[0012] Furthermore, a mounting groove is provided on the right side of the exhaust box, a plurality of rotating shafts are fixedly installed in the mounting groove, and a second adjusting plate is rotatably sleeved on the outer walls of the plurality of rotating shafts.
[0013] The utility model has the following beneficial effects:
[0014] (1) The utility model is provided with a cleaning mechanism. When the device needs to be used to exhaust air to the outside, the motor can be driven to drive the motor to rotate the rotating shaft 1, which in turn drives the fan blade assembly thereon to rotate. The waste air can be discharged from the conveying pipe through the rotation of the fan blade assembly. When the rotating shaft 1 rotates, the rotating shaft 1 also drives the fixed disk thereon to rotate. The fixed disk drives the rotating shaft 2 and the cleaning assembly on the rotating shaft 2 to rotate. The dust on the filter plate can be scraped off through the rotation of the cleaning assembly to prevent dust accumulation and clogging of the filter plate, resulting in poor exhaust effect.
[0015] The utility model provides a configuration mechanism, and when exhausting air to the outside through the conveying pipe, the wind will pass through the anti-backflow cover. The exhaust port of the anti-backflow cover is designed to be inclined downward, so that the discharged wind flows obliquely downward toward the ground, reducing the possibility of external rain or foreign matter entering. At the same time, the multiple groups of adjustment plates at the exhaust port can prevent wind from flowing back. During daily use, when it is necessary to inspect the body in the exhaust box, the handle can be pulled upward to make the handle drive the cabinet door to rotate, thereby opening the exhaust box, which is convenient for staff to inspect and repair it. When the body in the exhaust box is in use, heat will be generated, and the angle of the multiple groups of adjustment plates can be adjusted to enable the body in the exhaust box to dissipate heat better.
[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
