[0074] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0075] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0076] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0077] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0078] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0079] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0080] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, 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 rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0081] Figure 1 This is a schematic diagram of a wet surface cleaning apparatus according to one embodiment of the present disclosure.

[0082] like Figure 1 As shown, the wet surface cleaning device disclosed herein is used to clean the floor surface to be cleaned. Preferably, the wet surface cleaning device is capable of performing wet cleaning on the floor surface to be cleaned and recovering the liquid after cleaning the floor surface to be cleaned back into the wet surface cleaning device.

[0083] like Figure 1 As shown, structurally, the wet surface cleaning device may include components such as a handle 100, a frame 200, a cleaning solution storage unit 300, a recovery storage unit 400, a connecting part 500, and a cleaning head 600.

[0084] In use, the wet surface cleaning apparatus of this disclosure has a cleaning head 600 configured to move on the floor surface to be cleaned, so as to perform wet cleaning on the floor surface to be cleaned by means of the cleaning head 600.

[0085] The handle 100 is used to operate the wet surface cleaning device. More specifically, on the one hand, the operator can control the posture of the wet surface cleaning device by operating the handle 100. For example, by controlling the handle 100, the wet surface cleaning device can be in a tilted state (i.e., at an angle of approximately 60° to the surface to be cleaned) or a roughly flat state (i.e., roughly parallel to the surface to be cleaned). Correspondingly, when the frame 200 of the wet surface cleaning device is in a tilted state (i.e., at an angle of approximately 60° to the surface to be cleaned) or a roughly flat state (i.e., roughly parallel to the surface to be cleaned), the wet surface cleaning device is in cleaning mode and can clean the surface to be cleaned. Correspondingly, when the handle 100 is operated to make the frame 200 of the wet surface cleaning device vertical, the wet surface cleaning device is in a stopped state, or when the wet surface cleaning device is in a base station position, the frame 200 of the wet surface cleaning device is also in a roughly vertical state.

[0086] On the other hand, physical buttons can be provided on the handle 100, so as to control the wet surface cleaning equipment through these physical buttons, such as controlling the start and stop of the wet surface cleaning equipment, as well as controlling the liquid supply speed and suction power of the wet surface cleaning equipment, thereby making the user experience of the wet surface cleaning equipment better.

[0087] The handle portion 100 can be disposed at the upper end of the frame portion 200, thereby enabling the operation of the wet surface cleaning device by operating the handle portion 100. In this disclosure, the frame portion 200 is formed as the main load-bearing structure of the wet surface cleaning device, and the cleaning liquid storage portion 300 and the recovery storage portion 400 of the wet surface cleaning device can both be directly or indirectly fixed to the frame portion 200.

[0088] The cleaning fluid storage section 300 is formed in the shape of a box to store cleaning fluid. In one embodiment, the cleaning fluid can be purified water. Of course, those skilled in the art will know that the cleaning fluid storage section 300 can also store a mixture of purified water and cleaning agent, etc.

[0089] The frame portion 200 has a receiving space, and the cleaning fluid storage portion 300 can be disposed in the receiving space, such that a portion of the outer surface of the cleaning fluid storage portion 300 is formed as part of the outer surface of the wet surface cleaning device.

[0090] In this disclosure, the cleaning fluid storage unit 300 can be detached from the frame unit 200 and filled with cleaning fluid manually by the user; of course, the cleaning fluid storage unit 300 of this disclosure can also be filled with cleaning fluid through a cleaning fluid interface provided on the frame unit 200.

[0091] Furthermore, when the frame portion 200 is provided with a cleaning liquid interface, the cleaning liquid storage portion 300 can be disposed inside the frame portion 200. In this case, the cleaning liquid storage portion 300 is not formed as at least part of the outer surface of the wet surface cleaning device.

[0092] In this disclosure, in order to clean the surface to be cleaned, the cleaning liquid storage unit 300 is connected to the cleaning head 600 at least through a cleaning liquid pipeline, thereby providing cleaning liquid to the cleaning head 600 and thus achieving wet cleaning of the surface to be cleaned.

