[0002] Generally, during the interior decoration process, usually workers hold a paint roller to dip into the latex paint in the paint bucket and quickly apply the latex paint on the interior wall. During the application process, it should be decisive and rapid, otherwise a large amount of latex paint on the paint roller will drip onto the ground and cause waste. However, in reality, affected by factors such as the operation level and work attitude of the workers, the waste of latex paint is very serious, and the owner cannot always monitor the workers' work, so they can only swallow their anger regarding this problem. Moreover, the manual application of latex paint is slow and inefficient, the application effect is greatly affected by the operation level and experience of the workers, and at the same time, the labor cost is very high. All these problems make the owners very much look forward to a new technology being applied to the paint operation of interior decoration to replace manual labor and solve the above problems and deficiencies.

[0038] The present invention provides a paint device for interior decoration. The paint device for interior decoration drives an overflow paint roller to roll closely against the wall through a drone 1 to complete the painting operation. The painting speed is fast, the efficiency is high, and the painting effect is good. It can be painted on vertical walls, inclined walls, interior wall tops, and floors; the drone 1 is equipped with a machine vision camera 18, which can automatically identify the position of the wall to be painted, and guide the drone 1 to drive the overflow paint roller to move to closely roll against the wall to complete the painting operation. It has a high degree of intelligence, less manual assistance work, and good practicability.

[0039] Specifically, in an embodiment of the invention, as Figure 1 , Figure 2 , Figure 6 , Figure 8 and Figure 9 shown, the paint device for interior decoration includes a drone 1 and a machine vision camera 18 and a mounting rod 8 provided on the drone 1. The machine vision camera 18 is used to capture the surrounding images of the drone 1 and transmit them to the processor inside the drone 1. After being processed by the processor, parameters such as the position coordinates, wall type, and wall size of the wall to be painted are identified. Then the processor controls the drone 1 to automatically move to the position of the wall to be painted, and realizes the overflow paint roller to closely roll against the wall to complete the painting operation. With such a design, it saves the trouble of manually controlling the drone 1 to drive the overflow paint roller to move to the wall to be painted and closely roll against the wall. It has a high degree of intelligence, less manual assistance work, and good practicability.

[0040] In this embodiment, as Figure 1 , Figure 2 , Figure 6 , Figure 8 and Figure 9 shown, one end of the mounting rod 8 is installed with an overflow paint roller. The overflow paint roller does not need to dip in paint, and the paint will overflow from the outer surface of the overflow paint roller. With such a design, it saves the trouble of frequently dipping in paint during the painting operation, and effectively improves the painting speed and efficiency.

[0041] In this embodiment, the overflow paint roller is not directly below or above the drone 1. With such a design, it can ensure that when the overflow paint roller is working, the rotor of the drone 1 will not touch the wall, making it possible for the drone 1 to drive the overflow paint roller to closely roll against the wall to complete the painting operation.

[0042] In this embodiment, as Figure 6As shown, one end of the overflow paint roller is connected to the infusion hose 14, and the other end of the infusion hose 14 is connected to the infusion pump 15. The infusion pump 15 is located inside the paint storage bucket 16. The paint storage bucket 16 is placed on the ground and is filled with paint. The infusion pump 15 extracts the paint from the paint storage bucket 16 and injects it into the overflow paint roller through the infusion hose 14, thereby achieving the technical effect that the overflow paint roller does not need to dip in paint, and the paint will overflow from the outer surface of the overflow paint roller, saving the trouble of frequently dipping in paint during the painting operation and effectively improving the painting speed and efficiency.

[0043] In the paint device for interior decoration of this embodiment, the machine vision camera 18 guides the drone 1 to drive the overflow paint roller to fly to the position of the wall to be painted by itself, and makes the overflow paint roller roll closely against the wall to complete the painting operation. During the whole process, the operator only needs to hold the remote controller 17 to confirm whether the position of the wall to be painted identified by the processor is correct. The controller and the drone 1 are wirelessly connected. After the operator holds the remote controller 17 to confirm the position of the wall to be painted, the drone 1 drives the overflow paint roller to roll closely against the wall to be painted according to the painting program set in it to complete the painting operation. It has a high degree of intelligence, less manual assistance work, good practicability, effectively replaces the manual painting operation, has a fast painting speed, high efficiency, and good painting effect.

