[0014] Selective embodiments of this disclosure will be described in detail below with reference to the attached drawings.

[0015] In related technologies, the dustbins of automatic cleaning devices have limited capacity, often requiring users to bend down to clean them, resulting in a poor user experience. Therefore, embodiments of this disclosure provide a self-cleaning dust collection sheet, which uses a dust collection system to concentrate the debris in the dustbin of the automatic cleaning device and collect it in the dust collection bin of the self-cleaning dust collection sheet, thereby reducing the number of times users have to dispose of the debris and improving the user experience. Specifically, as an example of the self-cleaning dust collection sheet provided by embodiments of this disclosure, Figure 1 is a schematic diagram illustrating the overall structure of the self-cleaning dust collection sheet, and Figure 2 is a schematic diagram showing the structure of the self-cleaning dust collection sheet body after the wastewater tank, clean water tank, and dust collection cover of this disclosure have been removed.

[0016] To more clearly explain the behavior of the self-cleaning dust collection sheet, the following directions are defined. Specifically, the self-cleaning dust collection sheet is defined by three mutually perpendicular axes: the lateral axis Y, the front-to-back axis X, and the central vertical axis Z. The direction opposite to the arrow along the front-to-back axis X, i.e., the direction in which the automatic cleaning device enters the self-cleaning dust collection sheet, is defined as "rear," and the direction of the arrow along the front-to-back axis X, i.e., the direction in which the automatic cleaning device leaves the self-cleaning dust collection sheet, is defined as "front." The lateral axis Y is essentially the direction along the width of the self-cleaning dust collection sheet body. The vertical axis Z is the direction extending upward along the bottom surface of the self-cleaning dust collection sheet.

[0017] As shown in Figure 1, the self-cleaning dust collection sheet bottom plate 1000 protrudes from the self-cleaning dust collection sheet body 2000 in the forward direction, the direction toward the rear wall of the self-cleaning dust collection sheet body 2000 is the rear direction, the dust collection bin 3000 is on the left side of the self-cleaning dust collection sheet, the clean water tank 4000 is on the right side of the dust collection bin 3000, and the wastewater tank 5000 is on the right side of the clean water tank 4000.

[0018] As shown in Figure 1, the self-cleaning dust collection sheet provided by this embodiment includes a self-cleaning dust collection sheet base plate 1000 and a self-cleaning dust collection sheet body 2000. Here, the self-cleaning dust collection sheet base plate 1000 is detachably connected to the self-cleaning dust collection sheet body 2000, specifically, the self-cleaning dust collection sheet base plate 1000 is detachably connected to a body base 6000 at the bottom of the self-cleaning dust collection sheet body 2000. The detachable connection method facilitates transportation and maintenance.

[0019] The self-cleaning dust collection sheet body 2000 is configured to collect debris in the dust box of the automatic cleaning device. In some embodiments, the self-cleaning dust collection sheet body 2000 is further provided with components such as a dust collection bin 3000, a clean water tank 4000, and a wastewater tank 5000.

[0020] As shown in Figure 2, the self-cleaning dust collection sheet body 2000 includes a water storage chamber 2700 and a dust collection chamber 2100. The water storage chamber 2700 opens upward and forward and is located at the top of the self-cleaning dust collection sheet body 2000. The water storage chamber may further include a clean water bottle for housing a clean water tank 4000 and a dirty water bottle for housing a dirty water tank 5000. The dust collection chamber 2100 opens upward and forward and is located at the top of the self-cleaning dust collection sheet body 2000, alongside the water storage chamber 2700. A dust collection cover 2800 is provided on the dust collection chamber 2100 to fit the opening of the dust collection chamber 2100. The dust collection cover 2800 is detachably engaged on the dust collection chamber 2100, and together with the dust collection cover 2800, the dust collection chamber 2100 forms a dust collection bottle 3000 for housing a waste collection device. At least a portion of the outer surface of the dust collection cover 2800 functions as part of the outer surface of the self-cleaning dust collection sheet. The water storage chamber 2700 and the dust collection chamber 2100 are designed to face upward and forward, which facilitates the attachment and detachment of the wastewater tank 5000, the clean water tank 4000, and the dust collection cover 2800.

