Liquid fuel combustion device with safety cover

Abstract

The invention provides a liquid fuel combustion device with a safety cover. The device comprises a fuel container, a combustion device and the safety cover, wherein the fuel container is provided with a storing space, and an opening for filling and observing the liquid fuel; the combustion device comprises a lamp wick; two ends of the lamp wick are respective positioned in the storing space and the opening; the safety cover comprises a moving part; pivoting parts are formed at two ends of the moving part and are respectively pivoted to the opening; the moving part is selectively pivoted relative to the fuel container between a closing position and an opening position; the moving part forms a shielding part between the two pivoting parts; when the moving part is in the closing position, the shielding part of the moving part shields the opening; when the moving part is at the opening position, the shielding part of the moving part shields the lamp wick and is far away from the opening; the operation is convenient, and the safety can be improved.

Description

technical field [0001] The invention relates to a combustion device, especially a liquid fuel combustion device with a safety cover. Background technique [0002] Generally, existing fuel combustion devices are divided into two types: direct combustion and use of wicks. If the fuel is flammable, it can be ignited with an open flame without a wick. Commonly used are bio-ethanol fireplace burners. Biomass alcohol fireplace burners are usually a stainless steel container with an open opening at the top, which can be ignited directly after adding alcohol. High heat often leads to safety issues such as easy burns. After burning, you must wait until the flame is completely extinguished and the container is cooled before filling the fuel. Since the residual flame is often difficult to detect at the bottom of the container, users may be dangerous when filling. Some improved biomass alcohol fireplace burners are designed to control combustion, and although some are designed to use...

Problems solved by technology

[0004] However, when the oil lamp with the above structure is filled with fuel, the ceramic diffuser and the wick must be taken out from the container before the fuel can be filled. If there is still fuel in the container when the wick is taken out, the remaining fuel from the wick will easily drip. outside the container

Putting the soft wick into the container after filling the fuel often causes inconvenience in operation

And when filling the fuel, you must first extinguish the flame and wait for the ceramic diffuser to cool completely before filling the fuel. You cannot directly pick up the ceramic diffuser and fill it right after the wick is burned.

At the same time, the common wick structure cannot effectively insulate the heat conduction into the container, so the scale of the flame cannot be increased. If the scale of the flame is increased, the fuel will be heated. Once the fuel is heated beyond the flash point, it will cause danger.
