In some embodiments, the connecting portion 182 may be columnar, and the columnar shape may be a prism or a cylinder. In some embodiments, the connecting portion 182 may be an irregular shape, which is not described in detail. The end of the connecting portion 182 facing the atomizer core 17 is at least partially inserted into the accommodating cavity 160 of the sleeve 16, and is interference-fitted with the sleeve 16 to achieve the connection between the bottom seal 18 and the sleeve 16. The shape of the end of the connecting portion 182 facing the atomizer core 17 is adapted to the shape of the accommodating cavity 160 to play a sealing and leak-proof role. Regarding the shape of the connection portion 182, those skilled in the art can adjust it according to the shape of the accommodating chamber 160, which will not be described in detail here. In some embodiments, at least two pin holes 1820 are provided at one end of the connection portion 182 facing the atomizer core 17. In some embodiments, a through airway hole 1821 is provided at one end of the connection portion 182 facing the atomizer core 17. In some embodiments, a groove 1822 is provided at one end of the connection portion 182 away from the pin hole 1820 / atomizer core 17. In some embodiments, a plurality of convex ridges 183 are provided on the side wall of the connection portion 182.

[0054] The side wall of the connection part 182 is provided with a plurality of convex ridges 183, so that the connection part 182 and the sleeve 16 are easy to assemble, and the leakage-proof effect of the bottom seal 18 is continuous and stable. Due to the use of a structure with multiple convex ridges 183, the contact area between the convex ridges 183 and the sleeve 16 is small, and the friction resistance is small. Due to the use of a structure with multiple convex ridges 183, the elastic compression space of the bottom seal 18 is greatly increased, and the relative force between the bottom seal 18 and the sleeve 16 is small. The bottom seal 18 with a structure with multiple convex ridges 183 has a small relative force with the sleeve 16, and the friction resistance is small, which can greatly reduce the wear of the bottom seal 18 caused by repeated plugging and unplugging. The bottom seal 18 with a structure with multiple convex ridges 183 has a large elastic compression space, and the relative force with the sleeve 16 is small, which greatly prolongs the elastic fatigue time of the bottom seal 18, and can achieve a long-term continuous and stable sealing and leakage-proof effect. The relative force between the bottom seal 18 and the sleeve 16 of the multiple convex ridges 183 structure is small, so the interference fit can be appropriately increased. Due to the large interference fit, the impact of the size change of the bottom seal 18 caused by the temperature difference can be greatly buffered, thereby greatly reducing the risk of sealing failure in an environment with a large temperature difference.

[0055] In some embodiments, the pin hole 1820 is opened at one end of the connecting portion 182 toward the atomizer core 17. The pin hole 1820 extends in a direction away from the atomizer core 17. In some embodiments, there are two pin holes 1820. In some embodiments, there are three pin holes 1820. In some embodiments, there are multiple pin holes 1820, and multiple refers to two or more. The number of pin holes 1820 is the same as the number of pins of the heating element 172, so that the pins of the heating element 172 are respectively electrically connected to the power supply assembly 20 after penetrating different pin holes 1820. The pins of the heating element 172 at least partially penetrate the pin holes 1820. Regarding the number of pin holes 1820, those skilled in the art can adjust it according to the pins of the heating element 172, which will not be described in detail here. In some embodiments, the airway hole 1821 is eccentrically arranged on one side of the bottom seal 18 relative to the central axis of the bottom seal 18, so that the other side of the bottom seal 18 forms an area with a certain thickness, which can be used as the opening position of the pin hole 1820. Exemplarily, the airway hole 1821 is eccentrically arranged on one side of the bottom seal 18, and at least two pin holes 1820 are distributed on the other side of the bottom seal 18. For example, all pin holes 1820 can be distributed on the other side of the bottom seal 18, that is, each pin hole 1820 is located on the same side of the airway hole 1821. Since the pin hole 1820 is arranged at a thicker portion of the seal 18, the side wall between the pin hole 1820 and the airway hole 1821 can have a sufficient thickness in a direction perpendicular to the central axis A3 of the airway hole 1821. The increased thickness of the side wall enhances its strength, thereby preventing the side wall from deforming after the pin is inserted into the pin hole 1820, causing the airway hole 1821 to deform. Specifically, the airway hole 1821 is eccentrically arranged on one side of the connecting portion 182 relative to the central axis A4 of the connecting portion 182, and at least two pin holes 1820 are distributed on the other side of the connecting portion 182. In some embodiments, the central axis A4 of the connecting portion 182 and the central axis A1 of the atomizing chamber 1710 are on the same extension line, so that the cooperation between the connecting portion 182 and the sleeve 16 is more stable and reliable.

