[0064] For ease of understanding, refer to Figures 1 to 16 , the specific structure and working principle of the cleaning robot system and base station disclosed in the present invention are explained in detail in combination with an embodiment.

The negative pressure generating unit 122 is constructed to have an exhaust end 122A and an exhaust end 122B. The exhaust end 122A can exhaust air to generate negative pressure, and the exhaust end 122B can blow air to generate positive pressure. The air suction end 122A is constructed to be connected to the sewage tank 121 through the air inlet pipe 121' to form a negative pressure in the sewage tank 121; the air exhaust end 122B is constructed to be connected to the flushing port 11A, and the positive-pressure gas delivered by the air exhaust end 122B flows out from the flushing port 11A, or the positive-pressure gas delivered by the air exhaust end 122B is mixed with the water delivered by the water supply component to form a gas-liquid mixture greater than the water supply pressure of the water supply component, and then flows out from the flushing port 11A.

[0068] In this way, when the mop and roller brush of the cleaning robot are placed in the cleaning tank, the negative pressure generating unit 122 is started, and the exhaust end 122A exhausts air, which can form a negative pressure in the sewage tank 121, so that the dirt is sucked into the sewage tank 121; and the positive pressure gas blown by the exhaust end 122B can be delivered to the flushing port 11A, so that the cleaning robot can be directly cleaned with the positive pressure gas, or the positive pressure gas and the water delivered to the flushing port 11A by the water supply component can be used to form a gas-liquid mixture with a pressure greater than the water supply pressure of the water supply component, and then flow out from the flushing port 11A to clean the mop and roller brush of the cleaning robot, and / or the cleaning tank, thereby realizing the self-cleaning function of the cleaning robot.

[0070] It should be noted that in the prior art, a vacuum air pump or the like is usually provided on the base station 10 of the cleaning robot system to generate negative pressure to suck out sewage. In the cleaning robot system provided in the embodiment of the present disclosure, a vacuum air pump or the like is directly utilized, which can not only utilize the negative pressure generated by its suction end 122A to suck out dirt, but also utilize the positive pressure generated by its exhaust end 122B to provide flushing pressure.

[0071] In one embodiment of the present disclosure, Figure 2 and Figure 3 As shown, a cleaning tank 111 is provided on the base 11, and the cleaning tank 111 includes a flushing area S1 and a sewage area S2.

Specifically, the cleaning tank 111 can be configured to have a slope, and the height of the flushing area S1 is higher than the height of the sewage area S2. The sewage tank 121 can be configured to be connected to the sewage outlet 11B through the sewage pipe 120.

[0074] In one embodiment of the present disclosure, the base 11 may also be provided with a sewage docking port for docking with the cleaning robot, and the sewage docking port may be connected to the sewage tank 121 through a sewage pipe 120.

[0078] According to different types of dirt, appropriate methods such as air blowing, water flushing or water-gas mixture flushing can be selected to clean the roller brush or mop and / or clean the cleaning tank. For example, the roller brush and mop can be cleaned by water flushing, and the generated sewage is sucked into the sewage tank 121, while solid garbage such as hair, particles, dust, etc. may remain in the cleaning tank 111. At this time, the solid garbage can be blown to the sewage outlet 11B by combining air blowing or water-gas mixture flushing, so as to clean the dirt in time and avoid the accumulation of dirt in the cleaning tank 111.

[0079] In one embodiment of the present disclosure, please combine Figure 4 and Figure 5As shown, the water supply component also includes a first power pump 142 and a first water supply pipeline 143.

The first power pump 142 may be any suitable component such as a diaphragm pump.

[0080] In the above scheme, the first power pump 142 can pressurize the water in the clean water tank 141 to form high-pressure water and deliver it to the first water supply pipeline 143; the negative pressure generating unit 122 can deliver the positive pressure gas to the first exhaust pipeline 123, see Figure 4 As shown, the first exhaust pipeline 123, the first water supply pipeline 143 and the first flushing pipeline 15 can be connected to each other through the tee 16. In this way, one or both of the high-pressure water in the first exhaust pipeline 123 and the positive-pressure gas in the first exhaust pipeline 123 can be transported to the flushing port 11A through the first flushing pipeline 15.

[0081] In this embodiment, if Figure 6 As shown, the base 11 is also provided with a water replenishment port 11C, which is used to replenish water for the cleaning robot.

[0082] In the above scheme, by controlling the opening and closing state of the first control valve 145, the water in the clean water tank 141 can be delivered not only to the flushing port 11A to deliver high-pressure water, but also to the water replenishment port 11C. In other words, the first power pump 142, the clean water tank 141 and the first control valve 145 in the water supply assembly for supplying water to the flushing port 11A are reused as the water supply assembly of the water replenishment port 11C. In this way, the structure is more compact and the cost is lower. Of course, it can be understood that in other embodiments, a power pump and a control valve connected to the clean water tank 141 can also be separately provided to deliver water to the water replenishment port 11C.

