Detailed Description

The present disclosure is described in further detail below with reference to the drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant content and not limiting of the present disclosure. It should be further noted that, for convenience of description, only a portion relevant to the present disclosure is shown in the drawings.

In addition, embodiments of the present disclosure and features of the embodiments may be combined with each other without conflict. The technical aspects of the present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Unless otherwise indicated, the exemplary implementations/embodiments shown 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. Thus, unless otherwise indicated, features of the various implementations/embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concepts of the present disclosure.

The use of cross-hatching and/or shading in the drawings is typically used to clarify the boundaries between adjacent components. As such, the presence or absence of cross-hatching or shading does not convey or represent any preference or requirement for a particular material, material property, dimension, proportion, commonality between illustrated components, and/or any other characteristic, attribute, property, etc. of a component, unless indicated. In addition, in the drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. While the exemplary embodiments may be variously implemented, the specific process sequences may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in reverse order from that described. Moreover, like reference numerals designate 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 this reason, the term "connected" may refer to physical connections, electrical connections, and the like, with or without intermediate components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "under … …," under … …, "" under … …, "" lower, "" above … …, "" upper, "" above … …, "" higher "and" side (e.g., in "sidewall") to describe one component's relationship to another (other) component as illustrated in the figures. In addition to the orientations depicted in the drawings, the spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below" … … can encompass both an orientation of "above" and "below". Furthermore, the device 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 only 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. Furthermore, when the terms "comprises" and/or "comprising," and variations thereof, are used in the present specification, the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof is described, but the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof is not precluded. It is also noted that, as used herein, the terms "substantially," "about," and other similar terms are used as approximation terms and not as degree terms, and as such, are used to explain the inherent deviations of measured, calculated, and/or provided values that would be recognized by one of ordinary skill in the art.

Fig. 4 is a schematic overall structural view of another perspective of a cleaning base of a surface cleaning apparatus of one embodiment of the present disclosure, with a self-adjusting detection subsystem 140 shown in fig. 4.

The surface cleaning apparatus 1000 of the present disclosure will first be described with reference to fig. 1 to 5.

Referring to fig. 1 to 5, a surface cleaning apparatus 1000 of the present disclosure for wet cleaning a surface to be cleaned, the surface cleaning apparatus 1000 capable of distributing a cleaning liquid to the surface to be cleaned and recovering the used cleaning liquid and dirt on the surface to be cleaned, the surface cleaning apparatus 1000 comprising:

a cleaning liquid storage part 220, the cleaning liquid storage part 220 storing cleaning liquid;

a cleaning base 100, the cleaning base 100 including a stirring member 110 (which may be a roller brush, for example) configured to be in frictional contact with a surface to be cleaned;

wherein the cleaning base 100 communicates with the cleaning liquid storage part 220 to receive the cleaning liquid supplied from the cleaning liquid storage part 220, the cleaning base 100 is movable on the surface to be cleaned, the cleaning liquid supplied from the cleaning liquid storage part 220 is dispensed to the surface to be cleaned by the stirring member 110, and the used cleaning liquid and dirt on the surface to be cleaned are sucked through the suction part 120 of the cleaning base 100 to be recovered;

a recovery storage part 230, the recovery storage part 230 being in communication with the cleaning base part 100 to receive and store the used cleaning liquid recovered by the cleaning base part 100 and dirt on the surface to be cleaned;

a main body 200, the main body 200 accommodating at least the cleaning liquid storage section 220 and the recovery storage section 230;

at least one roller 130, the roller 130 being disposed on the cleaning base 100, the roller 130 facilitating reciprocal movement of the cleaning base 100 relative to the surface to be cleaned;

a self-adjusting detection subsystem 140, the detection subsystem 140 comprising a support assembly 141 pivotally mounted in combination with at least a portion of the bottom of the cleaning base 100, and a roll detector 142 mounted in combination with the support assembly 141 for detecting a movement of the cleaning base 100 relative to a surface to be cleaned, the support assembly 141 automatically operating to vary the height of the roll detector 142 relative to the cleaning base 100 in response to a change in torque of the roll detector 142.

In some use scenarios of the surface cleaning apparatus 1000, the cleaning base 100 is operated by a user to reciprocate, the torque to which the rolling detector 142 is subjected will vary (the direction of static friction force to which it is subjected), and if the rolling detector 142 has a fixed height relative to the cleaning base 100 (e.g., the rolling detector 142 is exposed to a fixed dimension from the bottom of the cleaning base), the rolling detector 142 may slip, thereby causing a detection error in the direction of movement of the cleaning base 100, etc.

The surface cleaning apparatus 1000 of the present disclosure can accurately detect a moving direction (front-rear direction) or the like of the cleaning base 100 by providing the rolling detector 142, and can automatically operate/act in response to a change in torque received by the rolling detector 142 when the torque received by the rolling detector 142 changes by providing the supporting member 141 pivotally mounted in conjunction with the bottom of the cleaning base 100, thereby causing a corresponding change in the height of the rolling detector 142 relative to the cleaning base 100, avoiding a problem of slipping of the rolling detector 142 or the like occurring when the torque received by the rolling detector 142 changes.
