[0038] The inside of the barrel 1 is divided into a front paint cavity 103 and a rear balance cavity 104 by the piston assembly 3. When the piston assembly 3 extends out of the barrel 1, the extension end of the piston assembly 3 is controlled to move forward and backward to change the size of the space inside the paint cavity 103 and the balance cavity 104, realizing the switching of the forward pushing painting and the rear pulling pressure increasing functions.

[0040] The atmosphere pipe 105 is a one-way flow structure from outside to inside, and the feeding pipe 107 is also a one-way flow structure from outside to inside. When the piston assembly 3 is pushed forward, the atmosphere pipe 105 is opened to supplement the gas in the balance cavity 104, the feeding pipe 107 and the balance pipe 106 are closed, the piston assembly 3 extrudes the paint in the paint cavity 103, and the paint seeps out of the brush head assembly 2 to the outer wall screw hole.

[0041] When the piston assembly 3 is pulled backward, the atmosphere pipe 105 is closed, the balance pipe 106 and the feeding pipe 107 are opened, the piston assembly 3 extrudes the gas in the balance cavity 104, the gas in the balance cavity 104 enters the paint supply assembly 4 through the balance pipe 106, the pressure in the paint supply assembly 4 increases, the paint in the paint supply assembly 4 is pressed to the paint cavity 103 through the feeding pipe 107 to supplement the paint in the paint cavity 103, and the paint cavity 103 is always in a full state.

[0042] The brush head assembly 2 and the piston assembly 3 are arranged on the barrel 1 in the axial direction, and the brush head assembly 2 is connected with the piston assembly 3 through the linkage assembly 5. Therefore, when the piston assembly 3 is rotated, the brush head assembly 2 is rotated synchronously through the linkage assembly 5, and the uniform painting of the paint is realized by the rotating brush head assembly 2.

[0043] The barrel 1 comprises a barrel ring 101 and a cover 102. The barrel ring 101 is a cylindrical structure, and the brush head assembly 2 is arranged at the front end opening of the barrel ring 101. The brush head assembly 2 blocks the front end opening, so that the paint can only seep out of the brush head assembly 2. The cover 102 is a disc structure and is welded at the rear end opening of the barrel ring 101 to completely block the rear end opening. The brush head assembly 2, the barrel ring 101 and the piston assembly 3 (piston 301) form a paint cavity 103, and the piston assembly 3 (piston 301), the barrel ring 101 and the cover 102 form a balance cavity 104.

The paint in the paint cavity 103 flows out through the uniformly distributed seepage holes of the seepage hole plate 202, and then is adsorbed on the sponge body 203. During the brushing operation, the sponge body 203 is in contact with the outer wall to realize pressure discharge and brush the paint on the outer wall.

[0046] The piston assembly 3 comprises a piston 301, a sealing ring 302, a push rod 303 and a push handle 304. The piston 301 is a cylindrical structure, and the outer wall (periphery) of the piston 301 is provided with the sealing ring 302 in contact with the inner wall of the barrel 1. The piston 301 and the sealing ring 302 absolutely separate the front and rear cavities in the barrel 1.

[0047] The rear end center of the piston 301 is fixedly connected with the front end of the push rod 303, the push rod 303 extends out of the cover 102 at the rear end of the barrel 1, and the rear end of the push rod 303 is fixedly connected with the push handle 304. The push handle 304 facilitates the operation of the piston 301 and the push rod 303 to control the forward and backward movement or rotation thereof.

[0048] The paint supply assembly 4 comprises a paint bucket 401 for storing paint, and the paint bucket 401 is provided with an air inlet pipe 402 and a paint outlet pipe 403. The air inlet pipe 402 is communicated with the balance pipe 106 through a hose to send the gas in the balance chamber 104 into the paint bucket 401 to increase the pressure inside the paint bucket 401. The paint outlet pipe 403 is communicated with the feed pipe 107 through a hose, and the paint outlet pipe 403 extends to the bottom of the paint bucket 401. Therefore, the paint in the paint bucket 401 can be pressed to the paint chamber 103 after the pressure inside the paint bucket 401 is increased.

[0049] The brush ring 201 of the brush head assembly 2 is arranged on the barrel ring 101 in axial rotation, the piston 301 of the piston assembly 3 is also arranged on the barrel ring 101 in axial rotation, and the push rod 303 of the piston assembly 3 is arranged on the cover 102 in axial rotation. The linkage assembly 5 comprises a connecting rod 501, a cross seat 502, a cross rod 503 and a snap ring 504.

[0050] Preferably, the snap ring 504 is provided with a cross-shaped groove in the center, and the push rod 303 is provided with a cross-shaped edge matched with the cross-shaped groove. The snap ring 504 is sleeved on the push rod 303. When the push rod 303 moves forward and backward, the connecting rod 501 will not move forward and backward, but when the push rod 303 rotates in the axial direction, the snap ring 504 and the connecting rod 501 will rotate synchronously, and the brush ring 201 and the sponge body 203 will also rotate to ensure uniform brushing effect.

[0051] The method further comprises the following steps: first, clean the screw hole of the outer wall.

[0052] Secondly, align the brush head assembly 2 with the screw hole of the outer wall, and ensure that the sponge body 203 is in contact with the outer wall. Push the piston 301 of the piston assembly 3 forward through the push handle 304. External gas enters the balance chamber 104 to balance the pressure through the atmosphere pipe 105. The piston 301 of the piston assembly 3 extrudes the paint in the paint chamber 103, and the paint seeps out of the paint seepage hole plate 202 and the sponge body 203 of the brush head assembly 2 to the screw hole of the outer wall.

[0053] At the same time, operate the push handle 304 to make the push rod 303 of the piston assembly 3 rotate in the axial direction of the barrel 1.

[0055] Meanwhile, the material permeation hole plate 202 can also be designed as an inward and outward one-way flow structure, so that when the piston 301 is pulled back, the paint cavity 103 can also form a negative pressure environment, optimizing the feeding effect.

[0056] Fourth step, repeat the first step to the third step until all the screw holes are painted.
