[0002] This application claims priority to Chinese Patent Application No. 202410502990.2, filed on April 24, 2024, with the China National Intellectual Property Administration, entitled "Cleaning Equipment and Liquid Drainage Method, Apparatus, System and Storage Medium Thereof", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of cleaning equipment, and more specifically to a cleaning device and its liquid drainage method, apparatus, system and storage medium. Background Technology

[0004] As people's work pace accelerates and their living standards continue to rise, they are increasingly accustomed to using smart cleaning appliances to replace manual labor in tasks such as sweeping, vacuuming, and mopping. Among these, floor scrubbers and robotic vacuum cleaners are particularly popular.

[0005] Floor scrubbers typically come equipped with components such as roller brushes, clean water tanks, and wastewater tanks. Base stations compatible with floor scrubbers can also be equipped with clean water tanks and wastewater tanks, enabling the base station to perform tasks such as water replenishment, waste removal, and charging of the floor scrubber.

[0006] When a floor scrubber or base station malfunctions, the user can return it to the after-sales service center for repair. Usually, the user will clean the residual water from the floor scrubber and base station before returning them. However, it is possible that the user forgets to drain the residual water. In this case, the after-sales personnel need to manually drain the residual water from the floor scrubber and base station. However, manually draining the liquid is a cumbersome process, and if it is forgotten, the residual water can easily damage the machine. Even if the user has drained the liquid before returning it, there may still be a small amount of residual water in the internal pipes and other parts of the machine. Even a small amount of residual water can cause damage to the machine.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0051] Cleaning equipment, such as floor scrubbers and robotic vacuum cleaners, typically consists of a base station and a main unit. The base station is primarily responsible for water supply, wastewater recycling and treatment, providing power to the main unit, and storage and organization. The main unit is the core component, directly responsible for performing the cleaning tasks. Cleaning equipment includes water system components, which are related to water circulation in the base station and main unit to achieve their functions. These include the base station's clean water tank, base station's wastewater tank, base station's spray pump, the main unit's clean water tank, the main unit's wastewater tank, the main unit's spray pump, cleaning components (such as roller brushes), and water pumps that provide the necessary liquid for the cleaning components to perform their cleaning work. At least one of the base station's wastewater tank or the main unit's wastewater tank can serve as a wastewater recycling component for the entire cleaning equipment. When the main unit or base station of the cleaning equipment malfunctions and the user returns it to the after-sales service center, residual liquid may remain in the aforementioned water system components and in the pipes connecting the water system components. If this residual liquid is not drained, it can easily damage the machine. Therefore, this disclosure provides the following cleaning equipment and its liquid draining method, apparatus, system and storage medium, which enable liquid draining before the cleaning equipment is sold to avoid residual water damaging the machine, without the need for manual liquid draining after the sale.

[0052] Example 1

[0053] A liquid draining method is used in a cleaning device equipped with a water system component, the water system component including a wastewater recovery component; the cleaning device is equipped with a liquid draining button, as shown in Figure 1, and the method includes:

[0054] S1: Receives the trigger signal from the liquid drain button.

[0055] S2: In response to the trigger signal, control the water system components to operate for a preset time, so that the residual liquid in the water system components is discharged to the outside of the cleaning equipment and / or concentrated in the wastewater recovery component.

[0056] In this embodiment, a liquid drain button is configured on the cleaning equipment. This button provides a trigger signal for liquid draining, facilitating one-button initiation of the entire liquid draining process. Upon receiving the trigger signal from the liquid drain button, in response to this signal, the components related to the water circulation of the entire cleaning equipment (i.e., the water system components) are controlled to operate for a preset time, causing residual liquid in the water system components to be discharged to the outside of the cleaning equipment and / or collected in the wastewater recovery component, thus achieving one-button draining of residual liquid in the water system components.

[0057] The liquid draining method in this embodiment, by operating the liquid draining button configured on the cleaning equipment before after-sales service, and based on the response to the signal provided by the button, realizes one-click liquid draining of residual liquid in the water system components of the cleaning equipment before after-sales service, avoids damage to the machine by residual liquid, ensures the service life of the machine, eliminates the need for manual draining of residual liquid after after-sales service, saves after-sales operation procedures, and improves the intelligence level of the equipment.

