DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and advantages of the present disclosure more clear, the present disclosure will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present disclosure, rather than all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort are intended to fall within the scope of protection of the present disclosure.

[0033] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The singular forms of "a", "the" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise, and "multiple" generally includes at least two. The "first" and "second" modifiers in front of the terms are used to distinguish between the terms for the convenience of describing the terms, and do not indicate that there is a sequence or relative importance between the terms.

[0034] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0035] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or device. In the absence of further limitations, an element defined by the phrase "comprising a" does not exclude the presence of other identical elements in the product or device comprising the element.

[0036] The water tanks used in related-art self-propelled cleaning devices have a water outlet directly on the bottom. When air is introduced into the tank, the liquid in the tank flows directly out of the bottom. If the tank leaks or the water inlet is not tightly sealed, the atmospheric pressure inside and outside the tank becomes the same, and gravity forces the cleaning liquid out of the outlet. This can cause the cleaning components of the self-propelled cleaning device to become overfilled with water, or the liquid can overflow directly into the area being cleaned. Furthermore, the water tank quickly becomes dehydrated, forcing the self-propelled cleaning device to frequently refill its water tank, making it impossible to clean areas further away from the refill point.

[0037] The technical solution of the present disclosure can solve at least one of the technical problems mentioned above. The optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0038] FIG1 is a schematic structural diagram of a self-moving cleaning device provided in some embodiments of the present disclosure.

[0039] FIG. 2 is a schematic diagram of the bottom structure of the self-moving cleaning device shown in FIG. 1 .

[0040] As shown in Figures 1 and 2, a self-moving cleaning device 600, such as a sweeping robot, may include steering wheels 620 and drive wheels 630. The self-moving cleaning device 600 can move on a supporting surface, such as the ground, under the action of the steering wheels 620 and the drive wheels 630. Optionally, the self-moving cleaning device 600 can move along a pre-set route, and in certain circumstances, such as when the self-moving cleaning device 600 itself is low on power, its dust box is full of garbage, and the cleaning task is completed, the self-moving cleaning device 600 can move back to the dust collection charging station to complete charging or unload the garbage into the dust collection container.

[0041] The self-mobile cleaning device 600 may also include charging electrodes 640, configured to electrically connect to the dust collection charging station to charge the self-mobile cleaning device 600 after the self-mobile cleaning device 600 returns to the dust collection charging station. As shown in Figure 2, in some embodiments, the charging electrodes 640 are disposed on the bottom surface of the self-mobile cleaning device 600, for example, two charging electrodes 640, one on each side of the steering wheel 620. Those skilled in the art will appreciate that the above is merely an example of the number and location of the charging electrodes, and this disclosure does not specifically limit the number and location of the charging electrodes.

[0042] The self-mobile cleaning device 600 can also include a cleaning module 610, for example, a dry cleaning module. The cleaning module 610 is configured to clean at least a portion of a support surface, such as the ground, when the self-mobile cleaning device 600 moves on the support surface, such as the ground. In certain embodiments, as shown in Figure 2, the cleaning module 610 is, for example, arranged between two driving wheels 630. The cleaning module 610 can specifically include a frame 612 and a roller brush 611 arranged in the frame 612, and a plurality of scraping strips 6111 are provided on the periphery of the roller brush 611. The frame 612 has a vent 6121, which exposes at least a portion of the roller brush 611.

[0043] When the self-mobile cleaning device 600 performs a cleaning operation, the roller brush 611 rotates, and the scraper bar 6111 exposed on it by the frame 612 can contact the ground. At the same time, the fan in the self-mobile cleaning device 600, such as a dust suction fan, generates an airflow that enters the frame 612 through the vent 6121. Under the action of the scraper bar 6111 and the airflow, the garbage will enter the frame 612 through the vent 6121 and then be collected in the dust box of the self-mobile cleaning device 600. The vent 6121 also serves as a garbage circulation port. That is to say, when the self-mobile cleaning device 600 performs a cleaning operation, the vent 6121 serves as the dust suction port of the self-mobile cleaning device 600.

[0044] FIG3 is a schematic structural diagram of a self-moving cleaning device provided in some embodiments of the present disclosure without a dust box installed.

