Description

Technical Field

[0001] The present disclosure relates to the field of cleaning technologies, and particularly to a cleaning device. Background Art

[0002] With the development of social productive forces, people's living standards have also been improved. On the premise that the material basis is guaranteed, people begin to use various tools to reduce labor and improve the quality of life, and household cleaning devices emerge as the times require. A cleaning device generally includes an upright body and a floor brush assembly provided at the bottom of the body. When in use, the user pushes and pulls the body, so that the floor brush assembly reciprocates on the working surface, thereby realizing the cleaning of the working surface.

[0003] In the prior art, a water tank is usually installed on the body, which makes the body relatively heavy and difficult for the user to push and pull. In addition, the volume capacity of the water tank in the prior art is relatively small, and the amount of water stored therein is not enough to complete a whole-house cleaning, so the user needs to return to the base station to replenish water during the cleaning process, resulting in a poor user experience. Utility Model Content

[0004] The present disclosure provides a cleaning device to solve the problems existing in the prior art.

[0005] According to a first aspect of the present disclosure, there is provided a cleaning device, including a body and a floor brush assembly, wherein the floor brush assembly includes:

[0006] A floor brush housing;

[0007] A roller brush cover, which is configured to be detachably connected to the floor brush housing according to a preset disassembly and assembly path, and is configured to enclose a roller brush cavity with the floor brush housing;

[0008] A roller brush, which is located in the roller brush cavity and is configured to be rotatably connected to the floor brush housing;

[0009] A water tank, which is detachably connected to the floor brush housing, and the water tank has a liquid storage cavity, and the liquid storage cavity is configured to extend from a position corresponding to the floor brush housing to a position on the disassembly and assembly path of the roller brush cover.

[0010] One beneficial effect of the present disclosure is that by arranging the clean water tank on the floor brush housing, the weight of the body is reduced, making it easier for the user to push the body of the cleaning device. In addition, the clean water tank arranged on the floor brush housing increases the downward pressure of the floor brush assembly, thereby improving the cleaning effect of the roller brush on the working surface. The liquid storage cavity of the clean water tank of the present disclosure extends to a position on the disassembly and assembly path of the roller brush cover, realizing that the clean water tank can be integrated with the roller brush cover on the floor brush assembly at the same time, and the capacity of the outwardly extending liquid storage cavity is also increased. The amount of water stored in the clean water tank is sufficient to complete a full-house cleaning, and the user does not need to replenish water repeatedly, improving the user experience.

[0011] Other features and advantages of the present disclosure will become clear from the following detailed description of exemplary embodiments of the present disclosure with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0042] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0043] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0044] It should be noted that like reference numerals and letters refer to like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0045] In this document, terms such as "upper", "lower", "front", "rear", "left", and "right" are only used to represent the relative positional relationship between relevant parts, rather than defining the absolute positions of these relevant parts.

[0046] In this document, terms such as "first" and "second" are only used to distinguish between each other, rather than indicating importance, order, or the prerequisite for each other's existence, etc.

[0047] In this document, terms such as "equal" and "same" are not strict mathematical and / or geometric limitations, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use, etc.

[0048] The present disclosure provides a cleaning device, which can be a floor washer, a cleaning machine, or other devices for cleaning floors, sofas, carpets, etc. The cleaning device includes a body and a floor brush assembly. For example, the cleaning device of the present disclosure can be a floor washer. When a user uses the floor washer for cleaning work, the user can move the floor washer on the ground by pushing the body of the floor washer, and use the floor brush assembly to clean the ground.

[0049] The floor brush assembly includes: a floor brush housing, a roller brush cover, a roller brush, and a clean water tank. Among them, the floor brush housing is used to carry various components of the floor brush assembly. The roller brush cover is configured to be detachably connected to the floor brush housing according to a preset disassembly and assembly path, and is configured to enclose a roller brush cavity with the floor brush housing. The roller brush is located in the roller brush cavity and is configured to be rotatably connected to the floor brush housing. The roller brush cavity enclosed by the roller brush cover and the floor brush housing can have a shape adapted to the roller brush. The roller brush extends out from the lower end opening of the roller brush cavity to contact the working surface. The roller brush cavity can provide protection for the roller brush and at the same time prevent the roller brush from throwing out dirt when rotating.

[0050] The clean water tank is detachably connected to the floor brush housing. The clean water tank has a liquid storage cavity, and the liquid storage cavity can be used to store liquids for cleaning, such as clean water and cleaning liquid. The liquid storage cavity is configured to extend from a position corresponding to the floor brush housing to a position on the disassembly and assembly path of the roller brush cover. When the disassembly and assembly path of the roller brush cover is in the vertical direction, the liquid storage cavity can extend directly above the roller brush cover; when the disassembly and assembly path of the roller brush cover has a certain angle with the vertical direction, the liquid storage cavity can extend obliquely above the roller brush cover. When the clean water tank is installed on the floor brush housing, the liquid storage cavity will block the disassembly and assembly path of the roller brush cover, and at this time, the roller brush cover cannot be disassembled or assembled; only when the clean water tank is first removed from the floor brush housing can the roller brush cover be disassembled or assembled.

[0051] By arranging the water tank on the floor brush housing, the weight of the machine body is reduced, making it easier for the user to push the machine body of the cleaning device. In addition, the water tank arranged on the floor brush housing increases the downward pressure of the floor brush assembly, thereby improving the cleaning effect of the roller brush on the working surface. The liquid storage cavity of the water tank of the present disclosure extends to a position on the disassembly and assembly path of the roller brush cover, realizing that the water tank can be integrated with the roller brush cover on the floor brush assembly at the same time, and the capacity of the outwardly extending liquid storage cavity is also increased. The amount of water stored in the water tank is sufficient to complete a full-house cleaning, and the user does not need to replenish water repeatedly, improving the user experience.

[0052] The following describes the specific embodiments of the present disclosure in conjunction with the accompanying drawings. It should be noted that the present disclosure also provides a cleaning system. In order to keep the text concise, the cleaning base station and the cleaning device will be introduced together when describing the specific structure and working principle of the cleaning system.

[0053] The present disclosure provides a cleaning system, referring to Figure 1 , the cleaning system includes: a cleaning device 1 and a cleaning base station 2. As Figure 1 shown, the cleaning device 1 includes a machine body 11 and a floor brush assembly 12 connected to the machine body 11. Specifically, the floor brush assembly 12 is connected to the bottom of the machine body 11. The floor brush assembly 12 is used to clean the working surface and is configured to extend a certain length from the bottom of the machine body 11 to the working surface. That is to say, when the cleaning device 1 is working, the floor brush assembly 12 is in contact with the working surface, and the bottom of the machine body 11 is at a certain height from the working surface.

[0054] In an embodiment of the present disclosure, the cleaning device 1 can be a handheld cleaning device. When it is working, the user can hold the handheld part 10 above the machine body 11 to push the cleaning device 1 to move on the working surface, or the user only needs to provide an external force to control the moving direction of the cleaning device 1, and the cleaning device 1 has a self-propelled mechanism and can walk automatically. At the same time, the cleaning components arranged on the floor brush assembly 12 can wipe the stains on the working surface, thereby cleaning the working surface.

[0055] The cleaning device 1 further includes a sewage tank 13 and a water tank 14. Among them, the water tank 14 can provide liquid for cleaning the working surface for the floor brush assembly 12. Specifically, the floor brush assembly 12 may further include a liquid spraying mechanism, which can spray the clean water or cleaning liquid in the water tank 14 onto the cleaning part or directly onto the working surface to be cleaned, thereby ensuring the cleaning effect. The sewage tank 13 can be used to store the dirt after cleaning. Specifically, the floor brush assembly 12 may further include a sewage suction port. While cleaning with the floor brush assembly 12, the dirt after cleaning can be sucked into the sewage tank 13 through the sewage suction port for storage to facilitate subsequent centralized treatment.

[0056] SeeFigures 1 to 3 , the cleaning base station 2 includes a base station body and a water inlet valve assembly 23. The base station body is configured to place the cleaning device 1. Specifically, the cleaning base station 2 can be used as a storage carrier before / after the cleaning device 1 works. The cleaning base station 2 at least includes functions such as charging, sewage discharge, and water replenishment for the cleaning device 1. For example, after the user uses the cleaning device 1 to complete the cleaning work, the cleaning device 1 can be placed on the cleaning base station 2 to dock with the cleaning base station 2, and the cleaning base station 2 can perform subsequent work such as charging, sewage discharge, and water replenishment on the cleaning device 1, reducing the workload of the user's daily cleaning.

[0057] As Figure 1 shown, the base station body includes a base 21 and a tray 22. Among them, the base 21 is configured to extend in the height direction; the tray 22 is configured to extend horizontally to one side of the base 21 and is configured to support the floor brush assembly 12 of the cleaning device 1. In the present disclosure, the side of the base 21 provided with the tray 22 is denoted as the front side, and the side opposite thereto is denoted as the rear side. The cleaning device 1 can be placed on the cleaning base station 2, the floor brush assembly 12 can be supported on the tray 22, the rear side of the fuselage 11 can be docked with the base 21, and the base 21 and the tray 22 can be respectively docked with different positions of the cleaning device 1 to perform maintenance work.

[0058] In an embodiment of the present disclosure, referring to Figure 2 , a sewage discharge groove assembly 211 can be provided on the base 21. The sewage discharge groove assembly 211 can be used to dock with the sewage tank 13, so that after the cleaning device 1 completes the cleaning work, the dirt collected during the cleaning process can be discharged through the sewage discharge groove assembly 211. The sewage tank 13 is provided on the fuselage 11. Specifically, the sewage tank 13 can be provided at the rear side of the fuselage 11. When the cleaning device 1 is docked with the cleaning base station 2, the sewage discharge groove assembly 211 is located below the sewage tank 13 and is communicated with the inner cavity of the sewage tank 13. The dirt in the sewage tank 13 can be discharged to the sewage discharge groove assembly 211 under the action of gravity, and the sewage discharge groove assembly 211 can perform subsequent discharge treatment on the dirt.

[0059] Referring to Figure 2 and Figure 3, the water inlet valve assembly 23 includes a water valve unit provided on the base body of the base station and used for docking with the cleaning device 1. The water valve unit may be provided with only a single water valve or may include multiple water valves. In a specific embodiment of the present disclosure, the water valve unit includes a first water valve 231 and a second water valve 232. In an embodiment of the present disclosure, the first water valve 231 and the second water valve 232 are provided on the tray 22, and the first water valve 231 is configured to be adjacent to the second water valve 232. A small amount of liquid is likely to leak from the first water valve 231 and the second water valve 232 during docking, and a small amount of liquid is likely to remain when the cleaning device 1 is separated from the cleaning base station 2. These liquids will flow downward along the first water valve 231 and the second water valve 232 under the action of gravity. If the first water valve 231 and the second water valve 232 are provided on the base 21, the above-mentioned liquids will drip onto other components at a lower position, which may have an adverse effect on the components at a lower position. In the present disclosure, both the first water valve 231 and the second water valve 232 are provided on the tray 22, so that the water at the water valve can be received by the tray 22 and will not affect other components. The first water valve 231 is configured to communicate with the sewage tank 13 of the cleaning device 1, and the second water valve 232 is configured to communicate with the fresh water tank 14 of the cleaning device 1. In an embodiment of the present disclosure, a first liquid supply pipeline communicating with the first water valve 231 and a second liquid supply pipeline communicating with the second water valve 232 may be provided in the tray 22. The cleaning base station 2 includes a control unit, and the control unit is configured to control the first water valve 231 to flush and / or replenish water to the sewage tank 13 through the first liquid supply pipeline, and is configured to control the second water valve 232 to replenish water to the fresh water tank 14 through the second liquid supply pipeline. In this way, the cleaning base station 2 can realize the functions of flushing and / or replenishing water to the sewage tank 13 and replenishing water to the fresh water tank 14. The user does not need to manually remove the sewage tank 13 for cleaning, nor does the user need to manually remove the fresh water tank 14 for replenishing water, making the cleaning work easier, more convenient, and not dirty hands, improving the user experience.

