[0056] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0057] Unless otherwise stated, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of the various embodiments / examples may be further combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.

[0058] The use of cross hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise indicated, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the order described. In addition, the same figure numbers represent the same components.

[0059] When a component is referred to as being “on,” “over,” “connected to,” or “coupled to” another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another component, there are no intervening components present. For this purpose, the term “connected” may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0060] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "under," "down," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings.

It should also be noted that, as used herein, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

[0062] Figure 1 It is a structural schematic diagram of a floor cleaning device according to one embodiment of the present disclosure. Figure 2 It is a schematic diagram of the pipeline connection relationship of the floor cleaning equipment according to one embodiment of the present disclosure.

[0063] like Figure 1 and Figure 2 As shown, the present disclosure provides a floor cleaning device, which can be formed in the form of a mobile cleaning robot.

[0064] In one example, the floor cleaning device may have a rotatable brush to disturb the solid waste on the surface to be cleaned. At this time, the suction component on the floor cleaning device is actuated to generate negative pressure; the negative pressure is applied to the dust collecting component (also called a dust box), so that the solid waste and gas can be sucked into the interior of the dust collecting component, and the interior of the dust collecting component performs gas-solid separation, and the solid waste is stored in the dust collecting component, and the separated clean gas is discharged to the outside of the floor cleaning device, thereby completing the sweeping operation of the floor cleaning device.

[0065] The floor cleaning device also has a wet mopping function. Accordingly, the floor cleaning device includes a cleaning liquid storage section 110, which stores cleaning liquid. When wet mopping the surface to be cleaned, the cleaning liquid in the cleaning liquid storage section 110 can be provided to the surface to be cleaned, or provided to the cleaning section 120 of the floor cleaning device. When the mop rotates (for example, rotates around an axis perpendicular to the surface to be cleaned), the wet mopping operation of the surface to be cleaned is completed.

[0066] In a preferred embodiment, the cleaning portion 120 may be formed as a circular mop or a mop in other shapes. When the mop is in frictional contact with the surface to be cleaned, a wet mopping operation can be performed on the surface to be cleaned.

[0067] The cleaning liquid storage portion 110 is formed in the form of a water tank and can be used to store cleaning liquid. In one embodiment, the cleaning liquid storage portion 110 can be formed in a sealed form. For example, the cleaning liquid storage portion 110 can include a box body and a cover body. A sealing ring or other structure can be provided between the box body and the cover body, so that the cleaning liquid storage portion 110 itself is formed in a sealed form.

[0068] The floor cleaning device 100 further includes a first pump 130 and a second pump 140 . The first pump 130 is connected to the cleaning liquid storage portion 110 for supplying cleaning liquid to the cleaning portion 120 . The cleaning portion 120 can clean the floor based on the cleaning liquid provided by the first pump 130 or perform self-cleaning on the cleaning portion 120 .

[0069] Those skilled in the art will appreciate that the first pump 130 can be a liquid pump, such as a peristaltic pump or a plunger pump, and is preferably a peristaltic pump. In particular, when the first pump 130 is a peristaltic pump, the water supply line can be promptly closed when the peristaltic pump stops supplying water. Furthermore, given that the peristaltic pump can be turned over, any remaining cleaning liquid in the water supply line can be pumped back into the cleaning liquid storage unit 110.

[0070] Positionally, the first pump 130 is located adjacent to the cleaning liquid storage unit 110 and is connected to the cleaning liquid storage unit 110 via a water pipe. Furthermore, a discharge pipe 131 is connected to the outlet of the first pump 130. The number of discharge pipes 131 can be determined based on the number of cleaning units 120. In one embodiment, when there are two cleaning units 120, there are also two discharge pipes 131. In this case, the discharge pipes 131 are provided in a one-to-one correspondence with each cleaning unit 120.

[0071] The second pump 140 is used to provide cleaning liquid into the cleaning liquid storage portion 110 . Specifically, the second pump 140 can pump the cleaning liquid in the cleaning liquid supply portion 210 of the base station 200 into the cleaning liquid storage portion 110 .

