[0069] In order to facilitate the understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and specific implementation methods.

[0070] One embodiment of the present application proposes an electronic atomization device, as shown in FIG1 , comprising an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply mechanism 200 that supplies power to the atomizer 100. In the embodiment shown in FIG1 , the atomizer 100 and the power supply mechanism 200 of the electronic atomization device are detachable relative to each other; an electronic atomization device having such an atomizer 100 and a power supply mechanism 200 that are detachable relative to each other, such as a so-called "replaceable cartridge" electronic atomization device. Or in some other variations, the atomizer 100 and the power supply mechanism 200 of the electronic atomization device are tightly wrapped and fixed by a shell 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 inside of the shell component. An electronic atomization device having such an atomizer 100 and a power supply mechanism 200 that are not detachable relative to each other, such as a so-called "integrated or disposable" electronic atomization device.

[0071] In an optional embodiment, such as shown in Figure 1, the power supply mechanism 200 includes a receiving cavity 2170 arranged at one end along the length direction for receiving and accommodating at least a portion of the atomizer 100, and an electrical contact 2130 at least partially exposed in the receiving cavity 2170, which is used to form an electrical connection with the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated in the power supply mechanism 200, thereby supplying power to the atomizer 100.

[0072] According to the embodiment shown in FIG1 , an electrical contact 21 is provided on the end portion of the atomizer 100 opposite to the power supply mechanism 200 along the length direction. When at least a portion of the atomizer 100 is received in the receiving cavity 2170 , the electrical contact 21 contacts and abuts against the electrical contact 2130 to thereby form electrical conduction.

[0073] A sealing member 2160 is provided within the power supply mechanism 200, and the sealing member 2160 partitions at least a portion of the internal space of the power supply mechanism 200 to form the receiving chamber 2170. In the embodiment shown in FIG1 , the sealing member 2160 is configured to extend in a longitudinal direction perpendicular to the power supply mechanism 200 and is preferably made of a flexible material such as silicone, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving chamber 2170 from flowing toward components such as the controller 2120 and the sensor 2150 located within the power supply mechanism 200.

[0074] In the embodiment shown in Figure 1, the power supply mechanism 200 also includes a battery cell 2110 for power supply at the other end away from the receiving cavity 2170 along the length direction; and a controller 2120 arranged between the battery cell 2110 and the receiving cavity 2170, which is operable to guide current between the battery cell 2110 and the electrical contact 2130.

[0075] The power supply mechanism 200 includes a sensor 2150 for sensing the suction airflow generated by the atomizer 100 during suction. The controller 2120 then controls the battery cell 2110 to supply power to the atomizer 100 according to a detection signal from the sensor 2150 .

[0076] In the embodiment shown in FIG. 1 , the power supply mechanism 200 is provided with a charging interface 2140 at the other end away from the receiving cavity 2170 , and the charging interface 2140 is used to charge the battery cell 2110 .

[0077] Figures 2 to 8 show a schematic structural diagram of an embodiment of the nebulizer 100 in Figure 1, wherein the nebulizer 100 includes a shell 10, which is roughly hollow cylindrical and contains necessary functional components for storing and atomizing a liquid matrix; the shell 10 has a proximal end 110 and a distal end 120 opposite to each other in the longitudinal direction; wherein, according to the requirements of common use, the proximal end 110 is configured as the end for the user to inhale the aerosol, and an air outlet 113 for the user to inhale is provided at the proximal end 110; and the distal end 120 is used as the end combined with the power supply mechanism 200, and the distal end 120 of the shell 10 is open, on which a detachable bracket 20 is installed, and the open structure is used to install various functional components into the interior of the shell 10.

[0078] In the embodiment shown in Figures 2 to 8 , the electrical contact 21 extends from the surface of the bracket 20 into the interior of the atomizer 100, and thus at least partially exposed outside the atomizer 100, thereby forming electrical contact with the electrical contact 2130. Furthermore, the bracket 20 is provided with an air inlet 22 for allowing external air to enter the atomizer 100 during inhalation. As shown in Figures 2 to 8 , after assembly, the exposed portion of the electrical contact 21 is flush with the surface of the bracket 20.