[0060] Further, the operating parameters of the first water valve 231 and the second water valve 232 are different. Accordingly, the flow rates of the first liquid supply pipeline and the second liquid supply pipeline are different. It can be understood that the second water valve 232 can achieve the function of replenishing water to the clean water tank 14 with only a relatively small flow rate; while the first water valve 231 should adopt a relatively large flow rate to ensure the force when flushing the sewage tank 13. In a specific embodiment of the present disclosure, the control unit is configured to control the flow rate of the first liquid supply pipeline to be 10 L / min to 15 L / min; and / or control the flow rate of the second liquid supply pipeline to be 1.5 L / min to 2.5 L / min. Preferably, the flow rate of the second liquid supply pipeline is 1.7 L / min to 2.3 L / min. Pumps may be respectively provided at the upstream positions of the first liquid supply pipeline and the second liquid supply pipeline, and the control unit can respectively adjust the water flow rates of the first liquid supply pipeline and the second liquid supply pipeline by respectively controlling parameters such as the duty cycle of the two pumps. This ensures the flushing effect of the first water valve 231 on the sewage tank 13 and ensures that the clean water tank 14 can be replenished with water within a reasonable time range.

[0061] In an embodiment of the present disclosure, a third liquid supply pipeline communicating with the sewage tank 13 and a fourth liquid supply pipeline communicating with the clean water tank 14 are provided on the floor brush assembly 12. Refer to Figure 15 and Figure 16 , the third liquid supply pipeline and the fourth liquid supply pipeline are configured to form a first docking portion 151 and a second docking portion 152 for respectively docking with the first water valve 231 and the second water valve 232 at the bottom of the floor brush assembly 12.

[0062] Specifically, the first docking portion 151 may include a first valve core. The first valve core may be arranged at the opening position of the third liquid supply pipeline through a first elastic device. The first elastic device keeps the first valve core in a closed state by elastic force, so that the third liquid supply pipeline remains in a closed state, and the liquid in the sewage tank 13 will not leak from the first docking portion 151. When the first water valve 231 docks with the first docking portion 151, the first ejector rod provided on the first water valve 231 can push the first valve core, so that the first valve core moves to an open state, and the third liquid supply pipeline is communicated with the first water valve 231. The cleaning base station 2 can be sequentially communicated with the sewage tank 13 through the first liquid supply pipeline, the first water valve 231, the first docking portion 151, and the third liquid supply pipeline, so as to flush the sewage tank 13.

[0063] Similarly, the second docking portion 152 may include a second valve core. The second valve core may be disposed at the opening position of the fourth liquid supply pipeline through a second elastic device. The second elastic device keeps the second valve core in a closed state by elastic force, so that the fourth liquid supply pipeline remains in a closed state, and the liquid in the water tank 14 will not leak out from the second docking portion 152. When the second water valve 232 is docked with the second docking portion 152, the second ejector rod provided on the second water valve 232 can push the second valve core, so that the second valve core moves to an open state, and the fourth liquid supply pipeline is communicated with the second water valve 232. The cleaning base station 2 can be sequentially communicated with the water tank 14 through the second liquid supply pipeline, the second water valve 232, the second docking portion 152, and the fourth liquid supply pipeline, so as to replenish water to the water tank 14.

[0064] As described above, the first water valve 231 of the present disclosure is configured to be adjacent to the second water valve 232. Therefore, the first docking portion 151 and the second docking portion 152 may also be arranged adjacent to each other. Refer to Figure 16 , a notch 15 may be formed at the bottom of the floor brush assembly 12. The first docking portion 151 and the second docking portion 152 may be arranged adjacent to each other inside the notch 15. It can be understood that if the notch 15 is not provided, the first docking portion 151 and the second docking portion 152 will protrude from the bottom surface of the floor brush assembly 12. During the cleaning process of the floor brush assembly 12, the first docking portion 151 and the second docking portion 152 are likely to interfere with the working surface. On the one hand, the first docking portion 151 and the second docking portion 152 are easily damaged by collision. On the other hand, the walking smoothness of the cleaning device 1 is reduced, and the user experience is poor. By providing the notch 15 in the present disclosure, the first docking portion 151 and the second docking portion 152 do not protrude from the bottom surface of the floor brush assembly 12, thereby preventing the first docking portion 151 and the second docking portion 152 from being damaged by collision, improving the walking smoothness of the cleaning device 1, and enhancing the user experience.

[0065] In the present disclosure, by arranging both the first water valve 231 and the second water valve 232 on the tray 22, both water valves are located at the lowest position of the cleaning base station 2, and the cleaning device 1 can be stably docked under its own gravity. In addition, the water at the water valve can be received by the tray 22 without affecting other components. In addition, the first water valve 231 and the second water valve 232 are adjacent to each other, thereby improving the integration of the upper water valve assembly 23. Only one notch 15 for docking with the upper water valve assembly 23 may be formed on the floor brush assembly 12, without separately opening holes for docking the first water valve 231 and the second water valve 232.

[0066] In an embodiment of the present disclosure, refer to Figure 2 and Figure 4, the water inlet valve assembly 23 includes a mounting base 233, and the water valve unit is configured to be located on the mounting base 233. In this embodiment, the first water valve 231 and the second water valve 232 are located on the mounting base 233. The top of the mounting base 33 is configured to protrude above the top end surface of the tray 22. Specifically, an opening can be provided on the top end surface of the tray 22, and the top of the mounting base 233 can extend out of the opening to be higher than the top end surface of the tray 22. As described above, a first liquid supply pipeline and a second liquid supply pipeline are provided in the tray 22. In order to enable the first water valve 231 and the second water valve 232 to be smoothly connected to the first liquid supply pipeline and the second liquid supply pipeline, the mounting base 233 can extend out of the top end surface of the tray 22 from the inner cavity of the tray 22.

[0067] By providing the mounting base 233 integrated with the first water valve 231 and the second water valve 232, the integration degree of the water inlet valve assembly 23 is improved, making the water inlet valve assembly 23 more integral. The mounting base 233 extends out of the opening on the tray 22 to protrude above the top end surface of the tray 22. When the cleaning device 1 is docked with the cleaning base station 2, the mounting base 233 can extend into the notch 15 on the bottom surface of the floor brush assembly 12 for docking. The mounting base 233 can have a shape adapted to the notch 15, such as a shape similar to an ellipse or a shape similar to a rounded rectangle. The present disclosure does not limit this.

[0068] Furthermore, as Figure 4 shown, there are two adjacent mounting holes 230 on the mounting base 233, and the first water valve 231 and the second water valve 232 are respectively configured to be located in the corresponding mounting holes 230. The two mounting holes 230 can have exactly the same shape and size, and the first water valve 231 and the second water valve 232 can also have exactly the same shape and size, so that the appearance of the water inlet valve assembly 23 is beautiful and has strong integrity. During docking, the first docking portion 151 and the second docking portion 152 in the notch 15 of the floor brush assembly 12 can respectively extend into the two mounting holes 230 to respectively dock with the first water valve 231 and the second water valve 232, so as to connect the water flow path between the cleaning base station 2 and the cleaning device 1.

[0069] In an embodiment of the present disclosure, referring to Figure 15 , a traveling mechanism is provided on the bottom surface of the floor brush assembly 12. The traveling mechanism can include two traveling wheels 123 spaced apart on both sides of the bottom surface of the floor brush assembly 12, and a driving wheel 124 provided between the two traveling wheels 123. The driving wheel 124 can rotate under the drive of the motor to provide traveling power for the floor brush assembly 12, and the two traveling wheels 123 can play an auxiliary role during the traveling of the floor brush assembly 12, so as to facilitate the cleaning device 1 to maintain balance.

[0070] The walking wheels 123 and the driving wheels 124 both protrude partially from the bottom surface of the floor brush assembly 12. Therefore, accommodation spaces need to be provided on the tray 22 for the walking wheels 123 and the driving wheels 124 respectively. Specifically, referring to Figure 2 and Figure 3 , walking wheel grooves 221 are provided at both ends of the tray 22, and a driving wheel groove 222 is provided between the two walking wheel grooves 221. When the cleaning device 1 is docked with the cleaning base station 2, the walking wheels 123 are located in the walking wheel grooves 221, and the driving wheels 124 are located in the driving wheel grooves 124, so that the cleaning device 1 can be stably supported on the cleaning base station 2.

[0071] In an embodiment of the present disclosure, as Figure 3 shown, an X-axis and a Y-axis perpendicular to each other in the horizontal plane are defined. Among them, the front-back direction of the base 21 is defined as the direction of the Y-axis line, and the first water valve 231 and the second water valve 232 are arranged along the X-axis direction. As Figure 2 shown, the water supply valve assembly 23 is configured to be located in the area between the central axis of the tray 22 and the outer edge line of one of the walking wheel grooves 221; among them, the central axis of the tray 22 and the outer edge line of the walking wheel groove 221 extend along the Y-axis line direction.

[0072] Figure 2 The two dashed lines in Figure 2 respectively represent the central axis of the tray 22 and the outer edge line of one of the walking wheel grooves 221. The water supply valve assembly 23 can be arranged at a position between the two dashed lines, so that the layout on the tray 22 is reasonable. It can be understood that Figure 2 only shows the layout scenario where the water supply valve assembly 23 is located between the outer edge line of the right walking wheel groove 221 and the central axis of the tray 22. In fact, the water supply valve assembly 23 can also be located at a position between the outer edge line of the left walking wheel groove 221 and the central axis of the tray 22.

[0073] In an embodiment of the present disclosure, as Figure 2 shown, a charging part protruding from the top end face of the tray 22 is provided on the tray 22. The charging part is configured to be used for docking with the cleaning device 1 to charge the cleaning device 1. Referring to Figure 15 , a charging port 125 can be provided on the bottom surface of the floor brush assembly 12. When the cleaning device 1 is docked with the cleaning base station 2, the protruding charging part on the tray 22 can extend into the charging port 125, and a circuit connection can be formed between the two, so as to realize charging the cleaning device 1 by the cleaning base station 2.

[0074] Furthermore, two charging ports 125 can be provided, and the two charging ports 125 can be symmetrically arranged on opposite sides of the central axis of the floor brush assembly 12. Correspondingly, two charging parts can also be provided, and the two charging parts can be symmetrically arranged on opposite sides of the central axis of the tray 22.

[0075] As shown Figure 2 in the figure, a charging contact piece 224 for power supply is provided on the charging part, and the lowest point of the charging contact piece 224 is configured to be higher than the first water valve 231 and the second water valve 232. It should be noted that the charging contact piece 224 is a structure for charging the cleaning device 1, which is usually made of metal material. The charging contact piece 224 should not contact the liquid, otherwise leakage or short - circuit accidents may occur, posing a safety hazard, and the circuit of the cleaning base station 2 may also be affected accordingly, resulting in a failure of the cleaning base station 2. In the present disclosure, the lowest point of the charging contact piece 224 is set at a height higher than the first water valve 231 and the second water valve 232, thereby preventing the water flow at the first water valve 231 and the second water valve 232 from flowing to the charging contact piece 224, effectively preventing leakage or short - circuit accidents, and improving the safety of the cleaning base station 2.

