Description

[Technical Field]

[0001] This application relates to the field of smart homes, and more specifically, to a control method and apparatus for a cleaning device, a storage medium, and an electronic device. [Background Technology]

[0002] Currently, when cleaning equipment performs self-cleaning (or when the equipment has other cleaning needs), the main unit can be connected to the base station. Liquid is transferred from the main unit's liquid tank to the base station's liquid tank by opening the valve on the drain pipe of the main unit's liquid tank (which could be the drain pipe of the base station's liquid tank). The base station's liquid tank is typically larger than the main unit's liquid tank, improving the efficiency of the self-cleaning process and preventing the main unit from pausing operation when the main unit's liquid tank is full. When the base station's liquid tank is full, the liquid can be manually poured out or drained by opening the valve on the base station's liquid tank's drain pipe.

[0003] However, the current drain ports of the main unit liquid tank, the inlet ports of the base station liquid tank, and the drain port of the base station liquid tank are typically of limited size. This results in slow liquid transfer speeds between the two tanks and slow draining speeds from the base station liquid tank, consequently reducing the self-cleaning efficiency of the cleaning equipment. Therefore, the control methods for cleaning equipment in related technologies suffer from low self-cleaning efficiency. [Summary of the Invention]

[0004] The purpose of this application is to provide a control method and apparatus for cleaning equipment, a storage medium and an electronic device, so as to at least solve the problem of low self-cleaning efficiency of cleaning equipment in the control methods of cleaning equipment in the related art.

The device host includes a host liquid tank, and the base station includes a base station liquid tank, a drive assembly, a first switching valve, and a second switching valve. The method includes: responding to a suction command, controlling the first switching valve and the second switching valve to be in a first preset state, and controlling the drive assembly to operate, so that the base station liquid tank is in a negative pressure state, wherein the first switching valve and the second switching valve being in the first preset state is used to instruct the drive assembly to evacuate the base station liquid tank; responding to a drain command, controlling the first switching valve and the second switching valve to be in a second preset state, and controlling the drive assembly to operate, so that the base station liquid tank is in a positive pressure state, wherein the first switching valve and the second switching valve being in the second preset state is used to instruct the drive assembly to pressurize the base station liquid tank.

[0007] According to another aspect of the embodiments of this application, a control device for a cleaning device is also provided, comprising: the cleaning device including a device host and a base station, the device host including a host liquid tank, the base station including a base station liquid tank, a drive assembly, a first switching valve and a second switching valve; the device comprising: a first control unit, configured to, in response to a suction command, control the first switching valve and the second switching valve to be in a first preset state, and control the drive assembly to operate, so that the base station liquid tank is in a negative pressure state, wherein the first switching valve and the second switching valve being in the first preset state is configured to instruct the drive assembly to evacuate the base station liquid tank; a second control unit, configured to, in response to a drain command, control the first switching valve and the second switching valve to be in a second preset state, and control the drive assembly to operate, so that the base station liquid tank is in a positive pressure state, wherein the first switching valve and the second switching valve being in the second preset state is configured to instruct the drive assembly to pressurize the base station liquid tank.

[0008] According to another aspect of the embodiments of this application, a cleaning device is also provided, including: a device host, a base station, and a control component. The device host includes a host liquid tank, and the base station includes a base station liquid tank, a drive assembly, a first switching valve, and a second switching valve. The control component is configured to, in response to a suction command, control the first switching valve and the second switching valve to be in a first preset state, and control the drive assembly to operate, so that the base station liquid tank is in a negative pressure state. The first switching valve and the second switching valve being in the first preset state is used to instruct the drive assembly to evacuate the base station liquid tank. In response to a drain command, the control component is configured to, control the first switching valve and the second switching valve to be in a second preset state, and control the drive assembly to operate, so that the base station liquid tank is in a positive pressure state. The first switching valve and the second switching valve being in the second preset state is used to instruct the drive assembly to pressurize the base station liquid tank.

[0009] According to another aspect of the embodiments of this application, a computer-readable storage medium is also provided, wherein a computer program is stored in the computer program, and the computer program is configured to execute the test method of the above-described interface at runtime.

[0010] According to another aspect of the embodiments of this application, an electronic device is also provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the test method of the interface described above through the computer program.

[0011] In this embodiment, the positive and negative pressure states of the base station liquid tank are controlled by two switching valves combined with a drive assembly. In response to a suction command, the first and second switching valves are controlled to be in a first preset state, and the drive assembly is controlled to operate, so that the base station liquid tank is in a negative pressure state.

In response to a discharge command, the first and second switching valves are controlled to be in a second preset state, and the drive assembly is controlled to operate, so that the base station liquid tank is in a positive pressure state. The first and second switching valves being in the second preset state... The state is used to instruct the drive component to pressurize the base station liquid tank. By adjusting the state of the base station liquid tank through the state switching of two switching valves, the operation of the drive component can make the base station liquid tank be in a negative pressure state or a positive pressure state. Under negative pressure, the base station liquid tank's ability to draw liquid increases, accelerating the speed at which liquid enters the base station liquid tank from the host liquid tank; while under positive pressure, the base station liquid tank's ability to discharge liquid increases, accelerating the speed at which liquid exits the base station liquid tank. This can achieve the technical effect of improving the self-cleaning efficiency of the cleaning equipment, thereby solving the problem of low self-cleaning efficiency of cleaning equipment control methods in related technologies.

Detailed Implementation Methods

[0043] The present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0044] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0045] According to one aspect of the embodiments of this application, a control method for a cleaning device is provided. Optionally, in this embodiment, the above-described control method for a cleaning device can be applied to, for example... Figure 1 The hardware environment shown consists of terminal device 102, cleaning device 104, and server 106. For example... Figure 1As shown, terminal device 102 can connect to cleaning device 104 and / or server 106 (e.g., IoT platform or cloud server) via a network to control cleaning device 104, such as binding to cleaning device 104 and configuring the cleaning functions of cleaning device 104. Cleaning device 104 may include a device host and a base station (e.g., a sweeper and a base station, a floor scrubber and a base, etc.). The device host and the base station can be connected via a network or via a connection cable or connection interface to interact with the other end, such as determining the current status of the other end (e.g., battery status, working status, location information, etc.) and sending control commands to the other end.

[0046] The aforementioned network may include, but is not limited to, a wireless network. The aforementioned wireless network may include, but is not limited to, at least one of the following: Wi-Fi (Wireless Fidelity), Bluetooth, and infrared. The network used by the terminal device 102 to communicate with the cleaning device 104 and / or the server 106 may be the same as or different from the network used by the cleaning device 104 to communicate with the server 106. The terminal device 102 is not limited to a PC (Personal Computer), mobile phone, tablet computer, etc. The cleaning device 104 may include, but is not limited to, a self-cleaning robot, such as an automatic mop washing machine or floor scrubber. The server 106 may be a server of an Internet of Things (IoT) platform.

[0047] The control method for the cleaning equipment in this embodiment can be executed by the cleaning equipment 104 or by the cleaning equipment in combination with at least some of the terminal equipment 102 and the server 106. Alternatively, the control method can be executed by the cleaning equipment 104 or the terminal equipment 102, or by a client installed on it.

[0048] Taking the cleaning device 104 as an example of executing the control method of the cleaning device in this embodiment, the cleaning device may include a device host and a base station. The device host may include a host liquid tank (e.g., a body wastewater tank, which may be a body wastewater bucket), and may also include other components for achieving surface (e.g., ground or other surfaces) cleaning and self-cleaning, such as cleaning components (which may be roller brushes, mops or other components that can be used for surface cleaning), cleaning component motors (which can be used to drive the cleaning components to rotate), host drive components (e.g., body main motor, etc.), the liquid inlet pipe of the host liquid tank (i.e., the host liquid inlet pipe, for example, the body's suction pipe), the liquid outlet pipe of the host liquid tank (i.e., the host drain pipe, for example, the body's sewage pipe), etc. The base station may include a base station liquid tank (e.g., a base station wastewater tank, which may be a base station wastewater bucket), and may also include other components that work with the main unit to perform surface cleaning or self-cleaning, such as a base station base, a connecting pipe for connecting the main unit liquid tank and the base station liquid tank (e.g., the base station liquid tank inlet pipe, i.e., the base station liquid inlet pipe, which may be a base station sewage suction pipe), a base station liquid tank drain pipe (i.e., the base station drain pipe, e.g., a base station sewage discharge pipe), and so on.

