[0003] During use of smoking products (e.g., cigarettes and cigars), tobacco is burned to produce tobacco aerosol. People try to replace these tobacco-burning products by manufacturing products that release compounds without burning.

[0004] An example of such products is a heating device that releases a compound by heating rather than burning a material. For example, the material may be tobacco or another non-tobacco product. The non-tobacco product may or may not include nicotine. In another example, there are aerosol-providing products, such as electronic atomization devices. These electronic atomization devices usually include an e-liquid, and the e-liquid is heated to vaporize, to generate an inhalable aerosol. In a known electronic atomization device, for example, a patent CN202220773164.8, an e-liquid storage cavity is separated by a tubular element arranged in the e-liquid storage cavity, an e-liquid matrix is absorbed by an annular e-liquid guide element arranged in the tubular element, and a cylindrical heating network externally wrapped by the annular e-liquid guide element heats the e-liquid matrix, to generate an aerosol.SUMMARY

[0036] For ease of understanding of the present application, the present application is described in further detail below with reference to the accompanying drawings and specific implementations.

[0037] An embodiment of the present application provides an electronic atomization device. Referring to FIG. 1, the electronic atomization device includes an atomizer 100 for storing an e-liquid matrix and atomizing the e-liquid matrix to form an aerosol, and a power supply mechanism 200 for supplying power to the atomizer 100. In the embodiment shown in FIG. 1, the atomizer 100 and the power supply mechanism 200 of the electronic atomization device may be detachable relative to each other. Such an electronic atomization device in which the atomizer 100 and the power supply mechanism 200 are detachable relative to each other is, for example, a so-called "pod-replaceable" electronic atomization device. Alternatively, in some modified embodiments, the atomizer 100 and the power supply mechanism 200 of the electronic atomization device are tightly wrapped and fixed by a housing component of the electronic atomization device, so that the atomizer 100 and the power supply mechanism 200 cannot be detachable relative to each other from the interior of the housing component. Such an electronic atomization device in which the atomizer 100 and the power supply mechanism 200 are non-detachable relative to each other is, for example, a so-called "integrated or disposable" electronic atomization device.

[0038] In an optional embodiment, for example, as shown in FIG. 1, the power supply mechanism 200 includes a receiving cavity 2170 disposed at one end in a length direction and configured to receive and accommodate at least a portion of the atomizer 100, and an electrical contact 2130 at least partially exposed in the receiving cavity 2170 and configured to form, when at least a portion of the atomizer 100 is received and accommodated in the power supply mechanism 200, an electrical connection with the atomizer 100 to supply power to the atomizer 100.

[0039] According to the embodiment shown in FIG. 1, an electrical contact 21 is disposed at an end portion of the atomizer 100 opposite to the power supply mechanism 200 in the length direction, so that when at least a portion of the atomizer 100 is received in the receiving cavity 2170, the electrical contact 21 is in contact with and abuts against the electrical contact 2130 to conduct electricity.

[0040] A sealing member 2160 is disposed in the power supply mechanism 200, and at least a portion of an internal space of the power supply mechanism 200 is separated by the sealing member 2160 to form the foregoing receiving cavity 2170. In the embodiment shown in FIG. 1, the sealing member 2160 is constructed to extend in a longitudinal direction of the power supply assembly 200, and is preferably made of a flexible material such as silica gel, to prevent the e-liquid matrix seeping from the atomizer 100 to the receiving cavity 2170 from flowing to a controller 2120, a sensor 2150, and other components inside the power supply assembly 200.

[0041] In the embodiment shown in FIG. 1, the power supply mechanism 200 further includes: a battery cell 2110 for power supply, disposed at the other end facing away from the receiving cavity 2170 in the length direction; and a controller 2120 disposed between the battery cell 2110 and the receiving cavity 2170. The controller 2120 is operable to conduct current between the battery cell 2110 and the electrical contact 2130.

[0042] The power supply mechanism 200 includes a sensor 2150, configured to sense an inhalation airflow generated by the atomizer 100 during inhalation, so that the controller 2120 controls the battery cell 2110, based on a detection signal of the sensor 2150, to supply power to the atomizer 100.

