Description

Technical Field

[0001] This utility model pertains to industrial heaters, specifically relating to a gas-fired fan burner head and a gas-fired fan. Background Technology

[0002] Gas-fired fans, as a highly efficient and convenient heating device, are widely used in homes, offices, and other environments. The burner head is the core component of a gas-fired fan, responsible for mixing gas and air and the combustion process. The structural design of the burner head directly affects performance characteristics such as combustion efficiency, heat output, emissions levels, and safety.

[0003] Chinese Patent CN208967895U discloses a burner cap comprising: a burner cap connecting plate, a guide plate, a guide hood, and a burner cap cover. The diameter of the burner cap connecting plate is more than twice the outer diameter of the burner tube. The burner cap connecting plate is fixedly connected to the burner tube. The guide hood is a circular tube with connecting ends at both ends. One connecting end connects to the burner cap connecting plate, and the other connecting end connects to the guide plate. Guide holes are evenly distributed on the surface of the guide plate. The front end of the guide plate connects to the burner cap cover, which is half an ellipse in shape. The inside of the burner cap cover is hollow, and gas holes are evenly distributed on the wall of the burner cap cover. The rear end of the burner cap cover has an annular burner cap cover connecting end. The burner cap cover, guide plate, guide hood, and burner cap connecting plate have the same outer diameter. Each side of the above components has a corresponding screw connection hole. Screws pass through the upper screw connection holes on the sides of the burner cap cover, guide plate, guide hood, and burner cap connecting plate to connect them as a whole.

[0004] The problem with the existing technology is that the structure of the evenly distributed gas holes on the burner cover causes the flame to be evenly distributed on the surface of the burner cover when the burner head is burning. Some of the flame can be directly sprayed out of the combustion tube. In particular, when the user increases the gas flow rate and the air volume of the blower, the direct flame spray structure poses a safety hazard. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a gas-fired blower burner head that prevents the flame from shooting outwards during ignition, thus avoiding safety hazards.

[0006] A gas-fired blower burner head includes: a burner head mounting plate with an air inlet; a burner head body fixed on the burner head mounting plate, with the air inlet communicating with the inner cavity of the burner head body; and an ignition device fixed on the burner head mounting plate and disposed adjacent to the burner head body. The burner head body is cylindrical, with gas holes arranged in a ring array on the side wall of the burner head body, and the front end of the burner head body is closed.

[0007] As a further improvement to the above technical solution, the gas-fired blower burner head also includes a temperature sensor, which is mounted on the burner head mounting plate.

[0008] As a further improvement to the above technical solution, the temperature sensor and the ignition device are arranged on both sides of the burner head body.

[0009] As a further improvement to the above technical solution, a first groove is provided along the air inlet, and the convex surface of the first groove is aligned with the direction of the burner body.

[0010] This embodiment also provides a gas blower, which includes any of the gas blower burners described above. The beneficial effects of the gas blower using the gas blower burner are as follows: the burner body is arranged adjacent to the ignition device, which can quickly ignite the gas-air mixture and reduce ignition delay; and this design can quickly ignite the gas-air mixture, thereby reducing the accumulation of gas in the combustion chamber and reducing the risk of gas leakage or gas explosion.

[0011] The beneficial effects of this utility model are as follows: Since the burner body is cylindrical, and there are gas holes arranged in a ring on the side wall of the burner body, and the front end of the burner body is closed, the flame will not spray out directly, but will be sprayed laterally onto the inner wall of the heat preservation cover, making it safer to use.

[0020] Reference Figures 1-2 A gas-fired blower burner head includes: a burner head mounting plate 100 with an air inlet; a burner head body 200 fixed to the burner head mounting plate 100, with the air inlet communicating with the inner cavity of the burner head body 200; and an ignition device 300 fixed to the burner head mounting plate 100 and disposed adjacent to the burner head body 200. The burner head body 200 is cylindrical, with gas holes 210 arranged in a ring on the side wall of the burner head body 200, and the front end of the burner head body 200 is closed.

[0021] In this embodiment, the gas-fired blower burner head also includes a temperature sensor, which is disposed on the burner head mounting plate 100.

[0022] In this embodiment, the temperature sensor 400 and the ignition device 300 are disposed on both sides of the burner body 200. This design avoids direct contact between the temperature sensor 400 and the flame, thereby improving the service life of the temperature sensor 400. Furthermore, this arrangement of the temperature sensor 400 body shortens the distance between it and the flame, resulting in high measurement accuracy of the temperature sensor 400.

[0023] In this embodiment, a first groove 220 is provided along the air inlet, and the convex surface of the first groove 220 is aligned with the direction of the burner body 200; this design can reduce the high-speed impact and turbulence of the airflow, thereby reducing noise and making the combustion fan operate more quietly.

[0024] This embodiment also provides a gas-fired blower, which includes any of the gas-fired blower burners described above.
