The implementation principle of the embodiment 1 is as follows:

when the indoor air exchange is needed, only the fan 42 needs to be started, the fan 42 extracts the external air, and when the external air is extracted by the fan 42, the external air firstly passes through gaps formed by the plurality of filter plates 23, and part of large-particle-diameter gravel in the external air collides with the filter plates 23 and falls off.

Further, since the filter sheet 23 is inclined in such a manner that it is high on the outside and low on the inside, the outside air is drawn by the fan 42 in such a path that it first moves downward in the direction of inclination of the filter sheet 23, then moves upward by the suction force of the fan 42 and is finally drawn by the fan 42 to be input into the filter case 1. During the movement of the outside air downwards and upwards, most of the gravel in the outside air falls under the action of the gravity of the outside air. That is, the outer filter device 2 primarily filters the outside air by guiding the movement route when the outside air is extracted.

The air after the preliminary filtering is sent to the manifold 53 by the blower 42 through the connection pipe 51, and in the process, the ozone pipe 52 also sends ozone to the manifold 53 through the connection pipe 51, that is, the air in the manifold 53 is a mixture of outside air and ozone, and the ozone can sterilize the outside air.

The mixed gas in the header pipe 53 is supplied into the filter tube 55 through the branch pipe 54 and ejected through the gas ejection holes 6 of the filter tube 55, thereby forming small bubbles. Due to the special configuration of the gas injection holes 6, the small bubbles ejected from each filter tube 55 can collide, the small bubbles ejected from the adjacent filter tubes 55 can also collide, and the small bubbles colliding with each other are further broken and refined in the filtrate. The refined bubbles can fully contact with the filtrate in the filter box 1 in the process of gradually floating upwards, and dust in the bubbles is adsorbed by the filtrate.

The small bubbles primarily adsorbed by the filtrate float up to the filter layer 8, and when the small bubbles pass through the filter material 82, the dust in the small bubbles can be further filtered by the filter material 82, and the filter material 82 can further subdivide the small bubbles into small bubbles with smaller radius, and the small bubbles with smaller radius can further contact with the filtrate in the rising process, so that the fine dust which is not filtered by the filter material 82 in the small bubbles is adsorbed by the filtrate. And the air after degerming and filtering is output to the indoor for ventilation through the air outlet pipe 11.

When the blower 42 needs to be overhauled or the dust and sand in the installation box 21 needs to be cleaned, only the pressing plate 38 needs to be pushed, the pressing plate 38 drives the locking sheet 34 to rotate, and the locking sheet 34 drives the self-locking sheet 37 to rotate and push the filter plate 23, so that the filter plate 23 is pushed to be pulled out of the installation groove 33. At the same time, the locking piece 34 also drives the locking block 35 out of the locking groove 24, so as to reduce the possibility that the locking block 35 blocks the filter plate 23.
