DETAILED DESCRIPTION

[0020] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples.

[0021] As shown in Figure 1 Embodiment one: the embodiment includes a combustion cover and a gasification furnace head, the gasification furnace head includes an electric preheating core, a heat transfer inner cylinder and a heat transfer outer cylinder. The electric preheating core is located in the heat transfer inner cylinder, and the electric preheating core is powered by an external power supply. The heat transfer inner cylinder is inserted into the heat transfer outer cylinder, and the heat transfer inner cylinder and the heat transfer outer cylinder form a sealed cavity; the sealed cavity is connected with a fuel inlet pipe and a fuel outlet pipe; the fuel enters the sealed cavity through the fuel inlet pipe and is sprayed out from the fuel outlet pipe, and complete gasification of the fuel is achieved during the whole flow process. Since the structure of the gasification furnace head is very simple, the electric preheating core, the heat transfer inner cylinder and the heat transfer outer cylinder can be made very small, so the volume of the whole gasification furnace head is very small, the required heat for gasification is not high, and the fuel can be preheated and gasified in a short time, the preheating time is short, and the gasification speed is fast.

[0022] The combustion cover is arranged on the outside of the heat transfer outer cylinder, the combustion cover has an annular cavity, the annular cavity of the combustion cover is connected with the fuel outlet pipe, and the inside of the combustion cover is provided with gas injection combustion holes, and the flame of the gas injection combustion directly acts on the heat transfer outer cylinder.

[0023] In the embodiment, the gasification furnace head is arranged at the middle of the combustion cover, which can well recover heat and can turn off the power supply of the electric preheating core after combustion, thereby saving energy.

[0024] The gasification combustion furnace further includes an adjusting valve, an inlet end of the adjusting valve is communicated with the fuel outlet pipe, and an outlet end of the adjusting valve is communicated with the annular cavity of the combustion cover. The adjusting valve is used for adjusting the fuel inlet amount, so as to adjust the flame size. The gasification combustion furnace further includes a gas mixing valve, the gas mixing valve is located downstream of the adjusting valve, one end of the gas mixing valve is communicated with the outlet end of the adjusting valve, and the other end of the gas mixing valve is communicated with the annular cavity of the combustion cover. The gas mixing valve is used for adjusting the gas mixing ratio, so that different fuels can find a suitable gas mixing ratio, thereby ensuring that the fuel is burned more fully.

[0025] As shown in Figure 2 Embodiment two: different from embodiment one, the embodiment cancels the adjusting valve and the gas mixing valve, adds a fan and a two-fluid, and divides the annular cavity of the combustion cover into an upper cavity and a lower cavity. The inlet end of the fan is connected with the fuel outlet pipe, the outlet end of the fan is communicated with the lower cavity of the annular cavity of the combustion cover, the upper cavity and the lower cavity of the annular cavity are separated by a partition plate, the partition plate is provided with communication holes, the communication holes on the partition plate close to the fan are arranged at a low density, and the communication holes on the partition plate away from the fan are arranged at a high density.

[0026] In the embodiment, the two-fluids are located upstream of the fuel inlet pipe. The two-fluids can provide a mist of fuel, which has less volume than liquid fuel entering the sealed cavity between the heat transfer inner cylinder and the heat transfer outer cylinder, and thus has a faster vaporization speed and is less likely to coking in the sealed cavity.

[0027] In both the first and second embodiments, the combustion cover has a "bowl" shape structure with a large diameter at the upper end, a small diameter at the lower end, and an arc on the side wall. The "bowl" shaped combustion cover can make the jet of the burner tilt upward, forming a favorable flame state for the heated appliance.
