the air-conditioning device comprises a shell 1, an end cover 2, an air duct 3, a cyclone sheet 4, a cyclone sheet body 41, an air guide groove 42, a central hole 43, a spray head 5, an air pipe 6, an air groove 61 and an air inlet 7.

Detailed Description

The present invention will be described in further detail with reference to the drawings and the following detailed description.

Referring to fig. 3, the present embodiment provides a novel high-pressure low-flow energy-saving burner, which includes a housing 1, an end cap 2, a wind pipe 6, a gas pipe 3, an ignition electrode, a nozzle 5, and an air inlet 7.

The end cover 2 is arranged at one end of the shell 1, and the air bundling pipe 6 is arranged at the other end of the shell 1. The air-restraining pipe 6 is horizontally arranged in the inner cavity of the shell 1, the spray head 5 is arranged in the inner cavity of the air-restraining pipe 6, the ignition electrode horizontally penetrates through the inner cavity of the shell 1 and extends to the spray head 5, the air duct 3 is arranged in the inner cavity of the shell 1 and is communicated with the spray head 5, and the air inlet 7 is communicated with the inner cavity of the shell 1.

Referring to fig. 5 and 6 in combination, in the present embodiment, a plurality of circular arc-shaped air grooves 61 are arranged at intervals along the axial direction of the outer surface of the bustle pipe 6, adjacent pairs of air grooves 61 are staggered and arranged oppositely on the outer surface of the bustle pipe 6, that is, adjacent pairs of air grooves 61 are arranged at intervals in both the axial direction and the circumferential direction of the bustle pipe 6, the axial installation positions of adjacent pairs of air grooves 61 on the bustle pipe 6 are different, and a pair of air grooves 61 are also arranged oppositely in the circumferential direction of the bustle pipe 6.

Referring to fig. 7, in order to further improve the mixing of the combustion supporting air and the fuel entering the nozzle 5, in some embodiments, the burner further includes a cyclone sheet 4.

Referring to fig. 3 and 7, in particular, the cyclone sheet 4 includes a cylindrical cyclone sheet body 41, a central hole 43 disposed at the center of the cyclone sheet body 41, and a plurality of wind guide grooves 42 disposed at the outer edge of the cyclone sheet body 41, wherein the plurality of wind guide grooves 42 are spaced along the circumferential direction of the cyclone sheet body 41.

When the cyclone sheet is installed, the cyclone sheet is installed on the outer surface of one end of the air duct 3 close to the spray head 5 through the central hole 43, and the outer edge of the air guide groove 42 is attached to the inner wall of the air restricting pipe 6.

The working principle of the novel high-pressure low-flow energy-saving burner in the embodiment is described below with reference to fig. 4 and 8:

fuel (gas) flows to the spray head 5 through the gas guide tube 3, meanwhile, external combustion-supporting air flows to the spray head 5 through the air inlet 7, the inner cavity of the shell 1, the air restricting tube 6 and the cyclone sheet and is mixed with the fuel, and mixed gas is ignited at the spray head 5 through the ignition electrode and is combusted to generate flame.

When the combustion-supporting air flows in the air-restraining pipe 6, the combustion-supporting air firstly enters the inner cavity of the air-restraining pipe 6, and in the process of flowing of the combustion-supporting air in the inner cavity of the air-restraining pipe 6, because a plurality of arc-shaped air grooves are formed in the outer surface of the air-restraining pipe 6 at intervals, the combustion-supporting air in the inner cavity of the air-restraining pipe 6 can flow outwards from the air grooves, and in the process of flowing forwards along the inner cavity of the shell 1, the combustion-supporting air flowing outwards enters the next adjacent air groove on the air-restraining pipe 6 and enters the inner cavity of the air-restraining pipe 6 through the air grooves, and the circulation is performed, so that the combustion-supporting air flows forwards on the outer surface of the air-restraining pipe 6 in a rotating manner, the combustion-supporting air entering the nozzle 5 can be fully mixed with the fuel in the rotating manner, the fuel is completely combusted, and the flame can be lengthened during combustion; in addition, combustion-supporting air entering the spray head 5 is dispersed by the cyclone pieces and is fully mixed with fuel, and the cyclone grooves arranged at the inclined angles on the cyclone pieces increase the rotating speed of the combustion-supporting air, so that the flame spraying distance is further increased.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalent technologies, the present invention is also intended to include such modifications and variations.
