[0035] Working principle: When in use, the outer frame 1 is installed on the building through the mounting holes and bolts on the mounting plate 4, and the inner frame 7 is inserted into the outer frame 1. During use, the photovoltaic panel 5 and the battery 11 can absorb and store solar energy, and the solar drive device is operated to achieve energy saving. The fan 10 is used to exchange air inside and outside. When the air passes through the inner frame 7, the impurities in the air are filtered through the air filter 8, and the air is sterilized and disinfected by the ultraviolet lamp 9 to avoid bringing impurities such as external bacteria and dust into the room. When disassembling, turn the rotary The button drives the screw 16 to rotate, and drives the gear 15 to rotate through the fixing tube 6, so that the rack is separated from the slot and the cover body 2 is loosened. Then the inner frame 7 can be pulled out from the outer frame 1 through the handle, so that the device can be quickly removed from the building for maintenance and cleaning. Then the inner frame 7 is inserted into the outer frame 1, the fixing plate is aligned with the slide groove, and the inner frame 7 is smoothly inserted into the outer frame 1 through the ball bearing, and the cover body 2 is sleeved on the outside of the mounting plate 4.
