Description

Combustion device with radiating heat insulation pad

The invention mainly discloses a combustion device, especially a combustion device with a heat dissipation and heat insulation pad.

Generally, existing fuel combustion devices are divided into two types: direct combustion and the use of a wick. If the fuel is flammable, the flame can be ignited without an wick. Common is the biomass alcohol fireplace burner. The biomass alcohol fireplace burner is usually a stainless steel container with an open opening at the top. It can be ignited directly after adding alcohol, but because the fuel is flammable, in addition to the difficulty of controlling the flame scale, the combustion will proceed in the container, except for the formation High heat is often derived from the safety problem of scald use. After burning, you must wait until the flame is completely extinguished and the container cools before you can fill the fuel. Because the residual flame is often difficult to detect at the bottom of the container, the user is likely to be dangerous when filling. Some modified biomass alcohol fireplace burners are designed to control combustion, while some are designed to use flammable fuels, but they are not directly ignited when used, but use ceramic fiber (ceramic fiber) to control the scale of combustion, but also because Combustion will proceed in the container and form high heat. When the user fills the fuel, it is not easy to detect the residual fire in the container and it is prone to danger.

Another type of fuel burning device uses non-flammable fuel. If the fuel is nonflammable, the fuel must be ignited through the wick. However, if the fuel is heated beyond its flash point, the non-flammable fuel will become flammable due to the volatilization of the fuel and can be ignited without going through the candle wick. Therefore, when the flame retardant fuel is heated beyond its flash point, it is still easy to cause danger in use.

Please refer to the US Patent No. 9476586 "MODULAR WICK HOLDER" patent case, which discloses a modular candle wick fixing device, which includes two bracket units and at least one adjustment member, the bracket unit includes a first side plate And a second side plate, an end of the first side plate away from the second side plate is formed with a first connection portion, an end of the second side plate away from the first side plate is formed with a second connection portion, and the second connection portion of the bracket unit is connected to another A first connection portion of a bracket unit, the bracket unit further has a clamping plate, the clamping plate includes a clamping portion, a clamping space is formed between the two clamping portions, and an adjusting member is located between the two clamping plates . The wick is installed on the fuel container through the above-mentioned fixing device. The above-mentioned fixing device is processed and formed by sheet metal bending. There is a gap at the cutting and bending point, and the fixing device is provided with a perforation for fuel filling, forming a semi-open structure of combustion Device.

Because the heat energy is transferred by conduction convection and radiation, when the combustion device burns, the flame generates high heat, which causes the air surrounding the flame to expand and form a density difference with the ambient air, thus generating buoyancy to flow upward. At the same time, the surrounding air flows to the low-pressure area formed by the rise of hot air to form convection. High temperature convection, so the high temperature formed by the combustion device under the flame in the fuel tank is mostly caused by the conduction and accumulation of radiant heat. The fuel tank must be kept at the flash point to ensure safe use. The traditional semi-open or simple type fuel combustion device has a small combustion scale, so it generates small heat and dissipates heat quickly, even if it is used for a long time, so as not to cause the fuel to exceed the flash point. When the scale of combustion increases, the accumulated amount of conduction and radiant heat is considerable. If the ambient temperature is high or the side wind causes the high temperature of the flame to lead to the fuel tank to cause unfavorable heat dissipation, the risk of flashover caused by the accumulated high temperature is easy to occur. Another possibility is that when the temperature of the oil in the semi-open or open oil tank is too high, even if the flash point is not reached, if the high-temperature oil is accidentally tipped over, it will also be dangerous.

In view of the lack of the above-mentioned conventional structure, the present inventor is committed to designing a combustion device with heat dissipation and heat insulation pads, which can overcome all the disadvantages of the above-mentioned conventional structure.

The main purpose of the combustion device with heat dissipation and heat insulation pad of the present invention is to provide a combustion device including a fuel tank, a candle wick and a heat dissipation heat insulation pad.

The material of the heat insulation layer is non-metal, and the material of the heat dissipation layer is metal. By reducing and blocking conduction And the accumulation of radiant heat keeps the fuel at a relatively low temperature, and the combustion device improves safety through the above structure.

The area of the heat insulation layer is smaller than the area of the heat dissipation layer. The heat insulation layer has suspended portions at the top and bottom, which can increase the heat dissipation area and improve the heat dissipation efficiency.

The inner periphery of the heat insulation layer adjacent to the candle wick abuts against the candle wick. The heat insulation layer reduces the heat conduction and forms a seal around the candle wick. The closed fuel tank can prevent the oil and gas from volatilizing and contacting the flame, and can also greatly reduce the risk of dangerous leakage of dumped fuel.

When the burning device 10 is used, the accommodating groove 211 needs to contain fuel 90. The wick 30 can absorb the fuel 90 by capillary action, and the flame generated by igniting the wick 30 to burn the fuel 90 can mainly be used for viewing. The fuel 90 will inevitably generate high temperature when it burns. In order to prevent the high temperature of the fuel 90 from burning through the tank 21, the combustion device 10 can effectively prevent the temperature of the tank 21 and the fuel 90 therein from rising through the above structure.