[0076] In one embodiment of the present disclosure, referring to Figures 3 to 12 , the cleaning base station of the present disclosure further includes a locking assembly, and the locking assembly is located in the X - axis direction and / or Y - axis direction of the water inlet valve assembly 23. As Figure 3 shown in the figure, since the water inlet valve assembly 23 has a certain length and width, the water inlet valve assembly 23 can respectively extend to form an X region and a Y region on the tray 22 in the X - axis and Y - axis directions, and the locking assembly is located in the X region and / or Y region. It should be noted that Figure 3 the X region and the Y region shown are located in the horizontal plane where the tray 22 is located. In other application scenarios, the X region and the Y region can also be located in other planes, and the present disclosure does not limit this. For example: the Y region can extend to the base 21, and the locking assembly can be arranged on the base 21.

[0077] The locking assembly is configured to move between a locking position and an unlocking position. Specifically, Figures 5 to 8 shows the structure of the locking assembly in the locking position: when in the locking position, the locking assembly is configured to lock the cleaning device 1 to the base station body; Figures 9 to 12 shows the structure of the locking assembly in the unlocking position: when in the unlocking position, the locking assembly is configured to unlock the cleaning device 1 from the base station body.

[0078] It should be noted that, in an embodiment of the present disclosure, the locking assembly may be provided on the cleaning base station 2 or on the cleaning device 1. When the locking assembly is provided on the cleaning base station 2, the locking assembly can move relative to the base body between a locking position and an unlocking position; when in the locking position, the locking assembly can cooperate with the cleaning device 1 to lock the cleaning device 1 to the base body; when in the unlocking position, the locking assembly can be separated from the cleaning device 1 to unlock the cleaning device 1 from the base body. When the locking assembly is provided on the cleaning device 1, the locking assembly can move relative to the cleaning device 1 between a locking position and an unlocking position; when in the locking position, the locking assembly can cooperate with the cleaning base station 2 to lock the cleaning device 1 to the base body; when in the unlocking position, the locking assembly can be separated from the cleaning base station 2 to unlock the cleaning device 1 from the base body. The following will be described by taking the locking assembly provided on the cleaning base station 2 as an example.

[0079] The present disclosure improves the docking stability between the cleaning device 1 and the cleaning base station 2 by providing a locking assembly. Specifically, the locking assembly can firmly lock the cleaning device 1 to the base body, and the water pressure when the cleaning base station 2 supplies water to the cleaning device 1 will not lift the cleaning device 1, thereby preventing water leakage. In addition, the instability of the docking between the cleaning device 1 and the cleaning base station 2 is mainly caused by the water pressure impact during the operation of the water supply valve assembly 23. By arranging the locking assembly in the X-axis and / or Y-axis direction of the water supply valve assembly 23, the locking position of the cleaning device 1 is directly related to the water supply valve assembly 23, which is beneficial to balancing the water pressure impact during water supply, can most effectively ensure stable docking at the water supply valve assembly 23, and further improves the overall docking stability.

[0080] In an embodiment of the present disclosure, there are at least two locking assemblies, and the at least two locking assemblies are arranged in the X-axis direction and are located on both sides of the water supply valve assembly 23; and / or, the at least two locking assemblies are arranged in the Y-axis direction and are located on both sides of the water supply valve assembly 23. Refer to Figure 3 the view direction. When there are two locking assemblies, the two locking assemblies can be respectively arranged on the left and right sides or the upper and lower sides of the water supply valve assembly 23. The distances between the two locking assemblies and the water supply valve assembly 23 can be equal. The two locking assemblies can lock the cleaning device 1 to the cleaning base station 2 together, thereby balancing the water pressure impact during water supply, avoiding uneven unilateral force on the cleaning device 1, and improving the docking stability of the cleaning device 1.

[0081] When there are more than two locking components, the multiple locking components may not be evenly distributed on both sides in the X-axis direction and / or the Y-axis direction of the water inlet valve assembly 23. In this case, the force on each locking component can be calculated separately, and the multiple locking components can be reasonably arranged, so that the locking components on both sides of the water inlet valve assembly 23 are evenly stressed, thereby balancing the water pressure impact during water supply and improving the docking stability of the cleaning device 1.

[0082] In another embodiment of the present disclosure, the locking component is provided as one, and one locking component is configured to be located adjacent to the water inlet valve assembly 23, so as to facilitate the locking component to balance the water pressure impact at the water inlet valve assembly 23. When the locking component is located adjacent to the water inlet valve assembly 23, there is no need to provide multiple locking components, and only one locking component can stably lock the cleaning device 1 on the cleaning base station 2.

[0083] In a preferred embodiment of the present disclosure, one locking component is configured to be provided between the first water valve 231 and the second water valve 232, whereby the water pressure impact of the two water valves can be balanced by only one locking component. Whether the first water valve 231 flushes the sewage tank 13, the second water valve 232 replenishes water to the clean water tank 14, or the two water valves work together, the locking component provided between the first water valve 231 and the second water valve 232 can balance the water pressure impact and improve the docking stability of the cleaning device 1.

[0084] In another embodiment of the present disclosure, the locking component is configured to be provided on the mounting base 233. As described above, the water inlet valve assembly 23 is provided on the tray 22 and is used to cooperate with the floor brush assembly 12 of the cleaning device 1. The locking component provided on the mounting base 233 can move between a locking position and an unlocking position relative to the mounting base 233. Specifically, when moving to the locking position, the locking component can cooperate with the floor brush assembly 12 to lock the floor brush assembly 12 on the tray 22; when moving to the unlocking position, the locking component can disengage from the floor brush assembly 12.

[0085] It should be noted that setting the locking component on the mounting base 233 is the most preferred embodiment of the present disclosure. The mounting base 233 is a part of the water inlet valve assembly 23. Directly installing the locking component on the water inlet valve assembly 23 can achieve the best effect of balancing the water pressure impact and the best locking effect. The water pressure when the cleaning base station 2 supplies water to the cleaning device 1 will not lift the floor brush assembly 12, and the occurrence of water leakage is maximally prevented.

[0086] In an embodiment of the present disclosure, refer to Figures 4 to 13The locking assembly includes a driving mechanism and a locking mechanism 241. The locking mechanism 241 is configured to be located in the X-axis direction and / or the Y-axis direction of the water supply valve assembly 23 and is movable relative to the mounting seat 233, and is configured to move between a locking position and an unlocking position under the action of the driving mechanism. Figure 13 As shown, the locking mechanism 241 has a locking end for cooperating with the floor brush assembly 12, and also has a driving end arranged opposite to the locking end, and the driving end can be used for transmission connection with the driving mechanism. The locking end can be constructed as a hook 2410, and when it is in the locking position, the hook 2410 can lock the floor brush assembly 12 on the tray 22; when it is in the unlocking position, the hook 2410 can be separated from the floor brush assembly 12.

[0087] Specifically, refer to Figure 4 , Figure 8 and Figure 12 The mounting seat 233 is provided with an opening 2331. Specifically, the opening 2331 can be provided on the side wall of the mounting seat 233 located in the X-axis direction, that is, the opening 2331 is located on the side wall of the mounting seat 233 extending along the X-axis direction. Figure 8 As shown, when in the locked position, the locking end of the locking mechanism 241 is configured to at least partially extend from the opening 2331 to lock with the cleaning device 1; Figure 12 As shown, when in the unlocked position, the locking end of the locking mechanism 241 is configured to be retracted from the opening 2331 into the inner cavity of the mounting seat 233 to detach from the cleaning device 1 .

[0088] When the hook 2410 of the locking mechanism 241 moves to the locked position, it can extend outward from the side wall of the mounting seat 233 in the X-axis direction to cooperate with the floor brush assembly 12. Figure 16 As shown, a locking groove 153 is provided on the side wall of the notch 15, and the hook 2410 at the locking position can extend into the locking groove 153, thereby locking the floor brush assembly 12 on the tray 22. Figure 12 As shown, when the locking mechanism 241 is in the unlocked position, the hook 2410 can disengage from the engaging groove 153 and retract into the mounting base 33. At this time, the locking mechanism 241 will not interfere with the floor brush assembly 12, so that the floor brush assembly 12 can be easily separated from the water supply valve assembly 23, and the user can easily remove the cleaning device 1 from the cleaning base station 2.

[0089] In one embodiment of the present disclosure, Figure 13As shown, the latch mechanism 241 can be installed on a component within the inner cavity of the tray 22 and extend into the interior of the mounting base 233, such that when the latch mechanism 241 is in the locked position, at least a part of its locking end protrudes from the opening 2331. In a specific embodiment, the latch mechanism 241 can also be directly installed on the mounting base 233. The latch mechanism 241 includes a rotating shaft 2411, and the rotating shaft 2411 can be disposed at the middle position of the latch mechanism 241, specifically, it can be disposed at a position slightly above the middle. Referring to Figure 13 the view direction, the locking end hook 2410 of the latch mechanism 241 is located above the rotating shaft 2411, and the driving end of the latch mechanism 241 is located below the rotating shaft 2411. The latch mechanism 241 can be hinged to the mounting base 233 through the rotating shaft 2411, or hinged to other components within the inner cavity of the tray 22.

[0090] Referring to Figure 7 and Figure 11 , the driving mechanism includes a fixed part and a movable part that cooperates with the fixed part. The movable part is in transmission connection with the driving end of the latch mechanism 241 and is configured to drive the latch mechanism 241 to move between the locked position and the unlocked position around its rotating shaft 2411. The movable part can be a rod-shaped movable shaft, and a flange 2421 can be provided at one end of the movable part close to the latch mechanism 241. A waist-shaped hole 2412 is provided on the driving end of the latch mechanism 241. During the movement of the movable part relative to the fixed part, the flange 2421 at its end position can slide along the waist-shaped hole 2412 and simultaneously drive the latch mechanism 241 to rotate around the rotating shaft 2411 and move between the locked position and the unlocked position.

[0091] Referring to Figure 7 the view direction, when the movable part moves away from the direction where the latch mechanism 241 is located, that is, moves to the left, the flange 2421 can slide downward along the waist-shaped hole 2412. The driving end of the latch mechanism 241 moves to the left, so that the latch mechanism 241 rotates clockwise around the rotating shaft 2411, and further makes the hook 2410 move outside the opening 2331 of the mounting base 233, thereby making the latch mechanism 241 move to the locked position.

[0092] Referring to Figure 11 the view direction, when the movable part moves towards the direction where the latch mechanism 241 is located, that is, moves to the right, the flange 2421 can slide upward along the waist-shaped hole 2412. The driving end of the latch mechanism 241 moves to the right, so that the latch mechanism 241 rotates counterclockwise around the rotating shaft 2411, and further makes the hook 2410 move into the opening 2331 of the mounting base 233, thereby making the latch mechanism 241 move to the unlocked position.

[0093] In an embodiment of the present disclosure, as Figure 14As shown, when in the locked position, the line connecting the acting position of the locking end on the cleaning device 1 and the rotation center of the rotating shaft 2411 is configured to be perpendicular to the movement axis of the movable part. When the catch 2410 is engaged in the engagement groove 153, the contact position between the two is the Figure 14 force-bearing position marked in the figure, and the line connecting the force-bearing position and the rotation center of the rotating shaft 2411 is as Figure 14 shown by the dashed line in the figure. This line is perpendicular to the movement axis of the movable part, so that when the locking mechanism 241 locks the floor brush assembly 12, basically all the locking force can be borne by the locking mechanism 241, and the driving mechanism is basically not stressed. Moreover, such a structural design can also increase the upper limit of the locking force of the catch 2410.

