The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0046] An aerosol generating device generally includes a mouthpiece and a storage member (cartridge tube). A storage cavity and an air guiding cavity are provided in the storage member. The mouthpiece is detachably connected to the storage member. A user can remove the mouthpiece to add an aerosol generating matrix into the storage cavity in the storage member. The aerosol formed after the aerosol generating matrix in the storage cavity is heated flows out from the mouthpiece through the air guiding cavity to be sucked by the user. In order to improve the problem of liquid leakage and hole blockage, the air guiding cavity in the current storage member is set as a non-centered airway structure. However, when the air guiding cavity is a non-centered airway structure, when the mouthpiece is installed on the storage member, the mouthpiece needs to be inserted into the storage member from a specific direction, and the assembly efficiency of this method is low. To solve this problem, an embodiment of the present application provides an atomizer 100 ( Figure 2 as shown) and an aerosol generating device 1000 ( Figure 1 as shown).

[0047] Please refer to Figure 1 , the aerosol generating device 1000 according to the embodiment of the present application includes an atomizer 100 and a battery assembly 300. The atomizer 100 is electrically connected to the battery assembly 300. The battery assembly 300 can be used to supply power to the heating element in the atomizer 100, so that the heating element of the atomizer 100 can generate heat to heat the aerosol generating matrix.

[0048] Please refer to Figure 2 and Figure 3 , the atomizer 100 according to the embodiment of the present application includes a storage member 10, a first connecting member 50, a mouthpiece 30 and a second connecting member 70. A receiving cavity 11 is provided in the storage member 10. The first connecting member 50 is sleeved on the storage member 10 and connected to the outer wall of the storage member 10. The mouthpiece 30 includes a connected body portion 31 and a mounting portion 33. At least part of the second connecting member 70 is located in the receiving cavity 11. The second connecting member 70 is in interference fit with the inner wall of the mounting portion 33. At least part of the mounting portion 33 extends into the receiving cavity 11 and is in interference fit with the inner wall of the storage member 10. The body portion 31 is located outside the receiving cavity 11. In the length direction X perpendicular to the atomizer 100, at least part of the second connecting member 70 corresponds to the first connecting member 50.

[0049] Specifically, the atomizer 100 is a structure that is powered on to heat an aerosol - generating substrate to generate an aerosol for a user to inhale. The heating method by which the atomizer 100 heats the aerosol - generating substrate can be, but is not limited to, resistive heating, microwave heating, laser irradiation heating, etc.

[0050] Please refer to Figure 1 , the aerosol - generating device 1000 is a structure capable of generating an aerosol by heating an aerosol - generating substrate. The aerosol can be visible or invisible and can include vapor (e.g., fine particulate matter in a gaseous state, which is usually liquid or solid at room temperature), as well as gas and liquid droplets of condensed vapor. The aerosol - generating substrate is an article that has been processed and can generate an aerosol after being heated. The form of the aerosol - generating substrate can be liquid, fully solid, or semi - solid. When the aerosol - generating substrate is in a liquid state, the liquid aerosol - generating substrate is a mixed liquid in which substances such as nicotine and nicotine are dissolved, and its solutes are common organic solutes and / or inorganic solutes such as propylene glycol, vegetable glycerin, and pure water. In this application, the aerosol - generating substrate can be a high - viscosity e - liquid (such as sesame oil, etc.), and the high - viscosity e - liquid can generate an aerosol when heated.

[0051] Please refer to Figure 2 , Figure 3 and Figure 5 , the storage member 10 is a structure for storing the aerosol - generating substrate, and the storage member 10 is also used to allow the aerosol and gas to flow through it. The accommodation cavity 11 is used for storing the aerosol - production substrate therein. The cross - sectional shape of the storage member 10 can be, but is not limited to, circular, elliptical, triangular, quadrilateral, or other polygonal shapes, etc. The cross - sectional shape of the storage member 10 in this application is approximately circular, that is, the storage member 10 is generally a cylindrical structure. The material of the storage member 10 can be, but is not limited to, metal or plastic, etc. When the material of the storage member 10 is metal, the storage member 10 has a higher structural strength and a longer service life. When the material of the storage member 10 is plastic, the storage member 10 has a lower cost, is lighter in weight, and is convenient to carry.

