[0014] Selected embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0015] In related art, the dust box of an automatic cleaning device has limited capacity, requiring users to frequently bend down to clean the dust box, resulting in a poor user experience. To address this issue, an embodiment of the present disclosure provides a self-cleaning dust collection holder, 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 collection holder, thereby reducing the number of times the user has to dispose of the dust and improving the user experience. Specifically, the self-cleaning dust collection holder provided by the embodiment of the present disclosure includes, for example, FIG. 1 exemplarily shows a schematic diagram of the overall structure of the self-cleaning dust collection holder, and FIG. 2 exemplarily shows a schematic diagram of the structure of the self-cleaning dust collection holder body after the dirty water tank, clean water tank, and dust collection cover of the present disclosure have been removed.

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

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

[0018] 1, the self-cleaning dust collection holder provided in this embodiment includes a self-cleaning dust collection holder bottom plate 1000 and a self-cleaning dust collection holder main body 2000. Here, the self-cleaning dust collection holder bottom plate 1000 and the self-cleaning dust collection holder main body 2000 are detachably connected, specifically, the self-cleaning dust collection holder bottom plate 1000 is detachably connected to a main body base 6000 at the bottom of the self-cleaning dust collection holder main body 2000. The detachable connection method makes it easy to carry and maintain.

[0019] The self-cleaning dust collection holder body 2000 is configured to collect dirt in the dust box of the automatic cleaning device. In some embodiments, assemblies such as a dust collection bin 3000, a clean water tank 4000, and a dirty water tank 5000 are arranged on the self-cleaning dust collection holder body 2000.

[0020] 2, the self-cleaning dust collection holder body 2000 includes a water storage cavity 2700 and a dust collection cavity 2100. The opening of the water storage cavity 2700 is provided at the top of the self-cleaning dust collection holder body 2000 facing upward and forward, and the water storage cavity further includes a clean water bin for accommodating the clean water tank 4000 and a dirty water bin for accommodating the dirty water tank 5000. The opening of the dust collection cavity 2100 is aligned with the water storage cavity 2700 facing upward and forward at the top end of the self-cleaning dust collection holder body 2000. A dust collection cover 2800 is provided on the dust collection cavity 2100, fitting to the opening of the dust collection cavity 2100. The dust collection cover 2800 is detachably coupled to the dust collection cavity 2100, and the dust collection cavity 2100, together with the dust collection cover 2800, form a dust collection bin 3000 that accommodates a garbage collection device. At least a portion of the outer surface of the dust collection cover 2800 is used as part of the exterior surface of the self-cleaning dust collection holder. Because the water storage cavity 2700 and the dust collection cavity 2100 are designed facing upward and forward, the dirty water tank 5000, the clean water tank 4000, and the dust collection cover 2800 can be easily attached and detached.

[0021] The bottom of the self-cleaning dust collection holder body 2000 includes a body base 6000. In some embodiments, the body base 6000 is integrally provided below the self-cleaning dust collection holder body 2000. The body base 6000 abuts against the self-cleaning dust collection holder bottom plate 1000. Specifically, the self-cleaning dust collection holder bottom plate 1000 and the body base 6000 are sequentially arranged along a second direction, which is opposite to the arrow of the front-rear axis X.

[0022] The dust collection opening 6100 is provided on the main body base 6000 and is located approximately at the edge of the main body base 6000 connected to the self-cleaning dust collection holder bottom plate 1000. The dust collection opening 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 cavity 2100 of the self-cleaning dust collection holder 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 to connect and seal the dust collection opening 6100 and the dust outlet of the automatic cleaning device and prevent debris from leaking.

[0023] 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 debris removed from the wet cleaning module, and / or to collect wastewater generated during the cleaning process of the wet cleaning module, thereby making it easier to dispose of the 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 holder 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 cavity 2100. When the self-cleaning dust collection holder is in a dust collection state, a sufficient negative pressure is created in the dust collection bin 3000, and dust in the dust box 300 is sucked into the dust bag in the dust collection cavity 2100 through the dust collection port 6100 and the air duct.