[0094] In an embodiment of the present disclosure, referring to Figure 7 and Figure 11 , the fixed part is the electromagnet 243, and the movable part is the iron core 242. Specifically, an inner cavity is provided in the electromagnet 243, and the iron core 242 is located in the inner cavity of the electromagnet 243. The electromagnet 243 is configured to drive the iron core 242 to drive the locking mechanism 241 to move from the unlocked position to the locked position when powered on. Referring to Figure 7 the view direction, in the powered-on state, the iron core 242 located in the inner cavity of the electromagnet 243 can be subjected to a leftward force under the action of electromagnetic induction. The iron core 242 moves leftward and drives the locking mechanism 241 to rotate, so that the locking mechanism 241 moves from the Figure 11 locking position shown in the figure to the Figure 7 locked position shown in the figure. In this embodiment, electromagnetic force is used to drive the locking mechanism 241, so that various conventional electric control methods can be used to control the locking. For example, the circuit can be controlled by means of buttons, remote control, etc. When powered on, the locking mechanism 241 can be driven to move to the locked position.

[0095] Furthermore, continuing to refer to Figure 7 and Figure 11 , the driving mechanism further includes a first elastic member 244 pre-pressed between the iron core 242 and the electromagnet 243. The first elastic member 244 can be a spring. When the electromagnet 243 is powered on, the iron core 242 moves towards the electromagnet 243 under the action of electromagnetic force, and the distance between the iron core 242 and the electromagnet 243 gradually decreases, compressing the first elastic member 244; when the electromagnet 243 is powered off, the iron core 242 is no longer subjected to electromagnetic force, and the iron core 242 is configured to drive the locking mechanism 241 to move from the locked position to the unlocked position under the elastic force of the first elastic member 244.

[0096] In the prior art, in the case of a power outage, the cleaning device 1 may be locked on the cleaning base station 2 and cannot be removed. This is because the prior art usually uses an electro-mechanical locking mechanism to lock the cleaning device 1 on the cleaning base station 2. The locking and unlocking of such a locking mechanism both require power drive and do not have the characteristic that the acting force disappears after a power outage like the electromagnet 243. In the case of an accidental power outage, the locking mechanism cannot move and will continue to remain in the locked position, resulting in the cleaning device 1 being locked on the cleaning base station 2 and unable to be removed.

[0097] In this embodiment, the electromagnet 243 is used to drive the iron core 24 to drive the locking mechanism 241 to move between the locked position and the unlocked position. In the case of an accidental power outage, the electromagnet 243 is powered off, and the electromagnetic acting force received by the iron core 24 thus disappears; at this time, the elastic force accumulated by the compression of the first elastic member 244 is released, so that the iron core 24 can move smoothly and reset under the action of the elastic force to drive the locking mechanism 241 to unlock. This disclosure realizes the power-off automatic reset function and avoids the problem that the cleaning device 1 is locked on the cleaning base station 2 and cannot be removed due to a power outage.

[0098] It should be noted that the locking mechanism 241 does not need to continuously lock the floor brush assembly 12, but can lock the floor brush assembly 12 only when the water supply valve assembly 23 is performing the water supply operation. If the locking mechanism 241 continuously locks the floor brush assembly 12, it will cause the electromagnet 243 to be energized for a long time, which will cause the electromagnet 243 to overheat. In order to prevent the electromagnet 243 from overheating, the single energization time should not be too long, and it can be locked only when the water supply valve assembly 23 is working. At other times when the water supply valve assembly 23 is not working, the cleaning device 1 is basically not subjected to too much external force, and the cleaning device 1 can be stably supported on the cleaning base station 2 by its own weight without the need for locking.

[0099] In an embodiment of the present disclosure, with continued reference to Figure 7 and Figure 11 , the cleaning base station 2 further includes a trigger member 245, and the trigger member 245 can be a detection mechanism such as a micro switch. The trigger member 245 is configured to be triggered when the iron core 242 or the locking mechanism 241 moves to the locked position and / or the unlocked position. In a specific embodiment of the present disclosure, the trigger member 245 can be disposed at a position of the iron core 242 away from the locking mechanism 241. As Figure 7 shown, when the locking mechanism 241 is in the locked position, the trigger member 245 can come into contact with the iron core 242 and thus be triggered by the iron core 242; as Figure 11As shown, when the latch mechanism 241 is in the unlocked position, the trigger member 245 can be separated from the iron core 242. A heat-insulating silica gel 246 can be provided at one end of the iron core 242 close to the trigger member 245. The iron core 242 generates heat during operation, and the heat-insulating silica gel 246 can isolate the heat of the iron core 242 from the trigger member 245, thereby prolonging the service life of the trigger member 245.

[0100] The trigger member 245 can also have other setting forms. For example, it can be triggered not by the iron core 242, but the trigger member 245 can be set at a position that can be directly triggered by the latch mechanism 241; the trigger member 245 can also be configured to be triggered when the latch mechanism 241 is in the unlocked position. The present disclosure does not limit the specific triggering method of the trigger member 245.

[0101] The cleaning base station 2 further includes a control unit configured to control the water supply based on the electrical signal of the trigger member 245. When water supply is required, the control unit needs to control the electromagnet 243 to be energized, so that the latch mechanism 241 moves to the locked position. At this time, the trigger member 245 is triggered; the triggering of the trigger member 245 indicates that the cleaning device 1 has been firmly locked on the cleaning base station 2. At this time, the water supply work can be started, and the control unit can control the water pump inside the cleaning base station 2 to supply water. By providing the trigger member 245, it is ensured that the water supply starts after locking. Otherwise, the water supply may start before locking, and the water pressure of the water supply will impact the cleaning device 1, resulting in instability of the cleaning device 1. Water leakage may occur in the unstable state, and it will also make it difficult for the hook 2410 to align with the engaging groove 153, making the locking difficult.

[0102] In addition, when the trigger member 245 is triggered, it means that the latch mechanism 241 is in the locked position. The control unit can know the current state of the latch mechanism based on the electrical signal, and thus can issue other control information. The control information can be information to remind the user of the current state. For example, it can be displayed on the display screen, or can be reminded in the form of a reminder light, etc.

[0103] In another embodiment of the present disclosure, the locking mechanism 241 may not be driven by electricity, but may be movably arranged on the mounting base 233 by a fully mechanical connection. The fully mechanical connection method can also avoid the situation where the cleaning device 1 is locked on the cleaning base station 2 and cannot be removed for use due to an unexpected power outage. Specifically, the locking mechanism 241 is constructed to be pre-pressed on the mounting base 233 by a second elastic member, and is configured to remain in a locked position under the elastic force of the second elastic member. The locking mechanism 241 can always remain in the locked position under the action of elastic force without being subjected to external force. Regardless of whether there is a cleaning device 1 on the cleaning base station 2, the hook 2410 on the locking mechanism 241 can always be exposed to the outside of the mounting base 233 as long as it is not subjected to external force.

[0104] When the cleaning device 1 is docked, the locking mechanism 241 is constructed to move to the unlocked position when subjected to the docking force of the cleaning device 1, and to move to the locked position under the action of the second elastic member after docking. When docking, the locking mechanism 241 moves under the action of the docking force of the cleaning device 1, and the hook 2410 retracts into the inner cavity of the mounting seat 233, while the second elastic member is compressed by the locking mechanism 241; when docking is completed, the locking mechanism 241 is no longer subjected to the docking force, and the hook 2410 can be ejected from the opening 2331 of the mounting seat 233 under the action of the elastic force, thereby extending into the engaging groove 153 of the floor brush assembly 12 to lock the floor brush assembly 12 on the tray 22.

[0105] In this embodiment, the driving mechanism is a mechanical button arranged on the side wall or top of the base station body, for example, it can be a button arranged on the top of the base 21, or it can be a kick block arranged on the side wall of the cleaning base station 2. The mechanical button is configured to drive the locking mechanism 241 to move to the unlocked position when subjected to an external force. The mechanical button is connected to the locking mechanism 241 by transmission. When the user drives the mechanical button, the locking mechanism 241 can move from the locked position to the unlocked position. At this time, the user can remove the cleaning device 1 from the cleaning base station 2; after removing the cleaning device 1, the user can stop driving the mechanical button, and the locking mechanism 241 is no longer driven by the mechanical button, so that it can be reset to the locked position under the elastic force of the second elastic member.

[0106] refer to Figures 17 to 23, the clean water tank 14 of the present disclosure is arranged on the floor brush assembly 12. The floor brush assembly 12 includes a floor brush housing 120, a roller brush cover 122, a roller brush 121 and a clean water tank 14, wherein the floor brush housing 120 is used to carry various components of the floor brush assembly 12, and the roller brush cover 122 is constructed to be detachably connected to the floor brush housing 120 according to a preset disassembly and assembly path, and is constructed to form a roller brush cavity with the floor brush housing 120. The roller brush 121 is located in the roller brush cavity, and is constructed to be rotatably connected to the floor brush housing 120. The roller brush cavity surrounded by the roller brush cover 122 and the floor brush housing 120 can have a shape that matches the roller brush 121, and the roller brush 121 extends from the lower end opening of the roller brush cavity to contact the working surface. The roller brush cavity can provide protection for the roller brush 121, and at the same time, it can prevent the dirt from being thrown out when the roller brush 121 rotates.

[0107] During the operation of the cleaning device 1, the roller brush 121 can rotate relative to the working surface, thereby cleaning the working surface. The roller brush 121 partially protrudes from the bottom surface of the floor brush assembly 12, so a storage space for the roller brush 121 needs to be provided on the tray 22. Figure 2 A roller brush groove 223 is provided on the tray 22 . When the cleaning device 1 is docked with the cleaning base station 2 , the roller brush 121 is located in the roller brush groove 223 , so that the cleaning device 1 can be stably supported on the cleaning base station 2 .

[0108] In one embodiment of the present disclosure, in order to realize the disassembly and assembly of the roller brush cover 122, as shown in FIG. Figure 21 As shown, arc-shaped buckles 1222 may be respectively provided on both sides of the roller brush cover 122, and two guide grooves matched with the arc-shaped buckles 1222 may be provided on the floor brush housing 120. The arc-shaped buckle 1222 may be provided on the roller brush cover 122 by an elastic device, and the arc-shaped buckle 1222 is kept in a position extending out of the end of the roller brush cover 122 under the action of the elastic device; and when the arc-shaped buckle 1222 is acted upon by an external force, it overcomes the elastic force and retracts into the roller brush cover 122. In the absence of external force, the arc-shaped buckle 1222 will remain in the guide groove under the elastic force of the elastic device; only when the elastic device is compressed due to external force, the arc-shaped buckle 1222 can retract into the roller brush cover 122, thereby disengaging from the guide groove. In order to facilitate the disassembly and assembly of the roller brush cover 122, as shown in FIG. Figure 21 As shown, a buckle handle 1221 may be provided on the roller brush cover 122 , and the user can drive the arc buckle 1222 to move through the buckle handle 1221 to achieve the disassembly and assembly of the roller brush cover 122 .

