It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In response to the technical problem of inconvenient cleaning of the sewage bucket faced by the existing cleaning device, in some embodiments of the present application, there is provided a cleaning device system, as shown in fig. 1a, including: cleaning device 10 and base station 20. Wherein the cleaning device 10 and the base station 20 can communicate with each other and perform information interaction. The communication manner between the cleaning device 10 and the base station 20 is not limited, for example, an infrared transceiver may be disposed on the cleaning device 10 and the base station 20, and communication is performed between the two via infrared signals; for another example, bluetooth modules are provided on both the cleaning apparatus 10 and the base station 20, and communication between the two may be performed through bluetooth signals; for another example, the cleaning device 10 and the base station 20 are both additionally provided with a WiFi module, and the two modules communicate through WiFi signals; for another example, the cleaning device 10 and the base station 20 may each be additionally provided with a mobile communication module, and the two may communicate with each other through a mobile communication network. Of course, the cleaning device 10 may also be communicatively connected to the base station 20 by wire. In this embodiment, the cleaning device is a hand-held suction cleaner, and in other embodiments, the cleaning device may be a cleaning device for cleaning various surfaces to be cleaned, such as a floor sweeping robot, a carpet cleaner, a cloth cleaner, etc.

In this embodiment, the base station 20 may provide some basic services for the cleaning device 10, for example, the base station 20 may provide docking services for the cleaning device 10, and the cleaning device 10 may dock with the base station 20 when it is not necessary to perform a floor cleaning task; for another example, the base station 20 may also provide charging service for the cleaning device 10, and charging and energy storage may be performed simultaneously when the cleaning device 10 is parked at the base station 20, and of course, charging and energy storage may also be performed by returning to the base station 20 when the electric quantity of the cleaning device 10 is insufficient.

In addition to the basic service described above, in the embodiment of the present application, the functions of the base station 20 are further extended, and the base station 20 may cooperate with the cleaning device 10 to provide a complete cleaning service for the cleaning device 10. In order to achieve the purpose of providing the cleaning device 10 with the cleaning service of the whole machine, a plurality of hardware components, such as a water storage tank, a sewage draining tank, various pipelines communicated with the water storage tank, the sewage draining tank and the like, are additionally arranged on the base station 20; at the same time, the control logic of the base station 20 is improved, and the control logic related to providing the cleaning equipment 10 with the complete machine cleaning service is added to the base station 20, and is implemented in a software program mode. The base station 20 can provide the cleaning device 10 with the overall cleaning service by running the software programs and cooperating with hardware components added to provide the overall cleaning service for the cleaning device 10. The sewage draining groove refers to parts on the base station which are needed for assisting in draining sewage from the sewage bucket on the cleaning equipment, and the structure of the sewage draining groove is not limited, for example, the sewage draining groove can be a sewage draining structure containing a cavity or a sewage draining pipeline without the cavity. For the blowdown structure containing the cavity, the cavity has a certain volume, can accommodate a certain sewage amount, is convenient for carry out sewage discharge with a larger capacity, and can be flexibly arranged according to product requirements. In addition, as can be appreciated by those skilled in the art, the drain tank can flexibly select a drain structure including the cavity or a drain pipe not including the cavity according to application requirements or different scenes.

In the embodiment of the application, the base station 20 provides the cleaning device 10 with the complete machine cleaning service, which is to automatically perform the cleaning process on the cleaning device 10, and the cleaning operation of the cleaning device can be simplified without user intervention in the process, thereby improving the cleaning efficiency. The overall cleaning service provided for the cleaning device 10 mainly comprises two parts, namely self-cleaning of cleaning components on the cleaning device 10 and self-cleaning of a sewage tank on the cleaning device 10. The self-cleaning of the cleaning component mainly comprises the cleaning process of cleaning and drying the cleaning component, so that the self-cleaning task of the cleaning component of the cleaning device 10 is completed; the self-cleaning of the sewage bucket mainly refers to a cleaning process of discharging and cleaning the sewage bucket, namely, discharging sewage in the sewage bucket and flushing the sewage bucket clean, so that the self-cleaning task of the sewage bucket on the cleaning device 10 is automatically completed. Further, in the process that the base station 20 provides the cleaning apparatus 10 with the complete machine cleaning service, cleaning can be performed with respect to the suction passage between the sewage bucket and the cleaning assembly.

Based on the complete machine cleaning service that the base station 20 provided for the cleaning equipment 10, after the cleaning equipment 10 carries out the floor cleaning task and finishes, the user only needs to place the cleaning equipment 10 on the base station 20, and the base station 20 and the cleaning equipment 10 mutually cooperate and can accomplish the self-cleaning of cleaning assembly and the self-cleaning of sewage bucket automatically, after carrying out the self-cleaning action of cleaning assembly, can reach the cleaning purpose of cleaning assembly, after carrying out the self-cleaning action of sewage bucket, can reach the cleaning purpose of sewage bucket to the self-cleaning action of cleaning assembly and sewage bucket that this embodiment provided can also reach better cleaning effect. The user does not need to disassemble the sewage bucket for manual cleaning, the purpose of cleaning the sewage bucket can be achieved, and even self-cleaning of the whole cleaning equipment can be realized, so that the use experience of the user is greatly improved.

It should be noted that, in the whole machine cleaning service, the self-cleaning of the cleaning assembly and the self-cleaning of the sewage bucket may be related to each other or may be independent from each other. For example, the base station 20 may provide self-cleaning services of the sewer piping for the cleaning device 10 alone, or may provide self-cleaning services of the cleaning assembly for the cleaning device 10 alone. Of course, considering that the self-cleaning of the cleaning assembly depends on the sewage bucket, the sewage bucket is required to store sewage generated by the cleaning assembly in the self-cleaning process, so in a preferred embodiment, the two self-cleaning processes can be fused together to be completed in the same process, thereby realizing self-cleaning of the whole machine.

Further, the base station 20 can provide water injection service for the clean water bucket on the cleaning device 10 in addition to the overall cleaning service for the cleaning device 10. Therefore, when the clean water barrel needs to be supplemented with clean liquid, a user can automatically supplement the clean water barrel with the clean liquid without detaching the clean water barrel from the machine body. Here, the clean liquid in the clean water tank may be clean water or various cleaning liquids to which a cleaning agent is added, and is not limited thereto.

Further, the base station 20 can provide the cleaning service for the cleaning device 10 alone, and can also provide the water injection service for the clean water bucket of the cleaning device 10 alone; the cleaning device 10 may be provided with the complete machine cleaning service and the water filling service simultaneously in the same process, for example, the water filling service may be provided for the clean water tank of the cleaning device 10 together in the process of providing the complete machine cleaning service for the cleaning device 10.

