position higher than the cleaning container 3. Specifically, air
pump can be used for pressurization.
[0037] As shown in FIG. 3, FIG. 3 is a schematic view of the
base.
[0038] The dirt receiving component 4 and the base 2 are detachably
connected to each other.
[0039] The dirt receiving component 4 is detachably positioned on
the bottom wall of the maintenance station, specifically, on the
bottom wall of the cavity 22. The dirt receiving component 4
includes a first connection part, the base 2 includes a second
connection part, the first connection part is engaged with the
second connection part, such that the dirt receiving component 4
and the base 2 are detachably connected to each other. The first
connection part can be a bulge, and the second connection part can
be a groove, or vice versa, thereby achieving the cooperation. For
example, the dirt receiving component 4 includes a bulge and the
bottom wall defines a groove, such that the bulge can be detachably
received in the groove. Optionally, the first connection part and
the second connection part can be detachably connected to each
other through the engagement of a sliding slot with a sliding rail.
The sliding slot or the sliding rail can be positioned on the
bottom wall or the sidewall of the cavity 22. The dirt receiving
component 4 includes a sliding rail or a sliding slot engaging with
the sliding slot or the sliding rail on the bottom wall or the
sidewall of the cavity 22 to form a sliding pair. To facilitate the
cleaning robot to climb into the cleaning container 3, the drop
height between the front baffle plate 43 and the upper surface of
the cleaning plate 32 is small. In some embodiments, the front
baffle plate 43 is roughly flush with the upper surface of the
cleaning plate 32.
[0040] In certain embodiments, the dirt receiving component 4 and
the base 2 can form a sliding pair. The sliding pair can be of a
sliding guide or a rolling guide, which is convenient for a user to
pull out the dirt receiving component 4.
[0041] The base 2 includes slotted guides 21, and the slotted
guides 21 are positioned at two opposite sides of the cavity 22.
The slotted guides 21 can be L-shaped, T-shaped, or the like. In
this embodiment, the slotted guides 21 are L-shaped, so as to match
the guide rail 42 protruding upwards from the dirt receiving
component 4. The slotted guides 21 on the base 2 and the guide
rails 42 on the dirt receiving component 4 form sliding pairs in a
sliding mode. Each of the slotted guides 21 includes a front end
face and a rear end face, and the guide rail 42 can be extend
through the front end face and the rear end face, so as to be
detached from the slotted guide 21. Specifically, two ends of the
slotted guide 21 are open for the insertion of the guide rail 42.
The front end face is capable of facing the front baffle plate 43
of the dirt receiving component 4, and the rear end face is capable
of facing the rear baffle plate 44 of the dirt receiving component
4. The front baffle plate 43, the rear baffle plate 44, and the
guide rail 42 on the sidewall of the dirt receiving component 4 can
cooperatively block the sewage from flowing out from the edge of
the dirt receiving component 4. FIGS. 1-3 show the detailed
structure of the dirt receiving component 4. To facilitate the
cleaning robot to climb into the cleaning container 3, the drop
height between the front baffle plate 43 and the upper surface of
the cleaning plate 32 is small, in some embodiments, the front
baffle plate 43 is roughly flush with the upper surface of the
cleaning plate 32.
[0042] As shown in FIG. 1, FIG. 2, and FIG. 3.
[0043] The dirt receiving component 4 is plate-shaped, and a center
part of the dirt receiving component 4 is concave to form the
sewage collection chamber 41. Compared with a barrel-shaped dirt
receiving component, the plate-shaped dirt receiving component 4 is
lighter, occupies less space, and is easy to dismount. In some
embodiments, the dirt receiving component 4 and the base 2 can form
a sliding pair, and the dirt receiving component 4 includes a base
plate, a guide rail 42, a front baffle plate 43, and a rear baffle
plate 44.
[0044] The guide rail 42 is matching the slotted guide 21, the
guide rail 42 protrudes upwards from the base plate and is
configured to block the sewage from flowing out from a side edge of
the base plate.
[0045] The front baffle plate 43 protrudes upwards from the base
plate and is configured to block the sewage from flowing out from a
front edge of the base plate.
[0046] The rear baffle plate 44 is positioned on the cleaning
container 3 and abuts against the rear end face of the slotted
guide 21.