[0021] A main body base 6000 is located below the self-cleaning dust collection sheet main body 2000. In some embodiments, the main body base 6000 is integrally provided below the self-cleaning dust collection sheet main body 2000. The main body base 6000 is further in contact with the self-cleaning dust collection sheet bottom plate 1000, specifically, the self-cleaning dust collection sheet bottom plate 1000 and the main body base 6000 are provided sequentially along a second direction, which is opposite to the direction of the arrow on the front-rear axis X.

[0022] The dust collection port 6100 is provided on the main body base 6000, and is located approximately at the edge of the connection point between the main body base 6000 and the self-cleaning dust collection sheet bottom plate 1000. The dust collection port 6100 is configured to be connected to the dust outlet of the automatic cleaning device, and debris in the dust box 300 of the automatic cleaning device enters the dust collection chamber 2100 of the self-cleaning dust collection sheet main body 2000 through the dust collection port 6100. In some embodiments, a sealing rubber gasket is further provided around the dust collection port 6100, and the sealing rubber gasket is used to seal the abutted dust collection port 6100 and the dust outlet of the automatic cleaning device to prevent debris leakage.

[0023] In some embodiments, the main body base 6000 further includes a cleaning groove 6200, which is configured to clean cleaning members on the automatic cleaning device, for example, to replenish cleaning fluid in the wet cleaning module of the automatic cleaning device and / or to collect debris removed from the wet cleaning module and / or to collect wastewater generated during the cleaning process of the wet cleaning module, thereby facilitating subsequent processing of debris and wastewater. In some embodiments, the cleaning groove 6200 is located behind the dust collection port 6100.

[0024] In some embodiments, the self-cleaning dust collection sheet further includes an air duct, one end of which communicates with a dust collection port 6100 of the main body base 6000, and the other end of which communicates with a dust collection chamber 2100. When the self-cleaning dust collection sheet is in the dust collection state, sufficient negative pressure is formed in the dust collection bin 3000, and the dust in the dust box 300 is sucked into the dust bag in the dust collection chamber 2100 via the dust collection port 6100 and the air duct.

[0025] Referring together to Figures 2 and 3, in some embodiments, the dust collection chamber 2100 includes a rear dust collection chamber wall 2134 and a pair of opposing dust collection chamber side walls, the dust collection chamber side walls further including a first dust collection chamber side wall 2131 and a second dust collection chamber side wall 2132, the first dust collection chamber side wall 2131 is adjacent to the outer wall of the self-cleaning dust collection sheet body 2000, the first dust collection chamber side wall 2131 is provided opposite to the second dust collection chamber side wall 2132, and both the first dust collection chamber side wall 2131 and the second dust collection chamber side wall 2132 are adjacent to the rear dust collection chamber wall 2134.

[0026] Specifically, the end face of the dust collection chamber side wall may have an arc-shaped structure, the height of the dust collection chamber side wall tends to gradually decrease along the direction of the arrow on the front-rear axis X, and at the adjacent part between the dust collection chamber side wall and the dust collection chamber rear wall 2134, the height of the dust collection chamber side wall is equal to the height of the dust collection chamber rear wall 2134. The dust collection chamber side wall adopts an arc-shaped structure that is lower at the front and higher at the rear, which facilitates the attachment and detachment of the dust collection cover 2800 and improves the aesthetic appearance to some extent.

[0027] In some embodiments, the first dust collection chamber side wall 2131, the second dust collection chamber side wall 2132, and the dust collection chamber rear wall 2134 are integrally structured with the self-cleaning dust collection sheet body 2000, thereby improving the stability of the dust collection chamber 2100 and preventing the dust collection chamber 2100 from shaking relative to the self-cleaning dust collection sheet body 2000.

[0028] In some embodiments, the dust collection chamber 2100 further includes a circumferential inner wall 2150, which extends from the bottom wall of the dust collection chamber 2100 toward the self-cleaning dust collection sheet body 2000. The rear wall 2134 and side walls of the dust collection chamber are provided around the circumferential inner wall 2150, spaced apart from it. The heights of all parts of the circumferential inner wall 2150 may differ, and in some embodiments, the height of the circumferential inner wall 2150 tends to gradually decrease along the direction of the arrow on the front-rear axis X, and such a structural design of the circumferential inner wall 2150, with the front side lower and the rear side higher, facilitates the attachment and detachment of the dust collection cover 2800.

