Combustion device to prevent accumulation of oil and gas

Abstract

The invention discloses a combustion device capable of preventing oil gas accumulation. The combustion device comprises a body, a lamp wick and a metal foaming body, a fuel chamber is formed in the body, one end of the lamp wick is held in the fuel chamber, and the metal foaming body surrounds the lamp wick along with the transverse direction of the lamp wick and is mounted between the body and the lamp wick. The metal foaming body is capable of absorbing the oil gas from the fuel chamber and volatilizing the oil gas to the outside of the fuel chamber in a fixed speed, so that a back-draft phenomenon occurred in using the combustion device due to excessive oil gas in the fuel chamber is avoided, and meanwhile, the metal foaming body is flame retardant, the oil gas absorbed by the metal foaming body is avoided from burning in the metal foaming body, and the danger caused by that the flame returns to the fuel chamber is effectively avoided.

Description

technical field [0001] The present invention mainly discloses a combustion device, especially a combustion device for preventing accumulation of oil and gas. Background technique [0002] Generally, the existing lamps are provided with a high-temperature-resistant plate on the fuel cup, and a wick made of cotton thread is placed in the plate, so that one end of the wick naturally hangs into the fuel cup, so that the cotton wick Capillarity absorbs the fuel in the fuel cup, and the end of the wick opposite to the fuel cup can volatilize the fuel, and when the top of the wick is ignited with a flame, the volatilized oil and gas can be burned. Lamps made of the above principles are widely used and can be used for lighting, aesthetics or creating atmosphere, such as oil lamps used in general religious circles, and alcohol lamps used in medicine or chemical circles. The principles are the same, but the difference is The only thing is to replace the fuel with alcohol. [0003] T...

Problems solved by technology

[0005] However, when using an existing oil lamp or alcohol lamp that uses a closed container to fill fuel oil or alcohol, the fuel oil or alcohol will volatilize naturally in the container, causing the volatilized oil vapor or alcohol to accumulate in the airtight space in the closed container. Or when the alcohol lamp burns, it is easy to cause the oil gas or volatile alcohol in the container to burn due to the high temperature, which will eventually lead to a strong combustion reaction, which is quite dangerous

[0006] Moreover, the container and the wick cannot be completely tightly combined when they are combined, and there must be a gap between the wick and the container. After a certain amount of volatilized oil gas or alcohol accumulates in the container, it will flow out from the gap between the wick and the container. , if the oil lamp or alcohol lamp is in a burning state, the oil and gas flowing out of the gap will be ignited at the same time, and finally the flame will burn back into the container through the gap between the wick and the container
