[0021] like Figures 1 to 5 As shown in the figure, a cigarette lighter with a rotary decompression structure is provided in an embodiment of the present invention. It includes a housing and a cigarette lighter assembly disposed within the housing. The outer periphery of the housing has a mounting groove 211. A rotary decompression assembly is provided within the mounting groove 211. The rotary decompression assembly includes a fixed shaft assembly and a rotating component 3 with a central through hole 31. The fixed shaft assembly includes a fixed upper shaft 4 and a fixed lower shaft 5 arranged concentrically. The fixed upper shaft 4 includes a first shaft portion 41 and a first limiting protrusion 42 connected along its axial direction. The fixed lower shaft 5 includes a second shaft portion 51 and a second limiting protrusion 52 connected along its axial direction. The first shaft portion 41 and the second shaft portion 51 pass through the central through hole 31 from both ends and form a rotating shaft. The first limiting protrusion 42 and the second limiting protrusion 52 are located at both ends of the rotating shaft and are fixedly connected to the inner wall of the mounting groove 211 on the corresponding side. The diameters of the first limiting protrusion 42 and the second limiting protrusion 52 are both larger than the diameter of the rotating shaft. A first limiting annular groove 401 is formed between the first limiting protrusion 42, the second limiting protrusion 52 and the outer periphery of the rotating shaft. The rotating component 3 rotates around the rotating axis and its inner circumference is axially limited within the first limiting annular groove 401.

[0022] With this design, users can rotate the cigarette lighter around its axis by turning a rotating component, giving it a stress-relieving and entertaining effect in addition to its basic ignition function. Users can adjust the rotation speed of the component by adjusting the tangential force applied to it, and can continuously accelerate it by turning the component, making it highly entertaining and effective for stress relief. The separate fixed shaft assembly makes the device easy to assemble while providing excellent rotational stability.

[0023] In this embodiment, the fixed upper shaft and the fixed lower shaft are made of identical components, which further reduces production costs and improves installation convenience.

[0024] The rotary decompression assembly also includes a rotary bearing 6 disposed between the rotary shaft and the rotary component 3.

[0025] This design improves the stability of rotating parts around the axis of rotation and reduces frictional loss between them, thus enhancing the product's durability.

[0026] The rotating component 3 has a central hole along its axial direction including a first diameter hole 311 and a second diameter hole 312 connected to each other. The diameter of the first diameter hole 311 is larger than that of the second diameter hole 312 and forms a limiting step 313 with it. The outer diameter of the rotating bearing 6 is adapted to the first diameter hole 311. The rotating bearing 6 passes through the first diameter hole 311 from one end and abuts against the limiting step 313.

[0027] This feature, with its limiting step, improves the ease of installing the rotating bearing and also enhances the structural stability of the product during use.

[0028] The lower outer periphery of the first shaft portion 41 is provided with a first abutting ring groove 411, and the upper outer periphery of the second shaft portion 51 is provided with a second abutting ring groove 511. The first shaft portion 41 and the second shaft portion 51 pass through their inner holes from both ends of the rotating bearing 6 and axially limit the rotating bearing 6 between the first abutting ring groove 411 and the second abutting ring groove 511.

[0029] This design improves the ease of assembly. During installation, the rotating bearing is first inserted into the first diameter hole, and then the fixed upper shaft and fixed lower shaft are respectively inserted into the rotating component and the rotating bearing. Alternatively, the fixed upper shaft / fixed lower shaft can be connected to the rotating bearing and inserted into the rotating component first, and then the other fixed shaft can be installed.

[0030] The rotating member 3 includes, along its radial direction, a first limiting ring portion 32 located within a first limiting ring groove 401 and a second actuating ring portion 33 connected to the outer periphery of the first limiting ring portion 32. The axial length of the second actuating ring portion 33 is greater than that of the first limiting ring portion 32. A first limiting groove 34 adapted to the shape of the first limiting protrusion 42 and a second limiting groove 35 adapted to the shape of the second limiting protrusion 52 are respectively formed between the inner periphery of the second actuating ring portion 33 and the upper and lower ends of the first limiting ring portion 32.

[0031] This design improves the ease of installation and the stability of the fit between the rotating parts and the fixed upper and lower shafts.

[0032] The mounting groove 211 is provided with guide rails 212 parallel to its insertion direction at both ends relative to the fixed shaft assembly. The first limiting protrusion 42 and the second limiting protrusion 52 are each provided with guide grooves 421 that are adapted to the shape of the corresponding side guide rails 212 and form an interlocking fit.

[0033] This design improves installation convenience while providing a certain radial limit to the fixed shaft assembly via the guide rail.

[0034] One end of the guide groove 421 extends to communicate with the outer wall of the fixed shaft assembly, and the other end does not communicate with the outer wall of the fixed shaft assembly and forms an abutting end face 4211 that abuts against the guide rail 212.

[0035] This design serves as a marker to indicate the proper installation of the guide rail and guide groove on the abutting end. At least one end of the fixed shaft assembly is provided with a mounting screw hole 422 for fixing it to the housing. In this embodiment, both ends of the fixed shaft assembly are provided with mounting screw holes.

[0036] The mounting groove 211 has a recessed arc portion 2111 on its side wall that matches the circumferential shape of the rotating component 3, and part of the rotating component 3 is located within the recessed arc portion 2111.

[0037] This design improves the stability of the rotating parts and makes them less prone to dislocation.

[0038] The rotating component 3 has at least one recessed annular groove 36 along its axial direction on its outer periphery.

[0039] This setting improves the handling feel of the rotating parts.

[0040] The housing includes a main housing part 1 and a mounting bracket 2. The main housing part 1 has an upper opening and a groove 11 connected to the upper opening on one side. The mounting bracket 2 is connected to the upper opening of the main housing part 1 and has a C-shaped connecting part 21 that is adapted to the shape of the groove 11. The recess of the C-shaped connecting part 21 forms the mounting groove 211.

[0041] The mounting bracket 2 is also provided with a flame outlet 22, and the mounting bracket 2 is also hinged with a flip cover 7, which covers the outside of the mounting bracket 2.

[0042] This device can be equipped with cigarette lighter components of various principles. In this embodiment, a voice-controlled arc cigarette lighter component is specifically used.

[0043] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
