Description

Technical Field

[0001] The present disclosure relates to a cleaning assembly, a cleaning base, and a surface cleaning device. Background Art

[0002] The information provided in this section is only background information related to the present disclosure, and it is not necessarily prior art.

[0003] When an existing floor cleaner cleans a surface to be cleaned, it can supply a cleaning liquid to the surface to be cleaned, so that the surface to be cleaned is wetted. Then, through the frictional contact between the cleaning assembly of the cleaning base and the surface to be cleaned, the surface to be cleaned is wet-cleaned. At the same time, the used cleaning liquid is held in the recycling storage part as the contaminated cleaning liquid.

[0004] Basically, one end of the existing cleaning assembly is fixed and the other end is driven to rotate, or two short roller brushes are driven in the middle and combined into a long roller brush. Due to the need for both ends of the traditional cleaning assembly to be fixed, the cleaning assembly cannot reach the boundary of the cleaning base and be flush with the side of the cleaning base. When cleaning along the edge, the cleaning assembly cannot directly contact the garbage. Therefore, the existing floor cleaner has a good effect when cleaning the indoor floor. However, when the floor cleaner cleans a position such as a corner, it often cannot effectively clean it. Thus, after the user uses the floor cleaner to complete the cleaning of the indoor floor, they still need to manually clean components such as corners, which is time-consuming and laborious.

[0070] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present disclosure. Additionally, it should be noted that for the convenience of description, only the parts related to the present disclosure are shown in the drawings.

[0071] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and embodiments.

[0072] Unless otherwise specified, the exemplary embodiments / Examples shown will be understood to provide exemplary features of various details of some ways that can implement the technical concept of the present disclosure in practice. Therefore, unless otherwise specified, without departing from the technical concept of the present disclosure, the features of various embodiments / Examples can be additionally combined, separated, interchanged, and / or rearranged.

[0073] In the drawings, cross-hatching and / or shading are generally used to make the boundaries between adjacent components clear. Thus, unless stated, the presence or absence of cross-hatching or shading does not convey or imply any preference or requirement for the specific material, material properties, dimensions, proportions, commonality between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. Additionally, in the drawings, for clarity and / or descriptive purposes, the dimensions and relative dimensions of the components may be exaggerated. When the exemplary embodiments can be implemented differently, the specific process sequences can be performed in an order different from that described. For example, two consecutively described processes can be performed substantially simultaneously or in an order opposite to that described. Furthermore, the same reference numerals denote the same components.

[0074] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component can be directly on the other component, directly connected to or directly coupled to the other component, or there can be intervening components. However, when a component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there are no intervening components. To this end, the term "connected" can refer to physical connection, electrical connection, etc., and can have or not have intervening components.

[0075] For descriptive purposes, the present disclosure may use spatial relative terms such as "beneath", "below", "under", "lower", "above", "upper", "on", "over", "higher", and "side (e.g., as in "sidewall")" etc., so as to describe the relationship between one component and another (other) component as shown in the drawings. In addition to the orientation depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the drawings is flipped, the component described as "beneath" or "below" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "beneath" can encompass both "above" and "below" orientations. Additionally, the device can be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted.

[0076] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms. Additionally, when the terms "comprise" and / or "include" and their variants are used in this specification, it is stated that there are the stated features, integers, steps, operations, components, assemblies, and / or groups thereof, but does not preclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies, and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about", and other similar terms are used as approximate terms and not as terms of degree, and thus they are used to explain the inherent deviations of the measured, calculated, and / or provided values that would be recognized by a person of ordinary skill in the art.

[0077] Figure 1 is a schematic structural view of a surface cleaning device according to an embodiment of the present disclosure.

[0078] The surface cleaning device of the present disclosure is used to clean the floor surface to be cleaned. In a specific embodiment, the surface cleaning device can be a household handheld vacuum cleaner, a self - moving vacuum cleaner, a floor sweeping robot, a wet surface cleaning device, etc. That is to say, the cleaning base of the present disclosure can be used by a household handheld vacuum cleaner, a self - moving vacuum cleaner, a floor sweeping robot, and a wet surface cleaning device.

[0079] Figure 1 The shown surface cleaning device is a wet surface cleaning device. This wet surface cleaning device can perform wet cleaning on the surface to be cleaned and recycle the liquid after cleaning the floor surface to be cleaned back to the surface cleaning device.