[0049] In related technologies, when the cleaning equipment is performing self-cleaning (or when the cleaning equipment has other cleaning needs), the main unit of the equipment can be connected to the base station. By opening the valve of the drain pipe port (which could be the drain pipe port of the main unit, for example, the sewage pipe port of the main unit) of the main unit's liquid tank, the liquid in the main unit's liquid tank can be transferred to the base station's liquid tank. The base station's liquid tank is usually larger than the main unit's liquid tank, which can improve the efficiency of the cleaning equipment's self-cleaning and prevent the main unit from pausing operation due to a full main unit liquid tank. When the base station's liquid tank is full, the liquid can be manually poured out or drained by opening the valve of the drain pipe port (which could be the drain pipe port of the base station, for example, the sewage pipe port of the base station).

[0050] For example, when discharging sewage, the sewage valve at the bottom of the base station's sewage tank is opened, and the sewage is discharged from the base station's sewage tank by gravity.

[0051] However, the current main unit liquid tank drain port, base station liquid tank inlet port, and base station liquid tank drain port are usually limited in size, which results in a slow liquid transfer speed between the two tanks and a slow drain speed from the base station liquid tank, thus reducing the self-cleaning efficiency of the cleaning equipment.

[0052] To at least partially solve the aforementioned technical problems, in this embodiment, a drive component and two switching valves (i.e., a first switching valve and a second switching valve) can be installed on the base station. The state of the base station liquid tank can be adjusted by switching the states of the two switching valves. Thus, the operation of the drive component can keep the base station liquid tank in a negative pressure state or a positive pressure state. Under negative pressure, the base station liquid tank's ability to draw liquid increases, thereby accelerating the speed at which liquid enters the base station liquid tank from the host liquid tank. Under positive pressure, the base station liquid tank's ability to discharge liquid increases, thereby accelerating the speed at which liquid exits the base station liquid tank. In this way, the self-cleaning efficiency of the cleaning equipment can be improved.

[0053] It should be noted that the cooperation between the two switching valves and the drive components is not limited to the self-cleaning process of the cleaning equipment, but can also be applied to other processes that require the base station liquid tank to handle, as long as the execution of the corresponding process can be guaranteed.

[0054] As an optional approach, Figure 2 This is a flowchart illustrating an optional control method for a cleaning device according to an embodiment of this application, as shown below. Figure 2 As shown, the process of this method may include the following steps:

[0055] In step S202, in response to the liquid suction command, the first switching valve and the second switching valve are controlled to be in a first preset state, and the drive component is controlled to operate so that the base station liquid tank is in a negative pressure state. The first switching valve and the second switching valve being in the first preset state is used to instruct the drive component to evacuate the base station liquid tank.

[0056] The control method for the cleaning equipment in this embodiment can be applied to the self-cleaning process of the cleaning equipment or other processes requiring the base station to absorb or drain liquid. Taking the self-cleaning process as an example, for the base station of the cleaning equipment, in response to the liquid absorption command, the control component on the cleaning equipment can control the first switching valve and the second switching valve to be in a first preset state. Here, the first preset state can be that the first switching valve and the second switching valve are respectively in corresponding designated positions, or that the first switching valve and the second switching valve are in corresponding designated states such as an active state or a fixed state, or that one of the switching valves is in a corresponding designated position and the other is in a corresponding designated state, or it can be other combinations of states.

[0057] Here, if one of the switching valves is already in the corresponding designated position or state, its current position or state can be maintained, while the other switching valve is adjusted to the corresponding designated position or state. If both switching valves are already in the corresponding designated position or state, their current positions or states are maintained, as long as the first and second switching valves are in the first preset state (a combination of the first and second switching valves).

[0058] The first and second switching valves are in a first preset state to instruct the drive assembly to evacuate the base station liquid tank. Before, after, or during the process of controlling the first and second switching valves to be in the first preset state, the drive assembly can be controlled to operate to evacuate the base station liquid tank, thereby placing the base station liquid tank in a negative pressure state. Here, there can be one or more drive assemblies. To evacuate the base station liquid tank, one drive assembly can be controlled to operate while another drive assembly is deactivated, with the operating drive assembly evacuating the base station liquid tank. Optionally, the drive assembly may include a base station main motor, and controlling the base station main motor to operate will evacuate the base station liquid tank.

[0059] Here, when the base station liquid tank is under negative pressure, liquid in the host liquid tank can be drawn into the base station liquid tank through the transmission pipe between the host liquid tank and the base station liquid tank. The transmission pipe may include a host drain pipe (e.g., a body drain pipe) and a base station inlet pipe (e.g., a base station suction pipe). The host drain pipe and the base station inlet pipe may be two separate pipes or the same pipe. The liquid in the host liquid tank may be liquid that has already been drawn into the host liquid tank (in this case, the host liquid tank transfers liquid to the base station liquid tank without drawing liquid into the host liquid tank), or it may be liquid that is being drawn into the host liquid tank in real time (in this case, the host liquid tank transfers liquid to the base station liquid tank while simultaneously drawing liquid into the host liquid tank).

[0060] Optionally, a valve (i.e., a first valve, such as a valve at the bottom of the main unit's liquid tank) can be installed at the drain port at the bottom of the main unit's liquid tank. This valve can remain open throughout the self-cleaning process, or it can be opened when liquid is transferred from the main unit's liquid tank to the base station's liquid tank (this can be achieved by starting the valve opening motor on the base station), and closed at other times. A valve (i.e., a second valve, which can be a wastewater inlet valve or a wastewater inlet valve) can be installed at the inlet of the base station's liquid tank. This valve can be opened when liquid is transferred from the main unit's liquid tank to the base station's liquid tank, and closed at other times. The valve can be controlled by a lever or other components, or by the positive or negative pressure of the base station's liquid tank. In this case, the valve can be an inlet flap (e.g., a wastewater inlet flap).

[0061] It should be noted that the liquid aspiration command is a liquid aspiration command for the base station's liquid tank, which can be automatically generated by the control components on the cleaning equipment or manually triggered. The control components on the cleaning equipment can be located on the equipment host, on the base station, or partially on the equipment host and partially on the base station. This embodiment does not impose any limitations on this.

[0062] Step S204: In response to the drain command, control the first switching valve and the second switching valve to be in a second preset state, and control the drive component to operate so that the base station liquid tank is in a positive pressure state. The first switching valve and the second switching valve being in the second preset state is used to instruct the drive component to pressurize the base station liquid tank.

[0063] After the liquid aspiration termination conditions are met (e.g., the liquid aspiration time reaches a specified duration, the host liquid tank is empty, the base station liquid tank is full, etc.), a drain command can be generated; alternatively, the drain command can be manually triggered. In response to the liquid aspiration command, the control unit on the cleaning equipment can control the first and second switching valves to a second preset state. This second preset state can be that the first and second switching valves are each in a corresponding specified position, or that the first and second switching valves are in a movable state, a fixed state, or other corresponding specified states, or that one switching valve is in a corresponding specified position and the other is in a corresponding specified state, or other combinations of states.

[0064] Here, if one of the switching valves is already in the corresponding designated position or state, its current position or state can be maintained, while the other switching valve is adjusted to the corresponding designated position or state. If both switching valves are already in the corresponding designated position or state, their current positions or states can be maintained, as long as the first and second switching valves are in the second preset state (a combination of the first and second switching valves).

[0065] The first and second switching valves are in a second preset state to instruct the drive assembly to pressurize the base station liquid tank. Before, after, or during the process of controlling the first and second switching valves to be in the second preset state, the drive assembly can be controlled to operate to pressurize the base station liquid tank, thereby placing the base station liquid tank under positive pressure. Here, there can be one or more drive assemblies. To pressurize the base station liquid tank, one drive assembly can be controlled to operate while another drive assembly is deactivated, with the operating drive assembly pressurizing the base station liquid tank.

[0066] Here, when the base station liquid tank is under positive pressure, the liquid in the base station liquid tank can be discharged through the drain port at the bottom of the main unit liquid tank. Optionally, a valve (i.e., the aforementioned second valve) can be installed at the liquid inlet of the base station liquid tank. This valve is closed when the base station liquid tank is under positive pressure and is opened at certain designated times. A valve (i.e., a third valve) can be installed at the drain port at the bottom of the base station liquid tank. This valve is opened when the base station liquid tank is under positive pressure and closed at other times. The opening or closing of this valve can be controlled by a lever or other components. In this case, the valve can be a drain baffle (e.g., a sewage baffle).

