[0002] For household cleaning systems, after the robot completes sweeping and mopping operations, it will return to the base station to automatically clean its roller brush and mop. After the robot self-cleans in the base station, there are two main ways to discharge sewage: one is that the air pump in the base station first vacuums the sewage tank, and the sewage is sucked into the sewage tank through the negative pressure of the sewage tank, and the user needs to manually pour out the sewage; the other is to discharge the sewage into the sewer through the automatic water supply and drainage module. Since the sewage pump in the automatic water supply and drainage module has no self-priming ability, it is also necessary to use an air pump to vacuum the sewage tank in the automatic water supply and drainage module, and then discharge the sewage into the sewer through the sewage pump at the bottom. It can be seen that the current sewage discharge method of the base station is complex in structure, and both require the installation of an air pump and a sewage tank, and the base station is relatively large in size.

[0038] The embodiment of the present disclosure provides a cleaning system, including a cleaning and base station. The base station includes a base, a sewage discharge assembly, wherein the base is provided with a sewage discharge port; the sewage discharge assembly is arranged on the base, and the sewage discharge assembly includes a pump unit, a sewage suction pipe and a sewage discharge pipe, the liquid inlet side of the pump unit is configured to be connected to the sewage discharge port through the sewage suction pipe, and the liquid discharge side of the pump unit is connected to the sewage discharge pipe; the pump unit has an internal cavity, and the pump unit is configured to start and generate negative pressure when there is liquid in the internal cavity, so as to pump out the sewage flowing into the sewage discharge port.

[0039] In the cleaning system disclosed herein, the pump unit is configured to be started when there is liquid in the internal cavity, so that the pump unit can generate negative pressure, thereby sucking sewage into the pump unit through the sewage suction pipe, and then discharging the sewage from the sewage discharge pipe through the pump unit. The cleaning system disclosed herein enables the pump unit to have self-priming ability, so that when the pump unit is started, its internal cavity can generate negative pressure to smoothly pump out the sewage. Compared with the solution of using an air pump and a sewage tank to discharge sewage on the base station in the related art, there is no need to set up a sewage pump, an air pump, and a sewage tank, which can simplify the base station structure and reduce the size of the base station.

[0040] For ease of understanding, refer to Figure 1 to Figure 2, the specific structure and working principle of the cleaning system and base station disclosed in the present invention are explained in detail in combination with an embodiment.

[0041] The cleaning system provided by the embodiment of the present disclosure includes a cleaning device and a base station. The cleaning device may be a handheld cleaning device, such as a handheld cleaning machine, a handheld vacuum cleaner, a handheld floor scrubber, and other handheld cleaning devices known to those skilled in the art. It may also be a sweeping robot, a mopping robot, a sweeping and mopping robot, and the like, which are self-propelled cleaning robots used to clean work surfaces that need to be cleaned, such as floors, sofas, and carpets. The cleaning device of the present disclosure may include at least one of a roller brush and a mop, which may come into contact with the surface to be cleaned, and clean the surface to be cleaned by contact.

[0042] like Figure 1 As shown, in a cleaning system provided by an embodiment of the present disclosure, the base station includes a base 10 and a sewage discharge component 20.

[0043] A sewage outlet 11 may be provided on the base 10 , and a sewage outlet assembly 20 is provided on the base 10 . The sewage outlet assembly 20 includes a pump body unit 21 , a sewage suction pipe 22 and a sewage outlet pipe 23 . The liquid inlet side of the pump body unit 21 is constructed to be connected to the sewage outlet 11 through the sewage suction pipe 22 , and the liquid discharge side of the pump body unit 21 is connected to the sewage outlet pipe 23 .

[0044] The pump unit 21 has an internal cavity, and is configured to start and generate negative pressure when liquid is stored in the internal cavity to pump out the sewage flowing in from the sewage outlet 11. The pump unit 21 of the present disclosure may be a transmission water pump. In a specific embodiment of the present disclosure, the pump unit 21 of the present disclosure is a centrifugal pump.

