[0045] The current aerosol generating device usually includes a mouthpiece and a cigarette cartridge tube (storage part). The mouthpiece is detachably connected to the cigarette cartridge tube. The user can remove the mouthpiece and add an aerosol generating substrate to the cigarette cartridge tube. The aerosol generated by the aerosol generating substrate is heated in the aerosol generating device and flows out of the mouthpiece to be inhaled by the user. However, the current mouthpiece and the cigarette cartridge tube are usually interference fit. The plastic mouthpiece and the plastic cigarette cartridge tube are easily deformed under the influence of the suction temperature, which makes the mouthpiece easily loose relative to the cigarette cartridge tube. In order to solve this problem, the embodiment of the present application provides an atomizer 100 ( Figure 2 ) and aerosol generating device 1000 ( Figure 1 shown).

[0046] See also Figure 1 The aerosol generating device 1000 of the embodiment of the present application includes an atomizer 100 and a battery assembly 300, and the atomizer 100 is electrically connected to the battery assembly 300. The battery assembly 300 can be used to power the heating element in the atomizer 100, so that the heating element of the atomizer 100 can generate heat to heat the aerosol generating substrate.

[0047] See also Figures 2 to 4The atomizer 100 of the embodiment of the present application includes a storage element 10, a nozzle 30 and a connecting member 50. The storage element 10 is provided with a receiving chamber 11. The nozzle 30 is connected to one end of the storage element 10, and the nozzle 30 includes a main body 31 and a mounting portion 33 connected to each other, at least part of the mounting portion 33 extends into the receiving chamber 11, and the main body 31 is located outside the receiving chamber 11. The connecting member 50 is at least partially located in the receiving chamber 11 and is located between the side wall 13 of the storage element 10 and the mounting portion 33. The connecting member 50 is connected to both the side wall 13 and the mounting portion 33 of the storage element 10, and the thermal expansion coefficient of the connecting member 50 is smaller than the thermal expansion coefficient of the storage element 10 and / or the nozzle 30.

[0048] Specifically, the atomizer 100 is a structure for heating the aerosol-generating substrate by powering on to generate an aerosol for the user to inhale. The atomizer 100 may heat the aerosol-generating substrate by, but is not limited to, resistive heating, microwave heating, or laser irradiation heating.

[0049] Please combine Figure 1 The aerosol generating device 1000 is a structure capable of generating an aerosol by heating an aerosol generating substrate. The aerosol may be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is usually liquid or solid at room temperature) and liquid droplets of gas and condensed vapor. The aerosol generating substrate is a product that has been processed and heated to generate an aerosol. The form of the aerosol generating substrate may be liquid, or may be fully solid or semi-solid. In the case where the aerosol generating substrate is liquid, the liquid aerosol generating substrate is a mixed liquid in which substances such as nicotine and nicotine are dissolved, and its solute is a common organic solute and / or inorganic solute such as propylene glycol, vegetable glycerin and pure water. In the present application, the aerosol generating substrate may be a high-viscosity cigarette oil, which can generate an aerosol when heated.

[0050] See also Figure 3 The storage element 10 is a structure for storing an aerosol generating matrix, and the storage element 10 is also used to allow aerosols and gases to flow therethrough. The accommodating chamber 11 is used for storing the aerosol producing matrix therein. The cross-sectional shape of the storage element 10 may be, but is not limited to, circular, elliptical, triangular, quadrilateral or other polygonal shapes. The cross-sectional shape of the storage element 10 of the present application is roughly circular, that is, the storage element 10 is roughly a cylindrical structure. The material of the storage element 10 may be, but is not limited to, metal or plastic. In the case where the material of the storage element 10 is metal, the structural strength of the storage element 10 is high and the service life is long. In the case where the material of the storage element 10 is plastic, the cost of the storage element 10 is low, and the weight is light, which is easy to carry. The material of the storage element 10 of the present application is plastic.

