Description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] The present invention is related to a spray head kitchen
faucet, and more particularly, to one provided with an extension
for the spray head to be separately pulled out for use to
facilitate washing to clean the kitchen sink set or the
kitchen.
[0003] (b) Description of the Prior Art
[0004] Single handle kitchen faucet generally available in the
market is usually used in modern kitchen, particularly in
well-developed countries including Japan, USA and those in Europe.
However, its spout delivers only one mode of water as that from an
ordinary stem faucet and fails to deliver the water jet effectively
to clean the kitchen or areas other than the sink, thus to
significantly offset the efficacy of the kitchen faucet.
SUMMARY OF THE INVENTION
[0005] The primary purpose of the present invention is to provide a
kitchen faucet with a spray head for the kitchen faucet to be more
practical in the kitchen. To achieve the purpose, a guide and a
diverter adapted with a cartridge are provided to control the tap
water entering into the faucet to be delivered out of the spout
either in jet or in sprinkle mode depending on the pressure applied
to the handle.
[0006] The foregoing object and summary provide only a brief
introduction to the present invention. To fully appreciate these
and other objects of the present invention as well as the invention
itself, all of which will become apparent to those skilled in the
art, the following detailed description of the invention and the
claims should be read in conjunction with the accompanying
drawings. Throughout the specification and drawings identical
reference numerals refer to identical or similar parts.
[0007] Many other advantages and features of the present invention
will become manifest to those versed in the art upon making
reference to the detailed description and the accompanying sheets
of drawings in which a preferred structural embodiment
incorporating the principles of the present invention is shown by
way of illustrative example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] The following descriptions are of exemplary embodiments
only, and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0014] Referring to FIGS. 1, 2, and 3, a preferred embodiment of
the present invention for a kitchen faucet provided with a spray
head is essentially comprised of a body 10 including a base holder
11, an adapter 12, an inner tube 13, an inner cylinder 20, a
cartridge 30, a guide 40, a diverter 50, a retaining ring 60, a
wave generator 70, a spout 80 and a control handle 90. The inner
tube 13 containing a supply pipe 133 is inserted into the base
holder 11. The supply pipe 133 relates to a reduced pipe having
wider bottom and smaller top. The top of the supply pipe 133 is
provided with an externally threaded coupling 132 to be locked into
the adapter 12, and the bottom in larger diameter is provided with
an internally threaded coupling 121 to be pivoted to an extension
hose (not illustrated). The adapter 12 has a hollow 121 provided
inside, a threaded coupling hole 122 at the bottom, a larger
opening internally threaded at the front, and a through hole 123 at
the rear to be connected to the control handle 90. The inner
cylinder 20 contains a three-gradation hollow 201, an axial hole
203 at the rear for the cartridge 30 to pass through, and a through
hole 202 at bottom and closer to the rear for receiving the
insertion by the inner tube. A cylinder cover 21 having an axial
211 is first connected to the rear of the inner cylinder 20 and the
inner cylinder is then placed into the hollow 121 of the adapter
12. A double flange 301 sandwiching a resilient washer 33 is
provided at where closer to the front cartridge 30 to be inserted
through an axial hole 411 in the guide 40 and a through hole 531 in
the diverter 50; and the rear of the cartridge 30 is threaded and
inserted with a coil 31 before passing through the inner cylinder
20, the adapter 12 and locked to a connection sleeve 22, which in
turn is connected to a pivot 91 of the control handle 90 by means
of a pin. A pair of C rings 32 is used to retain the center of the
cartridge 30 in the axial hole 411 of the guide 40. The guide 40 is
provided with an opening 42 at its front to be coupled to a
protrusion 53 from the end of the diverter 50, and a protrusion 41
containing an axial hole 411 and a guide hole 412 at its rear. The
guide 40 is coupled to the diverter 50 and rests on the second
gradation in the inner cylinder 20 while the second half of the
diverter rests in the opening of the guide 40. The diverter 50 has
a hollow 51, a threaded opening in front to be locked to the
retainer ring 60, a protrusion 53 in the rear to be inserted into
the hollow 42 of the guide 40, and an outer gasket 52 at the
protrusion 53 provided on its end surface multiple guide holes 521
penetrating through the outer gasket 52. The retainer ring 60 has
an opening at front, a through hole 601 in a diameter slightly
smaller than that of the washer 33, and the outer circumference
being threaded to be locked to the hollow 51 in the diverter 50. An
externally threaded coupling 81 is provided to the rear of the
spout 80 for the spout 80 to be locked into the opening of the
adapter 12, and a hollow 811 with an opening in the spout 80 is
provided to accommodate the diverter 50, and a main hole 801 in
smaller diameter is provided at the front of the spout 80 to
accommodate a wave generator 70 comprised of a first dispersion
member 71, a washer 72 and a strainer 73, and a second dispersion
member 74. Wherein, the first dispersion member is provided with a
central hole and a side groove, and the second dispersion member is
also provided with a side groove. Multiple minute pores 802
penetrating through the hollow 811 are provided on the outer
circumference of the main hole 801.
[0015] As illustrated in FIGS. 4 and 5, a proper force is applied
onto the control handle 90 to press it down for a certain extent
before tuning it to pull back the connection sleeve 22 pivoted to
the control handle 90 and in turn, to pull back the cartridge 30.
Both of the guide 40 and the washer 33 move backward to permit the
through hole 601 of the retainer ring 60 to open. Meanwhile, water
entering from the inner tube of the body 10 flows through the guide
hole 412 of the guide 40, then diverted by the through hole 531 of
the diverter, then the through hole 601 of the retainer ring 60 and
the wave generator 70 to be forced to increase the flow velocity
and form a powerful jet upon leaving the main hole 801 of the spout
80. As illustrated in FIG. 5, when an even greater force is applied
to press and rotate all way down the control handle 90, the
cartridge 30 is given its maximal displacement at the same time to
move the guide 40 back until it is cleared away from the protrusion
53 of the diverter 50. In turn, the hollow 42 of the guide 40 is
connected through the guide hole 521 of the diverter 50, and the
retreating washer 33 closes up the through hole 513 of the diverter
50. Therefore, the water entering from the inner tube 13 flows
through the guide hole 412 of the guide to the spout 80 through the
guide hole 521 of the guide 50 to sprinkle the water from those
multiple minute pores 802 of the spout 80. When the control handle
90 is released, the cartridge 41 for being subject to the coil 31
returns to its place in the configuration as illustrated in FIG. 3,
and stops the delivery of water since both of the through hole 601
of the retaining ring 60 and the guide hole 521 of the diverter 50
are closed up.
[0016] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0017] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
