Technical field

[0003] The present invention relates to the technical field of electronic atomization, and in particular to an aerosol generating device. [Background Technology]

[0004] An aerosol-generating device is used to heat and atomize an aerosol-generating product to form an aerosol for inhalation. An aerosol-generating device typically comprises a main body and a cover. The main body has a receiving cavity and an insertion hole communicating with the receiving cavity, through which the aerosol-generating product is inserted and removed. The cover covers the insertion hole, preventing dust and debris, odors, and the like from escaping the receiving cavity.

[0005] However, the cover of the existing aerosol generating device needs to be slid manually, and the user may easily forget to slide the cover after use, and the cover loses its designed function.

[0006] [Summary of the invention]

[0007] The aerosol generating device provided in the present application is intended to solve the problem that the cover of the existing aerosol generating device needs to be manually slid, and the user easily forgets to slide the cover during use.

[0008] To solve the above technical problems, a technical solution adopted in this application is to provide an aerosol generating device, which includes:

[0009] a housing assembly having an insertion hole for inserting the aerosol generating article;

[0010] a cover body slidably connected to the housing assembly; and the cover body can be configured to a first position to cover the insertion hole; or configured to a second position to expose at least a portion of the insertion hole;

[0012] In which, the cover body forms an abutment surface on the side facing the insertion hole, and the abutment surface is arranged at an angle. During the process of inserting the aerosol generating product into the insertion hole, the abutment surface is acted upon by a driving force, so that the cover body is configured from the first position to the second position; during the process of pulling the aerosol generating product out of the insertion hole, the cover body is configured to the first position under the drive of the elastic member.

[0020] In one embodiment, the cover includes a first cover and a second cover that are arranged opposite to each other;

[0021] The elastic member includes a first elastic member and a second elastic member, the first elastic member is arranged on a sliding path of the first cover relative to the housing assembly, and abuts against the first cover and the housing assembly respectively; the second elastic member is arranged on a sliding path of the second cover relative to the housing assembly, and abuts against the second cover and the housing assembly respectively;

[0022] Wherein, the opposite side surfaces of the first cover body and the second cover body both have abutment surfaces; when the cover body is configured to the first position, the first cover body and the second cover body cooperate to cover the insertion hole.

[0023] In one embodiment, the abutting surface of the first cover body and the abutting surface of the second cover body are symmetrically arranged planes.

[0024] In one embodiment, the housing assembly comprises:

[0025] A first housing assembly includes a first annular side wall and a first top wall; the first top wall has a first insertion opening;

[0026] A second housing assembly includes a second annular side wall and a second top wall; the second top wall has a second insertion opening corresponding to the first insertion opening;

[0027] The second shell component is sleeved on one end of the first shell component, and the second top wall and the first top wall are spaced apart to form a mounting groove; the cover body and the elastic member are arranged in the mounting groove.

[0028] In one embodiment, the cover body has a first card slot on one side surface facing the second top wall; the sensing component is embedded in the card slot; and / or the cover body has a second card slot on one side surface facing the first annular side wall, and a limiting column is provided in the second card slot; the end of the elastic component abutting against the cover body is embedded in the second card slot and is sleeved on the outside of the limiting column.

[0029] In one embodiment, the housing assembly further includes a limiting frame, which is disposed in the mounting groove and surrounds the cover in a circumferential direction.

[0030] Among them, one end of the elastic member facing away from the cover body abuts against the limit frame; and one of the limit frame and the cover body has a limit groove, and the other has a limit protrusion, the limit protrusion is embedded in the limit groove, and can slide along the extension direction of the limit groove.

[0031] In one embodiment, the shell assembly further includes: an inner shell, disposed in the first shell assembly, and having a receiving groove; the notch of the receiving groove is opposite to the insertion hole, so that the aerosol generating product enters the receiving groove after passing through the insertion hole.

[0033] Wherein, one side surface of the first cover body has an abutting surface; when the cover body is configured to the first position, the first cover body covers the entire insertion hole.

