Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] The cleaning equipment provided by this utility model will be described in detail below with reference to the embodiments.

[0025] Please see Figure 1 and Figure 2 , Figure 1 This is a first partial schematic diagram of an embodiment of the cleaning equipment of this application; Figure 2 This is a block diagram of an embodiment of the cleaning device of this application. This application provides a cleaning device. The cleaning device 10 includes a cleaning device body 11, a mopping assembly 12, a clean water tank 13, a power drive unit 14, and an air supply unit (not shown in the figure). The mopping assembly 12 is connected to the bottom of the cleaning device body 11. The clean water tank 13 is disposed on the cleaning device body 11. The power drive unit 14 is disposed on the cleaning device body 11 and is closably connected to the clean water tank 13. The air supply unit is closably connected between the power drive unit 14 and the mopping assembly 12.

[0026] The cleaning device 10 can be, but is not limited to, a robotic vacuum cleaner, a robotic mop, a combined vacuum and mop, or a floor scrubber. The mopping component 12 can be, but is not limited to, a mopping roller, a mopping disc, or a roller brush. The mopping component 12 can be detachably or fixedly connected to the bottom of the cleaning device body 11. The mopping component 12 can clean the surface to be cleaned (not shown in the figure) by rolling or rotating. The surface to be cleaned can be, but is not limited to, floors and carpets.

[0027] The clean water tank 13 stores clean water. The clean water tank 13 can be detached or fixedly connected to the cleaning equipment body 11.

[0028] The power drive unit 14 can be detachably or fixedly attached to the cleaning device body 11. The power drive unit 14 can be in a connected state with the clean water tank 13; alternatively, the power drive unit 14 can be in a closed state with the clean water tank 13. When the power drive unit 14 is in a connected state with the clean water tank 13, the power drive unit 14 can draw clean water from the clean water tank 13 to the mopping assembly 12. The aforementioned power drive unit 14 can be, but is not limited to, a water pump or a centrifugal pump.

[0029] The air supply unit is detachably or fixedly connected to the cleaning equipment body 11. The air supply unit may be connected between the power drive unit 14 and the clean water tank 13; alternatively, the air supply unit may not be connected to either the power drive unit 14 or the clean water tank 13. When the air supply unit is connected between the power drive unit 14 and the clean water tank 13, clean water in the clean water tank 13 is drawn out through the power drive unit 14 to the mopping assembly 12, and the air supply unit is used to pressurize the clean water drawn into the mopping assembly 12. The air supply unit may be, but is not limited to, at least one of an air compressor, an air pump, and an air cylinder.

[0030] Through the combined action of the cleaning device body 11, mopping assembly 12, clean water tank 13, power drive component 14, and air supply component, when the power drive component 14 draws clean water from the clean water tank 13 into the mopping assembly 12, the air supply component can pressurize the clean water drawn into the mopping assembly 12. This not only allows the clean water tank 13 to dispense water evenly, improving cleaning quality and thus enhancing the user experience, but also makes the structure simple and easy to implement.

[0031] Continue reading Figure 1 and Figure 2 In some embodiments, a first clean water line 181 connects the mopping assembly 12 and the power drive unit 14. An air supply unit is connectable to the first clean water line 181 in an on / off manner.

[0032] The power drive unit 14 directs clean water from the clean water tank 13 into the mopping assembly 12 via the first clean water pipe 181. The air supply unit can be connected to the first clean water pipe 181 to pressurize the clean water in the first clean water pipe 181. Alternatively, the air supply unit can be disconnected from the first clean water pipe 181, in which case it does not provide pressurized gas.

[0033] Furthermore, a second clean water pipe 182 connects the power drive unit 14 and the clean water tank 13. Clean water in the clean water tank 13 can be drawn into the power drive unit 14 through the second clean water pipe 182, and then drawn out through the power drive unit 14 to the mopping assembly 12, etc.

[0034] By connecting the air supply component to the first clean water pipeline 181 in an openable and closable manner, the pressure in the first clean water pipeline 181 can be controlled, which not only makes the water outlet of the first clean water pipeline 181 uniform, improving the cleaning quality and thus improving the user experience; but also has a simple structure and is easy to implement and operate.

[0035] In some embodiments, the cleaning device 10 includes a wastewater tank 15 and a negative pressure component 16 disposed on the cleaning device body 11. One end of the negative pressure component 16 is openably connected to the wastewater tank 15, and the other end is openably connected between the power drive component 14 and the mopping assembly 12.

