Description

Technical Field

[0001] This invention belongs to the field of floor brush technology, and particularly relates to a floor brush with replaceable and adjustable comb teeth. Background Technology

[0002] Floor cleaning equipment (such as vacuum cleaners, sweepers, and floor scrubbers) generally uses rotating roller brushes to achieve floor cleaning functions. However, current floor brush housings have roller brushes and drive motors installed inside, and bristles are set on the surface of the roller brush to sweep up dust and particles.

[0003] However, existing roller brushes often use a single soft or hard bristle, which makes it difficult to achieve both deep cleaning of carpets and floor protection. They are also not good at combing long hair and pet hair. In addition, the top cover and shell are often fixed with complex buckles or a large number of screws, making disassembly and assembly inconvenient. Users cannot replace the comb teeth or clean the roller brush themselves. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing roller brushes that often use only soft or hard bristles, making it difficult to achieve both deep cleaning of carpets and floor protection, and that are insufficient in their ability to comb long hair and pet hair. Furthermore, the top cover and housing are often fixed with complex snaps or a large number of screws, making disassembly and assembly inconvenient and making it difficult for users to replace the comb teeth or clean the roller brush themselves. Therefore, this invention proposes a floor brush with replaceable and adjustable comb teeth.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a floor brush with replaceable and adjustable comb teeth, comprising:

[0006] The floor brush housing has a motor slot and a roller brush slot inside. The motor is installed in the motor slot and the roller brush is installed in the roller brush slot. The roller brush is provided with soft bristles and hard bristles are provided around the soft bristles.

[0007] A detachable comb tooth assembly is located at the rear of the roller brush;

[0008] The top cover and the detachable comb assembly are detachably connected to the bottom of the top cover, which is fixed to the brush housing by adjusting screws.

[0009] Furthermore, the motor is equipped with a drive gear, and the roller brush is equipped with a driven gear. The drive gear and the driven gear are connected by a synchronous belt.

[0010] Furthermore, the aforementioned hard bristles are arranged in a V-shape around the soft bristles.

[0011] Furthermore, the aforementioned detachable comb assembly includes a comb body, a spring cover, and a positioning cover. The comb body is provided with a limiting groove, the positioning cover is fixed to the rear side of the comb body by screws, the spring cover is located in the limiting groove, and a spring is provided between the spring cover and the positioning cover.

[0012] Furthermore, the top cover is provided with a positioning groove, and the top of the spring cover abuts against the positioning groove.

[0013] Furthermore, the comb body is provided with several slots, and the top cover is provided with several blocks, with the blocks correspondingly engaging in the slots.

[0014] Furthermore, the brush housing is provided with several connecting posts, and the top cover is provided with several connecting ears. The height of the comb teeth can be controlled by adjusting the depth of the adjusting screws screwed into the connecting posts through the connecting ears.

[0015] Furthermore, the aforementioned floor brush housing is provided with a side cover, the side cover is provided with a connecting groove, and the top cover is provided with a connecting block, which is correspondingly engaged in the connecting groove.

[0016] This invention provides a floor brush with replaceable and adjustable comb teeth. It features hard bristles surrounding soft bristles and a height-adjustable, detachable comb tooth assembly at the rear of the roller brush. When in use, the motor operates, driving a gear that rotates a synchronous belt. The driven gear then drives the roller brush to rotate at high speed. The V-shaped arrangement of the hard bristles around the soft bristles enhances the brushing and combing of carpet fibers, guiding hair towards the center of the roller brush. Suitable for various floor cleaning applications, the detachable comb tooth assembly is located at the rear of the roller brush, with the comb teeth inserted into the brush. The bristle gap continuously scrapes away tangled hair during the rotation of the roller brush, detaching it from the roller brush and drawing it into the air duct. By adjusting the depth of the adjusting screw screw into the connecting post of the floor brush housing, the relative position of the top cover and the floor brush housing is changed, thereby driving the comb body to rise and fall as a whole, achieving precise control of the gap between the comb teeth and the roller brush. The spring cover is always pressed against the positioning groove of the top cover under the action of the spring, keeping the comb body stable during operation and providing a certain degree of cushioning to avoid hard impacts. This structure allows for the detachable comb tooth assembly to be easily disassembled and cleaned, greatly improving the user experience.

[0017] Therefore, this embodiment has the following advantages compared to the prior art:

[0018] A floor brush with replaceable and adjustable bristles solves the problems of existing roller brushes that often use a single soft or hard bristle, making it difficult to achieve both deep cleaning of carpets and floor protection, and that are not good at combing long hair and pet hair. In addition, the top cover and shell are often fixed with complex buckles or a large number of screws, making disassembly and assembly inconvenient, and users cannot replace the bristles or clean the roller brush themselves.