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

[0026] Specifically, the end surfaces of the dust collecting cavity side walls may have an arc-shaped structure, and the height of the dust collecting cavity side walls gradually decreases along the direction of the arrow of the front-rear axis X, so that at the point where the dust collecting cavity side walls are adjacent to the dust collecting cavity rear wall 2134, the height of the dust collecting cavity side walls is equal to the height of the dust collecting cavity rear wall 2134. The dust collecting cavity side walls have an arc-shaped structure with a low front and a high rear, which can facilitate the installation and removal of the dust collecting cover 2800 and improve the aesthetics to a certain extent.

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

[0028] In some embodiments, the dust collection cavity 2100 further includes a circumferential inner wall 2150, which extends from a bottom wall of the dust collection cavity 2100 in a direction away from the cleaning dust collection holder body 2000. The dust collection cavity rear wall 2134 and the dust collection cavity side walls are disposed around the circumferential inner wall 2150 and are spaced apart from the circumferential inner wall 2150. The height of various parts of the circumferential inner wall 2150 may not be equal, 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-to-rear axis X, such that the front of the circumferential inner wall 2150 is lower and the rear of the circumferential inner wall 2150 is higher, which can facilitate placement and removal of the dust collection cover 2800.

[0029] In some embodiments, the circumferential inner wall 2150 may have a closed loop structure, and further includes 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 is disposed opposite the rear inner wall 2154, and the first side inner wall 2151 is disposed opposite the second side inner wall 2152. Each inner wall of the circumferential inner wall 2150 corresponds to the dust collection cavity rear wall 2134 and the dust collection cavity side wall. Specifically, the first side inner wall 2151 is disposed on the same side as the first dust collection cavity side wall 2131, the rear inner wall 2154 is disposed on the same side as the dust collection cavity rear wall 2134, and the second side inner wall 2152 is disposed on the same side as the second dust collection cavity side wall 2132.

[0030] In some embodiments, the inner circumferential wall 2150 may be integral with the bottom wall of the dust collection cavity 2100, thereby improving the stability of the inner circumferential wall 2150.

[0031] In some embodiments, the dust collection cavity 2100 further includes a seal gasket 2140, which is disposed around the circumferential inner wall 2150, and the dust collection cavity rear wall 2134 and the dust collection cavity side walls are disposed around the seal gasket 2140. In some embodiments, the seal gasket 2140 has a closed loop structure, and the width of each portion of the seal gasket 2140 is equal to or slightly greater than the distance between the circumferential inner wall 2150 and the dust collection cavity rear wall 2134 and the dust collection cavity side walls. Therefore, the seal gasket 2140 is tightly connected to the circumferential inner wall 2150, the dust collection cavity rear wall 2134, and the dust collection cavity side walls. The material of the seal gasket 2140 may be various natural or artificial synthetic rubbers. The sealing gasket 2140 allows the dust collection cavity 2100 to seal against the dust collection cover 2800 coupled to the dust collection cavity 2100 to form a sealed dust collection bin 3000 .

[0032] In some embodiments, a dust bag support 2110 is further provided within the dust collection cavity 2100, and the dust bag support 2110 is configured to attach a dust bag. The dust bag support 2110 is provided inside the dust collection cavity 2100 and extends from the bottom of the dust collection cavity in a direction away from the self-cleaning dust collection holder body 2000. The dust bag support 2110 is provided on a circumferential inner wall 2150 of the dust collection cavity 2100 by a fastening member such as a screw, or is fixedly connected to the bottom wall of the dust collection cavity via the bottom of the dust bag support 2110. In some embodiments, the dust bag support 2110 is provided on a first side inner wall 2151, and the side wall of the dust bag support 2110 away from the dust collection cavity 2100 may be integrally formed with the first side inner wall 2151, which can improve the robustness of the dust bag support 2110. A hollow cavity is provided inside the dust bag support 2110, and the hollow cavity functions as a part of an air duct of the self-cleaning dust collection holder, for example, an end of the air duct. The dust bag support 2110 has a support side wall facing the inside of the dust collection bin 3000, and a dust outlet port is provided on the support side wall, and the dust outlet port communicates with the dust collection mouth 6100 through an air duct, and the air duct is used to guide dust into the dust collection bin 3000, for example, to a dust bag in the dust collection bin 3000. The dust outlet port is configured to communicate with the inlet of the dust bag to collect dust in the dust bag.

