The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0053] To facilitate the cleaning of the interior of the heating chamber and improve the user experience, the present embodiment provides an aerosol generating device, which will be described in detail below in combination with Figures 1 to 7 the specific content of this embodiment. It should be noted that the first direction mentioned in this embodiment is Figure 3 the X direction in Figure 3 and the second direction mentioned in this embodiment is

[0054] As Figures 1 to 5 shown, the aerosol generating device in this embodiment includes a main body part 1, a cover body 2, and an operating member 4. The main body part 1 includes at least part of a heating assembly 3. The cover body 2 and the main body part 1 jointly define a heating chamber 33 for accommodating an aerosol generating article. The cover body 2 is movably connected to the main body part 1 to open or close the heating chamber 33. The operating member 4 is connected to the main body part 1. The operating member 4 has a first state and a second state. When the operating member 4 is in the first state, the operating member 4 is configured to keep the cover body 2 in a position closing the heating chamber 33; when the operating member 4 is in the second state, the cover body 2 is adapted to switch to a position opening the heating chamber 33.

[0055] For the aerosol generating device provided by the embodiment, the main body part 1 includes at least part of the heating assembly 3. The cover body 2 and the main body part 1 jointly define a heating chamber 33. The operating member 4 has a first state and a second state. When the operating member 4 is in the first state, the cover body 2 is in a position closing the heating chamber 33, so that the aerosol generating article placed in the heating chamber 33 can be heated. When it is necessary to clean the interior of the heating chamber 33, the operating member 4 can be made to be in the second state, and the cover body 2 switches to a position opening the heating chamber 33, which is convenient for cleaning the interior of the heating chamber 33 and improves the user experience.

[0056] Among them, an aerosol-generating article refers to an article including an aerosol-generating substrate, and the aerosol-forming substrate is intended to be heated rather than burned to release volatile compounds that can form an aerosol. When heated, the aerosol-generating substrate releases volatile compounds that can form an aerosol. Compared with the aerosol generated by burning or pyrolytic degradation of the aerosol-forming substrate, the aerosol formed by heating the aerosol-forming substrate may contain fewer known harmful components. The aerosol-generating article can be disposable or reusable. The aerosol-forming substrate can be a solid aerosol-forming substrate. Alternatively, the aerosol-forming substrate can include solid and liquid components. The aerosol-forming substrate can include tobacco and / or non-tobacco materials; or the aerosol-forming substrate can include tobacco-containing materials and / or non-tobacco materials; among them, the tobacco-containing materials contain volatile tobacco flavor compounds released from the substrate when heated.

[0057] Further, as Figures 3 to 7 shown, a first limiting portion 41 can be provided on the operating member 4, and a second limiting portion 21 corresponding to the first limiting portion 41 can be provided on the cover body 2. When the heating cavity 31 is closed, the first limiting portion 41 is connected to and abuts against the second limiting portion 21, ensuring the sealing performance after the heating cavity 31 is closed and preventing the aerosol from escaping between the main body portion 1 and the cover body 2.

[0058] In some embodiments, as Figures 5 to 7 shown, the first limiting portion 41 and the second limiting portion 21 can be one of a buckle and a clamping groove and the other respectively. By adopting the cooperation mode of the buckle and the clamping groove, the first limiting portion 41 and the second limiting portion 21 can be quickly connected or separated. Exemplarily, the first limiting portion 41 can be a buckle, and the second limiting portion 21 can be a clamping groove. When the operating member 4 is in the first state, the buckle and the clamping groove are engaged, and the cover body 2 is always in the position of closing the heating cavity 33; when the operating member 4 is in the first state, the buckle and the clamping groove are separated, and the cover body 2 switches to the position of opening the heating cavity 33. In other embodiments, the first limiting portion 41 can be a clamping groove, and the second limiting portion 21 can be a buckle.

