[0059] A wet cleaning device is a device used to clean the ground. When the wet cleaning device is cleaning, it simultaneously sucks up the sewage on the ground and takes the sewage away from the site; the wet cleaning device can specifically be an autonomous cleaning device such as a mopping robot, a floor washing robot, a sweeping and mopping integrated machine, etc., or a semi-automatic cleaning device such as a handheld floor washer, etc. The wet cleaning device is equipped with a charging base station, and the charging base station can be used for charging and self-cleaning of the wet cleaning device. The charging base station includes a tray for supporting the wet cleaning device; the bottom end of the wet cleaning device has a rotary brush for cleaning the ground. After the cleaning work of the wet cleaning device is completed, the wet cleaning device is placed on the tray, and the wet cleaning device can perform self-cleaning on the rotary brush to clean the rotary brush for the next ground cleaning.

[0060] The steps of the current wet cleaning device during self-cleaning are as follows: the wet cleaning device injects water into the rotary brush, and at the same time the rotary brush rotates, and this continues for a period of time to achieve the cleaning effect; however, the above steps only perform simple water injection cleaning on the rotary brush, and generally cold water is used for cleaning, and the cleaning effect is very limited, and it is impossible to judge whether the rotary brush is cleaned; it is easy to have the problem that the rotary brush is not cleaned cleanly, which is likely to breed bacteria and produce odors; in addition, during the self-cleaning process, the rotary brush is likely to generate sewage on the tray, making the tray dirty or wet, and the current wet cleaning device does not consider how to reduce the sewage.

[0061] Based on this, to solve the above problems, the present application designs a self-cleaning method for a cleaning device, which realizes a fully automated self-cleaning process for the mopping member through the cleaning device. The cleaning device can intelligently determine whether it meets the self-cleaning working conditions to enter the self-cleaning mode; and the cleaning device can heat the cleaning liquid to clean the mopping member, and clean the mopping member multiple times in a cycle, which can better clean the mopping member; until the preset exit condition is met, the self-cleaning mode is exited to ensure that the mopping member is cleaned thoroughly. The entire self-cleaning process is highly intelligent, and can achieve efficient and comprehensive cleaning operations for the cleaning device. Its self-cleaning method is simple and efficient. In addition, during the entire process of cleaning the mopping member, the supply of liquid, heating, and recovery of sewage are all realized by the cleaning device itself. The entire self-cleaning process is highly intelligent; the charging base only serves to support the cleaning device, and the cleaning device itself has complete functionality.

[0062] Please refer to Figure 3 、 Figure 4 , the first aspect of the present application provides a cleaning system, including a cleaning device 100 and a charging base 200. The charging base 200 is configured to dock with the cleaning device 100 to perform work such as charging and self-cleaning of the cleaning device 100; the charging base 200 includes a tray 201 for carrying the cleaning device 100, and the cleaning device 100 includes a mopping member 101 for cleaning the ground.

[0063] Specifically, the cleaning device 100 can be placed on the tray 201 of the charging base 200 and perform self-cleaning on the mopping member 101; a cleaning tank 202 is formed on the tray 201 of the charging base 200. The mopping member 101 of the cleaning device 100 can be a roller brush or a mop cloth, etc. The sewage generated during the self-cleaning process of the mopping member 101 can converge in the cleaning tank 202 of the tray 201, and the cleaning tank 202 can store part of the sewage to prevent the sewage from overflowing the tray 201.

[0064] In some embodiments, the mopping member 101 of the cleaning device 100 is a roller brush, which rotates to brush the ground, and the cross-section of the roller brush is disk-shaped; the cross-section of the cleaning tank 202 is arc-shaped, and the arc contour of the cleaning tank 202 is adapted to the roller brush, so that when the cleaning device 100 is placed on the tray 201, the cleaning tank 202 can accommodate at least part of the roller brush to cooperate with the cleaning operation of the roller brush, thereby realizing the self-cleaning of the cleaning device 100.

