[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0049] The present invention provides a cleaning system, referring to Figures 1 to 3 The cleaning system 100 includes a cleaning robot 10 and a cleaning base station 20. The cleaning robot 10 is docked with the cleaning base station 20. The cleaning base station 20 is used to maintain the cleaning robot 10, such as charging or injecting water into the cleaning robot 10. The cleaning robot 10 may be a mopping robot, a sweeping robot, or a stain removal robot. For the sake of convenience, the cleaning robot 10 mentioned below is described by taking a mopping robot as an example.

[0050] Among them, the cleaning robot 10 is provided with a water storage chamber 101, a water inlet 102 and a drainage channel 103. The water inlet 102 is connected to the water storage chamber 101. One end of the drainage channel 103 is open to form a drainage inlet 1031. The drainage inlet 1031 is arranged in the water storage chamber 101 and is higher than the preset liquid level of the water storage chamber 101. The other end of the drainage channel 103 is open to form a drainage outlet 1032.

[0051] It should be noted that when the water storage chamber 101 is full of water, the highest level of the liquid is the preset liquid level.

[0052] The cleaning base station 20 is provided with a cleaning tank 201 and a water injection port 202. The water injection port 202 can be located above the bottom of the cleaning tank 201. The water injection port 202 is docked with the water inlet 102. The cleaning tank 201 is for placing the cleaning component 105 of the cleaning robot 10. The cleaning base station 20 is used to inject water into the water storage chamber 101 when the water injection port 202 is docked with the water inlet 102. The drainage channel 103 is used to overflow water from the water storage chamber 101 and discharge it to the cleaning tank 201 when the water level in the water storage chamber 101 is higher than the drainage inlet 1031.

[0053] In this way, water is automatically injected into the water storage chamber 101 through the cleaning base station 20, and when the water level in the water storage chamber 101 is higher than the drainage inlet 1031, water flows in from the drainage inlet 1031 and flows out from the drainage outlet 1032. On the one hand, the amount of water in the water storage chamber 101 can meet the demand for water supply to the cleaning component 105. On the other hand, water continues to be injected when the water storage chamber 101 is full, so that the water in the water storage chamber 101 can overflow out of the water storage chamber 101, and the overflowed water is discharged to the cleaning component 105 or accumulated in the cleaning tank 201, so as to be able to soak the cleaning component 105. In this way, water is injected into the cleaning tank 201. Compared with the previous method of directly injecting water into the cleaning tank through the base station, the cleaning base station 20 in the present application does not need to be equipped with too many pump body structures and pipelines. It only needs to use the water pump 2043 (one) of the base station to realize automatic water injection in the cleaning tank 201, thereby providing water for the cleaning component 105 to achieve self-cleaning. Such a setting not only has a simple structure, but also simplifies the pipeline setting, and can greatly reduce costs, greatly improving the practical performance of the cleaning system 100.

[0054] Reference Figures 1 to 7 The cleaning robot 10 includes a robot body 1, a water storage shell 2, a cover body 3 and a drainage pipe body 4. The robot body 1 is provided with a driving device (not shown in the figure) for installing the water storage shell 2 and the cover body 3. The driving device is used to drive the cleaning component 105 to rotate or reciprocate relative to the robot body 1. The water storage shell 2 is installed in the robot body 1. The water storage shell 2 is provided with a water storage tank 21. The cover body 3 is fixedly and sealedly connected to the water storage shell 2 and covers the notch of the water storage tank 21 to form a water storage chamber 101. The cover body 3 is penetrated by a water inlet 102. When the robot body 1 is docked with the cleaning base station 20, the water inlet 102 is connected to the water injection port 202 by pipeline.

[0055] Among them, the driving device can be a rotating motor, and the cleaning component 105 can be a cleaning roller, which is coaxially fixedly connected to the rotating motor; or, the driving device includes a rotating motor and a rocker structure, the cleaning component 105 can be a mop component, and the rotating motor is used to be connected to the mop component through the rocker structure to make the mop component reciprocate.

[0056] The drainage pipe body 4 is formed with a drainage channel 103, and the drainage pipe body 4 is connected to the water storage shell 2. The drainage pipe body 4 is at least partially arranged in the water storage shell 2, and the other part extends out of the water storage shell 2. In this way, it can be adaptively adjusted according to the internal structural space of the cleaning robot 10, thereby facilitating installation and use, as long as water can be filled into the cleaning tank 201. Among them, the drainage pipe body 4 can be integrally formed with the water storage shell 2, and is also sealed and assembled at the beginning.

