Referring to fig. 1, a filling space 13 is provided above the functional cavity 15 in the wooden door 11, and the filling space 13 is filled with a sound insulation material.

Referring to fig. 1 and 2, the length of the air blowing openings 22 in the vertical direction is the same as that of the wooden door 11, at least three air blowing openings 22 are arranged on one side, and the length of the communication part of the ventilation channel 21 and the sealed cavity 14 in the vertical direction is the same as that of the sealed cavity 14 in the vertical direction.

In the initial state, the opposite side of the elastic sealing plate 31 is abutted against the air and can not pass through, the wooden door 11 is in the open state, the space between the walls 10 is not closed, the sealing sliding block 32 is positioned at the position above the elastic sealing plate 31 in the middle of the collecting cavity 30, and the return spring 33 is not compressed.

When the wood door is in work, when a user closes the wood door 11, the wood door 11 moves towards the outside of the sealed cavity 14, so that the sealing strips 20 are respectively driven to move to drive the rotating wheels 40 to rotate, and because the sealing strips 20 are tightly attached to the inner wall of the sealed cavity 14, gas cannot pass through, the space of the sealed cavity 14 is enlarged, the gas pressure is reduced, and external high gas pressure drives the gas to enter the sealed cavity 14 through the gas blowing port 22 via the gas ventilation channel 21, so that the same external atmospheric pressure of the sealed cavity 14 is ensured;

meanwhile, the sealing strip 20 pulls the sealing sliding block 32 upwards through the pull rope 34, so that the return spring 33 is gradually compressed, the space enclosed by the sealing sliding block 32 and the elastic sealing plate 31 is completely closed, when the sealing sliding block 32 moves upwards, the space is expanded, the air pressure of the space is reduced and is lower than the external atmospheric pressure, and as the dust suction part is communicated with the external air, the external air enters the space through the dust suction part to balance the air pressure, when the external air is sucked, the dust in the sliding groove of the guide rail 12 is sucked through the dust suction port 52 and then enters the collection cavity 30 to be collected through the air suction pipe 36, the one-way flow device 37 and the exhaust pipe 35 in sequence;

while the wooden door 11 is moved, the rotary wheel 40 rotates the rotary shaft 43, thereby rotating the driven shaft 44 through a pair of gear pairs, so that the driven shaft 44 drives the rotary drum shaft 46 to rotate through a pair of belt pulleys, thereby driving the rotary drum 45 to rotate, since one end of the slide rod 47 is slidably disposed in the groove of the drum 45, when the drum 45 rotates, the slide rod 47 is caused to slide in the groove, so that the slide rod 47 drives the connecting rod 48 to horizontally reciprocate, and the connecting rod 48 drives the connecting frame 50 to horizontally reciprocate, when the connecting frame 50 starts to move, the scraping block 53 is driven to slide in the sliding groove of the guide rail 12 through the second hinge rod 55 and the first hinge rod 51 in sequence, so that the scraping block 53 sweeps off the dust attached in the sliding groove, the swept-off dust is sucked by the dust suction port 52 and is absorbed through the process, and the aim of cleaning the sliding groove of the guide rail 12 is fulfilled;

when a user opens the wooden door 11, the wooden door 11 slides into the sealed cavity 14, at this time, the space in the sealed cavity 14 is rapidly reduced, due to the action of the sealing strip 20, the gas in the sealing strip 20 is pressed into the ventilation channel 21 and is rapidly discharged through the gas blowing port 22, due to the rapid speed of the gas blown out from the gas blowing port 22, the dust on the surface of the wooden door 11 is blown down to the ground, thereby achieving the purpose of cleaning the surface of the wooden door 11, meanwhile, the pull rope 34 is gradually loosened, so that the sealing sliding block 32 moves downwards under the elastic force of the return spring 33, because the unidirectional flow device 37 can only make the gas pass through in one direction, the air pressure of the space enclosed by the sealing sliding block 32 and the elastic sealing plate 31 is gradually higher than the air pressure below the elastic sealing plate 31, the elastic sealing plate 31 deforms under the air pressure, so that the dust in the space enclosed by the elastic sealing plate 31 and the sealing sliding block 32 enters the bottom of the collecting cavity 30 for collection, when the gas pressure is smaller than the deformed restoring force of the elastic sealing plate 31, the opposite side of the elastic sealing plate 31 is again abutted.
