Description

Technical Field

[0001] This invention belongs to the field of decoration equipment technology, and specifically discloses a roller brush for interior decoration. Background Technology

[0002] Interior decoration encompasses room design, renovation, furniture arrangement, and various small embellishments. It emphasizes the interior construction and renovation of buildings, including not only the design and construction phases but also the ongoing decoration after occupancy. Furthermore, the concept of "light renovation, heavy decoration" should be gradually established. During home renovation, roller brushes are typically used to paint walls and ceilings.

[0003] Traditionally, interior decoration using roller brushes involved first soaking the brush in paint to coat it with paint, then pressing it firmly against the wall to begin painting. This resulted in the brush being overloaded with paint, causing it to expand outwards and drip excessively. During painting, paint easily dripped onto workers or the floor, causing pollution and waste. Furthermore, the worker pulled the roller brush downwards, limiting the area of ​​the brush that rolled on the wall. This resulted in less contact between the brush and the wall, leading to poor painting results and requiring secondary painting, thus reducing painting efficiency. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The motor drives the transmission shaft to rotate, and the transmission shaft drives the docking buckle to rotate via the slider. At the same time, the docking buckle drives the connecting buckle to rotate, and the connecting buckle drives the connecting shaft to rotate. Therefore, the connecting shaft drives the control shaft to rotate via two sets of slots and belts, and the control shaft drives the sponge roller to rotate. This causes the sponge roller to rotate inside the paint bucket, and during the rotation, the sponge roller fills itself with paint and expands outward. The sponge roller contacts the baffle, and the excess paint is squeezed off by the baffle during the rotation. This prevents the sponge roller from being overly covered with paint, thus metering the paint on the surface of the sponge roller and preventing excessive paint dripping from the surface of the sponge roller.

[0016] 2. At the same time, the motor drives the sponge roller to rotate, thus avoiding the situation where the entire sponge roller is immersed in the paint, and also avoiding the situation where the sponge roller is covered with too much paint.

[0017] 3. Furthermore, the sliding block is driven by the mating buckle to slide inside the sliding groove, thus causing the mating buckle to disengage from the connecting buckle. As a result, when the drive shaft drives the mating buckle to rotate through the sliding block, the mating buckle cannot drive the connecting buckle to rotate. Therefore, the control shaft cannot drive the sponge roller to rotate, thus stopping the sponge roller from rotating. This avoids the need for multiple motor starts and stops to control the rotation of the sponge roller, thereby preventing excessive wear on the internal coils caused by repeated motor starts and stops, and thus increasing the service life of the motor.

[0018] 4. Secondly, by attaching the sponge roller to the wall and having the baffle move the baffle bar to contact the wall with the baffle bar positioned below the sponge roller, and simultaneously having the scraper contact the wall with the scraper positioned below the baffle bar, a small amount of paint drips from the surface of the sponge roller. This causes the paint to drip onto the baffle bar and flow down the baffle bar into the inner side of the baffle, where the baffle collects the dripping paint. This prevents paint from dripping onto workers or the ground, thus avoiding pollution and waste. Therefore, by limiting the position of the baffle, different functions can be achieved by limiting the position of the baffle. Thus, the baffle can limit the paint on the sponge roller and collect dripping paint, achieving multiple functions with a single baffle component.

[0019] 5. The drive shaft drives the mating buckle to rotate via the slider, and the mating buckle drives the connecting buckle to rotate, thereby causing the control shaft to drive the sponge roller to rotate via the rotating shaft. Then, pulling the handle down causes the handle to drive the sponge roller to move downwards along the wall via the support handle and the rotating shaft. This causes the sponge roller to rotate during the movement, thus allowing more paint to be applied to the wall during rotation, avoiding insufficient contact between the sponge roller and the wall, thereby improving the application efficiency. At the same time, as the sponge roller moves downwards, the scraper moves downwards along the wall, thereby removing foreign objects from the wall, thus ensuring the smoothness of the sponge roller application.

A limiting ring 59 is fixedly installed on the side of the connecting rod 52 near the limiting ring 59. A limiting part 58 is provided on the outer side of the connecting rod 52 near the limiting ring 59.