[0052] The first connector 50 is sleeved on the outer wall of the storage member 10, and the first connector 50 can be a circular - ring structure. The first connector 50 can be used to prevent the storage member 10 from deforming outward when heated, and the first connector 50 can also play a decorative role to a certain extent to improve the overall aesthetics of the atomizer 100. In the length direction X of the atomizer 100, the first connector 50 can be sleeved on a partial position of the outer wall of the storage member 10, or the first connector 50 can be sleeved on the entire outer wall of the storage member 10. In the embodiment of this application, the first connector 50 is sleeved on a partial position of the outer wall of the storage member 10 near one end of the mouthpiece 30.

[0053] Please refer to Figures 2 to 5, the mouthpiece 30 is a structure that facilitates a user to suck the aerosol generated inside the atomizer 100. When the user uses the aerosol generating device 1000, the battery assembly 300 powers the atomizer 100, and the user sucks the aerosol generated in the atomizer 100 through the mouthpiece 30. Preferably, the mouthpiece 30 is detachably connected to the storage member 10, so that it is convenient to remove the mouthpiece 30 and add the aerosol generating matrix into the accommodating cavity 11 of the storage member 10.

[0054] During the user's sucking process, the body portion 31 is used to directly contact the user's mouth. The mounting portion 33 is in interference fit with the inner wall of the storage member 10 to stably connect the mouthpiece 30 and the storage member 10. Only a part of the structure of the mounting portion 33 can extend into the accommodating cavity 11 to be in interference fit with the inner wall of the storage member 10. The mounting portion 33 can also entirely extend into the accommodating cavity 11 to be in interference fit with the inner wall of the storage member 10. When the mounting portion 33 is in interference fit with the storage member 10, no other connecting elements (such as buckles, etc.) need to be provided on the storage member 10 and the mounting portion 33, and the structures of the storage member 10 and the mouthpiece 30 are relatively simple and the processing is relatively simple. The body portion 31 and the mounting portion 33 can be an integral structure or a split structure. When the body portion 31 and the mounting portion 33 are an integral structure, the body portion 31 and the mounting portion 33 can be integrally formed, which can reduce the installation steps of the mouthpiece 30. When the body portion 31 and the mounting portion 33 are a split structure, the mounting portion 33 is detachably or non-detachably connected to the body portion 31. Among them, the detachable installation methods include but are not limited to threaded connection, screw connection or snap connection, etc. The non-detachable installation methods include but are not limited to welding, gluing connection or interference fit, etc.

[0055] When the second connecting member 70 is in interference fit with the inner wall of the mounting portion 33, the connection between the second connecting member 70 and the mounting portion 33 is relatively tight, and the second connecting member 70 can prevent the mounting portion 33 from deforming inward when heated. In some embodiments, the mounting portion 33 can be an annular structure, and the second connecting member 70 is also an annular structure. At this time, the second connecting member 70 can be connected to all positions of the inner wall of the mounting portion 33, so that the connection between the second connecting member 70 and the mounting portion 33 is more stable, and the effect of the second connecting member 70 blocking the mounting portion 33 from deforming inward is also better. During the installation of the mouthpiece 30 and the storage member 10, the first connecting member 50 is first connected to the outer wall of the storage member 10, the second connecting member 70 is in interference fit with the inner wall of the mounting portion 33, and finally the mouthpiece 30 and the storage member 10 are pressed together so that the outer wall of the mounting portion 33 and the inner wall of the storage member 10 are in interference fit, thereby realizing the blind installation between the mouthpiece 30 and the storage member 10. The installation between the mouthpiece 30 and the storage member 10 is relatively simple and the assembly efficiency is relatively high.

