[0002] Common aerosol generating devices include an atomizer and a power supply. The atomizer is detachably connected to the power supply, enabling the user to replace different atomizers as needed.

[0003] After the atomizer is connected to the power supply, the induction air passage of the atomizer communicates with the air flow passage of the power supply. During the user's suction process, the air pressure change inside the atomizer can affect the air flow in the air flow passage, thereby triggering the microphone in the power supply to control the normal operation of the aerosol generating device.

[0004] In some aerosol generating devices, the atomizer is connected to the power supply in a rotatable manner, such as a threaded connection. During the process of connecting the atomizer to the power supply, special attention needs to be paid to the relative rotation angle between the atomizer and the power supply to align the inlet of the induction air passage with the outlet of the air flow passage, resulting in inconvenience for the user.

[0066] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0067] It should also be understood that the term "and / or" used in the specification and appended claims of the present application refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0068] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0069] It should be understood that the orientation or positional relationships indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0070] In addition, in the description of the specification and the appended claims of the present application, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions, and should not be construed as indicating or implying relative importance.

[0071] The reference to "one embodiment" or "some embodiments" etc. in the specification of the present application means that specific features, structures or characteristics described in connection with that embodiment are included in one or more embodiments of the present application. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways. "A plurality" means two or more.

[0072] Figure 1 is a schematic structural diagram of an aerosol generating device provided by an embodiment of the present application. As Figure 1 shown, the aerosol generating device includes a power source 100 and an atomizer 200. The power source 100 has a recess 1001, and the atomizer 200 has a protrusion 2001. The protrusion 2001 is inserted into the recess 1001. The power source 100 is used to supply power to the atomizer 200.

[0073] In some small aerosol generating devices, the sizes and weights of the power source 100 and the atomizer 200 are relatively small, and the power source 100 and the atomizer 200 are usually connected by a magnetic attraction method, which is convenient to use. In some large aerosol generating devices, the sizes and weights of the power source 100 and the atomizer 200 are relatively large, and it is difficult to stably connect the power source 100 and the atomizer 200 by the magnetic attraction method. Therefore, a rotational connection is usually adopted. For example, an internal thread is formed on the inner wall of the recess 1001, and an external thread is formed on the outer wall of the protrusion 2001, and the power source 100 and the atomizer 200 are connected together by a threaded connection method.

[0074] For another example, Figure 2 is an enlarged schematic diagram of the connection part between the power source and the atomizer provided by an embodiment of the present application. AsFigure 2 As shown, an annular rib 2002 is formed on the outer wall of the convex part 2001, and an annular clamping groove 1002 is formed on the inner wall of the concave part 1001. The convex part 2001 is inserted into the concave part 1001, and the annular rib 2002 is snapped into the annular clamping groove 1002, so that the power supply 100 and the atomizer 200 can rotate relative to each other but remain connected.

[0075] As Figure 1 shown, the atomizer 200 further has an induction air passage 2a, and the inlet of the induction air passage 2a is located at the end of the atomizer 200. During the process of the user sucking through the mouthpiece 300, the air flow will enter from the inlet of the induction air passage 2a. The power supply 100 has an air flow passage 1a, and the outlet of the air flow passage 1a is located at the end of the power supply 100. The atomizer 200 is connected to the power supply 100, and the inlet of the induction air passage 2a needs to be aligned with the outlet of the air flow passage 1a. During the user's sucking process, the air flow in the air flow passage 1a will flow into the induction air passage 2a, triggering the microphone in the power supply 100 to make the aerosol generating device work.

[0076] During the process of connecting the atomizer 200 and the power supply 100, the user often needs to pay special attention to the relative rotation angle of the two to ensure that the outlet of the induction air passage 2a of the atomizer 200 is aligned with the outlet of the air flow passage 1a of the power supply 100. This makes the connection process of the atomizer 200 and the power supply 100 relatively troublesome and affects the convenience of using the aerosol generating device.

[0077] Figure 3 is a schematic structural diagram of a housing assembly of a power supply provided by an embodiment of the present application. As Figure 3 shown, the housing assembly of the power supply includes a first outer shell 40. The first outer shell 40 includes a first connection part 41 and a first main body part 42. The first main body part 42 is used to accommodate the power supply component 60.

[0078] The first connection part 41 is connected to the first main body part 42, and the first connection part 41 is used for rotatable connection with the atomizer 200.

[0079] The outer surface of the first main body part 42 has a first annular groove 40a, and the first annular groove 40a surrounds the first connection part 41. For example, the first annular groove 40a can be coaxially arranged with the first connection part 41. The first annular groove 40a is used to cooperate with the outer surface of the atomizer 200 to form an annular cavity communicating with the induction air passage 2a of the atomizer 200.

