Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This Application is a national stage application of
PCT/CN2019/105375. This application claims priorities from PCT
Application No. PCT/CN2019/105375, filed Nov. 9, 2019, and Chinese
Patent Application No. 201910706861.4, filed Aug. 1, 2019, the
content of which is incorporated herein in the entirety by
reference.
TECHNICAL FIELD
[0002] The present application relates to the field of vacuum
cleaners, and in particular, to a vacuum cleaner brush head and a
dust collection method.
BACKGROUND
[0003] Vacuum cleaner is a cleaning device that uses negative
pressure to generate suction to remove dirt, and has been used more
and more widely. In the prior art, it is difficult to completely
remove the dust on the surface of an object to be cleaned by means
of suction alone. In order to improve the cleaning effect, a vacuum
cleaner brush head with bristles has appeared in the prior art,
which uses the bristles to scrape the dust to be sucked into a dust
collection port. However, according to the automatic brush head in
the prior art, a type of bristles is generally arranged in a
cylindrical shape, resulting in a high failure rate due to
proneness to tangling by hair; moreover, the acting force is small,
thus it can clean floating dust only but is difficult to clean the
garbage firmly adhered to the floor, so the cleaning effect is
poor. It is very important that the user needs to press the vacuum
cleaner brush head hard towards the floor in the prior art, which
leads to a physical burden for the user, so the user experience is
poor. According to the solution of the prior art, the sweeping area
for accumulated dust is small, and the cylindrical bristles neither
can dispose of garbage of a relatively large size, nor can dispose
of objects such as hair stuck to the floor, so it is hard for the
user to clean and the use experience is bad. It is more important
that, the linkage action between the cylindrical bristles and the
dust collection port makes the two difficult to cooperate
effectively, so there is still much room for improvement in the
dust collection effect.
[0004] On the other hand, some brush heads in the prior art are
provided with water spraying devices, but during use, the water
spraying devices are easy to wet the garbage such as hair on the
floor, resulting in that the garbage is stuck to the floor surface
and very difficult to be sucked up and cleaned. Moreover, moisture
is easily sucked into the dust collection system from the dust
collection port. Once moisture enters the dust collection system,
it is very easy to burn the motor of the dust collection
system.

[0031] A dust collection method, where the vacuum cleaner brush
head according to any one of the foregoing items is used to perform
the following operations:
[0032] starting a negative pressure generation device so that
garbage is sucked away by the dust collection pipe at the dust
collection port;
[0033] starting the wiping plate driving device which is configured
to drive the front wiping plate and the rear wiping plate to move
reciprocally in opposite directions; and
[0034] starting the water spraying assembly according to a preset
time interval and water volume, so that the front wiping plate

plate performs wet piping on the surface to be cleaned.
[0035] In a specific embodiment, the method further includes:
[0036] detecting whether the brush head body is located on the
floor, and shunting down the water spraying assembly when the brush

further includes:
[0037] receiving a control instruction sent by a mobile terminal
for controlling the vacuum cleaner brush head to work, where the
control instruction includes one or more of a water spraying
assembly start and shutdown instruction, a wiping plate driving
device start and shutdown instruction, a negative pressure
generation device start and shutdown instruction, a water spray
time interval, or an air suction amount.
[0038] The present invention at least has the following beneficial
effects:
[0039] According to the vacuum cleaner brush head and the dust
collection method provided by the present invention, in the
cleaning process, the front wiping plate and the rear wiping plate
move reciprocally in opposite directions. Compared with the
cylindrical bristles in conventional vacuum cleaners, the forward
and backward movement of the wiping plates enables the wiping
plates to have a larger cleaning area, and even extend from the
left edge to the right edge of the bottom of the brush head body.
Because the cleaning area is larger, the dust collection cleaning
efficiency can be significantly improved. Moreover, because the
front wiping plate and the rear wiping plate move reciprocally in
opposite directions, the cleaning effect of reciprocal wiping is
significantly improved as compared with the unidirectional rotating
wiping performed by the cylindrical bristles in a conventional
vacuum cleaner. Moreover, by no longer wiping the floor by means of
rolling wiping, the problem in the prior art of hair entanglement
existing in the cylindrical bristles is overcome. Furthermore,
compared with the cylindrical bristles, the cleaning cloth in this
solution may have a greater acting force with the floor, thereby
facilitating the cleaning of garbage firmly adhered to the
floor.
