Description

Technical Field

[0001] The present disclosure relates to a base station and a surface cleaning system. Background Art

[0002] What is 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 provide a cleaning liquid to the surface to be cleaned, so that the surface to be cleaned is wetted, and then through the frictional contact between the stirring member of the floor brush assembly 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 recovery storage part as the contaminated cleaning liquid.

[0004] Generally speaking, a wet surface cleaner usually includes: a cleaning liquid storage part for containing a cleaning solution; a recovery storage part for recovering contaminants recovered from the floor to be cleaned; a motor-driven vacuum source to form a vacuum flow path from the floor to be cleaned to the recovery storage part; a rechargeable battery to provide energy for each component; and a base station for charging the wet surface cleaner and post-cleaning maintenance.

[0005] Some wet surface cleaners in the prior art can provide foam to the surface to be cleaned, thereby enabling the surface to be cleaned more efficiently. Among them, the foam is a mixture of a cleaning liquid and a cleaning agent.

[0006] However, the foam nozzle of the existing wet surface cleaner has a fixed spraying direction, that is, the foam can only be used when the wet surface cleaner cleans the surface to be cleaned. When the wet surface cleaner performs self-cleaning, the foam cannot be provided to the stirring member of the wet surface cleaner, reducing the self-cleaning effect of the wet surface cleaner.

[0007] Therefore, it is urgent to develop a base station and a surface cleaning system, and enable the foam provided by the surface cleaning device of the surface cleaning system to be used for the self-cleaning of the surface cleaning device. Summary of the Utility Model

[0079] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and implementation manners. It can be understood that the specific implementation manners 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.

[0080] It should be noted that, without conflict, the implementation manners and features in the present disclosure 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 in conjunction with the implementation manners.

[0081] Unless otherwise specified, the exemplary implementation manners / embodiments 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 implementation manners / embodiments can be additionally combined, separated, interchanged, and / or rearranged.

[0082] In the drawings, cross-hatching and / or shading are generally used to make the boundaries between adjacent components clear. Thus, unless stated otherwise, the presence or absence of cross-hatching or shading does not convey or imply any preference or requirement regarding the specific material, material properties, dimensions, proportions, commonality between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the drawings, for clarity and / or descriptive purposes, the dimensions and relative dimensions of components may be exaggerated. When an exemplary embodiment can be implemented differently, the specific process order may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in an order opposite to that described. In addition, the same reference numerals denote the same components.

[0083] 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 may 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. For this reason, the term "connected" can refer to a physical connection, an electrical connection, etc., and can have or not have intervening components.

[0084] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "down", "above", "on", "over", "upper", and "side (e.g., as in "sidewall")" to describe the relationship of one component to another (other) component as shown in the 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 manufacturing. For example, if the device in the drawings is flipped, a component described as being "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. In addition, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted.

[0085] 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 dictates otherwise, the singular forms "a", "an" and "the" are also intended to include the plural forms. Further, when the terms "comprise" and / or "include" and their variants are used in this specification, it is stated that the stated features, integers, steps, operations, components, assemblies and / or groups thereof exist, but do not preclude the existence 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 measured, calculated and / or provided values that would be recognized by a person of ordinary skill in the art.

[0086] Figure 1 is a schematic structural diagram of a surface cleaning system according to an embodiment of the present disclosure.

[0087] As Figure 1 and Figure 2 shown, the present disclosure provides a surface cleaning system, which includes a surface cleaning device and a base station 900.

[0088] The surface cleaning device is arranged to be able to clean a surface to be cleaned (such as a floor surface, etc.). Preferably, the surface cleaning device is able to perform wet cleaning on the surface to be cleaned, that is, it is formed as a wet surface cleaning device, and the liquid after cleaning the surface to be cleaned is recovered to the surface cleaning device.

[0089] The base station 900 is arranged for the surface cleaning device to dock and is able to supply electrical energy to the surface cleaning device to charge the rechargeable battery of the surface cleaning device.

[0090] More preferably, the base station 900 is further able to supply hot air to the surface cleaning device to dry the stirring member 620 of the surface cleaning device through the hot air, so that after the stirring member 620 is self-cleaned, the residual water on the stirring member 620 can be removed to prevent the stirring member 620 from generating an odor.

[0091] The present disclosure first details the structure of the surface cleaning device and then details the structure of the base station 900 hereinafter.

[0092] Figure 2 is a schematic structural diagram of a surface cleaning device according to an embodiment of the present disclosure.

[0093] As Figure 1 and Figure 2As shown, the surface cleaning device may include components such as a handle portion 100, a frame portion 200, a cleaning liquid storage portion 300, a recycling storage portion 400, a connecting portion 500, and a floor brush assembly 600.