[0058] In this embodiment, discharging residual liquid from the water system components to the outside of the cleaning equipment means that when the cleaning equipment has an external sewage discharge pipe connected to the wastewater recovery component, operating the liquid drain button before maintenance will automatically discharge the residual liquid from the water system components to the outside of the cleaning equipment, thus emptying the cleaning equipment. Discharging residual liquid from the water system components to the wastewater recovery component of the cleaning equipment means that when the wastewater recovery component is not connected to the outside, operating the liquid drain button before maintenance will automatically collect the residual liquid from the water system components into the wastewater recovery component, where it will then be processed, similarly emptying the cleaning equipment. Of course, when the wastewater recovery component of the cleaning equipment is connected to the outside through a sewage discharge pipe, the residual liquid can either be discharged to the outside or collected in the wastewater recovery component, depending on the specific circumstances.

[0059] The cleaning equipment includes a base station and a host. In an optional embodiment, the wastewater recycling component is specifically a base station wastewater tank located in the base station and / or a host wastewater tank located in the host.

[0060] When residual liquid is collected in the wastewater recovery component, it can be collected in the base station wastewater tank and / or the host wastewater tank, eliminating the need for additional wastewater recovery components and simplifying the structure of the entire cleaning equipment.

[0061] In this embodiment, the liquid drain button can be set on either the base station or the host, depending on the specific situation.

[0062] In optional embodiments, the liquid drain button can be located on the host and / or base station. In one example, a separate button can be used as the liquid drain button; in another example, a combination button can be used. For example, if the host has a power button and a self-cleaning button, the combination of the power button and the self-cleaning button can be used as the liquid drain button, that is, when the user presses the power button and the self-cleaning button simultaneously, a trigger signal for the liquid drain button will be generated.

[0063] In an optional embodiment, the water system components further include a base station clean water tank, a main unit clean water tank, and a base station spray pump; the base station spray pump is connected to the base station clean water tank and is used to extract liquid from the base station clean water tank.

[0064] S2 includes:

[0065] S21: In response to the trigger signal, control the base station spray pump to operate until the base station water tank reaches a water shortage state and the water shortage state is maintained for a first preset time, so that the residual liquid in the base station water tank and the residual liquid in the pipe connected to the base station spray pump are discharged to the outside of the cleaning equipment and / or concentrated in the sewage recycling component.

[0066] When a cleaning device equipped with a base station and a main unit performs a cleaning task, the base station's clean water tank stores clean water and delivers it to the main unit's clean water tank via pipes for the main unit to perform the cleaning work. The main unit's clean water tank provides clean water to the main unit's cleaning components (such as roller brushes), which then clean the areas that need cleaning.

[0067] In an optional embodiment, the water system components also include a base station wastewater tank, which recycles wastewater generated during the host cleaning process. During the wastewater recycling process in the base station wastewater tank, a base station spray pump draws clean water from the base station clean water tank and sprays it through nozzles to clean the base station wastewater tank.

[0068] In an optional embodiment, the water system components also include a main unit wastewater tank, which also recycles wastewater generated during the main unit cleaning process.

[0069] In an optional embodiment, the host is equipped with a device for issuing prompts, such as a voice module and / or an ambient light. When the user presses the liquid drain button, the voice module plays "Please wait," and / or the ambient light turns on to remind the user that the cleaning equipment is about to enter the liquid drain state.

[0070] In an optional embodiment, the base station and / or host is equipped with an in-situ switch for the water system component (e.g., an in-situ switch for the base station's clean water tank). When the user operates the liquid drain button and the in-situ switch for the water system component, the response process of the trigger signal of the liquid drain button is formally initiated, and the liquid is drained according to the process in S2.

[0071] In this embodiment, in response to the trigger signal provided by the liquid drain button, the base station spray pump is controlled to operate, thereby realizing the draining of residual liquid in the base station water tank and the pipeline connected to the base station spray pump.

[0072] In an optional embodiment, in S21, the base station water tank may be equipped with a water level detection device, such as a water level sensor, which can detect the water level in the base station water tank in real time. Using the water level sensor, it can be determined when the base station water tank reaches a water shortage state and maintain the water shortage state for a first preset time, thereby helping to realize the one-click liquid drainage of the entire cleaning system.