The transmission mechanism 6 includes a housing 61 fixedly installed at the other end of the support handle 1. A control groove 62 is opened at the front end of the housing 61. A motor 63 is fixedly installed at the rear end of the support handle 1. A transmission shaft 64 is installed at one end of the motor 63. The transmission shaft 64 passes through the interior of the support handle 1 and is movably connected to the support handle 1. A connecting ring 65 is movably installed on the outer side of the transmission shaft 64. A sliding groove 66 is opened at the upper end of the transmission shaft 64. A slider 67 is slidably installed on the inner side of the sliding groove 66. A second spring 68 is movably installed on the outer side of the transmission shaft 64 near the connecting ring 65. A linkage ring 69 is movably arranged on one side of the drive shaft 64. A docking buckle 610 is movably arranged on the outer side of the drive shaft 64 near the linkage ring 69. A rotating groove 611 is opened at one end of the docking buckle 610. A rotating ring 612 is movably arranged on the inner side of the rotating groove 611. A connecting buckle 613 is engaged at the other end of the docking buckle 610. A linkage shaft 614 is fixedly arranged at the other end of the connecting buckle 613. A support frame 615 is movably arranged on the outer side of the linkage shaft 614. An adjustment frame 616 is movably arranged on the outer side of the linkage ring 69. An adjustment groove 617 is opened at the upper end of the adjustment frame 616. An adjustment rod 618 is movably arranged on the inner side of the adjustment groove 617. A push handle 619 is fixedly arranged at the front end of the adjustment frame 616.

[0036] A button 5810 is fixedly installed at the rear end of the connecting frame 584. A screw 510 is fixedly installed at the other end of the connecting rod 52. A nut 511 is installed on the outer thread of the screw 510. A docking frame 512 is fixedly installed at the upper end of the scraper 57. A threaded rod 513 is installed on the inner thread of the docking frame 512. The baffle 54 is arc-shaped. There are two sets of baffle rods 55. One end of the limiting shaft 585 is fixedly connected to one end of the support handle 1 near the side of the moving groove 7. The components include a limiting ring 581, a limiting rod 582, a connecting block 583, a connecting frame 584, a limiting shaft 585, and a movable block 5. There are two sets of each of the 86 types. One end of the movable shaft 587 is fixedly connected to one end of the movable block 586. The upper end of the first spring 589 is fixedly connected to the lower end of the movable block 586 near the outside of the telescopic rod 588. The lower end of the first spring 589 is fixedly connected to the upper end of another set of movable blocks 586 near the outside of the telescopic rod 588. There are two sets of buttons 5810 and two sets of limiting parts 58. One end of the nut 511 is movably connected to one end of the control frame 53. The threaded rod 513 extends into the interior of the connecting seat 56 and is threadedly connected to the connecting seat 56.

[0037] In use, pressing button 5810 causes button 5810 to drive connecting block 583 to rotate around limiting axis 585 via connecting bracket 584, and connecting block 583 to drive limiting ring 581 to rotate. At the same time, connecting bracket 584 compresses telescopic rod 588 via movable block 586, and movable block 586 compresses spring 589. Then, pushing baffle 54 causes baffle 54 to push connecting rod 52 to move via control bracket 53, and connecting rod 52 drives moving block 51 to slide inside moving groove 7, so that connecting rod 52 contacts another set of limiting parts 58. Therefore, the connecting rod 52 pushes the limiting ring 581 outward through the limiting rod 582, and the limiting ring 581 causes the connecting block 583 to rotate around the limiting shaft 585. At the same time, the connecting block 583 causes the connecting frame 584 to rotate, and the connecting frame 584 causes the movable block 586 to rotate through the movable shaft 587. The movable block 586 then compresses the telescopic rod 588 and the first spring 589 downward, thereby moving the connecting rod 52 to the inside of the limiting ring 581. Under the elastic action of the first spring 589, the first spring 589 pushes the movable block 586 to move in the opposite direction, thereby causing the movable block 586 to rotate. The movable block 586 drives the connecting frame 584 via the movable shaft 587, thus causing the connecting frame 584 to push the connecting block 583 to rotate in the opposite direction around the limiting shaft 585. Simultaneously, the connecting block 583 drives the limiting ring 581 to clamp the connecting rod 52, thus limiting the movement of the connecting rod 52 and consequently limiting the movement of the baffle 54. Then, the sponge roller 2 is placed against the wall, and the baffle 54 causes the stop rod 55 to contact the wall, with the stop rod 55 positioned below the sponge roller 2. At the same time, the scraper 57 contacts the wall, with the scraper 57 positioned below the stop rod 55. A small amount of paint drips onto the surface of the sponge roller 2, causing the paint to fall above the baffle 55 and flow down the baffle 55 into the inner side of the baffle 54. The baffle 54 collects the dripping paint, thus preventing paint from dripping onto workers or the ground, causing pollution and waste. The baffle 54 is limited by the limiting part 58, so the position of the baffle 54 can be limited to achieve different functions. Thus, the baffle 54 can limit the sponge roller 2 from picking up paint and collect dripping paint, achieving multiple functions with the baffle 54 as a single component.