[0094] When the surface cleaning device of the present disclosure is in use, the floor brush assembly 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 floor brush assembly 600.

[0095] The handle portion 100 is used to operate the surface cleaning device. More specifically, on the one hand, the operator can control the attitude of the surface cleaning device by operating the handle portion 100. For example, when the frame portion 200 of the surface cleaning device is in an inclined state (i.e., at an angle of approximately 60° with the surface to be cleaned) or a substantially lying flat state (i.e., substantially parallel to the surface to be cleaned), the surface cleaning device can be in a cleaning mode and can clean the surface to be cleaned; when the frame portion 200 of the surface cleaning device is in a vertical state, at this time the surface cleaning device can be in a stopped working state, or when the surface cleaning device is docked at the base station 900, the frame portion 200 of the surface cleaning device is also substantially in a vertical state; on the other hand, physical buttons can be provided on the handle portion 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., so as to make the user experience of the surface cleaning device better.

[0096] The handle portion 100 can be arranged at the upper end of the frame portion 200, so as to be able to operate the surface cleaning device by operating the handle portion 100. In the present disclosure, the frame portion 200 is formed as the main force-bearing structure of the surface cleaning device, and both the cleaning liquid storage portion 300 and the recycling storage portion 400 of the surface cleaning device can be directly or indirectly fixed to the frame portion 200.

[0097] The cleaning liquid storage portion 300 is formed in the shape of a box to store cleaning liquid in the cleaning liquid storage portion 300. In one embodiment, the cleaning liquid can be pure water. Of course, those skilled in the art should know that a mixture of pure water and a cleaning agent, etc. can also be stored in the cleaning liquid storage portion 300.

[0098] An accommodation space is formed on the frame portion 200, and the cleaning liquid storage portion 300 can be arranged in the accommodation 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.

[0099] In the present disclosure, the cleaning liquid storage unit 300 can be detached from the frame unit 200 and filled with cleaning liquid manually by the user. Of course, the cleaning liquid storage unit 300 of the present disclosure can also be filled with the cleaning liquid of the cleaning liquid storage unit 300 through the cleaning liquid interface provided on the frame unit 200.

[0100] Furthermore, when a cleaning liquid interface is provided on the frame unit 200, the cleaning liquid storage unit 300 can be disposed inside the frame unit 200. At this time, the cleaning liquid storage unit 300 does not form at least part of the outer surface of the surface cleaning device.

[0101] In the present disclosure, to achieve the cleaning of the surface to be cleaned, the cleaning liquid storage unit 300 is at least connected to the floor brush assembly 600 through a cleaning liquid pipeline, so as to supply the cleaning liquid to the floor brush assembly 600. On the one hand, the surface to be cleaned can be directly cleaned with the cleaning liquid. On the other hand, the cleaning liquid can also be mixed with a cleaning agent, etc. to form foam, and the surface to be cleaned can be cleaned with the foam.

[0102] As Figure 1 shown, the frame unit 200 forms a receiving space. The recycling storage unit 400 is detachably disposed on the frame unit 200 and is located in the receiving space. When there is a large amount of liquid stored in the recycling storage unit 400, the user can remove the recycling storage unit 400, pour out the sewage inside and clean up the solid waste. At this time, part of the outer surface of the recycling storage unit 400 forms part of the outer surface of the surface cleaning device.

[0103] To recycle the liquid after cleaning the surface to be cleaned, the recycling storage unit 400 can be connected to the floor brush assembly 600 through a recycling pipeline. Accordingly, a mixture of sewage and gas (dirty) can be recycled to the recycling storage unit 400 through the recycling pipeline.

[0104] Accordingly, the surface cleaning device further includes a vacuum pumping device (not shown in the figure). Among them, the vacuum pumping device can generate negative pressure and provide the negative pressure to the recycling storage unit 400, so as to realize the forced flow of gas and sewage in the recycling pipeline. In the present disclosure, the gas discharged from the vacuum pumping device can flow to the outside of the surface cleaning device through the gaps on part of the outer surface of the surface cleaning device.

[0105] The frame unit 200 is connected to the floor brush assembly 600 through the connecting part 500, so that the frame unit 200 is pivotally connected to the floor brush assembly 600. In the present disclosure, the frame unit 200 has at least two rotational degrees of freedom relative to the floor brush assembly 600, so as to enable the user to operate the surface cleaning device more conveniently.