[0080] Structurally, the surface cleaning device may include components such as a handle part 100, a frame part 200, a cleaning liquid storage part 300, a recycling storage part 400, a connecting part 500, and a cleaning base 600.

[0081] When the surface cleaning device of the present disclosure is in use, the cleaning base 600 is configured to be able to move on the floor surface to be cleaned, so as to perform wet cleaning on the floor surface to be cleaned through the cleaning base 600.

[0082] The handle part 100 can be arranged at the upper end of the frame part 200, and the handle part 100 and the frame part 200 can be detachably connected, so that the surface cleaning device can be operated by operating the handle part 100. In other words, the operator can control the attitude of the surface cleaning device by operating the handle part 100. For example, the frame part 200 of the surface cleaning device can rotate between an angle of a parallel attitude (parallel to the surface to be cleaned) and an angle of a self - supporting attitude, where the angle of the parallel attitude is 0° - 5°.

[0083] Thus, when the frame part 200 of the surface cleaning device is in an inclined attitude (i.e., at an angle of approximately 60° with the surface to be cleaned) or a parallel attitude (i.e., approximately parallel to the surface to be cleaned), the surface cleaning device can be in a cleaning mode; when the frame part 200 of the surface cleaning device is in a self - supporting attitude (the frame part 200 is arranged approximately vertically), at this time the surface cleaning device can be in a state of stopping work.

[0084] Physical buttons can be arranged on the handle part 100, so as to control the surface cleaning device through these physical buttons, such as controlling the start and stop of the surface cleaning device and controlling the liquid supply speed and suction power of the surface cleaning device, etc., thereby making the user experience of the surface cleaning device better.

[0085] In the present disclosure, the frame portion 200 is formed as the main load-bearing structure of the surface cleaning device, and the recycling and storage portion 400 of the surface cleaning device can be directly or indirectly fixed to the frame portion 200.

[0086] As Figure 1 shown, the frame portion 200 is formed with an accommodation space, and the recycling and storage portion 400 is detachably disposed in the frame portion 200 and located within the accommodation space. When there is a large amount of liquid stored in the recycling and storage portion 400, the user can remove the recycling and storage portion 400, pour out the internal sewage, and clean up the solid waste. At this time, a part of the outer surface of the recycling and storage portion 400 forms a part of the outer surface of the surface cleaner.

[0087] In order to recycle the liquid after cleaning the surface to be cleaned, the recycling and storage portion 400 can be connected to the cleaning base portion 600 through a recycling pipeline. Correspondingly, the mixture of sewage and gas (dirty water) can be recycled to the recycling and storage portion 400 through this recycling pipeline.

[0088] In the present disclosure, the surface cleaner further includes an electric suction source (not shown in the figure). The electric suction source can include a vacuum motor, thereby being able to generate a vacuum (negative pressure) through this electric suction source. At the same time, the electric suction source can be connected to the recycling and storage portion 400, so as to provide this negative pressure to the recycling and storage portion 400, thereby realizing the forced flow of gas and sewage in the recycling pipeline. In the present disclosure, the gas discharged from the electric suction source can flow to the outside of the surface cleaner through the gaps on a part of the outer surface of the surface cleaner.

[0089] In a preferred embodiment, the recycling and storage portion 400 can be located at the rear of the frame portion 200.

[0090] The frame portion 200 is connected to the cleaning base portion 600 through a connecting portion 500, so that the frame portion 200 is pivotally connected to the cleaning base portion 600. In the present disclosure, the frame portion 200 has at least two rotational degrees of freedom relative to the cleaning base portion 600, so as to enable the user to operate the surface cleaner more conveniently.

[0091] When the surface cleaner of the present disclosure is in use, the cleaning base portion 600 is configured to be able to move on the surface to be cleaned, so as to perform wet cleaning on the surface to be cleaned through the cleaning base portion 600.

[0092] Figure 2 is a schematic structural diagram of a cleaning assembly 620 according to an embodiment of the present disclosure. Figure 3 is a schematic structural diagram of the cleaning assembly 620 from another angle according to an embodiment of the present disclosure.

[0093] As shown in FIGS. 2 and Figure 3As shown, the cleaning base of the present disclosure may include components such as a housing assembly 610 and a cleaning assembly 620.

