The cleaning tank 6200 is configured to clean cleaning components on the automatic cleaning device, for example, to replenish a wet cleaning module of the automatic cleaning device with a cleaning fluid, and/or to accommodate sundries removed from the wet cleaning module, and/or to collect sewage generated in the process of cleaning the wet cleaning module, so as to facilitate subsequent treatment of the sundries and sewage. In some embodiments, the cleaning tank 6200 is arranged behind the dust collection port 6100.

In some embodiments, the self-cleaning dust collection seat further includes an air duct, one end of which is in communication with the dust collection port 6100 of the body base 6000, and the other end of which is in communication with the dust collection chamber 2100. When the self-cleaning dust collection seat is in a state of dust collection, sufficient negative pressure is formed in the dust collection bin 3000 to suck the garbage in the dust box 300 to a dust bag in the dust collection chamber 2100 via the dust collection port 6100 and the air duct.

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

Referring to FIGS. 1-2, in some embodiments, the self-cleaning dust collection seat further includes a dust bag support 2110, and the dust bag support 2110 is configured to mount the dust bag. The dust bag support 2110 is arranged in the dust collection bin 3000, for example, arranged on an inner side wall of the dust collection bin 3000 by means of a fixing component, for example, a screw, or fixed to a bottom surface of the dust collection bin 3000 by the bottom of the dust bag support 2110.

The dust bag support 2110 has a hollow cavity inside, and the hollow cavity serves as a 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 support 2110 includes a support side wall 2111 facing towards the inside of the dust collection bin 3000, and the support side wall 2111 is provided with a dust outlet port 2112. The dust outlet port 2112 is in communication with the dust collection port 6100 through the air duct, and the air duct is configured to guide the garbage into the dust collection bin 3000, for example, into the dust bag in the dust collection bin 3000. The dust outlet port 2112 is configured to be in communication with an inlet of the dust bag, to collect the garbage into the dust bag.

The dust bag support 2110 further includes a sliding baffle 2113 capable of sliding on the support side wall 2111. The sliding baffle 2113 is configured to be switchable between a first position and a second position. The sliding baffle 2113 shields the dust outlet port 2112 in response to the sliding baffle 2113 being in the first position, and the sliding baffle 2113 exposes the dust outlet port 2112 in response to the sliding baffle 2113 being in the second position. Since the dust bag is a consumable item, it can be detachably mounted with the dust bag support 2110. With this design, when the dust bag is not mounted in the dust bag support 2110, since the sliding baffle 2113 shields the dust outlet port 2112 and isolates the dust collection bin 3000 from the air duct, a suction force generated by the fan cannot enter the air duct from the dust collection bin, which prevents the garbage from entering the dust collection bin 3000 not provided with the dust bag.

FIG. 8 is a schematic structural diagram of a dust bag according to some embodiments of the present disclosure, in which a sliding plate is in a closed position. FIG. 9 is a schematic structural diagram of a dust bag according to some embodiments of the present disclosure, in which the sliding plate is in an open position. FIG. 9A is a schematic diagram of a partial structure of the dust bag according to some embodiments of the present disclosure. FIG. 9B is a schematic structural diagram of a section in FIG. 9A. FIG. 9A shows a section of the dust bag, and the dust bag is not shown in FIG. 9 or FIG. 9B.

In some embodiments, as shown in FIGS. 8-9B, the present disclosure further provides a dust bag 2120, and the dust bag 2120 is configured to be detachably mounted on the dust bag support 2110 to collect the garbage.

The dust bag 2120 includes a dust bag body 2121, a clamping plate 2122 and a sliding plate 2123. The dust bag body 2121 is made of, for example, a material that is breathable but can filter fine particles, such as a non-woven fabric or a paper material, and the dust bag body 2121 is configured to accommodate the garbage. The clamping plate 2122 is fixedly connected to the dust bag body 2121. The clamping plate 2122 is provided with a clamping plate opening 21221, and the clamping plate opening 21221 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 be switched between the closed position and the 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 the sliding plate 2123 exposes the clamping plate opening 21221 in response to the sliding plate 2123 being in the open position.

Specifically, as shown in FIGS. 8 and 9, the sliding plate 2123 is provided with 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 coincide 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, an orthographic projection of the sliding plate opening 21231 on the clamping plate 2122 at least partially coincides with the clamping plate opening 21221, and the sliding plate 2123 exposes at least a part of the clamping plate opening 21221 through the sliding plate opening 21231, as shown in FIG. 9.

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

The sliding fit between the sliding plate 2123 and the clamping plate 2122 allows the inlet of the dust bag to be closed to prevent the garbage in the dust bag from leakage.

