Description

Technical Field

[0001] This disclosure relates to the field of clean technology, specifically to a clean base station; this disclosure also relates to a clean system; this disclosure further relates to a control method for a clean system. Background Technology

[0002] With the development of social productivity, people's living standards have also improved. With their material needs met, people have begun to use various tools to reduce labor and improve their quality of life, leading to the emergence of household cleaning equipment. After completing their cleaning tasks, the equipment needs to be placed on a cleaning base station for maintenance. The cleaning base station can refill the clean water tank and flush the wastewater tank.

[0003] Because the water pressure supplied by the cleaning base station to the cleaning equipment is relatively high, the cleaning equipment may be lifted up by the water at the docking point. The weight of the cleaning equipment is insufficient to ensure the sealing of the docking point, resulting in water leakage. How to improve the stability of the docking between the cleaning equipment and the cleaning base station, thereby preventing water leakage, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] This disclosure aims to address the problems existing in the prior art by providing a clean base station, a clean system, and a control method thereof.

[0050] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0051] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0052] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0053] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0054] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0055] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0056] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0057] This disclosure provides a cleaning base station, including: a base station body, a water inlet valve assembly, and a locking assembly. The base station body is configured to house cleaning equipment, which can be a floor scrubber, a cleaning machine, or other equipment used for cleaning floors, sofas, carpets, etc.

[0058] The cleaning equipment may include a main body and a floor brush assembly connected to the main body. For example, the cleaning equipment disclosed herein may be a floor scrubber. When using the floor scrubber for cleaning, the user can move the main body of the floor scrubber on the ground and use the floor brush assembly to clean the ground. The cleaning equipment may also include a wastewater tank and a clean water tank. The clean water tank can provide liquid for the floor brush assembly to clean the work surface; the wastewater tank can be used to store the dirt after cleaning for convenient subsequent centralized treatment.

[0059] Cleaning base stations can be used as storage carriers for cleaning equipment before and after use. Cleaning base stations include at least functions such as charging, draining, and refilling water for cleaning equipment. For example, after a user completes the cleaning work with the cleaning equipment, the user can place the cleaning equipment on the cleaning base station to connect with it. The cleaning base station will then charge, drain, and refill water for the cleaning equipment, reducing the user's daily cleaning workload.

[0060] The water supply valve assembly includes a water valve unit mounted on the base station body for interfacing with cleaning equipment. The water valve unit may consist of a single water valve, or it may include a first water valve and a second water valve. The first water valve can communicate with the wastewater tank of the cleaning equipment to flush the wastewater tank; the second water valve can communicate with the clean water tank of the cleaning equipment to replenish the clean water tank. The X and Y axes are defined vertically in a plane, and the water valve unit extends along the X-axis. In embodiments where the water valve unit includes a first water valve and a second water valve, the first and second water valves are arranged along the X-axis.

[0061] The locking assembly is configured to be located in the X-axis and / or Y-axis direction of the water inlet valve assembly. Specifically, the locking assembly is configured to move between a locked position and an unlocked position; when in the locked position, the locking assembly is configured to lock the cleaning device onto the base station body; when in the unlocked position, the locking assembly is configured to unlock the cleaning device from the base station body.

[0062] This disclosure improves the stability of the connection between the cleaning equipment and the cleaning base station by incorporating a locking component. Specifically, the locking component securely locks the cleaning equipment onto the base station body, preventing water pressure from the base station from lifting the cleaning equipment and thus preventing leakage. Furthermore, the locking component is positioned along the X-axis and / or Y-axis of the water inlet valve assembly, and the locking position of the cleaning equipment is directly related to the water inlet valve assembly. This helps to balance the water pressure impact during water supply, effectively ensuring stable connection at the water inlet valve assembly and further enhancing the overall connection stability.

[0063] The specific embodiments of this disclosure will now be described with reference to the accompanying drawings. It should be noted that this disclosure also provides a cleaning system. To maintain brevity, the cleaning base station and cleaning equipment will be introduced together with the description of the specific structure and working principle of the cleaning system, and will not be described separately.

[0064] This disclosure provides a cleaning system, with reference to Figure 1 The cleaning system includes: cleaning equipment 1 and cleaning base station 2. For example... Figure 1 As shown, the cleaning device 1 includes a body 11 and a floor brush assembly 12 connected to the body 11. Specifically, the floor brush assembly 12 is connected to the bottom of the body 11. The floor brush assembly 12 is used to clean the work surface and is configured to extend a certain length from the bottom of the body 11 to the work surface. That is, when the cleaning device 1 is working, the floor brush assembly 12 is in contact with the work surface, and the bottom of the body 11 is at a certain height above the work surface.

[0065] In one embodiment of this disclosure, the cleaning device 1 can be a handheld cleaning device. During operation, the user can hold the handle 10 above the main body 11 to move the cleaning device 1 across the work surface. Alternatively, the user can provide external force to control the direction of movement of the cleaning device 1, and the cleaning device 1, with its built-in walking mechanism, can move automatically. Simultaneously, the cleaning components on the floor brush assembly 12 can wipe away stains on the work surface, thereby cleaning the work surface.

[0066] The cleaning equipment 1 also includes a wastewater tank 13 and a clean water tank 14. The clean water tank 14 provides liquid for the floor brush assembly 12 to clean the work surface. Specifically, the floor brush assembly 12 may also include a spraying mechanism that sprays clean water or cleaning fluid from the clean water tank 14 onto the cleaning components or directly onto the work surface to be cleaned, thereby ensuring cleaning effectiveness. The wastewater tank 13 is used to store dirt after cleaning. Specifically, the floor brush assembly 12 may also include a suction port, which allows dirt to be sucked into the wastewater tank 13 for storage during cleaning, facilitating subsequent centralized treatment.

[0067] See Figures 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 hold the cleaning equipment 1. Specifically, the cleaning base station 2 can be used as a storage carrier for the cleaning equipment 1 before and after operation. The cleaning base station 2 includes functions such as charging, draining, and replenishing water for the cleaning equipment 1. For example, after a user completes cleaning work with the cleaning equipment 1, the user can place the cleaning equipment 1 on the cleaning base station 2 to connect with it. The cleaning base station 2 will then charge, drain, and replenish water for the cleaning equipment 1, reducing the user's daily cleaning workload.

[0068] like Figure 1 As shown, the base station body includes a base 21 and a tray 22. The base 21 is configured to extend in the height direction; the tray 22 is configured to extend horizontally toward one side of the base 21 and is configured to support the floor brush assembly 12 of the cleaning device 1. In this disclosure, the side of the base 21 with the tray 22 is referred to as the front side, and the opposite side is referred to 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, and the rear side of the body 11 can dock with the base 21. The base 21 and the tray 22 can dock with different positions of the cleaning device 1 respectively, thereby performing maintenance work.

[0069] In one embodiment of this disclosure, reference is made to Figure 2 A drain trough assembly 211 can be installed on the base 21. The drain trough assembly 211 can be used to connect with the wastewater tank 13, so that after the cleaning equipment 1 completes the cleaning work, the dirt collected during the cleaning process can be discharged through the drain trough assembly 211. The wastewater tank 13 is installed on the body 11, specifically, the wastewater tank 13 can be installed on the rear side of the body 11. When the cleaning equipment 1 connects with the cleaning base station 2, the drain trough assembly 211 is located below the wastewater tank 13 and communicates with the inner cavity of the wastewater tank 13. The dirt in the wastewater tank 13 can be discharged to the drain trough assembly 211 under the action of gravity, and the drain trough assembly 211 can perform subsequent discharge treatment of the dirt.

[0070] refer to Figure 2 and Figure 3The water valve assembly 23 includes a water valve unit disposed on the base station body for docking with the cleaning equipment 1. The water valve unit may have only one water valve or may include multiple water valves. In a specific embodiment of this disclosure, the water valve unit includes a first water valve 231 and a second water valve 232. In one embodiment of this disclosure, the first water valve 231 and the second water valve 232 are disposed on the tray 22, and the first water valve 231 is configured to be adjacent to the second water valve 232. The first water valve 231 and the second water valve 232 are prone to leakage of a small amount of liquid during docking, and a small amount of liquid may remain when the cleaning equipment 1 is separated from the cleaning base station 2. This liquid 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 disposed on the base 21, the above-mentioned liquid will drip onto other components at lower positions, which may have an adverse effect on the lower components. This disclosure places both the first water valve 231 and the second water valve 232 on the tray 22, so that the water at the valves can be received by the tray 22 without affecting other components. The first water valve 231 is configured to communicate with the wastewater tank 13 of the cleaning equipment 1, and the second water valve 232 is configured to communicate with the clean water tank 14 of the cleaning equipment 1. In one embodiment of this disclosure, the tray 22 may be provided with a first liquid supply line communicating with the first water valve 231 and a second liquid supply line communicating with the second water valve 232. The cleaning base station 2 includes a control unit, which is configured to control the first water valve 231 to flush and / or replenish water to the wastewater tank 13 through the first liquid supply line, and is configured to control the second water valve 232 to replenish water to the clean water tank 14 through the second liquid supply line. This enables the cleaning base station 2 to flush and / or replenish the wastewater tank 13 and replenish the clean water tank 14. Users do not need to manually remove the wastewater tank 13 for cleaning or the clean water tank 14 for replenishment, making the cleaning work easier, more convenient, and less messy, thus improving the user experience.

[0071] Furthermore, the operating parameters of the first water valve 231 and the second water valve 232 are different, and correspondingly, the flow rates of the first and second liquid supply lines are different. It is understood that the second water valve 232 can replenish the clean water tank 14 using only a smaller flow rate; while the first water valve 231 must use a larger flow rate to ensure sufficient force when flushing the wastewater tank 13. In a specific embodiment of this disclosure, the control unit is configured to control the flow rate of the first liquid supply line to be 10 L / min to 15 L / min; and / or, control the flow rate of the second liquid supply line to be 1.5 L / min to 2.5 L / min. Preferably, the flow rate of the second liquid supply line is 1.7 L / min to 2.3 L / min. Water pumps can be installed upstream of the first and second liquid supply lines, respectively, and the control unit can adjust the water flow rates of the first and second liquid supply lines by controlling parameters such as the duty cycle of the two pumps. This ensures the effectiveness of the first water valve 231 in flushing the sewage tank 13, and also ensures that the clean water tank 14 can be replenished with water within a reasonable timeframe.