[0051] See also Figure 3 and Figure 4The suction nozzle 30 is a structure that is convenient for inhaling the aerosol generated inside the atomizer 100. When the user uses the aerosol generating device 1000, the battery assembly 300 supplies power to the atomizer 100, and the user inhales the aerosol generated in the atomizer 100 through the suction nozzle 30. Preferably, the suction nozzle 30 is detachably connected to the storage element 10, so that the suction nozzle 30 can be easily removed and the aerosol generating substrate can be added into the accommodating cavity 11 of the storage element 10.

[0052] During the user's suction process, the main body 31 is used to directly contact the user's mouth. The mounting portion 33 is used to connect with the storage member 10 so that the suction nozzle 30 is firmly connected to the storage member 10. Only a part of the mounting portion 33 can extend into the accommodating cavity 11 to connect with the side wall 13 of the storage member 10. The mounting portion 33 can also extend into the accommodating cavity 11 to connect with the side wall 13 of the storage member 10. The main body 31 and the mounting portion 33 can be an integral structure or a split structure. In the case where the main body 31 and the mounting portion 33 are an integral structure, the main body 31 and the mounting portion 33 can be integrally formed, which can reduce the installation steps of the suction nozzle 30. In the case where the main body 31 and the mounting portion 33 are split structures, the mounting portion 33 is detachably or non-detachably connected to the main body 31. Among them, the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection, etc. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit, etc.

[0053] See also Figure 3 and Figure 4 , the connecting member 50 is a structure for connecting the suction nozzle 30 and the storage member 10, so that the suction nozzle 30 and the storage member 10 can be firmly connected. Only a part of the structure of the connecting member 50 can be located in the accommodating chamber 11, or the connecting member 50 can be located entirely in the accommodating chamber 11. The connecting member 50 located in the accommodating chamber 11 is located between the side wall 13 of the storage member 10 and the mounting portion 33. In the radial direction Y of the atomizer 100, at least a part of the connecting member 50 corresponds to both the storage member 10 and the mounting portion 33. The connecting member 50 and the side wall 13 of the storage member 10 can be connected by a snap-fit ​​connection or an interference fit, etc. The connecting member 50 and the mounting portion 33 can be connected by a snap-fit ​​connection or an interference fit, etc.

[0054] Since the storage element 10 and the suction nozzle 30 of the present application are both made of plastic, when the user is inhaling, the aerosol with a higher temperature flows out through the storage element 10 and the suction nozzle 30, and the storage element 10 and the suction nozzle 30 are both susceptible to thermal expansion. When the user stops inhaling, the temperature of the side wall 13 of the storage element 10 and the mounting portion 33 of the suction nozzle 30 decreases and is prone to shrinkage. When the side wall 13 of the storage element 10 and the mounting portion 33 of the suction nozzle 30 expand and contract due to heat, it is easy for the mounting portion 33 to become loose relative to the side wall 13 of the storage element 10, and the connection between the suction nozzle 30 and the storage element 10 is not stable enough. The present application adds a connector 50 between the mounting portion 33 and the side wall 13 of the storage component 10. The thermal expansion coefficient of the connector 50 is smaller than that of the storage component 10 and / or the nozzle 30. The deformation of the connector 50 during temperature changes is small, so that the connector 50 can effectively reduce the deformation of the storage component 10 and / or the nozzle 30 during temperature changes. The deformation of the mounting portion 33 and the corresponding side wall 13 of the storage component 10 is small, so that the connection between the mounting portion 33 and the side wall 13 of the storage component 10 is relatively stable, and the nozzle 30 is not easy to loosen relative to the storage component 10.