[0056] The first connecting member 50 is first connected to the storage member 10. The first connecting member 50 can, to a certain extent, prevent the storage member 10 from deforming outward when the temperature rises. The second connecting member 70 is first in interference fit with the inner wall of the mounting portion 33. The second connecting member 70 can, to a certain extent, prevent the mounting portion 33 from deforming inward when the temperature drops. Thus, the storage member 10 and the nozzle 30 are not easily deformed when the temperature changes. When the storage member 10 is connected to the nozzle 30, the mounting portion 33 can be in interference fit with the inner wall of the storage member 10, so that the connection between the nozzle 30 and the storage member 10 is relatively firm. At the same time, after the nozzle 30 is connected to the storage member 10, when at least part of the second connecting member 70 corresponds to the first connecting member 50 in the length direction X of the vertical atomizer 100, the first connecting member 50 can, to a certain extent, prevent the storage member 10 from deforming outward when the temperature rises, and the second connecting member 70 can, to a certain extent, prevent the mounting portion 33 and the storage member 10 from deforming inward when the temperature drops. Thus, the connection between the nozzle 30 and the storage member 10 is relatively firm, and the nozzle 30 can be prevented from loosening relative to the storage member 10.

[0057] Please refer to Figure 5 , since the first connecting member 50 is an annular structure sleeved on the outer wall of the storage member 10 and the second connecting member 70 is an annular structure in interference fit with the inner wall of the mounting portion 33, the sizes of both the first connecting member 50 and the second connecting member 70 are relatively small. When the first connecting member 50 and the second connecting member 70 are added to the atomizer 100, the volume of the atomizer 100 will not be increased too much, and the overall size of the atomizer 100 is relatively small, which is convenient for users to hold, place and carry.

[0058] In the atomizer 100 according to the embodiment of the present application, the first connecting member 50 is sleeved on the storage member 10 and connected to the outer wall of the storage member 10, and the second connecting member 70 is in interference fit with the inner wall of the mounting portion 33. During the installation process, the first connecting member 50 is first connected to the outer wall of the storage member 10, the second connecting member 70 is in interference fit with the inner wall of the mounting portion 33, and finally the nozzle 30 is pressed against the storage member 10 so that the outer wall of the mounting portion 33 is in interference fit with the inner wall of the storage member 10, thereby realizing blind installation between the nozzle 30 and the storage member 10. The installation between the nozzle 30 and the storage member 10 is relatively simple and the assembly efficiency is relatively high. At the same time, the first connecting member 50 and the second connecting member 70 can double-clamp the storage member 10 and the nozzle 30, and the connection between the nozzle 30 and the storage member 10 is relatively firm, and the nozzle 30 can be prevented from loosening relative to the storage member 10.

[0059] The atomizer 100 will be further described below with reference to the accompanying drawings.

[0060] Currently, the connection between the nozzle and the cartridge tube is usually an interference fit. Since both the storage member and the nozzle are typically made of plastic, when the relatively hot aerosol flows out through the storage member and the nozzle during the user's suction process, both the storage member and the nozzle are prone to thermal expansion. When the user stops suction, as the surrounding temperature decreases, the side wall of the storage member and the mounting portion of the nozzle are prone to cold shrinkage. Due to thermal expansion and contraction, the mounting portion is prone to becoming loose relative to the side wall of the storage member, and the connection between the nozzle and the storage member is not firm enough.

[0061] Please refer to Figure 3 and Figure 4 In an embodiment of the present application, the coefficient of thermal expansion of the first connecting member 50 is less than that of the storage member 10; the coefficient of thermal expansion of the second connecting member 70 is less than that of the nozzle 30.

[0062] When the coefficient of thermal expansion of the first connecting member 50 is less than that of the storage member 10, during the process of temperature increase, the amount of deformation of the first connecting member 50 towards the outside is less than that of the storage member 10 towards the outside. Thus, the first connecting member 50 can effectively prevent the storage member 10 from deforming towards the outside during the temperature increase process, the connection between the mounting portion 33 and the storage member 10 is relatively firm, and the nozzle 30 is not easily loosened relative to the storage member 10.

[0063] When the coefficient of thermal expansion of the second connecting member 70 is less than that of the nozzle 30, during the process of temperature decrease, the amount of deformation of the second connecting member 70 towards the inside is less than that of the mounting portion 33 towards the inside. Thus, the second connecting member 70 can effectively prevent the mounting portion 33 from deforming towards the inside during the temperature decrease process, the connection between the mounting portion 33 and the storage member 10 is relatively firm, and the nozzle 30 is not easily loosened relative to the storage member 10.

