[0015] Selected embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0016] In related art, the dust box of an automatic cleaning device has limited capacity, so users often have to bend down to clean the dust box, resulting in a poor user experience. Therefore, an embodiment of the present disclosure provides a self-cleaning dust collecting sheet, which uses a dust collection system to concentrate dust in the dust box of the automatic cleaning device and collect it in the dust collection bin of the self-cleaning dust collecting sheet, thereby reducing the number of times the user has to dispose of the dust and improving the user experience. Specifically, regarding the self-cleaning dust collecting sheet provided by the embodiment of the present disclosure, for example, FIG. 1 is a schematic diagram illustrating the overall structure of the self-cleaning dust collecting sheet, and FIG. 2 is a schematic diagram illustrating the structure of the self-cleaning dust collecting sheet body after the dirty water tank, clean water tank, and dust collection cover of the present disclosure have been removed.

[0017] To more clearly describe the behavior of the self-cleaning dust collecting sheet, the following directions are defined. The self-cleaning dust collecting sheet is defined by three mutually perpendicular axes: a transverse axis Y, a front-to-rear axis X, and a central vertical axis Z. The direction opposite the arrow along the front-to-rear axis X, i.e., the direction in which the automatic cleaning device enters the self-cleaning dust collecting sheet, is defined as "rear," and the direction along the arrow along the front-to-rear axis X, i.e., the direction in which the automatic cleaning device leaves the self-cleaning dust collecting sheet, is defined as "forward." The transverse axis Y is substantially along the width of the body of the self-cleaning dust collecting sheet. The vertical axis Z is a direction extending upward along the bottom surface of the self-cleaning dust collecting sheet.

[0018] As shown in FIG. 1, the direction in which the self-cleaning dust collecting sheet bottom plate 1000 protrudes from the self-cleaning dust collecting sheet main body 2000 is the front, the direction toward the rear wall of the self-cleaning dust collecting sheet main body 2000 is the rear, the dust collecting bin 3000 is on the left side of the self-cleaning dust collecting sheet, the clean water tank 4000 is on the right side of the dust collecting bin 3000, and the dirty water tank 5000 is on the right side of the clean water tank 4000.

[0019] 1, the self-cleaning dust collecting sheet provided in this embodiment includes a self-cleaning dust collecting sheet bottom plate 1000 and a self-cleaning dust collecting sheet main body 2000. Here, the self-cleaning dust collecting sheet bottom plate 1000 is detachably connected to the self-cleaning dust collecting sheet main body 2000, and more specifically, the self-cleaning dust collecting sheet bottom plate 1000 is detachably connected to a main body base 6000 below the self-cleaning dust collecting sheet main body 2000. The detachable connection method makes transportation and maintenance easier.

[0020] The self-cleaning dust collecting sheet body 2000 is configured to collect dirt in the dust box of the automatic cleaning device. In some embodiments, the self-cleaning dust collecting sheet body 2000 is further lined with components such as a dust collecting bin 3000, a clean water tank 4000, and a dirty water tank 5000.

[0021] 2, the self-cleaning dust collecting sheet main 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 collecting sheet main body 2000. The water storage chamber may further include a clean water bin for accommodating the clean water tank 4000 and a dirty water bin for accommodating the dirty water tank 5000. The dust collection chamber 2100 opens upward and forward and is located at the top end of the self-cleaning dust collecting sheet main body 2000 alongside the water storage chamber 2700. A dust collection cover 2800 is provided on the dust collection chamber 2100, fitting to the opening of the dust collection chamber 2100. The dust collection cover 2800 is detachably engaged on the dust collection chamber 2100, and the dust collection chamber 2100, together with the dust collection cover 2800, form a dust collection bin 3000 for accommodating a dust container. At least a portion of the outer surface of the dust collection cover 2800 functions as part of the exterior 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 allows the dirty water tank 5000, the clean water tank 4000, and the dust collection cover 2800 to be easily attached and detached.

[0022] A body base 6000 is located below the self-cleaning dust collecting sheet body 2000. In some embodiments, the body base 6000 is integrally provided below the self-cleaning dust collecting sheet body 2000. The body base 6000 is further abutted against the bottom plate 1000 of the self-cleaning dust collecting sheet. Specifically, the bottom plate 1000 of the self-cleaning dust collecting sheet and the body base 6000 are arranged sequentially along a second direction, which is opposite to the arrow of the front-rear axis X.

