Description

Technical Field

[0001] This utility model relates to the field of paint spray gun technology, specifically to a multifunctional paint spray atomization adjustment spray gun for architectural decoration. Background Technology

[0002] A spray gun is a spraying device that uses the rapid release of liquid or compressed air as power. It is generally divided into two types: standard pressure and pressurized pressure. Among them, the paint spray gun is a type of spray gun with a wide range of applications. In the process of building interior decoration, paint spray guns are often used for painting.

[0003] A search revealed existing technology (publication number: CN217400256U), which describes "a paint spray gun for interior decoration, comprising a gun body, a gun barrel, and a cartridge. The gun body is fixedly installed on the right side of the gun body, and the cartridge is located on the top left side of the gun barrel. A feed hopper is fixedly installed at the right end inside the gun barrel. Inside the feed hopper, from left to right, a second paint outlet plate and a first paint outlet plate are arranged sequentially. The upper and lower ends of the first paint outlet plate are fixedly connected to the inner wall of the feed hopper. A rotating shaft is rotatably connected to the left side of the first paint outlet plate. The beneficial effect of this utility model is that by using a rotating handle, a transmission rod, a first bevel gear, a second bevel gear, a rotating shaft, and the first and second paint outlet plates in combination, the size of the mesh of the first paint outlet plate can be changed, allowing the paint spray gun to adjust the amount of paint sprayed according to the actual usage conditions, so that the paint spray gun can spray paint in different environments, greatly meeting people's usage needs."

[0004] While existing paint spray guns for interior decoration have achieved mixing and adjustment of the amount of paint sprayed, they still have some shortcomings: the nozzle structure of existing paint spray guns for interior decoration is relatively simple, which makes it impossible to expand or change the spraying method according to the actual building area and shape, resulting in low spraying efficiency. Secondly, the paint canisters involved need to be opened and refilled with new paint after each use, which is quite troublesome. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a multi-functional paint spraying atomization adjustment spray gun for architectural decoration is provided to solve the problems mentioned in the background.

[0006] To achieve the above objectives, a multifunctional paint spraying atomization adjustment spray gun for architectural decoration is provided, comprising: a gun body, a nozzle assembly connected to the front end of the gun body, and a liquid storage tank connected to the lower side of the gun body; the nozzle assembly includes an original nozzle fixedly connected to the gun body and a second atomizing nozzle detachably connected to the original nozzle; a rotating tube connected to the outer end of the original nozzle, and a horizontal tube connected to the outer end of the rotating tube; a first atomizing nozzle connected to the outer wall of the horizontal tube; the liquid storage tank includes a tank body, a cover provided at the upper end of the tank body, a suction tube inserted inside the tank body, and a liquid pump provided inside the tank body; a suction pipe connected to the inlet end of the liquid pump, a suction tube connected to the inlet end of the suction pump, a movable tube connected to the lower end of the suction tube via a spiral flexible hose, and an outlet pipe connected to the outlet end of the liquid pump.

[0007] Furthermore, the original nozzle has an internal thread on its inner wall and an external thread on its outer wall, and the outer end of the original nozzle is connected to a connecting sleeve via the external thread.

[0008] Furthermore, an annular plate is fixedly connected to the outer end of the connecting sleeve, and a fixing sleeve is fixedly connected to the outer end of the annular plate, and a connecting pipe is fixedly connected to the outer end of the fixing sleeve.

[0009] Furthermore, the outer end of the connecting pipe is provided with a sealing ring, and a bearing is provided inside the sealing ring. The rotating pipe is rotatably connected to the connecting pipe through the bearing, and a locking bolt is screwed onto the outer wall of the connecting pipe.

[0010] Furthermore, the suction tube passes through the cover and connects to the inner cavity of the gun body, and the cover and the can body are connected by threads.

[0011] Furthermore, the pump is equipped with a sealing cover on its outer side, which is fixed to the inner wall of the tank, and the outlet pipe passes through the sealing cover.

[0012] Furthermore, a locking block is fixed to the outer wall of the tank, and the locking block is a pair of arc-shaped blocks with opposite arc openings. The inner arc groove wall of the arc-shaped block is provided with a rubber pad, and the movable tube is locked in the arc-shaped block.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By using the connecting sleeve, annular plate, and fixing sleeve connected to the outer end of the original nozzle, as well as the connecting pipe and locking bolt, it is easy to connect the rotating pipe on the outside of the connecting pipe to it, thereby facilitating the adjustment of the spraying angle of the horizontal pipe. The installation of the horizontal pipe increases the spraying area, which improves the spraying efficiency when painting walls with a larger building area. When used for spraying small building walls, the second nozzle can be replaced on the original nozzle by disassembling the connecting sleeve, so that the original nozzle structure can be used for painting, improving the flexibility of use.

[0015] 2. By utilizing the tank body and the internal pump of the storage tank, when the paint inside the tank is used up, the suction pipe can be removed, the spiral hose of the suction pipe can be pulled out, and the lower end of the suction pipe can be inserted into the paint bucket. Then, the suction pump can be started to pump the paint through the outlet pipe. This avoids directly drawing paint from the outside of the storage tank into the inside of the storage tank, eliminating the need to open the tank to refill the paint, thus achieving convenience in use.

