The heating device 30 of the technical solution of the present invention is provided with a mounting chamber 11 and a locking device 50 in the main body 10, the user mounts the heating device 30 in the mounting chamber 11 along the opening 111 during mounting, when being mounted to the first position of the mounting chamber 11, the locking device 50 cooperates with the locking portion 321 provided by the heating device 30 to lock the heating device 30 to electrically connect the heating device 30 to the main body 10; when the detachment is required, the user controls the locking device 50 so that the locking device 50 is detached from the locking portion 321, the heating device 50 moves from the first position to the second position so that the heating device 50 partially protrudes from the opening 111 to the outside, and the user can directly pull out the heating device 30, effectively facilitating the user to detach the heating device 30 from the main body 10 of the electronic cigarette 100. At the same time, the detached heating device 30 is exposed to the outside to facilitate the user to clean.

Specifically, as shown in FIG. 1, FIG. 2 or FIG. 4, in the embodiment of the present invention, the locking device 50 comprises a locking head 51 and a controlling member 52, one end of the controlling member 52 is movably mounted to the main body 10 and exposed to the outside of the main body 10, and the other end extends into the main body 10 to be connected with the locking head 51; the controlling member 52 moves to the locking head 51 to engage with the locking portion 321, a locking state is formed so that the heating device 30 is locked in the first position, and when the controlling member 52 moves to disengage the locking head 51 from the locking portion 321, a disengaged state is formed. The heating device 30 moves from the first position to the second position. Here, in the present embodiment, one end of the controlling member 52 is exposed to the outside of the main body 10, and the other end extends into the main body 10 to be connected with the locking head 51; when the user drives the controlling member 52 to move, the locking head 51 is driven to move, effectively facilitating the user to control.

Specifically, the main body 10 is provided with a connecting hole, one end of the controlling member 52 is exposed outside the connecting hole, and the other end is received in the main body 10 to be connected with the locking head 51 through the connecting hole. The user presses the controlling member 52 so that the controlling member 52 moves toward the main body 10 along the connecting hole, thereby driving the locking head 51 to engage with the mounting portion so as to lock the heating device 30 in the first position of the mounting chamber 11.

It can be understood that, in the actual application process, the controlling member 52 and the main body 10 are not limited to the above splicing manner using the connecting hole; for example, in another embodiment of the present invention, the main body 10 can also be provided with a sliding slot. One end of the controlling member 52 is slidably mounted to the sliding slot, and the other end is received in the main body 10 through the sliding slot and is connected to the locking head 51. The manner, in which the controlling member 52 slides to drive the locking head 51, is also within the scope of protection of the present invention.

Further, as shown in FIG. 1 or FIG. 2, in the embodiment of the present invention, the locking device 50 further comprises an elastic body 53, and the elastic body 53 is mounted between the main body 10 and the controlling member 52 so that the controlling member 52 rebounds from the disengaged position to the locked position. Here, the elastic body 53 can be prepared using a material such as a spring, an elastic silicone or an elastic plastic. In the present embodiment, the elastic body 53 is a spring, one end of the spring is elastically abutted with the main body 10, and the other end is elastically abutted with the controlling member 52, so that the controlling member 52 can be rebounded from the position of the disengaged state to the position of the locked state, further facilitating the user to control and detach the heating device 30 from the mounting chamber 11.

It can be understood that, in the actual application process, the elastic body 53 is not limited to the above mounting manner of being provided between the main body 10 and the controlling member 52. For example, in another embodiment of the present invention, the mounting manner, in which the elastic body 53 may also be provided between the main body 10 and the locking head 51, and when the external force of the controlling member 52 disappears, the elastic body 53 pushes the locking head 51 to drive the controlling member 52 to move from the position of the disengaged state to the position of the locked state, is within the scope of protection of the present invention.

