[0002] This utility model belongs to the field of electronic atomization technology, and specifically relates to an atomizer and electronic atomization device. Background Technology

[0003] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

For example, the material could be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, aerosol-providing articles exist, such as so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize, thereby producing an inhalable aerosol. Known electronic atomizing devices surround and support the atomizing assembly by a bracket; and ventilation channels are arranged on the bracket to provide a path for air to enter the reservoir when the negative pressure in the reservoir exceeds a predetermined threshold, thereby alleviating the negative pressure in the reservoir.

[0071] This utility model will be further described in detail below with reference to the accompanying drawings:

[0072] One embodiment of this application discloses an electronic atomizing device; please refer to [link / reference]. Figure 1 As shown, it includes an atomizer 1 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply mechanism 2 that supplies power to the atomizer 1.

[0073] In an alternative implementation, for example Figure 1 As shown, the power supply mechanism 2 includes a receiving cavity 21 disposed at one end along the length direction for receiving and accommodating at least a portion of the atomizer 1, and a second electrical contact 22 at least partially exposed within the receiving cavity 21 for forming an electrical connection with the atomizer 1 when at least a portion of the atomizer 1 is received and accommodated within the power supply mechanism 2, thereby supplying power to the atomizer 1.

[0074] according to Figure 1 In the preferred embodiment shown, a first electrical contact 121 is provided on the end of the atomizer 1 opposite to the power supply mechanism 2 along the length direction. When at least a portion of the atomizer 1 is received in the receiving cavity 21, the first electrical contact 121 becomes conductive by contacting and abutting against the second electrical contact 22.

[0075] A sealing element 23 is provided inside the power supply mechanism 2, and the sealing element 23 divides at least a portion of the internal space of the power supply mechanism 2 to form a receiving cavity 21. Figure 1 In the preferred embodiment shown, the seal 23 is configured to extend in a longitudinal direction perpendicular to the power supply mechanism 2, and is preferably made of a flexible material such as silicone, thereby preventing the liquid matrix that seeps from the atomizer 1 into the receiving chamber 21 from flowing into components such as the controller 24 and sensor 25 inside the power supply mechanism 2.

[0076] exist Figure 1 In the preferred embodiment shown, the power supply mechanism 2 further includes a battery cell 26 for power supply located at the other end of the receiving cavity 21 along the length direction; and a controller 24 disposed between the battery cell 26 and the receiving cavity 21, the controller 24 being operable to guide current between the battery cell 26 and the second electrical contact 22.

[0077] In use, the power supply mechanism 2 includes a sensor 25 for sensing the suction airflow generated when the atomizer 1 is inhaled, and then the controller 24 controls the battery cell 26 to supply power to the atomizer 1 according to the detection signal of the sensor 25.

[0078] Further in Figure 1 In the preferred embodiment shown, the power supply mechanism 2 is provided with a charging interface 27 at the other end away from the receiving cavity 21 for charging the battery cell 26.

[0079] Figures 2 to 4 The embodiments are shown Figure 1 A schematic diagram of one embodiment of the atomizer 1 is shown. The atomizer 1 includes a housing 11, which is generally hollow cylindrical and contains necessary functional components for storing and atomizing a liquid matrix. The housing 11 has a proximal end 110 and a distal end 111 that are opposite to each other in the longitudinal direction. The proximal end 110 is configured for the user to inhale the aerosol, and has an outlet 112 for the user to inhale. The distal end 111 is connected to a power supply mechanism 2, and is open, with a removable end cap 12 mounted thereon. The open structure allows for the installation of various functional components inside the housing 11. After assembly, the housing 11 and the end cap 12 together define the outer surface of the atomizer 1.

[0080] according to Figures 2 to 4 As shown, the first electrical contact 121 extends from the surface of the end cap 12 into the interior of the atomizer 1, thus at least partially exposed outside the atomizer 1. When at least a portion of the atomizer 1 is received within the receiving cavity 21, it contacts and abuts against the second electrical contact 22, thereby establishing conductivity. Simultaneously, the end cap 12 is also provided with an air inlet 122 for allowing external air to enter the atomizer 1 during inhalation. After assembly, the first electrical contact 121 is flush with the surface of the end cap 12.