In some embodiments, as shown in FIGS. 8-9B, an edge of the clamping plate opening 21221 is provided with a flexible rubber ring 21224 that protrudes toward the sliding plate 2123. In response to the sliding plate 2123 being in the open position, the flexible rubber ring 21224 passes through the sliding plate opening 21231 and protrudes in a direction away from the sliding plate 2123, so that when the sliding plate opening 21231 is butted with the clamping plate opening 21221, a slit at the butt joint between the two openings of the sliding plate 2123 and the clamping plate 2122 is blocked to make the sliding plate opening 21231 and the clamping plate opening 21221 be butted with each other in a sealing manner. In response to the sliding plate 2123 being not in the open position, for example, being in the closed position, at least a part of the flexible rubber ring 21224 may be squeezed between the sliding plate 2123 and the clamping plate 2122 to increase the friction therebetween, so that the sliding plate 2123 and the clamping plate 2122 can only slide relative to each other under the action of a certain external force, and the sliding plate 2123 can be stably kept in the closed position to prevent the garbage in the dust bag from being scattered.

In some embodiments, as shown in FIGS. 8 and 9, the sliding plate 2123 is capable of sliding relative to the clamping plate 2122 in a first direction M. The sliding plate 2123 includes a limiting bump 21234 arranged on at least one side of the sliding plate 2123, for example, on two sides of the sliding plate 2123. The number of limiting bumps 21234 is, for example, two, which protrude from the sliding plate 2123 in a second direction perpendicular to the first direction M.

The clamping plate 2122 includes limiting components 21223 arranged at two ends of the clamping plate 2122 in the first direction and configured to block the limiting bumps 21233 in the first direction M so as to prevent the sliding plate 2123 from disengaging from the clamping plate 2122. The number of limiting components 21223 is, for example, four, which are symmetrically distributed on two sides of the clamping plate 2122. When the sliding plate 2123 slides relative to the clamping plate 2122, the limiting bumps 21233 may only move between the corresponding limiting components 21223 located at the two ends of the clamping plate 2122 in the first direction.

In some embodiments, the sliding plate 2123 further includes a handle portion 21232 disposed at an end of the sliding plate in the first direction M and configured to facilitate the holding of an operator to move the sliding plate 2123.

The dust bag 2120 is configured to be detachably mounted on the dust bag support 2110. 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 clamping plate opening 21221 is butted with the dust outlet port 2112. Based on the above arrangement, when the dust bag support 2110 is not mounted in the dust bag 2120, the sliding baffle 2113 is in the first position and shields the dust outlet port 2112, and a suction force generated by the fan cannot enter the air duct from the dust collection bin, preventing the garbage from entering the dust collection bin 3000 not provided with the dust bag 2120.

When the dust bag 2120 is removed from the dust bag support 2110, the sliding plate 2123 is in the closed position to prevent the garbage in the dust bag from being scattered in the dust collection bin. Moreover, the sealed dust bag also prevents the garbage in the dust bag from being scattered to an external environment.

When the dust bag 2120 is not mounted in the dust bag support 2110, the sliding plate 2123 shields the clamping plate opening 21221 of the clamping plate 2122, so that when the dust bag is mounted in the dust bag support 2110, the sliding baffle 2113 may be pushed from the first position to the second position and fixed in the second position under the cooperation of the sliding plate 2123 and the clamping plate 2122. When the dust bag 2120 is withdrawn from the dust bag support 2110, the sliding plate 2123 shields the clamping plate opening 21221 to avoid leakage of the garbage. The clamping plate opening 21221 (i.e., the inlet of the dust bag) is butted with the dust outlet port 2112 after the dust bag support 2110 is provided with the dust bag 2120. Under the action of the airflow provided by the fan, the garbage in the dust box of the automatic cleaning device may be collected into the dust bag body 2121 through the dust collection port 6100 on the body base 6000, the air duct in the self-cleaning dust collection seat, the dust outlet port 2112 on the dust bag support 2110 and the clamping plate opening 21221 on the dust bag 2120 in sequence.

When the dust bag 2120 is mounted in the dust bag support 2110, the clamping plate 2122 and the sliding plate 2123 of the dust bag 2120 face towards the support side wall 2111 of the dust bag support 2110. In the process of inserting the clamping plate 2122 and the sliding plate 2123 into the sliding groove 2114 in the extension direction X′ of the sliding groove 2114, the sliding baffle 2113 may be pushed to move from the first position to the second position.

In some embodiments, a sliding baffle protrusion 21131 is arranged at a lower end of the sliding baffle 2113, and the sliding baffle protrusion 21131 is a strip-shaped protrusion along a lower edge of the sliding baffle 2113 toward the dust collection bin 3000. The lower end of the sliding plate 2123 may abut against the sliding baffle protrusion 21131 after the sliding plate 2123 is inserted into the sliding groove 2114. By the lower end of the sliding plate 2123 and the sliding baffle protrusion 21131 abutting against each other, the sliding baffle 2113 may also be pushed to slide in the extension direction X′ of the sliding groove when the sliding plate 2123 slides downward in the extension direction X′ of the sliding groove 2114. In some embodiments, a sliding plate protrusion 21233 is also arranged at a lower end of the sliding plate 2123, and the sliding plate protrusion 21233 may be a strip-shaped protrusion along a lower edge of the sliding plate 2123 toward the dust collection bin 3000.