[0045] The working principle and specific structure of the pump unit 21 are common knowledge for those skilled in the art. It generally includes an internal cavity, blades and other components. When there is no water in the internal cavity of the pump unit 21, the blades cannot form a negative pressure for suction during the rotation process. Therefore, the pump unit 21 of the present invention is constructed to be started when there is liquid in its internal cavity, so that the blades can generate a negative pressure for suction during the rotation process, thereby pumping out the sewage flowing in from the sewage outlet 11. In traditional base stations, a fan assembly is required to form a negative pressure in the sewage tank, so that the sewage is pumped into the sewage tank through the sewage outlet 11 for storage. The solution of the present invention makes it unnecessary to set up a fan assembly for sewage pumping operations. Even in some application scenarios, there is no need to set up a sewage tank, and the sewage flowing into the sewage outlet 11 can be directly discharged through the pump unit 21 of the present invention.

[0046] In one embodiment of the present disclosure, the cleaning system also includes a water supply assembly 30, which is configured to supply water to the internal cavity of the pump body unit 21. The pump body unit 21 is configured to start and generate negative pressure after the water supply assembly 30 is filled with water to pump out the sewage flowing into the sewage outlet 11.

[0047] In the above scheme, the sewage discharge component 20 on the base station includes a pump body unit 21, a sewage suction pipe 22 and a sewage discharge pipe 23. The water supply component 30 on the base station can supply water to the internal cavity of the pump body unit 21, so that before the pump body unit 21 is started, the internal cavity of the pump body unit 21 is first filled with water through the water supply component 30, so that the internal cavity of the pump body unit 21 can generate negative pressure when the pump body unit 21 is started, thereby sucking the sewage into the pump body unit 21 through the sewage suction pipe 22, and then discharging the sewage from the sewage discharge pipe 23 through the pump body unit 21.

[0048] In this way, before the pump body unit 21 is started, water is supplied to the internal cavity of the pump body unit 21 through the water supply assembly 30, so that the internal cavity of the pump body unit 21 is filled with water, so that the pump body unit 21 has self-priming ability, so that when the pump body unit 21 is started, its internal cavity can generate negative pressure to smoothly pump out the sewage. Compared with the solution of using an air pump and a sewage tank to discharge sewage on the base station in the related technology, there is no need to set up a sewage pump and an air pump, which can simplify the base station structure and reduce the size of the base station.

[0049] In one embodiment of the present disclosure, a sewage trough may be provided on the base 10, and a sewage outlet 11 is connected to the sewage trough, and the sewage outlet 11 is used to discharge the sewage in the sewage trough; the base 10 may also be provided with a sewage outlet 11 for docking with a cleaning device, and the sewage outlet 11 is used to discharge the sewage in the sewage bucket inside the cleaning device. The sewage discharge component 20 may be connected to the sewage outlet 11 on the sewage trough, and the sewage discharge component 20 may also be connected to the sewage outlet 11 of the docking cleaning device.

[0050] In one embodiment of the present disclosure, the pump unit 21 may be a centrifugal pump.

[0051] The working principle of a centrifugal pump is to use the rotation of the impeller to make the water centrifugal. A centrifugal pump is a pump that transports liquids by the centrifugal force generated by the rotation of the impeller. A centrifugal pump itself has no self-priming ability and needs to be primed before starting.

[0052] Prime the pump means injecting liquid into the internal cavity and suction pipe before starting the centrifugal pump. Due to the structural characteristics of the centrifugal pump, only when the internal cavity of the pump is filled with liquid and the liquid flows from the center of the impeller to the edge, low pressure can be formed in the center of the impeller and liquid can be sucked in, so generally centrifugal pumps need to be primed before starting.

[0053] The water supply assembly 30 is configured to supply water to the inner cavity of the pump unit 21 before the pump unit 21 is started. In other words, the centrifugal pump is primed by the water supply assembly 30 before the centrifugal pump is started so that the centrifugal pump has self-priming capability when started.

[0054] In one embodiment of the present disclosure, a cleaning tank is further provided on the base 10, the cleaning tank is communicated with the sewage tank, and a flushing port 12 is provided at the cleaning tank, and the flushing port 12 is used to discharge clean water into the cleaning tank to clean the roller brush, the rag or the cleaning tank itself. The water supply assembly 30 is also configured to supply water to the flushing port 12 through the flushing pipe 40, and the water supply assembly 30 is configured to connect the flushing pipe 40 and the pump body unit 21 through the control valve 50, and the control valve 50 is configured to control the passage between the water supply assembly 30 to the pump body unit 21 and the flushing pipe 40.