[0023] The dust collection opening 6100 is provided on the main body base 6000, and is located approximately at the edge of the connection between the main body base 6000 and the self-cleaning dust collecting sheet bottom plate 1000. The dust collection opening 6100 is configured to be connected to the dust outlet of the automatic cleaning device, and dust in the dust box 300 of the automatic cleaning device enters the dust collection chamber 2100 of the self-cleaning dust collecting sheet main body 2000 through the dust collection opening 6100. In some embodiments, a sealing rubber gasket is further provided around the dust collection opening 6100, and the sealing rubber gasket is used to seal the abutted dust collection opening 6100 and the dust outlet of the automatic cleaning device to prevent dust leakage.

[0024] In some embodiments, the main body base 6000 further includes a cleaning groove 6200, which is configured to clean the cleaning member of the automatic cleaning device, for example, to replenish cleaning fluid in the wet cleaning module of the automatic cleaning device, and / or to accommodate dirt removed from the wet cleaning module, and / or to collect wastewater generated during the cleaning process of the wet cleaning module to facilitate subsequent disposal of the dirt and wastewater. In some embodiments, the cleaning groove 6200 is located behind the dust collection port 6100.

[0025] In some embodiments, the self-cleaning dust collecting sheet further includes an air duct, one end of which communicates with the dust collection port 6100 of the main body base 6000 and the other end of which communicates with the dust collection chamber 2100. When the self-cleaning dust collecting sheet is in a dust collecting state, a sufficient negative pressure is generated in the dust collection bin 3000, and dust in the dust box 300 is sucked into the dust bag in the dust collection chamber 2100 through the dust collection port 6100 and the air duct.

[0026] 2 and 3, in some embodiments, the dust collection chamber 2100 includes a dust collection chamber rear wall 2134 and a pair of opposite 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 being adjacent to the outer wall of the self-cleaning dust collection sheet body 2000, the first dust collection chamber side wall 2131 being opposite 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 being adjacent to the dust collection chamber rear wall 2134.

[0027] Specifically, the end faces of the dust collection chamber side walls may have an arc-shaped structure, and the height of the dust collection chamber side walls tends to gradually decrease along the direction of the arrow of the front-rear axis X, so that at the adjacent part of the dust collection chamber side walls and the dust collection chamber rear wall 2134, the height of the dust collection chamber side walls is equal to the height of the dust collection chamber rear wall 2134. The dust collection chamber side walls adopt an arc-shaped structure with a low front and a high rear, which makes it easier to attach and detach the dust collection cover 2800 and improves the aesthetic appearance to a certain extent.

[0028] 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 integral with the self-cleaning dust collection sheet main body 2000, which can improve the stability of the dust collection chamber 2100 and prevent the dust collection chamber 2100 from shaking relative to the self-cleaning dust collection sheet main body 2000.

[0029] 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 in a direction away from the cleaning and dust collection sheet main body 2000. The dust collection chamber rear wall 2134 and the dust collection chamber side walls are disposed around the circumferential inner wall 2150 and are spaced apart from the circumferential inner wall 2150. The height of every portion of the circumferential inner wall 2150 may vary, and in some embodiments, the height of the circumferential inner wall 2150 tends to gradually decrease along the direction of the arrow of the front-rear axis X. Such a low-front-high structural design of the circumferential inner wall 2150 can facilitate attachment and detachment of the dust collection cover 2800.

[0030] In some embodiments, the circumferential inner wall 2150 may have a closed loop structure, including a front inner wall 2153, a first side inner wall 2151, a rear inner wall 2154, and a second side inner wall 2152 connected in sequence, where the front inner wall 2153 faces the rear inner wall 2154, and the first side inner wall 2151 faces the second side inner wall 2152. Furthermore, each inner wall of the circumferential inner wall 2150 has a corresponding relationship with the dust collection chamber rear wall 2134 and the dust collection chamber side wall. 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 dust collection chamber rear wall 2134 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.

[0031] In some embodiments, the inner circumferential wall 2150 and the bottom wall of the self-collection chamber 2100 are of one piece, which can improve the stability of the inner circumferential wall 2150 .

[0032] In some embodiments, the dust collection chamber 2100 may further include a sealing pad 2140, which is disposed around the circumferential inner wall 2150, and the dust collection chamber rear wall 2134 and dust collection chamber side wall are disposed around the sealing pad 2140. In some embodiments, the sealing pad 2140 has a closed loop structure, and the width of each portion of the sealing pad 2140 may be equal to or slightly larger than the distance between the circumferential inner wall 2150, the dust collection chamber rear wall 2134, and the dust collection chamber side wall, so that the sealing pad 2140 tightly contacts the circumferential inner wall 2150, the dust collection chamber rear wall 2134, and the dust collection chamber side wall. The sealing pad 2140 may be made of various natural or synthetic rubbers. The sealing pad 2140 allows the dust collection chamber 2100 and the dust collection cover 2800, which is fitted to the dust collection chamber 2100, to tightly abut against each other, forming a sealed dust collection bin 3000.