[0093] like Figure 1 As shown, the frame portion 200 forms a receiving space, and the recycling storage portion 400 is detachably disposed on the frame portion 200 and located within the receiving space, so that when the recycling storage portion 400 contains a large amount of liquid, the user can remove the recycling storage portion 400, pour out the sewage inside, and clean up the solid waste. At this time, part of the outer surface of the recycling storage portion 400 forms part of the outer surface of the wet surface cleaning device.

[0094] In order to recover the liquid after cleaning the surface, the recovery storage unit 400 can be connected to the cleaning head 600 through the recovery pipe 401. Accordingly, the mixture of sewage and gas (dirt) can be recovered to the recovery storage unit 400 through the recovery pipe 401.

[0095] Accordingly, the wet surface cleaning equipment also includes a suction device (not shown in the figure), wherein the suction device is capable of generating negative pressure and providing this negative pressure to the recovery storage unit 400, thereby achieving forced flow of gas and wastewater within the recovery pipeline 401. In this disclosure, the gas discharged from the suction device can flow to the outside of the wet surface cleaning equipment through gaps on a portion of the outer surface of the wet surface cleaning equipment.

[0096] The frame portion 200 is connected to the cleaning head 600 via the connecting portion 500, thereby making the frame portion 200 pivotally connected to the cleaning head 600. In this disclosure, the frame portion 200 has at least two rotational degrees of freedom relative to the cleaning head 600, thereby enabling the user to operate the wet surface cleaning equipment more conveniently.

[0097] The structure of the cleaning head 600 will be explained in detail below with reference to the accompanying drawings.

[0098] Figure 2 This is a schematic diagram of the cleaning head of a wet surface cleaning device according to one embodiment of the present disclosure. Figure 3 This is a structural schematic diagram of the cleaning head of a wet surface cleaning device according to one embodiment of the present disclosure from another angle. Figures 4 to 6 This is a schematic diagram of a portion of the structure of the cleaning head of a wet surface cleaning device according to one embodiment of the present disclosure.

[0099] In this disclosure, such as Figures 2 to 6 As shown, the cleaning head 600 may include components such as a housing 610, a suction nozzle 620, a first stirring element 630, a cover 640, and a side cleaning assembly 660.

[0100] The housing 610 is configured to be connected to the frame portion 200 via a connecting portion 500, and the housing 610 is adaptable to move on the floor surface to be cleaned. For example, the housing 610 may include two rollers, and the movement of the rollers on the surface to be cleaned causes the housing 610 to move on the surface to be cleaned.

[0101] The housing 610 defines a receiving cavity for the cleaning head, which is located in the front half of the cleaning head (with the direction of movement of the wet surface cleaning device when cleaning the surface to be cleaned as the front) so as to accommodate the first stirring member 630, which is also located in the front half of the cleaning head.

[0102] like Figure 4 As shown, a suction nozzle 620 is formed on the housing 610. In this disclosure, the suction nozzle 620 is disposed adjacent to the first stirring member 630 and located behind the first stirring member 630. In this disclosure, the suction nozzle 620 is connected to the recovery pipeline 401 and forms the starting point of the recovery path.

[0103] The first agitator 630 is configured to agitate the floor surface to be cleaned; that is, when the wet surface cleaning equipment is performing a cleaning operation or a self-cleaning operation, the first agitator 630 can be driven by the first motor 650 to rotate, thereby enabling the first agitator 630 to make frictional contact with the floor surface to be cleaned and achieving cleaning of the floor surface. During the frictional contact between the first agitator 630 and the floor surface to be cleaned, cleaning liquid can be supplied to the first agitator 630, thereby achieving wet cleaning of the floor surface to be cleaned.

