[0022] In order to clarify the objectives, technical solutions and advantages of the present disclosure, the present disclosure will be described in more detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present disclosure, and not all of the embodiments. Based on the embodiments of the present disclosure, other embodiments that can be obtained by those skilled in the art without any creative work are all included in the protection scope of the present disclosure.

[0023] It should be noted that the terms "comprises," "has," or any other variation thereof are intended to cover a non-exclusive inclusion, and a product or device comprising a set of elements includes not only those elements but also other elements not expressly listed or inherent in such product or device. Unless further qualified, the fact that a definition is made with the phrase "comprising one or more" does not exclude the presence of other elements of the same type in the product or device of said elements.

[0024] The present disclosure provides a storage appliance for an automatic cleaning device, applicable to, for example, a sweeping robot, comprising: a box body having a storage space and a partition wall for dividing the storage space into a dust box space and a water tank space; a top cover configured to cover the box body and seal the storage space; and a one-way valve assembly provided on a wall of the box body, the one-way valve assembly being in a closed state in response to an external force applied to the one-way valve assembly being equal to or smaller than a threshold value, thereby isolating the dust box space from the outside at the position of the one-way valve assembly, and transitioning from the closed state to an open state in response to an external force applied to the one-way valve assembly being greater than the threshold value, thereby allowing the dust box space to communicate with the outside at the position of the one-way valve assembly.

[0025] An automatic cleaning device using this storage appliance can be used in combination with a dust collection pile. When the automatic cleaning device performs its cleaning operation, the one-way valve assembly of the storage appliance is closed, and the fan within the automatic cleaning device sucks dust and other debris through the storage appliance's dust inlet / outlet port, such as the first opening, into the dust box, collecting the debris in the dust box during the automatic cleaning device's cleaning operation. When the automatic cleaning device returns to the dust collection pile and connects to it to collect debris from the dust box into the dust collection pile, the one-way valve assembly changes from the closed state to an open state under the suction force of the fan within the dust collection pile and / or the fan of the automatic cleaning device, forming an air inlet for the dust box space, i.e., an air inlet for the entire airflow, and the dust and other debris in the dust box is transferred by airflow into the dust collection pile.

[0026] Selected embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0027] FIG. 1 is a structural schematic diagram of an automatic cleaning device provided by some embodiments of the present disclosure, and FIG. 2 is a schematic diagram of the bottom structure of the automatic cleaning device shown in FIG.

[0028] 1 and 2, the automatic cleaning device 100, such as a sweeping robot, has steering wheels 120 and driving wheels 130, which allow the automatic cleaning device 100 to move on a supporting surface, such as a floor, under the action of the steering wheels 120 and driving wheels 130. Optionally, the automatic cleaning device 100 can move along a preset path, and in certain situations, such as when the automatic cleaning device 100 runs out of power, when its own dust box is full of dust, or when the cleaning job is finished, the automatic cleaning device 100 can return to the dust collection charging pile to charge or discharge the dust into the dust collection container.

[0029] The automatic cleaning device 100 further includes a charging electrode 140 configured to be electrically connected to the dust collecting charging pile to charge the automatic cleaning device 100 after the automatic cleaning device 100 returns to the dust collecting charging pile. As shown in FIG. 2 , in some embodiments, the charging electrodes 140 are provided on the bottom surface of the automatic cleaning device 100, and the number of the charging electrodes is, for example, two, one on each side of the steering wheel 120. Those skilled in the art will understand that the above is merely an example of the number and installation positions of the charging electrodes, and the present disclosure does not particularly limit the number and installation positions of the charging electrodes.

[0030] The automatic cleaning device 100 further includes a cleaning module 110, e.g., a dry cleaning module. The cleaning module 110 is configured to clean at least a portion of a support surface, e.g., a floor surface, as the automatic cleaning device 100 moves over the support surface, e.g., a floor surface. In some embodiments, as shown in FIG. 2 , the cleaning module 110 is disposed between two drive wheels 130, for example. The cleaning module 110 specifically includes a frame 112 and a roller brush 111 disposed within the frame 112, with a plurality of scrapers 1111 disposed on the outer periphery of the roller brush 111. The frame 112 has an air vent 1121 for exposing at least a portion of the roller brush 111.