[0044] Specifically, for vertical walls and inclined walls, the painting program preset in the drone 1 is to move up and down reciprocally to complete painting, that is Figure 1 For the paint device for interior decoration shown, the machine vision camera 18 guides the drone 1 to drive the overflow paint roller to fly to the position of the wall to be painted by itself. When the overflow paint roller is close to the wall, the preset painting program in the drone 1 controls the drone 1 to descend and drive the overflow paint roller to roll closely against the wall while descending, and at the same time the infusion pump 15 starts to input paint into the overflow paint roller, thereby realizing the painting operation;

[0045] When the overflow paint roller descends to the lower end of the vertical wall, the drone 1 drives the overflow paint roller to move to a position adjacent to the just-painted surface according to the program preset in it, and then the drone 1 ascends to realize the painting operation. When the drone 1 is about to reach the upper end of the vertical wall, the drone 1 drives the overflow paint roller to rotate 180 degrees around the horizontal axis so that Figure 1 the overflow paint roller in it rotates above the drone 1, that is, the drone 1 flips 180 degrees, and the rotors of the drone 1 are located below the rotor shafts (normally, the rotors are located above the rotor shafts, as shown in Figure 1 ), such a design will not leave an unpaintable dead corner at the upper end of the vertical wall, and the upper end of the vertical wall can also be painted;

[0046] Similarly, when the drone 1 rotated 180 degrees drives the overflow paint roller to roll down along the wall surface until it reaches the lower end of the vertical wall surface, in order to enable the overflow paint roller above the drone 1 to paint the lower end of the vertical wall surface, the drone 1 controls the drone 1 to rotate 180 degrees and resume Figure 1 the posture shown, so that the drone 1 can continue to descend to drive the overflow paint roller to paint the lower end of the vertical wall surface. Compared with the paint device for indoor decoration that can complete the paint operation by itself without relying on manual painting in the prior art, there are no dead corners that cannot be painted at the upper and lower ends of the vertical wall surface, and there is no need for manual supplementary painting, which saves time and effort and has good practicability.

[0047] Specifically, for the ground, during painting, Figure 1 the drone 1 shown descends under the control of the preset program in it to make the overflow paint roller close to the ground, and then the drone 1 moves horizontally to drive the overflow paint roller to roll close to the ground to complete the painting operation.

[0048] For the wall top surface, during painting, only Figure 1 the drone 1 shown needs to be rotated 180 degrees to make the overflow paint roller above the drone 1, and then the drone 1 ascends to make the overflow paint roller close to the wall top surface, and then the drone 1 moves horizontally to drive the overflow paint roller to roll close to the wall top surface to complete the painting operation.

[0049] In this embodiment, three control programs are preset in the drone 1, which are respectively applicable to the painting of vertical wall surfaces and inclined wall surfaces, the painting of the ground, and the painting of the wall top surface. In the early stage, the processor in the drone 1 obtains parameters such as the position coordinates, wall surface type, and wall surface size of the wall surface to be painted through the machine vision camera 18, and then runs the above programs to enable the drone 1 to drive the overflow paint roller to fly to the position of the wall surface to be painted by itself, and drive the overflow paint roller to roll close to the wall to complete the painting operation. It has a high degree of intelligence, less manual assistance work, good practicability, and effectively replaces the manual painting operation.

[0050] Next, a specific embodiment is used to illustrate the working principle of the paint device for indoor decoration of the present invention:

[0051] As Figure 6As shown, after the operator holds the remote controller 17 to control the drone 1 to take off, first make the drone 1 hover in the air, and then the operator holds the remote controller 17 to control the machine vision camera 18 to turn on and photograph the wall surface to be painted indoors. During the photographing process, control the drone 1 to rotate around the vertical axis and the horizontal axis to fully obtain parameter information such as the position coordinates, wall surface type, and wall surface size of the wall surface to be painted indoors. The above information is summarized in the processor of the drone 1 for analysis and processing, identifying the type, position, and size of each wall surface to be painted, and generating data such as the painting start position, painting path, and painting end position, and then sending them to the remote controller 17. The operator confirms whether the painting route is correct. When the operator holds the remote controller 17 to confirm that it is correct, after the drone 1 receives the confirmation signal, it starts the painting work according to the set painting route. For example, the drone 1 moves to the lower end of the nearest wall surface to be painted and makes the overflow paint roller close to the wall surface. Then, the controller in the drone 1 controls the infusion pump 15 to start. Next, the drone 1 moves upward to drive the overflow paint roller to roll close to the wall surface to complete the painting. When the drone 1 is about to reach the upper end of the wall surface, the drone 1 flips 180 degrees and then continues to move upward, avoiding the drone 1 touching the ceiling of the wall, and at the same time, the upper end of the wall can also be painted without dead corners.