[0081] Please see Figures 2 to 16 As shown, the outer casing 11 contains:

[0082] Storage chamber 113 for storing liquid matrix;

[0083] An air tube 114 and a support 13 are arranged sequentially along the longitudinal direction of the atomizer 1; the air tube 114 and the support 13 are at least partially inside the liquid storage chamber 113, and the liquid storage chamber 113 is defined by the air tube 114 and the support 13 and the inner surface of the outer shell 11. In an embodiment, the side of the liquid storage chamber 113 near the proximal end 110 is closed by the outer shell 11, and the side near the distal end 111 is open.

[0084] according to Figures 2 to 16 As shown, the outer casing 11 also contains:

[0085] A flexible base 14 is at least partially located between the housing 11 and the support 13, providing a seal between them. The base 14 at least partially surrounds or encloses the support 13; and the base 14 closes the opening of the reservoir 113 toward the distal end 111 to prevent leakage of the liquid matrix from the opening of the reservoir 113; the base 14 may be made of an elastic material such as silicone, rubber or thermoplastic elastomer to improve the sealing effect.

[0086] Please see Figures 2 to 16As shown, the support 13 extends longitudinally along the atomizer 1 and has a first portion 133 and a second portion 134 arranged sequentially along the longitudinal direction. The first portion 133 and / or the second portion 134 are hollow annular. In an embodiment, the outer diameter of the first portion 133 near the proximal end 110 is smaller than the outer diameter of the second portion 134 near the distal end 111. A portion of the liquid reservoir 113 is defined between the second portion 134 and the outer shell 11.

[0087] Please see Figure 4 and Figure 5 As shown, the first part 133 has an endotracheal inlet 1331, the inner diameter of which is adapted to the outer diameter of the end of the endotracheal tube 114 near the distal end 111, so that at least a portion of the endotracheal tube 114 is fitted into the endotracheal inlet 1331. A sealing element 115 is also arranged between the endotracheal tube 114 and the first part 133 of the support 13 to provide a seal between the endotracheal tube 114 and the endotracheal inlet 1331.

[0088] according to Figures 2 to 16 As shown, at least a portion of the second part 134 is inserted into the base 14 and held by the base 14. An inner support wall 1341 is arranged within the second part 134, extending axially within the second part 134; the length of the inner support wall 1341 is less than the length of the second part 134.

[0089] according to Figures 2 to 16 As shown, the atomizer 1 also includes a tubular element 15. The tubular element 15 is axially held between the inner support wall 1341 of the second portion 134 of the support 13 and the base 14. The tubular element 15 is rigid, for example, made of a rigid material such as ceramic, metal, or alloy. Multiple perforations 151 are arranged on the wall of the tubular element 15.

[0090] according to Figures 2 to 16 As shown, a step is defined on the inner support wall 1341 of the second part 134 of the bracket 13; during assembly, the upper end of the tubular element 15 is inserted into the inner support wall 1341 and abuts against the step of the inner support wall 1341 to form a fastened assembly. Furthermore, the tubular element 15 and the inner support wall 1341 are connected by a tight fit or interference fit. Figures 2 to 16 As shown, the base 14 is also provided with a first receiving groove 144 for inserting the lower end of the tubular element 15 into the base 14; at least a portion of the lower end of the tubular element 15 is inserted into the first receiving groove 144 of the base 14 so that the tubular element 15 is securely held between the support 13 and the base 14.

[0091] Please see Figures 9 to 11As shown, the tubular element 15 is provided with a plurality of perforations 151 for the flow of liquid matrix. The plurality of perforations 151 are arranged at intervals along the circumference of the tubular element 15 and can be arranged in one or more layers along the longitudinal direction of the tubular element 15. In some embodiments, the perforations 151 are elongated shapes extending along the axial direction of the tubular element 15; or, the perforations 151 are in the form of waist-shaped holes; or, the perforations 151 can be configured as follows Figure 9 The shape shown is an oval; or as shown in the image. Figure 10 The T-shape shown, or as... Figure 11 The perforation 151 shown is a shape with an increased width in the middle section. The width of the perforation 151 is approximately between 0.3 mm and 1.5 mm. By setting multiple capillary-width perforations 151 on the tubular element 15, the liquid flow rate of the liquid matrix can be precisely controlled, effectively solving the problems of excessively fast liquid matrix supply and excessively large flue gas particles during operation.

[0092] according to Figures 2 to 16 As shown, the atomizer 1 further includes an atomizing assembly for atomizing a liquid matrix to generate an aerosol. The atomizing assembly and the tubular element 15 are at least partially located within a second portion 134 of the support 13, and are thus at least partially supported and held by the support 13. The atomizing assembly includes:

[0093] Liquid guiding element 17 is used to draw liquid matrix from liquid storage chamber 113;

[0094] Heating element 18 is combined with liquid guiding element 17 and is used to heat at least a portion of the liquid matrix within liquid guiding element 17 to generate an aerosol.