[0106] Figure 3It is a schematic structural view of a floor brush assembly according to an embodiment of the present disclosure. Figure 4 It is a schematic structural view of another angle of the floor brush assembly according to an embodiment of the present disclosure. Figure 5 is Figure 4 An enlarged view of part A of

[0107] As Figures 3 to 5 shown, the floor brush assembly 600 of the present disclosure may include a housing 610, a stirring member 620, a suction nozzle 630, a foam generator, and a nozzle 640.

[0108] The housing 610 is configured to be connected to the frame portion 200 through the connecting portion 500, and the housing 610 is capable of moving on the surface to be cleaned. For example, the housing 610 may include two rolling wheels. The surface of the housing 610 close to the surface to be cleaned is formed as the bottom surface of the housing 610. When the surface cleaning device is cleaning the surface to be cleaned, the user can operate the surface cleaning device so that the surface cleaning device can move in the front-back direction. Among them, the forward direction is the direction in which the floor brush assembly 600 is away from the user, and correspondingly, the backward direction is the direction in which the floor brush assembly 600 is close to the user.

[0109] The housing 610 can define a suction cavity for the floor brush assembly. The suction cavity is located in the front half of the floor brush assembly 600 so as to accommodate the stirring member 620 in the suction cavity. Correspondingly, the stirring member 620 is also located in the front half of the floor brush assembly 600.

[0110] A suction nozzle 630 is formed on the housing 610. In the present disclosure, the suction nozzle 630 is disposed adjacent to the stirring member 620 and is located behind the stirring member 620. In the present disclosure, the suction nozzle 630 is connected to a recovery pipeline and is formed as the starting point of the recovery path. That is to say, the suction nozzle 630 of the present disclosure can communicate with the recovery storage portion 400 of the surface cleaning device.

[0111] The stirring member 620 is configured to stir the surface to be cleaned; that is to say, when the surface cleaning device is performing a cleaning operation or a self-cleaning operation, the stirring member 620 can be driven by a motor to rotate. Thus, the stirring member 620 can make frictional contact with the surface to be cleaned, that is, the stirring member 620 can cooperate with the cleaning medium to scrub the surface to be cleaned to achieve the cleaning of the surface to be cleaned. During the frictional contact between the stirring member 620 and the surface to be cleaned, a cleaning liquid can be provided to the stirring member 620 or the surface to be cleaned near the stirring member 620, so as to achieve the wet cleaning of the surface to be cleaned.

[0112] That is to say, the surface cleaning device of the present disclosure may include a liquid dispenser that can supply cleaning liquid to the stirring member 620 or the surface to be cleaned near the stirring member 620. In a specific embodiment, the liquid dispenser may include a liquid supply pump that can extract the cleaning liquid from the cleaning liquid storage portion 300, pressurize the cleaning liquid, and supply it to the liquid outlet component, and supply the pressurized cleaning liquid to the stirring member 620 or the surface to be cleaned near the stirring member 620 through the liquid outlet component.

[0113] In the present disclosure, the liquid outlet component may be formed in the form of a nozzle. Of course, it may also be formed in the form of a water spray hole on the housing 610, and details are not described herein one by one.

[0114] The foam generator is used to generate foam. In the present disclosure, the foam generator can generate foam by mixing the cleaning liquid stored in the cleaning liquid storage portion 300 and the cleaning agent stored in the container storing the cleaning agent. In a preferred embodiment, the foam generator can be connected to the liquid dispenser so as to supply the cleaning liquid to the foam generator through the liquid dispenser.

[0115] The foam generator of the present disclosure may be disposed within the housing 610. In another embodiment, the foam generator can also be disposed within the frame portion 200 and communicate with the nozzle 640 through a foam delivery pipeline.

[0116] The nozzle 640 delivers the foam generated by the foam generator outward; wherein, the nozzle 640 can rotate between a first operable position and a second operable position. The first operable position is that the nozzle 640 faces the plane where the bottom surface of the floor brush assembly 600 is located and is substantially perpendicular thereto, and the second operable position is that the nozzle 640 faces the plane where the bottom surface of the floor brush assembly 600 is located and forms a first angle α therewith, and the first angle is less than 90°.

[0117] In one case, as Figure 4 and Figure 5 shown, when the surface cleaning device is cleaning the surface to be cleaned, the surface to be cleaned may be a flat surface. Correspondingly, the bottom surface of the housing 610 can be parallel or substantially parallel to the surface to be cleaned. At this time, the nozzle 640 needs to supply foam to the surface to be cleaned. Therefore, the nozzle 640 needs to be arranged facing the surface to be cleaned, that is, the nozzle 640 needs to be arranged to face the plane where the bottom surface of the floor brush assembly 600 is located and be substantially perpendicular thereto. That is to say, the first operable position is the position of the nozzle 640 when the surface cleaning device is cleaning on the surface to be cleaned.