[0064] In the length direction X of the vertical atomizer 100, at least a part of the second connecting member 70 corresponds to the first connecting member 50. Preferably, in the length direction X of the vertical atomizer 100, all structures of the second connecting member 70 correspond to the first connecting member 50. At this time, in the length direction X of the vertical atomizer 100, the first connecting member 50 and the second connecting member 70 jointly clamp the storage member 10 and the mounting portion 33, and the first connecting member 50 and the second connecting member 70 can effectively prevent the storage member 10 and the mounting portion 33 from deforming when the temperature changes. Thus, the connection between the storage member 10 and the nozzle 30 is relatively firm, and the nozzle 30 is not easily loosened relative to the storage member 10.

[0065] Please refer to Figure 3 and Figure 4 Specifically, in some embodiments, the storage member 10 is a plastic part, and the first connecting member 50 is a metal part; the nozzle 30 is a plastic part, and the second connecting member 70 is a metal part.

[0066] When the storage member 10 is a plastic part and the first connecting member 50 is a metal part, the storage member 10 has a relatively large coefficient of thermal expansion, and the first connecting member 50 has a relatively small coefficient of thermal expansion. The coefficient of thermal expansion of the first connecting member 50 is smaller than that of the storage member 10. When the temperature rises, due to the small coefficient of thermal expansion of the first connecting member 50, the deformation amount of the first connecting member 50 is relatively small, and the first connecting member 50 can effectively prevent the storage member 10 from deforming outward. The connection between the side wall of the storage member 10 and the mounting portion 33 is relatively stable, and the nozzle 30 is not easily loosened relative to the storage member 10.

[0067] When the nozzle 30 is a plastic part and the second connecting member 70 is a metal part, the nozzle 30 has a relatively large coefficient of thermal expansion, and the second connecting member 70 has a relatively small coefficient of thermal expansion. The coefficient of thermal expansion of the second connecting member 70 is smaller than that of the storage member 10. When the temperature drops, due to the small coefficient of thermal expansion of the second connecting member 70, the deformation amount of the second connecting member 70 is relatively small, and the second connecting member 70 can effectively prevent the storage member 10 from deforming outward. The connection between the side wall of the storage member 10 and the mounting portion 33 is relatively stable, and the nozzle 30 is not easily loosened relative to the storage member 10.

[0068] Please refer to Figures 3 to 5 , in some embodiments, a first groove 311 is provided on the outer wall of one end of the body portion 31 close to the storage member 10, and a second groove 13 is provided on the outer wall of one end of the storage member 10 connected to the nozzle 30. The first groove 311 communicates with the second groove 13, and the first connecting member 50 is installed in the first groove 311 and the second groove 13.

[0069] Among them, the first groove 311 and the second groove 13 are used for installing the first connecting member 50 therein. When the first connecting member 50 is installed in the first groove 311 and the second groove 13, the overall volume of the atomizer 100 is relatively small, which is convenient for users to carry. Preferably, the depth of the first groove 311 is the same as the thickness of the first connecting member 50, and the depth of the second groove 13 is the same as the thickness of the first connecting member 50. Thus, when the first connecting member 50 is installed in the first groove 311 and the second groove 13, the outer contour diameter of the first connecting member 50 is the same as the outer contour diameter of the storage member 10, and the overall aesthetic degree of the atomization chamber is better.

[0070] While the first connecting member 50 of the present application is sleeved on the outer wall of the storage member 10, at least a part of the first connecting member 50 further extends to be connected to the body portion 31. Thus, while preventing the storage member 10 from deforming outwardly due to heat, the first connecting member 50 is also used to connect the storage member 10 and the body portion 31 simultaneously, so as to make the connection between the storage member 10 and the nozzle 30 more stable. During the installation process, the first connecting member 50 is first installed in the second groove 13, and the second connecting member 70 is in interference fit with the inner wall of the installation portion 33. Subsequently, during the blind installation of the nozzle 30 and the storage member 10, at least a part of the first connecting member 50 extends into the first groove 311, so that the storage member 10 and the nozzle 30 are tightly connected.

