FAUCETS PROVIDING MIXED WATER AND AIR FLOW
FIELD OF THE INVENTION
The present invention relates to faucets providing mixed water and air flow,
including
faucets having a faucet head with a sliding member to control a water valve
enabling the mixing
of water and air.
DESCRIPTION OF THE PRIOR ART
Control valves for faucets have various components, many of which are discrete
parts
that are assembled to ensure good water-tight seal and long-term durability or
reliability. The
manufacturing of faucets, however, can become complicated and expensive as the
features,
controls, and/or functions of faucets are revised over time.
For certain water faucet applications, one-touch valves were developed so a
tap on an
actuation element can control the water flow. An example of one-touch valves
is those supplied
by the 3M Company for mounting externally to a faucet. A one-touch valve may
simplify the
operation of a faucet. However, these one-touch valves are add-on components
for placements at
where water is discharged, i.e., directly at the outlet of a faucet. This also
means that the valves
are operated directly at the outlet where water flows through.
But adding a one-touch valve changes the overall design, dimension, and
aesthetic
appearance of a faucet, limiting the flexibility and/or attractiveness of the
design or application.
A post-sale-modification may raise reliability, durability, or repair issues.
Further, operating a
faucet outlet with hands, arms, or other parts of one's body, which may have
grease, bacteria, or
other contaminants may add grease, bacteria, or other contaminants to the
faucet outlet itself,
leading to hygiene or other concerns.
CA 2990926 2018-01-05
Conventional faucets contain handles to control water flow. When the faucet is
operated
in circumstances that require frequent onfoff operations, having handles that
are away from the
location where water is discharged may cause inconvenience. Although placing a
handle near the
location where water is discharged may be a solution, it may limit design
options. For example,
if a faucet has a removable head that travels with a connecting hose, the
location of the control
may affect the faucet hose or faucet design or limit its portability. As
another example, closing
the distance between the location where water is discharged and the control
handle may limit
design aesthetics.

inlets 302 of water valve 30 to enable the water vale's mixing of water and
air. For example, an
9
CA 2990926 2018-01-05
opening on faucet head 1 (or outer case 10) in communication with chamber 11
can serve as the
air inlet of chamber 11 to supply air to water valve 30. An opening 13 of
outer casing 10, as
shown in FIG 3 and will be described further below, can be adapted to
communicate with and
allow air intake to air inlets 302 of water valve 30. A side opening of faucet
head 1 for
accommodating a switch valve 70, as shown in FIG. 3 and will be described
further below, can
also be adapted to communicate with and allow air intake to air inlets 302 of
water valve 30.
Alternatively or additionally, a center outlet 81 and/or a plurality of
peripheral outlets
82, as shown in FIG. 3, can serve as an air inlet of chamber 11 to supply air
to water valve 30. As
will be described further below, center outlet 81 and peripheral outlets 82
can be adapted to
communicate with chamber 11 to discharge a flow of the water-and-air mixture
in a stream
discharge mode and a spray discharge mode, respectively. When in the stream
discharge mode,
one or more peripheral outlets 82 can be adapted to communicate with and allow
air intake to air
inlets 302 of water valve 30. When in the spray discharge mode, center outlet
81 can be adapted
to communicate with and allow air intake to air inlets 302 of water valve 30.
Water valve 30 can include a control valve 301 movable within water valve 30
between
a first position and a second position. The first position can be a position
that enables mixing air
from air inlets 302 with water from water inlet 305 to provide a mixture of
water-and-air flow.
The second position can be a position that enables shut-off of a mixture of
water-and-air flow. A
direction of the movement of control valve 301 between the first position and
the second position
can be substantially parallel to a direction of a water flow (or a water-and-
air flow) from first end
I 1 1 to second end 112 of chamber 11. Control valve 301 can be adapted to use
a water pressure
supplied by water hose 2 to facilitate an operation of control valve 301,
either in one direction or
in both directions.
Water valve 30 can be a water-pressure-assisted aerator with a control valve.