[0055] In one embodiment, the thermal expansion coefficient of the connector 50 is smaller than that of the storage element 10, and the connector 50 can effectively prevent the storage element 10 from deforming inward. In another embodiment, the thermal expansion coefficient of the connector 50 is smaller than that of the nozzle 30, and the connector 50 can effectively prevent the mounting portion 33 from deforming outward. In yet another embodiment, the thermal expansion coefficient of the connector 50 is smaller than that of the storage element 10, and the thermal expansion coefficient of the connector 50 is smaller than that of the nozzle 30. On the one hand, the connector 50 can effectively prevent the storage element 10 from deforming inward, and on the other hand, the connector 50 can effectively prevent the mounting portion 33 from deforming outward, so that in the case of temperature changes, the deformation amount of the side wall 13 of the storage element 10 is small, the deformation amount of the mounting portion 33 is also small, and the connection between the mounting portion 33 and the side wall 13 of the storage element 10 is relatively stable. The thermal expansion coefficient of the connector 50 of the present application is smaller than that of the storage element 10, and the thermal expansion coefficient of the connector 50 is smaller than that of the nozzle 30.

[0056] In the atomizer 100 of the embodiment of the present application, the connector is located between the side wall 13 of the storage element 10 and the mounting portion 33, the connector 50 is connected to both the side wall 13 and the mounting portion 33 of the storage element 10, and the thermal expansion coefficient of the connector 50 is smaller than the thermal expansion coefficient of the storage element 10 and / or the nozzle 30. In the case of temperature changes, the connector 50 can effectively prevent the deformation of the storage element 10 and / or the nozzle 30, so that the deformation of the storage element 10 and / or the nozzle 30 is small, and the nozzle 30 is not easy to get loose relative to the storage element 10.

[0057] The atomizer 100 is further described below with reference to the accompanying drawings.

[0058] See also Figure 3 and Figure 4 In some embodiments, the connector 50 is made of metal. When the connector 50 is made of metal, the thermal expansion coefficient of the connector 50 is relatively small. At this time, the thermal expansion coefficient of the connector 50 is smaller than that of the storage element 10, and the thermal expansion coefficient of the connector 50 is smaller than that of the nozzle 30. When the temperature of the side wall 13 and the mounting portion 33 of the storage element 10 changes, the connector 50 has a small thermal expansion coefficient, so the deformation of the connector 50 is relatively small, and the connector 50 can effectively prevent the deformation of the side wall 13 and the mounting portion 33 of the storage element 10. When the deformation of the side wall 13 and the mounting portion 33 of the storage element 10 is relatively small, the connection between the side wall 13 of the storage element 10 and the mounting portion 33 is relatively stable, and the nozzle 30 is not easy to loosen relative to the storage element 10.

[0059] See also Figure 3 and Figure 4 In some embodiments, there are multiple connectors 50, and the multiple connectors 50 are arranged around the mounting portion 33 at intervals. In this case, the connector 50 uses less material, which can save material costs. The number of connectors 50 can be but is not limited to two, three, four, five or more. The multiple connectors 50 are evenly or unevenly arranged around the mounting portion 33.

[0060] In other embodiments, the connector 50 is an annular structure disposed around the mounting portion 33. In this case, there is only one connector 50, which is sleeved on the outer peripheral wall of the mounting portion 33, and the connector 50 is relatively easy to install. In the case where the connector 50 is an annular structure surrounding the mounting portion 33, when the temperature of the side wall 13 of the storage element 10 and the position of the mounting portion 33 changes, the connector 50 can effectively prevent the deformation of various positions of the mounting portion 33, and prevent the partial structure of the mounting portion 33 from deforming outward. At the same time, the connector 50 can also effectively prevent the deformation of various positions of the side wall 13 of the storage element 10 corresponding to the connector 50, and prevent the partial structure of the side wall 13 of the storage element 10 from deforming inward. In this case, the connector 50 has a better effect of preventing the deformation of the mounting portion 33 and the side wall 13 of the storage element 10.

[0061] See also Figures 2 to 4 In some embodiments, the atomizer 100 further includes a fastener 70, which is sleeved on the outer side of the side wall 13 of the storage element 10. In the radial direction Y of the atomizer 100, at least a portion of the fastener 70 corresponds to the connecting member 50, and the thermal expansion coefficient of the fastener 70 is smaller than the thermal expansion coefficient of the storage element 10.