[0055] The above scheme utilizes the water supply assembly 30 on the base station to distribute clean water to the flushing port 12 and the pump body unit 21, and controls the opening or closing of the passage between the water supply assembly 30 and the flushing port 12, and the opening or closing of the passage between the water supply assembly 30 and the pump body unit 21 through the control valve 50.

[0056] In one embodiment of the present disclosure, Figure 1 As shown, there can be two flushing ports 12, and accordingly, the flushing pipe 40 can be constructed as a main flushing pipe 41 and two branch flushing pipes 42. The main flushing pipe 41 is connected to the water supply assembly 30 through a control valve 50, and the two branch flushing pipes 42 are correspondingly connected to the two flushing ports 12.

[0057] In one embodiment of the present disclosure, the control valve 50 may be a solenoid valve.

[0058] When it is necessary to prime the pump body unit 21, the control board in the base station controls the passage between the water supply assembly 30 and the pump body unit 21 to open through the control valve 50, so that clean water is delivered to the pump body unit 21; when self-cleaning is required, the control board in the base station controls the passage between the water supply assembly 30 and the flushing port 12 to open through the control valve 50, so that clean water is delivered to the flushing port 12.

[0059] In one embodiment of the present disclosure, the control valve 50 is specifically configured to close the passage between the water supply assembly 30 and the pump body unit 21 after the pump body unit 21 is started; and to open the passage between the water supply assembly 30 and the pump body unit 21 before the pump body unit 21 is started.

[0060] Before the pump unit 21 is started, the passage between the water supply assembly 30 and the pump unit 21 is opened to deliver clean water to the pump unit 21 until the internal cavity of the pump unit 21 is filled with water, and then the passage between the water supply assembly 30 and the pump unit 21 is closed. Specifically, in one embodiment of the present disclosure, the control valve 50 is configured to: when the base station performs a self-cleaning operation, control the passage between the water supply assembly 30 and the flushing port 12 to be opened, and the passage between the water supply assembly 30 and the pump unit 21 to be closed, so as to deliver clean water to the flushing port 12; after the self-cleaning operation is completed and before the pump unit 21 is started, control the passage between the water supply assembly 30 and the flushing port 12 to be closed, and the passage between the water supply assembly 30 and the pump unit 21 to be opened, so as to supply water to the pump unit 21; after the pump unit 21 is started, control the passage between the water supply assembly 30 and the flushing port 12 to be closed, and the passage between the water supply assembly 30 and the pump unit 21 to be closed, so that the sewage is pumped out by the pump unit 21.

[0061] In one embodiment of the present disclosure, Figure 1 As shown, the water supply assembly 30 is configured to be connected to the water pipe to supply water to the water guide pipe 24 through the water pipe; and the water supply assembly 30 is configured to be directly connected to the pump body unit 21 through the water guide pipe 24. In one embodiment of the present disclosure, as Figure 1 As shown, the water supply assembly 30 includes a water inlet pipe 31 and a water inlet valve 32 . The water inlet pipe 31 is configured to be connected to a tap water pipe, and the water inlet valve 32 is configured to control the on-off of the water inlet pipe 31 .

[0062] The working process of the base station provided in one embodiment of the present disclosure may be as follows: Figure 1 As shown, the water inlet pipe 31 is directly connected to the tap water, the water inlet valve 32 is opened, and the control valve 50 controls the passage between the water inlet pipe 31 and the flushing port 12 to be opened, and the tap water can enter the flushing port 12 through the water inlet valve 32 and the control valve 50 to clean the roller brush or mop, or the cleaning tank of the cleaning equipment; after the roller brush, mop or cleaning tank is cleaned, the control valve 50 controls the passage between the water inlet pipe 31 and the pump body unit 21 to be opened, so as to inject water into the internal cavity of the pump body unit 21 before the pump body unit 21 is started; after the internal cavity of the pump body unit 21 is filled with water, the pump body unit 21 is started. Since the internal cavity of the pump body unit 21 is pre-filled with water, the pump body unit 21 will discharge water after starting to generate negative pressure, and the sewage will be sucked into the pump body unit 21 through the sewage suction pipe 22, and then discharged into the sewer through the sewage discharge pipe 23.

