BACKGROUND OF THE INVENTION
[0001] The present invention relates in general to a pressurized gas-water mixer, and more
particularly, to a pressurized gas-water mixer which is utilized in a multifunctional
oxygenated water machine in order to mix the water and the ozone quickly to form ozonated
water or hydrogen peroxide water.
[0002] Most drinking water machine utilize several pre-filters to remove the solid sediments
from the water, then use a reverse osmosis filter to further remove other impurities,
and finally use a post-filter to remove any strange odor from the water. Water that
has gone through this process becomes safe and potable and is referred to as pure
water. However, there is a problem that arises from this kind of filtering. This problem
arises because the filtering process skims out both dirty particles and organic materials.
The skimmed out organic material gradually accumulates with usage and facilitates
the growth of unwanted bacteria in the filters. In order to avoid the health effects
of the unwanted bacteria the consumer is forced to change the filters frequently.
If the consumer does not change the filters frequently the bacteria density in the
water produced will exceed the standard allowed for potable water.
[0003] Furthermore, even though the container is a closed space it is still highly probable
that the container will become a virtual nirvana for bacteria. The water delivery
outlet closest to the container is the most vulnerable to contamination by bacteria,
but this is by no means the only site of potential contamination. This is because
once the water delivery outlet closest to the container is contaminated, the bacteria
will likely migrate to the rear of the container. There is, therefore, a need to kill
the bacteria in the container.
[0004] In order to kill the bacteria in the container a gas-water mixer is installed in
a drinking water machine in order to mix the water and the ozone fast to form ozonated
water. A convention gas-water mixer is disclosed in U.S. Pat. No. 5,863,128. With
reference to Figure 1, the convention gas-water mixer comprises a hollow main body
la, a water inlet 11a and a water outlet 12a respectively defined in left and right
site of the main body 1a and a gas inlet 13 a defined in a bottom of the main body
1a. The gas inlet 13 a and the water inlet 11 a are formed perpendicularly in order
to let the water and the ozone respectively enter into the main body 1a to dissolve
each other and form ozonated water.
[0005] When the water and the ozone of the convention gas-water mixer 10a enter into the
main body 1a, however, any collision will not be produced between both of them in
relation to a distance and a mix area because of the water inlet 11a and the gas inlet
13a is formed perpendicularly. It is difficult to effectively dissolve the water and
the ozone to form ozonated water fast. Therefore, because of the longer period of
time required by the drinking water machine to form ozonated water, it could not produce
ozonated water quickly enough for the consumer; the time required by the conventional
ozonated water producer made its use inconvenient to consumers.
BRIEF SUMMARY OF THE INVENTION
[0006] The present invention provides a pressurized gas-water mixer which utilizes a pressure
different to dissolve the water and the ozone effectively and quickly so as to form
ozonated water or hydrogen peroxide water.
[0007] The pressurized gas-water mixer provided by the present invention includes a hollow
main body, an inlet cap with at least one water inlet and at least one gas inlet and
an outlet cap with at least one water outlet. An inside of the main body near the
water inlet and the water outlet respectively forms a flow guiding board in order
to let the water flow quickly and smooth and mix with the ozone quickly.
[0008] An end of the gas inlet inside of the main body provided by the present invention
extends to form an extending tube. An end of the extending tube has a taper protrusion
which has a through channel formed circularly from an outside of the taper protrusion,
and consequently, the ozone gas can directly flow from the through channel to the
hollow main body.
[0009] These and other objectives of the present invention will become obvious to those
of ordinary skill in the art after reading the following detailed description of preferred
embodiments.
[0010] It is to be understood that both the foregoing general description and the following
detailed description are exemplary, and are intended to provide further explanation
of the invention as claimed.

DETAILED DESCRIPTION OF THE INVENTION
[0012] Reference will now be made in detail to the preferred embodiments of the present
invention, examples of which are illustrated in the accompanying drawings. Wherever
possible, the same reference numbers are used in the drawings and the description
to refer to the same or like parts.
