Subsequently, during the cleaning process, the water will flow down from top to bottom, which greatly reduces the cleaning work and improves the efficiency; the third lead screw combination mechanism 116 drives one end of the two connecting rods 117 to move, so that the two connecting rods 117 lift the two side support plates 115, so that the two side support plates 115 rotate to a state flush with the connecting square plate 105. At this moment, the square plate on the second square spray plate 114 just fits into the square groove of the first square spray plate 113. At this moment, the two second square spray plates 114 and the first square spray plate 113 are integrated; when the motor in the connecting square plate 105 drives the first square spray plate 113 to rotate, the first square spray plate 113 will drive the two second square spray plates 114 to rotate together, and the rotation angle is an acute angle.

Subsequently, the second lead screw assembly 109 drives the second electric cylinder 110, the semi-circular plate 111 and the tool to move forward, so that the tool is pulled out from the connecting frame 204. The motor on the sliding support plate 107 drives the slider of the first lead screw assembly 108 to move, thereby driving the second lead screw assembly 109 to move up and down, so as to adjust to the height required for spraying the color painting. Subsequently, the second lead screw assembly 109 drives the second electric cylinder 110, the semi-circular plate 111 and the required tool to move forward, so that the required tool moves to a suitable position, and then the wall surface is sprayed; the motor on the sliding support plate 107 drives the slider of the first lead screw assembly 108 to move, thereby driving the second lead screw assembly 109 to move up and down, so as to achieve the purpose of spraying up and down; the fourth lead screw assembly 120 drives the two straight racks 121 to move left or right synchronously, so that the straight racks 121 drive the gears on the two cams 119 to rotate, further driving the two cams 119 to rotate, thereby driving the two sliding support plates 107 to move left or right, thereby driving the other mechanisms on the sliding support plates 107 to move, so as to achieve the purpose of spraying while moving left.

[0036] In an alternative embodiment of the embodiment of the present invention, as Figures 9 - 11 shown, the bottom cleaning part 1 further includes: a connecting bracket 118, a cam 119, a fourth lead screw assembly 120 and a straight rack 121; The connecting bracket 118 is fixedly installed on the supporting bottom plate 101; there are two cams 119, and the two cams 119 are respectively rotatably installed on the connecting bracket 118.

The thread rotation direction of the fourth lead screw combination mechanism 120 is single, so the moving directions of the two straight racks 121 are synchronized. As a result, the rotation directions of the gears on the two cams 119 are the same, and the rotation directions of the two cams 119 are the same.

[0038] In an alternative embodiment of the embodiment of the present invention, as Figures 12 - 13 shown, the upper switching part 2 includes: a large scraper 205, a roller 206, a large spray head 207, and a small spray head 208; The large scraper 205, the roller 206, the large spray head 207, and the small spray head 208 are respectively inserted into each buckle of the connecting frame 204; the large spray head 207 and the small spray head 208 are respectively connected to a corresponding storage tank 112 through pipelines.

[0039] Working principle: This device automates the cleaning of the wall to improve the firmness of the sprayed coating; moreover, this device can also spray the wall by switching a variety of spraying tools, which improves the spraying efficiency and increases the diversity of spraying types while spraying; this device can also prevent the paint from falling below during the spraying process and affecting the spraying effect below; To improve the firmness of the sprayed coating, it is necessary to clean the wall surface in advance. During the cleaning process, the connecting square plate 105 and the side support plate 115 do not contact the wall. First, the two first electric cylinders 104 expand and contract to drive the connecting square plate 105 and the side support plate 115 to rise, so that the first square water spraying plate 113 and the two second square water spraying plates 114 rise to a higher position on the wall. Subsequently, during the cleaning process, the water will flow down from top to bottom, which greatly reduces the cleaning work and improves the efficiency. The third lead screw combination mechanism 116 drives one end of the two connecting rods 117 to move, so that the two connecting rods 117 lift the two side support plates 115, so that the two side support plates 115 rotate to a state flush with the connecting square plate 105. At this moment, the square plate on the second square water spraying plate 114 just fits into the square groove of the first square water spraying plate 113. At this moment, the two second square water spraying plates 114 and the first square water spraying plate 113 are integrated. When the motor in the connecting square plate 105 drives the first square water spraying plate 113 to rotate, the first square water spraying plate 113 will drive the two second square water spraying plates 114 to rotate together, and the rotation angle is an acute angle. At this moment, the first square water spraying plate 113 and the two second square water spraying plates 114 rotate to a position facing the wall. Subsequently, the water is pumped from the water tank 103 through the pump and sprayed from the first square water spraying plate 113 and the two second square water spraying plates 114 to clean the wall surface. To better spray the wall, multiple spraying and smearing methods are required. The second electric cylinder 110 expands and contracts to drive the semi-circular plate 111 to move, so that the two semi-circular plates 111 clamp the required tool. Subsequently, the second lead screw combination mechanism 109 drives the second electric cylinder 110, the semi-circular plate 111 and the tool to move forward, so that the tool is pulled out from the connecting rack 204. The motor on the sliding support plate 107 drives the slider of the first lead screw combination mechanism 108 to move, so as to drive the second lead screw combination mechanism 109 to move up and down, so as to adjust to the height required for spraying and painting. Subsequently, the second lead screw combination mechanism 109 drives the second electric cylinder 110, the semi-circular plate 111 and the required tool to move forward, so that the required tool moves to a suitable position, and then the wall is sprayed. The small motor 202 drives the connecting circular plate 203 to rotate, which in turn drives the connecting rack 204 to rotate, so that the large scraper 205, the roller 206, the large sprinkler head 207, and the small sprinkler head 208 rotate, so that the large scraper 205, the roller 206, the large sprinkler head 207, and the small sprinkler head 208 change positions. The main function of the large scraper 205 is to scrape the paint on the wall. The function of the roller 206 is to evenly spread the paint on the wall. The function of the large sprinkler head 207 is to spray a larger area of the pattern. The function of the small sprinkler head 208 is to spray a smaller area of the pattern. After selecting a suitable tool, the motor on the sliding support plate 107 drives the slider of the first lead screw combination mechanism 108 to move, thereby driving the second lead screw combination mechanism 109 to move up and down, so as to achieve the purpose of spraying up and down; the fourth lead screw combination mechanism 120 drives the two straight racks 121 to move synchronously to the left or right, so that the straight racks 121 drive the gears on the two cams 119 to rotate, further driving the two cams 119 to rotate, thereby driving the two sliding support plates 107 to move to the left or right, and driving other mechanisms on the sliding support plate 107 to move, so as to achieve the purpose of spraying while moving to the left.

[0040] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
