In the present disclosure, when no dust bag is attached to the dust bag support, the sliding baffle is in, for example, a first position, blocking the dust outlet port, sealing off the dust within the dust collection passage, and preventing the dust from entering the dust collection bin without the dust bag attached.
[0030] Selected embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.
[0031] FIG. 1 is a structural schematic diagram of an automatic cleaning device provided according to 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.
[0032] 1 and 2, the automatic cleaning device 100, e.g., a sweeping robot, includes a universal wheel 120 and a drive wheel 130, which allow the automatic cleaning device 100 to move on a supporting surface such as the ground. Optionally, the automatic cleaning device 100 moves along a predetermined path, and may return to the dust collection pile to recharge, unload the dust into the dust collection pile, clean and dry the mopping assembly, etc., under certain circumstances, such as when the automatic cleaning device 100 is running out of power, when the dust collection box of the automatic cleaning device 100 is full of debris, or when the automatic cleaning device 100 has completed sweeping, mopping, etc.
[0033] The automatic cleaning device 100 further includes charging electrodes 140 electrically connected to the dust collection pile to charge the automatic cleaning device 100 after the automatic cleaning device 100 returns to the dust collection 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 140 is, for example, two, one on each side of the universal 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 specifically limit the number and installation positions of the charging electrodes 140.
[0034] The automatic cleaning device 100 further includes a cleaning module 110, such as a dry cleaning module. The cleaning module 110 is configured to clean at least a portion of a support surface, such as the ground, when the automatic cleaning device 100 moves over the support 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 includes a rolling brush cover 112 and a rolling brush 111 disposed within the rolling brush cover 112. A cleaning member 1111 is disposed on the outer periphery of the rolling brush 111, and may be a bristle brush, a rubber brush, or a bristle-rubber brush. The rolling brush cover 112 is provided with an air vent 1121, which exposes at least a portion of the rolling brush 111.
[0035] When the automatic cleaning device 100 performs cleaning operations, the rolling brush 111 rotates, and the cleaning element 1111 exposed by the rolling brush cover 112 can come into contact with the ground. At the same time, the fan in the automatic cleaning device 100 generates an air current that enters the rolling brush cover 112 through the air vent 1121. Under the action of the cleaning element 1111 and the air current, dust passes through the air vent 1121 into the rolling brush cover 112 and is then collected in the dust box of the automatic cleaning device 100. The air vent 1121 also serves as a dust circulation port. That is, when the automatic cleaning device 100 performs cleaning operations, the air vent 1121 functions as a dust suction port of the automatic cleaning device 100. When collecting dust, the air vent 1121 is used as a dust outlet of the automatic cleaning device 100, and the dust in the dust box is discharged through the air vent 1121 into the dust collection container of the dust collection pile. 3 is a structural schematic diagram of a dust collecting pile provided according to some embodiments of the present disclosure. As shown in FIG. 3, the dust collecting pile 200 is configured to supply energy to the automatic cleaning device 100 and collect dust.

[0037] 3 and 4, the dust collection pile 200 further includes a fan assembly 230. The fan assembly 230 is disposed in the fan cavity and is used to provide suction for the dust collection operation of the dust collection pile. The fan assembly 230 includes a fan 231 and a sound-deadening cotton sleeve 232. The fan 231 includes a motor portion 2311 and an air suction portion 2312 adjacent to the motor portion 2311 and driven by the motor portion 2311. The air suction portion 2312 includes, for example, blades configured to rotate under the drive of the motor portion 2311 to generate an airflow. The fan 231 is configured to generate an airflow in an operating state to collect dust into the dust collection bin 222 through the dust inlet 211. The sound-deadening cotton sleeve 232 is configured to be sleeved around the outer periphery of the motor portion 2311, thereby reducing the operating noise of the fan itself when the fan is operating, and reducing the noise when the dust collection pile 200 performs dust collection operations.
