Liquid fuel burner with safety cover

Abstract

The liquid fuel combustion device with a safety cover of the present invention includes a fuel container, a combustion component and a safety cover, the fuel container is provided with an accommodating space and an opening for filling and observing the liquid fuel, and the combustion component includes a wick , the two ends of the wick are respectively located in the accommodating space and the opening, the safety cover includes a movable part, the two ends of the movable part respectively form a pivot part, and the two pivot parts are respectively pivotally arranged in the opening, and the movable part Selectively pivoting relative to the fuel container between the cover position and the lift position, the movable part forms a shielding part between the two pivoting parts, and when the movable part is in the covering position, the shielding part of the movable part covers Opening, when the movable part is in the raised position, the shielding part of the movable part covers the wick and stays away from the opening, which is convenient for operation and improves safety.

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.
