DETAILED DESCRIPTION OF THE PRESENT INVENTION
[0018] The technical content, structural features, objectives, and
effects of the present invention are described in detail with
reference to the embodiments and attached drawings.
[0019] See FIG. 1. The present invention provides a water-saving
toilet bowl, comprising a toilet bowl body 1 and a water tank 2
disposed on toilet bowl body 1. The toilet bowl body 1 is provided
with a flushing water chamber 11. The flushing water chamber 11 is
connected with water tank 2. Water tank 2 is provided with a switch
21. A flushing water value is disposed between the water tank 2 and
the flushing water chamber 11. The switch 21 controls the opening
and closing of the flushing water valve to realize flushing of the
toilet bowl.
[0020] The drain pipe 111 of the flushing water chamber 11 is
connected with an outside sewage pipe through a water-saving
device. The water-saving device comprises a case, a hose 4, and a
valve component which controls the closing and opening of hose
4.
[0021] The valve component comprises a rotor 51, a rotating shaft
52, and a first pressing member 53. Hose 4 is disposed in the case
in an inclined way; one end of hose 4 is connected with the drain
pipe 111, while the other end is connected with the outside sewage
pipe. The rotating shaft 52 is disposed on the case. The rotor 51
is rotationally disposed on the rotating shaft 52. The first
pressing member 53 is disposed at the front end of the rotor 51.
The first pressing member 53 presses hose 4 to implement closing
and opening of hose 4 when the rotor 51 rotates.
[0022] Hose 4 is disposed in an inclined way and is connected with
the drain pipe 111 and the outside sewage pipe. When sewage in the
flushing water chamber 11 is flushed away, the sewage and the water
are directly discharged into the outside sewage pipe through the
inclined hose 4. Different from the traditional toilet bowl, the
drainage is downward instead of upward, and the sewage can be
easily flushed away using little water.
[0023] Wherein, the outside sewage pipe can be disposed in many
ways. In one embodiment of the present invention, the outside
sewage pipe is a lower sewage pipe 31 or a rear sewage pipe 32. The
specific type of the sewage pipe is disposed upon the specific
installation position of the toilet bowl.
[0024] Specifically, hose 4 is not limited in material by the
present invention, and preferably, is a silicone hose. Of course,
the present invention does not limit the specific material of hose
4.
[0025] Wherein, this application provides preferable embodiments
for the installation and fixation of hose 4. The end of hose 4 is
connected and fixed with drain pipe 111 and the outside sewage pipe
is fixed by a ring hoop. Specifically, the two ends of hose 4 are
respectively provided with fixing slots that extend in the
circumference; the water-saving device is also provided with a ring
hoop; and the ring hoop is disposed in the fixing slots to fix hose
4 on drain pipe 111 and the sewage pipe. The fixing slots further
limit the axial movement of the ring hoop. The fixation is firm;
the dismantling is convenient; and the use is simple.
[0026] The toilet bowl body 1 is provided with a case inside, or
the water close body 1 itself is the case. The case conducts the
function of fixing rotating shaft 52. Rotor 51 is rotationally
disposed on rotating shaft 52. In this embodiment, rotor 51 is
composed of rotating plates which are disposed parallel to each
other; the middle parts of the rotating plates have rotating holes
through which rotating shaft 52 penetrates through. In this
embodiment, the first pressing member 53 is a pressing rod; the two
ends of the pressing rods are respectively connected with the two
rotating plates; and hose 4 extends through the space between the
pressing rod and the rotating shaft 52. When the rotator 51 rotates
towards hose 4 along the pressing rod 4, the pressing rod presses
hose 4 to reduce the cross section of hose 4 and continuously
rotates to close hose 4 and in such circumstances, the rotator 51
rotates in the reverse direction to open hose 4. The rotor 51 is
shaped like a rocker on the rotating shaft 52, alternatively
controlling the opening and closing of hose 4.
[0027] The rotor 51 in the rocker mode in one embodiment is
specially as follows: the rotor 51 is connected with a drive rope 6
which pulls the rotor 51 to rotate; and the drive rope 6 is linked
with a switch 21. In the normally unused situation, hose 4 is
closed, and in such circumstances, the first pressing member 53
presses hose 4. After use of the toilet bowl, press the flushing
switch 21 on the water tank 2, then the drive rope 6 drives the
rotor 51 to rotate, the flushing water valve opens, the water tank
2 flushes the flushing water chamber 11, and then hose 4 opens to
drain the sewage.