[0033] 4 and 5 , in some embodiments, the dust collection cover 2800 includes a dust collection cover body 2810 and a dust collection cover wall 2820. Here, the dust collection cover body 2810 is positioned above the dust collection cover wall 2820, and the dust collection cover wall 2820 extends in a direction away from the dust collection cover body 2810. The dust collection cover body 2810 and the dust collection cover wall 2820 enclose an accommodating space, and in response to the dust collection cover 2800 being locked onto the dust collection cavity 2100, the circumferential inner wall 2150 is received within the accommodating space, and the free end of the dust collection cover wall 2820 away from the dust collection cover body 2810 is in close contact with the sealing gasket 2140 to form a sealed dust collection bin 3000.

[0034] 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, connected in sequence, where 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.

[0035] In response to the dust collection cover 2800 being coupled to the dust collection cavity 2100, at least a portion of the dust collection cover first side wall 2821 is sandwiched between the first dust collection cavity side wall 2131 and the first side inner wall 2151, at least a portion of the dust collection cover second side wall 2822 is sandwiched between the second dust collection cavity side wall 2132 and the second side inner wall 2152, and the dust collection cover rear wall 2824 is sandwiched between the dust collection cavity rear wall 2134 and the rear inner wall 2154.

[0036] In some embodiments, the dust collection cover 2800 further includes a pull handle 2811, which is provided on a side of the dust collection cover body 2810 away from the dust collection cover wall 2820. The pull handle 2811 may be a structure such as a pull ring, pull rod, or handle provided on the dust collection cover body 2810, and the provision of the pull handle 2811 may make it easier to place and remove the dust collection cover 2800, which may make it more convenient for a user to replace the debris in the dust collection bin 3000 on a daily basis.

[0037] In some embodiments, the dust collection cover 2800 further includes 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 cavity 2100, so that the dust collection cover 2800 is firmly fixed on the dust collection cavity 2100 without shaking. The restricting portion is provided on at least one of the dust collection cavity rear wall 2134 and the dust collection cavity side wall. The restricting member 2825 and the restricting portion are provided in pairs and aligned with each other. In the embodiment shown in FIG. 4 , the restricting member 2825 is provided on the dust collection cover second side wall 2822, and a restricting portion corresponding to the restricting member 2825 is provided on the second dust collection cavity side wall 2132. In response to the dust collection cover 2800 being locked into the dust collection cavity 2100, the restricting member 2825 abuts against the restricting portion.

[0038] In some embodiments, support ribs 2826 are provided on at least one of the dust collection cavity bottom wall, the inner circumferential wall 2150, and the dust collection cover wall 2820. The support ribs 2826 may be strip-like structures that protrude outward from the surface.

By providing the support ribs 2826, it is possible to prevent the dust bag in the dust collection bin 3000 from coming into close contact with the dust collection cavity bottom wall, the inner circumferential wall 2150, and / or the dust collection cover wall 2820, which would affect the outflow of airflow from the dust bag.

[0039] The present disclosure further provides a dust collection system including an automatic cleaning device and the self-cleaning dust collection holder in the above embodiment.