[0072] In one embodiment of this disclosure, the floor brush assembly 12 is provided with a third liquid supply line communicating with the wastewater tank 13 and a fourth liquid supply line communicating with the clean water tank 14. (See reference...) Figure 15 and Figure 16 The third and fourth liquid supply lines are configured such that a first docking portion 151 and a second docking portion 152 are formed at the bottom of the floor brush assembly 12 for docking with the first water valve 231 and the second water valve 232, respectively.

[0073] Specifically, the first docking part 151 may include a first valve core. The first valve core can be set at the opening position of the third liquid supply pipeline by a first elastic device. The first elastic device keeps the first valve core in a closed state by elastic force, thereby keeping the third liquid supply pipeline in a closed state and preventing liquid in the sewage tank 13 from leaking out from the first docking part 151. When the first water valve 231 docks with the first docking part 151, the first push rod provided on the first water valve 231 can push the first valve core, thereby moving the first valve core to an open state. The third liquid supply pipeline is connected to the first water valve 231, and the cleaning base station 2 can be connected to the sewage tank 13 in sequence through the first liquid supply pipeline, the first water valve 231, the first docking part 151, and the third liquid supply pipeline, thereby flushing the sewage tank 13.

[0074] Similarly, the second docking part 152 may include a second valve core. The second valve core can be set at the opening position of the fourth liquid supply pipeline by a second elastic device. The second elastic device keeps the second valve core in a closed state by elastic force, thereby keeping the fourth liquid supply pipeline in a closed state and preventing liquid in the clean water tank 14 from leaking out from the second docking part 152. When the second water valve 232 docks with the second docking part 152, the second push rod provided on the second water valve 232 can push the second valve core, thereby moving the second valve core to an open state. The fourth liquid supply pipeline is connected to the second water valve 232, and the cleaning base station 2 can be connected to the clean water tank 14 in sequence through the second liquid supply pipeline, the second water valve 232, the second docking part 152, and the fourth liquid supply pipeline, thereby replenishing the clean water tank 14 with water.

[0075] As mentioned above, the first water valve 231 of this disclosure is configured to be adjacent to the second water valve 232, therefore the first docking portion 151 and the second docking portion 152 can also be disposed adjacent to each other. (See reference...) Figure 16 A groove 15 can be provided at the bottom of the floor brush assembly 12, and the first docking part 151 and the second docking part 152 can be arranged adjacently inside the groove 15. It is understood that without the groove 15, the first docking part 151 and the second docking part 152 would protrude from the bottom surface of the floor brush assembly 12. During the cleaning process, the first docking part 151 and the second docking part 152 would easily interfere with the working surface, leading to potential collision damage and reduced smoothness of movement of the cleaning device 1, resulting in a poor user experience. This disclosure, by providing the groove 15, prevents the first docking part 151 and the second docking part 152 from protruding from the bottom surface of the floor brush assembly 12, thereby preventing collision damage and improving the smoothness of movement of the cleaning device 1, thus enhancing the user experience.

[0076] This disclosure arranges both the first water valve 231 and the second water valve 232 on the tray 22, thus placing both valves at the lowest position of the cleaning base station 2. The cleaning device 1 can then be stably connected under its own weight. Furthermore, the water at the valves can be collected by the tray 22, preventing any impact on other components. Additionally, the proximity of the first water valve 231 and the second water valve 232 improves the integration of the water supply valve assembly 23. The floor brush assembly 12 can have only one slot 15 for connecting with the water supply valve assembly 23, eliminating the need for separate holes for connecting the first water valve 231 and the second water valve 232.

[0077] In one embodiment of this disclosure, reference is made to Figure 2 and Figure 4The 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 23 is configured to protrude above the top end face of the tray 22. Specifically, an opening may be provided on the top end face of the tray 22, and the top of the mounting base 233 may extend from the opening to be above the top end face of the tray 22. As mentioned above, the tray 22 is provided with a first liquid supply line and a second liquid supply line. In order for the first water valve 231 and the second water valve 232 to be smoothly connected to the first liquid supply line and the second liquid supply line, the mounting base 233 may extend from the top end face of the tray 22 from the inner cavity of the tray 22.

[0078] This disclosure improves the integration of the water supply valve assembly 23 by providing a mounting base 233 that integrates the first water valve 231 and the second water valve 232, making the water supply valve assembly 23 more integrated. The mounting base 233 extends from the opening on the tray 22 to protrude from the top end face of the tray 22. When the cleaning device 1 docks with the cleaning base station 2, the mounting base 233 can extend into the groove 15 on the bottom surface of the floor brush assembly 12 for docking. The mounting base 233 can have a shape adapted to the groove 15, such as an elliptical shape or a rounded rectangle shape, and this disclosure does not limit it.

[0079] Furthermore, such as Figure 4 As shown, the mounting base 233 has two adjacent mounting holes 230, 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 the same shape and size, and the first water valve 231 and the second water valve 232 can also have the same shape and size, so that the water valve assembly 23 has an aesthetically pleasing appearance and strong overall integrity. During docking, the first docking part 151 and the second docking part 152 in the groove 15 of the floor brush assembly 12 can extend into the two mounting holes 230 respectively, so as to dock with the first water valve 231 and the second water valve 232 respectively, so as to connect the water flow path between the cleaning base station 2 and the cleaning equipment 1.

[0080] In one embodiment of this disclosure, reference is made to Figure 15 The floor brush assembly 12 has a walking mechanism on its bottom surface. The walking mechanism may include two walking wheels 123 spaced apart on both sides of the bottom surface of the floor brush assembly 12, and a drive wheel 124 located between the two walking wheels 123. The drive wheel 124 can rotate under the drive of a motor, thereby providing walking power for the floor brush assembly 12. The two walking wheels 123 can play an auxiliary role in the movement of the floor brush assembly 12, thereby facilitating the cleaning device 1 to maintain balance.

[0081] Both the traveling wheel 123 and the drive wheel 124 partially protrude from the bottom surface of the floor brush assembly 12, therefore, space needs to be provided on the tray 22 to accommodate the traveling wheel 123 and the drive wheel 124 respectively. Specifically, refer to... Figure 2 and Figure 3 The tray 22 has wheel grooves 221 at both ends, and a drive wheel groove 222 is provided between the two wheel grooves 221. When the cleaning device 1 is connected to the cleaning base station 2, the wheel 123 is located in the wheel groove 221, and the drive wheel 124 is located in the drive wheel groove 124, so that the cleaning device 1 can be stably supported on the cleaning base station 2.

[0082] In one embodiment of this disclosure, such as Figure 3 As shown, the X-axis and Y-axis are defined vertically in the horizontal plane. The Y-axis direction is defined as the front-to-back direction of the base 21. The first water valve 231 and the second water valve 232 are arranged along the X-axis direction. Figure 2 As shown, the water inlet valve assembly 23 is configured to be located in the region between the central axis of the tray 22 and the outer edge of one of the wheel grooves 221; wherein the central axis of the tray 22 and the outer edge of the wheel groove 221 extend along the Y-axis direction.

[0083] Figure 2 The two dashed lines represent the central axis of tray 22 and the outer edge of one of the wheel grooves 221, respectively. The water inlet valve assembly 23 can be positioned between these two dashed lines, resulting in a more rational layout on tray 22. It is understood that... Figure 2 The layout shown only shows the water inlet valve assembly 23 located between the outer edge of the right travel wheel groove 221 and the central axis of the tray 22. The water inlet valve assembly 23 can also be located between the outer edge of the left travel wheel groove 221 and the central axis of the tray 22.

[0084] In one embodiment of this disclosure, such as Figure 2 As shown, a charging section protruding from the top end face of the tray 22 is provided on the tray 22. The charging section is configured to dock with the cleaning device 1 to charge the cleaning device 1. (Reference) 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 connected to 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 that the cleaning base station 2 can charge the cleaning device 1.

[0085] Furthermore, there can be two charging ports 125, which can be symmetrically arranged on opposite sides of the central axis of the floor brush assembly 12. Correspondingly, there can also be two charging units, which can be symmetrically arranged on opposite sides of the central axis of the tray 22.

[0086] like Figure 2 As shown, a charging contact 224 for power supply is provided on the charging unit. The lowest point of the charging contact 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 224 is a structure used to charge the cleaning device 1. It is usually made of metal. The charging contact 224 should not come into contact with liquid; otherwise, leakage or short circuit accidents may occur, causing safety hazards. The circuit of the cleaning base station 2 may also be affected, leading to a malfunction of the cleaning base station 2. This disclosure sets the lowest point of the charging contact 224 at a height higher than the first water valve 231 and the second water valve 232, thereby preventing water from flowing from the first water valve 231 and the second water valve 232 to the charging contact 224, effectively preventing leakage or short circuit accidents, and improving the safety of the cleaning base station 2.

[0087] In one embodiment of this disclosure, reference is made to Figures 3 to 12 The clean base station disclosed herein also includes a locking assembly located in the X-axis and / or Y-axis direction of the water inlet valve assembly 23. For example... Figure 3 As shown, since the water inlet valve assembly 23 has a certain length and width, it can extend on the tray 22 in the X and Y directions to form X and Y regions respectively, and the locking assembly is located in the X and / or Y regions. It should be noted that... Figure 3 The X and Y regions shown are located within the horizontal plane of the tray 22. In other application scenarios, the X and Y regions may also be located in other planes, and this disclosure does not limit this. For example, the Y region may extend to the base 21, and the locking assembly may be disposed on the base 21.

[0088] The locking component is configured to move between a locked position and an unlocked position, specifically, Figures 5 to 8 The structure of the locking assembly in the locking position is shown: when in the locking position, the locking assembly is configured to lock the cleaning device 1 onto the base station body; Figures 9 to 12 The structure of the locking assembly in the unlocked position is shown: when in the unlocked position, the locking assembly is configured to unlock the cleaning device 1 from the base station body.

