Description

Technical Field

[0001] The utility model relates to the technical field of floor washing machines, and particularly relates to a roller brush structure and a floor washing machine. Background Art

[0002] Vacuum cleaners have become a standard tool for households to clean floors, carpets or floor tiles. The vacuum cleaner head is the most core component of the vacuum cleaner to achieve good results in various scenarios. For example, soft-bristle brushes are needed on floors, floor tiles and cement floors; on carpets, since dust is trapped in the carpet pile, using a soft-bristle brush cannot clean it thoroughly.

[0003] However, with the increase in usage time, the brush head is prone to wear, so it needs to be replaced regularly. Currently, the entire brush head is mostly completely removed and replaced; the discarded brush heads that are replaced are difficult to recycle and will have an impact on the environment. On the other hand, the cost of replacing the brush head is relatively high, and the acceptance degree of consumers is relatively low.

[0004] Therefore, in view of the deficiencies of the existing technology, it is necessary to design a roller brush structure and a floor washing machine to solve the above problems. Summary of the Utility Model

[0005] In order to overcome the above deficiencies in the existing technology, the purpose of the utility model is to provide a roller brush structure and a floor washing machine.

[0006] To achieve the above purpose and other related purposes, the technical solution provided by the utility model is: a roller brush structure, comprising:

[0007] A roller body, on the circumferential wall of which a plurality of equally-angularly arranged embedding grooves are axially opened;

[0008] A movable sleeve, which is composed of two oppositely arranged connecting plates, and a plurality of clamping plates fixedly connected between the two connecting plates and equally-angularly arranged in the circumferential direction. The two connecting plates are rotatably arranged on the two end shafts of the roller body one by one, and the plurality of clamping plates are embedded in the plurality of embedding grooves one by one and can rotate reciprocally in the circumferential direction;

[0009] A torsion spring, which is sleeved on the shaft of the roller body. The first force arm of the torsion spring abuts against the roller body, and the second force arm of the torsion spring abuts against the connecting plate;

[0010] A brush strip, which is embedded in the embedding groove and clamped and fixed by the clamping plate.

[0011] The preferred technical solution is that the counterclockwise side of the groove and the clockwise side groove wall of the clamping plate are both inclined inward from top to bottom to form a wedge-shaped groove structure; or, the clockwise side of the groove and the counterclockwise side groove wall of the clamping plate are both inclined inward from top to bottom to form a wedge-shaped groove structure.

[0012] The preferred technical solution is that an annular groove is provided at the end of the roller body, a first stop post is provided in the annular groove, a second stop post is provided on the inner side of the connecting plate, the torsion spring is arranged in the annular groove, a first force arm of the torsion spring abuts against the first stop post, and a second force arm of the torsion spring abuts against the second stop post.

[0013] The preferred technical solution is that the brush strip is composed of a base belt and bristles, the bristles are fixed on the base belt, and the base belt forms a wedge-shaped strip structure with a narrow upper part and a wide lower part in cross section.

[0014] A floor washer includes the above-mentioned roller brush structure.

[0015] Due to the application of the above technical solution, the beneficial effects of the present invention are:

[0016] A roller brush structure and a floor washer provided by the present invention form a clamping structure for detachably assembling a brush belt through the cooperation of a roller body, a movable sleeve and a torsion spring; that is, after the bristles are worn, the bristles can be replaced separately. This structure has the characteristics of convenient replacement, cost saving for replacement, environmental friendliness, etc., and is suitable for popularization and use.
