Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a floor brush and dust collection equipment. Background Art

[0002] During the use of the vacuum cleaner floor brush, hair is easily entangled on the roller brush body. In order to prevent the hair from being entangled on the roller brush body, a comb tooth structure is usually used in conjunction with the roller brush body. The comb tooth structure contacts the rotating roller brush body to clean the hair entangled on the roller brush.

[0003] A patent with a publication (announcement) number of CN216797526U discloses a wind shield assembly and a vacuum cleaner, comprising: a wind shield, a wind duct is formed at the lower part, and a roller brush installation structure is arranged in the wind duct;

[0004] A comb structure, fixed to the air duct and installed parallel to the roller brush;

[0005] The correction structure is arranged in the air duct and abuts against the comb tooth surface of the comb tooth structure and / or the abutment surface between two adjacent comb teeth.

[0006] The comb tooth structure is fixed to the inner wall of the air duct by multiple screws, and includes a connecting body and a plurality of comb teeth, the ends of which are formed into a sawtooth shape, which can cut into the bristles. When encountering hair and silk fabrics, the hair and silk fabrics can be supported and separated from the bristles as the roller brush rotates; however, the comb teeth will be deformed due to force during this process.

[0007] Although the above patent records that the correction structure can be used to provide support for the connecting body or comb teeth to improve the anti-deformation ability of the comb tooth structure. However, since both the correction structure and the comb tooth structure are connected to the air duct, the strength of the air duct will inevitably be reduced, and the structure of the floor brush will be more complicated due to the addition of the correction structure. In addition, since the comb tooth structure is fixed to the inner wall of the air duct by multiple screws, the assembly steps of the floor brush will also be too complicated. Utility Model Content

[0073] Furthermore, a strip-shaped reserved area 2007 is provided at the position directly above the air inlet 2002. At the same time, the reserved area 2007 is also located above each first comb tooth 2004 and each second comb tooth 2005. The first end of the reserved area 2007 is a part of the first end of the front end plate 2001, and the second end of the reserved area 2007 is a part of the second end of the front end plate 2001. A plurality of third comb teeth 2006 are arranged from the first end of the reserved area 2007 to the second end of the reserved area 2007 at equal intervals along the axis direction of the reserved area 2007. Along the rotation direction of the roller brush body 3, each third comb tooth 2006 is located upstream of each first comb tooth 2004 and each second comb tooth 2005. Such a design enables a plurality of third comb teeth 2006 to be respectively arranged above each first comb tooth 2004, above the air inlet 2002 and above each second comb tooth 2005, so that all hairs wound around the roller brush body 3 are loosened.

[0074] Preferably, a plurality of third comb teeth 2006 are arranged along the length direction of the air inlet 2002 at equal intervals from the first end of the air inlet 2002 to the second end of the air inlet 2002, so as to be arranged in a partial area of ​​the reserved area 2007. Such a design can not only simplify the structure of the front end plate 2001, but also loosen the hair on the roller brush body 3.

[0075] More preferably, the shape of the third comb tooth 2006 is roughly similar to a triangle, and is composed of a third front end portion 20062, a third rear end portion 20063 and a first bottom portion 20064.