[0079] According to the embodiment shown in Figures 2 to 8, the housing 10 includes a first housing portion 111 and a second housing portion 112. The first housing portion 111 is adjacent to or defines the proximal end 110, and the second housing portion 112 is adjacent to or defines the distal end 120. The width of the first housing portion 111 is greater than the width of the second housing portion 112; and / or the thickness of the first housing portion 111 is greater than the thickness of the second housing portion 112. Furthermore, 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 within the receiving cavity 2170 of the power supply mechanism 200, establishing an electrically conductive connection therewith. Furthermore, the first housing portion 111 is exposed outside the receiving cavity 2170, and the step defined between the first housing portion 111 and the second housing portion 112 abuts against the end of the power supply mechanism 200, thereby securing the atomizer 100 when received in the receiving cavity 2170.

[0080] As shown in Figures 2 to 8, a first latch 13 is arranged on the second shell portion 112, which is used to form a connection with an adapting structure such as a latch hole on the power supply mechanism 200 when the atomizer 100 is received in the receiving cavity 2170 of the power supply mechanism 200, so that the atomizer 100 is stably held in the receiving cavity 2170 of the power supply mechanism 200.

[0081] As shown in Figures 2 to 8 , the housing 10 is internally provided with a liquid storage chamber 12 for storing a liquid matrix, and an atomization assembly for drawing the liquid matrix from the liquid storage chamber 12 and heating and atomizing the liquid matrix. In the cross-sectional schematic diagram shown in Figure 7 , an axially arranged aerosol delivery tube 11 is disposed within the housing 10. The space between the outer surface of the aerosol delivery tube 11 and the inner surface of the housing 10 forms the liquid storage chamber 12 for storing the liquid matrix. The first end of the aerosol delivery tube 11, opposite the proximal end 110, is connected to an air outlet 113, thereby transmitting the generated aerosol to the air outlet 113 for inhalation by the user. As shown in Figure 7 , the aerosol delivery tube 11 and the housing 10 are integrally molded from a moldable material. The resulting liquid storage chamber 12 is closed on the proximal end 110 and open on the side facing the distal end 120.

[0082] As shown in Figures 2 to 7, a first liquid-conducting element 50 is further provided in the housing 10. The first liquid-conducting element 50 is a layer of sheet-shaped or block-shaped fibers arranged perpendicular to the longitudinal direction of the housing 10. In some embodiments, the first liquid-conducting element 50 is made of a flexible capillary fiber material, such as natural cotton fiber, non-woven fiber, etc.; specifically, the first liquid-conducting element 50 includes sheet-shaped liquid-conducting cotton. Or in some other variations, the first liquid-conducting element 50 includes artificial cotton, or hard artificial cotton or artificial foam made of filamentous polyurethane. For example, the first liquid-conducting element 50 uses 138# hard synthetic organic polymer fiber with a viscosity of 0.1mg / mm 3 ~0.9mg / mm 3 The density of the first liquid-conducting element 50 is approximately 0.04g to 0.06g when not wetted with liquid. The first liquid-conducting element 50 is made of oriented fibers that are generally oriented along the length, width, or radial direction. The arrangement of the oriented fibers along the length or width of the first liquid-conducting element 50 provides the first liquid-conducting element 50 with a strong bending resistance and thus a rigid property. Specifically, for example, the first liquid-conducting element 50 is a rigid artificial cotton comprising oriented polyester fibers, or a rigid artificial cotton or artificial foam comprising filamentous polyurethane.

[0083] 3 to 8 , the first liquid-conducting element 50 is housed and installed within the bracket 20. After assembly, the first liquid-conducting element 50 and the bracket 20 together seal the opening of the liquid storage cavity 12 toward the distal end 120. Since the bracket 20 is dense, after assembly, the liquid matrix within the liquid storage cavity 12 can essentially only be absorbed by the first liquid-conducting element 50 and then leave the liquid storage cavity 12.

