In some embodiments, a sealing gasket is further disposed around the dust collection port 6100 for sealing after the dust collection port 6100 is engaged with a dust outlet of the automatic cleaning device, thereby preventing waste leakage.

In some embodiments, the body base 6000 further includes a cleaning tank 6200, which is configured to clean to-be-cleaned components on the automatic cleaning device, for example, by supplementing a wet cleaning module of the automatic cleaning device with a cleaning solution, and/or housing debris removed from the wet cleaning module, and/or collecting waste water produced during cleaning of the wet cleaning module, thereby facilitating the subsequent treatment of the debris and waste water. In some embodiments, the cleaning tank 6200 is disposed behind the dust collection port 6100.

In some embodiments, the self-cleaning dust collection seat further includes an air duct. One end of the air duct is communicated with the dust collection port 6100 of the body base 6000, and the other end of the air duct is communicated with the dust collection chamber 2100. When the self-cleaning dust collection seat is in a dust collection state, a sufficient negative pressure is created in the dust collection bin 3000 to suck the waste from the dust box 300 into the dust bag in the dust collection chamber 2100 through the dust collection port 6100 and the air duct.

FIG. 6 shows a schematic structural diagram of a dust bag holder according to some embodiments of the present disclosure, with a sliding baffle in a first position; and FIG. 7 shows a schematic structural diagram of a dust bag holder according to some embodiments of the present disclosure, with the sliding baffle in a second position.

In combination with FIG. 1 and FIG. 2, in some embodiments, the self-cleaning dust collection seat further includes a dust bag holder 2110, which is configured for installation of the dust bag. The dust bag holder 2110 is disposed in the dust collection bin 3000, for example, disposed on an inner side wall of the dust collection bin 3000 by means of screws or other fixing components, or fixedly connected to a bottom surface of the dust collection bin 3000 through the bottom of the dust bag holder 2110.

A hollow cavity is provided inside the dust bag holder 2110, and the hollow cavity serves as part of the air duct of the self-cleaning dust collection seat, for example, as a tail end of the air duct.

The dust bag holder 2110 includes a holder side wall 2111 facing the inside of the dust collection bin 3000, and the holder side wall 2111 is provided with a dust outlet interface 2112. The dust outlet interface 2112 is communicated with the dust collection port 6100 through the air duct. The air duct is used to guide the waste into a body of the dust collection bin 3000, for example, into the dust bag in the body of the dust collection bin 3000. The dust outlet interface 2112 is configured to be communicated with an inlet of the dust bag and is used to collect the waste into the dust bag.

The dust bag holder 2110 further includes a sliding baffle 2113 that is slidable on the holder side wall 2111. The sliding baffle 2113 is configured to be switchable between the first position and the second position. In response to the sliding baffle 2113 being in the first position, the sliding baffle 2113 shields the dust outlet interface 2112; and in response to the sliding baffle 2113 being in the second position, the sliding baffle 2113 exposes the dust outlet interface 2112. The dust bag as a consumable may be detachably installed on the dust bag holder 2110. Before the dust bag is installed into the dust bag holder 2110, the dust bag holder with the design described above may allow the sliding baffle 2113 to shield the dust outlet interface 2112 to isolate the dust collection bin 3000 from the air duct, such that a sucking force produced by the fan cannot enter the air duct via the dust collection bin, preventing the waste from entering the dust collection bin 3000 without the dust bag being installed.

FIG. 8 shows a schematic structural diagram of a dust bag according to some embodiments of the present disclosure, with a sliding plate in a closed position: FIG. 9 shows a schematic structural diagram of the dust bag according to some embodiments of the present disclosure, with the sliding plate in an open position: FIG. 9A shows a partially schematic structural diagram of the dust bag according to some embodiments of the present disclosure; and FIG. 9B shows a schematic structural diagram of a section in FIG. 9A. Here, the section of the dust bag is shown in FIG. 9A, and the dust bag is not shown in FIG. 9 and FIG. 9B.

In some embodiments, as shown in FIG. 8 to FIG. 9B, the present disclosure further provides a dust bag 2120. The dust bag 2120 is configured to be detachably installed on a dust bag holder 2110 to collect waste.