[0073] In an optional embodiment, the water system component further includes a water injection component, through which the base station water tank injects water into the host water tank.

[0074] The method also includes: controlling the water injection component to stop operating in response to a trigger signal.

[0075] Specifically, in response to the trigger signal, the water injection component is first controlled to stop operating, that is, the pipeline between the base station water tank and the host water tank is cut off, so that the base station cannot inject water into the host. This facilitates the subsequent separate emptying of the residual liquid in the base station water tank and the pipeline connected to the base station spray pump, avoiding the impact of the water injection process on the emptying of the liquid in the base station water tank.

[0076] In an optional embodiment, the water injection assembly includes a base station water injection solenoid valve, a water injection pump, and a main unit water injection solenoid valve, sequentially disposed between the base station water tank and the main unit water tank. The base station water injection solenoid valve controls the opening and closing of the pipeline between the base station water tank and the water injection pump, and the main unit water injection solenoid valve controls the opening and closing of the pipeline between the water injection pump and the main unit water tank; the water injection pump is used to extract liquid from the base station water tank and transfer it to the main unit water tank.

[0077] The above-mentioned response to the trigger signal to control the water injection components to stop operating includes: responding to the trigger signal to control the base station water injection solenoid valve, the host water injection solenoid valve and the water injection pump to all stop operating.

[0078] Specifically, a connecting pipe exists between the base station water tank and the main unit water tank, facilitating the transfer of clean water from the base station water tank to the main unit water tank. A base station water injection solenoid valve, a water injection pump, and a main unit water injection solenoid valve are sequentially installed within this pipe, allowing for independent control of the operation of both the base station and main unit water tanks, while also ensuring more efficient injection of clean water from the base station water tank into the main unit water tank.

[0079] In this embodiment, upon receiving a trigger signal from the liquid drain button, the system responds by stopping the operation of the base station water injection solenoid valve, the water injection pump, and the host water injection solenoid valve. This completely cuts off the pipeline between the base station water tank and the host water tank, ensuring that the base station cannot inject water into the host. This facilitates the one-button draining of residual liquid from the base station water tank and the pipeline connected to the base station spray pump.

[0080] In an optional embodiment, after S21, the method further includes:

[0081] S22: Control the water injection component to operate for a second preset time, so that the residual liquid in the pipe between the base station water tank and the host water tank is discharged to the outside of the cleaning equipment and / or concentrated in the sewage recovery component.

[0082] After the residual liquid in the base station water tank and the pipe connected to the base station spray pump is emptied, the water injection component is controlled to run for a second preset time, that is, the pipe between the base station water tank and the host water tank is opened, so that the base station water tank injects water into the host water tank for the second preset time, thereby realizing the emptying of the residual liquid in the pipe between the base station water tank and the host water tank.

[0083] Specifically, in S22, controlling the water injection components to run for a second preset duration means controlling the base station water injection solenoid valve, the host water injection solenoid valve, and the water injection pump to all run for a second preset duration.

[0084] In an optional embodiment, the main unit is provided with a cleaning component, and the water system component further includes a water pump for drawing liquid from the main unit's clean water tank for the cleaning component to perform cleaning work.

[0085] Following S22, the method further includes:

[0086] S23: Control the operation of the water spray pump until the main unit's clean water tank reaches a water shortage state and the water shortage state is maintained for a third preset time, so that the residual liquid in the main unit's clean water tank and the residual liquid in the pipe connected to the water spray pump are discharged to the outside of the cleaning equipment and / or collected in the wastewater recovery component.

[0087] When the main unit performs cleaning work, the water pump starts, draws clean water from the main unit's clean water tank and provides it to the cleaning component. The cleaning component then starts and uses the clean water to clean the area that needs to be cleaned.

[0088] In this embodiment, the water pump is controlled to operate only after the residual liquid in the pipe between the base station's clean water tank and the main unit's clean water tank has been emptied. This facilitates the start-up control of emptying the residual liquid in the main unit's clean water tank and the pipe connected to the water pump. When the main unit's clean water tank reaches a water shortage state and remains in this state for a third preset time, it indicates that the residual liquid in the main unit's clean water tank and the pipe connected to the water pump has been emptied, thus achieving one-click emptying of the residual liquid in the main unit's clean water tank and the pipe connected to the water pump.