It should be noted that, in the process that the base station 20 provides the cleaning device 10 with the complete cleaning service and/or the water filling service, the cleaning device 10 needs to communicate with the base station 20 to synchronize related information or status. The process of performing the self-cleaning of the whole machine by the cooperation of the cleaning device 10 and the base station 20 can be referred to in the following embodiments, and before describing the self-cleaning process of the whole machine, the structures of the cleaning device 10 and the base station 20 according to the embodiments of the present application will be briefly described with reference to fig. 1a and fig. 2.

In the embodiments shown in fig. 3a and 3b, the base station may also control the water storage tank to fill the water tub synchronously in all steps. If the cleaning device provides cleaning fluid from the clean water bucket of the cleaning device during self-cleaning of the floor brush in step 32, the base station controls the water storage tank to synchronously fill water into the clean water bucket in other steps than step 32. This patent is exemplified in step 32 by the fresh water bucket of the cleaning apparatus.

Further, the self-cleaning process of the sewage bucket is split into: three operations of sewage bucket water injection and sewage bucket emptying and sewage bucket flushing, wherein the sewage bucket water injection refers to a process of injecting water into the sewage bucket to enable the sewage bucket to be in a water full state; emptying the sewage bucket refers to a process of opening a sewage outlet of the sewage bucket to discharge sewage to a base station; the bilge tank flushing refers to a process of flushing the inside of the bilge tank until the flushing is finished after the bilge tank is emptied.

It should be noted that in the embodiments shown in fig. 3a and 3b, the first self-cleaning of the wastewater tank includes at least a step of emptying the wastewater tank, and the two steps of filling the wastewater tank and flushing the wastewater tank are optional steps; accordingly, the secondary cleaning of the sewage bucket at least comprises: the steps of emptying the bilge tank and flushing the bilge tank are optional steps for filling the bilge tank with water. Based on this, the process of performing the overall self-cleaning of the cleaning apparatus 10 according to the unified overall cleaning flow shown in fig. 3a and 3b includes the following embodiments:

in specific embodiment A1, as shown in fig. 4a, the whole self-cleaning process of the cleaning device includes the following steps:

(1) The sewage bucket is filled with water, optionally, the clear water bucket is filled with water synchronously;

(2) The sewage bucket is emptied, and optionally, the clear water bucket is synchronously filled with water;

(3) Flushing the sewage bucket, and optionally synchronously injecting water into the clean water bucket;

(4) The cleaning equipment automatically cleans the ground brush;

(5) The sewage bucket is filled with water, optionally, the clear water bucket is filled with water synchronously;

(6) The sewage bucket is emptied, and optionally, the clear water bucket is synchronously filled with water;

further, the whole machine cleaning process of the embodiment shown in fig. 3b further includes the following steps after step (7):

(8) Flushing the sewage draining tank, and optionally, synchronously injecting water into the clean water barrel;

(9) And (5) starting drying and/or sterilizing.

In the step (1), if the water in the clean water barrel is full, the water injection is stopped in the steps (2) and (3), and if the water in the clean water barrel in the step (1) is not full, the water is continuously injected into the clean water barrel in the following steps. And (5) the same as the step (5). In the step (9), drying and/or degerming means drying and/or degerming the floor brush, and the degerming can be performed by adopting a UV lamp.

In specific embodiment A2, as shown in fig. 4b, the whole self-cleaning process of the cleaning device includes the following steps:

(4) The cleaning equipment automatically cleans the ground brush;

(9) And (5) starting drying and/or sterilizing.

In specific embodiment A3, as shown in fig. 4c, the whole self-cleaning process of the cleaning device includes the following steps:

(4) The cleaning equipment automatically cleans the ground brush;

(9) And (5) starting drying and/or sterilizing.

In specific embodiment A4, as shown in fig. 4d, the whole self-cleaning process of the cleaning device includes the following steps:

(4) The cleaning equipment automatically cleans the ground brush;

(9) And (5) starting drying and/or sterilizing.

In the above embodiments A1 to A4, the step (1) is a step that needs to be performed when the wastewater tank is not in a water-full state, and if the wastewater tank is in a water-full state, the step (2) may be directly performed in each embodiment.

In each of the embodiments A1-A4 corresponding to the embodiment shown in fig. 3a, the step (4) may be taken as a division point, the step before the step (4) is a first self-cleaning process for the sewage tank, the step after the step (4) is a second self-cleaning process for the sewage tank, and the step (4) is a self-cleaning process for the floor brush itself. In the above embodiments A1-A4, there is a certain difference in the first self-cleaning process of the wastewater tank, namely, the wastewater tank emptying is an essential step, and the wastewater tank water injection and wastewater tank flushing are optional steps; accordingly, there is a distinction between the secondary self-cleaning process of the wastewater tank, i.e. the wastewater tank emptying and the wastewater tank flushing are essential steps, whereas the wastewater tank filling is an optional step.

The overall flow of the above embodiments A1 to A4 and detailed implementation procedures of the respective steps therein are described below.

Specifically, the user uses the cleaning device to perform a floor cleaning task, and during the floor cleaning task, if any of the following occurs, the user may interrupt the floor cleaning task and place the cleaning device on the base of the base station and complete docking with the base station.

Case 1: in the process of executing the floor cleaning task, the alarm information of insufficient electric quantity sent by the cleaning equipment is received, wherein the alarm information of insufficient electric quantity can be graphic information (such as battery map for highlighting) displayed through a display screen, can be a lamplight signal (such as continuously flashing red light signal) output through a display lamp, and can also be a voice signal output in a voice mode, such as 'insufficient electric quantity of a battery, please charge'.

Case 2: in the process of executing the floor cleaning task, when the sewage tank water full warning information on the cleaning equipment is received, the sewage tank water full warning information can be graphic information (such as a sewage tank map is highlighted or text information of 'sewage tank water full') displayed through a display screen, can be a light signal (such as a continuously flashing green light signal) output through a display lamp, and can also be a voice signal output in a voice mode, such as 'sewage tank water full, please clean'.

Case 3: in the process of executing the floor cleaning task, when the warning information of the insufficient water quantity of the clean water bucket on the cleaning equipment is received, the warning information of the insufficient water quantity of the clean water bucket can be graphic information (such as the graphic information of the clean water bucket, for example, the graphic information of the clean water bucket, or the text information of the too low water level of the clean water bucket) displayed through a display screen, can be a lamplight signal (such as a continuously flashing blue light signal) output through a display lamp, and can also be a voice signal output in a voice mode, such as the voice signal of the insufficient water quantity of the clean water bucket, requesting to add water.

When different alarm information is output through the display lamp, the color of the light signal is different, the light signal with the same color can also be used, but the flashing frequency of the light signal is different, and only the light signal expression mode capable of distinguishing different alarm information is suitable for the embodiment of the application.