[0031] When the automatic cleaning device 100 performs a cleaning operation, the roller brush 111 rotates, and the scraper 1111 exposed by the frame 112 comes into contact with the floor surface. At the same time, a fan in the automatic cleaning device 100, for example the first fan, generates an airflow that enters the frame 112 through the air vent 1121. Under the action of the scraper 1111 and the airflow, dust enters the frame 112 through the air vent 1121 and is then collected in the dust box of the automatic cleaning device 100. The air vent 1121 also functions as a dust circulation port, that is, when the automatic cleaning device 100 performs a cleaning operation, the air vent 1121 functions as a dust suction port of the automatic cleaning device 100.

[0032] 3 is a structural schematic diagram of a storage device and an automatic cleaning device provided according to some embodiments of the present disclosure when not assembled. As shown in FIG. 3, the automatic cleaning device 100 further includes a first fan 160, which is not shown because it is located inside the automatic cleaning device 100. The first fan 160 is used to generate airflow as a power source for air suction when the automatic cleaning device 100 performs a cleaning operation. When the automatic cleaning device 100 performs a cleaning operation, the airflow generated by the first fan 160 causes dust to enter the frame 112 through the air vent 1121 and then be collected in the storage device of the automatic cleaning device 100.

[0033] The automatic cleaning device 100 has a storage space 150 configured to store the storage appliance. A second opening 151 and a vent 152 are provided on a side wall of the storage space 150, and the second opening 151 and the vent 152 are connected to the outside. When the automatic cleaning device 100 performs cleaning work, dust enters the storage appliance through the vent 1121 and the second opening 151, and the vent 152 is configured to allow external gas to enter the storage appliance through the vent 152 when the automatic cleaning device 100 returns to the dust collection charging pile 200 for dust collection.

[0034] FIG. 4 is a structural schematic diagram of a dust-collecting charging pile provided by some embodiments of the present disclosure, in which the dust-collecting charging pile 200 integrates a charging pile and a dust-collecting pile, and is configured to provide energy supply and garbage collection for the automatic cleaning device 100.

[0035] As shown in FIG. 4 , the dust-collecting charging pile 200 is composed of a dust-collecting charging pile base 210 and a dust-collecting charging main body 220. The dust-collecting charging main body 220 is configured to charge the automatic cleaning device 100 and collect dust within the storage device of the automatic cleaning device 100, and is installed on the dust-collecting charging pile base 210. The dust-collecting charging main body 220 includes a dust collection container 222 and a dust collection fan 223, also referred to as a second fan 223. The dust collection container 222 is, for example, cylindrical and is configured to collect dust within the storage device of the automatic cleaning device 100. The second fan 223 is connected to an air outlet installed in the dust collection container 222 and provides power for collecting dust within the storage device of the automatic cleaning device 100 into the dust collection container 222.

[0036] The dust-collecting charging pile 200 includes a charging connector 221 and a dust suction port 211. The charging connector 221 supplies energy to the automatic cleaning device 100, and the dust suction port 211 is connected to the dust discharge port of the automatic cleaning device 100 (when the automatic cleaning device 100 discharges dust into the dust-collecting charging pile 200, the vent 1121 in the automatic cleaning device 100 functions as the dust discharge port). Dust in the storage device of the automatic cleaning device 100 enters the dust collection container 222 of the dust-collecting charging main body 220 through the dust suction port 211. For example, as shown in FIG. 4 , the charging connector 221 is provided on the dust-collecting charging main body 220, and the dust suction port 211 is provided on the dust-collecting charging pile base 210. In some embodiments, as shown in FIG. 4 , a sealing rubber pad 214 is further provided around the dust suction port 211 to connect and seal the dust suction port 211 and the dust discharge port of the automatic cleaning device 100 and prevent dust leakage.

