Description

Not hot burning device

The invention mainly discloses a combustion device, especially an overheating combustion device.

Please refer to the patent case of "Combination Structure of Ornamental Fire" in Chinese Patent No. I625493, which is a combination structure of ornamental fire, which includes an accommodating device, a combustion device and a fixing device. The accommodating device includes a fuel container, a top cover and a partition The heating element, the accommodating portion is provided in the fuel container and connected to the top cover, the filler hole and the first positioning groove are penetrated through the top cover and communicate with the accommodating portion, and the heat insulating element is connected to the top cover different from the accommodating portion At one end, the second positioning groove penetrates the top and bottom sides of the heat insulation and communicates with the first positioning groove. The second end of the combustion device is inserted into the accommodating portion through the second positioning groove and the first positioning groove. The holding surface and the second clamping surface respectively correspond to and clamp the two side surfaces of the combustion device.

The main function of the above-mentioned combined structure is for viewing, and the viewing effect expected by the user is to see the pattern of stable combustion of flame. However, the combustion device of the above combined structure is not covered by objects. If it is used outdoors, the preset flame pattern cannot be maintained when there is wind, resulting in a decrease in the viewing effect or direct flame contact with the container to accumulate high temperature.

Especially in the state where the flame is burning in the glass container, the best viewing effect can be obtained. The fuel container of the above combined structure is usually made of glass material. To obtain a better viewing effect, the ideal method is to increase the height of the fuel container, so that The glass fuel container can surround the flame. However, the temperature generated when the flame is burning will heat the surrounding air, causing the temperature of the air around the flame to rise and flow upward. When the air around the flame is lost, it will form a low pressure. The air near the wall of the fuel container will flow to the flame, adjacent to the fuel container When the position of the wall surface is under low pressure due to the air flowing away, only the air near the opening of the fuel container can be replenished into the fuel container, but the air at the opening of the fuel container is the air that has been heated by the flame, and the hot air returns to The convection method in the fuel container will continue to accumulate heat and cause the temperature of the fuel container to increase, which may not only cause the risk of scalding of the user, but the high temperature of the fuel accumulates and the risk of flashover is likely to occur. And the flow of hot air backflow will disturb the air around the flame and cause excessive flame disturbance, reducing flame visibility. At the same time, the lower height of the glass of this combined structure is beneficial to heat dissipation, but it is less shielded by the flame when it is blown by the ambient air flow. In addition to not effectively preventing the ambient air flow from affecting the flame shape, the flame is offset by the wind pressure and the flame around the container is heated by the high temperature of the flame. However, if the height of the glass is increased to improve the windproof effect, it will not only aggravate the phenomenon of hot air forming a reflux, but also make the situation of accumulated high temperature more serious. Especially when the scale of combustion is increased, the container and fuel will accumulate high temperature, which may easily cause burns or even cause the fuel to heat up and cause the temperature to exceed the flashover point and cause the risk of flashover.

In view of the lack of the above-mentioned conventional structure, the inventor has designed an overheating combustion device, which can overcome all the disadvantages of the above-mentioned conventional structure.

A bottom 32 is provided at one end of the outer cover 30 in the vertical direction and is different from one end of the bottom 32 There is a top 33, and the accommodating space 31 extends from the bottom 32 to the top 33.

The outer cover 30 is provided with a first through hole 34, one end of the first through hole 34 communicates with the accommodating space 31 and a different end communicates with the outside world, the maximum height of the first through hole 34 in the vertical direction is less than the The height of the top end 25 in the vertical direction, the maximum height of the first through hole 34 in the vertical direction in this embodiment is smaller than the height of the opening 23 in the vertical direction.

The outer cover 30 has an integrally formed structure. The outer cover 30 includes a side wall 35 and a bottom plate 36. The side wall 35 is in the shape of a circular tube and extends in a vertical direction. The side wall 35 extends from the bottom 32 to the top 33. The bottom plate 36 is connected to the side wall 35, the bottom plate 36 is adjacent to the bottom 32 and extends in a horizontal direction, the first through hole 34 penetrates the bottom plate 36, the outer cover 30 is transparent, and the material of the outer cover 30 is glass.

Three supporting legs 37 are protruded from a side of the bottom plate 36 different from the top 33, and the three supporting legs 37 are arranged around the first through hole 34 at equal intervals. The three supporting legs 37 can be placed on a plane, and the fuel container 21 can pass through the first through hole 34 and be placed on a plane.

The combustion device 10 achieves the effects of heat dissipation and flame stabilization through the above structure. When the burner 10 is used, after the burner 20 is ignited, the air above the wick will rise due to heat. After the low pressure is formed around the wick, in order to balance the pressure, the burner 20 and the first The hole 34 introduces outside air to form a circulation. Through the above-mentioned thermal convection effect, the high-temperature air in the upper part of the burner 20 is kept in an ascending state and is not likely to cause backflow. The air in the accommodating space 31 is convected from bottom to top The flow direction helps maintain a stable flame shape, so that the combustion device 10 provides a good visual effect.

Moreover, because the high-temperature air heated by the flame reduces the backflow, the high-temperature air can be reduced from contacting the outer cover 30, so that the temperature of the outer cover 30 is not too high, and the user's suspicion of burns is greatly reduced. Moreover, the design of the combustion device 10 that introduces air from below the burner 20 will contact the burner 20 when the air enters the accommodating space 31, and the structure adopted by the combustion device 10 may also provide continuous heat dissipation for the burner 20 As a result, the fuel container 21 is maintained at a relatively low temperature.

When the combustion device 10 is placed outdoors and is blown by a lateral wind in the horizontal direction, a backflow will be formed in the depression, and a part of the lateral wind will be blocked by the position of the outer shell 30 near the top 33 and enter the downward In the accommodating space 31, since the blades can guide and restrict the flow direction of the cooling air, the upward air flow inside the combustion device 10 will cancel or weaken the backflow formed by the blown side wind, which can greatly reduce the side wind The impact on the combustion device 10 does not cause high temperature to directly contact the housing to reduce the risk of high temperature accumulation. The combustion device 10 can be used normally and maintain flame visibility and shape even when there is wind outdoors.