[0080] The first main body part 42 has an air flow passage 1a. One end of the air flow passage 1a is located in the first annular groove 40a, and the other end of the air flow passage 1a is located inside the first main body part 42. The other end of the air flow passage 1a is used for connection to the microphone 50.

[0081] By setting the first housing 40 in the housing assembly of the power supply 100 to include a first connection portion 41 and a first main body portion 42, a first annular groove 40a and an air flow channel 1a are provided in the first main body portion 42. One end of the air flow channel 1a is located in the first annular groove 40a. When the power supply 100 is connected to the atomizer 200 through the first connection portion 41, the first annular groove 40a can form an annular cavity with the outer surface of the atomizer 200. This annular cavity communicates with the induction air channel 2a of the atomizer 200, so that the air flow channel 1a communicates with the induction air channel 2a of the atomizer 200 through this annular cavity. The first annular groove 40a surrounds the first connection portion 41. When rotatably connected to the atomizer 200 through the first connection portion 41, even if the relative rotation angle between the atomizer 200 and the power supply 100 is different each time during the connection process, any angle within 0° to 360°, the annular cavity formed by the first annular groove 40a and the outer surface of the atomizer 200 can always communicate the air flow channel 1a and the induction air channel 2a. When the user connects the atomizer 200 and the power supply 100, there is no need to pay attention to the relative rotation angle between the atomizer 200 and the power supply 100, which facilitates the user to connect the atomizer 200 and the power supply 100 and makes the use of the aerosol generating device more convenient.

[0082] Figure 4 It is an exploded structural schematic diagram of a housing assembly provided by an embodiment of the present application, as Figure 4 shown. In some examples, the first main body portion 42 includes a support frame 422 and a cover plate 421. The cover plate 421 is located on the outer surface of the support frame 422. The first annular groove 40a is located on the side of the cover plate 421 away from the support frame 422.

[0083] The support frame 422 is used to accommodate the power supply assembly 60 and provide an installation basis for the power supply assembly 60. The cover plate 421 is arranged on the outer surface of the support frame 422 to provide shielding and prevent external dust and liquid from entering the support frame 422. Different power supplies 100 may have different external structures, while the support frame 422 may adopt the same structure, so that only different cover plates 421 need to be set, which can reduce production costs. When connecting the power supply 100 and the atomizer 200, the cover plate 421 contacts the atomizer 200. By providing a separate cover plate 421, it is also convenient to process the cover plate 421 and make the cover plate 421 better cooperate with the atomizer 200.

[0084] As Figure 4 shown, the first housing 40 may further include a dust cover 43 and a battery cover 44, and the dust cover 43 and the battery cover 44 can be respectively installed on the surface of the support frame 422.

[0085] The housing assembly of the power supply 100 may further include a key cap 45, and the key cap 45 can be exposed outside the first housing 40 to facilitate user operation.

[0086] In some examples, the first connection part 41 has a thread for connecting the atomizer 200.

[0087] Adopting the threaded connection method to connect the atomizer 200 can make the connection between the atomizer 200 and the power supply 100 more firm.

[0088] The first connection part 41 can be cylindrical. For example, the first connection part 41 can be a cylindrical tubular structure. The thread can be located on the inner side wall or the outer side wall of the first connection part 41.

[0089] As an example, as Figure 4 shown, the first connection part 41 is connected to the support frame 422, and the cover plate 421 has a through hole 421a exposing the first connection part 41.

[0090] When the power supply 100 is connected to the atomizer 200, a part of the atomizer 200 can pass through the through hole 421a of the cover plate 421 and be connected to the first connection part 41. The first connection part 41 is connected to the support frame 422. When replacing the cover plate 421, there is no need to disassemble the first connection part 41.

[0091] Exemplarily, the first connection part 41 is located on the side of the cover plate 421 close to the support frame 422. The first connection part 41 has an internal thread. When the atomizer 200 is connected to the power supply 100, a part of the atomizer 200 can be inserted into the first connection part 41 and be connected to the first connection part 41 by a thread.

[0092] Figure 5 is a schematic structural diagram of a cover plate provided by an embodiment of the present application. As Figure 5 shown, the outer surface of the first main body part 42 has a first plane area 40b, and the first annular groove 40a is located in the first plane area 40b.

[0093] In this example, the first plane area 40b includes the surface of the cover plate 421 away from the support frame 422.

