DETAILED DESCRIPTION

[0034] The following non-limiting examples are provided to illustrate the present application.

[0035] Example 1

[0036] refer to Figure 1 to Figure 7 As shown, a waterproof brushing method for external wall screw holes is used. The method uses an external wall screw hole waterproof brushing device. Before brushing, the brushing device needs to be installed and the paint cavity 103 is filled with paint. The device includes a barrel 1, a brush head assembly 2, a piston assembly 3, a paint supply assembly 4 and a linkage assembly 5.

[0037] The cylinder 1 is a structure with an open front end and a closed rear end, which is used for both containing paint and providing air pressure. A brush head assembly 2 is provided at the front opening of the cylinder 1. The brush head assembly 2 is in direct contact with the outer wall and can penetrate the paint in the cylinder 1 to the outer wall to complete the function of brushing.

[0038] The interior of the cylinder 1 is divided into a front paint chamber 103 and a rear balance chamber 104 by the piston assembly 3. When the piston assembly 3 extends out of the cylinder 1, the piston assembly 3 is driven to move forward and backward by controlling the extended end of the piston assembly 3 to change the size of the internal space of the paint chamber 103 and the balance chamber 104, thereby realizing the switching of the forward push painting and rear pull boosting functions.

[0039] The paint chamber 103 is connected to the brush head assembly 2 , a feed pipe 107 connected to the paint chamber 103 is provided on the barrel 1 , an atmospheric pipe 105 and a balance pipe 106 connected to the balance chamber 104 are provided on the barrel 1 , and both the feed pipe 107 and the balance pipe 106 are connected to the paint supply assembly 4 .

[0040] The atmospheric pipe 105 is a one-way flow structure from outside to inside, and the feed pipe 107 is also a one-way flow structure from outside to inside. When the piston assembly 3 is pushed forward, the atmospheric pipe 105 opens to replenish air into the balance chamber 104, the feed pipe 107 and the balance pipe 106 are closed, and the piston assembly 3 squeezes the paint in the paint chamber 103, and the paint seeps out from the brush head assembly 2 to the screw hole of the outer wall.

[0041] When the piston assembly 3 is pulled backward, the atmospheric pipe 105 is closed, the balancing pipe 106 and the feeding pipe 107 are opened, the piston assembly 3 squeezes the gas in the balancing chamber 104, and the gas in the balancing chamber 104 enters the paint supply assembly 4 through the balancing pipe 106. The pressure in the paint supply assembly 4 increases, and the paint in the paint supply assembly 4 is pressed into the paint chamber 103 through the feeding pipe 107, so as to replenish the paint for the paint chamber 103 and keep the paint chamber 103 always full.

[0042] The brush head assembly 2 and the piston assembly 3 are axially rotatably arranged on the cylinder 1. The brush head assembly 2 is connected to the piston assembly 3 through the linkage assembly 5. When the piston assembly 3 is rotated, the brush head assembly 2 is driven to rotate synchronously through the linkage assembly 5, and the rotating brush head assembly 2 is used to achieve uniform brushing of the paint.

[0043] The cylinder body 1 includes a cylinder ring 101 and a cover 102. The cylinder ring 101 is a cylindrical structure, and a brush head assembly 2 is provided at the front opening of the cylinder ring 101. The brush head assembly 2 blocks the front opening so that the paint can only seep out from the brush head assembly 2. A cover 102 is welded at the rear opening of the cylinder ring 101. The cover 102 is a disc structure and completely blocks the rear opening. A paint cavity 103 is formed between the brush head assembly 2, the cylinder ring 101 and the piston assembly 3 (piston 301), and a balance cavity 104 is formed between the piston assembly 3 (piston 301), the cylinder ring 101 and the cover 102.

[0044] The atmospheric pipe 105, the balance pipe 106 and the feed pipe 107 are all welded and fixed on the cylinder ring 101. The feed pipes 107 on the cylinder ring 101 are arranged symmetrically, preferably two symmetrical feed pipes 107 are arranged, and the two feed pipes 107 are connected to the discharge pipe 403 of the coating supply assembly 4 through a three-way valve, so that uniform feeding can be achieved, and the feeding is ensured to be smooth and stable.

[0045] The brush head assembly 2 includes a brush ring 201, a seepage orifice plate 202 and a sponge 203. The brush ring 201 is arranged at the front end opening of the cylinder ring 101 as a circular ring-shaped placement base. A disc-shaped seepage orifice plate 202 is arranged inside the brush ring 201. A cylindrical sponge 203 is arranged at the front end of the seepage orifice plate 202. The paint in the paint cavity 103 flows out through the evenly distributed seepage holes on the seepage orifice plate 202, and then the paint is adsorbed on the sponge 203. During the painting operation, the sponge 203 contacts the outer wall to realize pressurized discharge, and the paint is painted on the outer wall.

