Description

Safety-covered liquid fuel burning device

The present invention primarily discloses a combustion apparatus, and more particularly a liquid fuel combustion apparatus having a safety cover.

Generally, existing fuel combustion devices are classified into two types: direct combustion and use of wicks. If the fuel is flammable, it can be ignited without the need for a wick in an open flame. Commonly used as a raw alcohol fireplace burner. Biomass alcohol fireplace burner is usually a stainless steel container with open opening at the top. It can be ignited directly after adding alcohol. However, since the fuel is flammable, in addition to the difficulty of controlling the flame scale, the combustion will be carried out in the container, except for the formation. In addition to the safety problem of scalding, the heat must be waited until the flame is completely extinguished and the container is cooled before the fuel can be filled. Since the residual flame is often not noticeable at the bottom of the container, the user is likely to be dangerous when filling. Some modified bio-alcohol fireplace burners control combustion, and some designs use flammable fuels, but they do not ignite directly when used. Instead, they use ceramic fiber to control the scale of combustion, but also because of The combustion takes place in the container and forms a high heat. When the user fills the fuel, it is difficult to detect the residual fire in the container and the danger is likely to occur. However, if the fuel is nonflammable, the fuel must be ignited via the wick. The most common type of flaming device is a luminaire. It is common to install a high temperature resistant open disk on the fuel container, and place a wick of cotton fiber in the disk so that one end of the wick naturally hangs into the fuel cup. In this way, the cotton fiber wick can absorb the fuel in the fuel cup by capillary phenomenon, and the wick can volatilize the fuel against the end of the fuel container, and the volatile oil and gas can be burned when the top of the wick is ignited by the flame. Lamps made by the above principles are widely used and can be used as lighting, aesthetics or atmospheres, such as oil lamps used in general religious circles, as well as heating alcohol lamps used in medical or chemical laboratories. The principle is the same, the only difference is that the fuel is replaced by flammable alcohol, and the wick is used to control the combustion scale. For example, the existing alcohol lamp uses a closed type container filled with alcohol, and a cotton fiber as a wick is placed at one end of the container and placed at the other end of the container, and one end of the wick can absorb the alcohol in the container by capillary The phenomenon is that the alcohol is volatilized from the other end, and the alcohol can be burned after being ignited by the flame. Also, the existing fuel-using lamps use a closed container like an alcohol lamp.

Please refer to the "OIL LAMP WITH CERAMIC DIFFUSER" patent of U.S. Patent No. 6,555,069, which is an oil lamp with a ceramic diffuser in which a wick is placed in a closed container, one end of the wick is placed in the container and the other end is placed in the container. Outside the container, the wick is fixed to the opening of the container by a ceramic diffuser. The wick is disposed at one end of the container to absorb the fuel and is transported to the other end via capillary action for the user to ignite, thereby finally achieving the illumination effect.

However, the oil lamp adopting the above structure must be filled with the ceramic diffuser together with the wick when the fuel is filled, and then the fuel can be filled. If the fuel remains in the container when the wick is taken out, the fuel remaining in the wick is easily dripped. Outside the container. Placing a soft wick into a container after filling the fuel often causes operational inconvenience. When filling the fuel, the flame must be extinguished and wait for the ceramic diffuser to be completely cooled before the fuel can be filled. The ceramic diffuser can not be picked up and filled immediately after the wick is just burned. At the same time, the use of the common wick structure can not effectively insulate the heat into the container, so the flame scale cannot be increased. If the flame scale is increased, the fuel will be heated, and the fuel will be in danger if it is heated beyond the flash point.

In view of the above-described deficiencies in the conventional structure, the inventors have invented a safely covered liquid fuel burning apparatus which overcomes all of the disadvantages of the above-mentioned conventional structure.

The main purpose of the liquid fuel burning device with safety cover of the present invention is to provide a combustion device comprising a fuel container, a combustion device and a safety cover, the fuel container is provided with a receiving space and a liquid for filling and observing The opening of the fuel, the opening communicates with the inner side and the outer side of the accommodating space, the combustion device includes a wick, the wick includes a bottom end and a top end, the bottom end of the wick is inserted in the accommodating space, and the top end of the wick is disposed at the opening. The safety cover comprises a movable member, and two ends of the movable member respectively form a pivoting portion, wherein the two pivoting portions are respectively pivoted at the opening, and the movable member is selectively opposite to the fuel between the closed position and the raised position. The container pivots, and the movable member forms a shielding portion between the two pivoting portions. When the movable member is in the closing position, the shielding portion of the movable member shields the opening, and when the movable member is in the raised position, the shielding portion of the movable member Cover the wick and keep away from the opening, because the movable part will cover the wick when it is lifted, in addition to avoiding the user's improper operation and igniting the wick, maintenance use External security, providing a large area of filling port, allowing users to conveniently outside filling, and can clearly observe the fuel level in the filling process, and will not lead to over-fill the fuel spill. Moreover, it is not necessary to take out the wick during the whole operation, and it is not necessary to contact the high temperature zone and contact with the fuel, thereby greatly improving convenience and safety.

A secondary object of the present invention is to provide a fuel container comprising a safety seat, the fuel container comprising a fixing seat, the fixing seat being disposed in the opening of the fuel container, the fixing base comprising a first clamping member and a second clamping member Holding the first clamping member and the second clamping member between the two side walls, the first clamping member and the second clamping member are opposite to each other, and the first clamping member and the second clamping member are clamped Between the bottom end and the top end of the wick, the fixing seat and the movable member form a double-layer heat insulation design. Since the double-layer heat insulation design and the flame combustion are located outside the container, the fuel in the container can be kept at a low temperature to ensure a large combustion scale when the fuel is large. No overheating, even in the crosswind environment, the wick is designed in the concave middle part of the top surface of the device, which can reduce the flame from being tilted by the side wind and directly contact the top cover of the container. The top cover and the base are combined in a small area contact manner, in practical application. The high temperature formed by the flame is only present on the top cover, and the top cover is a thin metal piece, which is easy to exchange heat with the surrounding air by convection, reduces heat accumulation, and can effectively prevent heat transfer from being transmitted into the container. When the burn to be filled, the user can clearly feel the flip cover operating temperature, high temperature inside the container to avoid danger at the time of filling. This design can greatly improve the safety of use.