[0045] As shown in Figure 3, the self-mobile cleaning device 600 also includes a dust suction fan 660. Since the dust suction fan 660 is located inside the self-mobile cleaning device 600, it is not shown in the figure. The dust suction fan 660 is configured to provide a suction power source for the self-mobile cleaning device 600 during cleaning operations, generating an airflow. When the self-mobile cleaning device 600 performs a cleaning operation, the airflow generated by the dust suction fan 660 drives garbage into the frame 612 through the vent 6121 and is then collected in the dust collection box 670 of the self-mobile cleaning device 600.

[0046] The self-mobile cleaning device 600 has a storage space 650, which is configured to accommodate the dust box 670. A second opening 651 and a vent 652 are provided on the side wall of the storage space 650, and both the second opening 651 and the vent 652 are connected to the outside world. When the self-mobile cleaning device 600 is performing cleaning work, garbage enters the dust box 670 through the vent 6121 and the second opening 651; the vent 652 is configured to allow external air to enter the dust box 670 through the vent 652 when the self-mobile cleaning device 600 returns to the dust collection charging station 700 for dust collection.

[0047] FIG4 is a schematic structural diagram of a dust collection charging pile provided in some embodiments of the present disclosure.

[0048] The dust collection charging pile 700 integrates a charging pile and a dust collection pile, and is configured to provide energy supply and garbage collection for the self-moving cleaning equipment.

[0049] As shown in Figure 4, the dust collection charging pile 700 includes a dust collection charging pile base 710 and a dust collection charging pile body 720. The dust collection charging pile body 720 is configured to charge the self-mobile cleaning device 600 and collect garbage in the dust box 670 of the self-mobile cleaning device 600, and is arranged on the dust collection charging pile base 710. The dust collection charging pile body 720 includes a dust collection container 722 and a dust collection fan 723. The dust collection container 722 is, for example, in the form of a drum, and is configured to recycle garbage in the dust box 670 of the self-mobile cleaning device 600. The dust collection fan 723 is connected to the air outlet provided in the dust collection container 722 to provide power to recycle the garbage in the dust box 670 of the self-mobile cleaning device 600 into the dust collection container 722.

[0050] The dust collection charging pile 700 includes a charging connector 721 and a dust suction port 711. The charging connector 721 is configured to supply energy to the self-mobile cleaning device 600. The dust suction port 711 is configured to connect with the dust outlet of the self-mobile cleaning device 600 (when the self-mobile cleaning device 600 discharges dust into the dust collection charging pile 700, the vent 6121 in the self-mobile cleaning device 600 serves as the dust outlet). The garbage in the dust box 670 of the self-mobile cleaning device 600 enters the dust collection container 722 of the dust collection charging pile body 720 through the dust suction port 711. For example, as shown in Figure 4, the charging connector 721 is provided on the dust collection charging pile body 720, and the dust suction port 711 is provided on the dust collection charging pile base 710. In some embodiments, as shown in Figure 4, a sealing rubber gasket 712 is further provided around the dust suction port 711 to seal the dust suction port 711 after connecting with the dust outlet of the self-mobile cleaning device 600 to prevent garbage leakage.

[0051] The air inlet of the dust collecting container 722 is connected to the dust suction port 711 through the dust collecting air path 713. Under the action of the airflow generated by the dust collecting fan 723, the garbage in the dust collecting box 670 in the self-moving cleaning device 600 can pass through the ventilation port 6121 in the self-moving cleaning device 600 and be collected in the dust collecting container 722 via the dust collecting air path 713.

[0052] FIG5 is a schematic diagram of a scene after a self-mobile cleaning device returns to a dust collection charging station according to some embodiments of the present disclosure.

[0053] As shown in Figure 5, when the self-mobile cleaning device 600, such as a sweeping robot, returns to the dust collection charging pile 700 after cleaning, the self-mobile cleaning device 600 will move along the first direction X to the dust collection charging pile base 710, so that the charging electrode 640 on the self-mobile cleaning device 600 is electrically connected to the charging connector 721 to charge the self-mobile cleaning device 600, and the dust outlet of the self-mobile cleaning device 600, that is, the ventilation port 6121 is docked with the dust suction port 711 of the dust collection charging pile 700 to transfer the garbage in the dust box 670 of the self-mobile cleaning device 600 to the dust collection container 722 of the dust collection charging pile 700.