[0094] The housing assembly 610 is configured to be connected to the frame portion 200 through the connecting portion 500, and the housing assembly 610 is capable of moving on the surface to be cleaned. The surface of the housing assembly 610 close to the surface to be cleaned is formed as the bottom surface of the housing assembly 610. When the surface cleaner is cleaning the surface to be cleaned, the user can operate the surface cleaner so that the surface cleaner can move in the front-back direction, where the forward direction is the direction in which the cleaning base 600 is away from the user, and correspondingly, the backward direction is the direction in which the cleaning base 600 is close to the user. This front-back direction may also be referred to as the longitudinal direction. At the same time, the left-right direction can be defined by the forward direction and the backward direction. This left-right direction may also be referred to as the transverse direction.

[0095] The housing assembly 610 can define an accommodation space for the cleaning base, and the accommodation space is located in the front half of the cleaning base 600 so as to accommodate at least part of the cleaning assembly 620 in the accommodation space. Correspondingly, the cleaning assembly 620 is also located in the front half of the cleaning base 600.

[0096] A suction chamber is formed on the housing assembly 610. In the present disclosure, the suction chamber is disposed adjacent to the cleaning assembly 620 and is located behind the cleaning assembly 620. In the present disclosure, the suction chamber is connected to the recovery pipeline and is formed as the starting point of the recovery path. That is to say, the suction chamber of the present disclosure can communicate with the recovery storage portion 400 of the surface cleaner, so that the cleaning liquid after cleaning the surface to be cleaned can be recovered and stored in the recovery storage portion 400 via the suction chamber and the recovery pipeline.

[0097] The cleaning assembly 620 is configured to agitate the surface to be cleaned; that is to say, when the surface cleaner is performing a cleaning operation or a self-cleaning operation, the cleaning assembly 620 can be driven by a motor to rotate, whereby the cleaning assembly 620 can be in frictional contact with the surface to be cleaned, that is, the cleaning assembly 620 can cooperate with the cleaning liquid to scrub the surface to be cleaned to achieve the cleaning of the surface to be cleaned. During the process of the cleaning assembly 620 being in frictional contact with the surface to be cleaned, the cleaning liquid can be provided to the cleaning assembly 620 or the surface to be cleaned near the cleaning assembly 620, so as to achieve wet cleaning of the surface to be cleaned.

[0098] In the transverse direction, the housing assembly 610 includes two side portions. These two side portions also form two side portions of the cleaning base 600.

[0099] Figure 4 It is a schematic structural diagram of a support frame according to an embodiment of the present disclosure.

[0100] AsFigure 4 As shown, the cleaning base 600 of the present disclosure may further include a support frame 630. Specifically, the support frame 630 is detachably mounted on the housing assembly 610 and is located on one side of the housing assembly 610. At the same time, the front end of the support frame 630 extends to the side of the accommodation space of the housing assembly 610, and a driving device 631 can be mounted at the front end of the support frame 630.

[0101] Figure 5 It is a schematic structural diagram of a cleaning assembly according to an embodiment of the present disclosure.

[0102] As Figure 5 shown, the cleaning assembly 620 of the present disclosure may include a rotatably drivable roller brush 621. Specifically, the roller brush 621 can be driven by the driving device 631 mounted on the support frame 630 to rotate.

[0103] In addition, the cleaning assembly 620 further includes a mounting arm 622. The mounting arm 622 is detachably provided on the housing assembly 610 and is located on the other side of the housing assembly 610. That is to say, one of the two sides of the housing assembly 610 is provided with the support frame 630, and the other is provided with the mounting arm 622.

[0104] The rear end of the mounting arm 622 can be fixed to the housing assembly 610, and the front end of the mounting arm 622 can extend to the side of the accommodation space. Accordingly, the mounting arm 622 can form at least part of the outer surface of the cleaning base 600. Moreover, the front end of the mounting arm 622 can rotatably support the roller brush 621. Thus, the roller brush 621 and the mounting arm 622 can form a component and can be detached from the housing assembly 610 together.

[0105] When the cleaning assembly 620 is mounted on the housing assembly 610, the other end of the roller brush 621 can be rotatably provided on the support frame 630. Accordingly, the driving device 631 provided on the support frame 630 can be located inside the roller brush 621. At this time, the roller brush 621 can be located in the accommodation space of the housing assembly 610 and can rotate relative to the housing assembly 610 based on the power provided by the driving device 631.

[0106] Figure 6 It is a schematic structural diagram of a roller brush according to an embodiment of the present disclosure.

