[Technical Field]

[0001] (Related Applications) This disclosure claims priority to Chinese Patent Application No. 202110719171.X, filed on June 28, 2021, the entire disclosure of which is incorporated herein by reference as part of this application.

[0002] The present disclosure relates to the technical field of automatic cleaning devices, and in particular to dust boxes, automatic cleaning devices and dust collection piles. [Background technology]

[0003] With the continuous development of technology, automatic cleaning devices such as sweeping robots have been widely adopted in homes. Sweeping robots can save time and labor compared to traditional manual cleaning, and only require users to clean the dust box inside the sweeping robot after cleaning. However, the dust box of a sweeping robot has a limited capacity and is located low, so users must frequently bend down to clean the dust box, which is bad for the users' health. Summary of the Invention

[0008] In some embodiments, the side wall further comprises a third side wall, an air outlet is opened in the third side wall, the air outlet is located on a side of the filtration mesh assembly away from the bottom wall, and the second side wall is located opposite the third side wall.

[0009] In some embodiments, the dust box further includes a dust box cover, the dust box cover being aligned with the dust box body and configured to seal the top of the storage space.

[0010] Some embodiments of the present disclosure provide an automatic cleaning device, the automatic cleaning device comprising: The automatic cleaning device includes a dust box as described in the above embodiment, a first blower connected to the air outlet and configured to discharge airflow from the storage space through the air outlet, and an air vent connected to the first through-hole and providing a passage for dust to enter or exit the automatic cleaning device.

[0013] In some embodiments, the dust collection pile is configured such that, in response to a dust discharge mode of the automatic cleaning device, the first blower and the second blower operate together to generate the external force applied to the one-way valve assembly, and the external force is greater than the threshold value.

[0014] In some embodiments, the operating power of the first fan in a dust discharge mode of the automatic cleaning device is equal to or less than the operating power of the first fan in a cleaning operation mode of the automatic cleaning device. [Effects of the Invention]

[0015] Compared with the related art, the above solution of the disclosed embodiment has at least the following beneficial effects:

[0016] The dust box with a one-way valve on its side wall can be used in an automatic cleaning device that collects dust inside the dust box into a dust collection pile. When the automatic cleaning device performs a cleaning operation, the one-way valve assembly of the dust box is closed, and a fan within the automatic cleaning device sucks dust and other debris into the dust box through the dust box's dust inlet and outlet, collecting the debris into 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 the debris inside the dust box into the dust collection pile, the fan within the dust collection pile operates, and under the suction force of the fan, the one-way valve assembly changes from the closed state to an open state. At this time, the one-way valve assembly forms an air inlet on the dust box, i.e., an air inlet for the entire airflow path, and the airflow transports the dust and other debris inside the dust box into the dust collection pile.

[0019] 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.

[0020] 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.

[0021] An automatic cleaning device typically includes a dust box for collecting debris. When the automatic cleaning device performs a cleaning job, debris in the work area, such as dust and paper scraps, is collected in the dust box. When a large amount of debris has accumulated in the dust box, a user removes the dust box from the automatic cleaning device, opens the dust box, and cleans out the debris. When cleaning out the debris in the dust box, a filter mesh assembly in the dust box typically needs to be removed and the debris cleaned out.

[0022] The present disclosure provides a dust box, for example, a dust box for an automatic cleaning device, for example, a sweeping robot. The dust box includes a dust box body having a bottom wall and a side wall extending around an edge of the bottom wall, the side wall extending away from the bottom wall, and the bottom wall and the side wall enclosing a storage space. The dust box also includes a dust box cover aligned with the dust box body and configured to close a top of the storage space, the side wall having a first through-hole that is a passage for dust to enter or exit the storage space. A one-way valve assembly is provided on the side wall of the dust box, the one-way valve assembly being maintained in a closed state and being switched from the closed state to an open state in response to an external force applied to the one-way valve assembly exceeding a threshold.