[0084] As shown in Figures 2 through 8 , the first liquid-conducting element 50 is adjacent to the first surface 510 of the liquid reservoir 12 and is in fluid communication with the liquid reservoir 12, thereby drawing liquid matrix. After assembly, the first liquid-conducting element 50 seals and partially defines the boundaries of the liquid reservoir 12. As shown in Figures 2 through 7 , the first liquid-conducting element 50 is configured in an annular shape with an insertion hole 51.

[0085] As shown in Figures 2 to 8, a tubular element 14 is further provided in the housing 10. The tubular element 14 is an independent component and is preferably made of a thinner rigid material. As a suitable example, the tubular element 14 is a ceramic tube or a stainless steel tube. After the tubular element 14 axially penetrates the plug hole 51 of the first liquid-conducting element 50, it is connected to the aerosol output tube 11 by an interference fit, a tight fit, or an interference fit, thereby forming a seal between them while tightening the connection.

[0086] As shown in Figures 3 to 8 , the atomizer assembly is housed and assembled within the tubular element 14. The tubular element 14 is provided with a plurality of circumferentially spaced perforations 142. The atomizer assembly is in fluid communication with the first liquid-conducting element 50 through these perforations 142 to receive the liquid matrix. In the embodiment shown in Figure 7 , the perforations 142 on the tubular element 14 are substantially covered by the inner surface of the insertion hole 51 of the first liquid-conducting element 50.

[0087] 3 to 8 , in some embodiments, the atomizer assembly includes a second liquid-conducting element 30. In this embodiment, the second liquid-conducting element 30 is flexible, for example, made of flexible fibers such as cotton fibers, non-woven fabrics, or sponges. The second liquid-conducting element 30 is configured to be tubular or cylindrical and arranged along the longitudinal direction of the housing 10. The second liquid-conducting element 30 is coaxial with the tubular element 14 and is located within the tubular element 14. Alternatively, in some alternative embodiments, the second liquid-conducting element 30 may also include a rigid porous element, such as porous ceramic or porous glass.

[0088] In this embodiment, the radially outer surface of the second liquid-conducting element 30 covers or communicates with the perforations 142, and thus the outer surface of the second liquid-conducting element 30 is configured as a liquid-absorbing surface to receive and absorb the liquid matrix from the first liquid-conducting element 50 through the perforations 142, as indicated by arrow R1 in Figures 7 and 8. The radially inner surface of the second liquid-conducting element 30 is configured as an atomizing surface, which is coupled to, attached to, or abuts against the heating element 40. After the liquid matrix is ​​transferred to the atomizing surface, it is heated and atomized by the heating element 40 to generate an aerosol, which is then released.

[0089] As shown in Figures 3 to 8, in this embodiment, the heating element 40 is arranged to extend longitudinally along the housing 10 or the second liquid-conducting element 30, and the heating element 40 is arranged coaxially with the second liquid-conducting element 30. In some optional embodiments, the heating element 40 is a resistive heating mesh, a resistive heating coil, etc. In this embodiment, the heating element 40 is a heating element wound from a sheet or mesh-like substrate; the wound heating element 40 is not a closed tubular shape in the circumferential direction, but rather a cylindrical shape with side openings along the longitudinal direction. Conductive pins 41 and 42 are welded or arranged at both ends of the heating element 40 to guide current through the heating element 40.

[0090] In the embodiment shown in FIG. 7 and FIG. 8 , the second liquid-conducting element 30 is at least partially located inside the first liquid-conducting element 50 and is surrounded by the first liquid-conducting element 50 .

[0091] As shown in Figures 3 to 8, the stent 20 extends from the distal end 120 into the housing 10, thereby providing support and fixation for the first liquid-conducting element 50 and the tubular element 14. The stent 20 is generally cylindrical in shape. The stent 20 is rigid, for example, made of a hard polymer plastic.

[0092] As shown in Figures 3 to 10, in some embodiments, the bracket 20 includes a first support portion 210, a second support portion 220, and a third support portion 230 arranged in sequence along the longitudinal direction. The third support portion 230 engages and seals the distal end 120 of the housing 10, and after assembly, a portion of the third support portion 230 is exposed outside the distal end 120 of the housing 10. Portions of the first support portion 210, the second support portion 220, and the third support portion 230 are located within the housing 10. The air inlet 22 is also located on the exposed surface of the third support portion 230 that is exposed outside the housing 10.