[0072] In one embodiment, the second pump 140 is selected as a pneumatic pump, which can generate negative pressure when working. The negative pressure can be applied to the cleaning liquid storage part 110, thereby sucking the cleaning liquid in the cleaning liquid supply part 210 of the base station 200 into the floor cleaning equipment.

[0073] Positionally, the second pump 140 is disposed adjacent to the cleaning liquid storage portion 110. In a preferred embodiment, the second pump 140 is located directly below the cleaning liquid storage portion 110. Furthermore, the second pump 140 is connected to the cleaning liquid storage portion 110 via a pipe. Accordingly, the pipe has a certain strength, thereby preventing significant deformation of the pipe when the second pump 140 is operating.

[0074] In the present disclosure, the floor cleaning device 100 also includes a water replenishment interface 150, which can be located at the side wall of the floor cleaning device 100 and can be connected to the supply interface 230 of the base station 200; in a preferred embodiment, the supply interface 230 of the base station 200 can be formed as a protruding structure, and when the water replenishment interface 150 is connected to the supply interface 230, the supply interface 230 can be inserted into the interior of the water replenishment interface 150, thereby forming a sealed connection between the supply interface 230 and the water replenishment interface 150.

[0075] The water replenishment interface 150 is in communication with the cleaning liquid storage unit 110 so that cleaning liquid or gas can be supplied to the cleaning liquid storage unit 110 through the water replenishment interface 150. Specifically, when the floor cleaning device 100 is docked with the base station 200 and connected to the base station 200, the floor cleaning device is in fluid communication with the base station 200. At this time, cleaning liquid can be supplied to the cleaning liquid storage unit 110 through the water replenishment interface 150. On the other hand, when the floor cleaning device 100 leaves the base station 200 and is in operation, since the first pump 130 can continuously pump out cleaning liquid, gas can enter the interior of the cleaning liquid storage unit 110 through the water replenishment interface 150, thereby balancing the internal and external air pressures of the cleaning liquid storage unit 110.

[0076] In the present disclosure, when the ground cleaning device is docked with the base station 200 and is fluidically connected through the water replenishment interface, the cleaning liquid storage part 110 is in a sealed state. When the second pump 140 applies negative pressure to the cleaning liquid storage part 110, the cleaning liquid in the base station 200 is sucked into the cleaning liquid storage part 110.

[0077] Therefore, the base station 200 does not need to include a water supply pump or a pneumatic pump, thereby reducing the number of pumps in the entire floor cleaning system, lowering the cost, and increasing the service life of the floor cleaning system.

[0078] Furthermore, when the first pump 130 pumps the cleaning liquid in the cleaning liquid storage part for self-cleaning of the cleaning part, the negative pressure generated by the first pump 130 pumping the cleaning liquid pumps the cleaning liquid in the base station into the cleaning liquid storage part.

[0079] Figure 3 Schematic diagram of the structure of a one-way valve according to one embodiment of the present disclosure.

[0080] In one embodiment, Figure 3 As shown, a one-way valve 160 is provided on the connecting pipeline between the second pump 140 and the cleaning liquid. The one-way valve 160 allows gas and / or liquid to flow from the cleaning liquid storage part 110 to the second pump 140, and accordingly, does not allow gas and / or liquid to flow from the second pump 140 to the cleaning liquid storage part 110.

[0081] Therefore, when the cleaning liquid storage part 110 of the floor cleaning device 100 is in the water replenishment process, when the second pump 140 starts to pump air, pressure will be generated in the connecting pipeline. At this time, the one-way valve 160 opens, and the gas in the cleaning liquid storage part 110 is pumped out of the paper cleaning liquid storage part 110 through the one-way valve 160, thereby forming a negative pressure inside the cleaning liquid storage part 110, thereby achieving the replenishment of the cleaning liquid.