In one
CA 2990926 2018-01-05
embodiment and referring to FIG. 12, water valve 30 can contain a screen 303
coupled with
control valve 301 and located downstream of control valve 301. Screen 303 can
include a
plurality of water passageways 304, with as little as two or four passageways
to as many as a
dozen or dozens of passageways. Water passageways 304 can be in communication
with one or
more air inlets 302 of water valve 30 to enable the water valve's mixing of
water and air into a
mixture of water-and-air flow. Air inlets 302 may have openings from the side,
from the above,
from the lower portion of water valve 30, or having the openings in any of the
combinations. The
air inlets may enable the faucet head and the chamber to be designed with
flexibilities and with
openings or gaps to enable air flow,
Referring to FIGS. 3-5 and 12, control valve 301 can include a driving member
31 that
protrudes out from one end of water valve 30, such as from a lower portion or
the bottom of
water valve 30. Driving member 31 can be engaged with and driven by sliding
member 40 to
control a position of control valve 301. For example, driving member 31 can be
driven to move
control valve 301, such as moving it up, to turn on water valve 30 so that
water flows into at least
one first orifice 21 of cylinder 20 from water conduit 2b of water hose 2 and
into water inlet 305
of water valve 30. When control valve 301 is pushed up, it breaks the water-
tight seal between
control valve 301 and a lateral or internal wall of water valve 30 to cause
the water from the
connected water hose 2, through water conduit 2b, to flow through water inlet
305. Water inlet
305 may be equipped with a screen, a mesh, or some other debris- or particle-
blocking design to
avoid any debris or particle from entering the water-tight seal of control
valve 301, which may
cause it to lead or malfunction. When control valve 301 is lowered, it returns
to its water-tight
seal state, and the control valve 301 may be designed with surface(s) onto
which water pressure
may exert additional force to reinforce the water-tight seal between control
valve 301 and an
internal wall of water valve 30. The seal between control valve 301 and water
valve 30 may be
11
CA 2990926 2018-01-05
formed with rubber, resin, or other suitable sealing materials.
In one embodiment, the control valve may be coupled or equipped with a spring
and a
cam that moves or locks control valve in two or more different positions each
time the driving
member 31 is pressed. The design or operation may be similar to or a variation
of those used in
retractable/clicking pens. U.S. Patent No. 3,819,282 discloses one example of
such design. In
one embodiment of control valve 301, a second/resting position can provide a
water-tight seal
and stop water flow. A first position can open the seal between control valve
301 and internal
wall(s) of water 30, and the opening enables the water flow. A third position
or additional
positions are optional, and when used, it/they may keep the seal open, but
modulate the water
flow by providing a bigger (or smaller) gap(s) to provide more (or less) water
flow than the
water flow at the first position.
Driving member 31 can include a pin, rod, stern, tube, or an elongated
structure
protruding out of water valve 30. Driving member 31 can include a head for
coupling with
sliding member 40 and a body connected to the head for transmitting force
and/or motion.
With reference to FIGS. 3-5, faucet head 1 can include a pin 50 extending out
of a
cavity 25 from a through hole 26 to engage with sliding member 40 so that
sliding member 40
can actuate driving member 31 via pin 50.
As illustrated in FIGS. 3, 8, 9, 10, and 11, sliding member 40 can be movably
coupled
with faucet head 1 at or near a side of faucet head 1 (or outer casing 10), to
enable an operation
of control valve 301 within water valve 30. The operation may occur by sliding
sliding member
40 in a direction substantially parallel to, but opposite to, for example, the
direction of a water
flow from first end 111 of chamber 11 to second end 112 of chamber 11. The
sliding of sliding
member 40 causes control valve 301 to move between the first position and the
second position.
For example, a movement of sliding member 40 can be in a direction
substantially parallel to a
12
CA 2990926 2018-01-05
direction of the water flow from first end 111 of chamber 11 to second end 112
of chamber 11.