[0065] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 7, in one embodiment, the cleaning device 100 includes a cleaning module 300 and a control module 400; the cleaning module 300 includes a mopping member 101 for cleaning the floor, a driving component for driving the mopping member 101, a liquid supply component 102 for supplying cleaning liquid to the mopping member 101, and a suction component 103 for providing suction force to suck sewage; the control module 400 is electrically connected to the cleaning module 300; the control module 400 includes a processor 401 and a memory 402, and a program is stored in the memory 402, and the program is loaded by the processor 401 and controls the cleaning module 300 of the cleaning device 100 to perform a self-cleaning operation.

[0066] The cleaning device 100 may be, but is not limited to, an autonomous cleaning device such as a mopping robot, a floor washing robot, a sweeping and mopping integrated machine, or the cleaning device 100 may also be a semi-autonomous cleaning device such as a handheld floor washer.

[0067] Reference Figure 1 , Figure 2 , in some embodiments, during the self-cleaning process, the liquid supply component 102 can provide cleaning liquid to inject the cleaning liquid required when cleaning the mopping member 101, and the cleaning liquid includes, but is not limited to, clean water, detergent, cleaning liquid and their combinations; the liquid supply component 102 includes a liquid storage tank 1021 for storing cleaning liquid, a heater 1022 for heating the cleaning liquid, a water pump 1023 and a sprayer 1024.

[0068] Specifically, pipelines are connected between the water pump 1023 and the heater 1022 and between the heater 1022 and the sprayer 1024, and the cleaning liquid flows to the mopping member 101 through the pipelines; the water pump 1023 can input the cleaning liquid in the liquid storage tank 1021 into the heater 1022 through the pipelines for heating; the heater 1022 can be, but is not limited to, a heating pot or a heating plate, etc. After the cleaning liquid is heated by the heater 1022, the cleaning liquid is then input into the sprayer 1024 through the pipelines, and the sprayer 1024 injects the heated cleaning liquid towards the mopping member 101, so that the cleaning device 100 can wash the mopping member 101 with hot water, improve the cleaning effect, inhibit the growth of bacteria, and achieve a deodorizing effect.

[0069] It can be understood that the liquid supply component 102 is electrically connected to the control module 400, and the liquid supply component 102 can inject hot water into the mopping member 101 under the control of the control module 400.

[0070] In some embodiments, the scrubbing member 101 is a rotary brush, and the cleaning module 300 further includes a driving assembly 104 for driving the rotary brush to rotate. The driving assembly 104 is electrically connected to the control module 400, and the driving assembly 104 drives the rotary brush to rotate under the control of the control module 400. A scraping strip 1025 is further provided on the sprayer 1024. The scraping strip 1025 is strip-shaped and arranged parallel to the rotary brush; the scraping strip 1025 can be made of a silicone material and has a certain flexibility; at least the surface material of the rotary brush is a material with water absorption / adsorption function such as cotton cloth or cloth strip. Then, during the contact between the scraping strip 1025 and the rotary brush, the rotary brush can be squeezed and the sewage can be scraped off.

[0071] Reference Figure 3 , in some embodiments, the cleaning device 100 further includes a sewage tank 500 and a sewage recovery pipe 600. One end of the sewage recovery pipe 600 is connected to the sewage tank 500, and the sewage recovery pipe 600 forms a suction port at the scrubbing member 101; the suction assembly 103 can provide a suction force to create a negative pressure inside the cleaning device 100, so that the sewage in the cleaning tank 202 flows into the sewage tank 500 through the sewage recovery pipe 600 under the action of the negative pressure; and, the sewage tank 500 can be detached from the cleaning device 100 to facilitate the separate cleaning of the sewage tank 500. The suction assembly 103 is electrically connected to the control module 400, and the suction assembly 103 can operate under the control of the control module 400 to enable the cleaning device 100 to suck the sewage in the cleaning tank 202 into the sewage tank 500.

[0072] Reference Figure 6 , it can be understood that the control module 400 is the control core of the cleaning device 100. The control module 400 can be the control circuit board or control chip of the cleaning device 100; specifically, the control module 400 can be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a single-chip microcomputer, an ARM (Acorn RISC Machine) or other programmable logic devices, discrete gate or transistor logic, discrete hardware components or any combination of these components.