[0056] Optionally, the central axis of the atomizing chamber 1710 is not colinear with the central axis of the airway hole 1821, so that the airflow channels of the atomizing chamber 1710 and the airway hole 1821 are staggered, and such a setting can also facilitate the pins of the heating element 172 to extend downward to the pin hole 1820, which is convenient for aligning the pins of the heating element 172 with the pin hole 1820 during assembly. In some embodiments, the central axis A2 of the pin hole 1820 is substantially parallel to the central axis A3 of the airway hole 1821.

[0057] In some embodiments, the pin hole 1820 may be a circular hole. In some embodiments, the pin hole 1820 may be an elliptical hole. In some embodiments, the pin hole 1820 may be other irregular shapes, such as a hole with a prismatic cross section. In some embodiments, the pin hole 1820 may be other irregular shapes, which will not be described in detail. In some embodiments, the opening of the pin hole 1820 toward the atomizer core 17 is horn-shaped, which is convenient for alignment and positioning when the pins are assembled. In some embodiments, a plurality of pin holes 1820 are arranged around the same side of the airway hole 1821. The pin hole 1820 is arranged around the same side of the airway hole 1821, so that the position space occupied by the pin hole 1820 is less, and the side wall between the pin hole 1820 and the airway hole 1821 is made thicker in the direction perpendicular to the central axis A3 of the airway hole 1821. In some embodiments, the pin hole 1820 is a blind hole, and the pin of the heating element 172 at least partially penetrates the bottom wall 18201 of the blind hole, extends in the direction away from the atomizer core 17, and is electrically connected to the power supply assembly 20 respectively. The blind hole makes the sealing effect better and ensures that the atomized matrix does not leak. The bottom wall 18201 of the blind hole plays a certain supporting role, so that when the pin penetrates the bottom wall 18201 of the blind hole, the side wall of the pin hole 1820 does not deform, thereby ensuring that the side wall connecting the pin hole 1820 and the airway hole 1821 does not deform, and ensuring that the airway hole 1821 does not deform, thereby ensuring the stability of the suction resistance and the consistency of the taste. In some embodiments, the pin hole 1820 is a through hole, and the pin of the heating element 172 at least partially penetrates the through hole, extending in a direction away from the atomization core 17, and is electrically connected to the power supply assembly 20 respectively.

[0058] In some embodiments, the airway hole 1821 is opened at one end of the connecting portion 182 toward the atomizing core 17, and the airway hole 1821 extends in a direction away from the atomizing core 17, and the airway hole 1821 runs through the base 181 and the connecting portion 182. External air can enter the atomizing chamber 1710 from the airway hole 1821, and mix with the aerosol in the atomizing chamber 1710 and discharge the mouthpiece together. In some embodiments, the central axis A3 of the airway hole 1821 is substantially parallel to the central axis A2 of the pin hole 1820. In some embodiments, the airway hole 1821 is a cylindrical through hole, that is, the cross section of the airway hole 1821 is circular. In some embodiments, the airway hole 1821 is a through hole with an elliptical cross section. In some embodiments, the airway hole 1821 is a through hole with a prismatic cross section. In some embodiments, the airway hole 1821 can be other shapes, such as an irregular shape.