[0109] Continue to refer Figure 21Two buckles 1221 are provided on the roller brush cover 122, and the two buckles 1221 are constructed to move in a manner of facing or departing from the roller brush cover 122. The two buckles 1221 compress their respective corresponding elastic devices when subjected to external force. When the roller brush cover 122 needs to be detached from the floor brush housing 120, the user can pinch the two buckles 1221 and apply force in the direction of approaching each other. The two buckles 1221 compress their respective corresponding elastic devices respectively, so that the respective corresponding arc buckles 1222 move to disengage from the guide groove. At this time, the user only needs to lift the buckles 1221 upwards to detach the roller brush cover 122 from the floor brush housing 120. It can be understood that the disassembly and assembly path of the roller brush cover 122 can be in the vertical direction or at a certain angle to the vertical direction.

[0110] refer to Figures 17 to 20 The clean water tank 14 of the present disclosure is detachably connected to the floor brush housing 120, and the clean water tank 14 has a liquid storage chamber 140, which can be used to store clean water, cleaning liquid, and other liquids used for cleaning. Figure 20 As shown, a water inlet is provided on the bottom surface of the clean water tank 14, and a cover 1451 is detachably provided on the water inlet. Specifically, the cover 1451 can be a rotating cover, and the user can manually detach the clean water tank 14 from the floor brush housing 120, and unscrew the cover 1451 from the bottom surface of the clean water tank 14, so that water can be replenished into the liquid storage chamber 140 through the water inlet; after the water replenishment is completed, the user only needs to manually tighten the cover 1451 to seal the water inlet. It should be noted that under normal circumstances, the cleaning base station 2 can automatically replenish water for the clean water tank 14, but when the automatic water replenishment function fails or the user wants to replenish water manually, the manual water replenishment function can be easily realized through the cover 1451 on the clean water tank 14.

[0111] refer to Figure 19 and Figure 20 A first pipe joint 1201 is provided on the floor brush housing 120, and a second pipe joint 145 for docking with the first pipe joint 1201 is provided on the clean water tank 14. When the clean water tank 14 is installed on the floor brush housing 210, the first pipe joint 1201 can be docked with the second pipe joint 145, so that the liquid in the liquid storage chamber 140 can flow into the floor brush assembly 12 through the second pipe joint 145 and the first pipe joint 1201 to realize the liquid supply function; and the liquid in the cleaning base station 2 can flow into the liquid storage chamber 140 through the second liquid supply pipeline, the second water valve 232, the first pipe joint 1201, and the second pipe joint 145, thereby realizing the automatic water replenishment of the clean water tank 14 by the cleaning base station 2.

[0112] The second pipe joint 145 is configured to be located on the cover body 1451, whereby the water injection path is unique, the opening connectors on the water tank 14 are reduced, thereby reducing the structural complexity of the water tank 14 and reducing the water storage corners inside the water tank 14. In addition, in the present disclosure, the water injection port is opened on the bottom surface of the water tank 14, that is, the cover body 1451 and the second pipe joint 145 are also located on the bottom surface of the water tank 14, whereby the upper surface of the water tank 14 is made flat and smooth, maintaining the continuity in appearance.

[0113] The liquid storage cavity 140 is configured to extend from the position corresponding to the floor brush housing 120 to the disassembly and assembly path of the roller brush cover 122. When the disassembly and assembly path of the roller brush cover 122 is in the vertical direction, the liquid storage cavity 140 can extend directly above the roller brush cover 122; when the disassembly and assembly path of the roller brush cover 122 has a certain angle with the vertical direction, the liquid storage cavity 140 can extend diagonally above the roller brush cover 122. When the water tank 14 is installed on the floor brush housing 120, the liquid storage cavity 140 will block the disassembly and assembly path of the roller brush cover 122, and at this time, the roller brush cover 122 cannot be disassembled or assembled; only when the water tank 14 is first removed from the floor brush housing 120 can the roller brush cover 122 be disassembled or assembled.

[0114] In the present disclosure, by arranging the water tank 14 on the floor brush housing 120, the weight of the body 11 is reduced, making it easier for the user to push the body 11 of the cleaning device 1. In addition, the water tank 14 arranged on the floor brush housing 120 increases the downward pressure of the floor brush assembly 12, thereby improving the cleaning effect of the roller brush 121 on the working surface. The liquid storage cavity 140 of the water tank 14 in the present disclosure extends to the position on the disassembly and assembly path of the roller brush cover 122, realizing that the water tank 14 can be integrated with the roller brush cover 122 on the floor brush assembly 12 at the same time, and the capacity of the outwardly extending liquid storage cavity 140 also increases the capacity of the water tank 14. The amount of water stored in the water tank 14 is sufficient to complete a full-house cleaning, and the user does not need to replenish water repeatedly, improving the user experience.

[0115] In an embodiment of the present disclosure, taking the side of the cleaning device 1 facing the user in the state of cleaning the working surface as the rear side, and the side opposite thereto as the front side, the roller brush cover 122 is configured to be arranged on the front side of the floor brush housing 120, and the liquid storage cavity 140 is configured to extend forward to the disassembly and assembly path of the roller brush cover 122. It can be understood that the user usually stands behind the cleaning device 1 and realizes cleaning by pushing and pulling the body 11 back and forth through the hand-held part 10. The roller brush 121 is usually located in front of the floor brush assembly 12, and the roller brush cover 122 is also located in front of the floor brush assembly 12. In order to increase the capacity of the liquid storage cavity 140, the liquid storage cavity 140 in the present disclosure extends forward to the disassembly and assembly path of the roller brush cover 122.

[0116] Specifically, the liquid storage cavity 140 is installed at the top of the floor brush housing 120 and is configured to extend forward above the roller brush cover 122, so that the orthographic projections of the liquid storage cavity 140 and the working surface of the roller brush cover 122 at least partially overlap. In this embodiment, the disassembly and assembly path of the roller brush cover 122 can be vertically upward. The liquid storage cavity 140 extending above the roller brush cover 122 has a larger capacity, thereby reducing the number of times the user returns to the cleaning base station 2 to replenish water.

[0117] Furthermore, in an embodiment of the present disclosure, the top end face of the clean water tank 14 is configured to form at least a part of the top end face of the floor brush assembly 12. The clean water tank 14 installed above the roller brush cover 122 has a space for upward extension. Since the top end face of the clean water tank 14 can serve as at least a part of the top of the floor brush assembly 12, it can be seen that there are no other components blocking above at least a part of the clean water tank 14. Therefore, the clean water tank 14 can be appropriately extended upward, thereby further increasing the capacity of the liquid storage cavity 140.

[0118] Preferably, the roller brush cover 122 is configured to have a top, and the liquid storage cavity 140 is configured to extend to cover the top of the roller brush cover 122. In this case, the liquid storage cavity 140 can cover at least a part of the upper surface of the roller brush cover 122, and the top end face of the clean water tank 14 participates in enclosing most or all of the upper surface of the floor brush assembly 12, so that the projected area of the clean water tank 14 on the working surface is increased as much as possible, and thus the capacity of the liquid storage cavity 140 is increased as much as possible.

[0119] When the height of the clean water tank 14 remains unchanged, in order to maximize the capacity of the liquid storage cavity 140, it is necessary to maximize the projected area of the clean water tank 14 on the working surface. In a specific embodiment of the present disclosure, the liquid storage cavity 140 is configured to cover the top end face of the floor brush housing 120. In this case, the liquid storage cavity 140 can completely cover the upper surface of the roller brush cover 122, and the top end face of the clean water tank 14 encloses the entire upper surface of the floor brush assembly 12, thereby maximizing the capacity of the liquid storage cavity 140.

[0120] In an embodiment of the present disclosure, the roller brush cover 122 further includes a front side wall that extends obliquely downward from the front side of its top. The front side wall of the roller brush cover 122 and the front side wall of the clean water tank 14 are configured to form the front side wall of the floor brush assembly 12. Specifically, the front side wall of the clean water tank 14 and the front side wall of the roller brush cover 122 together form the front side wall of the floor brush assembly 12. As Figure 17 shown, the front side wall of the roller brush cover 122 is located in a more forward position than the front side wall of the clean water tank 14. During the cleaning process, the front end of the floor brush assembly 12 may collide with an obstacle, and the front side wall of the roller brush cover 122 can protect the clean water tank 14 from direct frontal collision.

[0121] In an embodiment of the present disclosure, referring toFigures 18 to 20 An upwardly extending adapter 126 is provided on the rear side of the floor brush housing 120, and the body 11 is configured to be movably connected to the adapter 126. The adapter 126 enables the floor brush assembly 12 to be flexibly rotated relative to the body 11, which is convenient for turning during the cleaning process.

[0122] It is understandable that the upper part of the adapter 126 is entirely used for connecting the fuselage 11, and the clean water tank 14 cannot extend to the upper part of the adapter 126. Figure 20 As shown, the position of the liquid storage chamber 140 corresponding to the adapter 126 is provided with a first avoidance portion 141 for avoiding the adapter 126, and the position of the first avoidance portion 141 is used to accommodate the body 11. The first avoidance portion 141 can be arranged in the middle position of the rear side of the clean water tank 14, and the clean water tank 14 can be constructed in an approximately U-shaped shape. By providing the first avoidance portion 141, the avoidance of the adapter 126 on the floor brush housing 120 is achieved, and an installation space is reserved on the clean water tank 14 for the adapter 126, so that the body 11 can be connected to the floor brush assembly 12.

[0123] In one embodiment of the present disclosure, Figure 20 As shown, the clean water tank 14 may be provided with a positioning portion 146, which may be a protruding structure provided on the rear side wall of the clean water tank 14, thereby forming the positioning portion 146 located in the first avoidance portion 141. Figure 18 As shown, a positioning groove 1203 adapted to the positioning portion 146 may be provided on the floor brush housing 120, and the positioning groove 1203 may be provided on the front side wall of the adapter 126. When installing the clean water tank 14, the user can quickly determine the installation position through the positioning portion 146 and the positioning groove 1203. The positioning portion 146 can form a guiding match with the positioning groove 1203, thereby reducing the difficulty of installing the clean water tank 14 and improving the user experience.

[0124] In one embodiment of the present disclosure, continue to refer to Figures 18 to 20, the top end face of the roller brush cover 122 is configured to be higher than the top end face of the floor brush housing 120. By adjusting the layout of the components in the inner cavity of the floor brush housing 120, the height of the inner cavity of the floor brush housing 120 is reduced, and the top end face of the floor brush housing 120 is lower than the top end face of the roller brush cover 122. The reduced height of the floor brush housing 120 can be compensated to the water tank 14 located above the floor brush housing 120, thereby further expanding the capacity of the water tank 14. A second avoidance portion 142 for avoiding the roller brush cover 122 is provided at the position of the water tank 14 corresponding to the roller brush cover 122. The second avoidance portion 142 can be provided on the front bottom surface of the water tank 14. Since the upper surface of the roller brush cover 122 presents an arc shape matching the roller brush 121, the second avoidance portion 142 can also be correspondingly provided as an arc groove, or can also be provided as an inclined plane groove. When the water tank 14 is installed on the floor brush housing 120, the roller brush cover 122 is located in the second avoidance portion 142 and does not squeeze the bottom surface of the water tank 14. By providing the second avoidance portion 142, the avoidance of the roller brush cover 122 is realized, and an installation space is reserved for the roller brush cover 122 on the water tank 14, so that the layout between the various structures of the floor brush assembly 12 is reasonable.

