[0045] Please see Figures 1 to 5 This application provides an aerosol generating device 100, including: a main body 1 and a cleaning cover 2.

[0046] In this embodiment, a heating chamber 11 is provided in the main body 1 for containing and heating the aerosol-generating article 200; a receiving cavity 12 is also provided in the main body 1, and the receiving cavity 12 is in communication with the heating chamber 11. At least a portion of the cleaning cover 2 is contained in the receiving cavity 12, and the cleaning cover 2 is configured to be connected to or separated from the main body 1 for sealing at least a portion of the opening of the receiving cavity 12.

[0047] Furthermore, the cleaning cover 2 includes an elastic arm 21, on which a first fixing member 22 is provided. The main body 1 is provided with a second fixing member 13 corresponding to the first fixing member 22. The first fixing member 22 is configured to engage or disengage with the second fixing member 13. The elastic arm 21 on the cleaning cover 2 allows for some elastic deformation adjustment of the first fixing member 22 when engaging with the second fixing member 13, preventing mutual wear caused by a rigid fit between the two members and thus reducing their service life. This reduces wear during the installation and removal of the cleaning cover 2, extending the service life of the cleaning cover 2 and the entire aerosol generating device 100.

[0048] When the first fixing member 22 and the second fixing member 13 are engaged, the cleaning cover 2 is fixed to the main body 1. When the first fixing member 22 and the second fixing member 13 are separated, the cleaning cover 2 can be removed from the main body 1, so that cleaning tools can be used to clean the heating chamber 11 through the receiving cavity 12.

[0049] Optionally, aerosol generating article 200 refers to an article comprising an aerosol generating matrix intended to be heated rather than burned to release volatile compounds that can form aerosols. When heated, the aerosol generating matrix releases volatile compounds that can form aerosols. Aerosols formed by heating the aerosol generating matrix may contain fewer known hazardous components than aerosols generated by combustion or pyrolytic degradation of the aerosol generating matrix. Aerosol generating article 200 may be disposable or reusable. The aerosol generating matrix may be a solid aerosol generating matrix. Alternatively, the aerosol generating matrix may include solid and liquid components. The aerosol generating matrix may include tobacco and / or non-tobacco materials; or the aerosol generating matrix may include tobacco-containing materials and / or non-tobacco materials; wherein the tobacco-containing materials contain volatile tobacco flavor compounds that are released from the matrix upon heating.

[0050] In some embodiments, please refer to Figures 5 to 8 The first fixing member 22 can be one of a slot and a buckle, and the second fixing member 13 can be the other of a slot and a buckle. The slot is configured to rotate under external actuation and engage or disengage with the buckle. When the slot is disengaged from the buckle, the cleaning cover 2 is fixed to the main body 1. When the slot is disengaged from the buckle, the cleaning cover 2 can be removed from the main body 1, so that cleaning tools can be used to clean the heating chamber 11 through the receiving cavity 12. Exemplarily, the slot is provided on the elastic arm 21 of the cleaning cover 2, and the buckle is provided on the main body 1. When the slot and the buckle engage, the presence of the elastic arm 21 allows the slot to undergo a certain elastic deformation when engaging with the buckle, thereby avoiding wear caused by a rigid engagement between the slot and the buckle.

[0051] In some embodiments, please refer to Figure 5 , Figure 6 and Figure 7 The cleaning cover 2 may include an extension arm 23, the extension direction of which is different from that of the elastic arm 21. One end of the extension arm 23 is connected to the elastic arm 21, and a slot is provided at the end of the extension arm 23 away from the elastic arm 21. A buckle is provided on the main body 1 corresponding to the slot. For example, the cleaning cover 2 may have elastic arms 21 on both sides corresponding to the extension direction of the main body 1, and an extension arm 23 is provided in a direction perpendicular to the elastic arm 21, with the extension directions of the two extension arms 23 being opposite. A groove is provided at the end of the extension arm 23 away from the elastic arm 21, so that the groove can engage with the buckle on the main body 1 in a direction perpendicular to the main body 1.

[0052] In some embodiments, please refer to Figure 7 The cleaning cover 2 may also include a reinforcing rib 24, one end of which is connected to the elastic arm 21 and the other end to the extension arm 23. The reinforcing rib 24 enhances the strength and stability of the extension arm 23, preventing damage during repeated use.

[0053] In some embodiments, please refer to Figure 7 and Figure 8 A first limiting part 41 may be provided on the inner wall of the receiving cavity 12 to prevent the slot from rotating. The first limiting part 41 can limit the rotation range of the slot and enhance the stability of the engagement between the slot and the buckle. For example, the first limiting part 41 may be a protrusion provided on the inner wall of the receiving cavity 12, which at least partially overlaps with the buckle along the extension direction of the main body part 1.

[0054] In some embodiments, please refer to Figure 7 and Figure 8 A second limiting part 42 may be provided on the inner wall of the receiving cavity 12. The second limiting part 42 is located on the side of the buckle away from the heating cavity 11. The second limiting part 42 can support the free end of the extension arm 23 and is used to limit the extension arm 23 to prevent the cleaning cover 2 from falling out of the receiving cavity 12.

[0055] Further, please refer to Figure 7 and Figure 8 The extension arm 23 is configured to rotate along the side of the second limiting portion 42 near the latch, thereby engaging the latch groove with the latch. Exemplarily, the second limiting portion 42 can be a protrusion disposed on the inner wall of the receiving cavity 12 and perpendicular to the extending direction of the main body portion 1. One end of the protrusion can be connected to the first limiting portion 41. The extension arm 23 rotates along the side of the protrusion near the latch until it abuts against the first limiting portion 41, at which point the latch groove engages with the latch. The second limiting portion 42 can be perpendicular to the first limiting portion 42.