In addition to the above, during the performance of the floor cleaning task, if other problems occur, it may also cause interruption of the floor cleaning task, requiring the cleaning device to be placed on the base of the base station and docked with the base station. In addition, after the floor cleaning task is completed, the user may also place the cleaning device on the base of the base station and complete the docking with the base station.

The base station and the cleaning device can detect whether the docking with the opposite end is completed or not. The detection manner of completing the docking is not limited in the embodiment of the present application. When the base station and the cleaning equipment are in butt joint, the cleaning component of the cleaning equipment is positioned in the accommodating groove on the base station base, the sewage outlet of the sewage bucket is in butt joint with the inlet part of the sewage groove, and the water filling port of the clean water bucket is in butt joint with the water filling valve of the water storage bucket; of course, the docking may be accomplished if there are other components to be docked.

Under the condition that the butt joint of the cleaning equipment and the base station is determined, the whole cleaning process of any one of the cleaning equipment in the specific embodiments A1-A4 can be entered, and the whole cleaning process of the finally used cleaning equipment is preset when the product leaves the factory or can be preset by a user.

In embodiments A1-A4, the base station first obtains the water level status of the wastewater tank upon determining that the cleaning device is docked therewith; if the sewage bucket is in a water full state, starting to execute the step (2) in each specific real-time mode; if the wastewater tank is not in a full state, the method starts from the step (1) in each specific embodiment. Here, the water full state may be flexibly defined according to application requirements, for example, a certain ratio (for example, 90%, 4/5) of the entire sewage tank capacity may be defined as a water full state, and a ratio lower than the certain ratio is a water not full state, and a ratio equal to the certain ratio or higher than the certain ratio is defined as a water full state; of course, the ratio may be 100%, i.e. 100% of the capacity of the wastewater tank is defined as a water full state, and all capacity states below 100% are in a water not full state; the range of 80-90% of the capacity of the wastewater tank may also be defined as a water full state, and for the case of more than 90% capacity, an overfill or overflow state, a capacity state of less than 80% as a water not full state.

In the above-described alternative embodiment, a set of electrode pads for detecting whether the sewage tank is in a water-full state is provided in the sewage tank 17 of the cleaning apparatus 10, the ends of the set of electrode pads representing the water-full state; when the sewage in the sewage tank 17 passes the end of the set of electrode pads, the set of electrode pads generates an electrical signal indicating a water full state due to conduction, the set of electrode pads is electrically connected with the processing system of the cleaning device 10, the electrical signal is sent to the processing system of the cleaning device 10, and the processing system can identify whether the sewage tank 17 is in the water full state according to whether the electrical signal indicating the water full state is received or not.

Wherein the cleaning apparatus 10 may detect whether the sewage bucket is in a full state in real time or at a fixed time and transmit indication information of whether the sewage bucket is in a full state to the base station 20, and the base station 20 determines whether the sewage bucket is in a full state according to the indication information of whether the sewage bucket is in a full state transmitted from the cleaning apparatus. Alternatively, the cleaning apparatus 10 detects a water full signal and transmits a state that the wastewater tank is full of water to the base station. Of course, the cleaning apparatus may also transmit the current water level information of the wastewater tank to the base station 20, and the base station 20 may automatically determine whether the wastewater tank is in a full state according to the current water level information of the wastewater tank. If the sewage bucket is in a water full state, directly carrying out sewage disposal treatment on the sewage bucket so as to empty sewage in the sewage bucket; if the sewage bucket is not in the water full state, the water injection treatment is carried out on the sewage bucket, and when the sewage bucket is in the water full state, the sewage discharge treatment is carried out on the sewage bucket so as to empty the sewage in the sewage bucket.

Among these, the water filling treatment of the wastewater tank includes, but is not limited to, the following two methods:

mode 1: the cleaning apparatus is injected into the sewage tank through the fresh water tank. That is, the clean water tank of the cleaning apparatus 10 conveys clean liquid to the cleaning assembly (such as a floor brush or a roll brush) or the accommodating tank through the first water conveying pipeline (the first water conveying pipeline refers to a pipeline between the clean water tank and the nozzles on the cleaning assembly), and then the main motor (also referred to as a suction motor) is started to suck the liquid (i.e. sewage) in the cleaning assembly or the accommodating tank back to the sewage tank through the suction channel until the sewage tank is full of water, so that the purpose of filling the sewage tank with water is achieved. In this embodiment, the receiving tank communicates with the fresh water bucket via a first water supply line and with the sewage bucket via a suction channel.

Alternatively, in mode 1, the cleaning apparatus 10 may actively fill the wastewater tank. Specifically, in case it is determined to dock with the base station, the cleaning apparatus starts to detect whether the sewage bucket is in a water-full state; if the cleaning equipment detects that the sewage bucket is not in the water full state, on the one hand, the indication information that the sewage bucket is not in the water full state can be sent to the base station, so that the base station can know that the sewage bucket is not in the water full state currently, on the other hand, the floor brush motor can be directly controlled to open the water pump to convey clean liquid in the clean water bucket into the cleaning assembly or the accommodating groove, and the main motor is started to suck the liquid in the cleaning assembly or the accommodating groove back into the sewage bucket until an electric signal which is generated by the electrode plate and represents the water full state of the sewage bucket due to the conduction of the water full state is received. When the sewage bucket is filled with water to a water full state, the cleaning equipment can control the clear water bucket to stop conveying liquid and control the main motor to stop sucking. Wherein, when the cleaning device detects the electric signal of the sewage bucket water full, the indication information of the sewage bucket in the water full state is sent to the base station, so that the base station can know that the sewage bucket is in the water full state. Or alternatively

Alternatively, in mode 1, the cleaning apparatus 10 fills the wastewater tank according to the control of the base station 20. In case of determining to dock with the base station, the cleaning device starts to detect whether the sewage tank is in a full state; if the cleaning equipment detects that the sewage bucket is not in the water full state, sending indication information of the sewage bucket not in the water full state to the base station so that the base station can know that the sewage bucket is not in the water full state currently; and the base station returns a water injection instruction to the cleaning equipment according to the indication information that the sewage bucket is not in the water full state, and indicates that the cleaning equipment injects water into the sewage bucket. For the cleaning equipment, according to the water injection instruction returned by the base station, the floor brush motor is controlled to open the water pump to convey clean liquid in the clean water bucket to the cleaning assembly or the accommodating groove, and the main motor is started to suck sewage in the cleaning assembly or the accommodating groove back to the sewage bucket until the cleaning equipment receives an electric signal representing that the sewage bucket is full of water, which is generated by the electrode plate due to full conduction of water. At this time, the cleaning apparatus may control the fresh water tub to stop transporting the liquid and the main motor to stop pumping.

