Description

Technical Field

[0001] This utility model relates to the field of lighter technology, specifically a kerosene lighter. Background Technology

[0002] A lighter is a small fire-starting device; it is mainly used for starting a fire, smoking, and also for cooking and other fire-starting purposes. The main components of a lighter are the ignition mechanism and the gas tank. When the ignition mechanism is activated, it emits a spark that shoots towards the gas area, igniting the gas. The ignition mechanism is the most active part in the evolution of lighters and also the most complex in structure. Based on the characteristics of the ignition mechanism, lighters can be divided into six types: flint and steel wheel lighters, piezoelectric ceramic lighters, magnetic induction lighters, battery lighters, solar-powered lighters, and microcomputer lighters. The gas used in lighters is mainly flammable gas; early lighters mostly used kerosene; nowadays, butane, propane, and liquefied petroleum gas are more commonly used. These gases are pressurized and filled into the gas tank. Once released into the air, they absorb heat, vaporize, and expand rapidly, making them extremely easy to ignite.

[0003] Chinese Patent Publication No. CN216384256U discloses a high-efficiency windproof lighter, including an oil reservoir with a fixed cover on top. A hinged flap is connected to one side of the fixed cover. A windproof shell is installed at one end of the fixed cover, and an igniter is mounted on the outer side of one side of the windproof shell. An air inlet is provided on the upper outer wall of the windproof shell, and a guide plate is installed on the inner side of the air inlet. A combustion port is located on the top of the windproof shell. This high-efficiency windproof lighter's windproof shell provides excellent wind protection, making it convenient for outdoor use. The air inlet guides air upwards, preventing it from affecting the flame. It also ensures airflow at the combustion port, guaranteeing sufficient oxygen supply for stable combustion. Furthermore, the anti-slip curved surface and thumb groove ensure a comfortable grip during use, preventing accidental slippage.

[0004] Existing lighters mostly have a one-piece casing, which is not easy to disassemble, making it inconvenient to refill the lighter or change the flint. At the same time, it is difficult to know the usage of kerosene and flint, and it is not possible to replace the flint and add kerosene in time, which brings inconvenience to the use of the lighter. Furthermore, the steel ball holder and pendulum are made of metal, which are easily worn and damaged, and the material of the windproof wall cannot be changed, which reduces the playability. Therefore, we propose a kerosene lighter. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6A kerosene lighter includes a lighter housing 1. An observation port 6 is provided on the upper right side of the lighter housing 1. A fixing plate 5 is installed above the observation port 6. A flint hole 14 is provided inside the fixing plate 5. An observation slit 15 is provided on the right side of the flint hole 14. An externally threaded cylinder 16 is installed below the flint hole 14. An internally threaded cylinder 9 is installed below the externally threaded cylinder 16. A spring 11 passes through the internally threaded cylinder 9. A limiting post 18 is installed below the spring 11. The shape and dimensions of the limiting post 18 partially match the shape and dimensions of the internal internal part of the internally threaded cylinder 9, and the limiting post 18 can move within the internal internal part of the internally threaded cylinder 9. A limiting plate 10 is installed below the limiting post 18. The limiting plate 10 is frustoconical. The structure includes an observation port 6 with a transparent ring 7 installed inside. A fixing plate 5 is fixedly connected to an external threaded cylinder 16, which communicates with the flint hole 14. An internal threaded cylinder 9 is threadedly connected to the external threaded cylinder 16. The transparent ring 7 is detachably connected to the observation port 6 via the fixing plate 5 and the internal threaded cylinder 9. The shape and dimensions of the transparent ring 7 match the shape and dimensions inside the observation port 6. By setting up the observation port 6 and its internal transparent ring 7, the dryness of the oil-absorbing sponge inside the oil tank can be observed through the transparent ring 7, thus indicating the remaining amount of kerosene and facilitating timely replenishment. An observation slit 15 is also provided to expose a portion of the flint. The flint is used to promptly determine if it needs replacement. The lighter housing 1 has an internal mounting groove 17 at its bottom, inside which a base plate 12 is installed. The base plate 12 has a limiting hole 13 inside; the shape and size of the limiting plate 10 match the shape and size of the limiting hole 13. The shape and size of the base plate 12 match the bottom shape and size of the lighter housing 1, and the base plate 12 is detachably connected to the lighter housing 1 via the mounting groove 17, the limiting plate 10, and the limiting hole 13. The detachable base plate 12 facilitates easy removal for adding or replacing the flint. Furthermore, the quick-release structure of the base plate 12 is simple to manufacture, low in cost, and easy to use. The ball bearing latch 2 is designed... On the left side of the lighter housing 1, and on the upper left side of the lighter housing 1, a pendulum 3 is movably installed; both the ball bearing latch 2 and the pendulum 3 are made of agate; by using agate for the ball bearing latch 2 and the pendulum 3, the hardness of the ball bearing latch 2 and the pendulum 3 is greatly improved, preventing wear and damage to the ball bearing latch 2 and the pendulum 3, while also being aesthetically pleasing and crystal clear. A windproof wall 4 is installed in the upper center of the lighter housing 1, and four mounting bolts 8 are installed at the bottom inside the windproof wall 4; the windproof wall 4 is detachably connected to the lighter housing 1 through the mounting bolts 8; by setting a detachable windproof wall 4, it is easy to disassemble and replace the windproof wall 4 with different styles or materials, increasing the selling point and playability of the lighter.

[0030] Working Principle: When using this kerosene lighter, firstly, the high hardness of the agate-material steel ball holder 2 and pendulum 3 ensures that they are not easily worn or damaged during operation. Secondly, when it is necessary to replace the windproof wall 4 with a different shape and material, it can be removed and replaced using the mounting bolts 8. Thirdly, the dryness of the oil-absorbing sponge inside the lighter housing 1 can be seen through the transparent ring 7 inside the observation port 6, allowing for timely addition of kerosene. Fourthly, as the flint is used, the spring 11 pushes the flint upwards using its own elasticity. When the flint is almost used up, the bottom of the flint can be seen through the observation slit 15 for easy replacement. Finally, when it is necessary to replace the flint... When adding kerosene or lighter fluid, press the limiting plate 10 inward. The limiting post 18 retracts into the inner threaded cylinder 9, causing the limiting plate 10 to exit from the limiting hole 13. Then, push the bottom plate 12 to the right, causing it to exit from the mounting groove 17. The bottom plate 12 can then be removed for adding fluid. Afterward, pull the spring 11 out from the inner threaded cylinder 9, and insert a new flint into the inner threaded cylinder 9, extending it out from the flint hole 14. Finally, reinsert the bottom plate 12 into the mounting groove 17. The spring 11, through its own elasticity, pushes the limiting plate 10 back into the limiting hole 13, locking the bottom plate 12 in place. This is the working principle of this kerosene lighter.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