[0023] An automatic cleaning device using this dust box can be used in combination with a dust collection pile. When the automatic cleaning device is performing its cleaning task, the one-way valve assembly of the dust box is closed, and a fan within the automatic cleaning device, such as the first fan, sucks dust and other debris into the dust box through the dust box's dust inlet, such as the first through-hole, and collects the debris in the dust box as the automatic cleaning device performs its cleaning task. When the automatic cleaning device returns to the dust collection pile and connects to it, the fan within the dust collection pile, such as the second fan, operates, and the suction force of the second fan causes the one-way valve assembly to change from the closed state to an open state. At this time, the one-way valve assembly forms an air inlet on the dust box, i.e., an air inlet for the entire airflow path, and the airflow transfers the dust and other debris from the dust box into the dust collection pile.

[0024]

[0013] Optional embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. In the following embodiments, a dust collection pile will be explained and described using a dust collection pile as an example. The dust collection pile accumulates a large-volume dust collection container on the charging pile of a sweeping robot, and after the sweeping robot finishes cleaning, it is returned to the dust collection pile. The dust collection container installed on the dust collection pile collects dust from the dust box of the sweeping robot. When the dust collection container collects dust, the entrance / exit port of the sweeping robot needs to be connected to the dust suction port of the dust collection pile to prevent dust from leaking outside and causing secondary pollution. Those skilled in the art will understand that the solution disclosed herein can also be applied to a dust collection pile without a charging function.

[0025] 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.

[0026] 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 transfer the dust into the dust collection container.

[0027] 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 is not particularly limited to the number and installation positions of the charging electrodes.

[0028] 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, as the automatic cleaning device 100 moves over the support surface, e.g., a floor. In some embodiments, as shown in FIG. 2 , the cleaning module 110 is disposed between two drive wheels 130. The cleaning module 110 specifically includes a frame 112 and a roller brush 111 disposed within the frame 112, with a plurality of scraping strips 1111 disposed on the outer periphery of the roller brush 111. The frame 112 has a vent 1121 for exposing at least a portion of the roller brush 111.

[0029] When the automatic cleaning device 100 performs a cleaning operation, the roller brush 111 rotates, causing the scraping strips 1111 exposed by the frame 112 to come into contact with the floor surface, and at the same time, a fan within the automatic cleaning device 100, for example the first fan 160, generates an airflow that enters the frame 112 through the air vent 1121. Under the action of the scraping strips 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, i.e., the air vent 1121 functions as a dust suction port for the automatic cleaning device 100 when the automatic cleaning device 100 performs a cleaning operation.

[0030] The automatic cleaning device 100 further includes a dust box 150 and a first blower 160 installed therein. The dust box 150 is configured to collect debris such as dust when the automatic cleaning device 100 performs cleaning operations. The dust box 150 is in communication with the cleaning module 110. The first blower 160 is used to generate airflow as a power source for suction air when the automatic cleaning device 100 performs cleaning operations. When the automatic cleaning device 100 performs cleaning operations, the airflow from the first blower 160 causes debris to enter the frame 112 through the air vent 1121 and then be collected in the dust box 150 of the automatic cleaning device 100.

[0031] FIG. 3 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.

[0032] As shown in FIG. 3 , the dust-collecting charging pile 200 is composed of a dust-collecting charging pile base 210 and a dust-collecting charging body 220. The dust-collecting charging body 220 is configured to charge the automatic cleaning device 100 and collect dust in the dust box 150 of the automatic cleaning device 100, and is provided on the dust-collecting charging pile base 210. The dust-collecting charging body 220 includes a dust collection container 222 and a dust collection blower 223, also referred to as a second blower 223. The dust collection container 222 is, for example, cylindrical and is configured to collect dust in the dust box 150 of the automatic cleaning device 100. The second blower 223 is connected to an air outlet provided on the dust collection container 222 and provides power for collecting dust in the dust box 150 of the automatic cleaning device 100 into the dust collection container 222.

[0033] 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, 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), and dust in the dust box 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. 3 , 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. 3, a sealing rubber gasket 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.

[0034] 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 airflow action of the second blower 223, dust in the dust box 150 in the automatic cleaning device 100 can be collected into the dust collection container 222 from the air vent 1121 in the automatic cleaning device 100 through the dust collection air duct 215.