[0033] 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 mount a dust bag. The dust bag bracket 2110 is provided within the dust collection chamber 2100 and extends from the bottom of the dust collection chamber in a direction away from the self-cleaning dust collection sheet main body 2000. The dust bag bracket 2110 may be attached to a circumferential inner wall 2150 of the dust collection chamber 2100 by a fastening member such as a screw, or 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 a first inner side wall 2151, and the side wall of the dust bag bracket 2110 facing away from the dust collection chamber 2100 may be integrally formed with the first inner side wall 2151, which may improve the stability of the dust bag bracket 2110. The dust bag bracket 2110 has a hollow cavity therein, which functions as a part of an air duct for 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 on the bracket side wall, which communicates with the dust collection port 6100 via an air duct, and the air duct is configured to guide dust into the dust collection bin 3000, for example, to a dust bag in the dust collection bin 3000. The dust outlet is configured to communicate with the dust bag inlet to collect dust in the dust bag.

[0034] 4 and 5 , in some embodiments, the dust collection cover 2800 includes a dust collection cover main body 2810 and a dust collection cover wall 2820. Here, the dust collection cover main body 2810 is located above the dust collection cover wall 2820, and the dust collection cover wall 2820 extends from the dust collection cover main body 2810 in a direction away from the dust collection cover main body 2810. The dust collection cover main body 2810 forms an accommodation space together with the dust collection cover wall 2820, and in response to the dust collection cover 2800 being fitted to the dust collection chamber 2100, the circumferential inner wall 2150 is accommodated within the accommodation space, and the free end of the dust collection cover wall 2820 away from the dust collection cover main body 2810 comes into close contact with the sealing pad 2140 to form a sealed dust collection bin 3000.

[0035] In some embodiments, the dust collection cover wall 2820 further includes a dust collection cover front wall 2823, a dust collection cover first side wall 2821, a dust collection cover rear wall 2824, and a dust collection cover second side wall 2822, which are connected in sequence. Here, the dust collection cover front wall 2823 is disposed opposite the dust collection cover rear wall 2824, and the dust collection cover first side wall 2821 is disposed opposite the dust collection cover second side wall 2822.

[0036] In response to the dust collection cover 2800 being fitted to the dust collection chamber 2100, at least a portion of the first side wall 2821 of the dust collection cover is sandwiched between the first dust collection chamber side wall 2131 and the first side inner wall 2151, at least a portion of the second side wall 2822 of the dust collection cover is sandwiched between the second dust collection chamber side wall 2132 and the second side inner wall 2152, and the dust collection cover rear wall 2824 is sandwiched between the dust collection chamber rear wall 2134 and the rear inner wall 2154.

[0037] In some embodiments, the dust collection cover 2800 further includes a handle portion 2811, which is provided on the side of the dust collection cover main body 2810 away from the dust collection cover wall 2820. The handle portion 2811 may be a structure such as a pull ring, pull rod, or handle provided on the dust collection cover main body 2810. The provision of the handle portion 2811 makes it easier to attach and detach the dust collection cover 2800, and is convenient for the user to remove dust from the dust collection bin 3000 on a daily basis.

[0038] In some embodiments, the dust collection cover 2800 may further include a restricting member 2825, which is provided on the dust collection cover wall 2820. The restricting member 2825 may cooperate with a restricting portion provided on the dust collection chamber 2100, allowing the dust collection cover 2800 to be securely positioned on the dust collection chamber 2100 without shaking. The restricting portion may be provided on at least one of the dust collection chamber rear wall 2134 and the dust collection chamber side wall. The restricting member 2825 cooperates with the restricting portion in a one-to-one correspondence. In the embodiment shown in FIG. 4 , the restricting member 2825 is provided on the second side wall 2822 of the dust collection cover, and a restricting portion corresponding to the restricting member 2825 is provided on the second dust collection chamber side wall 2132. In response to fitting the dust collection cover 2800 onto the dust collection chamber 2100, the restricting member 2825 abuts against the restricting portion.