The dust bag 2120 includes a dust bag body 2121, a clamping plate 2122, and a sliding plate 2123. The dust bag body 2121, for example, is made of a material that is breathable and may filter fine particles, for example, a non-woven fabric or a paper material, and the dust bag body is configured to receive the waste. The clamping plate 2122 is fixedly connected to the dust bag body 2121. The clamping plate 2122 has a clamping plate opening 21221, which serves as an inlet of the dust bag body 2121. The sliding plate 2123 is slidably connected to the clamping plate 2122, and is configured to switch between a closed position and an open position. The sliding plate 2123 shields the clamping plate opening 21221 in response to the sliding plate 2123 being in the closed position, and exposes the clamping plate opening 21221 in response to the sliding plate 2123 being in the open position.

Specifically, as shown in FIG. 8 and FIG. 6, the sliding plate 2123 has a sliding plate opening 21231. In response to the sliding plate 2123 being in the closed position, an orthographic projection of the sliding plate opening 21231 on the clamping plate 2122 does not overlap with the clamping plate opening 2821, and the sliding plate 2123 shields the clamping plate opening 22121, as shown in FIG. 8. In response to the sliding plate 2123 being in the open position, the orthographic projection of the sliding plate opening 21231 on the clamping plate 2122 at least partially overlaps with the clamping plate opening 21221, and the sliding plate 2123 exposes at least part of the clamping plate opening 21221 by means of the sliding plate opening 21231, as shown in FIG. 9.

In some embodiments, a size of the sliding plate opening 21231 is for example larger than that of the clamping plate opening 21221, and in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 on the clamping plate 2122 covers the clamping plate opening 21221. In some embodiments, a size of the sliding plate opening 21231 is for example smaller than that of the clamping plate opening 21221, and in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 on the clamping plate 2122 falls within the clamping plate opening 21221. In some embodiments, the size of the sliding plate opening 21231 is for example equal to that of the clamping plate opening 21221, and in response to the sliding plate 2123 being in the closed position, the orthographic projection of the sliding plate opening 21231 on the clamping plate 2122 substantially coincides with the clamping plate opening 21221.

By means of the sliding fit between the sliding plate 2123 and the clamping plate 2122, an inlet of the dust bag can be closed to avoid the leakage of waste from the dust bag.

In some embodiments, as shown in FIG. 8 to FIG. 9B, the edge of the clamping plate opening 21221 is provided with a flexible rubber ring 21224 that protrudes towards the sliding plate 2123. In response to the sliding plate 2123 being in the open position, the flexible rubber ring 21224 protrudes through the sliding plate opening 21231 towards a direction away from the sliding plate 2123, such that when the sliding plate opening 21231 and the clamping plate opening 21221 are engaged, a slit between the sliding plate 2123 and the clamping plate 2122 at the joint of the two openings is blocked, such that the sliding plate opening 21231 and the clamping plate opening 21221 are sealedly engaged. In response to the sliding plate 2123 being not in the open position, for example, being in the closed position, at least part of the flexible rubber ring 21224 may be squeezed between the sliding plate 2123 and the clamping plate 2122 to increase a friction force therebetween, such that the sliding plate 2123 and the clamping plate 2122 can slide relative to each other only under the action of an external force, allowing for stably keeping the sliding plate 2123 in the closed position to avoid the littering of waste from the dust bag.

In summary, the sliding design for the clamping plate 2122 and the sliding plate 2123 in the dust bag allows for the slidable connection between the sliding plate 2123 and the clamping plate 2122, and the sliding plate is configured to switch between the closed position and the open position to close or expose the inlet of the dust bag, such that the waste in the dust bag can be prevented from leakage in the case of closing the inlet of the dust bag.

The flexible rubber ring 21224 provided on the edge of the clamping plate opening 21221 ensures a good sealing performance between the dust bag and the dust outlet interface 2112, which can further improve the dust collection efficiency, and which also plays a role in preventing dust from falling out of a gap between the dust outlet interface 2112 and the clamping plate 2122 and a gap between the clamping plate 2122 and the sliding plate 2123 in a dust collection process to in turn pollute the dust collection chamber, thereby reducing the workload of the user in maintaining the dust collection chamber and improving the user experience.

