[0043] In this embodiment, specifically, the inner wall of the outer shell 10 is evenly provided with a slide groove 8, and the outer wall of the tilting movable shell 11 is evenly provided with a slider 9. The outer wall of the slider 9 is slidably connected to the inner wall of the slide groove 8. Through the above setting, the slider 9 is slid in the slide groove 8, which can not only assist the tilting movable shell 11 to move, but also stabilize the moving position of the tilting movable shell 11.

[0044] In this embodiment, specifically, a limiting plate 27 is provided on the inner wall of the liquid inlet hole 26, and the switch door 28 is rotatably connected to the inner wall of the liquid inlet hole 26 through a bearing, and the lower surface of the switch door 28 is in contact with the upper surface of the limiting plate 27. Through the above arrangement, the actual user holds the switch door 28 and rotates it, and the switch door 28 is detached from the limiting plate 27, thereby removing the switch door 28 from the liquid inlet hole 26, making it convenient for the actual user to put the cleaning agent into the liquid storage chamber 25 through the liquid inlet hole 26.

[0045] In this embodiment, specifically, universal wheels 2 are evenly provided on the lower surface of the outer shell 10, and U-shaped handles 3 are symmetrically provided on the front surface of the outer shell 10.

[0046] When the present invention is working: the actual user holds the switch door 28 and rotates it, and the switch door 28 detaches from the limit plate 27, thereby moving the switch door 28 out of the liquid inlet hole 26, making it convenient for the actual user to put the cleaning agent into the liquid storage chamber 25 through the liquid inlet hole 26. When the cleaning agent in the liquid storage chamber 25 is full, the actual user holds the switch door 28 and rotates it in the opposite direction to move the switch door 28 to the limit plate 27. The switch door 28 is used to block the liquid inlet hole 26.

[0047] After that, the actual user controls the electric push rod 14 to start through the control panel 4. The piston rod of the electric push rod 14 drives the tilting movable shell 11 to move upward, and the tilting movable shell 11 drives the triangular arc shell 120 and the central control touch panel 121 to move upward, which is used to use the actual user's height to ensure the comfort of everyone.

[0048] After the actual user has finished using the central control touch panel 121, the actual user controls the servo motor 1270 to start through the control panel 4. The servo motor 1270 drives the triangular arc shell 120 and the central control touch panel 121 to rotate. The triangular arc shell 120 rotates through the connecting rod 1271. The connecting rod 1271 drives the first sprocket 1272 to rotate. The first sprocket 1272 drives the second sprocket 1274 to rotate through the chain ring 1273. The second sprocket 1274 drives the rotating rod 122 to rotate. Since the first sprocket 1272 is larger than the second sprocket 1274, the rotation speeds of the first sprocket 1272 and the second sprocket 1274 are different. The rotating rod 122 drives the tube body 125 to rotate through the wire rope 123 and the spring 124. The tube body 125 drives several flexible cleaning cloths 126 to rotate.

[0049] When the central control touch panel 121 rotates to the position of the nozzle 163, the actual user controls the liquid pump 160 to start through the control panel 4, and the liquid pump 160 draws the cleaning agent in the liquid storage chamber 25 into the connecting tube 161. The cleaning agent in the connecting tube 161 is transferred to the double-headed sealed tube 162, and the cleaning agent in the double-headed sealed tube 162 is evenly sprayed onto the central control touch panel 121 through the nozzle 163. Thereafter, the actual user controls the liquid pump 160 to shut down through the control panel 4.

[0050] Then, when the triangular arc-shaped shell 120 drives the central control touch panel 121 to rotate onto the flexible cleaning cloth 126, the tube body 125 drives several flexible cleaning cloths 126 to rotate continuously to clean the surface of the central control touch panel 121. When the triangular arc-shaped shell 120 and the central control touch panel 121 squeeze the tube body 125 to move downward, the tube body 125 squeezes the spring 124 downward to deform, so that the tube body 125 and the flexible cleaning cloth 126 can fit tightly with the triangular arc-shaped shell 120 and the central control touch panel 121, so as to be suitable for triangular arc-shaped shells 120 and central control touch panels 121 of different heights, thereby ensuring the efficiency of cleaning the central control touch panel 121. Since the wire rope 123 is flexible, it can ensure that the tube body 125 moves downward while ensuring that the rotating rod 122 drives the tube body 125 to rotate through the traction force of the wire rope 123.

[0051] After the central control touch panel 121 is cleaned, the actual user controls the servo motor 1270 to move in the opposite direction through the control panel 4. The servo motor 1270 drives the triangular arc-shaped shell 120 and the central control touch panel 121 to move in the opposite direction, so that the triangular arc-shaped shell 120 and the central control touch panel 121 are rotated by the flexible cleaning cloth 126 for cleaning again. At this time, the triangular arc-shaped shell 120 drives the central control touch panel 121 to rotate into the circular through groove 6, so that the other surfaces of the triangular arc-shaped shell 120 rotate to the outer surface of the tilted movable shell 11 to protect the central control touch panel 121.

[0052] When maintenance is required on the tube body 125 and the flexible cleaning cloth 126, the maintenance personnel use tools to turn the fixing bolt 23 out of the threaded groove 22, so as to facilitate the removal of the filter screen 15 from the first mounting groove 20, and facilitate the maintenance of the tube body 125 and the flexible cleaning cloth 126, which is convenient for the maintenance personnel to perform maintenance in the future.

[0053] The maintenance personnel releases the sub-buckle 131 from the mother buckle 132, so that the maintenance personnel can hold the U-shaped hand-held slot 5 to drive the sealing door 130 out of the square through hole 29, making it convenient for the maintenance personnel to maintain the servo motor 1270, the first sprocket 1272, the chain ring 1273 and the second sprocket 1274 to ensure stability of use.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications and substitutions within the technical scope disclosed in the present invention, and such modifications and substitutions are intended to be within the scope of protection of the present invention.