[0094] Setting the surface of the cover plate 421 away from the support frame 422 as a plane enables the cover plate 421 to better fit the outer surface of the atomizer 200 when connecting the atomizer 200 and the power supply 100. The first annular groove 40a and the outer surface of the atomizer 200 form an annular cavity with better airtightness, so that during the use of the aerosol generating device, the microphone in the power supply 100 can be triggered more accurately.

[0095] As Figure 5 shown, the first annular groove 40a is circular, and the diameter of the first annular groove 40a can be 10 mm to 20 mm.

[0096] The diameter of the first annular groove 40a may be one of the diameter of the inner sidewall of the first annular groove 40a, the diameter of the outer sidewall of the first annular groove 40a, and the average value of the diameters of the inner sidewall and the outer sidewall of the first annular groove 40a. The inner sidewall of the first annular groove 40a is the sidewall of the first annular groove 40a close to the first connection portion 41, and the outer sidewall is the sidewall away from the first connection portion 41.

[0097] The larger the diameter of the first annular groove 40a, the longer the inner edge and the outer edge of the first annular groove 40a. When the atomizer 200 is connected to the power supply 100, the risk of leakage of the formed annular cavity is higher. When the diameter of the first annular groove 40a is set between 10 mm and 20 mm, the leakage risk of the annular cavity is lower, and there is also sufficient space inside the first annular groove 40a to arrange the first connection portion 41 with dimensions meeting the design requirements, avoiding the dimensions of the first connection portion 41 being restricted and affecting the structural strength of the first connection portion 41.

[0098] In some examples, the diameter of the first annular groove 40a may be 13 mm to 17 mm. For example, the diameter of the first annular groove 40a may be 15 mm.

[0099] In some examples, the difference between the ring width of the first annular groove 40a and the diameter of the air flow channel 1a does not exceed 1 mm.

[0100] The ring width of the first annular groove 40a refers to the difference between the radius of the outer sidewall and the radius of the inner sidewall of the first annular groove 40a. The diameter of the air flow channel 1a may refer to the diameter of one end of the air flow channel 1a located inside the first annular groove 40a, that is, the diameter of the outlet of the air flow channel 1a.

[0101] Setting the ring width of the first annular groove 40a to be not much different from the diameter of the air flow channel 1a, within 1 mm, can prevent the volume of the annular cavity formed when the atomizer 200 is connected to the power supply 100 from being too large. When the diameter of the first annular groove 40a is fixed, the larger the ring width of the first annular groove 40a, the larger the volume of the annular cavity formed when the atomizer 200 is connected to the power supply 100, and the larger volume annular cavity may affect the sensitivity during microphone detection.

[0102] Exemplarily, the ring width of the first annular groove 40a may be the same as the diameter of the air flow channel 1a.

[0103] Figure 6 It is a cross-sectional view of a cover plate provided by an embodiment of the present application. As Figure 6 shown, the first main body portion 42 may further include a first sealing rib 4211 and a second sealing rib 4212.

[0104] The first sealing rib 4211 is located in the first planar region 40b and is arranged around the first connecting portion 41. The first sealing rib 4211 is located inside the first annular groove 40a. The second sealing rib 4212 is located in the first planar region 40b and is arranged around the first connecting portion 41. The second sealing rib 4212 is located outside the first annular groove 40a.

[0105] When connecting the atomizer 200 and the power supply 100, the first sealing rib 4211 and the second sealing rib 4212 can respectively press the outer surface of the power supply 100, thereby improving the airtightness on both sides inside and outside the first annular groove 40a, and forming an annular cavity with better airtightness between the first annular groove 40a and the outer surface of the power supply 100.

[0106] In some other possible implementation manners, only the first sealing rib 4211 or only the second sealing rib 4212 may be provided on the surface of the cover plate 421 to reduce the process cost.

[0107] Figure 7 It is a schematic diagram of the internal structure of a power supply provided by an embodiment of the present application. As Figure 7 shown, the power supply includes a power supply component 60, a microphone 50, and a housing component of the power supply as Figures 11 to 6 shown. The power supply component 60 and the microphone 50 are located in the first main body portion 42, and the microphone 50 is communicated with the air flow channel 1a.

[0108] When connecting the atomizer 200 to the power supply 100, even if the relative rotation angle between the atomizer 200 and the power supply 100 is different each time during the connection process, any angle within 0° to 360°, the annular cavity formed between the first annular groove 40a and the outer surface of the atomizer 200 can always communicate the air flow channel 1a and the induction air channel 2a. When the user connects the atomizer 200 and the power supply 100, there is no need to pay attention to the relative rotation angle between the atomizer 200 and the power supply 100, which is convenient for the user to connect the atomizer 200 and the power supply 100, and makes the use of the aerosol generating device more convenient.