[0059] The pin hole 1820 is on the same side of the airway hole 1821. The same side is determined according to the cross-sectional shape of the airway hole 1821. Specifically, the same side refers to the same side of the symmetry axis or diagonal of the cross-sectional shape of the airway hole 1821. When the cross-sectional shape of the airway hole 1821 is circular, the same side refers to the same side of the symmetry axis. Fig. 9 In the above example, the same side refers to the upper side or the lower side of the symmetry axis B1. Fig. 9 In the above example, the same side refers to the upper right side or the lower left side of the symmetry axis B2. Fig. 9 In the figure, the same side refers to the left or right side of the symmetry axis B3. When the cross section of the airway hole 1821 is an ellipse, the same side refers to the same side of the symmetry axis. When the cross section of the airway hole 1821 is a prism, the same side refers to the same side of the symmetry axis or diagonal. The figure only gives some examples, and those skilled in the art can adjust as needed, which will not be repeated here.

[0060] The pin holes 1820 are all distributed on the same side of the airway hole 1821, so that the pin holes 1820 occupy less space, so that the side wall between the pin hole 1820 and the airway hole 1821 can be thickened in a direction perpendicular to the central axis A3 of the airway hole 1821. The enhanced strength of the side wall avoids deformation, and further avoids deformation of the airway hole 1821, thereby ensuring the stability of the suction resistance, ensuring the consistency of the taste, and improving the user experience, thereby improving the competitiveness of the product.

[0061] In some embodiments, the side wall between the pin hole 1820 and the airway hole 1821 has a wall thickness of 0.3 mm to 1 mm in a direction perpendicular to the central axis A3 of the airway hole 1821. In some embodiments, the side wall between the pin hole 1820 and the airway hole 1821 has a wall thickness of 0.45 mm to 0.55 mm in a direction perpendicular to the central axis A3 of the airway hole 1821. In some embodiments, the side wall between the pin hole 1820 and the airway hole 1821 has a wall thickness of 0.5 mm in a direction perpendicular to the central axis A3 of the airway hole 1821. In some embodiments, the side wall between the pin hole 1820 and the airway hole 1821 has a wall thickness of 0.7 mm in a direction perpendicular to the central axis A3 of the airway hole 1821. In some embodiments, the side wall between the pin hole 1820 and the airway hole 1821 has a wall thickness of 0.85 mm in a direction perpendicular to the central axis A3 of the airway hole 1821. In some embodiments, the wall thickness of the side wall between the pin hole 1820 and the airway hole 1821 in the direction perpendicular to the central axis A3 of the airway hole 1821 is 0.9 mm. Specifically, the wall thickness of the side wall between the pin hole 1820 and the airway hole 1821 refers to the size of the side wall between the pin hole 1820 and the airway hole 1821 in the direction perpendicular to the central axis A3 of the airway hole 1821, such as Fig.10 The side wall between the pin hole 1820 and the airway hole 1821 is made thicker, and the side wall strength is enhanced to avoid deformation, thereby avoiding deformation of the airway hole 1821, ensuring the stability of the suction resistance and the consistency of the taste.

[0062] In some embodiments, the central axis A1 of the atomizing chamber 1710 is offset from the central axis A3 of the airway hole 1821, so that the atomizing chamber 1710 and the airway hole 1821 are at least partially offset. Figure 4 and Figure 7 As shown, the situation where the airway hole 1821 and the atomizing chamber 1710 are only partially offset and partially opposite is shown. The atomizing chamber 1710 is offset from the airway hole 1821, so that the airway hole 1821 is far away from the heating element 172, and the heating temperature of the heating element 172 does not affect the airway hole 1821, further ensuring that the airway hole 1821 is not deformed, and ensuring the stability of the inhalation resistance. The atomizing chamber 1710 is offset from the airway hole 1821, which also slows down the outflow speed of the condensate from the airway hole 1821 and reduces the accumulation of condensate. In some embodiments, the projection position of the atomizing chamber 1710 in the direction of the axis A1 does not overlap with the projection position of the airway hole 1821 in the direction of the axis A3. The atomizing chamber 1710 and the airway hole 1821 are completely staggered, so that the airway hole 1821 is farther away from the heating element 172, and the heating temperature of the heating element 172 has less influence on the airway hole 1821, further ensuring that the airway hole 1821 does not deform and ensuring the stability of the inhalation resistance. The atomizing chamber 1710 and the airway hole 1821 are completely staggered, further slowing down the outflow speed of the condensate from the airway hole 1821 and further reducing the accumulation of the condensate.