[0040] On the other hand, because the front wiping plate is
provided with a dust passing hole penetrating the upper and lower
ends thereof, the dust collection port is kept overlapping the dust
passing hole. Thus, when the negative pressure generation device is
started so that the garbage enters the dust collection groove of
the front wiping plate, most of the garbage can be sucked away
through the dust collection port before contacting the cleaning
cloth on the front wiping plate, and the remaining dust left on the
floor that has not been cleaned up is subsequently disposed of by
the cleaning cloth on the front wiping plate and the rear wiping
plate. In addition, the cleaning cloth on the front wiping plate
can push garbage of a relatively large size and weight forward to a
region where the dust collection port is located, so that the
garbage is sucked in from the dust collection port. That is, in the
present invention, the garbage is directionally pushed to the dust
collection port by means of the front wiping plate, and the two
achieve efficient linkage dust collection cleaning. Compared with
combinations in the prior art of a rolling brush and a dust
collection port and of cylindrical bristles and a dust collection
port which work independent of each other or have poor linkage, the
present invention has a significant technological progress, and the
significantly improved dust collection cleaning effect brought
about by this linkage is difficult to predict in the prior art.
[0041] Further, when the dust collection pipe performs a dust
collection operation, the air in the dust collection groove is
pumped out to form a negative pressure space, and under the action
of an air pressure difference, the cleaning cloth on the wiping
plates is in close contact with the floor. On the one hand, the
vacuum cleaner brush head can be in close contact with the floor
without being pressed hard by the user, and on the other hand, the
friction between the cleaning cloth and the floor is significantly
enhanced. The garbage firmly adhered to the floor can be removed.
This cannot be implemented by the prior art, and thus a significant
progress is achieved.
[0042] Further, the front wiping plate is provided with a dust
passing hole penetrating the upper and lower ends thereof, which
can also significantly reduce the space occupation at the bottom of
the brush head body by the dust collection portion, thereby
increasing the proportion of the area of the cleaning cloth on the
wiping plate at the bottom of the brush head body.
[0043] Further, the water spraying port of the water spraying
assembly is provided at the bottom of the brush head body and
located between the front wiping palate and the rear wiping plate.
Therefore, in the traveling process of the brush head, the front
wiping plate is in contact with the dry floor, and the rear wiping
plate is in contact with the wet floor, so that the front wiping
plate performs dry wiping on the surface to be cleaned to implement
the cleaning of garbage such as floating dust, and the rear wiping
plate performs wet wiping on the surface to be cleaned. Compared
with simple dry wiping or simple wet wiping in the prior art, the
brush head can dispose of multiple types of garbage, thereby
achieving a better overall cleaning effect. Thus, the all-in-one
cleaning function of dust collection, dry wiping and wet wiping is
implemented, and the effects of dust collection and cleaning are
further significantly improved.
[0044] Further, because the water spraying port is provided between
the front wiping plate and the rear wiping plate, the dust
collection port and the water spraying port are separated by the
cleaning cloth on the front wiping plate to avoid the possibility
that a cleaning liquid sprayed from the water spraying port enters
the dust collection port, thereby preventing the motor of the dust
collection system from damage by ingress of water. That is, an
ingenious structure is used to improve both the cleaning effect and
the safety.
[0045] In conclusion, the present invention can achieve the
technical effects of significantly increasing the cleaning area and
improving the cleaning effect of the vacuum cleaner brush head, and
has prominent substantive features and a remarkable progress as
compared with the existing ones. Moreover, it should be noted that
although the technical effects of the foregoing technical features
are described in paragraphs, the parts are not separate but a
coordinated and matched overall technical solution.

advantages of the present invention to be more apparent and

DETAILED DESCRIPTION
Embodiment 1
[0066] This embodiment provides a vacuum cleaner brush head 1. The
vacuum cleaner brush head 1 may be used as a brush head of a vacuum
cleaner.
