[0015] The present invention provides a motor heat dissipation structure for a floor scrubber. It has the following beneficial effects:

[0016] (1) This invention can utilize the water inside the floor scrubber to flow into the water pipe, and the water inside the water pipe will cool the AC motor. When the fan is started, the fan will blow towards the water pipe and the AC motor, which can improve the heat exchange efficiency between the AC motor and the water pipe and prevent the AC motor from overheating.

[0017] (2) The invention allows the air outside the device to enter the interior of the machine body through the filter plate 1 to increase the air circulation. When the connecting block moves up and down, the connecting block will drive the scraper to move up and down. When the scraper moves up and down, the scraper will scrape the impurities adhered to the surface of the filter plate 1 downward to prevent the filter plate 1 from being blocked by impurities, which will cause the air inside the machine body to be unable to circulate, thereby causing the temperature of the AC motor to rise. When the short rod 1 continues to move downward, the short rod 1 will drive the rotating plate to rotate. When the rotating plate rotates, the impurities and dust on the top of the rotating plate will fall into the collection box for collection. When the short rod 1 moves upward, the short rod 1 will break away from the contact with the rotating plate. At this time, the rotating plate will return to its original position under the elastic force of the spring 1, which can effectively prevent the impurities inside the collection box from being blown up by the wind and causing pollution to the ground.

[0018] (3) In this invention, the water inside the water tank will flow into the water pipe. The water entering the water pipe will dissipate heat for the AC motor. When the sponge moves up and down, the sponge will absorb the water droplets adhering to the surface of the water pipe, which can effectively prevent the water droplets from increasing and making the inside of the body wet, thereby affecting the operation of the AC motor. When the sponge continues to move downward, the filter plate 2 will squeeze the sponge. At this time, the water inside the sponge will pass through the filter plate 2 and enter the collection ring, which can effectively keep the sponge dry and improve the absorption efficiency of the sponge. When there is water inside the collection ring, the water inside the collection ring will flow out of the body through the drainage rack, which can effectively prevent the water inside the collection ring from accumulating more and more.

[0019] (4) In this invention, after the water inside the water pipe passes through the high temperature of the AC motor, the heat of the AC motor will be replaced by the water. At this time, the water temperature inside the water pipe will become higher, which will reduce the heat dissipation efficiency. When the baffle plate 2 moves backward, the circular holes on the upper and lower sides of the baffle plate 2 will intersect with the water pipe. At this time, the water inside the water pipe will flow into the brush plate, making it easier for the brush plate to clean the floor, improving the cleaning effect of the brush plate, and allowing the water with a lower temperature inside the water tank to flow into the water pipe after the temperature rises and flows out, so as to dissipate heat again. When the push block moves backward, the push block will shake the desiccant inside the drying box, which can effectively prevent the desiccant from being in a static state for a long time and causing caking. When the desiccant moves, the desiccant can increase the contact area with the air, so that the desiccant has a better absorption effect. BRIEF DESCRIPTION OF THE DRAWINGS
