Furthermore, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

Please refer to Figures 1-4, and the aerosol generating device provided in the embodiment of the present invention will now be described. The aerosol generating device provided by the embodiment of the present invention includes a shell component 10, a battery component 30, a cover component 40 and a locking structure 50. The battery component 30 is used to provide electrical energy. A receiving chamber 13 is provided in the shell component 10 corresponding to the battery component 30. One end of the shell component 10 is provided with an open end connected to the receiving chamber 13. The battery component 30 can be loaded into or removed from the receiving chamber 13 through the open end of the shell component 10. The cover component 40 can be detachably installed on the open end of the shell component 10 to open or close the receiving chamber 13 through the cover component 40. The locking structure 50 is arranged on the shell component 10 and/or the cover component 40, wherein when the cover component 40 is rotated to the locked position, the locking structure 50 locks the cover component 40 on the shell component 10, and when the cover component 40 is rotated to the unlocked position, the locking structure 50 releases the lock between the cover component 40 and the shell component 10, so that the battery component 30 can be moved out of the receiving chamber 13 from the open end of the shell component 10. Therefore, through the above technical scheme, the aerosol generating device provided in the embodiment of the present invention can open the open end on the outer shell component 10 by removing the cover component 40, so as to remove the battery component 30 from the accommodating cavity 13, thereby realizing the disassembly and separation of the battery component 30 and the outer shell component 1, so as to recycle the battery component 30, especially to facilitate the recycling of the battery cells 32 in the battery component 30, which is beneficial to protecting the environment; in addition, the aerosol generating device provided in the embodiment of the present invention can realize the unlocking and locking of the cover component 40 and the outer shell component 10 by rotating the cover component 40 relative to the outer shell component 10, and the operation is simple and convenient.

As shown in FIG. 4 , in some embodiments, the locking structure 50 includes a locking groove 51 recessed on the inner wall of the housing assembly 10 near the opening end, and a locking protrusion protruding on the outer wall of the cover assembly 40. 52, the locking groove 51 includes an axial channel 511 extending along the axial direction of the shell component 10, and a circumferential channel 512 extending along the circumferential direction of the shell component 10, the axial channel 511 penetrates to the outer end surface of the open end of the shell component 10, so that when the cover component 40 is moved axially, the locking protrusion 52 slides into the axial channel 511 of the locking groove 51, and then the cover component 40 is rotated circumferentially to make the locking protrusion 52 deviate from the axial channel 511 and enter the circumferential channel 512, so that the locking protrusion 52 cannot slide out along the axial channel 511 relative to the locking groove 51, and also In this way, the cover assembly 40 cannot be moved and disengaged from the housing assembly 10 in the axial direction; in addition, in order to prevent the locking protrusion 52 from rotating and disengaging when entering the circumferential channel 512, a stopper 513 is provided on the side wall of the circumferential channel 512 extending circumferentially in the locking groove 51. When the locking protrusion 52 is in place with the circumferential channel 512, the stopper 513 blocks the rotation of the locking protrusion 52. By applying appropriate force to rotate the locking protrusion 52, the locking protrusion 52 squeezes the stopper 513 to cause elastic deformation so that the locking protrusion 52 passes over the stopper 513 and enters the axial channel 511, thereby unlocking the locking structure 50. Thus, through the above technical solution, when the cover assembly 40 rotates relative to the housing assembly 10, the cover assembly 40 is installed on the open end of the housing assembly 10 or separated from the housing assembly 10 through the locking structure 50, so that the cover assembly 40 opens or closes the receiving cavity 13, and the battery assembly 30 is installed or disassembled. It is understandable that in some other embodiments not shown in the figures, the positions of the locking groove 51 and the locking protrusion 52 in the locking structure 50 can be swapped, that is, the locking groove 51 is located on the cover assembly 40, and the locking protrusion 52 is located on the housing assembly 10.

As shown in FIG5 , in some embodiments, a first guide portion 341 is disposed on the outer side of the battery assembly 30, and a second guide portion 14 matching the first guide portion 341 is disposed on the inner side of the open end of the housing assembly 10, and the first guide portion 341 can slide in the second guide portion 14 along the axial direction of the receiving cavity 13. Therefore, through the above technical solution, after the first guide portion 341 and the second guide portion 14 are aligned, the first guide portion 341 and the second guide portion 14 slide relative to each other along the axial direction of the receiving cavity 13, so that the battery assembly 30 can be loaded into the receiving cavity 13 or removed from the receiving cavity 13 along the axial direction of the receiving cavity 13, thereby preventing the battery assembly 30 from deflecting in the receiving cavity 13. Since the battery assembly 30 needs to be aligned and electrically connected with other components after being loaded into the housing assembly 10, Preventing the battery assembly 30 from deflecting in the receiving cavity 13 is conducive to completing the above-mentioned alignment and electrical connection. More specifically, the first guide portion 341 is a protruding structure, and the second guide portion 14 is a corresponding groove structure; or the first guide portion 341 is a groove structure, and the second guide portion 14 is a protruding structure.