[0039] In some embodiments, support ribs 2826 are provided on at least one of the bottom wall of the dust collection chamber, the inner circumferential wall 2150, and the dust collection cover wall 2820. The support ribs 2826 may be strip-shaped structures that protrude outward from the surface. In the embodiment shown in FIG. 4 , the support ribs 2826 are provided on at least the inner surface of the second side wall 2822 of the dust collection cover, and a plurality of support ribs 2826 are provided on the inner surface of the second side wall 2822 of the dust collection cover. The provision of the support ribs 2826 prevents the dust bag in the dust collection bin 3000 from sticking to the bottom wall of the dust collection chamber, the inner circumferential wall 2150, and / or the dust collection cover wall 2820, which can adversely affect the airflow outflow from the dust bag.

[0040] The present disclosure further provides an automatic cleaning device and a dust collection system including the self-cleaning dust collection sheet in the above embodiment.

[0041] The dust collection cover is designed to fit tightly into the dust collection chamber when the fan is turned on, further improving dust collection efficiency. The exposed dust collection cover design allows users to more intuitively observe the situation inside the cover, facilitating more timely maintenance of the dust collection chamber, such as replacing the dust bag.

[0042] In related art, the dust box of an automatic cleaning device has limited capacity, so users often have to bend down to clean the dust box, resulting in a poor user experience. Therefore, an embodiment of the present disclosure provides a self-cleaning dust collection sheet, and a dust collection system is used to concentrate and collect dust in the dust box of the automatic cleaning device into a dust collection bin of the self-cleaning dust collection sheet. A dust bag bracket and a dust bag are provided in the dust collection bin, so that the dust in the dust box can be transferred to the dust bag in the dust collection bin without leakage, reducing the number of times the user has to dispose of the dust and improving the user experience. The dust bag adopts a cooperative design of an engagement 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 the dust in the dust bag from being left in the dust collection bin.

[0043] Specifically, regarding the self-cleaning dust collecting sheet provided by the embodiments of the present disclosure, as an example, FIG. 1 is a schematic diagram illustrating the overall structure of the self-cleaning dust collecting sheet, and FIG. 2 is a schematic diagram illustrating the structure of the self-cleaning dust collecting sheet body after the wastewater tank, clean water tank, and dust collecting cover of the present disclosure have been removed.

The dust collection opening 6100 is configured to be connected to the dust outlet of the automatic cleaning device, and dust in the dust box 300 of the automatic cleaning device enters the dust collection chamber 2100 of the self-cleaning dust collecting sheet main body 2000 through the dust collection opening 6100. In some embodiments, a sealing rubber gasket is further provided around the dust collection opening 6100, which is used to abut the dust collection opening 6100 and the dust outlet of the automatic cleaning device and then seal them to prevent dust leakage.

[0048] In some embodiments, the main body base 6000 further includes a cleaning groove 6200, which is configured to clean the 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 accommodate dust removed from the wet cleaning module, and / or to collect wastewater generated during the cleaning process of the wet cleaning module, thereby facilitating subsequent disposal of the dust and wastewater. In some embodiments, the cleaning groove 6200 is provided behind the dust collection port 6100.

[0049] In some embodiments, the self-cleaning dust collecting sheet further includes an air duct, one end of which communicates with the dust collection port 6100 of the main body base 6000 and the other end of which communicates with the dust collection chamber 2100. When the self-cleaning dust collecting sheet is in a dust collecting state, a sufficient negative pressure is generated in the dust collection bin 3000 to suck dust in the dust box 300 through the dust collection port 6100 and the air duct into the dust bag in the dust collection chamber 2100.

[0050] FIG. 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 FIG. 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.

[0051] 1-2, in some embodiments, the self-cleaning dust collection sheet further includes a dust bag bracket 2110 configured to mount a dust bag. The dust bag bracket 2110 is disposed within the dust collection bin 3000 and may be attached to the inner wall of the dust collection bin 3000 by a fastening member such as a screw, or may be fixed to the bottom surface of the dust collection bin 3000 via the bottom of the dust bag bracket 2110.

[0052] There is a hollow cavity inside the dust bag bracket 2110, which serves as a part of the air duct of the self-cleaning dust collecting sheet, for example, the tail end of the air duct.

[0053] 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 mouth 6100 through an air duct, and the air duct is configured to guide dust into the dust collection bin 3000, for example, to a dust bag in the dust collection bin 3000. The dust outlet 2112 is configured to communicate with an inlet of a dust bag to collect dust in the dust bag.