[0047] when the dirt receiving component 4 slides into a use state
where the base plate abuts against the rear baffle plate 44, the
front baffle plate 43 abuts against the front end face, thereby
forming the dirt receiving component 4 capable of blocking the
sewage from flowing out from all the side edges of the base
plate.
[0048] Both the guide rail 42 and the front baffle plate 43
protrude upwards from the base plate, thus preventing the sewage in
the cleaning container 3 from splashing out of the dirt receiving
component 4 or flowing to the bottom of the base 2 via the guide
rail 42 when the sewage falls from the cleaning container 3 to the
dirt receiving component 4, preventing the dirt from accumulating
in the slotted guide 21, reducing the maintenance workload; in
addition, the front baffle plate 43 can operate as a handle, which
facilitates the detachment of the dirt receiving component 4. In
other embodiments, the handles in other structures can be arranged
to facilitate the detachment of the dirt receiving component 4.
Owing to the existence of the rear baffle plate 44, when the dirt
receiving component 4 slides into the use state where the base
plate abuts against the rear baffle plate 44, the front baffle
plate 43 abuts against the front end face, thereby forming the dirt
receiving component 4 capable of blocking the sewage from flowing
out from all the side edges of the base plate. Specifically, the
front baffle plate 43, the rear baffle plate 44, the slotted guide
21 positioned on the sidewall of the base, the base plate, the
guide rail 42 positioned on the base plate, the sidewalls where the
guide rails 42 are positioned, and the cleaning plate 32
cooperatively define the sewage collection chamber 41 with a top
opening. Because all the four sides of the base plate can block the
sewage, the falling sewage all accumulates in the sewage collection
chamber 41 without splashing outside. The sewage is discharged
finally via the sewage discharger 5, no need to worry about the
sewage flowing into the bottom of the base 2 or splashing on the
floor, this improves the user experience.
[0049] In alterative embodiments, a waterproof seal is positioned
between the front baffle plate 43 and the front end face of the
slotted guide 21, between the rear baffle plate 44 and the rear end
face of the slotted guide 21, and between the guide rail 42 and the
slotted guide 21, thus preventing the sewage from leaking out of
the sewage collection chamber 41. The waterproof seal can be a
rubber gasket or the like.
[0050] In another embodiment, the dirt receiving component 4 can be
detachably positioned on the lower part of the cleaning container 3
through a snap-fit connection, threaded connection, or the
like.
[0051] As shown in FIGS. 4-5, FIG. 4 is a three-dimensional view of
the dirt receiving component in a use state, and FIG. 5 is a
three-dimensional view of the dirt receiving component in other
states.
[0052] The arrangement of the sliding pair enables the sewage
collection chamber 41 to be opened or closed like a drawer. The
dirt receiving component 4 has the following two states:
[0053] when the dirt receiving component 4 slides from an original
position as shown in FIG. 5 until the base plate abuts against the
rear baffle plate 44, as shown in FIG. 4, the front baffle plate 43
abuts against the front end face, thereby forming the dirt
receiving component 4 capable of blocking the sewage from flowing
out from all the side edges of the base plate, in this state, the
sewage collection chamber 41 is a sealed chamber with a top
opening;
[0054] when the dirt receiving component 4 slides from an original
position as shown in FIG. 4 until the base plate is separated from
the rear baffle plate 44, as shown in FIG. 5, the dirt receiving
component 4 continues sliding and completely separates from the
base 2, at this time, the detached dirt receiving component 4 can
be cleaned independently, and there is no need for the users to
squat down or lift the whole maintenance station to clean the
bottom of the cavity 22, which is very convenient. Moreover, the
plate-shaped dirt receiving component 4 is lighter and easy to pull
out compared with a barrel-shaped one.
[0055] In this embodiment, the dirt receiving component 4 operates
as a transfer station of the sewage, and can be connected to the
sewage discharger 5 to discharge the sewage. In another embodiment,
the dirt receiving component 4 defines a bottom opening
communicating with a sewer, or is positioned next to a sewer, or
one end of the drainage pipe 52 communicates with the bottom
opening, the other end of the drainage pipe 52 is connected to the
swage tank.