[0013] Referring to figures 2 and 3, a pressurized gas-water mixer 10 in accordance with
the present invention, which is utilized in a multifunctional oxygenated water machine,
comprises a hollow main body 1, an inlet cap 2 that comprises at least one water inlet
21 and at least one gas inlet 22 and an outlet cap 3 that comprises at least one water
outlet 31. The water inlet 21 and the gas inlet 22 are respectively mounted with a
water conveying pipeline and a gas conveying pipeline. The water and the ozone gas
enter through the water inlet 21 and the gas inlet 22 into the pressurized gas-water
mixer 10 to mix with each other so as to form ozonated water or hydrogen peroxide
water.
[0014] With further reference to Figures 3 to 5, the hollow main body 1 preferably is a
Venturis, and has an inlet 11 for entering the water and the ozone gas and an outlet
12 for flowing out a product. The hollow main body 1 near the inlet 11 is a narrow
portion 13 and diameters of the hollow main body 1 in direction to the outlet 12 are
broad by degrees. The inlet cap 2 is mounted with the hollow main body 1 near the
inlet 11 and they are preferably threaded with each other. The inlet cap 2 is preferably
a converse E shape and has two water inlets 21 formed respectively on an upper and
a lower portion of the inlet cap 2 and a gas inlet 22 formed in a center of the inlet
cap 2. The gas inlet 22 extends to form an extending tube 221 corresponding to the
narrow portion 13 of the hollow main body 1. An end of the extending tube 221 near
the narrow portion 13 has a taper protrusion 224 which has a through channel 223 formed
circularly from an outside of the taper protrusion 224. The ozone gas directly pass
through the through channel 223 and flow into the hollow main body 1, and then, the
water and the ozone gas come across in the narrow portion 13 so as to make the hollow
main body 1 produce a Venturis effect. Therefore, the water and the ozone gas have
a pressure difference at the across site in order to dissolve the water and the ozone
effectively and quickly so as to form ozonated water or hydrogen peroxide water.
[0015] Furthermore, the hollow main body 1 comprises a flow guiding board 111 formed in
an inner surface near the inlet 11 and the extending tube 221 also comprises a flow
guiding board 222 formed circularly from an outer surface of the extending tube 221
(see Figures 2 and 6). The flow guiding board 111 and 222 guides the water to flow
forward to the narrow portion 13 quickly.
[0016] Besides, the outlet cap 3 is mounted with the other end of the hollow main body 11
near the outlet 12 and they are preferably threaded with each other. The outlet cap
3 comprises two water outlets 31. In addition, the hollow main body 1 preferably circularly
forms a flow guiding board 14 at the inner surface near the outlet 12 (see Figures
2 and 7).
[0017] With reference to Figures 8 and 9, the water (it could be filtered water) and the
ozone gas are respectively come from the two water inlet 21 and the gas inlet 22 and
flow through into the hollow main body when the pressurized gas-water mixer 10 is
desired to produce ozonated water. When the water (see dotted line and black arrowhead
in the drawing) go through the flow guiding board 111 and 222 forward into the narrow
portion 13 of the hollow main body 1 and the gas (see dotted line and white arrowhead
in the drawing) go through the through channel 223 of the taper protrusion 224 forward
into the narrow portion 13 of the hollow main body 1, the water and the ozone gas
come across at the narrow portion 13 for producing a whirlpool, a rotation and a collision
between each other. Therefore, the water and the ozone gas are dissolved with each
other to form ozonated water in the hollow main body 1 (see real line and black arrowhead
in the drawing). The ozonated water is guiding by the flow guiding board 14 forward
to the outlet 3 through the water outlet 31 and storing in the pressurized gas-water
mixer 10.
[0018] Thereby, the pressurized gas-water mixer in accordance with the present invention
can let the water and the ozone gas parallel in a same direction through the water
inlet 21 and the gas inlet 22 into the hollow main body 1, and therefore, the hollow
main body 1 forms a Venturis. The Venturis effect of the hollow main body 1 is utilized
to form a pressure difference at the across site of the water and the ozone gas, and
then the ozone gas is attracted into the hollow main body 1 when the water flows out
so as to produce an attraction. Consequently, the water and the ozone gas can flow
quickly and smooth and mix with each other quickly.
