[0002] With the development of society and the continuous improvement of people's living standards, most existing buses are equipped with air-conditioning fresh air structures. For example, a large-volume bus air-conditioning fresh air structure with variable fresh air ratio disclosed in Chinese Patent Application No. CN202220555255.4, the specific content of which is as follows: It includes a box body, and a fresh air pipe is connected to the bottom of the box body. By setting the fresh air pipe, it is convenient for external fresh air to enter the box body. An installation cover is fixedly connected to the front of the fresh air pipe, and a net plate is movably connected to the inner wall of the installation cover. By setting the net plate, it is convenient to prevent sundries from entering the fresh air pipe. Connecting bolts are respectively arranged through the left and right sides of the installation cover. Through the cooperation of the installation cover and the connecting bolts, it is convenient to disassemble and clean the net plate. It has the following technical problems:

[0003] External fresh air is transported to the inside of the box body through the fresh air pipe. Dust and impurities outside the fresh air pipe are easily adsorbed on the net plate. Therefore, the net plate often needs to be disassembled and cleaned. Fixed by bolts, it is necessary to rotate the bolts multiple times, which is rather cumbersome. Moreover, after the bolts are rotated for a long time, they are prone to slipping threads and cannot be used. It is also necessary to equip the same-sized screws to fix the net plate. Therefore, the operation of disassembling and cleaning the net plate is rather cumbersome. Content of the Utility Model

A plurality of bristles 311 are fixedly installed on the inner wall of the U-shaped plate 310. At the lower end of the U-shaped plate 310, a lead screw nut 320 for cooperating with the reciprocating lead screw 400 to control the left and right movement of the U-shaped plate 310 is fixedly installed. When the mesh plate 110 falls into the inner cavity of the water tank 500, the mesh plate 110 is located in the middle groove of the U-shaped plate 310, so that both ends of the mesh plate 110 are cleaned by the bristles 311.

[0045] At the lower end of the cleaning assembly 300, a reciprocating lead screw 400 for controlling the left and right movement of the cleaning assembly 300 is installed. At one end of the reciprocating lead screw 400, a motor 410 for controlling the rotation of the reciprocating lead screw 400 is installed.

[0046] When dust and impurities adhere to the surface of the mesh plate 110, the connecting rod three 140 is pulled out from the middle of the elastic bushing 230, so that the connecting rod one 121, the connecting rod two 130, and the connecting rod three 140 are in a vertical state. The outer frame 120 is pressed downward, so that the outer frame 120 drives the mesh plate 110 to move into the inner cavity of the water tank 500. When the mesh plate 110 moves to the middle groove of the U-shaped plate 310, an external water pipe is connected to the water inlet pipe 510, so that water flushes the mesh plate 110 through the water spraying pipe 540 and the spray nozzles 541, and the motor 410 is started synchronously, so that the reciprocating lead screw 400 rotates, driving the lead screw nut 320 to move left and right on the rod body of the reciprocating lead screw 400, so that the U-shaped plate 310 drives the bristles 311 to repeatedly clean the mesh plate 110 to clean the mesh plate 110. After the mesh plate 110 is cleaned, the connecting rod three 140 is lifted upward, so that the outer frame 120 drives the mesh plate 110 to move to the middle of the box body 210, and the connecting rod three 140 is inserted into the middle of the elastic bushing 230 to lock the position of the mesh plate 110.