[0062] Among them, the fastener 70 is used to prevent the storage element 10 from deforming toward the outer shape when heated, and on the other hand, the fastener 70 can also play a decorative role to improve the overall aesthetics of the atomizer 100. In the length direction X of the atomizer 100, the fastener 70 can be sleeved on a part of the outer side of the side wall 13 of the storage element 10, and the fastener 70 can also be sleeved on the entire outer side of the side wall 13 of the storage element 10. The fastener 70 of the embodiment of the present application is sleeved on the entire outer side of the side wall 13 of the storage element 10. In the radial direction Y of the atomizer 100, all structures of the connector 50 correspond to the fastener 70. At this time, when the temperature of the side wall 13 of the storage element 10 and the position of the mounting portion 33 changes, the connector 50 prevents the side wall 13 of the storage element 10 from deforming inward and preventing the mounting portion 33 from deforming toward the outer shape, while the fastener 70 can prevent the side wall 13 of the storage element 10 from deforming outward. The fastener 70 is provided on the atomizer 100 to further prevent the side wall 13 and the mounting portion 33 of the storage element 10 from deforming, so that the nozzle 30 is not easily loosened relative to the storage element 10 .

[0063] See also Figures 2 to 4 In some embodiments, the fastener 70 is made of metal. When the fastener 70 is made of metal, the thermal expansion coefficient of the fastener 70 is small. At this time, the thermal expansion coefficient of the fastener 70 is smaller than the thermal expansion coefficient of the storage element 10. When the temperature of the side wall 13 of the storage element 10 and the mounting portion 33 changes, the fastener 70 has a small thermal expansion coefficient, so the deformation of the fastener 70 is small, and the fastener 70 can effectively prevent the side wall 13 of the storage element 10 from deforming toward the outer shape. When the deformation of the side wall 13 of the storage element 10 is small, the connection between the side wall 13 of the storage element 10 and the mounting portion 33 is relatively stable, and the suction nozzle 30 is not easy to loosen relative to the storage element 10.

[0064] See also Figure 3 and Figure 4 In some embodiments, the fastener 70 and the storage element 10 are in an interference fit. At this time, the fastener 70 is tightly connected to the side wall 13 of the storage element 10, and the fastener 70 can further prevent the deformation of the side wall 13 of the storage element 10, so that the installation portion 33 and the side wall 13 of the storage element 10 are more firmly installed, and the suction nozzle 30 is not easy to get loose relative to the storage element 10.

[0065] See also Figures 4 to 6 In some embodiments, the inner side of the side wall 13 of the storage element 10 and the mounting portion 33 jointly clamp the connector 50 , and the connector 50 and the side wall 13 of the storage element 10 and the mounting portion 33 have an interference fit.

[0066] In the case where the connecting member 50 and the side wall 13 of the storage member 10 are in interference fit, the connection between the connecting member 50 and the side wall 13 of the storage member 10 is relatively tight, so that the connecting member 50 can effectively prevent the side wall 13 of the storage member 10 from deforming inward. In the case where the connecting member 50 and the mounting portion 33 are in interference fit, the connection between the connecting member 50 and the mounting portion 33 is relatively tight, so that the connecting member 50 can effectively prevent the mounting portion 33 from deforming outward.

[0067] During the installation process, the fastener 70 is first installed with an interference fit between the outer side of the side wall 13 of the storage component 10, and then the connecting component 50 is installed with an interference fit between the inner side of the side wall 13 of the storage component 10. Finally, the suction nozzle 30 is pressed into the accommodating cavity 11 to make the installation portion 33 and the connecting component 50 have an interference fit.