[0040] The design of the dust collection cover being coupled onto the dust collection cavity allows the dust collection cover to be more closely coupled to the dust collection cavity under the action of the fan, further improving dust collection efficiency; the exposed design of the dust collection cover makes it easier for users to intuitively observe the situation inside the cover, facilitating more timely handling of the dust collection cavity, such as replacing the dust bag.

[0041] In the related art, the dust box of an automatic cleaning device has limited capacity, and users have to bend down frequently to clean the dust box, which causes a poor user experience. Therefore, an embodiment of the present disclosure provides a self-cleaning dust collection holder, in which dust in the dust box of the automatic cleaning device is concentrated and collected in a dust collection bin of the self-cleaning dust collection holder by a dust collection system, and the dust collection bin is provided with a dust bag support and a dust bag, so that the dust in the dust box is transferred to the dust bag in the dust collection bin with virtually no 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 a locking plate and a sliding plate, and when the dust bag is detached from the dust bag support, the sliding plate is in a closed position, so that the dust in the dust bag will not spill into the dust collection bin.

[0042] Specifically, the self-cleaning dust collection holder provided by the embodiments of the present disclosure includes, for example, FIG. 1 exemplarily shows a schematic diagram of the overall structure of the self-cleaning dust collection holder, and FIG. 2 exemplarily shows a schematic diagram of the structure of the self-cleaning dust collection holder body after the dirty water tank, clean water tank, and dust collection cover of the present disclosure have been removed.

[0043] As shown in FIG. 1 , the direction in which the self-cleaning dust collection holder bottom plate 1000 protrudes from the self-cleaning dust collection holder main body 2000 is the front, the direction toward the rear wall of the self-cleaning dust collection holder main body 2000 is the rear, the dust collection bin 3000 is on the left side of the self-cleaning dust collection holder, the clean water tank 4000 is on the right side of the dust collection bin 3000, and the dirty water tank 5000 is on the right side of the clean water tank 4000.

Specifically, the self-cleaning dust collection holder bottom plate 1000 and the body base 6000 are sequentially arranged along a second direction, which is opposite to the arrow of the front-rear axis X.

[0046] The dust collection opening 6100 is provided on the main body base 6000, and is provided at approximately the edge position of the main body base 6000 connected to the self-cleaning dust collection holder bottom plate 1000. The dust collection opening 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 cavity 2100 of the self-cleaning dust collection holder 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 connect and seal the dust collection opening 6100 and the dust outlet of the automatic cleaning device and prevent debris from leaking.

[0047] 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 and is used, for example, to replenish cleaning fluid in the wet cleaning module of the automatic cleaning device, and / or to accommodate debris removed from the wet cleaning module, and / or to collect wastewater generated during the process of cleaning the wet cleaning module, thereby making it easier to dispose of the debris 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 collection holder 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 cavity 2100. When the self-cleaning dust collection holder is in a dust collection state, a sufficient negative pressure is created in the dust collection bin 3000, and dust in the dust box 300 is sucked into the dust bag in the dust collection cavity 2100 through the dust collection port 6100 and the air duct.

[0049] FIG. 6 is a structural schematic diagram of a dust bag support provided by some embodiments of the present disclosure, where the sliding baffle is in a first position, and FIG. 7 is a structural schematic diagram of a dust bag support provided by some embodiments of the present disclosure, where the sliding baffle is in a second position.

[0050] 1 and 2, in some embodiments, the self-cleaning dust collection holder further includes a dust bag support 2110, which is configured to attach a dust bag. The dust bag support 2110 is attached to the dust collection bin 3000, and is attached to the inner wall of the dust collection bin 3000 by a fastening member such as a screw, or is fixedly connected to the bottom surface of the dust collection bin 3000 via the bottom of the dust bag support 2110.

[0051] A hollow cavity is provided inside the dust bag support 2110, which serves as a part of the air duct of the self-cleaning dust collection holder, for example, the end of the air duct.