Mode 2: a rinse head is provided in the receiving tank of the base station, the rinse head being in communication with the water storage tank and being capable of spraying liquid towards the receiving tank or the cleaning assembly in the receiving tank, optionally the rinse head being provided on the front wall of the receiving tank, but not limited thereto, for example being capable of being provided around the receiving tank, the number of rinse heads being one or more. Based on this, the base station may fill the wastewater tank through the water storage tank.

Specifically, in case it is determined to dock with the base station, the cleaning apparatus starts to detect whether the sewage bucket is in a water-full state; if the cleaning equipment detects that the sewage bucket is not in the water full state, sending indication information of the sewage bucket not in the water full state to the base station so that the base station can know that the sewage bucket is not in the water full state currently; the base station controls the water storage tank to be filled with water into the accommodating groove through a second water conveying pipeline according to the indication information that the sewage tank is not in a water full state, wherein the second water conveying pipeline comprises a pipeline between the water storage tank and the flushing nozzle, specifically, the water storage tank conveys clean liquid to the flushing nozzle, the flushing nozzle sprays the clean liquid into the cleaning assembly or the accommodating groove, and a suction instruction is sent to the cleaning equipment; according to the suction instruction, the cleaning device starts the main motor to suck the sewage in the cleaning component or the accommodating groove back to the sewage bucket through the suction channel until the sewage bucket is full of water, so that the aim of filling water into the sewage bucket is fulfilled. In the process of filling water into the sewage bucket, the cleaning equipment can continuously detect whether the sewage bucket is in a water full state, and when the sewage bucket is detected to be in the water full state, on one hand, the indication information that the sewage bucket is in the water full state can be sent to the base station, so that the base station can stop filling water into the sewage bucket from the water storage tank according to the notification information, and on the other hand, the main motor can be closed, so that sewage suction is stopped. In this embodiment, the receiving tank communicates with the water storage tank via a second water supply line and with the sewage tank via a suction channel.

In the above-described mode 2, in addition to the main motor being started according to the suction command transmitted from the base station, the cleaning apparatus may automatically start the main motor for sucking the liquid in the accommodating tank or the cleaning assembly into the sewage tank when it is detected that the sewage tank is not in the full state.

In the two embodiments of water injection to the sewage tank, after the clean liquid is delivered to the cleaning assembly or the accommodating groove from the clean water tank on the cleaning device or the water storage tank on the base station, the main motor is started to suck the sewage on the cleaning assembly back to the sewage tank through the suction channel after the clean liquid stays on the cleaning assembly for a certain time, so that the pre-soaking of the floor brush in the cleaning assembly is achieved, and a certain condition is provided for self-cleaning of the follow-up floor brush. In the above process, the residence time of the clean liquid on the cleaning member is not limited, and may be, for example, 2s, 5s, or 5-10s, etc. Of course, the sewage on the cleaning assembly can be sucked back into the sewage bucket in time while the cleaning assembly or the accommodating groove is sprayed with the liquid.

In both embodiments of filling the wastewater tank with water, whether clean liquid is released from the clean water tank of the cleaning device or from the water storage tank of the base station, as indicated by the flow direction of the liquid shown by the gray arrows in fig. 4e, the finally generated wastewater enters the wastewater tank through the floor brush and the suction channel (such as a hose connecting the wastewater tank and the floor brush), and the floor brush and the suction channel are cleaned at the same time, so that the consumption of clean liquid is saved; in addition, after the sewage bucket is filled with liquid, some stains remained on the side wall of the sewage bucket can be taken away, so that more dirt can be taken away, and the cleaning effect is enhanced.

In the above embodiments A1 to A4, after the step (1) is performed, the process proceeds to the step (2). Wherein, in the first self-cleaning process of the sewage bucket, the process of emptying the sewage bucket comprises the following steps: the base station controls the motion mechanism of the base station for opening and closing the sewage bucket to start moving towards the sewage outlet of the sewage bucket until the base station is abutted with the sewage outlet and pushes up the cover plate of the sewage outlet, so that sewage in the sewage bucket flows into the sewage tank through the sewage outlet and the inlet part of the sewage tank to realize sewage discharge. Optionally, the cover plate of the sewage outlet can be fixed through a lock catch, the cover plate is closed in a lock catch closed state, and the cover plate is opened in a lock catch opened state. Based on this, the base station can control the motion of motion towards the drain, and the hasp of closure drain apron is opened in the top, and then opens the apron of drain, and sewage in the sewage bucket flows into the drain groove on the base station through the entry portion of drain and drain groove, and external drain that is finally connected by the drain groove is with sewage drainage sewer or other sewage passageway, realizes the blowdown.

In order to judge whether the sewage bucket emptying process is finished, a threshold value of the sewage bucket time period required for emptying from full water can be preset on the base station, based on the threshold value, the sewage bucket time period is counted at the beginning of the sewage bucket emptying operation, and when the sewage bucket time period reaches the preset sewage time period threshold value, the sewage bucket emptying operation is determined to be finished. At this time, in the specific embodiments A3-A4, the base station may send a notification message to the cleaning device that the sewage tank is empty, so as to instruct the cleaning device to perform self-cleaning on the floor brush or inform the cleaning device to enter the next step; in embodiments A1-A2, the base station may begin performing the bilge tank flushing operation.

In the above embodiments A1 to A2, after the step (2) is performed, the process proceeds to the step (3). Wherein, in the first self-cleaning process of the sewage bucket, one implementation process of the sewage bucket flushing includes: under the condition that the sewage outlet of the sewage bucket is opened, the base station controls the flushing device for flushing the sewage bucket to start moving towards the sewage outlet (for example upwards) until the flushing device stretches into the sewage bucket and reaches a designated position, then the flushing device starts to reciprocate, the sewage bucket is flushed in the reciprocating motion process, and liquid for flushing the sewage bucket flows into the sewage tank through the sewage outlet and the inlet part of the sewage tank and is discharged, so that flushing of the sewage bucket is realized; and when the flushing times reach the set first time number threshold value or the flushing time reaches the set first time length threshold value, ending the flushing action, and restoring the flushing device for flushing the sewage bucket to the original position. For example, the first time threshold may be 3 times, 5 times, or the like, and the first time threshold may be 3s, 7s, 10s, or the like, which is not limited.

Wherein, in the first self-cleaning process of the sewage bucket, another implementation process of the sewage bucket flushing includes: the water storage barrel is also communicated with the water injection port of the sewage barrel, the base station controls the water storage barrel to inject clean liquid into the sewage barrel through the water injection port of the sewage barrel, preferably, the liquid can be injected into a first designated position of the sewage barrel through the water injection port, the first designated position is a relatively higher position of the sewage barrel, such as a barrel cover position, so that the liquid can be in a downward injection state from a high position, the aim of flushing the sewage barrel is fulfilled, and finally, the liquid injected into the sewage barrel flows to the sewage outlet and flows out to the sewage draining groove through the sewage outlet and the inlet part of the sewage draining groove. Alternatively, the water filling opening of the sewage tank may be provided at the bottom bracket of the sewage tank, and for this arrangement, the liquid may be allowed to reach the first designated position in the sewage tank by a larger water pressure or a larger amount of water, but is not limited thereto. Alternatively, in another alternative embodiment, a water filling port may be formed at a higher position of the sewage tank, for example, near a side wall of the tank cover, or near the tank cover, so that the liquid is filled into the sewage tank through the water filling port, and a state of spraying from a higher position to a lower position may be achieved.