[0067] For example, the base station wastewater tank is equipped with an inlet valve and a bottom drain valve, which provides a negative pressure environment when suctioning wastewater, temporarily storing the dirt in the base station wastewater tank; and then opens the bottom drain valve to discharge the dirt when draining wastewater under positive pressure.

[0068] Through steps S202 to S204 above, in response to the liquid suction command, the first switching valve and the second switching valve are controlled to be in a first preset state, and the drive component is controlled to operate, so that the base station liquid tank is in a negative pressure state. The first switching valve and the second switching valve being in the first preset state is used to instruct the drive component to evacuate the base station liquid tank. In response to the liquid discharge command, the first switching valve and the second switching valve are controlled to be in a second preset state, and the drive component is controlled to operate, so that the base station liquid tank is in a positive pressure state. The first switching valve and the second switching valve being in the second preset state is used to instruct the drive component to pressurize the base station liquid tank. This solves the problem of low self-cleaning efficiency of cleaning equipment in the control methods of cleaning equipment in related technologies, and improves the self-cleaning efficiency of cleaning equipment.

[0069] In one exemplary embodiment, the aforementioned driving component may include a suction motor (which may be the base station main motor) for evacuating and pressurizing the base station liquid tank. The base station may also include a switching power source for controlling the switching of the states of the first switching valve and the second switching valve. The component driving the first and second switching valves to switch states may be a drive slider. The switching power source, drive slider, first switching valve, and second switching valve may all belong to a motor assembly (e.g., a sewage discharge motor assembly). This motor assembly may be a new component added to the base station (e.g., a...). Figure 3 As shown), the first switching valve can be a switching valve for the drive component that switches the suction gas, and it can be an upper switching valve. The second switching valve can be a switching valve that works in conjunction with the air port that switches the suction gas, and it can be a lower switching valve.

[0070] For example, such as Figure 4 As shown, the motor assembly has a switchable airflow structure (i.e., a switching duct) containing two rotatable upper and lower switching valves (the two switching valves are located in...). Figure 4 The motor assembly includes the internal components (as shown), a switching power source for rotating the two switching valves, and a drive slider (which can be combined with gears or other structures to rotate the switching valves). Additionally, the motor assembly may include a suction motor (e.g., a base station main motor), which can provide both negative pressure suction and positive pressure discharge functions.

[0071] Optionally, the base station also includes a ventilation duct, which can be an internal air passage structure of the aforementioned motor assembly. The ventilation duct can be switched by changing the state of the first switching valve and the second switching valve. The ventilation duct includes an intake port and an exhaust port. The intake port can be the air port used by the drive assembly to draw air from the base station liquid tank through the ventilation duct. It can be located on one side of the ventilation duct and on the side where the drive assembly draws in gas. The exhaust port is the air port for discharging the gas drawn from the base station liquid tank. This exhaust port can be the exhaust port when drawing air from the base station liquid tank and can be located on the side where the drive assembly discharges gas.

[0072] For example, when switching power sources, the upper and lower switching valves can rotate 90 degrees to switch positions, thus switching the air duct. The inlet and outlet positions before switching are as follows: Figure 5 As shown, at this time, the air outlet is the exhaust port, and the air inlet is the inlet of the suction pipe (e.g., suction hose) connecting the motor assembly and the base station wastewater tank. At this time, the upper switching valve is roughly horizontally upward. Since the air inlet is not blocked, the suction pipe is connected to the air duct on the upper side of the base station main motor, allowing air to be drawn in from the upper side of the base station main motor. The lower switching valve is also roughly horizontally upward, connecting the air duct from the lower side of the base station main motor to the exhaust port, allowing gas discharged from the lower side of the base station main motor to be discharged through the exhaust port. The air inlet position when the motor assembly and the base station wastewater tank are working together for suction is as follows: Figure 6 As shown, Figure 6 The air intake position is the connection port between the base station's suction pipe and the host's discharge pipe.

[0073] Correspondingly, in response to the liquid aspiration command, the first switching valve and the second switching valve are controlled to be in a first preset state, and the drive component is controlled to operate, so that the base station liquid tank is in a negative pressure state, including:

[0074] S11, in response to the liquid suction command, control the first switching valve to the first position to open the suction port, and control the second switching valve to the second position to open the exhaust port;

[0075] S12, the control drive component draws air through the air intake to put the base station liquid tank in a negative pressure state, wherein the gas drawn from the base station liquid tank is discharged from the exhaust port through the air duct.

[0076] In response to a suction command, the first switching valve can be controlled to a first position (e.g., Figure 5 The upper switching valve is in the horizontal-upward position to open the intake port, controlling the second switching valve to the second position (e.g., ...). Figure 5 (The middle and lower switching valve is in the horizontal upward position) to open the exhaust port. Here, when the first switching valve and the second switching valve are in the first preset state, the first switching valve is in the first position and the second switching valve is in the second position.

[0077] When the first switching valve and the second switching valve are in the first preset state, the drive component can be controlled to draw air through the air intake port. The gas drawn from the base station liquid tank is discharged from the exhaust port through the air duct. At this time, the base station liquid tank is in a negative pressure state. The drive component drawing air through the air intake port can be achieved by a suction motor drawing air through the air intake port.

[0078] For example, combining Figure 5 and Figure 6Under the action of switching power sources, the drive slider is driven upward, and the upper and lower switching valves move to the desired positions under the drive slider's influence. Figure 4 As shown, the air duct is placed under negative pressure, and then the suction motor operates, causing the airflow within the entire assembly to be as follows: Figure 6 As shown, the base station's wastewater tank is placed under negative pressure, causing the dirt inside the wastewater tank of the floor scrubber to be drawn out. Figure 6 The air is drawn into the base station's wastewater tank through the air intake.

[0079] In this embodiment, the air duct is switched by adjusting the position of the switching valve to form an air path that can draw air from the base station liquid tank, which can improve the convenience of air path switching.

[0080] In an exemplary embodiment, the air duct may further include an air inlet, which may be an air inlet used by the drive component to pressurize the base station liquid tank through the air duct. The air inlet and the air intake may be located on the same side of the drive component, for example, both located on the side of the drive component that receives the gas.

[0081] For example, under the action of switching power sources, the upper and lower switching valves can rotate 90 degrees to switch positions, thereby switching the air duct. The inlet and outlet positions after switching are as follows: Figure 7 As shown, Figure 7 The air inlet is the air supply port, and the air outlet is the pipe opening of the suction pipe connecting the motor assembly and the base station wastewater tank. At this time, the upper switching valve is roughly in a vertically downward position. Because the air inlet is blocked and the air supply port is open, the suction pipe is not connected to the air duct on the upper side of the base station main motor, allowing air to be drawn in from the upper side of the base station main motor through the air supply port. The lower switching valve is also roughly in a vertically downward position. The air duct from the lower side of the base station main motor to the exhaust port is not connected, but the air duct from the lower side of the base station main motor to the suction pipe is connected. The gas discharged from the lower side of the base station main motor can enter the base station liquid tank through the exhaust pipe, pressurizing the base station liquid tank. The air outlet position when the motor assembly and the base station wastewater tank are used for wastewater discharge is as follows: Figure 8 As shown, Figure 8 The vent in the middle is the sewage outlet of the base station's sewage tank, which can be connected to the sewer.

[0082] Correspondingly, in response to the drain command, the first switching valve and the second switching valve are controlled to be in a second preset state, and the drive component is controlled to operate, so that the base station liquid tank is in a positive pressure state, including:

[0083] S21, in response to the drain command, control the first switching valve to the third position to open the air supply port while blocking the air intake port, and control the second switching valve to the fourth position to block the exhaust port;

[0084] S22, the control drive component delivers air through the air inlet to put the base station in a positive pressure state, wherein the gas delivered to the base station liquid tank enters the base station liquid tank through the air duct.

[0085] In response to the drain command, the first switching valve can be controlled to the third position to open the air supply port while blocking the air intake port, and the second switching valve can be controlled to the fourth position to block the exhaust port. Here, when the first switching valve and the second switching valve are in the second preset state, the first switching valve is in the third position and the second switching valve is in the fourth position.

[0086] When the first switching valve and the second switching valve are in the second preset state, the drive component can be controlled to deliver gas through the gas outlet. The gas delivered to the base station liquid tank enters the base station liquid tank through the air duct. At this time, the base station liquid tank is in a positive pressure state.