[0118] Figure 6 is a schematic structural diagram of the floor brush assembly docked at the base station according to an embodiment of the present disclosure.

[0119] In another case, as Figure 6 shown, when the surface cleaning device docks at the base station 900 for self-cleaning, that is, when self-cleaning the stirring member 620, the nozzle 640 needs to supply foam to the stirring member 620, so as to be able to clean the stirring member 620 more thoroughly. In other words, the second operable position is the position of the nozzle 640 when performing maintenance on the base station 900. At this time, the nozzle 640 faces the plane where the bottom surface of the floor brush assembly 600 is located and forms a first angle with it, and the first angle is less than 90°. Thus, the nozzle 640 is arranged to face the stirring member 620.

[0120] That is to say, when the nozzle 640 is located at the second operable position, along the direction from top to bottom, the nozzle 640 is arranged to be close to the axis of the stirring member 620. Thus, when the value of the first angle is relatively large, the foam provided by the nozzle 640 can be provided into the cleaning tank 923 of the base station 900. Moreover, when the surface cleaning device is performing self-cleaning, its stirring member 620 is also located in the cleaning tank 923, and the stirring member 620 can be driven to rotate. Correspondingly, the foam in the cleaning tank 923 can cover the entire stirring member 620, so as to clean the stirring member 620 with the cleaning agent in the foam.

[0121] On the other hand, when the value of the first angle is relatively small, the nozzle 640 is arranged to face the stirring member 620. Thus, the foam provided by the nozzle 640 can be directly provided onto the stirring member 620. Further, since the nozzle 640 can continuously supply foam, correspondingly, as the stirring member 620 rotates, the foam can cover the entire stirring member 620, so as to clean the stirring member 620 with the cleaning agent in the foam.

[0122] In a preferred embodiment, the first angle is 10 - 85°. Correspondingly, within the range of this first angle, the nozzle 640 can only supply foam to the cleaning tank 923 or the stirring member 620, and will not supply foam to other components, thereby improving the utilization efficiency of the foam. That is to say, when providing the same amount of foam (for example, the foam generator is controlled and operates at a preset power for a preset time), the cleaning effect of the stirring member 620 is improved.

[0123] Figure 7 It is a partial structural schematic diagram of a floor brush assembly according to an embodiment of the present disclosure. Figure 8 It is Figure 7 an enlarged schematic view of part B of Figure 9 It is a structural schematic diagram of a rotating bracket and a nozzle according to an embodiment of the present disclosure. Figure 10 It is a structural schematic diagram of the rotating bracket and the nozzle from another angle according to an embodiment of the present disclosure. Figure 11Schematic structural diagram of a rotating bracket according to an embodiment of the present disclosure. Figure 12 Schematic structural diagram of a nozzle according to an embodiment of the present disclosure.

[0124] The rotation of the nozzle 640 between the first operable position and the second operable position is achieved by the rotating bracket 650; that is, the nozzle 640 of the present disclosure can be mounted on the rotating bracket 650. Thus, when the rotating bracket 650 rotates, the notch of the nozzle 640 can have different orientations. Correspondingly, the nozzle 640 can be in the first operable position or the second operable position.

[0125] In a specific embodiment, as Figure 12 shown, the nozzle 640 of the present disclosure can supply the foam (cleaning foam) generated by the foam generator to the surface to be cleaned, or directly or indirectly provide the foam generated by the foam generator to the stirring member 620. More preferably, the foam generator can generate high-pressure foam, or the foam generated by the foam generator can be pressurized by a peristaltic pump and then provided to the nozzle 640, and these high-pressure foams are ejected from the nozzle 640 at a high speed, so that the foam has a large coverage area.

[0126] Structurally, the nozzle 640 includes a first main body 641 and a second main body 642 connected to each other; wherein, the first main body 641 and the second main body 642 can be integrally formed or separately formed and are installed or fixed together.

[0127] In the present disclosure, the first main body 641 is formed as a hemispherical thin-walled part, so that the interior of the first main body 641 forms a hemispherical buffer cavity, that is, the outer surface of the first main body 641 is a hemispherical surface. Correspondingly, the inner surface of the first main body 641 is a hemispherical surface, whereby the first main body 641 has a generally uniform wall thickness as a whole.