[0071] Please refer to Figures 3 to 6 , in some embodiments, the first connecting member 50 is in interference fit with the bottom wall of the first groove 311, and / or the first connecting member 50 is in interference fit with the bottom wall of the second groove 13. Preferably, the first connecting member 50 is in interference fit with the bottom wall of the first groove 311, and the first connecting member 50 is in interference fit with the bottom wall of the second groove 13. At this time, the connection between the first connecting member 50 and the outer wall of the storage member 10 is relatively tight, so that the first connecting member 50 can effectively prevent the storage member 10 from deforming outwardly. The first connecting member 50 is also relatively tightly connected to the outer wall of the body portion 31, so that the first connecting member 50 can effectively connect the storage member 10 and the body portion 31, making the connection between the storage member 10 and the nozzle 30 tighter.

[0072] Please refer to Figures 7 to 10 , in some other embodiments, the first connecting member 50 includes a connecting body 51 and a fitting portion 53. The connecting body 51 includes opposite first end 511 and second end 513, and the first end 511 is closer to the body portion 31 than the second end 513. The connecting body 51 is located in the first groove 311 and the second groove 13. The fitting portion 53 bends and extends from the first end 511 in a direction close to the central axis of the connecting body 51. A third groove 313 communicating with the first groove 311 is provided on the outer wall of the body portion 31. The third groove 313 is recessed from the bottom wall of the first groove 311 in a direction close to the central axis of the body portion 31, and the fitting portion 53 is snapped into the third groove 313, and the connecting body 51 is in interference fit with the bottom wall of the first groove 311; or, the fitting portion 53 bends and extends from the second end 513 in a direction close to the central axis of the connecting body 51. A fourth groove 15 is provided on the outer wall of the storage member 10. The fourth groove 15 is recessed from the bottom wall of the second groove 13 in a direction close to the central axis of the storage member 10, and the fitting portion 53 is snapped into the fourth groove 15, and the connecting body 51 is in interference fit with the bottom wall of the second groove 13.

[0073] Specifically, the connecting body 51 is used to prevent the storage member 10 from deforming outwardly due to heat, so that the connection between the storage member 10 and the mounting portion 33 is relatively stable, and the nozzle 30 is not easily loosened relative to the storage member 10. The engaging portion 53 is used to connect with the outer wall of the storage member 10 or the outer wall of the main body portion 31 to increase the connection strength between the nozzle 30 and the storage member 10. The number of the engaging portions 53 can be one. In this case, the engaging portion 53 is an annular engaging portion 53 extending from the first end 511 or the second end 513 of the connecting body 51. The number of the engaging portions 53 can also be multiple. In this case, multiple engaging portions 53 extend from the first end 511 or the second end 513 of the connecting body 51 and are spaced from each other, and the multiple engaging portions 53 are distributed evenly or unevenly on the first end 511 or the second end 513 of the connecting body 51. In the embodiment of the present application, the number of the engaging portions 53 is one, and one engaging portion 53 is an annular structure extending from the first end 511 or the second end 513 of the connecting body 51.

[0074] Please refer to Figures 7 to 10 , in an example, the engaging portion 53 bends and extends from the first end 511 in a direction close to the central axis of the connecting body 51. A third groove 313 communicating with the first groove 311 is provided on the outer wall of the main body portion 31. The third groove 313 is recessed from the bottom wall of the first groove 311 in a direction close to the central axis of the main body portion 31. The engaging portion 53 is snapped into the third groove 313, and the connecting body 51 is in interference fit with the storage member 10. During the installation process, the first connecting member 50 is first installed in interference with the outer wall of the storage member 10, and then the nozzle 30 is inserted into the accommodating cavity 11 so that the engaging portion 53 is engaged with the third groove 313. At this time, the connection between the first connecting member 50 and the side wall of the storage member 10 is relatively tight, the connection between the first connecting member 50 and the main body portion 31 is relatively stable. While preventing the storage member 10 from deforming outwardly, the first connecting member 50 can also increase the connection strength between the nozzle 30 and the storage member 10, further preventing the nozzle 30 from loosening relative to the storage member 10.