[0067] As shown in FIG. 1 to FIG. 3, the vacuum cleaner brush head
1 includes a brush head body 2, a front wiping plate 4, a rear
wiping plate 5, a wiping plate driving device, and a water spraying
assembly. A dust collection pipe is provided in the brush head body
2; the dust collection pipe has a dust collection port 6 formed on
the front side of the bottom of the brush head body 2; the front
wiping plate 4 and the rear wiping plate 5 are provided at the
bottom of the brush head body 2, respectively; cleaning cloth is
provided on the front wiping plate 4 and the rear wiping plate 5,
respectively; the wiping plate driving device is provided in the
brush head body 2; a water spraying port of the water spraying
assembly is provided on the bottom of the brush head body 2 and
located between the front wiping plate 4 and the rear wiping plate
5. The wiping plate driving device is transmittingly connected to
the front wiping plate 4 and the rear wiping plate 5, and is
configured to drive the front wiping plate 4 and the rear wiping
plate 5 to move reciprocally in opposite directions.
[0068] The front wiping plate 4 is provided with a dust passing
hole 44 penetrating the upper and lower ends thereof, and the dust
passing hole 44 is configured to have a preset size, so that the
dust collection port 6 always overlaps the dust passing hole 44
when the front wiping plate 4 moves reciprocally. Specifically, as
shown in FIG. 2, in the forward or backward direction of the front
wiping plate 4, the width of the dust passing hole 44 is greater
than the width of the dust collection port 6 by a preset threshold,
to keep the dust collection port 6 overlapping the dust passing
hole 44 when the dust passing hole 44 moves reciprocally along with
the front wiping plate 4. The specific value of the preset
threshold value can be selected by a person skilled in the art
according to the size of one of the dust collection port 6 and the
dust passing hole 44, and is a variable number, as long as the dust
collection port 6 is kept overlapping the dust pass hole 44 when
the dust passing hole 44 moves reciprocally along with the front
wiping plate 4. No more examples are listed in this embodiment one
by one. It should be noted that, in another embodiment, in the
forward or backward direction of the front wiping plate, the width
of the dust passing hole may be less than the width of the dust
collection port by the present threshold, to keep the dust
collection port overlapping the dust passing hole when the dust
passing hole moves reciprocally along with the front wiping
plate.
[0069] Specifically, the brush head body 2 is formed into a shell
structure in order to mount the front wiping plate 4, the rear
wiping plate 5, the wiping plate driving device, the water spraying
assembly, the dust collection pipe, and other accessories. In this
embodiment, the dust collection pipe is connected to a negative
pressure generation device in a vacuum cleaner system by means of a
joint and an outer tube 25. When the negative pressure generation
device is started, a negative pressure is generated at the dust
collection port 6 to suck garbage such as dust.
[0070] Preferably, the front wiping plate 4 and the rear wiping
plate 5 are respectively long plate-shaped structures, which even
extend from the left edge of the bottom of the brush head body 2
all the way to the edge. Therefore, the front wiping plate 4 and
the rear wiping plate 5 significantly increase the effective
cleaning area of the cleaner brush head 1 as compared with the
cylindrical wiping plates in the prior art. Preferably, the
cleaning cloth on the front wiping plate 4 and the rear wiping
plate 5 is respectively detachably mounted, for example, the
cleaning cloth is respectively bonded to the front wiping plate and
the rear wiping plate 5 by means of nylon-like buckles.
[0071] FIG. 6 to FIG. 9 show a preferred wiping plate driving
device. The wiping plate driving device includes a crankshaft 20, a
first connecting rod 18, and a second connecting rod 19. The
crankshaft 20 includes a crankshaft rod 201, and a first journal
202 and a second journal 203 formed on the crankshaft rod 201; one
end of the first connecting rod 18 is rotatably sleeved on the
first journal 202, and the other end is hingedly connected to the
top of the front wiping plate 4; one end of the second connecting
rod 19 is rotatably sleeved on the second journal 203, and the
other end is hingedly connected to the top of the rear wiping plate
5. That is, the crankshaft 20, the first connecting rod 18, and the
front wiping plate 4 constitute a group of crank connecting rod
mechanisms, and the crankshaft 20, the second connecting rod 19,
and the rear wiping plate 5 constitute the other group of crank
connecting rod mechanisms. In order to enable the crankshaft 20 to
rotate, the wiping plate driving device further includes a driving
motor 16 and a transmission mechanism provided in the brush head
body 2; the driving motor 16 drives the crankshaft 20 to rotate by
means of a rotating mechanism, where the transmission mechanism
includes a synchronous belt, an eddy current worm gear box, or
other structure types.