[0109] As Figure 7 shown, the power supply component 60 may include a battery 61, a circuit board 62, a third electrode 63, and a fourth electrode 64. The battery 61 and the circuit board 62 can be respectively installed in the support frame 422. The microphone 50, the third electrode 63, and the fourth electrode 64 can be located on the side of the battery 61 close to the cover plate 421. The microphone 50, the third electrode 63, and the fourth electrode 64 can be respectively connected to the circuit board 62. For example, the microphone 50 can be connected to the circuit board 62 through a wire.

[0110] Exemplarily, the third electrode 63 can be cylindrical and is coaxially arranged with the first connecting portion 41.

[0111] The fourth electrode 64 may be located on the inner wall of the first connecting portion 41. Exemplarily, the fourth electrode 64 may be a conductive layer formed on the inner wall of the first connecting portion 41, for example, a metal plating layer.

[0112] In some possible implementation manners, the first connecting portion 41 may be a conductive member. For example, the first connecting portion 41 may be a metal member, and the fourth electrode 64 may have the same structure as the first connecting portion 41, that is, the first connecting portion 41 is reused as the fourth electrode 64.

[0113] The microphone 50 may be arranged facing the inlet of the air flow channel 1a. Exemplarily, the power supply 100 may further include a microphone cover 51, and the microphone cover 51 is sleeved outside the microphone 50. The microphone cover 51 has a gas guiding channel, one end of the gas guiding channel is communicated with the inlet of the air flow channel 1a, and the other end of the gas guiding channel faces the microphone 50.

[0114] As Figure 7 shown, the power supply 100 may further include a display panel 65. The display panel 65 is located on the side of the circuit board 62 away from the support frame 422, and the display panel 65 is electrically connected to the circuit board 62.

[0115] Arranging the display panel 65 on one side of the circuit board 62 so that the display panel 65 and the circuit board 62 are arranged in a parallel or approximately parallel manner saves space and can make the structure of the power supply 100 more compact.

[0116] Figure 8 is a schematic structural diagram of a housing assembly of an atomizer provided by an embodiment of the present application. As Figure 8 shown, the housing assembly includes a second outer shell 20. The second outer shell 20 includes a second connecting portion 21 and a second main body portion 22. The second main body portion 22 is used to accommodate the atomization assembly of the atomizer 200.

[0117] The second connecting portion 21 is connected to the second main body portion 22, and the second connecting portion 21 is used for rotatably connecting with the power supply 100.

[0118] Figure 9 is a partial structural schematic diagram of a second outer shell provided by an embodiment of the present application. As Figure 9 shown, the outer surface of the second main body portion 22 has a second annular groove 20a, and the second annular groove 20a surrounds the second connecting portion 21. For example, the second annular groove 20a may be coaxially arranged with the second connecting portion 21. The second annular groove 20a is used to cooperate with the outer surface of the power supply 100 to form an annular cavity communicated with the air flow channel 1a of the power supply 100.

[0119] The second main body portion 22 has an induction air channel 2a. One end of the induction air channel 2a is located in the second annular groove 20a, and the other end of the induction air channel 2a is located inside the second main body portion 22. The other end of the induction air channel 2a is used for communicating with the mouthpiece 300.

[0120] By setting the second outer shell 20 in the housing assembly of the atomizer 200 to include a second connecting portion 21 and a second main body portion 22, a second annular groove 20a and an induction air passage 2a are provided in the second main body portion 22. One end of the induction air passage 2a is located in the second annular groove 20a. When the atomizer 200 is connected to the power supply 100 through the second connecting portion 21, the second annular groove 20a can form an annular cavity with the outer surface of the power supply 100. This annular cavity communicates with the air flow passage 1a of the power supply 100, so that the induction air passage 2a communicates with the air flow passage 1a of the power supply 100 through this annular cavity. The second annular groove 20a surrounds the second connecting portion 21. When rotatably connected to the power supply 100 through the second connecting portion 21, even if the relative rotation angle between the atomizer 200 and the power supply 100 is different each time during the connection process, any angle within 0° to 360°, the annular cavity formed by the second annular groove 20a and the outer surface of the power supply 100 can always communicate the induction air passage 2a and the air flow passage 1a. When the user connects the atomizer 200 and the power supply 100, there is no need to pay attention to the relative rotation angle between the atomizer 200 and the power supply 100, which facilitates the user to connect the atomizer 200 and the power supply 100 and makes the use of the aerosol generating device more convenient.