[0084] In the above scheme, when the cleaning robot system needs to self-clean, the control unit sends a control instruction to control the working state of the water supply component and the sewage discharge component 12 to realize the pulse flushing method. Specifically, the self-cleaning process of the cleaning robot system can be as follows: in a pulse cycle, in the first time period, the control unit sends a first control instruction to the water supply component and the sewage discharge component 12, the first power pump 142 is started (the first water outlet end of the control valve is opened), and the negative pressure generating unit 122 is closed. At this time, the first water supply pipeline 143 delivers positive pressure water, and the exhaust pipeline is cut off, and at least part of the positive pressure water fills the flushing pipeline; in the second time period, the control unit sends a second control instruction to the water supply component and the sewage discharge component 12, controls the first power pump to be closed, and the negative pressure generating unit 122 is started, so that the exhaust pipeline delivers positive pressure gas, and the first water supply pipeline 143 is cut off. At this time, the positive pressure of the positive pressure gas is used to spray the water in the flushing pipeline, and the negative pressure of the negative pressure generating unit 122 is used to suck the dirt into the sewage tank 121. Repeatedly, the pulse flushing process is realized to improve the cleaning effect.

[0085] In another embodiment of the present disclosure, the base station 10 also includes: a control unit, which is electrically connected to the water supply component and the sewage discharge component 12, and the control unit is configured to send a third control instruction to the water supply component and the sewage discharge component 12 within a predetermined time period, so that the first water supply pipeline 143 and the first exhaust pipeline 123 are simultaneously opened, and the positive pressure water and the positive pressure gas are simultaneously delivered to the first flushing pipeline 15 for mixing.

[0086] In the above scheme, when the cleaning robot system needs to self-clean, the control unit sends a control instruction to control the working state of the water supply component and the sewage discharge component 12 to realize the high-pressure gas-liquid mixture flushing method. Specifically, the self-cleaning process of the cleaning robot system can be as follows: the control unit sends a third control instruction, the negative pressure generating unit 122 and the first power pump 142 are started at the same time, the first power pump 142 draws water from the clean water tank 141 and delivers it to the first liquid supply pipeline, and at the same time the negative pressure generating unit 122 delivers the positive pressure gas to the exhaust pipeline. Since the exhaust pipeline is connected in parallel with the first liquid supply pipeline and is connected to the flushing pipeline through the three-way piece 16. Therefore, the positive pressure gas and high-pressure water will mix at the position of the three-way piece 16 to form a high-pressure gas-liquid mixture (water mist), and the high-pressure gas-liquid high-pressure gas-liquid mixture will then reach the flushing port 11A through the flushing pipe. The hair, floating dust, oil and other dirt remaining in the cleaning tank 111 can be blown to the drain port 11B of the cleaning tank 111 under the pressure of the high-pressure gas-liquid mixture, and be sucked out and emptied under the negative pressure, thereby realizing the self-cleaning function of the cleaning robot system. This method of high-pressure flushing using a high-pressure gas-liquid mixture can be applied to flushing roller brushes, mops and the cleaning tank 111, which can improve the cleaning effect.

[0087] In one embodiment of the present disclosure, filters may be installed at the water inlet end of the first power pump 142 and the air inlet end of the negative pressure generating unit 122 to prevent foreign matter from entering the system and causing blockage of the pipeline or components in the pipeline.

[0088] In one embodiment of the present disclosure, the first water supply pipeline 143, the first exhaust pipeline 123 and the first flushing pipeline 15 are connected to each other through a three-way piece 16, and the three-way piece 16 can be a three-way joint or an ejector. The ejector is also called a water ejector, a venturi tube, etc., which can mix gas with liquid, or liquid with liquid to form a high-pressure water-gas mixture (i.e., high-pressure water mist). When the first water supply pipeline 143, the exhaust pipeline and the flushing pipeline are connected to each other through the ejector, the ejector can include a gas inlet end, a liquid inlet end and an outlet end, the first exhaust pipeline 123 is connected to the gas inlet end, the first water supply pipeline 143 is connected to the liquid inlet end, and the first flushing pipeline 15 is connected to the outlet end.

[0089] In one embodiment of the present disclosure, the working flow rate (liquid flow rate) of the first power pump 142 may be 0.3L to 3L / min, and the working flow rate (gas flow rate) of the negative pressure generating unit 122 may be 1 to 30L / min.

[0090] It should be noted that, in order to achieve an ideal flushing effect, if the gas flow rate is large, the water consumption can be small; if the gas flow rate is small, the water flow rate needs to be increased accordingly. In an exemplary embodiment, the water flow rate can be 0.5L / min and the gas flow rate can be 30L / min.

