[0002] During the renovation and construction process, the final process on the walls is to apply latex paint. There are two types of latex paint: roller coating and spray coating. Spray coating produces a smooth and delicate finish and is easy to apply, and is generally used for ceilings.

[0003] For example, the paint spraying device disclosed in the utility model with authorization announcement number CN219548282U scrapes the paint off the inner wall of the pressure tank by a piston, which can make full use of the paint and prevent the paint from adhering and solidifying on the inner wall of the pressure tank. However, since the existing paint spraying device itself does not have a mixing device, the paint spraying device cannot be fully mixed when it is used, resulting in uneven mixing of the sprayed paint. Moreover, after a long period of standing, the paint stored inside the spraying device may solidify, resulting in poor overall practicality. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a paint spraying device that solves the problem that existing paint spraying devices scrape paint off the inner wall of a pressure tank using a piston, which not only makes full use of the paint but also prevents the paint from adhering and solidifying on the inner wall of the pressure tank. However, because existing paint spraying devices do not have a mixing device, the paint sprayed is not fully mixed when used, resulting in uneven mixing of the sprayed paint. Moreover, after a long period of standing, the paint stored inside the spraying device may solidify, leading to poor overall practicality.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a paint spraying device, including a gun body, a material extraction pipe fixedly connected to the bottom of one end of the gun body, and a material storage cylinder connected to the other end of the material extraction pipe. A sealing cover is provided at the bottom of the material storage cylinder, and a sealing seat is provided at one end of the sealing cover.

An installation sleeve is fitted on the outer surface of the rotating shaft, and a stirring rod is provided on the side wall of the installation sleeve. An auxiliary blade is fitted on the outer surface of the stirring rod. An annular groove is opened at the bottom of the material storage cylinder, and an adjustment structure is connected to the bottom of the other end of the gun body.

[0006] As a preferred technical solution of this utility model, the adjustment structure includes a connecting seat, a fixed sleeve, a handle, and an extension rod. The connecting seat is fixedly connected to the bottom of the gun body at the end away from the feed tube, and the bottom of the connecting seat is connected to the fixed sleeve. The handle is distributed below the fixed sleeve, and the top of the handle is fixedly connected to the extension rod.

[0007] As a preferred embodiment of this utility model, a guide groove is provided on the outer surface of the extension rod, a return spring is fixedly connected to the inner side of one end of the extension rod, and a locking rod is fixedly connected to the other end of the return spring. An auxiliary sliding plate is sleeved on the outer side of one end of the locking rod.

[0008] As a preferred embodiment of this utility model, the inner wall of the fixing sleeve is provided with a slide rail, and the outer surface of the fixing sleeve is provided with a locking hole.

[0009] As a preferred embodiment of this utility model, the mounting sleeves are equidistantly distributed along the outer surface of the rotating shaft, and the stirring rods are symmetrically distributed along the vertical center line of the mounting sleeves.

[0010] In a preferred embodiment of this invention, the locking rod is slidably connected to the extension rod via the return spring, and the outer diameter of the locking rod is adapted to the inner diameter of the lock hole.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. By combining the motor, rotating shaft, stirring rod, and auxiliary blades, the spraying material fed into the storage cylinder can be easily and thoroughly mixed and stirred, thereby achieving effective mixing between materials and improving the subsequent spraying effect. At the same time, the stirring structure can prevent the paint inside the storage cylinder from solidifying when it is left to stand for a long time, making it more practical. The operation of the motor will cause the rotating shaft to drive the stirring rod and auxiliary blades to rotate, and the rotation of the two can be used to mix the paint, while also preventing the paint from solidifying.