[0089] Similar to the water shortage situation in the base station's water tank, the main unit's water tank is also equipped with a device for detecting the water level, namely a water level sensor. Using this water level sensor, it is possible to determine when the main unit's water tank reaches a water shortage state and maintain the water shortage state for a third preset time, thereby facilitating the realization of one-click liquid emptying of the entire cleaning system.

[0090] In an optional embodiment, the water system component further includes a main unit spray pump, which is connected to the main unit clean water tank and is used to extract liquid from the main unit clean water tank.

[0091] S2 also includes:

[0092] S24: In response to the trigger signal, control the main spray pump to run for a fourth preset time, so that the residual liquid in the pipe connected to the main spray pump is discharged to the outside of the cleaning equipment and / or collected in the wastewater recovery component.

[0093] Similar to the base station sprinkler pump, the host sprinkler pump can be used to extract the liquid from the host's clean water tank, and the extracted wastewater can be discharged into the sewer or sewage treatment facility.

[0094] Upon receiving a trigger signal from the liquid drain button, the system responds to the trigger signal by controlling the operation of the main spray pump. This enables the start-up control of draining residual liquid in the pipe connected to the main spray pump. When the operation reaches the fourth preset time, it can be considered that the residual liquid in the pipe connected to the main spray pump has been drained, thus achieving one-button draining of residual liquid in the pipe connected to the main spray pump.

[0095] It should be noted that in this embodiment, step S24 can be executed before steps S21 to S23, after steps S21 to S23, or simultaneously with steps S21 to S23. This embodiment does not impose any restrictions.

[0096] It should be understood that the first preset duration, the second preset duration, the third preset duration and the fourth preset duration can be the same, such as all being 10 seconds, or they can be different, depending on the specific circumstances. This embodiment does not impose any restrictions.

[0097] A complete process of the liquid drainage method in this embodiment is shown in Figure 2, and its specific process is as follows:

[0098] The first step is to detect the operation of the liquid drain button, for example, by detecting that the user or after-sales personnel simultaneously press the main unit power button and the self-cleaning button on the main unit.

[0099] Furthermore, in-situ detection of water system components can be performed before the liquid is drained, such as detecting the operation of in-situ switches for water system components. Taking the base station water tank as an example, after detecting that the in-situ switch of the base station water tank has been pressed, the second step continues.

[0100] Furthermore, upon detecting the operation of the liquid drain button or the presence detection of water system components, prompts can be issued, such as a voice message saying "Please wait" or illuminating the ambient lights in the clean water tank and / or wastewater tank.

[0101] The second step is to receive the trigger signal from the liquid drain button.

[0102] The third step involves, on the one hand, responding to the trigger signal, controlling the base station water tank solenoid valve, the host water tank solenoid valve, and the water injection pump to stop operating, and controlling the base station spray pump to operate until the base station water tank reaches a water shortage state and the water shortage state is maintained for a first preset time (specifically 10 seconds); on the other hand, responding to the trigger signal, controlling the host spray pump to operate for a fourth preset time (specifically 10 seconds).

[0103] The fourth step is to control the base station water tank to run for a second preset time (specifically 10 seconds) after the water tank reaches a water shortage state and the water shortage state is maintained for a first preset time.

[0104] Fifth step: After the control base station water tank solenoid valve, the host water tank solenoid valve and the water pump have all run for the second preset time (specifically 10 seconds), control the water pump to run until the host water tank reaches a water shortage state and the water shortage state is maintained for the third preset time (specifically 10 seconds); complete the one-click emptying of liquid.

[0105] Example 2

[0106] A liquid draining device is used in a cleaning device equipped with a water system component, the water system component including a wastewater recovery component; the cleaning device is equipped with a liquid draining button; the device is applied in the liquid draining method of Embodiment 1, as shown in Figure 3, and includes:

[0107] The liquid evacuation trigger module is used to receive the trigger signal from the liquid evacuation button.