[0073] The control module 400 can receive the self-cleaning start instruction of the cleaning device and control the cleaning module 300 of the cleaning device 100 to perform a self-cleaning operation.

[0074] Exemplarily, the self-cleaning start instruction can be generated based on the user's activation action on a button, a control panel or a touch screen provided on the body of the cleaning device 100.

[0075] Alternatively, the control module 400 further includes a wireless module, and the cleaning device 100 communicates wirelessly with an external device through the wireless module. This enables the user to send a self-cleaning start instruction to the cleaning device 100 through the external device. After the wireless module receives this instruction, the control module 400 can control the cleaning module 300 to perform a self-cleaning operation; the external device may specifically be, but not limited to, terminal devices such as a remote control, a smartphone, a tablet computer, etc.

[0076] Please refer to Figure 5 、 Figure 6 , this application provides the self-cleaning method for the above-mentioned cleaning device 100, and this self-cleaning method includes the following steps:

[0077] S1: In response to the self-cleaning start instruction, the cleaning device 100 determines whether the cleaning device 100 meets the preset self-cleaning working conditions;

[0078] It can be understood that after the control module 400 of the cleaning device 100 receives the self-cleaning start instruction, the cleaning device 100 will not immediately enter the self-cleaning mode for cleaning the mopping member 101. Instead, it first detects the cleaning device to determine whether the current state of the cleaning device 100 meets the preset self-cleaning working conditions, which can prevent problems from occurring in the cleaning device 100 during the self-cleaning mode; among them, the preset self-cleaning working conditions are written in the program of the memory 402.

[0079] In some embodiments, referring to Figure 6 , determining whether the cleaning device 100 meets the preset self-cleaning working conditions includes: First, detecting whether the cleaning device 100 is docked with the charging base station 200. If it is detected that the cleaning device 100 is not on the charging base station 200, the cleaning device 100 will not be able to enter the self-cleaning mode; it is necessary to detect that the cleaning device 100 is successfully docked with the charging base station 200.

[0080] Secondly, the preset self-cleaning working conditions further include, but are not limited to: detecting whether there is cleaning liquid stored in the liquid storage tank 1021; detecting whether the heater 1022 can operate normally; detecting whether the water pump 1023 can operate normally; detecting whether the suction assembly 103 can operate normally; detecting whether the sewage tank 500 in the cleaning device 100 is installed in place; detecting whether the drive assembly 104 can normally drive the rotary brush to rotate. And only after detecting and determining that the cleaning device 100 fully meets the above self-cleaning working conditions, the cleaning device 100 can enter the self-cleaning mode; if it is detected that the cleaning device 100 fails to meet any of the above working conditions, the cleaning device 100 will not be able to enter the self-cleaning mode; this can avoid problems such as sewage overflow and poor cleaning effect when the cleaning device 100 makes mistakes during the self-cleaning process after entering the self-cleaning mode.

[0081] And during the above detection process, there is no need for an operator to perform manual detection. Instead, the cleaning device 100 automatically completes the self-detection, making the device more efficient and intelligent in use.

[0082] In some embodiments, the cleaning device 100 is equipped with a voice module. When it is detected that the cleaning device 100 is not on the charging base 200, the voice module can remind the user to dock the cleaning device 100 with the charging base 200 for self-cleaning through voice; or when it is detected that a specific component of the cleaning module 300 is malfunctioning, the voice module reminds the user through voice which specific component is not working currently. The device has a high degree of intelligence and can promptly identify the problem of the device when the device is abnormal.

[0083] In some embodiments, referring to Figure 3 , a self-cleaning button 1001 is provided on the body of the cleaning device 100. When the user presses the self-cleaning button 1001, a self-cleaning start instruction can be sent to the cleaning device 100, making the operation convenient and fast.