In some embodiments, as shown in FIG. 8 and FIG. 9, the sliding plate 2123 is slidable in a first direction M relative to the clamping plate 2122. The sliding plate 2123 includes a position limiting bump 21234, which is disposed on at least one side of the sliding plate 2123, for example, on both sides of the sliding plate 2123, in which case the number of the position limiting bumps 21234 is 2, for example. The limiting bump protrudes from the sliding plate 2123 in a second direction perpendicular to the first direction M. The clamping plate 2122 includes position limiting components 21223, which are disposed on both ends of the clamping plate 2122 in the first direction, and are configured to block the position limiting bump 21233 in the first direction M, thereby preventing the sliding plate 2123 from being disengaged from the clamping plate 2122. The number of the position limiting components 21223 is 4, for example, and the limiting components are symmetrically distributed on both sides of the clamping plate 2122. When the sliding plate 2123 slides relative to the clamping plate 2122, the position limiting bump 21233 can only move between the corresponding position limiting components 21223 at both ends of the clamping plate 2122 in the first direction.

In some embodiments, the sliding plate 2123 further includes a handle 21232, which is disposed on an end of the sliding plate in the first direction M and is configured to facilitate an operator to hold and then move the sliding plate 2123.

The dust bag 2120 is configured to be detachably installed on the dust bag holder 2110. In response to the dust bag 2120 being installed on the dust bag holder 2110, the sliding baffle 2123 is in the second position to expose the dust outlet interface, the sliding plate is in the open position, and the clamping plate opening 21221 is engaged with the dust outlet interface 2112. Based on the configuration described above, before the dust bag 2120 is installed into the dust bag holder 2110, the sliding baffle 2113 of the dust bag holder is in the first position to shield the dust outlet interface 2112, such that the sucking force produced by the fan cannot enter the air duct via the dust collection bin, preventing the waste from entering the dust collection bin 3000 without the dust bag 2120 being installed.

When the dust bag 2120 is disassembled from the dust bag holder 2110, the sliding plate is in the closed position 2123, thereby preventing the waste in the dust bag from being littered in the dust collection bin. Moreover, the sealed dust bag also prevents the waste in the dust bag from being littered in the external environment.

Before the dust bag 2120 is installed into the dust bag holder 2110, the sliding plate 2123 shields the clamping plate opening 21221 of the clamping plate 2122, such that when the dust bag is installed into the dust bag holder 2110, the sliding baffle 2113 can be pushed from the first position to the second position and fixed in the second position by means of the joint action of the sliding plate 2123 and the clamping plate 2122; and when the dust bag 2120 is pulled away from the dust bag holder 2110, the sliding plate 2123 shields the clamping plate opening 21221 to avoid waste leakage. After the dust bag 2120 is installed into the dust bag holder 2110, the clamping plate opening 21221 (i.e., the inlet of the dust bag) is engaged with the dust outlet interface 2112, and the waste in the dust box of the automatic cleaning device may be collected into the dust bag body 2121 through the dust collection port 6100 in the body base 6000, the air duct inside the self-cleaning dust collection seat, the dust outlet interface 2112 on the dust bag holder 2110, and the clamping plate opening 21221 in the dust bag 2120 in sequence under the action of an airflow provided by the fan.

FIG. 10 shows a schematic diagram of a pre-assembled structure of a dust bag holder and a dust bag according to some embodiments of the present disclosure; and FIG. 11 shows a schematic diagram of an assembled structure of a dust bag holder and a dust bag according to some embodiments of the present disclosure.

In some embodiments, as shown in FIG. 6 to FIG. 11, the dust bag holder 2110 includes a sliding chute 2114, and at least part of the sliding baffle 2113 is located in the sliding chute 2114, such that the sliding baffle 2113 may slide in an extension direction X′ of the sliding chute 2114, and then switch between the first position and the second position. For example, the number of the sliding chute 2114 is one or more. As shown in FIG. 6 to FIG. 11, the number of the sliding chute 2114 is 2, for example, in which case the sliding chutes are disposed on two opposite ends of a holder side wall 2111 of the dust bag holder 2110 respectively, and receive two opposite ends of the sliding baffle 2113, respectively, such that the sliding baffle 2113 may slide in the extension direction X′ of the sliding chute 2114.

As shown in FIG. 6 to FIG. 11, the clamping plate 2122 and the sliding plate 2123 of the dust bag 2120 are configured to be insertable into the sliding chute 2114, to slide in the extension direction X′ of the sliding chute 2114, and to push the sliding baffle 2113 to slide in the extension direction X′ of the sliding chute, allowing for the installation of the dust bag 2120 on the dust bag holder 2110. Specifically, both ends of the clamping plate 2122 and the sliding plate 2123 of the dust bag 2120 may be inserted into the two sliding chutes 2114 described above, respectively. In response to the dust bag 2120 being installed on the dust bag holder 2110, the sliding plate 2123 is in the open position to expose the clamping plate opening 21221, and the sliding baffle 2113 is in the second position to expose the dust outlet interface 2112, such that the clamping plate opening 21221 is engaged with the dust outlet interface 2112.