[0054] 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 positioned in the first position, the sliding baffle 2113 blocks the dust outlet 2112, and in response to the sliding baffle 2113 being positioned in the second position, the sliding baffle 2113 exposes the dust outlet 2112. Because a dust bag is a consumable item, it is removably attached to the dust bag bracket 2110. By adopting the above design, the dust bag bracket 2110 can block the dust outlet 2112 with the sliding baffle 2113 when no dust bag is attached, and isolate the dust collection bin 3000 from the air duct, so that the suction force generated by the fan does not enter the air duct from the dust collection bin, and it is possible to prevent dust from entering the dust collection bin 3000 when no dust bag is attached.

[0055] 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 a 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 an 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; the dust bag is not shown in Figures 9 and 9B.

[0056] In some embodiments, as shown in FIGS. 8-9B, the present disclosure further provides a dust bag 2120, which is removably attached to the dust bag bracket 2110 and configured to collect dust.

[0057] 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 of, for example, a material that is breathable but can filter fine particles, such as nonwoven fabric or paper material, and is configured to contain the dust. 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 inlet of the dust bag body 2121. The sliding plate 2123 is slidably connected to the engagement plate 2122 and is configured to switch between a closed position and an open position, and in response to the sliding plate 2123 being positioned in the closed position, the sliding plate 2123 blocks the engagement plate opening 21221, and in response to the sliding plate 2123 being positioned in the open position, the sliding plate 2123 exposes the engagement plate opening 21221.

[0058] 8 and 6, the sliding plate 2123 has a sliding plate opening 21231, and when the sliding plate 2123 is positioned at the closed position, the orthogonal projection of the sliding plate opening 21231 onto the engagement plate 2122 does not overlap with the engagement plate opening 2821, and the sliding plate 2123 shields the engagement plate opening 22121, as shown in Fig. 8. When the sliding plate 2123 is positioned at the open position, the orthogonal projection of the sliding plate opening 21231 onto the engagement plate 2122 at least partially overlaps with the engagement plate opening 21221, and the sliding plate 2123 exposes at least a portion of the engagement plate opening 21221 through the sliding plate opening 21231, as shown in Fig. 9.

[0059] In some embodiments, the size of the sliding plate opening 21231 is, for example, larger than the engagement plate opening 21221, and in response to the sliding plate 2123 being positioned in the closed position, the orthogonal 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, for example, smaller than the engagement plate opening 21221, and in response to the sliding plate 2123 being positioned in the closed position, the orthogonal projection of the sliding plate opening 21231 onto the engagement plate 2122 is located within the engagement plate opening 21221. In some embodiments, the size of the sliding plate opening 21231 is, for example, equal to the engagement plate opening 21221, and in response to the sliding plate 2123 being positioned in the closed position, the orthogonal projection of the sliding plate opening 21231 onto the engagement plate 2122 substantially overlaps with the engagement plate opening 21221.

[0060] The sliding plate 2123 and the engagement plate 2122 slide together to close the dust bag entrance, thereby preventing dust from leaking out of the dust bag.

[0061] 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, protruding toward the sliding plate 2123. In response to the sliding plate 2123 being positioned in the open position, the flexible rubber ring 21224 passes through the sliding plate opening 21231 and protrudes in a direction away from the sliding plate 2123. When the sliding plate opening 21231 and the engagement plate opening 21221 are connected, the flexible rubber ring 21224 closes the gap generated by the butt-jointing of the two openings of the sliding plate 2123 and the engagement plate 2122, thereby achieving a sealed connection between the sliding plate opening 21231 and the engagement plate opening 21221. When the sliding plate 2123 is not in the open position, for example, in 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, and the sliding plate 2123 is stably held in the closed position, thereby preventing dust from scattering in the dust bag.

[0062] 8 and 9 , the sliding plate 2123 is slidable relative to the engagement plate 2122 in a first direction M, and the sliding plate 2123 includes limiting protrusions 21243 provided on at least one side of the sliding plate 2123, for example, on both sides of the sliding plate 2123, where the number of limiting protrusions 21243 is, for example, two, and protrudes from the sliding plate 2123 in a second direction perpendicular to the first direction M. The engagement plate 2122 includes limiting members 21223 provided on both ends of the engagement plate 2122 in the first direction and configured to stop the limiting protrusions 21233 in the first direction M and prevent the sliding plate 2123 from disengaging from the engagement plate 2122. The number of limiting members 21223 is, for example, four, and they are distributed symmetrically on both sides of the engagement plate 2122. When the sliding plate 2123 slides relative to the engaging plate 2122, the limiting protrusions 21233 can only move between the corresponding limiting members 21223 at both ends of the engaging plate 2122 in the first direction.