[0034] Beneficial effects of the present application: Different from the prior art, the present application provides an aerosol generating device, which includes a housing assembly, a cover, and an elastic member. The housing assembly has an insertion hole for inserting an aerosol generating product; the cover is slidably connected to the housing assembly and can be configured to a first position to block the insertion hole, thereby preventing external dust, particulate matter, etc. from entering the interior of the aerosol generating device through the insertion hole and preventing odors within the aerosol generating device or residues of the aerosol generating product from overflowing through the insertion hole. Alternatively, the cover can be configured to a second position to expose at least a portion of the insertion hole, thereby allowing the aerosol generating product to be inserted into the insertion hole. The elastic member is disposed on a sliding path of the cover relative to the housing assembly and abuts the cover and the housing assembly, respectively. When the cover is positioned in the second position, the elastic member is in a compressed state. Furthermore, the cover forms an abutting surface on the side facing the insertion hole, the abutting surface being inclined. During the insertion of the aerosol-generating product into the insertion hole, the abutting surface is acted upon by a driving force, causing the cover to be positioned from the first position to the second position. During the removal of the aerosol-generating product from the insertion hole, the cover is driven by the elastic member to be positioned in the first position. Thus, when the aerosol-generating product needs to be inserted, the aerosol-generating product can apply a force to the abutting surface of the cover, causing the abutting surface of the cover to be squeezed and positioned from the first position to the second position, thereby enabling the insertion of the aerosol-generating product. At this time, the elastic member is squeezed and in a compressed state. If the aerosol-generating product is removed, the force acting on the abutting surface of the cover disappears, and the cover, driven by the elastic restoring force of the elastic member, is repositioned from the second position to the first position to cover the insertion hole. This process allows the user to cover the insertion hole without manually operating the cover again, thus preventing the insertion hole from being completely exposed to the outside atmosphere due to the user forgetting to slide the cover. Furthermore, by compressing the elastic member when the cover is in the second position, the elastic restoring force of the elastic member allows the cover to securely hold the aerosol-generating product. Thus, during inhalation, the aerosol-generating product is prevented from being easily removed by the user due to the clamping force of the cover.

[0049] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0050] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0051] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the overall structure of an aerosol-generating article provided in one embodiment of the present application, inserted into an aerosol-generating device. Figure 2 is a cross-sectional view taken along the AA axis of the structure shown in Figure 1 provided in one embodiment of the present application. In this embodiment, an aerosol-generating device 2 is provided. The aerosol-generating device 2 is used to accommodate and atomize the aerosol-generating article 1 to form an aerosol for inhalation by the user. The aerosol-generating device 2 can be used in fields such as medical aerosolization, recreational inhalation, and cosmetic aerosolization. The aerosol-generating article 1 generally includes a filter segment, a connecting segment, and a matrix segment, which are connected in sequence. The matrix segment includes an aerosol-generating matrix. The aerosol-generating device 2 is used to heat the aerosol-generating matrix to form an aerosol when powered. The filter segment is used to filter the aerosol. The connecting segment is used to reduce the temperature of the aerosol generated by atomization to prevent burns to the mouth. The other specific structures and functions of the filter segment, connecting segment, and matrix segment are the same or similar to those of existing aerosol-generating products and will not be further described here.

[0052] 2 to 4 , FIG3 is a schematic structural diagram of the aerosol generating device in FIG2 without an aerosol generating article inserted therein; FIG4 is an enlarged view of point P in FIG3 . The aerosol generating device 2 includes a housing assembly 21 , a cover 24 , and an elastic member 25 .

[0053] 4 , the housing assembly 21 has an insertion hole 22 , and the aerosol generating article 1 is inserted into the housing assembly 21 through the insertion hole 22 . Specifically, the housing assembly 21 includes a first housing assembly 211 , a second housing assembly 212 and an inner shell 23 .

[0054] The first housing assembly 211 includes a first annular sidewall 2111 and a first top wall 2112. The first top wall 2112 defines a first insertion opening 221. The second housing assembly 212 includes a second annular sidewall 2121 and a second top wall 2122. The second top wall 2122 defines a second insertion opening 222 corresponding to the first insertion opening 221. The aerosol-generating article 1 sequentially passes through the second insertion opening 222 and the first insertion opening 221 and enters the receiving groove 231. In one embodiment, the second housing assembly 212 is sleeved onto one end of the first housing assembly 211. The second top wall 2122 is spaced apart from the first top wall 2112 to form a mounting groove 213. The cover 24 and the elastic member 25 are disposed within the mounting groove 213. The inner housing 23 defines a receiving groove 231. The notch of the receiving groove 231 opposes the insertion hole 22. The aerosol-generating article 1 enters the receiving groove 231 after passing through the insertion hole 22.