[0068] See also Figures 7 to 10 In other embodiments, the connector 50 includes a main body 51 and a matching portion 53. The main body 51 includes a first end 511 and a second end 513 opposite to each other. The first end 511 is closer to the main body 31 than the second end 513. The inner side of the side wall 13 of the storage element 10 and the mounting portion 33 jointly clamp the main body 51. The matching portion 53 bends and extends from the first end 511 in a direction close to the center line of the main body 51. The outer peripheral wall of the mounting portion 33 at one end close to the main body 31 is provided with a groove 331. The matching portion 53 is inserted into the groove 331. The main body 51 and the storage element 10 are interference-fitted. Alternatively, the side wall 13 of the storage element 10 is provided with a through hole 131. The matching portion 53 bends and extends from the second end 513 in a direction away from the center line of the main body 51. The matching portion 53 is inserted into the through hole 131. The main body 51 and the suction nozzle 30 are interference-fitted.

[0069] The main body 51 is used to prevent the side wall 13 of the storage element 10 from deforming inward, and the main body 51 is also used to prevent the mounting portion 33 from deforming outward, so that the connection between the mounting portion 33 and the side wall 13 of the storage element 10 is relatively stable, and the suction nozzle 30 is not easy to loosen relative to the storage element 10. The matching portion 53 is used to connect with the side wall 13 or the mounting portion 33 of the storage element 10, so that the connecting member 50 is firmly connected with the side wall 13 or the mounting portion 33 of the storage element 10. The number of the matching portion 53 can be one, in which case the matching portion 53 is an annular matching portion 53 extending from the first end 511 or the second end 513 of the main body 51. The number of the matching portions 53 can also be multiple, in which case the multiple matching portions 53 extend from the first end 511 or the second end 513 of the main body 51 and are spaced from each other, and the multiple matching portions 53 are evenly or unevenly distributed on the first end 511 or the second end 513 of the main body 51.

[0070] See also Figure 7 and Figure 8In one example, the matching portion 53 is bent and extended from the first end 511 in a direction close to the center line of the main body 51, and a groove 331 is provided on the outer peripheral wall of the end of the mounting portion 33 close to the main body 31, and the matching portion 53 is inserted into the groove 331, and the main body 51 and the storage element 10 are interference fit. During the installation process, the connecting member 50 is firstly installed with the inner side of the side wall 13 of the storage element 10 by interference fit, and then the suction nozzle 30 is installed into the accommodating cavity 11 so that the matching portion 53 is matched with the groove 331. At this time, the connection between the connecting member 50 and the side wall 13 of the storage element 10 is relatively tight, and the connection between the connecting member 50 and the mounting portion 33 is also relatively stable, and the connecting member 50 is not easy to be loosened relative to the side wall 13 and / or the mounting portion 33 of the storage element 10. In addition, this form of installation can also avoid the problem that the suction nozzle 30 cannot be pressed into the accommodating cavity 11 due to the fluctuation of tolerance between the side wall 13 of the storage element 10, the mounting portion 33 and the connecting member 50.

[0071] See also Fig.10 In another example, the matching portion 53 is bent and extended from the second end 513 in a direction away from the center line of the main body 51, and the side wall 13 of the storage unit 10 is provided with a through hole 131, and the matching portion 53 is inserted into the through hole 131, and the main body 51 and the suction nozzle 30 are interference fit. During the installation process, the connecting member 50 is first installed into the inner side of the side wall 13 of the storage unit 10 so that the matching portion 53 is matched with the through hole 131, and then the suction nozzle 30 is pressed and installed into the accommodating cavity 11 so that the main body 51 and the mounting portion 33 are interference fit. At this time, the connection between the connecting member 50 and the side wall 13 of the storage unit 10 is relatively stable, and the connection between the connecting member 50 and the mounting portion 33 is also relatively tight, and the connecting member 50 is not easy to loosen relative to the side wall 13 and / or the mounting portion 33 of the storage unit 10. Furthermore, this type of installation can also avoid the problem that the suction nozzle 30 cannot be pressed into the accommodating cavity 11 due to fluctuations in tolerances between the side wall 13 of the storage element 10 , the mounting portion 33 and the connecting member 50 .