[0052] In this embodiment, as Figure 1 shown, the overflow paint roller includes a liquid distribution pipe 10 and a soft brush paint roller cylinder 11. The liquid distribution pipe 10 is fixedly connected to the mounting rod 8, and the soft brush paint roller cylinder 11 is rotatably sleeved outside the liquid distribution pipe 10.

[0053] As Figure 5 [[ID=IO]]shown, the liquid distribution pipe 10 is provided with a liquid inlet hole 12 and a plurality of liquid outlet holes 13. The plurality of liquid outlet holes 13 are evenly distributed along the length direction of the liquid distribution pipe 10. One end of the infusion hose 14 is communicated with the liquid inlet hole 12. The paint is injected into the liquid distribution pipe 10 through the infusion hose 14, and then flows out from the liquid outlet holes 13. The paint flowing out from the liquid outlet holes 13 is absorbed by the soft brush paint roller cylinder 11. When the overflow paint roller full of paint rolls close to the wall surface, the overflow paint roller can evenly apply the paint on the wall surface.

[0054] }Preferably, as Figure 1 shown, the mounting rod 8 is fixedly connected to the middle part of the liquid distribution pipe 10. As Figure 4 and Figure 5 shown, the liquid inlet hole 12 is located in the middle part of the liquid distribution pipe 10. The soft brush paint roller cylinder 11 has two sections, located on both sides of the liquid inlet hole 12. With such a design, the problem of dead corners that are prone to occur at the wall inner corner and cannot be painted is solved. As for the area that is not painted between the two sections of the soft brush paint roller cylinder 11, it can be solved by repeated painting.

[0055] In this embodiment, as Figure 1 、 Figure 2 andFigure 6 As shown, the middle portion of the infusion hose 14 is fixedly connected to the mounting rod 8. This design can prevent the infusion hose 14 from touching the wall and damaging the newly painted paint layer.

[0056] Furthermore, in this embodiment, Figures 1 - 3 、 Figure 6 、 Figure 8 and Figure 9 As shown, a horizontal plate 2 is fixedly provided at the bottom of the drone 1, and vertical plates 19 are fixedly provided at both ends of the horizontal plate 2. A screw rod 4 is installed through the two vertical plates 19, and one end of the screw rod 4 is transmission-connected to the motor 3. The motor 3 is fixedly connected to the vertical plate 19. After the motor 3 is started, it can drive the screw rod 4 to rotate; the mounting rod 8 is spirally sleeved on the screw rod 4 and is slidingly connected to the horizontal plate 2. With this design, the mounting rod 8 can be driven to move along the length direction of the screw rod 4 by controlling the forward and reverse rotation of the motor 3 to adjust the position of the overflow paint roller relative to the drone 1. Specifically, the rotation of the screw rod 4 drives the mounting rod 8 to move horizontally left and right, and the stroke L1 is shown as follows Figure 9 As shown, when the mounting rod 8 moves to Figure 9 When the left end of the stroke L1 is reached, the overflow paint roller can paint the wall at the corner on the left side of the drone 1. Figure 9 When it reaches the right end of the stroke L1, the overflow paint roller can paint the wall at the corner on the right side of the drone 1. This design solves the problem that the overflow paint roller cannot paint the wall at the corner due to the length limitation of the overflow paint roller and the inability of the drone 1 to continue to move horizontally at the corner, ensuring that the wall around the corner can also be painted, without dead corners that cannot be painted, and has good practicality.

[0057] In this embodiment, during the movement of the mounting rod 8 along the screw rod 4, the center of gravity of the entire interior decoration paint device is constantly changing. To ensure the balance of the drone 1, the rotation speed of the corresponding rotor of the drone 1 also needs to be adjusted synchronously. Therefore, it is necessary to constantly monitor the position of the mounting rod 8 on the screw rod 4. Figure 3 As shown, a distance measuring device 5 is fixedly provided on the vertical plate 19 or the mounting rod 8 for detecting the distance between the mounting rod 8 and the vertical plate 19. The monitoring data is transmitted to the processor of the UAV 1 in real time, and the processor adjusts the rotation speed of each rotor in real time according to the detection data to ensure the stability of the UAV 1 in the air.

[0058] Furthermore, in this embodiment, Figures 1 - 2 、 Figure 6 、 Figure 8 and Figure 9 As shown, the mounting rod 8 is in an eight-shaped shape, with the overflow paint roller installed at one end and the screw propeller 9 installed at the other end. The center of gravity of the mounting rod 8 after the overflow paint roller and the screw propeller 9 are installed is located at Figure 8On the vertical line directly below the lead screw 4 shown, the top end of the mounting rod 8 is spirally sleeved on the lead screw 4 and is linearly slidably connected to the cross plate 2, that is, the top end of the mounting rod 8 is in linear contact with the cross plate 2. With this design, the mounting rod 8 can rotate around the lead screw 4, solving the problem that the overflow paint roller suddenly presses against the wall surface and causing the drone 1 to lose stability. The design of the mounting rod 8 in an eight - shape also makes the center of gravity of the mounting rod 8 located directly below the lead screw. During the process of the lead screw 4 rotating to drive the mounting rod 8 to move, the mounting rod 8 will not rotate around the lead screw 4.