As shown in FIG. 10, during the process of installing the dust bag 2120 on the dust bag holder 2110, the dust bag 2120 moves in the extension direction X′ of the sliding chute 2114 relative to the dust bag holder 2110. When they are installed, the clamping plate 2122 and the sliding plate 2123 of the dust bag 2120 face the holder side wall 2111 of the dust bag holder 2110; and during the process of inserting the clamping plate 2122 and the sliding plate 2123 into the sliding chute 2114 in the extension direction X′ of the sliding chute 2114, the sliding baffle 2113 may be pushed to move from the first position to the second position.

In some embodiments, a lower end of the sliding baffle 2113 is provided with a sliding baffle protrusion 21131, which is a strip-like protrusion along a lower edge of the sliding baffle 2113 towards the dust collection bin 3000. After the sliding plate 2123 is inserted into the sliding chute 2114, a lower end of the sliding plate 2123 may be abutted against the sliding baffle protrusion 21131. The mutual abutting between the lower end of the sliding plate 2123 and the sliding baffle protrusion 21131 allows the sliding plate 2123, when sliding downwards in the extension direction X′ of the sliding chute 2114, to push the sliding baffle 2113 to slide in the extension direction X′ of the sliding chute together. In some embodiments, the lower end of the sliding plate 2123 is further provided with a sliding plate protrusion 21233, which is a strip-like protrusion along the lower edge of the sliding plate 2123 towards the dust collection bin 3000. After the sliding plate 2123 is inserted into the sliding chute 2114, the sliding plate protrusion 21233 may be just abutted against the upper side of the sliding baffle protrusion 21131. The mutual abutting between the sliding plate protrusion 21233 and the sliding baffle protrusion 21131 allows the sliding plate 2123, when sliding downwards in the extension direction X″ of the sliding chute 2114, to push the sliding baffle 2113 to also slide in the extension direction X″ of the sliding chute together.

FIG. 11 shows a sectional view of an assembled structure of a dust bag holder and a dust bag according to some embodiments of the present disclosure, and FIG. 12 shows a schematic diagram of an assembled structure of a dust bag holder and a dust bag according to some embodiments of the present disclosure.

In combination with FIG. 11 and FIG. 12, a snap fastener 21141. e.g., an elastic snap fastener, is disposed in the sliding chute 2114, and the snap fastener may move approximately in an arc as shown by an arrow in FIG. 12. The clamping plate 2122 has a clamping plate slot 21222 matching the snap fastener 21141; and in response to the dust bag 2120 being installed on the dust bag holder 2110, the snap fastener 21141 is clamped in the clamping plate slot 21222. The clamping plate 2122 slides to a clamping position in the extension direction X′ of the sliding chute 2114. The clamping plate opening 21221 is engaged with the dust outlet interface 2112; and the snap fastener 21141 matches and is clamped with the clamping plate slot 21222, such that the dust bag 2120 is fixed on the dust bag holder 2110.

A position limiting bump 212234 on the sliding plate 2123 also acts as, or is called, an unlocking bump 21234, which is configured such that during the process of pulling the sliding plate 2123 away from the slot 2114, the snap fastener 21141 is squeezed to enable disengagement of the snap fastener 21141 from the clamping plate slot 21222, thereby releasing the fixing of the snap fastener 21141 to the clamping plate 2122, and smoothly disengaging the dust bag 2120 from the dust bag holder 2110. In some embodiments, the unlocking bump 21234 also has a position limiting effect, and cooperates with a position limiting component 21223 on the clamping plate 2122 to prevent the sliding plate 2123 from disengagement from the clamping plate 2122.