[0054] FIG6 is a schematic diagram of a water tank provided in some embodiments of the present disclosure.

[0055] FIG7 is a schematic diagram of a water tank provided in some other embodiments of the present disclosure, wherein the flow direction of the cleaning liquid through the inverted U-shaped water outlet pipe is shown in the figure.

[0056] As shown in Figures 6 and 7, according to specific embodiments of the present disclosure, in a first aspect, a water tank for use in an automatic cleaning device is provided, which may include: a box body 810, wherein the box body 810 includes: a bottom plate 813; the interior space of the box body 810 is provided with a water storage chamber 814; wherein an inverted U-shaped water outlet pipe 815 is provided within the box body 810, wherein the water inlet of the inverted U-shaped water outlet pipe 815 is located near the bottom plate 813 and communicates with the water storage chamber 814, and the water outlet 8152 of the inverted U-shaped water outlet pipe 815 is located on the bottom plate 813 and communicates with the outside of the box body 810. In some embodiments, the box body 810 may further include: a top plate 811 and sidewalls 812. In an optional embodiment, the box body 810 is provided with a water inlet 8111, through which the cleaning liquid flows into the water storage chamber 814.

[0057] The water tank 800 of the present disclosure has an inverted U-shaped water outlet pipe 815 disposed therein. When cleaning liquid is needed, air is pumped into the water tank 800, and the cleaning liquid enters through a water inlet 8151 of the inverted U-shaped water outlet pipe 815 disposed at the bottom of the water tank 800 and flows out through a water outlet 8152. The cleaning liquid in the water tank 800 flows out through the inverted U-shaped water outlet pipe 815, so the cleaning liquid does not flow out on its own.

[0058] In actual application, the water tank 800 is installed on the automatic cleaning device, and then the cleaning liquid is injected into the water storage chamber 814 through the water injection port 8111 (or the cleaning liquid is first injected into the water storage chamber 814 through the water injection port 8111 and then the water tank 800 is installed on the automatic cleaning device). It should be noted that during the installation of the water tank 800 on the automatic cleaning device and during the operation of the automatic cleaning device, the top plate 811 faces upward and the bottom plate 813 faces downward. When the automatic cleaning device needs to use cleaning liquid for cleaning, the air pump 820 is turned on and pumps air into the water storage chamber 814 through the air pump tube 850. At this time, the pressure of the air part in the box body 810 is greater than the external pressure, so that the cleaning liquid enters from the water inlet 8151 of the inverted U-shaped water outlet pipe 815, and the cleaning liquid flows out from the water outlet 8152 of the inverted U-shaped water outlet pipe 815, and finally acts on the cleaning components of the automatic cleaning device.

[0059] It should be noted that even if the water tank 800 leaks or the water inlet 8111 is not sealed tightly, the liquid in the water storage chamber 814 will not flow out on its own, thereby affecting the operation of the automatic cleaning device.

[0060] FIG8 is a schematic diagram of an inverted U-shaped water outlet pipe 815 provided in some embodiments of the present disclosure.

[0061] As shown in FIG8 , in some embodiments, the inverted U-shaped water outlet pipeline 815 may include a first pipeline 8153 and a third pipeline 8155 connected end to end, wherein the water inlet 8151 is located at an end of the first pipeline 8153 near the bottom plate 813, and the water outlet 8152 is located at the connection between the third pipeline 8155 and the bottom plate 813. In an optional embodiment, the inverted U-shaped water outlet pipeline 815 may further include a second pipeline 8154 located between the first pipeline 8153 and the third pipeline 8155. For example, the first pipeline 8153, the second pipeline 8154, and the third pipeline 8155 are connected end to end. The first pipeline 8153 is the first section of the inverted U-shaped water outlet pipeline 815 (i.e., the first vertical pipe of the U shape), extending from the water inlet 8151 near the bottom plate 813 toward the top plate 811; the second pipeline 8154 is the second section of the inverted U-shaped water outlet pipeline 815 (i.e., the pipe connecting the first vertical pipe with the second vertical pipe in the U shape), connected from the water outlet end of the first pipeline 8153 to the water inlet end of the third pipeline 8155; the third pipeline 8155 is the third section of the inverted U-shaped water outlet pipeline 815 (i.e., the second vertical pipe of the U shape), extending from the top plate 811 toward the water outlet 8152 near the bottom plate 813.