Furthermore, each inner wall of the circumferential inner wall 2150 corresponds to the rear wall 2134 of the dust collection chamber and the side walls of the dust collection chamber. Specifically, the first side inner wall 2151 and the first dust collection chamber side wall 2131 are on the same side and spaced apart, the rear inner wall 2154 and the rear wall 2134 of the dust collection chamber are on the same side and spaced apart, and the second side inner wall 2152 and the second dust collection chamber side wall 2132 are on the same side and spaced apart.

[0030] In some embodiments, the circumferential inner wall 2150 and the bottom wall of the self-collecting dust chamber 2100 are integrally structured, which can improve the stability of the circumferential inner wall 2150.

[0031] In some embodiments, the dust collection chamber 2100 may further include a sealing pad 2140, which is provided around the circumferential inner wall 2150, and the rear wall 2134 and side walls of the dust collection chamber are provided around the sealing pad 2140. In some embodiments, the sealing pad 2140 has a closed-loop structure, and the width of all parts of the sealing pad 2140 may be equal to or slightly greater than the spacing between the circumferential inner wall 2150 and the rear wall 2134 and side walls of the dust collection chamber, so that the sealing pad 2140 is in close contact with the circumferential inner wall 2150, the rear wall 2134 and side walls of the dust collection chamber. The material of the sealing pad 2140 may be various natural or synthetic rubbers. The sealing pad 2140 allows the dust collection chamber 2100 and the dust collection cover 2800 fitted over the dust collection chamber 2100 to be tightly and closely fitted together, forming a sealed dust collection bin 3000.

[0032] In some embodiments, a dust bag bracket 2110 is further provided within the dust collection chamber 2100, and the dust bag bracket 2110 is configured to attach a dust bag. The dust bag bracket 2110 is provided inside the dust collection chamber 2100 and extends from the bottom of the dust collection chamber toward away from the self-cleaning dust collection sheet body 2000. The dust bag bracket 2110 may be provided on the circumferential inner wall 2150 of the dust collection chamber 2100 by fastening members such as screws, or it may be fixed to the bottom wall of the dust collection chamber via the bottom of the dust bag bracket 2110. In some embodiments, the dust bag bracket 2110 is provided on the first side inner wall 2151, and the side wall of the dust bag bracket 2110 toward the dust collection chamber 2100 may be integrally formed with the first side inner wall 2151, which can improve the stability of the dust bag bracket 2110. The dust bag bracket 2110 has a hollow cavity inside which functions as part of the air duct of the self-cleaning dust collection sheet, for example, as the tail end of the air duct. The dust bag bracket 2110 has a bracket side wall facing the inside of the dust collection bin 3000, and a dust outlet is provided in the bracket side wall. The dust outlet communicates with the dust collection port 6100 via an air duct, and the air duct is configured to guide the debris into the dust collection bin 3000, for example, into the dust bag inside the dust collection bin 3000.

By providing support ribs 2826, it is possible to prevent the dust bag in the dust collection bin 3000 from sticking to the dust collection chamber bottom wall, the circumferential inner wall 2150, and / or the dust collection cover wall 2820, thereby avoiding adverse effects on airflow outflow from the dust bag due to sticking.

[0039] This disclosure further provides an automatic cleaning device and a dust collection system comprising a self-cleaning dust collection sheet as in the above embodiment.

[0040] The design of the dust collection cover, which flips and aligns within the dust collection chamber, ensures that the dust collection cover is more tightly coupled to the chamber under the action of the fan, further improving dust collection efficiency. The exposed design of the dust collection cover also makes it easier for the user to intuitively observe the situation inside the cover, and makes it easier to handle the dust collection chamber in a timely manner, such as changing the dust bag.

[0041] In related technologies, the dust box of an automatic cleaning device has a limited capacity, often requiring users to bend down to clean it, resulting in a poor user experience. Therefore, an embodiment of this disclosure provides a self-cleaning dust collection sheet, in which a dust collection system concentrates the debris in the automatic cleaning device's dust box and collects it in the dust collection bin of the self-cleaning dust collection sheet. By providing a dust bag bracket and a dust bag inside the dust collection bin, the debris in the dust box is transferred to the dust bag in the dust collection bin without leakage, reducing the number of times the user has to handle the debris and improving the user experience. The dust bag employs a cooperative design of an engaging plate and a sliding plate, so that when the dust bag is removed from the dust bag bracket, the sliding plate is in a closed position, preventing debris from remaining in the dust collection bin.

