Description
FIELD OF THE INVENTION
[0001] The present invention relates to a self-moving floor
treatment device, which belongs to the technical field of the
manufacture of small household electric appliances.
BACKGROUND ART
[0002] Currently, the automatic floor-wiping structure of the
intelligent vacuum cleaner on the market is configured by directly
fixing a cleaning cloth at the bottom of the machine, or attaching
the cleaning cloth on a bottom surface of a water tank and then
fixing the water tank at the bottom of the machine so as to clean
the floor with water. However, when the water tank is used together
with the cleaning cloth, since the cleaning cloth is completely
wetted (the water inside the water tank gradually penetrates into
the cleaning cloth), the friction coefficient between the cleaning
cloth and the floor may increase, and the weight of a part of the
machine body is applied to the cleaning cloth, resulting in an
excessive friction resistance between the machine and the floor,
such that the machine may slip on a watery floor and thus cannot
perform effective cleaning, thereby seriously affecting the work
efficiency of the intelligent vacuum cleaner. Further, when the
intelligent vacuum cleaner climbs up, one end of the water tank,
which is away from the drive wheel, may easily bear against the
floor, making the robot unable to walk.
SUMMARY OF THE INVENTION
[0003] To overcome the deficiencies in the prior art, present
invention aims to provide a self-moving floor treatment device, in
which a water tank is mounted on a machine body base in a floating
manner so as to leave a certain gap therebetween, and the water
tank and the cleaning cloth may float up and down within a certain
range of space, so that the friction force between the cleaning
cloth and the floor is reduced; the machine is effectively
prevented from slipping on the watery floor; the floor cleaning
efficiency is improved; and the obstacle crossing ability of the
machine with the water tank is improved.
[0004] The technical objective of the present invention is realized
through the following technical solutions:
[0005] A self-moving floor treatment device comprises a machine
body base and a water tank, a bottom of the water tank is attached
with a cleaning cloth, and the water tank is connected to a bottom
surface of the machine body base in a manner of floating up and
down.
[0006] Specifically, a floating gap between a top surface of the
water tank and the bottom surface of the machine body base has a
size of 0.5-10 mm.
[0007] In working condition, the cleaning cloth is pressed against
the floor by the gravity of the water tank and the cleaning cloth
themselves.
[0008] More specifically, the machine body base or the water tank
is provided with a guide pillar, and the water tank or the machine
body base is provided with a guide hole correspondingly, which is
fitted around the guide pillar and moves up and down along the
guide pillar. The contact surfaces of the guide pillar and the
guide hole are respectively provided with a rib and a groove so as
to facilitate positioning.
[0009] Further, an elastic member is provided between the machine
body base and the water tank, and the two ends of the elastic
member are positioned on the machine body base and the water tank,
respectively. The elastic member is a leaf spring or a spring.
[0010] In order to reduce the number of times of cleaning and
replacing the cleaning cloth, the outside of the cleaning cloth is
further covered with a disposable cleaning cloth; and the
disposable cleaning cloth covers the peripheral surface of the
water tank and the edges thereof are turned over to the inner side
of the water tank so as to be fixed.
[0011] In conclusion, the present invention provides a self-moving
floor treatment device, wherein, after attaching the cleaning cloth
to the bottom surface of the water tank, the water tank is mounted
on the machine body base in a floating manner so as to leave a
certain gap therebetween. The water tank and the cleaning cloth may
float up and down within a certain range of space. As to the
cleaning cloth, the force actually acted on the floor is the
gravity of the water tank and the cleaning cloth themselves and
does not comprise the gravity of the machine. Therefore, compared
with a common product, the friction force between the cleaning
cloth and the floor is reduced; the machine is effectively
prevented from slipping on the watery floor; the floor cleaning
efficiency is improved; and the obstacle crossing ability of the
machine with the water tank is improved.