[0104] In one embodiment, the first motor 650 may be disposed in the housing 610 and drive the first stirring element 630 to rotate via a synchronous belt drive (i.e., operably connected to the first motor 650); in another embodiment, the first motor 650 may be disposed in the first stirring element 630 and be able to drive the first stirring element 630 to rotate; in this disclosure, the first stirring element 630 is capable of rotating along a first axis; more preferably, the first axis may be a horizontal straight line in the transverse direction, the transverse direction being the direction perpendicular to the front-back direction; the front-back direction is the direction of movement of the surface cleaning device when cleaning the surface to be cleaned.

[0105] The cover 640 is disposed on the housing 610 and configured to partially surround the first stirring member 630; in one embodiment, the cover 640 is also formed as part of the receiving cavity. In other words, the cover 640 and the housing 610 together form the aforementioned receiving cavity.

[0106] The side cleaning assembly 660 is detachably connected to the housing 610 and is located at least partially below the housing 610; that is, at least a portion of the side cleaning assembly 660 is located below the housing 610 and is able to contact the surface to be cleaned so that the side cleaning assembly 660 can also clean the surface to be cleaned.

[0107] Figure 7 This is a schematic diagram of the independent structure of a side cleaning assembly according to one embodiment of the present disclosure. Figure 8 This is a schematic diagram of the structure of a second motor according to one embodiment of the present disclosure.

[0108] More specifically, the side cleaning assembly 660 may include components such as a second motor 661, a second agitator 662, an opening 666B, and a scraper 666C.

[0109] In this disclosure, the second motor 661 is disposed in the housing 610 and is used to provide a second driving force; in a preferred embodiment, the second motor 661 may be formed inside the housing 610, thereby effectively preventing liquid from damaging the second motor 661 and improving the cleaning efficiency of the wet surface cleaning equipment.

[0110] More preferably, the second motor 661 may be connected to a reducer 665 and connected to a second agitator 662 through the reducer 665, so that the second agitator 662 has a suitable rotation speed and is conducive to cleaning the surface to be cleaned.

[0111] The second stirring element 662 is operably connected to the second motor 661. More specifically, the second stirring element 662 is operably connected to the output shaft of the reducer 665, thereby enabling the second motor 661 to drive the second stirring element 662 to rotate.

[0112] More specifically, the output shaft of the reducer 665, i.e. the rotating component of this disclosure, in one embodiment, the second motor 661 and the reducer 665 can be disposed inside the housing 610; of course, the second motor 661 and the reducer 665 can also be disposed outside the housing 610. In this disclosure, the second motor 661 and the reducer 665 are described as being located inside the housing 610.

[0113] At this time, the lower surface of the housing 610 is formed into a recessed area, and at least a portion of the cleaning base 666 and the second stirring member 662 are located within the recessed area. Furthermore, the output shaft of the rotating member, i.e., the reducer 665, can pass through the housing 610, and at least a portion of it is located below the housing 610.

[0114] More preferably, the cleaning base 666 is configured to be substantially parallel to the surface to be cleaned; correspondingly, the second agitator 662 is tilted.

[0115] Accordingly, the second stirring element 662 can be detachably connected to the rotating component via connector 667 and driven to rotate by the rotating component.

[0116] Furthermore, at least a portion of the outer edge of the second stirring member 662 protrudes from the side wall of the housing 610 and is located outside the housing 610 of the cleaning head. That is, in the lateral direction, at least a portion of the second stirring member 662 extends to the outside of the housing 610, thereby enabling the second stirring member 662 to clean components such as corners that cannot be cleaned by existing wet surface cleaning equipment.

[0117] In other words, whether the housing 610 operates close to the wall or not, the second agitator 662 can clean the corners of the wall, solving the technical problem mentioned in the background art. In this case, the second agitator 662 can also be referred to as a side brush.

[0118] In this disclosure, the second agitator 662 is configured to rotate along a second axis; wherein the second axis is inclined; in this disclosure, the second axis has an angle of 5-20° with the vertical axis (for example, the cleaning head of the wet surface cleaning device is positioned on a generally horizontal surface to be cleaned), and such that the portion of the second agitator 662 extending to the side wall of the housing 610 contacts the surface to be cleaned. In other words, the second agitator is configured to be inclined inward at 5-20° relative to the lateral direction of the cleaning head of the wet surface cleaning device.