[0042] Specifically, regarding the self-cleaning dust collection sheet provided by the embodiments of this disclosure, as an example, Figure 1 is a schematic diagram illustrating the overall structure of the self-cleaning dust collection sheet, and Figure 2 is a schematic diagram illustrating the structure of the self-cleaning dust collection sheet body after the wastewater tank, clean water tank, and dust collection cover of this disclosure have been removed.

[0047] In some embodiments, the main body base 6000 further includes a cleaning groove 6200, which is configured to clean cleaning members on the automatic cleaning device, for example, to replenish cleaning fluid in the wet cleaning module of the automatic cleaning device and / or to collect debris removed from the wet cleaning module and / or to collect wastewater generated during the cleaning process of the wet cleaning module, thereby facilitating subsequent processing of debris and wastewater. In some embodiments, the cleaning groove 6200 is located behind the dust collection port 6100.

[0048] In some embodiments, the self-cleaning dust collection sheet further includes an air duct, one end of which communicates with a dust collection port 6100 of the main body base 6000, and the other end of which communicates with a dust collection chamber 2100. When the self-cleaning dust collection sheet is in the dust collection state, sufficient negative pressure is formed inside the dust collection bin 3000, drawing the dust from the dust box 300 through the dust collection port 6100 and the air duct into the dust bag in the dust collection chamber 2100.

[0049] Figure 6 is a schematic diagram showing the structure of a dust bag bracket provided by some embodiments of the present disclosure, with the sliding baffle in a first position, and Figure 7 is a schematic diagram showing the structure of a dust bag bracket provided by some embodiments of the present disclosure, with the sliding baffle in a second position.

[0050] As shown in Figures 1 and 2, in some embodiments, the self-cleaning dust collection sheet further includes a dust bag bracket 2110, which is configured to attach a dust bag. The dust bag bracket 2110 is provided inside the dust collection bin 3000 and may be attached to the inner wall of the dust collection bin 3000 by fastening members such as screws, or it may be fixed to the bottom surface of the dust collection bin 3000 via the bottom of the dust bag bracket 2110.

[0051] The dust bag bracket 2110 has a hollow cavity inside, which functions as part of the air duct of the self-cleaning dust collection sheet, for example, as the tail end of the air duct.

[0052] The dust bag bracket 2110 has a bracket side wall 2111 facing the inside of the dust collection bin 3000, and a dust outlet 2112 is provided on the bracket side wall 2111. The dust outlet 2112 communicates with the dust collection port 6100 via an air duct, and the air duct is configured to guide the debris into the dust collection bin 3000, for example, into the dust bag inside the dust collection bin 3000. The dust outlet 2112 is configured to communicate with the entrance of the dust bag in order to collect the debris into the dust bag.

[0053] The dust bag bracket 2110 further includes a sliding baffle 2113 that is slidable on the bracket side wall 2111. The sliding baffle 2113 is configured to switch between a first position and a second position. In response to the sliding baffle 2113 being in the first position, the sliding baffle 2113 shields the dust outlet 2112, and in response to the sliding baffle 2113 being in the second position, the sliding baffle 2113 exposes the dust outlet 2112. Since the dust bag is a consumable item, it is detachably attached to the dust bag bracket 2110. By adopting the above design, the dust bag bracket 2110, when not attached to the dust bag, can block the dust outlet 2112 with the sliding baffle 2113, isolating the dust collection bin 3000 from the air duct. As a result, the suction force generated by the fan does not enter the air duct from the dust collection bin, thus preventing dust from entering the dust collection bin 3000 when the dust bag is not attached.

