The sliding shutter 142 is disposed in the first chute 1411 and the second chute 1461 through the guide posts 1421 at both ends. The sliding shutter 142 can move linearly along the rail to close or open the air inlet 122. When the slide fence 142 is moved away from the intake port 122 to the first baffle position, the intake port 122 is opened and air can enter the intake seal chamber 120 through the intake port 122. When the sliding baffle 142 is moved to the second baffle position, the sliding baffle 142 is engaged with the first side wall 123 under the guidance of the air intake opening end of the first chute 1411 and the second chute 1461. The port 122 is closed and air cannot enter the inspiratory sealed chamber 120 through the air inlet 122.

The switching motor 133 drives the sliding shutter 142 to move until the sliding shutter 142 is in the second shutter position, closing the air inlet 122. The air in the outdoor space enters the open side of the switching valve 130 through the outdoor side passage 160, and then flows to the suction sealing chamber 120 due to the suction of the suction port 171 of the suction motor 170. At this time, since the air inlet 122 is closed, the air can only enter the suction motor 170 in the air suction sealing chamber 120 through the filter screen 121, so that the filter screen 121 is in an operating state, and the particles harmful to the human body in the air are removed. Filtered fresh air from The air outlet 172 of the air suction motor 170 enters the closed side, and then enters the indoor space through the indoor side passage 150, thereby ensuring the quality of the air delivered to the indoor space, and making the indoor environment more comfortable.
