[0002] The air-conditioning main unit on some buses is generally fixed on the top of the vehicle, and the air inlet and outlet masks are installed in the vehicle to continuously extract and circulate the air in the vehicle. Patent No. 202311643435.3 discloses a new energy vehicle air-conditioning main unit, and the air inlet and outlet masks of the air-conditioning main unit are provided with a partition plate to divide the air inlet and outlet masks into an air inlet area and an air outlet area, but the air outlets in the air outlet area need to be manually switched on and off and the distribution range of the air outlets is limited to the air outlet area. The range of the air outlet area is at one end of the air inlet and outlet masks, resulting in an insufficient blowing range. The air inlet is located at the other end of the air inlet and outlet masks and is installed together with the air-conditioning control panel. The air inlet is distributed too widely, resulting in a part of the cold air discharged from the air outlet entering the air inlet, which may cause the hot air in the vehicle to enter the air-conditioning main unit and slow down the heat exchange.
