[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0028] Example:

[0029] like Figure 1 As shown, a display screen 4 cleaning device includes: a mobile trolley 1, a cleaning component 2, a drying component 3, and a display screen 4. The mobile trolley 1 is slidably disposed above the display screen 4, the cleaning component 2 is disposed inside the mobile trolley 1, and the drying component 3 is also disposed on the trolley body 11.

[0030] The mobile trolley 1 includes a trolley body 11 and a horizontal drive device 12. The trolley body 11 has a rectangular structure with openings at the top and bottom to facilitate control of the contact between the cleaning component 2 and the display screen 4. Wheels 113, which are omnidirectional wheels, are located at the four corners of the bottom of the trolley body 11. The horizontal drive device 12 can be a cylinder, with its piston rod connected to the trolley body 11 for pulling the trolley body 11 to move.

[0031] like Figure 2 As shown, the cleaning assembly 2 includes: a fixed rod 21, a cleaning brush 22, a vertical drive device 23, a rotary drive device 24, and a spray device 25. The fixed rod 21 is horizontally arranged on the moving trolley 1 and perpendicular to the sliding trajectory of the moving trolley 1. The fixed rod 21 can move up and down on the trolley body 11. The cleaning brush 22 has a cylindrical structure, and its axial ends are connected to the fixed rod 21. The vertical drive device 23 is a cylinder, and the cylinder piston rod is connected to the fixed rod 21 to drive the cleaning brush 22 on the fixed rod 21 to move up and down.

[0032] The rotary drive device 24 includes a motor 241, a drive gear 242, and a driven gear 243. The tail of the motor 241 is mounted on a support rod 244, which is vertically connected to a fixed rod 21. The drive gear 242 is fixedly connected to the output shaft at the front end of the motor 241. The driven gear 243 is located circumferentially on the cleaning brush 22 near the end of the motor 241. The drive gear 242 meshes with the driven gear 243, driving the cleaning brush 22 to rotate.

[0033] More preferably, a motor slide groove 111 and a fixing rod slide groove 112 are provided on the side wall of the vehicle body 11, the motor 241 is slidably connected to the motor slide groove 111, and the fixing rod 21 is slidably connected to the fixing rod slide groove 112.

[0034] In this embodiment, the cleaning brush 22 includes a bristle layer 221 and a water inlet layer 222. The water inlet layer 222 is fitted inside the bristle layer 221, and the bristle layer 221 can rotate relative to the water inlet layer 222. The driven gear 243 is disposed at the end of the bristle layer 221 and is used to drive the bristle layer 221 to rotate. The bristles on the bristle layer 221 are soft bristles. The water inlet layer 222 is provided with a water inlet channel 223. The inlet of the water inlet channel 223 is connected to the spray device 25. A plurality of water outlet channels 224 are arranged radially on the bristle layer 221, and the outlet of the water inlet channel 223 is connected to the water outlet channel 224. More preferably, the water inlet channel 223 includes a first water inlet channel 223 arranged axially along the water inlet layer 222 and a second water inlet channel 223 arranged radially along the water inlet layer 222. The second water inlet channel 223 is arranged relatively lower and there is only one row. The first water inlet channel 223 is connected to the second water inlet channel 223.

[0035] The fixed rod 21 has a hollow structure inside, and the water inlet pipe of the spray device 25 is installed inside the fixed rod 21, so that the water inlet channel 223 is connected to the spray device 25.

[0036] like Figure 3 As shown, in this invention, the cleaning brush 22 may not be divided into two layers: a bristle layer 221 and a water inlet layer 222, but may be a single unit consisting of bristles and a rotating shaft. The spray device 25 is mounted on the vehicle body 11 and aligned with the cleaning brush 22, which is rotatably mounted on the fixed rod 21.

[0037] like Figure 2 As shown, the drying assembly 3 includes: a convex frame, a rotating sleeve 33, a roller 34, and a blower 35. The rotating sleeve 33 is rotatably mounted on the fixing rods 21 at both ends of the cleaning brush 22. The open end of the convex frame is fixedly connected to the rotating sleeve 33. To position the roller 34 and the blower 35 at different heights, the convex frame is divided into a first convex frame 31 and a second convex frame 32. The second convex frame 32 is located outside the first convex frame 31, and the second convex frame 32 forms a certain angle with the first convex frame 31, with the second convex frame 32 on top and the first convex frame 31 on the bottom. The roller 34 is fitted onto the closed end of the first convex frame 31, and the blower 35 is fitted onto the closed end of the second convex frame 32. Both the roller 34 and the blower 35 are located on one side of the cleaning brush 22, with the roller 34 positioned lower than the blower 35.