In order to judge whether the washing process of the sewage bucket is finished, a first washing frequency threshold value or a first time length threshold value required in the first self-cleaning process of the sewage bucket can be preset on the base station; based on this, the number of times of flushing or flushing time of the wastewater tank is counted at the beginning of the wastewater tank flushing operation, and when the number of times of flushing or flushing time of the wastewater tank reaches a preset first flushing number threshold or first time threshold, it is determined that the wastewater tank flushing operation is ended. Alternatively, in the solution of flushing the wastewater tank based on the flushing device, the base station may also detect whether the flushing device is returned to the original position to determine whether the wastewater tank flushing operation is ended, and determine that the wastewater tank flushing operation is ended when detecting that the flushing device is returned to the original position. In the scheme of performing the flushing operation on the sewage bucket through the flushing device, the flushing times can be determined according to the reciprocating times of the flushing device, for example, the reciprocating times are the flushing times when the reciprocating times are calculated once, or the reciprocating times are the flushing times when the reciprocating times are calculated twice, and the like. Of course, in the solution of performing the flushing operation of the sewage tank by the flushing device, the flushing time period may also be counted, and the end of the flushing operation is determined when the flushing time period reaches the first time period threshold. Accordingly, in the scheme of injecting liquid into the sewage tank through the water storage tank to perform flushing operation on the sewage tank, the time period of injecting the liquid into the sewage tank from the water storage tank (simply referred to as water injection time period) can be counted, and when the water injection time period reaches a set first water injection time period threshold value, the end of the flushing operation of the sewage tank is determined. At this time, in embodiments A1-A2, the base station may send a notification message to the cleaning device that the bilge tank flushing is complete to instruct the cleaning device to self-clean the floor brush.

After the first self-cleaning of the sewage bucket is completed, the method enters the step (4) in the specific embodiments A1-A4 to perform self-cleaning on the ground brush. The cleaning equipment determines that the floor brush needs to be self-cleaned according to a notification message sent by the base station that the sewage bucket is emptied or cleaned, and then the cleaning equipment controls the water cleaning bucket and the main motor to alternately execute water outlet operation and water pumping operation on the cleaning assembly or the accommodating groove so as to realize the self-cleaning of the floor brush.

Specifically, the floor brush self-cleaning includes two stages, namely a first stage and a second stage. In the first stage, the cleaning device controls the water cleaning barrel to output a specified amount of liquid to the accommodating groove in the first water outlet operation, specifically controls the floor brush motor to turn on the water pump, so that clean liquid in the water cleaning barrel is sprayed to the accommodating groove by a specified amount through a first water conveying pipeline (the first water conveying pipeline comprises a pipeline from the water cleaning barrel to a nozzle on the cleaning assembly and the nozzle); and after waiting for the third period of time, controlling the main motor to perform first pumping operation at a fourth period of time, namely sucking the sewage generated by soaking the floor brush back to the sewage bucket through the suction channel, wherein the suction process lasts for the fourth period of time. Wherein the purpose of waiting for the third period of time is to allow the liquid to soak the brush sufficiently, and the first stage is to output a specified amount of liquid from the water tub in order to allow a sufficient amount of liquid to soak the brush.

In an alternative embodiment, the threshold value of the liquid amount released by the clean water bucket for the first time in the self-cleaning process of the floor brush can be preset, a water amount detection sensor is arranged in the accommodating groove of the base, the water amount detection sensor is used for detecting whether the liquid amount released by the clean water bucket reaches the set threshold value of the liquid amount, and when the set threshold value of the liquid amount is reached, the clean water bucket is controlled to stop releasing clean liquid, and the liquid amount is considered to reach the designated amount required by soaking the floor brush. Or in another alternative embodiment, a threshold value of the time period for the clean water bucket to release the liquid for the first time in the self-cleaning process of the floor brush, for example, a third time period threshold value, is preset, and when the time period for the clean water bucket to release the clean liquid reaches the third time period threshold value, the clean water bucket is controlled to stop releasing the clean liquid, so that the liquid amount reaches the designated amount required for soaking the floor brush at the moment.

In the second stage, the water outlet operation and the water pumping operation are alternately performed by controlling the water cleaning barrel and the main motor according to the first time length and the second time length which are respectively corresponding to each other, for example, the water cleaning barrel performs the water outlet operation each time according to the first time length, and then the main motor performs the water pumping operation according to the second time length, wherein the water pumping operation refers to pumping liquid released by the water cleaning barrel into the sewage barrel through the pumping channel.

The water outlet operation and the water pumping operation are alternately executed for a plurality of times until reaching a preset second time threshold, or the water outlet operation and the water pumping operation are alternately executed for a plurality of times until reaching a specified second time threshold, or the water outlet operation and the water pumping operation are alternately executed for a plurality of times until the sewage bucket is in a water full state again, so that self-cleaning of the floor brush is completed. The first duration and the second duration may be the same, for example, both 1s, 3s, etc. Alternatively, the first time period and the second time period are different, preferably the second time period is longer than the first time period, for example, the first time period may be 1s, the second time period may be 2s, the first time period may be 2s, the second time period may be 3s, and so on. Accordingly, the value of the fourth duration is not limited, and may be, for example, 5s, 7s, or the like, alternatively, the fourth duration may be greater than the second duration, but is not limited thereto. The fourth time period is related to the amount of the specified first water outlet, and is longer if the specified first water outlet is larger, and shorter if the specified first water outlet is smaller. Correspondingly, the longer the first time length is, the more water is required to be pumped, so the longer the second time length is, the shorter the first time length is, the less water is required to be pumped, and the shorter the second time length is.

In this embodiment, the value of the third period is not limited to the above, and may be, for example, 3s, 5s, 10s, 20s, etc., and the third period may be a preset value, or may be flexibly set according to the dirt level of the floor brush. A soil degree sensor can be arranged on the floor brush, and the soil degree of the floor brush is collected through the soil degree sensor and reported to a processing system of the cleaning equipment; or, the cleaning equipment can be provided with a camera, the image of the floor brush is collected through the camera, and the cleaning equipment or the service end identifies the image to obtain the dirt degree information of the floor brush. After the soil program information of the floor brush is obtained, the third time period may be set according to the soil degree information of the floor brush, and the third time period may also be referred to as a soaking time period of the floor brush. Besides the image of the ground brush collected by the camera on the cleaning device, the image of the ground brush can also be collected by the camera on the base station or the camera on other terminal devices (such as a mobile phone provided with the cleaning device APP) and uploaded to a server for image recognition, which is not limited.