[0087] For example, when the sewage tank of a base station is being discharged, the drive slider moves downward under the action of the switching power source. The upper and lower switching valves, driven by the drive slider, move to a position similar to... Figure 9 The position shown puts the air duct in a positive pressure drainage state, and the overall air path is as follows: Figure 8 As shown, under the action of the suction motor, pressure is applied to the sewage tank of the base station, so that the sewage in the sewage tank is discharged into the sewer, thus completing the sewage discharge.

[0088] In this embodiment, the air duct is switched by adjusting the position of the switching valve to form an air path that can deliver air into the base station liquid tank, which can improve the convenience of air path switching.

[0089] In an exemplary embodiment, to ensure the cleanliness of the base station liquid tank, an ozone sterilization structure can be provided. This ozone sterilization structure may include an ozone generator located at the air inlet, which generates ozone, and ozone has sterilization capabilities. For example... Figure 10 As shown, the motor assembly may include: two switching valves (i.e., a first switching valve and a second switching valve), an ozone generator, a base station main motor, and a switching motor (i.e., a switching power source).

[0090] Correspondingly, after controlling the first switching valve and the second switching valve to be in a second preset state and controlling the drive component to operate so that the base station liquid tank is in a positive pressure state, the above method further includes:

[0091] S31, in response to the sterilization command, controls the ozone generator to generate ozone and controls the drive component to operate in order to sterilize the base station liquid tank, wherein the ozone generated by the ozone generator is sent into the base station liquid tank through the air duct.

[0092] To sterilize the base station liquid tank, in response to a sterilization command, the control unit can control an ozone generator to produce ozone. This sterilization command can be generated automatically during the self-cleaning process or manually triggered. Simultaneously, a drive component can be controlled to operate. This drive component can have a blowing function to deliver the ozone generated by the ozone generator into the base station liquid tank via an air duct, thereby sterilizing the tank. In sterilization mode, the operating drive component can be an ozone delivery fan.

[0093] For example, such as Figure 11 As shown, the base station is equipped with a base station wastewater tank, a motor assembly, and a sewage discharge pipeline. The motor assembly also includes an ozone sterilization component, comprising an ozone generator and an ozone delivery fan. With the above functions, after the floor scrubber's base station automatically discharges wastewater, the motor assembly, under the action of switching power sources, switches the air duct structure to the ozone sterilization air path. The ozone generator on the motor assembly operates, producing ozone. The ozone delivery fan blows the generated ozone into the air duct of the motor assembly, and then transports it along the pipeline to the base station wastewater tank, finally... Figure 8 The sewage outlet shown (i.e., the vent) discharges the sewage, achieving sterilization and deodorization of the inside of the pipeline and the sewage tank of the base station.

[0094] In this embodiment, by adding an ozone sterilization module and coordinating with the pipeline switching structure of the motor assembly, the sterilization and deodorization function of the base station liquid tank pipeline is achieved, preventing the base station liquid tank and pipeline from generating odors and affecting the user experience.

[0095] In one exemplary embodiment, solids mixed in with the liquid drawn into the base station's liquid tank may jam the valves (e.g., inlet flaps, drain baffles, etc.) on the pipeline from the base station's suction pipe to its drain pipe, thereby affecting the use of the components and the self-cleaning process. To address this, a solid-liquid separation structure can be provided on the base station to filter the solids mixed in with the liquid entering the base station's liquid tank. This solid-liquid separation structure may include a filter screen (e.g., a disposable filter screen), and a guide groove for inserting the filter screen can be provided on the base station. Optionally, the filter screen inserted into the guide groove can be located at the inlet valve (e.g., the aforementioned inlet flap) of the base station's liquid inlet pipe, and it may include a rigid frame and a filter screen body.

[0096] For example, such as Figure 12As shown, users can choose to install a disposable filter (i.e., an optional disposable filter, such as a nylon filter) based on their household solid waste situation to separate solids and liquids in wastewater. Solid waste remains inside the filter, while liquid waste is discharged into the sewer. The disposable filter can consist of a rigid frame and a filter screen. Users can place the disposable filter into the guide groove on the base station's wastewater tank, slide it downwards, and insert it until it reaches the bend position to complete the installation. This assembly method allows the disposable filter to be fully opened in the space. When wastewater is drawn in, the inlet flap is opened, such as... Figure 13 As shown, the exhaust pipe of the base station draws air, creating a negative pressure state inside the base station's sewage tank. The sewage inlet flap opens under negative pressure, allowing the solid-liquid mixture of dirt to enter the base station's sewage tank. After being filtered by the filter screen, the sewage is temporarily stored inside the base station's sewage tank. Once the sewage in the unit is emptied, the base station's exhaust pipe switches from drawing air to filling air, creating a positive pressure inside the base station's sewage tank. Liquid dirt is discharged from the base station's sewage tank through the sewage discharge structure and discharged into sewers or other locations, while solid waste is temporarily stored in the filter screen structure.

[0097] As an optional implementation, the sterilization command can be generated upon detecting that a filter screen is inserted into the guide channel. Correspondingly, the above method further includes:

[0098] S41, the filter screen inserted in the guide groove is detected by the filter screen in place corresponding to the filter screen inserted in the guide groove, and the filter screen detection result is obtained;

[0099] S42, when the filter detection result is used to indicate that a filter is inserted in the guide groove, a sterilization command is generated.

[0100] To determine whether sterilization of the base station liquid tank is necessary, a filter presence detection component corresponding to the filter inserted in the guide channel can be used to detect the filter's presence and obtain the filter detection result. This filter presence detection component can be a Hall effect sensor, such as a Hall sensor board. When the filter detection result indicates that a filter is inserted in the guide channel, a sterilization command can be generated at an appropriate time.

[0101] Here, the timing for in-situ detection of the filter screen inserted in the guide groove can be after controlling the first and second switching valves to be in the second preset state and controlling the drive component to run, or after the self-cleaning process ends (e.g., after the cleaning component is dried), or other detection timings; the timing for generating the sterilization command can be after the base station liquid tank is drained, after the self-cleaning process ends, or other timings. This embodiment does not limit this.

[0102] For example, when the program detects through the filter presence Hall effect that the user has installed a filter but not removed it after self-cleaning, it activates the ozone module. Ozone is generated and enters the tank through a suction pipe (e.g., a suction hose). At this time, the inside of the tank is sealed, and the ozone is used to sterilize solid waste and the entire wastewater tank. Furthermore, when the user observes that the filter is full or the timer has expired, they can remove and discard the filter and install a new one, without requiring secondary emptying or cleaning.

[0103] As another optional implementation, a sterilization command is generated regardless of whether a filter screen is inserted in the guide channel. The presence or absence of a filter screen affects the ozone generation parameter in the sterilization command. Correspondingly, a similar method can be used to detect the presence of the filter screen inserted in the guide channel using a filter screen presence detection component corresponding to the filter screen inserted in the guide channel, obtaining the filter screen detection result. After obtaining the filter screen detection result, the above method further includes:

[0104] S43, when the filter detection result is used to indicate that a filter is inserted in the guide groove, a sterilization command is generated to instruct the ozone generator to produce ozone according to the first ozone production parameters.

[0105] S44, when the filter detection result indicates that no filter is inserted in the guide groove, a sterilization command is generated to instruct the ozone generator to produce ozone according to the second ozone production parameters.

[0106] When the filter detection result indicates that a filter is inserted in the guide groove, the ozone generation parameter indicated by the generated sterilization command is the first ozone generation parameter. At this time, the sterilization command is used to instruct the ozone generator to generate ozone according to the first ozone generation parameter. When the filter detection result indicates that no filter is inserted in the guide groove, the ozone generation parameter indicated by the generated sterilization command is the second ozone generation parameter. At this time, the sterilization command is used to instruct the ozone generator to generate ozone according to the second ozone generation parameter. Here, the first ozone generation parameter and the second ozone generation parameter can be pre-configured different ozone generation parameters (the parameter types can be the same, or the parameter values ​​of the same parameter type can be different). The concentration of ozone generated according to the first ozone generation parameter is higher than the concentration of ozone generated according to the second ozone generation parameter.

[0107] Here, the ozone generation parameters on which the ozone generator produces ozone may include one or more, including but not limited to: the working time of the ozone generator. The first ozone generation parameter and the second ozone generation parameter may both include the working time of the ozone generator, wherein the working time in the first ozone generation parameter is greater than the working time in the second ozone generation parameter.

