Floor brush device and cleaning apparatus

Abstract

This invention relates to the field of home appliance technology, providing a floor brush device and cleaning equipment. The floor brush device includes: a housing, a roller brush, a wheel body, an auxiliary wheel assembly, a wringer assembly, and a switching component. The switching component is reciprocating and used to adjust the relative positions between the auxiliary wheel assembly and the roller brush, as well as between the wringer assembly and the roller brush. The auxiliary wheel assembly and the wringer assembly are relatively movable, adjusting the support height of the auxiliary wheel assembly and the distance between the wringer assembly and the roller brush to meet the needs of different working scenarios. Through the switching component, this invention allows the auxiliary wheel assembly and the wringer assembly to adjust their distances from the roller brush independently, meeting cleaning needs for different floor hardnesses. Furthermore, by setting the distance relationship between the auxiliary wheel, the roller brush, and the wheel body, it ensures that the auxiliary wheel can provide sufficient support in multiple modes, guaranteeing cleaning effectiveness.