[0038] 5 is a structural schematic diagram of a fan lower housing provided according to some embodiments of the present disclosure. In some embodiments, as shown in FIGS. 4 and 5 , the fan assembly 230 further includes a first housing 233 and a second housing 234. The first housing 233 may be, for example, the fan lower housing (hereinafter referred to as the fan lower housing 233), and has a fan mounting position 2331 configured to accommodate the motor portion 2311, into which the sound-absorbing cotton sleeve 232 is fitted. The second housing 234 may be, for example, the fan upper housing (hereinafter referred to as the fan upper housing 234), and is configured to accommodate the air suction portion 2312 of the fan 231, aligned with the fan mounting position 2331. The fan upper housing 234 may be fixedly connected to the fan mounting position 2331 of the fan lower housing 233 by a connecting member such as a screw. When the two are fitted together, an accommodation space for accommodating the fan 231 is formed. The fan 231 is fastened and accommodated within the accommodation space to prevent displacement within the accommodation space.
[0039] 4, a first opening 2341 is provided in the second housing 234 and is configured to align with the air inlet of the fan 231, and the first opening 2341 is provided with a lattice structure. This prevents an operator from accidentally inserting a finger into the first opening 2341 of the second housing 234 and causing injury by the finger coming into contact with the blades of the air inlet of the fan 231, thereby eliminating a potential safety hazard, and at the same time, prevents large particles of dust from entering the air suction portion 2312 through the first opening 2341 and damaging the fan, e.g., the blades.
[0040] 3 to 5 , the first housing 233 further includes an air outlet channel 2332, which is disposed adjacent to the fan mounting position 2331 and communicates with the interior space of the fan mounting position 2331 through a hole on the side wall of the fan mounting position 2331. The air outlet channel 2332 is configured to guide the airflow generated by the fan 231 to flow out of the dust collecting pile main body 220. The air outlet channel 2332 includes an outlet 23322 disposed at an end of the air outlet channel 2332 and aligned with the air outlet 2211 on the side wall of the fan cavity 221 of the dust collecting pile main body 220. An airflow sound-absorbing structure is disposed on the inner wall of the air outlet channel 2332 and is disposed on the outflow passage of the airflow to reduce noise generated when the airflow passes through the air outlet channel 2332.
[0041] In some embodiments, the airflow sound-absorbing structure includes a plurality of spaced-apart partitions 23321 extending from the inner wall of the air outlet channel in a direction opposite to the air outlet direction within the air outlet channel, as indicated by the arrow in FIG. 5 , and the partitions are inclined relative to the inner wall of the air outlet channel in which they are located. Specifically, the plurality of spaced-apart partitions 23321 are provided on two opposing inner walls of the air outlet channel, and the spaced-apart partitions are uniformly or non-uniformly arranged and extend essentially along the same direction, i.e., the partitions on the same inner wall are parallel to each other. The partitions on the two opposing inner walls of the air outlet channel form a sawtooth-shaped airflow sound-absorbing structure, which can reduce noise generated when airflow passes through the air outlet channel 2332. The partition plate 23321 is provided at an angle to the inner wall of the air outlet channel in which it is located, and the angle with the inner wall of the air outlet channel in which it is located is, for example, 30° to 50°, and specifically, may be, for example, 45°.
[0042] In other embodiments, the divider may be located on only one interior wall of the air outlet channel, or the divider may be located on the bottom wall of the air outlet channel.
[0043] In some embodiments, the airflow sound-absorbing structure may have a plurality of openings formed in the side walls of the air outlet channel 2332, and sound-absorbing material may be placed in the corresponding openings in the outer wall of the air outlet channel 2332, or sound-absorbing material may be placed directly on the inner wall of the air outlet channel 2332.