Sliding member 40 can include a first surface 411 and a second surface 422,
which is
mechanically coupled with first surface 411. First surface 411 can be adapted
for user operation,
such as to slide sliding member 40 in a direction substantially aligned with a
side surface of
faucet head 1, such as a side surface of outer casing 40. Second surface 422
can be adapted to
engage with control valve 301 to move control valve 301 from the second
position to the first
position when first surface 411 is slid in a direction substantially opposite
to the direction of a
water flow from first end 111 of chamber 11 to second end 112 of chamber 11.
Second surface
422 can be adapted to engage with control valve 301 to restore control valve
301 from the first
.. position to the second position when first surface 411 is slid again in the
direction substantially
opposite to the direction of the water flow from first end 111 of chamber 11
to second end 112 of
chamber 11.
For example, sliding member 40 can include a sliding portion 41 including
first surface
411 and a lever 42 including second surface 422. Lever 42 can be coupled to
and extending from
sliding portion 41. First surface 411 can be configured to be substantially
perpendicular to
second surface 422. A part of lever 42 can be limited in second orifice 22 of
cylinder 20. First
surface 411 can be an external face of sliding member 40. Sliding member can
include an
internal face 412 coupled with lever 42. First surface 411 can be adapted to
allow user operation
such as by sliding. First surface 411 can include a contact area, which may
have a curved profile,
a dimple, or some other surface shape, texture, or pattern so a user can
identify it by touching or
without looking. Internal face 412 can have a connection portion 414 slidably
connected with
outer casing 10. Sliding member 40 can be slidably coupled with a side of
faucet head 1 to cause
a substantially-upward movement of second surface 422 when first surface 411
is operated in a
substantially-upward direction. The substantially-upward movement of second
surface 422
13
CA 2990926 2018-01-05
causes control valve 301 to move from the second position to the first
position in a
substantially-upward direction. For example, second surface 422 can be caused
to contact/push
(or exert a force on) driving member 31 or pin 50 to cause driving member 31
to move control
valve 301 to the first or second position.
Sliding member 40 can include a button, a plate, a panel, a switch, a knob, a
toggle, a
stud, a key, or any structure having a surface adapted to enable user
operation, such as slide, push,
or other movement. Second surface 422 can be adapted to engage with control
valve 301. First
surface 411 and second surface 422 can be provided through a uni-body
construction or a
multiple-part construction.
As discussed above, control valve 301 can be configured to remain in the first
position
after sliding member 40 is slid and released. For example, sliding member 40
can be released
after being slid to cause control valve 301 to move to and remain in the first
position until sliding
member 40 is operated again, such as by sliding, to cause control valve 301 to
move from the
first position to the second position.
Sliding member 40 can also include a spring to return sliding member 40 to an
initial
position when sliding member 40 is not being operated. The spring may be part
of water valve
30 to provide the spring force to return sliding member 40 to its initial
position after a user
operate or releases it. The spring may also be a spring separated from a
spring of water valve 30
and be placed between sliding member 40 and one part of chamber 11.
Referring to FIGS. 3-7, chamber 11 can include, in cylinder 20, for example, a
cavity 24
located in inlet segment 201, cavity 25 formed at a bottom of cavity 24, and
through hole 26 in
spatial communication with cavity 25. At least one first orifice 21 can
communicate with cavity
24 and the outlet segment 202. Water valve 30 can be housed in cavity 24, and
driving member
31 can be accommodated in cavity 25.
14
CA 2990926 2018-01-05
Outer casing 10 can include a wall 12 configured to define chamber 11. Outer
casing 10
can include an opening 13 defined in wall 12 corresponding to sliding member
40 so that sliding
member 40 can be slid in opening 13 when first surface 411 is operated, as
shown in FIGS. 3, 10,
and 11. Preferably, a size of opening 13 is larger than that of sliding
portion 41 of sliding
.. member 40 so that sliding portion 41 can be accommodated in opening 13
while exposing first
surface 411. Opening 13 can include a recess 131 to accommodate, in whole or
in part, sliding
member 40 such that sliding member 40 can be operated in recess 131.