[0108] For example, the combination of ozone sterilization module and disposable filter can be configured as follows: Figure 14As shown, a structure for treating solid waste can be formed by combining a disposable filter, an ozone generating module, a water sprayer, and a base station wastewater tank. Here, a water sprayer can be installed inside the base station's wastewater tank (e.g., Figure 14 The sprayer shown can be used to spray liquid onto the inner wall of the base station's liquid tank, thus cleaning the tank. The deodorization effect of the base station's wastewater tank is determined by the ozone concentration and the contact time. The ozone concentration can be controlled by adjusting the working time of the ozone generator; a longer working time results in a higher ozone concentration, a longer ozone sterilization time, and a better deodorization effect.

[0109] An example application is as follows: When the base station's wastewater tank is not equipped with a disposable filter, the tank is empty after one wastewater discharge, leaving no residue. Therefore, the required concentration for sterilization and deodorization is low. When a disposable filter is installed, solid waste is filtered and temporarily stored in the tank after discharge. In this case, a higher concentration of sterilization is needed to prevent odors. Therefore, sensors can be installed to identify whether the base station has a disposable filter. If a filter is installed, the ozone module's operating time is increased to raise the ozone concentration; conversely, the operating time can be shortened to control the ozone concentration.

[0110] In addition, feedback devices such as odor sensors can be added to control the ozone generator based on the feedback results from the odor sensors in the base station's wastewater tank. Specifically, the odor detection results from the odor sensors in the base station's tank are acquired. At the odor concentration indicated by the detection results, a sterilization command is generated. This command instructs the ozone generator to produce ozone according to ozone generation parameters that match the odor concentration indicated by the detection results. Here, the odor concentration is positively correlated with the concentration of ozone produced according to the matched ozone generation parameters.

[0111] When the floor scrubber is working, the suction pipe is activated, and the wastewater tank of the base station is under negative pressure. Solid and liquid mixed dirt enters the wastewater tank of the base station through the base station inlet pipe. Large particles of solid waste are filtered through a disposable filter and temporarily stored in the disposable filter. Liquid dirt is discharged through the base station outlet pipe.

[0112] This embodiment allows for the determination of whether to perform sterilization treatment on the base station liquid tank based on whether a filter screen is inserted in the guide channel, or by controlling the ozone concentration used for sterilization treatment, thereby improving the flexibility of sterilization control.

[0113] In one exemplary embodiment, when the filter detection result is used to indicate that a filter is inserted in the guide groove, the above method further includes:

[0114] S51, if it is detected that the filter screen inserted in the guide groove has not been removed within a first preset time period after being used, a first prompt message is issued by the cleaning device, wherein the first prompt message is used to prompt the replacement of the filter screen inserted in the guide groove.

[0115] If the filter detection result indicates that a filter is inserted in the guide channel, excessive dirt will accumulate on the filter if it is not replaced for a long time, leading to a decrease in filtration efficiency. To address this, the duration for which the filter remains inserted in the guide channel after it has been used can be monitored. This monitoring can be continuous, performed during each self-cleaning cycle, or at other times. The duration can be the time difference between when the filter was first detected as being used and the time when the filter was last detected in the guide channel.

[0116] If the filter inserted in the guide channel is not removed within a first preset time period after use (e.g., one week, half a month, etc., which can be flexibly configured as needed), the cleaning device can issue a first prompt message to remind the user to replace the filter inserted in the guide channel. The prompt may be made in a manner including but not limited to at least one of the following: voice prompt, text prompt (displayed on the display screen), or visual prompt (displayed on the display screen).

[0117] Here, the use of the filter inserted in the guide channel can be determined based on the detection of the filter inserted in the guide channel during the self-cleaning process. That is, if the filter inserted in the guide channel is detected during the self-cleaning process, it can be determined that the filter inserted in the guide channel is being used.

[0118] For example, if the program detects that the user has not removed the filter for a week, the machine (e.g., the main unit of a floor scrubber) will alarm to remind the user to replace the filter.

[0119] This embodiment detects that the filter inserted in the guide groove has not been removed within a certain period of time after use, prompting a replacement filter. This reduces the likelihood of excessive dirt on the filter causing a decrease in filtration efficiency and improves the user experience.

[0120] In one exemplary embodiment, considering that the filter is inserted into the guide groove, and that the filter itself has many holes, the difficulty of in-situ detection is increased. To address this, the base station can also be equipped with a rotating magnet bracket. The filter inserted into the guide groove drives the rotating magnet bracket to rotate to a designated position, and the filter in-situ detection component can be used to detect the in-situ status of the filter inserted into the guide groove by whether the rotating magnet bracket has been detected to the designated position.

[0121] For example, the aforementioned solid-liquid separation structure may include: a disposable filter screen, a sludge inlet flap, a rotating magnet support, and a Hall effect detection plate, such as... Figure 15As shown. After the disposable filter is installed, it will cause the rotating magnet bracket to rotate. The Hall effect sensor board will detect that the user has installed the disposable filter. After the first self-cleaning, the main control program will start timing. If the user does not remove the filter within a certain period of time (e.g., 1 week), the machine will alarm to remind the user to replace the filter.

[0122] In this embodiment, the in-situ detection of the filter inserted in the guide groove is improved by detecting whether the rotating magnet bracket rotated to a specified position is detected by the filter in-situ detection component.

[0123] In an exemplary embodiment, the base station may further include a drive slider and a drain baffle disposed at the drain port of the base station liquid tank. The drive slider and drain baffle are similar to those described above and will not be repeated here. Here, the drain baffle may be a drain valve of the base station liquid tank, for example, a sewage valve at the bottom of the base station wastewater tank. Furthermore, the base station may also include a lever (e.g., a valve lever) corresponding to the drain baffle. Here, the lever can adjust the open and closed state of the drain baffle.

[0124] Correspondingly, in response to the drain command, the first switching valve and the second switching valve are controlled to be in a second preset state, and the drive component is controlled to operate, so that the base station liquid tank is in a positive pressure state, including:

[0125] S61, in response to the drain command, controls the drive slider to drive the first switching valve and the second switching valve to the second preset state, and drives the lever to open the drain baffle to the specified angle.

[0126] In response to the drain command, the drive slider can be controlled to drive the first switching valve and the second switching valve to the second preset state. At the same time, the drive slider can also drive the lever to open the drain baffle to a specified angle, thereby opening the base station drain pipe so that the liquid in the base station tank can be discharged through the base station drain pipe.

[0127] For example, the motor assembly and the base station's wastewater tank are interconnected, such as... Figure 9 As shown, when discharging sewage from the base station's wastewater tank, the motor assembly switches power sources, driving the slider downwards. The upper and lower switching valves, driven by the slider, move to the desired position. Figure 7 At the indicated position, simultaneously driving the slider downwards to push the valve lever will open the sewage discharge valve at the bottom of the base station's sewage tank.

[0128] For example, after the wastewater in the base station is drained, the exhaust pipe switches from suction to inflation, and the wastewater discharge baffle opens under the drive of a motor. Figure 16As shown, the motor (i.e., the aforementioned switching power source) drives the motor slider (i.e., the aforementioned drive slider) to press down the lever (i.e., the aforementioned valve lever), causing the sewage discharge baffle to open to approximately 90°. The sewage inlet flap closes under positive pressure, at which point the base station sewage tank is under positive pressure, and the valve at the bottom of the base station sewage tank (i.e., the sewage discharge baffle, as shown) is closed. Figure 17 As shown, the valve opens, allowing sewage and solid particles to be quickly flushed out of the base station's sewage tank, preventing blockages. Sewage is then discharged from the base station's drain pipe into the sewer. Afterward, the motor resets, and the drain baffle closes (a micro switch is located on the lever on the side of the drain baffle to detect when the drain baffle closes and resets. If, under certain extreme conditions, dirt jams the drain baffle, the self-cleaning process stops, reminding the user that the valve is jammed and manual cleaning is required), thus completing a sewage discharge process.

[0129] Here, the operation control of the motor assembly during ozone sterilization of the base station wastewater tank is similar to that during wastewater discharge. Specifically, during ozone sterilization, the power source is switched, driving the slider downwards. Simultaneously, the upper and lower switching valves, driven by the slider, push the valve lever downwards, opening the discharge valve at the bottom of the base station wastewater tank and creating an ozone sterilization gas path.

[0130] In this embodiment, by driving the slider to drive the lever to open the drain baffle to a specified angle, the liquid in the base station liquid tank can be discharged through the corresponding pipeline, which can improve the convenience of draining the base station liquid tank.

