Description

Technical Field

[0001] The invention belongs to the technical field of paint roller cleaning tools, in particular to a paint roller cleaning tool. Background Art

[0002] A paint roller brush, also known as a roller brush or a paint brush, is an important tool for rolling paint on a large area. The paint roller brush is mainly composed of a rod-shaped handle and a paint roller rotatably arranged on the rod-shaped handle. The paint roller is used to dip in paint and then brush it.

[0003] The paint roller brush needs to be cleaned after use, otherwise the paint cannot be used again after solidification. The existing paint roller is generally fixed to the handle, and it is very troublesome to clean the roller. It can only be cleaned by rinsing or manually turning the roller, and it is difficult to clean it thoroughly.

[0004] CN216419918U discloses a paint roller cleaning device, comprising a gripping rod, wherein a short shaft is rotatably connected inside the gripping rod, a clamping member located at the bottom of the gripping rod is fixedly connected at the bottom of the short shaft, a clamping member is arranged outside the clamping member, a cylindrical shell located inside the gripping rod is fixedly connected at the top of the short shaft, a sliding hole is provided at the top of the cylindrical shell, a slider is movably connected inside the cylindrical shell, a spiral rod adapted to the sliding hole and extending to the top of the gripping rod is rotatably connected inside the slider, and a spring is movably connected at the top of the slider. The paint roller cleaning device clamps and fixes the handle of the paint brush through the cooperation of the clamping member and the clamping member, the gripping rod is held, the brush part of the paint brush is immersed in water, and the spiral rod is pulled to squeeze the slide, so that the cylindrical shell drives the short shaft to rotate, and the short shaft drives the paint brush indirectly connected thereto to rotate rapidly, and the brush part of the paint brush rotates rapidly in the water, so that the paint on the paint brush quickly dissolves into the water, thereby achieving the purpose of high cleaning efficiency.

[0005] When the paint roller cleaning device clamps the paint roller brush for cleaning, the paint roller brush is generally clamped with a mounting clip and placed in a bucket for cleaning. The mounting and clamping is troublesome, and the paint roller brush is easily detached during the rotation process. In addition, since the paint will dissolve in the water during the cleaning rotation process, a large amount of paint will be mixed into the water near the paint roller brush. The paint needs time to diffuse into the surrounding water, resulting in a long cleaning process and insufficient cleaning. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a paint roller cleaning tool, which can conveniently clamp the paint roller and can suck water around the paint roller and discharge it outside the bucket or to a position away from the paint roller, thereby effectively improving the cleaning efficiency and making the paint roller cleaner.

[0007] In order to solve the above technical problems, the present invention is solved by the following technical solutions: a paint roller cleaning tool, comprising a fixed cylinder, a rotating cylinder rotatably connected to the fixed cylinder, and a positioning head fixed to the bottom of the rotating cylinder, wherein a rotating drive assembly for rotating the rotating cylinder is arranged inside the fixed cylinder, the positioning head comprises a plurality of elastic arms arranged around a circumference, a movable channel is formed inside the elastic arms, a movable block is arranged in the movable channel, the bottom of the elastic arm is bent inwardly to limit the movable block, a water passage is arranged between the elastic arms and / or on the movable block, a reset spring is arranged between the bottom of the rotating cylinder and the movable block, a plurality of guide cylinders are radially extended from the side wall of the rotating cylinder, a counterweight piston is movably arranged in the guide cylinder, the counterweight piston is connected to the movable block by a cable passing through the bottom of the rotating cylinder, a water storage chamber connected to the guide cylinder is arranged in the rotating cylinder, the bottom of the water storage chamber has a one-way water inlet connected to the movable channel, and a one-way water outlet is arranged on the side of the water storage chamber. When the paint roller cleaning tool needs to clean the paint roller brush, the paint roller on the paint roller brush is first removed, the paint roller is placed on the elastic arm to position it, and then one end of the positioned paint roller is immersed in water, with the one-way water outlet located outside the water surface. The rotating drum is then driven to rotate by the rotating drive assembly, and the rotating drum is cleaned during the rotation. When the rotating drum rotates, due to the centrifugal force, the counterweight piston moves outward to form a suction force, and the water close to the paint roller is sucked into the water storage chamber from the water outlet through the one-way water inlet. When the rotating drum stops, the counterweight piston is pulled back due to the elastic force of the return spring, and the water in the water storage chamber is squeezed out of the one-way water outlet to the outside of the water bucket or to a position away from the periphery of the paint roller, so that the water on the cleaning side of the paint roller can be kept relatively clean and contains less paint, thereby effectively improving the cleaning efficiency and making the paint roller cleaner.

[0011] In the above technical solution, preferably, the movable channel is larger at the bottom and larger at the top, and the movable block is an elastic wedge-shaped block that is larger at the bottom and smaller at the top. With this structure, during the rotation of the rotating drum, the elastic wedge-shaped block rises to provide a certain force to bounce the elastic arm outward, thereby further increasing the friction between the elastic arm and the inner wall of the paint roller, preventing the paint roller from slipping off the elastic arm.

[0012] In the above technical solution, preferably, the rotation drive assembly includes an insertion rod and a sleeve, the sleeve is rotatably connected to the fixed cylinder, the insertion rod is movably inserted in the sleeve, the inner wall of the sleeve is provided with a spiral groove, the outer wall of the insertion rod is provided with a protrusion that cooperates with the spiral groove for movably limiting, and the bottom of the sleeve is fixed with the rotating cylinder. With this structure, the sleeve can be rotated by pushing and pulling the insertion rod up and down through the cooperation of the protrusion and the spiral groove, and the sleeve drives the rotating cylinder to rotate.

With this structure, the sleeve can be rotated by pushing and pulling the insertion rod up and down through the cooperation of the protrusion and the spiral groove, and the sleeve drives the planetary disk to rotate, and the rotation speed of the rotating cylinder is further increased through the planetary gear structure, thereby improving the cleaning effect.

[0014] In the above technical solution, preferably, a handle is fixed on the top of the insertion rod. This structure makes it convenient to push and pull the insertion rod.

[0015] In the above technical solution, preferably, a positioning rod is radially extended from one side of the insertion rod near the top, and an annular groove with a notch at the top is provided at the top of the fixing tube, and the positioning rod can be inserted into the annular groove to position the insertion rod in the fixing tube. With this structure, when it is needed, the insertion rod can be rotated to a position where the positioning rod is aligned with the notch, so that the insertion rod can be pushed and pulled, and when it is not needed, the positioning rod can be inserted into the annular groove, the insertion rod will not be pulled out, and the entire paint roller cleaning tool can be conveniently moved by holding the handle.

[0016] Compared with the prior art, the present invention has the following beneficial effects: when the paint roller cleaning tool needs to clean the paint roller brush, the paint roller on the paint roller brush is first removed, the paint roller is placed on the elastic arm to be positioned, and then one end of the positioned paint roller is immersed in water, with the one-way water outlet located outside the water surface, and then the rotating drum is driven to rotate by the rotating drive assembly, and the rotating drum is cleaned during the rotation process. When the rotating drum rotates, due to the action of centrifugal force, the counterweight piston moves outward to form a suction force, and the water close to the paint roller is sucked into the water storage chamber from the one-way water inlet. When the rotating drum stops, due to the elastic force of the return spring, the counterweight piston is pulled back, and the water in the water storage chamber is squeezed out of the one-way water outlet to the outside of the water bucket or to a position away from the periphery of the paint roller, so that the water on the cleaning side of the paint roller can be kept relatively clean and contain less paint, thereby effectively improving the cleaning efficiency and making the paint roller cleaner.