[0093] The outer diameter of the second supporting portion 220 is smaller than the outer diameters of the first supporting portion 210 and the third supporting portion 230 , thereby causing the second supporting portion 220 to be recessed relative to the first supporting portion 210 and the third supporting portion 230 .

[0094] As shown in Figures 3 to 10, a first accommodating cavity 240 is defined within the first support portion 210 for accommodating and retaining the first liquid-conducting element 50; after assembly, the first support portion 210 surrounds the first liquid-conducting element 50. The first support portion 210 has an interference fit with the housing 10 near the liquid storage cavity 12. A first sealing element 271, such as an O-ring, is disposed around the outside of the first support portion 210 to provide a seal between the first support portion 210 and the housing 10. Specifically, a first mounting groove 216 is disposed on the outer surface of the first support portion 210, circumferentially surrounding the first support portion 210, and the first sealing element 271, such as an O-ring, is mounted within the first mounting groove 216.

[0095] As shown in Figures 3 to 10 , the third support portion 230 establishes a mechanical connection and interference fit with the housing 10 near the distal end 120. Specifically, a connecting structure 232, such as a latching groove or a latching protrusion, can be provided on the third support portion 230 to establish a mechanical connection with the housing 10. A second sealing element 272, such as an O-ring, is disposed around the third support portion 230 to provide a seal between the third support portion 230 and the housing 10. Specifically, a second mounting groove 233 is disposed on the outer surface of the third support portion 230, circumferentially surrounding the third support portion 230. The second sealing element 272, such as an O-ring, is mounted within the second mounting groove 233.

[0096] As shown in Figures 3 to 10 , the second support portion 220 of the bracket 20 is further provided with a plurality of flanges 221 circumferentially surrounding the second support portion 220, as well as grooves 222 located between adjacent flanges 221. In this embodiment, the flanges 221 are spaced apart from the inner surface of the housing 10, so that the flanges 221 do not abut the inner surface of the housing 10. Specifically, as shown in Figure 7 , the distance d1 between the flanges 221 and the inner surface of the housing 10 is approximately 2 mm to 5 mm.

[0097] 7 to 10 , the flange 221 and the groove 222 are defined between the first sealing element 271 and the second sealing element 272 .

[0098] As shown in Figures 7 and 8, after assembly, the through-hole 142 of the tubular element 14 is substantially surrounded and covered by the first liquid-conducting element 50, thereby transferring the liquid matrix to the atomizing assembly located within the tubular element 14 via the inner surface of the insertion hole 51 of the first liquid-conducting element 50. In some embodiments, the through-hole 142 may have a diameter of approximately 2 mm to 8 mm.

[0099] As shown in Figures 7 and 8, the first liquid-conducting element 50 basically completely covers the through-hole 142 of the tubular element 14; after assembly, the through-hole 142 of the tubular element 14 is basically opposite to the first liquid-conducting element 50 and only about 1 mm in height is exposed outside the first liquid-conducting element 50 in the axial direction.

[0100] As shown in Figures 3 to 10, the inner surface of the first accommodating cavity 240 of the bracket 20 is arranged with a plurality of first recessed structures 215. When the first liquid-conducting element 50 is accommodated and installed in the first accommodating cavity 240, a first gap is formed between the first recessed structures 215 and the outer surface 530 of the first liquid-conducting element 50, which is used to buffer a small amount of liquid matrix, thereby helping to maintain a steady rate of liquid matrix transfer from the first liquid-conducting element 50 to the atomizing assembly within the tubular element 14. The first recessed structures 215 are spaced from the inner bottom wall of the first accommodating cavity 240, thereby storing liquid while preventing leakage.

[0101] When the first liquid-conducting element 50 is accommodated and assembled in the first accommodating cavity 240, the first surface 510 of the first liquid-conducting element 50 is basically flush with the opening of the first accommodating cavity 240; or, when the first liquid-conducting element 50 is accommodated and assembled in the first accommodating cavity 240, the first surface 510 of the first liquid-conducting element 50 is basically flush with the upper end of the bracket 20.