[0095] In some embodiments, the fluid guiding element 17 is flexible, for example, made of flexible fibers such as cotton fibers, nonwoven fabric, or sponge. The fluid guiding element 17 is configured as a tubular or cylindrical shape arranged along the longitudinal direction of the housing 11; the fluid guiding element 17 is coaxial with and located within the tubular element 15. Specifically, for example, the fluid guiding element 17 is a cylindrical shape wound from a sheet-like precursor comprising multiple layers of flexible fibers. Alternatively, in some other variations, the fluid guiding element 17 is rigid; for example, the fluid guiding element 17 may comprise a rigid porous element, such as porous ceramic or porous glass.

[0096] In one embodiment, the liquid guiding element 17 receives the liquid matrix through the perforation 151. In another embodiment, the outer surface of the liquid guiding element 17 in the radial direction is configured as an absorbent surface for absorbing the liquid matrix; specifically, a portion of the outer surface of the liquid guiding element 17 covers or aligns with the perforation 151, thereby receiving and absorbing the liquid matrix passing through the perforation 151, such as... Figure 4As indicated by the middle arrow R1, the inner surface of the liquid guiding element 17 in the radial direction is configured as an atomizing surface, which is combined / attached / abutted to the heating element 18; then, after the liquid matrix is ​​transferred to the atomizing surface, it is heated and atomized by the heating element 18 to generate an aerosol and released.

[0097] according to Figures 3 to 9 As shown, in this embodiment, the heating element 18 is arranged to extend longitudinally along the liquid guiding element 17, and the heating element 18 is coaxially arranged with the liquid guiding element 17. In some alternative embodiments, the heating element 18 is a heating mesh, heating coil, etc. In this embodiment, the heating element 18 is a heating element wound from a sheet-like or mesh-like substrate; the wound heating element 18 is not a closed tube in the circumferential direction, but a cylindrical shape with side openings in the longitudinal direction. Conductive leads 181 are welded or arranged at both ends of the heating element 18 for guiding current in the heating element 18.

[0098] In some variations, the heating element 18 may be attached to the liquid guiding element 17 by means of printing, deposition, sintering, or physical assembly. In some other variations, the liquid guiding element 17 may have a planar or curved surface for supporting the heating element 18, which is formed on the planar or curved surface of the liquid guiding element 17 by means of mounting, printing, deposition, etc. Alternatively, in some variations, the heating element 18 is a conductive trace formed on the surface of the liquid guiding element 17. In some variations, the conductive trace of the heating element 18 may be in the form of printed lines formed by printing. In some variations, the heating element 18 is a patterned conductive trace. In some variations, the heating element 18 is planar. In some variations, the heating element 18 is a tortuous, meandering, reciprocating, or zigzag extended conductive trace.

[0099] according to Figures 2 to 16 As shown, the atomizer 1 further includes a lead wire isolation element 19. The lead wire isolation element 19 is at least partially inserted into the tubular element 15 from its lower end; the lead wire isolation element 19 is annular in shape; in one aspect, the lead wire isolation element 19 is provided with two circumferentially isolated lead wire grooves 191, and during assembly, the two conductive leads 181 connected to both ends of the heating element 18 are respectively accommodated in the two lead wire grooves 191 and thus separated and fixed to prevent short circuits caused by bending or other contact conduction of the two conductive leads 181 during assembly. In another aspect, the liquid guiding element 17 abuts against the lead wire isolation element 19 to form a stop. In an embodiment, a portion of the lead wire isolation element 19 is accommodated within a first receiving groove 144 of the base 14.

[0100] Please see Figures 3 to 15As shown, the atomizer 1 further includes at least one capillary element, such as capillary element 16, for transferring the liquid matrix between the reservoir 113 and the liquid guiding element 17. The at least one capillary element 16 is located between the second portion 134 of the support 13 and the tubular element 15, and is arranged around or surrounding the tubular element 15. The at least one capillary element 16 is used to receive the liquid matrix from the reservoir 113 and adsorb and retain the received liquid matrix through internal capillary structures or capillary pores, etc. Of course, the at least one capillary element surrounds the tubular element 15 and covers the perforations 151. In use, the liquid matrix in the reservoir 113 is first transferred to the at least one capillary element 16 for absorption and retention, and then the liquid guiding element 17 indirectly draws the liquid matrix originating from the reservoir 113 from the at least one capillary element 16, for example... Figures 4 to 15 As indicated by the middle arrow R1.