[0036] The wastewater tank 15 is detachable or fixed to the cleaning equipment body 11. The wastewater tank 15 can store wastewater and dirt. The negative pressure component 16 is detachable or fixed to the cleaning equipment body 11. One end of the negative pressure component 16 can be connected to one end of the wastewater tank 15; or, one end of the negative pressure component 16 can be disconnected from the wastewater tank 15. The other end of the negative pressure component 16 can be connected between the power drive component 14 and the mopping assembly 12; or, the other end of the negative pressure component 16 can be disconnected from both the power drive component 14 and the mopping assembly 12. The negative pressure component 16 may include, but is not limited to, an air pump.

[0037] When one end of the negative pressure component 16 is connected to the wastewater tank 15, and the other end of the negative pressure component 16 is connected between the power drive component 14 and the mopping assembly 12, the negative pressure component 16 can create a negative pressure state inside the wastewater tank 15, thereby allowing wastewater and dirt near the mopping assembly 12 to be smoothly drawn into the wastewater tank 15. When the negative pressure component 16 creates a negative pressure state inside the wastewater tank 15, the gas generated by the negative pressure component 16 can enter between the power drive component 14 and the mopping assembly 12 to pressurize the clean water drawn into the mopping assembly 12. For example, the gas generated by the negative pressure component 16 can enter the aforementioned first clean water pipe 181.

[0038] By introducing the gas generated by the negative pressure component 16 between the power drive component 14 and the mopping assembly 12, the clean water drawn into the mopping assembly 12 can be pressurized, which not only enables the clean water tank 13 to output water evenly, improving the cleaning quality and thus enhancing the user experience; but also has a simple structure and is easy to implement and operate, while improving the reusability of the negative pressure component 16, thereby reducing costs.

[0039] In some embodiments, the air supply component is a negative pressure component 16.

[0040] The cleaning device 10 may include an air supply component. Alternatively, the cleaning device 10 may include a negative pressure component 16. Alternatively, the cleaning device 10 may include both an air supply component and a negative pressure component 16.

[0041] When the air supply component is a negative pressure component 16, it not only improves the reusability of the negative pressure component 16, thereby reducing costs, but also has a simple structure and is easy to implement and operate.

[0042] Please see Figure 3 and Figure 4 , Figure 3 This is a second partial schematic diagram of an embodiment of the cleaning equipment of this application; Figure 4 yes Figure 3 An enlarged schematic diagram of A is shown below. (Combined with...) Figures 1 to 2 In some embodiments, the other end of the negative pressure member 16 is connected to an air outlet pipe 183. The air outlet pipe 183 is connected to a first clean water pipe 181. The air outlet pipe 183 is higher than the first clean water pipe 181.

[0043] The air outlet pipe 183 is connected between the other end of the negative pressure component 16 and the first clean water pipe 181. The overall height of the air outlet pipe 183 in the cleaning equipment body 11 can be higher than the overall height of the first clean water pipe 181 in the cleaning equipment body 11.

[0044] By limiting the height relationship between the above-mentioned air outlet pipe 183 and the first clean water pipe 181, it is not only more conducive to the gas pressurizing the clean water in the first clean water pipe 181 through the air outlet pipe 183, but also to improving the uniform water output from the outlet of the first clean water pipe 181, thereby improving the cleaning quality and thus improving the user experience; it can also reduce the risk of clean water entering the air outlet pipe 183.

[0045] In some embodiments, the cleaning device 10 includes a three-way valve 17. The three-way valve 17 is disposed and connected to the mopping assembly 12. A first water line 181 and an air outlet line 183 are both connected to the three-way valve 17.

[0046] The three-way valve 17 is detachably or fixedly connected to the mopping assembly 12. For example, the three-way valve 17 can be connected to the outer periphery of the roller (not shown in the figure) of the mopping assembly 12. When the three-way valve is connected to the mopping assembly 12, the three-way valve 17 can be opened and closed to the mopping assembly 12. For example, the three-way valve 17 can be connected to the mopping assembly 12; or, the three-way valve 17 can be disconnected from the mopping assembly 12. The first clean water pipe 181 and the air outlet pipe 183 can be opened and closed to the three-way valve 17. For example, the first clean water pipe 181 can be connected to the three-way valve 17; or, the first clean water pipe 181 can be disconnected from the three-way valve 17. Similarly, the air outlet pipe 183 can be connected to the three-way valve 17; or, the air outlet pipe 183 can be disconnected from the three-way valve 17, etc. The mopping assembly 12, the first water pipe 181, and the air outlet pipe 183 are respectively connected to or disconnected from the three-way valve 17, which can be determined according to the actual situation and is not limited here. The three-way valve 17 can be a conventional component, and its structure and principle are not limited.

