module inside. The moving module has a central hole, in addition,
has an upper float-ball and a lower float-ball at inner space to
match the upper slot and the lower slot which both are set up on
the draining part. Furthermore, an outer convex ring set on a
rubber module is fixed into the draining hole on the bottom of the
cistern, and an outer convex ring on the cylinder at the lower
portion of the draining part is inserted into the hole of the
rubber module, meanwhile the latch of the cylinder is hooked onto
the bottom of the rubber module to make the water drainer be fixed.
With the structural improvement, a purpose of two-stage water

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention provides a structural improvement of a
water drainer of a cistern, especially in one-piece toilet. The
water drainer has an upper float-ball and a lower float-ball which
both can adjust the output of water according to the user's demand.
In addition, the outer convex ring of the rubber module is fixed
into the draining hole on the bottom of the cistern, and the outer
convex ring of the cylinder at lower portion of the draining part
is inserted into the hole of the rubber module, meanwhile the latch
of the cylinder is hooked onto the bottom of the rubber module to
make the water drainer be fixed.
[0003] 2. Background Art
[0004] It is well known that to assemble the water drainer of the
commonly used one-piece toilet, one must move the hook of the water
drainer to both side of cistern, then fix the water drainer in the
cistern by screws. The operation is not easy because the space of
cistern is too small to finish locking the screws, and may spend
much time. Thus it may cause the difficulty of the installers, also
increase extra cost of parts.
BRIEF SUMMARY OF THE INVENTION
[0005] The present invention of the structural improvement of a
water drainer in a cistern intends to solve the technological
problem mentioned above. According to the present invention, the
outer convex ring of the rubber module is fixed into the draining
hole on the bottom of the cistern, and then the outer convex ring
of the cylinder at lower portion of the draining part is inserted
into the hole of the rubber module, meanwhile the latch on the
cylinder is hooked onto the bottom of the rubber module to make the
water drainer be fixed. This assembly method is not only simple and
fast, but also available for any type of cistern of toilet. The
present invention may provide users a more convenient operation,
also may save working hours and parts cost.
[0006] In view of this, the inventor of the present invention has
developed a structural improvement of a water drainer in a toilet.
The water drainer has a draining part which has a moving module
inside. The moving module has a central hole, in addition, has an
upper float-ball and a lower float-ball at inner space, and has a
flush valve at lower portion. The draining part has an upper slot
and a lower slot, moreover at the lower portion has a cylinder
which is outside tapered. The cylinder has at least one or more
than one of outer convex ring and latch on the surface. There is
set up a rubber module at outside of the cylinder of the draining
part. The rubber module has flanges separately at top and bottom,
and has an outer convex ring at middle. The hole of rubber module
is hollow shaped with internal taper.
[0007] The present invention of the structural improvement of a
water drainer in a cistern of a toilet provides an uncomplicated
configuration of lower float-ball and upper float-ball for the
object of controlling water draining, and achieves the effect of
water-saving.

DETAILED DESCRIPTION OF THE INVENTION
[0010] In order to explain the technique of the present invention
clearly and completely, the present invention will now be described
in reference to the drawings, like numerals referring to like parts
throughout the drawings.
[0011] Please referring now to FIG. 1 to FIG. 2, there is
illustrating a structural improvement of a water drainer of a
cistern according to the present invention.
[0012] The water drainer comprises:
a moving module(66) which has a central hole(72), and has a flash
valve(62) at bottom, and has upper float-ball(60) and lower
float-ball(63) inside; at one end of the upper float-ball(60) and
the lower float-ball(63) has a plate(65) separately; each plate has
an engaging surface(68) on it; a draining part (59) has an upper
slot (61) and a lower slot (64); at the lower portion has a
cylinder which is outside tapered; the cylinder has at least one or
more than one of outer convex ring(67) and latch(77) on the
surface; a base(69)is set up on the cylinder; the base(69) and the
inner space of the cylinder are outlet hole(71); the outlet
hole(71) has a flange(70) on it; the flange(70)is conjugated with a
flash valve(62); a rubber module(75) which is set at outside of the
cylinder of the draining part(59) has a flange(78) separately at
top and bottom, and has an outer convex ring(76) at middle; the
hole of the rubber module is hollow shaped with internal taper. a
moving module(66) is installed inside of the draining part(59) of
the water drainer, the outer convex ring(76) of the rubber
module(75) is conjugated and fixed into the draining hole on the
bottom of the cistern; next, the outer convex ring of the cylinder
which is at lower portion of the draining part(59) is clicked into
the hole of the rubber module(75); meanwhile the latch(77) of the
cylinder is hooked with the bottom of the rubber module(75) to make
the water drainer be fixed. As described above the structural
improvement of a water drainer according to the present invention
is accomplished.
[0013] When the first-stage switch-bar (not shown in figures) is
pressed, the flush valve(62) is pulled upwards a distance to make
the engaging-surface(68) of the upper float ball(60) of the water
drainer fasten with the upper slot(61) of the draining part (59).
Thus the water is discharged to the toilet from the outlet hole
(71) until the water level is dropped down under the upper float
ball(60) of the water drainer; the engaging-surface(68) of the
upper float ball(60) is detached with the upper slot(61) of the
draining part(59), then the flush valve(62) moves downward to cover
the outlet hole(71).
[0014] When the second-stage switch-bar (not shown in figures) is
pressed, the flush valve(62) is pulled upwards a longer distance to
make the engaging-surface(68) of the lower float ball(63) of the
water drainer fasten with the lower slot(64) of the draining
part(59). Thus the water is discharged to the toilet from the
outlet hole(71) until the water level is dropped down under the
lower float ball(63) of the water drainer; the engaging-surface(68)
of the lower float ball (63) is detached with the lower slot(64) of
the draining part(59). Until the water is discharged completely to
the toilet, the flush valve(62) moves downward to cover the outlet
hole(71).
[0015] The present invention of the structural improvement of a
water drainer of a cistern is performed by the uncomplicated
configuration of upper and lower float-balls(60)(63). The
installation is easy and the operation is convenient, therefore the
present invention would be able to provide two-stage water outflow
according to user's demands and achieve the object of
water-saving.
[0016] Having illustrated and described the principles of my
invention by what are presently preferred embodiments, it should be
apparent to those persons skilled in the art that the illustrated
embodiment may be modified without departing from such principles.
It will be understood that there is no intent to limit the
invention by its disclosure, but rather it is intended to cover all
modifications and alternate constructions falling within the spirit
and the scope of the invention as defined in the appended
claims.