[0037] The air inlet of the dust collection container 222 is connected to the dust suction port 211 via the dust collection air duct 215, and under the action of the airflow generated by the second fan 223, dust in the storage equipment in the automatic cleaning device 100 can be collected from the air vent 1121 in the automatic cleaning device 100 through the dust collection air duct 215 into the dust collection container 222.

[0038] FIG. 5 is a schematic diagram of a scene after an automatic cleaning device provided in some embodiments of the present disclosure is returned to the dust collection charging pile. As shown in FIG. 5 , when the automatic cleaning device 100, such as a sweeping robot, finishes cleaning and returns to the dust collection charging pile 200, the automatic cleaning device 100 moves along the first direction X shown in FIG. 4 to the dust collection charging pile base 210, electrically connects the charging electrode 140 of the automatic cleaning device 100 to the charging connector 221 to charge the automatic cleaning device 100, and connects the dust exhaust port, i.e., the ventilation port 1121, of the automatic cleaning device 100 to the dust suction port 211 of the dust collection charging pile 200 to transfer the dust in the storage device of the automatic cleaning device 100 to the dust collection container 222 of the dust collection charging pile 200.

[0039] FIG. 6 is a schematic exploded view of a storage device according to some embodiments of the present disclosure. FIG. 7 is a schematic view of the structure of the box body of the storage device in FIG. 6. FIG. 8 is a schematic view of the structure of the box body in FIG. 7 from another perspective. As shown in FIGS. 6 to 8, storage device 300 includes box body 310 and top cover 320. In some embodiments, box body 310 and top cover 320 are non-detachably connected to enhance the sealing of box body 310. The box body is fitted to storage space 150 and provides dust storage and water storage functions for the automatic cleaning device. The box body may have a regular or irregular shape as long as it fits into the storage space. In some embodiments, the box body resembles a right-angled trapezoid, with the hypotenuse of the right-angled trapezoid replaced by a circular arc. This makes full use of space and facilitates the arrangement of other components according to the overall contour of the automatic cleaning device.

[0040] The box body 310 has a bottom wall 311 and side walls arranged around the edge of the bottom wall 311, the side walls extending away from the bottom wall 311, and the bottom wall 311 and the side walls enclose and define a storage space 312. The box body further includes a dividing wall 316, which divides the storage space 312 into a dust box space 3121 and a water tank space 3122.

[0041] An open oblique space 313 is provided at the bottom of the box body, and a portion of the bottom wall of the box body 310 and the side walls connected to this portion of the bottom wall are recessed inward toward the storage space to form the oblique space 313. This oblique space provides an installation space for the one-way valve assembly and prevents the one-way valve assembly from interfering with the storage space 150 and the water pipe in the water tank space. Furthermore, the oblique space provides freedom in selecting the installation position of the one-way valve assembly, allowing for better configuration of the position and opening direction of the one-way valve assembly, allowing the airflow to enter more smoothly and be closer to the side wall of the dust box space, contributing to the stirring up of all dust without any leakage.

[0042] 6 to 8, the oblique angle space 313 is located at a position where one corner of a rectangular parallelepiped is missing, and the oblique angle space has a first side wall 3131, a fourth side wall 3132, and a top wall 3133. The oblique angle space 313 is surrounded by the first side wall, the fourth side wall, and the top wall, and the oblique angle space 313 is adjacent to the dust box space via the first side wall of the oblique angle space, and the oblique angle space 313 is adjacent to the water tank space 3122 via the fourth side wall 3132 and the top wall 3133.

[0043] The side walls of the box body have a second side wall 314 and a third side wall 315, the second side wall 314 being adjacent to the first side wall 3131, the third side wall 315 being adjacent to the second side wall 314, and the first side wall 3131 being opposite the third side wall 315.