[0128] At least a part of the second main body 642 is formed in a cylindrical shape. For example, the end of the second main body 642 connected to the first main body 641 is formed in a generally cylindrical shape. In the present disclosure, preferably, the outer diameter (diameter) of the cylindrical part of the second main body 642 is the same as the diameter of the outer surface of the first main body 641.

[0129] The second main body 642 includes a conveying channel for conveying foam, and the conveying channel communicates with the hemispherical buffer cavity; the conveying channel is formed in a cylindrical shape, and the inner diameter (diameter) of the conveying channel is the same as the diameter of the inner surface of the first main body 641, so that the foam has as little resistance as possible during the conveying process.

[0130] The nozzle 640 further includes a cut 643 through which foam is supplied to the surface to be cleaned; in a specific embodiment, the cut 643 is arranged to extend transversely through the first body 641 and communicate with the hemispherical buffer cavity, so that after the foam detaches from the cut 643, a fan-shaped radiation surface is formed.

[0131] That is to say, when machining the cut 643 of the first body 641, a groove with a certain width and a certain depth can be cut from the vertex of the first body 641 towards the center of the sphere. When the nozzle 640 is installed on the rotating bracket 650, it is only necessary to keep the cut 643 arranged in the transverse direction or approximately in the transverse direction. Wherein, the transverse direction is the axial direction of the stirring member 620.

[0132] In a more preferred embodiment, at least a part of the cut 643 extends to the second body 642, that is to say, at least a part of the second body 642 is formed with a groove, and the groove is formed as a part of the cut 643.

[0133] At this time, the inner diameter of the delivery channel is smaller than the projection length of the cut 643 on the cross-section of the delivery channel, whereby the cut 643 can have a maximum foam radiation area.

[0134] In a preferred solution, when the nozzle 640 is in the first operable position, there is a first distance between the cut 643 of the nozzle 640 and the surface to be cleaned; when the nozzle 640 is in the second operable position, there is a second distance between the cut 643 of the nozzle 640 and the inner wall surface of the cleaning tank 923, or there is a third distance between the cut 643 of the nozzle 640 and the outer surface of the stirring member 620; in the present disclosure, when the first distance is greater than the second distance, the second distance is greater than the third distance.

[0135] Thus, when foam with pressure is supplied to the nozzle 640, the pressure of the foam can be changed according to the position of the nozzle 640, so that the nozzle 640 can supply foam in the entire transverse direction of the floor brush assembly.

[0136] Specifically, when the nozzle 640 is in the first operable position, foam with a first pressure can be supplied to the nozzle 640, and after the foam is sprayed onto the surface to be cleaned, it can be formed into a linear foam, and the length of the linear foam can be approximately the same as the axial dimension of the stirring member 620 and be located in front of the stirring member 620. Thus, the linear foam can pre-wet the floor to be cleaned, and as the floor brush assembly 600 moves forward, it is dispersed by the rotating stirring member 620, so as to clean the surface to be cleaned through the foam.

[0137] When the nozzle 640 is in the second operable position, the angular value of the first angle between the nozzle 640 and the plane where the bottom surface of the floor brush assembly 600 is located can be determined first, and according to the angular value of the first angle, it can be judged whether the nozzle 640 provides foam to the inner wall surface of the cleaning tank 923 or the nozzle 640 provides foam to the outer surface of the stirring member 620; moreover, according to the angular value of the first angle, the value of the second distance or the third distance can also be obtained.

[0138] Correspondingly, the pressure of the foam can be changed according to the value of the second distance or the third distance. Specifically, when the nozzle 640 provides foam to the inner wall of the cleaning tank 923, the foam has a second pressure; when the nozzle 640 provides cleaning foam to the surface of the stirring member 620, the foam has a third pressure, wherein the first pressure is greater than the second pressure, and the second pressure is greater than the third pressure. Thus, the foam ejected by the nozzle 640 can cover the entire stirring member 620 in the lateral direction, thereby improving the cleaning effect of the stirring member 620.

[0139] The other end of the second body 642 of the nozzle 640 can be connected and fixed to the rotating bracket 650, so that the nozzle 640 can be driven to swing by the rotating bracket 650, and thus the position of the nozzle 640 of the present disclosure can be conveniently controlled.

[0140] As Figure 7 and Figure 8 shown, the housing 610 of the present disclosure includes a front end portion 611, and the front end portion 611 includes a groove portion. At least a part of the rotating bracket is located in the groove portion. Thus, the projection of the nozzle 640 on the surface to be cleaned can be in front of the projection of the stirring member 620 on the surface to be cleaned. Correspondingly, when the nozzle 640 is in the first operable position, the nozzle 640 does not directly provide foam to the stirring member 620.

