[0013] Optional embodiments of the present disclosure will be described in detail below
with reference to the accompanying drawings.
[0014] In the related art, due to a limited capacity of a dust box of an automatic cleaning
device, a user often needs to bend down to clean the dust box, resulting in poor user
experience. Therefore, an embodiment of the present disclosure provides a self-cleaning
dust collection base, which collects garbage in the dust box of an automatic cleaning
device into a dust collection bin of the self-cleaning dust collection base in a centralized
manner by means of a dust collection system, thereby reducing the frequency of garbage
disposal by a user and improving the user experience. Specifically, as an example
of the self-cleaning dust collection base according to an embodiment of the present
disclosure, FIG. 1 schematically shows a schematic diagram of an overall structure
of the self-cleaning dust collection base, and FIG. 2 schematically shows a schematic
structural diagram of a self-cleaning dust collection base body from which a sewage
tank, a clean water tank and a dust collection hood are removed in the present disclosure.
[0015] In order to describe a behavior of the self-cleaning dust collection base more clearly,
the following directions are defined. The self-cleaning dust collection base may be
defined by the following three axes as defined, which are perpendicular to each other:
a transverse axis Y, a front-rear axis X and a central vertical axis Z. A direction
opposite to an arrow along the front-rear axis X, i.e., a direction in which the automatic
cleaning device enters the self-cleaning dust collection base is marked as a "rearward
direction", and a direction of an arrow along the front-rear axis X, i.e., a direction
in which the automatic cleaning device leaves the self-cleaning dust collection base
is marked as a "forward direction". The transverse axis Y is substantially in a width
direction of the self-cleaning dust collection base body. The vertical axis Z is a
direction along upward extension from a bottom surface of the self-cleaning dust collection
base.
[0016] As shown in FIG. 1, a direction in which a self-cleaning dust collection base bottom
plate 1000 protrudes from a self-cleaning dust collection base body 2000 is a forward

[0038] The present disclosure further provides a dust collection system, including an automatic
cleaning device and the self-cleaning dust collection base described in the foregoing
embodiments.
[0039] Owing to the design that the dust collection hood is placed on the dust collection
chamber with the opening facing downwards, the dust collection hood and the dust collection
chamber are combined more closely under the action of a fan, which further improves
the dust collection efficiency. And, the exposed design of the dust collection hood
makes it convenient for a user to visualize the situation inside the dust collection
hood and deal with the dust collection chamber in a more timely manner, e.g., to replace
the dust bag.
[0040] In the related art, due to a limited capacity of a dust box of an automatic cleaning
device, a user often needs to bend down to clean the dust box, resulting in poor user
experience. Therefore, an embodiment of the present disclosure provides a self-cleaning
dust collection base. The garbage in the dust box of the automatic cleaning device
is collected into the dust collection bin of the self-cleaning dust collection base
by means of a dust collection system. By providing the dust bag support and the dust
bag in the dust collection bin, the garbage in the dust box is basically transferred
to the dust bag located in the dust collection bin without leakage, thus reducing
the frequency of garbage disposal by the user and improving the user experience. In
addition, the dust bag adopts a design that a fastening plate corporates with a sliding
plate. When the dust bag is removed from the dust bag support, the sliding plate is
in a closed position, preventing the garbage in the dust bag from being scattered
in the dust collection bin.
[0041] Specifically, as an example of the self-cleaning dust collection base according to
the embodiment of the present disclosure, FIG. 1 is a schematic diagram of an overall
structure of the self-cleaning dust collection base, and FIG. 2 is a schematic structural
diagram of a self-cleaning dust collection base body from which a sewage tank, a clean
water tank and a dust collection hood are removed.
[0042] As shown in FIG. 1, a direction in which a self-cleaning dust collection base bottom
plate 1000 protrudes from a self-cleaning dust collection base body 2000 is a forward
direction, and a direction of a rear wall of the self-cleaning dust collection base
body 2000 is a rearward direction. A dust collection bin 3000 is located on a left
side of the self-cleaning dust collection base, a clean water tank 4000 is located
on a right side of the dust collection bin 3000, and a sewage tank 5000 is located
on a right side of the clean water tank 4000.