[0038] A movable frame 620 is movably mounted on the outer side of the push handle 619 via a rotating shaft. A slot 621 is fixedly mounted on the outer side of the connecting shaft 614 near the support frame 615. A belt 622 is driven through the outer side of the slot 621. There are two sets of slots 621, and both sets of slots 621 form a transmission connection with the belt 622. A control shaft 623 is fixedly mounted on the inner side of the other set of slots 621. One end of the movable frame 620 is fixedly connected to the other end of the support handle 1 near the inner side of the outer shell 61. One end of the connecting ring 65 is fixedly connected to the other end of the support handle 1 near the rear side of the movable frame 620. The upper end of the slider 67 is connected to the inner side of the mating buckle 610. The inner side wall is fixedly connected. One end of the second spring 68 is fixedly connected to the other end of the connecting ring 65. The other end of the second spring 68 is fixedly connected to one end of the linkage ring 69. One end of the rotating ring 612 is fixedly connected to the other end of the linkage ring 69. One end of the support frame 615 is fixedly connected to the other end of the support handle 1 near the rear side of the connecting ring 65. The lower end of the adjusting rod 618 is fixedly connected to the upper end of the linkage ring 69. The outer side of the push handle 619 near the front side of the movable frame 620 is movably connected to the inner side of the control groove 62. The control shaft 623 passes through the interior of the support handle 1 near the rear side of the transmission shaft 64. The control shaft 623 is movably connected to the support handle 1.

