[0002] At present, a fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas delivery machinery. The fans usually referred to include ventilators, blowers, and wind turbines. They are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and air intake of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and selection of grains, inflation and propulsion of wind tunnel wind sources and hovercraft, etc. After the fan has been working for a long time, a lot of dust will adhere to the air inlet of the fan, and the dust needs to be manually cleaned regularly. Manual cleaning is time-consuming and labor-intensive, and the efficiency is low.

The scraper is rotated until the insertion rod is aligned with the circular plate and then released. The spring drives the insertion rod to move into the slot in the circular plate and is fixed through elastic force. At this time, the starting motor drives the third rotating shaft to rotate through the cooperation of the first bevel gear and the second bevel gear. The rotation of the third rotating shaft drives the threaded rod to rotate. The rotation of the threaded rod drives the baffle to move to block half of the filter plate and then stops.

[0026] See also Figure 3 The adjustment component includes a threaded rod 142 and a guide rod 143. A third rotating shaft 144 and a fixedly installed guide rod 143 are symmetrically installed on one side of the inner wall of the support box 140.

The sealing strip 122 cooperates with the baffle 141 to prevent the baffle 141 from blocking half of the filter plate 120, causing the wind speed to increase and pass through the gap to create negative pressure and absorb dust.

[0031] Working principle: when cleaning is needed, the pull plate 135 is pulled to drive the pull rod 134 to move, and the pull rod 134 moves to drive the insertion rod 132 to move out of the slot and squeeze the spring 133 at the same time, and the scraper 130 is rotated until the insertion rod 132 is aligned with the circular plate 121 and then released. The spring 133 drives the insertion rod 132 to move to the slot in the circular plate 121 and is fixed through the elastic force. At this time, the starting motor 145 drives the third rotating shaft 144 to rotate through the first bevel gear and the second bevel gear. The rotation of the third rotating shaft 144 drives the threaded rod 142 to rotate. The rotation of the threaded rod 142 drives the baffle 141 to move to block half of the filter plate 120 and then stop. The filter plate 120 rotates slowly through the cooperation of the circular plate 121, the first rotating shaft, the planetary gear 112, the second rotating shaft and the fan 111. At this time, the scraper 130 scrapes off the dust on one side of the filter plate 120, and at the same time, the other side of the filter plate 120 is blocked by the baffle 141, and there is no adsorption of the incoming air, so that the dust can fall naturally.