[0059] Further, as Figure 3 and Figure 5As shown, the main body part 1 may be provided with a guiding channel 11. At least part of the operating member 4 may be located within the guiding channel 11, and the operating member 4 can slide back and forth within the guiding channel 11. A reset member 12 is arranged within the guiding channel 11. One end of the reset member 12 is sleeved on the operating member 4, and the other end abuts against the main body part 1. The reset member 12 is used to reset the first limiting portion 41. Exemplarily, when a user presses the operating member 4, the operating member 4 can slide inside the guiding channel 11 along a first direction, so that the first limiting portion 41 is separated from the second limiting portion 21, facilitating the opening of the cover body 2. At this time, the reset member 12 is deformed by force and is adapted to drive the first limiting portion 41 to reset. The reset member 12 can be a tension spring or a spring. After the cover body 2 is buckled with the main body part 1 and the user releases the operating member 4, part of the operating member 4 slides out of the guiding channel 11 along the first direction under the action of the reset member 12, and the first limiting portion 41 is connected to the second limiting portion 21, preventing the cover body 2 from separating.

[0060] Further, as Figure 3 、 Figure 5 、 Figure 6 Combined with Figure 7 As shown, the operating member 4 may further include a pressing portion 42 and an extending portion 43. The pressing portion 42 and the extending portion 43 are respectively arranged at two ends of the operating member 4, and the first limiting portion 41 is located between the pressing portion 42 and the extending portion 43. At least part of the pressing portion 42 is exposed outside the guiding channel 11. The extending portion 43 is sleeved on one end of the reset member 12. The user can push the operating member 4 to move within the guiding channel 11 by operating the pressing portion 42. The reset member 12 can be a spring, and the extending portion 43 can be sleeved on one end of the spring, enabling the operating member 4 to have an automatic reset function and reducing the operation difficulty. Further, an anti-slip structure is provided on the surface of the pressing portion 42.

[0061] In some embodiments, as Figure 4 shown, the aerosol generating device further includes a first elastic connecting member 100. One end of the first elastic connecting member 100 is connected to the main body part 1, and the other end of the first elastic connecting member 100 is connected to the cover body 2. The first elastic connecting member 100 is adapted to constantly drive the cover body 2 to move towards the open position. Exemplarily, the first elastic connecting member 100 can be a spring. A blind hole 17 is provided on the main body part 1. One end of the spring is fixed within the blind hole 17, and the other end can abut against the cover body 2 when the heating chamber 33 is closed, or can open the cover body 2 when the operating member 4 is separated from the cover body 2. In some other embodiments, a blind hole 17 can also be provided on the cover body 2. One end of the spring is fixed within the blind hole 17, and the other end can abut against the main body part 1 when the heating chamber 33 is closed.

[0062] Further, as Figure 3 and Figure 5As shown, the aerosol generating device may further include a second elastic connecting member 10. A rotating shaft 13 is provided on the main body portion 1, and the cover 2 is connected to the main body portion 1 through the rotating shaft 13. The second elastic connecting member 10 is sleeved on the rotating shaft 13. One end of the second elastic connecting member 10 is connected to the main body portion 1, and the other end of the second elastic connecting member 10 abuts against the cover 2. The second elastic connecting member 10 may be a torsion spring. The helical section of the torsion spring is sleeved on the rotating shaft 13. One end of the torsion spring is connected to the main body portion 1, and the other end of the torsion spring abuts against the cover 2. The torsion spring can make the cover 2 always have a tendency to close or open with the main body portion 1.

[0063] Usage case one: When the torsion spring makes the cover 2 always have a tendency to close with the main body portion 1, the automatic closing of the cover 2 and the main body portion 1 can be achieved by adding a torsion spring. However, when replacing consumables or cleaning the heating chamber 33, the cover 2 needs to be opened by manually overcoming the torsion force of the torsion spring. Usage case two: When the torsion spring makes the cover 2 always have a tendency to open with the main body portion 1, the automatic opening of the cover 2 and the main body portion 1 can be achieved by adding a torsion spring, avoiding time-consuming and laborious efforts.

