Description

Technical Field

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

[0002] Gas-fired fans, as efficient and convenient heating devices, are widely used in homes, offices, and other environments. Their core component—the burner head—is responsible for mixing and burning gas and air; its performance directly affects the fan's safety, thermal efficiency, and emissions. Chinese patent CN208967895U discloses a burner head cover, comprising: a burner head connecting plate, a guide plate, a guide shroud, and a burner head cover. The diameter of the burner head connecting plate is more than twice the outer diameter of the burner head tube. The burner head connecting plate is fixedly connected to the burner head tube. The guide shroud is a circular tube with connecting ends at both ends. One connecting end connects to the burner head 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 head cover, which is half an ellipse in shape. The inside of the flame cap is a cavity, and the flame cap wall is evenly distributed with gas holes. The rear end of the flame cap is provided with an annular flame cap connection end. The flame cap, guide plate, guide shroud and flame cap connection plate have the same outer diameter. Each side of the above components is provided with a screw connection hole corresponding to the hole position. The screw passes through the upper screw connection hole on the side of the flame cap, guide plate, guide shroud and flame cap connection plate to connect them into one piece.

[0003] 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

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a gas fan that prevents the flame from shooting outwards during ignition, thus avoiding safety hazards.

[0005] A gas-fired blower includes: a housing with an air inlet at one end and an air outlet at the other end; an inner cover with an inner cover support frame on its outer wall, the inner cover being fixed inside the housing by the inner cover support frame, one end of the inner cover being an inner cover air inlet and the other end being an inner cover air outlet, the inner cover air inlet corresponding to the air inlet of the housing and the inner cover air outlet corresponding to the air outlet of the housing; a blower assembly disposed between the air inlet of the housing and the air inlet of the inner cover; a burner assembly disposed inside the inner cover and near the air inlet of the inner cover; the burner assembly includes a burner body, the burner body being cylindrical, the side wall of the burner body having a circular array of gas holes, and the front end of the burner body being closed; an ignition device disposed adjacent to the burner body; an air intake assembly communicating with the burner body through an air intake pipe; and a control device controlling the opening and closing of the ignition device and the blower assembly.

[0006] As a further improvement to the above technical solution, the burner assembly also includes a burner mounting plate, and the burner body and the ignition device are arranged adjacent to each other on the burner mounting plate.

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

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

[0009] As a further improvement to the above technical solution, the air intake assembly includes an air intake valve.

[0010] As a further improvement to the above technical solution, the fan assembly includes a drive motor and a fan body, the fan body is connected to the drive motor, the drive motor is connected to the control device, and the control device controls the working state of the drive motor.

[0011] As a further improvement to the above technical solution, a handle is provided on the outer wall of the outer casing.

[0012] The beneficial effects of this utility model are as follows: A gas blower includes: a shell; a blower assembly; an inner cover; the burner assembly includes a burner body; an ignition device disposed adjacent to the burner body; an air intake assembly connected to the burner body via an air intake pipe; and a control device that controls the working state of the ignition device and its blower assembly. Because the burner body and the ignition device are disposed adjacent to each other, the flame can quickly cover the entire combustion area after ignition, helping to rapidly form a stable flame and thus avoiding flame ejection, incomplete combustion, or flameout. The adjacent arrangement of the burner body and the ignition device allows for rapid ignition of the gas-air mixture, reducing ignition delay. Furthermore, this design allows for rapid ignition of the gas-air mixture, reducing gas accumulation in the combustion chamber and minimizing the risk of gas leakage or explosion.