[0141] In a specific embodiment, as Figure 9 and Figure 10 shown, the rotating bracket 650 may include: a base body 651 and a shaft member 652. The base body 651 is formed with a foam channel, wherein the two ends of the foam channel are respectively communicated with the foam generator and the nozzle 640; specifically, the foam channel can be communicated with the conveying channel of the nozzle 640. The base body 651 is rotatably arranged on the housing 610 through the shaft member 652; in a specific embodiment, the base body 651 and the shaft member 652 are separately arranged and can be assembled together.

[0142] In the present disclosure, through holes may be formed in two side walls in the lateral direction of the groove portion, and one end of the shaft member 652 is rotatably disposed in the through holes. Correspondingly, the other end of the shaft member 652 can be fixed to the base body 651. In a preferred embodiment, the number of the shaft members 652 is two, and in the lateral direction, the two shaft members 652 are respectively located on both sides of the base body 651. Moreover, the two shaft members 652 have the same rotation axis, and the rotation axis is parallel to the lateral direction.

[0143] Thus, the rotation bracket 650 of the present disclosure can rotate a preset angle relative to the housing 610, and correspondingly, the nozzle 640 is in different positions.

[0144] In a preferred embodiment, the base body 651 includes a first surface 651A and a second surface 651B opposite to the first surface 651A; when the nozzle 640 is in the first operable position, the first surface 651A and / or the second surface 651B can be parallel or substantially parallel to the surface to be cleaned. That is to say, at this time, the first surface 651A and the second surface 651B can be substantially parallel to the bottom surface of the housing 610.

[0145] In the height direction, the second surface 651B is located at a position higher than the first surface 651A, so that the nozzle 640 can be fixed at the first surface 651A; that is to say, the nozzle 640 of the present disclosure is located below the rotation bracket 650.

[0146] The groove portion of the housing 610 includes a limiting surface. In a preferred embodiment, since the groove portion of the housing 610 may include a top wall and two side walls, correspondingly, the top wall forms the limiting surface. When the rotation bracket 650 rotates under the restoring force of the restoring spring and the nozzle 640 rotates from the second operable position to the first operable position, the limiting surface can contact at least a part of the second surface 651B and limit the further rotation of the rotation bracket 650. Thus, the nozzle 640 is limited in the first operable position.

[0147] The base body 651 includes two support portions 651C, and the two support portions 651C are respectively located at both ends in the lateral direction of the base body 651 and extend from the second surface 651B of the base body 651 in a direction perpendicular to the lateral direction (i.e., upward). Thus, a preset distance can be formed between the second surface 651B of the base body 651 and the rotation axis of the shaft member 652. Correspondingly, the rotation bracket 650 formed by the above structure can be more conveniently installed on the housing 610.

[0148] In the present disclosure, when the nozzle 640 moves from the first operable position to the second operable position, the second surface 651B moves away from the limiting surface; that is to say, the limiting surface of the housing 610 of the present disclosure can only be used to limit the rotation of the rotating bracket 650 in one direction and does not limit the reverse rotation of the rotating bracket 650.

[0149] In the present disclosure, the base body 651 includes a force-receiving surface 651D. When a pressure is applied to the force-receiving surface 651D, the pressure causes the rotating bracket 650 to rotate and causes the nozzle 640 to rotate in a direction approaching the second operable position.

[0150] In a preferred embodiment, the force-receiving surface 651D can be formed as at least a part of the front surface of the base body 651; more preferably, a bump 651E is formed on the base body 651, and the bump 651E protrudes forward. Moreover, the front surface of the bump 651E is formed as the force-receiving surface 651D. Thus, the rotating bracket 650 of the present disclosure can be conveniently applied with a force by the force-applying surface of the actuator 930 of the base station 900, and during the process of applying a force to the rotating bracket 650, it will not touch the nozzle 640, so that the nozzle 640 will not be damaged.

[0151] In the present disclosure, a return spring 653 is provided on the shaft member 652, and the return spring 653 is used to return the rotating bracket 650 from the second operable position to the first operable position. In a specific embodiment, the return spring 653 can be a torsion spring. The base body 651 includes a stop portion 651F, and the stop portion 651F is formed as a protruding portion in the transverse direction. Thus, one end of the torsion spring can be stopped at the stop portion 651F, and the other end can be stopped at the housing 610, and the torsion spring is in a pre-compressed state. Thus, the rotating bracket 650 can be returned by the torsion spring, that is, the nozzle 640 is returned from the second operable position to the first operable position.