[0052] The dust bag support 2110 has a support side wall 2111 facing the inside of the dust collection bin 3000, and a dust outlet port 2112 is provided on the support side wall 2111. The dust outlet port 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 port 2112 is configured to communicate with the inlet of a dust bag to collect dust in the dust bag.

[0053] The dust bag support 2110 further includes a sliding baffle 2113 that is slidable on the support side wall 2111. The sliding baffle 2113 is configured to be switchable between a first position and a second position. In response to the sliding baffle 2113 being in the first position, the sliding baffle 2113 blocks the dust outlet port 2112, and in response to the sliding baffle 2113 being in the second position, the sliding baffle 2113 exposes the dust outlet port 2112. A dust bag is a consumable item and is removably attached to the dust bag support 2110. With the above design, when no dust bag is attached to the dust bag support 2110, the sliding baffle 2113 blocks the dust outlet port 2112 to isolate the dust collection bin 3000 from the air duct, so that the suction force generated by the fan cannot enter the air duct from the dust collection bin, and dust can be prevented from entering the dust collection bin 3000 without a dust bag attached.

[0054] FIG. 8 is a structural schematic diagram of a dust bag provided by some embodiments of the present disclosure, with the sliding plate in a closed position; FIG. 9 is a structural schematic diagram of a dust bag provided by some embodiments of the present disclosure, with the sliding plate in an open position; FIG. 9A is a partial structural schematic diagram of a dust bag provided by some embodiments of the present disclosure; FIG. 9B is a structural schematic diagram of a cross section in FIG. 9A, with the cross section of the dust bag shown in FIG. 9A and the dust bag 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 configured to be removably attached to the dust bag support 2110 to collect dust.

[0056] The dust bag 2120 includes a dust bag body 2121, a latch plate 2122, and a sliding plate 2123. The dust bag body 2121 is made of a breathable material such as nonwoven fabric or paper that can filter fine particles, and is configured to accommodate the dust. The latch plate 2122 is fixedly connected to the dust bag body 2121. The latch plate 2122 has a latch plate opening 21221, which serves as an entrance to the dust bag body 2121. The sliding plate 2123 is slidably connected to the locking plate 2122 and is configured to be switchable between a closed position and an open position, and in response to the sliding plate 2123 being in the closed position, the sliding plate 2123 covers the locking plate opening 21221, and in response to the sliding plate 2123 being in the open position, the sliding plate 2123 exposes the locking plate opening 21221.

[0057] 8 and 6, the sliding plate 2123 has a sliding plate opening 21231, and as shown in Fig. 8, when the sliding plate 2123 is in the closed position, the orthogonal projection of the sliding plate opening 21231 on the locking plate 2122 does not overlap with the locking plate opening 2821, and the sliding plate 2123 shields the locking plate opening 22121. As shown in Fig. 9, when the sliding plate 2123 is in the open position, the orthogonal projection of the sliding plate opening 21231 on the locking plate 2122 at least partially overlaps with the locking plate opening 21221, and the sliding plate 2123 exposes at least a portion of the locking plate opening 21221 through the sliding plate opening 21231.

[0058] In some embodiments, the size of the sliding plate opening 21231 is, for example, larger than the locking plate opening 21221, such that, in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 on the locking plate 2122 covers the locking plate opening 21221. In some embodiments, the size of the sliding plate opening 21231 is, for example, smaller than the locking plate opening 21221, such that, in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 on the locking plate 2122 is located within the locking plate opening 21221. In some embodiments, the size of the sliding plate opening 21231 is, for example, equal to the locking plate opening 21221, such that, in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 on the locking plate 2122 essentially overlaps with the locking plate opening 21221.