[0057] It is understandable that the drainage pipe body 4 can also be disposed as a whole in the water storage shell 2, and one end of the drainage pipe body 4 is connected to the bottom of the water storage tank 21 and is integrally formed with the water storage shell 2, which is convenient for processing and reduces the difficulty of installation. The drainage channel 103 also penetrates the bottom of the water storage tank 21 to communicate with the external space. In the embodiment of the present application, the drainage pipe body 4 is disposed as a whole in the water storage shell 2 as an example, which is only an example and is not limited here.

[0058] The cover body 3 is also provided with a water supply port 104 connected to the water storage chamber 101, and the cleaning component 105 is provided with a water inlet 1051. The cleaning robot 10 may also include a peristaltic pump 106. The input end of the peristaltic pump 106 is connected to the water supply port 104 by a pipeline, and the output end of the peristaltic pump 106 is connected to the water inlet 1051 by a pipeline. The peristaltic pump 106 is used to pump the water 2043 in the water storage chamber 101 to the cleaning component 105, so as to provide water for the cleaning component 105 during the mopping process of the cleaning robot 10, so as to realize intelligent cleaning operations and improve the cleaning effect of mopping.

[0059] Among them, two limiting grooves 31 are also provided on the surface of the cover body 3 facing away from the water storage shell 2, and the two limiting grooves 31 are used for installing pipelines connected to the water inlet 102 or the water supply port 104. The two limiting grooves 31 are used to limit the corresponding pipelines so that the pipelines can be stably installed on the cover body 3 to avoid loosening from the water inlet 102 or the water supply port 104, thereby improving the waterproof performance.

[0060] In addition, when the cleaning operation is not being performed, when the cleaning robot 10 is maintaining the cleaning base station 20, the peristaltic pump 106 can automatically inject water into the cleaning component 105, and the cleaning component 105 rotates to rub or squeeze with the cleaning component 205 of the cleaning base station 20. In this way, the self-cleaning of the cleaning component 105 can be achieved. Self-water supply can be achieved without the cleaning base station 20 providing water to the cleaning component 105, so that the cleaning component 105 can clean itself.

[0061] Continue to refer to Figures 1 to 7 The cleaning robot 10 also includes a controller and a pair of conductive members 5 electrically connected to the controller. The pair of conductive members 5 are arranged higher than a preset liquid level of the water storage chamber 101. When the water in the water storage chamber 101 exceeds the preset liquid level and contacts the pair of conductive members 5, the controller generates a water full signal and sends the water full signal to the cleaning base station 20, so that the cleaning base station 20 stops or continues to inject water into the water storage chamber 101 according to the water full signal.

[0062] The cleaning base station 20 injects water into the water storage chamber 101. After the water level of the water storage chamber 101 reaches the full state, the pair of conductive members 5 can contact the water in the water storage chamber 101. After the pair of conductive members 5 contact the water, the controller generates a full water signal and sends the full water signal to the cleaning base station 20. The cleaning base station 20 receives the full water signal and stops injecting water into the water storage chamber 101 when it is not necessary to continue injecting water. If the cleaning robot 10 is to perform a self-cleaning task, the cleaning base station 20 continues to inject water into the water storage chamber 101, so that the water in the water storage chamber 101 overflows into the cleaning component 105 or the cleaning tank 201.

[0063] With such a configuration, the water level of the water storage chamber 101 can be flexibly detected through a pair of conductive members 5. If the self-cleaning task is not required, water injection into the water storage chamber 101 can be stopped, effectively avoiding the waste of water resources when the self-cleaning task is not required, thereby saving water. The water fullness of the water storage chamber 101 can also be known through a pair of conductive members 5, so that the volume of water to be continuously injected into the water storage chamber 101 can be more accurately selected, avoiding the waste of water resources and increased electricity costs caused by excessive injection of water.

[0064] Continue to refer to Figures 1 to 7 The pair of conductive members 5 includes two electrode sheets 51, each of which is provided with a triggering portion 511. The cover body 3 is penetrated with two installation holes 32 arranged at intervals. One end of the two triggering portions 511 passes through the corresponding installation holes 32 to extend into the water storage chamber 101. The drainage inlet 1031 is arranged higher than the two triggering portions 511 in the vertical direction. This arrangement is to ensure that when the water storage chamber 101 is full of water, the water in the water storage chamber 101 will not overflow the drainage inlet 1031, that is, the water will not overflow out of the water storage chamber 101.