[0121] Referring to Figure 8 As shown, in some examples, the second main body portion 22 may include a first cover body 221, a second cover body 222 and a liquid storage housing 223. The first cover body 221 is located at one end of the liquid storage housing 223, and the second cover body 222 is located at the other end of the liquid storage housing 223. The first cover body 221, the liquid storage housing 223 and the second cover body 222 are detachably connected to facilitate the assembly of the atomizer 200.

[0122] As Figure 8 shown, the second cover body 222 can be used to connect the mouthpiece 300.

[0123] In some examples, the housing assembly of the atomizer 200 may further include a mouthpiece 300, and the mouthpiece 300 can be connected to the second outer shell 20. For example, the mouthpiece 300 can be connected to the second cover body 222.

[0124] As an example, the mouthpiece 300 can be detachably connected to the second cover body 222 to facilitate the replacement of the mouthpiece 300.

[0125] In other examples, the mouthpiece 300 can also be fixedly connected to the second cover body 222. For example, the mouthpiece 300 and the second cover body 222 are integrally formed.

[0126] As Figure 8 shown, the second connecting portion 21 can be connected to the first cover body 221, and the second annular groove 20a can be located on the side of the first cover body 221 away from the liquid storage housing 223.

[0127] The second connecting portion 21 and the first cover body 221 can be fixedly connected. As an example, the second connecting portion 21 and the first cover body 221 can be an integrally formed structure. In some other possible implementation manners, the second connecting portion 21 and the first cover body 221 can also be two independent components.

[0128] In some examples, the second connecting portion 21 has a thread for connecting to the power source 100.

[0129] Adopting the threaded connection method to connect the power source 100 can make the connection between the atomizer 200 and the power source 100 more firm.

[0130] The second connecting portion 21 can be cylindrical. For example, the second connecting portion 21 can be a cylindrical tubular structure. The thread can be located on the outer sidewall or the inner sidewall of the second connecting portion 21.

[0131] As an example, as Figure 9 shown, the second connecting portion 21 protrudes from the outer surface of the first cover body 221, that is, the second connecting portion 21 is located on the side of the first cover body 221 away from the liquid storage housing 223. The second connecting portion 21 has an external thread. When connecting to the power source 100, the second connecting portion 21 can be inserted into the power source 100 and connected to the power source 100 through the thread.

[0132] Figure 10 is a schematic structural diagram of a first cover body provided by an embodiment of the present application. As Figure 10 shown, in some other possible implementation manners, the second connecting portion 21 is located on the side of the first cover body 221 close to the liquid storage housing 223, and the second connecting portion 21 has an internal thread. When connecting to the power source 100, the second connecting portion 21 can be sleeved on a part of the outside of the power source 100 and connected to the power source 100 through the thread.

[0133] As Figure 9 shown, the outer surface of the second main body portion 22 has a second planar region 20b, and the second annular groove 20a is located in the second planar region 20b.

[0134] In this example, the second planar region 20b includes the surface of the first cover body 221 on the side away from the liquid storage housing 223. The second planar region 20b is annular and surrounds the second connecting portion 21. For example, the second annular groove 20a can be coaxial with the second planar region 20b.

[0135] The surface of the first cover body 221 away from the liquid storage housing 223 is set as a flat surface, so that when the atomizer 200 is connected to the power supply 100, the first cover body 221 can better fit the outer surface of the power supply 100, and the second annular groove 20a and the outer surface of the power supply 100 form an annular cavity with better airtightness, so that during the use of the aerosol generating device, the microphone in the power supply 100 can be triggered more accurately.

[0136] As Figure 9 shown, the second annular groove 20a is circular. The diameter of the second annular groove 20a can be 10 mm to 20 mm.

[0137] The diameter of the second annular groove 20a can refer to one of the diameter of the inner side wall of the second annular groove 20a, the diameter of the outer side wall of the second annular groove 20a, and the average value of the diameters of the inner side wall and the outer side wall of the second annular groove 20a. The inner side wall of the second annular groove 20a is the side wall of the second annular groove 20a close to the second connecting portion 21, and the outer side wall is the side wall away from the second connecting portion 21.

[0138] The larger the diameter of the second annular groove 20a, the longer the inner and outer edges of the second annular groove 20a. When the atomizer 200 is connected to the power supply 100, the risk of leakage of the formed annular cavity is higher. Setting the diameter of the second annular groove 20a at 10 mm to 20 mm results in a lower risk of leakage of the annular cavity, and there is also sufficient space inside the second annular groove 20a to arrange the second connecting portion 21 with dimensions meeting the design requirements, avoiding the dimensions of the second connecting portion 21 being restricted and affecting the structural strength of the second connecting portion 21.