[0108] The drain control module is used to control the water system components to operate for a preset time in response to a trigger signal, so that the residual liquid in the water system components is discharged to the outside of the cleaning equipment and / or concentrated in the wastewater recovery component.

[0109] In this embodiment, a liquid drain button is configured on the cleaning equipment. This button provides a trigger signal for liquid draining, facilitating one-button initiation of the entire liquid draining process. When the drain trigger module receives the trigger signal from the liquid drain button, the drain control module responds by controlling the components related to the water circulation of the entire cleaning equipment (i.e., the water system components) to operate for a preset duration. This causes residual liquid in the water system components to be discharged to the outside of the cleaning equipment and / or collected in the wastewater recovery component, thus achieving one-button draining of residual liquid from the water system components.

[0110] The liquid draining device in this embodiment, by operating the liquid draining button configured on the cleaning equipment before after-sales service, realizes one-click liquid draining of residual liquid in the water system components of the cleaning equipment based on the response to the signal provided by the button, avoiding damage to the machine by residual liquid, ensuring the service life of the machine, eliminating the need for manual draining of residual liquid after after-sales service, saving after-sales operation procedures, and improving the intelligence level of the equipment.

[0111] Specifically, the cleaning equipment includes a base station and a host, and the wastewater recycling component is specifically a base station wastewater tank located in the base station and / or a host wastewater tank located in the host.

[0112] In an optional embodiment, the water system components further include a base station clean water tank, a main unit clean water tank, a base station sprinkler pump, and a water injection assembly disposed between the base station clean water tank and the main unit clean water tank. The base station clean water tank injects water into the main unit clean water tank through the water injection assembly; the base station sprinkler pump is connected to the base station clean water tank and is used to extract liquid from the base station clean water tank.

[0113] As shown in Figure 4, the evacuation control module includes a main controller, a water injection control component, and a first spray pump control component.

[0114] The main controller is used to send a first control command to the water injection control component in response to a trigger signal.

[0115] The water injection control component is electrically connected to both the main controller and the water injection component, and is used to control the water injection component to stop operating according to the first control command received.

[0116] The main controller is also used to send a second control command to the first spray pump control component after the water injection control component stops operating.

[0117] The first spray pump control component is electrically connected to both the main controller and the base station spray pump. It is used to control the operation of the base station spray pump according to the received second control command until the base station clean water tank reaches a water shortage state and the water shortage state is maintained for a first preset time, so that the residual liquid in the base station clean water tank and the residual liquid in the pipe connected to the base station spray pump are discharged to the outside of the cleaning equipment and / or concentrated in the sewage recovery component.

[0118] In the above-described drain control module, the main controller responds to the trigger signal provided by the liquid drain button. First, it sends a first control command to the water injection control component, which then stops the water injection component from operating, effectively cutting off the pipeline between the base station's clean water tank and the host's clean water tank. This prevents the base station from injecting water into the host, facilitating the separate draining of residual liquid from the base station's clean water tank and the pipeline connected to the base station's spray pump. This avoids the water injection process affecting the draining of liquid from the base station's clean water tank. Then, a second control command is sent to the first spray pump control component, which controls the operation of the base station's spray pump, thereby draining the residual liquid from the base station's clean water tank and the pipeline connected to the base station's spray pump.

[0119] In an optional embodiment, the base station's clean water tank is equipped with a first water level sensor.

[0128] In an optional embodiment, the water injection assembly includes a base station water injection solenoid valve, a water injection pump, and a main unit water injection solenoid valve, which are sequentially disposed between the base station water tank and the main unit water tank.

[0129] The base station water injection solenoid valve is used to control the opening and closing of the pipeline between the base station water tank and the water injection pump, and the host water injection solenoid valve is used to control the opening and closing of the pipeline between the water injection pump and the host water tank; the water injection pump is used to extract liquid from the base station water tank and transfer it to the host water tank.

This means that the first solenoid valve control component, the second solenoid valve control component, and the water injection pump control component control the base station water injection solenoid valve, the water injection pump, and the host water injection solenoid valve to stop operating. This completely cuts off the pipeline between the base station water tank and the host water tank, ensuring that the base station cannot inject water into the host, thus facilitating the one-button draining of residual liquid from the base station water tank and the pipeline connected to the base station spray pump.