As shown in Figures 6 and 7, in some embodiments, the battery assembly 30 includes a first traction portion 35 arranged near the open end on the outer shell assembly 10, and the cover assembly 40 is provided with a second traction portion 43 that cooperates and engages with the first traction portion 35, and when the first traction portion 35 and the second traction portion 43 cooperate and engage, the second traction portion 43 can rotate relative to the first traction portion 35, and at the same time, the second traction portion 43 can drive the first traction portion 35 to slide axially along the accommodating cavity 13. Since the second traction part 43 can drive the first traction part 35 to slide along the axial direction of the receiving cavity, when the first traction part 35 and the second traction part 43 are engaged, the mobile cover assembly 40 can drive the battery assembly 30 to be loaded into or removed from the receiving cavity 13, so that the installation and removal of the cover assembly 40 can simultaneously complete the installation and removal of the battery assembly 30, simplifying the operation and increasing the efficiency. When disassembling and recycling the battery assembly 30, it is not necessary to first remove the cover assembly 40 and then pour out the battery assembly 30, so as to avoid the battery assembly 30 being difficult to pour out of the receiving cavity 13 when the battery assembly 30 and the shell assembly 10 are tightly engaged, and there is no need to use additional tools to take out the battery assembly 30; since the second traction part 43 can rotate relative to the first traction part 35, the cooperation between the second traction part 43 and the first traction part 35 will not hinder the rotation of the cover assembly 40. More specifically, in this embodiment, the first traction part 35 has a convex structure, and the second traction part 43 has a slot structure that cooperates with the convex structure. It is understandable that in other embodiments not shown in the figures, the first traction portion 35 may have a slot structure, and the second traction portion 43 may have a corresponding convex structure.

As shown in Figure 2, in some embodiments, the shell assembly 10 includes a shell 11 with an opening at least at one end, and a connecting ring 12 connected to the inner wall of the opening at one end of the shell 11 corresponding to the cover assembly 40, the second guide portion 14 and the locking groove 51 in the locking structure 50 are located on the connecting ring 12, the atomizer 20 is installed from the opening at one end of the shell 11 away from the cover assembly 40, and the housing 30 is defined in the shell 11 and outside the atomizer 20 and the cover assembly 40.

Referring to Figures 2, 8, 10, and 11, in some embodiments, the aerosol generating device also includes an atomizer 20, a switch assembly 60, and a locking structure 70, the battery assembly 30 includes a battery cell 32 and a controller 33, the cap assembly 40 includes a fixing seat 41 and a switch member 42, the atomizer 20 is used to atomize the aerosol-forming matrix to form an aerosol, the battery cell 32 is used to power the heating element 22 and the controller 33 in the atomizer 20, the controller 33 is used to turn on or off the circuit between the battery cell 32 and the heating element 22 in the atomizer 20, or the controller 33 disconnects the circuit between the battery cell 32 and the heating element 22 when it is turned off, the switch assembly 60 is arranged on the circuit between the battery cell 32 and the controller 33, and the switch member 42 is movably arranged on the fixing seat. On the seat 41, the locking structure 70 is arranged on the switch member 42 and/or the fixed seat 41, wherein, when the switch member 42 moves to the first position 721, the switch member 42 drives the switch assembly 60 to disconnect the circuit, the circuit between the battery cell 32 and the controller 33 is turned off, the controller 33 cannot work normally, the circuit between the battery cell 32 and the heating element 22 is disconnected, and then the battery assembly 30 cannot supply power to the atomizer 20, and the locking structure 70 locks the switch member 42 on the fixed seat 41; when the switch member 42 moves to the second position 722, the switch member 42 drives the switch assembly 60 to conduct the circuit, the circuit between the battery cell 32 and the controller 33 is conducted, the controller 33 enters the working state, and the battery assembly 30 can normally supply power to the atomizer 20 when the controller 33 is activated. Therefore, by setting a switch component 60 on the circuit between the battery cell 32 and the controller 33, only when the switch component 60 conducts the circuit between the battery cell 32 and the controller 33, the controller 33 can enter the working state to control the operation of the heating element 22, thereby preventing the controller 33 from being triggered by mistake, and improving the safety of the aerosol generating device; in addition, by setting a locking structure 70 between the switch element 42 of the driving switch component 60 and the fixed seat 41, since the locking structure 70 can lock the switch element 42 in the first position 721 that turns off the switch component 60, the switch component 60 is prevented from being triggered by mistake, thereby further reducing the possibility of the controller 33 being triggered by mistake, and further improving the safety of the aerosol generating device.

