Description

Technical Field

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

[0002] Gas-fired fans, as a highly efficient and convenient heating device, are widely used in homes, offices, and other environments. Their core component—the burner—is responsible for mixing and burning the gas and air, and its performance directly affects the fan's safety, thermal efficiency, and emissions levels. Currently, due to limitations in the burner structure, insufficient mixing of air and gas occurs in gas-fired fans, resulting in incomplete combustion. Utility Model Content

[0003] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a gas blower with an annular burner head, which can make the gas and air fully mixed, thereby making the combustion more complete.

[0004] A gas-fired blower with an annular burner head includes: a housing with an air inlet at one end and an air outlet at the other end; an inner cover disposed within the inner cavity of the housing, with an air inlet at one end and an air outlet at the other end, the air inlet corresponding to the air inlet of the housing and the 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; an annular burner head disposed inside the inner cover; an ignition device disposed on the annular burner head; an air intake assembly connected to the annular burner head via an air intake pipe; and a control device controlling the operating status of the ignition device and the blower assembly.

[0005] As a further improvement to the above technical solution, the annular burner head has several gas holes evenly provided on the front side wall, the annular burner head has a break, and the annular burner head is made by bending a round tube closed at one end.

[0006] 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.

[0007] As a further improvement to the above technical solution, the center of the annular furnace head and the center of the blower body are set on the same straight line.

[0008] As a further improvement to the above technical solution, the gas blower with an annular burner head also includes a temperature sensor, which is disposed on the annular burner head.

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

[0010] As a further improvement to the above technical solution, the inner cover is fixed inside the cavity of the outer shell by an inner cover bracket.

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

[0012] The beneficial effects of this utility model are as follows: A gas blower with an annular burner head includes: a shell; a blower assembly; an inner cover; an annular burner head; an ignition device disposed on the annular burner head; an air intake assembly connected to the annular burner head via an air intake pipe; and a control device that controls the working state of the ignition device and its blower assembly. Because the gas blower with the annular burner head adopts the structure of the annular burner head, air can enter from both the inner and outer sides of the annular burner head, increasing the contact area between the gas and air, allowing for better mixing of the gas and air, thereby promoting complete combustion of the gas, improving thermal efficiency, and reducing gas waste.

[0022] Reference Figures 1-3 A gas-fired blower with an annular burner head includes: a housing 100, with an air inlet 110 at one end and an air outlet 120 at the other end; an inner cover 200 disposed within the inner cavity of the housing 100, with an inner cover air inlet 210 at one end and an inner cover air outlet 220 at the other end, the inner cover air inlet 210 corresponding to the housing air inlet 110 and the inner cover air outlet 220 corresponding to the housing air outlet 120; a blower assembly disposed between the housing air inlet 110 and the inner cover air inlet 210; an annular burner head 400 disposed inside the inner cover 200; an ignition device 500 disposed on the annular burner head 400; an air intake assembly connected to the annular burner head 400 via an air intake pipe 610; and a control device 700 controlling the operating status of the ignition device 500 and its blower assembly.

[0023] In this embodiment, the annular burner head 400 has a plurality of gas holes 410 evenly distributed on its front sidewall. The annular burner head 400 has a break in its shape and is formed by bending a circular tube closed at one end. Because the gas fan with the annular burner head adopts the structure of the annular burner head 400, air can enter from both the inside and outside of the annular burner head 400, increasing the contact area between the gas and air. This allows for better mixing of the gas and air, thereby promoting complete combustion of the gas, improving thermal efficiency, and reducing gas waste.

[0024] In this embodiment, the annular burner head 400 is uniformly provided with a plurality of gas holes 410.

[0025] In this embodiment, the fan assembly includes a drive motor 310 and a fan body 320. The fan body 320 is connected to the drive motor 310, and the drive motor 310 is connected to the control device 700. The control device 700 controls the working state of the drive motor 310.

[0026] In this embodiment, the center of the annular burner head 400 and the center of the fan body 320 are aligned on the same straight line; this design allows for a more uniform airflow into the inner and outer sides of the annular burner head 400, thereby resulting in a more uniform mixing of gas and air.

[0027] In this embodiment, the gas blower with an annular burner head also includes a temperature sensor 800, which is installed on the annular burner head 400. This design can detect the temperature of the combustion zone of the burner head in real time, ensuring that the combustion process is within the optimal temperature range. When the temperature of the annular burner head 400 exceeds the safety threshold, the temperature sensor will trigger a protection mechanism, thereby improving safety performance.

[0028] In this embodiment, the air intake assembly is provided with an air intake valve 620.

[0029] In this embodiment, the inner cover 200 is fixed inside the cavity of the outer shell 100 by the inner cover bracket 230; this design allows the inner cover 200 to be more securely fixed inside the cavity of the outer shell 100.

[0030] As a further improvement to the above technical solution, the outer casing 100 is provided with a handle 130; the handle 130 facilitates the user to move the gas blower with the annular burner head.
