In the prior art, the inner end of the combustion cotton rope is directly inserted into kerosene for fuel absorption, which has a large oil drawing speed, but also speeds up the evaporation of kerosene in the non-ignition state. Moreover, when the combustion cotton rope needs to be replaced, the whole combustion cotton rope including the internal oil drawing section needs to be replaced, which is inconvenient to operate and causes unnecessary waste.

The slow-release oil introduction assembly 3 is used to slowly guide the fuel in the fuel tank 11 to the combustion assembly 5. Compared with the method in which the inner end of the combustion assembly 5 directly extends into the fuel tank 11, the slow-release oil introduction assembly 3 is provided. The oil introduction component 3 slows down the speed at which fuel is introduced from the fuel tank 11 to the combustion component 5, reduces the speed at which the fuel volatilizes, and the speed at which the combustion component 5 burns and consumes fuel is greater than the speed at which the oil is introduced, so that each time the combustion component 5 is ignited, the combustion head will automatically go out after burning for a certain period of time due to insufficient fuel supply, thereby achieving the effect of a single combustion for a certain period of time.
