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 … …, "" upper "and" side (e.g., as 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 … …" may 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.

During frictional contact of the stirring member 630 with the floor surface to be cleaned, the cleaning liquid can be supplied to the stirring member 630, thereby achieving wet cleaning of the floor surface to be cleaned.

In one embodiment, the motor may be disposed on the housing 610 and drive the stirring member 630 to rotate by means of a synchronous belt transmission (i.e., operatively connected to the motor); in another embodiment, the motor may be provided in the stirring member 630 and can drive the stirring member 630 to rotate; in the present disclosure, the stirring member 630 is rotatable along a first axis; more preferably, the first axis may be a horizontal straight line of a lateral direction, i.e., a direction perpendicular to the front-rear direction; the front-rear direction is a moving direction of the surface cleaning apparatus when cleaning a surface to be cleaned.

The side cleaning assembly 660 is removably coupled to the housing 610 and is at least partially positioned below the housing 610; that is, at least part of the components of the side cleaning assembly 660 are located below the housing 610 and can contact the surface to be cleaned so that the side cleaning assembly 660 can also clean the surface to be cleaned.

In the present disclosure, the side cleaning assembly 660 of the present disclosure includes a self-cleaning module and a cleaning module; wherein the self-cleaning module is detachably connected to the cleaning module, whereby, when the self-cleaning module is connected to the cleaning module, it is detachably connected as a whole to the housing 610 of the cleaning head 600, i.e. in the present disclosure, the side cleaning assembly 660 is integrally mounted to the housing 610 of the cleaning head 600 and, correspondingly, is also integrally removable from the housing 610 of the cleaning head 600.

The cleaning module includes a housing 661, an edge cleaning brush 662, and a second connecting member 663. Wherein the housing 661 can be detachably provided to the housing 610.

The edge cleaning brush 662 is rotatably provided to the case 661, and at least a portion of the edge cleaning brush 662 protrudes from a side wall of the case 610, that is, one wall portion of the case 610 in a lateral direction.

In the present disclosure, the edge cleaning brush 662 may be driven by a motor to rotate along the second axis, wherein the motor may be disposed on the housing 610 and outside the casing 661, or may be disposed on the casing 661, for example, inside the casing 661, and the position of the motor is not limited in the present disclosure.

As shown in fig. 4, the edge cleaning brush 662 and the housing 661 are independently detachable from the cleaning head as a complete unit by a connection assembly; for example, the edge cleaning brush 662 and the housing 661 are independently removable from the cleaning head housing 610 as a complete unit by a connection assembly.

More specifically, as shown in FIG. 4, the side cleaning assembly 660 includes a columnar structure 668, and in a preferred embodiment, the columnar structure 668 can be provided to the housing 661, and more preferably, the columnar structure 668 can be integrally molded with the housing 661. More specifically, the housing 661 can be assembled from a plurality of components, and accordingly, the columnar structure 668 can be integrally molded with the uppermost component of the housing 661.

In the present disclosure, the outer circumferential surface of the columnar structure 668 is formed with a groove structure, at least part of which extends in the axial direction of the columnar structure 668, and at least part of which extends in the circumferential direction of the columnar structure 668.

More specifically, the groove structure includes a first groove 8A and a second groove 8B, wherein the first groove 8A is configured to extend in the axial direction of the columnar structure 668, and the second groove 8B is configured to extend in the circumferential direction of the columnar structure 668. The axial direction may be a vertical direction, and the circumferential direction may be a clockwise direction or a counterclockwise direction viewed from top to bottom.

In a preferred embodiment, the pillar-like structure 668 includes an upper end and a lower end, and the second groove 8B is configured to extend in the first direction as viewed from the upper end of the pillar-like structure 668 to the lower end of the pillar-like structure 668, i.e., as viewed in the top-to-bottom direction; as shown in fig. 4, the first direction may be a clockwise direction. Of course, the first direction may be a counterclockwise direction, and when the first direction is a counterclockwise direction, the groove structure may be formed to be symmetrical to the structure of fig. 4.

More specifically, the second groove 8B includes a start end connected through the first groove 8A and a stop end opposite to the start end, the start end and the stop end being disposed apart, so that the second groove 8B can have a predetermined length.