[0047] By installing the three-way valve 17 on the mopping assembly 12 and connecting the first clean water pipe 181 and the air outlet pipe 183 to the three-way valve 17, not only is the stability of the installation of the first clean water pipe 181 and the air outlet pipe 183 improved, but also the clean water can smoothly enter the mopping assembly 12, while the air enters the three-way valve 17 and pressurizes the outlet of the first clean water pipe 181.

[0048] Continue reading Figures 1 to 4 In some embodiments, the end of the air outlet pipe 183 near the three-way valve 17 is higher than the end of the first clean water pipe 181 near the three-way valve 17.

[0049] The overall height of the vent pipe 183 may be higher than the overall height of the first clean water pipe 181; or, a portion of the vent pipe 183 may be higher than a portion of the first clean water pipe 181, as long as the outlet height of the vent pipe 183 is higher than the outlet height of the first clean water pipe 181, and no limitation is imposed here.

[0050] For example, when both the vent pipe 183 and the first clean water pipe 181 are connected to the three-way valve 17, the height relationship between the positions of the vent pipe 183 and the first clean water pipe 181 at the three-way valve 17 can be changed. For instance, the end of the vent pipe 183 near the three-way valve 17 is higher than the end of the first clean water pipe 181 near the three-way valve 17, meaning the outlet of the vent pipe 183 is positioned higher on the three-way valve 17 than the outlet of the first clean water pipe 181.

[0051] By limiting the height relationship between the air outlet pipe 183 and the first clean water pipe 181 on the three-way valve 17, it is not only more conducive to the gas pressurizing the clean water in the first clean water pipe 181 through the air outlet pipe 183, but also to improve the uniform water output from the outlet of the first clean water pipe 181, thereby improving the cleaning quality and enhancing the user experience; it also reduces the risk of clean water entering the air outlet pipe 183.

[0052] In some embodiments, the vent line 183 is provided with a one-way valve (not shown in the figure).

[0053] The one-way valve is detachably connected to the air outlet line 183. The detachable connection can be, but is not limited to, snap-fit ​​or plug-in connections. By installing the one-way valve in the air outlet line 183, the one-way valve can reduce backflow of clean water in the first clean water line 181, thereby reducing the risk of clean water entering the negative pressure component 16. The aforementioned one-way valve is a conventional component, and its structure is not limited.

[0054] Continue reading Figures 1 to 4In some embodiments, the power drive 14 is located in the clean water tank 13 and near the air supply unit. By defining the power drive 14 at the corresponding positions in the clean water tank 13 and the air supply unit, the stability of the power drive 14 in connection with the mopping assembly 12 can be improved.

[0055] In some embodiments, the power drive 14 includes a water pump. And / or, the air supply component includes at least one of an air compressor (not shown), a pneumatic pump (not shown), and a gas cylinder (not shown). And / or, the cleaning device body 11 is provided with a wastewater tank 111. A first wastewater pipe 185 is provided in communication between the wastewater tank 111 and the mopping assembly 12. A second wastewater pipe 186 is provided in communication between the wastewater tank 111 and the wastewater container 15.

[0056] In this embodiment, the power drive component 14 includes a water pump (not shown in the figure), as in this example. In other embodiments, the power drive component 14 may include a centrifugal pump (not shown in the figure), etc.

[0057] The gas supply unit may include one, two, or all three of the following: an air compressor, a pressure pump, and a gas cylinder. For example, the gas supply unit may include an air compressor; or, it may include an air compressor and a pressure pump; or, it may include an air compressor, a pressure pump, and a gas cylinder, etc., which will not be elaborated further here. The aforementioned air compressor, pressure pump, and gas cylinder are all conventional components in this field and will not be limited thereto.

[0058] Under the suction of the negative pressure component 16, the wastewater and stains generated by the mopping assembly 12 enter the wastewater tank 111 through the first wastewater pipe 185; simultaneously, the wastewater and stains in the wastewater tank 111 enter the wastewater container 15 through the second wastewater pipe 186. Through the combined action of the first wastewater pipe 185 and the second wastewater pipe 186, the wastewater and stains generated by the mopping assembly 12 can more easily enter the wastewater container 15.

[0059] In some specific application scenarios, the negative pressure component 16 operates, drawing air out of the wastewater tank 15 and sequentially passing it through the air inlet pipe 184, the negative pressure component 16, and the air outlet pipe 183. The gas in the air outlet pipe 183 is then introduced into the first clean water pipe 181 between the power drive component 14 and the mopping assembly 12 to pressurize the first clean water pipe 181, ensuring even water flow from its outlet. This method not only facilitates the pressurization of the clean water through the first clean water pipe 181, improving the even water flow and thus enhancing cleaning quality and user experience, but also reduces the risk of clean water entering the air outlet pipe 183.
