Description

Not too hot burner

The present invention mainly discloses a combustion device, especially a combustion device that is not overheated.

Please refer to the patent case of "Combination Structure of Ornamental Fire" of China Patent No. I625493, which is a combination structure of ornamental fire, which includes a containing device, a burning device and a fixing device. The containing device includes a fuel container, a top cover and a partition. The thermal element, the accommodating part is arranged in the fuel container and connected with the top cover, the filling hole and the first positioning groove are penetratingly arranged in the top cover and communicate with the accommodating part, and the heat insulating part is connected to the top cover different from the accommodating part At one end, the second positioning groove penetrates the top side and the bottom side of the heat insulator and communicates with the first positioning groove. The second end of the combustion device is inserted into the accommodating part through the second positioning groove and the first positioning groove. The holding surface and the second holding 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 flame burning stably. However, the combustor with the above-mentioned combined structure is not shielded by objects. If it is used outdoors, the preset flame pattern cannot be maintained when there is wind, resulting in reduced viewing effects or direct flame contact with the container to accumulate high temperatures.

The best viewing effect can be obtained when the flame burns in the glass container. The fuel container with the above-mentioned combined structure is usually made of glass. To obtain a better viewing effect, the ideal way is to increase the height of the fuel container to make The glass fuel container can surround the flame. However, the temperature generated when the flame burns will heat the surrounding air, causing the air around the flame to increase in temperature and flow upwards. After the air around the flame is lost, a low pressure will be formed. 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 is at a low pressure due to the air flowing away, only the air adjacent to 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 flows back to The convection method in the fuel container will continue to accumulate heat and cause the temperature of the fuel container to rise, which may not only cause the risk of burns to the user, but also the risk of flashing when the fuel is heated and accumulated high temperature. In addition, the flow of hot air will disturb the air around the flame, causing excessive flame disturbance and reducing flame visibility. At the same time, although the glass height of this composite structure is low, it is good for heat dissipation, but the flame shields less when it is blown by the ambient airflow. In addition to being unable to effectively prevent the ambient airflow from affecting the flame shape, the flame will be deflected by wind pressure and the container will be 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 backflow, but also make the accumulation of high temperature more serious. Especially when the scale of combustion increases, the container and fuel will accumulate high temperature, which will easily cause burns and even cause the fuel to be heated and the temperature will exceed the flash point and the risk of flashover will occur.

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

Regarding the technology, means and effects adopted by the present invention, two preferred embodiments are described in conjunction with the drawings as follows. These are for illustrative purposes only, and are not limited by this structure in the patent application.

1 to 4, which are the three-dimensional appearance view, three-dimensional exploded view, cross-sectional structure view, and use state view of the first embodiment of the overheated combustion device of the present invention. The combustion device 10 of the present invention includes a burner 20 and an outer cover 30; among them:

The burner 20 is composed of a fuel container 21 and a core 22. The upper end of the fuel container 21 is provided with an opening 23 along the vertical direction. The core 22 is provided with a bottom end 24 and a different bottom end. The top end 25 of the 24 is inserted into the fuel container 21 through the opening 23, and the top end 25 protrudes out of the fuel container 21.

The outer cover 30 is provided with an accommodating space 31, the burner 20 is provided in the accommodating space 31, and one end of the outer cover 30 along the vertical direction is provided with a bottom 32 and an end different from the bottom 32 is provided 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. The maximum height of the first through hole 34 in the vertical direction is smaller than the The height of the top end 25 in the vertical direction, and 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 is an integrally formed structure. The outer cover 30 includes a side wall 35 and a bottom plate 36. The side wall 35 is tubular and extends in a vertical direction. The side wall 35 extends from the bottom 32 to the top 33. 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 outer cover 30 is made of glass.

The three supporting feet 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 effect of heat dissipation and flame stabilization through the above structure. When the burning device 10 is in use, after the burner 20 is ignited, the air in the upper part of the candle wick will rise due to heat, and after a low pressure is formed around the candle wick, in order to balance the pressure, the burner 20 can be moved around 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 at the upper part of the burner 20 is kept in an ascending state and is not prone to backflow. The air in the accommodation space 31 is convective from bottom to top The flow direction helps maintain a stable flame shape, so that the combustion device 10 provides a good visual effect.

In addition, since the high-temperature air heated by the flame reduces backflow, it can reduce the high-temperature air 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. In addition, the combustion device 10 is designed to introduce air from below the burner 20, and when air enters the accommodating space 31, it will contact the burner 20. The structure of the combustion device 10 can 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 burning device 10 is placed outdoors and is blown by a horizontal side wind, a backflow will be formed in the recess, and a part of the side wind will inevitably be blocked by the position of the outer cover 30 near the top 33 and enter the In the accommodating space 31, since the blades can divert and restrict the flow direction of the cooling air, the upward air flow direction inside the combustion device 10 will be offset or weakened by the backflow formed by the blow-in side wind, which can greatly reduce the side wind The influence on the combustion device 10 prevents the high temperature from directly contacting the outer cover to reduce the risk of high temperature accumulation. The combustion device 10 can be used normally even when there is wind in the outdoors and maintain the visibility and shape of the flame.