[0056] As shown in FIG. 6, FIG. 6 is a schematic view of the sewage
collection chamber according to another embodiment.
[0057] The sewage collection chamber 41 can be formed in the
following connection relationship: the cleaning plate 32 can be
directly superposed on the dirt deposition plate. The sewage
collection chamber 41 is a chamber concave in the dirt deposition
plat. In this way, the front baffle plate 43, the rear baffle plate
44, and the guide rail 42 protruding upwards from the base plate
can be omitted, the sewage directly falls into the sewage
collection chamber 41 via the drain holes 321 by gravity.
[0058] As shown in FIGS. 7-8, FIG. 7 is a schematic view of the
dirt receiving component according to another embodiment, and FIG.
8 is a local enlarged view of part B in FIG. 7.
[0059] The center of the dirt receiving component 4 can be concave
in various forms. As shown in FIG. 1, the central part of the dirt
receiving component 4 includes an ellipsoid or spherical groove; as
shown in FIG. 7, the dirt receiving component 4 includes a bottom
plate and a plurality of side plates connected to the bottom plate,
and the bottom plate and the plurality of side plates cooperatively
form a cavity structure. In this way, the dirt receiving component
4 has a larger storage space. The cross-section of the cavity
structure can be rectangular, or the cavity structure is
cone-shaped and other shapes, all of which defines a concave in the
center thereof.
[0060] The front baffle plate 43 protrudes upwards, thus
facilitating to draw out the dirt receiving component 4 for
cleaning; the guide rail 42 also protrudes upwards, thus
effectively preventing the sewage from entering the slotted guide
21 from a side of the slotted guide 21, further preventing the
contamination from be generated in the slotted guide 21. When the
guide rail 42 is not raised upwards and bent, the sewage can enter
into the slotted guide 21 to produce dirt, and the narrow space in
the slotted guide 21 is difficult to clean up, so it is easy to
cause odor in the slotted guide 21. The guide rail 42 protruding
upwards can effectively prevent the dirt and odor from be generated
in the slotted guide 21.
[0061] As shown in FIG. 9, FIG. 9 is a local enlarged view of part
A in FIG. 1.
[0062] The cleaning plate 32 can be flat in shape or a center of
the cleaning plate 32 is concave. Optionally, the concave center of
the cleaning plate 32 is the same as that of the dirt receiving
component 4, or other concave structures such that the sewage can
flow from the edge into the concave center, for example, the entire
cleaning plate 32 is a curved panel with higher edge and lower
middle part. In this embodiment, the cleaning plate 32 defines a
plurality of drain holes 321 which form the sewage outlet. The
plurality of drain holes 321 communicates with the sewage
collection chamber 41. When the center of the dirt receiving
component 4 is concave to form an ellipsoidal or spherical cavity,
the plurality of drain holes 321 is preferably arranged above the
ellipsoidal or spherical cavity vertically. The plurality of drain
holes 321 can also be positioned at any position on the cleaning
plate 32, as shown in FIG. 12. The connection mode of the cleaning
plate 32 and the base 2 can be a fixed connection or movable
connection. For example, the cleaning plate 32 can be detachably
connected to the base through the engagement of a slide rail with d
a slide slot.
[0063] The maintenance station further includes a clean water
nozzle 62 positioned in the cleaning container 3 and facing the
scrubbing component 11, the clean water nozzle 62 communicates with
the water inlet pipe 61. The clean water nozzle 62 is positioned in
the cleaning container 3, when in use, the clean water nozzle 62
faces the scrubbing component 11, the clean water from the water
inlet pipe 61 is sprayed on the scrubbing component 11. The sewage
generated during the cleaning flows naturally to the sewage
collection chamber 41 through the drain holes 321 by gravity. FIG.
11 shows the detailed arrangement of the clean water nozzle 62.
[0064] The scrubbing component 11 of the cleaning robot 1 is in
contact with the protrusion part 31 of the cleaning container 3.