Referring to FIG 8, connection portion 414 can include two hooks 415 extending
from
internal face 412 of sliding member 40. Hooks 415 can be spaced part on
internal face 412. As
shown in FIGS. 3, 5, and 9-11, hooks 415 can be adapted to engage with wall 12
of outer casing
10 through an opening 14 of outer casing 10. Hooks 415 can engage with, such
as by contacting,
one or more edges defining opening 14. Hooks 415 can include one or more barbs
416 for
engaging with, such as by contacting, an inner surface 122 of outer casing 10.
Hooks 415 can be
resilient for insertion of connection portion 414 into opening 14 and adapted
to prevent
dislocation of sliding member 40 from outer casing 10 while allowing operation
of sliding
member 40.
Opening 14 can be adapted to limit a movement of sliding member 40 by
restricting the
movement of hooks 415. Opening 14 can be adapted to have a sufficient size
allowing sliding
movement of hooks 415 in a direction substantially parallel to the direction
of the water flow
from first end 111 of chamber 11 to second end 112 of chamber 11. For example,
a movement of
hooks 415 can be in a direction substantially parallel to a direction of the
water flow from first
end 111 of chamber 11 to second end 112 of chamber 11. Opening 14 can be
nested in opening
13 such that opening 13 allows for movement of sliding portion 41 in opening
13 caused by
movement of hooks 415 in opening 14.
CA 2990926 2018-01-05
In another embodiment, sliding member 40 can include an opening with edges for
engaging with hooks of a connection portion disposed at a side of faucet head
1. As discussed
above with respect to opening 14 and hooks 415 of connection portion 414, the
opening of
sliding member 40 and the hooks of the connection portion disposed at the side
of faucet head 1
can be similarly configured to engage with each other to enable sliding of
sliding member 40 in a
direction substantially parallel with the water flow from first end 111 of
chamber 11 to second
end 112 of chamber 11.
Referring to FIGS. 3-5 and 11, pin 50 can include a head 51 for sliding upward
and
downward in cavity 25 and a body 52 extending from head 51 and extending out
of through hole
26 from head 51. Head 51 can be configured to contact with and drive driving
member 31 of
water valve 30. A distal end of the body 52 can be in contact with and driven
by lever 42 of
sliding member 40.
Referring to FIGS. 3-5 and 11, faucet head 1 can further include a compression
spring
60 in cavity 25. Compression spring 60 can be accommodated between water valve
30 and head
51 of pin 50 to push pin 50 and sliding member 40 back to their previous
positions after sliding
member 40 is released.
An extension of through hole 22 of cylinder 20 can be defined by two opposing
limiters
221 formed proximate to through hole 22 so that movement of lever 42 of
sliding member 40 can
be limited between two limiters 221 after sliding member 40 is pressed or
released.
As shown in FIG. 3, when sliding member 40 is not operated, sliding portion 41
can be
positioned towards a lower end of opening 13 so that it can be slid upward.
When sliding
member 40 is slid upward, lever 42 can be moved substantially upward away from
the lower
limiter 221 to push pin 50 upwardly, as shown in FIG 11. Thus, driving member
31 of water
valve 30 can be driven to turn on water valve 30.
16
CA 2990926 2018-01-05
Whether sliding member 40 is operated or released can be shown using an on-off
indicator. For example, the indicator can indicate an "on" status by showing a
color, such as
green, of a surface exposed near a lower end of recess 131 when sliding member
40 is slid
upward in opening 13 and an "off' status by showing a different color, such as
red, of a surface
exposed near an upper end of recess 131 when sliding member 40 is not operated
or is released
after operation. Alternatively or additionally, the indicator can indicate the
"on" and/or "off"
status using symbols, illumination, or other means. Moreover, the indicator
can be adapted on
sliding member 40, such as on first surface 411.