[0063] In this embodiment, the volume of the internal cavity of the pump body unit 21 is larger than the total volume of the internal channel of the sewage suction pipe 22, so that air can be prevented from entering the pump body unit 21 and causing a negative pressure to fail to be generated.

[0064] In another embodiment of the present disclosure, Figure 2 As shown, the water supply assembly 30 is configured to be connected to a water storage chamber 25 through a water diversion pipe 24, and the water storage chamber 25 is configured to be connected to the internal cavity of the pump body unit 21, so that the water supply assembly 30 is connected to the pump body unit 21 through the water storage chamber 25; the water supply assembly 30 may include a clean water tank 33, and the water supply assembly 30 is configured to supply water to the water diversion pipe 24 through the clean water tank 33. The water supply assembly 30 also includes a water inlet pipe 31 and a clean water pump 34, the water inlet pipe 31 is configured to be connected between the clean water tank 33 and the water diversion pipe 24, and the clean water pump 34 is configured to be connected to the water inlet pipe 31.

[0065] In the above scheme, when the water supply component 30 supplies water to the pump body unit 21 through the clean water tank 33, in order to ensure that the cavity of the pump body unit 21 is filled with water before the pump body unit 21 is started, a water storage chamber 25 can be set between the pump body unit 21 and the water supply component 30. The function of the water storage chamber 25 is to store more clean water for the pump body unit 21 in advance to prevent the pump body unit 21 from being unable to be filled with water due to insufficient water in the clean water tank 33.

[0066] In one embodiment of the present disclosure, Figure 2 As shown, the pump body unit 21 further includes a liquid level detection component 26 , which is disposed on the water storage chamber 25 , and is configured to detect whether the liquid in the water storage chamber 25 reaches a preset liquid level line.

[0067] By setting the liquid level detection member 26, it is possible to detect whether the liquid in the water storage chamber 25 has reached a preset liquid level line. When the amount of water in the water storage chamber 25 has not reached the preset liquid level line, the passage between the pump unit 21 and the water supply assembly 30 can be opened by the control valve 50 to supply water to the water storage chamber 25. The preset liquid level line can indicate whether the internal chamber of the pump unit 21 has been filled with water or can be filled with water before the pump unit 21 is started, thereby further preventing the occurrence of a situation in which the internal chamber is not filled with water when the pump unit 21 is started. For example, the preset liquid level line can be a full water level line of the water storage chamber 25.

[0068] In one embodiment of the present disclosure, Figure 2 As shown, the liquid level detection member 26 includes two electrodes 261 inserted on the top of the water storage chamber 25. The two electrodes 261 are configured to be conductive when the liquid in the water storage chamber 25 reaches a preset liquid level line; the liquid level detection member 26 is configured to generate a prompt signal to the user that the current liquid level has not reached the preset liquid level line when the two electrodes 261 are disconnected. In this way, the structure of the liquid level detection member 26 is simple, and the liquid level line is detected by whether the two electrodes 261 are conductive by liquid.

[0069] Specifically, a detection circuit can be set at the top of the two electrodes 261, the two electrodes 261 are set at the top of the water storage chamber 25, and the bottom ends of the two electrodes 261 can be on a preset liquid level line and separated from each other, so that the above-mentioned detection circuit is open-circuited. In this way, when the water in the water storage chamber 25 reaches the preset liquid level line, the bottom ends of the two electrodes 261 can touch the water to form a passage, and the above-mentioned detection circuit can generate a corresponding electrical signal.

[0070] It is understandable that the specific structure of the liquid level detection component is not limited thereto.

