Dual-function floor cleaning brush

Abstract

A dual-function floor cleaning brush comprises a crevice brush with a threaded head at the top for handle connection and a floor brush with an interior connection groove for crevice brush embedment, allowing a combination into a single entity. The top of the floor brush is movably provided with a fixing knob for clamping the crevice brush, the positioning slots are provided on both sides of the crevice brush, and positioning blocks are provided on both sides of the inner wall of the connection groove, realizing engagement between the positioning slots and the positioning blocks with the crevice brush embedded into the connection groove. The crevice brush and floor brush can be used independently or in combination, and rotating the fixing knob realizes a simple and quick operation of installing and removing the crevice brush, enabling the threaded head's angle adjustment via the turning knob.