[0044] FIG. 6 is an exploded structural view of a fan assembly provided by some embodiments of the present disclosure. As shown in FIGS. 3 to 6, a through hole 2333 is provided in the bottom wall of the first housing 233, through which the power cable of the fan 231 passes. The dust collecting pile 200 may further include a rubber plug 2334 for a wire harness configured to fit tightly against the through hole 2333, and the rubber plug 2334 for a wire harness has a through hole configured to allow the power cable and / or signal line of the fan 231 to pass through. By inserting the rubber plug 233 for the wire harness tightly into the through hole 2333 and making it tightly fit against the through hole 2333, the gap between the through hole 2333 and the power cable of the fan 231 passing through it can be reduced, preventing air leakage at the through hole 2333 in the first housing 233 and preventing water vapor, dust, etc. from entering the control board area of the dust collection pile 200 through the through hole 2333 on the bottom wall of the first housing 233 and damaging the precision electronic components on the control board.
[0045] In some embodiments, the dust collecting pile 200 further includes a dust barrel support 240 configured to divide the dust collecting pile body 220 into the fan cavity 221 and the dust collection bin 222, and a receiving portion 241 is provided on a bottom wall of the dust barrel support facing the fan assembly 230 and configured to receive a portion of the second housing 234, the receiving portion 241 being used to position the fan assembly 230.

[0046] 7 is an assembly schematic diagram of a fan assembly and a dust barrel support 240 provided according to some embodiments of the present disclosure. In some embodiments, as shown in FIGS. 3 to 7 , the second housing 234 is provided with a first opening 2341 configured to align with the air inlet of the fan 231, and the bottom wall of the dust barrel support is provided with a second opening 242 configured to expose the first opening 2341. That is, the second opening is also aligned with the air inlet of the fan 231. The air inlet of the fan 231 draws gas from the dust collection bin 222 through the first opening 2341 of the second housing 234 and the second opening 242 on the bottom wall of the dust barrel support 240 to form an airflow, creating a negative pressure in the dust collection bin 222. Dust is sucked into the dust collection bin 222 through the dust inlet 211 in the dust collection pile 210 by the dust collection pipe and then collected in, for example, a dust collection bag in the dust collection bin 222.
[0047] In some embodiments, the dust collection pile 200 further includes a protective cover 260 that is detachably fitted to the second opening 242, for example, by engaging with the second opening 242 on the side of the bottom wall of the dust barrel support that is away from the fan assembly. The protective cover 260 is engaged with the second opening 242 in the bottom wall of the dust barrel support, for example, by engaging with the second opening 242, which facilitates attachment and detachment of the protective cover 260. The protective cover 260 has a lattice-like hollow structure that does not affect the flow of air when fitted to the second opening 242. The installation of the protective cover 260 prevents dust in the dust collection bin 222 from entering the air inlet of the fan 231, while also protecting users from accidentally inserting their fingers into the air inlet of the fan 231 and injuring them due to the high-speed rotation of the blades.
[0048] In some embodiments, the first housing 233 is fitted onto the bottom wall of the dust barrel support 240, and the two are sealed and connected to prevent air leakage, so that the fan 231 arranged on the first housing 233 can provide a strong suction force to the dust collection bin 222, creating negative pressure in the dust collection bin 222.
[0049] FIG. 8 is a structural schematic diagram of a dust bag support provided by some embodiments of the present disclosure, with the sliding baffle in a first position, and FIG. 9 is a structural schematic diagram of a dust bag support provided by some embodiments of the present disclosure, with the sliding baffle in a second position.

A dust outlet port 272 is provided in a side wall 271 of the dust bag support 270, which communicates with the dust inlet 211 through a dust collection passageway, which is used to guide dust into the dust collection bin, for example, to a dust bag in the dust collection bin. The dust outlet port 272 is configured to communicate with the dust bag to collect the dust into the dust bag.
[0051] The dust bag support 270 further includes a sliding baffle 273 slidable on the side wall 271. The sliding baffle 273 is switchable between a first position and a second position. When the sliding baffle 273 is in the first position, the sliding baffle 273 covers the dust outlet port 272. When the sliding baffle 273 is in the second position, the sliding baffle 273 exposes the dust outlet port 272. Since the dust bag is a consumable item, it is detachably attached to the dust bag support 270. With the above design, when no dust bag is attached to the dust bag support 270, the sliding baffle covers the dust outlet port, isolating the dust collection bin from the dust collection passage, sealing off dust in the dust collection passage, and preventing dust from entering the dust collection bin 222 without a dust bag attached.