[0054] Figure 8 is a schematic diagram showing the structure of a dust bag provided by some embodiments of the present disclosure, with the sliding plate in the closed position; Figure 9 is a schematic diagram showing the structure of a dust bag provided by some embodiments of the present disclosure, with the sliding plate in the open position; Figure 9A is a schematic diagram showing a partial structure of a dust bag provided by some embodiments of the present disclosure; Figure 9B is a schematic diagram showing the cross-sectional structure in Figure 9A; Figure 9A shows a cross-section of the dust bag; and Figures 9 and 9B do not show the dust bag.

[0055] In some embodiments, as shown in Figures 8 to 9B, the present disclosure further provides a dust bag 2120 which is detachably attached to a dust bag bracket 2110 and configured to collect waste.

[0056] The dust bag 2120 includes a dust bag body 2121, an engagement plate 2122, and a sliding plate 2123. The dust bag body 2121 is made from a material that is breathable but can filter fine particles, such as a nonwoven fabric or paper material, and is configured to contain the waste. The engagement plate 2122 is fixedly connected to the dust bag body 2121. The engagement plate 2122 has an engagement plate opening 21221, which functions as an entrance to the dust bag body 2121. The sliding plate 2123 is slidably connected to the engaging plate 2122 and is configured to switch between a closed position and an open position. In response to the sliding plate 2123 being in the closed position, the sliding plate 2123 shields the engaging plate opening 21221, and in response to the sliding plate 2123 being in the open position, the sliding plate 2123 exposes the engaging plate opening 21221.

[0057] Specifically, as shown in Figures 8 and 6, the sliding plate 2123 has a sliding plate opening 21231. In response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 onto the engaging plate 2122 does not overlap with the engaging plate opening 2821, and the sliding plate 2123 shields the engaging plate opening 22121, as shown in Figure 8. In response to the sliding plate 2123 being in the open position, the orthographic projection of the sliding plate opening 21231 onto the engaging plate 2122 at least partially overlaps with the engaging plate opening 21221, and the sliding plate 2123 exposes at least a portion of the engaging plate opening 21221 through the sliding plate opening 21231, as shown in Figure 9.

[0058] In some embodiments, the size of the sliding plate opening 21231 is larger than, for example, the engagement plate opening 21221, and in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 onto the engagement plate 2122 covers the engagement plate opening 21221. In some embodiments, the size of the sliding plate opening 21231 is smaller than, for example, the engagement plate opening 21221, and in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 onto the engagement plate 2122 falls into the engagement plate opening 21221. In some embodiments, the size of the sliding plate opening 21231 is equal to, for example, the engagement plate opening 21221, and in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 onto the engagement plate 2122 substantially overlaps the engagement plate opening 21221.

[0059] The sliding cooperation between the sliding plate 2123 and the engaging plate 2122 closes the opening of the dust bag, preventing waste from leaking out of the dust bag.

[0060] In some embodiments, as shown in Figures 8 to 9B, a flexible rubber ring 21224 is provided on the edge of the engagement plate opening 21221, projecting toward the sliding plate 2123. In response to the sliding plate 2123 being in the open position, the flexible rubber ring 21224 passes through the sliding plate opening 21231 and projects toward the sliding plate 2123, sealing the gap created by the abutment of the two openings of the sliding plate 2123 and the engagement plate 21221 when the sliding plate opening 21231 and the engagement plate opening 21221 are brought into contact, thereby achieving a sealed connection between the sliding plate opening 21231 and the engagement plate opening 21221. In response to the sliding plate 2123 being in a position other than the open position, for example, the closed position, at least a portion of the flexible rubber ring 21224 is pressed between the sliding plate 2123 and the engaging plate 2122, increasing the frictional force between them. Unless a certain external force is applied, the sliding plate 2123 and the engaging plate 2122 cannot slide relative to each other, the sliding plate 2123 is stably held in the closed position, and the dispersion of dust in the dust bag can be prevented.

[0061] In some embodiments, as shown in Figures 8 and 9, the sliding plate 2123 is slidable relative to the engaging plate 2122 in a first direction M, and the sliding plate 2123 includes limiting projections 21243 provided on at least one side of the sliding plate 2123, for example on both sides of the sliding plate 2123, the number of limiting projections 21243 being, for example, two, and projecting from the sliding plate 2123 in a second direction perpendicular to the first direction M. The engaging plate 2122 includes limiting members 21223 provided at both ends of the engaging plate 2122 in the first direction, and configured to stop the limiting projections 21233 in the first direction M, thereby preventing the sliding plate 2123 from detaching from the engaging plate 2122. The number of limiting members 21223 being, for example, four, is distributed symmetrically on both sides of the engaging plate 2122. When the sliding plate 2123 slides against the engaging plate 2122, the limiting projection 21233 can only move between the corresponding limiting members 21223 at both ends of the engaging plate 2122 in the first direction.