[0059] The sliding movement of the sliding plate 2123 and the locking plate 2122 blocks the entrance to the dust bag, 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 is provided on the edge of the locking plate opening 21221, protruding towards the sliding plate 2123, and in response to the sliding plate 2123 being in the open position, the flexible rubber ring 21224 protrudes through the sliding plate opening 21231 in a direction away from the sliding plate 2123, and when the sliding plate opening 21231 is connected to the locking plate opening 21221, it seals the slits at the connection points of both the sliding plate 2123 and the locking plate 2122 openings, thereby sealingly connecting the sliding plate opening 21231 to the locking plate opening 21221. In response to the sliding plate 2123 not being 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 locking plate 2122, increasing the frictional force between them, so that the sliding plate 2123 and the locking plate 2122 will not 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 dust from leaking from the dust bag.

[0061] As described above, due to the sliding design of the locking plate 2122 and the sliding plate 2123 in the dust bag, the sliding plate 2123 is slidably connected to the locking plate 2122 and is configured to be switchable between a closed position and an open position, sealing or exposing the entrance of the dust bag, and when the entrance of the dust bag is sealed, leakage of dust in the dust bag can be prevented.

[0062] The flexible rubber ring 21224 provided on the edge of the locking plate opening 21221 ensures good sealing performance between the dust bag and the dust outlet port 2112, further improving dust collection efficiency and preventing dust from falling out of the gap between the dust outlet port 2112 and the locking plate 2122, and between the locking plate 2122 and the sliding plate 2123 during the dust collection process, thereby contaminating the dust collection cavity, thereby reducing the user's maintenance workload for the dust collection cavity and improving the user experience.

[0063] 8 and 9, in some embodiments, the sliding plate 2123 is slidable relative to the locking plate 2122 in a first direction M, and the sliding plate 2123 includes limiting bump blocks 21243 provided on at least one side of the sliding plate 2123, for example, on both sides of the sliding plate 2123. The limiting bump blocks 21243, for example, two in number, protrude from the sliding plate 2123 in a second direction perpendicular to the first direction M. The locking plate 2122 includes limiting members 21223 provided on both ends of the locking plate 2122 in the first direction and configured to block the limiting bump blocks 21233 in the first direction M and prevent the sliding plate 2123 from separating from the locking plate 2122. The limiting members 21223 are, for example, four in number, and are distributed symmetrically on both sides of the locking plate 2122. When the sliding plate 2123 slides relative to the locking plate 2122, the limiting bump blocks 21233 can only move between the corresponding limiting members 21223 at both ends of the locking plate 2122 in the first direction.

[0064] In some embodiments, the sliding plate 2123 includes a handle portion 21232 provided at one end of the sliding plate in the first direction M and configured to be grasped by an operator to facilitate moving the sliding plate 2123.

[0065] The dust bag 2120 is configured to be detachably mounted on the dust bag support 2110, and in response to the dust bag 2120 being mounted on the dust bag support 2110, the sliding baffle 2123 is in the second position to expose the dust outlet port, the sliding plate is in the open position, and the locking plate opening 21221 is connected to the dust outlet port 2112. With the above-mentioned arrangement, when the dust bag 2120 is not mounted on the dust bag support 2110, the sliding baffle 2113 is in the first position to block the dust outlet port 2112, so that the suction force generated by the fan cannot enter the air duct from the dust collection bin, and thus it is possible to prevent dust from entering the dust collection bin 3000 to which the dust bag 2120 is not mounted.

[0066] When the dust bag 2120 is detached from the dust bag support 2110, the sliding plate 2123 is in the closed position to prevent the dust in the dust bag from leaking into the dust collection bin. The closed dust bag can prevent the dust in the dust bag from leaking into the external environment.

[0067] When the dust bag 2120 is not attached to the dust bag support 2110, its sliding plate 2123 covers the locking plate opening 21221 of the locking plate 2122; when it is attached to the dust bag support 2110, the sliding plate 2123 and the locking plate 2122 work together to push the sliding baffle 2113 from the first position to the second position and fix it in the second position; when the dust bag 2120 is detached from the dust bag support 2110, its sliding plate 2123 covers the locking plate opening 21221 to prevent dust leakage. When the dust bag 2120 is not attached to the dust bag support 2110, the locking plate opening 21221 (i.e., the dust bag inlet) is connected to the dust outlet port 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 in the dust bag body 2121 sequentially through the dust collection port 6100 on the main body base 6000, the air duct in the self-cleaning dust collection holder, the dust outlet port 2112 on the dust bag support 2110 and the locking plate opening 21221 on the dust bag 2120.