[0075] In another example, the engaging portion 53 extends by bending from the second end 513 in a direction away from the central axis of the connecting body 51. A fourth groove 15 is provided on the outer wall of the storage member 10. The fourth groove 15 is recessed from the bottom wall of the second groove 13 in a direction approaching the central axis of the storage member 10. The engaging portion 53 is snapped into the fourth groove 15, and the connecting body 51 and the nozzle 30 are in interference fit. During the installation process, first, the engaging portion 53 of the first connecting member 50 is engaged with the fourth groove 15, and then the nozzle 30 is inserted into the accommodating cavity 11 so that the connecting body 51 and the body portion 31 are installed in interference fit. When the engaging portion 53 is snapped into the fourth groove 15, a part of the structure of the connecting body 51 can contact the bottom wall of the second groove 13, and this part of the structure of the connecting body 51 can effectively prevent the storage member 10 from deforming outward. At the same time, since the engaging portion 53 is engaged with the fourth groove 15, another part of the structure of the connecting body 51 is in interference fit with the body portion 31, so that the connection strength between the nozzle 30 and the storage member 10 is relatively high, and the nozzle 30 can be further prevented from loosening relative to the storage member 10.

[0076] Please refer to Figures 11 to 14 , in some other embodiments, the body portion 31 is provided with a third groove 313 communicating with the first groove 311. The third groove 313 is recessed from the bottom wall of the first groove 311 in a direction approaching the central axis of the body portion 31; a fourth groove 15 is provided on the side wall of the storage member 10. The fourth groove 15 is recessed from the bottom wall of the second groove 13 in a direction approaching the central axis of the storage member 10; the connecting member includes a connecting body 51, a first engaging portion 531 and a second engaging portion 533. The connecting body 51 includes an opposite first end 511 and a second end 513. The first end 511 is closer to the body portion 31 than the second end 513, and the connecting body 51 is located in the first groove 311 and the second groove 13. The first engaging portion 531 extends by bending from the first end 511 in a direction approaching the central axis of the connecting body 51, and the first engaging portion 531 is snapped into the third groove 313. The second engaging portion 533 extends by bending from the second end 513 in a direction approaching the central axis of the connecting body 51, and the second engaging portion 533 is snapped into the fourth groove 15.

[0077] Among them, the connecting body 51 is used to prevent the storage member 10 from deforming outwardly due to heat, so that the connection between the storage member 10 and the mounting portion 33 is relatively stable, and the suction nozzle 30 is not easily detached from the storage member 10. The fitting portion 53 is used to connect with the outer wall of the storage member 10 or the outer wall of the main body portion 31 to increase the connection strength between the suction nozzle 30 and the storage member 10. The number of the fitting portions 53 can be one. At this time, the fitting portion 53 is an annular fitting portion 53 extending from the first end 511 or the second end 513 of the connecting body 51. The number of the fitting portions 53 can also be multiple. At this time, the multiple fitting portions 53 extend from the first end 511 or the second end 513 of the connecting body 51 and are spaced from each other, and the multiple fitting portions 53 are distributed evenly or unevenly on the first end 511 or the second end 513 of the connecting body 51. In the embodiment of the present application, the number of the fitting portions 53 is one, and one fitting portion 53 is an annular structure extending from the first end 511 or the second end 513 of the connecting body 51.

[0078] During the installation process, first, the first fitting portion 531 is fitted with the fourth groove 15, and then the suction nozzle 30 is inserted into the accommodating cavity 11 so that the second fitting portion 533 is fitted with the third groove 313. When the first fitting portion 531 is snapped into the fourth groove 15 and the second fitting portion 533 is snapped into the third groove 313, a part of the structure of the connecting body 51 can contact the bottom wall of the second groove 13. This part of the structure of the connecting body 51 can effectively prevent the storage member 10 from deforming outwardly. At the same time, it can further enhance the stability of the connection between the storage member 10 and the mounting portion 33, and the suction nozzle 30 is not easily detached from the storage member 10.