In the self-cleaning process of the floor brush, the clean liquid released by the clean water barrel is used for soaking the cleaning component for a certain time, so that dirt on the floor brush can be dissolved in advance, and dirt which is difficult to clean can be removed, and the floor brush can be cleaned better; in addition, a certain time is reserved, and more liquid released by the clear water barrel can be accumulated, so that when the main motor works, enough liquid can flush the suction channel (such as a hose) to clean the whole air channel better.

Furthermore, when the self-cleaning end condition of the local brush is that the sewage bucket is in a water full state again, more dirty dirt in the sewage bucket can be further taken away, a certain burden is reduced for the subsequent secondary self-cleaning process of the sewage bucket, the cleaning effect is enhanced, and the water consumption is saved.

In an alternative embodiment, the clean water bucket is provided with the electrolyzed water preparation equipment, the cleaning equipment can control the electrolyzed water preparation equipment to prepare electrolyzed water for a period of time, and then the water pump is turned on by the floor brush motor to enable the electrolyzed water in the clean water bucket to be sprayed out of a specified amount through the nozzle on the cleaning assembly, so that the floor brush can be soaked and cleaned by using the electrolyzed water, and the sterilization effect can be achieved.

In this embodiment, when the self-cleaning end condition of the floor brush is that the number of times of alternately performing the water outlet operation and the water pumping operation reaches the second time threshold, the cleaning device may count the number of times of alternately performing the water outlet operation and the water pumping operation in the self-cleaning process of the floor brush, and determine that the self-cleaning operation of the floor brush is ended when the second time threshold is reached, send a notification message of completion of self-cleaning of the floor brush to the base station to instruct the base station to enter the secondary self-cleaning process of the sewage tank. Or under the condition that the self-cleaning end condition of the floor brush is that the time for alternately executing the water outlet operation and the water pumping operation reaches a second time threshold, in the self-cleaning process of the floor brush, the cleaning equipment can count the time for alternately executing the water outlet operation and the water pumping operation, and when the time for alternately executing the water outlet operation and the water pumping operation reaches the second time threshold, the self-cleaning end of the floor brush is determined, and a notification message for the self-cleaning completion of the floor brush is sent to the base station so as to instruct the base station to enter the secondary self-cleaning process of the sewage bucket. Or in the case that the self-cleaning end condition of the floor brush is that the sewage bucket is in the water full state again, the cleaning equipment can also detect the state of the sewage bucket in the self-cleaning process of the floor brush, and when the sewage bucket is determined to be in the water full state again, determine that the self-cleaning of the floor brush is ended, send a notification message of the self-cleaning completion of the floor brush to the base station so as to instruct the base station to enter the secondary self-cleaning process of the sewage bucket.

After the self-cleaning operation of the floor brush is completed, the secondary self-cleaning process of the sewage bucket is entered in each of the above-described embodiments A1 to A4, but the secondary cleaning process of the sewage bucket is different in the above-described embodiments A1 to A4. Specifically, in embodiments A1 and A3, steps (5) - (7) are sequentially performed, namely, the wastewater tank is filled first, the wastewater tank is emptied after the wastewater tank is filled, and the wastewater tank is flushed after the wastewater tank is emptied; in embodiments A2 and A4, steps (6) and (7) are performed sequentially, i.e. the bilge tank is emptied first, followed by a bilge tank flush.

In the embodiments A1 and A3, since the self-cleaning of the floor brush will not normally be performed in a state of full water, water can be directly injected into the sewage tank, and the foregoing manner 1 and 2 are referred to for the manner of injecting water into the sewage tank, and will not be repeated here.

In embodiments A1-A4, each includes a step (6) of bilge tank emptying and a step (7) of bilge tank flushing. The specific implementation flow and the parameters related to the step (6) are the same as those of the step (2), and are not described herein. The specific implementation flow of the step (7) is the same as that of the step (3), and will not be described here again. Step (7) belongs to the sewage bucket flushing operation in the secondary self-cleaning process, and step (3) belongs to the sewage bucket flushing operation in the primary self-cleaning process, wherein the two flushing parameters can be the same or different.

For example, in the wastewater tank flushing operation of step (7), when the condition for the end of the flushing operation may be set to a third time threshold or a third time period threshold, based on which, during the execution of step (7), in a case where the wastewater outlet of the wastewater tank is opened, the base station controls the flushing device on the base station to start moving upward until reaching into the wastewater tank and reaching a designated position, and then starts to reciprocate, flushing the wastewater tank during the reciprocation; and when the flushing times reach a set third time threshold or the flushing time reaches a set third duration threshold, ending the flushing action, and restoring the flushing device for flushing the sewage bucket to the original position. For example, the third time threshold may be 5 times, 8 times, 10 times, etc., and the third time period threshold may be 5s, 10s, 15s, etc., which is not limited. Of course, in the execution of step (7), the base station may also detect whether the flushing device returns to the original position to determine whether the flushing operation is finished, and determine that the flushing operation is finished when detecting that the flushing device returns to the original position again, otherwise, the re-operation is not finished yet. In the scheme of performing the flushing operation on the sewage bucket through the flushing device, the flushing times can be determined according to the reciprocating times of the flushing device, for example, the reciprocating times are the flushing times when the reciprocating times are calculated once, or the reciprocating times are the flushing times when the reciprocating times are calculated twice, and the like. Of course, in the solution of performing the flushing operation on the sewage tank by the flushing device, the flushing time period may also be counted, and when the flushing time period reaches the third time period threshold value, the end of the flushing operation is determined. Accordingly, in the scheme of injecting liquid into the sewage tank through the water storage tank to perform flushing operation on the sewage tank, the time period of injecting liquid into the sewage tank from the water storage tank (simply referred to as water injection time period) can be counted, and when the water injection time period reaches a set second water injection time period threshold value, the end of the flushing operation of the sewage tank is determined.

Optionally, the number of times of flushing the wastewater tank may be greater or the flushing time may be longer during the second self-cleaning of the wastewater tank, for example, the third time threshold may be greater than the first time threshold, or the third time period threshold may be greater than the first time period threshold, or the second water injection time period threshold may be greater than the first water injection time period threshold, relative to the number of times of flushing or the flushing time in the first self-cleaning, to ensure the cleaning effect of the wastewater tank. However, the third time threshold is not limited to be greater than the first time threshold, or the third time threshold is greater than the first time threshold, or the second water injection time threshold is greater than the first water injection time threshold, and if the number of times of flushing is enough or the flushing time is long enough in the first self-cleaning process, and a certain cleaning effect has been achieved on the sewage tank, then in the second self-cleaning process, fewer times of flushing or flushing time or water injection time can be used, so long as the sewage tank can be ensured to be cleaned in the second self-cleaning process.