[0102] As shown in Figures 3 to 10 , the bracket 20 further includes a second accommodating cavity 250 extending from the first accommodating cavity 240 into the second support portion 220. The second accommodating cavity 250 extends from the first support portion 210 to the second support portion 220. The second accommodating cavity 250 is used to accommodate and mount at least a portion of the tubular element 14 and / or the atomizer assembly. Specifically, after assembly, at least a portion of the tubular element 14 is inserted into the second accommodating cavity 250 of the bracket 20 after passing through the first accommodating cavity 240. Furthermore, an interference fit forms a seal between the tubular element 14 and the bracket 20. Furthermore, no flexible sealing element is present between the tubular element 14 and the bracket 20. As shown in Figures 3 to 14, after assembly, a portion of the tubular element 14 extends into the bracket 20, and another portion extends outside the bracket 20; for example, after assembly, the tubular element 14 has an exposed portion 141 extending outside the bracket 20 and / or the first liquid-conducting element 50, and the exposed portion 141 forms a tight connection with the aerosol output tube 11.

[0103] As shown in Figures 3 to 10 , the cross-sectional area of ​​the first accommodating cavity 240 of the bracket 20 is larger than that of the second accommodating cavity 250, thereby forming a step on the inner bottom wall of the first accommodating cavity 240. The first liquid-conducting element 50 is housed within the first accommodating cavity 240, surrounded by the first support portion 210, and rests against the step on the inner bottom wall of the first accommodating cavity 240 to form a stop. Several second recessed structures 242 are arranged on the inner bottom wall of the first accommodating cavity 240 of the bracket 20, surrounding the second accommodating cavity 250. After assembly, these second recessed structures 242 define a second gap between the inner bottom wall of the first accommodating cavity 240 and the second surface 520 of the first liquid-conducting element 50, which is used to buffer liquid matrix that seeps from the second surface 520 of the first liquid-conducting element 50. The second recessed structures 242 are longer than they are wide, and their width is greater than their depth.

[0104] As shown in Figure 10 , a third recessed structure 252 extending longitudinally is disposed on the inner surface of the second accommodating cavity 250. This third recessed structure 252 engages with at least one of the second recessed structures 242. 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 for storing the liquid medium. In a preferred embodiment, during assembly, the through-hole 142 of the tubular element 14 is aligned with the third recessed structure 252 through positioning. As shown in Figure 10 , a positioning protrusion 253 is also disposed on the inner surface of the second accommodating cavity 250. This positioning protrusion 253 is longitudinally spaced from and aligned with the third recessed structure 252. Correspondingly, a positioning notch is provided on the end of the tubular element 14 inserted into the second accommodating cavity 250. The interaction between the positioning protrusion 253 and the positioning notch provides positioning during insertion of the tubular element 14 into the second accommodating cavity 250.

[0105] As shown in Figures 7 to 10, an air intake channel is arranged on the bracket 20 to provide a channel for the air from the air inlet 22 to enter the second accommodating cavity 250. The complete air intake channel includes:

[0106] The first channel portion 23 extends from the air inlet 22 along the longitudinal direction of the bracket 20 or penetrates into the groove 222 on the surface of the second support portion 220; the external air entering through the air inlet 22 passes through the first channel portion 23 and is released into the groove 222;

[0107] At least one groove 222; a second channel portion 25, extending from the groove 222 on the surface of the second support portion 220 to or through the second accommodating cavity 250, so as to deliver air to the atomizing assembly in the second accommodating cavity 250; the second channel portion 25 may include multiple bent sections.

[0108] The airflow path during inhalation is shown by arrow R2 in Figures 7 to 10. The external air entering from the air inlet 22 flows into the groove 222 on the surface of the second support part 220 through the first channel part 23, and then flows to the second channel part 25 through the groove 222; finally, it enters the tubular element 14 from the second channel part 25, and carries the aerosol generated by the atomization component to be delivered from the aerosol output tube 11 to the air outlet 113.