Specifically, as shown in FIG. 4 or FIG. 5, in the embodiment of the present invention, the locking head 51 comprises a limiting portion 511 and a connecting portion 512 connected to the limiting portion 511, the heating device 30 is provided with a locking groove to form the locking portion 321, one end of the connecting portion 512 away from the limiting portion 511 is mounted to the controlling member 52, and when the controlling member 52 moves to splice the limiting portion 511 into the locking groove, the heating device 30 is locked in the first position. Here, in the present embodiment, the heating device 30 is shaped like a cylindrical-shape of a cylinder. The locking groove is an annular locking groove extending in a circumferential direction of the heating device 30 so that when the heating device 30 is mounted to the mounting chamber 11 along the opening 111, the limiting portion 511 is always insertable into the locking groove, effectively preventing the phenomenon that the locking groove is provided in the single direction of the heating device 30, and it is necessary to mount in a certain direction during mounting, which causes inconvenience in mounting. The connecting portion 512 is provided with a through hole through which the heating device 30 passes, which has an annular shape in whole. The limiting portion 511 is convexly formed from the inner hole wall of the through hole, and the limiting portion 511 is provided away from the controlling member 52. The elastic body 53 is provided on a side of the connecting portion 512 away from the limiting portion 511. When the heating device 30 is mounted in the first position, the elastic body 53 presses the limiting portion 511 against the locking groove under the elastic force, effectively preventing the phenomenon that the heating device 30 waggles in the circumferential direction of the mounting chamber 11 during use. At the same time, the connecting portion 512 has an annular shape, which effectively disperses the locking force, and prevents the phenomenon that it is easy to deform when the single connecting plate or the connecting rod is subjected to a large force. The controlling member 52 is spliced into the main body 10 and is slidable along the main body 10. When the user presses the controlling member 52, the limiting portion 511 is driven to be disengaged from the locking groove and extrude the elastic body 53 at the same time so that the heating device 30 is detachable from the mounting chamber 11. When the external force applied by the user to the controlling member 52 is eliminated, the elastic body 53 is restored to deform, and the controlling member 52 is pushed back to the unpressed state, effectively facilitating the user to control.

It can be understood that, in the actual application process, the connecting portion 512 is not limited to the above annular form. For example, the manner, in which it is also possible to provide a shape such as a rod shape, a bent shape, a lever device or the like according to the internal space of the main body 10, is within the scope of protection of the present invention.

Similarly, the locking portion 321 is not limited to forming the locking portion 321 in such a manner that the heating device 30 is provided with a locking groove. For example, in another embodiment of the present invention, the heating device 30 may be provided with a locking hole to form a locking portion 321, the limiting portion 511 is a connecting pin, the locking hole is inserted by being driven by the controlling member 52, and the heating device 30 is locked; for another example, the heating device 30 is convexly provided with a wedge-shaped limiting block to form a locking portion 321, the limiting portion 511 is fitted to the wedge-shaped face of the limiting block, and the elastic body 53 is provided between the main body 10 and the controlling member 52. When the heating device 30 is mounted to the mounting chamber 11, the limiting block extrudes the limiting portion 511 to drive the controlling member 52 to move outwardly of the main body 10, and extrudes the elastic member 72. When the heating device 30 moves to a deeper position of the mounting chamber 11, when the limiting block is disengaged from the limiting portion 511, the limiting portion 511 moves into the mounting chamber 11 under the elastic restoring force of the elastic body 53, and is abutted against the side of the limiting block toward the opening 111 so that the heating device 30 is locked in the main body 10. The above manners are within the scope of protection of the present invention.

Specifically, as shown in FIG. 4, in the embodiment of the present invention, the connecting portion is further provided with a positioning post 513 corresponding to the elastic body 53, and the main body 10 is provided in the positioning groove corresponding to the elastic body 53, effectively preventing the phenomenon that the elastic body 53 is detached during use. At the same time, the positioning post 513 and the limiting portion 511 are provided on opposite side walls of the connecting member, so that the connecting member provided at the limiting portion 511 has a large thick size, and the stability of the limiting portion 511 is effectively enhanced.

