Description

Technical Field

[0001] The utility model relates to an improved structure of a lighter gas tank, in particular to an improved structure of a lighter gas tank that eliminates the need for manual rotation of the gas outlet valve. Background Art

[0002] In existing lighters, the lighter gas tank and the gas outlet valve are connected by a threaded structure. For this connection structure, the gas outlet valve needs to be rotated one by one and then connected to the lighter gas tank through the threaded structure. Each time, only one lighter gas tank can be assembled, resulting in low assembly efficiency and increased production costs of the lighter. It cannot be applied to the existing use of flip-type assembly parts to achieve batch assembly production. Flip-type assembly parts are to place two parts that need to be buckled or sleeved together on two templates respectively. The templates are provided with multiple (usually about 300) slots for placing the parts to be assembled. Then, the two templates are buckled together, and the parts on the two templates can be assembled together. The more the part slots on the template are designed, the more parts can be assembled at one time, so as to improve the assembly production efficiency and reduce the product cost.

[0016] An improved structure of a lighter gas tank with a manually rotatable air outlet valve includes a lighter gas tank 1, an air outlet valve 2, an air inlet valve 3 and an air outlet valve bracket 4. An air outlet valve installation hole is formed in the upper part of the lighter gas tank 1, and an air inlet valve installation hole is formed in the lower part. The lower part of the air outlet valve 2 is sleeved in the air outlet valve installation hole. The air outlet valve bracket 4 is clamped on the top of the lighter gas tank 1. The air outlet valve 2 is limited between the air outlet valve bracket 4 and the lighter gas tank 1. The air inlet valve 3 extends into the lighter gas tank 1 from the air inlet valve installation hole, and the upper end of the air inlet valve 3 is threadedly connected to the lower end of the air outlet valve 2. The air outlet nozzle 201 on the upper part of the air outlet valve 2 extends into the air outlet valve bracket 4.

[0017] A group of side plates 101 are oppositely arranged on the top of the lighter gas tank 1, and bracket buckling holes 102 are oppositely formed on the side plates 101. Buckling convex points 401 buckled into the bracket buckling holes 102 are arranged on the air outlet valve bracket 4.

[0018] The side plate 101 is provided with side plate screw holes 103, and the valve bracket 4 is provided with bracket screw holes 402 corresponding to the positions of the side plate screw holes 103. Screws pass through the side plate screw holes 103 and the bracket screw holes 402 to fix the valve bracket 4 and the lighter gas tank 1 together. The fixation is firm.

[0019] The top of the intake valve 3 is provided with a filter screen 5 and an air regulating sponge 6. The filter screen 5 and the air regulating sponge 6 are squeezed between the intake valve 3 and the outlet valve 2. This facilitates the adjustment of the size of the lighter flame.

[0020] The outer wall of the outlet valve 2 is provided with an outlet valve sealing groove 202. An outlet valve sealing ring 7 is sleeved on the outlet valve sealing groove 202. The outlet valve sealing ring 7 is squeezed between the outlet valve 2 and the wall of the outlet valve mounting hole. The outer wall of the intake valve 3 is provided with an intake valve sealing groove 301. An intake valve sealing ring 8 is sleeved on the intake valve sealing groove 301. The intake valve sealing ring 8 is squeezed between the intake valve 3 and the wall of the intake valve mounting hole. The outlet valve sealing ring 7 and the outlet valve 2 can also be assembled through the following flap assembly process, and only the flaps corresponding to the parts need to be made. The flaps corresponding to the parts only need to be provided with placement slots for placing the corresponding parts on the flaps. The intake valve sealing ring 8 and the intake valve 3 can also be assembled through the flap assembly process.

[0021] The outlet valve 2 is integrally formed with a limit tooth disc 203. A limit tooth hole 403 that cooperates with the limit tooth disc 203 is provided inside the valve bracket 4. The limit tooth disc 203 is meshed and connected inside the limit tooth hole 403.

[0022] The outlet nozzle 201 on the outlet valve 2 passes through the limit tooth hole 403 and extends into the outlet valve bracket 4. An inwardly extending flange 404 is provided inside the limit tooth hole 403. The lower bottom surface of the flange 404 abuts against the upper top surface of the limit tooth disc 203, restricting the upward movement of the outlet valve 2. After the outlet valve bracket 4 is installed, the rotation and upward movement of the outlet valve 2 can be restricted.

[0023] As Figure 1 、 Figure 2 and Figure 3As shown in the figure, through structural improvements, the solution of the present application has changed the threaded structure between the air outlet valve 2 and the lighter gas tank 1. When assembling the two, there is no need to relatively rotate the two components. They are connected by a direct socket structure. The air outlet valve 2 is sleeved in the air outlet valve installation hole of the lighter gas tank 1, and the valve bracket 4 is buckled on the top of the lighter gas tank 1 to limit the air outlet valve 2 between the valve bracket 4 and the lighter gas tank 1 to complete the assembly. This assembly process can be achieved through the process of assembling parts with a flap type. For example, place a number of lighter gas tanks 1 on the gas tank flap (there are a number of gas tank placement holes on the gas tank flap, usually 200), place a number of air outlet valves 2 on the air outlet valve flap (there are a number of air outlet valve placement holes on the air outlet valve flap, usually 200), and put the sides with components of the gas tank flap and the air outlet valve flap together, then the air outlet valve 2 can be assembled into the air outlet valve installation hole of the lighter gas tank 1, achieving the installation of 200 at a time, greatly improving the assembly efficiency. Through the same process, the valve bracket 4 can be buckled and installed on the lighter gas tank 1 with the air outlet valve 2. Finally, insert the intake valve 3 through the intake valve installation hole and thread it to the air outlet valve 2. Rotate the intake valve 3 to adjust the distance between the intake valve 3 and the air outlet valve 2, and then the extrusion degree of the adjustable air sponge 6 can be adjusted to achieve the adjustment of the lighter flame.