[0125] In an embodiment of the present disclosure, in order to monitor the water volume in the liquid storage cavity 140, a liquid level float can be provided in the liquid storage cavity 140. The liquid level float is mainly used to detect the water full, so as to provide a water full signal when the cleaning base station 2 automatically replenishes water to the water tank 14, so as to control the cleaning base station 2 to stop replenishing water in time. As Figure 20 shown, a protrusion 147 protruding from the bottom surface is provided on the bottom surface of the water tank 14. The liquid level float is configured to be located on the extension path of the protrusion 147, so that the liquid level float can be accommodated in the liquid storage cavity 140 at the corresponding position of the protrusion 147. As Figure 19 shown, a mating groove 1204 adapted to the protrusion 147 can be provided on the floor brush housing 120. When the water tank 14 is installed on the floor brush housing 120, the protrusion 147 is located in the mating groove 1204.

[0126] Since the overall shape of the water tank 14 is a flat shape with a large horizontal cross-sectional area and a low height, in order to ensure the accuracy of detection, the liquid level float needs to ensure a certain stroke. Therefore, the protrusion 147 is provided to protrude from the bottom surface of the water tank 14 to extend the movement path of the liquid level float; and since the top surface of the floor brush housing 120 is lower than the top end face of the roller brush cover 122, the part of the water tank 14 above the floor brush housing 120 has a greater thickness. Therefore, the protrusion 147 is provided at the bottom surface position of the water tank 14 corresponding to the floor brush housing 120, so as not to affect the upper part of the water tank 14, thereby providing a reasonable structural layout of the water tank 14.

[0127] In an embodiment of the present disclosure, as Figure 20As shown, a latch assembly 143 is provided on the water tank 14, and the water tank 14 is configured to be detachably connected to the floor brush housing 120 through the latch assembly 143. Two sets of latch assemblies 143 can be provided, and the two sets of latch assemblies 143 are respectively provided on both sides of the water tank 14.

[0128] Reference Figure 18 and Figure 19 , first mating members 1202 that cooperate with the latch assembly 143 can be provided on the inner walls of both sides of the floor brush housing 120. As Figure 20 shown, the latch assembly 143 can include an unlocking member 1431 and a second mating member 1432. When the water tank 14 is installed on the floor brush housing 120, the first mating member 1202 and the second mating member 1432 can be locked together, thereby fixing the water tank 14 on the floor brush housing. At this time, the unlocking member 1431 is exposed on the outer side wall of the water tank 14. When it is necessary to disassemble the water tank 14, the user can simultaneously press the unlocking members 1431 on both sides of the water tank 14 with both hands, and the two unlocking members 1431 respectively push the two second mating members 1432 to move to a position where they are unlocked from the first mating member 1202. At this time, the user can easily remove the water tank 14 from the floor brush housing 120.

[0129] The present disclosure provides the latch assembly 143, thereby realizing simple disassembly and assembly of the water tank 14. If only one latch assembly 143 is provided, there may be an obstacle hitting the latch assembly 143 during the cleaning process, which may cause the fixing of the water tank 14 to fail and the water tank 14 to fall off. By providing two latch assemblies 143, the present disclosure enables the user to have to operate with both hands to remove the water tank 14, effectively preventing accidental touch and improving the fixing stability of the water tank 14.

[0130] When the roller brush 121 rotates in the roller brush cavity, the dirt adsorbed on its surface will be thrown to the inner wall of the roller brush cover 122 under the action of centrifugal force, resulting in the dirt adhering to the inner wall of the roller brush cover 122. Over time, it is easy to cause the growth of bacteria and generate odors. In an embodiment of the present disclosure, reference Figure 22 and Figure 23 , in order to clean the inner wall of the roller brush cover 122, the roller brush cover 122 is configured to move between a first position and a second position relative to the floor brush housing 120; there is a space for the roller brush cover 122 to move between the roller brush cover 122 and the water tank 14, and the movement space ensures that the roller brush cover 122 will not squeeze the water tank 14 during the movement process.

[0131] When in the first position, as Figure 22 shown, there is a first contact area between the roller brush cover 122 and the roller brush 121; when in the second position, as Figure 23As shown, there is a second contact area between the roller brush cover 122 and the roller brush 121; wherein, the first contact area is greater than or equal to zero and less than the second contact area. A roller brush cover driving member 128 is provided in the floor brush assembly 12, and the roller brush cover driving member 128 can drive the roller brush cover 122 to move between a first position and a second position.

[0132] When the first contact area is equal to zero, the inner wall of the roller brush cover 122 is configured to be separated from the roller brush 121, which prevents the roller brush cover 122 from affecting the rotation and cleaning work of the roller brush 121 during normal cleaning or self-cleaning of the cleaning device. When the first contact area is greater than zero, the inner wall of the roller brush cover 122 is in partial contact and cooperation with the roller brush 121. For example, the rear edge of the roller brush cover 122 can be in line contact with the roller brush 121, or a small part of the rear end of the roller brush cover 122 can be attached to the roller brush 121. The specific size of the first contact area depends on the specific shape of the roller brush cover 122 and also on the fluffiness of the roller brush 121. A brand-new roller brush 121 will have more fluffy bristles, and the first contact area will be larger at this time; after the roller brush 121 has been used for a period of time, the bristles are no longer fluffy, the diameter of the roller brush 121 decreases, and the first contact area also decreases accordingly.

[0133] The size of the second contact area depends on the area of the inner wall of the roller brush cover 122. When the roller brush cover 122 is in the second position, the inner wall of the roller brush cover 122 is almost completely in contact and cooperation with the roller brush 121. When the roller brush 121 rotates, it can generate friction with the inner wall of the roller brush cover 122 in the second position, thereby cleaning the dirt on the inner wall of the roller brush cover 122. In this way, the inner wall of the roller brush cover 122 is cleaned by the roller brush 121, avoiding manual cleaning of the roller brush cover 122 by the user and also preventing dirt from remaining on the inner wall of the roller brush cover 122. In order to enable the inner wall of the roller brush cover 122 to be fully cleaned, when in the second position, the second contact area between the roller brush cover 122 and the roller brush 121 is not less than 90% of the area of the inner wall of the roller brush cover 122. Preferably, the inner wall of the roller brush cover 122 is in full contact with the roller brush 121, and the second contact area is 100% of the area of the inner wall of the roller brush cover 122.

[0134] The present disclosure enables the roller brush cover 122 to work in a first position or a second position relative to the floor brush housing 120, and when the roller brush cover 122 is in the second position, its inner wall can be in contact and cooperation with the roller brush 121, thereby realizing the cleaning of the inner wall of the roller brush cover 122 by the roller brush 121. This improves the automation level of the cleaning device, and the user no longer needs to manually clean the inner wall of the roller brush cover, optimizing the user experience.

[0135] Further, the roller brush cover 122 can move between a first position and a second position along an arc-shaped movement trajectory. As described above, arc-shaped buckles 1222 are respectively provided on both sides of the roller brush cover 122, and two guiding grooves adapted to the arc-shaped buckles 1222 can be provided on the floor brush housing 120. The two arc-shaped buckles 1222 can move in the guiding grooves along the arc-shaped movement trajectory. The use of the arc-shaped movement trajectory is beneficial to making the inner wall of the roller brush cover 122 fit together with the roller brush 121, because the roller brush 121 is a rolling body and has a circumferential surface in a columnar or cylindrical shape. By adopting the movement mode of the arc-shaped movement trajectory, it can be ensured that the inner wall of the roller brush cover 122 fits together with the outer peripheral surface of the roller brush 121 as much as possible, so as to clean the inner wall of the entire roller brush cover 122 as much as possible, especially the inner wall that is prone to sticking dirt.

[0136] In an embodiment of the present disclosure, the liquid in the water tank 14 can provide clean water or cleaning liquid for cleaning to the roller brush 121. Refer to Figure 22 , a drainage part 127 is provided in the floor brush assembly 12. The drainage part 127 extends in the direction of the roller brush 121, so that the liquid in the water tank 14 can flow to the roller brush 121 through the drainage part 127 to moisten the roller brush 121.

[0137] Refer to Figure 21 , an extension part 1223 is provided on the roller brush cover 122. The extension part 1223 is configured to extend downward from top to a position adjacent to the drainage part 127 and encloses a liquid outlet with the drainage part 127. After the liquid flows out of the water tank 14, it is drained by the drainage part 127 to the liquid outlet and flows out of the liquid outlet to the roller brush 121. Specifically, an extension part 1223 extending in the direction of the drainage part 127 is provided at the position of the roller brush cover 122 corresponding to the drainage part 127. The extension part 1223 is located above the drainage part 127 and has a predetermined interval from the drainage part 127. The two enclose a liquid outlet, which enables the liquid flowing out of the water tank 14 to flow along the drainage part 127 and finally flow out to the surface of the roller brush 121 through the liquid outlet. In the present disclosure, a liquid outlet is formed between the extension part 1223 and the drainage part 127. By controlling the size and position of the liquid outlet, it can be avoided that the roller brush 121 throws dirt onto the water tank 14 and the drainage part 127 during rotation, avoiding problems such as blockage.

[0138] The present disclosure also provides a control method for a cleaning system, which can be applied to the cleaning system described above, or a cleaning system including the cleaning base station 2 and the cleaning device 1 described above. Refer to Figure 24, the control unit can send a water supply operation instruction. The water supply operation is an operation in which the cleaning base station 2 supplies water to the cleaning device 1 through the water supply valve assembly 23, and specifically may include: injecting cleaning liquid into the clean water tank 14, injecting clean water into the clean water tank 14, injecting clean water into the sewage tank 13, flushing the sewage tank 13, etc. Since water pressure impact will generate impact on the cleaning device 1 during the water supply operation, it is necessary to lock the cleaning device 1 on the cleaning base station 2 through the locking assembly before starting the water supply.

[0139] Specifically, the control method of the cleaning system includes:

[0140] Locking step: controlling the locking assembly to move to the locking position based on the first signal; wherein, the first signal is a water supply operation signal, and the water supply operation signal can be a signal for injecting cleaning liquid into the clean water tank 14, or a signal for injecting clean water into the clean water tank 14, or a signal for injecting clean water into the sewage tank 13, or a signal for flushing the sewage tank 13, etc. A signal for energizing the electromagnet 243 is sent based on the water supply operation signal. After being energized, the electromagnet 243 can drive the locking mechanism 241 to move to the locking position.

[0141] In an embodiment of the present disclosure, as Figure 24 shown, the locking step further includes a detection step of detecting whether the locking assembly is locked in place. Specifically, it can be detected whether the locking assembly is locked in place through a trigger member 245 such as a microswitch: when locked in place, when the locking mechanism 241 is in the locking position, the trigger member 245 can come into contact with the iron core 242 and thus be triggered by the iron core 242; conversely, when not locked in place, that is, when the locking mechanism 241 is still in the unlocking position, the trigger member 245 is separated from the iron core 242 and the trigger member 245 cannot be triggered.

[0142] Water supply step: when locked in place, controlling the cleaning base station 2 to perform a water supply operation through the water supply valve assembly 23. Only when locked in place, that is, when the trigger member 245 is triggered, can the water supply step be executed. During the entire process of the water supply operation, the locking assembly always remains in the locking position, thereby ensuring that the cleaning device 1 can be stably locked on the cleaning base station 2 during the water supply operation. After the water supply operation is completed, controlling the cleaning base station 2 to close the water supply valve assembly 23, when no liquid flows out of the water supply valve assembly 23, the cleaning device 1 can be unlocked.

[0143] Unlocking steps: Control the locking component to move to the unlocking position based on the second signal; wherein, the second signal is a signal indicating that the water filling is completed, and the signal indicating that the water filling is completed can be that the water filling time reaches the set duration, or the signal that the water tank 14 is full of water, or the signal that the sewage tank 13 is full of water, etc. Send a signal to cut off the power supply of the electromagnet 243 based on the second signal. After the power supply of the electromagnet 243 is cut off, the electromagnetic force acting on the iron core 24 disappears, and the locking mechanism 241 can be driven by the elastic force to move to the unlocking position.

