[0027] Example 1

[0028] like Figure 1-4 As shown, a spraying device for indoor use in green building construction includes a latex paint sprayer 1, which is connected to a latex paint spray head 7 through a paint outlet hose 2, and also includes a mounting plate 24, which is sleeved on the latex paint spray head 7, and is fixedly connected to the latex paint spray head 7. An outer limiting cylinder 12 is arranged on the right side of the mounting plate 24, and a connecting ring 13 is sleeved on the outer limiting cylinder 12, and the connecting ring 13 is fixedly connected to the outer limiting cylinder 12. A plurality of connecting screws 4 are arranged on the outer limiting cylinder 12, and the plurality of connecting screws 4 are arranged in a circumferential annular array along the connecting ring 13, and the connecting screws 4 are threadedly connected to the mounting plate 24. An inner limiting cylinder 5 is arranged inside the outer limiting cylinder 12, and the inner limiting cylinder 5 is sleeved on a bearing 10, and the bearing 10 is sleeved on the latex paint spray head 7, and the inner limiting cylinder 5 is fixedly connected to the outer ring of the bearing 10, and the inner ring of the bearing 10 is fixedly connected to the latex paint spray head 7.

[0029] Working principle: When in use, start the latex paint sprayer 1, and the latex paint sprayer 1 transports the latex paint to the latex paint nozzle 7 through the paint outlet hose 2, so that the latex paint is sprayed out through the latex paint nozzle 7. When spraying latex paint, the protective cover composed of the outer limit tube 12 and the inner limit tube 5 can effectively prevent the sprayed mist latex paint from diffusing outward on the one hand, and on the other hand, can make the sprayed latex paint remaining in the air adhere to the inner wall of the inner limit tube 5, and gather at the bottom of the inner limit tube 5 to be collected, thereby effectively avoiding the waste of latex paint.

[0030] Example 2

[0031] like Figure 1-4 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that a silicone limit ring 11 is arranged on the right side of the outer limit cylinder 12, the outer limit cylinder 12 is fixedly connected to the silicone limit ring 11, the silicone limit ring 11 is sleeved on the inner limit cylinder 5, a plurality of through holes 9 are opened at the bottom of the inner limit cylinder 5, a plurality of counterweight plates 8 are arranged at the bottom of the inner limit cylinder 5, the counterweight plates 8 are arranged in a circular array along the circumference of the inner limit cylinder 5, and a plurality of seepage holes are opened on the counterweight plates 8.

[0032] A plurality of guide rings 16 are arranged inside the outer limiting cylinder 12, and the guide rings 16 are fixedly connected to the inner wall of the outer limiting cylinder 12. A plurality of rollers 14 are arranged between the outer limiting cylinder 12 and the inner limiting cylinder 5, and the plurality of rollers 14 are arranged in an annular array along the circumference of the outer limiting cylinder 12. A slide groove is provided on the surface of the roller 14 along the circumference of the roller 14, and the guide rings 16 are located in the slide groove. A plurality of silicone protrusions are arranged on the surface of the roller 14, and the roller 14 is fixedly connected to the silicone protrusions. A plurality of roller limiting mechanisms are arranged on the inner wall of the outer limiting cylinder 12, and the plurality of roller limiting mechanisms are arranged in an annular array along the circumference of the outer limiting cylinder 12, and the number of roller limiting mechanisms is the same as that of the rollers 14. The roller limiting mechanism includes a limiting groove 18, which is provided on the inner wall of the outer limiting cylinder 12. A triangular limiting block 15 is provided inside the limiting groove 18. A buffer spring 19 is also provided inside the limiting groove 18. The top of the buffer spring 19 is fixedly connected to the bottom of the triangular limiting block 15, and the bottom of the buffer spring 19 is fixedly connected to the bottom of the limiting groove 18. A rotating shaft 21 is provided on the right side of the triangular limiting block 15. The rotating shaft 21 passes through the triangular limiting block 15, and the rotating shaft 21 is rotatably connected to the triangular limiting block 15. The end of the rotating shaft 21 is fixedly connected to the inner wall of the limiting groove 18. Guide rods 20 are provided on both the front and rear sides of the triangular limiting block 15, and the guide rods 20 are fixedly connected to the triangular limiting block 15. Arc-shaped guide grooves 17 are provided on both the front and rear sides of the inner wall of the limiting groove 18, and the guide rods 20 are located in the arc-shaped guide grooves 17. A positioning rod 3 is provided on the top of the mounting plate 24, and the positioning rod 3 is fixedly connected to the mounting plate 24.