[0043] In the embodiment shown in FIG. 1, a charging interface 2140 is disposed at the other end of the power supply mechanism 200 facing away from the receiving cavity 2170. The charging interface 2140 is configured to supply power to the battery cell 2110.

[0044] FIG. 2 to FIG. 8 show schematic structural diagrams of an embodiment of an atomizer 100 in FIG. 1. The atomizer 100 includes a housing 10. The housing 10 is approximately hollow cylindrical and is internally provided with necessary functional components for storing and atomizing an e-liquid matrix. The housing 10 has a proximal end 110 and a distal end 120 opposite to each other in a longitudinal direction. According to a requirement of common use, the proximal end 110 is configured as an end for a user to inhale an aerosol, and an air outlet 113 for the user to inhale is provided at the proximal end 110. The distal end 120 is used as an end combined with the power supply mechanism 200, and a distal end 120 of the housing 10 is open, on which a detachable support 20 is mounted. The open structure is configured to mount each functional component to the interior of the housing 10.

[0045] In the embodiments shown in FIG. 2 to FIG. 8, the electrical contact 21 penetrates from a surface of the support 20 to the interior of the atomizer 100, so that the electrical contact 21 is at least partially exposed out of the atomizer 100, and is in contact with the electrical contact 2130 to form conduct electricity. Meanwhile, the support 20 is further provided with an air inlet 22 for allowing external air to enter the atomizer 100 during inhalation. In addition, as shown in FIG. 2 to FIG. 8, the exposed portion of the electrical contact 21 is flush with the surface of the support 20 after assembly.

[0046] According to the embodiments shown in FIG. 2 to FIG. 8, the housing 10 includes a first housing portion 111 and a second housing portion 112. The first housing portion 111 is close to or defines the proximal end 110, and the second housing portion 112 is close to or defines the distal end 120. A width dimension of the first housing portion 111 is greater than a width dimension of the second housing portion 112. Additionally or alternatively, a thickness dimension of the first housing portion 111 is greater than a thickness dimension of the second housing portion 112. Further, a step is formed between the first housing portion 111 and the second housing portion 112. In use, the second housing portion 112 of the housing 10 can be received in the receiving cavity 2170 of the power supply mechanism 200, and establishes a conductive connection with the power supply mechanism 200. In addition, the first housing portion 111 is exposed out of the receiving cavity 2170, and the step defined between the first housing portion 111 and the second housing portion 112 abuts against an end portion of the power supply mechanism 200, to provide a stop for the atomizer 100 received in the receiving cavity 2170.

[0047] As shown in FIG. 2 to FIG. 8, a first clamping protrusion 13 is arranged on the second housing portion 112, to form a connection with a matching structure such as a clamping hole on the power supply mechanism 200 when the atomizer 100 is received in the receiving cavity 2170 of the power supply mechanism 200, thereby stably holding the atomizer 100 in the receiving cavity 2170 of the power supply mechanism 200.

[0048] Referring to FIG. 2 to FIG. 8, an e-liquid storage cavity 12 for storing an e-liquid matrix and an atomization assembly for absorbing the e-liquid matrix from the e-liquid storage cavity 12 and heating and atomizing the e-liquid matrix are disposed inside the housing 10. In the schematic cross-sectional view shown in FIG. 7, an axially disposed aerosol outlet tube 11 is arranged in the housing 10. The space between an outer surface of the aerosol outlet tube 11 and an inner surface of the housing 10 forms the e-liquid storage cavity 12 for storing the e-liquid matrix. A first end of the aerosol outlet tube 11 adjacent to the proximal end 110 is in communication with the air outlet 113, to deliver the generated aerosol to the air outlet 113 for user inhalation. As shown in FIG. 7, the aerosol outlet tube 11 and the housing 10 are integrally molded from a moldable material. Consequently, the e-liquid storage cavity 12 formed after molding is closed on the side of the proximal end 110 and open on the side facing the distal end 120.