Body 52 of pin 50 has can include a first seal washer 501 fitted thereon and
sealing
cavity 25 so as to prevent water leakage via through hole 26 from cavity 25,
as illustrated in
FIGS. 3 and 4.
Chamber 11 can provide a housing near second end 112 of chamber 11 to enclose
a
switch valve 70 guiding a flow of the water-and-air mixture between a stream
discharge and a
spray discharge. Switch valve 70 can be operated via a switch movably mounted
on a side
opening of faucet head 1.
For example, faucet head 1 can include switch valve 70 near second end 112 of
chamber
11 to switch a flow of the water-and-air mixture between a stream discharge
and a spray
discharge. For example, switch valve 70 can be arranged on cylinder 20 and
configured to switch
a water flow between a stream discharge mode and a spray discharge mode.
Faucet head 1 can
include a water outlet 80, as shown in FIGS. 3 and 4. Switch valve 70 can be
operated, such as
by pressing, to cause the water to be guided through a center outlet 81 or a
plurality of peripheral
outlets 82 of water outlet 80 from the at least one first orifice 21 to
produce at least two water
discharge modes, such as a stream discharge mode and a spray discharge mode.
With reference to FIGS. 6 and 7, cylinder 20 can include a cavity 27
communicating
17
CA 2990926 2018-01-05
with the at least one first orifice 21 to accommodate switch valve 70.
Cylinder 20 can further
include a recess 28 for accommodating water outlet 80. Recess 28 can include a
central channel
281 and a peripheral channel 282 communicating with cavity 27.
Second end 112 of chamber 11 can provide a stream discharge of a water-and-air
mixture through center outlet 81 of water outlet 80 and a spray discharge of a
mixture of water
and air through the plurality of peripheral outlets 82 of water outlet 80.
Center outlet 81 can be in
communication with and discharge water from central channel 281. The plurality
of peripheral
outlets 82 can be in communication with and discharge water from peripheral
channel 282.
Center outlet 81 can include a foam generator 811 to produce foamy water.
Cylinder 20 can be adapted to match with a water outlet so as to discharge
water from
the at least one first orifice 21 in a particular discharge mode.
Referring to FIGS. 3-5, faucet head 1 can further include an inflow connector
91
engaged at a top of cavity 24. Inflow connector 91 can include a threaded
portion 911 extending
from outer casing 10, a nut 92 engaging with threaded portion 911 of inflow
connector 91 and
locking inflow connector 91 and cylinder 20 to the top of outer casing 10, a
padding 93 located
between inflow connector 91 and a top of water valve 30 to limit water valve
30 in cavity 24, and
a second seal washer 94 fitted on padding 93 and contacting with cavity 24.
When control valve 301 of water valve 30 is configured to operate
automatically,
driving member 31 can be driven to move control valve 301 to a position
enabling water
discharge. Thereafter, control valve 301 can move back to an original position
to stop
discharging water.
When control valve 301 is not configured to be automatic, sliding member 40
can be
manually operated by the user to close control valve 301. Sliding member 40
can be operated to
drive driving member 31 of water valve 30 to move control valve 301 to a
position enabling
18
CA 2990926 2018-01-05
shut-off of water.
Thus, water valve 30 can be driven by sliding member 40 so as to avoid
touching and
contaminating water valve 30. Sliding member 40 can be rotatably connected
with cylinder 20 to
simplify faucet head 1 and reduce fabrication cost.
Water valve 30 can be a pre-assembled assembly with a control valve, such as
control
valve 301, inside the water valve and with a driving member, such as driving
member 31,
protruding through one end of the water valve and coupled with the control
valve to cause the
control valve to move between a first and a second position, such as between
the first and second
position described above.
Faucet head 1 can be further adapted to discharge water in different discharge
modes
using means other than switch valve 70.
While the preferred embodiments of the invention have been set forth for the

well as other
embodiments thereof may occur to those skilled in the art. The scope of the
claims should not be
limited by the preferred embodiments set forth in the examples, but should be
