Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, specifically to a detachable roller brush bristle. Background Technology

[0002] Roller brushes are cleaning tool accessories used in household appliances. As cleaning components for appliances such as vacuum cleaners and robot vacuums, roller brushes enhance cleaning effectiveness through soft tufting or bristle-forming processes and are suitable for different floor materials (such as carpets and wood floors).

[0003] However, traditional vacuum cleaner roller brushes are usually directly connected to the main unit drive shaft via end cap bearings and fixed with clips or screws. The matching bristles are mostly non-removable integral designs, or although they are detachable, the disassembly process is extremely cumbersome. In response to the above problems, the inventors have proposed a detachable roller brush bristle to solve the above problems. Utility Model Content

[0004] To address the problem that vacuum cleaner roller brushes typically use a non-detachable, one-piece design, or are detachable but the disassembly process is extremely cumbersome, the purpose of this utility model is to provide a detachable roller brush bristle.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a detachable roller brush strip, including a housing, a roller rotatably mounted inside the housing, a roller brush body detachably mounted on the outer surface of the roller, an mounting plate installed inside the housing, a collar fixedly mounted on one side of the mounting plate, the collar slidably sleeved on the outer surface of the roller, a second positioning ring rotatably mounted on one side of the collar, a second insert fixedly mounted on one side of the second positioning ring, the second insert slidably inserted into the roller brush body; a sliding plate slidably mounted inside the mounting plate, a lever fixedly mounted on one side of the sliding plate, and a fixed connection between the mounting plate and the sliding plate. A first spring is fixedly connected to the sliding plate. A fixed block is fixedly provided on one side of the sliding plate. The fixed block is slidably inserted into the housing. A first positioning ring is fixedly sleeved on the outer surface of the roller. A first insert block is fixedly provided on one side of the first positioning ring. The roller brush body is slidably inserted into the outer surface of the first insert block. First, by turning on the brushless motor and cooperating with the gear set to drive the rotation, the roller brush body is prompted to wrap the hair. The cleaning rod is located on the outside of the roller brush body. Then, when the roller brush wraps the hair, the cleaning rod is prompted to peel off the wrapped hair, and the suction of the vacuum cleaner sucks the hair into the dust collection chamber, which facilitates the cleaning of the roller brush body. By pulling the lever, the movable plate slides the cleaning rod, compressing the second spring and moving the cleaning rod away from the outer surface of the roller brush body. Then, pressing the lever causes the sliding plate to slide inside the mounting plate and compress the first spring, causing the fixing block to disengage from the housing. The mounting plate then moves the collar away from the outer surface of the roller and moves the second positioning ring away from the side of the roller brush body. At the same time, the second insert disengages from the roller brush body, thus allowing the roller brush body to be disengaged from the roller, making disassembly of the roller brush body relatively convenient.

[0006] Preferably, a connecting ring is fixedly provided on one side of the second positioning ring, the connecting ring is rotatably disposed within the collar, a limiting ring is fixedly sleeved on the outer surface of the connecting ring, a limiting groove is opened in the collar, the limiting ring is rotatably sleeved within the limiting groove, a splicing groove is opened in the housing, and splicing blocks are fixedly provided on both sides of the mounting plate, the splicing blocks are slidably inserted into the splicing groove.

[0007] Preferably, a movable plate is slidably provided inside the housing, a cleaning rod is fixedly provided on one side of the movable plate, a pull rod is fixedly provided on one side of the movable plate, a second spring is fixedly connected between the inner wall of the housing and the movable plate, an auxiliary rod is fixedly provided inside the housing, the movable plate is slidably sleeved on the outer surface of the auxiliary rod, a baffle is fixedly provided at one end of the auxiliary rod, and the movable plate can fit against one side of the baffle.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By moving the mounting plate and the collar away from the outer surface of the roller, and moving the second positioning ring away from the side of the roller brush body, while the second insert block is removed from the roller brush body, the roller brush body can be removed from the roller, which makes it easier to disassemble the roller brush body. 2. By placing the cleaning rod on the outside of the roller brush body, it causes the cleaning rod to peel off the hair that is wrapped around it when it rolls and gets tangled in the brush. The suction power of the vacuum cleaner then draws the hair into the dust collection chamber, making it easier to clean the roller brush body and increasing its usage time.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Example: Figure 1-7As shown, this utility model provides a detachable roller brush bristle, including a housing 1, a roller 11 rotatably mounted inside the housing 1, a roller brush body 12 detachably mounted on the outer surface of the roller 11, an mounting plate 2 installed inside the housing 1, a collar 26 fixedly mounted on one side of the mounting plate 2, the collar 26 slidably sleeved on the outer surface of the roller 11, a second positioning ring 29 rotatably mounted on one side of the collar 26, and a second insert 291 fixedly mounted on one side of the second positioning ring 29, the second insert 291 slidably inserted into the roller brush body 12; the mounting plate 2 slides inside the roller brush body 12. A sliding plate 21 is provided, and a lever 24 is fixedly provided on one side of the sliding plate 21. A first spring 22 is fixedly connected between the mounting plate 2 and the sliding plate 21. A fixing block 23 is fixedly provided on one side of the sliding plate 21. The fixing block 23 is slidably inserted into the housing 1. (By connecting the vacuum cleaner to an external power source and turning on the vacuum cleaner switch, the current will drive a precision-balanced motor to rotate at extremely high speed. A fan is connected to the motor shaft. As the fan rotates at high speed, it will forcefully throw air outward from the center of the fan. When the fan...) When the air at the rear is rapidly drawn away, a low-pressure area is formed inside the vacuum cleaner and in front of the fan's air intake, while the air outside the vacuum cleaner is at normal atmospheric pressure. Because the inside of the housing 1 is a low-pressure area and the outside is a high-pressure area, the outside air will rush into the housing 1. During the process of air rushing in, dust, debris, and other dirt on the floor will be carried away by the high-speed airflow and sucked into the vacuum cleaner's dust collection chamber through the housing 1, the telescopic tube, and the hose. At the same time, the roller 11 and the roller brush body 12 are driven by a brushless motor and the gear set is engaged. The drive rotates, causing the brush body 12 to wrap around the hair. By pressing the lever 24, the sliding plate 21 slides inside the mounting plate 2 and squeezes the first spring 22, causing the fixing block 23 to disengage from the housing 1. Then, the mounting plate 2 drives the collar 26 to disengage from the outer surface of the roller 11 and drives the second positioning ring 29 away from the side of the brush body 12. At the same time, the second insert 291 disengages from the brush body 12, thereby enabling the brush body 12 to be disengaged from the roller 11, which facilitates the disassembly of the brush body 12. The disassembly is relatively convenient.