[0064] In some embodiments, the cover 2 and the main body portion 1 can also be closed by an electromagnetic control method. For example, an element that generates magnetic force using the electromagnetic principle is provided on the cover 2, and a metal part is provided on the main body portion 1 corresponding to the element. By pressing the operating member 4 to make the element energized to generate magnetic force, the cover 2 can be attracted to and closed with the main body portion 1 under the action of the magnetic force to define the heating chamber 33.

[0065] As Figure 3 and Figure 5 As shown, a locking member 5 is further provided in the main body portion 1. The locking member 5 is configured to interfere with or separate from the operating member 4. Among them, when the locking member 5 interferes with the operating member 4, the operating member 4 is locked; when the operating member 4 and the locking member 5 are in a separated state, the operating member 4 can move. Exemplarily, when the user needs to open the cover 2, the locking member 5 is separated from the operating member 4, and the operating member 4 is pressed. In this way, by adding the locking member 5, it can be ensured that the operating member 4 is not misoperated, achieving the function of a child lock.

[0066] Furthermore, the locking member 5 can keep the operating member 4 in a first state or a second state. It can be understood that the locking member 5 can lock the operating member 4 when the cover 2 is closed, and at this time the operating member 4 is in the first state; it can also lock the operating member 4 when the cover 2 is opened, and at this time the operating member 4 is in the second state. It can also be understood that the locking member 5 can lock the operating member 4 when the heating chamber 33 is closed, and at this time the operating member 4 is in the first state; it can also lock the operating member 4 when the heating chamber 33 is opened, and at this time the operating member 4 is in the second state.

[0067] Exemplarily, after the cover 2 is opened, the locking member 5 can continue to maintain a state of being separated from the operating member 4. In this state, the operating member 4 can be first reset under the action of the reset member 12, that is, reset from the second state to the first state under the action of the reset member 12. When the cover 2 needs to be closed, it only needs to snap the cover 2 so that the first limiting portion 41 cooperates with the second limiting portion 21.

[0068] In another example, after the cover 2 is opened, the locking member 5 can maintain an interfering state with the operating member 4. In this state, the operating member 4 can be maintained in a state where the reset member 12 is compressed, that is, the operating member 4 is maintained in the second state. When the cover 2 needs to be closed, the cover 2 can be first snapped to the position where the first limiting portion 41 cooperates with the second limiting portion 21, and then the locking member 5 is separated from the operating member 4. Further, the operating member 4 is switched from the second state to the first state under the action of the reset member 12, and the second limiting portion 21 cooperates with the first limiting portion 41, avoiding wear between the second limiting portion 21 and the first limiting portion 41.

[0069] In some embodiments, as Figures 5 to 7 shown, a telescopic portion 51 can be provided on the locking member 5, and a stepped portion 44 corresponding to the position of the telescopic portion 51 is provided on the operating member 4; when the telescopic portion 51 extends, it abuts against the stepped portion 44, and when the telescopic portion 51 contracts, it separates from the stepped portion 44. The telescopic portion 51 on the locking member 5 moves upward in the second direction, so that the telescopic portion 51 abuts against the stepped portion 44. Even if the user presses, the operating member 4 will not move in the first direction, and the operating member 4 always remains in the first state. Only when the telescopic portion 51 on the locking member 5 moves downward in the second direction, so that the telescopic portion 51 separates from the stepped portion 44, and the user presses the operating member 4, the operating member 4 drives the first limiting portion 41 to separate from the second limiting portion 21 of the cover 2, and then the cover 2 is switched to the position of opening the heating chamber 33. The telescopic portion 51 can be an iron core, and the iron core is moved up and down in the second direction by controlling the on-off of the coil circuit.

