[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] Please see Figure 1-4 This utility model provides a technical solution: a decorative paint painting device, including a mounting shell 1, a mounting groove 11 on one side of the mounting shell 1, a brush roller 12 rotatably mounted inside the mounting groove 11, and a receiving plate 13 fixedly connected to the bottom of the mounting groove 11 near the opening; during painting, the brush roller 12 contacts the painting area, and during the painting process, the receiving plate 13 can collect the fallen paint into the mounting groove 11 for subsequent unified treatment.

[0032] A connecting block 2 is fixedly connected to one side of the mounting shell 1. A transfer tank 3 is fixedly connected to the side wall of the connecting block 2. Two first connecting pipes 31 are fixedly connected to the outer periphery of the transfer tank 3. The ends of the two first connecting pipes 31 are connected to first conveying pipes 32. A spray frame 39 is fixedly connected to the top of the inner wall of the mounting groove 11. The first conveying pipe 32 passes through the mounting shell 1 and is connected to the spray frame 39. When painting, the transfer tank 3 and the components work together to convey the paint to the first connecting pipes 31. The paint enters the first conveying pipe 32 through the first connecting pipes 31 and is then conveyed to the spray frame 39 by the first conveying pipe 32. Several nozzles are installed on the spray frame 39, which sprays the paint onto the outer periphery of the brush roller 12. When the brush roller 12 rotates to paint, the spray frame 39 simultaneously sprays the paint onto the outer periphery of the brush roller 12. The cooperation of the components allows for dynamic spraying of paint according to the rotation speed of the brush roller 12, ensuring that the paint adhesion on the surface of the brush roller 12 is always uniform.

[0033] Example 2:

[0034] Please see Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The bottom surface of the mounting groove 11 is inclined and the mounting groove 11 is lower away from the opening. Excess paint enters the interior of the mounting groove 11 and flows into the interior of the mounting groove 11.

[0035] A rotating rod 41 is rotatably installed inside the mounting shell 1 and the connecting block 2. A stepper motor 4 is fixedly connected to the side wall of the connecting block 2. The outer periphery of the rotating rod 41 is fixedly connected to the brush roller 12. The rotating rod 41 passes through the connecting block 2 and is fixedly connected to the shaft of the stepper motor 4. When the stepper motor 4 is turned on, the stepper motor 4 drives the rotating rod 41 to rotate, and the rotation of the rotating rod 41 drives the brush roller 12 to rotate.

[0036] Two second connecting pipes 33 are connected to the outer periphery of the transfer tank 3 away from the first connecting pipe 31. The ends of the two second connecting pipes 33 are connected to the second conveying pipes 34. A storage tank 35 is provided at the bottom of the mounting shell 1. The bottom end of the second conveying pipes 34 is connected to the storage tank 35. The paint moves from the storage tank 35 into the second conveying pipes 34, then moves through the second conveying pipes 34 into the second connecting pipes 33, and finally enters the transfer tank 3 through the second connecting pipes 33.

[0037] A second check valve 37 is provided on the first connecting pipe 31, and a first check valve 36 is provided on the second connecting pipe 33. The first check valve 36 and the second check valve 37, which are located on the same horizontal plane, have opposite opening and closing states. When conveying paint, the opening and closing states of the first check valve 36 and the second check valve 37 are always in opposite states. When the paint is output from the first connecting pipe 31 at the top, the first check valve 36 at the bottom opens and the second check valve 37 at the bottom closes. The paint enters the transfer tank 3 from the second connecting pipe 33 at the bottom. The same applies when the paint is output from the first connecting pipe 31 at the bottom.

[0038] The connecting block 2 is equipped with a gear 42 and a crown gear 43. The gear 42 is fixedly sleeved on the outer circumference of the rotating rod 41. A cylindrical rod 44 is rotatably mounted on one side of the connecting block 2. The end of the cylindrical rod 44 passes through the connecting block 2 and is fixedly connected to the crown gear 43. The gear 42 and the crown gear 43 are meshed together. When the rotating rod 41 rotates, it drives the gear 42 to rotate. The rotation of the gear 42 drives the crown gear 43 to rotate. The rotation of the crown gear 43 drives the rotating rod 41 to rotate. The rotation of the rotating rod 41 drives the cylindrical rod 44 to rotate.

