The roller brush 420 is coupled on the outer circumference of the roller body 410.

Referring to the operation of the paint roller 10 according to an embodiment of the present invention made of a configuration as described above as follows.

First, after injecting paint liquid into the container 100 and storing it, the container 100 is screwed with the lower end of the housing 700. At this time, the pump structure 200 is coupled to the inlet of the receiving container (100).

In addition, the handle 500 is coupled to the support pipe 300 is equipped with a roller 400.

When holding the handle 500 in the state as described above by pressing the switch 530, the infrared signal is passed through the support rod 600 to the circuit portion 720 inside the housing 700 is transferred to the motor 730 As the pressing unit 750 is pressed by the rotational operation, the piston 240 moves downward while compressing the spring 235.

As the piston 240 descends, the lifting rod 250 and the pressure member 260 coupled thereto are also moved downward.

As the pressing member 260 moves downward, the accommodating chamber 223 inside the cylinder 220 is compressed while the volume is reduced, and the paint liquid filled in the accommodating chamber 223 during the compression process is introduced into the elevating rod 250. After entering the fluid passage 251 of the lifting rod 250 through the ball 252 is transferred to the support pipe 300 through the fluid passage 251.

In the compression process, the opening and closing ball body 270 is closed to close the inlet 222 of the cylinder 220 by the compression force of the cylinder 220 is operated to enable compression, the lifting rod 250 is fully lowered In the state, the cylinder 220 is further tightly sealed by being pressed by the lower recess groove 253 of the lifting rod 250.

As described above, the paint liquid pumped by the compression of the cylinder 220 and transferred to the support tube 300 is discharged through the discharge hole 310, and the discharged paint liquid discharges the outlet 411 of the roller body 410. Is discharged through the roller brush 420 is to be absorbed.

While the switch 530 is pressed, the pressing part 750 is repeatedly pressed to continuously pump the paint liquid to the roller brush 420. Subsequently, when the force that presses the switch 530 is removed, the operation of the pressing unit 750 is stopped to stop the pumping movement. As a result, the storage chamber 223 inside the cylinder 220 expands in volume. The suction force is generated by the pressure reduction according to this, and the opening and closing ball body 270 is raised upward to open the suction port 222, and at the same time a new amount of paint liquid received through the suction port 222 is accommodated. Inflow from the container 100 into the storage chamber 223 is filled.

As described above, the paint roller provided with the paint supply apparatus according to the present invention has been described, but the technical scope of the present invention is not limited to the contents described in the above-described embodiments, and is modified by those skilled in the art.
