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., as in "sidewall"), etc., 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. 1 and 2 are schematic structural views of a cleaning base 10 of a surface cleaning apparatus according to one embodiment of the present disclosure.

The cleaning base 10 as shown in fig. 1 and 2, which can be applied to a surface cleaning apparatus, can clean a surface to be cleaned by the cleaning base when a user operates the surface cleaning apparatus.

In one implementation, the connection part 100 may be formed as a snap-fit structure, thereby facilitating the user's mounting and dismounting of the cleaning base part 10 to and from the frame part of the surface cleaning apparatus; at this time, the frame portion can also mount different cleaning bases 10 and achieve different ways of cleaning.

In a preferred embodiment, the connection part 100 is further provided with an electrical connection terminal 110, whereby the electrical connection terminal 110 can be connected with a battery of the frame part to supply power to the driving means 160 of the cleaning base part 10 when the connection part 100 is connected to the frame part of the surface cleaning apparatus.

The cleaning base 10 may further comprise a housing portion 200, the housing portion 200 and the connection portion 100 being connected by a connection member 120, in a preferred embodiment the connection member 120 may be a universal joint, thereby enabling tilting of the frame portion in multiple directions relative to the housing portion 200.

In one embodiment, the housing portion 200 is rotatably provided with a roller wheel, so that the movement of the cleaning base portion 10 is achieved by rotation of the roller wheel 130 over the surface to be cleaned when the cleaning base portion 10 is performing a cleaning operation.

Referring again to fig. 2, the cleaning base 10 may further include a first cover 300, and the first cover 300 is disposed on the housing portion 200. In one embodiment, the first cover 300 is non-detachably disposed on the housing 200, and an inner space is formed between the first cover and the housing 200, and some components of the cleaning base 10, such as the driving device 160, may be disposed in the inner space.

In another embodiment, the first cover 300 may also be detachably disposed on the housing 200.

Fig. 3 is a partial schematic structural view of a cleaning base of a surface cleaning apparatus according to one embodiment of the present disclosure.

As shown in fig. 3, the housing part 200 includes a receiving space 210 and a suction inlet 220 communicating with the receiving space 210; in the present disclosure, the accommodating space 210 may also be referred to as a roll brush chamber, a brush roll chamber, or the like.

Wherein the accommodating space 210 may accommodate therein the first roll brush part 500 and the like, the suction inlet 220 may be in communication with the suction duct 140, thereby enabling a mixture of dust and gas, or a mixture of dust, used cleaning liquid and gas, to enter the suction duct 140 through the suction inlet 220 and be sucked to the frame part of the surface cleaning apparatus via the suction duct 140.

In a preferred embodiment, the first cover 300 and the housing part 200 together form the accommodating space 210; in a more preferred embodiment, the first cover 300 forms the suction inlet 220 described below together with the housing part 200.

In one embodiment, as shown in fig. 3, the first rolling brush part 500 is arranged in a hanging manner, such that the first rolling brush part 500 has a fixed end and a free end, wherein the fixed end is an end connected with the driving rod 410, and the free end is a hanging end.

As one implementation, the outer contour of the first rolling brush part 500 is tapered or substantially tapered, and at least a portion of the first rolling brush part 500 is in contact with the surface to be cleaned. For example, at least part of bristles of the bristle row 510 of the first roll brush part 500 are in contact with the surface to be cleaned to disturb dust on the surface to be cleaned, thereby achieving cleaning of the surface to be cleaned.

With continued reference to fig. 3, the first roller brush 500 of the present disclosure is disposed laterally, e.g., laterally, in the receiving space. Wherein when the surface cleaning apparatus is in use, the user moves the cleaning base forward or backward, whereby the front-to-back direction of the cleaning base, i.e. the longitudinal direction of the cleaning base, the lateral direction, i.e. the direction substantially perpendicular to the longitudinal direction. It should be understood by those skilled in the art that the first roll brush 500 is disposed laterally does not mean that the rotation axis OX of the first roll brush 500 is perpendicular to the longitudinal direction, but that the rotation axis OX may be at a predetermined angle with respect to the longitudinal direction, the predetermined angle being within a certain range. Moreover, the transverse direction does not refer to the horizontal direction, and may be an angle with the horizontal direction.

As shown in fig. 3, in the present disclosure, the first rolling brush parts 500 are provided in two, and free ends of the two first rolling brush parts 500 are disposed close to each other and have a preset distance; thereby forming a gap between the two free ends of the first roll brush part 500.

More preferably, the gap of the two first roller brush parts 500 corresponds to the position of the suction inlet, for example, the gap is disposed adjacent to the suction inlet, whereby the disturbed dust can be conveyed to the vicinity of the suction inlet along with the protrusions 520 which are spirally disposed, so that the disturbed dust can be easily sucked into the suction inlet, greatly improving the cleaning effect.