[0089] It should be noted that, in one embodiment of this disclosure, the locking component can be disposed on the cleaning base station 2 or on the cleaning device 1. When the locking component is disposed on the cleaning base station 2, the locking component can move relative to the base station body between a locked position and an unlocked position; when in the locked position, the locking component can cooperate with the cleaning device 1 to lock the cleaning device 1 onto the base station body; when in the unlocked position, the locking component can separate from the cleaning device 1, thereby unlocking the cleaning device 1 from the base station body. When the locking component is disposed on the cleaning device 1, the locking component can move relative to the cleaning device 1 between a locked position and an unlocked position; when in the locked position, the locking component can cooperate with the cleaning base station 2 to lock the cleaning device 1 onto the base station body; when in the unlocked position, the locking component can separate from the cleaning base station 2, thereby unlocking the cleaning device 1 from the base station body. The following description will use the example of the locking component being disposed on the cleaning base station 2.

[0090] This disclosure improves the stability of the connection between the cleaning device 1 and the cleaning base station 2 by incorporating a locking component. Specifically, the locking component securely locks the cleaning device 1 to the base station body, preventing the water pressure from the cleaning base station 2 when supplying water to the cleaning device 1 from lifting it, thereby preventing water leakage. Furthermore, the instability in the connection 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 inlet valve assembly 23. By positioning the locking component along the X-axis and / or Y-axis of the water inlet valve assembly 23, the position of the locked cleaning device 1 is directly related to the water inlet valve assembly 23, which helps to balance the water pressure impact during water supply and most effectively ensures stable connection at the water inlet valve assembly 23, further improving the overall connection stability.

[0091] In one embodiment of this disclosure, at least two locking components are provided, arranged in the X-axis direction and located on both sides of the water inlet valve assembly 23; and / or, at least two locking components are arranged in the Y-axis direction and located on both sides of the water inlet valve assembly 23. (See reference...) Figure 3 In the view direction, when there are two locking components, the two locking components can be set on the left and right sides or the top and bottom sides of the water inlet valve component 23 respectively. The distance between the two locking components and the water inlet valve component 23 can be equal. The two locking components can lock the cleaning device 1 onto the cleaning base station 2 together, thereby balancing the water pressure impact during water supply, avoiding uneven force on one side of the cleaning device 1, and improving the docking stability of the cleaning device 1.

[0092] When there are two or more locking components, the multiple locking components may not be evenly distributed on both sides of the water inlet valve assembly 23 in the X-axis direction and / or y-axis direction. In this case, the force of each locking component can be calculated separately, and the multiple locking components can be arranged reasonably to make the locking components on both sides of the water inlet valve assembly 23 have a balanced force, thereby balancing the water pressure impact during water supply and improving the docking stability of the cleaning equipment 1.

[0093] In another embodiment of this disclosure, a single locking component is provided, configured to be located adjacent to the water inlet valve assembly 23, thereby facilitating the balancing of the water pressure impact force at the water inlet valve assembly 23. When the locking component is located adjacent to the water inlet valve assembly 23, multiple locking components are not required; only one locking component is needed to stably lock the cleaning device 1 onto the cleaning base station 2.

[0094] In a preferred embodiment of this disclosure, a locking assembly is configured to be disposed between the first water valve 231 and the second water valve 232, thereby balancing the water pressure impact between the two water valves using only one locking assembly. Whether the first water valve 231 is flushing the wastewater tank 13, the second water valve 232 is replenishing the clean water tank 14, or both water valves are working together, the locking assembly disposed between the first water valve 231 and the second water valve 232 can balance the water pressure impact, improving the stability of the connection of the cleaning equipment 1.

[0095] In another embodiment of this disclosure, the locking assembly is configured to be mounted on the mounting base 233. As mentioned above, the water inlet valve assembly 23 is mounted on the tray 22 and is used to cooperate with the floor brush assembly 12 of the cleaning device 1. The locking assembly is configured to lock the floor brush assembly 12. The locking assembly mounted on the mounting base 233 is movable relative to the mounting base 233 between a locked position and an unlocked position. Specifically, when moved to the locked position, the locking assembly can cooperate with the floor brush assembly 12 to lock the floor brush assembly 12 onto the tray 22; when moved to the unlocked position, the locking assembly can disengage from the floor brush assembly 12.

[0096] It should be noted that mounting the locking assembly on the mounting base 233 is the most preferred embodiment of this disclosure. The mounting base 233 is part of the water inlet valve assembly 23, and directly mounting the locking assembly on the water inlet valve assembly 23 can best balance the water pressure impact and achieve the best locking effect. The water pressure when the cleaning base station 2 supplies water to the cleaning equipment 1 will not lift the floor brush assembly 12, thus minimizing the occurrence of water leakage.

[0097] In one embodiment of this disclosure, reference is made to Figures 4 to 13The locking assembly includes a drive mechanism and a locking mechanism 241. The locking mechanism 241 is configured to be located in the X-axis and / or Y-axis direction of the water inlet valve assembly 23 and movable relative to the mounting base 233, and is configured to move between a locked position and an unlocked position under the action of the drive mechanism. Figure 13 As shown, the locking mechanism 241 has a locking end for engaging with the floor brush assembly 12, and a driving end opposite to the locking end, which can be used for transmission connection with a drive mechanism. The locking end can be configured as a hook 2410, which, when in the locked position, locks the floor brush assembly 12 onto the tray 22; when in the unlocked position, the hook 2410 can disengage from the floor brush assembly 12.

[0098] Specifically, refer to Figure 4 , Figure 8 and Figure 12 The mounting base 233 is provided with an opening 2331. Specifically, the opening 2331 can be formed on the side wall of the mounting base 233 in the X-axis direction, that is, the opening 2331 is located on the side wall of the mounting base 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 extend at least partially from the opening 2331 to lock with the cleaning device 1; as Figure 12 As shown, when in the unlocked position, the locking end of the latching mechanism 241 is configured to retract from the opening 2331 into the cavity of the mounting base 233 to disengage from the cleaning device 1.

[0099] When the latch 2410 of the locking mechanism 241 moves to the locked position, it can extend outward from the side wall of the mounting base 233 in the X-axis direction to engage with the floor brush assembly 12. Figure 16 As shown, a locking groove 153 is provided on the side wall of the slot 15. The hook 2410, located in the locking position, can extend into the locking groove 153 to lock the floor brush assembly 12 onto the tray 22. Figure 12 As shown, when the locking mechanism 241 is in the unlocked position, the hook 2410 can disengage from the locking 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 valve assembly 23, and the user can easily remove the cleaning device 1 from the cleaning base station 2.

[0100] In one embodiment of this disclosure, such as Figure 13As shown, the locking mechanism 241 can be mounted on a component within the cavity of the tray 22 and extends into the interior of the mounting base 233, such that when the locking mechanism 241 is in the locked position, its locking end at least partially protrudes from the opening 2331. In one specific embodiment, the locking mechanism 241 can also be directly mounted on the mounting base 233. The locking mechanism 241 includes a pivot 2411, which can be positioned at the center of the locking mechanism 241, specifically at a position slightly above the center, see reference. Figure 13 In the view, the locking end hook 2410 of the locking mechanism 241 is located above the rotating shaft 2411, and the driving end of the locking mechanism 241 is located below the rotating shaft 2411. The locking mechanism 241 can be hinged to the mounting base 233 via the rotating shaft 2411, or to other components in the inner cavity of the tray 22.

[0101] refer 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 connected to the driving end of the locking mechanism 241 and is configured to drive the locking mechanism 241 to move between a locked position and an unlocked position around its rotation axis 2411. The movable part can be a rod-shaped movable shaft, and a flange 2421 can be provided on the end of the movable part near the locking mechanism 241. A waist-shaped hole 2412 is provided on the driving end of the locking 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 at the same time drive the locking mechanism 241 to rotate around the rotation axis 2411 to move between the locked position and the unlocked position.

[0102] refer to Figure 7 In the viewing direction, when the movable part moves away from the direction of the locking mechanism 241, that is, moves to the left, the flange 2421 can slide downward along the oblong hole 2412. The drive end of the locking mechanism 241 moves to the left, thereby causing the locking mechanism 241 to rotate clockwise around the pivot 2411, which in turn causes the hook 2410 to move outside the opening 2331 of the mounting base 233, thereby moving the locking mechanism 241 to the locked position.

[0103] refer to Figure 11 In the view direction, when the movable part moves toward the direction of the locking mechanism 241, that is, moves to the right, the flange 2421 can slide upward along the oblong hole 2412. The drive end of the locking mechanism 241 moves to the right, thereby causing the locking mechanism 241 to rotate counterclockwise around the pivot 2411, which in turn causes the hook 2410 to move into the opening 2331 of the mounting base 233, thereby moving the locking mechanism 241 to the unlocked position.

[0104] In one embodiment of this disclosure, such as Figure 14As shown, when in the locked position, the line connecting the force-bearing position of the locking end acting on the cleaning device 1 and the rotation center of the rotating shaft 2411 is configured to be perpendicular to the motion axis of the movable part. When the hook 2410 engages in the engaging groove 153, the contact position between the two is... Figure 14 The force application points are marked in the diagram, and the line connecting these force application points to the rotation center of shaft 2411 is shown in the diagram. Figure 14 As shown by the dotted line in the diagram. This line is perpendicular to the axis of motion of the movable part, which allows the locking mechanism 241 to bear almost all the locking force when locking the floor brush assembly 12, so that the drive mechanism is basically not subjected to force. Moreover, this structural design can also increase the upper limit of the locking force of the hook 2410.

