[0034] like Figure 3 , Figure 4 and Figure 6As shown, the adjustment mechanism 4 includes a first partition 401, a second partition 402, a rotating rod 403, a first insert rod 404, a second insert rod 405, an adjustment hole 406, an adjustment plate 407, a servo motor 408, and a servo driver 409. The first partition 401 is welded to the inner wall of the housing 1. The second partition 402 is disposed on one side of the first partition 401 and welded to the inner wall of the housing 1. The rotating rod 403 is disposed between the first partition 401 and the second partition 402. The first insert rod 404 and the second insert rod 405 are respectively welded to the adjustment hole 406, the adjustment plate 407, the adjustment plate 408, and the adjustment mechanism 409. Adjustment holes 406 are formed on the side walls of the rotating rod 403 on opposite sides of the first partition 401 and the second partition 402. Adjustment plates 407 are bolted to the outer wall of the rotating rod 403. A servo motor 408 is bolted to the side wall of the first partition 401 facing away from the rotating rod 403 and is coaxially arranged with the first insertion rod 404. A servo driver 409 is bolted to the outer wall of the housing 1.

The first insertion rod 404... 04. The central axes of the second insert rod 405 and the rotating rod 403 coincide with the central axes of the first partition 401 and the second partition 402. The number of adjusting holes 406 and adjusting plates 407 are several and distributed circumferentially along the central axis of the rotating rod 403. The first insert rod 404 and the second insert rod 405 respectively pass through the first partition 401 and the second partition 402 and are rotatably connected to them. The servo driver 409 is electrically connected to the servo motor 408, and the servo motor 408 can drive... The first insertion rod 404 rotates. During use, the air intake pipe 2 is connected to the external air source, and the exhaust pipe 3 is connected to the burner. When the air enters the housing 1 through the air intake pipe 2, if the air volume needs to be adjusted, the user can drive the servo motor 408 through the servo driver 409. The servo motor 408 drives the first insertion rod 404, the rotating rod 403, the second insertion rod 405, and the adjusting plate 407 to rotate. At this time, the area of ​​the adjusting plate 407 blocking the adjusting hole 406 will change. When the required air volume is reached, the servo motor 408 can be turned off.

There are two of each of the first arc-shaped plate 501, the second arc-shaped plate 502, the first connecting rod 503, and the second connecting rod 504, and they are symmetrically arranged about the central axis of the housing 1. In use, the base plate 505 works in conjunction with the first arc-shaped plate 501, the second arc-shaped plate 502, the first connecting rod 503, and the second connecting rod 504 to provide support for the housing 1 and improve the stability of the housing 1.

[0036] like Figure 1 As shown, four casters 6 are bolted to the bottom of the base plate 505 and are located at the four corners of the base plate 505. When in use, the device can be moved easily by the casters 6, which improves convenience.

[0037] like Figure 1 As shown, a first round rod 11 and a second round rod 12 are respectively bolted to the side walls of the first connecting rod 503 and the second connecting rod 504. A crossbar 13 is welded to one end of the first round rod 11 and the second round rod 12. When in use, the device can be easily moved by holding the crossbar 13.

[0038] like Figure 3 and Figure 4 As shown, an air volume sensor 7 is attached to the inner wall of the housing 1, and a display screen 8 is attached to the outer wall of the housing 1.

[0040] like Figure 3 As shown, an arc-shaped air guide 10 is provided between the inner wall of the housing 1 facing the second partition 402 and the inner wall perpendicular to the second partition 402. When in use, the arc-shaped air guide 10 can guide the air discharged through the adjustment hole 406 to the exhaust pipe 3, thereby increasing the exhaust speed.

[0041] Specifically, when using the airflow regulator for this burner: push the device to the designated position using the crossbar 13 and the caster wheel 6, then connect the servo motor 408 and servo driver 409 to the external power supply, connect the air intake pipe 2 to the external air source, and connect the exhaust pipe 3 to the burner. When air enters the housing 1 through the air intake pipe 2, if the airflow needs to be adjusted, the user can drive the servo motor 408 through the servo driver 409. The servo motor 408 drives the first insertion rod 404, the rotating rod 403, the second insertion rod 405, and the adjusting plate 407 to rotate. At this time, the distance between the adjusting plate 407 and the adjusting hole 406 will change. The airflow sensor 7 can sense the airflow inside the housing 1 and then transmit the airflow data to the display screen 8, so that the user can observe the airflow in real time and improve the accuracy of adjusting the airflow. When the required airflow is reached, the servo motor 408 can be turned off.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