[0046] The piston assembly 3 includes 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 a sealing ring 302 in contact with the inner wall of the cylinder 1. The piston 301 and the sealing ring 302 complete the absolute separation of the front and rear cavities in the cylinder 1.

[0047] The center of the rear end of the piston 301 is fixedly connected to the front end of the push rod 303, the push rod 303 extends out of the cover 102 at the rear end of the cylinder 1, and the rear end of the push rod 303 is fixedly connected to the push handle 304. The push handle 304 is convenient for operating the piston 301 and the push rod 303 to control them to move forward and backward or rotate.

[0048] The paint supply assembly 4 includes a paint bucket 401, which is used to store paint. The paint bucket 401 is provided with an air inlet pipe 402 and a discharge pipe 403. The air inlet pipe 402 is connected to the balance pipe 106 through a hose to deliver the gas in the balance chamber 104 into the paint bucket 401 to increase the pressure inside the paint bucket 401. The discharge pipe 403 is connected to the feed pipe 107 through a hose, and the discharge pipe 403 extends to the bottom of the paint bucket 401. After the pressure inside the paint bucket 401 is increased, the paint can be pressed and delivered to the paint chamber 103.

[0049] The brush ring 201 of the brush head assembly 2 is axially rotatably arranged on the cylinder ring 101, the piston 301 of the piston assembly 3 is also axially rotatably arranged on the cylinder ring 101, and the push rod 303 is axially rotatably arranged on the cover 102. The linkage assembly 5 includes a connecting rod 501, a cross seat 502, a cross bar 503 and a snap ring 504. The front end of the connecting rod 501 is fixedly connected to the cross seat 502, the cross seat 502 is fixedly arranged on the brush ring 201, the rear end of the connecting rod 501 is connected to the cross bar 503, the cross bar 503 is connected to the snap ring 504, and the snap ring 504 and the push rod 303 form an axial sliding and circumferential clamping fit.

[0050] Preferably, a cross groove is provided in the center of the retaining ring 504, and a cross ridge matching the cross groove is provided on the outer periphery of the push rod 303. The retaining ring 504 is sleeved on the push rod 303. When the push rod 303 moves forward and backward, it will not drive the connecting rod 501 to move forward and backward. However, when the push rod 303 rotates axially, it will drive the retaining ring 504 and the connecting rod 501 to rotate synchronously, and will also drive the brush ring 201 and the sponge 203 to rotate, thereby ensuring a uniform brushing effect.

[0051] The method also includes the following steps: the first step is to clean the screw holes in the exterior wall.

[0052] The second step is to align the brush head assembly 2 with the screw hole and ensure that the sponge 203 is in contact with the outer wall. The piston 301 of the piston assembly 3 is pushed forward by the push handle 304. The external gas enters the balance chamber 104 from the atmospheric pipe 105 to balance the pressure. The piston 301 of the piston assembly 3 squeezes the paint in the paint chamber 103, and the paint seeps out from the seepage orifice plate 202 and the sponge 203 of the brush head assembly 2 to the screw hole of the outer wall.

[0053] At the same time, the push handle 304 is operated to make the push rod 303 of the piston assembly 3 rotate axially along the cylinder 1. The push rod 303 of the piston assembly 3 drives the brush ring 201 of the brush head assembly 2 to rotate synchronously along the axial direction of the cylinder through the retaining ring 504, cross bar 503, connecting rod 501 and cross seat 502 of the linkage assembly 5. The brush ring 201 rotates on the outer wall with the sponge 203 to achieve uniform brushing.

[0054] In the third step, the piston 301 of the piston assembly 3 is pulled backward by the push handle 304. The piston 301 squeezes the gas in the balance chamber 104. The gas in the balance chamber 104 enters the paint bucket 401 of the paint supply assembly 4 through the balance pipe 106 and the air inlet pipe 402. The pressure in the paint bucket 401 increases, and the paint in the paint bucket 401 is pressed to the paint chamber 103 through the discharge pipe 403 and the feed pipe 107, thereby replenishing the paint chamber 103.

[0055] At the same time, the permeation orifice plate 202 can also be designed as a one-way flow structure from the inside to the outside. When the piston 301 is pulled back, the coating chamber 103 can also form a negative pressure environment to optimize the feeding effect.

[0056] Step 4: Repeat steps 1 to 3 until all screw holes are painted.

[0057] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In the scheme of this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.
