Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0020] Example

[0021] This embodiment describes a paint spraying device for building construction, such as... Figure 1 , Figure 2 and Figure 4 As shown, the device includes a body 10, which is a paint spraying device in the prior art. Its structure and components are the same as those in the prior art. A paint spraying device is a coating equipment whose main function is to spray paint evenly and quickly onto the surface of a roof and walls. Existing paint spraying devices mainly consist of a spray gun, a compressor, an air pipe, an oil pipe, a suction pipe, etc. The working principle of a paint spraying device is usually to spray paint onto the surface of a roof and walls by using compressed air. When the paint spraying device starts working, paint is sprayed out from the spray gun, and at the same time, the air on the nozzle disperses the paint into fine particles and sprays them onto the surface of the roof and walls to form a uniform coating.

[0022] The suction tube of the main body 10 is detachably fitted with a connecting cover 1. A sealing ring 2 is provided inside the connecting cover 1 to seal the gap between the suction tube and the connecting cover 1. When the suction tube enters the connecting cover 1, the sealing ring 2 prevents paint from passing through the gap. Figure 1 As shown, screws are installed on the outer wall of the connecting cover 1. By rotating the screws, one end of the screws presses against the suction pipe, thereby detachably fixing the connecting cover 1 to the suction pipe.

[0023] A rotating shaft 9 is installed inside the connecting cover 1, with one end of the rotating shaft 9 passing independently through the bottom of the connecting cover 1 and located outside the connecting cover 1; for example Figure 1 As shown, a through hole with internal and external communication is provided at the center of the bottom of the connecting cover 1. The rotating shaft 9 passes through the through hole, and a bearing is provided between the rotating shaft 9 and the wall of the through hole, allowing the rotating shaft 9 to rotate freely. A mounting bracket 3 is fixed inside the connecting cover 1, and one end of the rotating shaft 9 is independently mounted on the mounting bracket 3. Figure 1 As shown, a through hole for inserting a section of the rotating shaft 9 is provided at the center of the mounting bracket 3. A bearing is provided between the rotating shaft 9 and the wall of the through hole, so that the rotating shaft 9 can rotate freely. The mounting bracket 3 can position and support the rotating shaft 9.

[0024] An agitator 8 is mounted on the outer end of the rotating shaft 9. The agitator 8 includes a mounting sleeve, which is fitted onto the end of the rotating shaft 9 located outside the connecting cover 1. Several agitator plates are evenly fixed along the circumference of the outer wall of the mounting sleeve, and all agitator plates are inclined. During the rotation of the rotating shaft 9, the agitator 8 will rotate. During the rotation, all agitator plates on the agitator 8 will agitate the paint in the paint bucket. Because the agitator plates are inclined, they will move the paint upward into the bucket during the rotation, thereby preventing the paint components from settling at the bottom of the bucket and making the paint components in the bucket more evenly agitated.

[0025] A water wheel 4 is installed at one end of the rotating shaft 9 inside the connecting cover 1. The water wheel 4 includes a fixed sleeve, which is fitted onto the end of the rotating shaft 9 inside the connecting cover 1. Several fan blades are evenly fixed on the outer wall of the fixed sleeve along its circumference, and all fan blades are inclined. The water wheel 4 is located inside the connecting cover 1. Therefore, when paint passes through the water wheel 4, the paint will come into contact with the fan blades on the water wheel 4. Because all fan blades are inclined, the thrust applied by the paint when it passes through will be converted into the directional force of the water wheel 4 by the fan blades. The principle is similar to that of a windmill. During the rotation of the water wheel 4, the stirring wheel 8 will be driven to rotate through the rotating shaft 9.

[0026] The connecting cover 1, located between the water wheel 4 and the stirring wheel 8, has several inlets that communicate with each other inside and out. All inlets are evenly distributed along the circumference of the connecting cover 1. When the stirring wheel 8 finishes stirring the paint and moves the stirred paint upward, a suction force is generated at the suction pipe. The paint in the area of ​​the connecting cover 1 will enter the connecting cover 1 from each inlet and flow through the connecting cover 1 into the suction pipe. All inlets are inclined towards the stirring wheel 8, which allows all inlets to more accurately absorb the stirred paint when absorbing it.

[0027] To elaborate further, such as Figure 1 , Figure 2 and Figure 4 As shown, this embodiment preferably includes an anti-collision ring 6, which is spaced around and aligned with the outside of the stirring wheel 8. Several connecting rods 5 are fixed between the anti-collision ring 6 and the connecting cover 1. Figure 4As shown, all connecting rods 5 are evenly distributed along the circumference. The anti-collision ring 6 is connected to the connecting cover 1 via the connecting rods 5, ensuring the anti-collision ring 6 remains aligned with the stirring wheel 8. When the end of the suction pipe oscillates inside the paint bucket, the anti-collision ring 6 protects the stirring wheel 8, preventing it from colliding with the bucket wall and allowing the stirring wheel 8 to rotate undisturbed. Several support rods 7 are fixed to the bottom of the anti-collision ring 6, evenly distributed along the circumference. When the stirring wheel 8 is inside the paint bucket, the support rods 7 support the anti-collision ring 6, thus ensuring the stirring wheel 8 remains aligned with the bucket wall. A gap is maintained between the bottoms of the buckets to prevent the agitator 8 from colliding with the bottom of the paint bucket, allowing the agitator 8 to rotate undisturbed and positioned above the paint at the bottom of the bucket. This allows the agitator 8 to move the paint at the bottom of the bucket upwards and mix it evenly with the paint above. This overall design constitutes a protective component to prevent the agitator 8 from touching the bottom or the wall. Alternatively, the protective component can be a cylindrical wire mesh, which is placed over the agitator 8 and fixed to the outer wall of the connecting cover 1. The wire mesh protects the agitator 8 and prevents it from touching the bottom or the wall.

[0028] In actual use, the end of the suction pipe is inserted into the connecting cover 1, and the screw is turned to fix the connecting cover 1 to the end of the suction pipe. The connecting cover 1 is then placed in the paint bucket, and the main body 10 is opened, so that the end of the suction pipe generates suction. The paint in the paint bucket is sucked into the connecting cover 1 from the inlet. When the paint passes through the water wheel 4, it will push it to rotate. The water wheel 4 will drive the stirring wheel 8 to rotate through the rotating shaft 9. During the rotation, all the stirring plates on the stirring wheel 8 will stir the paint in the paint bucket and drive the paint at the bottom of the bucket to move upward, so that the paint at the top and bottom of the paint bucket is mixed, thereby preventing the components in the paint from settling at the bottom of the bucket and making the paint components in the bucket more uniform.