[0144] In the case where the locking component moves to the locking position and the unlocking position smoothly every time the power is turned on and off, only the foregoing locking steps, water filling steps, and unlocking steps need to be sequentially executed to complete the water filling operation instruction. However, in actual application scenarios, due to reasons such as the locking component malfunctioning, the docking between the cleaning device 1 and the water supply valve assembly 23 being inaccurate, and the signal not being transmitted smoothly, the locking component may not be locked in place after the power is turned on, and the locking component may not be unlocked in place after the power is turned off. Based on this, as Figure 24 shown, in an embodiment of the present disclosure, the locking step further includes:

[0145] When it is detected that the locking component is not locked in place, control the locking component to repeatedly execute the unlocking step and the locking step. After the electromagnet 243 is powered on, if the trigger 245 is not triggered, it means that the locking component is not locked in place, and at this time, the power supply of the electromagnet 243 needs to be cut off and then powered on again.

[0146] When it is detected that the repeated locking is in place, continue to execute the water filling step. If the trigger 245 emits a trigger signal after the electromagnet 243 is powered on for the second time, it means that the second locking is in place. The cleaning device 1 is stably locked on the cleaning base station 2, so the water filling step can be continued, that is, control the cleaning base station 2 to perform the water filling operation through the water supply valve assembly 23.

[0147] When it is detected that the repeated locking is not in place, cancel the execution of the water filling step. If the trigger 245 is still not triggered after the electromagnet 243 is powered on for the second time, it means that the second locking is still not in place, and at this time, the execution of the water filling operation instruction needs to be stopped. It can be understood that if the water filling step is still executed when the locking is not in place, due to the insufficient stability of the docking position between the water supply valve assembly 23 and the cleaning device 1, there is a risk of water overflow.

[0148] After canceling the execution of the water supply step, charging and alarming can be performed. Among them, the cleaning device 1 needs to be charged in the cleaning base station 2 itself, and the inability to successfully lock will not affect the charging operation. Therefore, the cleaning base station 2 can be controlled to supply power to the cleaning device 1 normally. The cleaning device 1 or the cleaning base station 2 can alarm by turning on the alarm light, emitting an alarm sound, or sending an alarm message to the user's mobile phone, etc., so as to remind the user to come and check and repair the locking component.

[0149] In an embodiment of the present disclosure, referring to Figure 25 , after controlling the locking component to move to the unlocking position based on the second signal, the unlocking step further includes a detection step of detecting whether the locking component is unlocked in place. When unlocked in place, the locking mechanism 241 is in the unlocking position, the triggering member 245 is separated from the iron core 242, and the triggering member 245 will not be triggered; on the contrary, when the unlocking is not in place, the triggering member 245 can come into contact with the iron core 242 and thus be triggered by the iron core 242.

[0150] When it is detected that the locking component is not unlocked in place, control the locking component to repeat the locking step and the unlocking step. After the electromagnet 243 is powered off, if the triggering member 245 is still in the triggered state, it means that the locking component is not unlocked in place. At this time, the electromagnet 243 needs to be powered on and then powered off again.

[0151] It can be understood that after each repetition of the locking step and the unlocking step, the position of the locking component will be detected: if it is detected that the repeated unlocking is in place, it means that after the last power-off, the locking component has successfully reset to the unlocking position, and the program can be ended at this time; if it is detected that the repeated unlocking is still not in place, the locking step and the unlocking step can be repeated again.

[0152] In a specific embodiment of the present disclosure, a number threshold can be set. When the number of cycles of repeating the locking step and the unlocking step does not exceed this number threshold, the cycle continues in the case of unlocking not in place; when the number of cycles of repeating the locking step and the unlocking step is higher than this number threshold, the repetition is no longer continued. Specifically, the number threshold can be set to 1 time: if the unlocking is not in place after the first repetition, a second repetition can be performed; if the unlocking is still not in place after the second repetition, since the number of repetitions has exceeded the number threshold, no further repetition is performed.

[0153] When it is detected that the repeated unlocking is not in place, the detection step of detecting whether the locking component is unlocked in place is continuously executed. When the locking component is still not unlocked in place after the last repetition, the attempt of powering on and then powering off will not be repeated. Instead, the electromagnet 243 will be controlled to remain in the powered-off state, and the position information of the locking component will be continuously detected. It can be understood that if the locking component is still in the locked position when the electromagnet 243 is powered off, the locking component may be stuck and may return to its original position by natural springback after being stationary for a period of time. Therefore, there is no need to keep repeating the attempt of powering on and then powering off, but only the detection step needs to be continuously executed.

[0154] In one embodiment of the present disclosure, the locking step, the water supply step, and the unlocking step are executed during the self-cleaning operation of the cleaning system. Among them, the self-cleaning operation includes: the first type of operation that requires the execution of the water supply step and the second type of operation that does not require the execution of the water supply step. Specifically, the self-cleaning operation of the cleaning system may include multiple operation steps, such as: injecting clean water into the clean water tank 14, flushing the sewage tank 13, self-cleaning the roller brush 121, emptying the sewage tank 13, etc. Among them, the operation steps that need to be completed by the water supply valve assembly 23 (such as: injecting clean water into the clean water tank 14, flushing the sewage tank 13, etc.) are classified as the first type of operation; the operation steps that do not use the water supply valve assembly 23 (such as: self-cleaning the roller brush 121, emptying the sewage tank 13, etc.) are classified as the second type of operation.

[0155] During the self-cleaning operation, the first type of operation and the second type of operation may be alternately executed, or multiple first type of operations or multiple second type of operations may be continuously executed. When executing the first type of operation, the aforementioned locking step, water supply step, and unlocking step need to be executed in sequence. Among them, during the execution of the unlocking step, when it is detected that the locking component is not unlocked in place, the locking component is controlled to repeatedly execute the locking step and the unlocking step during the second type of operation, while continuing the self-cleaning operation.

[0156] When the unlocking is not in place, it means that the locking component is still in the unlocked position. If the next self-cleaning operation to be performed is still the first type of operation, the locking step and the unlocking step should not be repeated, and the locking component only needs to maintain its current state to stably lock the cleaning device 1 on the cleaning base station 2. If the next self-cleaning operation to be performed is the second type of operation, the second type of operation can be executed while repeatedly executing the locking step and the unlocking step, that is, repeatedly powering on and off the electromagnet 243 to try to reset the locking component to the unlocked position. At this time, repeating the attempt will not affect the self-cleaning operation because the second type of operation does not use the water supply valve assembly 23, and whether it is locked or not will not affect the second type of operation.

[0157] As described above, if the locking component fails to unlock completely after multiple attempts of power-on and power-off, and the number of repetitions reaches the threshold, no further repetition will be performed. Instead, the electromagnet 243 will be controlled to remain in the power-off state, and the position information of the locking component will be continuously detected. During this process, both the first type of operation and the second type of operation can proceed normally without terminating the program due to the incomplete unlocking of the locking component.

[0158] After the self-cleaning operation is completed, when it is detected that the locking component fails to unlock completely, an alarm signal is controlled to be issued. Specifically, after the self-cleaning operation is completed, charging and alarming can be performed. Specifically, the inability to unlock completely will not affect the charging operation. Therefore, the cleaning base station 2 can be controlled to supply power to the cleaning device 1 normally. The cleaning device 1 or the cleaning base station 2 can alarm by means of lighting an alarm lamp, emitting an alarm sound, or sending an alarm message to the user's mobile phone, etc., so as to remind the user to come and check and repair the locking component.

[0159] In an embodiment of the present disclosure, the maximum power-on time of the electromagnet 243 ≤ 60 seconds. The continuous power-on time of the electromagnet 243 should not exceed one minute. If the power-on time of the electromagnet 243 is too long, it will overheat, easily reducing its lifespan and causing the locking component to malfunction. During the self-cleaning operation, the operation time of each first type of operation that requires the use of the water inlet valve assembly 23 should not be too long either. The single locking time of the locking component does not exceed 60s, and each first type of operation should be completed within 60s.

[0160] In an embodiment of the present disclosure, the cleaning device 1 includes a clean water tank 14, and the water inlet valve assembly 23 includes a second water valve 232 for docking with the clean water tank 14. The water inlet steps include:

[0161] The first liquid injection step: Based on the first liquid addition instruction, control the cleaning base station 2 to inject cleaning liquid into the clean water tank 14 through the second water valve 232;

[0162] The second liquid injection step: Based on the second liquid addition instruction, control the cleaning base station 2 to inject clean water into the clean water tank 14 through the second water valve 232;

[0163] Among them, the first liquid injection step and the second liquid injection step are not executed simultaneously. In the cleaning base station 2, the cleaning liquid and the clean water are stored in different containers respectively, and the liquid is conveyed to the second water valve 232 through their respective corresponding pipelines. The two pipelines converge at the second water valve 232, and thus are connected to the clean water tank 14 through the second water valve 232. Since the water addition amount of the clean water is significantly greater than the liquid addition amount of the cleaning liquid, correspondingly, the clean water addition pressure will also be much greater than the cleaning liquid addition pressure. If the first liquid injection step and the second liquid injection step are executed simultaneously, it will be difficult for the cleaning liquid to be smoothly pumped into the clean water tank 14. Therefore, it is necessary to stagger the execution of the first liquid injection step and the second liquid injection step. For example, the first liquid addition instruction can be sent first, so as to control the cleaning base station 2 to inject the cleaning liquid into the clean water tank 14 through the second water valve 232; after the injection of the cleaning liquid is completed, the second liquid addition instruction is sent again, so as to control the cleaning base station 2 to inject the clean water into the clean water tank 14 through the second water valve 232.

[0164] In a specific embodiment of the present disclosure, the cleaning liquid and the clean water can be mixed after being injected into the clean water tank 14, and the concentration of the mixed solution should be controlled within a certain range. Specifically, the ratio of the cleaning liquid to the clean water is about 1:50. The concentration of the cleaning liquid should not be too high, otherwise there will be residues of the cleaning liquid on the cleaned working surface; the concentration of the cleaning liquid should not be too low, otherwise the cleaning effect will be insufficient. It can be understood that the addition amount of the cleaning liquid is closely related to the actual solution amount in the clean water tank 14: when there is still remaining liquid in the clean water tank 14, the required addition amount of the cleaning liquid is small; when the clean water tank 14 is basically emptied, the required addition amount of the cleaning liquid is large.

[0165] In this embodiment, a liquid level float can be arranged in the liquid storage cavity 140 of the clean water tank 14, and the liquid level float is mainly used to detect the full water level. Since the current liquid level situation in the clean water tank 14 cannot be directly monitored, in order to determine the addition amount of the cleaning liquid, the first liquid injection step includes:

[0166] Obtain the working duration of the cleaning device 1;

[0167] When the working duration of the cleaning device 1 is greater than or equal to the working duration threshold, determine the current liquid injection duration as the maximum liquid injection duration. Specifically, the working duration threshold of the cleaning device 1 is the maximum endurance time of the clean water tank 14. For example, the working duration threshold can be 40 minutes. When the working duration of the cleaning device 1 is greater than or equal to 40 minutes, it means that the clean water tank 14 has been emptied, so the current cleaning liquid injection amount can be determined as the maximum injection amount. The current liquid injection duration of the peristaltic pump for injecting the cleaning liquid is the maximum liquid injection duration. For example, the peristaltic pump can be controlled to work for 10 seconds, and 17 milliliters of cleaning liquid can be pumped in 10 seconds, and 17 milliliters of cleaning liquid is the maximum injection amount of the cleaning liquid.