[0107] Referring again to Figure 5 and Figure 6, the drum brush 621 of the present disclosure may include a core body 621A, a cleaning member 621B, and a brush row 621C. Among them, the core body 621A defines a horizontal rotation axis; that is to say, when the drum brush 621 of the present disclosure rotates, its rotation axis is a horizontal straight line in the horizontal direction, and the rotation axis of the drum brush 621 is the rotation axis of the core body 621A.

[0108] The cleaning member 621B can be prepared from materials such as flannelette, and it can be disposed on the outer peripheral surface of the core body 621A. When the core body 621A is driven to rotate by the driving device 631, the cleaning member 621B can be driven to rotate by the core body 621A. Correspondingly, the cleaning member 621B can be in frictional contact with the surface to be cleaned, so as to clean the surface to be cleaned through the cleaning member 621B.

[0109] In a preferred embodiment, the cleaning member 621B can be fixed to the outer peripheral surface of the core body 621A by glue or Velcro, etc.; the brush row 621C is arranged near at least one end of the core body 621A and is arranged along the circumferential direction of the end; among them, the brush row 621C includes a first brush 621C1 and a second brush 621C2. The first brush 621C1 is arranged at a first angle relative to the core body 621A, and the second brush 621C2 is arranged at a second angle relative to the core body 621A, and the first angle and the second angle are different.

[0110] That is to say, by setting different first angles and second angles, the first brush 621C1 and the second brush 621C2 can clean different areas, and it can be ensured that the surface to be cleaned in the entire horizontal direction of the cleaning base 600 can be cleaned.

[0111] In a preferred embodiment, the first angle is less than the second angle; for example, the first angle can be at least 45°, and the second angle is 90°; that is to say, the second brush 621C2 can be arranged along the radial direction of the core body 621A. Correspondingly, the angle between the first brush 621C1 and the rotation axis of the core body 621A can be greater than or equal to 45° and less than 90°.

[0112] Referring again to Figure 6 , in the present disclosure, the core body 621A may include a cylindrical portion 621A1 and an end member 621A2. Among them, a ring-shaped protrusion is provided on the end member 621A2; and one end of the end member 621A2 can be inserted into the inside of the cylindrical portion 621A1, and the ring-shaped protrusion 621A3 can be in abutting contact with the end of the cylindrical portion 621A1. Thus, the ring-shaped protrusion 621A3 can limit the insertion depth of the end member 621A2.

[0113] In addition, the end of the cleaning member 621B is blocked by the annular protrusion. In particular, when the cleaning member 621B is formed as a crawler-type cleaning member, the cleaning member 621B will not deviate on the core body 621A, that is, the cleaning member 621B will not interfere with the brush row 621C.

[0114] The other end of the end member 621A2 is formed with a circumferential base, on which the cleaning member 621B is not provided, and the brush row 621C is provided on the circumferential base.

[0115] In one embodiment, the brush rows 621C can be provided in multiple groups, and the multiple groups of brush rows 621C can be arranged along the axial direction of the core body 621A. These brush rows 621C are arranged in such a way that there is no area where cleaning is missed in the lateral direction of the cleaning assembly 620.

[0116] As Figure 5 and Figure 6 shown, the brush row 621C of the present disclosure can be provided as a group; this group of brush rows 621C includes a plurality of first bristles 621C1 and a plurality of second bristles 621C2; the first bristles 621C1 have a connecting end and a free end, and at least a part of the free end of at least one first bristle 621C1 protrudes from the side of the housing assembly 610. Thus, the free end of the first bristle 621C1 can contact the surface to be cleaned outside in the lateral direction of the cleaning base 600, so as to effectively clean components such as the corner. In other words, the length of the first bristle 621C1 (the bristles facing the outside) of the present disclosure needs to extend outside the mounting arm 622 (and / or the support frame 630) to achieve the effect of zero-contact edge cleaning.

[0117] The second bristles 621C2 have a connecting end and a free end, and the free end of at least one second bristle 621C2 interferes with the cleaning member 621B. Thus, the gap between the brush row 621C and the cleaning member 621B can be eliminated, preventing the generation of cleaning blind spots.

[0118] In the present disclosure, the brush row 621C can further include a third bristle (not shown in the figure), and the third bristle is arranged at a third angle with respect to the core body, and the third angle can be slightly larger than the second angle. Thus, the third bristle can have a greater degree of interference with the cleaning member 621B to improve the cleaning effect on the surface to be cleaned.