[0039] Simultaneously, motor 63 is started, causing motor 63 to drive transmission shaft 64 to rotate. Transmission shaft 64, via slider 67, drives mating buckle 610 to rotate. Mating buckle 610 rotates around rotating ring 612 via rotating groove 611, thus driving connecting buckle 613 to rotate. Connecting buckle 613 then drives connecting shaft 614 to rotate. Connecting shaft 614, via two sets of slots 621 and belt 622, drives control shaft 623 to rotate. Control shaft 623, via rotating shaft 3, drives sponge roller 2 to rotate, causing sponge roller 2 to rotate inside paint bucket. During rotation, sponge roller 2 absorbs paint and expands outwards, contacting baffle 54, thus increasing its rotation speed. During the process, the sponge roller 2 is squeezed off by the baffle 54, thus preventing the sponge roller 2 from being overly covered with paint. This quantitatively measures the amount of paint on the surface of the sponge roller 2 and prevents excessive paint dripping. Simultaneously, the motor 63 drives the sponge roller 2 to rotate, preventing the entire sponge roller 2 from being immersed in paint for suction and avoiding excessive paint accumulation. Then, the push handle 619 is pushed, causing it to slide inside the control groove 62. The push handle 619 rotates via the movable frame 620, causing it to push the control rod 618 through the control groove 617. This causes the control rod 618 to drive the linkage ring 69 along the transmission... The moving shaft 64 moves, causing the connecting ring 69 to compress the second spring 68. Simultaneously, the connecting ring 69, through the rotating ring 612, drives the mating buckle 610 to move, causing the mating buckle 610 to drive the slider 67 to slide within the sliding groove 66. This causes the mating buckle 610 to disengage from the connecting buckle 613. Consequently, when the drive shaft 64 drives the mating buckle 610 to rotate via the slider 67, the mating buckle 610 cannot drive the connecting buckle 613 to rotate. Therefore, the control shaft 623 cannot drive the sponge roller 2 to rotate, thus stopping the sponge roller 2 from rotating. This avoids repeated starting and stopping of the motor 63 to control the rotation of the sponge roller 2, preventing excessive wear on the internal coils and extending the service life of the motor 63. Pushing handle 619 causes spring 68 to rebound outward under its elastic force, pushing linkage ring 69 to move. Linkage ring 69 then pushes control frame 616 via control rod 618, causing control frame 616 to rotate push handle 619 within movable frame 620. Simultaneously, linkage ring 69 pushes mating buckle 610 to move via rotating ring 612, bringing mating buckle 610 into contact with connecting buckle 613. This creates an engaging connection between mating buckle 610 and connecting buckle 613. Drive shaft 64, via slider 67, rotates mating buckle 610, which in turn rotates connecting buckle 613. This causes control shaft 623 to rotate sponge roller 2 via rotating shaft 3. Finally, pull handle 4 downward.Furthermore, the handle 4, through the support handle 1 and the rotating shaft 3, drives the sponge roller 2 to move downwards along the wall, causing the sponge roller 2 to rotate during this movement. This rotation ensures that more paint is applied to the wall surface, preventing insufficient contact between the sponge roller 2 and the wall, thus improving application efficiency.

[0040] The outer side of the sponge roller 2 is movably connected to the inner side of the baffle 54. A rotating shaft 3 is fixedly installed on the inner side of the sponge roller 2. One end of the rotating shaft 3 is fixedly connected to one end of the control shaft 623. A handle 4 is fixedly installed at the front end of the support handle 1. The support handle 1 is Z-shaped.

[0041] By holding the handle 4, it is easier for workers to operate.