[0105] In one embodiment of this disclosure, reference is made to Figure 7 and Figure 11 The fixed part is an electromagnet 243, and the movable part is an iron core 242. Specifically, the electromagnet 243 has an inner cavity, and the iron core 242 is located within the inner cavity of the electromagnet 243. The electromagnet 243 is configured to, when energized, drive the iron core 242 to move the locking mechanism 241 from the unlocked position to the locked position. (Reference) Figure 7 In the view, when energized, the iron core 242 inside the electromagnet 243 experiences a force to the left under electromagnetic induction. The iron core 242 moves to the left, causing the locking mechanism 241 to rotate, thus causing the locking mechanism 241 to... Figure 11 The locking position shown moves to Figure 7 The locking position is shown. In this embodiment, electromagnetic force is used to drive the locking mechanism 241, so various conventional electronic control methods can be used to control the locking, such as controlling the circuit through buttons, remote control, etc. When energized, the locking mechanism 241 can be driven to move to the locking position.

[0106] Further reference Figure 7 and Figure 11 The drive mechanism also includes a first elastic element 244 pre-compressed between the iron core 242 and the electromagnet 243. The first elastic element 244 can be a spring. When the electromagnet 243 is energized, 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 element 244. When the electromagnet 243 is de-energized, the iron core 242 is no longer subject to electromagnetic force, and the iron core 242 is configured to drive the locking mechanism 241 from the locked position to the unlocked position under the elastic force of the first elastic element 244.

[0107] In existing technology, in the event of a power outage, cleaning device 1 may become locked to cleaning base station 2 and cannot be removed. This is because existing technology typically uses an electromechanical locking mechanism to lock cleaning device 1 to cleaning base station 2. The locking and unlocking of this type of mechanism requires electrical drive and does not possess the characteristic of an electromagnet 243 where the force disappears after a power outage. In the event of an unexpected power outage, the locking mechanism cannot move and will remain in the locked position, thus causing cleaning device 1 to become locked to cleaning base station 2 and unable to be removed.

[0108] This embodiment uses an electromagnet 243 to drive the iron core 24, thereby moving the locking mechanism 241 between the locked and unlocked positions. In the event of an accidental power outage, the electromagnet 243 is de-energized, and the electromagnetic force on the iron core 24 disappears. At this time, the compressed and stored elastic force of the first elastic element 244 is released, allowing the iron core 24 to smoothly return to its original position under the action of the elastic force, thus unlocking the locking mechanism 241. This disclosure achieves an automatic reset function in the event of a power outage, avoiding the problem of the cleaning device 1 being locked on the cleaning base station 2 and unable to be removed due to a power outage.

[0109] It should be noted that the locking mechanism 241 does not need to continuously lock the brush assembly 12, but only needs to lock it when the water inlet valve assembly 23 is in operation. If the locking mechanism 241 continuously locks the brush assembly 12, the electromagnet 243 will be energized for a long time, which will cause the electromagnet 243 to overheat. To prevent the electromagnet 243 from overheating, the energization time at one time should not be too long, and it is sufficient to lock it only when the water inlet valve assembly 23 is working. At other times when the water inlet valve assembly 23 is not working, the cleaning device 1 will not be subjected to 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.

[0110] In one embodiment of this disclosure, reference continues to be made to... Figure 7 and Figure 11 The cleaning base station 2 also includes a trigger 245, which can be, for example, a detection mechanism of a micro switch. The trigger 245 is configured to be activated when the iron core 242 or the locking mechanism 241 moves to a locked position and / or an unlocked position. In one specific embodiment of this disclosure, the trigger 245 may be located on the iron core 242 away from the locking mechanism 241, such as... Figure 7 As shown, when the locking mechanism 241 is in the locked position, the trigger 245 can contact the iron core 242, and thus be triggered by the iron core 242; as Figure 11As shown, when the locking mechanism 241 is in the unlocked position, the trigger 245 can separate from the iron core 242. A heat-insulating silicone rubber 246 can be provided at the end of the iron core 242 near the trigger 245. During operation, the iron core 242 generates heat, and the heat-insulating silicone rubber 246 can isolate this heat from the trigger 245, thereby extending the lifespan of the trigger 245.

[0111] The trigger 245 can also have other settings. For example, it can be set in a position that can be directly triggered by the locking mechanism 241 instead of being triggered by the iron core 242. Alternatively, the trigger 245 can be configured to be triggered when the locking mechanism 241 is in the unlocked position. This disclosure does not limit the specific triggering method of the trigger 245.

[0112] The cleaning base station 2 also includes a control unit configured to control water supply based on an electrical signal from the trigger 245. When water supply is required, the control unit energizes the electromagnet 243, causing the locking mechanism 241 to move to the locked position. At this time, the trigger 245 is activated. The activation of the trigger 245 indicates that the cleaning device 1 is securely locked onto the cleaning base station 2, and water supply can begin. The control unit can control the water pump inside the cleaning base station 2 to supply water. By setting the trigger 245, it is ensured that water supply begins only after locking. Otherwise, water supply might begin before locking, and the water pressure would impact the cleaning device 1, causing instability. In an unstable state, water leakage may occur, and the latch 2410 may have difficulty aligning with the locking slot 153, making locking difficult.

[0113] Furthermore, when the trigger 245 is activated, it means that the locking mechanism 241 is in the locked position. The control unit can determine the current state of the locking mechanism based on the electrical signal, and thus can issue other control information. The control information can be information reminding the user of the current state, for example, it can be displayed on the screen, or it can be reminded by an indicator light.

[0114] In another embodiment of this disclosure, the locking mechanism 241 may also be electrically driven, but rather movably mounted on the mounting base 233 via a fully mechanical connection. This fully mechanical connection also prevents the cleaning device 1 from locking onto the cleaning base station 2 and becoming unusable due to an unexpected power outage. Specifically, the locking mechanism 241 is configured to be pre-pressed onto the mounting base 233 by a second elastic member and is configured to remain in the locked position under the elastic force of the second elastic member. The locking mechanism 241 can remain in the locked position under the elastic force when no external force is applied, and regardless of whether the cleaning device 1 is on the cleaning base station 2, the hook 2410 on the locking mechanism 241 will always be exposed outside the mounting base 233 as long as no external force is applied.

[0115] When the cleaning device 1 is docked, the locking mechanism 241 is configured 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 is performed, 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 base 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 pop out from the opening 2331 of the mounting base 233 under the action of elasticity, thereby extending into the engagement groove 153 of the floor brush assembly 12 to lock the floor brush assembly 12 onto the tray 22.

[0116] In this embodiment, the driving mechanism is a mechanical button located on the side wall or top of the base station body. For example, it could be a button located on the top of the base 21, or a kick block located on the side wall of the cleaning base station 2. The mechanical button is configured to drive the locking mechanism 241 to the unlocked position when subjected to external force. The mechanical button and the locking mechanism 241 are connected together. 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 it can return to the locked position under the elastic force of the second elastic element.

[0117] refer to Figures 17 to 23The clean water tank 14 of this disclosure is disposed 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. The floor brush housing 120 is used to support various components of the floor brush assembly 12. The roller brush cover 122 is configured to be detachably connected to the floor brush housing 120 according to a preset assembly / disassembly path, and is configured to form a roller brush cavity with the floor brush housing 120. The roller brush 121 is located inside the roller brush cavity and is configured to be rotatably connected to the floor brush housing 120. The roller brush cavity formed by the roller brush cover 122 and the floor brush housing 120 can have a shape adapted to the roller brush 121. The roller brush 121 extends from the lower opening of the roller brush cavity to contact the working surface. The roller brush cavity can provide protection for the roller brush 121 and prevent dirt from being thrown out when the roller brush 121 rotates.

[0118] 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 protrudes from the bottom surface of the floor brush assembly 12, therefore, a space needs to be provided on the tray 22 to accommodate the roller brush 121. Specifically, refer to... Figure 2 The tray 22 is provided with a roller brush groove 223. When the cleaning device 1 is connected to 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.

[0119] In one embodiment of this disclosure, in order to assemble and disassemble the roller brush cover 122, as follows: Figure 21 As shown, arc-shaped buckles 1222 can be respectively provided on both sides of the roller brush cover 122, and two guide grooves adapted to the arc-shaped buckles 1222 can be provided on the brush housing 120. The arc-shaped buckles 1222 can be set on the roller brush cover 122 by an elastic device. Under the action of the elastic device, the arc-shaped buckles 1222 are kept in the position extending out of the end of the roller brush cover 122; and when the arc-shaped buckles 1222 are subjected to external force, they overcome the elastic force and retract into the roller brush cover 122. In the absence of external force, the arc-shaped buckles 1222 will always be kept in the guide groove under the elastic force of the elastic device; only when the elastic device is compressed by external force can the arc-shaped buckles 1222 retract into the roller brush cover 122, thereby disengaging from the guide groove. To facilitate the disassembly and assembly of the roller brush cover 122, such as Figure 21 As shown, a handle 1221 can be provided on the roller brush cover 122. The user can move the arc-shaped buckle 1222 by using the handle 1221 to remove and install the roller brush cover 122.

[0120] Continue to refer to Figure 21Two handles 1221 are provided on the roller brush cover 122. These handles 1221 are configured to move relative to the roller brush cover 122 in a direction that is either facing each other or away from each other. When subjected to external force, each handle 1221 compresses its corresponding elastic device. When it is necessary to remove the roller brush cover 122 from the floor brush housing 120, the user can pinch the two handles 1221 and apply force towards each other. The two handles 1221 compress their respective elastic devices, causing their corresponding arc-shaped latches 1222 to move out of the guide groove. At this point, the user only needs to lift the handles 1221 upwards to remove the roller brush cover 122 from the floor brush housing 120. It is understood that the removal and installation path of the roller brush cover 122 can be vertical or at an angle to the vertical.

[0121] refer to Figures 17 to 20 The water tank 14 of this disclosure is detachably connected to the floor brush housing 120. The water tank 14 has a liquid storage chamber 140, which can be used to store clean water, cleaning solution, 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 detachable cover 1451 is provided on the water inlet. Specifically, the cover 1451 can be a rotating cover. The user can manually remove the clean water tank 14 from the ground brush housing 120 and unscrew the cover 1451 from the bottom surface of the clean water tank 14, so that water can be added to the liquid storage chamber 140 through the water inlet. After the water is added, 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 add water to the clean water tank 14. However, in the event of a failure of the automatic water addition function or if the user wants to add water manually, the manual water addition function can be easily achieved through the cover 1451 on the clean water tank 14.