[0119] More preferably, the first bristles 621C1 include bristles that are softer than the second bristles 621C2. In other words, both the first bristles 621C1 and the second bristles 621C2 of the present disclosure can be made of bristles, but the first bristles 621C1 and the second bristles 621C2 are made of different bristles; in a specific embodiment, the diameter of the first bristles 621C1 can be greater than the diameter of the second bristles 621C2. Thus, the first bristles 621C1 have greater hardness and elasticity, so that after the first bristles 621C1 interfere with the bristle interference portion, they can return to the original shape more quickly and clean the surface to be cleaned.

[0120] The first bristles 621C1 have a first length; and the second bristles 621C2 have a second length, and the second length is less than the first length, so that the free ends of the first bristles 621C1 and the second bristles 621C2 can be located on substantially the same cylindrical surface. Accordingly, the first bristles 621C1 and the second bristles 621C2 have substantially the same interference amount with the surface to be cleaned.

[0121] The first bristles 621C1 and the second bristles 621C2 are arranged alternately along the circumferential direction of the end. Thus, the first bristles 621C1 and the second bristles 621C2 can alternately contact the surface to be cleaned to improve the cleaning effect on the surface to be cleaned.

[0122] In the present disclosure, at least a part of the contact areas of the first bristles 621C1 and the second bristles 621C2 with the surface to be cleaned overlap, so that there will be no cleaning blind spots at the positions corresponding to the bristle row 621C.

[0123] In the present disclosure, the mounting arm 622 is formed as a part of the cover structure; the cover structure is used to close one end of the cleaning assembly 620, and the bristle interference portion is formed as a part of the cover structure. Specifically, the front end of the mounting arm 622 is formed as the bristle interference portion. At this time, the bristle interference portion is located on the side of the housing assembly 610 and is used to interfere with the first bristles 621C1 when the cleaning assembly 620 rotates. During the interference between the bristle interference portion and the first bristles 621C1, the extension angle of the first bristles 621C1 is temporarily changed by the bristle interference portion; at the same time, when the first bristles 621C1 extend beyond the bristle interference portion, the first bristles 621C1 can return to a substantially straight state under the action of the elastic restoring force and interfere with the surface to be cleaned to clean the surface to be cleaned.

[0124] In the present disclosure, when the cleaning member 621B is provided with cleaning liquid, the cleaning member 621B can perform wet cleaning on the surface to be cleaned, but the bristle row 621C is not provided with cleaning liquid. It only performs a cleaning operation on the surface to be cleaned, and the dust and other garbage disturbed by the interference of the bristle row 621C with the surface to be cleaned will also be sucked into the recycling storage portion 400.

[0125] In some embodiments, the end of the core body includes a first type of groove and a second type of groove; the first type of groove is for mounting the first bristles 621C1; the second type of groove is for mounting the second bristles 621C2; wherein, the extending directions of the first type of groove and the second type of groove relative to the rotation axis at the end are different.

[0126] In the present disclosure, a receiving groove may be provided on the housing assembly 610, and a cleaning liquid storage portion 300 may be provided in the receiving groove.

[0127] The cleaning liquid storage portion 300 is formed in the shape of a box to store the cleaning liquid therein. In one embodiment, the cleaning liquid may be clean water. Of course, those skilled in the art should know that a mixture of clean water and a cleaning agent, etc. may also be stored in the cleaning liquid storage portion 300.

[0128] In the present disclosure, the cleaning liquid storage portion 300 can be detached from the housing assembly 610 and the cleaning liquid can be manually filled by the user; of course, the cleaning liquid of the cleaning liquid storage portion 300 of the present disclosure can also be filled through a cleaning liquid interface provided on the housing assembly 610.

[0129] In another embodiment, the cleaning liquid storage portion 300 may also be provided on the frame portion 200. At this time, a receiving space is formed on the frame portion 200, and the cleaning liquid storage portion 300 can be disposed in the receiving space, and a part of the outer surface of the cleaning liquid storage portion 300 forms a part of the outer surface of the surface cleaning device.