[0055] The aerosol-generating device 2 also includes a heating assembly, disposed within the housing assembly 21, for heating and atomizing the aerosol-generating article 1 to form an aerosol. The heating assembly can employ electromagnetic heating or resistive heating; alternatively, it can employ insertion heating or surround heating. In one embodiment, the heating assembly includes a heater 28, at least a portion of which extends into the receiving groove 231, is adapted to receive the aerosol-generating article 1, and heats the aerosol-generating article 1 when powered.

[0056] The cover 24 can be in a sheet or block shape. The cover 24 is large enough to cover the insertion hole 22. The cover 24 is slidably connected to the housing assembly 21 and can be configured to different first and second positions. Optionally, the sliding connection between the cover 24 and the housing assembly 21 can be achieved by providing a slideway; alternatively, the sliding connection can be achieved by providing a sliding space within the housing assembly 21 and positioning the cover 24 within the sliding space. When the cover 24 is configured in the first position, it blocks the insertion opening, thereby preventing external dust, particulate matter, etc. from entering the interior of the aerosol generating device 2 through the insertion hole 22 and preventing odors within the aerosol generating device 2 or residue from the aerosol generating product 1 from escaping through the insertion hole 22. When the cover 24 is configured in the second position, the cover 24 is away from the insertion hole 22 and exposes at least a portion of the insertion hole 22 along the insertion direction Y of the aerosol generating product 1, thereby allowing the aerosol generating product 1 to be inserted into the insertion hole 22.

[0057] The elastic member 25 is disposed along the sliding path of the cover 24 relative to the housing assembly 21 and abuts against the cover 24 and the housing assembly 21, respectively. When the cover 24 is in the second position, the elastic member 25 is in a compressed state. Thus, when an external force acting on the cover 24 in the direction opposite to the elastic restoring force of the elastic member 25 is less than the elastic restoring force, the cover 24 can automatically be moved from the second position to the first position, driven by the elastic restoring force of the elastic member 25, to cover the insertion hole 22. This process allows the user to cover the insertion hole 22 without manually operating the cover 24 again, thus preventing the insertion hole 22 from being completely exposed to the outside atmosphere due to the user forgetting to slide the cover 24. Furthermore, by keeping the elastic member 25 in a compressed state when the cover 24 is in the second position, the elastic restoring force of the elastic member 25 allows the cover 24 to securely hold the aerosol-generating article 1. This prevents the aerosol-generating article 1 from being easily dislodged by the user during inhalation due to the gripping force of the cover 24.

[0058] The elastic member 25 may be a spring, a spring sheet or a coil spring.

[0059] In one specific embodiment, referring to FIG5 , FIG5 is a schematic diagram of the overall structure of the cover provided by one embodiment of the present application; the cover 24 has a second retaining groove 244 on one side of the surface facing the first annular side wall 2111, and a retaining post 245 is disposed within the second retaining groove 244. The end of the elastic member 25 that contacts the cover 24 is embedded in the second retaining groove 244 and is sleeved around the retaining post 245. In this way, the elastic member 25 can be retained on the retaining post 245, reducing the risk of the elastic member 25 being separated from the cover 24 during the extrusion process.

[0060] Furthermore, in conjunction with Figures 6 and 7, and in conjunction with Figure 2, Figures 6 and 7 are schematic diagrams of the process of inserting the aerosol-generating article into the aerosol-generating device. The side 246 of the cover 24 facing the insertion hole 22 forms an abutment surface; the abutment surface is inclined relative to the insertion direction Y of the aerosol-generating article 1; the abutment surface can be an inclined plane or a curved surface, for example, an inclined surface or an arc surface inclined relative to the insertion direction Y of the aerosol-generating article 1, and the arc surface can be a concave or convex arc surface. Thus, when a vertical downward force (i.e., the insertion direction Y of the aerosol-generating article 1) is applied to the abutment surface of the cover 24, according to the principle of force decomposition, the vertical downward force will press the cover 24 toward both sides of the insertion hole 22, so that the cover 24 can be configured from the first position to the second position.