Taking fig. 4 as an example, when the cover structure 670 is mated with the pillar structure 668, the locking structure 1A of the cover structure 670 is first aligned with the first groove 8A, at this time, the first groove 8A is formed in an open shape at the upper end of the pillar structure 668, and the width of the first groove 8A gradually decreases in the top-to-bottom direction, i.e., the width of the opening of the first groove 8A is the largest, whereby guiding of the locking structure 1A can be achieved through the first groove 8A.

When the locking structure 1A of the cover structure 670 is aligned with the first recess 8A, moving the cover structure 670 in a direction approaching the pillar structure 668 and allowing the locking structure 1A of the cover structure 670 to enter the first recess 8A and approach the second recess 8B; accordingly, when the positions of the locking structure 1A and the second groove 8B are substantially parallel, the cover structure 670 is rotated clockwise, i.e., the locking structure 1A of the cover structure 670 can be entered into the inside of the second groove 8B, so that the cover structure 670 can be fitted with the columnar structure.

In a preferred embodiment, the terminating end is further from the upper end of the cylindrical structure 668 than the starting end, whereby a certain displacement of the cover structure 670 in the vertical direction (or axial direction) can be caused when the locking structure 1A of the cover structure 670 moves within the second recess 8B, which in turn enables a better fit of the cover structure 670 with the housing 610.

Fig. 5 and 6 are schematic structural views of a cover structure 670 according to one embodiment of the present disclosure.

As shown in fig. 5 and 6, the connection assembly includes a cover structure 670, the cover structure 670 including a front face, a back face opposite the front face, and an extension 671 extending downwardly from the back face; the front surface of the cover structure 670 is a surface of an upper end of the cover structure 670, and the reverse surface of the cover structure 670 is a surface of a lower end of the cover structure 670. Accordingly, the extension 671 is formed in a cylindrical structure, the axial direction of the extension 671 is set to a vertical direction (or up-down direction), and a lower end of the extension 671 has a preset distance from the opposite surface of the cover structure 670.

The extension 671 includes a locking structure 1A for cooperating with the slot structure to prevent the cover structure 670 from being separated from the pillar structure 668. In a specific embodiment, the locking structure 1A includes a boss extending inwardly from an inner surface of the extension 671.

In a specific embodiment, the number of the locking structures 1A is set to four, and the four locking structures 1A are uniformly distributed along the circumferential direction of the cover structure 670. Of course, in the present disclosure, the locking structures 1A may be provided in other numbers. Moreover, when the number of the locking structures 1A is plural, these locking structures 1A may also be unevenly distributed.

The number of groove structures may be set to be the same as the number of locking structures 1A, whereby the locking structures 1A can be fitted in one-to-one correspondence with the groove structures.

More preferably, as shown in fig. 6, one end of the locking structure 1A in the circumferential direction is formed in a chamfer shape, and the locking structure 1A can be guided by the chamfer structure when entering the second groove.

The cover structure 670 further includes a hook member 672, the hook member 672 being adapted to engage the housing 610 to prevent the cover structure 670 from being separated from the housing 610. More preferably, the hook member 672 is located outside the locking structure 1A in the reverse radial direction of the cover structure 670.

In a specific embodiment, the hook member 672 includes a connecting portion 2A and a hook body 2B, the upper end of the connecting portion 2A is connected to the opposite side of the cover structure 670, or the connecting portion 2A can extend downward from the opposite side of the cover structure 670, and accordingly, the lower end of the connecting portion 2A is connected to the hook body 2B, and the hook member 672 can be held by the interlock assembly 612.

In a preferred embodiment, the hook members 672 are also provided in four, and the hook members 672 are not coincident with the locking structure 1A on the opposite radial side of the cover structure 670, thereby enabling easy removal of the cover structure 670 from the columnar structure 688.

Fig. 8 is a schematic structural view of a housing according to one embodiment of the present disclosure. Fig. 9 is an enlarged schematic view of a portion a of fig. 8.

The cover structure 670 is also adapted to cooperate with the housing 610 when the locking structure 1A of the cover structure 670 cooperates with the groove structure, in other words, the cover structure 670 is also adapted to cooperate with the housing 610 at this time. In a preferred embodiment, movement of the cover structure 670 in an upward direction can be limited by engagement of the hook members 672 of the cover structure 670 with the interlock assembly 612.
