[0025] A motor 505 is fixedly mounted on the outer wall of one end of the cover 501, and the rotating shaft of the motor 505 is coaxially fixed to one end of one of the two-way screw rods 504. The outer wall of the other end of the cover 501 is rotatably connected to two pulleys 506. The two pulleys 506 are sleeved with the same belt 507, and the two pulleys 506 are coaxially fixed to one end of the two two-way screw rods 504 respectively.

[0026] When the burner body 1 fails, as long as a bidirectional screw rod 504 is driven to rotate by starting the motor 505, the bidirectional screw rod 504 will drive a pulley 506 connected to it to rotate, and the pulley 506 will drive another pulley 506 to rotate through the belt 507, and then the other bidirectional screw rod 504 will also rotate synchronously, so as to ensure that the movement process of the cover 501 is stable enough, and the two moving blocks 503 restricted by the cover 501 will be driven by the bidirectional screw rod 504 to approach each other, and then the cover 501 will also be driven away from the burner body 1 by the two connecting rods 502, and the internal components of the burner body 1 will be exposed.

[0027] like Figure 1 and Figure 2As shown, a fan 2 is fixedly mounted on the outer wall of one side of the burner body 1, and the air outlet of the fan 2 is connected to the burner body 1, a bottom plate 3 is fixedly mounted at the bottom of the fan 2, and a filter assembly 6 is mounted on the top of the bottom plate 3.

[0028] The airflow generated by the operation of the fan 2 flows toward the air outlet, mixes with the external fuel gas and enters the burner body 1 for combustion. The external air also flows toward the air inlet of the fan 2.

[0029] like Figure 2 and Figure 4 As shown, the filter assembly 6 includes a mounting ring 601 fixedly connected to the top outer wall of the base plate 3, the circumferential inner wall of the mounting ring 601 is rotatably connected to a filter plate 602, the filter plate 602 covers the outside of the air inlet of the fan 2, the circumferential outer wall of the filter plate 602 is fixedly sleeved with a gear ring 603, a motor 2 604 is fixedly installed on the outer wall of one end of the mounting ring 601, a gear 605 is coaxially fixed to the rotating shaft of the motor 2 604, and the gear 605 is meshed with the gear ring 603.

[0034] The utility model provides a gas burner which is easy to maintain, and the specific working principle is as follows:

[0035] When the device is working, the airflow generated by the operation of the fan 2 flows toward the air outlet, and is mixed with the external gas to enter the burner body 1 for combustion.