[0061] During the insertion of the aerosol-generating product 1 into the insertion hole 22, the aerosol-generating product 1 abuts the abutting surface. As a vertically downward force (i.e., in the insertion direction Y of the aerosol-generating product 1) continues to be applied to the abutting surface of the cover 24, this vertically downward force acts on the abutting surface according to the force decomposition principle. The abutting surface of the cover 24 is acted upon by a force component in the lateral direction X decomposed from the vertical direction, causing the cover 24 to be moved from the first position to the second position, thereby enabling the insertion of the aerosol-generating product 1. At this time, the elastic member 25 is squeezed and compressed. During the removal of the aerosol-generating product 1 from the insertion hole 22, the force acting on the abutting surface of the cover 24 disappears, and the cover 24, driven by the elastic restoring force of the elastic member 25, is moved from the second position to the first position, thereby obstructing the insertion hole 22.

[0062] In one specific embodiment, when the external force acting on the abutting surface is greater than or equal to a threshold value, the component of the external force in the transverse direction X is greater than or equal to the elastic restoring force of the elastic member 25. In this case, the cover 24 is configured from the first position to the second position. When the external force is less than the threshold value, the component of the external force in the transverse direction X is less than the elastic restoring force of the elastic member 25. In this case, the cover 24 is configured from the second position to the first position under the drive of the elastic member 25. For example, when the cover 24 is in the first position, the force exerted on the cover 24 by the brush or cleaning rod is equal to or less than the threshold value. In this way, the cover 24 can be prevented from being accidentally opened by the brush or cleaning rod.

[0063] The mechanical structure formed by the cover 24, housing assembly 21, and elastic member 25 is such that, when the aerosol-generating product 1 needs to be inserted into the aerosol-generating device 2, the aerosol-generating product 1 can apply a force to the abutting surface of the cover 24, causing the abutting surface of the cover 24 to be squeezed and configured from the first position to the second position, thereby enabling the insertion of the aerosol-generating product 1. At this time, the elastic member 25 is squeezed and compressed. If the aerosol-generating product 1 is removed, the force acting on the abutting surface of the cover 24 disappears, and the cover 24, driven by the elastic restoring force of the elastic member 25, is configured from the second position to the first position to cover the insertion hole 22. This process allows the user to cover the insertion hole 22 without manually operating the cover 24 again, thus avoiding the situation where the user forgets to slide the cover 24, causing the insertion hole 22 to be completely exposed to the outside atmosphere. At the same time, by compressing the elastic member 25 when the cover 24 is in the second position, the cover 24 can firmly hold the aerosol-generating product 1 due to the elastic restoring force of the elastic member 25. Thus, during inhalation, the aerosol-generating product 1 is prevented from being easily removed by the user due to the clamping force of the cover 24. Furthermore, by setting a threshold, the risk of the cover 24 being opened due to misoperation can be reduced.

[0064] In one embodiment, as shown in FIG4 , the aerosol generating device 2 further includes a to-be-sensed element 26 , a sensing element 27 and a control circuit.

[0065] The sensing member 26 is disposed on the cover 24 and slides with the cover 24. In one embodiment, as shown in FIG5 , the cover 24 has a first slot 243 on one side of the cover 24 facing the second top wall 2122. The sensing member 26 is embedded in the slot so that, as the cover 24 slides, the sidewall of the first slot 243 drives the sensing member 26 to slide with it. The sensing member 26 can be directly embedded in the first slot 243, or it can be secured by adhesive, screws, or other means.

[0066] The sensing member 27 is provided in the housing assembly 21 and is used to sense the member to be sensed 26. The control circuit is electrically connected to the sensing member 27. In conjunction with Figures 2 and 4, when the cover body 24 is configured to the first position and the second position, the straight-line distance between the member to be sensed 26 and the sensing member 27 is different, and the sensing member 27 senses different signals or cannot sense a signal at one of the positions. Specifically, when the cover body 24 is configured to the first position, the sensing member 27 senses the member to be sensed 26 and generates a first signal, and the control circuit responds to the first signal and controls the heating component to be powered off, so that the heating component stops working. When the cover body 24 is configured to the second position, the sensing member 27 senses the member to be sensed 26 and generates a second signal, and the control circuit responds to the second signal and controls the heating component to be powered on, and the heating component starts working to heat and atomize the aerosol generating product 1 and generate an aerosol.

[0067] It can be understood that the first signal and the second signal are two different signals; or, one of the first signal and the second signal may be no signal.

