gas channel 1044; thus, the aerosol after ultrasonic atomization is output through the smoke channel 1044 and the smoke output pipe 1011.

In a preferred embodiment, the support 104 is further provided with an airflow guide 1046 disposed obliquely with respect to the atomization surface, and the distal end portion or partial depression of the smoke channel 1044 forms an airflow slot 10442 to form an airflow outlet of the airflow guide 1046. During suction, external air flows into the ultrasonic atomizer 10 through the air inlets 1063 on the bottom cover 106, flows in through the air inlets of the air flow guide portion 1046, and flows out from the air flow groove 10442 in a direction-changing manner into the smoke channel 1044 or toward the atomizing surface (shown as R2 in the figure), and then the air and the ultrasonically atomized aerosol are output along the smoke channel 1044 and the smoke transmission pipe 1011.

In a further preferred embodiment, the airflow guide portion 1046 includes an airflow guide surface 1046a extending from the flow slot 10442 in a direction obliquely toward the outside of the main body 101 or away from the flow slot 10442, so that the backward airflow can flow out of the flow slot 10442 into the smoke channel 1044 at a preset angle. Like this, through the airflow guide portion 1046 that has this airflow guide face 1046a, the atomizing face blowout that the air can be towards ultrasonic atomization piece 1051 is favorable to the mixture of air and atomizing granule, has promoted the experience of suction and has felt.

In a further preferred embodiment, the thickness (or wall thickness) of the distal end of the smoke channel 1044 is between 0.5mm and 1 mm; preferably, between 0.5mm and 0.8 mm; more preferably, it is between 0.6mm and 0.8 mm. Through the setting of this thickness, guarantee the intensity of flue gas passageway 1044 distal end, cause the problem of flue gas passageway 1044 deformation of turning up when avoiding ultrasonic atomization piece 1051 high frequency vibrations.

The thickness (or wall thickness) of the flue gas channel 1044 may or may not be uniform in the direction extending from the distal end of the flue gas channel 1044 toward the proximal end. In a further preferred embodiment, the thickness of the smoke channel 1044 is gradually increased in the direction extending from the distal end to the proximal end of the smoke channel 1044, while the inner diameter of the smoke channel remains substantially uniform. Like this, on the one hand do benefit to the transmission of the aerosol after the atomizing, on the other hand, further guarantee the intensity of flue gas passageway 1044, cause the problem of flue gas passageway 1044 deformation of turning up when avoiding ultrasonic atomization piece 1051 high frequency vibrations. It will be appreciated that the thickness of the flue gas channel 1044 may be progressively greater throughout its extension; or the thickness in the direction of partial extension may be stepwise increasing, for example: the thickness of the lower portion of the flue gas channel 1044 is gradually increased, while the thickness of the upper portion can be maintained uniform.

In a further preferred embodiment, the ultrasonic atomizer 10 further comprises an air passage for allowing air to enter the reservoir a, so as to supply air to the reservoir a and relieve the reservoir a from negative pressure caused by consumption of the liquid medium.

In an implementation, a portion of the first end 1041 of the bracket 104 near the lower surface of the liquid guiding element 102 is recessed to form a groove 1047, the bracket 104 is further provided with an airflow hole 1048 in fluid communication with the groove 1047, and the first end 1041 is further provided with a notch 10411 in fluid communication with the groove 1047.

A gap is provided between the peripheral side wall extending between the upper and lower surfaces of the liquid guide member 102 and the inner wall of the main body 101, the gap forming a first passage portion of the air passage. The first channel portion extends substantially in the longitudinal direction of the body 101. In a preferred embodiment, ribs 1012 are provided on the inner wall of body 101 and abut against liquid conducting element 102 with ribs 1012, so that a gap is maintained between liquid conducting element 102 and the inner wall of body 101 to form a first passage portion. Further, the peripheral side wall extending between the upper and lower surfaces of liquid guiding member 102 has a straight portion 1022 close to rib 1012, and a gap is maintained between liquid guiding member 102 and the inner wall of main body 101 by abutment of straight portion 1022 and rib 1012.

The recess 1047 forms a second channel portion of the air channel and the airflow hole 1048 forms a third channel portion of the air channel. The upper end surfaces of the airflow holes 1048 are higher than the bottom surface of the recess 1047. Through the groove 1047 arranged on the sealing element, on the basis of relieving the negative pressure in the liquid storage cavity A, the air permeability between the upper surface and the lower surface of the liquid guide element 102 is ensured, and the transfer of liquid matrix is facilitated; further, the groove 1047 can buffer the liquid substrate, which is beneficial to preventing liquid leakage.

The gap between the support 104 and the inner wall of the main body 101 is sealed by the ribs provided on the peripheral side wall 1045 of the support 104. Thus, in use, as the negative pressure in the reservoir chamber Aa is gradually increased with consumption of the liquid substrate, air flowing from the air inlet 1063 into the ultrasonic atomizer 10 can flow only into the recess 1047 through the air flow hole 1048, and then flows to the reservoir chamber a (shown by R3 in the figure) through the notch groove 10411 and the gap between the liquid guide member 102 and the inner wall of the main body 101. Thereby slowing down the negative pressure in the liquid storage cavity A and ensuring the smooth transfer of the liquid matrix.