[0139] In some examples, the diameter of the second annular groove 20a can be 13 mm to 17 mm. For example, the diameter of the second annular groove 20a can be 15 mm.

[0140] In some examples, the difference between the ring width of the second annular groove 20a and the diameter of the induction air passage 2a does not exceed 1 mm.

[0141] The ring width of the second annular groove 20a refers to the difference between the radius of the outer side wall and the radius of the inner side wall of the second annular groove 20a. The diameter of the induction air passage 2a can refer to the diameter of one end of the induction air passage 2a located inside the second annular groove 20a, that is, the diameter of the inlet of the induction air passage 2a.

[0142] The width of the second annular groove 20a is set to be not much different from the diameter of the induction air passage 2a, within 1 mm, which can prevent the volume of the annular cavity formed when the atomizer 200 is connected to the power supply 100 from being too large. When the diameter of the second annular groove 20a is fixed, the larger the width of the second annular groove 20a, the larger the volume of the annular cavity formed when the atomizer 200 is connected to the power supply 100. A larger-volume annular cavity may affect the sensitivity during microphone detection.

[0143] Exemplarily, the width of the second annular groove 20a can be the same as the diameter of the induction air passage 2a.

[0144] Figure 11 It is a partial cross-sectional view of a second main body portion provided by an embodiment of the present application, and the cross-section of the first cover 221 is shown in the figure. As Figure 11 shown, the second main body portion 22 may further include a third sealing rib 2211 and a fourth sealing rib 2212.

[0145] The third sealing rib 2211 is located in the second planar region 20b and surrounds the second connecting portion 21. The third sealing rib 2211 is located inside the second annular groove 20a. The fourth sealing rib 2212 is located in the second planar region 20b and surrounds the second connecting portion 21. The fourth sealing rib 2212 is located outside the second annular groove 20a.

[0146] When connecting the atomizer 200 and the power supply 100, the third sealing rib 2211 and the fourth sealing rib 2212 can respectively press the outer surface of the power supply 100, thereby improving the airtightness on both the inside and outside of the second annular groove 20a, and forming an annular cavity with better airtightness between the second annular groove 20a and the outer surface of the power supply 100.

[0147] In some other possible implementation manners, only the third sealing rib 2211 or only the fourth sealing rib 2212 may be provided on the surface of the first cover 221 to reduce the process cost.

[0148] As Figure 11 shown, one side of the first cover 221 close to the liquid storage housing 223 has a convex column 2213, and one end of the induction air passage 2a far from the second annular groove 20a is located at the end of the convex column 2213.

[0149] The induction air passage 2a penetrates through the first cover 221. The inlet of the induction air passage 2a is located on the outer side of the first cover 221, that is, the side away from the liquid storage housing 223, and the outlet of the induction air passage 2a is located on the inner side of the first cover 221, that is, the side close to the liquid storage housing 223. During the use of the atomizer 200, the aerosol matrix or the formed condensate inside may adhere to the inner side of the first cover 221. By providing the convex column 2213 on the inner side of the first cover 221 and arranging the outlet of the induction air passage 2a at the end of the convex column 2213, the risk that the aerosol matrix or the formed condensate blocks the induction air passage 2a and even leaks to the outside of the atomizer 200 through the induction air passage 2a can be reduced.

[0150] Exemplarily, the height of the convex column 2213 can be 1 mm to 5 mm. For example, 2 mm or 3 mm.

[0151] Referring again to Figure 8 As shown, the housing assembly of the atomizer 200 may further include a bracket 224. A part of the bracket 224 is located in the liquid storage housing 223, and another part of the bracket 224 is located between the liquid storage housing 223 and the second cover 222.

[0152] Figure 12 is a schematic internal structure diagram of a housing assembly of an atomizer provided by an embodiment of the present application. Figure 12 The approximate flow direction of the internal air flow of the housing assembly is schematically shown. As Figure 12 shown, the bracket 224 has an atomization channel 224a. The inlet of the atomization channel 224a is close to the first cover 221, that is, the distance from the inlet of the atomization channel 224a to the first cover 221 is less than the distance from the outlet of the atomization channel 224a to the first cover 221. The inlet of the atomization channel 224a is communicated with the induction air passage 2a. The outlet of the atomization channel 224a is close to the second cover 222, that is, the distance from the outlet of the atomization channel 224a to the second cover 222 is less than the distance from the inlet of the atomization channel 224a to the second cover 222.