[0119] In other words, the second shaft is not vertically arranged. As a result, the second stirring member 662, located outside the housing 610 of the cleaning head of the wet surface cleaning device, can contact the surface to be cleaned. Correspondingly, the cleaning base 666 and other components do not contact the surface to be cleaned. In other words, there is a preset distance between the cleaning base 666 and the surface to be cleaned.

[0120] Given that the first axis is a horizontal axis, the first axis and the second axis form a non-right angle, that is, the first axis and the second axis are not perpendicular.

[0121] Figure 9 This is a schematic diagram of the structure of the second stirring member and the cleaning base according to one embodiment of the present disclosure; Figure 10 This is a schematic diagram of the structure of a cleaning base according to one embodiment of the present disclosure. Figure 11 This is a structural schematic diagram of a cleaning base according to one embodiment of the present disclosure from another angle.

[0122] The second agitator 662 may include a hub 662A, a cleaning base 662B, and a side cleaning component 662C.

[0123] The hub 662A can be made of engineering plastics and other materials and has a certain degree of hardness, so the hub 662A will not easily deform. In one embodiment, the hub 662A includes a disc and a rod component disposed at the center of the disc. The rod component can be detachably inserted into the output shaft of the reducer 665, so the hub 662A can be detached from the reducer 665. Correspondingly, the second stirring member 662 can also be detached from the reducer 665.

[0124] The cleaning component base 662B is disposed on the outer side of the hub 662A, and the cleaning component base 662B has a certain radial dimension. The hardness of the cleaning component base 662B is less than that of the hub 662A. Accordingly, compared with the hub 662A, the cleaning component base 662B is more prone to deformation. In a preferred embodiment, the cleaning component base 662B can be made of materials such as rubber or silicone, thereby enabling the cleaning component base 662B and the side cleaning component 662C to jointly apply a positive pressure to the surface to be cleaned.

[0125] The side cleaning member 662C can be formed in the form of a velvet cloth and can be disposed on the outside of the cleaning member base 662B. In this disclosure, the side cleaning member 662C can be sleeved on the outside of the cleaning member base 662B and is at least partially located at the lower part of the cleaning member base 662B, so that the surface to be cleaned, such as cleaning corners, can be cleaned by the side cleaning member 662C.

[0126] In this disclosure, the side cleaning assembly 660 includes a cleaning base 666. In one embodiment, the cleaning base 666 can be detachably fixed to the housing 610. For example, the cleaning base 666 can be fixed to the housing 610 by screws. When it is necessary to disassemble the cleaning base 666, the screws are removed, thereby realizing the disassembly of the cleaning base 666.

[0127] The cleaning base 666 includes a semi-enclosed cleaning chamber, and at least a portion of the outer edge of the side cleaning member 662C is located within the semi-enclosed cleaning chamber; moreover, since the cleaning base 666 can be detached from the housing 610, the second stirring member 662 can also be detached; that is, the cleaning base 666 and the second stirring member 662 can be detached from the cleaning head as a complete unit.

[0128] like Figure 10 and Figure 11 As shown, the cleaning base 666 may include structures such as a housing 666A, an opening 666B, a scraper 666C, and a water outlet 666D.

[0129] Although the cleaning base 666 is divided into multiple parts in this disclosure, those skilled in the art should know that the cleaning base 666 can be integrally molded; for example, the cleaning base 666 can be made of plastic material and integrally molded by injection molding or compression molding.

[0130] The outer casing 666A at least partially defines a semi-enclosed cleaning chamber for accommodating at least a portion of the second stirring member 662; specifically, the outer casing 666A may include an upper member 6A1, a lower member 6A2, and a connecting member 6A3; wherein the upper member 6A1 is disposed adjacent to the lower surface of the casing 610 and can be fixed to the casing 610; in one embodiment, the upper member 6A1 is formed as a flat plate and may be fan-shaped overall.