[0063] In some embodiments, the sliding plate 2123 further includes a handle portion 21232, which is provided at one end of the sliding plate in a first direction M and is configured to facilitate an operator's grip to move the sliding plate 2123.

[0064] The dust bag 2120 is detachably mounted on the dust bag bracket 2110, and when the dust bag 2120 is mounted on the dust bag bracket 2110, the sliding baffle 2123 is in the second position to expose the dust outlet, and when the sliding plate is in the open position, the engagement plate opening 21221 is connected to the dust outlet 2112. With the above arrangement, when the dust bag bracket 2110 is not mounted on the dust bag 2120, the sliding baffle 2113 is in the first position to block the dust outlet 2112, so that the suction force generated by the fan does not enter the air duct from the dust collection bin, preventing dust from entering the dust collection bin 3000 when the dust bag 2120 is not mounted.

[0065] When the dust bag 2120 is removed from the dust bag bracket 2110, the sliding plate is in the closed position 2123 to prevent the dust in the dust bag from scattering into the dust collection bin. Because the dust bag is sealed, the dust in the dust bag can be prevented from scattering into the external environment.

[0066] When the dust bag 2120 is not attached to the dust bag bracket 2110, its sliding plate 2123 blocks the engagement plate opening 21221 of the engagement plate 2122, and when the dust bag 2120 is attached to the dust bag bracket 2110, the sliding plate 2123 and the engagement plate 2122 work together to push the sliding baffle 2113 from the first position to the second position and fix it at the second position, and when the dust bag 2120 is detached from the dust bag bracket 2110, its sliding plate 2123 blocks the engagement plate opening 21221 to prevent 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 dust in the dust box of the automatic cleaning device is collected sequentially 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 into the dust bag main body 2121.

[0067] FIG. 10 is a pre-assembled schematic diagram of a dust bag bracket and a dust bag provided by some embodiments of the present disclosure, and FIG. 11 is a schematic diagram showing an assembled structure of a dust bag bracket and a dust bag provided by some embodiments of the present disclosure.

[0068] 6 to 11 , the dust bag bracket 2110 includes a sliding groove 2114, at least a portion of the sliding baffle 2113 is located in the sliding groove 2114, the sliding baffle 2113 is slidable along the extension direction X′ of the sliding groove 2114, and is switchable between a first position and a second position. The number of sliding grooves 2114 may be, for example, one or more, and as shown in FIGS. 6 to 11 , the number of sliding grooves 2114 may be, for example, two, which are provided at opposite ends of the bracket side wall 2111 of the dust bag bracket 2110, respectively, and the two sliding grooves 2114 respectively accommodate opposite ends of the sliding baffle 2113, allowing the sliding baffle 2113 to slide along the extension direction X′ of the sliding groove 2114.

[0069] 6 to 11 , the engagement plate 2122 and the 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 engagement plate 2122 and the sliding plate 2123 of the dust bag 2120 can be inserted into the two sliding grooves 2114, respectively. In response to the dust bag 2120 being attached to the dust bag bracket 2110, the sliding plate 2123 is in an open position, exposing the engagement plate opening 21221, and the sliding baffle 2113 is in a second position, exposing the dust outlet 2112, and the engagement plate opening 21221 and the dust outlet 2112 are abutted against each other.

[0070] 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 extension direction X′ of the sliding groove 2114. When the two are attached, the engagement plate 2122 and sliding plate 2123 of the dust bag 2120 face the bracket side wall 2111 of the dust bag bracket 2110, and during the process of inserting the engagement plate 2122 and sliding plate 2123 into the sliding groove 2114 along the extension direction X′ of the sliding groove 2114, they push the sliding baffle 2113 to move from the first position to the second position.

[0071] In some embodiments, a sliding baffle protrusion 21131 is provided at the lower end of the sliding baffle 2113, and the sliding baffle protrusion 21131 is a strip-shaped protrusion that extends 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 abuts against the sliding baffle protrusion 21131. When the sliding plate 2123 slides downward in the extension direction X' of the sliding groove 2114, the abutting lower end of the sliding plate 2123 and the sliding baffle protrusion 21131 can push the sliding baffle 2113 together and slide along the extension direction X' of the sliding groove. In some embodiments, a sliding plate protrusion 21233 is also provided on the lower end of the sliding plate 2123, and the sliding plate protrusion 21233 is a strip-shaped protrusion that extends 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 protrusion 21233 abuts just above the sliding baffle protrusion 21131. Due to the abutting sliding plate protrusion 21233 and the sliding baffle protrusion 21131, when the sliding plate 2123 slides downward in the extension direction X' of the sliding groove 2114, it can push the sliding baffle 2113 and slide together in the extension direction X' of the sliding groove.