[0042] Working principle: In use, the worker first holds the handle 4 and inserts the support handle 1 upside down into the paint bucket, so that part of the surface of the sponge roller 2 is placed in the paint, and the baffle 54 is positioned above the paint. Then, the motor (model: Y2-90L-2) 63 is started, causing the motor 63 to drive the drive shaft 64 to rotate. The drive shaft 64, through the slider 67, drives the mating buckle 610 to rotate, and the mating buckle 610 rotates around the rotating ring 612 through the rotating groove 611. This causes the mating buckle 610 to drive the connecting buckle 613 to rotate, which in turn drives the connecting shaft 614 to rotate. Simultaneously, the connecting shaft 614, through two sets of slots 621 and the belt 622, drives the control shaft 623 to rotate, thus causing the control shaft 623 to rotate through the rotating groove 611. The rotating shaft 3 drives the sponge roller 2 to rotate, causing the sponge roller 2 to rotate inside the paint bucket. During rotation, the sponge roller 2 becomes saturated with paint and expands outwards, contacting the baffle 54. This allows the baffle 54 to push off excess paint, preventing the sponge roller 2 from becoming overly coated with paint. This metering of paint on the surface of the sponge roller 2 and preventing excessive paint dripping is avoided. Simultaneously, the motor 63 drives the sponge roller 2 to rotate, preventing it from being completely submerged in paint during suction and avoiding excessive paint accumulation. Then, the push handle 619 is pushed... The push handle 619 slides within the control groove 62, and rotates via the movable frame 620. This causes the push handle 619 to push the control rod 618 through the control groove 617, which in turn moves the control rod 618 along the drive shaft 64. The control rod 618 compresses the second spring 68, and simultaneously, the control ring 69 moves the mating buckle 610 via the rotating ring 612. The mating buckle 610 then causes the slider 67 to slide within the sliding groove 66, disengaging the mating buckle 610 from the connecting buckle 613. Consequently, when the drive shaft 64 rotates the mating buckle 610 via the slider 67, the mating buckle 610 cannot rotate the connecting buckle 613, thus preventing the control shaft 623 from rotating the sponge roller 2. The rotation of the motor 63 is reversed, thus stopping the sponge roller 2 from rotating and avoiding repeated starting and stopping of the motor 63 to control the rotation of the sponge roller 2. This also avoids excessive wear on the internal coils of the motor 63 due to repeated starting and stopping, thereby increasing the service life of the motor 63. Therefore, the support handle 1 can be removed from the paint bucket, and the button 5810 is pressed again. This causes the button 5810 to drive the connecting block 583 to rotate around the limiting shaft 585 via the connecting frame 584, and causes the connecting block 583 to drive the limiting ring 581 to rotate. At the same time, the connecting frame 584 compresses the telescopic rod 588 via the movable block 586, and causes the movable block 586 to compress the first spring 589. Then, the baffle 54 is pushed, which in turn pushes the connecting rod 52 to move via the control frame 53.The connecting rod 52 causes the moving block 51 to slide inside the moving groove 7, thereby bringing the connecting rod 52 into contact with another set of limiting parts 58. This causes the connecting rod 52 to push the limiting ring 581 outward via the limiting rod 582, and the limiting ring 581 causes the connecting block 583 to rotate around the limiting shaft 585. Simultaneously, the connecting block 583 causes the connecting frame 584 to rotate, and the connecting frame 584, via the movable shaft 587, drives the movable block 586. The movable block 586 then compresses the telescopic rod 588 and the first spring 589 downward, causing the connecting rod 52 to move inside the limiting ring 581. Under the elastic action of the first spring 589, the first spring 589 pushes the movable block 586 to move in the opposite direction, thus causing the movable block 586 to move via the movable shaft 585. 7. The connecting frame 584 is driven, which in turn pushes the connecting block 583 to rotate in the opposite direction around the limiting shaft 585. At the same time, the connecting block 583 drives the limiting ring 581 to clamp the connecting rod 52, thus limiting the movement of the connecting rod 52 and consequently limiting the movement of the baffle 54. Then, the sponge roller 2 is placed against the wall, and the baffle 54 drives the stop rod 55 to contact the wall, with the stop rod 55 positioned below the sponge roller 2. Simultaneously, the scraper 57 contacts the wall, with the scraper 57 positioned below the stop rod 55. At this time, a small amount of paint drips from the surface of the sponge roller 2, causing the paint to drip onto the top of the stop rod 55 and flow down the stop rod 55 into the inner side of the baffle 54, whereby the baffle 54 collects the dripping paint. To prevent paint from dripping onto workers or the ground, causing pollution and waste, the baffle 54 is limited by the limiting part 58. By limiting the position of the baffle 54, it can perform different functions, thus limiting the paint on the sponge roller 2 and collecting dripping paint. This allows the baffle 54 to achieve multiple functions as a single component. Then, releasing the push handle 619 causes the second spring 68 to rebound outwards under its elastic force, pushing the linkage ring 69 to move. This