[0122] refer to Figure 19 and Figure 20 The floor brush housing 120 is provided with a first pipe connector 1201, and the clean water tank 14 is provided with a second pipe connector 145 for connecting with the first pipe connector 1201. When the clean water tank 14 is installed on the floor brush housing 210, the first pipe connector 1201 can connect with the second pipe connector 145, so that the liquid in the liquid storage chamber 140 can flow into the floor brush assembly 12 through the second pipe connector 145 and the first pipe connector 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 connector 1201, and the second pipe connector 145, thereby realizing that the cleaning base station 2 automatically replenishes water to the clean water tank 14.

[0123] The second pipe connector 145 is configured to be located on the cover 1451, thus ensuring a single water injection path. This reduces the number of open connectors on the clean water tank 14, thereby reducing the structural complexity of the clean water tank 14 and minimizing water-collecting corners inside the tank. Furthermore, this disclosure places the water inlet on the bottom surface of the clean water tank 14, meaning that both the cover 1451 and the second pipe connector 145 are located on the bottom surface of the tank. This ensures that the upper surface of the clean water tank 14 is smooth and flat, maintaining visual continuity.

[0124] The liquid storage chamber 140 is configured to extend from a position corresponding to the brush housing 120 to the disassembly / removal path of the roller brush cover 122. When the disassembly / removal path of the roller brush cover 122 is vertical, the liquid storage chamber 140 can extend directly above the roller brush cover 122; when the disassembly / removal path of the roller brush cover 122 is at an angle to the vertical direction, the liquid storage chamber 140 can extend diagonally above the roller brush cover 122. When the clean water tank 14 is installed on the brush housing 120, the liquid storage chamber 140 will block the disassembly / removal path of the roller brush cover 122, making it impossible to disassemble or assemble the roller brush cover 122; the roller brush cover 122 can only be disassembled or assembled after the clean water tank 14 has been removed from the brush housing 120.

[0125] This disclosure reduces the weight of the unit 11 by placing the water tank 14 on the brush housing 120, making it easier for the user to push the cleaning device 1. Furthermore, the water tank 14 on the brush housing 120 increases the downward pressure on the brush assembly 12, thereby improving the cleaning effect of the roller brush 121 on the work surface. The water storage chamber 140 of the water tank 14 extends to a position located on the disassembly path of the roller brush cover 122, allowing the water tank 14 to be integrated simultaneously with the roller brush cover 122 onto the brush assembly 12. The outwardly extending storage chamber 140 also increases the capacity of the water tank 14, providing enough water for a full house cleaning without the need for repeated refills, thus improving the user experience.

[0126] In one embodiment of this disclosure, the side of the cleaning device 1 facing the user in the cleaning work surface state is referred to as the rear side, and the opposite side is referred to as the front side. The roller brush cover 122 is configured to be located on the front side of the floor brush housing 120, and the liquid storage chamber 140 is configured to extend forward to the disassembly and assembly path of the roller brush cover 122. It is understood that the user usually stands behind the cleaning device 1 and pushes and pulls the body 11 back and forth using the handheld part 10 to achieve cleaning. 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 chamber 140, the liquid storage chamber 140 of this disclosure extends forward to the disassembly and assembly path of the roller brush cover 122.

[0127] Specifically, the liquid storage chamber 140 is installed on the top of the brush housing 120 and is configured to extend forward above the roller brush cover 122, such that the orthographic projections of the liquid storage chamber 140 and the roller brush cover 122 on their working surfaces at least partially overlap. In this embodiment, the roller brush cover 122 can be installed and removed vertically upwards, and the liquid storage chamber 140 extending above the roller brush cover 122 has a large capacity, thereby reducing the number of times the user needs to return to the cleaning base station 2 to refill water.

[0128] Furthermore, in one embodiment of this disclosure, the top end face of the clean water tank 14 is configured to form at least a portion of the top end face of the floor brush assembly 12. The clean water tank 14, mounted above the roller brush cover 122, has an upwardly extending space. Since the top end face of the clean water tank 14 can serve as at least a portion of the top of the floor brush assembly 12, it is evident that at least a portion of the clean water tank 14 is not obstructed by other components. Therefore, the clean water tank 14 can extend appropriately upwards, thereby further increasing the capacity of the liquid storage chamber 140.

[0129] Preferably, the roller brush cover 122 is configured to have a top, and the liquid reservoir 140 is configured to extend to cover the top of the roller brush cover 122. In this case, the liquid reservoir 140 can cover at least a portion of the upper surface of the roller brush cover 122, and the top end face of the clean water tank 14 participates in forming most or all of the upper surface of the floor brush assembly 12, thereby maximizing the projected area of ​​the clean water tank 14 on the working surface and thus maximizing the capacity of the liquid reservoir 140.

[0130] To maximize the capacity of the liquid storage chamber 140 while keeping the height of the water tank 14 constant, the projected area of ​​the water tank 14 on the working surface needs to be maximized. In one specific embodiment of this disclosure, the liquid storage chamber 140 is configured to cover the top end face of the floor brush housing 120. In this case, the liquid storage chamber 140 can completely cover the upper surface of the roller brush cover 122, and the top end face of the water tank 14 surrounds the entire upper surface of the floor brush assembly 12, thereby maximizing the capacity of the liquid storage chamber 140.

[0131] In one embodiment of this disclosure, the roller brush cover 122 also includes a front sidewall extending obliquely downward from its top front side. The front sidewall of the roller brush cover 122 and the front sidewall of the clean water tank 14 are configured to form the front sidewall of the floor brush assembly 12. Specifically, the front sidewall of the clean water tank 14 and the front sidewall of the roller brush cover 122 together constitute the front sidewall of the floor brush assembly 12. For example... Figure 17 As shown, the front sidewall of the roller brush cover 122 is located further forward than the front sidewall of the clean water tank 14. During the cleaning process, the front end of the floor brush assembly 12 may collide with obstacles, and the front sidewall of the roller brush cover 122 can protect the clean water tank 14 from direct frontal collision.

[0132] In one embodiment of this disclosure, reference is made to Figures 18 to 20 An upwardly extending adapter 126 is provided on the rear side of the floor brush housing 120, and the main body 11 is configured to be movably connected to the adapter 126. The adapter 126 allows the floor brush assembly 12 to rotate flexibly relative to the main body 11, facilitating turning during cleaning.

[0133] Understandably, the entire upper portion of the adapter 126 is used for connecting the main body 11, and the clean water tank 14 cannot extend to the upper portion of the adapter 126. For example... Figure 20 As shown, the liquid storage chamber 140 is provided with a first clearance part 141 to avoid the adapter part 126 at the position corresponding to the adapter part 126. The position of the first clearance part 141 is used to accommodate the body 11. The first clearance part 141 can be located in the middle 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 clearance part 141, the adapter part 126 on the floor brush housing 120 is avoided, and the clean water tank 14 provides installation space for the adapter part 126, thereby allowing the body 11 to be connected to the floor brush assembly 12.

[0134] In one embodiment of this disclosure, such as Figure 20 As shown, a positioning part 146 can be provided on the clean water tank 14. The positioning part 146 can be a protruding structure provided on the rear side wall of the clean water tank 14, thereby forming a positioning part 146 located within the first clearance part 141. Figure 18 As shown, a positioning groove 1203 adapted to the positioning part 146 can be provided on the floor brush housing 120. The positioning groove 1203 can be formed on the front side wall of the adapter part 126. When installing the clean water tank 14, the user can quickly determine the installation position through the positioning part 146 and the positioning groove 1203. The positioning part 146 can form a guiding fit with the positioning groove 1203, thereby reducing the installation difficulty of the clean water tank 14 and improving the user experience.

[0135] In one embodiment of this disclosure, reference continues to be made to... Figures 18 to 20The top end face of the roller brush cover 122 is constructed to be higher than the top end face of the floor brush housing 120. By adjusting the layout of the components inside the floor brush housing 120, the height 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 compensate for the water tank 14 located above the floor brush housing 120, thereby further expanding the capacity of the water tank 14. The water tank 14 is provided with a second clearance part 142 corresponding to the position of the roller brush cover 122 to avoid the roller brush cover 122. The second clearance part 142 can be provided on the front bottom surface of the water tank 14. Since the upper surface of the roller brush cover 122 has an arc shape that matches the roller brush 121, the second clearance part 142 can also be set as an arc groove, or it can also be set as a sloping groove. When the clean water tank 14 is installed on the floor brush housing 120, the roller brush cover 122 is located in the second clearance part 142 and will not squeeze the bottom surface of the clean water tank 14. By setting the second clearance part 142, clearance is achieved for the roller brush cover 122, and the clean water tank 14 reserves installation space for the roller brush cover 122, thereby making the layout between the various structures of the floor brush assembly 12 reasonable.

[0136] In one embodiment of this disclosure, in order to monitor the water volume in the storage chamber 140, a level float can be installed in the storage chamber 140. The level float is mainly used to detect when the water is full, so as to provide a full water signal when the cleaning base station 2 automatically replenishes water to the clean water tank 14, so as to control the cleaning base station 2 to stop replenishing water in a timely manner. Figure 20 As shown, a protrusion 147 protruding from the bottom surface of the clear water tank 14 is provided, and the liquid level float is constructed to be located on the extension path of the protrusion 147, thereby allowing the liquid level float to be accommodated in the liquid storage cavity 140 at the corresponding position of the protrusion 147. Figure 19 As shown, a mating groove 1204 adapted to the protrusion 147 can be provided on the floor brush housing 120. When the clean water tank 14 is installed on the floor brush housing 120, the protrusion 147 is located in the mating groove 1204.

[0137] Since the overall shape of the clean water tank 14 is a flat shape with a large horizontal cross-sectional area and a low height, the level float needs to ensure a certain stroke in order to ensure the accuracy of detection. Therefore, the protrusion 147 is set to protrude from the bottom surface of the clean water tank 14 to extend the movement path of the level float. Also, 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 clean water tank 14 above the floor brush housing 120 has a greater thickness. Therefore, the protrusion 147 is set at the bottom surface position corresponding to the floor brush housing 120 of the clean water tank 14, so as not to affect the upper part of the clean water tank 14. This provides a reasonable structural layout of the clean water tank 14.

