[0032] See also Figure 1 , Figure 2 and Figure 5 , a rotating shaft 8 is installed on the inner wall of the fixed ring 2, and a motor 9 is installed on the inner wall of the body 1. The output end of the motor 9 is fixedly connected to the rear end of the rotating shaft 8, and the motor 9 can drive the rotating shaft 8 to rotate. When the rotating shaft 8 rotates, it can drive the fixed ring 2 to rotate, so that the multiple fan blades 6 can make a circular motion, and the outside air is drawn into the body 1. A filter 10 is installed on the inner wall of the body 1, and two scrapers 11 are fixedly connected to the front end of the rotating shaft 8. Both scrapers 11 are in contact with the filter 10. The installation of the filter 10 can filter the airflow entering the body 1, and the filter 10 can be cleaned by the cooperation of the scrapers 11 to avoid clogging of the filter 10. The ends of the two scrapers 11 away from each other are rotatably connected with rollers, and both rollers are in contact with the inner wall of the body 1. The installation of the rollers can facilitate the scraper 11 to contact with the arc block 17 during the swinging process, so as to avoid the long-term friction between the scraper 11 and the arc block 17 and affect the service life of the scraper 11.

[0033] See also Figure 3 , Figure 4 and Figure 5A baffle plate 12 is installed on the front of the body 1, and a plurality of air inlets 13 are opened on the front of the baffle plate 12. The installation of the baffle plate 12 can prevent large impurities from entering the body 1 and prevent impurities from affecting the normal operation of the body 1.

[0034] An energy-saving fan in the present embodiment can cushion multiple fan blades when the rotating shaft stops by installing a spring and cooperating with a T-shaped slider, thereby preventing the inertial force from being transmitted to the multiple fan blades and causing the connection between the fan blades and the fixed ring to break, and can effectively increase the service life of the fan blades. By installing a scraper, the filter can be cleaned to prevent the filter from being blocked.

[0035] The working principle of the above embodiment is as follows: first, the motor 9 is started, and the motor 9 can drive the rotating shaft 8 to rotate. During the rotation process, the rotating shaft 8 can drive the fixed ring 2 to rotate, thereby enabling the plurality of fan blades 6 to make a circular motion, and extract the outside air and transport the air. The airflow entering the body 1 will be filtered by the filter 10, and during the rotation process, the rotating shaft 8 can drive the two scrapers 11 to clean the filter 10 to prevent the filter 10 from being clogged by impurities. When the scraper 11 makes a circular motion, when the roller contacts the arc block 17, the scraper 11 moves in a circular motion. When the motor 9 stops working, the rotating shaft 8 stops rotating. At this time, the T-shaped slider 4 can slide in the sliding groove 3 and squeeze the spring 5, so that the spring 5 can buffer the inertia force of the T-shaped slider 4 through its own deformation force, thereby avoiding the centrifugal inertia from acting on the fan blade 6 and prolonging the service life of the fan blade 6, and can effectively improve the service life of the fan blade 6.