[0013] 2. By combining the grip, extension rod, and fixed sleeve, the extension length of the gun body can be adjusted according to actual usage needs, thus allowing for better spraying of different areas. When the grip pulls the extension rod, it slides inside the fixed sleeve, thereby adjusting the length of the entire structure through the movement of the extension rod, which facilitates better spraying of different areas.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0020] Example

[0021] Please refer to Figure 1 As shown, this utility model provides a paint spraying device, including a gun body 1. A material extraction pipe 2 is fixedly connected to the bottom of one end of the gun body 1, and a material storage cylinder 3 is connected to the other end of the material extraction pipe 2. A sealing cover 4 is provided at the bottom of the material storage cylinder 3, and a sealing seat 5 is provided at one end of the sealing cover 4. A retaining ring 6 is provided around the sealing seat 5, and a positioning bolt 7 passes through the inner side of the retaining ring 6. A motor 8 is fixedly installed at the end of the sealing cover 4 away from the sealing seat 5, and a rotating shaft 9 is connected to the output end of the motor 8. An installation sleeve 10 is sleeved on the outer surface of the rotating shaft 9, and a stirring rod 11 is provided on the side wall of the installation sleeve 10. An auxiliary blade 12 is sleeved on the outer surface of the stirring rod 11. An annular groove 13 is opened at the bottom of the material storage cylinder 3, and an adjustment structure is connected to the bottom of the other end of the gun body 1.

[0022] In use, the spraying material is fed into the inside of the storage cylinder 3 and mixed and stirred. Then, the control panel and other structures on the surface of the gun body 1 enable the pump inside the gun body 1 to work, thereby drawing the spraying material stored in the storage cylinder 3 into the inside of the gun body 1 through the extraction pipe 2, so that it can be sprayed out through the nozzle to achieve the purpose of spraying.

[0023] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the gun body 1 is fixedly connected to a material extraction pipe 2 at one end of the bottom of the gun body 1, and a storage cylinder 3 is connected to the other end of the material extraction pipe 2. A sealing cover 4 is provided at the bottom of the storage cylinder 3, and a sealing seat 5 is provided at one end of the sealing cover 4. A retaining ring 6 is provided around the sealing seat 5, and a positioning bolt 7 passes through the inner side of the retaining ring 6. A motor 8 is fixedly installed at the end of the sealing cover 4 away from the sealing seat 5, and a rotating shaft 9 is connected to the output end of the motor 8. An installation sleeve 10 is fitted on the outer surface of the rotating shaft 9, and a stirring rod 11 is provided on the side wall of the installation sleeve 10. The installation sleeves 10 are evenly distributed along the outer surface of the rotating shaft 9, and the stirring rods 11 are symmetrically distributed along the vertical center line of the installation sleeve 10. An auxiliary blade 12 is fitted on the outer surface of the stirring rod 11. An annular groove 13 is opened at the bottom of the storage cylinder 3, and an adjustment structure is connected to the bottom of the other end of the gun body 1.

[0024] In use, firstly, the sealing cap 4 and the sealing seat 5 are engaged in the opening at the bottom of the storage cylinder 3. The sealing seat 5 is used to improve the sealing performance between the sealing cap 4 and the storage cylinder 3. Then, the retaining ring 6 is inserted into the inner side of the annular groove 13. At this time, multiple positioning bolts 7 are turned. By combining the positioning bolts 7 and the bolt groove, the sealing cap 4 and the storage cylinder 3 can be quickly connected with a higher sealing performance. When the spraying material is fed into the inner side of the storage cylinder 3, the operation of the motor 8 will cause the rotating shaft 9 to drive the mounting sleeve 10 to rotate. The rotation of the mounting sleeve 10 will cause the stirring rod 11 to rotate. At the same time, the auxiliary blade 12 will also move, thereby achieving a thorough mixing of the paint. The continuously rotating stirring rod 11 can also effectively prevent the paint from solidifying due to prolonged standing, making it more practical.