[0072] FIG. 11 shows a cross-sectional view of an assembly structure of a dust bag bracket and a dust bag provided by some embodiments of the present disclosure, and FIG. 12 is a schematic diagram showing an assembly structure of a dust bag bracket and a dust bag provided by some embodiments of the present disclosure.

[0073] 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 arcuate manner as indicated by the arrow in FIG. 27 , and the engagement plate 2122 includes an engagement groove 21222 that fits with the buckle portion 21141, and the buckle portion 21141 engages with the engagement groove 21222 in response to the dust bag 2120 being attached to the dust bag bracket 2110. The engagement plate 2122 slides along the extension direction X′ of the sliding groove 2114 to an engagement position, and the engagement plate opening 21221 abuts against the dust outlet 2112, and 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.

[0074] The limiting protrusion 212234 on the sliding plate 2123 also functions as an unlocking protrusion 21234, and is referred to as the unlocking protrusion 21234. During the process of removing the sliding plate 2123 from the sliding groove 2114, the limiting protrusion 212234 presses the buckle portion 21141 to disengage the buckle portion 21141 from the engaging groove 21222, thereby releasing the fastening of the engaging plate 2122 by the buckle portion 21141, and allowing the dust bag 2120 to be smoothly removed from the dust bag bracket 2110. In some embodiments, the unlocking protrusion 21234 also has a limiting effect, and cooperates with the limiting member 21223 on the engaging plate 2122 to prevent the sliding plate 2123 from being removed from the engaging plate 2122.

[0075] 13 , the dust bag bracket 2110 is provided with an elastic member 2115, such as a spring. The elastic member 2115 is connected to the sliding baffle 2113 and configured to allow the sliding baffle 2113 to have a tendency to be in a first position. When the sliding baffle 2113 is not subjected to an external force, the sliding baffle 2113 is in the first position under the action of the elastic member 2115, 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, and 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, when the number of elastic members 2115 is two, they may be provided at opposite ends of the dust bag bracket 2110, respectively.

[0076] The process of attaching and detaching the dust bag 2120 and the dust bag bracket 2110 will now be described in detail.

[0077] 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 of the dust bag 2120 is in the closed position, blocking the engagement plate opening 2122, i.e., the state shown in Figure 8. When the dust bag 2120 is attached to the dust bag bracket 2110, the engagement plate 2122 and the sliding plate 2123 are inserted into the sliding groove 2114 along the extension direction X′ of the sliding groove 2114. When a user holds the handle portion 21232 of the sliding plate 2123 and pushes the dust bag 2120 into the sliding groove 2114, the sliding plate 2123 gradually moves from the closed position to the open position relative to the engagement plate 2122, and the sliding plate opening 21231 of the sliding plate 2123 and the engagement plate opening 21221 of the engagement plate 2122 are aligned. At the same time, the engagement plate 2122 and the sliding plate 2123 push the sliding baffle 2113 from the first position to the second position, exposing the sliding baffle 2113 from the dust outlet 2112. When the engaging plate 2122 slides along the extension direction X' of the sliding groove 2114 to the engaging position, the engaging plate opening 21221 connects with the dust outlet 2112, the buckle part 21141 is clamped corresponding to the engaging groove 21222, and the dust bag 2120 is fixed to the dust bag bracket 2110. At this time, the flexible rubber ring 21224 of the dust bag passes through the sliding plate opening 21231 and abuts against the edge of the dust outlet 2112, thereby achieving a sealed connection between the engaging plate opening 21221 of the dust bag and the dust outlet 2112 of the dust bag bracket, and preventing dust leakage during the dust collection process.

