Description

Cleaning head device and cleaning equipment

Technical Field

The disclosure belongs to the technical field of cleaning equipment, and particularly relates to a cleaning head device and cleaning equipment.

Background

Surface cleaning devices of the prior art, for example for wet cleaning of hard floors or short-hair carpets, usually have one or more roller brushes or cleaning discs made of a woollen material, which can scrub stubborn dirt on the floor by adding water or a water/detergent mixture.

When the machine moves over the dirt, the dirt that has been wiped off by the roller brush and dissolved by the water or water/detergent mixture is sucked up with the cleaning head arranged in the direction of movement of the roller brush, and in the technique of providing the cleaning tray, the cleaning head may not be provided and the dirt is directly adsorbed by the cleaning material on the cleaning tray. Scrubbing is a cleaning process that removes stains that adhere to the surface of a floor.

In the prior art, nozzles distributed along the circumferential direction of a rolling brush are generally arranged on a cleaning head, certain pressure is applied to fluid and the fluid is sprayed onto the rolling brush in front of the nozzles, so that a wet surface is formed on the surface of the rolling brush, and dirt and dust are removed by the friction between the wet surface and the ground.

In order to improve the cleaning quality, cleaning is usually performed by mixing a cleaning agent and water, the cleaning agent and the water are mixed in a clean water tank of the surface cleaning device according to a certain proportion to form a cleaning fluid, and then the cleaning fluid is applied to a rolling brush or a cleaning disc to achieve a good cleaning effect of stubborn stains.

However, most surface cleaning devices of the prior art spray water onto the brush bristles unevenly due to pressure dissipation towards the distal end of the water inlet, so that an uneven distribution of liquid is formed on the brush, i.e. more liquid at the brush close to the water inlet and less liquid at the brush far from the water inlet, so that at the beginning of the cleaning process coarse and fine water spots appear on the cleaning surface, which is an undesired result for the "line cleaning" intended to achieve "surface cleaning", and a technique is needed to solve the above-mentioned problems.