[0131] The lower component 6A2 is spaced apart from the upper component 6A1; correspondingly, the lower component 6A2 is also configured as a plate structure, and can also be formed into a fan shape overall; the connecting component 6A3 is used to connect the upper component 6A1 and the lower component 6A2, and the upper component 6A1, the lower component 6A2, and the connecting component 6A3 together enclose the semi-enclosed clean chamber. At this time, the connecting component 6A3 is generally arc-shaped and has a roughly uniform thickness, so that the inner surface of the connecting component 6A3 can also be arc-shaped, so that there is a gap between the circumferential surface of the second stirring member 662 and the inner surface of the connecting component 6A3, that is, the connecting component 6A3 does not affect the rotation of the second stirring member 662.

[0132] The opening 666B is defined by at least a portion of the outer casing 666A; preferably, the opening 666B is disposed on the connecting member 6A3 and located approximately at the center of the circumference of the connecting member 6A3. Those skilled in the art will understand that, although not shown in the figures, the opening 666B may also be disposed on the lower member 6A2.

[0133] The lower edge of the opening 666B is flush with or lower than the inner surface of the lower component 6A2, thereby facilitating the suction of liquid and solid waste and other dirt on the inner surface of the lower component 6A2 to the opening 666B, and further suctioned to the recycling storage unit 400 through the opening 666B, where it is stored.

[0134] At least a portion of the scraper 666C is located within the semi-enclosed cleaning chamber and is positioned adjacent to the opening 666B; wherein the scraper 666C is configured to interfere with the second agitator 662, thereby enabling the scraper 666C to scrape away dirt (including sewage and solid waste) from the lower surface of the second agitator 662. Correspondingly, the proximity of the scraper 666C to the opening 666B also facilitates the entry of dirt into the opening 666B.

[0135] In one specific embodiment, the scraper 666C is disposed on the inner surface of the lower component 6A2 and extends into the interior of the semi-enclosed cleaning chamber by a predetermined height. That is, the scraper 666C extends a predetermined distance toward the upper component 6A1, thereby protruding from the inner surface of the lower component 6A2. Thus, when the second stirring member 662 rotates, its lower surface will not contact the lower component 6A2, but will only contact the scraper 666C.

[0136] More specifically, the scraper 666C includes an elongated scraper blade arranged in the radial direction of the second agitator 662, thereby enabling the scraper blade to have a shorter length.

[0137] like Figure 11 As shown, at least a portion of one end of the scraper 666C is connected to the inner surface of the connecting member 6A3, thereby giving the scraper 666C high strength and making it less prone to damage. In addition, the scraper 666C includes a notch 6C1, the inner wall of the notch 6C1, the connecting member 6A3, and the lower member 6A2 together define a fluid flow through-hole. That is, cleaning liquid on the other side of the scraper 666C (the opening 666B is located on one side of the scraper 666C) can enter the opening 666B through the fluid flow through-hole and be collected by the opening 666B.

[0138] In this disclosure, along the rotation direction of the second stirring member 662, the scraper 666C is located downstream of the opening 666B, thereby making it easy for the opening 666B to collect the dirt scraped off by the scraper 666C.

[0139] The outlet 666D is formed above the outer shell 666A and is used to provide cleaning liquid to the second agitator 662 in the semi-enclosed cleaning chamber. Furthermore, the cleaning liquid can be provided to the side cleaning member 662C of the second agitator 662, so that it can be poured through the side cleaning member 662C to clean dirt on the surface to be cleaned.

[0140] More preferably, along the rotation direction of the second agitator 662, the outlet 666D is located downstream of the scraper 666C; thus, after the dirty water on the second agitator 662 is cleaned, cleaning liquid is provided again, and correspondingly, the second agitator 662 has higher floor cleaning efficiency.

[0141] In this disclosure, the opening 666B is in fluid communication with the suction device of the wet surface cleaning equipment; more specifically, the opening 666B is connected to the recovery pipe 401 through the suction pipe 663, thereby introducing the negative pressure in the recovery pipe 401 into the semi-enclosed cleaning chamber to achieve suction of dirt in the semi-enclosed cleaning chamber. Correspondingly, fluid communication is also achieved between the opening 666B and the suction nozzle 620 of the cleaning head, wherein the suction pipe 663 is configured to form a gas passage between the opening 666B and the suction device of the wet surface cleaning equipment.