[0059] In this embodiment, as Figure 6 and Figure 8 shown, the screw propeller 9 includes a propeller and a power device for driving the propeller to rotate. The rotation center line of the propeller is horizontal and together with the mounting rod 8 defines an isosceles triangle. With this design, the screw propeller 9 can replace the drone 1 to push the overflow paint roller against the wall surface, avoiding the problem that the drone 1 drives the overflow paint roller to move and suddenly press against the wall surface, causing the drone 1 to lose stability. Moreover, the screw propeller 9 replacing the drone 1 to push the overflow paint roller against the wall surface also facilitates controlling the pressure of the overflow paint roller on the wall surface, helping to keep the pressure of the overflow paint roller on the wall surface constant. For example, when Figure 8 there is a vertical wall surface on the right side of the overflow paint roller in, the drone 1 drives the overflow paint roller close to the vertical wall surface but does not contact the vertical wall surface. After the screw propeller 9 is started, it has a right - ward thrust F2 on the mounting rod 8. The thrust F2 makes the overflow paint roller press against the wall surface. The wall surface has a left - ward supporting force F1 on the overflow paint roller. These two forces are equal in magnitude and opposite in direction. By adjusting the rotation speed of the propeller of the screw propeller 9, the pressure of the overflow paint roller on the wall surface can be adjusted, which is convenient to control and helps to keep the pressure of the overflow paint roller on the wall surface constant. During the whole process, the drone 1 only provides buoyancy for the mounting rod 8 to be suspended on the lead screw 4 and for the mounting rod 8 to rotate around the lead screw 4.

[0060] In this embodiment, as Figure and ​ shown, on the lower surface of the cross plate 2 on both sides of the lead screw 4, there are provided limiting strips 7 parallel to the lead screw 4. The two limiting strips 7 are slidably connected to the mounting rod 8. With this design, it helps the mounting rod 8 to move smoothly on the lead screw 4. The material of the limiting strip 7 is porous rubber. With this design, it does not affect the rotation of the mounting rod 8 around the lead screw 4. When the mounting rod 8 rotates around the lead screw 4, it can squeeze the limiting strip 7.

[0061] In this embodiment, as ​ shown, a distance measuring device two 6 is fixed on the mounting rod 8, which is used to detect the vertical distance between the mounting rod 8 and the cross plate 2. When the mounting rod 8 rotates around the lead screw 4, the distance changes. By detecting whether the distance changes, it can be judged whether the mounting rod 8 rotates around the lead screw 4. And the center of gravity of the mounting rod 8 is in ​On the vertical line shown, only when the overflow paint roller contacts the wall surface, the mounting rod 8 will rotate around the lead screw 4. Therefore, by detecting whether the distance changes through the second distance measuring device 6, it can be determined whether the overflow paint roller contacts the wall surface, eliminating the trouble of manually judging whether the overflow paint roller contacts the wall surface. After detecting that the overflow paint roller contacts the wall surface, the drone 1 can hover, and the overflow paint roller is pushed by the screw propeller 9 to press against the vertical or inclined wall surface; for the ground and the top surface of the wall, the pressure magnitude between the overflow paint roller and the wall surface can be judged according to the change amount of the distance detected by the second distance measuring device 6, and then the rotation speed of the corresponding rotor of the drone 1 can be adjusted accordingly, so that after the overflow paint roller contacts and adheres to the ground or the top surface of the wall, the drone 1 can restore balance in the shortest time.

[0062] In this embodiment, preferably, the drone 1 adopts a multi-rotor drone to facilitate the drone 1 to control the lifting, front-back, and left-right movement of the overflow paint roller. Specifically, there are at least four rotor shafts of the drone 1; two of the rotor shafts are in the same vertical plane as the lead screw 4. With this design, it is convenient for the drone 1 to restore balance in the shortest time when the mounting rod 8 moves along the lead screw 4; another two rotor shafts are in another same vertical plane as the mounting rod 8 in an eight-character shape. With this design, it is convenient for the drone 1 to restore balance in the shortest time after the overflow paint roller contacts and adheres to the top surface of the wall or the ground.

[0063] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