[0084] S2: When the cleaning device 100 determines that the self-cleaning working conditions are met, the cleaning device 100 enters the self-cleaning mode. The cleaning device 100 supplies cleaning liquid to the mopping member 101 through a pipeline to clean the mopping member 101 of the cleaning device 100 within a preset first time period. The cleaning liquid is heated to a preset temperature during the process of flowing through the pipeline.

[0085] Specifically, in the self-cleaning mode, the water pump 1023 of the cleaning device 100 operates to divert the cleaning liquid in the liquid storage tank 1021 to the heater 1022 through a pipeline, so that the cleaning liquid at room temperature is heated to a preset temperature under the action of the heater 1022, where the range of the preset temperature is 50° - 80°, and specifically it can be 50°, 60°, 70°, 80°, etc. When the cleaning liquid is heated to the preset temperature by the heater 1022, the water pump 1023 further diverts the heated cleaning liquid to the sprayer 1024 through a pipeline. The heated cleaning liquid is rinsed on the mopping member 101 through the sprayer 1024. By heating the cleaning liquid by the cleaning device 100 and using the heated cleaning liquid to clean the roller brush, the growth of bacteria can be inhibited and the deodorization effect can be achieved; and the cleaning liquid can smoothly flow to the heater 1022 and the sprayer 1024 through the pipeline in the cleaning device 100, with smooth diversion to ensure the liquid output.

[0086] In some embodiments, the scrubbing member 101 is specifically a roller brush, and the driving assembly 104 can drive the scrubbing member 101 to roll; when the cleaning device 100 enters the self-cleaning mode, the driving assembly 104 drives the scrubbing member 101 to rotate under the control of the control module 400, so that while the cleaning device 100 rinses the roller brush with the cleaning liquid, the scrubbing member 101 rolls at the same time, which can uniformly clean the scrubbing member 101 and has a good cleaning effect.

[0087] Moreover, a squeegee 1025 is provided on the sprayer 1024. The squeegee 1025 is strip-shaped and arranged parallel to the roller brush and in contact with the roller brush; the squeegee 1025 can be made of silica gel material and has a certain flexibility; during the self-cleaning process, when the squeegee 1025 contacts the rolling roller brush, the squeegee 1025 can squeeze the roller brush and scrape off sewage or stains from the roller brush, making the cleaning of the roller brush cleaner.

[0088] Specifically, the range of the first duration is 30s - 60s to avoid too short a cleaning duration. The first duration is preferably 40s, that is, the cleaning device 100 will continuously rinse the scrubbing member 101 with the cleaning liquid for 40s, and preferably clean the scrubbing member 101.

[0089] In some embodiments, before the cleaning device 100 provides the cleaning liquid to clean the scrubbing member 101 of the cleaning device 100 within a preset first duration, it further includes: within a preset second duration, driving the scrubbing member 101 of the cleaning device 100 to rotate and simultaneously controlling the cleaning device 100 to recover the sewage in the charging base 200.

[0090] It can be understood that after the cleaning device 100 has just completed floor cleaning and is placed on the tray 201 of the charging base 200, the scrubbing member 101 is in a relatively wet state at this time, and the scrubbing member 101 will continuously leak sewage into the cleaning tank 202 of the tray 201; and because the floor has just been cleaned, the sewage leaked from the scrubbing member 101 is in a relatively dirty state.

[0091] Therefore, before the cleaning device 100 provides cleaning liquid to clean the mopping member 101, the cleaning device 100 will first drive the mopping member 101 to roll through the driving assembly 104 to spin-dry the mopping member 101 to a certain extent, so that the sewage on the mopping member 101 can be thrown out into the cleaning tank 202 on the tray 201. At the same time, the cleaning device 100 operates the suction assembly 103 to recover the sewage thrown into the cleaning tank 202. Since the mopping member 101 is relatively dirty just after the cleaning device 100 finishes cleaning the ground, the sewage leaked from the mopping member 101 at this time is relatively dirty. If this sewage remains in the cleaning tank 202 all the time; during the subsequent cleaning process of the mopping member 101, the mopping member 101 is always soaked in this sewage, resulting in poor cleaning effect; therefore, the mopping member 101 is driven to roll in advance to initially throw out the relatively dirty sewage and recover this part of the sewage, so as to improve the subsequent cleaning effect of the mopping member 101 and improve the cleaning efficiency.