[0012] The technical solutions of the present invention now will be
described in detail with reference to the accompanying drawings and
specific embodiments.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
First Embodiment
[0016] FIG. 1 is a diagram of the overall structure of the
self-moving floor treatment device according to the first
embodiment of the present invention; FIG. 2 is a sectional view of
the self-moving floor treatment device according to the first
embodiment of the present invention; and FIG. 3 is an exploded view
of the self-moving floor treatment device according to the first
embodiment of the present invention. As shown in FIGS. 1-3, the
present invention provides a self-moving floor treatment device A
comprising a machine body base 100 and a water tank 200. The bottom
of the water tank 200 is attached with a cleaning cloth 210, and
the water tank 200 is connected to the bottom surface of the
machine body base 100 in a manner of floating up and down. In order
to guarantee that the water tank 200 is able to float to a certain
extent relative to the machine body base 100 and such floating does
not obstruct the self-moving floor treatment device from walking,
the size of the floating gap should meet a certain requirement,
which generally may be 0.5-10 mm. Different physical structures may
be used to enable the water tank 200 to float up and down relative
to the machine body base 100. For example, the machine body base or
the water tank is provided with a guide pillar, and the water tank
or the machine body base is provided with a guide hole
correspondingly, which is fitted around the guide pillar and moves
up and down along the guide pillar. As shown in FIG. 3, in the
present embodiment, such physical structure is configured by a
guide pillar 201 provided on the water tank 200 and a guide hole
111 (as shown in FIG. 1) correspondingly provided on the machine
body base 100. For the purpose of effective positioning, the
contact surfaces of the guide pillar and the guide hole may further
be respectively provided with a rib 202 and a groove (not shown)
for positioning. Further, in order to reduce the number of times of
cleaning and replacing the cleaning cloth 210, the outside of the
cleaning cloth 210 is also covered with a disposable cleaning cloth
220. Specifically, the structure is configured by making the
disposable cleaning cloth 220 cover the peripheral surface of the
water tank 200, and turning over the edges of the disposable
cleaning cloth 220 to the inner side of the water tank 200 so as to
be fixed. In order to be able to achieve effective positioning and
easy replacement, the edges of the disposable cleaning cloth 220
can be used together with a rubber band or an elastic band, and
such effect can also be achieved by a nylon velcro provided on the
edges the disposable cleaning cloth and back of the water tank
correspondingly.
[0017] As shown in FIGS. 1-3, in the present embodiment, since the
water tank 200 is mounted on the machine body base 100 in a
floating manner so as to leave a certain gap therebetween, during
the operation of the self-moving floor treatment device A, the
water tank 200 and the cleaning cloth 210 may float within a
certain range of space under the gravity of the water tank 200 and
the cleaning cloth 210 themselves. That is, they may float in a
direction vertical to the floor. At this point, the cleaning cloth
200 is in contact with the floor, and the force actually acted on
the floor is just the gravity of the water tank and the cleaning
cloth themselves and does not comprise the gravity of the machine
body of the self-moving floor treatment device. Thus, compared with
a common product, the friction force between the cleaning cloth and
the floor is reduced; the machine is effectively prevented from
slipping on the watery floor; and the floor cleaning efficiency is
improved. In addition, when the self-moving floor treatment device
climbs up, since the water tank may float relative to the machine
body base, one end of the water tank is less likely to bear against
the machine body base and to be stuck, which significantly enhances
the climbing ability of the self-moving floor treatment device.
Second Embodiment
[0018] The present embodiment differs from the first embodiment in
that an elastic member is further provided between the water tank
200 and the machine body base 100. The two ends of the elastic
member are positioned on the machine body base 100 and the water
tank 200, respectively, and under the elastic support by the
elastic member, a floating gap is left between the bottom surface
of the machine body base and the outer top surface of the water
tank. The elastic member may be a leaf spring or a spring based on
needs. Obviously, persons skilled in the art may also select other
proper structure according to the actual needs of a specific
structure. For example, the elastic member is fitted around the
guide pillar so as to achieve the elastic connection between the
machine body base and the water tank.
[0019] Similar to the principal of the first embodiment, the
elastic member adopted in the present embodiment enables that,
during the movement of the self-moving floor treatment device A,
the force actually acted on the floor is the gravity of the water
tank and the cleaning cloth themselves, and the pressure between
the cleaning cloth and the floor may be further slightly adjusted
by the elastic force of the elastic member. Therefore, with the use
of the self-moving floor treatment device, the friction force
between the cleaning cloth and the floor may be maintained in an
optimal range, which effectively prevents the slipping phenomenon
from occurring and improves the floor cleaning efficiency.
[0020] The other contents of the present embodiment are the same as
those of the first embodiment, the description of which will be
omitted here.
[0021] In conclusion, the present invention provides a self-moving
floor treatment device, wherein, after attaching the cleaning cloth
to the bottom surface of the water tank, the water tank is mounted
on the machine body base in a floating manner so as to leave a
certain gap therebetween. The water tank and the cleaning cloth may
float up and down within a certain range of space. As to the
cleaning cloth, the force actually acted on the floor is just the
gravity of the water tank and the cleaning cloth themselves and
does not comprise the gravity of the machine. Compared with a
common product, the friction force between the cleaning cloth and
the floor is reduced; the machine is effectively prevented from
slipping on the watery floor; the floor cleaning efficiency is
improved; and the obstacle crossing ability of the machine with the
water tank is improved.