[0038] To control the positions of the roller 34 and the blower 35, the drying assembly 3 also includes a spring 36 and a positioning rod 37. One end of the spring 36 is fixedly connected to the upper part of the vehicle body 11, and the other end of the spring 36 is fixedly connected to the second convex frame 32. The positioning rod 37 is fixedly installed on the side wall of the vehicle body 11. When the cleaning brush 22 moves upward, it can interfere with the convex frame, causing the convex frame to rotate downward.

[0039] In this invention, the cleaning component 2 and the drying component 3 have three states. For example... Figure 4 As shown, the first state is deep cleaning. The cleaning brush 22 is deeply covered with the display screen 4. The shaped frame is attached to the positioning rod 37 under the action of the spring 36. At this time, the roller 34 and the blower 35 are above the display screen 4 and have a certain distance from the display screen 4. The blower 35 is not activated in the deep cleaning state.

[0040] like Figure 5 As shown, the second state is a simple cleaning state. The cleaning brush 22 moves upward relative to the deep cleaning state, and the bristles of the cleaning brush 22 just come into contact with the display screen 4. Because the rotating sleeve 33 moves upward with the cleaning brush 22, the positioning rod 37 hinders the upward movement of the shaped frame during the upward movement of the shaped frame, causing the shaped frame to rotate downward relative to the screen. At this time, the roller 34 is attached to the display screen 4, and the blower 35 is above the display screen 4, with a certain distance between them. In the simple cleaning state, the blower 35 is not activated.

[0041] like Figure 6 As shown, the third state is the drying state. The cleaning brush 22 continues to move upwards in the relatively simple cleaning state. The bristles of the cleaning brush 22 do not contact the display screen 4 because the rotating sleeve 33 moves upwards with the cleaning brush 22. During the upward movement of the shaped frame, the positioning rod 37 hinders the upward movement of the shaped frame, causing the shaped frame to rotate downwards relatively. At this time, the roller 34 is attached to the display screen 4, and the blower 35 is above the display screen 4. However, compared with the above two states, the distance between the blower 35 and the display screen 4 is shortened. The blower 35 is activated in the drying state.

[0042] It should be noted that the positioning rod 37 interferes with the convex frame during the upward movement of the cleaning brush 22. When the cleaning brush 22 enters three different states during its upward movement, the blower 35 and roller 34 also correspondingly enter three states. The position of the positioning rod 37 is the focal point of the convex frame's three states. The spring 36 is used for resetting; when the cleaning brush 22 moves downward, the spring 36 pulls the convex frame upward.

[0043] In use, first place the display screen 4 horizontally. At this time, the moving trolley 1 is located on the right side of the display screen 4. Then, start the vertical drive device 23 so that the cleaning brush 22 moves downward under the drive of the fixed rod 21 until the cleaning component 2 and the drying component 3 are adjusted to the deep cleaning state. Then, start the rotary drive device 24 and the spray device 25 to spray water on the display screen 4. The cleaning brush 22 rotates to clean. At the same time, start the horizontal drive device 12 to move the trolley 11 from the right side of the display screen 4 to the left side, and then return to the right side of the display screen 4.

[0044] After deep cleaning of the display screen 4, the moving trolley 1 is located on the right side of the display screen 4. The vertical drive device 23 is activated, causing the cleaning brush 22 to move upward under the drive of the fixed rod 21 until the cleaning component 2 and the drying component 3 are adjusted to a simple cleaning state. Then the spray device 25 is turned off, and the rotary drive device 24 is activated. The cleaning brush 22 rotates to perform a simple cleaning of the display screen 4. The roller 34 can fit against the display screen 4. At the same time, the horizontal drive device 12 is activated, driving the trolley 11 from the right side of the display screen 4 to the left side, and then back to the right side of the display screen 4. The roller 34 moves with the trolley 11 to scrape off the water droplets on the display screen 4.

[0045] After a simple cleaning of the display screen 4, the moving trolley 1 is positioned to the right of the display screen 4. The vertical drive device 23 is activated, causing the cleaning brush 22 to move upwards under the influence of the fixed rod 21 until the cleaning assembly 2 and the drying assembly 3 are adjusted to the drying state. Then, the rotary drive device 24 is turned off, and the blower 35 is activated. Simultaneously, the horizontal drive device 12 is activated, moving the trolley body 11 from the right side of the display screen 4 to the left side, and then back to the right side of the display screen 4. The roller 34 moves with the trolley body 11, initially scraping off the water droplets on the display screen 4, while the blower 35 dries any remaining water droplets. After completing these three steps, the cleaning process for the display screen 4 is finished. The cleaned display screen 4 is removed, and a new display screen 4 to be cleaned is placed on top, and the cleaning process continues according to the above steps.