[0044] A first opening 3141 is provided on the second side wall 314, and in response to the storage device 300 being stored in the storage space 150, the second side wall 314 abuts against the side wall of the storage space 150, the first opening 3141 is sealably connected to the second opening 151, and the recessed space communicates with the ventilation hole 152. The first opening 3141 is a through-hole that serves as a passage for putting in and taking out dust from the storage space 312, and in response to the automatic cleaning device performing a cleaning operation, dust enters the dust box space 3121 through the first opening 3141, and in response to the automatic cleaning device performing a dust collection operation, the dust is discharged from the dust box space 3121 through the first opening 3141.

[0045] The dividing wall 316 extends from the bottom wall 311 of the box body toward the top cover 320, dividing the storage space into a dust box space 3121 and a water tank space 3122, thus realizing the integration of the dust box and the water tank in one device. Generally, the dust box is cleaned more frequently than the water tank is refilled, so a storage device with an integrated dust box and water tank with dust collection function can significantly reduce the frequency of removal of the storage device and avoid the problem of complicated operation.

[0046] The dust box space and the water tank space are arranged side by side in a direction parallel to the bottom wall of the box body. In this embodiment, the water tank space semi-encloses the dust box space. As shown in FIGS. 6 to 8 , the first side wall 3131 forms part of the partition wall 316, one end of the partition wall 316 is connected to the second side wall 314, and the other end of the partition wall 316 is connected to the third side wall 315, almost at the end farthest from the second side wall 314. Because water is heavier than dust, the entire lateral space of the box body is configured as the water tank space, thereby improving the stability of the automatic cleaning device 100. The shape of the partition wall 316 is not limited, as long as it divides the storage space into two spaces. The partition wall 316 has an irregular sheet shape, which divides the storage space into two spaces, while at the same time making the dust box space regular and maximizing its volume. Furthermore, it also functions to assist and guide the airflow into the dust box space and guide the airflow direction, so by setting a partition wall of a specific shape, dust can be more easily stirred up and discharged.

[0047] 8 , the partition wall 316 includes a first sub-divider wall 3161 parallel to the third side wall 315, a second sub-divider wall 3162 parallel to the second side wall 314, a third sub-divider wall 3163 connecting the first sub-divider wall to the second side wall, and a fourth sub-divider wall 3164 connecting the first sub-divider wall to the second sub-divider wall, wherein the fourth sub-divider wall extends from an end of the second side wall to an end of the third side wall and forms a certain angle with the second side wall and the third side wall, respectively, the third sub-divider wall divides the first opening and the vent hole, and the one-way valve assembly 340 is disposed in the first sub-divider wall. The third sub-divider wall, the first sub-divider wall, the fourth sub-divider wall, the second sub-divider wall, the third side wall, and the second side wall are sequentially connected to enclose and form the dust box space. When the one-way valve assembly 340 is in an open state, the airflow entering through the one-way valve assembly 340 flows obliquely along the fourth sub-dividing wall, forming a vortex more easily and quickly and stirring up all dust particles, which is superior to a directional dividing wall.

[0048] The one-way valve assembly 340 is installed on a first side wall of the oblique space. When the one-way valve assembly is in the closed state, the oblique space and the dust box space are isolated from each other. When the one-way valve assembly is transitioned from the closed state to the open state, the oblique space and the dust box space are interconnected. The external force is, for example, the suction force generated when the first fan 160 of the automatic cleaning device 100 and / or the second fan 223 of the dust collection charging pile 200 are activated. The threshold value is the critical value of the external force required to transition the one-way valve assembly 340 from the closed state to the open state. The one-way valve assembly 340 can be used to control the state and amount of communication between the oblique space and the dust box space, i.e., the amount of air entering.