[0014] A connecting ring 27 is fixedly provided on one side of the second positioning ring 29. The connecting ring 27 is rotatably disposed within the collar 26. A limiting ring 28 is fixedly sleeved on the outer surface of the connecting ring 27. A limiting groove 261 is opened in the collar 26. The limiting ring 28 is rotatably sleeved within the limiting groove 261. A splicing groove 101 is opened inside the housing 1. Splicing blocks 25 are fixedly provided on both sides of the mounting plate 2. The splicing blocks 25 are slidably inserted into the splicing groove 101. A first positioning ring 13 is fixedly sleeved on the outer surface of the roller 11. A first insert block 131 is fixedly provided on one side of the first positioning ring 13. The roller brush body 12 is slidably inserted into the outer surface of the first insert block 131.

[0015] By adopting the above technical solution, when the roller 11 and the brush body 12 are working, the roller 11 drives the first positioning ring 13 to rotate, and the first insert block 131 drives the brush body 12 to rotate. At the same time, the second positioning ring 29 drives the connecting ring 27 and the limiting ring 28 to rotate within the collar 26, thereby assisting the roller 11 and the brush body 12 to rotate so as to clean the floor.

[0016] A movable plate 32 is slidably provided inside the housing 1. A cleaning rod 35 is fixedly provided on one side of the movable plate 32. A pull rod 3 is fixedly provided on one side of the movable plate 32. A second spring 31 is fixedly connected between the inner wall of the housing 1 and the movable plate 32. An auxiliary rod 33 is fixedly provided inside the housing 1. The movable plate 32 is slidably sleeved on the outer surface of the auxiliary rod 33. A baffle 34 is fixedly provided at one end of the auxiliary rod 33, and the movable plate 32 can fit against one side of the baffle 34.

[0017] By adopting the above technical solution, the cleaning rod 35 is set in an arc shape and is located on the outside of the roller brush body 12. When the hair is rolled and wrapped around, the cleaning rod 35 is prompted to peel off the wrapped hair and the suction of the vacuum cleaner sucks the hair into the dust collection chamber, which facilitates the cleaning of the roller brush body 12 and increases the usage time. By pulling the pull rod 3, the movable plate 32 drives the cleaning rod 35 to slide and squeeze the second spring 31, so that the cleaning rod 35 moves away from the outer surface of the roller brush body 12, which facilitates the disassembly of the roller brush body 12.

[0018] Working principle: First, the brushless motor is turned on and the gear set is engaged to drive the rotation, causing the roller brush body 12 to wrap around the hair. The cleaning rod 35 is located on the outside of the roller brush body 12. When the hair is rolled and wrapped, the cleaning rod 35 is forced to peel off the wrapped hair, and the suction of the vacuum cleaner sucks the hair into the dust collection chamber, which makes it easier to clean the roller brush body 12. By pulling the lever 3, the movable plate 32 causes the cleaning rod 35 to slide and compress the second spring 31, thereby moving the cleaning rod 35 away from the outer surface of the roller brush body 12. Then, the push plate 24 is pressed, causing the sliding plate 21 to slide inside the mounting plate 2 and compress the first spring 22, causing the fixing block 23 to disengage from the housing 1. Then, the mounting plate 2 causes the collar 26 to disengage from the outer surface of the roller 11 and causes the second positioning ring 29 to move away from the side of the roller brush body 12. At the same time, the second insert 291 disengages from the roller brush body 12, thereby enabling the roller brush body 12 to be disengaged from the roller 11, which facilitates the disassembly of the roller brush body 12. The disassembly is relatively convenient.