[0109] As shown in FIG10 , along the radial direction of the bracket 20, the first communication opening between the first channel portion 23 and the groove 222 is arranged opposite to the second communication opening between the second channel portion 25 and the groove 222. Along the longitudinal direction of the bracket 20, the first communication opening between the first channel portion 23 and the groove 222 is at a different longitudinal height than the second communication opening between the second channel portion 25 and the groove 222. Specifically, in FIG10 , the first communication opening between the first channel portion 23 and the groove 222 is closer to the third support portion 230 than the second communication opening between the second channel portion 25 and the groove 222.

[0110] As shown in Figures 7 to 10 , the support 20 further defines a ventilation channel for providing a flow path for air to enter the liquid storage chamber 12. Thus, when the liquid matrix in the liquid storage chamber 12 is gradually consumed, resulting in a low negative pressure in the liquid storage chamber 12, air can enter the liquid storage chamber 12 through the ventilation channel to relieve or eliminate the negative pressure in the liquid storage chamber 12. Specifically, the ventilation channel includes:

[0111] The vent hole 261 extends from the outer surface of the first support portion 210 to the inner wall of the first accommodating cavity 240 . Specifically, the vent hole 261 avoids the second support portion 220 .

[0112] Vent groove 262 is disposed on the inner surface of first accommodating chamber 250 and extends longitudinally from vent hole 261 to the upper end of bracket 20. In an embodiment, vent hole 261 has a diameter of approximately 0.3 mm to 2.0 mm, and vent groove 262 has a width and / or depth of approximately 0.3 mm to 2.0 mm. When the negative pressure within liquid storage chamber 12 is low, as indicated by arrow R3 in Figures 7 to 10, air enters liquid storage chamber 12 through vent hole 261 and vent groove 262, thereby eliminating or alleviating the negative pressure within liquid storage chamber 12.

[0113] As shown in Figure 9, in order to avoid or prevent the port of the vent hole 261 located on the outer surface of the first support part 210 from being closed or blocked by the shell 10, an avoidance gap 263 is arranged around the vent hole 261 on the outer surface of the first support part 210, and the port of the vent hole 261 located on the outer surface of the first support part 210 is kept unobstructed through the avoidance gap 263, so that air can enter the ventilation channel.

[0114] As shown in Figures 3 and 4, the nebulizer 100 with the above structure is advantageous for modular assembly; specifically, in the modular preparation and assembly, the tubular element 14 containing the nebulizer assembly can be first inserted into the second accommodating cavity 250 of the bracket 20, and then the first liquid-conducting element 50 is passed through the tubular element 14 and accommodated in the first accommodating cavity 240 to obtain the module 300 shown in Figure 4; and then, along the arrow P1 in Figure 4, the module 300 is inserted from the distal end 120 of the shell 10 into the shell 10, and the tubular element 14 is tightly combined with the aerosol output tube 11 in the shell 10, thereby obtaining the assembled nebulizer 100 shown in Figure 7.

[0115] In some embodiments, the aerosol delivery tube 11 is integrally molded with the housing 10 from a moldable material. Furthermore, in some embodiments, the aerosol delivery tube 11 and the housing 10 are molded from a transparent polymer material, thereby making both the aerosol delivery tube 11 and the housing 10 transparent. Furthermore, during or after assembly, the exposed portion 141 of the tubular element 14 extending outside the first liquid-conducting element 50 is visible through the surface of the housing 10, which facilitates checking or monitoring whether the tubular element 14 is correctly riveted and tightly fitted to the aerosol delivery tube 11 during assembly.

[0116] FIG11 and FIG12 are schematic diagrams of an electronic atomization device according to another embodiment; in this embodiment, the electronic atomization device includes:

[0117] The housing 10a can be formed of one component or defined by multiple components. The housing 10a is used to define the outer surface of the electronic atomization device. The housing 10a has a proximal end 110a and a distal end 120a that are opposite to each other in the longitudinal direction.