[0082] On the other hand, when the floor cleaning device is in a non-working state and tilted, for example, when the floor cleaning device 100 is lifted and tilted, when there is no pressure inside the cleaning liquid storage part 110 to supply the one-way valve 160, the one-way valve 160 remains closed, thereby preventing the cleaning liquid in the cleaning liquid storage part 110 from leaking out through the connecting pipe.

[0083] Figure 4 and Figure 5 It is a structural schematic diagram of a drain outlet according to an embodiment of the present disclosure.

[0084] like Figure 4 and Figure 5 As shown, when the cleaning liquid in the cleaning liquid storage portion 110 enters the second pump 140 , the cleaning liquid is discharged from the drain port 141 of the second pump 140 .

[0085] For example, if the full water detection function of the cleaning liquid storage unit 110 fails, the overflowing water in the cleaning liquid storage unit 110 is pumped out by the second pump 140, thereby preventing the water tank from overflowing. Preferably, the drainage outlet of the second pump 140 can be discharged to the bottom of the floor cleaning device 100 through a drainage pipe. At this time, since the cleaning liquid storage unit 110 is docked on the base station 200, the cleaning liquid can be discharged to the base of the base station 200, and further the cleaning liquid can flow into the groove of the base station 200, which is a component of the cleaning unit of the floor cleaning device.

[0086] Figure 6 It is a structural diagram of a base station according to an embodiment of the present disclosure. Figure 7 Schematic diagram of the connection relationship between a base station and a floor cleaning device according to an embodiment of the present disclosure.

[0087] According to another aspect of the present disclosure, Figure 6 and Figure 7 As shown, the present disclosure provides a floor cleaning system, which includes the above-mentioned floor cleaning equipment.

[0088] Moreover, the floor cleaning system also includes a base station 200, which can be used for docking the floor cleaning equipment and providing at least one of the following operations: charging the floor cleaning equipment, replenishing cleaning liquid, transferring solid waste in the floor cleaning equipment, and self-cleaning the cleaning part of the floor cleaning equipment.

[0089] The structure of the base station 200 is described below with reference to the accompanying drawings.

[0090] like Figure 6 and Figure 7As shown, in a typical embodiment, the base station 200 may include components such as a cleaning liquid supply unit 210 , a sewage tank 220 , and a supply interface 230 .

[0091] The cleaning liquid supply unit 210 may be formed in the form of a water tank, capable of storing the cleaning liquid and providing the stored cleaning liquid to the outside.

[0092] In one embodiment, the cleaning liquid supply unit 210 can be connected to a municipal water network, thereby enabling automatic replenishment of the cleaning liquid. Of course, those skilled in the art will appreciate that the cleaning liquid supply unit 210 can also be manually replenished by the user. In one embodiment, the volume of the cleaning liquid supply unit 210 is greater than the volume of the cleaning liquid storage unit 110. For example, the volume of the cleaning liquid supply unit 210 can be more than five times greater than the volume of the cleaning liquid storage unit 110.

[0093] The supply interface 230 is connected to the cleaning liquid supply unit 210 , so that the cleaning liquid stored in the cleaning liquid supply unit 210 can be provided to the floor cleaning device through the supply interface 230 .

[0094] For example, when the ground cleaning device is docked with the base station 200, the water replenishment interface is connected to the supply interface 230; more preferably, a water replenishment valve is provided on the connecting pipeline between the cleaning liquid supply part 210 and the supply interface 230. When the ground cleaning device 100 completes water replenishment or the self-cleaning of the cleaning part of the ground cleaning device 100 is completed, the water replenishment valve is closed.

[0095] In one embodiment, the water supply valve can be a mechanical valve or a solenoid valve, and is disposed adjacent to the supply interface 230 , thereby minimizing the amount of cleaning liquid leaked after the floor cleaning device and the main unit are separated.

[0096] In the present disclosure, when the cleaning liquid supply part 210 provides the cleaning liquid to the outside, the cleaning liquid in the cleaning liquid supply part 210 is transported to the floor cleaning equipment through the suction effect of the floor cleaning equipment.

