[0024] More specifically, the device is installed on the ceiling, and one end of the air inlet duct 1 extends to the outside. When the filter 7 needs to be replaced, it is only necessary to slide the two adjusting plates 16 toward each other. The sliding of the adjusting plates 16 drives the guide rod 15 to slide in the inner cavity of the guide groove 13. The sliding of the guide rod 15 drives the sliding block 9 to slide, which on the one hand squeezes the return spring 10 and on the other hand returns the positioning rod 11. Then, the top baffle 6 is pulled upward to pull the filter 7 out of the inner cavity of the air inlet duct 1 and replace it with a new one. It is simple and convenient and does not require any tools.

At this time, open the corresponding solenoid valve 21, and the wind can be introduced into the inner cavity of the connecting pipe 20 and discharged for ventilation. When the filter 7 needs to be replaced, just slide the two adjusting plates 16 toward each other. The sliding drives the guide rod 15 to slide in the inner cavity of the guide groove 13, and the sliding of the guide rod 15 drives the sliding block 9 to slide, which on the one hand squeezes the return spring 10, and on the other hand moves the positioning rod 11 out of the inner cavity of the positioning groove 12. At this time, the limiting state of the top baffle 6 and the longitudinal slot 3 disappears, and then the top baffle 6 is pulled upward to pull the filter 7 out of the inner cavity of the air inlet duct 1, and then replace the new filter 7, and reinsert the filter 7 into the inner cavity of the air inlet duct 1 until the bottom of the filter 7 is engaged with the inner cavity of the U-shaped seat 5, and then loosen the adjusting piece 16.