[0022] Reference Figures 1 to 5As shown, this utility model provides a multi-functional paint spraying atomization adjustment spray gun for architectural decoration, including: a gun body 1, a nozzle assembly 2 connected to the front end of the gun body 1, and a liquid storage tank 3 connected to the lower side of the gun body 1. The nozzle assembly 2 includes an original nozzle 21 fixedly connected to the gun body 1 and a second atomizing nozzle 29 detachably connected to the original nozzle 21. A rotating tube 26 is connected to the outer end of the original nozzle 21, and a horizontal tube 27 is connected to the outer end of the rotating tube 26. Meanwhile, the outer wall of the horizontal pipe 27 is connected to the first atomizing nozzle 28. The storage tank 3 includes a tank body 31, and the upper end of the tank body 31 is provided with a cover 32. A suction pipe 33 is inserted into the tank body 31. A liquid pump 35 is provided inside the tank body 31. The liquid inlet end of the liquid pump 35 is connected to a liquid suction pipe 352. The lower end of the liquid suction pipe 352 is connected to a movable pipe 354 through a spiral flexible hose 353. The liquid outlet end of the liquid pump 35 is connected to a liquid outlet pipe 351.

[0023] In this embodiment, the gun body 1, the nozzle assembly 2, and the liquid storage tank 3 constitute the main structure of the multifunctional paint spraying atomization adjustment spray gun for building decoration involved in this application.

[0024] The inner and outer structures of the gun body 1 are consistent with the structure and working principle of the gas-driven spray gun under the existing technology.

[0025] Specifically, the original nozzle 21 is designed with a straight pipe structure, and the second atomizing nozzle 29 is connected to the original nozzle 21 by a thread. It is used for spraying small areas of architectural decorative walls, which can save paint.

[0026] Specifically, multiple first atomizing nozzles 28 are installed on the same side of the outer wall of the horizontal tube 27, which increases the diffusion area of ​​the sprayed paint.

[0027] like Figure 2 and Figure 3 In the original nozzle 21, the inner wall is provided with an internal thread 211 and the outer wall is provided with an external thread 212. The outer end of the original nozzle 21 is connected to a connecting sleeve 22 through the external thread 212. The outer end of the connecting sleeve 22 is fixedly connected to an annular plate 23, and the outer end of the annular plate 23 is fixedly connected to a fixing sleeve 24. The outer end of the fixing sleeve 24 is fixedly connected to a connecting pipe 25. The outer port of the connecting pipe 25 is provided with a sealing ring 253, and the inner side of the sealing ring 253 is provided with a bearing 252. The rotating pipe 26 is rotatably connected to the connecting pipe 25 through the bearing 252. At the same time, a locking bolt 251 is screwed onto the outer wall of the connecting pipe 25.

[0028] As a preferred implementation, the annular plate 23 is provided to block the splashed paint and prevent it from getting on the hands. That is, the outer diameter of the annular plate 23 can be enlarged to cover the handle of the gun body 1.

[0029] As a preferred embodiment, by setting the rotating tube 26 and the locking bolt 251, the angle of the horizontal tube 27 can be easily adjusted, so that it can be adjusted to a horizontal state to move up and down for spraying, or it can be adjusted to a vertical state to move left and right for spraying.

[0030] like Figure 1 and Figure 5 In the middle, the suction tube 33 passes through the cover 32 and connects to the inner cavity of the gun body 1, and the cover 32 and the tank body 31 are threaded together. The outer side of the pump 35 is provided with a sealing cover 34, and the sealing cover 34 is fixed to the inner wall of the tank body 31. The outlet tube 351 passes through the sealing cover 34. The outer wall of the tank body 31 is fixed with a locking block 355, and the locking block 355 is a pair of arc-shaped blocks with opposite arc openings. The inner arc groove wall of the arc-shaped block is provided with a rubber pad, and the movable tube 354 is locked in the arc-shaped block.

[0031] Specifically, the upper end of the suction tube 33 is originally connected to the gun body 1, and is designed to be detachable. Alternatively, the liquid storage tank 3 can be separated from the suction tube 33 and then injected with paint.

[0032] Specifically, the spiral hose 353 has elastic shrinkage properties, which makes it easy to retract and abut against the outer wall of the tank body 31 after the movable tube 354 is fixed by the clamp 355. At the same time, a flow control valve is installed on the movable tube 354.

[0033] As another preferred implementation, in specific operation, the movable tube 354 can be inserted and fixed to the paint bucket, and the liquid pump 35 can be kept on. The liquid inlet volume can be controlled by the flow control valve. After the liquid inlet volume is matched with the spray volume of the gun body 1, continuous paint delivery can be achieved, and a long-term continuous spray head effect can be achieved.

[0034] In use, the connecting sleeve, annular plate, and fixing sleeve connected to the outer end of the original nozzle, along with the connecting pipe and locking bolts, facilitate the movable connection of the rotating pipe on the outside of the connecting pipe. This allows for easy adjustment of the spraying angle of the horizontal pipe, and the horizontal installation increases the spraying area. This improves painting efficiency when painting large building walls. When painting small building walls, the second nozzle can be replaced with the original nozzle by disassembling the connecting sleeve, allowing for painting with the original nozzle structure and increasing flexibility. The liquid storage tank, including the tank body and the internal pump, allows the extraction pipe to be removed when the paint inside the tank is used up. The spiral hose of the extraction pipe is then pulled open, and the lower end of the extraction pipe is inserted into the paint bucket. The extraction pump is then started, and the paint is drawn through the outlet pipe. This avoids directly drawing paint from the outside of the storage tank into the inside, eliminating the need to open the tank to refill the paint, thus ensuring convenience.

[0035] This utility model of a multi-functional paint spraying atomization adjustment spray gun for building decoration can effectively solve the problems mentioned in the background technology. Based on the existing multi-functional paint spraying atomization adjustment spray gun technology for building decoration, it can replace two types of nozzles, which can improve spraying efficiency and save paint, and at the same time has a more convenient paint addition effect.