[0078] During the process of removing the dust bag 2120 from the dust bag bracket 2110, an operator can grasp the handle portion 21232 of the sliding plate 2123 and gradually remove the sliding plate 2123 from the sliding groove 2114 of the dust bag bracket 2110. During this process, the sliding plate 2123 gradually moves from the open position to the closed position relative to the engaging plate 2122, so that the sliding plate 2123 covers the engaging plate opening 21221, and the unlocking protrusion 21234 on the sliding plate 2123 presses the buckle portion 21141 to lock the buckle portion 21141 into the engaging position. The sliding plate 2123 is released from the mating groove 21222, and at the same time, due to the interaction between the unlocking protrusion 21234 and the restricting member 21223 on the engaging plate 2122, the handle portion 21232 of the sliding plate 2123 is continuously pulled out, so that the sliding plate 2123 and the engaging plate 2122 are pulled out from the sliding groove 2114 of the dust bag bracket 2110, and the dust bag 2120 is released from the dust bag bracket 2110. Under the action of the elastic member, the sliding baffle 2113 returns to the first position, and the sliding baffle 2113 blocks the dust outlet 2112.

[0079] In some embodiments, a dust outlet is provided on a bracket side wall of the dust bag bracket facing into the dust collection bin and is configured to be connected to the dust bag inlet, and the dust bag bracket further includes a sliding baffle that slides on the bracket side wall and is configured to switch between a first position and a second position, such that in response to the sliding baffle being positioned in the first position, the sliding baffle blocks the dust outlet, and in response to the sliding baffle being positioned in the second position, the sliding baffle exposes the dust outlet.

[0080] In some embodiments, the self-cleaning dust collection sheet further comprises a dust bag removably mounted on a dust bag bracket, the dust bag comprising: Dust bag body and an engagement plate fixedly connected to the dust bag body and having an engagement plate opening that functions as an inlet for the dust bag; In response to the dust bag not being mounted on the dust bag bracket, the sliding baffle is in a first position, blocking the dust outlet, and in response to the dust bag being mounted on the dust bag bracket, the sliding baffle is in a second position, exposing the dust outlet and abutting the engagement plate opening against the dust outlet.

[0081] In some embodiments, the dust bag further includes a sliding plate slidably connected to the engagement plate and configured to switch between a third position and a fourth position, wherein in response to the sliding plate being positioned in the third position, the sliding plate covers the engagement plate opening, and in response to the sliding plate being positioned in the fourth position, the sliding plate exposes the engagement plate opening.

[0082] In some embodiments, the sliding plate has a sliding plate opening, and in response to the sliding plate being positioned in a third position, the sliding plate opening does not overlap with the engagement plate opening and the sliding plate shields the engagement plate opening, and in response to the sliding plate being positioned in a fourth position, the sliding plate opening substantially overlaps with the engagement plate opening and the sliding plate exposes the engagement plate opening.

[0083] In some embodiments, the dust bag bracket includes a sliding groove, at least a portion of the sliding baffle is positioned within the sliding groove, the sliding baffle slides along the extension direction of the sliding groove, an engagement plate and a sliding plate are inserted into the sliding groove and slide along the extension direction of the sliding groove, and the sliding baffle is slid along the extension direction of the sliding groove to attach the dust bag to the dust bag bracket, and in response to the dust bag being attached to the dust bag bracket, the sliding plate is in a fourth position, exposing the engagement plate opening, and the sliding baffle is in a second position, exposing the dust outlet, and the engagement plate opening and the dust outlet are abutted against each other.

[0084] In some embodiments, the dust bag bracket includes a resilient member connected to the sliding baffle to bias the sliding baffle to the first position.

[0085] In some embodiments, an engagement groove for the engagement plate is provided on the engagement plate, a buckle portion is provided in the sliding groove, and the buckle portion engages with the engagement groove for the engagement plate in response to the dust bag being attached to the dust bag bracket.

[0086] In some embodiments, an unlocking protrusion is further provided on the sliding plate, configured to disengage the buckle portion from the engagement groove for the engagement plate during the process of removing the dust bag from the dust bag bracket.

[0087] The present disclosure further provides a dust collection system comprising an automatic cleaning device, the self-cleaning dust collection sheet in the above embodiment.

[0088] In the self-cleaning dust collecting sheet provided by the embodiments of the present disclosure, the dust collection system concentrates the dust in the dust box of the automatic cleaning device and collects it in the dust collecting bin of the self-cleaning dust collecting sheet, and by providing a dust bag bracket and a dust bag in the dust collecting bin, the dust in the dust box can be transferred to the dust bag in the dust collecting bin basically without leakage, reducing the number of times the user has to dispose of the dust and improving the user experience.

[0089] Finally, please note that each embodiment in this specification will be described progressively, with each embodiment focusing on differences from other embodiments, and that identical or similar parts between each embodiment may be referenced to each other.

[0090] The above examples are used to explain the technical solutions of the present disclosure, but are not intended to limit them.