[0052] Figure 10 is a structural schematic diagram of a dust bag provided according to some embodiments of the present disclosure, with the sliding plate in a third position, and Figure 11 is a structural schematic diagram of a dust bag provided according to some embodiments of the present disclosure, with the sliding plate in a fourth position.

When the sliding plate 283 is in the fourth position, as shown in Fig. 11, the orthographic projection of the sliding plate opening 2831 on the locking plate 282 overlaps with at least a portion of the locking plate opening 2821, and the sliding plate 283 exposes at least a portion of the locking plate opening 2821 through the sliding plate opening 2831. In some embodiments, the size of the sliding plate opening 2831 is larger than, for example, the locking plate opening 2821, such that, in response to the sliding plate 283 being in the third position, an orthographic projection of the sliding plate opening 2831 on the locking plate 282 covers the locking plate opening 2821. In some embodiments, the size of the sliding plate opening 2831 is smaller than, for example, the locking plate opening 2821, such that, in response to the sliding plate 283 being in the third position, an orthographic projection of the sliding plate opening 2831 on the locking plate 282 is located at the locking plate opening 2821. In some embodiments, the size of the sliding plate opening 2831 is equal to, for example, the locking plate opening 2821, such that, in response to the sliding plate 283 being in the third position, an orthographic projection of the sliding plate opening 2831 on the locking plate 282 overlaps with the locking plate opening 2821.
[0055] The dust bag 280 is detachably mounted on the dust bag support 270, and in response to the dust bag 280 being mounted on the dust bag support 270, the sliding baffle 273 is in the second position, the sliding plate is in the fourth position, and the locking plate opening 2821 is aligned with the dust outlet port 272. With the above-mentioned installation, when no dust bag is attached to the dust bag support, the sliding baffle 273 is in the first position, covering the dust outlet port 272 and sealing off the dust in the dust collection passage, preventing the dust from entering a dust collection bin to which no dust bag is attached. When a dust bag is not attached to the dust bag support, its sliding plate 283 covers the locking plate opening 2821 of the locking plate 282, and when the dust bag support is attached, the sliding plate 283 and the locking plate 282 work together to push the sliding baffle 273 from the first position to the second position and fix it in the second position, and when the dust bag support is pulled away, the sliding plate covers the locking plate opening to prevent dust leakage. After the dust bag is attached to the dust bag support, the locking plate opening, i.e., the dust bag inlet, is aligned with the dust outlet port, and under the action of the fan airflow, dust in the dust box of the automatic cleaning device passes through the dust inlet on the dust collecting pile base, the dust collecting passage in the dust collecting pile, the dust outlet port on the dust bag support and the locking plate opening on the dust bag, successively, and is collected in the dust bag body.
[0056] 12 is a schematic diagram of a pre-assembled dust bag support and a dust bag provided according to some embodiments of the present disclosure, and FIG. 13 is a schematic diagram of an assembled structure of the dust bag support and a dust bag provided according to some embodiments of the present disclosure. In some embodiments, as shown in FIGS. 8 to 13, the dust bag support 270 includes a sliding groove 274, at least a portion of the sliding baffle 273 is located in the sliding groove 274, the sliding baffle 273 is slidable along the extension direction X of the sliding groove 274, and is switchable between a first position and a second position. The number of sliding grooves 274 may be, for example, one or more. As shown in Figures 8 to 13, the number of sliding grooves 274 is, for example, two, and they are provided at opposite ends of the side wall 271 of the dust bag support body 270, respectively. The two sliding grooves 274 respectively accommodate two opposite ends of the sliding baffle 273, and the sliding baffle 273 can slide along the extension direction X of the sliding grooves 274.