[0062] In some embodiments, the sliding plate 2123 further includes a handle portion 21232 provided at one end of the sliding plate in a first direction M and configured to facilitate the operator's grip for moving the sliding plate 2123.

[0063] The dust bag 2120 is detachably mounted on the dust bag bracket 2110. In response to the dust bag 2120 being mounted on the dust bag bracket 2110, the sliding baffle 2123 is in a second position, exposing the dust outlet. In response to the sliding plate being in an open position, the engagement plate opening 21221 is connected to the dust outlet 2112. With this setup, when the dust bag bracket 2110 is not mounted on the dust bag 2120, the sliding baffle 2113 is in a first position, shielding the dust outlet 2112. This prevents the suction force generated by the fan from entering the air duct from the dust collection bin, thus preventing dust from entering the dust collection bin 3000 when the dust bag 2120 is not mounted.

[0064] When the dust bag 2120 is removed from the dust bag bracket 2110, the sliding plate is in the closed position 2123, preventing the dust in the dust bag from dispersing into the dust collection bin. Because it is a sealed dust bag, it is possible to prevent the dust in the dust bag from being dispersed into the external environment.

[0065] When the dust bag 2120 is not attached to the dust bag bracket 2110, the sliding plate 2123 shields the engagement plate opening 21221 of the engagement plate 2122. When the dust bag 2120 is attached to the dust bag bracket 2110, the combined action of the sliding plate 2123 and the engagement plate 2122 pushes the sliding baffle 2113 from the first position to the second position and fixes it in that second position. When the dust bag 2120 is removed from the dust bag bracket 2110, the sliding plate 2123 shields the engagement plate opening 21221, preventing dust leakage. After the dust bag bracket 2110 is attached to the dust bag 2120, the engagement plate opening 21221 (i.e., the dust bag inlet) is connected to the dust outlet 2112, and under the action of the airflow provided by the fan, the debris in the dust box of the automatic cleaning device is sequentially collected into the dust bag body 2121 through the dust collection port 6100 on the main body base 6000, the air duct in the self-cleaning dust collection sheet, the dust outlet 2112 on the dust bag bracket 2110, and the engagement plate opening 21221 on the dust bag 2120.

[0066] Figure 10 is a schematic diagram of a pre-assembled dust bag bracket and dust bag provided by some embodiments of the present disclosure, and Figure 11 is a schematic diagram showing the assembled structure of the dust bag bracket and dust bag provided by some embodiments of the present disclosure.

[0067] In some embodiments, as shown in Figures 6 to 11, the dust bag bracket 2110 includes a sliding groove 2114, at least a portion of the sliding baffle 2113 is located within the sliding groove 2114, the sliding baffle 2113 is slidable along the extension direction X' of the sliding groove 2114, and is further switchable between a first position and a second position. The number of sliding grooves 2114 may be one or more, for example, as shown in Figures 6 to 11, for example, there may be two sliding grooves 2114, each provided at opposing ends of the bracket side wall 2111 of the dust bag bracket 2110, the two sliding grooves 2114 each accommodating the opposing ends of the sliding baffle 2113, and configured so that the sliding baffle 2113 can slide along the extension direction X' of the sliding groove 2114.

[0068] As shown in Figures 6 to 11, the engaging plate 2122 and sliding plate 2123 of the dust bag 2120 are inserted into the sliding groove 2114 and slide along the extending direction X' of the sliding groove 2114, pushing the sliding baffle 2113 to slide along the extending direction X' of the sliding groove, thereby attaching the dust bag 2120 to the dust bag bracket 2110. Specifically, both ends of the engaging plate 2122 and sliding plate 2123 of the dust bag 2120 can be inserted into the two sliding grooves 2114 described above. In response to the dust bag 2120 being attached to the dust bag bracket 2110, the sliding plate 2123 is in the open position, exposing the engagement plate opening 21221, the sliding baffle 2113 is in the second position, exposing the dust outlet 2112, and the engagement plate opening 21221 and the dust outlet 2112 are brought into contact.

