Two-Path Water Output Device
Abstract
A two-path water output device includes a valve, and is mounted
around by a shell. The valve has a first waterway and a second
waterway. The first waterway is constantly connected to a water
converter, while the second waterway is controlled to be open or
closed by a control valve core. Such two-path structure is simple,
novel and easily controllable for two types of water output like
tap water and filtered water. When the second waterway is closed,
the water pressure switches a water converter connected to the
inlet end of the valve to the first waterway to output water. When
the second waterway is open, the released pressure switches to the
first waterway to output water.

[0040] With reference to FIG. 1-4, a first embodiment of a two-path
water output device in accordance with the present invention
includes a valve 1, a shell 2, a first waterway A, and a second
waterway B.
[0041] The valve 1 is mounted around by the shell 2, has a first
inlet channel 31, a second inlet channel 32, a first trough 11, a
second trough 12, a first outlet channel 4, a second outlet channel
5, an outlet conduit 7, a water outlet panel 13, a switch valve
core 61, a first valve seat 81, a first spring 91, a control valve
core 62, a second valve seat 82 and a second spring 92. The first
inlet channel 31 and the second inlet channel 32 are juxtaposedly
and axially formed in an inlet end of the valve 1 or the second
inlet channel 32 is formed inside the first inlet channel 31. The
first trough 11 and the second trough 12 are juxtaposedly and
radially formed inside the valve 1.
[0042] The first outlet channel 4 and the second outlet channel 5
are axially and juxtaposedly formed inside an outlet end of the
valve 1.
[0043] The first outlet channel 4 includes a first inside outlet
channel 41 and a first outside outlet channel 42. The first trough
11 communicates with the first inlet channel 31 and the first
outlet channel 4. The second trough 12 communicates with the second
inlet channel 32 and the second outlet channel 5. The outlet
conduit 7 is mounted around the outlet end of the valve 1 and an
O-type collar seal is held between the outlet end of the valve 1
and the outlet conduit 7. The first inside outlet channel 41 and
the first outlet channel 42 are concentrically mounted inside the
outlet conduit 7. The first inside outlet channel 41 has a water
softener 10 mounted therein to soften the water in the first inside
outlet channel 41.
[0044] The water outlet panel 13 is mounted on an inner edge
portion of the first outside outlet channel 42, and has multiple
water holes formed through the water outlet panel 13 to spray
water.
[0045] The switch valve core 61 is mounted inside the first trough
11, and selectively controls one of the first inside outlet channel
41 and the first outside outlet channel 42 to communicate with the
first inlet channel 31. The first valve seat 81 is mounted in a top
inner portion of the first trough 11 to pair with the switch valve
core 61. The first spring 91 is mounted in a bottom inner portion
to restore the switch valve core 61 back to an original place
quickly.
[0046] The control valve core 62 is mounted in a top inner portion
of the second trough 12. The second spring 92 is mounted in a
bottom end of the second trough 12 to restore the control valve
core 62 back to an original place quickly.
[0047] To ensure a hermetic seal, O-type collar seals are mounted
between an inner surface of the valve 1 and each of the first valve
seat 81 and second valve seat 82, between the switch valve core 61
each of the first valve seat 81 and an inner surface of the valve
1, and between the control valve core 62 and each of an inner
surface of the valve 1 and the second valve seat 82.
[0048] A lever 14 is connected between a top portion of the switch
valve core 61 and a top portion of the control valve core 62. A
central portion of the lever 14 is pivotally mounted on an inner
wall of the valve 1. A first end of the lever 14 is inserted into a
switching slot on the top portion of the switch valve core 61. A
height of the switching slot of the switch valve core 61 is greater
than a width of the first end of the lever 14. A second end of the
lever 14 is securely mounted in a reduced neck in the top portion
of the control valve core 62. A start button 15 is mounted on a top
surface of the control valve core 62 and protrudes beyond the shell
2. A lower side of a first end of the switch button 16 is hinged
with the top portion of the switch valve core 61. A lower side of a
central portion of the switch button 16 is hinged with the inner
wall of the valve 1. A second end of the switch button 16 is
suspended to be pivotable with respect to the centrally hinged
point.
[0049] To ease connection between the two-path water output device
and a water converter, the valve 1 has an external thread 17 formed
on the inlet end thereof
[0050] With reference to FIG. 1-2, the first waterway A is
sequentially formed by the first inlet channel 31 through the first
trough 11 and the first outlet channel 4, and tap water flows
through the first waterway A. The second waterway B is sequentially
formed by the second inlet channel 32 through the second trough 12
and the second outlet channel 5, and filtered water flows through
the second waterway B. The first waterway A is controlled by an
external valve core and the second waterway B is controlled by the
control valve core 62. Alternatively, the first waterway A and the
second waterway B can be respectively controlled by the control
valve core 62 and the external valve core. What flow through the
first waterway A and the second waterway B include, but are not
limited to, tap water and filtered water respectively.
[0051] In the present embodiment, operation of the two-path water
output device is as follows. When the start button 15 is pressed,
the second waterway B forms a passage for filtered water to flow in
the second waterway B. At same time, tap water is closed through
the water converter connected to the inlet end of the valve 1. When
the first end of the switch button 16 is pressed, the start button
15 is popped up by the lever 14 and the second waterway B is
blocked such that no filtered water can flow in the second waterway
B. Meanwhile, tap water is opened through the water converter
connected with the valve 1 to flow in the first waterway A. Pushing
the switch button 16 again can change to sprinkle tap water.
[0052] With reference to FIG. 5, a second embodiment of a two-path
water output device in accordance with the present invention is
shown. The first inlet channel 31 and the second inlet channel 32
are axially formed in the inlet end of the valve 1, the first
outlet channel 4 and the second outlet channel 5 are axially formed
in the outlet end of the valve 1, a third trough 18 is radially
formed inside the valve 1.
[0053] The first waterway A is sequentially formed by the first
inlet channel 31 through the third trough 18 and the first outlet
channel 4. The second waterway B is sequentially formed by the
second inlet channel 32 through the third trough 18 and the second
outlet channel 5 The control valve core 62 is mounted inside the
third trough 18 to control the second waterway B to open or close,
and the first waterway A is kept in connection with and is
controlled by the water converter to open or close. As being
similar to the foregoing embodiment, operation of the present
embodiment is not repeated here.
[0054] With reference to FIG. 6, a third embodiment of a two-path
water output device in accordance with the present invention is
shown. The first inlet channel 31 and the second inlet channel 32
are axially formed in the inlet end of the valve 1, the first
outlet channel 4 and the second outlet channel 5 are axially formed
in the outlet end of the valve 1, a third trough 18 is radially
formed inside the valve 1.
[0055] The first waterway A is sequentially formed by the first
inlet channel 31 through the third trough 18 and the first outlet
channel 4. The second waterway B is sequentially formed by the
second inlet channel 32 through the third trough 18 and the second
outlet channel 5. The control valve core 62 is mount inside the
third trough 18 to control the second waterway to open or close,
and the first waterway A is kept in connection with and is
controlled by the water converter to open or close. As being