[0092] In some embodiments, the preset second duration is 5 s, that is, before the cleaning device 100 uses the cleaning liquid to clean the mopping member 101, the mopping member 101 is driven to rotate continuously for 5 s to throw out the sewage, and the suction assembly 103 is started to recover the thrown sewage.

[0093] S3: After the cleaning device 100 finishes cleaning the mopping member 101 for the first duration, the cleaning device 100 recovers the sewage in the charging base station 200.

[0094] Specifically, after the mopping member 101 is cleaned for the first duration with the cleaning liquid, the water pump 1023 and the heater 1022 are turned off to stop supplying liquid to the mopping member 101; then the suction assembly 103 is started, and the suction assembly 103 will provide suction to suck the sewage in the cleaning tank 202 into the sewage recovery pipe 600 from the suction port of the sewage recovery pipe 600, and the sewage flows through the sewage recovery pipe 600 into the sewage tank 500.

[0095] Specifically, the suction assembly 103 operates continuously for 30 s to better recover all the sewage in the cleaning tank 202.

[0096] S4: The cleaning device 100 repeatedly executes step S2 and step S3 until a preset exit condition is met.

[0097] Understandably, in step S2, the cleaning device 100 uses a cleaning liquid to clean the mopping member 101. In step S3, the cleaning device 100 recovers the sewage in the cleaning tank 202 of the tray 201. That is, the cleaning device 100 completes one cleaning of the mopping member 101 by sequentially performing step S2 and step S3 once. Therefore, for the preset first number of cycles, the cleaning device 100 repeats step S2 and step S3 according to the first number of cycles, so that the cleaning device 100 can perform multiple repeated cleaning operations on the mopping member 101, improving the cleaning effect of the mopping member 101.

[0098] In some embodiments, the first number of cycles is 3 times, that is, the cleaning device 100 performs 3 cycles of cleaning on the mopping member 101, and can preferably clean the mopping member 101.

[0099] In some embodiments, the cleaning device 100 detects the degree of dirt of the sewage recovered for the last time, and judges whether the preset exit condition is satisfied according to the degree of dirt of the sewage recovered for the last time.

[0100] Specifically, the cleaning device 100 further includes a sewage detection component 105, and the sewage detection component 105 can detect the dirt value of the sewage recovered by the cleaning device 100. After the cleaning device 100 finishes cleaning the mopping member 101 according to the preset first number of cycles, the sewage detection component 105 is used to detect the dirt value of the sewage recovered by the cleaning device 100 in the last cleaning. Then, by judging whether this dirt value is greater than the preset dirt threshold, it is judged whether the cleaning device 100 meets the preset exit condition, and the dirt threshold is a value set in advance according to the cleaning requirements.

[0101] Specifically, if the detected dirt value is less than the dirt threshold, it means that the cleaning device 100 meets the preset exit condition, the mopping member 101 meets the cleaning requirements, and has been cleaned. The cleaning device 100 turns off each operating component to exit the self-cleaning mode.

[0102] In some embodiments, if the detected dirt value is greater than or equal to the dirt threshold, it means that the mopping member 101 is still not cleaned, and the cleaning device 100 does not meet the preset exit condition. Then, the control module 400 will control the cleaning device 100 to repeat step S2 and step S3 according to the preset second number of cycles to perform multiple cyclic cleanings on the mopping member 101 again, that is, clean the mopping member 101 again. Specifically, the second number of cycles is 2 times. Until the dirt value of the sewage recovered by the cleaning device 100 for the last time is less than the dirt threshold, the cleaning device 100 meets the exit condition, and the cleaning device 100 will turn off each operating component to exit the self-cleaning mode, thereby ensuring that the mopping member 101 is cleaned when exiting the self-cleaning mode.

