The dust collection port 6100 is configured to be connected to the dust outlet of the automatic cleaning device, and the 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 port 6100. In some embodiments, a sealing rubber gasket is further provided around the dust collection port 6100, which is used to butt the dust collection port 6100 and the dust outlet of the automatic cleaning device and then seal them to prevent dust leakage.

[0047] In some embodiments, the main body base 6000 further includes a cleaning groove 6200, which is configured to clean the cleaning member on the automatic cleaning device, for example, to replenish cleaning liquid to 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, so as to facilitate subsequent treatment of the dirt and wastewater. In some embodiments, the cleaning groove 6200 is provided behind the dust collection port 6100.

[0048] 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 collection 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.

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

[0050] 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 disposed on an 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.

[0051] 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.

[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 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.

[0053] The dust bag bracket 2110 further includes a sliding baffle 2113 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 located in the first position, the sliding baffle 2113 blocks the dust outlet 2112, and in response to the sliding baffle 2113 being located in the second position, the sliding baffle 2113 exposes the dust outlet 2112. Since a dust bag is a consumable item, it is removably attached to the dust bag bracket 2110. By adopting the above design, when the dust bag bracket 2110 is not attached to a dust bag, the sliding baffle 2113 can block the dust outlet 2112 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, thereby preventing dust from entering the dust collection bin 3000 when no dust bag is attached.

[0054] FIG. 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; FIG. 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; FIG. 9A is a schematic diagram showing a partial structure of a dust bag provided by some embodiments of the present disclosure; FIG. 9B is a schematic diagram showing a cross-sectional structure in FIG. 9A; FIG. 9A shows a cross-section of the dust bag; the dust bag is not shown in FIG. 9 and FIG. 9B.

[0055] 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 dirt.

[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 of a material that is breathable but can filter fine particles, such as nonwoven fabric, paper material, etc., and the dust bag body is configured to accommodate 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, and the engagement plate opening 21221 serves as an inlet of the dust bag body 2121. A sliding plate 2123 is slidably connected to the engagement plate 2122 and 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 covers 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.

[0057] Specifically, as shown in Figures 8 and 6, the sliding plate 2123 has a sliding plate opening 21231, and in response to the sliding plate 2123 being located at a 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 Figure 8. In response to the sliding plate 2123 being located at an 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 Figure 9.

[0058] In some embodiments, the size of the sliding plate opening 21231 is, for example, larger than the engagement plate opening 21221, such that in response to the sliding plate 2123 being positioned in a closed position, an 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, such that in response to the sliding plate 2123 being positioned in a closed position, an orthogonal projection of the sliding plate opening 21231 onto the engagement plate 2122 falls 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, such that in response to the sliding plate 2123 being positioned in a closed position, an orthogonal projection of the sliding plate opening 21231 onto the engagement plate 2122 substantially overlaps with the engagement plate opening 21221.

[0059] 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.

[0060] In some embodiments, as shown in Figures 8 to 9B, a flexible rubber ring 21224 protruding toward the sliding plate 2123 is provided on the edge of the engagement plate opening 21221, and 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 butted together, the gap generated by the buttment of the two openings of the sliding plate 2123 and the engagement plate 2122 is blocked, and a sealed connection between the sliding plate opening 21231 and the engagement plate opening 21221 is achieved. In response to the sliding plate 2123 not being in the open position, for example being 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, so that the sliding plate 2123 and the engaging plate 2122 cannot slide relative to each other unless a certain external force is applied, and the sliding plate 2123 is stably held in the closed position, thereby preventing the dispersion of dust in the dust bag.

[0061] In some embodiments, as shown in Figures 8 and 9, the sliding plate 2123 can slide in a first direction M relative to the engagement plate 2122, and the sliding plate 2123 includes a limiting protrusion 21243 provided on at least one side of the sliding plate 2123, for example, on both sides of the sliding plate 2123, and the number of the limiting protrusions 21243 is, for example, two, and protrudes from the sliding plate 2123 toward a second direction perpendicular to the first direction M. The engagement plate 2122 includes limiting members 21223 provided at 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 the limiting members 21223 is, for example, four, and is distributed symmetrically on both sides of the engagement plate 2122. When the sliding plate 2123 slides relative to the engagement plate 2122, the limiting protrusions 21233 can only move between the corresponding limiting members 21223 at both ends of the engagement 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 an operator's grip to move the sliding plate 2123.

[0063] The dust bag 2120 is detachably mounted on the dust bag bracket 2110, and in response to the dust bag 2120 being mounted on the dust bag bracket 2110, the sliding baffle 2123 is in the second position to expose the dust outlet, and in response to the sliding plate being in the open position, the engagement plate opening 21221 is connected to the dust outlet 2112. With the above-mentioned installation, 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 bin, and it is possible to prevent dust from entering the dust bin 3000 to which 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, which prevents the dust in the dust bag from dispersing into the dust bin. Because it is a sealed dust bag, it can prevent the dust in the dust bag from dispersing into the outside environment.