Specifically, as shown in FIG. 1 and FIG. 2, in the embodiment of the present invention, the locking device 50 further comprises an ejecting mechanism 70, the ejecting mechanism 70 is mounted to the main body 10, when the heating device 30 is locked in the first position, the ejecting mechanism 70 is extruded, and when the locking device 50 is disengaged from the locking portion 321, the ejecting mechanism 70 pushes the heating device 30 to move from the first position to the second position. Here, in the present embodiment, an ejecting mechanism 70 is provided, the ejecting mechanism 70 is mounted to an end of the mounting chamber 11 away from the opening 111, so that when the user drives the controlling member 52 to disengage the locking head 51 from the locking portion 321, the ejecting mechanism 70 ejects the heating device 30 from the first position to the second position to expose the heating device from the opening 111, further facilitating the user to detach. At the same time, an ejecting mechanism 70 is provided. When the heating device 30 is locked in the first position, the ejecting mechanism 70 has an elastic force on the heating device 30, so that the heating device 30 is abutted against the locking head 51, effectively preventing the phenomenon that the heating device 30 waggles in the axial direction of the mounting chamber 11 during use.

Specifically, as shown in FIG. 6, in the embodiment of the present invention, the ejecting mechanism 70 comprises a supporting base 71 and an elastic member 72, the supporting base 71 is slidably mounted to the main body 10 and at least partially received in the mounting chamber 11, one end of the elastic member 72 is abutted against the supporting base 71, and the other end is abutted against the main body 10; the heating device 30 is abutted against the supporting base 71 when moving to the second position along the opening 111, when the heating device 30 moves from the second position to the first position of the mounting chamber 11, the supporting base 71 is pushed to extrude the elastic member 72 so that the locking device 50 engages with the locking portion 321; and when the locking device 50 is disengaged from the locking portion 321, the elastic member 72 pushes the supporting base 71 to move so that the heating device 30 moves from the first position to the second position. Here, the elastic member 72 may be a spring, an elastic silicone, an elastic plastic or the like. In the present embodiment, the elastic member 72 is a spring, the supporting base 71 is slidably mounted in the mounting chamber 11, and the outer peripheral surface of the supporting base 71 is fitted to the inner peripheral surface of the mounting chamber 11. One end of the elastic member 72 is elastically abutted against the chamber wall of the mounting chamber 11 away from the opening 111, and the other end is elastically abutted against the supporting base 71. The heating device 30 is elastically abutted against an end of the supporting base 71 away from the elastic member 72 when being mounted to the heating base 31 along the opening 111, so that the supporting base 71 can push the heating device 30 to move to the second position along the mounting chamber 11 under the elastic restoring force of the elastic member 72. At the same time, a supporting base 71 is provided to cover the elastic member 72, so that the aesthetic appearance performance is high. At the same time, the outer peripheral surface of the supporting base 71 is fitted to the inner peripheral surface of the mounting chamber 11, effectively preventing the phenomenon that the supporting base 71 waggles during the movement.

It can be understood that, in the actual application process, the supporting base 71 is not limited to the above mounting manner in which the outer peripheral surface is fitted to the inner peripheral surface of the mounting chamber 11 to prevent waggle; for example, the mounting manner, in which a guiding groove is also provided in the inner chamber wall of the mounting chamber 11, the outer surface of the supporting base 71 is provided with a guiding member, and the guiding member is spliced in the guiding groove to cooperatively slide to prevent waggle, is within the scope of protection of the present invention.

In addition, in the actual application process, the supporting base 71 is not limited to the above mounting manner of being received in the mounting chamber 11. For example, in another embodiment of the present invention, the manner, in which the supporting base 71 is slidably mounted in the main body 10, the inner chamber wall of the mounting chamber 11 is provided with a sliding slot, and the supporting base 71 partially extends into the mounting chamber 11 through the sliding slot and is elastically abutted against the heating device 30, is also within the scope of protection of the present invention.

At the same time, the conductive terminal 12 uses a conductive ejector pin to form an elastic contact between the conductive terminal 12 and the conductive contact 34, so that the conductive contact 34 provided in the heating device 30 is effectively closely abutted against the ejector pin provided in the mounting chamber 11 and the stability of current conduction is enhanced. Moreover, the guiding tube is slidably sleeved on the outer circumference of the conductive terminal, thereby effectively achieving positioning and preventing the phenomenon of waggling during the sliding process.