[0035] FIG. 4 is a schematic diagram of a scenario after an automatic cleaning device provided in some embodiments of the present disclosure is returned to the dust collecting charging pile. As shown in FIG. 4 , when the automatic cleaning device 100, such as a sweeping robot, finishes cleaning and returns to the dust collecting charging pile 200, the automatic cleaning device 100 moves along the first direction X to the dust collecting charging pile base 210, electrically connects the charging electrode 140 on the automatic cleaning device 100 to the charging connector 221, charges 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 collecting charging pile 200, and transfers the garbage in the dust box of the automatic cleaning device 100 to the dust collection container 222 of the dust collecting charging pile 200.

[0036] FIG. 5 is a structural schematic diagram of a dust box provided by some embodiments of the present disclosure, FIG. 6 is a structural schematic diagram of the dust box body of the dust box in FIG. 5, and FIG. 7 is a structural schematic diagram of the dust box in FIG. 5 from another perspective. As shown in FIGS. 5 to 7, the dust box 150 includes a dust box body 10. The dust box body 10 has a bottom wall 15 and side walls arranged around the edges of the bottom wall 10, and the side walls extend away from the bottom wall 15, and the bottom wall 15 and the side walls surround and form the storage space 30. As shown in FIGS. 5 to 7, the number of side walls is, for example, four, and the dust box 150 is generally rectangular.

[0037] In some embodiments, the dust box includes a dust box cover 20 that is aligned with the dust box body 10 and closes the top of the storage space 30, for example, the dust box cover 20 is pivotally connected to one side wall of the dust box body 10, and the dust box 150 is configured to be switched between an open state and a closed state.

[0038] The dust box body 10 is generally rectangular, and its orthogonal projection onto a plane on which the bottom wall 15 is located is generally rectangular. The side walls of the dust box body 10 include two short side walls and two long side walls. In this specification, the short side walls refer to the side walls corresponding to the short sides of the rectangular projection of the rectangle. Accordingly, in this specification, the long side walls refer to the side walls corresponding to the long sides of the rectangular projection of the rectangle. The dust box cover 20 rotates around an axis relative to one of the short side walls of the dust box body 10, making it easier for users to remove dirt from the dust box 150, clean or replace the filter mesh structure, etc.

[0039] In some embodiments, the dust box 150 is in a closed state when the dust box cover 20 completely closes the top of the storage space 30 and is engaged with the dust box body 10 by a snap mechanism. The dust box 150 is in an open state when the dust box cover 20 rotates to expose at least a portion of the storage space 30. The dust box 150 can be switched between a closed state and an open state, allowing users to easily perform operations such as removing dust from the dust box 150, cleaning or replacing the filter mesh structure, etc.

[0040] A first through-hole 41 is formed in the first side wall 11 of the dust box body 10, and the first through-hole is a passage for dust to enter or exit the storage space 30. A one-way valve assembly 60 is provided on the second side wall 12 of the dust box 150. The first side wall 11 is, for example, one long side wall of the dust box body 10, and the second side wall 12 is, for example, one short side wall of the dust box body 10. The one-way valve assembly 60 is maintained in a closed state, and is converted from the closed state to an open state in response to an external force applied to the one-way valve assembly 60 exceeding a threshold. The external force is, for example, a suction force generated when the first fan 160 of the automatic cleaning device 100 or the second fan 223 of the dust collection charging pile 200 is activated. The threshold value is a critical value of the external force required to change the one-way valve assembly 60 from a closed state to an open state.

[0041] 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 collection charging pile 200. That is, 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 60 is closed. Under the action of the airflow from the first fan 160, dust enters the frame 112 through the vent 1121 and is then collected in the dust box 150 of the automatic cleaning device 100. When the automatic cleaning device 100 is returned to the dust collecting charging pile 200 and connected to the dust collecting charging pile 200 to collect the dust in the dust box 150 into the dust collecting container 222 in the dust collecting charging pile 200, specifically, the automatic cleaning device 100 moves along 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 60 changes from the closed state to the open state. At this time, the one-way valve assembly forms an air inlet on the dust box 150, i.e., an air inlet for the entire airflow, and the dust and other debris in the dust box 150 are transferred by the airflow into the dust collecting container 222 in the dust collecting charging pile 200.