[0138] In one embodiment of this disclosure, such as Figure 20As shown, a locking assembly 143 is provided on the clean water tank 14, and the clean water tank 14 is configured to be detachably connected to the floor brush housing 120 via the locking assembly 143. Two sets of locking assemblies 143 can be provided, with the two sets of locking assemblies 143 respectively located on both sides of the clean water tank 14.

[0139] refer to Figure 18 and Figure 19 The inner walls on both sides of the floor brush housing 120 may be provided with first mating parts 1202 that cooperate with the locking assembly 143, such as... Figure 20 As shown, the locking assembly 143 may include an unlocking member 1431 and a second mating member 1432. When the water tank 14 is installed on the brush housing 120, the first mating member 1202 and the second mating member 1432 can lock together, thereby fixing the water tank 14 to the brush housing. At this time, the unlocking member 1431 is exposed on the outer wall of the water tank 14. When it is necessary to remove the water tank 14, the user can press the unlocking members 1431 on both sides of the water tank 14 simultaneously with both hands. The two unlocking members 1431 respectively push the two second mating members 1432 to the 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 brush housing 120.

[0140] This disclosure includes a locking assembly 143, enabling easy disassembly and assembly of the clean water tank 14. If only one locking assembly 143 were provided, obstacles might collide with it during cleaning, causing the clean water tank 14 to lose its fixation and fall off. This disclosure, by providing two locking assemblies 143, requires the user to use both hands to remove the clean water tank 14, effectively preventing accidental contact and improving the stability of the clean water tank 14.

[0141] When the roller brush 121 rotates in the roller brush cavity, the dirt adsorbed on its surface is thrown to the inner wall of the roller brush cover 122 under the action of centrifugal force, causing the dirt to adhere to the inner wall of the roller brush cover 122. Over time, this can easily lead to bacterial growth and odor. In one embodiment of this disclosure, refer to... 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 between the roller brush cover 122 and the clean water tank 14 for the roller brush cover 122 to move, and the movement space ensures that the roller brush cover 122 will not squeeze the clean water tank 14 during the movement.

[0142] When in the first position, such as Figure 22 As shown, the roller brush cover 122 and the roller brush 121 have a first contact area; when in the second position, as... Figure 23As shown, the roller brush cover 122 and the roller brush 121 have a second contact area; wherein, the first contact area is greater than or equal to zero, and the first contact area is less than the second contact area. A roller brush cover drive member 128 is provided in the floor brush assembly 12, which can drive the roller brush cover 122 to move between a first position and a second position.

[0143] When the first contact area is zero, the inner wall of the brush cover 122 is configured to detach from the brush 121. This prevents the brush cover 122 from interfering with the rotation and cleaning operation of the brush 121 during normal cleaning or self-cleaning. When the first contact area is greater than zero, the inner wall of the brush cover 122 partially contacts the brush 121. For example, the rear edge of the brush cover 122 may make line contact with the brush 121, or a small portion of the rear end of the brush cover 122 may be in close contact with the brush 121. The specific size of the first contact area depends on the shape of the brush cover 122 and the fluffiness of the brush 121. A brand new brush 121 will have fluffier bristles, resulting in a larger first contact area; after a period of use, the bristles of the brush 121 will become less fluffy, the diameter of the brush 121 will decrease, and the first contact area will also decrease.

[0144] 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 and the roller brush 121 are in almost complete contact. When the roller brush 121 rotates, it rubs against 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. This achieves cleaning of the inner wall of the roller brush cover 122 by the roller brush 121, avoiding manual cleaning by the user and preventing dirt residue from remaining on the inner wall of the roller brush cover 122. To ensure that the inner wall of the roller brush cover 122 is thoroughly cleaned, 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. Ideally, the inner wall of the roller brush cover 122 and the roller brush 121 are in complete contact, and the second contact area is 100% of the area of ​​the inner wall of the roller brush cover 122.

[0145] This disclosure allows the roller brush cover 122 to operate in a first position or a second position relative to the floor brush housing 120. When in the second position, the inner wall of the roller brush cover 122 contacts and engages with the roller brush 121, thereby enabling the roller brush 121 to clean the inner wall of the roller brush cover 122. This improves the automation of the cleaning equipment and eliminates the need for manual cleaning of the inner wall of the roller brush cover, thus optimizing the user experience.

[0146] Furthermore, the roller brush cover 122 can move between the first and second positions along an arc-shaped motion trajectory. As mentioned above, arc-shaped buckles 1222 are respectively provided on both sides of the roller brush cover 122, and two guide grooves adapted to the arc-shaped buckles 1222 can be provided on the brush housing 120. The two arc-shaped buckles 1222 can move within the guide grooves along the arc-shaped motion trajectory. The arc-shaped motion trajectory is beneficial for the inner wall of the roller brush cover 122 to fit together with the roller brush 121, because the roller brush 121 is a rolling body with a cylindrical or cylindrical circumferential surface. The arc-shaped motion trajectory ensures that the inner wall of the roller brush cover 122 fits together with the outer circumferential surface of the roller brush 121 as much as possible, thereby cleaning the entire inner wall of the roller brush cover 122 as thoroughly as possible, especially cleaning the inner wall that is prone to dirt accumulation.

[0147] In one embodiment of this disclosure, the liquid in the clean water tank 14 can provide clean water or cleaning fluid to the roller brush 121 for cleaning. (See reference...) Figure 22 The floor brush assembly 12 is provided with a drainage section 127, which extends in the direction of the roller brush 121, so that the liquid in the clean water tank 14 can flow to the roller brush 121 through the drainage section 127 to wet the roller brush 121.

[0148] refer to Figure 21 The roller brush cover 122 is provided with an extension 1223, which is configured to extend downward to a position adjacent to the guide section 127, and together with the guide section 127, forms a liquid outlet. After the liquid flows out of the clean water tank 14, it is guided by the guide section 127 to the liquid outlet, and then flows out of the liquid outlet to the roller brush 121. Specifically, the roller brush cover 122 is provided with an extension 1223 extending in the direction of the guide section 127 at a position corresponding to the guide section 127. The extension 1223 is located above the guide section 127 and has a predetermined distance from the guide section 127, and the two form a liquid outlet. This allows the liquid flowing out of the clean water tank 14 to flow along the guide section 127 and finally flow out through the liquid outlet to the surface of the roller brush 121. This disclosure forms an outlet between the extension 1223 and the drainage section 127. By controlling the size and position of the outlet, it is possible to prevent the roller brush 121 from throwing dirt onto the clean water tank 14 and the drainage section 127 during rotation, thus avoiding problems such as blockage.

[0149] This disclosure also provides a control method for a cleaning system, which can be applied to the cleaning system described above, or to a cleaning system including the cleaning base station 2 and the cleaning equipment 1 described above. (Reference) Figure 24The control unit can send water supply operation commands. The water supply operation is the operation in which the cleaning base station 2 supplies water to the cleaning equipment 1 through the water supply valve assembly 23. Specifically, it can include: injecting cleaning fluid into the clean water tank 14, injecting clean water into the clean water tank 14, injecting clean water into the wastewater tank 13, and rinsing the wastewater tank 13. Since the water pressure impact will cause an impact on the cleaning equipment 1 during the water supply operation, it is necessary to lock the cleaning equipment 1 to the cleaning base station 2 through the locking assembly before starting the water supply.

[0150] Specifically, the control methods for the cleaning system include:

[0151] Locking Step: The locking assembly moves to the locking position based on a first signal. This first signal is a water supply signal, which can be a signal to inject cleaning fluid into the clean water tank 14, a signal to inject clean water into the clean water tank 14, a signal to inject clean water into the wastewater tank 13, or a signal to flush the wastewater tank 13, etc. Based on the water supply signal, an energizing signal is sent to the electromagnet 243. After being energized, the electromagnet 243 drives the locking mechanism 241 to move to the locking position.

[0152] In one embodiment of this disclosure, such as Figure 24 As shown, the locking step also includes a detection step to check whether the locking assembly is fully engaged. Specifically, the engagement of the locking assembly can be detected by, for example, a trigger 245 of a micro switch: when fully engaged, the latching mechanism 241 is in the engaged position, and the trigger 245 can contact the iron core 242, thereby being triggered by the iron core 242; conversely, when not fully engaged, i.e., the latching mechanism 241 is still in the unlocked position, the trigger 245 is separated from the iron core 242, and the trigger 245 cannot be triggered.

[0153] Water supply procedure: With the locking mechanism in place, the cleaning base station 2 is controlled to supply water via the water supply valve assembly 23. The water supply procedure can only be performed when the locking mechanism is in place, i.e., when the trigger 245 is activated. Throughout the water supply process, the locking assembly remains in the locked position, ensuring that the cleaning device 1 remains stably locked to the cleaning base station 2. After the water supply operation is completed, the cleaning base station 2 is controlled to close the water supply valve assembly 23. Once liquid stops flowing from the water supply valve assembly 23, the locking of the cleaning device 1 can be discontinued.

[0154] Unlocking steps: The locking assembly moves to the unlocked position based on a second signal; the second signal is a water filling completion signal, which can be a water filling time reaching a set duration, a clean water tank 14 being full, or a wastewater tank 13 being full, etc. Based on the second signal, a signal is sent to de-energize the electromagnet 243. After de-energization, the electromagnetic force on the iron core 24 of the electromagnet 243 disappears, and it can drive the locking mechanism 241 to move to the unlocked position under the action of elastic force.