[0103] In some embodiments, when the detected dirt value is greater than or equal to the dirt threshold, the cleaning device can identify the dirt value of the sewage and automatically generate the third number of cycles. The control module 400 will control the cleaning device 100 to repeat steps S2 and S3 according to the generated third number of cycles to clean the mopping member 101 repeatedly for multiple times. Moreover, the third number of cycles is positively correlated with the dirt value. If the dirt value is relatively large, indicating that the sewage is still dirty, the generated third number of cycles will also be relatively large, which can be 3 or 4 times, so as to clean the mopping member 101 for a relatively large number of cycles. If the dirt value is relatively small, indicating that the sewage is not very dirty, the third number of cycles will be relatively small, which can be 1 or 2 times, so that the mopping member 101 can be cleaned by cycling a smaller number of times. Then, after repeatedly cleaning the mopping member 101 according to the third number of cycles, the dirt value of the finally recovered sewage is basically less than the dirt threshold, enabling the cleaning device 100 to meet the exit condition. The third number of cycles can be adaptively generated according to the dirt value of the sewage, enabling the cleaning device 100 to clean the mopping member 101 within a reasonable number of cycles and save power.

[0104] The cleaning device 100 can determine that the mopping member 101 is cleaned by comparing the dirt value of the sewage with the preset dirt threshold; if the sewage is not clean enough, the cleaning device 100 will repeat the cyclic cleaning of the mopping member 101 again to ensure that the mopping member 101 can be cleaned and the cleaning effect is good.

[0105] In some embodiments, referring to Figure 4 , the sewage detection component 105 includes an infrared emitting tube 1051 and an infrared receiving tube 1052 installed in the sewage recovery pipe 600; the steps for the sewage detection component 105 to detect the dirt value of the sewage recovered by the cleaning device 100 are as follows: the infrared emitting tube 1051 emits infrared rays, the infrared rays pass through the sewage in the sewage recovery pipe 600 and are received by the infrared receiving tube 1052, and the infrared receiving tube 1052 generates a voltage value after receiving the infrared rays, and the cleaning device 100 determines the dirt value according to the voltage value.

[0106] Understandably, the infrared emitting tube 1051 and the infrared receiving tube 1052 are respectively arranged on opposite sides of the sewage recovery pipe 600, so that infrared rays can better pass through the sewage in the sewage recovery pipe 600. If the sewage in the sewage recovery pipe 600 is relatively dirty, then the infrared rays emitted by the infrared emitting tube 1051 and passing through the sewage in the sewage recovery pipe 600 will decrease when entering the infrared receiving tube 1052. After the infrared receiving tube 1052 receives light with different powers, different reverse currents will be generated, and finally a corresponding analog voltage value will be obtained. The cleaning device 100 determines the current dirtiness level according to the difference in the analog voltage value, and uses infrared rays to detect the dirtiness value of the sewage. The detection method is reasonable and accurate, and can effectively detect the dirtiness value of the sewage in the sewage recovery pipe 600.

[0107] In the self-cleaning method of the present application, the cleaning device 100 realizes a fully automatic self-cleaning process for the mopping member 101. The cleaning device 100 can determine whether it meets the self-cleaning working conditions to enter the self-cleaning mode; and the cleaning device 100 can heat the cleaning liquid to clean the mopping member 101 and cycle the cleaning multiple times according to a preset number of times, which can better clean the mopping member 101; finally, it is determined whether the cleaning device 100 exits the self-cleaning mode or continues to clean according to the dirtiness degree of the recovered sewage, ensuring that the mopping member 101 is cleaned; the entire self-cleaning process is highly intelligent, and can realize efficient and comprehensive cleaning operations of the cleaning device, and its self-cleaning method is simple and efficient. In addition, during the entire process of cleaning the mopping member 101, each operation of providing the cleaning liquid, heating the cleaning liquid, and recovering the sewage in the cleaning tank 202 is completed by the cleaning device 100 itself. The charging base station 200 only plays a role in supporting the cleaning device 100, and the cleaning device 100 itself has complete functionality.

[0108] The above are only the preferred embodiments of the present application, and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