[0049] Referring to FIG. 2 to FIG. 7, a first e-liquid guide element 50 is further disposed in the housing 10. The first e-liquid guide element 50 is a sheet-like or block-like fiber arranged perpendicular to a longitudinal direction of the housing 10. In some embodiments, the first e-liquid guide element 50 is made of a flexible capillary fiber material, such as natural cotton fiber or non-woven fabric fiber. Specifically, the first e-liquid guide element 50 includes sheet-like e-liquid guide cotton. Alternatively, in some modified embodiments, the first e-liquid guide element 50 includes artificial cotton, or rigid artificial cotton or artificial foam made of filamentous polyurethane. For example, the first e-liquid guide element 50 uses a 138# rigid synthetic organic polymer fiber, and has a density of 0.1 mg / mm 3< to 0.9 mg / mm 3< . An entire weight of the first e-liquid guide element 50 when not immersed in an e-liquid is approximately 0.04 g to 0.06 g. The first e-liquid guide element 50 is made of oriented fiber oriented and aligned substantially in a length direction, a width direction, or a radial direction. The arrangement of the oriented fiber in the length direction or the width direction of the first e-liquid guide element 50 allows the first e-liquid guide element 50 to exhibit a relatively strong bending resistance and thus present a rigid feature. Specifically, for example, the first e-liquid guide element 50 is rigid artificial cotton including oriented polyester fiber, or rigid artificial cotton or artificial foam made of filamentous polyurethane.

[0050] Referring to FIG. 3 to FIG. 8, the first e-liquid guide element 50 is accommodated and mounted in the support 20. Further, after assembly, the first e-liquid guide element 50 and the support 20 jointly close an opening of the e-liquid storage cavity 12 facing the distal end 120. Since the support 20 is dense, the e-liquid matrix in the e-liquid storage cavity 12 after assembly can substantially only be absorbed by the first e-liquid guide element 50 to leave the e-liquid storage cavity 12.

[0051] Referring to FIG. 2 to FIG. 8, a first surface 510 of the first e-liquid guide element 50 adjacent to the e-liquid storage cavity 12 is in flow communication with the e-liquid storage cavity 12, so as to absorb the e-liquid matrix. Further, after assembly, the first e-liquid guide element 50 closes and defines a portion of a boundary of the e-liquid storage cavity 12. As shown in FIG. 2 to FIG. 7, the first e-liquid guide element 50 is constructed to be annular with an insertion hole 51.

[0052] As shown in FIG. 2 to FIG. 8, a tubular element 14 is further disposed in the housing 10. The tubular element 14 is an independent component, and is preferably made of a relatively thin rigid material. As a proper example, the tubular element 14 is a ceramics tube, a stainless steel tube, or the like. After penetrating the insertion hole 51 of the first e-liquid guide element 50 in an axial direction, the tubular element 14 is connected to the aerosol output tube 11 in interference or close fitting or interference fitting, and also sealed while being securely connected.

[0053] Referring to FIG. 3 to FIG. 8, the atomization assembly is accommodated and assembled in the tubular element 14. The tubular element 11 is provided with a plurality of through holes 142 spaced apart circumferentially. The atomization assembly is in flow communication with the first e-liquid guide element 50 through the through holes 142 to receive the e-liquid matrix. In addition, in the embodiment shown in FIG. 7, the through holes 142 on the tubular element 14 are substantially covered by an inner surface of the insertion hole 51 of the first e-liquid guide element 50.

[0054] Referring to FIG. 3 to FIG. 8, in some embodiments, the atomization assembly includes a second e-liquid guide element 30. The second e-liquid guide element 30 is flexible in this embodiment, for example, is made of flexible fiber such as cotton fiber, non-woven fabric fiber, or sponge. The second e-liquid guide element 30 is constructed to be a tube or a cylinder arranged in the longitudinal direction of the housing 10. The second e-liquid guide element 30 is coaxial with the tubular element 14 and is located in the tubular element 14. Alternatively, in some modified embodiments, the second e-liquid guide element 30 may further include a rigid porous element, for example, porous ceramic or porous glass.

