Description

Technical Field

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

[0002] Floor brushes are common accessories for vacuum cleaners, sweepers, and floor scrubbers. The rolling motion of the floor brush improves the cleaning effect. The roller, as the moving cleaning structure inside the floor brush, assists in cleaning impurities on the floor. However, current floor brushes are prone to getting tangled with hair during use, increasing the difficulty of subsequent cleaning.

[0003] The prior art (Chinese patent publication number CN218832653U, published on April 11, 2023) describes a self-cleaning, cutting, and entanglement-removing floor brush, belonging to the field of floor brush technology. It includes a floor brush body, a driver, a cleaning roller, and a toothed roller. Both the cleaning roller and the toothed roller are hinged inside the floor brush body, with the cleaning roller protruding from the bottom of the brush body. The cleaning roller and the toothed roller are connected by a speed-changing mechanism, and the toothed roller contacts the surface of the cleaning roller. This invention achieves automatic cleaning of entangled hair and other adhering substances on the roller by simultaneously rotating the cleaning roller and the toothed roller. The cleaning roller cleans the floor, while the toothed roller combs and cuts away lint or debris on the surface of the cleaning roller. This ensures normal rotation of the cleaning roller, prevents air inlet blockage, maintains good cleaning performance, and avoids increased energy consumption.

[0004] While some floor brush rollers currently available have hair-cutting and anti-tangling functions, allowing hair to be supported by the bristles on the roller after it gets tangled, the blades are effective at cutting hair near the bristles. However, hair further away from the bristles collapses onto the roller surface due to lack of support, preventing the blades from effectively contacting it. Furthermore, the random placement of floor brushes can result in insufficient hair cutting, and the bristles are prone to contact with the blades after placement, which can damage the bristles. Utility Model Content

[0005] The purpose of this utility model is to provide a cleaning roller to solve the problems mentioned in the background art. Although some existing floor brush rollers have the function of cutting and preventing hair from getting tangled, and the hair can be supported by the bristles on the roller after it gets tangled in the roller, the blade has a good cutting effect on the hair near the bristles during cutting. However, the hair far away from the bristles will collapse on the surface of the roller due to lack of support. The blade cannot effectively contact the hair during cutting. Furthermore, due to the randomness of the placement of the floor brush, the hair cannot be cut sufficiently. Also, the bristles are prone to come into contact with the blade after placement, and the blade cutting the bristles will damage the bristles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cleaning roller, comprising a central column and end connectors, wherein the end connectors are installed on the left and right sides of the central column to connect the central column and external equipment, wherein the surface of the central column is provided with a hair support mechanism, and the side surface of the hair support mechanism is designed with an arc shape, and the blade moves along the hair support mechanism to cut the hair wrapped on the central column.

[0007] To further optimize this technical solution, the hair support mechanism is composed of spiral ribs. The spiral ribs are fixed in a spiral shape on the surface of the central column and have a raised structure design. The spiral ribs are distributed in a spiral shape on the central column.

[0008] To further optimize this technical solution, the spiral rib body is designed in a surrounding enclosed structure, and the spiral rib body forms an installation groove inside. The installation groove is fixed and cleaned for hair implantation. The installation groove provides a protective effect for hair implantation and prevents the blade from cutting the hair implantation.

[0009] To further optimize this technical solution, the ends of the spiral ribs are designed with an enclosing inclined structure to guide the movement of the blade, and the spiral ribs are evenly distributed at equal angles on the surface of the central column.

[0010] To further optimize this technical solution, a first bracket is fixed to the left side of the central column, and a second bracket is fixed to the right side of the central column. The protruding positions of the second bracket and the first bracket are staggered from the end positions of the spiral ribs to support the hair at the ends.

[0011] To further optimize this technical solution, the surface of the spiral rib is made of polytetrafluoroethylene, which reduces the frictional resistance between the spiral rib and the blade.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The hair support structure can support the hair wrapped around the central column and suspend it, which makes it easier to cut the hair and clean it.

[0014] (2) The surrounding spiral ribs protect the cleaning hair grafts, which on the one hand does not affect the cleaning of the ground by the cleaning hair grafts, and on the other hand can prevent the blade cutting knife from damaging the cleaning hair grafts, thus extending their service life.

[0015] (3) The spiral ribs can guide the movement of the blade. After the blade contacts the spiral ribs, it can push the central column to rotate. At the same time, the blade will fit the spiral ribs to cut the hair, so that the cutting position of the hair is at the highest point of the suspension, ensuring the cutting effect.

[0020] 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.

[0021] Please see Figures 1-3 The present invention provides the following technical solution: a cleaning roller, comprising a central column 1 and an end connector 2, wherein the end connector 2 is installed on the left and right sides of the central column 1 to connect the central column 1 to external equipment;

[0022] Example 1: This example provides the following technical solution, which discloses that the surface of the central column 1 is provided with a hair support mechanism, and the side surface of the hair support mechanism is designed with an arc shape. The blade moves along the hair support mechanism to cut the hair wrapped on the central column 1.

[0023] The hair support mechanism set on the central column 1 supports the hair wrapped around the central column 1, keeping it suspended in the air, providing cutting space for the blade, so that the hair wrapped around the central column 1 can be effectively cut in the future.

[0024] Example 2: Based on Example 1, a hair support mechanism is disclosed, which is composed of a spiral rib 5. The spiral rib 5 is fixed to the surface of the central column 1 in a spiral shape and has a raised structure design. The spiral rib 5 is distributed in a spiral shape on the central column 1. The spiral rib 5 has a surrounding and enclosing structure design, and the spiral rib 5 encircles the interior to form an installation groove 6. The interior of the installation groove 6 is fixed and cleans the hair implant 7. The installation groove 6 provides a protective effect for the clean hair implant 7 and prevents the blade from cutting the clean hair implant 7. The end of the spiral rib 5 has an enclosing inclined structure design to guide the movement of the blade. The spiral rib 5 is evenly distributed at equal angles on the surface of the central column 1.

[0025] The spiral rib 5 protects the cleaning tuft 7. The left end of the spiral rib 5 is enclosed and inclined, so that after the roller is placed on the equipment, the blade will not directly contact the cleaning tuft 7 regardless of the position of the central column 1. When the blade moves horizontally to cut the hair, the blade will contact the surface of the spiral rib 5 during the movement, so that it can fully cut the hair. After the blade is in contact with the spiral rib 5, the blade continues to move, which can push the spiral rib 5 to drive the central column 1 to rotate, so that the blade can maintain contact with the spiral rib 5, thereby ensuring the cutting effect of the hair and not cutting the cleaning tuft 7.

[0026] Example 3: Based on Example 1, a first bracket 3 is fixed to the left side of the central column 1 and a second bracket 4 is fixed to the right side of the central column 1. The protruding positions of the second bracket 4 and the first bracket 3 are staggered from the end positions of the spiral rib 5 to support the hair at the end. The surface of the spiral rib 5 is made of polytetrafluoroethylene to reduce the frictional resistance between the spiral rib 5 and the blade.

[0027] The first bracket 3 and the second bracket 4 can provide support for the hair located at the end of the central column 1, so that the hair at the end can also be cut, improving the overall cutting effect of the hair. In addition, the surface of the spiral rib 5 is made of polytetrafluoroethylene, which also reduces the frictional resistance between the blade and the spiral rib 5, allowing the blade to more easily push the central column 1 to rotate through the spiral rib 5.

[0028] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