In the present disclosure, as shown in fig. 1, the first roller brush 500 is disposed biased toward the suction inlet from the fixed end to the free end, whereby dust on the surface to be cleaned, which is agitated by the first roller brush 500, can be more easily sucked into the suction inlet.

That is, with the first roller brush 500 thus provided, the first roller brush 500 can make the flow path between the second roller brush 600 and the first roller brush 500 smoother, and the cleaning effect of the surface to be cleaned is also better.

More preferably, the outer surface of the main body 501 of the first roll brush 500 is provided with a helically extending protrusion 520 from the fixed end to the free end, and the bristle row 510 extends outwardly from the protrusion 520.

In the present disclosure, the protrusion 520 extends outwardly from the outer surface of the main body 501 of the first rolling brush 500 by a second radial distance that decreases from the fixed end to the free end of the first rolling brush 500.

In a specific implementation, the protrusion 520 includes a base 521 and a pair of ridges 522, the base 521 and the pair of ridges 522 being disposed in sequence radially outward from the outer surface of the body portion 501 of the first roller brush portion 500, the bristle row 510 extending outward from the base 521 and being disposed between the pair of ridges 522, the tips of the bristle row 510 protruding from the pair of base 521.

The support portion 150 is used to fix the driving device 160, and in one embodiment, the driving device 160 may be a direct current motor or a stepping motor, which is commonly used, and may be held by the support portion 150. Of course, the driving device 160 may be fixed to the housing 200 and held by the housing 200. More preferably, the driving device 160 can be held together by the supporting portion 150 and the housing portion 200.

In a preferred embodiment, the support portion 150 can be formed separately from the housing portion 200, although those skilled in the art will appreciate that the support portion 150 can also be formed integrally with the housing portion 200.

As shown in fig. 3, the driving synchronous pulley 170 is mounted on the output shaft of the driving device 160, and the driven synchronous pulley 180 is mounted on the driving rod 410, and the driving synchronous pulley 170 and the driven synchronous pulley 180 are in transmission connection through a synchronous belt, so that the driving rod 410 can be driven to rotate by the driving device 160. Of course, the timing belt transmission mechanism may be replaced by a chain transmission mechanism, a gear transmission mechanism, or the like, and will not be described in detail here.

Fig. 4 is a schematic cross-sectional structural view of a cleaning base according to one embodiment of the present disclosure.

In a preferred embodiment, the number of bearings 400 is two, for example two ball bearings. Of course, the two bearings 400 may also be provided as angular contact bearings mounted back-to-back or face-to-face.

The outer ring of one of the two bearings 400 is positioned by the stepped portion 151, and the outer ring of the other of the two bearings 400 is positioned by the hooking portion 152, thereby achieving the fixation of the axial positions of the two bearings 400.

As shown in fig. 4, the cleaning base 10 of the present disclosure further includes a driving lever 410, where the driving lever 410 is disposed on the bearing 400 and rotatably supported by the bearing 400, that is, the driving lever 410 may be fixed to an inner ring of the bearing 400, for example, the driving lever 410 may be sized to be slightly larger than an inner diameter of the inner ring of the bearing 400, so that the driving lever 410 cannot axially move with respect to the bearing 400 by interference fit.

Also, due to the characteristics of the bearing 400, the driving lever 410 can be rotated, and at this time, the driving device 160 can drive the driving lever 410 to rotate.

In the present disclosure, one end of the driving lever 410 is positioned in the receiving space 210, and the first rolling brush part 500 is installed at the end; the other end of the driving lever 410 is located outside the accommodating space 210, and a driven timing pulley 180 is mounted at the end.

More preferably, the cleaning base may further include a second rolling brush part 600 rotatably provided to the housing part 200 and located in front of the first rolling brush part 500, and a portion of a vacuum suction flow path is formed between the first and second rolling brush parts 500 and 600, whereby the surface to be cleaned can be cleaned more cleanly by the provision of the first and second rolling brush parts 500 and 600. Specifically, when the surface cleaning device cleans the surface to be cleaned, the surface to be cleaned is cleaned by the second rolling brush part 600 while the cleaning base part moves forward, and dust on the surface to be cleaned is agitated; the surface to be cleaned is then cleaned again by the first roller brush 500, agitating dust on the surface to be cleaned, thereby making the surface to be cleaned cleaner after cleaning.

In the present disclosure, the second rolling brush part 600 may be driven to rotate, for example, the second rolling brush part 600 may be formed as a cylindrical rolling brush, and a driving device, such as a motor, may be disposed inside the second rolling brush part 600, so that the second rolling brush part 600 may rotate, and accordingly, at this time, both ends of the second rolling brush part 600 may be rotatably supported to the housing part 200 through bearings.