[0155] If the locking assembly successfully moves to the locked and unlocked positions each time power is applied and de-energized, the water filling operation can be completed by sequentially executing the aforementioned locking, water filling, and unlocking steps. However, in practical applications, due to reasons such as locking assembly malfunction, inaccurate docking between cleaning equipment 1 and water valve assembly 23, or failure to transmit signals smoothly, the locking assembly may fail to lock properly after power is applied, and may fail to unlock properly after power is de-energized. Therefore, if... Figure 24 As shown, in one embodiment of this disclosure, the locking step further includes:

[0156] When the locking assembly is detected as not fully engaged, the locking assembly is controlled to repeatedly execute the unlocking and locking steps. If the trigger 245 is not triggered after the electromagnet 243 is energized, it indicates that the locking assembly is not fully engaged, and the electromagnet 243 needs to be de-energized and then energized again.

[0157] If the repeated locking is detected, the water filling step continues. If the trigger 245 sends a trigger signal after the electromagnet 243 is energized for the second time, it indicates that the second locking is successful. The cleaning device 1 is stably locked onto the cleaning base station 2, so the water filling step can continue, that is, the cleaning base station 2 is controlled to perform water filling operation through the water filling valve assembly 23.

[0158] If repeated locking is detected as incomplete, the water filling step is cancelled. If the trigger 245 is still not triggered after the electromagnet 243 is energized a second time, it indicates that the second locking was also incomplete, and the water filling operation command must be stopped. It is understandable that if the water filling step is still performed when the locking is incomplete, there is a risk of water overflow due to insufficient stability in the docking position between the water valve assembly 23 and the cleaning equipment 1.

[0159] After canceling the water supply step, charging and alarm functions can be activated. Since cleaning device 1 itself requires charging within cleaning base station 2, the inability to successfully lock will not affect the charging operation. Therefore, cleaning base station 2 can continue to supply power to cleaning device 1 normally. Cleaning device 1 or cleaning base station 2 can issue alarms by illuminating alarm lights, emitting alarm sounds, or sending alarm messages to the user's mobile phone, thus reminding the user to inspect and repair the locking components.

[0160] In one embodiment of this disclosure, reference is made to Figure 25 After the locking assembly moves to the unlock position based on the second signal, the unlocking step also includes a detection step to check whether the locking assembly is fully unlocked. When fully unlocked, the latch mechanism 241 is in the unlock position, the trigger 245 is separated from the iron core 242, and the trigger 245 will not be triggered; conversely, when unlocked but not fully unlocked, the trigger 245 can contact the iron core 242 and is thus triggered by the iron core 242.

[0161] When the locking assembly is detected as not fully unlocked, the locking assembly is controlled to repeat the locking and unlocking steps. If the trigger 245 remains triggered after the electromagnet 243 is de-energized, it indicates that the locking assembly is not fully unlocked. In this case, the electromagnet 243 needs to be energized and then de-energized again.

[0162] Understandably, after each repeated locking and unlocking step, the position of the locking component is checked: if the repeated unlocking is detected, it means that the locking component has successfully reset to the unlocked position after the last power failure, and the program can end at this time; if the repeated unlocking is detected, the locking and unlocking steps can be repeated again.

[0163] In one specific embodiment of this disclosure, a threshold number of repetitions can be set. If the number of repetitions of the locking and unlocking steps does not exceed the threshold number, the loop continues even if the unlocking is not complete. If the number of repetitions of the locking and unlocking steps exceeds the threshold number, the loop stops. Specifically, the threshold number can be set to 1: if the unlocking is not complete after the first repetition, a second repetition can be performed; if the unlocking is still not complete after the second repetition, the loop stops because the number of repetitions has exceeded the threshold number.

[0164] If repeated unlocking failures are detected, the detection step of checking whether the locking component is fully unlocked continues. If the locking component is still not fully unlocked after the last repetition, the power-on and power-off attempts will not be repeated. Instead, the electromagnet 243 will be kept in the de-energized state, and the position information of the locking component will be continuously monitored. It is understandable that if the locking component remains in the locked position when the electromagnet 243 is de-energized, the locking component may be stuck. It may naturally spring back to its original position after a period of stillness. Therefore, it is unnecessary to repeatedly attempt power-on and power-off; simply continuing the detection step is sufficient.

[0165] In one embodiment of this disclosure, the self-cleaning operation of the cleaning system includes a locking step, a water filling step, and an unlocking step. The self-cleaning operation includes two categories: a first category requiring a water filling step and a second category not requiring a water filling step. Specifically, the self-cleaning operation of the cleaning system may include multiple steps, such as: injecting clean water into the clean water tank 14, rinsing the wastewater tank 13, self-cleaning the roller brush 121, and emptying the wastewater tank 13. Steps requiring the water filling valve assembly 23 (e.g., injecting clean water into the clean water tank 14, rinsing the wastewater tank 13) are classified as first-category operations; steps not requiring the water filling valve assembly 23 (e.g., self-cleaning of the roller brush 121, emptying the wastewater tank 13) are classified as second-category operations.

[0166] During self-cleaning operations, Type I and Type II operations may be performed alternately, or multiple Type I operations and multiple Type II operations may be performed continuously. When performing Type I operations, the aforementioned locking, water filling, and unlocking steps need to be executed sequentially. During the unlocking step, if it is detected that the locking component is not fully unlocked, the locking component is controlled to repeat the locking and unlocking steps in Type II operations, while the self-cleaning operation continues.

[0167] If the locking component is not fully unlocked, it means the locking assembly is still in the unlocked position. If the upcoming self-cleaning operation is still a Type I operation, the locking and unlocking steps should not be repeated. The locking assembly only needs to remain in its current state to stably lock the cleaning device 1 onto the cleaning base station 2. If the upcoming self-cleaning operation is a Type II operation, the locking and unlocking steps can be repeated while performing the Type II operation. This involves repeatedly energizing and de-energizing the electromagnet 243 to attempt to reset the locking assembly to the unlocked position. Repeated attempts will not affect the self-cleaning operation because the Type II operation does not use the water inlet valve assembly 23, and whether it is locked or not will not affect the Type II operation.

[0168] As mentioned earlier, if the locking component fails to unlock after multiple attempts to power on and off, and the number of repetitions reaches a threshold, the process will stop. Instead, the electromagnet 243 will remain de-energized, and the position information of the locking component will be continuously monitored. During this process, both Type I and Type II operations can proceed normally without the program terminating due to the locking component's failure to unlock.

[0169] After the self-cleaning operation is completed, if the locking component is still not fully unlocked, an alarm signal is issued. Specifically, after the self-cleaning operation is completed, charging and alarm functions can be activated. The inability to fully unlock will not affect the charging operation, thus ensuring that the cleaning base station 2 can continue to supply power to the cleaning device 1. The cleaning device 1 or the cleaning base station 2 can issue an alarm by illuminating an alarm light, emitting an alarm sound, or sending an alarm message to the user's mobile phone, thereby reminding the user to inspect and repair the locking component.

[0170] In one embodiment of this disclosure, the longest energizing time of the electromagnet 243 is ≤60 seconds. The continuous energizing time of the electromagnet 243 should not exceed one minute. If the energizing time of the electromagnet 243 is too long, it will overheat, easily reducing its lifespan and causing the locking assembly to malfunction. During self-cleaning operations, the operation time of each first-type operation requiring the water inlet valve assembly 23 should also not be too long. The single locking time of the locking assembly should not exceed 60 seconds, and each first-type operation should be completed within 60 seconds.

[0171] In one embodiment of this disclosure, the cleaning device 1 includes a clean water tank 14, and the water supply valve assembly 23 includes a second water valve 232 for docking with the clean water tank 14. The water supply step includes:

[0172] First liquid injection step: Based on the first liquid injection command, control the cleaning base station 2 to inject cleaning liquid into the clean water tank 14 through the second water valve 232;

[0173] Second liquid injection step: Based on the second liquid injection command, control the cleaning base station 2 to inject clean water into the clean water tank 14 through the second water valve 232;

[0174] The first and second injection steps are not performed simultaneously. In the cleaning base station 2, cleaning fluid and clean water are stored in separate containers and supplied to the second water valve 232 through their respective pipelines. The two pipelines converge at the second water valve 232, thus connecting to the clean water tank 14. Since the amount of clean water added is significantly greater than that of the cleaning fluid, the pressure of the clean water added is also much greater than that of the cleaning fluid added. If the first and second injection steps are performed simultaneously, the cleaning fluid will be difficult to pump smoothly into the clean water tank 14. Therefore, the first and second injection steps need to be performed in a staggered manner. For example, the first injection command can be sent first to control the cleaning base station 2 to inject cleaning fluid into the clean water tank 14 through the second water valve 232; after the cleaning fluid injection is completed, the second injection command 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.

[0175] In one specific embodiment of this disclosure, the cleaning solution and clean water can be mixed after being injected into the clean water tank 14. The resulting solution should be controlled at a certain concentration; specifically, the ratio of cleaning solution to clean water is approximately 1:50. The concentration of the cleaning solution should not be too high, otherwise cleaning solution residue will remain on the cleaned work surface; the concentration of the cleaning solution should not be too low, otherwise the cleaning effect will be insufficient. It is understood that the amount of cleaning solution added is closely related to the actual amount of solution in the clean water tank 14: when there is still residual liquid in the clean water tank 14, the amount of cleaning solution to be added is smaller; when the clean water tank 14 is basically empty, the amount of cleaning solution to be added is larger.

[0176] In this embodiment, a liquid level float can be installed in the storage chamber 140 of the clean water tank 14. The liquid level float is mainly used to detect whether the tank is full. Since the current liquid level in the clean water tank 14 cannot be directly monitored, the first liquid injection step includes the following steps to determine the amount of cleaning fluid to be added:

[0177] Obtain the working time of cleaning equipment 1;

[0178] If the working time of cleaning device 1 is greater than or equal to the working time threshold, the current injection time is determined to be the maximum injection time. Specifically, the working time threshold of cleaning device 1 is the maximum operating time of the clean water tank 14. For example, the working time threshold can be 40 minutes. When the working time of 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 injection volume of cleaning fluid can be determined to be the maximum injection volume. The current injection time of the peristaltic pump used to inject the cleaning fluid is also the maximum injection time. For example, the peristaltic pump can be controlled to work for 10 seconds, and 17 ml of cleaning fluid can be pumped in 10 seconds. 17 ml of cleaning fluid is the maximum injection volume of cleaning fluid.