[0039] A sliding rod 47 is slidably mounted on the top of the transfer barrel 3, and a piston 38 is slidably mounted inside the transfer barrel 3. The bottom end of the sliding rod 47 passes through the transfer barrel 3 and is fixedly connected to the top surface of the piston 38. An elliptical frame 46 is fixedly connected to the top end of the sliding rod 47. A connecting rod 45 is fixedly connected to one end of a cylindrical rod 44, and one end of the connecting rod 45 is rotatably connected to the elliptical frame 46. When the cylindrical rod 44 is rotated, the cylindrical rod 44 rotates, causing the connecting rod 45 to rotate. One end of the connecting rod 45 moves left and right inside the elliptical frame 46, while simultaneously causing the elliptical frame 46 to move up and down reciprocally. The up and down reciprocating movement of the elliptical frame 46 causes the sliding rod 47 to move back and forth, and the up and down reciprocating movement of the sliding rod 47 causes the piston 38 to move up and down reciprocally.

[0040] A handle 21 is fixedly connected to the bottom surface of the connecting block 2; the user holds the handle 21 to perform painting work.

[0041] The bottom surface of the mounting groove 11 is connected to a receiving pipe 14; the receiving pipe 14 helps to collect excess paint, and the end of the receiving pipe 14 is connected to the waste collection point.

[0042] The elliptical bracket 46 is positioned perpendicular to the sliding rod 47, thus facilitating the normal operation of the piston 38.

[0043] Example 3:

[0044] Please see Figure 1-4This is the third embodiment of the present invention, based on the above two embodiments. In use, paint is added to the storage bucket 35, and then one side of the brush roller 12 of the device is placed against the wall. The user holds the end of the handle 21 and turns on the stepper motor 4. The stepper motor 4 rotates, driving the rotating rod 41 to rotate, which in turn drives the brush roller 12 to rotate. The direction of rotation of the stepper motor 4 is adjusted according to whether painting is upward or downward. Simultaneously, the rotation of the rotating rod 41 drives the gear 42 to rotate, which in turn drives the crown gear 43 to rotate, which in turn drives the rotating rod 41 to rotate, which in turn drives the cylindrical rod 44 to rotate, which in turn drives the connecting... When rod 45 rotates, one end of connecting rod 45 moves left and right inside the elliptical frame 46, simultaneously causing the elliptical frame 46 to move up and down reciprocally. The up and down reciprocating movement of the elliptical frame 46 causes the sliding rod 47 to move back and forth, which in turn causes the piston 38 to move up and down reciprocally. The cooperation of piston 38, first one-way valve 36, second one-way valve 37, and transfer tank 3 extracts the paint from the storage tank 35. The paint enters the second connecting pipe 33 along the second conveying pipe 34. When piston 38 moves upward, the first one-way valve 36 at the top closes, and the second one-way valve 37 at the top opens, allowing the paint to be output from the first connecting pipe 31 at the top. The same logic applies when moving downward. The paint passes through the first connecting pipe 31... A connecting pipe 31 moves towards the first conveying pipe 32, and through the first conveying pipe 32 moves the spray frame 39. The spray frame 39 is equipped with several nozzles, and the paint is sprayed out through the nozzles, evenly spraying the paint onto the outer periphery of the brush roller 12. This eliminates the need for frequent dipping of paint by the user, thus improving painting efficiency. Excess paint sprayed from the second connecting pipe 33 falls into the mounting groove 11. Due to the inclined design of the mounting groove 11, the paint moves to the side away from the opening of the mounting groove 11. During painting, excess paint enters the mounting groove 11 along the receiving plate 13. During painting, the brush roller 12 is in contact with the wall, and the receiving plate 13 is at a certain distance from the wall. Excess paint falls through the receiving pipe 14 into a designated area. Collection point; In this utility model, during painting, the coordination of the transfer bucket 3, the spray frame 39, and the components allows for dynamic spraying of paint according to the rotation speed of the brush roller 12, ensuring that the paint adhesion on the surface of the brush roller 12 is always uniform, avoiding "thick coating" caused by uneven force when manually applying paint, thus improving the smoothness of the painting. Moreover, the rotation of the brush roller 12 and the spraying of paint by the spray frame 39 are synchronized, eliminating the need for frequent stops to replenish paint, thereby improving work efficiency. In this utility model, paint dripping during the painting process is collected into the installation groove 11 by the receiving plate 13, preventing paint from dripping onto the ground. At the same time, it enables real-time recycling of excess paint, and waste is collected and uniformly processed through the collection pipe 14, improving the utilization rate of paint.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
