Description

Scrubbing brush subassembly and surface cleaning equipment

Technical Field

The utility model belongs to the technical field of clean, this disclosure especially relates to a ground brush subassembly and surface cleaning equipment.

Background

Existing floor cleaners clean a floor with a high flow of cleaning liquid in a manner that enables complete wetting of the floor to be cleaned. By wetting the hard floor surface, the cleaning head transfers dust from the floor to the cleaning liquid, which is then removed from the hard floor surface and held in the recovery tank as contaminated cleaning liquid.

Wet surface cleaners generally comprise: a supply tank containing a cleaning solution; a recovery tank for recovering contaminants recovered from the cleaned floor; a motor driven vacuum source to create an evacuated flow path from the floor being cleaned to the recovery tank; a rechargeable battery to provide power to the components; a base station for charging and post-cleaning maintenance of the wet surface cleaner.

Efforts have been made to improve the cleaning function of wet surface cleaning devices to cope with harsh environments.

For example, patent application PCT/CN2022/087954 describes a cleaning device control method and cleaning device having a built-in thermal medium storage chamber for enhancing the cleaning ability of hard stains on a floor by applying a heated cleaning solution to the surface to be cleaned.

However, since the adhesion degree of dirt on the floor surface is different, the cleaning solution of the cleaner for cleaning a hard floor surface in the related art needs a high volume to perform the cleaning treatment of dirt for a predetermined work a plurality of times and to refill the cleaning solution, so that the interruption time of the cleaning work becomes long. Wherein refilling typically comprises filling the solution tank by hand and additionally, in order to further enhance the cleaning effect, a step of mixing with a cleaning agent or a chemical agent to form a cleaning solution is added. Mixing the cleaning solution by hand takes time and can lead to errors in the level detection of the supply tank or the recovery tank.

Accordingly, unless otherwise indicated, features of the various embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concept of the present disclosure.

The use of cross-hatching and/or shading in the drawings is generally used to clarify the boundaries between adjacent components. As such, unless otherwise noted, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for a particular material, material property, size, proportion, commonality between the illustrated components and/or any other characteristic, attribute, property, etc., of a component. Further, in the drawings, the size and relative sizes of components may be exaggerated for clarity and/or descriptive purposes. While example embodiments may be practiced differently, the specific process sequence may be performed in a different order than that described. For example, two processes described consecutively may be performed substantially simultaneously or in reverse order to that described. In addition, like reference numerals denote like parts.

When an element is referred to as being "on" or "on," "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to" or "directly coupled to" another element, there are no intervening elements present.