[0063] The groove 1822 is provided at one end of the connecting portion 182 facing the bottom bracket 19. In some embodiments, the plurality of pin holes 1820 are connected to the groove 1822 respectively. In some embodiments, the projection positions of the plurality of pin holes 1820 in the direction of the axis A2 toward the bottom bracket 19 all fall within the range of the groove 1822. The groove 1822 is filled with sealant. The groove 1822 is filled with sealant, which further enhances the sealing effect, prevents the atomized matrix from leaking from the pin hole 1820, and further prevents the atomized matrix from leaking to the electrical connection. The groove 1822 provides a dispensing position for the sealing of the pin hole 1820, which facilitates the dispensing operation.

[0064] See also Fig.14 , Fig.14It is a structural schematic diagram of the sleeve, the bottom bracket and the bottom seal in some embodiments of the present application. The bottom bracket 19 is located at the second end 112 of the housing 11 and is arranged at the end of the bottom seal 18 away from the atomizing core 17. The end portion of the bottom bracket 19 facing the bottom seal 18 is inserted into the receiving groove 1810 of the base 181, and is interference-fitted with the bottom seal 18 to achieve the connection between the bottom bracket 19 and the bottom seal 18. The partial structure of the bottom bracket 19 inserted in the receiving groove 1810 is also connected to the end of the connecting portion 182 away from the atomizing core 17. An air inlet hole is provided at the position corresponding to the bottom bracket 19 and the connecting portion 182, and the air inlet hole is connected to the airway hole 1821. The airway hole 1821 of the connecting portion 182 forms a part of the airflow channel with the atomizing chamber 1710. The airflow channel also includes the channel 150 of the storage member 15, the exhaust channel of the suction nozzle 12 and the air inlet hole of the bottom bracket 19. External air can enter the airway hole 1821 from the air inlet, and then enter the atomization chamber 1710 from the airway hole 1821, and be mixed with the aerosol in the atomization chamber 1710 and discharged from the atomization chamber 1710, and then be discharged to the suction nozzle 12 through the channel 150, and then be discharged from the suction nozzle 12 through the exhaust channel of the suction nozzle 12. In some embodiments, a liquid absorbing member is provided between the bottom bracket 19 and the bottom seal 18, and the liquid absorbing member can absorb the atomized matrix to prevent the atomized matrix from leaking to the electrical connection. The material of the liquid absorbing member can be a fiber with liquid absorbing and liquid retaining capabilities, such as cotton and other materials.

[0065] The side wall of the base 181 is provided with a plurality of convex ridges 183, so that the base 181 and the bottom bracket 19 are easy to assemble, and the leakage-proof effect of the bottom seal 18 is continuous and stable. Due to the use of a structure with multiple convex ridges 183, the contact area between the convex ridges 183 and the bottom bracket 19 is small, and the friction resistance is small. Due to the use of a structure with multiple convex ridges 183, the elastic compression space of the bottom seal 18 is greatly increased, and the relative force between the bottom seal 18 and the bottom bracket 19 is small. The relative force between the bottom seal 18 and the bottom bracket 19 of the structure with multiple convex ridges 183 is small, and the friction resistance is small, which can greatly reduce the wear of the bottom seal 18 caused by repeated plugging and unplugging. The bottom seal 18 with multiple convex ridges 183 has a large elastic compression space, and the relative force with the bottom bracket 19 is small, which greatly prolongs the elastic fatigue time of the bottom seal 18, and can achieve a long-term continuous and stable sealing and leakage-proof effect. The relative force between the bottom seal 18 and the bottom bracket 19 of the multiple convex ridges 183 structure is small, so the interference fit can be appropriately increased. The large interference fit can greatly cushion the impact of the size change of the bottom seal 18 caused by temperature difference, thereby greatly reducing the risk of sealing failure in an environment with large temperature difference.