Further, in the above embodiments A1 to A4, after the step (7) is performed, the base station controls the movement mechanism of the opening and closing sewage tank to move in a direction away from the sewage outlet of the sewage tank, thereby closing the cover plate of the sewage outlet of the sewage tank, closing the latch of the sewage tank to lock the sewage tank, and then sending a notification message of complete machine cleaning completion to the cleaning device, so that the cleaning device knows that complete machine self-cleaning is completed.

Further, as shown in the embodiment of fig. 3b, after the complete machine of the complete cleaning apparatus is cleaned, step 34 may be entered to perform self-cleaning on the drain tank on the base station. Specifically, as shown in fig. 4f, there is a third water supply line 219 between the water storage tank 211 and the sewage tank 213, and a switch valve lever is provided on the third water supply line 219, optionally, the switch valve lever is provided in the water storage tank for opening or closing the third water supply line 219; after the sewage tank is thoroughly cleaned, the base station controls the valve rod in the water storage tank 211 to be opened, the water storage tank releases clean liquid, the clean liquid directly flows to the sewage tank 213 through the third water supply pipeline 219 connected with the sewage tank, the sewage tank 213 is washed, and the liquid after washing the sewage tank flows into a sewer through the sewer connecting pipe connected with the sewage tank 213, so that self-cleaning of the sewage tank is realized. In fig. 4f, the grey arrow lines indicate the flow of liquid when the drain tank is flushed.

In the above embodiments A1-A4, after flushing the drain tank, the cleaning assembly may also be sterilized by turning on a UV lamp provided on the base station. Optionally, the UV lamp is arranged on a base of the base station, and is used for emitting ultraviolet rays with sterilization, and is used for carrying out irradiation sterilization on the cleaning component (particularly the floor brush) so as to prevent bacteria from breeding on the floor brush; in addition, the UV lamp also has the functions of heating and drying the cleaning assembly, and accelerates the drying speed of the floor brush. Furthermore, a set of drying system can be additionally arranged on the base, and the system comprises a heating module arranged in the base, a diversion channel and an exhaust hole arranged in the accommodating groove, wherein the exhaust hole is communicated with the diversion channel; after the drying system is started, the heating module starts to work to generate hot air, the hot air reaches the air outlet through the flow guide channel, the hot air is blown out from the air outlet towards the cleaning assembly, and the cleaning assembly can be dried simultaneously in the process of sterilizing the cleaning assembly by UV and the like.

In the self-cleaning process of the whole machine, the cleaning equipment can also detect the water level state of the clean water barrel through a group of electrode plates in the clean water barrel, wherein the electrode plates are used for detecting whether the clean water barrel is in a water full state, the tail end positions of the electrode plates represent the water full state of the clean water barrel, and in the water full state, the group of electrode plates can generate an electric signal representing the water full state; in a non-water full state, the electric signal is not generated; the cleaning apparatus may determine whether the fresh water tub is in a water full state according to whether the electric signal is received. When the clear water barrel is not in a water full state, the cleaning equipment sends indication information that the clear water barrel is not in the water full state to the base station, and the base station injects water to the clear water barrel through the water storage tank according to the information, specifically, a water injection valve communicated with the water storage tank is opened, so that clean liquid in the water storage tank flows to the clear water barrel through the water injection valve and a water injection port of the clear water barrel, and the aim of injecting water to the clear water barrel is fulfilled. In the process, when the water level information of the water purifying barrel exceeds the tail end position of the electrode slice, the electrode slice generates an electric signal which indicates that the water purifying barrel is in a water full state and sends the electric signal to a processing system of the cleaning equipment; the cleaning device judges whether the water cleaning barrel is in a water full state according to whether the electric signal is received or not. In the water injection process to the clear water barrel, when the cleaning equipment receives the electric signal generated by the electrode plate, the cleaning equipment sends indication information that the clear water barrel is in a water full state to the base station, and the base station closes the water injection valve according to the indication information, so that water injection to the clear water barrel is stopped.

In the above embodiment, when the clean water bucket is not in the water full state, the base station is required to fill the clean water bucket, so that the clean water bucket is always kept in the water full state, but the present invention is not limited thereto. For example, two groups of electrode plates can be arranged in the clean water barrel, the tail end position of the first group of electrode plates is lower than the tail end position of the second group of electrode plates, namely, the tail end position of the first group of electrode plates is closer to the bottom position of the clean water barrel, the tail end position of the second group of electrode plates is closer to the top position of the shoulder clean water barrel, the first group of electrode plates are used for detecting the lowest water level of the clean water barrel, and the second group of electrode plates are used for detecting the water full state of the clean water barrel. When the water level in the clean water bucket is lower than the tail end position of the first group of electrode plates, the first group of electrode plates are disconnected, an electric signal generated by the first group of electrode plates can be informed, the cleaning equipment can judge that the water level of the clean water bucket is lower than the lowest water level according to the disappearance of the electric signal, and then a water injection request is sent to the base station, so that the base station injects water into the clean water bucket through the water storage tank. Along with continuous water injection, the water level in the clean water barrel gradually rises, when the water level rises to the tail end position of the second group of electrode plates, the second group of electrode plates are conducted to generate an electric signal, at the moment, the cleaning equipment can judge that the water level of the clean water barrel exceeds the highest water level according to the electric signal, namely, the clean water barrel is in a water full state, and then a notification message that the clean water barrel is in the water full state is sent to the base station, so that the base station stops water injection to the clean water barrel.

Further alternatively, a plurality of groups of electrode plates can be further arranged, the tail end positions of different electrode plates are positioned at different positions in the clean water barrel, a plurality of water level detection can be performed on the clean water barrel, and whether water needs to be injected into the clean water barrel is judged according to the detection result of each water level.

In the above embodiments A1 to A4, in the case that the wastewater tank is not in a water full state, the reason why the water injection of step (1) into the wastewater tank is performed is as follows: after the cleaning device performs floor cleaning, the dirt level in the waste water tank may be serious, and some solid waste or waste adhered to the tank wall may be in the waste water tank, so that the waste water tank is filled with water first, which is helpful for flushing the waste on the tank wall from the tank wall or discharging the drier and sticky waste, and therefore, the waste water tank needs to be filled before the waste water tank is emptied to be beneficial for dirt discharge.