[0101] In some embodiments, at least one capillary element 16 is made of a flexible capillary fiber material, such as natural cotton fibers, nonwoven fibers, etc. Alternatively, in other embodiments, at least one capillary element 16 comprises rayon, or rigid rayon or artificial foam made of filamentous polyurethane. For example, the capillary element 16 uses 138# rigid synthetic organic polymer fiber with a strength of 0.1–0.9 mg / mm². 3 The density. Specifically, for example, capillary element 16 is rigid rayon comprising oriented polyester fibers, or rigid rayon or artificial foam made of filamentous polyurethane. Or in some other embodiments, at least one capillary element 16 may also comprise a rigid porous element such as a porous ceramic body, porous glass, etc., which forms capillary channels through micropores within them to adsorb and retain the liquid matrix.

[0102] exist Figures 3 to 15 In the illustrated embodiment, the capillary element 16 is arranged in an annular shape. One or more liquid guiding holes 131 are arranged on the second portion 134 of the support 13, surrounding the capillary element 16. Furthermore, the outer surface of the capillary element 16 is in fluid communication with the reservoir 113 through the liquid guiding holes 131, thereby receiving the liquid matrix passing through the reservoir 113; the inner surface of the capillary element 16 surrounds the tubular element 15 and covers the perforations 151, thereby allowing the liquid guiding element 17 to indirectly draw the liquid matrix originating from the reservoir 113 from the capillary element 16; as Figures 4 to 15 As indicated by the middle arrow R1.

[0103] Please see Figures 3 to 4As shown, the capillary element 16 is flexible; after assembly, the flexible capillary element 16 is radially squeezed or compressed from the inner and outer sides by the second part 134 of the support 13 and the tubular element 15, respectively, thereby stably restricting and holding the capillary element 16 between the second part 134 of the support 13 and the tubular element 15, which is advantageous for enhancing the fluid retention of at least one capillary element, such as the capillary element 16.

[0104] according to Figures 3 to 15 As shown, after assembly, the upper surface of the capillary element 16 axially abuts against the inner support wall 1341.

[0105] according to Figures 3 to 15 As shown, in the embodiment, the bracket 13 defines the following:

[0106] The first gap space 135 is formed or defined in the axial direction between the upper surface of the capillary element 16 and the support 13; specifically, the inner support wall 1341 and the second part 134 of the support 13 are arranged at intervals in the radial direction; thus, when the upper surface of the capillary element 16 axially abuts against the inner support wall 1341, the upper surface of the capillary element 16 closes the gap between the inner support wall 1341 and the second part 134 of the support 13, thereby forming the first gap space 135.

[0107] In this embodiment, a second spacer space 136 is further defined within the support 13, formed or defined axially between the lower surface of the capillary element 16 and the lower end / base 14 of the second portion 134; thereby preventing the lower surface of the capillary element 16 from contacting the base 14. This prevents the liquid matrix adsorbed and held within the capillary element 16 from seeping into the surface of the base 14 through contact.

[0108] according to Figures 4 to 16 As shown, the inner surface of the second portion 134 of the support 13 is also provided with one or more air communication slots 1343 extending longitudinally; the air communication slots 1343 are substantially longitudinally across the capillary element 16; and thus, after assembly, the first space 135 and the second space 136 are connected by airflow through the air communication slots 1343.

[0109] In some embodiments, the atomizer 1 further includes an airflow channel for providing an airflow path from the air inlet 122 through the atomizing assembly to the air outlet 112 during inhalation, thereby delivering the aerosol to the air outlet 112. In embodiments, the complete airflow channel is defined by multiple components.

[0110] Specifically according to Figures 4 to 15As indicated by the middle arrow R2, the complete airflow path during suction includes: air entering from the air inlet 122 passes through the base 14 and the lead wire isolation element 19 to the atomizing assembly / heating element 18, and carries the aerosol generated by the heating element 18 out of the air tube 114 to the air outlet 112 for inhalation by the user. Figures 2 to 9 As shown, there is a gap between the assembled rear end cover 12 and the base 14, and the gap between them forms or defines a condensate storage cavity for storing aerosol condensate flowing out of the base 14 from the airflow channel, or for preventing aerosol condensate in the airflow channel from flowing directly from the base 14 to the air inlet 122. According to Figure 4 and Figure 15 As shown, after assembly, the air tube 114 and the tubular element 15 / liquid guiding element 17 are arranged at intervals, and the support 13 assembles them to form an airflow communication.