[0057] 8 to 13, the locking plate 282 and the sliding plate 283 of the dust bag 280 are inserted into the sliding groove 274 and slide along the extending direction X of the sliding groove 274, thereby attaching the dust bag 280 to the dust bag support body 270. Specifically, both ends of the locking plate 282 and the sliding plate 283 of the dust bag 280 can be inserted into the two sliding grooves 274, respectively.
[0058] As shown in FIG. 12 , in the process of attaching the dust bag 280 to the dust bag support 270, the dust bag 280 moves relative to the dust bag support 270 along the extension direction X of the sliding groove 274. When the two are attached, the locking plate 282 and the sliding plate 283 of the dust bag 280 face the side wall 271 of the dust bag support 270. When the locking plate 282 and the sliding plate 283 are inserted into the sliding groove 274 along the extension direction X of the sliding groove 274, they push the sliding baffle 273 to move from the first position to the second position. FIG. 13 is a cross-sectional view of an assembly structure of a dust bag support and a dust bag provided according to some embodiments of the present disclosure. As shown in FIGS. 8 to 13 , a locking portion 2741, such as an elastic snap, is provided in the sliding groove 274, and the locking plate 282 is provided with a locking groove 2821 that fits the locking portion 2741. In response to the locking plate 282 sliding along the extension direction X of the sliding groove 274 to a locking position, the locking plate opening 2821 is aligned with the dust outlet port 272, and the locking portion 2741 is fitted into and locked in the locking groove 2822, thereby fixing the dust bag 280 to the dust bag support 270.
[0059] 8 to 13, one end of the sliding plate 283 is provided with a handle portion 2832 configured to allow an operator to grip and move the sliding plate 283. The sliding plate further includes unlock bump blocks 2833, which are provided, for example, at both ends of the sliding plate 283 and configured to press the locking portion 2741 to disengage the locking portion 2741 from the locking groove 2822 during the process of pulling the sliding plate 283 away from the locking groove 274, thereby releasing the locking plate from the locking portion 2741 and allowing the dust bag to be smoothly detached from the dust bag support body.
[0060] In some embodiments, as shown in Figures 8-13, the unlocking bump block 2833 also has a limiting effect, cooperating with a limiting member 2823 on the locking plate 282 to prevent the sliding plate 283 from disengaging from the locking plate 282.
[0061] In some embodiments, the dust bag support 270 may be provided with an elastic member, such as a spring, connected to the sliding baffle 273 to bias the sliding baffle 273 to the first position. When the sliding baffle 273 is not subjected to an external force, under the action of the elastic member, the sliding baffle 273 is in the first position and blocks the dust outlet port 272.
[0062] The following is a detailed description of the process of attaching and detaching the dust bag 280 to the dust bag support 270. When the dust bag 280 is not attached to the dust bag support 270, the sliding baffle 273 on the dust bag support 270 is in the first position to block the dust outlet port 272, and the sliding plate 283 on the dust bag 280 is in the third position to block the locking plate opening 282, i.e., as shown in FIG. When the dust bag 280 is attached to the dust bag support 270, the locking plate 282 and the sliding plate 283 are inserted into the sliding groove 274 along the extension direction X of the sliding groove 274. When a user holds the handle 2832 of the sliding plate 283 to push the dust bag 280 into the sliding groove 274, the sliding plate 283 gradually moves from the third position to the fourth position relative to the locking plate 282, and the sliding plate opening 2831 on the sliding plate 283 is aligned with the locking plate opening 2821 on the locking plate 282. At the same time, the locking plate 282 and the sliding plate 283 push the sliding baffle 273 to move from the first position to the second position, so that the sliding baffle 273 is exposed from the dust outlet port 272. When the locking plate 282 slides along the extension direction X of the sliding groove 274 to the locking position, the locking plate opening 2821 is aligned with the dust outlet port 272, the locking portion 2741 fits into the locking groove 2822 and is locked, and the dust bag 280 is fixed on the dust bag support 270.
