Description

Round brush subassembly, cleaning head device and cleaning device

Technical Field

The utility model belongs to the technical field of cleaning device, the disclosure especially relates to a round brush subassembly, cleaning head device and cleaning device.

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 surface cleaning apparatus moves over the dirt, the dirt which has been wiped off by the drum brush and dissolved by the water or the water/detergent mixture is sucked up by the cleaning heads arranged in the direction of movement of the drum brush, and in the technique of providing the cleaning tray, the dirt may be directly adsorbed by the cleaning material on the cleaning tray without providing the cleaning heads. Scrubbing is a cleaning process that removes stains that adhere to the surface of a floor.

In the prior art, nozzles distributed along the axial direction of a roller brush are generally arranged on a cleaning head, and a certain pressure is applied to fluid so that the fluid is sprayed onto the roller brush in front of the nozzles to form a wet surface on the surface of the roller brush, and the wet surface rubs against the ground to remove dirt and dust.

EP2337475B1 discloses a fluid dispensing brush assembly and a method for operating the assembly. The brush assembly has a hollow roll brush formed of a hollow cylinder. One end of the hollow roller brush is closed and the other end can be connected to a cleaning liquid supply. The cylindrical wall of the shaft of the roller brush has a plurality of rows of ribs and a plurality of apertures are arranged therebetween, and water supplied into the hollow cylinder via the water supply can be thrown outwardly through the water channels formed by adjacent ribs via the apertures distributed in the water channels.

However, because the height of burr is limited to the water storage space in the round brush is great, when the round brush high-speed operation, can not fully guarantee that the cleaning solution is abundant to throw away, and can appear the cleaning solution and stride across the burr, make the burr lose effect, thereby often hardly guarantee that the cleaning solution evenly throws away, the water stain distribution that still can appear is uneven.

In addition, in the prior art, there is a pressure dissipation towards the distal end of the water inlet, and the water on the brush bristles is not uniform, so that the liquid is unevenly distributed on the brush bristles, i.e. the brush bristles close to the water inlet have more liquid and the brush bristles far from the water inlet have less liquid, so that at the beginning of the cleaning process, coarse and fine water spots on the cleaning surface occur, which is an undesirable result for the purpose of "surface cleaning", and thus a technique for solving the above-mentioned problems is needed.
