[0017] 2. The present invention drives the second rotating shaft to rotate through the operation of the servo motor, and then drives the second gear to rotate through the cooperation between the first gear and the second gear, and then drives the transmission belt to rotate, and then drives the two rotating brush assemblies to rotate in the opposite direction. When the servo motor is working, the electromagnetic valve is opened, so that the cleaning liquid in the cleaning water tank is pumped by the water pump and transported to the buffer water tank, and then sprayed through the spray port to the surface of the electric oven shell that needs to be cleaned. During the rotation of the rotating brush assembly on one side, the cleaning liquid on the surface will be rubbed, so as to clean the oil stains on the outside of the electric oven, and through the setting of the scraper assembly, the cleaning liquid on the rotating brush is rubbed on the surface of the electric oven shell.

During the rotation of the rotating brush assembly on the other side, the mixture is adsorbed by the cleaning cloth and is scraped off when it rotates to the position of the third scraper and the fourth scraper. Then, under the guidance of the first fixed block, the telescopic baffle bar, the second fixed block and the third fixed plate, the liquid will fall to the inner side of the sewage tank through the telescopic rubber plate and be collected, so that the outside of the electric oven can be effectively cleaned.

[0018] 3. In the process of cleaning the outer shell of a cylindrical electric oven, the telescopic soft plate will be depressed in the middle when being pressed down, and the two brushes will remain stationary, so as to achieve the purpose of fitting the cylindrical surface, and at the same time, the outer sides of the two rotating brush assemblies will fit the outer shell of the cylindrical electric oven, so as to achieve the purpose of cleaning the outer shell of the cylindrical electric oven, which is conducive to cleaning the outer shells of square and cylindrical electric ovens, and makes the use range of the equipment wider.

[0019] 4. In the process of the rotating brush assembly being extended, the two positioning arc plates are simultaneously driven away, and the first scraper slides along the second convex slide rail so that the first scraper and the second scraper are unfolded, so as to adapt to the length of the rotating brush assembly and scrape off the cleaning liquid and oily mixture on the outside of the rotating brush assembly, thereby ensuring that the outer surface of the rotating brush assembly on one side is clean and tidy for the next round of cleaning work.

[0020] 5. In the process of the rotating brush assembly being extended, the two third fixing plates of the present invention will be driven away at the same time, and the third fixing plate will drive the two second fixing blocks and the two fourth scrapers away, thereby making the third scraper and the fourth scraper unfold, and at the same time the telescopic rubber plate and the telescopic baffle will be extended, thereby ensuring the scraping and guiding of the mixture, and effectively collecting the mixture, thereby avoiding the situation where the mixture is exposed and pollutes the working environment.

[0021] 6. In the present invention, when the rotating brush assembly is extended, the two third limiting square plates are driven away by the two L-shaped telescopic plates, and under the positioning of the L-shaped fixed plate, the sewage tank is located in the middle of the first telescopic square tube. In the process of the rotating brush assembly being extended, the two second limiting square tubes are moved away, and under the positioning of the second fixed plate, the positions of the first telescopic sleeve and the cleaning water tank remain unchanged relative to the position of the first telescopic square tube, thereby ensuring effective spraying of the cleaning liquid at the cleaning position and effective collection of the mixture after cleaning.

Then, under the guidance of the first fixed block 3065, the telescopic stop bar 3066, the second fixed block 3067 and the third fixed plate 307, the liquid falls to the inner side of the sewage tank 302 through the telescopic rubber plate 3064 and is collected.

[0044] In the process of cleaning the cylindrical electric oven shell, the telescopic soft plate 104 will be sunken in the middle when being pressed down, and the two sides will remain stationary to achieve the purpose of fitting the cylindrical surface, and at the same time, the outer sides of the two rotating brush assemblies 102 will fit the cylindrical electric oven shell, thereby achieving the purpose of cleaning the cylindrical electric oven shell;

[0045] When the rotating brush assembly 102 is stretched, the two positioning arc plates 1091 will be driven away at the same time, and at the same time, the first scraper 1093 will slide along the second convex slide rail 1095 so that the first scraper 1093 and the second scraper 1094 are unfolded, and the length of the rotating brush assembly 102 can be adapted to scrape off the cleaning liquid and oily mixture on the outside of the rotating brush assembly 102, thereby ensuring that the outer surface of the rotating brush assembly 102 on one side is clean enough for the next round of cleaning work;

[0046] When the rotating brush assembly 102 is stretched, the two third fixing plates 307 are simultaneously driven away, and the third fixing plate 307 drives the two second fixing blocks 3067 and the two fourth scrapers 3062 away, thereby making the third scraper 3061 and the fourth scraper 3062 unfold, and at the same time, the telescopic rubber plate 3064 and the telescopic blocking bar 3066 are stretched, thereby ensuring the scraping and guiding of the mixture, and effectively collecting the mixture, thereby preventing the mixture from being exposed and polluting the working environment.

[0047] During the process of the rotating brush assembly 102 being elongated, the two third limiting square plates 305 will be driven away by the two L-shaped telescopic plates 304, and under the positioning of the L-shaped fixed plate 301, the position of the sewage tank 302 is located in the middle of the first telescopic square tube 10102, and during the process of the rotating brush assembly 102 being elongated, the two second limiting square tubes 205 are moved away, and under the positioning of the second fixed plate 203, the positions of the first telescopic sleeve 202 and the cleaning water tank 206 will remain unchanged relative to the position of the first telescopic square tube 10102, ensuring effective spraying of cleaning liquid on the cleaning position and effective collection of the cleaning mixture.