The rotating scrubbing component 11 is cleaned by the protrusion
part 31. The protrusion part 31 can be a protrusion part including
a ribbed plate structure, and the ribbed plate structure can be in
various forms. In this embodiment, the protrusion part 31 is an
integrated protrusion part 31 including a plurality of ribbed
plates as shown in FIG. 9, and the plurality of ribbed plates is
positioned at equal angles with the vertical straight line as the
axis. In another embodiment, as shown in FIG. 10, the protrusion
part 31 is a split-type structure including a plurality of ribbed
plates. As a variant, the protrusion part 31 can be a protrusion
part including a structure different from the ribbed plate
structure, for example, can be a spherical or ellipsoidal
protrusion part 31 protruding upwards as a whole.
[0065] The maintenance station further includes a drainage pipe 52.
The drainage pipe 52 includes a detachable part 521 and a fixed
part 522. The detachable part 521 communicates with the sewage
collection chamber 41. An end of the fixed part 522 is detachably
connected to the detachable part 521, and another end of the fixed
part 522 is connected to the sewage tank 51. The detachable part
521 is detachably connected to the fixed part 522, when the
drainage pipe 52 is blocked, the detachable part 521 is detached
from the fixed part 522. Compared with a conventional structure
that the drainage pipe 52 is directly connected to the sewage
collection chamber 41 and the sewage discharge end, the detachable
drainage pipe 52 of this embodiment of the present disclosure can
easily clean and discharge the sediment. Specifically, the
detachable part 521 is connected to the sewage collection chamber
41, the detachable part 521 runs through the bottom or the side of
the sewage collection chamber. The detachable part 521 can be
detachably connected to the sewage collection chamber 41 through a
screw connection, a snap-fit connection or the like. The detachable
part 521 can also directly extend into the sewage collection
chamber 41 from the upper part of the dirt receiving component 4.
In this way, the fixed mode of the detachable part 521 and the
sewage collection chamber 41 can be snap-fit connection,
muff-coupling or the like. For example, the detachable part 521
includes a hook, and the dirt receiving component 4 includes a
hanging ring matching with the hook, and the hook is hung on the
hanging ring for detachable fixed connection.
[0066] The maintenance station further includes a filtering
structure positioned on the end of the detachable part 521
connected to the sewage collection chamber 41. The end of the
detachable part 521 connected to the sewage collection chamber 41
is equipped with the filtering structure, such that hair and
large-sized garbage larger than the holes of the filtering
structure are blocked in the sewage collection chamber 41, thus
preventing the blockage of the pipeline. The filtering structure
can be detachably connected to the end of the detachable part 521
connected to the sewage collection chamber 41.
[0067] As shown in FIG. 10, FIG. 10 is a schematic view of the
cleaning plate.
[0068] The ribbed plate structure of the protrusion part 31 can
include a plurality of ribbed plates positioned at equiangular
intervals with a vertical line as the axis, and the protrusion part
31 can include at least one ribbed plate structure. In the
embodiment, the protrusion part 31 includes two ribbed plate
structures configured to clean two scrubbing components 11 of the
cleaning robot 1 correspondingly, each ribbed plate structure is an
integrated structure, the plurality of ribbed plates can be made in
one piece, which is convenient for installation. The rib plates in
one piece can be fixed on the cleaning plate 32 through fixed
connection such as threaded connection or the like. Optionally, the
ribbed plate structure can be a split-type structure, the plurality
of ribbed plates can be positioned at equiangular intervals with a
vertical line as the axis and is independently mounted on the
cleaning plate 32, the water inlet pipe 61 can be connected to more
than one ribbed plate for spraying water. The ribbed plate
connected to the water inlet pipe 61 is a hollow ribbed plate with
through holes, and the water can be sprayed through the
through-hole. Optionally, the water inlet pipe 61 and the rib plate
can be connected to each other by such as a threaded connection or
clamping connection between a shower head and a water pipe. In
another embodiment, one scrubbing component 11 of the cleaning
robot 1 can be cleaned by a plurality of ribbed plate structures,
or two or more scrubbing components 11 of the cleaning robot 1 can
be cleaned by one ribbed plate structure.
[0069] The cleaning plate 32 includes wheel fixing grooves, and the
wheel fixing groove can be concave with respect to the surface of
the cleaning plate 32, or can also be a fixing groove protruding
upwards from the surface of the cleaning plate 32. In some
embodiments, two wheel fixing grooves are positioned apart from
each other. The distance between the two wheel fixing grooves
corresponds to the distance between the left and right running
wheels of the cleaning robot 1. After the cleaning robot 1 climbs
up the cleaning plate 32, the running wheels are correspondingly
clamped into the two wheel fixing grooves for positioning, so as to
prevent the shaking or moving of the cleaning robot 1.