[0131] In an exemplary embodiment, to clean the base station liquid tank, a tank cover, a sprayer (e.g., a water sprayer), and a nozzle can be provided on the base station. Here, the tank cover can be a movable structure, i.e., it can be opened and closed; it can be an automatically closing structure or a non-automatically closing structure. The sprayer can be designed to spray water downwards or at an angle downwards, rinsing the inner wall of the base station liquid tank. The nozzle can be designed to spray water upwards or at an angle upwards, rinsing the tank cover of the base station liquid tank. Its structure can be as follows: Figure 18 As shown.

[0132] Correspondingly, after controlling the first switching valve and the second switching valve to be in the second preset state and controlling the drive component to operate so that the base station liquid tank is in a positive pressure state, the above method further includes:

[0133] S71, in response to a cleaning command, controls the sprayer to spray liquid onto the inner wall of the base station liquid tank to clean the inner wall of the base station liquid tank, and controls the nozzle to spray liquid onto the liquid tank cover to clean the liquid tank cover.

[0134] After responding to the drain command and controlling the base station liquid tank to a positive pressure state, the base station liquid tank can be cleaned (i.e., the base station liquid tank cleaning process is executed, such as the base station wastewater tank drain cleaning process). In this case, a cleaning command can be automatically generated (or the base station liquid tank cleaning process can be executed separately, in which case the cleaning command can be manually triggered). In response to the cleaning command, the sprayer can be controlled to spray liquid onto the inner wall of the base station liquid tank to clean the inner wall of the base station liquid tank, and the nozzle can be controlled to spray liquid onto the liquid tank cover to clean the liquid tank cover.

[0135] For example, after the sewage discharge process is completed, the machine can start a self-cleaning process (base station sewage tank sewage discharge and cleaning process). The cleaning water pump (i.e., the base station water pump) is started, and water enters the sprayer and nozzle through two pipes respectively. The sprayer sprays water downward to spray and clean the inner wall of the base station sewage tank, and the nozzle sprays water upward to spray and clean the cover of the base station sewage tank.

[0136] In this embodiment, the cleanliness of the base station liquid tank can be ensured and its service life can be improved by using a sprayer and a nozzle to rinse the inner wall and the tank cover.

[0137] In an exemplary embodiment, the base station liquid tank may be equipped with solid-liquid-vapor separation measures. For example, the base station may further include: a liquid inlet flap disposed at the liquid inlet of the base station liquid tank and a water vapor separation baffle disposed after the liquid inlet flap. The design of the liquid inlet flap is similar to that in the previous embodiment, while the water vapor separation baffle may be disposed after the liquid inlet flap to separate the water vapor mixture entering the base station liquid tank through the liquid inlet flap.

[0138] In this embodiment, the base station may further include an exhaust pipe, the design of which is similar to that in the previous embodiment, and a filter screen is provided at the connection between the exhaust pipe and the base station liquid tank (i.e., the exhaust port) to at least partially block solids from entering the base station motor through the exhaust pipe.

[0139] For example, such as Figure 19 As shown, when the base station motor is pumping air, solid and liquid waste is blocked by the water vapor separation baffle. Through the structure, the water vapor is pushed downwards and falls into the lower part of the base station sewage tank. At the same time, the exhaust port is equipped with a filter screen to prevent a small part of solid waste from entering the pumping motor (i.e., the base station motor).

[0140] In this embodiment, by installing a water vapor separation baffle inside the base station, the water vapor mixture entering the base station liquid tank can be separated, preventing water vapor from entering the suction motor and other components and affecting their service life. By installing a filter screen at the exhaust port, the risk of solid waste entering the suction motor can be reduced, preventing solid waste from entering the suction motor and other components and affecting their service life.

[0141] In one exemplary embodiment, the device host also includes a host motor, a cleaning component, and a cleaning component motor. The base station also includes a base station base, a cleaning tank on the base station base, and a liquid outlet on the base station base. Water is stored in the cleaning tank through the liquid outlet on the base station base to perform self-cleaning of the cleaning component.

[0142] For example, such as Figure 20 As shown, the body of the floor scrubber (i.e., the main unit of the equipment) includes the main motor of the body, the wastewater tank of the body, the inlet channel (i.e., the suction pipe) and the outlet channel (i.e., the outlet pipe), while the base station is equipped with a base station motor assembly (i.e., the aforementioned motor assembly) and a base station base, and a cleaning tank is provided on the base station base.

[0143] Correspondingly, before responding to the liquid aspiration command, controlling the first switching valve and the second switching valve to be in a first preset state, and controlling the drive component to operate so that the base station liquid tank is in a negative pressure state, the above method further includes:

[0144] S81, in response to the self-cleaning start signal, controls the cleaning equipment to enter the self-cleaning mode;

[0145] S82, in self-cleaning mode, the following self-cleaning operation is performed on the cleaning part a specified number of times:

[0146] After a specified amount of liquid is added to the cleaning tank through the liquid outlet on the base station base, the cleaning component is rotated by the cleaning component motor to perform self-cleaning.

[0147] When self-cleaning is required, a self-cleaning start signal can be generated via the self-cleaning button on the cleaning device, the corresponding button on the remote control paired with the cleaning device, the corresponding button on the operating interface of the terminal device bound to the cleaning device, or other methods. In response to the self-cleaning start signal generated by the device itself or received from the paired remote control or the bound terminal device, the cleaning device can enter self-cleaning mode. Before entering self-cleaning mode, it can first check whether the device host and the base station are connected. If not connected, it will prompt the user to place the device host on the base station base to connect the device host to the base station; if connected, it can enter self-cleaning mode. In addition, other preconditions for entering self-cleaning mode can be set to improve the reliability and security of self-cleaning execution.

[0148] In self-cleaning mode, the cleaning component can be cleaned first. This cleaning can be done by repeatedly performing a specified number of self-cleaning operations on the component, for example, performing n self-cleaning operations, where n is a positive integer greater than or equal to 1. Here, the self-cleaning operation can be as follows: after filling the cleaning tank with a specified amount of liquid through the outlet on the base station base, the cleaning component's motor controls its rotation to perform self-cleaning.

[0149] Here, after each self-cleaning operation is completed, under the negative pressure drive of the activated main motor (e.g., the main motor of the machine body), the liquid that has cleaned the cleaning parts is drawn into the main liquid tank through the main liquid suction pipe. When the liquid tank is full or when a specified number of self-cleaning operations have been completed, a suction command is generated. Here, the suction command can be generated during the aforementioned water tank and pipeline cleaning process.

[0150] Optionally, when it is detected that the device host is placed on the base station and the liquid in the clean water tank on the device host is not full, the following water replenishment process can be executed: the base station water pump runs, pumping the liquid in the base station into the clean water tank on the device host (e.g., the clean water tank on the device body). If the water replenishment process is not completed before the entire machine cleans the roller brush after the self-cleaning button is activated, the water replenishment process can continue without interrupting the process.

[0151] Optionally, in response to a self-cleaning start signal, the cleaning device is controlled to enter a self-cleaning mode, wherein the self-cleaning mode is a mode in which the cleaning device performs a self-cleaning process, and the self-cleaning process may include at least one of the following cleaning processes having an execution order:

[0152] The self-cleaning process of the cleaning component involves performing the self-cleaning operation of the cleaning component n times in a loop. After each self-cleaning operation is completed, the liquid that has been cleaned is drawn into the liquid tank of the main unit through the liquid suction pipe of the main unit under the negative pressure drive of the started main unit motor. n is a positive integer greater than or equal to 1.

[0153] The host liquid draining process involves the base station liquid tank being under negative pressure (this can be controlled by the aforementioned suction command), and the liquid in the host liquid tank being drawn into the base station liquid tank through the host drain pipe and the base station inlet pipe.

[0154] The water tank pipeline cleaning process involves the base station liquid tank being under negative pressure (this can be controlled by the aforementioned suction command), and the drain pipeline from the host suction pipe to the base station liquid tank being cleaned.

[0155] The base station drainage cleaning process involves the base station being under positive pressure (the base station liquid tank can be controlled to be under negative pressure via the aforementioned drainage command), the base station liquid tank and base station drainage pipe being cleaned, and the liquid in the base station liquid tank being discharged through the base station drainage pipe.

[0156] Here, regarding the cleaning process of the water tank pipeline, the relevant technology for cleaning the wastewater tank of the device is as follows: a nozzle is inserted from the base station into the wastewater tank of the device, and water is sprayed obliquely upwards into the interior by a high-pressure water pump. The above method requires the retention of a water vapor separation baffle in the wastewater tank of the device, resulting in sanitary dead corners that cannot be cleaned; the water spray direction is upward and the water flow direction is downward, resulting in poor cleaning effect; the washed-down debris or hair will get stuck on the nozzle rod; the sprayed water may enter the upper suction port of the wastewater tank, causing water to enter the main motor of the device.