[0111] In some embodiments, the atomizer 1 further includes a ventilation channel for providing a path for air to enter the liquid reservoir 113 when the negative pressure within the liquid reservoir 113 exceeds a predetermined threshold. Specifically, according to Figure 4 , Figure 15 and Figure 16 As shown, the ventilation channel includes:

[0112] A first ventilation groove 132 is formed on the outer surface of the second portion 134 of the support 13 and extends from the lower end of the second portion 134 into the reservoir 113. A portion of the first ventilation groove 132 is surrounded and covered from the outside by the base 14; and a portion of the first ventilation groove 132 extends out of the base 14 and is exposed outside the base 14. The first ventilation groove 132 is in fluid communication with the reservoir 113 through the portion exposed outside the base 14. The first ventilation groove 132 provides a channel path connecting the reservoir 113 with the second spacer space 136.

[0113] according to Figure 4 , Figure 15 and Figure 16 As shown, the ventilation channel also includes:

[0114] The second ventilation groove 1342 is formed or defined on the inner surface of the inner support wall 1341 of the bracket 13 and extends axially along the inner support wall 1341; and the extension length of the second ventilation groove 1342 is greater than the length of the tubular element 15 inserted into the inner support wall 1341; therefore, after assembly, a portion of the second ventilation groove 1342 is closer to the first portion 133 of the bracket 13 than the tubular element 15, and is not covered by the tubular element 15; a portion of the second ventilation groove 1342 is covered by the tubular element 15. The portion of the second ventilation groove 1342 that is offset from the tubular element 15 communicates with the airflow channel. The second ventilation groove 1342 has a notch defined at the end of the inner support wall 1341 that abuts against the upper surface of the capillary element 16, so that in use, the first gap space 135 is communicated with the airflow channel by the second ventilation groove 1342. Alternatively, this portion of the ventilation channel defined by the second ventilation groove 1342 is formed or defined between the tubular element 15 and the inner support wall 1341 of the support 13. This allows the ventilation channel to flow through the upper surface of the capillary element 16.

[0115] In this embodiment, the ventilation channel is connected to the airflow channel, allowing air from the airflow channel to enter the liquid storage chamber 113 via the ventilation channel, thereby relieving pressure within the liquid storage chamber 113. For a detailed and complete ventilation path, please refer to [link to full description]. Figures 4 to 15 As shown, the following are included in sequence:

[0116] When the negative pressure in the liquid storage chamber 113 exceeds a predetermined threshold, air is drawn from the airflow channel through the second ventilation slot 1342 into the first space 135, such as... Figure 4 and Figure 16 As indicated by the middle arrow R31;

[0117] The air in the first partition space 135 then flows to the second partition space 136 via the air communication channel 1343, such as Figure 16 As indicated by the middle arrow R32;

[0118] The air in the second partition space 136 then enters the liquid storage chamber 113 through the first ventilation groove 132, such as Figure 15 and Figure 16 As indicated by the middle arrow R33, this is to alleviate the negative pressure in the liquid storage chamber 113.

[0119] In some embodiments, an annular groove 1431 is arranged on the surface of the base 14 facing the support 13, the annular groove 1431 surrounding the tubular element 15; and the annular groove 1431 is spaced from the lower end of the second portion 134 of the support 13. Subsequently, after assembly, the annular groove 1431 at least partially defines a liquid collection space 141 adjacent to or in communication with the first ventilation channel 132; the liquid collection space 141 is used to store the liquid matrix that seeps out through the first ventilation channel 132.

[0120] During use, when the pressure inside the liquid storage chamber 113 is greater than the external pressure, the liquid matrix inside the liquid storage chamber 113 can seep into the liquid collection space 141 through the first ventilation groove 132, and be adsorbed and retained in the liquid collection space 141; and when the pressure inside the liquid storage chamber 113 is less than the external pressure, for example during air transport or product testing, the liquid matrix that has seeped into the liquid collection space 141 flows back into the liquid storage chamber 113 through the wetting of the first ventilation groove 132. The first ventilation groove 132 has a depth or width of approximately 0.5 to 3.0 mm.

