Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coating device with a paint coating roller.

Conventionally, paint has been fed into the paint application roller through a paint introduction pipe, but no suitable method has been developed from a practical standpoint.

For example, in Japanese Utility Model Application Publication No. 48-62339, a cylindrical body made of sponge, nonwoven fabric, or other paint permeable material is fitted around the outer periphery of a pressure-filled pipe, and a brush is formed on the periphery of the cylindrical body. Although a coating tool is described, a cylindrical body made of a sponge, non-woven fabric, or other paint-transmitting material is interposed between the brush and the paint-transmitting pipe, and the structure is not only complicated, but also the part of the paint-transmitting material. The disadvantage was that it took too much time and effort to clean it after use and make it suitable for reuse.

Further, for example, in Japanese Utility Model Application Publication No. 51-52051, a roller is interposed between a conduit and a cover, and a supply hole is provided in the roller part, and the supply hole is moved from the inner circumference of the roller to the outer circumference. It is described that the paint penetrates in the radial direction up to the position of the roller, but in order to sufficiently supply the paint to the outer peripheral surface of the roller, the force for pumping the paint must be particularly increased.
Alternatively, there is a drawback that the paint cannot be used unless some measure is taken to supply the paint, such as enlarging the diameter of the supply hole or increasing the number of the supply holes.

The present invention aims to eliminate the above-mentioned drawbacks.

Next, the specific configuration for achieving the above purpose will be explained according to the drawings.
, a grip tube 7 for supporting the roller 9, and a hose 4 connected to the grip tube 7 via a chuck tube.
and a paint container 3 containing a power battery 1 and a pump 2 connected to the other end of the hose 4 via a chuck tube 6, and a motor operating switch 8 is provided at the grip tube. The hose 4 is provided with an electric wire connected to the switch 8, and the electric wire 5 is connected to the pump 2 in the paint container 3.
A roller internal structure 11 is disposed at the central axis of the coating roller 9, and a roller external structure 12 is disposed around the outer periphery of the roller internal structure 11. A paint outflow portion 10 is arranged in a radial direction from the paint outflow portion 1.
This is a painting device with a paint application roller, which has a tip end portion of the roller 0 opened at an intermediate position of the roller external structure 12.

Next, to describe the effects of the above configuration, the paint application roller, hose, and paint container are connected, so the user can wrap the paint container around the user's body with a belt or the like and take the roller with his or her hand. This has the effect of allowing you to use your other hand, and it is effective in ensuring sufficient safety compared to the paint application process where you hold a brush in one hand and a paint container in the other hand. In addition, chucks were provided at both ends of the hose, and through the chucks, one was connected to the paint container and the other to the roller support gripping tube, so when not in use, each member was removed from the other, and when used, each After assembling the parts and performing the painting work, each part can be removed at the chuck part and each part can be washed individually. Furthermore, by operating the motor operating switch provided on the grip, the pump in the paint container can be driven or stopped. Further, a roller internal structure is disposed at a central axis portion of the coating roller, a roller external structure is disposed on the outer periphery of the coating roller, and a paint outflow portion is disposed in a radial direction from the roller internal structure, Since the tip of the paint outflow part is opened at the intermediate position of the roller external structure, when the paint is sent out, the paint coming out from the tip of the paint outflow part is spread from the intermediate position of the roller external structure to other parts. Therefore, when the paint reaches the outer circumferential position of the roller external structure, it can be delivered evenly to that outer circumferential position, ensuring that the paint is evenly and reliably delivered to the coating surface of the object to be painted. And it has an effect that can be easily achieved.