[0118] an air outlet 113a, arranged at the proximal end 110a;

[0119] an aerosol output tube 11a extending from the air outlet 113a toward the distal end 120a;

[0120] A liquid storage chamber 12a for storing a liquid matrix, the liquid storage chamber 12a being defined between the aerosol output tube 11a and the housing 10a; the liquid storage chamber 12a being closed on a side close to the proximal end 110a and open on a side away from the proximal end 110a;

[0121] The first liquid-guiding element 50a is arranged perpendicular to the longitudinal direction of the electronic atomization device; a first surface 510a of the first liquid-guiding element 50a facing the proximal end 110a is in fluid communication with the liquid storage chamber 12a to draw liquid matrix from the liquid storage chamber 12a;

[0122] The tubular element 14a extends longitudinally along the electronic atomization device and is coupled to the aerosol output tube 11a. The tubular element 14a passes through the first liquid-conducting element 50a. A perforation 142a is provided on the wall of the tubular element 14a.

[0123] The atomization assembly includes a second liquid-conducting element 30a and a heating element 40a; the second liquid-conducting element 30a receives the liquid matrix through the perforation 142a on the wall of the tubular element 14a; the heating element 40a is used to heat at least a portion of the liquid matrix in the second liquid-conducting element 30a to generate an aerosol;

[0124] The battery cell 16a, located near the distal end 120a, is used to supply power to the heating element 40a;

[0125] Circuit board 2120a, used to control the battery cell 16a to supply power to the heating element 40a;

[0126] The electrical contact 2130a extends longitudinally and is arranged between the circuit board 2120a and the atomizer assembly. The electrical contact 2130a is connected to the circuit board 2120a by welding or other means; the conductive leads at both ends of the heating element 40a are welded or abutted against the electrical contact 2130a to establish a conductive connection with the circuit board 2120a, so that the electrical contact 2130a guides the current between the circuit board 2120a and the heating element 40a.

[0127] As shown in Figures 11 to 14, the electronic atomization device also includes a bracket 20a, which is arranged between the battery cell 16a and the liquid storage chamber 12a to accommodate and support the first liquid-conducting element 50a and the tubular element 14a. The bracket 20a includes a first support portion 210a, a second support portion 220a, and a third support portion 230a, which are arranged in sequence along the longitudinal direction.

[0128] The first support portion 210a defines a first accommodating cavity 240a for accommodating and installing the first liquid-conducting element 50a. The first accommodating cavity 240a is open at the upper end of the bracket 20a, and the first liquid-conducting element 50a is installed into the first accommodating cavity 240a through the upper opening.

[0129] A second accommodating cavity 250a is defined in the second supporting portion 220a for at least partially mounting and accommodating the tubular element 14a and the atomizing assembly;

[0130] The third supporting portion 230a is connected to the housing 10a by means of riveting, snapping or other fastening methods.

[0131] In this embodiment, a plurality of flanges 221a circumferentially surrounding the bracket 20a and grooves 222a defined between adjacent flanges 221a are arranged on the outer surface of the second support portion 220a; in this embodiment, most of the flanges 221a are basically against the inner surface of the outer shell 10a or close to the inner surface of the outer shell 10a.

[0132] As shown in Figures 12 to 14 , the second accommodating cavity 250a of the stent 20a has an increased inner diameter section 254a proximal to the first accommodating cavity 240a. The inner diameter of this increased inner diameter section 254a increases as it approaches the first accommodating cavity 240a. The inner surface of this increased inner diameter section 254a is inclined. After assembly, the through-hole 142a of the tubular element 14a is opposite the increased inner diameter section 254a. In some examples, at least a portion of the through-hole 142a of the tubular element 14a is offset from the first liquid-conducting element 50a, thereby ensuring that a portion of the through-hole 142a of the tubular element 14a is not covered or obscured by the inner surface of the first liquid-conducting element 50a.

[0133] As shown in Figure 12 , after assembly, the increased inner diameter section 254a defines a liquid buffer space 255a surrounding the through-hole 142a. This liquid buffer space 255a is in fluid communication with the second surface 520a of the first liquid-conducting element 50a. During use, liquid matrix within the liquid reservoir 12a is drawn through the first surface 510a of the first liquid-conducting element 50a, then flows out through the second surface 520a into the liquid buffer space 255a defined by the increased inner diameter section 254a. Ultimately, it passes through the through-hole 142a of the tubular element 14a and is drawn into the second liquid-conducting element 30a, as indicated by arrows R1 in Figures 11 and 12 .