[0055] In an embodiment, an outer side surface of the second e-liquid guide element 30 in a radial direction covers or communicates with the through hole 142, so that the outer side surface of the second e-liquid guide element 30 is configured as an e-liquid absorbing surface, to receive and absorb the e-liquid matrix from the first e-liquid guide element 50 through the through hole 142, as shown by arrow R1 in FIG. 7 and FIG. 8. An inner side surface of the second e-liquid guide element 30 in a radial direction is configured as an atomization surface, and the atomization surface is combined with / attached to / abuts against the heating element 40. Further, after being delivered to the atomization surface, the e-liquid matrix is heated and atomized by the heating element 40 to generate an aerosol to be released.

[0056] As shown in FIG. 3 to FIG. 8, in this embodiment, the heating element 40 is arranged to extend in the longitudinal direction of the housing 10 or the second e-liquid guide element 30. The heating element 40 is arranged coaxially with the second e-liquid guide element 30. In some optional embodiments, the heating element 40 is a resistive heating mesh, a resistive heating coil, or the like. In this embodiment, the heating element 40 is a heating element that is rolled by using a sheet-like or mesh-like substrate. The rolled heating element 40 is not a closed tube in the circumferential direction, but a cylinder with a side opening in the longitudinal direction. A conductive pin 41 and a conductive pin 42 are soldered or arranged at both ends of the heating element 40, for guiding current on the heating element 40.

[0057] In the embodiments shown in FIG. 7 and FIG. 8, the second e-liquid guide element 30 is at least partially located at an inner side of the first e-liquid guide element 50, and is surrounded by the first e-liquid guide element 50.

[0058] Referring to FIG. 3 to FIG. 8, the support 20 extends into the housing 10 from the distal end 120, thereby supporting and fixing the first e-liquid guide element 50 and the tubular element 14. The support 20 is generally cylindrical in shape. The support 20 is rigid. For example, the support 20 is made of a rigid polymer plastic.

[0059] As shown in FIG. 3 to FIG. 10, in some embodiments, the support 20 includes a first supporting portion 210, a second supporting portion 220, and a third supporting portion 230 that are sequentially arranged in the longitudinal direction. The third supporting portion 230 is combined with and closes the distal end 120 of the housing 10, and the third supporting portion 230 after assembly is partially exposed out of the distal end 120 of the housing 10. The first supporting portion 210, the second supporting portion 220, and the third supporting portion 230 are partially located in the housing 10. The air inlet 22 is also arranged on an exposed surface of the third supporting portion 230 that is exposed out of the housing 10.

[0060] An outer diameter of the second supporting portion 220 is less than outer diameters of the first supporting portion 210 and the third supporting portion 230. Therefore, the second supporting portion 220 is recessed relative to the first supporting portion 210 and the third supporting portion 230.

[0061] As shown in FIG. 3 to FIG. 10, a first accommodating cavity 240 is defined in the first supporting portion 210, to accommodate and hold the first e-liquid guide element 50. After assembly, the first supporting portion 210 surrounds the first e-liquid guide element 50. The first supporting portion 210 is in interference fit with the housing 10 close to the e-liquid storage cavity 12. A first sealing element 271, such as an O-ring, surrounding the first supporting portion 210 is arranged outside the first supporting portion 210, to provide sealing between the first supporting portion 210 and the housing 10. Specifically, a first mounting slot 216 circumferentially surrounding the first supporting portion 210 is arranged on an outer side surface of the first supporting portion 210, and the first sealing element 271 such as the O-ring is mounted in the first mounting slot 216.

[0062] As shown in FIG. 3 to FIG. 10, the third supporting portion 230 establishes a mechanical connection and an interference fit with the housing 10 close to the distal end 120. Specifically, a connection structure 232 such as a clamping slot or a clamping projection may be arranged on the third supporting portion 230, to establish a mechanical connection with the housing 10. A second sealing element 272, such as an O-ring, surrounding the third supporting portion 230 is arranged outside the third supporting portion 230, to provide sealing between the third supporting portion 230 and the housing 10. Specifically, a second mounting slot 233 circumferentially surrounding the third supporting portion 230 is arranged on an outer side surface of the third supporting portion 230, and the second sealing element 272 such as the O-ring is mounted in the second mounting slot 233.