[0072] Preferably, the shaft axis of the first journal 202, the
shaft axis of the second journal 203, and the rotation axis of the
crankshaft rod 201 are coplanar; and the distance between the shaft
axis of the first journal 202 and the rotation axis of the
crankshaft rod 201 is equal to the distance between the shaft axis
of the second journal 203 and the rotation axis of the crankshaft
rod 201. Therefore, when the crankshaft 20 rotates in one
direction, it drives the front wiping plate 4 and the rear wiping
plate 5 to move reciprocally in opposite direction.
[0073] Preferably, the wiping plate driving device is further
configured to keep the crankshaft 20 self-balanced when driving the
front wiping plate 4 and the rear wiping plate 5 to move
reciprocally in opposite directions. Specifically, by presetting
specific parameter values such as sizes, weights, and shapes of the
first journal 202, the second journal 203, the first connecting rod
18, the second connecting rod 19, the front wiping plate 4, and the
rear wiping plate 5, the crankshaft 20 is kept self-balanced in a
rotation process. Therefore, the entire vacuum cleaner brush head 1
can be kept stable when the front wiping plate 4 and the rear
wiping plate 5 move reciprocally in opposite directions, to avoid
the generation of unnecessary vibration, so that noise and the wear
of the wiping plate driving device can be significantly
reduced.
[0074] In this embodiment, the number of the water spraying port is
one or multiple, and preferably is multiple. FIG. 2 shows a case
where the number of the water spraying ports is two. The two water
spraying ports are both provided on the bottom of the brush head
body 2 and located between the front wiping plate 4 and the rear
wiping plate 5. Specifically, the water spraying assembly further
includes a water tank 12, a pumping device 17, and a water supply
pipe provided in the brush head body 2. The water tank 12 is
connected to each water spraying port by means of the water supply
pipe. A water pump is provided in the water supply pipe for
pressurizing the cleaning liquid in the water tank 12 and then
spraying same from the water spraying port.
[0075] As shown in FIG. 9 to FIG. 12, the water tank 12 includes a
tank body 121, a tank cover 122, and a water separation pad 123.
The tank cover 122 is provided at the top of the tank body 121. The
lower part of the tank body 121 has a water outlet. The water
separation pad 123 is provided in the tank body 121 and divides the
tank body 121 into an upper cavity 124 and a lower cavity 125. The
lower cavity 125 is configured to store water. The height of the
central region of the water separation pad 123 is less than that of
the edge region, and the central region of the water separation pad
123 has a water injection port 131 for injecting water into the
lower cavity 125. The tank cover 122 is configured to open or close
the water injection port 131.
[0076] Preferably, the height of the water separation pad 123
decreases continuously and smoothly from the edge region to the
central region.
[0077] Preferably, the bottom of the tank body 121 is recessed
inwardly to form an accommodating groove 130.
[0078] Preferably, the water separation pad 123 is an elastic body,
such as a silicone water separation pad 123 having elasticity.
[0079] The bottom of the brush head body 126 is provided with a
nozzle, and the nozzle communicates with a water outlet by means of
a water delivery pipe. The water pump is configured to pump the
cleaning fluid in the lower chamber 125 to the nozzle for spraying.
Specifically, the water pump is connected into the water delivery
pipe, and when the water pump is started, pressure is generated to
pump the cleaning fluid in the water tank 12.
[0080] In this embodiment, the edge region of the water separation
pad 123 has an annular protrusion 127 protruding downwardly and
extending around the central region, the top of the tank body 121
has a first annular groove 132, and the annular protrusion 127 is
mounted in the first annular groove 132. The upper surface of the
annular protrusion 127 is recessed inwardly to form a second
annular groove 133. The upper surface of the brush head body 126
has an opening, and the tank cover 122 is openably mounted at the
opening. The brush head body 126 has a cylindrical protrusion 128
protruding downwardly on the inner surface at the opening. The
cylindrical protrusion 128 is mounted in the second annular groove
133, so that the tank cover 122, the cylindrical protrusion 128,
and the tank body 121 enclose a closed space.