[0070] The drain holes 321 can be positioned equidistantly in the
width and length directions, or positioned at equal angles with a
vertical axis as the center, or positioned at equal angles in
different radii, or positioned in a honeycomb fashion.
[0071] As shown in FIG. 11, FIG. 11 is a local enlarged view of
part C of FIG. 10.
[0072] The clean water nozzle 62 is positioned in the cleaning
container 3, for example, positioned over or below the scrubbing
component 11 of the cleaning robot 1. The clean water nozzle 62 can
extend out of the cleaning container 3, for example, extending from
the sidewall, the top surface of the cleaning container 3, or from
the cleaning plate 32. Specifically, the clean water nozzle 62 is
positioned on the pipeline or sprayer of the cleaning container 3,
the pipeline can be a threaded hose, and the spray angle and the
distance between the clean water nozzle 62 and the scrubbing
component 11 can be manually adjustable. In some embodiments, the
clean water nozzle 62 extends from the cleaning plate 32. The clean
water nozzle 62 can be positioned on the ribbed plates and faces up
to the scrubbing component 11, which facilitates the integration of
the water feeding mechanism 6 and the protrusion part 31 and makes
the structure compact. The clean water nozzle 62 can also be
positioned on the cleaning plate 32 and face the scrubbing
component 11, and the cleaning plate 32 includes a water inlet
chamber communicating with the water inlet pipe 61. The clean water
nozzle 62 can be a plurality of through holes, which are
equidistant in one direction or in different directions, or are
positioned at an equal angle with a vertical line as the center.
The plurality of through holes can be set in other honeycomb
fashions.
[0073] Each ribbed plate includes a plurality of bumps 311. The
cross-section of each ribbed plate is in curved shape and is convex
in the middle of each ribbed plate. For example, the cross-section
of each ribbed plate is semicircular or semielliptical. The curved
shape makes the scrubbing component 11 be scrubbed more clean, and
the through hole of the ribbed plate communicated with the water
inlet pipe 61 cannot be completely blocked by the scrubbing
component 11, thus solving a common issue that the clean water
nozzle 62 of the protrusion part 31 with a flat top surface tends
to be blocked by the scrubbing component 11. The bumps 311 can also
be replaced by convex bars.
[0074] In another embodiment, the protrusion part 31 is rotatable.
For example, a plurality of ribbed plates is fixed on a rotation
shaft. When rotating, the protrusion part 31 can clean the
non-rotating scrubbing component. For example, when the scrubbing
component 11 of the cleaning robot is fixed at the bottom of the
cleaning robot and cannot be rotated, the rotatable protrusion part
31 can be used for cleaning. In this embodiment, the clean water
nozzle 62 can be arranged below or on the side of the protrusion
part 31.
[0075] As shown in FIG. 2, FIG. 12 is a schematic view of the
cleaning plate according to another embodiment.
[0076] The drain holes 321 can be arranged at any position on the
cleaning plate 32, especially when used in combination with the
dirt receiving component 4 shown in FIG. 7, the number of the drain
holes 321 can be more, the drain holes 321 are positioned at any
position all over the cleaning plate 32. The drain holes 321 are
positioned around the protrusion part 31 as shown in FIG. 6.
[0077] As shown in FIG. 13, FIG. 13 shows a connection of the water
inlet pipe and the magnetic valve.
[0078] The magnetic valve 63 is connected to the water inlet pipe
61. The magnetic valve 63 is configured to control the on or off of
the water inlet pipe 61; the controller is electrically connected
to the magnetic valve 63, and is configured to control the magnetic
valve 63. One end of the water inlet pipe 61 is connected to the
cleaning container 3, and the other end of the water inlet pipe 61
is connected to an external water source such as a tap. The
pressurized water source in the tap can directly flow to the
cleaning container 3 to clean the scrubbing component 11 without
additional power source, which is energy-saving and environmentally
friendly. The arrangement of the magnetic valve 63 and the
controller facilitate the water inlet. The on-off between the water
inlet pipe 61 and the cleaning container 3 can be directly
controlled by the controller.