[0142] In one embodiment, the side cleaning assembly 660 further includes a side fluid distributor 664 configured to deliver cleaning liquid to the second agitator 662. In one embodiment, the side fluid distributor 664 may be the aforementioned outlet 666D, in which case it can be considered that the side fluid distributor 664 is located on the side cleaning assembly. In another embodiment, the side fluid distributor 664 may be formed as a water outlet pipe or nozzle structure, which can be disposed on the housing 610 and at least partially protrude from the housing 610 and is located below the housing 610, and the outlet of the side fluid distributor 664 is located above the second agitator 662, thereby enabling the side fluid distributor 664 to provide cleaning liquid to the second agitator 662.

[0143] More preferably, along the rotation direction of the second agitator 662, the outlet of the side fluid distributor 664 is located downstream of the scraper 666C. Accordingly, cleaning liquid is supplied to the second agitator 662 after the dirt on the second agitator 662 has been cleaned. For example, the portion of the outer edge of the side cleaning member 662C located within the semi-enclosed cleaning chamber interferes with the scraper 666C, thereby allowing the side cleaning member 662C to be cleaned by the scraper 666C.

[0144] In one embodiment, the cleaning head of the wet surface cleaning device may include a cleaning fluid pump 690, and the side fluid distributor 662 is connected to the cleaning fluid storage section 300 of the wet surface cleaning device so that the cleaning fluid in the cleaning fluid storage section 300 can be provided to the second stirring member 662 through the side fluid distributor 662; more preferably, the side fluid distributor 662 is connected to the cleaning fluid storage section 300 through the aforementioned cleaning fluid pump 690, so that the cleaning fluid is pressurized by the cleaning fluid pump 690 and provided to the second stirring member 662.

[0145] In this disclosure, the cleaning fluid pump 690 can be a peristaltic pump, thereby enabling control over whether to supply cleaning fluid to the second stirring member 662 by controlling the start-up, shutdown, and rotation speed of the cleaning fluid pump 690, and controlling the amount of cleaning fluid supplied to the second stirring member 662 when it is supplied.

[0146] In one implementation, the cleaning fluid pump 690 can be a single pump, capable of supplying cleaning fluid to both the first stirring member 630 and the second stirring member 662. In another implementation, the cleaning fluid pump 690 can be configured as two pumps, including a first cleaning fluid pump and a second cleaning fluid pump. Both the first and second cleaning fluid pumps are connected to the cleaning fluid storage unit, and the first cleaning fluid pump is used to supply cleaning fluid to the first stirring member 630, while the second cleaning fluid pump is used to supply cleaning fluid to the second stirring member 662.

[0147] In this disclosure, such as Figure 9 As shown, the hub 662A of the second agitator 662 includes a gap through which cleaning liquid is distributed to the side cleaning member 662C. In one specific embodiment, the hub 662A includes a plurality of arms (radially extending) extending outward from the axis of rotation, wherein the gap is defined between the plurality of arms, thereby allowing the cleaning liquid to flow through the gap of the hub 662A to the side cleaning member 662C located at the lower part of the hub 662A when cleaning liquid is supplied to the hub 662A.

[0148] Of course, the side fluid distributor can also directly supply cleaning liquid to the part of the side cleaning component 662C located above the base 662B of the cleaning component, and through the water absorption of the side cleaning component 662C, the cleaning liquid is adsorbed to the lower part of the side cleaning component 662C, that is, adsorbed to the side cleaning component 662C located outside and below the base 662B of the cleaning component.

[0149] According to another aspect of this disclosure, a wet surface cleaning device is provided, which includes the cleaning head of the aforementioned wet surface cleaning device. Furthermore, the wet surface cleaning device can be a handheld cleaning device.
