Description

Technical Field

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

[0002] A lighter is a small fire-making device. Its main purpose is to make fire and smoke. It is also used for cooking and other fire-making activities. The main components of a lighter include an ignition mechanism and a gas storage box. When the ignition mechanism is activated, sparks will burst out and shoot towards the gas area to ignite the gas. According to the characteristics of the ignition mechanism, lighters can be divided into many types, such as flint steel wheel lighters, piezoelectric ceramic lighters, magnetic induction lighters, battery lighters, solar lighters and microcomputer lighters. The gas used in lighters is mainly combustible gas, such as butane, propane, etc. These gases are stored in the fuel chamber of the lighter in the form of compressed gas. In addition, some lighters use liquid fuels, such as gasoline, alcohol, etc. These liquid fuels enter the fuel supply system through small holes in the fuel chamber.

[0003] The internal accessories of the lighter are mainly shielded and protected by a metal shell. For example, the patent number disclosed on the China Patent Network is: 202020803653.4, and the patent name is: Kerosene lighter, including a fuel tank, an oil wick and an ignition mechanism. One end of the oil wick is the ignition end above the fuel tank, and the other end is the oil suction end. The ignition mechanism is arranged in the fuel tank and is located near the top of the fuel tank near the ignition end. The fuel tank is separated into a storage area and a consumption area. The consumption area is close to the oil wick and has a smaller volume than the storage area. The oil suction end extends into the consumption area. The fuel tank is located between the storage area and the consumption area and is provided with a closing component that controls the on and off of the two. The closing component is located outside the fuel tank and is provided with an operating part. By adopting the above scheme, the utility model provides a kerosene lighter that avoids kerosene waste and reduces the number of kerosene refills.