[0070] Furthermore, as Figure 3 and Figure 4As shown, a first magnetic attraction member 14 is provided on the main body portion 1, and a second magnetic attraction member 22 corresponding to the position of the first magnetic attraction member 14 is provided on the cover body 2. When the heating chamber 33 is closed, the first magnetic attraction member 14 and the second magnetic attraction member 22 are attracted to each other. The second magnetic attraction member 22 can be provided at one end of the cover body 2 away from the rotation axis 13. When the second elastic connection member 10 is a torsion spring and the torsion spring is adapted to keep the cover body 2 in an open state, the magnetic attraction force between the first magnetic attraction member 14 and the second magnetic attraction member 22 is not greater than the acting force of the torsion spring on the cover body 2, so that when the user presses the pressing portion 42 of the operating member 4 to separate the first limiting portion 41 from the second limiting portion 21, the torsion spring can smoothly separate the cover body 2 from the main body portion 1. When the second elastic connection member 10 is a torsion spring and the torsion spring is adapted to keep the cover body 2 in a closed state, the magnetic attraction force between the first magnetic attraction member 14 and the second magnetic attraction member 22 should not be too large to avoid difficulty in opening the cover body 2.

[0071] Exemplarily, both the first magnetic attraction member 14 and the second magnetic attraction member 22 are magnets, and the magnetic properties of the first magnetic attraction member 14 and the second magnetic attraction member 22 are opposite; in another example, one of the first magnetic attraction member 14 and the second magnetic attraction member 22 can be a magnet, and the other can be an iron block.

[0072] In some embodiments, the heating assembly 3 includes a first accommodation groove 31 and a second accommodation groove 32. Heating sheets can be provided in both the first accommodation groove 31 and the second accommodation groove 32. The tobacco in the heating chamber 33 can be heated circumferentially through the heating sheets. Heating needles can also be provided in the first accommodation groove 31 and the second accommodation groove 32 to achieve intermediate heating by inserting the heating needles into the tobacco. Exemplarily, the first accommodation groove 31 can be formed on the main body portion 1, and the second accommodation groove 32 can be formed at a position corresponding to the first accommodation groove 31 on the cover body 2; heating sheets are provided inside both the first accommodation groove 31 and the second accommodation groove 32, and when the cover body 2 and the main body portion 1 are closed, the heating sheets inside the first accommodation groove 31 and the second accommodation groove 32 can jointly define a heating space for heating the aerosol generating article.

[0073] Further, the heating component 3 is located at the first end of the main body portion 1, the suction nozzle 6 is located at the second end of the main body portion 1, one end of the air pipe 7 is communicated with the heating cavity 33 of the heating component 3, and the other end of the air pipe 7 is communicated with the suction nozzle 6. In this embodiment, the suction nozzle 6 and the heating component 3 are respectively located at opposite ends of the main body portion 1, and the two are communicated through the air pipe 7. During the movement of the aerosol generated by the heating component 3 along the air pipe 7, the air pipe 7 can also play a role in cooling, further ensuring the user experience. The control circuit board 9 and the power supply module 8 are arranged in the main body portion 1, and the control circuit board 9 is electrically connected to the power supply module 8. The power supply module 8 includes a storage battery. A start key 16 and a charging port 15 are also arranged on the main body portion 1, and the storage battery is charged through the charging port 15. By abutting the start key 16 against the trigger 91 of the control circuit board 9, the start and stop of the heating component 3 are controlled.

[0074] In summary, the working principle of the aerosol generating device in this embodiment can be as follows: When the cover body 2 is in the second state: the locking member 5 is energized, the telescopic portion 51 moves downward along the second direction, and the user presses the operating member 4 to separate the first limiting portion 41 from the second limiting portion 21. Under the action of the second elastic connecting member 10, the cover body 2 is opened to achieve the purpose of cleaning and replacing the consumables. When the cover body 2 is in the first state: the cover body 2 is closed, and under the action of the reset member 12, the first limiting portion 41 buckles the second limiting portion 21 of the cover body 2, the locking member 5 is de-energized, and the telescopic portion 51 moves upward along the second direction and blocks the stepped portion 44 to prevent the cover body 2 from being bounced open due to accidental contact with the operating member 4.
