Technical Field

[0001] The utility model relates to the technical field of lighters, in particular to a kerosene lighter. Background Art

[0002] Kerosene lighters are commonly used small fire-making devices, usually including a casing, an inner tank installed in the casing, a cotton core and an ignition mechanism. One end of the cotton core extends into the inner tank and contacts the kerosene, and the other end extends from the top of the inner tank as an ignition port. There are generally two common lighter models. One is to open the fire cover first, and then slide the fire wheel of the kerosene lighter with your fingers, and the ignition nozzle can ignite the fire; the other is to press the end of the fire cover away from the ignition nozzle by hand to open the fire cover. When the fire cover is opened, the fire wheel will slide, and then the ignition nozzle will ignite the fire. Such kerosene lighters generally have problems such as poor air tightness, low safety, and complicated operation. Therefore, developing a kerosene lighter with excellent air tightness, safety, durability, and easy operation is of great significance to improving user experience and safety. Utility Model Content

[0012] 1. High efficiency and airtightness: Since the inner end of the fire cover is provided with a hole for sealing the ignition port of the cotton core, when the lighter is not in use, the inner tank extends upward, and the cotton core at the top of the inner tank extends into the hole, which is equivalent to closing the ignition port, ensuring a tight closure between the inner tank cotton core and the body. This application can not only effectively prevent fuel volatilization and increase the use time, but also ensure the safety of the lighter when not in use.

[0013] 2. Safe and durable structure: The combination of the inner tank and the pull bolt adopts a threaded connection, which is not only strong and durable, but also can effectively discharge the air pressure in the inner tank to prevent fuel from overflowing due to excessive pressure. This design avoids oil spills and contaminating clothes, and also improves fuel endurance and safety during use.

[0014] 3. Simple operation: The lighter is easy to operate. Users only need to slide the pull bolt on the side of the shell down to the middle and then push it horizontally to the bayonet and position it to expose the ignition port of the inner cotton core. Then, slide the spark wheel to easily ignite it. When you need to turn off the fire, just move the pull bolt horizontally out of the bayonet, the spring will naturally extend to push the inner tank upward, and the inner tank will automatically turn off the flame.

[0029] When ignition is required, the user only needs to hold the casing and rotate the sealing cover 103 of the present application clockwise, and the sealing cover can drive the inner tank to rotate downward. When the ignition port of the cotton core of the inner tank is exposed from the flame outlet, stop rotating the sealing cover. Then, the sliding spark wheel can easily ignite the ignition port of the cotton core, and the flame is exposed from the flame outlet; when the fire needs to be turned off, only the sealing cover needs to be rotated counterclockwise, the middle step can push the inner tank upward, the cotton core is inserted into the hole of the fire cover, and the flame is automatically extinguished. The operation process is simple and quick.

[0030] When the user needs to refuel the inner tank, the user only needs to hold the casing and rotate the sealing cover 103 of the present application clockwise, and the sealing cover can drive the inner tank to rotate downward until the inner tank is brought out of the casing, and then hold the inner tank and continue to rotate the sealing cover, screw the sealing cover out of the inner tank, and the fuel can be poured into the inner tank. After filling the oil, tighten the inner tank and the sealing cover, put the inner tank into the casing, and continue to screw the sealing cover.