[0121] In some specific embodiments, the first ventilation groove 132 is constructed as a plurality of capillary grooves arranged at intervals along the circumference of the support 13, with a width between 0.2 mm and 2 mm. Under the action of negative pressure, the liquid matrix buffered in the liquid collection space 141 can be adsorbed and flowed back into the liquid storage chamber 113 by capillary force, so that the liquid matrix buffered in the liquid collection space 141 can be reused.

[0122] Please see Figure 4 , Figure 7 As shown, the base 14 includes a sidewall 142 surrounding at least a portion of the support 13. At least a portion of the first ventilation groove 132 is exposed on the sidewall 142, thereby enabling the first ventilation groove 132 to communicate with the liquid storage chamber 113, allowing external air to enter the liquid storage chamber 113 through the ventilation channel. Similarly, the liquid guide hole 131 is exposed on the sidewall 142, thereby enabling the liquid guide hole 131 to communicate with the liquid storage chamber 113, allowing the liquid matrix in the liquid storage chamber 113 to flow through.

[0123] The base 14 accommodates at least a portion of the support 13 near its distal end 111, and the base 14 and the bottom of the support 13 cooperate to define a liquid collection space 141 for buffering the liquid matrix. At least a portion of a ventilation channel is also defined between the support 13 and the base 14 to provide a flow path for air to enter the liquid storage chamber 113. When the negative pressure in the liquid storage chamber 113 exceeds a threshold, external air can enter the liquid storage chamber 113 through the ventilation channel to alleviate the negative pressure. Based on this, at least a portion of the ventilation channel fluidly connects the liquid storage chamber 113 and the liquid collection space 141, allowing the liquid collection space 141 to buffer the liquid matrix seeping out from the ventilation channel to prevent contamination from liquid matrix outflow. Under negative pressure, the liquid matrix buffered in the liquid collection space 141 can also flow back into the liquid storage chamber 113 through the ventilation channel, allowing the liquid matrix to be reused and improving its utilization rate.

[0124] For further information, please refer to [link / reference]. Figure 8As shown, the base 14 also includes a base 143 for supporting the bottom of the support 13 upwards. The liquid collection space 141 includes an annular groove 1431 formed on the base 143 and arranged around the base 143 in a circumferential manner. The annular groove 1431 is located below the bottom of the first ventilation groove 132 and is used to collect the liquid matrix flowing out of the first ventilation groove 132.

[0125] For details, please refer to Figure 4 , Figure 7 , Figure 8 As shown, at least a portion of the second part 134 is housed within the base 14, and a liquid collection space 141 for buffering the liquid matrix is ​​defined between the bottom of the second part 134 and the base 14. The sidewall 142 of the base 14 surrounds the outside of at least a portion of the second part 134, and a liquid guide hole 131 arranged on the second part 134 is exposed on the sidewall 142 so that the liquid guide hole 131 communicates with the liquid storage chamber 113. One end of the first ventilation groove 132 arranged on the second part 134 is exposed on the sidewall 142 to communicate with the liquid storage chamber 113, and the other end communicates with the liquid collection space 141, thereby forming part of the ventilation channel to balance the air pressure in the liquid storage chamber 113, and also to allow the liquid matrix buffered in the liquid collection space 141 to flow back and be reused through the ventilation groove.

[0126] according to Figure 16 As shown, the first portion 133 of the support 13 also has an abutment portion 137; after assembly, the air tube 114 and / or sealing element 115 extend into the first portion 133 of the support 13 and abut against the abutment portion 137. In an embodiment, the abutment portion 137 is provided with a plurality of serrated protrusions 1372, and capillary gaps are formed between the plurality of protrusions 1372 to absorb aerosol condensate in the airflow channel, especially aerosol condensate falling from the air tube 114.

[0127] A condensate guiding structure 1371 extending into the air pipe 114 is also arranged on the contact part 137; the condensate guiding structure 1371 is in Figure 16 The condensate guiding structure 1371 is arranged in the form of convex ridges. After assembly, the condensate guiding structure 1371 extends at least partially into the air tube 114. It can directly abut against the inner surface of the air tube 114, or it can not contact the inner surface of the air tube 114 but form a capillary gap with the air tube 114. In this way, the aerosol condensate in the air tube 114 is guided into the capillary gap between the convex teeth 1372 and kept there by contact or capillary adsorption. This is beneficial for preventing the aerosol condensate from being drawn in by the user.

[0128] The above are merely preferred embodiments of the present utility model and do not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