[0157] The cleaning process using the water tank pipeline described above eliminates the need for nozzles inserted from the base station into the wastewater tank of the fuselage, thus improving both the cleaning effect and the safety of the main motor of the fuselage.

[0158] Optionally, during the water tank and pipeline cleaning process, after a specified amount of water is added to the cleaning tank through the outlet on the base station base, the cleaning component is rotated by the cleaning component motor, and the drive component is operated (e.g., the base station motor is started), and the cleaning component motor is started; wherein, during the water tank and pipeline cleaning process, under the negative pressure drive of the base station motor, the liquid in the cleaning tank is drawn into the base station liquid tank through the cleaned cleaning component, the host suction pipe, the host liquid tank, the host drain pipe, and the base station inlet pipe, so as to clean the drain pipe.

[0159] Optionally, such as Figure 21 and Figure 22 As shown, the main unit of the equipment also includes a rotating component (e.g., a separator impeller) located inside the main unit liquid tank and a rotating component motor (e.g., a separator motor) connected to the rotating component. The cross-section of the upper outlet of the suction pipe corresponds to the axial position of the rotating component, so that the gas-liquid mixture sucked into the main unit liquid tank through the main unit suction pipe is separated into water and gas. At the same time, at least a portion of the liquid sucked into the main unit liquid tank through the main unit suction pipe is dispersed by the rotating component on the rotating component and impacts the inner wall of the main unit liquid tank to clean the inner wall of the main unit liquid tank.

[0160] Optionally, the rotating component includes arc-shaped blades. Liquid drawn into the host liquid tank through the suction pipe passes through the bottom of the rotating component. A portion of the liquid is rotated and thrown to the side by the bottom of the rotating component and the arc-shaped blades, reaching the inner wall of the host liquid tank. Another portion of the liquid reaches the grid of the rotating component under the negative pressure of the base station motor. Under the collision and centrifugal force of the grid of the rotating component, it is thrown towards the inner wall of the host liquid tank and flows to the bottom of the host liquid tank.

[0161] Optionally, the water tank pipeline cleaning process and the base station drainage cleaning process are continuously cyclically executed multiple times. During the cyclic execution of the water tank pipeline cleaning process, the cleaning component motor rotates in the opposite direction at least once to drive at least a portion of the liquid sucked into the host liquid tank to clean the inner wall of the host liquid tank along different inclines.

[0162] Optionally, during the base station sewage cleaning process, while the base station motor remains running, the base station drain valve (e.g., the aforementioned drain baffle) is opened, and liquid is sprayed through a sprayer and nozzle (the spraying method is similar to that in the aforementioned embodiments) to clean the inner wall of the base station liquid tank through the sprayer and the liquid tank cover through the nozzle, and the liquid in the base station liquid tank is discharged through the base station drain pipe.

[0163] Optionally, after performing the base station drainage cleaning process, if the number of times the self-cleaning operation of the cleaning component has been performed is less than n, the process jumps to performing the self-cleaning process of the cleaning component.

[0164] For example, a base station can provide functions such as water replenishment, sewage discharge, cleaning, storage, drying, and sterilization for floor cleaning. The base station primarily achieves these functions through self-cleaning operation logic. Figure 23 As shown, the user can place the device on the base station and activate the self-cleaning button. The device will first clean the roller brush. After the roller brush is cleaned, the drain valve at the bottom of the wastewater tank will open to discharge the wastewater sucked into the tank. Then, the base station will start filling the cleaning tank with water. Once a certain amount of water is filled, the roller brush will rotate, and the base station motor will start to draw the water from the cleaning tank into the wastewater tank. This process is achieved by the base station motor providing negative pressure through the wastewater drain port (the drain valve of the wastewater tank remains open after self-cleaning begins and is only closed after self-cleaning is completed), drawing the water from the cleaning tank into the wastewater tank and completing the rinsing of the wastewater tank.

[0165] Here, after the liquid flows in from the suction pipe of the machine body, it first passes through the bottom of the high-speed rotating impeller. The bottom of the impeller and the arc-shaped blades on it rotate and throw the liquid to the side onto the inner wall of the machine body's sewage tank. Under the action of negative pressure, some of the water reaches the impeller screen. When the rotating impeller screen collides with the water flow, it is thrown against the inner wall of the sewage tank by the collision and centrifugal force, and flows to the bottom of the sewage tank, thus cleaning the inner wall of the sewage tank.

[0166] During the self-cleaning process of the fuselage wastewater tank, water is continuously supplied and continuously sucked up. After the fuselage wastewater tank completes self-cleaning, the two motors of the main unit and the base station start simultaneously to suck up the water in the cleaning tank. During the self-cleaning process of the fuselage wastewater tank, the separation motor rotates in both directions (due to the impeller's placement, when the impeller rotates in one direction, the dispersed water may only hit one side of the fuselage wastewater tank. Therefore, the impeller can be controlled to rotate in reverse so that the dispersed water hits the other side of the fuselage wastewater tank). This can solve the problem of incomplete cleaning of the fuselage wastewater tank and the existence of cleaning dead corners.

[0167] During the cleaning process, a single motor (i.e., the base station motor) is used to draw water. In this way, when the water level in the cleaning tank is not reached, the suction is insufficient and water cannot be drawn. When the preset water level is reached, that is, when the liquid seals the suction hole, the suction increases and a wave of liquid is drawn away. This intermittent water storage and intermittent water absorption result in a better cleaning effect.

[0168] Here, the separator motor starts before or simultaneously with the main motor of the machine body, which can solve the problem of water vapor entering the main motor of the machine body due to the failure of the water vapor separator motor, thus affecting the service life of the main motor of the machine body.

[0169] The above-described self-cleaning process for wastewater tanks can solve the problems of poor self-cleaning effect, dirt residue, and poor user experience, thereby improving the self-cleaning effect of wastewater tanks and enhancing the user experience.

[0170] For example, such as Figure 24 As shown, the self-cleaning process of the floor scrubber can include a roller brush self-cleaning process, a sewage discharge process, a water tank and pipeline cleaning process, a base station sewage tank sewage discharge and cleaning process, a roller brush self-cleaning replenishment process, a valve closing process, and a drying process. Among these, if the machine body is detected on the base station before starting self-cleaning, a water replenishment process can be executed. Each process is explained below.

[0171] For the water replenishment process, if it is detected that the device is on the base station and the water tank of the device is not full, the water replenishment process of the water tank of the device will be started (the water pump of the base station will run to pump the water in the base station into the water tank of the device).

[0172] For the self-cleaning process of the roller brush, if self-cleaning is started (the water replenishment process will not be interrupted if it is not completed), water will be discharged from the water outlet of the base station base. In conjunction with the rotation of the roller brush, the roller brush will perform self-cleaning. After the roller brush self-cleaning is completed, the main motor of the machine body will start and suck the stored water into the wastewater tank of the machine body. The roller brush self-cleaning will be performed n times in a cycle (before each roller brush self-cleaning, the wastewater tank of the machine body will be checked to see if it is full. If it is not full, the roller brush self-cleaning will be entered. If it is full, the process will switch to the sewage discharge process and the number of roller brush self-cleanings completed will be recorded).

[0173] For the sewage discharge process, start the base station main motor and start the valve opening motor on the machine body (e.g., Figure 25As shown, rotate the valve (the valve opening motor can control the bottom valve to turn left to close the valve, and turn right to close the valve), drive the bottom valve of the sewage tank of the machine body to open, and then the main motor of the base station will continue to run for a period of time before stopping (to ensure that the sewage tank of the machine body is completely emptied), and then start the sewage tank sewage cleaning process of the base station.

[0174] For the base station wastewater tank cleaning process, the base station main motor remains running. A switching motor rotates, and the valves switch, bringing the motor assembly to a positive pressure state. Simultaneously, the valves open the bottom drain port of the base station wastewater tank. Because the motor assembly blows air into the tank, and this bottom drain port is the only outlet, solid particles in the wastewater connection area are quickly expelled, preventing jamming when closing the valve. At the same time, the water distributor and the base station wastewater tank cover spray water to clean the tank walls and cover. After completion, the base station main motor stops, the switching motor reverses its operation, the valves reset, and the bottom valve of the base station wastewater tank closes.