[0065] When the dust bag 2120 is not attached to the dust bag bracket 2110, the sliding plate 2123 covers 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 act 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 removed from the dust bag bracket 2110, the sliding plate 2123 covers 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 sequentially collected in 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] 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 the dust bag bracket and the 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 in the sliding groove 2114, the sliding baffle 2113 is slidable along the extension direction X' of the sliding groove 2114, and further, is switchable between a first position and a second position. The number of the sliding grooves 2114 may be, for example, one or more, and as shown in Figures 6 to 11, the number of the sliding grooves 2114 may be, for example, two, which are provided at both opposing ends of the bracket side wall 2111 of the dust bag bracket 2110, respectively, and the two sliding grooves 2114 are configured to respectively accommodate the opposing ends of the sliding baffle 2113, and the sliding baffle 2113 is slidable along the extension direction X' of the sliding groove 2114.

[0068] 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 extension direction X' of the sliding groove 2114, and push the sliding baffle 2113 to slide along the extension 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.

[0069] 10, in the process of mounting 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 the 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 engagement plate 2122 and the sliding plate 2123 into the sliding groove 2114 along the extension 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 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 along the extension direction X' of the sliding groove 2114, the abutted lower end of the sliding plate 2123 and the sliding baffle protrusion 21131 can push the sliding baffle 2113 and slide together along the extension direction X' of the sliding groove. In some embodiments, a sliding plate protrusion 21233 is also provided at the lower end of the sliding plate 2123, which is a strip-shaped protrusion that extends along the lower edge of the sliding plate 2123 toward the dust collecting 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. When the sliding plate 2123 slides downward along the extension direction X' of the sliding groove 2114, the sliding plate protrusion 21233 and the sliding baffle protrusion 21131 abut against each other, the sliding plate 2123 can push the sliding baffle 2113 and slide together along the extension direction X' of the sliding groove.

[0071] 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.

[0072] 11 and 12, a buckle portion 21141, for example an elastic buckle, is provided in the sliding groove 2114 and can move in an approximately arc shape as shown by the arrow in FIG. 27, and the engagement plate 2122 includes an engagement groove 21222 that fits the buckle portion 21141, and the buckle portion 21141 is engaged 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, the engagement plate opening 21221 is abutted 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.

[0073] The limiting protrusion 212234 on the sliding plate 2123 also functions as an unlocking protrusion 21234, and is also called the unlocking protrusion 21234, which, during the process of removing the sliding plate 2123 from the sliding groove 2114, can press the buckle portion 21141 to remove the buckle portion 21141 from the engaging groove 21222, release the fastening of the engaging plate 2122 by the buckle portion 21141, and smoothly remove the dust bag 2120 from the dust bag bracket 2110. In some embodiments, the unlocking protrusion 21234 further 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.

[0074] In some embodiments, as shown in FIG. 13, the dust bag bracket 2110 is provided with an elastic member 2115, for example 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, 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 inside the dust bag bracket 2110, the extension direction of the elastic member 2115 is substantially consistent with the extension direction of the sliding groove 2114, and one end of the elastic member 2115 is fixed to the upper part 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 both opposing ends of the dust bag bracket 2110, respectively.

[0075] The process of attaching and detaching the dust bag 2120 and the dust bag bracket 2110 will now be described in detail.

[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 a first position, blocking the dust outlet 2112, and the sliding plate 2123 on the dust bag 2120 is in a closed position, blocking the engagement plate opening 2122, i.e., as shown in FIG. 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 to push 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 on 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 to move it from the first position to the second position, and the sliding baffle 2113 is exposed 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 abuts against the edge of the dust outlet 2112, thereby achieving sealing and abutment between the engagement plate opening 21221 of the dust bag and the dust outlet 2112 of the dust bag bracket, and thus preventing dust leakage during the dust collection process.

[0077] In 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. In this process, the sliding plate 2123 gradually moves from the open position to the closed position relative to the engagement plate 2122, so that the sliding plate 2123 covers the engagement plate opening 21221, and the lock release protrusion 21234 on the sliding plate 2123 presses the buckle portion 21141 to close the buckle portion 21141. The sliding plate 2123 is disengaged from the engagement groove 21222, and at the same time, due to the interaction between the unlocking protrusion 21234 and the limiting member 21223 on the engagement plate 2122, the handle portion 21232 of the sliding plate 2123 is continuously pulled out, so that the sliding plate 2123 and the engagement plate 2122 are pulled out from the sliding groove 2114 of the dust bag bracket 2110, and the dust bag 2120 is disengaged 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 covers the dust outlet 2112.

[0078] The present disclosure further provides an automatic cleaning device, a dust collection system comprising the self-cleaning dust collection sheet in the above embodiment.

[0079] In the self-cleaning dust collecting sheet provided by the embodiment of the present disclosure, the dust in the dust box of the automatic cleaning device is concentrated and collected in the dust collecting bin of the self-cleaning dust collecting sheet by the dust collection system, and a dust bag bracket and a dust bag are provided in the dust collecting bin, so that the dust in the dust box can be transferred to the dust bag in the dust collecting bin basically without leakage, thereby reducing the number of times the user has to dispose of the dust and improving the user experience.