[0097] At this time, the base station 200 does not include a pump capable of sucking the cleaning liquid, and does not include a pump for applying pressure to the cleaning liquid supply part 210; that is, the base station 200 does not include a pump device for conveying the cleaning liquid.

[0098] The base has a groove. When the floor cleaning device is docked at the base station, the cleaning part (mop) of the floor cleaning device is located above or inside the groove, and the cleaning part of the floor cleaning device is self-cleaned in the groove.

[0099] The sewage tank 220 is formed in the form of a water tank and can store sewage. In one embodiment, the sewage tank 220 is connected to the groove of the base via a sewage pump, and after the self-cleaning of the cleaning unit 120 is completed, the used cleaning liquid (sewage) can be sucked into the sewage tank by the sewage pump and temporarily stored in the sewage tank.

[0100] Accordingly, when the amount of sewage in the sewage tank is large, the sewage in the sewage tank can be automatically discharged to the sewer, or the user can manually discharge the sewage to the sewer.

[0101] Figure 8 is a flowchart of a control method of a floor cleaning system according to one embodiment of the present disclosure.

[0102] According to another aspect of the present disclosure, Figure 8 As shown, a control method for a floor cleaning system is provided, which includes: when the floor cleaning device needs to self-clean, controlling the floor cleaning device to dock at the base station 200, and making the floor cleaning device fluidically connected to the base station 200; judging the amount of liquid in the cleaning liquid storage part 110 of the floor cleaning device, and when the amount of liquid in the cleaning liquid storage part 110 is greater than or equal to a preset value, performing self-cleaning of the cleaning part 120 of the floor cleaning device at least once; and after the self-cleaning of the cleaning part 120 of the floor cleaning device is completed, controlling the cleaning part 120 of the floor cleaning device to rotate to at least partially remove moisture in the cleaning part 120; and drying the cleaning part 120 of the floor cleaning device through a drying module.

[0103] In the present disclosure, the floor cleaning device 100 can automatically determine whether to perform self-cleaning on its cleaning unit. For example, when the floor cleaning device 100 is set to operate for a predetermined time, i.e., to perform self-cleaning on the cleaning unit, when the operating time reaches a preset value, it can autonomously perform self-cleaning on the cleaning unit.

[0104] On the other hand, the cleaning unit can be self-cleaned based on the cleanliness of the surface to be cleaned after the floor cleaning device cleans the surface to be cleaned. For example, when the dirtiness of the surface to be cleaned after cleaning is greater than a preset threshold (which can be determined by a camera), the cleaning unit is self-cleaned.

[0105] Moreover, after the floor cleaning device completes the cleaning operation, the cleaning portion of the floor cleaning device needs to be self-cleaned, which can prevent the dirt on the cleaning portion from emitting odor.

[0106] Of course, the self-cleaning of the cleaning part of the floor cleaning device can also be triggered by the user triggering the self-cleaning button of the floor cleaning device and / or the base station, or by a virtual button of a mobile phone APP or the like.

[0107] Then, the amount of liquid in the cleaning liquid storage part 110 of the floor cleaning device is determined. When the amount of liquid in the cleaning liquid storage part 110 is greater than or equal to a preset value, the self-cleaning of the cleaning part 120 of the floor cleaning device is performed at least once.

[0108] In the present disclosure, considering that the cleaning part 120 of the floor cleaning equipment has been working for a period of time during self-cleaning, its cleaning liquid storage part 110 is not in a full water state, therefore, the second pump 140 can be directly started to replenish water, and when the amount of cleaning liquid in the cleaning liquid storage part 110 is greater than or equal to a preset value, for example, when the cleaning liquid storage part 110 is full of water, the second pump 140 is stopped and the water replenishment process ends.

[0109] Accordingly, when the amount of liquid in the cleaning liquid storage portion 110 is greater than or equal to a preset value, self-cleaning of the cleaning portion 120 of the floor cleaning apparatus is performed at least once.