[0168] When the working duration of the cleaning device 1 is less than the working duration threshold, the current liquid injection duration is calculated based on the ratio between the working duration of the cleaning device 1 and the working duration threshold, and the maximum liquid injection duration. For example: the working duration of the cleaning device 1 is 20 minutes, which is less than the working duration threshold (40 minutes), and the ratio between the working duration of the cleaning device 1 and the working duration threshold is 0.5. It can be considered that there is still 50% of the remaining liquid in the clean water tank 14; multiplying the maximum liquid injection duration (10 seconds) by the above ratio (0.5) can obtain the current liquid injection duration of 5s, and the current cleaning liquid injection volume is 8.5 milliliters.

[0169] Based on the current liquid injection duration, a first liquid addition instruction is sent. The cleaning liquid is pumped according to the calculated current liquid injection duration. After the liquid injection is completed, a second liquid addition instruction can be sent to control the cleaning base station 2 to inject clean water into the clean water tank 14 through the second water valve 232 until the liquid level float detects a full water signal. This control method only needs to calculate the current liquid injection duration of the cleaning liquid, without the need to calculate the liquid injection duration of the clean water additionally. At the same time, the solution in the clean water tank 14 can basically maintain a constant concentration, and the cleaning device 1 can achieve a stable cleaning effect.

[0170] Application scenario 1

[0171] In the embodiment where the cleaning device of the present disclosure is a handheld floor washer, when the user uses the floor washer for cleaning work, the user can push the floor washer to move on the working surface and clean the working surface. After cleaning, the user can place the floor washer on the cleaning base station 2 for maintenance, such as charging, replenishing water, discharging sewage, etc.

[0172] The cleaning base station 2 includes a base 21 extending in the height direction and a tray 22 extending to one side of the base 21. Among them, the base 21 is used to dock with the body 11 of the floor washer, and the sewage tank 13 provided on the body 11 can be docked to the sewage discharge groove assembly 211 on the base 21. The dirt in the sewage tank 13 can be discharged to the sewage discharge groove assembly 211 under the action of gravity, and the sewage discharge groove assembly 211 can perform subsequent discharge treatment on the dirt.

[0173] The tray 22 is used to support the floor brush assembly 12 of the floor washer. A charging port 125 can be provided at the bottom of the floor brush assembly 12, and a charging part is provided on the tray 22. When the floor washer is docked with the cleaning base station 2, the protruding charging part on the tray 22 can extend into the charging port 125, and a circuit connection can be formed between the two, so as to realize charging the floor washer by the cleaning base station 2.

[0174] A notch 15 is also formed at the bottom of the floor brush assembly 12, and a first docking portion 151 and a second docking portion 152 are provided in the notch 15; a water supply valve assembly 23 higher than the top end face is arranged on the tray 22, and the water supply valve assembly 23 includes a first water valve 231 and a second water valve 232 arranged adjacent to each other. The water supply valve assembly 23 can be docked into the notch 15, and the first water valve 231 is docked with the first docking portion 151, and the second water valve 232 is docked with the second docking portion 152, so as to flush the sewage tank 13 of the floor washer and replenish water to the clean water tank 14 of the floor washer respectively.

[0175] In the present disclosure, by arranging both the first water valve 231 and the second water valve 232 on the tray 22, both water valves are located at the lowest position of the cleaning base station 2, and the floor washer can be stably docked under its own gravity. In addition, the water at the water valve can be received by the tray 22 and will not affect other components. For example, the charging contacts 224 on the charging part can be arranged at a position higher than the water supply valve assembly 23, so as to prevent the water flow at the first water valve 231 and the second water valve 232 from flowing to the charging contacts 224, effectively preventing leakage or short - circuit accidents and improving the safety of the cleaning base station 2. In addition, the first water valve 231 and the second water valve 232 are adjacent to each other, thereby improving the integration degree of the water supply valve assembly 23. Only one notch 15 for docking with the water supply valve assembly 23 needs to be formed on the floor brush assembly 12, without separately opening holes for docking the first water valve 231 and the second water valve 232.

[0176] Application Scenario 2

[0177] In an embodiment where the cleaning device in the present disclosure is a handheld floor washer, when the user uses the floor washer for cleaning work, the user can push the floor washer to move on the working surface and clean the working surface. After cleaning, the user can place the floor washer on the cleaning base station 2 for maintenance, such as charging, water replenishment, sewage discharge, etc.

[0178] The cleaning base station 2 includes a base 21 extending in the height direction and a tray 22 extending to one side of the base 21. Among them, a water supply valve assembly 23 is arranged on the tray 22. The water supply valve assembly 23 includes a first water valve 231 and a second water valve 232 arranged adjacent to each other, and further includes a mounting seat 233. Two adjacent mounting holes 230 are formed on the mounting seat 233, and the first water valve 231 and the second water valve 232 are respectively located in the corresponding mounting holes 230.

[0179] A locking assembly is arranged on the mounting seat 233, and the locking assembly can be arranged between the first water valve 231 and the second water valve 232. When moving to the locking position, the locking assembly can cooperate with the floor brush assembly 12 of the floor washer to lock the floor brush assembly 12 on the tray 22; when moving to the unlocking position, the locking assembly can disengage from the floor brush assembly 12.

[0180] The locking assembly includes a locking mechanism 241 hinged to the mounting base 233 and a driving mechanism composed of an electromagnet 243 and an iron core 242. The locking mechanism 241 moves between a locking position and an unlocking position under the action of the driving mechanism. The locking end of the locking mechanism 241 can be configured as a hook 2410. When in the locking position, the hook 2410 can lock the floor scrubbing assembly 12 on the tray 22; when in the unlocking position, the hook 2410 can be separated from the floor scrubbing assembly 12.

[0181] In the energized state, the iron core 242 located in the inner cavity of the electromagnet 243 can move under the action of electromagnetic induction and drive the locking mechanism 241 to rotate, so that the locking mechanism 241 moves from the unlocking position to the locking position. The driving mechanism further includes a first elastic member 244 pre-pressed between the iron core 242 and the electromagnet 243. When the electromagnet 243 is de-energized, the iron core 242 is no longer subjected to electromagnetic force, and the iron core 242 is configured to drive the locking mechanism 241 to move from the locking position to the unlocking position under the elastic force of the first elastic member 244.

[0182] The present disclosure improves the docking stability between the floor washer and the cleaning base station 2 by providing a locking assembly. Specifically, the locking assembly can firmly lock the floor washer on the base body of the station, and the water pressure when the cleaning base station 2 supplies water to the floor washer will not lift the floor washer, thereby preventing water leakage. In addition, directly installing the locking assembly on the water inlet valve assembly 23 is beneficial to balancing the water pressure impact during water inlet and further improves the docking stability.

[0183] Application Scenario Three

[0184] In an embodiment where the cleaning device of the present disclosure is a handheld floor washer, when the user uses the floor washer for cleaning work, the user can push the floor washer to move on the working surface and clean the working surface.

[0185] The floor washer includes a body 11 and a floor scrubbing assembly 12 connected to the bottom of the body 11. The floor scrubbing assembly 12 includes a floor scrubbing housing 120, a roller brush cover 122, a roller brush 121, and a clean water tank 14. Among them, the roller brush cover 122 is configured to be detachably connected to the floor scrubbing housing 120 according to a preset disassembly and assembly path, and is configured to enclose a roller brush cavity with the floor scrubbing housing 120. The roller brush 121 is located in the roller brush cavity and is configured to be rotatably connected to the floor scrubbing housing 120.

[0186] The water tank 14 is detachably connected to the floor brush housing 120. The water tank 14 has a liquid storage cavity 140, and the liquid storage cavity 140 is configured to extend from a position corresponding to the floor brush housing 120 to a position on the disassembly and assembly path of the roller brush cover 122. The liquid storage cavity 140 can be installed on the top of the floor brush housing 120 and extend forward above the roller brush cover 122. The disassembly and assembly path of the roller brush cover 122 can be vertically upward, and the liquid storage cavity 140 extending above the roller brush cover 122 has a larger capacity.

[0187] To maximize the capacity of the liquid storage cavity 140, it is necessary to maximize the projected area of the water tank 14 on the working surface. The liquid storage cavity 140 can be configured to cover the top end face of the floor brush housing 120. In this case, the liquid storage cavity 140 can completely cover the upper surface of the roller brush cover 122, and the top end face of the water tank 14 encloses the entire upper surface of the floor brush assembly 12, thereby maximizing the capacity of the liquid storage cavity 140.

[0188] In the present disclosure, by arranging the water tank 14 on the floor brush housing 120, the weight of the body 11 is reduced, making it easier for the user to push the floor washer. In addition, the water tank 14 arranged on the floor brush housing 120 increases the downward pressure of the floor brush assembly 12, thereby improving the cleaning effect of the roller brush 121 on the working surface. The liquid storage cavity 140 of the water tank 14 in the present disclosure extends to a position on the disassembly and assembly path of the roller brush cover 122, realizing that the water tank 14 can be integrated with the roller brush cover 122 on the floor brush assembly 12 at the same time, and the capacity of the outwardly extending liquid storage cavity 140 is also increased. The amount of water stored in the water tank 14 is sufficient to complete a full-house cleaning, and the user does not need to replenish water repeatedly, improving the user experience.

[0189] Application Scenario Four

[0190] In an embodiment where the cleaning device in the present disclosure is a handheld floor washer, when the user uses the floor washer for cleaning work, the user can push the floor washer to move on the working surface and clean the working surface. After cleaning, the user can place the floor washer on the cleaning base station 2 for maintenance, such as charging, replenishing water, discharging sewage, etc.

[0191] In the self-cleaning operation, an instruction to flush the sewage tank 13 needs to be executed:

[0192] Locking step: Energize the electromagnet 243, and the locking mechanism 241 moves to the locking position; after the first power-on, if it is detected that the locking assembly is not locked in place, the electromagnet 243 is de-energized and then powered on again, and it is detected that the repeated locking is in place;

[0193] Water filling step: When the locking is in place, control the cleaning base station 2 to flush the sewage tank 13 through the first water valve 231. During the whole process of flushing, the locking assembly always remains in the locked position, so as to ensure that the cleaning device 1 can be stably locked on the cleaning base station 2 during the flushing process. After the flushing is completed, control the cleaning base station 2 to close the water filling valve assembly 23. When no more liquid flows out of the water filling valve assembly 23, the cleaning device 1 does not need to be locked continuously.

[0194] Unlocking step: Cut off the power supply of the electromagnet 243, and the locking mechanism 241 moves towards the unlocking position; after the first power cut-off, it is detected that the unlocking of the locking assembly is not in place. The roller brush 121 of the cleaning device 1 is performing self-cleaning, that is, performing the second type of operation, and the state of the locking assembly will not affect the second type of operation. Therefore, the electromagnet 243 can be repeatedly powered on and off. After repeating 2 times, the unlocking of the locking assembly is still not in place, and no more repetition is performed. Instead, the electromagnet 243 will be controlled to remain in the power-off state, and the position information of the locking assembly will be continuously detected.

[0195] After the self-cleaning operation is completed, it is detected that the unlocking of the locking assembly is still not in place, and charging and alarming are controlled to remind the user to come and check and repair the locking assembly.

[0196] The above has described the embodiments of the present disclosure. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other ordinary technicians in the technical field to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