[0068] Specifically, in one embodiment, the sensing element 26 comprises a magnet, and the sensing element 27 comprises a Hall effect device. When the aerosol-generating article 1 is inserted into the insertion hole 22, the magnet is pushed to the second position along with the cover 24. The magnet on the cover 24 approaches the Hall effect device. The Hall effect device senses the magnetic field around the magnet and generates a second signal. The control circuit, in response to the second signal, controls the heating element to be energized, causing the heating element to begin operating, heating the aerosol-generating article 1 to generate aerosol. When the aerosol-generating article 1 is removed from the insertion hole 22, the magnet is configured to the first position along with the cover 24. The Hall effect device senses the magnet's movement away from or disappearance, and generates a first signal. The control circuit, in response to the first signal, controls the heating element to be de-energized, causing the heating element to cease operation.

[0069] Those skilled in the art will understand that, during the process of inserting or removing the aerosol generating article 1 into the insertion hole 22, the first conductor moves along with the cover 24, and the relative area between the first conductor and the second conductor gradually increases or decreases. According to the capacitance formula, the capacitance between the first conductor and the second conductor will gradually change; therefore, in another embodiment, whether the second signal is generated can be determined by detecting the capacitance change between the first conductor and the second conductor.

[0070] Specifically, the sensing element 26 includes a first conductor, and the sensing element 27 includes a second conductor and a capacitance detection device. The capacitance detection device is electrically connected to the first conductor and the second conductor, respectively, and is configured to detect the capacitance between the first conductor and the second conductor, generating a second signal when the capacitance is not less than a capacitance threshold, and generating a first signal when the capacitance is less than the capacitance threshold. Specifically, when the aerosol-generating article 1 is inserted into the insertion hole 22, the first conductor is pushed to the second position along with the cover 24, and the relative area between the first conductor and the second conductor gradually increases. According to the capacitance formula, under the condition that other parameters remain constant, the capacitance between the first conductor and the second conductor also gradually increases. When the capacitance is not less than the capacitance threshold, the capacitance detection device generates a second signal. In response to the second signal, the control circuit controls the heating component to energize, causing the heating component to begin operating and heat the aerosol-generating article 1 to generate aerosol. During the process of pulling the aerosol generating article 1 out of the insertion hole 22, the relative area between the first conductor and the second conductor gradually decreases. According to the capacitance formula, when other parameters remain constant, the capacitance between the first conductor and the second conductor also gradually decreases. When the capacitance is less than the capacitance threshold, the capacitance detection device generates a first signal, and the control circuit responds to the first signal and controls the heating component to cut off power, and the heating component stops working.

[0071] In one embodiment, as shown in Figure 4, the cover body 24 includes a first cover body 241 and a second cover body 242 arranged opposite to each other; the elastic member 25 includes a first elastic member 251 and a second elastic member 252, the first elastic member 251 is arranged on the sliding path of the first cover body 241 relative to the shell assembly 21, and abuts against the first cover body 241 and the shell assembly 21 respectively; the second elastic member 252 is arranged on the sliding path of the second cover body 242 relative to the shell assembly 21, and abuts against the second cover body 242 and the shell assembly 21 respectively.

[0072] In one embodiment, the opposing sides 246 of the first cover 241 and the second cover 242 each have an abutment surface. When the cover 24 is configured to the first position, the first cover 241 and the second cover 242 cooperate to cover the insertion hole 22; that is, the first cover 241 covers a portion of the insertion hole 22, and the second cover 242 covers the remaining portion of the insertion hole 22. When the aerosol-generating article 1 is to be inserted, referring to FIG7 and FIG2 , the aerosol-generating article 1 abuts against the abutment surfaces of the first cover 241 and the second cover 242, respectively, and applies a force to these two abutment surfaces. According to the principle of force decomposition, this force generates a component force in the transverse direction X on both sides of the insertion hole 22, thereby driving the first cover 241 and the second cover 242 to move in opposite directions and be configured from the first position to the second position, thereby exposing the insertion hole 22 through the first cover 241 and the second cover 242. During this process, the first elastic member 251 is gradually compressed by the first cover 241 and is in a compressed state; the second elastic member 252 is also gradually compressed by the second cover 242 and is in a compressed state.