[0049] In some embodiments, the power of the first fan 160 of the automatic cleaning device 100 is significantly lower than the power of the second fan 223 in the dust collecting charging pile 200, i.e., the suction force generated when the first fan 160 operates is significantly lower than the suction force generated when the second fan 223 operates. Specifically, when the automatic cleaning device 100 is performing a cleaning operation, i.e., when the automatic cleaning device 100 is in cleaning operation mode, the suction force generated when the first fan 160 operates is lower than the threshold, and the one-way valve assembly 340 is closed. Under the action of the airflow from the first fan 160, dust enters the frame 112 through the air vent 1121 and is further collected in the storage device 3121 of the automatic cleaning device 100. When the automatic cleaning device 100 is returned to and connected to the dust collecting charging pile 200 to collect dust from the storage appliances into the dust collecting container 222 in the dust collecting charging pile 200, specifically, the automatic cleaning device 100 moves in the first direction X toward the dust collecting charging pile base 210, sealingly connecting the dust discharge port, i.e., the air vent 1121, of the automatic cleaning device 100 to the dust suction port 211 of the dust collecting charging pile 200, and the second fan 223 in the dust collecting pile is put into operation. Under the suction force of the second fan 223, the one-way valve assembly 340 changes from the closed state to the open state. At this time, the one-way valve assembly 340 forms an air inlet on the storage appliance 3121, i.e., an air inlet for the entire airflow, and the airflow transfers the dust and other debris from the storage appliance 3121 into the dust collecting container 222 in the dust collecting charging pile 200.

[0050] In some embodiments, the automatic cleaning device 100 is placed on the dust collecting pile base 210 of the dust collecting charging pile 200 to collect dust in the storage fixtures 3121 into the dust collecting bin 222 in the dust collecting charging pile 200. That is, when the automatic cleaning device 100 is in dust discharge mode, the second fan 223 operates to generate strong suction force, and at the same time, the first fan 160 in the automatic cleaning device 100 also operates to prevent the strong suction force generated by the second fan from causing the first fan 160 in the automatic cleaning device 100 to rotate in the opposite direction and thereby causing damage to the first fan 160. At this time, the first fan and the second fan operate simultaneously, and the external force applied to the one-way valve assembly 340 is greater than the threshold, so that the one-way valve assembly 340 opens, and the strong airflow generated by the second fan 223, which has higher power, carries the dust in the storage fixtures 3121 and collects it in the dust collecting bin 222 in the dust collecting charging pile 200.

[0051] FIG. 9 is a structural schematic diagram of the one-way valve assembly in FIG. 7. In some embodiments, as shown in FIG. 9, the one-way valve assembly 340 includes a dust collecting air port 341, a valve member 342, and an elastic member 343.

[0052] The dust collection air port 341 is formed in the first side wall 3131 and is, for example, a rectangular opening. When the one-way valve assembly 340 is in a closed state, the valve member 342 abuts against an edge of the dust collection air port to close the dust collection air port 341, and when the one-way valve assembly 340 is in an open state, the valve member 342 separates from at least a portion of the edge of the dust collection air port 341 to allow airflow to enter the storage space 312 through the dust collection air port 341. The elastic member 343 is connected to the valve member 342 and configured to abut the valve member 342 at a sealing position of the dust collection air port 341.

[0053] Specifically, the valve member 342 includes a plate-like structure 3421 and a pivot part 3422 connected to the plate-like structure 3421. The plate-like structure 3421 is, for example, rectangular and slightly larger than the dust collection air port 341. When the one-way valve assembly 340 is in the closed state, the plate-like structure 3421 abuts against the edge of the dust collection air port 341 from the dust box space outward, thereby sealing the dust collection air port 341. When the one-way valve assembly 340 is switched from the closed state to the open state, the plate-like structure 3421 moves toward the inside of the dust box space and separates from at least a portion of the edge of the dust collection air port 341, allowing airflow to enter the dust box space through the dust collection air port 341. The pivot portion 3422 resembles a "T" shaped structure and is pivotally connected to the outer surface of the first side wall 3131, the pivot portion 3422 rotating relative to the first side wall 3131 about a pivot axis AX, which extends, for example, substantially perpendicular to the direction of the bottom wall 311, for example, the pivot portion 3422 can rotate in a plane substantially parallel to the bottom wall 311. An end of the pivot portion 3422 remote from the pivot axis AX is fixedly connected to said plate-like structure 3421, such that the valve member 342 rotates as a whole about the pivot axis AX.