[0091] In another embodiment of the present disclosure, Figure 6 and Figure 7 As shown, the exhaust end 122B is constructed to be connected to the second exhaust pipeline 124, the flushing port 11A is constructed to be connected to the second flushing pipeline 17, and the water outlet end of the clean water tank 141 is constructed to be connected to the third water supply pipeline 146; wherein the third water supply pipeline 146 is constructed to be connected to the second flushing pipeline 17 in parallel with the second exhaust pipeline 124, so that the water in the clean water tank 141 is sucked into the second flushing pipeline 17 under the action of siphon.

[0092] In the above scheme, the third water supply pipeline 146 and the second exhaust pipeline 124 are connected in parallel to the second flushing pipeline 17, so that the water outlet of the clean water tank 141 is directly siphoned into the third water supply pipeline 146 under the action of the positive pressure gas transported in the second exhaust pipeline 124, and mixed with the positive pressure gas to form a high-pressure gas-liquid mixture, and transported to the flushing port 11A through the second flushing pipeline 17. In this way, due to the siphon effect, liquid molecules of 5-10 μm can be generated. Compared with the embodiment shown in the above figure, the amount of water used for flushing can be smaller, and the space of the base station 10 and the frequency of water addition are saved, and the flushing effect of common stains such as floating dust and animal hair is better.

[0093] In this embodiment, please combine Figures 6 to 8 The base station 10 also includes: an ejector 18, which is constructed to mix water vapor to form water mist. The ejector 18 includes a gas inlet port 18A, a liquid inlet port 18B and an outlet port 18C. The second exhaust pipeline 124 is connected to the gas inlet port 18A, the third water supply pipeline 146 is connected to the liquid inlet port 18B, and the second flushing pipeline 17 is connected to the outlet port 18C.

[0094] In the above scheme, the negative pressure generated by the high-speed flowing gas is used to siphon the water in the clean water tank 141, and the ejector 18 can be used to mix the water and the gas to form a high-pressure water mist to achieve flushing. In this embodiment, the base station 10 also includes a control unit, which is connected to the negative pressure generating unit 122, and the control unit is configured to control the working state of the negative pressure generating unit 122 to achieve self-cleaning.

[0095] In the above scheme, when the cleaning robot system needs to self-clean, the control unit sends a control instruction to control the working state of the sewage discharge component 12 to achieve a high-pressure gas-liquid mixture flushing method.

[0096] Specifically, the self-cleaning process of the cleaning robot system can be as follows:

[0097] When the cleaning system needs to self-clean, the control unit sends a control instruction to control the negative pressure generating unit 122 to start. At this time, the air suction end 122A sucks air to form a negative pressure in the sewage tank 121 to suck the dirt from the sewage outlet 11B. The exhaust end 122B delivers the sucked air to the ejector 18. The air flow in the ejector 18 changes drastically to generate negative pressure, thereby siphoning the water in the clean water tank 141, so that the water vapor merges to form a high-pressure water mist, which is delivered to the flushing port 11A through the second flushing pipeline 17. The hair, floating dust, etc. remaining in the cleaning tank 111 can be blown to the sewage outlet 11B under the action of the water mist pressure, and sucked into the sewage tank 121 through the sewage outlet 11B, thereby realizing the self-cleaning function. In this embodiment, filters can be installed at the third water supply pipeline 146 and the air suction end 122A of the negative pressure generating unit 122 to prevent foreign matter from entering the pipeline and the components in the pipeline and causing blockage.

[0099] In the above scheme, the clean water tank 141 can not only provide water for flushing, but also supply water for the cleaning robot. In other words, the clean water tank 141 for supplying water to the cleaning robot is directly used as the clean water tank 141 for flushing, and the structure can be more compact.

[0100] In one embodiment of the present disclosure, a check valve for controlling the flow direction of gas is provided on the exhaust pipe between the exhaust port 122B and the flushing port 11A. Figure 4 and Figure 5 As shown, a check valve 19 is provided on the first exhaust line 123 .

The third exhaust pipeline 125 and the water supply pipeline in the water supply assembly are independent of each other. In this way, a separate air blowing flushing method or a separate water supply flushing method can be selected for self-cleaning in combination with the type of dirt in the actual application scenario.

[0114] It should be noted that the fifth water supply pipeline 140 can also be configured to be connected to the flushing port 11A and be independent of the third exhaust pipeline 125, or can be configured to be disconnected from the flushing port 11A. The water supply assembly can include a clean water tank 141, a third power pump 151, and a third control valve 152, which are sequentially arranged on the fifth water supply pipeline 140 along the water delivery direction.
