Cleaning device for floor surface

Abstract

The invention discloses a cleaning device for the floor surface. The cleaning device comprises a car body, a cover body, an air injection assembly, a liquid spraying assembly and a brush assembly, wherein the car body comprises a chassis and a wheel. The wheel comprises a center shaft and spokes, the spokes are of a bent rod-shaped structure, the first ends of the spokes are fixed to the center shaft, the second ends are radiated outwards, a suction cup is fixed to the second of each spoke, a screw hole is formed in the center of the chassis, and a screw is matched with the screw hole; the upper end of the cover body is fixed to the screw, an opening in the lower end of the cover body is close to the floor surface, and a containing space is formed inside the cover body; the air injection assembly comprises an air pump and an air tap, the air tap is arranged inside the containing space, one end of the air tap is inclined downwards to point the floor, and the air pump is communicated with the air tap; the liquid spraying assembly comprises a hydraulic pump and a nozzle, the nozzle is arranged inside the containing space, one end of the nozzle is inclined downwards to point the floor,the hydraulic pump is communicated with the nozzle, and a liquid storage tank arranged on the chassis is communicated with the hydraulic pump; the air tap and the nozzle are arranged in a spaced mode; the brush assembly is arranged between the air tap and the nozzle.

Description

technical field [0001] The present invention relates to the technical field of cleaning equipment, more specifically, the present invention relates to a cleaning equipment for floor surface. Background technique [0002] There are horizontal and vertical splicing gaps on the surface of the wooden floor or tile floor. It is difficult for brooms, mops and conventional vacuum cleaners to clean the dust from these small gaps. As time goes by, the dust accumulates more and more, and finally accumulates and condenses into a stubborn structure. [0003] Existing floor gap cleaners usually use air force to remove impurities in the gaps. Although they have achieved certain results, they have the following problems: First, the dust forms a hard plate structure in the process of accumulating layers, while the existing The cleaner directly injects the high-pressure gas vertically on the dust, which is equivalent to directly spraying on the plane of the plate, so it is difficult to dest...