[0179] If the working time of cleaning device 1 is less than the working time threshold, the current injection time is calculated based on the ratio between the working time of cleaning device 1 and the working time threshold, as well as the maximum injection time. For example, if the working time of cleaning device 1 is 20 minutes, which is less than the working time threshold (40 minutes), and the ratio between the working time of cleaning device 1 and the working time threshold is 0.5, it can be assumed that 50% of the liquid remains in the clean water tank 14; multiplying the maximum injection time (10 seconds) by the above ratio (0.5) yields a current injection time of 5 seconds, and the current injection volume of cleaning fluid is 8.5 ml.

[0180] Based on the current injection duration, a first liquid addition command is sent. Cleaning fluid is pumped according to the calculated injection duration. After injection is complete, a second liquid addition command can be sent, controlling the cleaning base station 2 to inject clean water into the clean water tank 14 via the second water valve 232 until the level float detects a full water signal. This control method only needs to calculate the current injection duration of the cleaning fluid, without requiring additional calculation of the clean water injection duration. Simultaneously, the solution in the clean water tank 14 maintains a relatively constant concentration, enabling the cleaning device 1 to achieve a stable cleaning effect.

[0181] Application Scenario 1

[0182] In the embodiment where the cleaning equipment disclosed herein is a handheld floor scrubber, when using the floor scrubber for cleaning work, the user can push the floor scrubber to move across the work surface and clean the work surface. After cleaning, the user can place the floor scrubber on the cleaning base station 2 for maintenance, such as charging, refilling water, and draining waste.

[0183] 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. The base 21 is used to dock with the body 11 of the floor scrubber. The wastewater tank 13 installed on the body 11 can dock with the drain trough assembly 211 on the base 21. The dirt in the wastewater tank 13 can be discharged into the drain trough assembly 211 under the action of gravity, and the drain trough assembly 211 can perform subsequent discharge treatment of the dirt.

[0184] The tray 22 is used to support the floor brush assembly 12 of the floor scrubber. The bottom of the floor brush assembly 12 may be provided with a charging port 125, and the tray 22 is provided with a charging part. When the floor scrubber is connected to the cleaning base station 2, the protruding charging part on the tray 22 can extend into the charging port 125, and the two can form a circuit connection, thereby realizing that the cleaning base station 2 charges the floor scrubber.

[0185] The bottom of the floor brush assembly 12 is provided with a groove 15, in which there are a first docking part 151 and a second docking part 152; a water inlet valve assembly 23 is provided on the tray 22 above the top end face, the water inlet valve assembly 23 includes a first water valve 231 and a second water valve 232 arranged adjacent to each other. The water inlet valve assembly 23 can be docked into the groove 15, so that the first water valve 231 is docked with the first docking part 151 and the second water valve 232 is docked with the second docking part 152, thereby rinsing the wastewater tank 13 of the floor scrubber and replenishing the clean water tank 14 of the floor scrubber.

[0186] This disclosure arranges both the first water valve 231 and the second water valve 232 on the tray 22, ensuring that both valves are located at the lowest position of the cleaning base station 2. The floor scrubber can then stably dock under its own weight. Furthermore, the water at the valves is collected by the tray 22, preventing it from affecting other components. For example, the charging contact 224 on the charging unit can be positioned higher than the upper water valve assembly 23, thus preventing water from the first water valve 231 and the second water valve 232 from flowing to the charging contact 224, effectively preventing leakage or short circuit accidents and improving the safety of the cleaning base station 2. In addition, the proximity of the first water valve 231 and the second water valve 232 increases the integration of the upper water valve assembly 23. The floor brush assembly 12 can have only one slot 15 for docking with the upper water valve assembly 23, eliminating the need for separate holes for docking the first water valve 231 and the second water valve 232.

[0187] Application Scenario 2

[0188] In the embodiment where the cleaning equipment disclosed herein is a handheld floor scrubber, when using the floor scrubber for cleaning work, the user can push the floor scrubber to move across the work surface and clean the work surface. After cleaning, the user can place the floor scrubber on the cleaning base station 2 for maintenance, such as charging, refilling water, and draining waste.

[0189] 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. The tray 22 is provided with a water supply valve assembly 23, which includes a first water valve 231 and a second water valve 232 arranged adjacent to each other, and a mounting base 233. The mounting base 233 has two adjacent mounting holes 230, with the first water valve 231 and the second water valve 232 respectively located within the corresponding mounting holes 230.

[0190] A locking assembly is provided on the mounting base 233, which can be located between the first water valve 231 and the second water valve 232. When the machine moves to the locking position, the locking assembly can cooperate with the floor brush assembly 12 of the floor scrubber, thereby locking the floor brush assembly 12 onto the tray 22; when the machine moves to the unlocking position, the locking assembly can disengage from the floor brush assembly 12.

[0191] The locking assembly includes a locking mechanism 241 hinged to the mounting base 233, and a driving mechanism consisting of an electromagnet 243 and an iron core 242. The locking mechanism 241 moves between a locked position and an unlocked 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 locked position, the hook 2410 can lock the floor brush assembly 12 onto the tray 22; when in the unlocked position, the hook 2410 can disengage from the floor brush assembly 12.

[0192] When energized, the iron core 242 located inside the electromagnet 243 moves under the influence of electromagnetic induction, causing the locking mechanism 241 to rotate, thereby moving the locking mechanism 241 from the unlocked position to the locked position. The driving mechanism also includes a first elastic element 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 from the locked position to the unlocked position under the elastic force of the first elastic element 244.

[0193] This disclosure improves the stability of the docking between the floor scrubber and the cleaning base station 2 by incorporating a locking component. Specifically, the locking component securely locks the floor scrubber to the base station body, preventing the water pressure from the cleaning base station 2 when supplying water to the floor scrubber from lifting it up, thereby preventing water leakage. Furthermore, directly installing the locking component on the water inlet valve assembly 23 helps balance the water pressure impact during water supply, further enhancing the stability of the docking.

[0194] Application Scenario 3

[0195] In an embodiment where the cleaning equipment disclosed herein is a handheld floor scrubber, when a user uses the floor scrubber to perform cleaning work, the user can push the floor scrubber to move on the work surface and clean the work surface.

[0196] The floor scrubber includes a body 11 and a floor brush assembly 12 connected to the bottom of the body 11. 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. The roller brush cover 122 is configured to be detachably connected to the floor brush housing 120 according to a preset assembly / disassembly path, and is configured to form a roller brush cavity with the floor brush housing 120. The roller brush 121 is located within the roller brush cavity and is configured to be rotatably connected to the floor brush housing 120.

[0197] The clean water tank 14 is detachably connected to the brush housing 120. The clean water tank 14 has a liquid storage chamber 140, which is configured to extend from a position corresponding to the brush housing 120 to the disassembly path of the roller brush cover 122. The liquid storage chamber 140 can be installed on the top of the brush housing 120 and extends forward above the roller brush cover 122. The disassembly path of the roller brush cover 122 can be vertically upward, and the liquid storage chamber 140 extending above the roller brush cover 122 has a large capacity.

[0198] To maximize the capacity of the reservoir 140, the projected area of ​​the clean water tank 14 on the working surface needs to be maximized. The reservoir 140 can be configured to cover the top end face of the floor brush housing 120. In this case, the reservoir 140 can completely cover the upper surface of the roller brush cover 122, and the top end face of the clean water tank 14 surrounds the entire upper surface of the floor brush assembly 12, thereby maximizing the capacity of the reservoir 140.

[0199] This disclosure reduces the weight of the machine body 11 by placing the clean water tank 14 on the brush housing 120, making it easier for the user to push the floor scrubber. Furthermore, the clean water tank 14, located on the brush housing 120, increases the downward pressure on the brush assembly 12, thereby improving the cleaning effect of the roller brush 121 on the work surface. The water storage chamber 140 of the clean water tank 14 extends to a position located on the disassembly path of the roller brush cover 122, allowing the clean water tank 14 to be integrated simultaneously with the roller brush cover 122 onto the brush assembly 12. Moreover, the capacity of the outwardly extending storage chamber 140 is also increased, providing enough water for a full house cleaning without the need for repeated refills, thus improving the user experience.

[0200] Application Scenario 4

[0201] In the embodiment where the cleaning equipment disclosed herein is a handheld floor scrubber, when using the floor scrubber for cleaning work, the user can push the floor scrubber to move across the work surface and clean the work surface. After cleaning, the user can place the floor scrubber on the cleaning base station 2 for maintenance, such as charging, refilling water, and draining waste.

[0202] During the self-cleaning operation, the instruction to flush wastewater tank 13 needs to be executed:

[0203] Locking steps: When the electromagnet 243 is energized, the locking mechanism 241 moves to the locking position; after the first energization, it is detected that the locking assembly is not fully locked, the electromagnet 243 is de-energized and then energized again, and it is detected that the locking is fully engaged.

[0204] Water supply procedure: With the locking mechanism in place, the cleaning base station 2 is controlled to flush the wastewater tank 13 via the first water valve 231. Throughout the flushing process, the locking assembly remains in the locked position, ensuring that the cleaning device 1 remains stably locked onto the cleaning base station 2 during flushing. After flushing is completed, the cleaning base station 2 is controlled to close the water supply valve assembly 23. Once no more liquid flows from the water supply valve assembly 23, the locking of the cleaning device 1 can be discontinued.

[0205] Unlocking steps: The electromagnet 243 is de-energized, and the locking mechanism 241 moves to the unlocked position. After the first power-off, it is detected that the locking component is not fully unlocked. The roller brush 121 of the cleaning device 1 is performing self-cleaning, i.e., performing the second type of operation. The state of the locking component will not affect the second type of operation. Therefore, the electromagnet 243 can be repeatedly energized and de-energized. After repeating this process twice, if the locking component is still not fully unlocked, the process will stop. Instead, the electromagnet 243 will be kept in the de-energized state, and the position information of the locking component will be continuously monitored.

[0206] After the self-cleaning process is completed, if the locking component is still not fully unlocked, the system will charge and trigger an alarm to remind the user to come and inspect and repair the locking component.

[0207] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