[0043] The self-cleaning dust collection base body 2000 is configured to collect garbage
in the dust bag of the automatic cleaning device. In some embodiments, components
such as the dust collection bin 3000, the clean water tank 4000, and the sewage tank
5000 may also be arranged side by side on the self-cleaning dust collection base body
2000. Specifically, as shown in FIG. 2, the self-cleaning dust collection base body
2000 includes a water storage chamber 2700 and a dust collection chamber 2100. The
water storage chamber 2700, with an opening facing upward and forward, is arranged
at a top of the self-cleaning dust collection base body 2000. The water storage chamber
may further include a clean water bin for accommodating the clean water tank 4000
and a sewage bin for accommodating the sewage tank 5000. The dust collection chamber
2100 (with an opening facing upward and forward) and the water storage chamber 2700
are arranged at the top end of the self-cleaning dust collection base body 2000 side
by side. A dust collection hood 2800 that matches the opening of the dust collection
chamber 2100 is arranged on the dust collection chamber 2100, and the dust collection
hood 2800 is detachably placed on the dust collection chamber 2100. The dust collection
chamber 2100 and the dust collection chamber 2800 jointly form the dust collection

[0047] In some embodiments, the self-cleaning dust collection base 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 base 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 into the dust bag in the dust collection
chamber 2100 through the dust collection port 6100 and the air duct.
[0048] 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 another schematic structural diagram of the dust bag support according
to some embodiments of the present disclosure, in which the sliding baffle is in a
second position.
[0049] Referring to FIGs. 1 to 2, in some embodiments, the self-cleaning dust collection
base further includes a dust bag support 2110, and the dust bag support 2110 is configured
to install 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.
[0050] The dust bag support 2110 is internally provided with a hollow cavity, and the hollow
cavity is used as a part of the air duct of the self-cleaning dust collection base,
for example, as a tail end of the air duct.
[0051] The dust bag support 2110 includes a support side wall 2111 facing 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 communicated with the dust collection
port 6100 by means of 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 communicated with an inlet
of the dust bag, for collecting the garbage into the dust bag.
[0052] 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

and the sliding baffle 2113 exposes the dust outlet port 2112 in response to the sliding
baffle 2113 being in the second position. The dust bag is a consumable item detachably
installed in the dust bag support 2110. With this design, when the dust bag is not
installed in the dust bag support 2110, the sliding baffle 2113 may shield the dust
outlet port 2112, and isolate the dust collection bin 3000 from the air duct, so that
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 where the
dust bag is not installed.
[0053] 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 another schematic structural diagram of the 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 cross-section in FIG. 9A. FIG. 9A shows a cross-section of the dust bag, while the
dust bag is not shown in FIG. 9 or FIG. 9B.
[0054] In some embodiments, as shown in FIGs. 8 to 9B, the present disclosure further provides
a dust bag 2120. The dust bag 2120 is configured to be detachably installed on the
dust bag support 2110 for collecting the garbage.
[0055] The dust bag 2120 includes a dust bag body 2121, a fastening 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 fastening plate
2122 is fixedly connected to the dust bag body 2121. The fastening plate 2122 is provided
with a fastening plate opening 21221, and the fastening plate opening 21221 serves
as an inlet of the dust bag body 2121. The sliding plate 2123 is slidably connected
to the fastening plate 2122 and configured to be switched between the closed position
and the open position. The sliding plate 2123 shields the fastening plate opening
21221 in response to the sliding plate 2123 being in the closed position, and the
sliding plate 2123 exposes the fastening plate opening 21221 in response to the sliding
plate 2123 being in the open position.
[0056] Specifically, as shown in FIGs. 8 and 6, 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 fastening plate 2122 does not overlap with the fastening plate opening 2821, and
the sliding plate 2123 shields the fastening plate opening 22121, as shown in FIG.
8. In response to the sliding plate 2123 being in an open position, an orthographic
projection of the sliding plate opening 21231 on the fastening plate 2122 at least
partially overlaps with the fastening plate opening 21221, and the sliding plate 2123
exposes at least a part of the fastening plate opening 21221 through the sliding plate
opening 21231, as shown in FIG. 9.
[0057] In some embodiments, a size of the sliding plate opening 21231 is, for example, larger
than that of the fastening plate opening 21221, and the orthographic projection of
the sliding plate opening 21231 on the fastening plate 2122 covers the fastening plate
opening 21221 in response to the sliding plate 2123 being in the closed position.