[0081] Preferably, the tank cover 122 includes a cover plate 1221
and a cylinder body 1222 connected as an integral whole. The cover
plate 1221 exposes the upper surface of the brush head body 126.
The cylinder body 1222 is inserted into the opening. An elastic
seal ring 129 is sleeved on the cylinder body 1222, and the elastic
seal ring 129 abuts against the inner wall of the opening.
[0082] In this embodiment, the cleaning device further includes a
wiping plate, a wiping plate driving device, and a dust collection
pipe. The dust collection pipe is provided in the brush head body
126, and has a dust collection port formed on the bottom of the
brush head body 126. The wiping plate is provided at the bottom of
the brush head body 126. The bottom of the wiping plate is provided
with cleaning cloth. The wiping plate driving device is provided in
the brush head body 126 to drive the wiping plate to move.
[0083] Therefore, on the one hand, the water separation pad 123 may
be used to separate the cleaning fluid storage in the lower cavity
125 from the upper cavity 124, to avoid the possibility of water
leakage caused by the impact on the tank cover 122 due to the
sloshing of the cleaning liquid in the cleaning device during high
speed vibration or movement. Even if a small amount of the cleaning
liquid overflows to the top of the water separation pad 123 during
sloshing, there is little cleaning liquid that can contact the tank
cover 122 due to a certain distance between the water separation
pad 123 and the tank cover 122. Moreover, because the height of the
central region of the water separation pad 123 is less than that of
the edge region, even if a small amount of the cleaning liquid
overflows to the top of the water separation pad 123 during
sloshing, the cleaning liquid can also be collected into the water
injection port 131 and fall into the lower cavity 125 in time under
the action of its own gravity. Moreover, during the water injection
process, it is unnecessary to completely align the water injection
port 131, and the cleaning liquid can be autonomously collected
into the water injection port 131 and fall into the lower cavity
125, thereby providing the efficiency of water injection and
preventing the cleaning liquid from being spilled during the water
injection process.
[0084] In addition, because the water separation pad 123 can
skillfully prevent water leakage, there is no need to completely
seal the tank cover 122, so that the water tank can be supplemented
with air in the process of supplying water to the outside, to
eliminate the air pressure difference between the inside and
outside of the water tank, which is convenient for the water
spraying system to smoothly output the cleaning liquid in the water
tank.
[0085] According to the vacuum cleaner brush head 1 provided by
this embodiment, in the cleaning process, the front wiping plate 4
and the rear wiping plate 5 move reciprocally in opposite
directions. Compared with the unidirectional rotating wiping
performed by the cylindrical bristles in a conventional vacuum
cleaner, the cleaning effect of reciprocal wiping is significantly
improved. Moreover, by no longer wiping the floor by means of
rolling wiping, the problem in the prior art of hair entanglement
existing in the cylindrical bristles is overcome. Furthermore,
compared with the cylindrical bristles, the cleaning cloth in this
solution may have a greater acting force with the floor, thereby
facilitating the cleaning of garbage firmly adhered to the
floor.