[0072] See also Figures 10 to 12 In some other embodiments, a groove 331 is provided on the outer peripheral wall of one end of the mounting portion 33 connected to the main body portion 31; a through hole 131 is provided on the side wall 13 of the storage element 10; and the connecting member 50 includes a main body portion 51, a first matching portion 531, and a second matching portion 533. The main body portion 51 includes a first end 511 and a second end 513 opposite to each other, and the first end 511 is closer to the main body portion 31 than the second end 513. The inner side of the side wall 13 of the storage element 10 and the mounting portion 33 jointly clamp the main body portion 51. The first matching portion 531 bends and extends from the first end 511 in a direction close to the center line of the main body portion 51, and the first matching portion 531 is inserted into the groove 331. The second matching portion 533 extends from the second end 513 and bends in a direction away from the center line of the main body portion 51, and the second matching portion 533 is inserted into the through hole 131.

[0073] The main body 51 is used to prevent the side wall 13 of the storage element 10 from deforming inwards, and the main body 51 is also used to prevent the mounting portion 33 from deforming outwards, so that the mounting portion 33 is more firmly connected to the side wall 13 of the storage element 10, and the suction nozzle 30 is not easily loosened relative to the storage element 10. The first matching portion 531 is used to connect with the mounting portion 33, so that the connecting member 50 is firmly connected to the mounting portion 33. The second matching portion 533 is used to connect with the side wall 13 of the storage element 10, so that the connecting member 50 is firmly connected to the side wall 13 of the storage element 10.

[0074] The number of the first matching portion 531 may be one, and in this case, the first matching portion 531 is an annular matching portion 53 extending from the first end 511 of the main body 51. The number of the first matching portion 531 may also be multiple, and in this case, multiple first matching portions 531 extend from the first end 511 of the main body 51 and are spaced apart from each other, and the multiple first matching portions 531 are evenly or unevenly distributed on the first end 511 of the main body 51. The number of the second matching portions 533 may be one or more, and preferably, the number of the second matching portions 533 is multiple, and the multiple second matching portions 533 extend from the second end 513 of the main body 51 and are spaced apart from each other. In this case, there are also multiple through holes 131 on the side wall 13 of the storage element 10, and the number of the multiple through holes 131 corresponds one-to-one to the number of the multiple second matching portions 533.

[0075] During the installation process, the connector 50 is first installed into the inner side of the side wall 13 of the storage element 10 so that the second matching portion 533 matches the through hole 131, and then the suction nozzle 30 is installed into the accommodating cavity 11 so that the first matching portion 531 matches the groove 331. At this time, the stability of the connection between the connector 50 and the storage element 10 and the mounting portion 33 can be further enhanced, and the connector 50 is not easy to loosen relative to the side wall 13 and the mounting portion 33 of the storage element 10. In addition, this form of installation can also avoid the problem that the suction nozzle 30 cannot be pressed into the accommodating cavity 11 due to fluctuations in tolerances between the side wall 13 of the storage element 10, the mounting portion 33 and the connector 50.

[0076] See also Figure 6 In some embodiments, the mounting portion 33 is an annular structure. In this case, the mounting portion 33 is an integrated structure, the structure of the mounting portion 33 is relatively simple, and the processing is relatively convenient.

[0077] See also Fig. 9In other embodiments, when the mounting portion 33 is provided with a groove 331, the mounting portion 33 includes at least two sub-portions 333 spaced apart from each other, and a sub-groove 335 is provided on the outer peripheral wall of one end of each sub-portion 333 adjacent to the main body portion 31, and at least two sub-grooves 335 together form the groove 331. The number of sub-portions 333 of the mounting portion 33 may include two, three, four, five or more, and there is a gap between two adjacent sub-portions 333. When the first end 511 of the main body portion 51 is provided with a matching portion 53 (first matching portion 531), the connecting member 50 is first connected to the inner side of the side wall 13 of the storage member 10, and the mounting portion 33 is then inserted into the accommodating cavity 11. Since the mating portion 53 (the first mating portion 531) is toward the center of the connector 50, when the mounting portion 33 includes at least two sub-portions 333 spaced apart from each other, when the mounting portion 33 is inserted into the accommodating cavity 11, when the multiple sub-portions 333 of the mounting portion 33 come into contact with the mating portion 53 (the first mating portion 531), the multiple sub-portions 333 of the mounting portion 33 can be deformed toward the center of the mounting portion 33, thereby facilitating the mounting portion 33 to enter the accommodating cavity 11.