[0152] In other words, when the surface cleaning device leaves the base station 900, since the base station 900 can no longer apply a force to the force-receiving surface of the rotating bracket 650, the rotating bracket 650 and the nozzle 640 will return to the initial state, where the initial state is the state in which the nozzle 640 is in the first operable position.

[0153] Figure 13 It is a schematic structural diagram of a floor brush assembly docked at a base station 900 according to an embodiment of the present disclosure. Figure 14 It is a schematic structural diagram of a base station 900 according to an embodiment of the present disclosure. Figure 15 is Figure 14 an enlarged schematic view of part C of Figure 16 It is a schematic diagram of the cooperation relationship between a base station 900 and a rotating bracket according to an embodiment of the present disclosure. Figure 17 isFigure 16 The intention of magnifying part D.

[0154] As Figures 13 to 17 As shown, the base station 900 of the present disclosure is arranged to facilitate the docking of the surface cleaning device. Specifically, the base station 900 of the present disclosure includes components such as a base member 910, a tray 920, and an actuator 930.

[0155] The base member 910 is arranged to be suitably placed on the ground or other positions. And an accommodation space is formed inside the base member 910, and components such as a blower can be arranged in the accommodation space, so that a drying air flow can be formed by the blower.

[0156] Specifically, the base member 910 has an upward opening, that is, the upper end of the accommodation space is open, and the tray 920 is arranged on the base member 910 and can close the opening of the base member 910.

[0157] An air inlet is formed on the base member 910, and the air inlet is formed as the starting point of the drying air flow; at the same time, an air passage is formed between the base member 910 and the tray 920, and the blower can suck the air entering through the air inlet and discharge it to the air passage; more preferably, the tray 920 includes an air outlet 924, and the air outlet 924 is communicated with the air passage, so that the air outlet 924 can form the end point of the gas flow path. Correspondingly, the air sucked by the blower can be discharged to the outside of the base station 900 through the air outlet 924.

[0158] In a specific embodiment, a heating device can be arranged in the air passage, so that hot air can be discharged through the air outlet 924, and thus the stirring member 620 of the surface cleaning device can be dried by the hot air.

[0159] In the present disclosure, the tray 920 is configured such that when the surface cleaning device docks at the base station 900, at least a part of the tray 920 is located below the surface cleaning device.

[0160] A positioning groove 921 can be formed on the upper surface of the tray 920, and the positioning groove 921 is used to limit the position of the surface cleaning device. Specifically, by moving the rolling wheels of the surface cleaning device into the positioning groove 921, the position of the surface cleaning device relative to the base station 900 is fixed.

[0161] Moreover, in order to prevent the rolling wheels from moving out of the positioning groove, a limiting portion 922 can be arranged near the positioning groove 921, and the limiting portion 922 can prevent the movement of the rolling wheels, so that the surface cleaning device can be more stably positioned.

[0162] Preferably, the positioning groove 921 is formed as a first arc-shaped groove, and a second arc-shaped groove is also formed on the surface of the limiting portion 922 close to the positioning groove. When the surface cleaning device docks at the base station 900, both the first arc-shaped groove and the second arc-shaped groove are in contact with the rolling wheel.

[0163] Moreover, a cleaning groove 923 is formed on the upper surface of the tray 920. The shape of the cleaning groove 923 can be adapted to the shape of components such as the stirring body 620 of the surface cleaning device. When the surface cleaning device docks at the base station, the stirring body 620 of the surface cleaning device can be arranged in the cleaning groove 923.

[0164] The actuating member 930 is arranged on the tray 920 and extends along the air outlet direction of the air outlet 924 of the tray 920; in the present disclosure, the actuating member 930 is used to drive the rotating bracket 650 to rotate and make the nozzle 640 rotate from the first operable position to the second operable position. Among them, the actuating member 930 extending along the air outlet direction of the air outlet 924 does not mean that the extending direction of the actuating member 930 is exactly the same as the air outlet direction of the air outlet 924, but it is approximately the same.

[0165] That is to say, when the surface cleaning device is not docked at the base station, the nozzle 640 is in the first operable position; when the surface cleaning device is being placed on the base station, the actuating member 930 will contact the rotating bracket 650. When the surface cleaning device further descends and docks on the base station 900, under the action of the gravity of the surface cleaning device and since the actuating member 930 is immovable, the actuating member 930 will push the rotating bracket 650 to rotate.

[0166] In a preferred embodiment, in the height direction, the position of the air outlet 924 of the tray 920 is higher than that of the cleaning groove 923. Thus, the cleaning liquid can be stored in the cleaning groove 923, and the self-cleaning of the stirring member 620 of the surface cleaning device can be realized through the cleaning liquid. At this time, the cleaning liquid will not enter the air outlet 924.