[0062] In actual application, when the automatic cleaning device needs to use cleaning liquid for cleaning, the air pump 820 is turned on and pumps air into the water storage chamber 814 through the air pump tube 850. At this time, the pressure of the air in the box body 810 is greater than the external pressure, so that the cleaning liquid enters from the water inlet 8151 of the first pipeline 8153 and flows through the first pipeline 8153; then, it flows from the water outlet end of the first pipeline 8153 to the second pipeline 8154 and flows through the second pipeline 8154; then, it flows from the water outlet end of the second pipeline 8154 to the third pipeline 8155, flows through the third pipeline 8155, and then flows out from the water outlet 8152, finally acting on the cleaning components of the automatic cleaning device.

[0063] In some embodiments, at least a portion of the top of the second pipeline 8154 is an open structure, and the top plate 811 of the box body 810 is covered on the top of the open structure.

[0064] In some embodiments, only the water inlet 8151 of the inverted U-shaped water outlet pipe 815 is connected to the water storage chamber 814 .

[0065] In some embodiments, the straight-line distance between the end of the second pipeline 8154 close to the first pipeline 8153 and the top plate 811 is a first distance, and the straight-line distance between the end of the second pipeline 8154 close to the third pipeline 8155 and the top plate 811 is a second distance, and the second distance is greater than the first distance.

[0066] If the top of the second pipe 8154 is open, the high pressure of the air in the water storage chamber 814 cannot act on the second pipe 8154. Therefore, gravity is required to cause the cleaning liquid to flow from the water inlet of the second pipe 8154 to the water outlet of the second pipe 8154 (the third pipe 8155). In actual use, the top plate 811 is facing upward, and the second distance is greater than the first distance, that is, the water inlet of the second pipe 8154 is higher than the water outlet of the second pipe 8154, so that the cleaning liquid flows through the second pipe 8154.

[0067] In some embodiments, the inverted U-shaped water outlet pipe 815 is provided with an air vent 8112 at one end thereof near the top plate 811. With the inverted U-shaped water outlet pipe 815 structure disclosed herein, during use, cleaning liquid forms a closed structure within the inverted U-shaped water outlet pipe 815, generating a siphon effect that can cause some liquid in the water storage chamber 814 to be lost. The air vent 8112 prevents this siphon effect.

[0068] In some embodiments, the box body 810 may further include an air vent 8112 , which is disposed on the top plate 811 of the box body 810 and communicates with the open structure.

[0069] In actual application, the cleaning liquid forms a closed structure in the inverted U-shaped water outlet pipe 815, generating a siphon effect, which will cause part of the liquid in the water storage chamber 814 to be lost. Because the air vent 8112 is provided, the siphon effect is prevented. In an optional embodiment, the projection of the air vent 8112 on the bottom plate 813 overlaps with the projection of the third pipe 8155 on the bottom plate 813. In another optional embodiment, the air vent 8112 is provided at a first position, the first position is located on the side of the second position away from the first pipe 8153, and the first position is adjacent to the second position; the second position is the projection of the third pipe 8155 on the top plate 811. In an optional embodiment, the top plate 811 may include: a water baffle, the water baffle is located between (or adjacent to) the first position and the second position, and the water baffle is located on the side of the top plate 811 close to the bottom plate 813. It should be noted that the air hole 8112 is intended to prevent a siphon effect, but the cleaning liquid is also likely to flow out of the air hole 8112. Therefore, a water baffle is provided between the air hole 8112 and the third pipe 8155 (projection on the top plate 811) to prevent the cleaning liquid from flowing out of the air hole 8112.

[0070] In some embodiments, the second pipeline 8154 and the third pipeline 8155 may include at least two water channels, and the water channels are connected to the water outlet 8152.

[0071] In some embodiments, the third pipeline 8155 includes at least two water channels, the number of the water outlets 8152 corresponds to the number of the water channels, and each water channel is connected to one water outlet 8152 .

[0072] In some embodiments, the second pipeline 8154 includes at least two water channels, and the number of water channels in the second pipeline 8154 is the same as the number of water channels in the third pipeline 8155 .

[0073] The water outlet 8152 will eventually act on the cleaning components (such as a cleaning mop) of the automatic cleaning device. Most of the cleaning components basically extend along the width direction of the automatic cleaning device. Therefore, setting up multiple water channels can supply water at different positions of the cleaning components, so that the cleaning liquid on the cleaning components is evenly distributed.