[0079] Please refer to Figures 11 to 13 , in some embodiments, a first chamfer 17 is provided on the outer wall of the end of the storage member 10 connected to the suction nozzle 30, that is, the outer wall of the end of the storage member 10 connected to the suction nozzle 30 extends obliquely. The outer wall of the storage member 10 extends obliquely from the top end of the storage member 10 in a direction away from the central axis of the storage member 10. When the second fitting portion 533 is provided at the second end 513 of the connecting body 51, when the first connecting member 50 is inserted into the second groove 13 from the top of the storage member 10, the first chamfer 17 can guide the second fitting portion 533 so that the first connecting member 50 can be smoothly pressed into the second groove 13. In addition, the setting of the first chamfer 17 removes the sharp corner at the top of the storage member 10, which can avoid scratching the second fitting portion 533 by the sharp corner at the top of the storage member 10 and can play a certain protective role for the second fitting portion 533.

[0080] Please refer to Figure 8 , Figure 9 , Figure 12 and Figure 13, in some other embodiments, a second chamfer 315 is provided on the outer wall of the end of the body portion 31 connected to the storage member 10. That is, the outer wall of the end of the body portion 31 connected to the storage member 10 extends obliquely, and the outer wall of the body portion 31 extends obliquely from the bottom end of the body portion 31 in a direction away from the central axis of the body portion 31. When a first mating portion 531 is provided at the first end 511 of the connecting body 51, when the nozzle 30 is inserted into the accommodating cavity 11 from the top of the first connecting member 50, the second chamfer 315 cooperates with the first mating portion 531, so as to be able to guide the nozzle 30, so that the nozzle 30 can be accurately inserted into the accommodating cavity 11. In addition, the setting of the second chamfer 315 removes the sharp corner at the bottom of the body portion 31, which can avoid scratching the first mating portion 531 by the bottom of the body portion 31 and can play a certain protective role for the first mating portion 531.

[0081] Please refer to Figure 8 , Figure 9 , Figure 12 and Figure 13 , in still some other embodiments, a first chamfer 17 is provided on the outer wall of the end of the storage member 10 connected to the nozzle 30, and a second chamfer 315 is provided on the outer wall of the end of the body portion 31 connected to the storage member 10. At this time, when the first connecting member 50 is inserted into the second groove 13 from the top of the storage member 10, the first chamfer 17 can guide the second mating portion 533, and at the same time, it can also avoid scratching the second mating portion 533 by the sharp corner at the top of the storage member 10. When the nozzle 30 is inserted into the accommodating cavity 11 from the top of the first connecting member 50, the second chamfer 315 cooperates with the first mating portion 531, so as to be able to guide the nozzle 30, and at the same time, it can also avoid scratching the first mating portion 531 by the bottom of the body portion 31.

[0082] Please refer to Figure 3 , Figure 7 , Figure 11 and Figure 15 , in some embodiments, the accommodating cavity 11 includes a storage cavity 111 and a gas guiding cavity 113 that are spaced apart from each other. The storage cavity 111 is used for storing the aerosol generating matrix. The inner wall of the storage cavity 111 extends towards the central axis of the storage member 10 and forms a mounting table 19. The gas guiding cavity 113 is used for the aerosol generated by the aerosol generating matrix to flow out from the nozzle 30; the nozzle 30 is provided with a channel 35, and the channel 35 communicates with the gas guiding cavity 113; the atomizer 100 further includes a sealing member 90, the sealing member 90 is arranged in the accommodating cavity 11 and is at least partially carried on the mounting table 19, and the sealing member 90 is used to block the communication between the storage cavity 111 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, the sealing member 90 is provided with a through hole 91, the through hole 91 communicates with the storage cavity 111, and the other end of the blocking portion 37 extends into the through hole 91.

[0083] Specifically, the storage member 10 includes a main body and a partition member. The main body can be a columnar structure. The partition member is installed in the main body and divides the cavity of the main body into a non-communicating storage cavity 111 and an air guiding cavity 113. The main body and the partition member can be an integral structure or a split structure. In the case where the main body and the partition member are an integral structure, the main body and the partition member can be integrally formed, and the assembly steps of the storage member 10 are relatively simple. In the case where the main body and the partition member are a split structure, it is convenient for the replacement and maintenance of the partition member. At this time, the partition member is detachably or non-detachably installed on the main body. Among them, the detachable installation methods include but are not limited to threaded connection, screw connection, or snap connection, etc. The non-detachable installation methods include but are not limited to welding, glue connection, or interference fit, etc.

