[0035] The working principle of a fresh air fan ventilation device provided by the utility model is as follows: when it is necessary to use a fresh air fan to replace the indoor air, firstly, several pipes are assembled at 3 ventilation frames on the fresh air fan, two of which extend to the outdoors, and the remaining two pipes are placed indoors, and the pipes indoors and outdoors cooperate to discharge the turbid indoor air to the outdoors through the fresh air fan, and send the outdoor fresh air into the room through the fresh air fan. In this process, the indoor air and the outdoor air can also realize heat exchange through the heat exchange core inside the fresh air fan, and the harmful substances in the air will be removed by the filtering structure, so as to realize the provision of a steady supply of high-quality air to the indoor room. However, this operation will have the following problems: installing a fresh air fan indoors During the installation process, it is necessary to connect several pipes with the ventilation frame 3 on the fresh air fan. The existing operation is to use tools to connect each pipe by tightening multiple screws. The installation operation is cumbersome, time-consuming and labor-intensive. By setting the adjustment structure 5, the pipe is first operated to approach the ventilation frame 3 on the chassis 1, so that the installation pipe 501 is aligned with the ventilation frame 3, and then the adjustment rod 511 is rotated. The adjustment rod 511 moves along the support plate 510 toward the direction close to the chassis 1 with the help of the thread. The adjustment rod 511 drives the positioning frame 512 away from the support plate 510. In this process, the positioning frame 512 drives the limiting rod 513 to always slide along the support plate 510. After the positioning frame 512 is away from the support plate 510 for a certain distance, the support plate 510 is operated. 10 and the two clamping plates 508 between the positioning frame 512, the two clamping plates 508 and the movable frame 507 can follow the moving rod 505 to move along the fixed plate 504, slide the clamping plates 508 out of the inner wall of the positioning frame 512 and rotate to open the two clamping plates 508, then operate the installation tube 501 to approach the docking tube 502, make the docking tube 502 slide into the installation tube 501, rotate and close the two clamping plates 508, rotate the adjusting rod 511 in the opposite direction, and the adjusting rod 511 drives the positioning frame 512 to move toward the direction close to the support plate 510. During the movement of the positioning frame 512, the clamping plates 508 slide into the inner wall of the positioning frame 512, continue to rotate the adjusting rod 511, and the adjusting rod 511 drives the clamping plates 508 to move toward the mounting tube 50 1, the clamping plate 508 presses the docking tube 502 tightly against the mounting tube 501, wherein the sliding rod 506 slides with the fixing plate 504 to make the moving rod 505 more stable when moving along the fixing plate 504, and the anti-slip pad 509 increases the friction on the surface of the clamping plate 508 to make the limiting effect of the clamping plate 508 better, and the sealing ring 503 increases the air tightness between the docking tube 502 and the mounting tube 501 to make the pipeline ventilation effect better, thereby achieving, through simple operation, the ventilation pipe 4 and the ventilation frame 3 on the chassis 1 can be easily docked together, thereby improving the installation efficiency of the ventilation pipe 4 and the fresh air chassis 1, and then improving the work efficiency of the on-site installation operation of the fresh air fan, which is simple and convenient to operate and highly practical.

[0036] During the long-term use of the fresh air fan, the filter screen in the fresh air fan needs to be maintained or replaced. The maintenance operation requires the removal of the box cover 2 or the maintenance cover. The operation of removing and installing multiple screws is time-consuming and laborious. By setting the auxiliary structure 6, the limit frame 64 is first moved in the direction away from the cover plate 63, so that the limit frame 64 gradually slides out of the cover plate 63 along the box cover 2. During this process, the spring 65 is in a compressed state. After the limit frame 64 completely slides out of the cover plate 63, the cover plate 63 can be rotated to open.