[0042] In some embodiments, when the automatic cleaning device 100 is placed on the dust collection charging pile base 210 of the dust collection charging pile 200 and collects dust in the dust box 150 into the dust collection container 222 in the dust collection charging pile 200, i.e., when the automatic cleaning device 100 is in dust discharge mode, the second fan 223 operates to generate strong suction force, and the first fan 160 in the automatic cleaning device 100 also operates. This prevents the first fan 160 in the automatic cleaning device 100 from rotating backward due to the strong suction force generated by the second fan, which could result in damage to the first fan 160. At this time, the first fan and the second fan are both operating, and the external force applied to the one-way valve assembly is greater than the threshold, so the one-way valve assembly 60 opens, and the strong airflow generated by the second fan 223 with high power carries the dust in the dust box 150 and collects it in the dust collection container 222 in the dust collection charging pile 200.

[0043] FIG. 8 is a structural schematic diagram of the one-way valve assembly in FIG. 5, and in some embodiments, as shown in FIG. 8, the one-way valve assembly 60 includes a second through-hole 61, a valve member 62 and an elastic member 63.

[0044] The second through-hole 61 is formed in the second side wall 12 and is, for example, a rectangular opening. The valve member 62 is configured such that, in response to the closed state of the one-way valve assembly 60, the valve member 62 abuts against the edge of the second through-hole 62 to close the second through-hole 62, and in response to the open state of the one-way valve assembly 60, the valve member 62 separates from at least a portion of the edge of the second through-hole 61 to allow airflow to enter the accommodating space 30 through the second through-hole 61.

[0045] An elastic member 63 is connected to the valve member 62 and holds the valve member 62 in a position that closes the second through-hole 61 .

[0046] Specifically, the valve member 62 includes a plate-like structure 621 and a pivot portion 622 connected to the plate-like structure 621. The plate-like structure 622 is, for example, rectangular and slightly larger than the second through-hole 61. When the one-way valve assembly 60 is in a closed state, the dust box 150 presses tightly against the edge of the second through-hole 61 from the inside to the outside, sealing the second through-hole 61. When the one-way valve assembly 60 is changed from a closed state to an open state, the plate-like structure 621 moves toward the inside of the dust box 150 and separates from at least a portion of the edge of the second through-hole 61, allowing airflow to enter the accommodating space 30 through the second through-hole 61. The pivot portion 622 has a "T"-like structure and is pivotally connected to the outer surface of the second side wall 12, and the pivot portion 622 rotates relative to the second side wall 12 about a pivot axis AX, which extends, for example, substantially perpendicular to the direction of the bottom wall 15, so that the pivot portion 622 rotates in a plane substantially parallel to the bottom wall 15. An end of the pivot portion 622 remote from the pivot axis AX is fixedly connected to the plate-like structure 621, and the entire valve member 62 rotates about the pivot axis AX.

[0047] The elastic member 63 is, for example, a spring, which is fitted and connected to the pivot portion 622 and holds the valve member 62 in a position where it closes the second through-hole 61 under its elastic action.

[0048] 5 to 7, in some embodiments, the dust box 150 further includes a filter mesh assembly 50, which is removably disposed within the accommodating space 30. The filter mesh assembly 50 is, for example, in the form of a generally rectangular plate. A stepped structure is provided on the inner wall of the side wall of the dust box body 10 to support the filter mesh assembly 50. The accommodating space 30 is divided by the filter mesh assembly 50 into a first accommodating space 31 and a second accommodating space 32, which are disposed on either side of the filter mesh assembly 50. Specifically, the first storage space 31 is located closer to the bottom wall 15 of the filter mesh assembly 50, and the second storage space 32 is located further away from the bottom wall 15 of the filter mesh assembly 50. The first storage space 31 is used to store dust collected by the dust box 150, and the second storage space 32 functions as part of the air passage after the airflow passes through the filter mesh assembly 50, ensuring smooth circulation of the airflow.

