[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a paint storage device for spray painting, including a paint storage tank 1, an upper sealing cover 5 installed at the top of the paint storage tank 1, an exhaust port 18 provided at the rear end of the upper sealing cover 5, an exhaust pipe 19 connected to the rear end of the exhaust port 18, a hand pump 20 connected to the bottom of the exhaust pipe 19, a rotating handle 21 inserted at the rear end of the hand pump 20, and a regulating valve 22 connected to the bottom of the hand pump 20.

[0024] The regulating valve 22 is connected to the exhaust pipe 19 through the hand pump 20. The handle 21 is rotated at the rear end of the hand pump 20. The exhaust pipe 19 is connected to the upper sealing cover 5 through the exhaust port 18.

[0025] Specifically, such as Figure 3 As shown, by setting up a vacuum structure, when in use, after pouring paint into the paint storage bucket 1, the upper sealing cap 5 is placed over the top of the paint storage bucket 1, and the paint storage bucket 1 and the upper sealing cap 5 are connected and sealed together by the sealing lock 6. Then, the regulating valve 22 at the bottom of the hand pump 20 is turned, and the rotating handle 21 is rotated at the rear end of the hand pump 20. The rotating handle 21 drives the impeller inside the hand pump 20, which draws the air inside the paint storage bucket 1 out through the exhaust port 18 and exhaust pipe 19 at the rear end of the upper sealing cap 5 and discharges it through the regulating valve 22 at the bottom of the hand pump 20, thereby reducing the air inside the paint storage bucket 1 and realizing the vacuum function.

[0026] A stirring handle 3 is inserted into the top of the upper sealing cover 5. A stirring blade 12 is connected to the bottom of the stirring handle 3. An extension rod 13 is connected to the right side of the stirring blade 12. A scraper 14 is connected to the right side of the extension rod 13. A lower support base 15 is installed at the bottom of the inside of the paint storage tank 1.

[0027] The stirring handle 3 is inserted into the bottom end of the upper sealing cover 5 and connected to the stirring blade 12 at the bottom of the upper sealing cover 5. The upper sealing cover 5, carrying the stirring blade 12 at the bottom, is inserted into the top of the lower support seat 15 installed inside the paint storage tank 1. The scraper 14 is connected to the stirring blade 12 through the extension rod 13, and the scraper 14 contacts the inner wall of the paint storage tank 1.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, by setting up a stirring and scraping structure, after the paint is poured into the paint storage tank 1, the stirring blade 12 at the bottom of the upper sealing cover 5 is inserted into the paint storage tank 1 and engaged with the lower support base 15 at the bottom of the paint storage tank 1, so that the upper sealing cover 5 covers the top of the paint storage tank 1. By rotating the stirring handle 3 on the top of the upper sealing cover 5, the stirring handle 3 drives the stirring blade 12 at the bottom of the upper sealing cover 5 to stir the paint inside the paint storage tank 1. At the same time, the scraper 14 scrapes the inner wall of the paint storage tank 1 by the stirring blade 12 and the extension rod 13, so that the paint inside the paint storage tank 1 is mixed evenly, which is convenient for subsequent spraying, thus realizing the stirring and scraping function.

[0029] The top left side of the upper sealing cover 5 is provided with a liquid inlet 16, the top of the liquid inlet 16 is connected to a telescopic bucket 11, a filter screen 17 is installed inside the top of the telescopic bucket 11, and the top of the telescopic bucket 11 is covered by the upper liquid inlet cover 2.

[0030] The telescopic bucket 11 extends and retracts at the top of the upper liquid inlet cover 2. The telescopic bucket 11 is connected to the paint storage bucket 1 through the liquid inlet 16. The upper liquid inlet cover 2 covers and snaps onto the top of the telescopic bucket 11. The filter screen 17 is fixed inside the top of the telescopic bucket 11.

[0031] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, by setting up a telescopic filtration structure, when in use, the upper liquid inlet cover 2 is pulled out from the top of the telescopic bucket 11 on the left side of the top of the upper sealing cover 5, and then the telescopic bucket 11 is extended from the top of the upper sealing cover 5. Then, the paint is passed through the telescopic bucket 11 and the liquid inlet 16 into the interior of the paint storage tank 1. The paint is filtered by the filter screen 17 inside the telescopic bucket 11, reducing the damage of the paint to spraying equipment, thereby realizing the telescopic filtration function.

[0032] Working principle: In use, after the paint is poured into the paint storage tank 1, the stirring blade 12 at the bottom of the upper sealing cap 5 is inserted into the paint storage tank 1 and engaged with the lower support base 15 at the bottom of the paint storage tank 1, so that the upper sealing cap 5 covers the top of the paint storage tank 1. The paint storage tank 1 and the upper sealing cap 5 are connected and sealed together by the sealing lock 6. The stirring handle 3 is rotated on the top of the upper sealing cap 5, so that the stirring handle 3 drives the stirring blade 12 at the bottom of the upper sealing cap 5 to stir the paint inside the paint storage tank 1. At the same time, the scraper 14, driven by the stirring blade 12 and the extension rod 13, stirs the oil in the storage tank. The inner wall of the paint bucket 1 is scraped to ensure that the paint inside the paint bucket 1 is mixed evenly. Then, the drain valve 9 on the left side of the conveying pipe 8 at the bottom left side of the paint bucket 1 is connected to the pipe body. By rotating the drain valve 9, the paint inside the paint bucket 1 is transported to the inside of the pipe body through the conveying pipe 8 and the drain valve 9. When replenishing the paint, the upper liquid inlet cover 2 is pulled out from the top of the telescopic bucket 11 on the left side of the top of the upper sealing cover 5. Then, the telescopic bucket 11 is extended from the top of the upper sealing cover 5. The paint is then fed into the inside of the paint bucket 1 through the telescopic bucket 11 and the liquid inlet 16. The paint is filtered by the filter screen 17 inside the telescopic bucket 11.