[0086] On the other hand, because the front wiping plate 4 is
provided with a dust passing hole 44 penetrating the upper and
lower ends thereof, and the dust passing hole 44 is configured to
have a preset size, so that the dust collection port 6 always
overlaps the dust passing hole 44 when the front wiping plate 4
moves reciprocally. Thus, when the negative pressure generation
device is started so that the garbage enters the dust pass hole 44
of the front wiping plate 4, most of the garbage can be sucked away
through the dust collection port 6 before contacting the cleaning
cloth on the front wiping plate 4, and the remaining dust left on
the floor that has not been cleaned up is subsequently disposed of
by the cleaning cloth on the front wiping plate 4 and the rear
wiping plate 5. In addition, the cleaning cloth on the front wiping
plate can push garbage of a relatively large size and weight
forward to a region where the dust collection port 6 is located,
i.e., the cleaning cloth on the front wiping plate 4 can push
garbage such as dust and hair forward to the region where the dust
collection port 6 is located, so that the garbage is sucked in from
the dust collection port 6. That is, in this embodiment, the
garbage is directionally pushed to the dust collection port 6 by
means of the front wiping plate 4, and the two achieve efficient
linkage dust collection cleaning. Compared with combinations in the
prior art of a rolling brush and a dust collection port 6 and of
cylindrical bristles and a dust collection port 6 which work
independent of each other or have poor linkage and thus are
difficult to convey the garbage on the floor to the dust collection
port 6, this embodiment has a significant technological progress,
and the significantly improved dust collection cleaning effect
brought about by this linkage is difficult to predict in the prior
art. Further, when the dust collection pipe performs a dust
collection operation, the air in the dust collection groove 42 is
pumped out to form a negative pressure space, and under the action
of an air pressure difference, the cleaning cloth on the wiping
plate is in close contact with the floor. On the one hand, the
vacuum cleaner brush head can be in close contact with the floor
without being pressed hard by the user, and on the other hand, the
friction between the cleaning cloth and the floor is significantly
enhanced, thus the garbage firmly adhered to the floor can be
removed. This cannot be implemented by the prior art, and thus a
significant progress is achieved.
[0087] Further, the front wiping plate 4 is provided with a dust
passing hole 44 penetrating the upper and lower ends thereof, which
can also significantly reduce the space occupation at the bottom of
the brush head body 2 by the dust collection portion 6.
[0088] In conclusion, this embodiment can achieve the technical
effects of significantly increasing the cleaning area and improving
the cleaning effect of the vacuum cleaner brush head 1, and has
prominent substantive features and a remarkable progress as
compared with the existing ones. Moreover, it should be noted that
although the technical effects of the foregoing technical features
are described in paragraphs, the parts are not separate but a
coordinated, matched, and linked overall technical solution.
[0089] This embodiment further provides a dust collection method,
where the vacuum cleaner brush head 1 in this embodiment is used to
perform the following operations:
[0090] starting a negative pressure generation device so that
garbage is sucked away by the dust collection pipe at the dust
collection port 6;
[0091] starting the wiping plate driving device which is configured
to drive the front wiping plate 4 and the rear wiping plate 5 to
move reciprocally in opposite directions; and
[0092] starting the water spraying assembly according to a preset
time interval and water volume, so that the front wiping plate 4
performs dry wiping on a surface to be cleaned, and the rear wiping
plate 5 performs wet piping on the surface to be cleaned.
[0093] therefore, in the traveling process of the vacuum cleaner
brush head 1, the front wiping plate 4 is in contact with the dry
floor, and the rear wiping plate 5 is in contact with the wet
floor, so that the front wiping plate 4 performs dry wiping on the
surface to be cleaned, and the rear wiping plate 5 performs wet
wiping on the surface to be cleaned. Moreover, because the front
wiping plate 4 performs dry wiping, it rubs and pushes garbage such
as dust in a relatively dry state, and thus is easier to push the
garbage of a relatively large size to the dust suction port 6,
while the small particles of dry dust are lifted from the floor and
then sucked in by the dust collection port 6. In the prior art,
simple dry wiping cannot achieve the effect of cleaning the floor,
resulting in that the cleaning effect is far inferior to that of
this embodiment. In the prior art, simple wet wiping has a poor
dust collection capability, and the dust is still on the floor
after the moisture evaporates. Because the water spraying port is
in the front, it is easy to wet the hair on the floor, and it is
difficult to suck up and clean up the hair adhered to the floor, so
the cleaning effect is also far inferior to that of this
embodiment. Therefore, the solution in this embodiment implements
the all-in-one cleaning function of dust collection, dry wiping and
wet wiping, and further significantly improves the effects of dust
collection and cleaning.
[0094] As shown in FIG. 4 to FIG. 8 and FIG. 13, the top of the
front wiping plate 4 is transmittingly connected to the wiping
plate driving device. Preferably, the top of the front wiping plate
4 is provided with a connecting base 47, a hinge shaft penetrates
the connecting base 47, and the first connecting rod 18 rotatably
penetrates the hinge shaft. Correspondingly, the top of the rear
wiping plate 5 is transmittingly connected to the wiping plate
driving device. Preferably, the top of the rear wiping plate 5 is
provided with a connecting base 47, a hinge shaft penetrates the
connecting base 47, and the second connecting rod 19 rotatably
penetrates the hinge shaft.