The reason for performing steps (1) - (3) prior to step (4) is: before the self-cleaning of the floor brush, the sewage bucket is emptied and primarily cleaned, the dirt recovered from the cleaning ground of the cleaning equipment is discharged and the residual dirt in the sewage bucket is washed away, so that the sewage bucket is in a relatively clean state, the floor brush of the cleaning equipment is then self-cleaned, the dirt degree at the moment is generally lighter than the dirt recovered from the cleaning ground, and the subsequent re-washing of the recycling bin becomes relatively easy because the sewage bucket is pre-cleaned, so that the floor brush is convenient to self-clean. If the sewage bucket is in a water full or full state, the floor brush cannot be self-cleaned or the self-cleaning of the floor brush cannot be completed at one time, so that the cleaning efficiency is low. On the other hand, since the user is not finished cleaning the floor while the sewage tank is full and/or the fresh water tank is empty, the user may only need to empty the sewage tank to fill the fresh water tank instead of brushing the floor self-cleaning, and thus steps (1) - (3) are performed before step (4).

In addition, in the embodiments A1 and A2, the reason for providing the step (3) between the steps (2) to (4) is that: the floor cleaning is performed by the cleaning device, although the sewage bucket is emptied in the step (2), the sewage recovered by the cleaning device for cleaning the floor may be heavy, the sewage bucket may still be dirty, the sewage brought by the floor cleaning is washed away firstly, and the sewage bucket is more easily washed clean when the sewage bucket is washed in the step (7) after the step (4).

It should be noted that, in the embodiments of the present application, in the case that a display screen is provided on the main body of the cleaning apparatus, the display screen may display what stage the cleaning process of the whole machine is currently, and the progress condition of the cleaning process of the whole machine (for example, specifically performed step information), and these stage information and step information may be sent to the cleaning apparatus by the base station, and the cleaning apparatus may display the stage and step information through the display screen, so that the user may know the current cleaning stage and step.

Fig. 5 is a schematic flow chart of a self-cleaning method of a cleaning device described from the perspective of the cleaning device according to an embodiment of the present application. As shown in fig. 5, the method includes:

51. determining whether the sewage bucket is in a water full state in a case that the cleaning device is docked with the base station;

In an alternative embodiment, the method further comprises: detecting whether the water tank is in a water full state or not, and sending indication information of whether the water tank is in the water full state or not to the base station so as to enable the base station to perform water injection treatment on the water tank.

For detailed implementation of the above method steps, reference may be made to the description of the foregoing system embodiments, which are not repeated here.

In addition to the above methods and systems, embodiments of the present application provide a base station and a cleaning device. The structure of the base station may refer to the embodiment shown in fig. 1a, 1b or 2, and the details of the steps that may be executed by the base station in the above embodiments may be realized by executing the computer program stored in the memory by the controller in the base station, and the details of the steps of the methods are also referred to the above embodiments, and are not repeated herein.

Similarly, the structure of the cleaning apparatus may be referred to in the embodiment shown in fig. 1a, 1b or 2, and the processing system in the cleaning apparatus may implement the steps that may be performed by the cleaning apparatus in the above method embodiments, and the detailed description of the method steps is referred to in the foregoing embodiments, which are not repeated herein.

A specific scenario example 1 is given below:

after the user finishes the work such as floor cleaning by using the cleaning machine, the cleaning machine is put back on the base of the base station and is in butt joint with the base station. And under the condition that the base station detects that the butt joint with the cleaning machine is finished, starting a complete machine self-cleaning process of the cleaning machine. The base station controls the water storage barrel to fill the sewage barrel with clean water until the sewage barrel is full of water, and controls the driving mechanism to open the cover plate on the sewage outlet of the sewage barrel for sewage drainage, and sewage flows into the sewer through the sewage drainage groove; after sewage is discharged for 10 seconds, the flushing device for flushing the sewage bucket is driven to rise to a designated position in the sewage bucket, repeated up-and-down movement is started, clear water is sprayed out in the repeated up-and-down movement process (for example, the flushing device can be provided with a rotary spray head for spraying water towards the periphery or a plurality of spray heads for spraying water towards different directions towards the periphery) so as to flush all positions in the sewage bucket; after flushing the wastewater tank 30s, the flushing device returns to the original position (i.e., reset); at this time, the moving mechanism for opening and closing the sewage bucket is driven to move in the reverse direction, so that the cover plate is closed to close the sewage bucket. The washer is then notified that the brush is ready for self-cleaning. The cleaning machine starts to prepare electrolyzed water in the clean water bucket for 30s, the clean water bucket sprays a certain amount of electrolyzed water through a nozzle on the cleaning component, and after soaking the rolling brush for 15s, the main motor is driven to work for 3s so as to suck sewage into the sewage bucket; then, the clear water bucket sprays water for 1s to the accommodating groove through the nozzle, the main motor is driven to work for 1s, after the main motor circulates for several times in sequence, finally, the main motor pumps the sewage in the accommodating groove into the sewage bucket completely, and the floor brush is air-dried, so that self-cleaning of the floor brush and the whole air duct is completed. Then, driving the motion mechanism to move towards the sewage outlet of the sewage bucket again, opening a cover plate on the sewage outlet to carry out sewage, driving a flushing device for flushing the sewage bucket to rise to a designated position in the sewage bucket after sewage is discharged for 10 seconds, starting flushing the sewage bucket, and returning the flushing device to an initial position (namely resetting) after flushing the sewage bucket for 30 seconds; at this time, the moving mechanism for opening and closing the sewage bucket is driven to move in the reverse direction, so that the cover plate is closed to close the sewage bucket. Finally, the water storage tank on the base station is drained to flush the sewage draining tank, and the whole self-cleaning process is completed. In the whole process, the user does not need to clean the cleaning machine, so that the purpose that the hands of the user are not stained is achieved.

Here, the base station automatically starts the whole cleaning process for the cleaning device in the case that the cleaning device is docked with the base station, but is not limited thereto. For example, after the user places the cleaning device on the base station, a voice command to start the overall cleaning process may be sent to the base station and/or the cleaning device via a voice signal. The voice command for starting the whole machine cleaning flow can be sent towards the base station, and then the base station sends a control command to the cleaning equipment so that the cleaning equipment enters the whole machine cleaning flow and completes the whole machine cleaning flow in cooperation with the base station; or, the voice command for starting the whole machine cleaning flow can be sent out by facing the cleaning equipment, and then the cleaning equipment sends a notification message to the base station so that the base station enters the whole machine cleaning flow and completes the whole machine cleaning flow in cooperation with the cleaning equipment; or, the voice command for starting the whole machine cleaning flow can be sent out simultaneously by facing the cleaning equipment and the base station, and the cleaning equipment and the base station enter the whole machine cleaning flow simultaneously. For another example, after the user places the cleaning device on the base station, the user may send an instruction to start the complete machine cleaning process to the cleaning device or the base station through a self-cleaning button on the display screen of the cleaning device or a self-cleaning button on the display screen of the base station, so as to start the complete machine cleaning process. Of course, the user can also send an instruction for starting the whole machine cleaning process to the cleaning equipment or the base station through a physical button on the cleaning equipment or the base station, so that the whole machine cleaning process is started.