[0153] Figure 13 is a schematic internal structure diagram of a housing assembly of an atomizer provided by an embodiment of the present application. Figure 13 The approximate flow direction of the internal air flow of the housing assembly is schematically shown. Figure 13 The cross-section shown in Figure 12 is perpendicular to the cross-section shown in Figure 13 As shown, the bracket 224 further has a main air passage 224b. The inlet of the main air passage 224b is located on the outer surface of the part of the bracket 224 exposed between the liquid storage housing 223 and the second cover 222, and the outlet of the main air passage 224b is communicated with the inlet of the atomization channel 224a.

[0154] The main airway 224b is the main passage for external air to enter the interior of the atomizer 200 during the suction process. The atomization channel 224a is used to accommodate the atomization component 30 and is also the part where the aerosol is formed. During the user's suction process, external air enters the main airway 224b and then enters the entrance of the atomization channel 224a via the main airway 224b. After being mixed with the aerosol generated by the atomization component 30 in the atomization channel 224a, it is discharged from the outlet of the atomization channel 224a and finally discharged from the atomizer 200 via the mouthpiece 300.

[0155] In this example, a part of the bracket 224 is exposed between the liquid storage housing 223 and the second cover 222. By arranging the entrance of the main airway 224b on the outer surface of the exposed part of the bracket 224, the entrance of the main airway 224b is closer to the second cover 222, and the airflow entering the atomizer 200 from the entrance of the main airway 224b will undergo a U-turn, extending the path of the airflow. During the operation of the atomizer 200, it will generate heat inside. For example, the atomization component 30 will generate heat during operation. The longer path of the airflow can enable the airflow to be heated more sufficiently, so that the temperature of the airflow can rise to a more appropriate level.

[0156] The bracket 224 can have multiple main airways 224b, and the multiple main airways 224b can be distributed around the atomization channel 224a. For example, they are arranged at equal angular intervals around the atomization channel 224a. As an example, the bracket 224 can have two main airways 224b, and the two main airways 224b are arranged symmetrically about the center. Arranging multiple main airways 224b is beneficial to increasing the air intake of the atomizer 200. By arranging the multiple main airways 224b around the atomization channel 224a, the airflow entering the atomization channel 224a can be made more uniform and symmetrical, which is beneficial to improving the atomization effect.

[0157] In some examples, the bracket 224 can include a first bracket 2241 and a second bracket 2242 that are detachably connected. Both the first bracket 2241 and the second bracket 2242 are cylindrical. The first bracket 2241 forms the atomization channel 224a. The first bracket 2241 is located in the liquid storage housing 223, and one end of the first bracket 2241 close to the first cover 221 is connected to the liquid storage housing 223. The second bracket 2242 is sleeved outside one end of the first bracket 2241 close to the second cover 222. A part of the second bracket 2242 is exposed between the liquid storage housing 223 and the second cover 222 and is respectively connected to the liquid storage housing 223 and the second cover 222. The second bracket 2242 and the first bracket 2241 jointly form the main airway 224b, and the entrance of the main airway 224b is located at the exposed part of the second bracket 2242.

[0158] The structure of the bracket 224 is relatively complex. By setting the bracket 224 as a detachable first bracket 2241 and second bracket 2242, they can be manufactured separately and then assembled, reducing the processing difficulty.

[0159] The part of the bracket 224 located inside the liquid storage housing 223 and the liquid storage housing 223 form a liquid storage chamber for storing the aerosol matrix. The side wall of the first bracket 2241 may also have a hollow structure, such as holes, openings, slits, and the hollow structure communicates with the liquid storage chamber and the atomization channel 224a, so that the aerosol matrix in the liquid storage chamber can enter the atomization channel 224a to moisten the atomization assembly 30.

[0160] As Figure 13 shown, the housing assembly of the atomizer 200 may further include an air regulating ring 225. The air regulating ring 225 can be sleeved on the part of the second bracket 2242 exposed between the liquid storage housing 223 and the second cover 222 and can rotate relative to the second bracket 2242. The air regulating ring 225 may have a flow regulating hole 225a. By rotating the air regulating ring 225, changing the area of the flow regulating hole 225a facing the inlet of the main air passage 224b, the intake air volume of the main air passage 224b during the suction process can be changed. When not in use, the flow regulating hole 225a can be completely staggered from the inlet of the main air passage 224b, and the air regulating ring 225 is used to block the inlet of the main air passage 224b to prevent foreign objects from entering the main air passage 224b.