[0175] For the water tank and pipeline cleaning process, water begins to flow from the base station base outlet, the roller brush rotates, the base station main motor starts, and simultaneously, the separator impeller inside the wastewater tank operates in a cutting motion. Under the negative pressure drive of the base station main motor, clean water from the base station base outlet flows through the cleaned roller brush, suction pipe, wastewater tank, base station suction pipe, and base station wastewater tank, cleaning the entire wastewater discharge pipeline. (When the clean water passes through the wastewater tank, due to the water inlet structure design and the rotation of the separator impeller, the clean water is dispersed and evenly rinses the entire inner wall of the wastewater tank, achieving cleaning.) After this process continues for a period of time, it is stopped and the base station wastewater tank cleaning process is restarted, and this cycle is repeated several times. During subsequent cycles, the separator impeller can be controlled to reverse, thereby controlling the clean water to clean along different angles, allowing for more comprehensive cleaning of the inner wall of the wastewater tank.

[0176] For the supplementary roller brush self-cleaning process, if the number of self-cleaning cycles m < n has been completed in the roller brush self-cleaning process, then the roller brush self-cleaning will be run nm more times. During the roller brush self-cleaning at this position, the base station main motor will also be started, and after the roller brush self-cleaning is completed, the base station sewage tank discharge and cleaning process needs to be started.

[0177] For the valve closing process, the main motor of the machine body and the main motor of the base station need to run continuously for a period of time before the self-cleaning process ends to ensure that the roller brush and the corresponding water storage tank are kept as dry as possible. Start the valve opening motor of the machine body to rotate in reverse, driving the valve at the bottom of the wastewater tank of the machine body to close (the valve normally only closes after all self-cleaning is completed to avoid residual dirt at the valve port causing the valve to get stuck).

[0178] For the drying process, start the drying fan and heating source, and at the same time, the roller brush rotates. After running continuously for a period of time (or after checking the dryness of the roller brush), stop the drying fan, heating source and roller brush.

[0179] Here, a disposable filter screen can be installed after the inlet flap of the base station wastewater tank. The presence of the disposable filter screen can be detected using a Hall effect sensor. An open detection Hall effect sensor can be installed on the lid of the base station wastewater tank. Figure 26 As shown. Before the self-cleaning process begins, a Hall effect sensor detects whether the base station's wastewater tank lid is closed. The self-cleaning process starts when the lid is closed. After the self-cleaning process ends, a Hall effect sensor detects that a disposable filter has been installed but not removed after self-cleaning. In this case, the ozone module function is activated. For example, after the drying roller brush has been continuously drying for a period of time, the ozone generator inside the base station can be selectively activated to blow ozone air out of the drying roller brush for sterilization. Simultaneously, after the self-cleaning process is complete, the user can remove and discard the filter and install a new one.

[0180] In this embodiment, after a specified amount of liquid is added to the cleaning tank through the liquid outlet on the base station base, the cleaning component is rotated by the cleaning component motor to perform self-cleaning. This can ensure improved self-cleaning efficiency and avoid interruption of the self-cleaning process due to insufficient liquid for cleaning the cleaning component (for cleaning the cleaning component using the liquid in the clean water tank of the machine body).

[0181] In one exemplary embodiment, the base station further includes a tank cover for the base station liquid tank, the design of which is similar to that in the aforementioned embodiments. For non-automatic closing structures, a tank cover presence detection component can be provided for presence detection of the tank cover. This component can be a tank cover detection Hall sensor; for example, the machine can be equipped with a sewage tank cover detection Hall sensor, which can be used to detect the presence of the base station sewage tank cover.

[0182] For example, the overall structure of the base station sewage tank can be as follows: Figure 27 As shown, when the base station is performing sewage discharge, the sewage tank cover is in a closed state. Combined with the aforementioned negative pressure state (i.e., sewage suction state) and positive pressure state (i.e., sewage discharge state) of the base station's liquid tank, the suction and discharge of the base station's sewage tank are realized.

[0183] Correspondingly, in response to the self-cleaning start signal, the cleaning equipment is controlled to enter the self-cleaning mode, including:

[0184] S91, in response to the self-cleaning start signal, performs on-site detection of the tank cover through the tank cover on-site detection component and obtains the tank cover detection result;

[0185] S92, when the tank cover detection result is used to indicate that the tank cover is in place, the cleaning equipment is controlled to enter the self-cleaning mode.

[0186] For base station liquid tanks with non-automatic closing lids, if the lid is not closed, a negative pressure environment cannot be created during self-cleaning due to the presence of an air intake point (the area covered by the lid), preventing self-cleaning from proceeding. To address this, in response to the self-cleaning start signal, a lid presence detection component detects the lid's presence and obtains the detection result.

[0187] If the tank cover detection result indicates that the tank cover is in place, the cleaning equipment enters the self-cleaning mode and performs the self-cleaning process described above. Otherwise, if the tank cover detection result indicates that the tank cover is not in place, the self-cleaning mode is not entered until the tank cover is detected to be in place. In addition, the cleaning equipment can also be controlled to issue a prompt message to remind the user to close the tank cover of the base station liquid tank.

[0188] For example, the base station's wastewater tank cover is equipped with a Hall effect sensor for presence detection. The self-cleaning program will only start when the wastewater tank cover is in place. If the wastewater tank cover is opened during the self-cleaning process, the self-cleaning program will stop and the user will be reminded to reset it.

[0189] In this embodiment, the success rate of self-cleaning operation can be improved by detecting whether the liquid tank cover of the base station liquid tank is in place by the in-place detection component before entering the self-cleaning mode, and entering the self-cleaning mode when the liquid tank cover of the base station liquid tank is in place.

[0190] In one exemplary embodiment, after detecting the presence of the tank lid using the lid presence detection component, the method further includes:

[0191] S101, when the tank cover detection result is used to indicate that the tank cover is in place, if the duration for which the tank cover has not been opened reaches a second preset duration, a second prompt message is issued through the cleaning equipment, wherein the second prompt message is used to prompt the user to check the dirt status inside the base station tank.

[0192] To prevent excessive dirt buildup in the base station liquid tank due to prolonged lack of cleaning, which could shorten its lifespan, if the tank lid detection result is used to indicate that the tank lid is in place (i.e., the lid is detected to be closed), the duration for which the lid remains closed can be monitored. This monitoring can be continuous, occur during each self-cleaning cycle, or at other times. The duration can be the time difference between the first detection of the lid being in place and the current detection. If the lid is detected to be out of place during this period, the duration is counted again. This embodiment does not limit the timing of the lid being in place or the method of calculating the duration.

[0193] If the duration for which the liquid tank lid remains closed reaches a second preset duration (e.g., 1 day, 1 week, 1 half month, etc., which can be flexibly configured as needed), the cleaning equipment can issue a second prompt message to remind users to check the dirt status inside the base station liquid tank. The prompt may be made in at least one of the following ways: voice prompt, text prompt (displayed on the screen), or visual prompt (displayed on the screen).

[0194] For example, when the program detects that the user has not opened the lid for a long time (which can be detected by the Hall effect sensor on the sewage tank lid), it can remind the user to check the dirt inside the base station's sewage tank through voice or other means.

[0195] This embodiment provides a reminder to check the inside of the base station's liquid tank when the tank lid has not been opened for an extended period. This can improve the lifespan of the base station's liquid tank and enhance the user experience.

It should also be noted that the above modules, as part of a device, can operate in environments such as... Figure 1 The hardware environment shown can be implemented through software or hardware, and the hardware environment includes the network environment.

[0218] According to another aspect of the embodiments of this application, a cleaning device for implementing the control method of the above-described cleaning device is also provided. The cleaning device includes a main unit, a base station, and a control component. The main unit includes a main unit liquid tank, and the base station includes a base station liquid tank, a drive assembly, a first switching valve, and a second switching valve.

[0219] A control unit is configured to, in response to a liquid suction command, control a first switching valve and a second switching valve to be in a first preset state, and control the drive assembly to operate, so that the base station liquid tank is in a negative pressure state, wherein the first switching valve and the second switching valve being in the first preset state is used to instruct the drive assembly to evacuate the base station liquid tank; and in response to a liquid discharge command, control the first switching valve and the second switching valve to be in a second preset state, and control the drive assembly to operate, so that the base station liquid tank is in a positive pressure state, wherein the first switching valve and the second switching valve being in the second preset state is used to instruct the drive assembly to pressurize the base station liquid tank.
