[0025] Example

[0026] Reference Figure 1-4 This embodiment of the present invention provides a fresh air system filter structure that is easy to clean, comprising:

[0027] The fresh air assembly 100 includes a housing 101. Mounting parts 102 are fixed to the top of both sides of the housing 101. An air heat exchanger 103 is installed at the center of the inner cavity of the housing 101. Partitions 104 are fixed to both sides of the air heat exchanger 103. The outer side of the partitions 104 is fixed to the inner wall of the housing 101. Filters 105 are installed at the top and bottom of the partitions 104. Cleaning components 200 for cleaning the filters 105 are provided on both sides of the inner cavity of the housing 101. A sliding groove 202 facilitates the movement of a sliding rod 208. A drive motor 203, a gear 204, and a rack 205 facilitate the movement of the sliding rod 208 and the cleaning brush plate 209.

[0028] Among them, the top right side of the chassis 101 is connected to the exhaust air inlet pipe 106, the top left side of the inner wall of the chassis 101 is equipped with an exhaust fan 107, the top left side of the chassis 101 is connected to the exhaust air outlet pipe 108, the bottom right side of the chassis 101 is connected to the fresh air outlet pipe 109, the bottom right side of the inner wall of the chassis 101 is equipped with a fresh air fan 110, and the bottom left side of the chassis 101 is connected to the fresh air inlet pipe 111.

[0029] Specifically, the inner cavity of the mounting part 102 is provided with mounting holes, and the outer side of the filter 105 is fixed to the inner wall of the chassis 101. By providing the mounting part 102 and mounting holes, the chassis 101 can be easily installed.

[0030] Furthermore, the cleaning component 200 includes a housing 201. Sliding grooves 202 are provided at both the front and rear ends of the inner side of the housing 201. A drive motor 203 is installed at the bottom of the inner wall of the housing 201. A gear 204 is fixedly installed at the output end of the drive motor 203. A rack plate 205 meshes with both sides of the gear 204. Through the setting of the cleaning component 200, dust and insects on the filter 105 can be brushed, which facilitates the brushing and cleaning of the filter 105, prevents the filter 105 from becoming clogged, and improves the performance of the fresh air system.

[0031] Preferably, a guide sleeve 206 is fixed to the outer side of the rack plate 205, and a guide rod 207 is movably connected to the inner cavity of the guide sleeve 206. By setting the guide sleeve 206 and the guide rod 207, the rack plate 205 is stabilized when moving, so that the rack plate 205 can run in a straight line.

[0032] It should be noted that a sliding rod 208 is fixed on the inner side of the rack plate 205 and slidably connected to the inner cavity of the sliding groove 202. The inner end of the sliding rod 208 extends through to the outside of the housing 201 and is fixed with a cleaning brush plate 209. By setting the sliding rod 208 and the cleaning brush plate 209, the filter 105 can be easily cleaned by brushing.

[0033] The outer side of the enclosure 201 is fixed to the inner wall of the chassis 101, and the outer end of the guide rod 207 is fixed to the inner wall of the enclosure 201.

[0034] When in use, to exhaust indoor air, the exhaust fan 107 starts to draw air from the cavity of the housing 101. Air is drawn into the cavity of the housing 101 through the exhaust intake pipe 106, filtered through the filter 105, and then exhausted to the outside through the exhaust outlet pipe 108. To add fresh air to the room, air is drawn into the cavity of the housing 101 through the fresh air intake pipe 111, filtered through the filter 105, and treated by the air heat exchanger 103. The fresh air fan 110 then starts to deliver fresh air through the fresh air outlet pipe 110. When the air is discharged into the room, and the filter 105 is cleaned, the drive motor 203 starts and drives the gear 204 to rotate. The rotation of the gear 204 drives the two rack plates 205 to move inward through the meshing of the teeth. The movement of the rack plates 205 causes the guide sleeve 206 to slide on the surface of the guide rod 207. The movement of the rack plates 205 causes the sliding rod 208 to slide in the inner cavity of the sliding groove 202. The movement of the sliding rod 208 causes the cleaning brush plate 209 to move to brush and clean the filter 105, preventing the filter 105 from becoming clogged and improving the performance of the fresh air system.

[0035] In summary, by using the cleaning component 200 in conjunction with the drive motor 203, gear 204, rack plate 205, sliding rod 208, and cleaning brush plate 209, dust and insects on the filter 105 can be brushed away, making it easy to clean the filter 105 and preventing it from becoming clogged. This improves the performance of the fresh air system. By starting the exhaust fan 107, indoor air can be drawn out and discharged to the outside through the exhaust inlet pipe 106 and exhaust outlet pipe 108. By starting the fresh air unit 110, outdoor air can be discharged into the room through the fresh air outlet pipe 109 and fresh air inlet pipe 111, passing through the filter 105 and air heat exchanger 103.
