[0035] As Figures 1 - 12b shown, a mechanical self-starting heated cigarette appliance provided by an embodiment of the present application will now be described.

[0036] Provided is a mechanical self-starting heated cigarette appliance, including a housing, a bracket, a guide rail, a battery 19, a circuit board 11 and a heating element 8. The housing includes an upper housing 14 and a lower housing 10, and the upper housing 14 and the lower housing 10 are snap-connected. The bracket includes an upper bracket 13 and a lower bracket 9, and the upper bracket 13 and the lower bracket 9 are snap-connected and fastened by a first screw 22. The guide rail includes an upper guide rail 15 and a lower guide rail 16, and the upper guide rail 15 and the lower guide rail 16 are spliced and fastened by a second screw 21. The guide rail is arranged at the front end of the bracket (the insertion end of the cigarette stick 18), and the guide rail and the bracket are installed in the housing. The front end of the housing (the lower housing 10) is provided with an insertion port, and a dust-proof cover 20 is slidably arranged at the front end of the housing. The slider inside the dust-proof cover 20 is slidably assembled with the chute on the guide rail to perform sliding limit on the installation of the dust-proof cover 20. Among them, the battery 19, the circuit board 11 and the heating element 8 are all installed in the installation cavity of the bracket. The bottom of the heating element 8 is fixed in the bracket through a lower mounting bracket 17, and the top of the heating element 8 is fixed through an upper mounting bracket 7. Part of the upper mounting bracket 7 is installed in the upper part of the bracket, and the other part is installed in the guide rail. The upper mounting bracket 7 has a cigarette stick insertion channel communicating with the heating channel of the heating element 8, and the cigarette stick insertion channel is aligned with the insertion port. The circuit board 11 is electrically connected to the battery 19 and the heating element 8, and a charging interface 12 is provided at the bottom of the housing for charging the battery 19.

[0037] Specifically, as Figure 1 , Figure 3 and Figure 4 shown, an assembly hole 702 is provided on the side wall of the upper mounting bracket 7. The assembly hole 702 communicates with the cigarette stick insertion channel on the upper mounting bracket 7. A trigger key 1 is installed in the assembly hole 702, and the trigger key 1 protrudes into the cigarette stick insertion channel. The part protruding into the cigarette stick insertion channel has an arc surface and the upper end surface is chamfered. The function of the chamfer is to facilitate the insertion of the cigarette stick 18 and squeeze the trigger key 1. A travel detection switch 5 electrically connected to the circuit board 11 is installed in the bracket. The opening and closing of the travel detection switch 5 are used to control the opening and closing of the heating element 8. The trigger key 1 contacts the elastic trigger point 501 of the travel detection switch 5, and a return spring 2 is arranged between the trigger key 1 and the travel detection switch 5. When the cigarette stick 18 is inserted through the insertion port on the housing, when passing through the cigarette stick insertion channel, the side wall of the cigarette stick 18 squeezes the trigger key 1, so that the trigger key 1 moves in the direction of withdrawing from the upper mounting bracket 7, so that the trigger key 1 touches the elastic trigger point 501 of the travel detection switch 5, so that the travel detection switch 5 is turned on, and the heating element 8 automatically heats up. At this time, the return spring 2 is in a compressed state; when the cigarette stick 18 is pulled out, the cigarette stick 18 cancels the squeezing force on the trigger key 1, the return spring 2 automatically returns, driving the trigger key 1 to cancel the squeezing force on the elastic trigger point 501, the elastic trigger point 501 resets, the travel detection switch 5 closes, and the heating element 8 automatically stops heating.

[0038] As Figure 6As shown in the figure, in this embodiment, several clamping walls 701 protrude from the inner wall of the cigarette insertion channel of the upper mounting bracket 7. The upper ends of the clamping walls 701 are chamfered to facilitate the insertion of the cigarette 18. The clamping walls 701 are used to cooperate with the trigger key 1 and the return spring 2 to clamp the cigarette 18 and prevent the cigarette 18 from loosening and automatically withdrawing from the heating element 8.

[0039] As Figure 1 , Figure 5 , Figure 6 , Figure 7a , Figure 7b , Figure 9a , Figure 9b and Figure 10 As shown in the figure, in this embodiment, in order to prevent the water vapor generated during the heating process of the cigarette 18 from affecting other components in the bracket, such as the circuit board, an airway waterproof silicone part 3 for sealing the upper end surface and the outer end surface of the assembly hole 702 is sleeved on the upper mounting bracket 7. Specifically, the upper mounting bracket 7 includes a circular tube part and a rectangular frame part. One end of the circular tube part is used to dock with the tubular heating element 8, and the other end is docked with the insertion port on the lower shell 10. The rectangular frame part is arranged on the side of the circular tube part, and the rectangular frame part and the circular tube part are internally connected to form an assembly hole 702; the airway waterproof silicone part 3 includes an inner rectangular sealing surface 303, an outer rectangular sealing surface 301, an inner circular sealing surface 304, and an outer circular sealing surface 302. Among them, the inner rectangular sealing surface 303 is sealingly attached to the rectangular frame outer end sealing surface 703 of the rectangular frame part, the inner circular sealing surface 304 is sealingly attached to the circular tube upper end sealing surface 704 of the circular tube part, the outer rectangular sealing surface 301 is sealingly attached to the inner sealing surface 1302 of the mounting part of the upper bracket 13, and the outer circular sealing surface 302 is sealingly attached to the inner circular sealing surface 1001 on the lower shell 10.

