[0023] The present application provides a burner, wherein the fuel used in the burner is generally gas, wherein the gas can be a mixed gas capable of combustion and / or combustion support, and the fuel can also be a liquid fuel with fluidity. The following embodiments of the present application will be described with the burner using gas as an example. Referring to Figures 1 to 2 , Figure 1 is a structural schematic diagram of an embodiment of the burner provided by the present application, Figure 2 is Figure 1 is an explosion schematic diagram of an embodiment of the burner in the embodiment, as Figures 1 to 2 shown, the burner 10 includes a body assembly 100 and an injection assembly 200. The body assembly 100 is provided with a combustion surface, a receiving cavity 122, and a flow guide opening 121 communicating with the receiving cavity 122. The injection assembly 200 is provided with an injection flow channel, one end of the injection flow channel communicates with the flow guide opening 121, and the injection assembly 200 is located on the side of the receiving cavity 122 away from the combustion surface. Wherein, the other end of the injection flow channel extends along a first direction, the included angle between the first direction and a second direction is greater than zero and less than 180°; the second direction is from the flow guide opening 121 to the combustion surface. The flow guide opening 121 is arranged corresponding to the peripheral region of the combustion surface.

[0024] It can be known that the injection flow channel guides the gas to the accommodating cavity 122 through the flow guide port 121, and the gas is combusted on the combustion surface. One end of the injection flow channel is in communication with the flow guide port 121, and the other end of the injection flow channel extends in the first direction, and the included angle between the first direction and the second direction is greater than zero and less than 180°; the second direction is from the flow guide port 121 to the combustion surface. It can be known that, taking one end of the injection flow channel as a fixed point, the included angle between the other end of the injection flow channel and the second direction is greater than 0 and less than 180°. For example, taking the second direction as the Y axis, and taking any point between (-y, +y) as a moving point, wherein the direction from the origin to the moving point is the first direction, and taking one end of the injection flow channel as the origin and the other end of the injection flow channel after extending in the first direction as the moving point. Wherein, the flow guide port 121 is arranged corresponding to the peripheral region of the combustion surface, for example, when the combustion surface is arranged as a rectangular combustion surface, the flow guide port 121 can be located or close to the position corresponding to the included angle of the rectangular combustion surface, or the flow guide port 121 can be located or close to the position corresponding to the edge of the rectangular combustion surface; when the combustion surface is arranged as a circular combustion surface, the flow guide port 121 can be located or close to the position corresponding to the edge of the circular combustion surface. That is, when the combustion surface is a regular figure, the position of the flow guide port 121 is not the position corresponding to the center of the combustion surface. Through the above-mentioned manner, the projection of the injection flow channel on the combustion surface overlaps a small area of the combustion surface, thereby reducing the negative influence of the high-temperature combustion surface on the injection coefficient of the injection flow channel, improving the injection capacity of the burner 10, and further improving the combustion performance of the burner 10.

[0025] The burner 10 of the embodiment comprises a body assembly 100 and an injection assembly 200, the injection assembly 200 is located on the side of the accommodating cavity 122 away from the combustion surface, so that the combustion surface and the injection flow channel are spaced apart, thereby reducing the negative influence of the high-temperature combustion surface on the injection coefficient of the injection flow channel, and improving the combustion performance of the burner 10; in addition, the other end of the injection flow channel extends in the first direction, the included angle between the first direction and the second direction is greater than zero and less than 180°, the second direction is from the flow guide port 121 to the combustion surface, and the flow guide port 121 is arranged corresponding to the peripheral region of the combustion surface, so that the projection of the injection flow channel on the combustion surface overlaps a small area of the combustion surface, thereby further reducing the negative influence of the high-temperature combustion surface on the injection coefficient of the injection flow channel, and further improving the combustion performance of the burner 10.

[0026] In other embodiments, the flow guide port 121 is arranged at a position corresponding to the periphery of the accommodating cavity 122, that is, the position of the flow guide port 121 is not the position corresponding to the center of the accommodating cavity 122.

[0027] Optionally, the included angle between the first direction and the second direction is greater than 80° and less than 120°, for example, 80°, 90°, 95°, 100°, 120°, etc. The embodiment can optimize the layout of the injection assembly while ensuring a certain distance between the combustion surface and the injection assembly 200.