In some embodiments, the size of the sliding plate opening 21231 is, for example,
smaller than that of the fastening plate opening 21221, and the orthographic projection
of the sliding plate opening 21231 on the fastening plate 2122 falls within the fastening
plate opening 21221 in response to the sliding plate 2123 being in the closed position.
In some embodiments, the size of the sliding plate opening 21231 is, for example,
equal to that of the fastening plate opening 21221, and the orthogonal projection
of the sliding plate opening 21231 on the fastening plate 2122 substantially coincides
with the fastening plate opening 21221 in response to the sliding plate 2123 being
in the closed position.
[0058] The sliding fit between the sliding plate 2123 and the fastening plate 2122 allows
the inlet of the dust bag to be closed to prevent the garbage in the dust bag from
leakage.
[0059] In some embodiments, as shown in FIGs. 8 to 9B, an edge of the fastening 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 interfaces with the fastening plate opening 21221, a slit at the position where
the two openings of the sliding plate 2123 and the fastening plate 2122 interface
with each other is blocked to make the sliding plate opening 21231 and the fastening
plate opening 21221 interface 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 fastening plate 2122 to increase the friction therebetween,
so that the sliding plate 2123 and the fastening 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.
[0060] In some embodiments, as shown in FIGs. 8 and 9, the sliding plate 2123 may slide
relative to the fastening plate 2122 in a first direction M. The sliding plate 2123
includes a limiting bump 21243 arranged on at least one side of the sliding plate
2123, for example, on two sides of the sliding plate 2123. The number of the limiting
bumps 21243 is, for example two, and the limiting bumps 21243 protrude from the sliding
plate 2123 in a second direction perpendicular to the first direction M. The fastening
plate 2122 includes limiting components 21223 arranged at two ends of the fastening
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 fastening plate 2122. The number of the limiting components 21223 is, for
example four, and the limiting components 21223 are symmetrically distributed on two
sides of the fastening plate 2122. When the sliding plate 2123 slides relative to
the fastening plate 2122, the limiting bumps 21233 may only move between the corresponding
limiting components 21223 located at two ends of the fastening plate 2122 in the first
direction.
[0061] 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
be conveniently held by an operator to move the sliding plate 2123.
[0062] The dust bag 2120 is configured to be detachably installed on the dust bag support
2110. In response to the dust bag 2120 being installed 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 fastening plate opening 21221 interfaces
with the dust outlet port 2112. Based on the above arrangement, when the dust bag
support 2110 is not installed in the dust bag 2120, the sliding baffle 2113 is in
the first position, the dust outlet port 2112 is shielded, and a suction force generated
by the fan cannot enter the air duct from the dust collection bin, thus preventing
the garbage from entering the dust collection bin 3000 where the dust bag 2120 is
not installed.
[0063] 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.
[0064] When the dust bag 2120 is not installed in the dust bag support 2110, the sliding
plate 2123 shields the fastening plate opening 21221 of the fastening plate 2122,
so that when the dust bag is installed 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 fastening
plate 2122. When the dust bag 2120 is withdrawn from the dust bag support 2110, the
sliding plate 2123 shields the fastening plate opening 21221 to avoid leakage of the
garbage. The fastening plate opening 21221 (i.e., the inlet of the dust bag) interface
with the dust outlet port 2112 after the dust bag 2120 is installed in the dust bag
support 2110. 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 base, the dust outlet port 2112 on the dust bag
support 2110 and the fastening plate opening 21221 on the dust bag 2120 in sequence.
[0065] FIG. 10 is a schematic diagram of a pre-assembled structure of the dust bag support
and the dust bag according to some embodiments of the present disclosure, and FIG.
11 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.
[0066] In some embodiments, as shown in FIGs. 6 to 11, the dust bag support 2110 includes
a socket 2114, and at least a part of the sliding baffle 2113 is located in the socket
2114, so that the sliding baffle 2113 may slide in an extension direction X' of the
socket 2114, and thus be switched between the first position and the second position.
