A sliding groove 18 is provided at the bottom end of the filter box 1, a connecting block 21 is slidably connected inside the sliding groove 18, a wind blocking plate 17 is fixedly connected to the upper end of the connecting block 21, a sliding column 22 is fixedly connected to the bottom end of the connecting block 21, and the sliding column 22 is slidably connected inside the groove of the rotating shaft 19. By making the wind blocking plate 17 perform reciprocating linear motion and continuously changing the position of the wind blocking plate 17, the gas flow direction is changed, so that the gas uniformly passes through each part of the filter screen 15 and the activated carbon adsorption plate 14, thereby realizing the full utilization of the filtering and adsorption capabilities of the filter screen 15 and the activated carbon adsorption plate 14 and improving the filtering and purification efficiency.

[0025] As Figures 1-5 shown, two symmetrically distributed mounting brackets 11 are fixedly connected to the side end of the drive box 10, a drive motor 12 is fixedly connected between the two mounting brackets 11, and the output end of the drive motor 12 is fixedly connected to the rotating shaft 19 to drive the rotation of the rotating shaft 19 through the drive motor 12.

[0026] As Figures 1-5 shown, exhaust fans 16 are fixedly installed inside both air inlet boxes 9 to extract external air.

[0027] As Figures 1-5 shown, sliding frames 13 are fixedly installed on both sides of the filter box 1 corresponding to the activated carbon adsorption plate 14 and the filter screen 15. Sliding blocks 20 are fixedly connected to both sides of the filter screen 15 and the activated carbon adsorption plate 14, and the sliding blocks 20 are slidably connected inside the sliding frames 13. The sliding frames 13 cooperate with the sliding blocks 20 to facilitate the installation of the filter screen 15 and the activated carbon adsorption plate 14.

[0028] As Figures 1-5 shown, an air quality detector 5 is fixedly installed inside the air outlet box 4. The air quality detector 5 can detect the impurity content of the discharged gas and give a reading.

[0029] As Figures 1-5 shown, L-shaped mounting brackets 6 are fixedly connected to the four corners at the rear end of the filter box 1, and mounting holes 7 are reserved at the vertical ends of the L-shaped mounting brackets 6 to facilitate the fixed installation of the device.

[0030] As Figures 1-5As shown in the figure, a door 2 is provided at the front end of the filtering box 1. A plurality of hinge pieces 3 are fixedly connected to the side of the filtering box 1, and the other end of the hinge piece 3 is fixedly connected to the door 2. By providing the door 2, it is convenient to replace the filter net 15 and the activated carbon adsorption plate 14.

[0031] As Figures 1-5 shown in the figure, a handle 8 is fixedly connected to the end face of the door 2, which is convenient for pulling and opening the door 2.

[0032] Working principle: When the device conducts cyclic filtration detection, external gas is inhaled into the filtering box 1 through two mounting frames 11 in two air inlet boxes 9. Large particles of impurities in the gas will be intercepted at the filter net 15, and fine particles are adsorbed by the filter net 15 after passing through multiple activated carbon adsorption plates 14, and then discharged through the air outlet box 4. An air quality detector 5 is provided in the air outlet box 4. The air quality detector 5 can detect the impurity content of the discharged gas and give a reading, which is convenient for the user to replace the activated carbon adsorption plate 14 and the filter net 15 inside the filtering box 1 in time. When the gas enters, it will be blocked by the air blocking plate 17. Since the connecting block 21 is limited by the sliding guide of the sliding groove 18, when the driving motor 12 drives the rotating shaft 19 to rotate, one of the spiral grooves on the rotating shaft 19 can be used to squeeze the sliding column 22 to move. Since the edge of this spiral groove is connected to another spiral groove with the opposite spiral direction through a transition curve, the sliding column 22 can slide in the opposite direction when it slides to the edge of the rotating shaft 19. Cooperating with the connecting block 21, the air blocking plate 17 can be driven to perform a reciprocating linear motion, changing the position of the air blocking plate 17, thereby changing the gas flow direction, so that the gas uniformly passes through each part of the filter net 15 and the activated carbon adsorption plate 14, so as to fully utilize the filtering and adsorption capabilities of the filter net 15 and the activated carbon adsorption plate 14 and improve the filtration and purification efficiency.

[0033] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