[0063] As shown in FIG. 3 to FIG. 10, a plurality of flanges 221 circumferentially surrounding the second supporting portion 220 and grooves 222 located between adjacent flanges 221 are further arranged outside the second supporting portion 220 of the support 20. In addition, in this embodiment, the flanges 221 are spaced apart from an inner surface of the housing 10, so that the flanges 221 do not abut against the inner surface of the housing 10. Specifically, as shown in FIG. 7, a distance d1 between the flanges 221 and the inner surface of the housing 10 is approximately 2 mm to 5 mm.

[0064] Referring to FIG. 7 to FIG. 10, the flanges 221 and the grooves 222 are defined between the first sealing element 271 and the second sealing element 272.

[0065] As shown in FIG. 7 and FIG. 8, after assembly, the through hole 142 of the tubular element 14 is substantially surrounded and covered by the first e-liquid guide element 50, so that the e-liquid matrix is delivered from an inner surface of the insertion hole 51 of the first e-liquid guide element 50 to the atomization assembly located in the tubular element 14. In some embodiments, the through hole 142 may have a diameter of approximately 2 mm to 8 mm.

[0066] As shown in FIG. 7 and FIG. 8, the first e-liquid guide element 50 substantially completely covers the through hole 142 of the tubular element 14. After assembly, the through hole 142 of the tubular element 14 is substantially opposite to the first e-liquid guide element 50 and is exposed out of the first e-liquid guide element 50 only to a height of approximately 1 mm in the axial direction.

[0067] As shown in FIG. 3 to FIG. 10, a plurality of first recessed structures 215 are arranged on an inner side surface of the first accommodating cavity 240 of the support 20. When the first e-liquid guide element 50 is accommodated and mounted in the first accommodating cavity 240, a first gap is formed between the first recessed structure 215 and an outer side surface 530 of the first e-liquid guide element 50, so as to buffer a small amount of e-liquid matrix, thereby helping to smoothly deliver the e-liquid matrix to the atomization assembly in the tubular element 14 via the first e-liquid guide element 50. The first recessed structure 215 is spaced apart from an inner bottom wall of the first accommodating cavity 240, to prevent leakage while e-liquid storage is implemented.

[0068] When the first e-liquid guide element 50 is received and assembled in the first accommodating cavity 240, a first surface 510 of the first e-liquid guide element 50 is substantially level with an opening of the first accommodating cavity 240. Alternatively, when the first e-liquid guide element 50 is accommodated and assembled in the first accommodating cavity 240, the first surface 510 of the first e-liquid guide element 50 is substantially level with the upper end of the support 20.

[0069] As shown in FIG. 3 to FIG. 10, a second accommodating cavity 250 extending from the first accommodating cavity 240 to the second supporting portion 220 is further arranged in the support 20. The second accommodating cavity 250 extends from the first supporting portion 210 to the second supporting portion 220. The second accommodating cavity 250 is configured to accommodate and mount at least a portion of the tubular element 14 and / or the atomization assembly. Specifically, after assembly, at least a portion of the tubular element 14 is inserted into the second accommodating cavity 250 of the support 20 after passing through the first accommodating cavity 240. In addition, the tubular element 14 and the support 20 are sealed by interference fit. In addition, there is no flexible sealing element between the tubular element 14 and the support 20. As shown in FIG. 3 to FIG. 14, after assembly, a portion of the tubular element 14 extends into the support 20, and another portion extends out of the support 20. For example, after assembly, the tubular element 14 has an exposed portion 141 extending out of the support 20 and / or the first e-liquid guide element 50. The exposed portion 141 forms a close-fitting connection with the aerosol output tube 11.

[0070] As shown in FIG. 3 to FIG. 10, the cross-sectional area of the first accommodating cavity 240 of the support 20 is greater than the cross-sectional area of the second accommodating cavity 250, so that a step is formed on the inner bottom wall of the first accommodating cavity 240. The first e-liquid guide element 50 is accommodated in the first accommodating cavity 240, surrounded by the first supporting portion 210, and stopped against the step of the inner bottom wall of the first accommodating cavity 240. A plurality of second recessed structures 242 surrounding the second accommodating cavity 250 are arranged on the inner bottom wall of the first accommodating cavity 240 of the support 20. After assembly, the second recessed structure 242 defines a second gap between the inner bottom wall of the first accommodating cavity 240 and a second surface 520 of the first e-liquid guide element 50, so as to buffer the e-liquid matrix seeping out from the second surface 520 of the first e-liquid guide element 50. The second recessed structure 242 satisfies the dimension relationship: length>width>depth.