[0161] Figure 14 and Figure 15 are schematic diagrams of the internal structure of an atomizer provided by an embodiment of the present application. Figure 14 and Figure 15 shown cross-sections are perpendicular to each other. As Figure 14 and Figure 15 shown, the atomizer 200 includes an atomization assembly 30 and any one of the housing assemblies as Figures 8 to 13 shown, and the atomization assembly 30 is located inside the second main body 22.

[0162] When connecting the atomizer 200 to the power supply 100, even if the relative rotation angle between the atomizer 200 and the power supply 100 is different each time during the connection process, the second annular groove 20a is opposite to the outlet of the air flow channel 1a of the power supply 100, and the annular cavity formed by the second annular groove 20a and the outer surface of the power supply 100 can always communicate the induction air passage 2a and the air flow channel 1a. The user does not need to pay attention to the relative rotation angle between the atomizer 200 and the power supply 100, which is convenient for the user to connect the atomizer 200 and the power supply 100 and makes the use of the aerosol generating device more convenient.

[0163] As Figure 15As shown, the atomization component 30 is located in the atomization channel 224a. The atomization component 30 may include an outer cover 31, a tubular support 32, a liquid guiding member 33, and a heating member. The outer cover 31 is sleeved outside the tubular support 32. The side walls of both the outer cover 31 and the tubular support 32 have a hollow structure, such as holes, openings, and gaps, so that the aerosol matrix can enter the inside of the tubular support 32. The tubular support 32 is installed in the atomization channel 224a. The liquid guiding member 33 is located in the tubular support 32, and the liquid guiding member 33 is used to absorb the aerosol matrix in the liquid storage chamber. The heating member may be located inside the liquid guiding member 33 and is used to heat the aerosol matrix to form an aerosol.

[0164] The material and structure of the heating member are not limited as long as it can play a heating role. Exemplarily, the heating member may include at least one of a heating mesh, a heating film, a heating wire, and a heating sheet.

[0165] The heating member may also be connected with at least two pins to facilitate power supply to the heating member.

[0166] The atomizer 200 may further include a first electrode 34, a second electrode 35, and a first insulating pad 36. Both the first electrode 34 and the second electrode 35 may be located in the second connection portion 21. The first insulating pad 36 is interposed between the first electrode 34 and the second electrode 35. The first electrode 34 and the second electrode 35 are respectively connected to the heating member.

[0167] As an example, the first electrode 34 may be a positive electrode, and the second electrode 35 may be a negative electrode.

[0168] After the atomizer 200 is connected to the power supply 100, the first electrode 34 and the second electrode 35 are respectively electrically connected to the power supply 100 to supply power to the atomization component 30.

[0169] Exemplarily, the first electrode 34 may be cylindrical and coaxially arranged with the second connection portion 21. The first insulating pad 36 may be sleeved outside the first electrode 34.

[0170] The second electrode 35 may be located on the inner wall of the second connection portion 21. Exemplarily, the second electrode 35 may be a conductive layer formed on the inner wall of the second connection portion 21, for example, a metal coating.

[0171] In some possible implementation manners, the second connection portion 21 may be a conductive member. For example, the second connection portion 21 may be a metal member, and the second electrode 35 may have the same structure as the second connection portion 21, that is, the second connection portion 21 is reused as the second electrode 35.

[0172] As Figure 15As shown, the atomizer 200 may further include a transition electrode 37 and a second insulating pad 38, both of which are cylindrical. The second insulating pad 38 may be sleeved outside the transition electrode 37, and the second insulating pad 38 is inserted into the end of the tubular bracket 32 to separate the tubular bracket 32 and the transition electrode 37. The first electrode 34 may be located on the side of the transition electrode 37 away from the tubular bracket 32 and in contact with the transition electrode 37. The transition electrode 37 is used to connect to the heating element. Exemplarily, at least one pin of the heating element may be connected to the transition electrode 37, and at least another pin of the heating element may be connected to the second electrode 35.

[0173] The tubular bracket 32 may be a metal part, which can improve the structural strength of the tubular bracket 32 and also facilitate heat conduction of the atomization assembly 30.

[0174] Figure 16 is a schematic structural diagram of an aerosol generating device provided by an embodiment of the present application, as Figure 16 shown, the aerosol generating device includes an atomizer 200 and a power source 100 for supplying power to the atomizer 200.

[0175] The atomizer 200 may be Figure 14 or Figure 15 the atomizer shown; alternatively, the power source 100 is Figure 7 the power source shown.

[0176] In some examples, the atomizer 200 is Figure 14 or Figure 15 the atomizer shown, and the power source 100 is Figure 7 the power source shown.