[0071] Specifically, the working process of the base station provided in one embodiment of the present disclosure may be as follows: Figure 2 As shown, the water inlet pipe 31 is directly connected to the clean water tank 33, and the control valve 50 controls the passage between the water inlet pipe 31 and the flushing port 12 to be opened. At this time, the passage between the water inlet pipe 31 and the pump body unit 21 is closed, and the clean water pump 34 can transport the water in the clean water tank 33 to the flushing port 12 to clean the roller brush, mop or cleaning tank of the cleaning equipment; after the roller brush, mop or cleaning tank is cleaned, when the liquid level detection component detects that the water amount in the water storage chamber 25 is insufficient (has not reached the preset liquid level line), the control valve 50 controls the passage between the water inlet pipe 31 and the pump body unit 21 to be opened, At this time, the passage between the water inlet pipe 31 and the flushing port 12 is closed, and the clean water pump 34 can transport the water in the clean water tank 33 to the water storage chamber 25 until the liquid level detection component detects that the water level in the water storage tank reaches the preset liquid level line, indicating that the internal cavity of the pump body unit 21 is filled with water; after the internal cavity of the pump body unit 21 is filled with water, when necessary, the pump body unit 21 is started. Since the internal cavity of the pump body unit 21 is pre-filled with water, the pump body unit 21 will discharge water to generate negative pressure after starting, and the sewage will be sucked into the pump body unit 21 through the sewage suction pipe 22, and then discharged into the sewer through the sewage discharge pipe 23.

[0072] In this embodiment, at least part of the pipeline of either the suction pipe 22 or the discharge pipe 23 is constructed to be located higher than the preset liquid level line of the water storage chamber 25. As shown in the figure, the highest position of the suction pipe 22 and the discharge pipe 23 is b, and the preset liquid level line in the water storage chamber 25 is higher than position b. In this way, it is possible to prevent the water in the water storage chamber 25 from flowing away from the suction pipe 22 or the discharge pipe 23 due to its own gravity or siphon effect.

[0073] In this embodiment, the sum of the volumes of the water storage chamber 25 and the internal cavity of the pump unit 21 is greater than the total volume of the internal channel of the sewage suction pipe 22, which can prevent air from entering the pump unit 21 and causing a failure to generate negative pressure.

[0074] It should be noted that in Figure 1In the illustrated embodiment, when the water supply assembly 30 is configured to be connected to tap water, the pump unit 21 is configured to be directly connected to the water supply assembly 30 through a water supply pipe 24; Figure 2 In the illustrated embodiment, when the water supply assembly 30 is configured to be supplied with water by the clean water tank 33 , the pump unit 21 is configured to be connected to the water supply assembly 30 through the water storage chamber 25 and the water guide pipe 24 .

[0075] It should be understood that in other embodiments, when the water supply assembly 30 is constructed to be connected to tap water, the pump body unit 21 can also be constructed to be connected to the water supply assembly 30 through the water storage chamber 25 and the water diversion pipe 24; or, when the water supply assembly 30 is constructed to be supplied with water by the clean water tank 33, the pump body unit 21 can also be constructed to be directly connected to the water supply assembly 30 through a water diversion pipe 24.

[0076] like Figure 1 and Figure 2 As shown, the embodiment of the present disclosure further provides a base station, including:

[0077] A base 10, on which a sewage outlet 11 is provided;

[0078] The sewage discharge assembly 20 is disposed on the base 10 and includes a pump unit 21, a sewage suction pipe 22 and a sewage discharge pipe 23. The liquid inlet side of the pump unit 21 is configured to be connected to the sewage outlet 11 through the sewage suction pipe 22, and the liquid discharge side of the pump unit 21 is connected to the sewage discharge pipe 23;

[0079] The pump unit 21 has an internal cavity, and is configured to start and generate negative pressure when liquid is stored in the internal cavity, so as to pump out sewage flowing into the sewage outlet 11 .

[0080] In one embodiment of the present disclosure, the base station also includes a water supply component 30, which is configured to supply water to the internal cavity of the water pump unit 21. The water pump unit 21 is configured to start and generate negative pressure after the water supply component 30 is filled with water to pump out the sewage flowing into the sewage outlet 11.

[0081] In the above scheme, the sewage discharge component 20 on the base station includes a pump body unit 21, a sewage suction pipe 22 and a sewage discharge pipe 23. The water supply component 30 on the base station can supply water to the internal cavity of the pump body unit 21, so that before the pump body unit 21 is started, the internal cavity of the pump body unit 21 is first filled with water through the water supply component 30, so that the internal cavity of the pump body unit 21 can generate negative pressure when the pump body unit 21 is started, thereby sucking the sewage into the pump body unit 21 through the sewage suction pipe 22, and then discharging the sewage from the sewage discharge pipe 23 through the pump body unit 21.

