The output end of the driving motor 3 is fixedly connected with the driving gear 31 , and the driving gear 31 is meshedly connected with the outer surface of the rotating gear cylinder 27 .

[0054] Cleaning process of protective cover 24:

[0055] In practical applications, by starting the driving motor 3, the driving motor 3 drives the driving gear 31 to rotate on the lower surface of the mounting ring plate 23 through the output end. Under the meshing action of the driving gear 31 and the rotating gear cylinder 27, the rotating driving gear 31 drives the rotating gear cylinder 27 to rotate on the lower surface of the mounting ring plate 23. The rotating rotating gear cylinder 27 drives the three L blocks 271 on its lower surface to rotate synchronously. The three L blocks 271 drive the first gear ring 272 to rotate around the axis of the rotating gear cylinder 27. Under the meshing action of the first gear ring 272 and the first gear 256, the rotating first gear ring 272 drives the first gear 256 inside thereof to rotate on the upper surface of the U-shaped plate 255. The two first gears 256 drive the eccentric column 257 on its lower surface to rotate around the axis of the first gear 256. Under the limiting action of the groove 2542, the rotating eccentric column 257 drives the pushing block 254 to slide back and forth along the inner wall of the U-shaped plate 255 through the transverse groove 2542. Under the limiting action of the pushing groove 2541, the reciprocatingly sliding pushing block 254 drives the pushing column 253 to reciprocate around the axis of the protective cover 24 through the pushing groove 2541. The two pushing columns 253 drive the swivel 251 to reciprocate around the axis of the protective cover 24 on the upper surface connected to the lower plate 233. The swivel 251 drives the two cleaning scrapers 252 on its circumferential inner surface to reciprocate around the axis of the protective cover 24. Under the high-frequency reciprocating rotation of the two cleaning scrapers 252, the two cleaning scrapers 252 are located inside the protective cover 24 to scrape off the splashes attached to both sides of the inner surface of the protective cover 24.

[0056] The process of moving the protective cover 24:

[0057] In actual application, when the rotating gear cylinder 27 is located on the lower surface of the mounting ring plate 23 and rotates, the rotating gear cylinder 27 drives the special-shaped slide rail 273 on its circumferential outer surface to rotate synchronously, so that the arc rail 2731 and the pushing folding rail 2732 rotate around the axis of the protective cover 24, and the arc rail 2731 and the pushing folding rail 2732 are cyclically and alternately connected with the top end of the rotating handle 263 in a sliding manner. When the rotating handle 263 is slidably connected with the arc rail 2731, the rotating handle 263 is limited under the limiting action of the arc rail 2731, so that the position of the protective cover 24 on the lower surface of the connecting lower plate 233 is fixed. When the rotating handle 263 is slidably connected with the pushing folding rail 2732, the pushing folding rail 2732 is pushed to rotate under the limiting action of the pushing folding rail 2732. The handle 263 rotates around the axis of the rotating plate 262 for one circle, so that the rotating handle 263 drives the rotating plate 262 located on the lower surface connected to the middle plate 232 to rotate for one circle, and the rotating plate 262 drives the toggle column 2621 and the arc block 2622 on its lower surface to rotate. After the arc block 2622 is separated from the arc groove, the toggle column 2621 is slidably connected to the toggle ring 261 through the straight groove, so that the toggle column 2621 pushes the toggle ring 261 to rotate around the axis of the protective cover 24 by a certain angle through the straight groove, and the toggle ring 261 drives the protective cover 24 on its inner surface to deflect around its own axis by a certain angle, and the arc block 2622 is slidably connected to the toggle ring 261 again through the arc groove, and the toggle ring 261 and the protective cover 24 are limited again, and the position of the protective cover 24 on the lower surface of the lower plate 233 is fixed again.

[0058] In summary, the two cleaning scrapers 252 located on both sides of the inner surface of the protective cover 24 are driven by the rotating ring 251 to reciprocate at a high frequency, and the two cleaning scrapers 252 scrape the splashes attached to both sides of the inner surface of the protective cover 24. The protective cover 24 is driven by the toggle ring 261 to deflect around its own axis at a certain angle at regular intervals on the lower surface connected to the lower plate 233. After the protective cover 24 deflects around its own axis for one circle, the splashes attached to the inner surface of the protective cover 24 are scraped off as a whole under the scraping action of the cleaning scrapers 252, thereby improving the smoothness of the surface of the protective cover 24, thereby increasing the surface tension of the protective cover 24, and reducing the difficulty of the splashes adhering to the protective cover 24.

[0059] In summary, the present application has the following advantages by adopting the cleaning member 25 and the toggle member 26:

[0060] Advantage 1: By setting a swivel 251 on the connecting lower plate 233 to rotate around the axis of the protective cover 24 at a high frequency, the swivel 251 drives the two cleaning scrapers 252 to reciprocate at a high frequency on the inner surface of the protective cover 24, thereby scraping off the splashes attached to both sides of the inner surface of the protective cover 24.

[0061] Advantage two, by setting the toggle ring 261 to intermittently rotate on the lower surface connected to the lower plate 233, the toggle ring 261 drives the protective cover 24 to deflect a certain angle around its own axis at regular intervals, so that the two cleaning scrapers 252 can scrape away the splashes at different positions on the inner surface of the protective cover 24, thereby improving the smoothness of the surface of the protective cover 24, thereby increasing the surface tension of the protective cover 24, and reducing the difficulty of the splashes adhering to the protective cover 24.

[0062] Advantage three, by setting the first gear ring 272 and the special-shaped slide rail 273, the first gear ring 272 drives the first gear 256 to rotate multiple circles, and the special-shaped slide rail 273 drives the rotating handle 263 to rotate one circle, so that the protective cover 24 can only deflect once after the two cleaning scrapers 252 swing back and forth multiple times.

[0063] Advantage four: by setting the cleaning scraper 252 to reciprocate at a high frequency on the inner surface of the protective cover 24, the cleaning scraper 252 can improve the scraping strength of the splashing objects on the protective cover 24, thereby preventing some splashing objects with higher adhesion strength from being difficult to separate from the protective cover 24.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