[0079] The maintenance station further includes two charging
terminals 7. The two charging terminals 7 extend or are exposed out
from the sidewall of the cleaning container 3, and the two charging
terminals 7 corresponds to two charging electrodes of the cleaning
robot 1 in position, such that the cleaning robot 1 can be charged
through the charging terminals 7 while being cleaned. The positions
of the charging terminals 7 and the wheel fixing grooves can be
arranged according to the distance between the charging port and
the running wheel of the cleaning robot 1, as so to simultaneously
cleaning and charging the cleaning robot. The charging terminal 7
and the water feeding mechanism 6 can also be independently
connected to independent switches to control the on or off thereof,
so as to realize the single function of charging or cleaning.
[0080] In assembling the sewage collection chamber 41: the dirt
receiving component 4 is inserted along the slotted guide 21 of the
base 2 until the front baffle plate 43 of the dirt receiving
component 4 is in contact with the front end face of the slotted
guide 21. In this way, the front baffle plate 43, the rear baffle
plate 44, the slotted guide 21 positioned on the sidewall of the
base, the base plate, the guide rails 42 positioned on the base
plate, the sidewalls where the guide rails 42 are positioned, and
the cleaning plate 32 cooperatively form the sewage collection
chamber 41 with the drain holes 321 over the sewage collection
chamber 41.
[0081] When in use, the cleaning robot 1 is positioned in the
cavity 22 of the base 2, and the running wheels of the cleaning
robot 1 are received in the wheel fixing grooves. The scrubbing
component 11 is in contact with the protrusion part 31, and the
charging electrodes of the cleaning robot 1 contact with the
charging terminals 7 on the base 2 to charge the cleaning robot.
The scrubbing component 11 and the water feeding mechanism 6 are
both turned on, the scrubbing component 11 begins to rotate. The
clean water or the clean water mixed with the cleaning liquid flows
to the clean water nozzle 62 via the water inlet pipe 61 and sprays
to the scrubbing component 11 of the cleaning robot 1. The rotating
scrubbing component 11 is scrubbed by the protrusion part 31, and
the dirt is mixed with the clean water or the clean water mixed
with the cleaning liquid to form sewage. The sewage flows into the
sewage collection chamber 41 through the drain holes 321, and is
discharged by the sewage discharger 5.
[0082] After use, the dirt receiving component 4 can be drawn out
along the slotted guide 21 of the base 2 for cleaning, and the dirt
in the dirt receiving component 4 will not remain at the bottom of
the base 2.
[0083] Compared with the related arts, the maintenance station of
the present disclosure includes the base 2, the cleaning container
3 is positioned on the base 2 for cleaning the scrubbing component
11 of the cleaning robot 1, and the dirt receiving component 4
including the sewage collection chamber 41 is positioned below the
cleaning container 3. When in use, the sewage produced in the
cleaning container 3 automatically flows into the sewage collection
chamber 41 by gravity. The sewage collection chamber 41 is
detachably positioned, so the dirt receiving component 4 can be
detached off at any time to remove the accumulated dirt. Compared
with a conventional structure where the sewage in the cleaning
container 3 directly flows into the bottom of the base 2, the dirt
deposits on the bottom of the base 2 is transferred to the dirt
receiving component 4, so as to solve the problem that the dirt on
the mop can easily stay at the bottom of the base 2. Thus, the dirt
receiving component is easy to clean, and the users do not
necessarily squat down or lift the entire maintenance station to
clean the sewage collection chamber 41. The maintenance station of
the present disclosure has the advantages of convenient cleaning,
convenient maintenance, wide application range, no blockage of
pipelines, energy saving and environmental friendliness.
[0084] The above embodiments only express several exemplary
embodiments of the present disclosure, and their descriptions are
relatively specific and detailed, but cannot be interpreted as
limitations on the scope of the present disclosure. It should be
pointed out that, for ordinary technical persons skilled in the
art, a number of deformations and improvements can be made on the
premise of not breaking away from the idea of the present
disclosure, which belong to the protection scope of the present
disclosure.