In some embodiments, as shown in FIG. 13, the dust bag holder 2110 is provided with an elastic component 2115, e.g., a spring. The elastic component 2115 is connected to the sliding baffle 2113 and is configured such that the sliding baffle 2113 has a tendency to be in the 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 component 2115, such that the sliding baffle 2113 shields the dust outlet interface 2112. In some embodiments, the elastic component 2115 is located inside the dust bag holder 2110; an extension direction of the elastic component 2115 is basically the same as an extension direction of the sliding chute 2114; and one end of the elastic component 2115 is fixed on the upper part of the dust bag holder 2110, and the other end of the elastic component is connected to the sliding baffle 2113. The number of the elastic component 2115 is one or more, e.g., 2, in which case the two elastic components may be disposed on two opposite ends of the dust bag holder 2110, respectively.

The following specifically describes the process of installing and disassembling the dust bag 2120 and the dust bag holder 2110.

Before the dust bag 2120 is installed into the dust bag holder 2110, the sliding baffle 2113 on the dust bag holder 2110 is located in the first position to shield the dust outlet interface 2112, and the sliding plate 2123 on the dust bag 2120 is located in the closed position to shield the clamping plate opening 2122, such as in a state shown in FIG. 8. During the process of installing the dust bag 2120 into the dust bag holder 2110, the clamping plate 2122 and the sliding plate 2123 are inserted into the sliding chute 2114 in the extension direction X′ of the sliding chute 2114; and during the process in which a user holds the handle 21232 of the sliding plate 2123 and pushes the dust bag 2120 into the sliding chute 2114, the sliding plate 2123 gradually moves from the closed position to the open position relative to the clamping plate 2122, such that the sliding plate opening 21231 in the sliding plate 2123 is aligned with the clamping plate opening 21221 in the clamping plate 2122, and at the same time, the clamping plate 2122 and the sliding plate 2123 push against the sliding baffle 2113 to move from the first position to the second position, allowing the sliding baffle 2113 to expose the dust outlet interface 2112. When the clamping plate 2122 slides to a clamping position in the extension direction X′ of the sliding chute 2114, the clamping plate opening 21221 is engaged with the dust outlet interface 2112, and the snap fastener 21141 matches and is clamped with the slot 21222, such that the dust bag 2120 is fixed on the dust bag holder 2110. At this point, the flexible rubber ring 21224 on the dust bag is abutted against an edge of the dust outlet interface 2112 through the sliding plate opening 21231, such that the clamping plate opening 21221 of the dust bag is sealedly engaged with the dust outlet interface 2112 of the dust bag holder, avoiding waste leakage during the process of dust collection.

During the process of disassembling the dust bag 2120 from the dust bag holder 2110, an operator holds the handle 21232 of the sliding plate 2123 and gradually pulls the sliding plate 2123 away from the sliding chute 2114 of the dust bag holder 2110. In this process, the sliding plate 2123 gradually moves from the open position to the closed position relative to the clamping plate 2122, such that the sliding plate 2123 shields the clamping plate opening 21221, and the unlocking bump 21234 on the sliding plate 2123 extrudes the snap fastener 21141 to disengage the snap fastener 21141 from the slot 21222. At the same time, due to the interaction between the unlocking bump 21234 and the position limiting component 21223 on the clamping plate 2122, the handle 21232 of the sliding plate 2123 is continuously pulled to pull out the sliding plate 2123 and the clamping plate 2122 from the sliding chute 2114 of the dust bag holder 2110, and the dust bag 2120 is disengaged from the dust bag holder 2110. Under the action of the elastic component, the sliding baffle 2113 returns to the first position, such that the sliding baffle 2113 shields the dust outlet interface 2112.

The present disclosure further provides a dust collection system, including an automatic cleaning device and the self-cleaning dust collection seat in the foregoing embodiments.

According to the self-cleaning dust collection seat provided by the embodiments of the present disclosure, waste in the dust box of the automatic cleaning device is centralized and collected into the dust collection bin of the self-cleaning dust collection seat by means of the dust collection system, and the waste in the dust box is transferred into the dust bag in the dust collection bin in a substantially leakless way by means of the dust bag holder and the dust bag that are disposed in the dust collection bin, such that the number of times for a user to dispose the waste can be reduced, leading to improved user experience.

Finally, it should be noted that the embodiments in the specification are described in a progressive manner, with each embodiment focusing on its difference from other embodiments, and cross reference may be made for the same or similar sections between the embodiments.

The above embodiments are for the purpose of illustrating the technical solutions of the present disclosure only, and are not intended to limit the present disclosure. Although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that, they can still make modifications to the technical solutions described in the foregoing embodiments, or make equivalent substitutions to some of the technical features.