[0068] FIG. 10 is a schematic diagram of a pre-assembled dust bag support and a dust bag provided by some embodiments of the present disclosure, and FIG. 11 is a schematic diagram of an assembled structure of a dust bag support and a dust bag provided by some embodiments of the present disclosure.

[0069] 6 to 11, the dust bag support 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. 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 support side wall 2111 of the dust bag support 2110, respectively, and the two sliding grooves 2114 respectively receive opposite ends of the sliding baffle 2113, and the sliding baffle 2113 slides along the extension direction X' of the sliding groove 2114.

[0070] 6 to 11, the locking 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, so that the dust bag 2120 is mounted on the dust bag support body 2110. Specifically, both ends of the locking plate 2122 and the sliding plate 2123 of the dust bag 2120 are inserted into the two sliding grooves 2114, respectively. In response to the dust bag 2120 being mounted on the dust bag support 2110, the sliding plate 2123 is in an open position, exposing the locking plate opening 21221, the sliding baffle 2113 is in a second position, exposing the dust outlet port 2112, and the locking plate opening 21221 is connected to the dust outlet port 2112.

[0071] 10 , during the process of attaching the dust bag 2120 to the dust bag support 2110, the dust bag 2120 moves relative to the dust bag support 2110 along the extension direction X′ of the sliding groove 2114. When the two are attached, the locking plate 2122 and the sliding plate 2123 of the dust bag 2120 face the support side wall 2111 of the dust bag support 2110, and during the process of inserting the locking plate 2122 and the 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.

[0072] 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 facing the dust collection bin 3000 along the lower edge of the sliding baffle 2113. After the sliding plate 2123 is inserted into the sliding groove 2114, the lower end of the sliding plate 2123 can abut 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 push the sliding baffle 2113 to slide in the same manner 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, and the sliding plate protrusion 21233 is a strip-shaped protrusion facing the dust collection bin 3000 along the lower edge of the sliding plate 2123. 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 due to the abutting sliding plate protrusion 21233 and sliding baffle protrusion 21131, it pushes the sliding baffle 2113 and slides in the same manner along the extension direction X' of the sliding groove.

[0073] FIG. 11 shows a cross-sectional view of an assembly structure of a dust bag support and a dust bag provided by some embodiments of the present disclosure, and FIG. 12 shows a schematic diagram of an assembly structure of a dust bag support and a dust bag provided by some embodiments of the present disclosure.

[0074] 11 and 12, a locking portion 21141, such as an elastic buckle, is provided in the sliding groove 2114, and moves in an approximately arc-like manner as indicated by the arrow in FIG. 12. The locking plate 2122 has a locking plate locking groove 21222 that fits with the locking portion 21141, and the locking portion 21141 is locked into the locking plate locking groove 21222 in response to the dust bag 2120 being mounted on the dust bag support 2110. The locking plate 2122 slides along the extending direction X' of the sliding groove 2114 to a locking position, and the locking plate opening 21221 is connected to the dust outlet port 2112, and the locking portion 21141 is fitted into and locked into the locking plate locking groove 21222, thereby fixing the dust bag 2120 on the dust bag support 2110.

[0075] The limiting bump block 212234 on the sliding plate 2123 also functions as an unlocking bump block 21234, and is referred to as an unlocking bump block 21234. When the sliding plate 2123 is being pulled away from the locking groove 2114, the limiting bump block 212234 presses the locking portion 21141 to disengage the locking portion 21141 from the locking plate locking groove 21222, thereby releasing the locking portion 21141 from the locking plate locking groove 21222, and allowing the dust bag 2120 to be smoothly released from the dust bag support body 2110. In some embodiments, the unlocking bump block 21234 also has a limiting function, and cooperates with the limiting member 21223 on the locking plate 2122 to prevent the sliding plate 2123 from being released from the locking plate 2122.