[0130] The cleaning base 600 of the present disclosure may include a liquid distribution system for supplying the cleaning liquid stored in the cleaning liquid storage portion 300 to the cleaning assembly 620. Specifically, in the present disclosure, the liquid distribution system may include a water pump and a distribution member 142. The water pump is used to extract the cleaning liquid in the cleaning liquid storage portion 300 and supply the pressurized cleaning liquid to the distribution member 142. The distribution member 142 is disposed on the housing assembly 610 and is located behind the cleaning assembly 620. The lower end of the distribution member 142 is located above the cleaning member 640, and at least a part of the liquid provided by the distribution member 142 can be discharged to the cleaning member 640 and supplied to the cleaning member 621B via the cleaning member 640.

[0131] Figure 7 It is a schematic structural diagram of another angle of a partial structure of a cleaning base according to an embodiment of the present disclosure. Figure 8 is Figure 7 An enlarged schematic view of part A of Figure 9Schematic structural diagram of a dispensing component according to an embodiment of the present disclosure. Figure 10 is Figure 9 An enlarged schematic diagram of part B of Figure 11 Schematic structural diagram of the dispensing component from another angle according to an embodiment of the present disclosure.

[0132] Specifically, the dispensing component 142 includes a base portion 142A which has a front surface and a rear surface. Among them, a liquid dispensing channel 142C is formed on the rear surface of the base portion 142A. The liquid pressurized by a water pump can be provided to the liquid dispensing channel 142C and be dispensed by the liquid dispensing channel 142C. In a preferred embodiment, the liquid dispensing channel 142C has a plurality of ends, and drain holes 142D are formed at the ends of the liquid dispensing channel 142C. Correspondingly, the drain holes 142D are provided in plurality, and the drain holes 142D penetrate through the base portion 142A. Thus, the cleaning liquid can flow to the front surface of the base portion 142A via the drain holes 142D.

[0133] The front surface of the base portion 142A is provided with a rib structure 142B; in the present disclosure, the rib structures 142B can be distributed at substantially equal intervals along the length direction of the base portion 142A (i.e., along the transverse direction of the cleaning base 100). Thus, a liquid dispensing space is formed between two adjacent rib structures 142B.

[0134] In a specific embodiment, some of the rib structures 142B in the rib structure 142B are correspondingly arranged with the drain holes 142D, and at least part of the rib structures 142B correspondingly arranged with the drain holes 142D are spaced from the front surface of the base portion 142A. Thus, the drain holes 142D can communicate with the liquid dispensing spaces on both sides of the rib structure 142B, so that the cleaning liquid can be discharged to the liquid dispensing space via the drain holes 142D.

[0135] In a specific embodiment, the connection between the drain holes 142D and the liquid dispensing space is located at a corner of the liquid dispensing space, where Figure 9 taking the direction shown in

[0136] as an example, part of these connection points are located in the upper left corner of the liquid dispensing space, and part are located in the upper right corner of the liquid dispensing space. A diversion structure 142E is provided on the rib structure 142B, and the diversion structure 142E is arranged such that the liquid discharged from the drain holes 142D is diverted by the diversion structure 142E to the middle region in the transverse direction of the liquid dispensing space.

[0137] Moreover, the liquid distribution space includes a rear side wall 142F which is formed as a part of the front surface of the base portion 142A. The rear side wall 142F is inclined forward in the lateral direction away from the diversion structure 142E, so as to be able to discharge the liquid entering the liquid distribution space to the front part of the liquid distribution space as soon as possible and flow out of the liquid distribution space from the front end of the liquid distribution space.

[0138] In addition, the liquid distribution space further includes a bottom wall 142G which is arranged as a V-shaped surface. And the bottom wall 142G gradually descends and then gradually ascends in the lateral direction. Thus, the bottom wall 142G includes a low region which is approximately located at the approximate middle position of the liquid distribution space in the lateral direction, so as to form a liquid flow path through this low region.

[0139] Moreover, the bottom wall 142G is inclined downward in the direction from the rear to the front. Thus, the cleaning liquid can flow forward on the bottom wall 142G under the action of gravity and flow to the cleaning component 640. At this time, at least a part of the cleaning component 640 (for example, the part located below the distribution component 142) is arranged to be inclined downward in the direction from the rear to the front. Thus, the cleaning liquid can be provided to the cleaning component 621B via the cleaning component 640 under the action of gravity.

[0140] In the present disclosure, through the redesigned liquid distribution system, the cleaning liquid can be more evenly distributed on the cleaning member, effectively avoiding the phenomenon of uneven dry and wet on the cleaning component 621B, and improving the cleaning effect of the surface cleaning device of the present disclosure.
