Description

Technical Field

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

[0002] Vacuum cleaners, as an indispensable tool in modern home cleaning, have always seen technological development and innovation focused on improving cleaning efficiency and user experience. The floor brush, a crucial component of the vacuum cleaner, directly determines its floor cleaning performance. Traditional floor brushes are designed to maximize suction power and close contact with the floor, ensuring effective removal of dust, debris, and other impurities. To achieve this, floor brushes typically feature dense bristles and a design that hugs the floor. While this enhances suction, it also introduces the risk of hair entanglement. In daily use, especially in pet-owning households, pet hair is often scattered on the floor, easily becoming tangled in the brush bristles. Once tangled, the hair accumulates, forming difficult-to-remove clumps that not only affect cleaning performance but may also hinder the vacuum cleaner's operation.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0026] like Figures 1 to 5As shown, a vacuum cleaner floor brush includes an upper shell 200 with a plug-in portion 100, a lower shell 300 snapped onto the bottom of the upper shell 200, a cover plate 400 snapped onto one end of the upper shell 200, a fixing block 401 disposed on one side of the cover plate 400 and having a first assembly portion 410 and a second assembly portion 420, a plurality of first comb teeth 402 disposed on the first assembly portion 410, a plurality of second comb teeth 403 disposed on the second assembly portion 420, a mounting groove 201 disposed on one end of the upper shell 200 and having a roller brush 500, and a drive bearing 202 disposed on one side of the mounting groove 201 and plugged into the roller brush 500; wherein, the first comb teeth 402 and the second comb teeth 403 have the same shape and structure, the end of the first comb teeth 402 near the roller brush 500 is provided with a first curved surface 440, and both the first comb teeth 402 and the second comb teeth 403 have gaps with the roller brush 500. In this embodiment, the first assembly part 410 is disposed at one end of the fixing block 401, and there is a gap between two adjacent first comb teeth 402. One end of the first comb tooth 402 is formed into a hook shape. The second assembly part 420 is disposed at the other end of the fixing block 401, and there is a gap between two adjacent second comb teeth 403. Since the first comb tooth 402 and the second comb tooth 403 have the same shape and structure, one end of the second comb tooth 403 also has a first curved surface 440, which also forms a hook shape. Through the mutual cooperation of the first curved surface 440 and the gap, when the roller brush 500 rotates, the first comb tooth 402 and the second comb tooth 403 can contact the wrapped material and hook the wrapped material off the roller brush 500.

[0027] Furthermore, the axial width of the first curved surface 440 gradually decreases from the end near the roller brush 500 to the end away from the roller brush 500, so that one end of the first curved surface 440 forms a curved tip, which can further enhance the cleaning ability of the cover plate 400 on the entangled material on the roller brush 500.

[0028] Furthermore, the fixing block 401 is also provided with a third assembly part 430 having a plurality of third comb teeth 404. It should be noted that the third assembly part 430 is located between the first assembly part 410 and the second assembly part 420, and the cross-sectional shape of the third assembly part 430 is arc-shaped. The third comb teeth 404 have the same shape and structure as the first comb teeth 402. The third comb teeth 404 also have a first curved surface 440. Transition teeth 405 are also provided on both sides of the third assembly part 430. The transition teeth 405 have inclined surfaces 406. The first comb teeth 402, the second comb teeth 403, the third comb teeth 404 and the transition teeth 405 are all located on the same axis. By setting the first comb teeth 402, the second comb teeth 403 and the third comb teeth 404 to cooperate with each other, the cleaning effect of the entangled material on the roller brush 500 can be further improved. The cooperation between the transition teeth 405 and the inclined surfaces 406 can enhance the aesthetic appearance of the fixing block 401.

[0029] Furthermore, one end of the mounting groove 201 is provided with a drive cavity 203, and a drive device 204 that is mechanically connected to the drive bearing 202 is provided in the drive cavity 203. It should be noted that, in this embodiment, the drive bearing 202 is plugged into the drive device 204. The drive device 204 includes a drive motor and a drive shaft with a connecting belt. The drive motor can be connected to an external power source, and the drive motor is plugged into the drive shaft. The connecting belt connects the drive shaft and the drive bearing 202. The drive motor drives the drive shaft to rotate, so that the drive shaft drives the drive bearing 202 to rotate together through the connecting belt.

[0030] To further optimize this embodiment, the roller brush 500 is detachably connected to the drive bearing 202. In this embodiment, the roller brush 500 is a roller component. In another preferred embodiment, the user can also use a roller component with brush strips as the roller brush 500, and make the brush strips abut against the first comb tooth 402, the second comb tooth 403, and the third comb tooth 404 respectively. By rotating the roller brush 500, it is easier to scrape off the tangled material on the roller brush 500, and further improve the cleaning effect.

[0031] Furthermore, a first roller 301 is provided at one end of the lower shell 300, and a second roller 302 is provided at one end of the upper shell 200. The first roller 301 and the second roller 302 cooperate with each other to facilitate the user to push the floor brush to move in the cleaning area, making it convenient for the user to use.

[0032] Working principle: When the roller brush 500 is rotated, the first comb tooth 402, the second comb tooth 403 and the third comb tooth 404 scrape off the entangled material on the roller brush 500.