[0134] 12 , the first liquid-conducting 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 liquid-conducting element 30a is surrounded by the first liquid-conducting element 50a, or a portion of the second liquid-conducting element 30a extends into the first liquid-conducting element 50a.

[0135] As shown in FIG. 13 and FIG. 14 , the bracket 20 a further defines an air inlet channel, which provides an air flow path for air to enter the second accommodating cavity 250 a . The air inlet channel includes:

[0136] The first channel portion 23a passes through the third support portion 230a to the groove 222a on the outer surface of the second support portion 220a;

[0137] The second channel portion 25a extends from the groove 222a to the second accommodating chamber 250a. During inhalation, air passes through the first channel portion 23a, through the third support portion 230a, and into the groove 222a. It is then delivered circumferentially through the groove 222a to the second channel portion 25a, then through the atomizer assembly and delivered to the air outlet 113a through the aerosol output tube 11a.

[0138] The first communication opening between the first channel portion 23a and the groove 222a and the second communication opening between the second channel portion 25a and the groove 222a are circumferentially staggered. Furthermore, the first communication opening between the first channel portion 23a and the groove 222a and the second communication opening between the second channel portion 25a and the groove 222a are circumferentially opposite to each other. Furthermore, the first communication opening between the first channel portion 23a and the groove 222a is at a different longitudinal height than the second communication opening between the second channel portion 25a and the groove 222a. Specifically, the first communication opening between the first channel portion 23a and the groove 222a is closer to the liquid storage chamber 12a than the second communication opening between the second channel portion 25a and the groove 222a.

[0139] As shown in Figures 13 and 14 , the support 20a further defines a ventilation channel to provide a path for air to enter the liquid storage chamber 12a. When the negative pressure in the liquid storage chamber 12a exceeds a predetermined threshold, air enters the liquid storage chamber 12a through the ventilation channel to relieve the negative pressure in the liquid storage chamber 12a. The ventilation channel includes:

[0140] The vent hole 261a extends longitudinally from the lower surface of the first support portion 210a to the inner bottom wall of the first accommodating cavity 240a;

[0141] The vent groove 262a extends longitudinally along the inner surface of the first accommodating chamber 240a. When the first liquid-conducting element 50a is accommodated or retained within the first accommodating chamber 240a, the vent groove 262a defines a gap or space between the inner surface of the first accommodating chamber 240a and the outer surface 530a of the first liquid-conducting element 50a. Air enters the first accommodating chamber 240a through the vent hole 261a and then flows through the vent groove 262a into the liquid storage chamber 12a, as indicated by arrow R3 in Figures 11 to 14.

[0142] As shown in FIG. 11 to FIG. 14 , the air inlet end of the vent hole 261 a is communicated with the groove 222 a of the second support portion 220 a , thereby providing air outside the second support portion 220 a to enter the ventilation channel.

[0143] As shown in Figures 11 to 14 , an annular lip 256a is further disposed within the second accommodating cavity 250a of the bracket 20a. This lip 256a defines a clamping gap with the inner surface of the second accommodating cavity 250a for clamping or retaining the tubular element 14a. During assembly, the tubular element 14a is inserted between the lip 256a and the inner surface of the second accommodating cavity 250a. In Figures 11 and 12 , the lip 256a longitudinally abuts and supports the second liquid-conducting element 30a, thereby at least partially supporting the second liquid-conducting element 30a.

[0144] As shown in Figures 11 to 14 , the third support portion 230a of the bracket 20a further defines a third cavity 235a. After assembly, the electrical contact 2130a at least partially extends into the third cavity 235a. The conductive lead of the heating element 40a contacts or is welded to the electrical contact 2130a within the third cavity 235a, forming an electrically conductive connection. Furthermore, as shown in Figures 11 to 14 , the third support portion 230a is connected to the contact base 2131a surrounding the electrical contact 2130a.

[0145] It should be noted that the specification and drawings of this application provide preferred embodiments of the present application, but are not limited to the embodiments described in this specification. Furthermore, it is possible for a person skilled in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