The number of the sockets 2114 is, for example, one or more. As shown in FIGs. 6 to
11, the number of the sockets 2114 is, for example, two, and the sockets 2114 are
respectively arranged at two opposite ends of the support side wall 2111 of the dust
bag support 2110. The two sockets 2114 respectively accommodate the two opposite ends
of the sliding baffle 2113, so that the sliding baffle 2113 may slide in the extension
direction X' of the socket 2114.
[0067] As shown in FIGs. 6 to 11, the fastening plate 2122 and the sliding plate 2123 of
the dust bag 2120 are configured to be insertable into the socket 2114 to slide along
the socket 2114 in the extension direction X', and the sliding baffle 2113 is pushed
to slide in the extension direction X' of the socket such that the dust bag 2120 is
installed in the dust bag support 2110. Specifically, two ends of the fastening plate
2122 and the sliding plate 2123 of the dust bag 2120 may be respectively inserted
into the two sockets 2114 described above. In response to the dust bag 2120 being
installed on the dust bag support 2110, the sliding plate 2123 is in the open position
to expose the fastening plate opening 21221, and the sliding baffle 2113 is in the
second position to expose the dust outlet port 2112, so that the fastening plate opening
21221 interfaces with the dust outlet port 2112.
[0068] As shown in FIG. 10, in the process of installing the dust bag 2120 in the dust bag
support 2110, the dust bag 2120 moves relative to the dust bag support 2110 in the
extension direction X' of the socket 2114. During the installment, the fastening plate
2122 and the sliding plate 2123 of the dust bag 2120 face the support side wall 2111
of the dust bag support 2110. In the process of inserting the fastening plate 2122
and the sliding plate 2123 into the socket 2114 in the extension direction X' of the
socket 2114, the sliding baffle 2113 may be pushed to move from the first position
to the second position.
[0069] 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 socket 2114. Since
the lower end of the sliding plate 2123 abuts against the sliding baffle protrusion
21131, the sliding baffle 2113 may also be pushed to slide in the extension direction
X' of the socket when the sliding plate 2123 slides downward in the extension direction
X' of the socket 2114. In some embodiments, a sliding plate protrusion 21233 is also
arranged at the lower end of the sliding plate 2123, and the sliding plate protrusion
21233 may be a strip-shaped protrusion along the lower edge of the sliding plate 2123
toward the dust collection bin 3000. The sliding plate protrusion 21233 may exactly
abut against the upper side of the sliding baffle protrusion 21131 after the sliding
plate 2123 is inserted into the socket 2114. Since the sliding plate protrusion 21233
abuts against the sliding baffle protrusion 21131, the sliding baffle 2113 may also
be pushed to slide in the extension direction X' of the socket when the sliding plate
2123 slides downward in the extension direction X' of the socket 2114.
[0070] 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.
[0071] As shown in FIG. 11 and FIG. 12, the socket 2114 is internally provided with a fastening
portion 21141, for example, an elastic snap joint, which can move in an approximate
arc line as shown by an arrow in FIG. 12. The fastening plate 2122 is provided with
a fastening plate slot 21222 that matches the fastening portion 21141, and the fastening
portion 21141 is snapped in the fastening plate slot 21222 in response to the dust
bag 2120 being installed on the dust bag support 2110. The fastening plate 2122 slides
to a snap-in position in the extension direction X' of the socket 2114, the fastening
plate opening 21221 interfaces with the dust outlet port 2112, and the fastening portion
21141 is cooperatively snapped with the fastening plate slot 21222, so that the dust
bag 2120 is fixed to the dust bag support 2110.
[0072] A limiting bump 212234 on the sliding plate 2123 also serves as an unlocking bump
21234 (also referred to as the unlocking bump 21234), and is configured to squeeze,
during withdrawal of the sliding plate 2123 from the socket 2114, the fastening portion
21141 to cause the fastening portion 21141 to disengage from the fastening plate slot
21222, so as to release the fastening plate 2122 from the fastening portion 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 fastening plate 2122 to prevent the sliding
plate 2123 from disengaging from the fastening plate 2122.
[0073] In some embodiments, as shown in FIG. 13, the dust bag support 2110 is provided with
an elastic component 2115, for example, a spring. The elastic component 2115 is connected
to the sliding baffle 2113, and is configured to make the sliding baffle 2113 to have
a trend to be in the first position. The sliding baffle 2113 is in the first position
under the action of the elastic component 2115 when the sliding baffle 2113 is not
subjected to an external force, 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 basically
the same as that of the socket 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 the elastic components 2115 may be one or more.
