Through the cooperation of multiple groups of card blocks 15 and multiple groups of card slots 13, the user can easily assemble or disassemble the roller brush 2, the bearing 3 and the discharge barrel 14. The detachable roller brush 2 can be easily disassembled for cleaning to remove the hardened paint residue, which can ensure that the roller brush can work normally when used next time and extend the service life of the roller brush 2. If the roller brush 2 is severely worn or damaged due to long-term use, the detachable design allows the user to easily replace the new roller brush 2 without replacing the entire painting device, saving maintenance costs.

[0025] like Figures 2 to 5As shown, the other end of the discharge barrel 14 is clamped with a connecting cover 1, one end of the connecting cover 1 is clamped with a suction nozzle 18, and one end of the suction nozzle 18 is clamped with a sealing cover 6 to prevent the paint from flowing out of the suction nozzle 18. The other end of the connecting cover 1 is clamped with a paint barrel 10, and a circular baffle 7 is set at one end of the connecting cover 1. A circular chute 11 is opened at one end of the paint barrel 10, and an opening 19 is opened on one side of the circular baffle 7 and the circular chute 11. A limit block 8 is clamped on the surface of the circular baffle 7, and two groups of limit grooves 9 are opened on the surface of the circular chute 11. The limit block 8 is clamped on one group of limit grooves. In the groove 9, one end of the circular baffle 7 is clamped in the circular slide groove 11, and the other side of the circular baffle 7 is clamped in the connecting cover 1. The user can rotate the circular baffle 7. When the limit block 8 is engaged with one group of limit grooves 9, the two groups of openings 19 overlap, and the paint can flow out from the openings 19. When the limit block 8 is engaged with the other group of limit grooves 9, the circular baffle 7 will close the openings 19 at the circular slide groove 11. Multiple groups of discharge holes 12 are arranged between every two groups of clamping grooves 13. A cavity 16 is opened between the multiple groups of discharge holes 12 and the discharge barrel 14, and the cavity 16 is communicated with the two groups of openings 19.

[0026] The paint cylinder 10 is sleeved in the discharge cylinder 14. The paint cylinder 10 is used to store the paint for wall painting. A piston 17 is sleeved in the paint cylinder 10. A push rod 4 is clamped at one end of the piston 17. One end of the push rod 4 passes through the paint cylinder 10 and the discharge cylinder 14. The paint cylinder 10 is designed in the form of a syringe. Before use, the circular baffle 7 is rotated to close the opening 19 at the paint cylinder 10. By pushing the push rod 4 to one end away from the paint cylinder 10, the paint can be sucked into the paint cylinder 10. After the paint is filled, the circular baffle 7 is rotated to open the opening. Mouth 19, and then the paint cylinder 10 is loaded into the discharge cylinder 14, the discharge cylinder 14 and the paint cylinder 10 are fixedly connected through the connecting cover 1, and the push rod 4 is pushed into the paint cylinder 10, and the piston 17 will squeeze the paint in the cylinder, so that it flows into the cavity 16 and flows out from the multiple groups of discharge holes 12, so as to be adsorbed on the roller brush 2, and the brushing work can be carried out. This way of adsorbing paint will not cause the paint to splash out, reducing the waste of paint, and at the same time making the brushing process cleaner and safer, which is conducive to improving the uniformity and quality of brushing.

[0027] The specific usage and function of this embodiment are as follows:

[0028] After the paint is filled, the sealing cover 6 is closed, and the user can rotate the circular baffle 7 to open the opening 19 at one end of the paint barrel 10, and then fix the paint barrel 10 with the discharge barrel 14 through the connecting cover 1. Subsequently, the user can push the push rod 4 to move it into the paint barrel 10, and the piston 17 at one end thereof will squeeze the paint in the barrel, and the paint will flow out from the opening 19 into the cavity 16, and then flow out from the multiple groups of discharge holes 12 and be adsorbed on the roller brush 2. After seeing the paint evenly emerging from the surface of the roller brush 2, the push rod 4 can be stopped from being pushed. The user can perform the wall painting work by pushing the brush rod 5. After the painting work is completed, the roller brush 2 can be removed from the discharge barrel 14, which is convenient for cleaning and is conducive to extending the service life of the roller brush 2.

[0029] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