[0069] As shown in Figure 10, during the process of attaching the dust bag 2120 to the dust bag bracket 2110, the dust bag 2120 moves relative to the dust bag bracket 2110 along the extending direction X' of the sliding groove 2114. When attaching the two, the engaging plate 2122 and sliding plate 2123 of the dust bag 2120 face the bracket side wall 2111 of the dust bag bracket 2110, and in the process of inserting the engaging plate 2122 and sliding plate 2123 into the sliding groove 2114 along the extending direction X' of the sliding groove 2114, the sliding baffle 2113 is pushed to move from the first position to the second position.

[0070] In some embodiments, a sliding baffle projection 21131 is provided at the lower end of the sliding baffle 2113, and the sliding baffle projection 21131 is a band-shaped projection that runs along the lower edge of the sliding baffle 2113 toward the dust collection bin 3000. After the sliding plate 2123 is inserted into the sliding groove 2114, the lower end of the sliding plate 2123 comes into contact with the sliding baffle projection 21131. The lower ends of the sliding plate 2123 and the sliding baffle projection 21131, which are in contact with each other, push the sliding baffle 2113 and slide together along the extending direction X' of the sliding groove when the sliding plate 2123 slides downward along the extending direction X' of the sliding groove. In some embodiments, a sliding plate projection 21233 is also provided at the lower end of the sliding plate 2123, and this sliding plate projection 21233 is a band-shaped projection that runs along the lower edge of the sliding plate 2123 toward the dust collection bin 3000. After the sliding plate 2123 is inserted into the sliding groove 2114, the sliding plate projection 21233 abuts directly above the sliding baffle projection 21131. The mutually abutting sliding plate projection 21233 and the sliding baffle projection 21131 push the sliding baffle 2113 and slide together along the extending direction X' of the sliding groove when the sliding plate 2123 slides downward along the extending direction X' of the sliding groove.

[0071] Figure 11 shows a cross-sectional view of the dust bag bracket and dust bag assembly structure provided by some embodiments of the present disclosure, and Figure 12 is a schematic diagram showing the dust bag bracket and dust bag assembly structure provided by some embodiments of the present disclosure.

[0072] As shown in Figures 11 and 12, a buckle portion 21141, for example, an elastic buckle, is provided in the sliding groove 2114 and can move in a substantially arc shape as shown by the arrow in Figure 27. The engaging plate 2122 includes an engaging groove 21222 that fits the buckle portion 21141, and in response to the dust bag 2120 being attached to the dust bag bracket 2110, the buckle portion 21141 engages with the engaging groove 21222. The engaging plate 2122 slides along the extending direction X' of the sliding groove 2114 to the engaging position, the engaging plate opening 21221 abuts against the dust outlet 2112, the buckle portion 21141 is clamped in correspondence with the engaging groove 21222, and the dust bag 2120 is fixed on the dust bag bracket 2110.

[0073] The restricting projection 212234 on the sliding plate 2123 also functions as a release projection 21234, also called the release projection 21234, and in the process of separating the sliding plate 2123 from the sliding groove 2114, it presses the buckle portion 21141, disengaging the buckle portion 21141 from the engagement groove 21222, releasing the fixation of the engagement plate 2122 by the buckle portion 21141, and allowing the dust bag 2120 to be smoothly detached from the dust bag bracket 2110. In some embodiments, the release projection 21234 further has a restricting function and cooperates with a restricting member 21223 on the engagement plate 2122 to prevent the sliding plate 2123 from disengaging from the engagement plate 2122.

[0074] In some embodiments, as shown in Figure 13, an elastic member 2115, such as a spring, is provided in the dust bag bracket 2110. The elastic member 2115 is connected to the sliding baffle 2113 and configured to allow the sliding baffle 2113 to tend to be in a first position. When the sliding baffle 2113 is not subjected to external force, under the action of the elastic member 2115, the sliding baffle 2113 is in the first position and the sliding baffle 2113 blocks the dust outlet 2112. In some embodiments, the elastic member 2115 is located inside the dust bag bracket 2110, the extension direction of the elastic member 2115 substantially coincides with the extension direction of the sliding groove 2114, one end of the elastic member 2115 is fixed to the top of the dust bag bracket 2110 and the other end is connected to the sliding baffle 2113. The number of elastic members 2115 may be one or more. For example, if there are two elastic members 2115, they may be provided at opposite ends of the dust bag bracket 2110.