[0073] After the aerosol generating product 1 is pulled out, the force acting on the first cover body 241 and the second cover body 242 disappears, and the first cover body 241 in the second position moves toward the center axis M of the insertion hole 22 under the action of the elastic restoring force of the first elastic member 251, and the second cover body 242 in the second position also moves toward the center axis M of the insertion hole 22 under the action of the elastic restoring force of the second elastic member 252, until the first cover body 241 and the second cover body 242 collide with each other and cooperate to cover the insertion hole 22, that is, the first cover body 241 and the second cover body 242 are configured to the first position.

[0074] Among them, when the first cover body 241 and the second cover body 242 are configured to the first position, the first elastic member 251 and / or the second elastic member 252 are still in an elastically compressed state; in this way, the first cover body 241 and the second cover body 242 can be driven to fit tightly together through the elastic force of the two, reducing the risk of the cover body 24 being opened due to misoperation.

[0075] Specifically, the abutting surface of the first cover 241 and the abutting surface of the second cover 242 are symmetrically arranged planes. Of course, the abutting surfaces can also be curved surfaces; the abutting surfaces of the first cover 241 and the second cover 242 can also be asymmetrical planes or curved surfaces. For example, the abutting surface of the first cover 241 and the abutting surface of the second cover 242 can have different inclination angles.

[0076] In conjunction with Figures 4, 8, and 9, Figure 8 is a schematic diagram of the decomposition of the aerosol generating device provided in one embodiment of the present application; Figure 9 is a schematic diagram of the structure of the aerosol generating device provided in one embodiment of the present application without the first shell assembly. In one embodiment, the shell assembly 21 further includes a limit frame 29, which is disposed in the mounting groove 213 and is arranged around the circumferential direction of the cover body 24. The end of the elastic member 25 facing away from the cover body 24 abuts against the limit frame 29, and one of the limit frame 29 and the cover body 24 has a limit groove, and the other has a limit protrusion. The limit protrusion can be embedded in the limit groove and can slide along the extension direction of the limit groove to guide the movement of the cover body 24 between the first position and the second position.

[0077] Specifically, the limiting frame 29 may be a rectangular frame. The first cover 241 and the second cover 242 move along the transverse direction X of the aerosol generating device 2 to be configured between the first position and the second position. The first cover 241 and the second cover 242 have steps extending along the transverse direction X of the aerosol generating device 2 to define a limiting groove. The two side walls of the rectangular frame extending along the transverse direction X of the aerosol generating device 2 protrude toward the cover 24 and overlap the steps of the first cover 241 and the second cover 242 to define a sliding path for the first cover 241 and the second cover 242.

[0078] As shown in Figures 10 and 11, Figure 10 is a cross-sectional view taken along the AA line of the structure shown in Figure 1, provided in another embodiment of the present application; Figure 11 is a schematic diagram of the structure of the aerosol generating device in Figure 10 without an aerosol-generating article inserted therein; and Figure 12 is a schematic diagram of a disassembled version of the aerosol generating device shown in Figure 10. In yet another embodiment, another aerosol generating device 2' is provided. Unlike the aerosol generating device 2 provided in the aforementioned embodiment, this aerosol generating device 2' has only one cover 24 and one elastic member 25. Specifically, the cover 24 includes a first cover 241'; the elastic member 25 includes a first elastic member 251'. The first elastic member 251' is disposed along the sliding path of the first cover 241' relative to the housing assembly 21 and abuts against the first cover 241' and the housing assembly 21, respectively. As shown in Figure 11, when the cover 24 is configured in the first position, the first cover 241' completely obscures the insertion hole 22. As shown in FIG10 , when the cover 24 is configured in the second position, along the lateral direction X of the aerosol generating device 2 ′, the first cover 241 ′ is away from the insertion hole 22 and exposes at least a portion of the insertion hole 22. Specifically, when the cover 24 is configured in the second position, the cover 24 exposes the entire insertion hole 22.

[0079] It can be understood that in this embodiment, the cover body 24 is an integrally molded structure, and the specific structure of the cover body 24 is similar to the structure of the above-mentioned first cover body 241 or the second cover body 242. The size of the cover body 24 of this embodiment is larger than the size of the first cover body 241 or the second cover body 242 provided in the above-mentioned first embodiment.

[0080] Of course, the aerosol generating device 2 also includes components such as a power supply, a circuit board, a seal, and a fixing part. The specific structure and function of these components are the same or similar to the specific structure and function of the relevant components in the existing aerosol generating system, and can achieve the same or similar technical effects. For details, please refer to the existing technology.

Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