[0082] In this way, before the pump body unit 21 is started, water is supplied to the internal cavity of the pump body unit 21 through the water supply assembly 30, so that the internal cavity of the pump body unit 21 is filled with water, so that the pump body unit 21 has self-priming ability, so that when the pump body unit 21 is started, its internal cavity can generate negative pressure to smoothly pump out the sewage. Compared with the solution of using an air pump and a sewage tank to discharge sewage on the base station in the related technology, there is no need to set up a sewage pump and an air pump, which can simplify the base station structure and reduce the size of the base station.

[0083] Application scenario 1

[0084] This application scenario provides a cleaning system, which includes a cleaning device and a base station. Figure 1 and Figure 2 As shown, the base station includes a base 10, a sewage discharge assembly 20 and a water supply assembly 30. The base 10 is provided with a sewage discharge port 11; the sewage discharge assembly 20 is arranged on the base 10, and the sewage discharge assembly 20 includes a pump unit 21, a sewage suction pipe 22 and a sewage discharge pipe 23. The liquid inlet side of the pump unit 21 is configured to be connected to the sewage discharge port 11 through the sewage suction pipe 22, and the liquid discharge side of the pump unit 21 is connected to the sewage discharge pipe 23; the water supply assembly 30 is configured to supply water to the internal cavity of the pump unit 21, and the pump unit 21 is configured to start and generate negative pressure after the water supply assembly 30 is filled with water, so as to pump out the sewage flowing into the sewage discharge port 11.

[0085] The cleaning system provided by the embodiment of the present disclosure includes a cleaning device and a base station. The base station includes a base 10, a sewage discharge component 20 and a water supply component 30. The sewage discharge component 20 includes a pump body unit 21, a sewage suction pipe 22 and a sewage discharge pipe 23. The water supply component 30 can supply water to the internal cavity of the pump body unit 21, so that before the pump body unit 21 is started, the internal cavity of the pump body unit 21 is first filled with water through the water supply component 30, so that the internal cavity of the pump body unit 21 can generate negative pressure when the pump body unit 21 is started, thereby sucking sewage into the pump body unit 21 through the sewage suction pipe 22, and then discharging the sewage from the sewage discharge pipe 23 through the pump body unit 21.

[0086] After the cleaning equipment completes self-cleaning, before the pump unit 21 is started, water is supplied to the internal cavity of the pump unit 21 through the water supply assembly 30 to fill the internal cavity of the pump unit 21 with water; when the internal cavity of the pump unit 21 is filled with water, the pump unit 21 is started, and a negative pressure can be generated in the internal cavity of the pump unit 21. The sewage at the sewage outlet 11 is sucked by the pump unit 21 through the sewage suction pipe 22 under the action of the negative pressure, and then discharged through the sewage pipe 23.

[0087] Application scenario 2

[0088] A base station is provided in this application scenario. In one embodiment of the present disclosure, the base station includes a base 10, a sewage discharge component 20, and a water supply component 30. A sewage trough can be provided on the base 10, and the sewage trough can be used to place cleaning elements such as a roller brush or a rag of a cleaning device to perform self-cleaning on the roller brush or the rag of the cleaning device.

[0089] A sewage outlet 11 is connected to the sewage tank, and the sewage outlet 11 is used to discharge the sewage in the sewage tank. When the cleaning equipment performs self-cleaning, the cleaned sewage will flow into the sewage tank. When it is necessary to discharge the sewage in the sewage tank, the water supply component 30 on the base station can supply water to the internal cavity of the pump body unit 21, so that before the pump body unit 21 is started, the internal cavity of the pump body unit 21 is first filled with water through the water supply component 30, so that the internal cavity of the pump body unit 21 can generate negative pressure when the pump body unit 21 is started, thereby sucking the sewage into the pump body unit 21 through the sewage outlet 11, and then discharging the sewage from the sewage pipe 23 through the pump body unit 21. With such a structural design, it is no longer possible to set up water storage components such as sewage tanks, and there is no need to use traditional negative pressure units such as fan components. This can greatly reduce the volume of the base station, which is conducive to the optimal layout of the base station.

[0090] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the marketplace, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