[0167] In terms of the height direction, one end of the actuating member 930 is fixed to the tray 920, and this end is formed as a fixed end; in contrast, the other end of the actuating member 930 is formed as a free end, and the free end is at a higher position relative to the fixed end. That is to say, compared with the fixed end, the free end is farther from the cleaning groove 923 of the tray 920.

[0168] However, in the horizontal plane projection, that is, when the base station 900 is placed on a substantially horizontal surface to be cleaned, the actuating member 930 extends in a direction approaching the cleaning groove 923. That is to say, in one case, a part of the actuating member 930 can extend directly above the cleaning groove 923, thereby facilitating the actuating member 930 to push the rotating bracket 930 to act.

[0169] As Figure 15 shown, the actuator 930 of the present disclosure includes at least one actuator piece; wherein, when there are multiple actuator pieces, the multiple actuator pieces are arranged in parallel. In a specific embodiment, the number of the actuator pieces can be 5; correspondingly, through the multiple actuator pieces arranged in parallel, on the one hand, it is convenient for the forming of the actuator 930, and on the other hand, it can make the actuator 930 have a lighter weight on the premise of having a required strength.

[0170] In terms of position, the tray 920 of the present disclosure includes a transverse direction, and the transverse direction of the tray 920 can be the same as the transverse direction of the floor brush assembly. Correspondingly, along the transverse direction, a plurality of air outlets 924 are provided, so that through these air outlets 924, air flow can be provided to all areas of the stirring member of the surface cleaning device to prevent uneven drying of the stirring member 620.

[0171] Preferably, the actuator 930 is located at the middle position in the transverse direction of the tray 920; more preferably, a plurality of air outlets 924 are provided on both sides in the transverse direction of the actuator 930. That is to say, the actuator 930 of the present disclosure can only occupy the position of part of the air outlets 924, for example, only occupy the position of 1 air outlet 924.

[0172] The contour shape of the actuator 930 of the base station will be described below.

[0173] In the present disclosure, the actuator piece includes a first outer surface 931, and the tray 920 includes an end surface 925. The first outer surface 931 and the end surface 925 are in the same plane. Thus, when the actuator 930 and the tray 920 of the present disclosure are integrally formed, the first outer surface 931 and the end surface 925 can be manufactured synchronously, thereby improving the processing efficiency.

[0174] In addition, the actuator piece further includes a guiding surface 932. When the tray 920 is arranged substantially horizontally, the guiding surface 932 is arranged obliquely. Among them, along the direction from top to bottom, the guiding surface 932 approaches the cleaning groove 923 of the tray 920. Thus, when the surface cleaning device is being placed on the base station 900, the guiding surface 932 can first contact the rotating bracket 650 and / or the nozzle 640 to prevent the rotating bracket 650 and / or the nozzle 640 from being stuck by the actuator 930.

[0175] Specifically, the guiding surface 932 includes a first end (upper end) and a second end (lower end). Correspondingly, the first end of the guiding surface 932 is connected to the first outer surface 931. Preferably, the guiding surface 932 and the first outer surface 931 are formed into a smooth connection.

[0176] The actuator sheet further includes a force - applying surface 933, the upper end of the force - applying surface 933 is connected to the second end (i.e., the lower end) of the guiding surface 932; when the tray 920 is disposed substantially horizontally, the force - applying surface 933 is disposed obliquely, wherein, along the direction from top to bottom, the force - applying surface 933 approaches the cleaning tank 923 of the tray 920. Thus, the rotating bracket 650 can be pushed to rotate through the force - applying surface 933.

[0177] In a preferred embodiment, when the surface cleaning device is docked at the base station, the force - applying surface 933 can be in close contact with the force - receiving surface 651D of the rotating bracket and disposed substantially parallel thereto, thereby enabling the rotating bracket 650 to be stably held by the actuator 930.

[0178] More preferably, there is a first included angle between the guiding surface 932 and the horizontal plane, and a second included angle between the force - applying surface 933 and the horizontal plane. Both the first included angle and the second included angle are acute angles, and the first included angle is less than the second included angle. That is to say, the force - applying surface 933 of the present disclosure has a greater degree of inclination compared to the guiding surface 932.

[0179] In the present disclosure, the degree of inclination of the force - applying surface 933, that is, the magnitude of the second included angle, can be set according to the magnitude of the first included angle. For example, the first included angle and the second included angle have the same magnitude, so that when the nozzle 640 is in the second operable position, the force - receiving surface of the rotating bracket 650 can be substantially parallel to the force - applying surface 933.