[0025] As a further implementation of this embodiment, such as Figure 1 and Figure 4As shown, the adjustment structure includes a connecting seat 14, a fixed sleeve 15, a handle 16, and an extension rod 17. The connecting seat 14 is fixedly connected to the bottom of the gun body 1 at the end away from the feed tube 2, and the bottom of the connecting seat 14 is connected to the fixed sleeve 15. The handle 16 is distributed below the fixed sleeve 15, and the top of the handle 16 is fixedly connected to the extension rod 17. The outer surface of the extension rod 17 is provided with a guide groove 18. One end of the extension rod 17 is fixedly connected to a return spring 19, and the other end of the return spring 19 is fixedly connected to a locking rod 20. The locking rod 20 is slidably connected to the extension rod 17 through the return spring 19, and the outer diameter of the locking rod 20 is adapted to the inner diameter of the locking hole 23. One end of the locking rod 20 is fitted with an auxiliary sliding plate 21. The inner wall of the fixed sleeve 15 is provided with a slide rail 22, and the outer surface of the fixed sleeve 15 is provided with a locking hole 23.

[0026] When the handle 16 moves longitudinally, it will drive the extension rod 17 to move longitudinally as well. Then, the extension rod 17 slides along the slide rail 22 through the guide groove 18 on its surface to improve the stability of the extension rod 17 during longitudinal movement. After the extension rod 17 extends to a certain length, the reverse force generated by the deformation of the return spring 19 will push the locking rod 20 laterally, thereby inputting one end of the locking rod 20 into the inside of the lock hole 23 to achieve the positioning of the extension length of the extension rod 17. The auxiliary slide plate 21 can effectively prevent the locking rod 20 from shifting position during lateral movement. The fixed sleeve 15 is rotatably connected to the gun body 1 through the connecting seat 14, which makes it convenient to adjust the tilt of the gun body 1 according to the actual spraying requirements.

[0027] Specific working principle:

[0028] In use, firstly, the sealing cap 4 and the sealing seat 5 are engaged in the opening at the bottom of the storage cylinder 3. The sealing seat 5 improves the sealing performance between the sealing cap 4 and the storage cylinder 3. Then, the retaining ring 6 is inserted into the inner side of the annular groove 13. At this time, multiple positioning bolts 7 are tightened. By combining the positioning bolts 7 and the bolt grooves, a quick connection between the sealing cap 4 and the storage cylinder 3 can be achieved, and the sealing performance is also higher. When the spraying material is fed into the inner side of the storage cylinder 3, the operation of the motor 8 will cause the rotating shaft 9 to drive the mounting sleeve 10 to rotate. The rotation of the mounting sleeve 10 will cause the stirring rod 11 to rotate, and the auxiliary blade 12 will also move accordingly, thereby achieving a thorough mixing of the paint. At the same time, the continuously rotating stirring rod 11 can effectively prevent the paint from solidifying due to prolonged standing, making it more practical. When the handle 16 moves longitudinally, it will drive the extension rod 17 to move longitudinally as well. Then, the extension rod 17 passes through... The extension rod 17 slides along the slide rail 22 through the guide groove 18 on its surface to improve the stability of the extension rod 17 during longitudinal movement. Then, when the extension rod 17 extends to a certain length, the reverse force generated by the deformation of the return spring 19 will push the locking rod 20 laterally, thereby inputting one end of the locking rod 20 into the inside of the lock hole 23, thus achieving the positioning of the extension length of the extension rod 17. The auxiliary slide plate 21 can effectively prevent the locking rod 20 from shifting position during lateral movement. The fixed sleeve 15 is rotatably connected to the gun body 1 through the connecting seat 14, which can facilitate the subsequent adjustment of the tilt of the gun body 1 according to the actual spraying requirements. During spraying, the control panel and other structures on the surface of the gun body 1 enable the structure with a material pump inside the gun body 1 to work, thereby drawing the spraying material stored in the storage cylinder 3 into the inside of the gun body 1 through the material extraction pipe 2, so that it can be sprayed out through the nozzle to achieve the purpose of spraying.
