Description
FIELD OF THE INVENTION
[0001] The present invention relates to a water stopper structure,
and more particularly to a water stopper structure for a washing
sink which allows obtaining a double seal effect and a tight water
stop.
BACKGROUND OF THE INVENTION
[0002] A conventional washing sink in the kitchen is used to wash
vegetables or dishes, so the water sink includes a larger diameter
hole defined on a bottom end thereof to receive a water seat. The
water seat has a small diameter groove defined on a bottom end
thereof, and the small diameter groove has a first outlet and an
orifice defined on a bottom end thereof. The small diameter groove
has first outer threads formed around an outer rim thereof to screw
with a tube, and the water seat includes second outer threads
arranged around an outer rim thereof to screw with a forcing ring
so that the water seat is fixed in the larger diameter hole of the
washing sink.
[0003] To store water in the washing sink, a water stopper is fixed
in the small diameter groove of the water seat, and a filter cup is
fitted into the water seat to filter food debris and residues,
wherein the filter cup and the water stopper are connected
together, and a guide bolt is insert through the water stopper and
the filter cup so that the water stopper is connected with a bottom
end of the filter cup, and the water stopper is made of plastic
material and has a tilted face to match with a connecting surface
of the small diameter groove and the water seat so as to stop
water, and the filter cup is placed in the water seat to collect
the food debris and residues.
[0004] Because the tilted face of the water stopper matches with an
inner wall of the small diameter groove to stop water, so if the
inner wall of the small diameter groove is not worked precisely or
the tilted face of the water stopper can not match with the inner
wall of the small diameter groove tightly, water will leak from the
washing sink.
[0005] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages.
SUMMARY OF THE INVENTION
[0006] The primary object of the present invention is to provide a
water stopper structure for a washing sink which allows obtaining a
double seal effect and a tight water stop.
[0007] Another primary object of the present invention is to
provide a water stopper structure for a washing sink which prevents
water stored in the washing sink from leak.
[0008] To obtain the above objectives, a water stopper structure
for a washing sink provided by the present invention contains:
[0009] a washing sink having a large diameter hole defined on a
bottom end thereof to receive a water seat; [0010] the water seat
including a larger diameter cavity defined on an upper side thereof
and a small diameter cavity defined on a lower side thereof, the
small diameter cavity having a plurality of outlets defined on a
bottom end thereof and a guiding orifice defined on a central
position thereof, the larger diameter cavity of the water seat
including first outer threads formed around an outer rim thereof to
screw with a screwing ring so that the water seat is fixed in the
large diameter hole of the washing sink, and the small diameter
cavity of the water seat including second outer threads formed
around an outer rim thereof to screw with a tube; [0011] a filter
cup fitted into the larger diameter cavity of the water seat and
having a plurality of filtering apertures defined on a peripheral
wall of a lower side thereof and a central aperture formed on a
central position of a bottom end thereof to fit a guide bolt such
that a water stopper made of plastic martial is fixed; [0012] a
water stopper fixed under the filter cup and a diameter thereof
being equal to that of the small diameter cavity, the water stopper
including a sealing rib extending outward around an outer face of a
lower side thereof and a seal section extending outward from an
upper side of the outer face; [0013] the guide bolt including a
head segment and a guiding post such that the water stopper is
fixed between the head segment and the guiding post of the guide
bolt and under the filter cup.
[0014] The foregoing, as well as additional objects, features and
advantages of the invention will be more readily apparent from the
following detailed description, which proceeds with reference to
the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] FIG. 1 is a perspective view showing the assembly of a water
stopper structure for a washing sink according to a preferred
embodiment of the present invention. FIG. 2 is a perspective view
showing the exploded components of the water stopper structure for
the washing sink according to the preferred embodiment of the
present invention. FIG. 3 is a cross sectional view showing the
exploded components of the water stopper structure for the washing
sink according to the preferred embodiment of the present
invention. FIG. 4 is a cross sectional view showing the assembly of
the water stopper structure for the washing sink according to the
preferred embodiment of the present invention. Accordingly, as
shown in FIGS. 1-4, the water stopper structure comprises a washing
sink 10 having a large diameter hole 11 defined on a bottom end
thereof to receive a water seat 20. The water seat 20 includes a
larger diameter cavity 21 defined on an upper side thereof and a
small diameter cavity 22 defined on a lower side thereof, the small
diameter cavity 22 has a plurality of outlets 23 defined on a
bottom end thereof and a guiding orifice 24 defined on a central
position thereof. The guiding orifice 24 is circular, non-circular,
or geometric. The larger diameter cavity 21 of the water seat 20
includes first outer threads 25 formed around an outer rim thereof,
and the small diameter cavity 22 of the water seat 20 includes
second outer threads 26 formed around an outer rim thereof. The
first outer threads 25 of the larger diameter cavity 21 screw with
a screwing ring 27 to fix the water seat 20 in the large diameter
hole 11 of the washing sink 10. The second outer threads 26 of the
small diameter cavity 22 screw with a tube 28. In addition, A
filter cup 30 is fitted into the larger diameter cavity 21 of the
water seat 20 and has a plurality of filtering apertures 31 defined
on a peripheral wall of a lower side thereof and a central aperture
32 formed on a central position of a bottom end thereof to fit a
guide bolt 50 comprised of a head segment 51 and a guiding post 52
such that a water stopper 40 made of plastic martial is fixed
between the head segment 51 and the guiding post 52 of the guide
bolt 50 and under the filter cup 30, wherein a diameter of the
water stopper 40 is equal to that of the small diameter cavity 22,
and a shape of the guiding post 52 matches with that of the guiding
orifice 24 of the small diameter cavity 22. When the filter cup 30
is fitted into the larger diameter cavity 21 of the water seat 20,
the water stopper 40 is fixed in the small diameter cavity 22,
thereby assembling the water stopper structure.
[0020] To obtain a tight sealing effect, the water stopper 40
further includes a sealing rib 42 extending outward around an outer
face 41 of a lower side thereof, and the sealing rib 42 has a
flexible deformation rate and its outer diameter is equal to or
larger than a diameter of the small diameter cavity 22, the water
stopper 40 also includes a seal section 43 extending outward from
an upper side of the outer face 41, a diameter of the seal section
43 is larger that that of the small diameter cavity 22, and a
thickness of the seal section 43 is thin to obtain a deformable
rate. When the filter cup 30 and the water stopper 40 are fitted
into the water seat 20, the water stopper 40 is located in the
small diameter cavity 22, yet due to the diameter of the seal
section 43 is larger that that of the small diameter cavity 22, the
seal section 43 covers on a connection of the small diameter cavity
22 and the larger diameter cavity 21, and the filter cup 30 is
fixed in the larger diameter cavity 21 to collect food debris and
residues in the washing sink 10 in a washing process, and the
sealing rib 42 of the water stopper 40 contacts with an inner wall
of the small diameter cavity 22 tightly, the seal section 43 covers
the connection of the small diameter cavity 22 and the larger
diameter cavity 21 tightly by ways of a water pressure, thus
obtaining a double seal effect and a tight water stop.
[0021] While the preferred embodiments of the invention have been
set forth for the purpose of disclosure, modifications of the
disclosed embodiments of the invention as well as other embodiments
thereof may occur to those skilled in the art. Accordingly, the
appended claims are intended to cover all embodiments which do not
depart from the spirit and scope of the invention.