[0076] 13 , the dust bag support 2110 is provided with an elastic member 2115, such as a spring. The elastic member 2115 is connected to the sliding baffle 2113 and biases the sliding baffle 2113 to 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 port 2112. In some embodiments, the elastic member 2115 is located inside the dust bag support 2110, and the extension direction of the elastic member 2115 basically coincides with the extension direction of the sliding groove 2114, and one end of the elastic member 2115 is fixed to the top of the dust bag support 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 are provided at opposite ends of the dust bag support 2110, respectively.

[0077] The process of attaching and detaching the dust bag 2120 and the dust bag support 2110 will now be described in detail.

[0078] When no dust bag 2120 is attached to the dust bag support 2110, the sliding baffle 2113 on the dust bag support 2110 is in a first position, blocking the dust outlet port 2112, and the sliding plate 2123 on the dust bag 2120 is in a closed position, blocking the locking plate opening 2122, i.e., the state shown in FIG. 8. When the dust bag 2120 is attached to the dust bag support 2110, the locking 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 locking plate 2122, and the sliding plate opening 21231 on the sliding plate 2123 is aligned with the locking plate opening 21221 on the locking plate 2122. At the same time, the locking plate 2122 and the sliding plate 2123 push the sliding baffle 2113 to move it from the first position to the second position, thereby causing the sliding baffle 2113 to expose the dust outlet port 2112. When the locking plate 2122 slides to the locking position along the extension direction X' of the sliding groove 2114, the locking plate opening 21221 is connected to the dust outlet port 2112, and the locking part 21141 fits into the locking groove 21222 and locks, thereby fixing the dust bag 2120 on the dust bag support body 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 port 2112, and the locking plate opening 21221 of the dust bag is sealably connected to the dust outlet port 2112 of the dust bag support body, thereby preventing dust leakage during the dust collection process.

[0079] During the process of removing the dust bag 2120 from the dust bag support 2110, an operator grasps the handle 21232 of the sliding plate 2123 and gradually pulls the sliding plate 2123 away from the sliding groove 2114 of the dust bag support 2110. During this process, the sliding plate 2123 gradually moves from the open position to the closed position relative to the locking plate 2122, so that the sliding plate 2123 covers the locking plate opening 21221, and the unlocking bump block 21234 on the sliding plate 2123 presses the locking portion 21141 to move the locking portion 21141 into the locking groove 21222. and at the same time, due to the interaction between the unlocking bump block 21234 and the limiting member 21223 on the locking plate 2122, the handle portion 21232 of the sliding plate 2123 is further pulled out, causing the sliding plate 2123 and the locking plate 2122 to be pulled out from the sliding groove 2114 of the dust bag support 2110, so that the dust bag 2120 is released from the dust bag support 2110, and the sliding baffle 2113 returns to its first position under the action of the elastic member, and the sliding baffle 2113 covers the dust outlet port 2112.

[0080] The present disclosure further provides a dust collection system including an automatic cleaning device and the self-cleaning dust collection holder in the above embodiment.

[0081] The self-cleaning dust collection holder provided by the embodiments of the present disclosure uses a dust collection system to concentrate and collect the dirt in the dust box of the automatic cleaning device in the dust collection bin of the self-cleaning dust collection holder, and the dust collection bin is provided with a dust bag support and a dust bag, so that the dirt in the dust box is transferred to the dust bag in the dust collection bin with virtually no leakage, thereby reducing the number of times the user has to dispose of the dirt and improving the user experience.

[0082] 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.

[0083] The above embodiments are used to explain the technical solutions of the present disclosure, but are not intended to limit them.
