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 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. For purposes of this disclosure, the term "connected" may refer to physically, electrically, etc., and may or may not have intermediate components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "below … …," below … …, "" below … …, "" below, "" above … …, "" above, "" … …, "" upper, "and" side (e.g., as in "sidewall") to describe the relationship of one component to another (other) component as shown 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. Furthermore, when the terms "comprises" and/or "comprising" and variations thereof are used in this specification, the presence of stated features, integers, steps, operations, elements, components and/or groups thereof are stated but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and/or groups thereof. It is also noted that, as used herein, the terms "substantially," "about," and other similar terms are used as approximate terms and not as degree terms, and as such, are used to interpret inherent deviations in measured values, calculated values, and/or provided values that would be recognized by one of ordinary skill in the art.

As an implementation form, the supporting component 120 includes:

a support shaft 121; and

at least two support bearings 122;

at least two supporting bearings 122 are sleeved on the supporting shaft 121 and disposed between the supporting shaft 121 and the cleaning assembly 110, so that the cleaning assembly 110 can rotate relative to the supporting shaft 121 through the supporting bearings.

In the present disclosure, one end of the supporting shaft 121 may protrude from the cleaning assembly 110, so that the supporting shaft 121 is fixed to the housing of the cleaning head device, thereby fixing the position between the supporting assembly 120 and the housing.

The other end of the supporting shaft 121 is located inside the cleaning assembly 110, for example, the other end of the supporting shaft 121 is located in the middle of the cleaning assembly 110, and at this time, a certain installation space is reserved for the driving device 130 and the connecting assembly 140 installed on the supporting shaft 121.

At this time, the connection assembly 140 may be located in the supporting body 111 and be in transmission connection with the supporting body 111, for example, the second connector 142 of the connection assembly 140 is in interference fit or adhesive connection with the inner wall surface of the supporting body 111.

Preferably, the supporting body 111 is provided to be rigid, and the cleaning part 112 is deformable when an external force is applied to the cleaning part 112.

In the present disclosure, when the cleaning portion 112 is brought into contact with the surface to be cleaned, the components of the contact area can be deformed, and a flattened shape can be achieved. The flattening of the cleaning portion 112 increases the effective cleaning area and cleaning force of the cleaning device when cleaning the cleaning surface, thereby improving the cleaning effect. Further, generally, during cleaning by the cleaning device, some filaments will adhere to the surface of the cleaning device, and the filaments may be caused to fall off the cleaning portion 112 by deformation of the cleaning portion 112, and then the fallen filaments may be sucked away. Meanwhile, the inside of the cleaning part 112 is supported by a rigid driving shaft, thus preventing the entire cleaning apparatus from being deformed.