[0095] As shown in FIG. 2 to FIG. 5, the bottom of the front wiping
plate 4 has a dust collection groove 42 and a cleaning cloth
mounting portion 43; the front wall 41 of the dust collection
groove is located at the bottom front edge of the front wiping
plate 4, and the rear wall 46 of the dust collection groove is
connected to the cleaning cloth mounting portion 43; and the dust
passing hole 44 is provided in the dust collection groove 42.
Because the components of the front wiping plate 4 include the dust
collection groove 42, the cleaning cloth on the cleaning cloth
mounting portion 43 at the rear side of the dust collection groove
42 first pushes the garbage into the dust collection groove. Then,
the garbage is collected to the dust passing hole 44 in the dust
collection groove 42 and then sucked away by the dust collection
port 6. Therefore, compared with the prior art, the area of the
effective suction region of the dust collection port 6 can be
significantly increased, and the dust collection area of the vacuum
cleaner brush head 1 can be increased, thereby improving the
cleaning efficiency.
[0096] As shown in FIG. 2 to FIG. 4, the front wall 41 of the dust
collection groove has a plurality of notches 45 arranged at
intervals, and each of the notches 45 respectively communicates
with the dust collection groove 42. In this embodiment, because the
notch 45 on the front wall 41 of the dust collection groove matches
the dust collection groove 42, so that when the vacuum cleaner
brush head 1 travels or the dust collection pipe works, the garbage
of a relatively large size can enter the dust collection groove 42
through the notch 45, and then is collected to the dust passing
hole 44 in the dust collection groove 42 and then sucked away by
the dust collection port 6. Therefore, the effects of dust
collection and cleaning for the large of a relatively large size
are significantly improved.
[0097] Preferably, the dust collection groove 42 extends from the
middle to both sides at the bottom front edge of the front wiping
plate 4, and occupies more than half of the length of the bottom
front edge of the front wiping plate 4. Therefore, the dust
collection and cleaning area of the vacuum cleaner brush head 1 can
be further increased.
[0098] In this embodiment, the number of the dust collection port 6
is one or multiple, and the number of the dust passing hole 44 is
one or multiple. When the number of the dust collection ports 6 is
multiple, the dust passing holes 44 correspond one-to-one to the
dust collection ports 6 or one of the dust passing holes 44
overlaps a plurality of the dust collection ports 6. That is, one
dust passing hole 44 overlaps one dust collection port 6, or one
dust passing hole 44 overlaps a plurality of dust collection ports
6.
[0099] Preferably, the width of the region of the dust collection
groove 42 not provided with the dust passing hole 44 is less than
the width of the dust passing hole 44. Thus, the area of the
cleaning cloth mounting portion 43 may be larger, and thus the
cleaning area is increased.
[0100] Preferably, at least one group of guide devices is provided
between the front wiping plate 4 and the bottom of the brush head
body 2. More preferably, the guide devices include a roller 10, a
roller base 8, a guide rail bar 9, and a guide rail base 11; the
roller base 8 is fixed on one of the front wiping plate 4 and the
brush head body 2; the roller 10 is rotatably mounted on the roller
base 8, and is in rolling contact with the other of the front
wiping plate 4 and the brush head body 2; the guide rail base 11 is
fixed on one of the front wiping plate 4 and the brush head body 2,
and the guide rail bar is fixed on the other of the front wiping
plate 4 and the brush head body 2; the guide rail base 11 is
configured to limit the moving direction of the guide rail bar
9.
[0101] Preferably, at least one group of guide devices is provided
between the rear wiping plate 5 and the bottom of the brush head
body 2. More preferably, the guide devices include a roller 23, a
roller base 24, a guide rail bar 22, and a guide rail base (not
shown); the roller base is fixed on one of the rear wiping plate 5
and the brush head body 2; the roller is rotatably mounted on the
roller base, and is in rolling contact with the other of the rear
wiping plate 5 and the brush head body 2; the guide rail base is
fixed on one of the rear wiping plate 5 and the brush head body 2,
and the guide rail bar is fixed on the other of the rear wiping
plate 5 and the brush head body 2; the guide rail base is
configured to limit the moving direction of the guide rail bar.