[0078] See also Figure 3 In some embodiments, the accommodating chamber 11 includes a storage chamber 111 and an air guiding chamber 113 which are spaced apart from each other. The storage chamber 111 is used to store the aerosol generating substrate, and the air guiding chamber 113 is used to allow the aerosol generated by the aerosol generating substrate to flow out from the mouthpiece 30. The mouthpiece 30 is provided with a channel 35, and the channel 35 is connected to the air guiding chamber 113. The atomizer 100 also includes a sealing member 90, which is disposed in the accommodating chamber 11. The sealing member 90 is used to block the communication between the storage chamber 111 and the channel 35, and allow the communication between the air guiding chamber 113 and the channel 35.

[0079] The storage unit 10 includes a body and a partition. The body may be a columnar structure. The partition is installed in the body and divides the cavity of the body into a storage cavity 111 and an air guide cavity 113 that are not connected to each other. The body and the partition may be an integral structure or a split structure. In the case where the body and the partition are an integral structure, the body and the partition can be integrally formed, and the assembly steps of the storage unit 10 are relatively simple. In the case where the body and the partition are split structures, the replacement and maintenance of the partition can be facilitated. At this time, the partition can be detachably or non-detachably installed on the body. Among them, the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection, etc. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit, etc.

[0080] Preferably, the volume of the storage chamber 111 is greater than the volume of the air guide chamber 113, so that more aerosol generating substrate can be stored in the storage element 10. The user does not need to frequently add the aerosol generating substrate to the storage element 10, and the user's experience is better. During the user's inhalation process, the aerosol generated by the heated aerosol generating substrate will enter the air guide chamber 113, and flow out of the channel 35 through the air guide chamber 113 to the outside of the atomizer 100 for the user to inhale.

[0081] The seal 90 is used to prevent the aerosol-generating substrate in the storage chamber 111 from flowing into the air guide chamber 113 and the channel 35. The aerosol flowing out of the air guide chamber 113 can flow into the channel 35 through the seal 90. The seal 90 can be made of materials such as rubber, silicone, plastic or synthetic fiber.

[0082] See also Figure 3 , Figure 4 , Figure 7 and Fig.10 Specifically, in some embodiments, the sealing member 90 is provided with a first through-hole 91 and a second through-hole 93 spaced apart, the first through-hole 91 is connected to the storage cavity 111, and the second through-hole 93 is connected to the air guide cavity 113 and the channel 35; the nozzle 30 further includes a blocking portion 37, one end of the blocking portion 37 is connected to the inner wall of the channel 35, and the other end of the blocking portion 37 extends into the first through-hole 91.

[0083] The first perforation 91 is used to allow the aerosol-generating matrix from the outside to enter the storage chamber 111. When it is necessary to add the aerosol-generating matrix to the storage chamber 111, the nozzle 30 can be removed from the storage element 10, and the aerosol-generating matrix can be added to the storage chamber 111 through the first perforation 91. After the aerosol-generating matrix is ​​added to the storage chamber 111, the nozzle 30 is connected to the storage element 10, and the blocking portion 37 extends into the first perforation 91 to block the first perforation 91, thereby preventing the aerosol-generating matrix in the storage chamber 111 from flowing into the channel 35 and / or the air guide chamber 113 from the first perforation 91. The second perforation 93 is used to allow the aerosol in the air guide chamber 113 to flow out of the channel 35, so that the aerosol can flow out of the atomizer 100 to be inhaled by the user.