[0071] As shown in FIG. 10, a third recessed structure 252 extending in the longitudinal direction is arranged on an inner surface of the second accommodating cavity 250. The third recessed structure 252 is connected to at least one second recessed structure 242. Further, the third recessed structure 252 defines a third gap between the inner surface of the second accommodating cavity 250 and the outer surface of the tubular element 14, to store the e-liquid matrix. In a preferred embodiment, during assembly, the through hole 142 of the tubular element 14 is oriented relative to the third recessed structure 252 by means of positioning. As shown in FIG. 10, a positioning protrusion 253 is further arranged on the inner surface of the second accommodating cavity 250. The positioning protrusion 253 is spaced apart from and aligned with the third recessed structure 252 in the longitudinal direction. Correspondingly, an end portion of the tubular element 14 inserted into the second accommodating cavity 250 has a positioning notch and the like. The positioning protrusion 253 cooperates with the positioning notch to provide positioning during insertion of the tubular element 14 into the second accommodating cavity 250.

[0072] As shown in FIG. 7 to FIG. 10, an air inlet channel is arranged on the support 20, to provide a channel for air in the air inlet 22 to enter the second accommodating cavity 250. The complete air inlet channel includes: a first channel portion 23, extending from the air inlet 22 in the longitudinal direction of the support 20 or penetrating into the groove 222 on the surface of the second supporting portion 220, where after passing through the first channel portion 23, external air entering the air inlet 22 is released into the groove 222; at least one groove 222; and a second channel portion 25 extending from the groove 222 on the surface of the second supporting portion 220 to or penetrating to the second accommodating cavity 250, to deliver air to the atomization assembly in the second accommodating cavity 250, where the second channel portion 25 may include a plurality of bent sections.

[0073] For a flow path of an airflow during absorption, refer to arrow R2 in FIG. 7 to FIG. 10. External air entering the air inlet 22 flows into the groove 222 on the surface of the second supporting portion 220 through the first channel portion 23, and then flows to the second channel portion 25 through the groove 222. Finally, the air enters the tubular element 14 from the second channel portion 25, and is delivered from the aerosol output tube 11 to the air outlet 113 by carrying an aerosol generated by the atomization assembly.

[0074] As shown in FIG. 10, in the radial direction of the support 20, a first communication port of the first channel portion 23 and the groove 222 is arranged opposite to a second communication port of the second channel portion 25 and the groove 222. In the longitudinal direction of the support 20, the first communication port between the first channel portion 23 and the groove 222 and the second communication port between the second channel portion 25 and the groove 222 are at different longitudinal heights. Specifically, in FIG. 10, the first communication port between the first channel portion 23 and the groove 222 is closer to the third supporting portion 230 than the second communication port between the second channel portion 25 and the groove 222.

[0075] As shown in FIG. 7 to FIG. 10, the support 20 further defines an air exchange channel, to provide a flow path for air to enter the e-liquid storage cavity 12. Therefore, when the e-liquid matrix in the e-liquid storage cavity 12 is gradually consumed to reduce a negative pressure in the e-liquid storage cavity 12, the air can enter the e-liquid storage cavity 12 via the air exchange channel, to relieve or eliminate the negative pressure in the e-liquid storage cavity 12. Specifically, the air exchange channel includes: a vent hole 261 penetrating from the outer side surface of the first supporting portion 210 to an inner wall of the first accommodating cavity 240, where specifically, the vent hole 261 avoids the second supporting portion 220; and a vent slot 262 arranged on an inner surface of the first accommodating cavity 250, where the vent slot 262 extends longitudinally from the vent hole 261 to the upper end of the support 20. In this embodiment, the vent hole 261 has a diameter of approximately 0.3 mm to 2.0 mm. In addition, the vent slot 262 has a width and / or depth of approximately 0.3 mm to 2.0 mm. When the negative pressure in the e-liquid storage cavity 12 is relatively low, as shown by arrow R3 in FIG. 7 to FIG. 10, air sequentially enters the e-liquid storage cavity 12 via the vent hole 261 and the vent slot 262, to eliminate or relieve the negative pressure in the e-liquid storage cavity 12.