[0065] It can be understood that one of the two electrode sheets 51 is the anode sheet, and the other electrode sheet 51 is the cathode sheet. When the water storage chamber 101 is full of water, both the anode sheet and the cathode sheet are in contact with the water, thereby forming an energized circuit, that is, a triggered state occurs, so that the main control board can send a water-full signal to the cleaning base station 20, and the cleaning base station 20 performs corresponding subsequent actions after receiving the water-full signal.

[0066] Due to the high fluid velocity, the speed of responding to the trigger signal of water fullness must be timely, otherwise the cleaning base station 20 will continue to inject water into the water storage chamber 101 after the water is full, which may easily cause water overflow and affect the user experience. Therefore, the two electrode sheets 51 cannot be separated too far, and the two electrode sheets 51 are arranged as close as possible to shorten the time of forming the power-on circuit, so that the cleaning base station 20 can stop supplying water to the water storage chamber 101 in time.

[0067] The two electrode sheets 51 are arranged on the cover body 3, and the trigger part 511 is located at the top of the water storage chamber 101. In this way, after the water level in the water storage chamber 101 drops, the water droplets attached to the two electrode sheets 51 fall down due to the influence of gravity, so that the liquid retained on the two electrode sheets 51 is as small as possible. The purpose of such a setting is to avoid the situation where the water full state is mistakenly triggered due to the small distance between the two electrode sheets 51 and water droplets are easily retained, thereby improving the accuracy of triggering the water full signal.

[0068] A pair of conductive parts 5 can also be triggers or trigger sheets, or a pair of conductive parts 5 can also be other electronic components with trigger functions, as long as it can form an electrical circuit when the water level in the water storage chamber 101 reaches a full state, it will not be described in detail here.

[0069] Continue to refer to Figures 1 to 7 The cleaning robot 10 further includes a one-way valve 6, which is disposed at the drainage outlet 1032. The one-way valve 6 is used to restrict the flow of liquid or gas from the drainage inlet 1031 to the drainage outlet 1032. The one-way valve 6 is used to restrict the flow of liquid or gas only from the drainage inlet 1031 to the drainage outlet 1032. In this way, when the cleaning base station 20 injects water into the water storage chamber 101, the air can be exhausted to the outside through the exhaust channel, so that the air pressure in the water storage chamber 101 is roughly consistent with the air pressure of the outer package, so that the cleaning base station 20 can smoothly inject water into the water storage chamber 101. In addition, it can also prevent the water overflowing from the water storage chamber 101 from flowing back to the water storage chamber 101, effectively reducing the phenomenon of water leakage and improving the waterproof performance.

[0070] In some embodiments, the one-way valve 6 can be a diaphragm pressure valve made of silicone material and arranged in an umbrella shape. The water in the water storage chamber 101 overflows into the drainage channel 103 and acts on the diaphragm pressure valve to force the diaphragm pressure valve to open, or it can be other valve bodies that only allow one-way flow, which will not be described in detail here.

[0071] Reference Figure 2 , Figures 5 to 7 The cleaning robot 10 further includes a sealing member 7. The drainage pipe body 4 is disposed in the water storage shell 2. One end of the drainage pipe body 4 is connected to the bottom of the water storage tank 21. The drainage channel 103 passes through the bottom of the water storage tank 21. The sealing member 7 is connected to the side of the water storage shell 2 away from the bottom of the water storage tank 21. The sealing member 7 is used to press the one-way valve 6 against the water storage shell 2 to seal the gap between the one-way valve 6 and the water storage shell 2, thereby improving the waterproof performance of the cleaning robot 10.

[0072] The sealing member 7 is provided with a transition chamber 711 with one end being open and a diversion port 712 communicating with the transition chamber 711. The transition chamber 711 is arranged in alignment with the drainage outlet 1032. The one-way valve 6 blocks the drainage outlet 1032 and the transition chamber 711. The diversion port 712 is used to divert and drain water when the drainage outlet 1032 is connected to the transition chamber 711. With such an arrangement, when water in the water storage chamber 101 overflows, the transition chamber 711 can be used for buffering, and the water can be diverted and drained to the cleaning tank 201 through the diversion port 712, thereby effectively avoiding the phenomenon of unstable drainage caused by splashing of overflowed water, so that the overflow flows into the cleaning tank 201, rationally utilizing water resources and avoiding waste.