[0056] In some embodiments, please refer to Figure 6 , Figure 7 and Figure 8 An extension 43 and a guide 44 may also be provided on the inner wall of the receiving cavity 12. The guide 44 is used to connect the extension 43 and the second limiting part 42. The extension 43 and the guide 44 are used to guide the extension arm 23 to slide towards the side of the second limiting part 42 near the buckle. By providing the extension 43 and the guide 44, the extension arm 23 can be guided to quickly and accurately engage with the second limiting part 42, thereby improving the engagement speed and accuracy of the slot and the buckle.

[0057] In some embodiments, please refer to Figure 4 and Figure 8 The main body 1 includes a housing assembly 3 and a bottom cover 4. The bottom cover 4 is located at the opposite end to the opening of the heating chamber 11 and is used to block at least a portion of the housing assembly 3 away from the opening of the heating chamber 11. At least a portion of the receiving cavity 12 is formed by the bottom cover 4. Exemplarily, the opening of the receiving cavity 12 may be formed on the bottom cover 4, and the second fastener 13 may be disposed on the bottom cover 4.

[0058] In other embodiments, the second fastener 13 may also be disposed on the housing assembly 3.

[0059] In some embodiments, please refer to Figure 4 , Figure 8 and Figure 9 The bottom cover 4 is provided with a wall 45 extending toward the heating chamber 11. The wall 45 can be configured to enclose at least a part of the receiving chamber 12. The second fixing member 13 can be provided on the inner wall of the wall 45.

[0060] Further, please refer to Figure 4 , Figure 8 and Figure 9 A third fixing member 46 may also be provided on the wall 45, and a fourth fixing member 321 corresponding to the third fixing member 46 may be provided on the outer shell assembly 3. The third fixing member 46 and the fourth fixing member 321 are connected. Exemplarily, the outer shell assembly 3 may include a shell 31 and a bracket 32. The bracket 32 ​​is disposed inside the shell 31. The third fixing member 46 may be provided on both sides of the end of the wall 45 near the heating chamber 11. The bracket 32 ​​may be provided with a fourth fixing member 321 corresponding to the third fixing member 46. One of the third fixing member 46 and the fourth fixing member 321 may be a buckle and the other may be a slot. For example, the third fixing member 46 is a buckle and the fourth fixing member 321 is a slot.

[0061] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4The opening direction of the receiving cavity 12 can be opposite to that of the opening direction of the heating cavity 11. Therefore, when the cleaning cover 2 inside the receiving cavity 12 is removed, the heating cavity 11 can be cleaned more conveniently through the receiving cavity 12.

[0062] In some embodiments, please refer to Figure 4 and Figure 10 The opening edge of the receiving cavity 12 may be provided with a first marking element 14, and the cleaning cover 2 is provided with a second marking element 26. When the second marking element 26 is aligned with the first marking element 14, it can guide the cleaning cover 2 to be inserted into the receiving cavity 12, thereby enabling more efficient and faster assembly between the cleaning cover 2 and the main body 1.

[0063] For example, when the cleaning cover 2 is cylindrical and the cross-section of the receiving cavity 12 is also circular, there is no reference for the assembly between the cleaning cover 2 and the main body 1, making it difficult to quickly achieve assembly. Consequently, it is also difficult to achieve accurate matching between the first fixing member 22 and the second fixing member 13. Therefore, a first marking member 14 can be provided at the opening edge of the receiving cavity 12 of the bottom cover 4 of the main body 1. At the same time, a second marking member 26 corresponding to the first marking member 14 can be provided on the cleaning cover 2. When the positions of the first marking member 14 and the second marking member 26 are aligned, the cleaning cover 2 can be inserted into the receiving cavity 12 from that position. After the cleaning cover 2 is inserted into the receiving cavity 12, the extension arm 23 on the cleaning cover 2 can slide further into the receiving cavity 12 under the guidance of the extension 43 on the inner wall of the receiving cavity 12. When it slides to the guide 44, it can slide down to the side of the second limiting part 42 near the second fixing member 13 under the guidance of the guide 44. The cleaning cover 2 can be rotated at a certain angle relative to the main body part 1 under external actuation to realize the cooperation between the first fixing member 22 and the second fixing member 13 at the end of the extension arm 23.

[0064] In some embodiments, please refer to Figure 4 The aerosol generating device 100 may further include a heating component 6 and a base 5. The base 5 can be mounted on a bracket 32 ​​and can be a barrel-shaped structure with both ends open, used to connect the wall 45 of the bottom cover 4 and the heating chamber 11, and to support the heating component 6. The heating chamber 11 can be located inside the heating component 6. The receiving cavity 12 can be formed by the base 5 and the wall 45 of the bottom cover 4.

[0065] Further, please refer to Figure 4The aerosol generating device 100 may further include a support member 7. One end of the support member 7 is connected to the end of the cleaning cover 2 near the heating chamber 11, and the other end of the support member 7 can be used for the end of a cigarette inserted into the heating chamber 11. The support member 7 is provided with a clearance structure that connects the interior of the cleaning cover 2 and the heating chamber 11. The support member 7 can be any non-solid structure. Furthermore, a vent hole 25 may be provided at the end of the cleaning cover 2 away from the heating chamber 11, and this vent hole 25 can communicate with the heating chamber 11. Thus, when the user inhales the aerosol generating product 200, the vent hole 25 of the bottom cover 4, the clearance structure on the support member 7, and the heating chamber 11 can form a passage.

[0066] Further, please refer to Figure 4 The aerosol generating device 100 also includes a battery 8, which can provide power to the heating component 6 and other components inside the aerosol generating device 100.

[0067] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