[0075] The following describes in detail the process of attaching and detaching the dust bag 2120 and the dust bag bracket 2110.

[0076] When the dust bag bracket 2110 is not attached to the dust bag 2120, the sliding baffle 2113 of the dust bag bracket 2110 is in the first position, blocking the dust outlet 2112, and the sliding plate 2123 on the dust bag 2120 is in the closed position, blocking the engagement plate opening 2122, i.e., the state shown in Figure 8. In the process of attaching the dust bag 2120 to the dust bag bracket 2110, the engaging plate 2122 and the sliding plate 2123 are inserted into the sliding groove 2114 along the extending direction X' of the sliding groove 2114. In the process of the user grasping the handle portion 21232 of the sliding plate 2123 and pushing the dust bag 2120 into the sliding groove 2114, the sliding plate 2123 gradually moves from a closed position to an open position relative to the engaging plate 2122, the sliding plate opening 21231 on the sliding plate 2123 and the engaging plate opening 21221 on the engaging plate 2122 align, and at the same time the engaging plate 2122 and the sliding plate 2123 push the sliding baffle 2113, moving it from a first position to a second position, exposing the sliding baffle 2113 from the dust outlet 2112. When the engagement plate 2122 slides along the extension direction X' of the sliding groove 2114 to the engagement position, the engagement plate opening 21221 is connected to the dust outlet 2112, the buckle portion 21141 is clamped corresponding to the engagement groove 21222, and the dust bag 2120 is fixed on the dust bag bracket 2110. At this time, the flexible rubber ring 21224 on the dust bag passes through the sliding plate opening 21231 and comes into contact with the edge of the dust outlet 2112, achieving sealing and abutting between the engagement plate opening 21221 of the dust bag and the dust outlet 2112 of the dust bag bracket, thereby preventing dust leakage during the dust collection process.

[0077] In the process of removing the dust bag 2120 from the dust bag bracket 2110, the operator can grasp the handle portion 21232 of the sliding plate 2123 and gradually separate the sliding plate 2123 from the sliding groove 2114 of the dust bag bracket 2110. In this process, the sliding plate 2123 moves from an open position to a closed position relative to the engaging plate 2122, the sliding plate 2123 blocks the engaging plate opening 21221, and the lock release projection 21234 on the sliding plate 2123 presses against the buckle portion 21141. The sliding plate 2123 is disengaged from the engagement groove 21222, and simultaneously, the interaction between the unlock projection 21234 and the limiting member 21223 on the engagement plate 2122 causes the handle portion 21232 of the sliding plate 2123 to be continuously pulled out, disengaging the sliding plate 2123 and the engagement plate 2122 from the sliding groove 2114 of the dust bag bracket 2110, disengaging the dust bag 2120 from the dust bag bracket 2110, and the sliding baffle 2113 returns to its first position under the action of the elastic member, causing the sliding baffle 2113 to block the dust outlet 2112.

[0078] This disclosure further provides an automatic cleaning device and a dust collection system comprising a self-cleaning dust collection sheet as in the above embodiment.

[0079] In the self-cleaning dust collection sheet provided by the embodiments of this disclosure, the dust collection system concentrates the waste in the dust box of the automatic cleaning device and collects it in the dust collection bin of the self-cleaning dust collection sheet. By providing a dust bag bracket and a dust bag in the dust collection bin, the waste in the dust box can be transferred to the dust bag in the dust collection bin without any leakage, thereby reducing the number of times the user has to dispose of waste and improving the user experience.

[0080] Finally, note that each example in this specification is described incrementally, each example focuses on its differences from the others, and identical or similar parts between examples may be referenced to one another.

[0081] The above embodiments are used to illustrate the technical solutions of the present disclosure and are not limiting thereto. While the present disclosure has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in each of the above embodiments can still be modified or some of their technical features can be substituted equally, and that such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of each embodiment of the present disclosure.