[0054] An elastic member 343, for example a spring, is suitably connected to the pivot portion 3422 and, under the action of its elasticity, abuts the valve member 342 in a sealing position of the dust collecting air port.

[0055] 8 and 10 , a filter screen mounting opening 3151 is provided in the third side wall 315 of the box body, and the storage apparatus 300 further includes a filter screen assembly 330, which is detachably mounted in the filter screen mounting opening 3151 and faces the first fan 160 of the automatic cleaning device. The filter screen assembly 330 may have, for example, a substantially rectangular plate shape. When the automatic cleaning device 100 is in a cleaning operation mode, under the action of the airflow from the first fan 160, dust enters the frame 112 through the air vent 1121 and is collected in the dust box space 3121 of the automatic cleaning device 100. At the same time, gas is discharged through the filter screen assembly 330, and the dust is blocked in the dust box space by the filter screen assembly 330.

[0056] A water outlet assembly 350 is provided on the top wall 3133 of the recessed space and configured to discharge water stored in the water tank space from the storage appliance. As shown in Figure 10, the water outlet assembly includes a water outlet 351, a water discharge nozzle 352, and a sealing member (not shown). The water outlet 351 is opened on the top wall of the recessed space, and the water discharge nozzle 352 is attached to the water outlet and is used to supply water to the mop cloth of the automatic cleaning device. The sealing member is provided on the water outlet and is used to prevent water leakage from the water outlet.

[0057] A water extraction nozzle 360 ​​is further provided in the water tank space, and the water extraction nozzle 360 ​​is connected to the water outlet assembly 350 via a connecting pipe 370, and is used to extract water from the water tank space and transport it to the water outlet nozzle via the connecting pipe to supply water.

[0058] The top cover 320 is fitted to the box body 310 and configured to seal the top of the storage space 312. For example, the top cover 320 and the box body 310 may be designed separately, and may be pivotally connected via a side wall, allowing the storage device 300 to be switched between an open state and a closed state. In some embodiments, the top cover 320 and the box body 310 are non-detachably connected to improve the sealing of the box body 310.

[0059] 6, a water inlet 321 is provided on the top cover 320, and the orthogonal projection of the water tank space onto the top cover covers the water inlet 321. The storage device 300 further includes a water inlet plug 322 detachably attached to the water inlet 321 of the top cover to seal the water inlet. The water inlet plug is a switch for the water inlet 321, which opens when water needs to be poured and closes when the water is poured.

[0060] 11 is an exploded structural schematic diagram of a storage device provided according to some embodiments of the present disclosure. As shown in FIG. 11, the storage device further includes a water tank filter screen 323, which is detachably attached to the top cover on the side facing the box body and located at the water inlet, and the orthogonal projection of the water tank filter screen onto the top cover covers the water inlet. Here, the water tank filter screen 323 has a rectangular hollow structure. Water enters the water tank filter screen through the water inlet and is used to filter impurities in the injected water. The filtered water is stored in the water tank space and used when the mop cloth is in operation.

[0061] 6, the storage device further includes a one-way air valve port 324, which is opened in the top cover 320, and the orthogonal projection of the water tank space onto the top cover covers the one-way air valve port 324. The one-way air valve port 324 is used to install a one-way air valve and maintain the internal pressure of the water tank at atmospheric pressure when extracting water.

[0062] 1 to 11 , the storage device 300 is attached to the storage space 150 of the automatic cleaning device 100, and the first fan 160 of the automatic cleaning device 100 faces the filter screen assembly of the dust box space 3121, and airflow is extracted from the dust box space 3121 by the filter screen assembly. The air vent 1121 of the automatic cleaning device 100 communicates with the first opening 3141 of the dust box space 3121, and the air vent 1121 and the first opening 3141 form a passage for putting in and taking out dust from the automatic cleaning device 100.