[0074] It should be noted that the use of a water channel and the installation of an existing liquid spreading device can also play the same role, but considering the actual use of the automatic cleaning device, the use of a water channel and the installation of a liquid spreading device will make the cleaning liquid applied to the cleaning roller brush uneven. During the use of the automatic cleaning device, the cleaning roller brush absorbs the cleaning liquid, so the flow rate of the cleaning liquid needs to be very slow. If a liquid spreading device is used, more cleaning liquid will flow out of the water outlet point close to the water outlet 8152 on the liquid spreading device, and very little or even no cleaning liquid will flow out of the water outlet point far away from the water outlet 8152. In summary, the present disclosure adopts multiple water channels to act on the cleaning roller brush at the same time, so that the cleaning liquid absorbed by the cleaning roller brush is uniform, thereby improving the cleaning efficiency.

[0075] In some embodiments, the water tank 800 may further include an air pump 820 disposed outside the box body 810, and configured to pump air into the water storage chamber 814. When the automatic cleaning device requires cleaning fluid, the air pump 820 is activated to pump air into the water storage chamber 814. At this point, the pressure of the air within the water storage chamber 814 is greater than the external pressure, causing the cleaning fluid to enter through the water inlet 8151 of the inverted U-shaped water outlet pipe 815, and then flow out through the water outlet 8152 of the inverted U-shaped water outlet pipe 815, ultimately acting on the cleaning components of the automatic cleaning device.

[0076] In some embodiments, the water tank 800 may include an air pump tube 850 , which is at least partially disposed in the box body 810 , with one end of the air pump tube 850 connected to the air pump 820 and the other end extending to near the water inlet 8151 .

[0077] When the automatic cleaning device needs to use cleaning liquid for cleaning, the air pump 820 starts to operate and pumps air into the water storage chamber 814 through the air pump tube 850. At this time, the pressure of the air in the water storage chamber 814 is greater than the external pressure, causing the cleaning liquid to enter through the water inlet 8151 of the inverted U-shaped water outlet pipe 815, and the cleaning liquid flows out through the water outlet 8152 of the inverted U-shaped water outlet pipe 815, ultimately acting on the cleaning components of the automatic cleaning device.

[0078] In some embodiments, the water tank 800 may further include a water filling cover 830, which is detachably connected to the top plate 811. When the cleaning liquid needs to be injected into the water storage chamber 814, the water filling cover 830 is opened and the cleaning liquid is injected into the water storage chamber 814. After the injection is completed, the water filling cover 830 is closed.

[0079] In some embodiments, a sealing plug is provided on one side of the water filling cover plate 830 near the top plate 811. When the water filling cover plate 830 is closed, the sealing plug seals the water filling port 8111. When the air pump 820 is used to supply air to the water storage chamber 814, it is necessary to keep the air portion of the water storage chamber 814 sealed. The sealing plug is used to improve the sealing state of the water storage chamber 814.

[0080] In some embodiments, the water tank 800 may further include: a vent baffle, which is reversibly disposed at the vent hole 8112. A water pump, which is disposed at the water inlet 8151 and is used to pump cleaning liquid in the water tank 800 into the inverted U-shaped water outlet pipe 815. The vent baffle is disposed between the vent hole 8112 and the second pipe 8154, and does not block the vent hole 8112 and the second pipe 8154 when the vent baffle is open or closed.

[0081] In some embodiments, the water tank 800 may further include a water filling filter 840 disposed at the water filling port 8111 for filtering liquid entering the water storage chamber 814. When the cleaning liquid needs to be injected into the water storage chamber 814, the water filling cover 830 is opened and the cleaning liquid is injected into the water storage chamber 814. The injected cleaning liquid passes through the water filling filter 840 and enters the water storage chamber 814, preventing impurities in the cleaning liquid from entering the water storage chamber 814 and causing blockage of the inverted U-shaped water outlet pipe 815.

[0082] FIG9 is a schematic diagram of a water tank 800 provided in some other embodiments of the present disclosure.

[0083] As shown in FIG9 , the water tank 800 may further include a dust collecting box 670 , and the dust collecting box 670 is provided with an air outlet and a collection port.