[0033] When holding the latex paint nozzle 7 to spray latex paint, it should be ensured that the positioning rod 3 is always at the top, and the sprayed mist latex paint partially floats into the air, adheres to the inner wall of the inner limit tube 5, and then rolls along the inner wall of the inner limit tube 5 to the bottom of the inner limit tube 5, and enters through the through hole 9 between the bottom of the outer limit tube 12 and the bottom of the inner limit tube 5 to be stored.

[0034] Due to the shaking of the hand when the handheld latex paint spray nozzle 7 sprays latex paint, the latex paint spray nozzle 7 is not stable. Figure 2 As shown, when the latex paint spray head 7 shakes clockwise, the latex paint spray head 7 drives the outer limit cylinder 12 to shake synchronously clockwise through the mounting plate 24. Since a plurality of counterweight plates 8 are arranged at the bottom of the inner limit cylinder 5, the latex paint spray head 7 is connected to the inner limit cylinder 5 through the bearing 10. Under the gravity of the counterweight plate 8, the position of the inner limit cylinder 5 remains unchanged. At this time, the clockwise rotating outer limit cylinder 12 drives the roller 14 to roll clockwise along the circumference of the outer limit cylinder 12. The roller 14 stores the space between the bottom of the outer limit cylinder 12 and the inner limit cylinder 5. The latex paint at the bottom of the outer limiting cylinder 12 is pushed outward, so that there is no latex paint in the space between the bottom of the outer limiting cylinder 12 and the bottom of the inner limiting cylinder 5. On the one hand, the latex paint at the bottom of the inner limiting cylinder 5 can continue to flow into the space between the bottom of the outer limiting cylinder 12 and the bottom of the inner limiting cylinder 5 through the through hole 9. On the other hand, the latex paint between the bottom of the outer limiting cylinder 12 and the bottom of the inner limiting cylinder 5 can be pushed to other areas between the outer limiting cylinder 12 and the inner limiting cylinder 5, so as to make full use of the space between the outer limiting cylinder 12 and the inner limiting cylinder 5 to store the latex paint.

[0035] The outer limiting cylinder 12 rotates clockwise to drive the roller 14 to roll clockwise along the circumference of the outer limiting cylinder 12. Figure 3 and Figure 4 The roller 14 contacts the inclined surface of the triangular limiting block 15 , and the triangular limiting block 15 is pressed into the limiting groove 18 , thereby not affecting the rolling of the roller 14 .

[0036] like Figure 2 As shown, when the latex paint spray head 7 shakes counterclockwise, the latex paint spray head 7 drives the outer limit cylinder 12 to shake counterclockwise synchronously through the mounting plate 24. Under the gravity of the counterweight plate 8, the position of the inner limit cylinder 5 remains unchanged. At this time, the counterclockwise rotating outer limit cylinder 12 drives the roller 14 to roll counterclockwise along the circumference of the outer limit cylinder 12. However, since the roller 14 will contact the vertical surface of the triangular limit block 15, the roller 14 is resisted by the triangular limit block 15. At this time, the roller 14 does not move, the outer limit cylinder 12 slides relative to the surface of the roller 14, and the outer limit cylinder 12 is reset.

[0037] In this way, the latex paint spray head 7 shakes counterclockwise and clockwise, which will cause the roller 14 to move in a directional manner, thereby pushing the latex paint between the bottom of the outer limit cylinder 12 and the bottom of the inner limit cylinder 5 to other areas between the outer limit cylinder 12 and the inner limit cylinder 5, so as to fully utilize the space between the outer limit cylinder 12 and the inner limit cylinder 5 to store latex paint.

[0038] Example 3

[0039] like Figure 1-4 As shown, when other parts are the same as those of Example 2, the difference between this embodiment and Example 2 is that a limit stop ring 6 is provided on the right side of the inner limit cylinder 5, and the inner limit cylinder 5 is fixedly connected to the limit stop ring 6. By providing the limit stop ring 6, the latex paint in the inner limit cylinder 5 can be prevented from flowing out.

[0040] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