[0040] To ensure the sealed assembly between the trigger key 1 and the travel detection switch 5, the travel detection switch 5 is connected with a detection switch silicone key 4. The inner side of the detection switch silicone key 4 contacts the elastic trigger point 501, and the outer side of the detection switch silicone part contacts the trigger key 1. The function of the detection switch silicone key 4 is to seal the channel between the upper bracket 13 and the assembly hole 702. The airway waterproof silicone part 3 is used to seal the assembly gap between the upper bracket 13 and the upper mounting bracket 7, so that the water vapor generated when the cigarette 18 is heated will not overflow from the assembly hole 702 into the bracket to damage other components. Specifically, the upper bracket 13 is provided with a mounting part, and the outer side of the mounting part is provided with an assembly groove 1303 for sealing and mounting the detection switch silicone key 4. A perforation 1304 is provided at the center of the assembly groove 1303. A trigger post 405 is connected to the detection switch silicone key 4 through an inclined elastic wall 401. The detection switch silicone key 4 is installed in the assembly groove 1303 and the trigger post 405 passes through the perforation 1304 and then contacts the trigger key 1. Specifically, the detection switch silicone key 4 is provided with a silicone key upper sealing surface 402 and a silicone key lower sealing surface 403. The assembly groove 1303 is provided with an outer groove sealing surface 1301, and the inner side of the mounting part is provided with an inner mounting part sealing surface 1302 for sealing and fitting with the outer rectangular sealing surface 301. The outer groove sealing surface 1301 is used for sealing and fitting with the silicone key upper sealing surface 402; the silicone key lower sealing surface 403 is used for sealing and fitting with the first sealing surface 601 on the FPC 6 below. The detection switch silicone key 4 can keep the travel detection switch 5 in a sealed state. In Figure 5 of the drawings, the two reference numerals in parentheses indicate the sealing and fitting of two corresponding sealing surfaces.

[0041] Specifically, as Figure 4 , Figure 5 and Figure 7a shown, a columnar trigger point 101 is provided on the inner side of the trigger key 1. One end of the return spring 2 is sleeved on the columnar trigger point 101, and the other end abuts against the inner side of the mounting part. The trigger post 405 contacts the columnar trigger point 101 inside the return spring 2. When the trigger key 1 moves backward under the extrusion of the cigarette 18, the columnar trigger point 101 drives the trigger post 405 to move inward, and drives the inclined elastic wall 401 to deform and the return spring 2 to compress, so that the trigger post 405 presses the elastic trigger point 501 of the travel detection switch 5 to be energized.

[0042] As Figure 5 , Figure 11 , Figure 12a and Figure 12bAs shown in the figure, in this embodiment, since the circuit board 11 is far from the travel detection switch 5, the travel detection switch 5 is electrically connected to the circuit board 11 through an FPC 6 (flexible printed circuit board). An installation groove 1305 for installing the FPC 6 is provided on the upper bracket 13. Both sides of one end of the FPC 6 for installing the travel detection switch 5 are hermetically assembled with the upper guide rail 15 and the detection switch silicone key 4 respectively. Specifically, one end of the FPC 6 has a detection switch installation position 603. The side where the detection switch installation position 603 is located is the first sealing surface 601, and the back surface is the second sealing surface 602. The first sealing surface 601 is used for hermetically fitting with the lower sealing surface 403 of the silicone key, and the second sealing surface 602 is used for hermetically fitting with the guide rail sealing surface 1501 on the upper guide rail 15. The purpose of this is to ensure that water vapor will not overflow to other positions of the bracket through the FPC 6.

[0043] Specifically, in this embodiment, there is a gap of 0.1 - 0.15 mm between the side wall of the trigger key 1 and the hole wall of the assembly hole 702, which is convenient for the trigger key 1 to retract when the cigarette rod 18 is inserted. In this embodiment, the alignment pre-pressure sealing is performed between each sealing surface. The battery 19, the heating element 8, and the circuit board 11 are mainly fixed in the lower bracket 9, and the upper bracket 13 is snap-fitted and then limited and fixed. The lower bracket 9 is installed in the lower shell 10. Due to the existence of the upper bracket 13 and the lower bracket 9, the wall thickness of the shell can be set to be relatively thin.

[0044] A mechanical automatic start heating cigarette appliance provided in this embodiment realizes the simultaneous completion of two steps of inserting a cigarette and turning on the machine. When the cigarette rod is inserted into the upper installation bracket 7, the appliance starts to preheat synchronously, which is simpler and faster to use and has a better user experience. If the cigarette rod is pulled out halfway, the heating element 8 can automatically stop heating, realizing intelligent operation and improving the user experience. In addition, compared with the existing appliances, since there is no power-on button, there is no accidental touch when the user carries it, and it is safer to use.

[0045] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