[0049] In some embodiments, the first through-hole 41 and the second through-hole 61 are both located between the filter mesh assembly 50 and the bottom wall 15. Specifically, the orthogonal projection of the first accommodating space 31 on the first side wall 11 covers the first through-hole 41, and the orthogonal projection of the first accommodating space 31 on the second side wall 12 covers the second through-hole 61. The first through-hole 41 and the second through-hole 61 allow the first accommodating space 31 to communicate with the outside of the dust box 150.

[0050] 5 to 7, the air outlet 43 is provided on the third side wall 13 of the dust box 150, which may be, for example, another short side wall of the dust box 150, facing the second side wall 12. The air outlet 43 is provided on the side away from the bottom wall 15 of the filter mesh assembly 50. An orthogonal projection of the second storage space 32 on the third side wall 13 covers the air outlet 43.

[0051] 1 to 7, the first fan 160 of the automatic cleaning device 100 is connected to the air outlet 43 of the dust box 150 and draws air from the storage space 30 through the air outlet 43. The air vent 1121 of the automatic cleaning device 100 communicates with the first through-hole 41 of the dust box 150, and the air vent 1121 is a passage through which dust enters the automatic cleaning device 100 or exits the automatic cleaning device 100.

[0052] When the automatic cleaning device is in cleaning operation mode, the first blower 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 suction force of the first blower 160, the airflow carrying dirt enters the first storage space 31 through the air vent 1121 of the automatic cleaning device 100 and the first through-hole 41 of the dust box 150. After being filtered by the filter mesh assembly, the dirt remains in the first storage space 31, and the filtered airflow enters the second storage space 32 and is extracted from the dust box 150 through the air outlet 43 under the suction force of the first blower 160.

[0053] As shown in FIGS. 1 to 7 , after the automatic cleaning device 100, for example a sweeping robot, finishes cleaning and returns to the dust collecting charging pile 200, the automatic cleaning device 100 moves along the first direction X to the dust collecting charging pile base 210, the charging electrode 140 on the automatic cleaning device 100 is electrically connected to the charging connector 221 to charge the automatic cleaning device 100, and the dust discharge port, i.e., the ventilation port 1121, of the automatic cleaning device 100 is connected to the dust suction port 211 of the dust collecting charging pile 200, and in this case, the dust in the dust box of the automatic cleaning device 100 is transferred to the dust collection container 222 of the dust collecting charging pile 200. At this time, when the automatic cleaning device 100 is in dust discharge mode, the dust suction port 211 of the dust collecting charging pile 200 serves 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 discharge port 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. Under the action of the airflow from the second fan 223, dust in the dust box 150 of the automatic cleaning device 100 is collected from the air vent 1121 of the automatic cleaning device 100 through the dust collecting air duct 215 and into the dust collecting container 222.

[0054] The automatic cleaning device 100 is placed on the dust collection charging pile base 210 of the dust collection charging pile 200, and collects the garbage in the dust box 150 into the dust collection container 222 in the dust collection charging pile 200. In other words, when the automatic cleaning device 100 is in dust discharge mode, the second fan 223 in the dust collection charging pile 200 operates to generate a strong suction force, and the first fan 160 in the automatic cleaning device 100 also operates. When the first fan 160 and the second fan 223 are both operating, the external force applied to the one-way valve assembly 60 is greater than the threshold, causing the one-way valve assembly 60 to open. At this time, the second through-hole 62 functions as an air inlet for the dust box 150, and most of the airflow carries the dust inside the dust box 150 under the strong suction force of the high-power second fan 223. The airflow then passes through the first through-hole 41 of the dust box 150, the air vent 1121 of the automatic cleaning device 100, the dust suction port 211 of the dust collecting charging pile 200, and the dust collecting air passage 215 into the dust collecting container 222, where the dust is further collected. When the automatic cleaning device 100 is in dust discharge mode, the first fan 160 in the automatic cleaning device 100 does not operate, and only the second fan 223 in the dust collecting charging pile 200 operates. In this case, the external force applied to the one-way valve assembly 60 due to the strong suction force of the second fan 223 is still greater than the threshold, and the one-way valve assembly 60 is in an open state, ensuring that the entire air flow path is not blocked. However, the first fan 160 may reverse under the action of the strong suction force of the second fan 223, which may lead to damage to the first fan 160.

[0055] 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.