In addition, in some embodiments, when the switch member 42 rotates from the second position 722 in a direction away from the first position 721, the switch member 42 drives the fixing seat 41 to rotate from the unlocking position to the locking position. and when the switch member 42 rotates from the first position 721 in the direction away from the second position 722, the switch member 42 drives the fixing seat 41 to rotate from the locked position to the unlocked position. This improves the functionality of the switch member 42. The switch member 42 can not only be used to control the switch assembly 60 to turn on and off the circuit, but also control the fixing seat 41 in the cover assembly 40 to lock on the housing assembly 10, or release the lock between the fixing seat 41 and the housing assembly 10, so as to remove the battery assembly 30.

In some embodiments, the switch assembly 60 includes a first contact 61, a second contact 62 and a conductive member 63, the first contact 61 and the second contact 62 are arranged at intervals, when the switch member 42 rotates to the first position 721, the switch member 42 drives the conductive member 63 to move and separate the first contact 61 and the second contact 62, when the switch member 42 rotates to the second position 722, the switch member 42 drives the conductive member 63 to conduct the first contact 61 and the second contact 62. In this embodiment, the first contact 61 is connected to the first electrode on the battery cell 32, the controller 33 has a first terminal, and the second contact 62 is connected to the first terminal of the controller 33. Since the switch assembly 60 composed of the contact and the conductive member 63 has a simple structure, low manufacturing cost, and the switch assembly 60 has a high reliability in completing the on-off operation.

As shown in FIG. 11 , in some embodiments, the locking structure 70 includes a locking portion 71 disposed on the outer peripheral wall of the switch member 42, a rotation groove 72 disposed on the inner peripheral wall of the fixing seat 41 and suitable for the locking portion 71 to rotate, and a locking body 73 disposed in the middle of the rotation groove 72. The rotation groove 72 is located on one side of the locking body 73 to form a first position 721, and the rotation groove 72 is located on the other side of the locking body 73 to form a second position 722. The switch member 42 is rotatably mounted on the fixing seat 41, and when the switch member 42 rotates to the first position 721, the locking portion 71 is locked by the locking body 73. Since the locking portion 71, the rotation groove 72, and the locking body 73 are all simple concave or convex structures, it is helpful to reduce the difficulty of molding and manufacturing the switch member 42 and the fixing seat 41, and the manufacturing cost is low and the reliability is high.

More specifically, the height of the locking body 73 gradually decreases from the first position 721 to the second position 722, and the end of the locking body 73 close to the second position 722 is flush with the bottom wall of the rotating groove 72. Therefore, when the switch member 42 rotates from the second position 722 to the first position 721, it is not hindered by the locking body 73 and can rotate directly. The switch member 42 simplifies the operation of the user.

It can be understood that in other embodiments not shown in the figures, the locking structure 70 includes a locking portion 71 arranged on the outer wall of the switch member 42, a rotation groove 72 arranged on the inner wall of the fixed seat 41 and suitable for the locking portion 71 to slide linearly, and a locking body 73 arranged in the middle of the rotation groove 72, and the switch member 42 is arranged on the fixed seat 41 along a linear sliding manner.

When the rotating switch member 42 drives the locking portion 71 to rotate from the first position 721 to the second position 722 in the opposite direction, the locking portion 71 is blocked by the side wall of the rotation groove 72 and cannot move relative to the fixed seat 41. Therefore, the switch member 42 will drive the fixed seat 41 to rotate to the unlocking position together, so that the locking protrusion 52 and the locking groove 51 are unlocked, and the cover assembly 40 is separated from the shell assembly 10; when the rotating switch member 42 drives the locking portion 71 to rotate from the first position 721 to the second position 722 to the second position 722, the locking portion 71 is also blocked by the rotation groove 72 and cannot move relative to the fixed seat 41.

In this way, the elastic force exerted by the conductive member 63 on the switch member 42 is used to provide an elastic force that makes the locking portion 71 on the switch member 42 always located in the rotation groove 72 of the fixing seat 41, and the main function is to prevent the switch member 42 from directly rotating to make the locking portion 71 disengage from the first position 721 that disconnects the circuit to reach the second position 722 that conducts the circuit, and the switch member 42 needs to be pushed axially before rotating the switch member 42 to resist the elastic force of the conductive member 63 to make the locking portion 71 disengage from the blocking of the locking body 73, and then the switch member 42 can be rotated to drive the switch assembly 60 to conduct the circuit, and there is no need to set elastic members other than the conductive member 63 to simplify the structure.