[0084] Preferably, the volume of the storage cavity 111 is larger than the volume of the air guiding cavity 113, so that more aerosol generating matrix can be stored in the storage member 10. Users do not need to frequently add the aerosol generating matrix to the storage member 10, and the user experience is better. During the user's suction process, the aerosol formed after the aerosol generating matrix is heated will enter the air guiding cavity 113 and flow out of the channel 35 to the outside of the atomizer 100 through the air guiding cavity 113 for the user to suction.

[0085] Please refer to Figure 3 、 Figure 7 、 Figure 11 and Figure 15 As shown in, the seal 90 is used to prevent the aerosol generating matrix in the storage cavity 111 from flowing into the air guiding cavity 113 and the channel 35. The seal 90 can be made of materials such as rubber, silica gel, plastic, or synthetic fiber. The mounting table 19 is used to carry the seal 90. On the one hand, it can make the seal 90 be stably installed in the accommodating cavity 11, and on the other hand, it can also play a limiting role on the seal 90 to prevent the seal 90 from extending too much into the storage cavity 111 and occupying a large space in the storage cavity 111. A part of the structure of the seal 90 is carried on the mounting table 19, and another part of the structure of the seal 90 can also be in interference fit with the inner wall of the storage cavity 111, so as to further block the communication between the storage cavity 111 and the channel 35.

[0086] Please refer to Figure 4 、 Figure 8 、 Figure 12 and Figure 15, the inner wall of the air guiding cavity 113 also extends towards the central axis of the storage member 10 and forms a boss 18. In the length direction X of the atomizer 100, the top surface of the boss 18 and the top surface of the seal 90 are on the same horizontal plane. When the mouthpiece 30 is inserted into the storage member 10, the boss 18 and the seal 90 jointly support the bottom of the mounting portion 33, thereby further stably connecting the mouthpiece 30 to the storage member 10. The boss 18 and the seal 90 can also limit the position of the mounting portion 33 to remind the user that the mouthpiece 30 has been installed in place.

[0087] Please refer to Figure 4 , Figure 8 , Figure 12 and Figure 15 , the perforation 91 is used for allowing the external aerosol generating matrix to enter the storage cavity 111. When it is necessary to add the aerosol generating matrix into the storage cavity 111, the mouthpiece 30 can be removed from the storage member 10, and the aerosol generating matrix can be added into the storage cavity 111 through the perforation 91. After adding the aerosol generating matrix into the storage cavity 111, the mouthpiece 30 is connected to the storage member 10. At this time, the blocking portion 37 extends into the perforation 91 to block the perforation 91, thereby preventing the aerosol generating matrix in the storage cavity 111 from flowing into the channel 35 and / or the air guiding cavity 113 through the perforation 91. The blocking portion 37 of the present application is located at the central position of the cross-section of the mouthpiece 30, that is, the central axis of the blocking portion 37 can coincide with the central axis of the mouthpiece 30. Preferably, in the direction perpendicular to the length direction X of the atomizer 100, the perforation 91 can be located at the center of the cross-section of the accommodating cavity 11, so that when the mouthpiece 30 is installed on the storage member 10, the blocking portion 37 can smoothly extend into the perforation 91.

[0088] During the installation of the mouthpiece 30, first install the seal 90 into the accommodating cavity 11 (on the mounting table 19), then install the first connecting member 50 on the storage member 10, install the second connecting member 70 on the mouthpiece 30, and finally assemble the mouthpiece 30 and the storage member 10. At this time, the mouthpiece 30 does not need to be connected to the storage member 10 from a specific direction, and the installation between the mouthpiece 30 and the storage member 10 can be blind installation, and the installation efficiency between the mouthpiece 30 and the storage member 10 is relatively high.

[0089] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. At the same time, other embodiments can be derived from the above-described embodiments, so that structural and logical substitutions and changes can be made without departing from the scope of the present disclosure.

[0090] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
