Detailed Description

The drawings are for illustrative purposes only and are not to be construed as limiting the patent;

for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product;

it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

Example 1

As shown in fig. 1 to 4, the embodiment provides a spray gun, which includes a spray gun body 1, a spray head 101, a trigger 102, an air inlet 103 and a feeding port 104 are arranged on the spray gun body 1, the spray gun further includes a shielding plate 2 and a connecting piece 3, the shielding plate 2 is arranged on a side surface of the spray head 101, and the spray gun body 1 and the shielding plate 2 are connected through the connecting piece 3.

During spraying, if the positions of the hanging pieces, the murals, the wall cabinets and the like which are not suitable for spraying are arranged on the wall surface, the positions can be separated from the spray head 101 of the spray gun through the baffle plate, and the coating is prevented from being sprayed to the positions. Through the spray gun spraying of this embodiment, objects such as no longer using newspaper, plastic film shelter from, have improved spraying efficiency.

In the specific implementation process, the connecting piece 3 is a cylindrical structure, and is perpendicular to the side surface of the spray gun body 1, and one end of the connecting piece is connected with the side surface of the spray gun body 1.

In the specific implementation process, one end of the connecting piece 3 is detachably connected with the side surface of the spray gun body 1. When the wall with no improper spraying position is sprayed, the connecting piece 3 and the shielding plate 2 can be detached together, and the state of the common spray gun can be recovered.

In the specific implementation process, the other end of the connecting piece 3 is rotatably connected with the shielding plate 2. When the shielding plate 2 is required to shield, the shielding plate 2 can be adjusted to the side of the spray head 101, and the position which is not suitable for spraying is separated from the spray head 101 of the spray gun through the shielding plate 2, so that the coating is prevented from being sprayed to the position. As shown in fig. 5, when the shielding plate 2 is not needed, the shielding plate 2 can be rotated backward by 90 degrees, and the shielding plate 2 can shield the paint particles rebounded from the wall, so as to prevent the paint particles from dirtying the clothes and skin of the operator. As shown in fig. 6, the shielding plate 2 can also be rotated back by 90 degrees to prevent the shielding plate 2 from blocking the view of the operator.

In a specific implementation process, the shielding plate 2 is a rectangular plate-shaped structure.

In the specific implementation process, one side of the rectangular shielding plate 2 is provided with a U-shaped groove 201, a pair of pits are arranged at the opposite positions of the inner walls of the U-shaped groove 201, the side wall of the cylindrical connecting piece 3 is provided with a pair of bulges 301 matched with the pits, and the shielding plate 2 and the connecting piece 3 are in interference fit with the bulges 301 through the pits. The baffle plate 2 and the connecting piece 3 are in interference fit with each other through the concave pits and the protrusions 301, so that the connection stability is ensured, and the relative rotation of the baffle plate 2 and the connecting piece 3 is not influenced.

In the specific implementation process, the edge of the shielding plate 2 is covered with a rubber sleeve 202. The rubber sleeve 202 can improve the fit degree of the shielding plate 2 and the wall, and reduce the possibility that paint is sprayed to the position unsuitable for spraying through the gap between the shielding plate 2 and the wall as much as possible.

Example 2

The embodiment provides a spraying device, which comprises the spray gun of embodiment 1, an air pump and a material barrel, wherein an air inlet interface 103 of the spray gun is communicated with the air pump, and a feeding interface 104 of the spray gun is communicated with the material barrel.

During spraying, the trigger 102 is pulled, and the compressed air in the air pump enters the spray gun and is sprayed out from the spray head 101, so that the paint is sprayed out together with the high-speed air flow in the process, and the spraying process is realized.

In the specific implementation process, if paint is required to be sprayed, the paint is filled in the charging barrel; if coating is required to be sprayed, the barrel is filled with the coating.
