[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention provides a dustproof electromagnetic fan clutch. When in use, when the temperature is too high, the sensor will drive the clutch to rotate, the clutch drives the rotating shaft to rotate, and the rotating shaft drives the fan blades to rotate to dissipate heat from the car. When the temperature of the car is too high, the corresponding clutch will also increase the rotation speed. The clutch will generate high temperature when rotating at high speed for a long time. The rotating shaft will drive a plurality of heat dissipation fan blades to rotate during the rotation process. The wind force generated by the heat dissipation fan blades will accelerate the movement of the airflow in the clutch cover. The airflow will push open a plurality of T-shaped round blocks to discharge the heat generated by the clutch rotation, dissipate the heat of the clutch, and avoid damage to the clutch due to excessive temperature in the clutch cover. In the process of discharging hot air, dust can also be prevented from entering the clutch cover. When the clutch stops running, the T-shaped round block will be pulled back again under the action of spring 1 to close the T-shaped round groove on the clutch cover to prevent dust from entering.

[0016] (2) The dustproof electromagnetic fan clutch of the present invention drives the rotating rod to rotate during the rotation of the rotating shaft. During the heat dissipation of the clutch, the rotating rod drives the rotating plate to rotate. Under the action of centrifugal force, the rotating plate drives the arc block to move in a direction away from the center of the circle on the arc rod. When the arc block moves and contacts the arc wall of the arc groove, the arc block exposes the blocked heat dissipation hole, so that the clutch cover can achieve ventilation effect, which is convenient for heat dissipation of the clutch. When the clutch stops rotating, the reset spring pulls the arc block to reset it and block the heat dissipation hole again, so that the clutch cover is in a sealed state to prevent dust from entering.

[0017] (3) The present invention provides a dustproof electromagnetic fan clutch. Since the device is outdoors for a long time, a large amount of dust will fall on it. During the process of heat dissipation of the clutch, the outside air will enter the clutch cover. The dust in the air will first be filtered through the filter holes on the dust cover. The filtered dust will remain on the wall of the dust cover. The rotating rod will drive the scraper to rotate. The scraper will scrape the dust on the surface of the dust cover. The scraped dust will remain on the scraper. When the scraper contacts the dirt removal block, the dirt removal block will move downward and move along the scraping surface of the scraper to clean the dust on the scraper. When the arc-surface slider contacts the dirt removal block, the arc-surface slider will descend under the action of the second spring. The scraper will leave the dirt removal block and the arc-surface slider will rebound again under the action of the second spring to continue the cleaning work. At this time, the dirt removal block will be reset again under the action of the reset spring to wait for the next dust removal. The dust cleaned by the dirt removal block will be discharged from the second dust discharge slot;

[0018] (4) The present invention provides a dust-proof electromagnetic fan clutch. The air passing through the filter hole will be accompanied by fine dust impurities. When the air passes through the filter hole, it will contact the dust plate, causing the fine dust to remain on the dust plate. When the rotating rod rotates, it will drive the dust plate to rotate. During the rotation process, the dust plate will contact the fixed plate. The fixed plate will clean the fine dust on the dust plate. The cleaned dust will be discharged from the dust exhaust groove, which can further improve the dust removal effect and prevent dust from entering the clutch cover.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
