Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-3 A fresh air purification device for a dust-free workshop comprises an air supply duct 1, an air inlet 2 is arranged on one side of the air supply duct 1, a first barrier net 3 is arranged on one side of the air supply duct 1, the first barrier net 3 is clamped at the outer end of the air inlet 2, a filter net 4 is fixedly connected to the inside of the air inlet 2, a cleaning component 5 is arranged at the outer end of the air supply duct 1, the cleaning component 5 comprises a support shaft 503 rotatably connected to the inside of the air supply duct 1, the support shaft 503 is arranged between the first barrier net 3 and the filter net 4, a rotating plate 504 is fixedly connected to the outer end of the support shaft 503, and a brush 505 is fixedly connected to the outer end of the rotating plate 504. The purpose of this arrangement is that during the air supply process of the air supply duct 1, the first barrier net 3 at the outer end of the air inlet 2 and the filter 4 inside it absorb some dust and flying catkins. After long-term use, the first barrier net 3 and the filter 4 are very likely to be blocked. At this time, the air intake efficiency of the air supply duct 1 is reduced, and the workload of the fan 11 is increased. During the air intake process, the rotating plate 504 and the ground hole brush 505 at the outer end of the support shaft 503 swing between the first barrier net 3 and the filter 4, thereby cleaning the inner side of the first barrier net 3 and the outer side of the filter 4 to prevent the pores from being blocked.

The purpose of this arrangement is to improve the filtering effect of the filter 4 on the air because the aperture of the filter 4 is smaller than the aperture of the first barrier net 3.

[0025] Preferably, the rotating plate 504 is Y-shaped, and the cleaning assembly 5 further includes a connecting belt 507 sleeved inside the pulley 502. The pulley 502 is provided with three groups. The outer end of the cavity mounting plate 501 is fixedly connected to a servo motor 506, and the output end of the servo motor 506 is fixedly connected to one of the pulleys 502. The purpose of this arrangement is that during the cleaning process, the servo motor 506 drives one group of pulleys 502 to rotate inside the cavity mounting plate 501, and the connecting belt 507 drives the three groups of pulleys 502 to rotate simultaneously, so that the three groups of rotating plates 504 rotate together, thereby improving the cleaning effect of the first barrier net 3 and the filter net 4.

The purpose of this arrangement is that the dust removal bags 9 inside the two groups of clamping rings 8 can filter dust and flying catkins in the air, thereby enhancing the air purification effect.

[0028] Preferably, an air cavity 10 is provided inside the air supply duct 1, a fan 11 is fixedly connected inside the air cavity 10, an air outlet 12 is provided on one side of the air supply duct 1, and the air inlet and the air outlet of the fan 11 are respectively connected to the filter chamber 6 and the air outlet 12.