[0102] Preferably, the guide rail base includes a first base body
and a second base body, and the guide rail bar penetrates a gap
between the first base body and the second base body.
[0103] Preferably, the water spraying port of the water spraying
assembly is provided with a nozzle 7, and the nozzle 7 is
detachably mounted at the bottom of the brush head body 2.
[0104] In this embodiment, the dust collection pipe includes an
internal pipe 13 and a flexible joint; the internal pipe 13 is
located in the brush head body 2 and one end of the internal pipe
13 is connected to the dust collection port 6; the other end of the
internal pipe is inserted into the flexible joint; the flexible
joint is fixed on the brush head body 2.
[0105] FIG. 6 and FIG. 13 to FIG. 14 show a preferred flexible
joint. The flexible joint includes a first sleeve 14, a second
sleeve 3, and an outer tube 25; the first end of the first sleeve
14 is inserted into the brush head body 2, and the second end of
the first sleeve 14 is hingedly connected to the second sleeve 3;
the outer tube 25 is sleeved in the second sleeve 3; the internal
pipe 13 passes through the first sleeve 14 and then is inserted
into the outer tube 25; the outer tube 25 and the second sleeve 3
are locked by a snap lug 26. Therefore, the flexible connection of
the outer tube 25 of the dust collection pipe in the vacuum cleaner
brush head 1 is implemented, and quick assembly and disassembly are
facilitated.
[0106] Preferably, a wire plug 27 is fixed between the outer tube
25 and the second sleeve 3, and the wire plug 27 passes through the
second sleeve 3 and the first sleeve 14.
[0107] In this embodiment, the brush head body 2 is further
preferably provided with a position sensor configured to detect
whether the brush head body 2 leaves the floor. The dust collection
method further includes:
[0108] detecting whether the brush head body 2 is located on the
floor, and shunting down the water spraying assembly when the brush
head body 2 leaves the floor.
[0109] In this embodiment, the dust collection method further
includes:
[0110] receiving a control instruction sent by a mobile terminal
for controlling the vacuum cleaner brush head 1 to work, where the
control instruction includes one or more of a water spraying
assembly start and shutdown instruction, a wiping plate driving
device start and shutdown instruction, a negative pressure
generation device start and shutdown instruction, a water spray
time interval, or an air suction amount. Therefore, wireless
intelligent control of the vacuum cleaner brush head 1 can be
implemented by means of devices such as a mobile phone.
Embodiment 2
[0111] This embodiment provides a vacuum cleaner brush head 1. The
vacuum cleaner brush head 1 may be used as a brush head of a vacuum
cleaner. Compared with Embodiment 1, the main differences of this
embodiment are as follows:
[0112] As shown in FIG. 16, the rear wall 46 of the dust collection
groove has a plurality of toothed blades, and the cutting edges of
the toothed blades face the dust collection groove 42. The toothed
blades include triangular teeth, trapezoidal teeth, comb teeth, and
so on.
[0113] Therefore, when encountering garbage such as hair, the
toothed blades may first shovel the garbage, so that the garbage is
sucked away through the dust collection port 6. The hair suction
effect can be improved, and the situation in which the hair has
been caught under the cleaning cloth before the hair is sucked into
the dust collection port 6 during hair suction is eliminated or
reduced, thereby further improving the cleaning effect.
[0114] Preferably, as shown in FIG. 17, a transition portion
between the cleaning cloth mounting portion 43 and the rear wall 46
of the dust collection groove protrudes toward the working surface
with respect to the cleaning cloth mounting portion 43, and the
toothed blades are formed on the protruding transition portion.
[0115] Other features in this embodiment are the same as those in
Embodiment 1. Details are not described herein again.
[0116] The foregoing disclosure is merely several specific
implementation scenarios of the present invention, but the present
invention is not limited thereto. Any change conceivable by a
person skilled in the art shall fall within the scope of protection
of the present invention.