[0063] When the automatic cleaning device is in cleaning operation mode, the first fan 160 operates to generate the external force applied to the one-way valve assembly, and when the external force is less than the threshold, the one-way valve assembly 60 is closed. Under the action of the suction force of the first fan 160, airflow passes sequentially through the vent, the second opening, the first opening, the dust box space, and the filter screen assembly to form a complete first duct. Specifically, the airflow carrying dirt enters the dust box space 3121 from the vent 1121 of the automatic cleaning device 100 through the first opening 3141 of the dust box space 3121, and after being filtered by the filter screen assembly, the dirt remains in the dust box space 3121, and the filtered airflow enters the automatic cleaning device and is discharged.

[0064] When the automatic cleaning device is in dust discharge mode, the automatic cleaning device 100 returns to the dust collecting charging pile 200, the dust suction port 211 of the dust collecting charging pile 200 functions as the inlet of the dust collecting air duct 215, and the dust suction port 211 of the dust collecting charging pile 200 is in sealed communication with the air vent 1121 of the automatic cleaning device 100 on the dust collecting charging pile base 210, i.e., the dust outlet of the automatic cleaning device 100. The air inlet of the dust collecting container 222 is in sealed communication with the outlet of the dust collecting air duct 215, and the second fan 223 is connected to the air outlet of the dust collecting container 222. In this mode, under the action of the airflow of the second fan 223 of the assembled charging pile 200, the external airflow passes sequentially through the air vent of the automatic cleaning device, the dust collecting air port, the dust box space, the first opening, the air vent, the dust suction port, and the dust collecting air duct to form a second duct.

[0065] Specifically, the second fan 223 in the dust collecting charging pile 200 operates to generate a strong suction force, and at the same time, the first fan 160 in the automatic cleaning device 100 also operates. When the first fan 160 and the second fan 223 are operating simultaneously, the external force acting on the one-way valve assembly 340 is greater than the threshold, causing the one-way valve assembly 340 to open. At this time, the dust collection air port 341 functions as an air inlet for the dust box space 3121, and most of the airflow carries the dust in the dust box space 3121 under the strong suction force of the second fan 223 with higher power. The airflow passes through the opening 3141 of the dust box space 3121, the ventilation port 1121 of the automatic cleaning device 100, the dust suction port 211 of the dust collection charging pile 200, and the dust collection air duct 215 into the dust collection container 222, and further collects the dust in the dust collection container 222. After the dust collection is completed, the first fan 160 and the second fan 223 stop operating. When the automatic cleaning device 100 is in dust discharge mode, if the first fan 160 in the automatic cleaning device 100 does not operate and only the second fan 223 in the dust collection charging pile 200 operates, the strong suction force of the second fan 223 will cause the external force acting on the one-way valve assembly 340 to be greater than the threshold, causing the one-way valve assembly 340 to open and ensuring that the entire airflow path is not blocked. However, because the airflow enters the dust box through the filter screen assembly 330, the airflow inlet opening becomes larger overall, and the airflow is not strong enough to blow up all the dust, affecting dust collection efficiency. Furthermore, the strong suction force of the second fan 223 may cause the first fan 160 to rotate backwards, potentially resulting in damage to the first fan 160.

[0066] In some embodiments, the operating power of the first fan 160 in the dust discharge mode of the automatic cleaning device 100 is equal to or less than the operating power of the first fan 160 in the cleaning operation mode of the automatic cleaning device 100. As long as it is possible to ensure that the first fan 160 is not damaged, it is better for the first fan 160 in the automatic cleaning device 100 to have a lower operating power in the dust discharge mode of the automatic cleaning device 100, thereby reducing the power consumption of the entire process of collecting dust from the dust box into the dust collection container.

[0067] Finally, in the storage tool and automatic cleaning device provided by the present disclosure, the dust box and water tank are integrated, so they move simultaneously when attached and detached, solving the problem of the conventional cleaning water tank and dust box having to be removed and loaded separately, which makes the operation complicated. The storage tool has the advantages of multiple functions, a small number of parts, low cost, easy assembly, and high space utilization. The storage tool is provided with a one-way valve assembly, which can be switched between a closed state and an open state to control the duct within the dust box space, and the dust within the dust box space can be discharged to the outside under the action of the fluid within the duct, thereby realizing the dust collection function.