[0110] In the present disclosure, the number of self-cleaning operations of the cleaning unit 120 can be determined based on the degree of dirtiness of the cleaning unit 120. Accordingly, when the cleaning unit 120 is cleaned, the self-cleaning of the cleaning unit 120 is stopped.

[0111] Preferably, performing self-cleaning of the cleaning section 120 of the floor cleaning equipment at least once includes: starting the first pump 130 to supply cleaning liquid to the cleaning section 120 of the floor cleaning equipment; controlling the cleaning section 120 of the floor cleaning equipment to rotate and clean the cleaning section 120; and sucking the cleaning liquid after cleaning the cleaning section 120 of the floor cleaning equipment into the sewage tank 220 of the base station 200.

[0112] In the present disclosure, when the cleaning section 120 performs self-cleaning, the cleaning liquid provided to the cleaning section 120 can be stored in the groove of the base. Accordingly, when the amount of cleaning liquid in the groove is greater than or equal to a preset value, the supply of cleaning liquid is stopped, and the cleaning section 120 of the floor cleaning equipment is controlled to rotate, so that the cleaning section 120 is cleaned.

[0113] When the amount of cleaning liquid in the cleaning liquid storage part of the floor cleaning device is less than a preset value, the second pump 140 is activated to pump the cleaning liquid in the base station 200 into the cleaning liquid storage part 110 of the floor cleaning device.

[0114] Accordingly, when the second pump 140 is started to pump the cleaning liquid in the base station 200 to the cleaning liquid storage part 110 of the floor cleaning device, the second pump 140 is stopped when the amount of the cleaning liquid in the cleaning liquid storage part 110 is greater than or equal to a preset value.

[0115] Furthermore, while the cleaning liquid is supplied to the cleaning portion 120 of the floor cleaning apparatus through the first pump 130 , the cleaning liquid in the base station 200 is pumped into the cleaning liquid storage portion 110 of the floor cleaning apparatus.

[0116] For example, when the second pump 140 has filled the cleaning liquid storage section 110 with cleaning liquid, the first pump 130 works to pump water from the cleaning liquid storage section 110, and the cleaning liquid is supplied to the cleaning section 120 to clean the cleaning section 120; at this time, due to the negative pressure in the cleaning liquid storage section 110, under the action of the negative pressure, the cleaning liquid in the cleaning liquid supply section 210 of the base station can be sucked into the cleaning liquid storage section 110, thereby keeping the amount of cleaning liquid in the cleaning liquid storage section 110 unchanged, for example, always keeping it in a full water state, so that the cleaning liquid storage section 110 of the ground cleaning equipment can remain dynamically full of water. After self-cleaning is completed, it can be directly separated from the base station for indoor cleaning without the need to wait for water to be supplied to the cleaning liquid storage section.

[0117] Moreover, it can be seen from the above working process that no matter when starting the second pump water replenishment process or starting the first pump water replenishment process during the self-cleaning process, the second pump does not contact water, which can correspondingly extend the service life of the second pump.

[0118] In the present disclosure, the relative position between the cleaning liquid supply unit 210 of the base station and the cleaning liquid storage unit 110 of the floor cleaning device can be appropriately set according to actual needs. For example, when the cleaning liquid supply unit 210 of the base station is lower than or flush with the cleaning liquid storage unit 110 of the floor cleaning device, the cleaning liquid can be drawn from the cleaning liquid supply unit 210 to the cleaning liquid storage unit 110 through negative pressure. On the other hand, when the cleaning liquid supply unit 210 is higher than the cleaning liquid storage unit 110, a siphon effect is formed between the cleaning liquid supply unit 210 and the cleaning liquid storage unit 110. In this case, the cleaning liquid can be drawn from the cleaning liquid supply unit 210 to the cleaning liquid storage unit 110 through negative pressure or siphoning.

[0119] In the present disclosure, the drying module can provide hot air to the cleaning unit 120 and dry the cleaning unit 120 with the hot air. Preferably, the drying module is provided in at least one of the base station 200 and the floor cleaning device. The structure of the drying module is already known in the art and will not be described in detail here.