[0028] The rotor 51 in the rocker mode in another embodiment is as
follows: the drive rope 6 is connected to the rear end of the rotor
51; the water-saving device is also provided with a reset spring 7;
one end of the reset spring 7 is connected to the rear end of the
rotor 51, while the other end is fixed on the case.
[0029] When the toilet bowl is not used, the first pressing member
53 closes hose 4 and the spring is at the normal position. When the
toilet bowl is flushed in use, press the switch 21 for flushing
while the drive rope 6 pulls the rotor 51 to rotate to open the
hose 4 so as to drain the sewage. When the toilet bowl is not used,
the force acting on the drive rope 6 disappears, and the rotor 51
resets to the original position by the effect of the reset spring
7.
[0030] The outer side of the water tank 2 can be provided with a
housing through which the drive rope 6 can penetrate, ensuring that
the entire toilet bowl has a beautiful appearance.
[0031] Furthermore, to valid the situation that hose 4 is entire
bent and fails to close when pressed by the first pressing member
53, in this embodiment, the case is provided with a first fixing
block 81. The first fixing block 81 is disposed on the other side
of hose 4 relative to the first pressing member 53 and pressed
against hose 4. When the first pressing member 53 presses hose 4,
the movement of hose 4 is limited by the effect of support of the
first fixing block 81, thus realizing the closing and opening of
hose 4.
[0032] When the toilet bowl is not used, hose 4 is closed, which
means that water is not discharged into the sewage pipe. If the
toilet bowl leaks water, water will flow into the flushing water
chamber 11 without stop and finally overflow out of the toilet
bowl. To avoid such situation, in this embodiment, the water-saving
device also comprises a siphon 9. The siphon 9 is disposed on hose
4 in a reverse "U" shape. The peak of the reverse "U"-shaped siphon
9 disposed is lower than the toilet bowl body 1 but higher than the
water level in the flushing water chamber 11. The siphon 9 may have
a smaller inner diameter;
[0033] The siphon has two functions. One is to generate an
absorption force which generates siphonage through the siphon to
continuously bring away water (or air) in the toilet bowl when the
sewage hose is sealed and the sewage in the lower sewage pipe is
pulled downward continuously, thus ensuring smooth sewage
discharge.
[0034] The other is to prevent water leakage. In the case that hose
4 is closed, when the toilet bowl leaks water and the water level
is higher than the peak of siphon 9, water flows out from siphon 9
by the effect of the pressure difference. Meanwhile, some sensors
can be installed to prompt the users.
[0035] Moreover, siphon 9 is closed when hose 4 is used, avoiding
the situation that the sewage is shunted by siphon 9, causes
smaller flushing force of hose 4 and results in water waste.
Meanwhile, the sewage is also prevented from being clamped in
siphon 9 to cause failure of anti-leakage. Therefore, in this
embodiment, the rotor 51 also extends to form a rotating end 54.
The top of rotating end 54 is provided with a second pressing
member 55. The second pressing member 55 presses siphon 9 to
implement closing and opening of siphon 9 when rotor 51 rotates. In
such circumstances, the connecting plates are trifurcate plates,
and the principle is similar to that of the first pressing member
53 and therefore is not repeatedly described. It should be noted
that hose 4 and siphon 9 are alternatively to be opened and closed,
which means that when hose 4 is open, siphon 9 is closed, while
when hose 4 is closed, siphon 9 is open. Therefore, when the first
pressing member 53 is reset and hose 4 is pressed by the effect of
reset spring 7, the second pressing member 55 turns to the
direction away from siphon hose 4.
[0036] In this embodiment, the case is provided with a second
fixing block 82. The second fixing block 82 is disposed on the
other side of siphon 9 relative to the second pressing member 55.
In another embodiment, the first fixing block 81 and the second
fixing block 82 are a whole body.
[0037] In this embodiment, one end of hose 4 close to the sewage
pipe is provided with a valve 41 which allows the fluid to flow in
one direction. Valve 41 functions as a one-way valve. When
discharged, the water flushes open the opening in the middle part
of valve 41. When the toilet bowl is not used, the opening is
closed to prevent the terrible smell in the sewage pipe from
flowing back into the room.
[0038] The above mentioned description is only the exemplary
embodiment of the present invention, which cannot limit the present
invention. Within the spirit and principle of the present
invention, any modification of the equivalent structure, or direct
or indirect application in other related technical fields all shall
be included in the protection scope of the present invention.
