Detailed ways

The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Figures 1-6, the wall painting device of the present invention, which is convenient for adjusting the amount of painting, is mainly composed of a fixing frame 1, an air intake tank 5 and a paint storage rod 2; the lower end of the fixing frame 1 is used as the main body; A fixed rod 12 and a paint storage rod 2 sleeved on the fixed rod 12 are provided, and the interior of the paint storage rod 2 is hollowed out for storing paint. After filling the paint, it is covered with the end of the paint storage rod 2 through a sealing cover 21; The two ends of the fixing frame 1 are respectively provided with a ring-shaped bracket 9 and a cylindrical brush 4 that can be rolled on the wall, and the middle of the bracket 9 is provided with a bracket 9 that can fit on the inner wall of the annular bracket 9 and slide up and down. The air intake tank 5; the side wall of the air intake tank 5 and the bracket 9 are respectively provided with a rack 93, a worm 91 and a worm wheel 92, the worm wheel 92 is located in the middle of the rack 93 and the worm 91, and the worm wheel 92 and the rack 93 are respectively Meshing with the worm 91, the worm wheel 92 can be self-locking after adjustment.

When in use, first unscrew the sealing cover 21 at the rear end of the paint storage rod 2, then pour the paint liquid into the paint storage rod 2, and cover the sealing cover 21; then, adjust the worm 91 according to the amount of paint on the wall. At this moment, the worm 91 drives the worm wheel 92 to rotate on the bracket 9, and at the same time the worm wheel 92 drives the gear to slide at the front end of the bracket 9; The eccentric convex column 41 on the end face rotates eccentrically with the rotation of the brush 4, and drives the compressed air piston 61 to move up and down in the intake tank 5 through the connecting rod 6, and presses the air in the compressed air cavity 51 at the lower end of the compressed air piston 61 into the intake pipe 8. middle;

During this process, when the eccentric protruding post 41 rotates to the upper end of the end face of the brush 4, the connecting rod 6 drives the compressed air piston 61 to move upward in the intake tank 5, and the gas enters the compressed air chamber 51 from the intake valve 7. When the eccentric post 41 rotates to the lower end of the end face of the brush 4, the connecting rod 6 drives the compressed air piston 61 to move down in the air intake tank 5, and the air enters the paint storage rod 2 from the air outlet valve 71 through the air intake pipe 8. The brush head faces upwards in the conventional use, therefore, the gas gathers in the upper part of the paint storage rod 2, and the paint in the lower part is pressed into the paint inlet pipe 3 to the paint inlet chamber 43, so as to realize the output of the paint;

As the brush 4 continuously rolls on the wall surface, a reciprocating compressed air movement is formed in the air inlet tank 5; The paint hole 42 continuously flows out and paints onto the wall.

Further, due to the compressibility of the gas, the more gas there is in the intake tank 5, the larger the compressible space. Therefore, when there is a lot of gas in the intake tank 5, the compression piston 61 is pressed down, and the gas is under pressure. A large degree of gas compression occurs, which reduces the pressure and greatly reduces the volume of the original gas, thereby reducing the amount of paint discharged; on the contrary, when the gas in the intake tank 5 is less, the compressor piston 61 presses down , the gas is compressed to a small extent by the pressure, the pressure is not reduced, and the volume of the original gas volume is hardly reduced, so as to maintain a large paint discharge; the above can be manually rotated by the worm 91 to drive the worm wheel 92 to drive the teeth The bar 93 changes the distance between the bottom of the intake tank 5 and the compressed air piston 61, and changes the space volume of the compressed air cavity 51, thereby changing the amount of gas flowing out of the air outlet valve.

The specific embodiments described above further describe the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above descriptions are only specific embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
