Description

Surface cleaning apparatus

Technical Field

The present disclosure relates to cleaning devices, and more particularly, to a surface cleaning device.

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 apparatuses 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 several 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 detection of the water level in the supply tank or the recovery tank.

Detailed Description

The present disclosure will be described in further detail with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limitations of the present disclosure. It should be further noted that, for the convenience of description, only the portions relevant to the present disclosure are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict. Technical solutions of the present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Unless otherwise indicated, the illustrated exemplary embodiments/examples are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure may be practiced. 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 specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for a particular material, material property, dimension, 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 "over," "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. For purposes of this disclosure, the term "connected" may refer to physically connected, electrically connected, and the like, with or without intervening components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "below … …," below … …, "" below … …, "" below, "" above … …, "" above, "" … …, "" higher, "and" side (e.g., "in the sidewall") to describe one component's relationship to another (other) component as illustrated in the figures. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below … …" can encompass both an orientation of "above" and "below". Further, the devices may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