[0063] In the process of attaching or detaching the dust bag 280 to or from the dust bag support 270, the operator grasps the handle 2832 of the sliding plate 283 and gradually pulls the sliding plate 283 away from the sliding groove 274 of the dust bag support 270. In this process, the sliding plate 283 gradually moves from the fourth position to the third position relative to the locking plate 282, so that the sliding plate 283 covers the locking plate opening 2821, and the unlocking bump block 2833 on the sliding plate 283 presses the locking portion 2741 to move the locking portion 2741 into the locking groove 274. 822, the handle portion 2832 of the sliding plate 283 is continuously pulled to pull the sliding plate 283 and the locking plate 282 out of the sliding groove 274 of the dust bag support 270 due to the interaction between the unlock bump block 2833 and the limiting member 2823 of the locking plate 282, so that the dust bag 280 is released from the dust bag support 270, and the sliding baffle 273 returns to the first position under the action of the elastic member, and the sliding baffle 273 covers the dust outlet port 272.
[0064] 14 is a structural schematic diagram of a lifting cover provided according to some embodiments of the present disclosure, and FIG. 15 is an assembly schematic diagram of a lifting cover and a dust barrel support provided according to some examples of the present disclosure. As shown in FIGS. 1-15, in some embodiments, the dust collection pile 200 further includes a dust barrel support 240 and a lifting cover 290.
[0065] As described above, the dust barrel support 240 is configured to divide the dust collection pile body 220 into the fan cavity 221 and the dust collection bin 222, and the lifting cover 290 is configured to fit over the dust barrel support 240 to form the dust collection bin 222. In some embodiments, as shown in Figure 14, a sealing strip is provided on the inner wall of the lifting cover 290, and the lifting cover 290 is configured to fit over the dust barrel support 240 to form a sealed dust collection bin 222.
[0066] The dust collection pile further includes a position detection device, which is mounted on at least one of the dust barrel support 240 and the lifting cover 290 and is configured to detect the alignment of the lifting cover 290 and the dust barrel support 240. The position detection device may be a Hall detector, a photoelectric detector, or the like, and is used to send an alarm when it detects that the lifting cover 290 and the dust barrel support 240 are not aligned to a predetermined position, informing the user that the lifting cover 290 and the dust barrel support 240 are not aligned properly and that there is a risk of air leakage. The position detection device may be, for example, a Hall detector, which includes a Hall detector (also known as a Hall sensor) and a magnet, which are mounted on the lifting cover 290 and the dust barrel support 240, respectively. When the lifting cover 290 and the dust barrel support 240 are fully aligned, the Hall detector outputs an electrical signal, e.g., a voltage value above a predetermined threshold, indicating that the lifting cover 290 and the dust barrel support 240 are aligned properly. If the lifting cover 290 and the dust barrel support 240 are not aligned to the predetermined position, the electrical signal output from the Hall detector, for example, a voltage value, is smaller than a predetermined threshold, indicating that the lifting cover 290 and the dust barrel support 240 are not aligned properly.
[0067] In some embodiments, a position detection device is provided on at least one of the dust bag support 270 and the lift-up cover 290 to detect whether the lift-up cover 290 is installed in a predetermined position, which will not be repeated here.
[0068] In some embodiments, a through-hole is provided in the bottom wall of the dust barrel support 240, i.e., the second opening 242 in the embodiments is configured to connect the fan cavity and the dust collection bin, and the dust collection pile further includes a protective cover 260, which is detachably engaged with the through-hole to prevent debris in the dust collection bin from entering the fan cavity.
[0069] 7, as described above, the lift-up cover 290 forms a sealed dust collection bin 222 when fitted to the dust barrel support 240, with the bottom wall of the dust barrel support 240 functioning as the bottom wall of the dust collection bin 222 and the side walls of the dust barrel support 240 functioning as part of the side walls of the dust collection bin 222. The dust collection pile 200 further includes support ribs 2221, which may be provided on the inner walls of the dust collection bin 222, as shown in FIG. 7, for example, on the bottom wall and / or side walls of the dust collection bin 222. This arrangement prevents the dust bag from sticking tightly to the inner walls of the dust collection bin and blocking the airflow.
