Description

Technical Field

[0001] The utility model relates to a brush head of a fabric cleaning machine, belonging to the field of fabric cleaning machines. Background Art

[0002] A fabric cleaning machine is an electrical appliance designed specifically for cleaning soft textiles such as fabric furniture, curtains, and carpets. The brush head is one of the main components of a fabric cleaning machine. A bristle brush head is installed in a brush head cover. The brush head plate on the brush head is connected to the brush head cover to facilitate replacement when the bristles are worn. That is, a clamping hole is opened on the surface of the brush head cover, and an elastic plate with a semicircular head is installed on the brush head plate. The elastic plate is usually made of thin plastic, and the elastic plate and the brush plate are an integrally molded structure. Therefore, when the semicircular head is clamped in the clamping hole, the elastic plate may break due to bending, resulting in the unused bristle brush head being discarded. Therefore, it is necessary to design a brush head for a fabric cleaning machine in which the part of the brush head plate that is connected to the brush head cover can be replaced separately.
