[0029] Please refer to Figures 1-6 , the present invention provides a technical solution: a filter for a fresh air duct that is convenient for disassembly and cleaning, including a filter outer box 1. The filter outer box 1 penetrates the outer surface of the wall, and a block protrusion is provided on the outer surface of the filter outer box 1, and the block protrusion of the filter outer box 1 is attached to the inner surface of the wall. A partition net 2 is fixedly installed on one side of the filter outer box 1, and movable ears 3 are evenly fixedly installed on the side of the filter outer box 1 close to the partition net 2. A rotating buckle 4 is rotatably installed on the outer surface of the movable ear 3. A movable block 5 is rotatably installed inside the rotating buckle 4, and the movable block 5 is located between the rotating buckle 4 and the movable ear 3. A screw 6 is fixedly installed on the side of the movable block 5 away from the partition net 2. A sliding mechanism is provided on the outer surface of the filter outer box 1 to fix the filter outer box 1 through the sliding mechanism. The sliding mechanism includes: a sliding buckle 7. A block protrusion is provided on the side surface of the sliding buckle 7. A groove is provided on the side surface of the filter outer box 1, and the groove on the side surface of the filter outer box 1 is attached to the block protrusion of the sliding buckle 7. A sliding socket 8 is rotatably installed inside the sliding buckle 7, and a through hole is provided through the inside of the sliding socket 8, and the through hole inside the sliding socket 8 is penetrated by the screw 6. A nut 9 is threadedly installed at one end of the screw 6 away from the movable block 5. The outer surface of the movable block 5 is attached to the outer surface of the wall, the outer surface of the sliding buckle 7 is attached to the outer surface of the wall, the outer surface of the sliding socket 8 is attached to the outer surface of the nut 9, and a nut 9 is provided on one side of the nut 9.

[0030] When installing the filtering outer box 1, the worker only needs to fold the rotating buckle 4 from the inside of the house, so that the rotating buckle 4 opens outward with the movable ear 3 as the center. Then, place the filtering outer box 1 into the hole opened in the wall. After that, pull the screw rod 6 to make the movable block 5 rotate and pull back the rotating buckle 4. Snap the sliding buckle 7 onto the side surface of the filtering outer box 1. At the same time, pass the sliding socket 8 through the screw rod 6 and screw it into the nut 9. By screwing in the nut 9, adjust the distance between the rotating buckle 4 and the sliding buckle 7 to clamp the wall with the rotating buckle 4 and the sliding buckle 7, so as to fix the filtering outer box 1. At the same time, the barrier net 2 can effectively prevent birds from entering the inside of the filtering outer box 1, enabling the worker not to install from the outside of the wall and reducing the operation risk.

[0031] Grooves are provided on both sides inside the filtering outer box 1. An inner installation box 10 is slidably installed inside the filtering outer box 1. Block-shaped protrusions are provided on both sides of the inner installation box 10, and the block-shaped protrusions on both sides of the inner installation box 10 are engaged with the grooves on both sides inside the filtering outer box 1. Chutes are provided on both sides of the inner installation box 10.

[0032] By pulling out the inner installation box 10, the filter screen plate 12 can be taken out together with the inner installation box 10. The buckle 11 prevents the filter screen plate 12 from falling. At the same time, the lower brush body 14 at the lower end of the filter screen plate 12 can effectively prevent air from entering the box body 16 from below the filter screen plate 12. At the same time, it can clean part of the bottom of the filtering outer box 1 and lift the filter screen plate 12.

[0033] A push-pull structure is provided inside the inner installation box 10 to facilitate the removal of the filter. The push-pull structure includes: a buckle 11, which is fixedly installed in the chutes on both sides of the inner installation box 10. A filter screen plate 12 is snap-fitted in the chutes of the inner installation box 10. A protrusion is provided at the lower end of the filter screen plate 12. A filter net 13 is inlaid inside the filter screen plate 12. And a lower brush body 14 is fixedly installed on the outer surface of one end of the filter screen plate 12.

[0034] As the inner installation box 10 moves, the ventilation pipe 15 will move and deform accordingly without restricting the movement of the inner installation box 10. After pulling out the inner installation box 10, the filter screen plate 12 can be taken out. Clean and dry the dust on the filter net 13, and then insert the filter screen plate 12 back in sequence. Or the filter screen plate 12 can be pulled out individually for cleaning without affecting the use of the fresh air equipment.

[0035] A ventilation pipe 15 is snap-fitted on the side of the inner installation box 10 away from the wall. A box body 16 is provided on the side of the inner installation box 10 away from the wall. An air inlet 18 is provided through the side surface of the box body 16. One end of the air inlet 18 is connected to the ventilation pipe 15. A fan 17 is provided inside the box body 16. The input port of the fan 17 is connected to the air inlet 18. An air outlet 19 is installed through the side surface of the box body 16. The output port of the fan 17 is connected to the air outlet 19.

[0036] Fix the box body 16 on the roof inside the house. When the fan 17 is started, air will be drawn into the box body 16 through the air inlet 18 and then discharged outwards from the air outlet 19. The separation of the filtering structure from the fan 17 greatly reduces the difficulty in cleaning dust and impurities and greatly improves the efficiency.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