causes the linkage ring 69 to push the control frame 616 via the control rod 618, and the control frame 616 to rotate the push handle 619 inside the movable frame 620. Simultaneously, the linkage ring 69 pushes the docking buckle 610 via the rotating ring 612. The movement causes the mating buckle 610 and connecting buckle 613 to come into contact, thus forming an engaging connection. The drive shaft 64, via the slider 67, drives the mating buckle 610 to rotate, which in turn drives the connecting buckle 613 to rotate. This causes the control shaft 623 to drive the sponge roller 2 to rotate via the rotating shaft 3. Then, pulling down the handle 4 causes the handle 4, via the support handle 1 and the rotating shaft 3, to move the sponge roller 2 downwards along the wall. This causes the sponge roller 2 to rotate during the movement, resulting in more paint being applied to the wall surface during rotation, thus avoiding insufficient contact between the sponge roller 2 and the wall and improving application efficiency. Simultaneously, as the sponge roller 2 moves downwards...Move the scraper 57 downwards along the wall to remove foreign objects, thus ensuring the smoothness of the coating applied by the sponge roller 2. When a large amount of paint adheres to the inner side of the baffle 54, unscrew the nut 511 to remove the control bracket 53 from the outside of the connecting rod 52, allowing the baffle 54 to be replaced. Then, remove a new set of baffles 54 and place the control bracket 53 on the outside of the connecting rod 52. Tighten the nut 511 to the outside of the screw 510 to complete the replacement of a new set of baffles 54, thus facilitating the replacement of the baffles 54. Furthermore, after long-term use, when the scraper 57 wears down, unscrew the threaded rod 513 and remove the scraper 57, placing a new set of scrapers 57 on the connecting seat 56. On the surface, the threaded rod 513 is screwed into the interior of the connecting seat 56 through the docking bracket 512, thereby completing the replacement of the scraper 57. Therefore, it is convenient to replace the scraper 57 along the wear path. The motor 63 drives the transmission shaft 64 to rotate, and the transmission shaft 64 drives the docking buckle 610 to rotate through the slider 67. At the same time, the docking buckle 610 drives the connecting buckle 613 to rotate, and the connecting buckle 613 drives the connecting shaft 614 to rotate. Therefore, the connecting shaft 614 drives the control shaft 623 to rotate through two sets of slots 621 and belt 622, and the control shaft 623 drives the sponge roller 2 to rotate, so that the sponge roller 2 rotates in the paint bucket, and the sponge roller 2 absorbs paint during the rotation process, and at the same time, the sponge roller 2 expands outward, and the sponge roller 2 expands outward. When the sponge roller 2 contacts the baffle 54, excess paint is squeezed off by the baffle 54 during rotation. This prevents the sponge roller 2 from being overly covered with paint, thus metering the paint on its surface and preventing excessive paint dripping. Simultaneously, the motor 63 drives the sponge roller 2 to rotate, preventing it from being completely submerged in paint and avoiding excessive paint accumulation. Furthermore, the mating buckle 610 drives the slider 67 to slide within the sliding groove 66, disengaging the mating buckle 610 from the connecting buckle 613. Therefore, when the drive shaft 64 rotates the mating buckle 610 via the slider 67, the mating buckle 610 cannot be rotated. The rotating of the connecting buckle 613 prevents the control shaft 623 from driving the sponge roller 2 to rotate, thus stopping the sponge roller 2 from rotating. This avoids repeated starting and stopping of the motor 63 to control the rotation of the sponge roller 2, thereby preventing excessive wear on the internal coils of the motor 63 and increasing its service life. Next, by attaching the sponge roller 2 to the wall and causing the baffle 54 to drive the baffle rod 55 to contact the wall, with the baffle rod 55 positioned below the sponge roller 2, and simultaneously, the scraper 57 contacting the wall, with the scraper 57 positioned below the baffle rod 55, a small amount of paint drips from the surface of the sponge roller 2. This paint drips onto the baffle rod 55 and flows down the baffle rod 55 into the inner side of the baffle 54.This allows the baffle 54 to collect dripping paint, thus preventing paint from dripping onto workers or the ground, causing pollution and waste. The baffle 54 is limited by the limiting part 58, allowing it to perform different functions by limiting its position. Therefore, the baffle 54 restricts paint from adhering to the sponge roller 2 and collects dripping paint, achieving multiple functions with a single component. Furthermore, the drive shaft 64 drives the docking buckle 610 to rotate via the slider 67, and the docking buckle 610 drives the connecting buckle 613 to rotate, thereby causing the control shaft 623 to... The rotating shaft 3 drives the sponge roller 2 to rotate, and then the handle 4 is pulled downwards, causing the handle 4 to move the sponge roller 2 downwards along the wall via the support handle 1 and the rotating shaft 3. This rotation of the sponge roller 2 ensures that more paint is applied to the wall surface, preventing insufficient contact between the sponge roller 2 and the wall, thus improving application efficiency. Simultaneously, as the sponge roller 2 moves downwards, the scraper 57 moves downwards along the wall, removing any debris and ensuring a smooth finish.
