Description

Technical Field

[0001] This utility model relates to a lighter, specifically a fuel lighter. Background Technology

[0002] A lighter is a small fire-starting device, mainly used for starting a fire, smoking, and also for cooking and other purposes. Lighters can be classified by fuel type (liquid lighters and gas lighters) and by ignition method (flicker lighters and electronic lighters). A typical flicker lighter usually includes a shell, frame, inner liner, wick, and flicker ignition assembly. The inner liner contains a fuel reservoir, usually with cotton inside. The ignition assembly is mounted on the shell and corresponds to the wick; it typically includes a flicker and a flint. Ignition is achieved by rotating the flicker, which sparks against the flint to ignite the wick. Most existing fuels use kerosene, which is highly volatile. When not ignited, the fuel absorbed by the wick will continuously evaporate. Once the fuel is depleted, it needs to be refilled. Existing fuel lighters typically refill from the bottom, either through the bottom of the inner liner or by passing through the bottom of the outer shell to the fuel reservoir. This structure results in poor integrity of the bottom of the inner liner, making it prone to leakage. Refilling from the bottom of the inner liner requires separating the inner liner from the outer shell, which means that the inner liner cannot fit well with the outer shell during installation, affecting the product's usability. Utility Model Content

[0003] To address the problem of inconvenient refueling in existing fuel lighters, this invention provides a fuel lighter.

[0004] The technical solution of this utility model is: a fuel lighter, including a shell, and further comprising: The mechanism is located inside the housing and is detachably connected to the housing; the mechanism has a accommodating cavity for holding fuel.

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings: Depend on Figure 1 Combination Figure 2-5 As shown, a fuel lighter includes a housing 1, and further includes: The mechanism 2 is located inside the housing 1 and is detachably connected to the housing 1; the mechanism 2 is provided with a housing cavity 21 for holding fuel. The oil filling hole 22 is located on the side wall of the movement 2 and is connected to the receiving cavity 21; A positioning component 3 is located inside the oil filling hole 22. The positioning component 3 includes a screw cap 31. The screw cap 31 is located on the side wall of the movement 2 and is detachably connected to the movement 2. The screw cap 31 has a first position where the receiving cavity 21 is sealed during installation and a second position where it is open to allow oil to be added to the receiving cavity 21 through the oil filling hole 22. The advantages of this invention are that the movement is detachably connected to the housing, facilitating the removal and placement of the movement; the oil filling hole is located on the side wall of the movement, facilitating oil filling and preventing leakage. This invention also has advantages such as simple structure, convenient assembly, reliable operation, and long service life. Specifically, the middle frame of this invention is equipped with a grinding wheel ignition component and an igniter. The grinding wheel ignition component typically includes a grinding wheel and a flint. The flint ignites the igniter. One end of the igniter is inserted into the receiving cavity to absorb oil, and the other end is used for ignition. Cotton or similar materials can also be placed inside the receiving cavity. The fuel for this fuel lighter can be kerosene, gasoline, or other fuels.

[0022] The positioning component 3 includes an elastic element 32 and a limiting element 33 that cooperates with the inner wall of the housing 1 to limit the movement 2. The elastic element 32 abuts against the limiting element 33 and has a tendency to drive the limiting element 33 to protrude from the screw cap 31 for limiting movement. The limiting element and the screw cap are arranged on the same axis. When lubricating, the screw cap can be removed to directly lubricate. The limiting element inserted into the housing can provide a limit, making the movement and the housing fit conveniently and reliably, and preventing the movement from shaking or shifting within the housing.

[0023] The screw cap 31 has a groove 311, and the limiting member 33 is disposed within the groove 311 and protrudes from the groove 311 for limiting. Specifically, the positioning component 3 includes a mounting member 34, which is inserted into the groove 311, and the limiting member 33 is disposed within the mounting member 34 and is limited by the mounting member 34. More specifically, the mounting member 34 is tubular and is interference-fitted with the screw cap 31. More specifically, the limiting member can be a ball bearing. This structure makes the limiting member easy to install, has a simple structure, and forms a near-integral structure with the screw cap, facilitating disassembly and maintenance, easy lubrication, and does not occupy other space in the movement. Furthermore, the screw cap of this invention can be replaced with a flat screw cap without a ball bearing to match smaller-sized cases on the market, thus broadening the product's compatibility.

[0024] The screw cap 31 is threadedly connected to the oil filling hole 22, and the distance between the limiting member 33 and the oil filling hole 22 is adjusted by rotating relative to the movement 2. The screw cap 31 is provided with an operating groove 312 for easy operation. Specifically, it also includes a countersunk hole 23 on the movement 2, which is connected to the oil filling hole 22. The screw cap 31 includes a rotating head 313, which is located inside the countersunk hole 23 and its side wall is adapted to the inner wall of the countersunk hole 23. Specifically, the rotating head has a certain thickness and can move relative to the countersunk hole. In actual use, the tightness can be freely adjusted. If the gap between the movement and the housing changes after long-term use, tightening the screw cap outward can make the movement and the housing fit more tightly, while tightening it inward will loosen the fit, thus extending the product's service life.

[0025] This utility model also includes a middle frame 4, which is disposed on the movement 2. Specifically, the middle frame 4 is inserted into the upper surface of the movement 2 and connected by bolts. More specifically, the middle frame and the movement can adopt a similar upper and lower structure, with the middle frame inserted into the movement for connection, allowing for integral replacement of the product, easy removal during lubrication, simple structure, and convenient and reliable fixing.

[0026] The aforementioned movement 2 is integrally formed from metal material. The bottom of this movement has a coverless structure and is integrally formed, resulting in better sealing performance and preventing fuel (oil fuel) leakage and evaporation from the bottom.