[0076] As shown in FIG. 9, to avoid or prevent a port of the vent hole 261 located on an outer surface of the first supporting portion 210 from being closed or blocked by the housing 10, an avoidance notch 263 surrounding the vent hole 261 is arranged on the outer surface of the first supporting portion 210. The port of the vent hole 261 located on the outer surface of the first supporting portion 210 is kept smooth through the avoidance notch 263, so that air can enter the air exchange channel.

[0077] As shown in FIG. 3 and FIG. 4, the atomizer 100 having the foregoing structure is advantageous for modular assembly. Specifically, during modular preparation and assembly, the tubular element 14 accommodating the atomization assembly therein may be first inserted into the second accommodating cavity 250 of the support 20, and then the first e-liquid guide element 50 is accommodated in the first accommodating cavity 240 after passing through the tubular element 14, to obtain a module 300 shown in FIG. 4. Then, the module 300 is inserted into the housing 10 from the distal end 120 of the housing 10 as shown by arrow P1 in FIG. 4, so that the tubular element 14 is combined with the aerosol output tube 11 in the housing 10 by close fitting, and the assembled atomizer 100 in FIG. 7 may be obtained.

[0078] In some embodiments, the aerosol outlet tube 11 and the housing 10 are integrally molded from a moldable material. In addition, in an embodiment, the aerosol output tube 11 and the housing 10 are molded from a transparent polymer material, so that the aerosol output tube 11 and the housing 10 are both transparent. In addition, during or after assembly, the exposed portion 141 of the tubular element 14 that extends out of the first e-liquid guide element 50 is visible through the surface of the housing 10, which is beneficial to viewing or monitoring, during assembly, whether the tubular element 14 is correctly riveted and press-fitted to the aerosol output tube 11.

[0080] As shown in FIG. 11 to FIG. 14, the electronic atomization device further includes a support 20a, arranged between the battery cell 16a and the e-liquid storage cavity 12a, to accommodate and support the first e-liquid guide element 50a and the tubular element 14a. The support 20a includes a first supporting portion 210a, a second supporting portion 220a, and a third supporting portion 230a sequentially arranged in the longitudinal direction.

[0082] A second accommodating cavity 250a is defined in the second supporting portion 220a, to at least partially mount and accommodate the tubular element 14a and the atomization assembly.

[0083] The third supporting portion 230a is connected to the housing 10a by means of riveting or buckling.

In this embodiment, most of the flanges 221a substantially abut against an inner surface of the housing 10a or are close to the inner surface of the housing 10a.

[0085] As shown in FIG. 12 to FIG. 14, the second accommodating cavity 250a of the support 20a has an inner diameter enlarged section 254a close to the first accommodating cavity 240a. An inner diameter of the inner diameter enlarged section 254a increases in a direction close to the first accommodating cavity 240a. An inner surface of the inner diameter enlarged section 254a is obliquely arranged. After assembly, the through hole 142a of the tubular element 14a is opposite to the inner diameter enlarged section 254a. In addition, in some examples, at least a portion of the through hole 142a of the tubular element 14a is staggered from the first e-liquid guide element 50a, so that the through hole 142a of the tubular element 14a is not partially covered or blocked by an inner surface of the first e-liquid guide element 50a.

[0086] As shown in FIG. 12, after assembly, an e-liquid buffer space 255a surrounding the through hole 142a is defined by the inner diameter enlarged section 254a. The e-liquid buffer space 255a is in fluid communication with a second surface 520a of the first e-liquid guide element 50a. In use, the e-liquid matrix in the e-liquid storage cavity 12a is absorbed via the first surface 510a of the first e-liquid guide element 50a, and then flows out, via the second surface 520a, to the e-liquid buffer space 255a defined by the inner diameter enlarged section 254a. Finally, the through hole 142a passing through the tubular element 14a is absorbed by the second e-liquid guide element 30a, as shown by arrow R1 in FIG. 11 and FIG. 12.