[0073] The sealing member 7 includes a sealing body 71, which can be arranged in a columnar or square shape, or in any other shape. The sealing body 71 is provided with a groove body to form a transition cavity 711 with an open end, and the side wall of the sealing body 71 is also penetrated by a hole body connected to the transition cavity 711 to form a guide port 712.

[0074] Reference Figures 8 to 12 The cleaning base station 20 includes a base station body 203, a water injection assembly 204 and a cleaning assembly 205. The base station body 203 is provided with a cleaning tank 201 and a water injection port 202. The water injection assembly 204 is arranged on the base station body 203 and is connected to the water injection port 202 by a pipeline. The water injection assembly 204 is used to inject water into the water storage chamber 101. The cleaning assembly 205 is arranged in the cleaning tank 201 and is used to clean the cleaning assembly 105.

[0075] The base station body 203 includes a base 2031, a bracket 2032 and a cleaning tray 2033. The bracket 2032 is provided for the water injection assembly 204 to be installed. The bracket 2032 can be detachably installed on the base 2031. The base 2031 is provided with a return position 2034 for accommodating the cleaning robot 10. The cleaning tray 2033 can be detachably placed at the bottom of the return position 2034. The water injection port 202 is formed on the wall of the return position 2034. A groove body is provided on the surface of the cleaning tray 2033 to form a cleaning groove 201. The cleaning assembly 105 is installed at the bottom of the cleaning groove 201.

[0081] The present invention proposes a self-cleaning method, which is applied to a cleaning system, referring to Fig.13 , the self-cleaning method comprises the following steps:

[0082] S1: The cleaning robot is docked with the cleaning base station, and the cleaning component of the cleaning robot is placed in the cleaning tank and abuts against the cleaning component;

[0083] S2: The cleaning base station injects water into the water storage chamber;

[0084] S3: The cleaning robot detects the water level in the water storage chamber, and sends a water full signal to the cleaning base station after the water level in the water storage chamber reaches a preset water level threshold;

[0085] S4: The cleaning base station receives the water full signal and continues to inject water into the water storage chamber at a preset time threshold or a preset flow threshold. The water in the water storage chamber flows in from the drainage inlet and overflows from the drainage outlet for the cleaning component to perform self-cleaning.

[0086] In step S1, the cleaning robot is docked with the cleaning base station. It can be understood that the cleaning robot is electrically connected to the cleaning base station, the water inlet of the cleaning robot is connected to the water inlet pipeline of the cleaning base station, and the cleaning component, such as a mop component or a cleaning roller component, is placed on the cleaning tray and abuts against the cleaning component.

[0087] In step S2, the water pump works and transports the water in the water tank to the water storage chamber of the cleaning robot through the water filling pipe, so as to automatically fill the cleaning robot with water.

[0088] In step S3, the cleaning robot detects whether the water level in the water storage chamber is full through two electrode sheets. After the water level in the water storage chamber reaches the preset water level threshold, that is, the water level in the water storage chamber is full, the two electrode sheets come into contact with the water to form an energized circuit, and the cleaning robot sends a full water signal to the cleaning base station through the main control board.

[0089] In step S4, the cleaning base station receives a water-full signal and learns the water level in the water storage chamber to reach a water-full state. When the cleaning robot needs to perform a self-cleaning task, the cleaning base station controls the water pump to continue to inject water into the water storage chamber, and continues to inject water into the water storage chamber at a preset time threshold or a preset flow threshold, so that the water level in the water storage chamber is higher than the drainage inlet, and the water in the water storage chamber flows in from the drainage inlet and overflows from the drainage outlet, and the overflowed water accumulates in the cleaning tank to soak the cleaning components. Among them, the preset time threshold or the preset flow threshold can be determined according to the capacity of the water storage chamber. When the water storage chamber is full, inject an appropriate amount of water to avoid wasting water resources.

[0090] After step S4, the self-cleaning method further comprises the following steps:

[0091] S5: the cleaning component rotates and rubs against the washing component, and the washing component cleans the cleaning component;

[0092] S6: After the cleaning component cleans the cleaning component, the suction component sucks the sewage in the cleaning tank;

[0093] S7: After the suction component sucks the sewage in the cleaning tank, the air-drying component air-dries the cleaning component.

[0094] In step S6, the air pump works and sucks the sewage in the cleaning tank through the suction pipe. During this process, the air pump works until all the sewage in the cleaning tank is sucked out.

[0095] In step S7, the fan operates to dry the cleaning tank and the cleaning components through the air duct.