[0149] In the first solenoid valve control assembly of the above structure, the base of the second transistor Q15 is connected to the second control command (specifically a level signal) sent by the main controller to control the switching of the second transistor Q15.

The source of the fourth MOSFET Q13 is connected to the base station water injection solenoid valve in sequence through the ferrite bead FB4 and the fuse F4. The second transistor Q15 is used to control the switching of the fourth MOSFET Q13, thereby controlling whether the base station water injection solenoid valve is running or not.

[0150] The specific circuit structure of the second solenoid valve control component used in this embodiment to control whether the main unit's water injection solenoid valve is running or not is the same as that of the first solenoid valve control component shown in Figure 7, and will not be listed here again.

[0151] In an optional embodiment, after the first spray pump control component controls the discharge of residual liquid in the base station water tank and residual liquid in the pipe connected to the base station spray pump to the outside of the cleaning equipment and / or to the wastewater recycling component, the main controller is further configured to send a third control command to the water injection control component.

[0152] The water injection control component is also used to: control the water injection component to run for a second preset duration according to the received third control command, so that the residual liquid in the pipe between the base station water tank and the host water tank is discharged to the outside of the cleaning equipment and / or concentrated in the wastewater recycling component.

[0153] After the residual liquid in the base station water tank and the pipe connected to the base station spray pump is emptied, the main controller sends a third control command to the water injection control component. The water injection control component then controls the water injection component to run for a second preset time, that is, to open the pipe between the base station water tank and the host water tank, so that the base station water tank injects water into the host water tank for the second preset time, thereby realizing the emptying of the residual liquid in the pipe between the base station water tank and the host water tank.

[0158] The water spray pump control component is used to control the operation of the water spray pump according to the received fourth control command until the main unit's clean water tank reaches a water shortage state and the water shortage state is maintained for a third preset time, so that the residual liquid in the main unit's clean water tank and the residual liquid in the pipe connected to the water spray pump are discharged to the outside of the cleaning equipment and / or collected in the wastewater recovery component.

[0159] After the residual liquid in the pipe between the base station water tank and the main unit water tank is emptied, the main controller sends a fourth control command to the water pump control component, which controls the operation of the water pump to facilitate the start-up control of emptying the residual liquid in the main unit water tank and the pipe connected to the water pump. When the main unit water tank reaches a water shortage state and the water shortage state is maintained for a third preset time, it indicates that the residual liquid in the main unit water tank and the pipe connected to the water pump has been emptied, thus realizing one-click emptying of the residual liquid in the main unit water tank and the pipe connected to the water pump.

[0161] The second water level sensor is electrically connected to the main controller and is used to detect the second water level data of the main unit's clean water tank and send the second water level data to the main controller.

[0162] The main controller is also used to determine whether the main unit's clean water tank is in a water shortage state based on the received second water level data.

[0163] Similar to the first water level sensor, the second water level data detected by the second water level sensor can determine when the main unit's clean water tank reaches a water shortage state and maintains the water shortage state for a third preset time, thereby helping to achieve one-click liquid emptying of the entire cleaning system.

[0170] In an optional embodiment, the water system component further includes a main unit spray pump, which is connected to the main unit wastewater tank and is used to extract liquid from the main unit wastewater tank.

[0171] As shown in Figure 4, the evacuation control module also includes a second spray pump control component, which is electrically connected to both the main controller and the main spray pump.

[0172] The main controller is used to send a fifth control command to the second spray pump control component in response to the trigger signal.

[0173] The second spray pump control component is used to control the main spray pump to run for a fourth preset time according to the received fifth control command, so that the residual liquid in the pipe connected to the main spray pump is discharged to the outside of the cleaning equipment and / or concentrated in the wastewater recovery component.

[0174] Upon receiving a trigger signal from the liquid drain button, the main controller responds to the trigger signal by sending a fifth control command to the second spray pump control component. The second spray pump control component then controls the operation of the main spray pump, thereby enabling the start-up control of draining residual liquid in the pipe connected to the main spray pump. When the operation reaches the fourth preset time, it can be considered that the residual liquid in the pipe connected to the main spray pump has been drained, thus achieving one-button draining of residual liquid in the pipe connected to the main spray pump.