[0087] As shown in FIG. 12, the first e-liquid guide element 50a surrounds or covers only a portion of the through hole 142a of the tubular element 14a and avoids a portion of the through hole 142a of the tubular element 14a. In this embodiment, a portion of the second e-liquid guide element 30a is surrounded by the first e-liquid guide element 50a, or a portion of the second e-liquid guide element 30a extends into the first e-liquid guide element 50a.

[0088] As shown in FIG. 13 and FIG. 14, the support 20a further defines an air inlet channel, to provide an airflow path through which air enters the second accommodating cavity 250a. The air inlet channel includes: a first channel portion 23a, passing through the third supporting portion 230a to the groove 222a on the outer side surface of the second supporting portion 220a; the groove 222a; and a second channel portion 25a extending from the groove 222a to the second accommodating cavity 250a. During inhalation, air passes through the third supporting portion 230a via the first channel portion 23a and enters the groove 222a, is circumferentially delivered to the second channel portion 25a via the groove 222a, and then passes through the atomization assembly and is delivered to the air outlet 113a by the aerosol output tube 11a.

[0089] A first communication port between the first channel portion 23a and the groove 222a and a second communication port between the second channel portion 25a and the groove 222a are staggered circumferentially. In addition, the first communication port between the first channel portion 23a and the groove 222a and the second communication port between the second channel portion 25a and the groove 222a are opposite circumferentially. In addition, the first communication port between the first channel portion 23a and the groove 222a and the second communication port between the second channel portion 25a and the groove 222a are at different longitudinal heights. Specifically, the first communication port between the first channel portion 23a and the groove 222a is closer to the e-liquid storage cavity 12a than the second communication port between the second channel portion 25a and the groove 222a.

[0090] As shown in FIG. 13 and FIG. 14, the support 20a further defines an air exchange channel, to provide a channel path for air to enter the e-liquid storage cavity 12a. When a negative pressure in the e-liquid storage cavity 12a exceeds a predetermined threshold, air enters the e-liquid storage cavity 12a via the air exchange channel, to relieve the negative pressure in the e-liquid storage cavity 12a. The air exchange channel includes: a vent hole 261a, extending from a lower surface of the first supporting portion 210a to an inner bottom wall of the first accommodating cavity 240a in the longitudinal direction; and a vent slot 262a, extending on an inner side surface of the first accommodating cavity 240a in the longitudinal direction, where when the first e-liquid guide element 50a is accommodated or held in the first accommodating cavity 240a, a slit or a gap between the inner side surface of the first accommodating cavity 240a and an outer side surface 530a of the first e-liquid guide element 50a is defined by the vent slot 262a. Air enters the first accommodating cavity 240a through the vent hole 261a, and enters the e-liquid storage cavity 12a via the vent slot 262a, as shown by arrow R3 in FIG. 11 to FIG. 14.

[0091] As shown in FIG. 11 to FIG. 14, an air inlet end of the vent hole 261a communicates with the groove 222a of the second supporting portion 220a, so as to provide air outside the second supporting portion 220a to enter the air exchange channel.

[0092] As shown in FIG. 11 to FIG. 14, an annular convex edge 256a is further arranged in the second accommodating cavity 250a of the support 20a.

During assembly, the tubular element 14a is inserted between the annular convex edge 256a and the inner surface of the second accommodating cavity 250a. In FIG. 11 and FIG. 12, the convex edge 256a abuts against and supports the second e-liquid guide element 30a in the longitudinal direction, so as to at least partially support the second e-liquid guide element 30a.

[0093] As shown in FIG. 11 to FIG. 14, a third cavity 235a is further defined in the third supporting portion 230a of the support 20a. After assembly, the electrical contact 2130a at least partially extends into the third cavity 235a. In addition, in the third cavity 235a, a conductive lead of the heating element 40a is in contact with or is soldered to the electrical contact 2130a to form a conductive connection. In addition, as shown in FIG. 11 to FIG. 14, the third supporting portion 230a is connected to a contact base 2131a surrounding the electrical contact 2130a.