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

As shown in FIG. 11 and FIG. 12, a latch part 21141 such as an elastic latch is arranged inside the sliding groove 2114, which may move in an approximate arc line as shown by an arrow in FIG. 12. The clamping plate 2122 is provided with a clamping plate slot 21222 that matches the latch part 21141, and the latch part 21141 is clamped into the clamping plate slot 21222 in response to the dust bag 2120 being mounted on the dust bag support 2110. The clamping plate 2122 slides to a clamping position in the extension direction X′ of the sliding groove 2114, the clamping plate opening 21221 is butted with the dust outlet port 2112, and the latch part 21141 is cooperatively clamped with the clamping plate slot 21222, so that the dust bag 2120 is fixed to the dust bag support 2110.

A limiting bump 21234 on the sliding plate 2123 also serves as an unlocking bump 21234, and is also referred to as the unlocking bump 21234, and is configured to squeeze, during withdrawal of the sliding plate 2123 from the sliding groove 2114, the latch part 21141 to cause the latch part 21141 to disengage from the clamping plate slot 21222, so as to release the clamping plate 2122 from the latch part 21141 and make the dust bag 2120 successfully disengage from the dust bag support 2110. In some embodiments, the unlocking bump 21234 also has a limiting function and cooperates with the limiting component 21223 on the clamping plate 2122 to prevent the sliding plate 2123 from disengaging from the clamping plate 2122.

In some embodiments, as shown in FIG. 13, the dust bag support 2110 is provided with an elastic component 2115 such as a spring. The elastic component 2115 is connected to the sliding baffle 2113, and is configured to make the sliding baffle 2113 have 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, so that the sliding baffle 2113 shields the dust outlet port 2112. In some embodiments, the elastic component 2115 is located inside the dust bag support 2110, and an extension direction of the elastic component 2115 is substantively the same as that of the sliding groove 2114. The elastic component 2115 has one end fixed to an upper portion of the dust bag support 2110, and the other end connected to the sliding baffle 2113. The number of elastic components 2115 may be one or more. When the number of elastic components 2115 is, for example, two, the two elastic components may be respectively arranged at two opposite ends of the dust bag support 2110.

The process of mounting and dismounting the dust bag 2120 and the dust bag support 2110 will be described in detail below.

When the dust bag support 2110 is not provided with the dust bag 2120, the sliding baffle 2113 on the dust bag support 2110 is in the first position and shields the dust outlet port 2112, and the sliding plate 2123 on the dust bag 2120 is in the closed position and shields the clamping plate opening 2122, which are just the state as shown in FIG. 8. In the process of mounting the dust bag 2120 in the dust bag support 2110, the clamping plate 2122 and the sliding plate 2123 are inserted into the sliding groove 2114 in the extension direction X′ of the sliding groove 2114, and 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 clamping plate 2122, such that the sliding plate opening 21231 on the sliding plate 2123 is aligned with the clamping plate opening 21221 on the clamping plate 2122. Meanwhile, the clamping plate 2122 and the sliding plate 2123 push the sliding baffle 2113 to move from the first position to the second position, so that the sliding baffle 2113 exposes the dust outlet port 2112. When the clamping plate 2122 slides to a clamping position in the extension direction X′ of the sliding groove 2114, the clamping plate opening 21221 is butted with the dust outlet port 2112, and the latch part 21141 is cooperatively clamped with the clamping plate slot 21222, so that the dust bag 2120 is fixed to the dust bag support 2110. In this case, the flexible rubber ring 21224 on the dust bag passes through the sliding plate opening 21231 and abuts against an edge of the dust outlet port 2112, so that the clamping plate opening 21221 of the dust bag is butted with the dust outlet port 2112 of the dust bag support in a sealing manner, so as to avoid leakage of the garbage during dust collection.

When the dust bag 2120 is removed from the dust bag support 2110, the operator holds the handle portion 21232 of the sliding plate 2123 to gradually withdraw the sliding plate 2123 from the sliding groove 2114 of the dust bag support 2110. In this process, the sliding plate 2123 gradually moves from the open position to the closed position relative to the clamping plate 2122, so that the sliding plate 2123 shields the clamping plate opening 21221. Moreover, the unlocking bump 21234 on the sliding plate 2123 squeezes the latch part 21141, so that the latch part 21141 disengages from the clamping plate slot 21222. Meanwhile, due to the interaction between the unlocking bump 21234 and the limiting component 21223 on the clamping plate 2122, the handle portion 21232 of the sliding plate 2123 can be continuously pulled to withdraw the sliding plate 2123 and the clamping plate 2122 from the sliding groove 2114 of the dust bag support 2110. The dust bag 2120 disengages from the dust bag support 2110, and the sliding baffle 2113 returns to the first position under the action of the elastic component, so that the sliding baffle 2113 shields the dust outlet port 2112.