When the number of the elastic components 2115 is two, for example, the two elastic
components may be respectively arranged at two opposite ends of the dust bag support
2110.
[0074] The process of installment and removal of the dust bag 2120 and the dust bag support
2110 will be described in detail below.
[0075] When the dust bag support 2110 is not installed in the dust bag 2120, the sliding
baffle 2113 on the dust bag support 2110 is in the first position, the dust outlet
port 2112 is shielded, the sliding plate 2123 on the dust bag 2120 is in the closed
position, and the fastening plate opening 2122 is shielded, just as shown in FIG.
8. In the process of installing the dust bag 2120 in the dust bag support 2110, the
fastening plate 2122 and the sliding plate 2123 are inserted into the socket 2114
in the extension direction X' of the socket 2114, and the sliding plate 2123 gradually
moves from the closed position to the open position relative to the fastening plate
2122 when a user holds the handle portion 21232 of the sliding plate 2123 to push
the dust bag 2120 into the socket 2114, such that the sliding plate opening 21231
on the sliding plate 2123 is aligned with the fastening plate opening 21221 on the
fastening plate 2122. Meanwhile, the fastening 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 fastening
plate 2122 slides to a snap-in position in the extension direction X' of the socket
2114, the fastening plate opening 21221 interfaces with the dust outlet port 2112,
and the fastening portion 21141 is cooperatively snapped with the fastening plate
slot 21222, so that the dust bag 2120 is fixed to the dust bag support 2110. At this
time, 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
fastening plate opening 21221 of the dust bag interfaces 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.
[0076] When the dust bag 2120 is withdrawn 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 socket 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 fastening plate 2122, so that the sliding plate 2123 shields the fastening
plate opening 21221. Moreover, the unlocking bump 21234 on the sliding plate 2123
squeezes the fastening portion 21141, so that the fastening portion 21141 disengages
from the fastening plate slot 21222. Meanwhile, due to the interaction between the
unlocking bump 21234 and the limiting component 21223 on the fastening plate 2122,
the handle portion 21232 of the sliding plate 2123 can be continuously pulled to withdraw
the sliding plate 2123 and the fastening plate 2122 from the socket 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.
[0077] In some embodiments, the support side wall of the dust bag support facing the inside
of the dust collection bin is provided with the dust outlet port configured to interface
with the inlet of the dust bag. The dust bag support further includes the sliding
baffle capable of sliding on the support side wall. The sliding baffle is configured
to be switched between a first position and a second position. The sliding baffle
shields the dust outlet port in response to the sliding baffle being in the first
position, and the sliding baffle exposes the dust outlet port in response to the sliding
baffle being in the second position.
[0078] In some embodiments, the self-cleaning dust collection base further includes a dust
bag detachably installed on the dust bag support. The dust bag includes:
a dust bag body; and
a fastening plate fixedly connected to the dust bag body, wherein the fastening plate
is provided with a fastening plate opening which serves as an inlet of the dust bag.
[0079] The sliding baffle is in the first position to shield the dust outlet port in response
to the dust bag not being installed on the dust bag support, and the sliding baffle
is in the second position to expose the dust outlet port in response to the dust bag
being installed on the dust bag support, so that the fastening plate opening interfaces
with the dust outlet port.
[0080] In some embodiments, the dust bag further includes a sliding plate connected to the
fastening plate in a slidable manner and configured to be switched between a third
position and a fourth position, the sliding plate shields the fastening plate opening
in response to the sliding plate being in the third position, and the sliding plate
exposes the fastening plate opening in response to the sliding plate being in the
fourth position.
[0081] In some embodiments, the sliding plate is provided with a sliding plate opening;
in response to the sliding plate being in the third position, the sliding plate opening
does not overlap with the fastening plate opening such that the sliding plate shields
the fastening plate opening; and in response to the sliding plate being in the fourth
position, the sliding plate opening substantially overlaps with the fastening plate
opening such that the sliding plate exposes the fastening plate opening.
[0082] In some embodiments, the dust bag support includes a socket, and at least a part
of the sliding baffle is located in the socket, so that the sliding baffle slides
