[0003] With the development of science and technology, today's fresh air ventilation equipment can be equipped with a total heat exchanger to recover heat from the exhausted air. Therefore, heat recovery rotary fresh air ventilation equipment needs to be installed in the factory. Most heat recovery rotary fresh air ventilation equipment does not have a complete wind field filtering mechanism, which makes it easy for small external impurities to pass through the ventilation duct for heat recovery inside the rotary fresh air ventilation equipment, and then be adsorbed in the total heat exchanger, affecting the normal operation of the total heat exchanger and resulting in poor use effect.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, by providing an air filter assembly, when the staff installs the filter before the fresh air ventilation equipment is installed to the indoor top, the staff needs to push the push rod horizontally, and the push rod drives the sealing slot plate to displace on the inner wall of the stroke plate, and the sealing slot plate is separated from the notch of the filter slot, and then one side of the filter frame with the filter installed is aligned with its notch. After alignment, the filter frame can be pushed into the filter slot. At this time, one side of the filter frame squeezes the reset plate, and the reset plate squeezes one end of the first spring at the same time to form a compressed state. At this time, the reset plate is compressed into the inside of the spring slot due to the squeezing, and the staff pushes the push rod again, and the push rod drives the sealing slot plate to reset, so that the sealing slot plate and the notch of the filter slot overlap, thereby preventing the filter frame from being rebounded. When it is necessary to replace the filter with a new one, just push the push rod again, and the push rod drives the sealing plate to move, so that the sealing plate is separated from the notch of the filter slot, and the sealing plate no longer squeezes the filter frame. At this time, the elastic force generated by the first spring in the compressed state drives the reset plate to move, so that it pops out from the reset plate from the inside of the spring slot. When the reset plate moves, it also drives the filter frame to move, so that the other side of the filter frame pops out from the notch of the filter slot. The staff can easily take out the filter frame with the filter installed for replacement. Through this design, it is effectively avoided that the fine impurities from the outside are recovered through the ventilation duct to the inside of the rotary fresh air ventilation equipment, and prevented from being adsorbed on the full heat exchanger, which greatly improves the heat recovery efficiency of the full heat exchanger and has a good use effect.

[0016] 2. In the present invention, a buckle assembly is provided. Before the sealing slot plate is pushed by the push rod, it is necessary to pull the pull rod first. The pull rod drives the compression spring plate to move. While the compression spring plate moves, one end of the second spring is squeezed. The second spring forms a compressed state. The compression spring plate also drives the buckle pin to move, so that the buckle pin moves out from the buckle hole provided on one side of the connecting frame, thereby releasing the fixation. The sealing slot plate can be pushed by the push rod. Through this design, the sealing slot plate in the air filter assembly is effectively fixed, and the displacement of the sealing slot plate due to external factors is avoided, which greatly improves the stability of the air filter assembly and has a good use effect.

[0017] 3. In the present invention, a fixing component is provided, and when the ventilation duct arranged on the outer wall of the shell is connected with the air duct, it is only necessary to pull the handle, and the handle drives the integrated plate to move, and the integrated plate drives the compression spring rod to move, so that it squeezes the third spring to form a compressed state, and the integrated plate also drives the connecting rod to move, and the connecting rod drives the first pin to move, so that it moves out of a pin hole on the side wall of the air duct, and the integrated plate also drives the first long rod to move, and the first long rod drives the first toothed bar to move, and the first toothed bar is meshed with the first gear, so that it drives the first gear to rotate synchronously, and the first gear rotates while driving the first threaded barrel to rotate, and the inner wall of the first threaded barrel is threadedly connected with the first threaded rod, and when the first threaded barrel rotates, it drives the first threaded rod to move on its inner wall, and the first threaded rod simultaneously drives the second pin to move, so that it is moved out of the pin hole arranged on the side wall of the air duct. The gear wheel is engaged with the second gear and the gear is engaged with the gear of the first gear and the gear is engaged with the gear of the second gear, so that the gear wheel can rotate simultaneously with the gear wheel, and the gear wheel can rotate simultaneously with the gear wheel.
