[0002] During the car beautification process, it is necessary to use a paint spraying device to spray paint on the corresponding position of the car surface to achieve the effect of beautifying the car. The existing paint spraying device mainly includes a spray gun and a tank body for storing paint. The paint is injected into the spray gun through the tank body, and then the paint is atomized and sprayed out through the spray gun. However, when the tank body of the existing paint spraying device is disassembled, in order to protect the paint and the inside of the tank body, it is necessary to use a sealing cover to seal the connection between the two respectively. Obviously, the sealing method using the sealing cover is more troublesome, and after the sealing cover is removed, it is difficult to avoid it from being lost, which undoubtedly limits the performance of the paint spraying device. For this reason, we propose a paint spraying device for car beautification. Utility Model Content

[0023] See also Figure 1-4 The utility model provides a technical solution: a paint spraying device for automobile beauty, comprising a spray gun 1 and a tank body 11, the spray gun 1 and the tank body 11 are interconnected through a connector 2, the connector 2 comprises a first connector 21 fixedly connected to the spray gun 1 and a second connector 22 fixedly connected to the tank body 11, the first connector 21 and the second connector 22 are respectively fixedly installed with a first sealing ring 23 and a second sealing ring 24 on their inner walls, and the first sealing ring 23 and the second sealing ring 24 are respectively fixedly installed with a first sealing plate 232 and a second sealing plate 242 on their back end surfaces through a first spring 234 and a second spring 244, and the peripheries of the first sealing plate 232 and the second sealing plate 242 are clearance-matched with the inner walls of the first connector 21 and the second connector 22, and a push rod 25 in contact with the lower end surface of the first sealing plate 232 is fixedly installed on the upper end surface of the second sealing plate 242.

[0024] Working principle: When the tank body 11 is installed, the upper end of the push rod 25 contacts the first sealing plate 232, and pushes the first sealing plate 232 to move upward and pushes the second sealing plate 242 to move downward, so that the first sealing plate 232 and the second sealing plate 242 are separated from the first sealing ring 23 and the second sealing ring 24 respectively, so that the first sealing ring 23 and the second sealing ring 24 can be opened, so that the paint inside the tank body 11 can enter the spray gun 1 through the second connector 22 and the first connector 21;

[0025] When the tank body 11 is disassembled, the push rod 25 and the first sealing plate 232 are separated from each other. At this time, under the action of the first spring 234 and the second spring 244 restoring their deformation, the first sealing plate 232 and the second sealing plate 242 can be driven to reset, so that the two can be re-fitted with the first sealing ring 23 and the second sealing ring 24 respectively, so that the first connecting head 21 and the second connecting head 22 can be sealed, and foreign impurities can be prevented from entering the spray gun 1 and the tank body 11, thereby achieving the effect of protecting the paint channel inside the tank body 11 and the spray gun 1.

[0026] Example 2

[0027] The first and second sealing plates 232 and 242 are respectively fixedly mounted with a first slide bar 233 and a second slide bar 243 plugged with the first and second sealing rings 23 and 24 on their facing end surfaces. The first and second springs 234 and 244 are respectively sleeved around the first and second slide bars 233 and 243 .
