Description

Technical Field

[0001] The utility model relates to the technical field of fresh air systems, in particular to a cleaning structure for fresh air systems. Background Art

[0002] The fresh air system is an independent air treatment system consisting of an air supply system and an exhaust system. It is divided into two types: ducted fresh air system and ductless fresh air system. The ducted fresh air system is composed of a fresh air fan and duct accessories. The fresh air fan purifies the outdoor air and introduces it into the room, and the indoor air is discharged through the duct. The ductless fresh air system is composed of a fresh air fan, which also purifies the outdoor air and introduces it into the room. In order to prevent mosquitoes or solid debris from the outside from entering the cabinet through the air inlet, an insect net is now installed at the air inlet of the fresh air equipment.

[0003] However, the current fresh air system has some shortcomings. For example, the application number is 202221614509.1, which discloses "a self-cleaning structure for an air inlet for a fresh air system". Since the installation position of the rotating seat and the brush strip is located in front of the insect-proof net, when the brush strip is not in use, the brush strip will affect the outside air passing through the insect-proof net, and the brush strip will be worn out during use. When the brush strip is worn out, the tightness of the contact between the brush strip and the insect-proof net will be weakened, which will affect the cleaning effect of the brush strip on the insect-proof net.

[0014] In the utility model, by arranging a cabinet, an insect-proof net, a rotating frame, a brush plate, a motor, and a toothed plate in a manner that cooperates with each other, the brush plate is in close contact with the insect-proof net under the action of the push spring of the rotating frame. When the motor drives the No. 1 gear to rotate, the rotating No. 1 gear drives the insect-proof net to rotate. At this time, the brush plate can brush the insect-proof net. When the No. 1 gear rotates, the toothed plate is driven to move upward. After the toothed plate rises to a certain height, the No. 1 gear will be disconnected from the toothed plate. At this time, the lifting spring will push the toothed plate downward. When the brush plate finishes cleaning the insect-proof net, the motor drives the No. 1 gear to reverse. At this time, the No. 1 gear drives the toothed plate to descend. The descending toothed plate drives the No. 2 gear of the rotating frame to rotate. At this time, the rotating frame will drive the brush plate to rotate and stand up, so that the brush plate is moved away from the front of the insect-proof net, which will not affect the air circulation.