[0070] 7, the dust collecting pile 200 further includes a pressure relief valve 2222, which is disposed in the dust collecting bin 222 and configured to adjust the air pressure in the dust collecting bin to prevent the air pressure in the dust collecting bin from becoming too low. When the dust collecting pile 200 performs dust collection operation, the fan directs airflow to create a negative pressure in the dust collecting bin. When the air pressure in the dust collecting bin is lower than a preset threshold, the pressure relief valve is activated to connect the dust collecting bin to the external environment, thereby allowing the dust collecting pile 200 to operate normally.
[0071] In some embodiments, when the dust bag 280 is mounted on the dust bag support 270, if the sliding baffle 273 is in the second position, the fan 231 can be activated normally and the entire system operates normally. When the dust bag 280 is filled to a certain extent, the airflow in the entire system becomes less smooth and the air pressure in the dust collection bin 222 becomes lower and lower. When it reaches a certain level, the pressure relief valve opens to balance the unbalanced air pressure. In some embodiments, in response to the activation of the pressure relief valve, the fan stops operating to protect the fan and remind the user to clean the dust bag.
[0072] In some embodiments, when the dust bag 280 is not attached to the dust bag support 270, the sliding baffle is in the first position, blocking communication between the dust collection passage and the dust collection bin 222. In such a case, the fan is controlled not to start, preventing the fan from operating when the dust bag is not attached. In other embodiments, when the dust bag 280 is attached to the dust bag support 270, the fan can start normally, and at this time, the dust collection bin 222 is isolated from the dust collection passage by the sliding baffle 273, and the suction force generated by the fan acts only within the dust collection bin 222. When the pressure within the dust collection bin 222 reaches a critical value for activating the pressure relief valve and the fan continues to operate, the pressure relief valve is activated to release the pressure and balance the pressure within the dust collection bin 222.
[0073] In some embodiments, the pressure relief valve may be replaced by a pressure sensor, which is controlled to stop the fan operation or perform a pressure relief operation on the dust collection bin 222 if an abnormal pressure is detected.
[0074] In some embodiments, the fan's dust collection time may be constant or may be determined according to control conditions. When the automatic cleaning device automatically returns to the pile to collect dust, the fan's operation time may be set to, for example, 10 to 15 seconds. When a user manually presses the dust collection button on the pile or manually starts dust collection via the APP, the time may be set to, for example, 20 to 30 seconds. In some embodiments, when the device automatically returns to the pile to collect dust, the dust collection time may be determined according to the device's operation time, or, for example, the dust collection time may be determined by a dust volume sensor in the device's dust box.
[0075] In some embodiments, if the position detection device detects that the lift-up cover 290 and the dust barrel support 240 are not locked or attached, the fan is controlled to a non-operating state to prevent the fan from starting in such a case.
[0076] The automatic cleaning system provided by some embodiments of the present disclosure includes a dust collection pile 200 in the embodiments and an automatic cleaning device 100 in the embodiments. The automatic cleaning device includes, for example, a dust box and a dust outlet. When the automatic cleaning device 100 finishes a cleaning operation and returns to the dust collection pile 200 to perform a dust collection operation, the dust outlet of the automatic cleaning device 100 is abutted against the dust inlet 211 on the top surface of the dust collection pile base 210, and the fan 231 in the dust collection pile is activated, so that dust in the dust box of the automatic cleaning device 100 passes through the dust inlet 211 and is collected into a dust collection bag or a dust separation mechanism of the dust collection bin 222, which may be, for example, a cyclone dust classifier.
[0077] Finally, it should be noted that the embodiments in this specification will be described step by step, each embodiment will focus on the differences from other embodiments, and the same or similar parts between the embodiments may be referred to. The systems or devices disclosed in the embodiments will be briefly described in correspondence with the methods disclosed in the embodiments, and the relevant parts may be referred to in the description of the method parts.
