Description

BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to drinking water, and more particularly to a method of supplying oxygenated water.

2. Description of Related Art

Oxygenated water is made by dissolving pure oxygen in water. The oxygenated water with 60 ppm oxygen has fine white bubbles within, and the oxygenated water with 100 ppm or more oxygen turns its color to milk white. People drink oxygenated water for absorbing the oxygen in the water to activate body cells. However, the oxygen tends to escape from the water easily, therefore people has to drink it up before it turning back into transparent.

It is convenient for consumers to buy bottled oxygenated water in a store. However, oxygen will escape from the water every time when the bottle is opened. It causes the dissolution ratio of oxygen in the remained water reduces if one doesn't drink the whole bottle once. Therefore, how to keep a constant dissolution ratio of oxygen in the oxygenated water every time when one wants to drink is an important issue.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a system of making oxygenated water of the preferred embodiment of the present invention, which includes a water tank 10, a pump 20, an oxygen supplier, which is an oxygen cylinder 30 in the present embodiment, and a controller 40.

The water tank 10 has a water inlet 12, a water outlet 14, a gas inlet 16, and a gas outlet 18. The water inlet 12 is on a sidewall of the water tank 10, and is adjacent to a top thereof. The water outlet 14 is on the sidewall of the water tank 10, and is adjacent to a bottom thereof. The high oxygenated water comes out of the water tank 10 through the water outlet 14. The gas inlet 16 is on the bottom of the water tank 10. An oxygen supplier is connected to the gas inlet 16. In the present embodiment, the oxygen supplier is an oxygen cylinder 30. Pure oxygen of the oxygen cylinder 30 enters the water tank 10 through the gas inlet 16 and is dissolved in the water. It may obtain oxygenated water with higher concentration of dissolved oxygen while the pure oxygen from the oxygen cylinder 30 has longer time to contact with water. The gas outlet 18 is on the top of the water tank 10 for the useless gas in the water tank 10 to escape.

A water source W is connected to the water inlet 12 of the water tank 10 to supply the water tank 10 with water through the pump 20. The water of the water source W is drinkable, such as RO water. It is preferable that the water of the water source W is low oxygenated water. The pump 20 is turned on or off according to a pressure in the water tank 10.

The controller 40 is able to open or close the water inlet 12 and the water outlet 14. The controller 40 has a circuit 42 and a panel 44. The panel 44 is electrically connected to the circuit 42 and has several buttons (not shown). People would operate the buttons of the panel to open or close the water inlet 12 and the water outlet 14.

As shown in FIG. 2, a method of supplying oxygenated water of the preferred embodiment of the present invention is performed on the system above, and the water tank 10 has oxygenated water therein. The method includes the following steps:

Close the water outlet 14, the gas inlet 16, and the gas outlet 18 of the water tank 10, and start the pump 20 to supply the water tank 10 with water through the water inlet 12. It will make a water level of the water in the water tank 10 rise, and a pressure in a space above the water level increase. When a first pressure S1 is sensed in the space above the water level, the pump 20 is turned off to stop the water supplying to the water tank 10. The first pressure S1 varies according to the size of the water tank 10, and usually is in a range between 5 atms and 20 atms.

The circuit 42 of the controller 40 is set by the designer to control the time of opening and closing the water outlet 14, so that the water tank 10 provides a constant amount of oxygenated water once. In an embodiment, the water outlet 14 is opened for 0.3 seconds when the pressure in the space above the water level is at the first pressure S1. 100 cc oxygenated water will be supplied in 0.3 seconds. In other words, when a user presses a supply button of the panel 44 once, the water tank 10 will supply 100 cc oxygenated water for the user to drink it up once. In an embodiment, there are buttons on the panel 44 to increase or decrease the amount of supplying oxygenated water once.

When the oxygenated water flows out through the water outlet 14, the water level lowers and the pressure in the space above the water level reduces. In an embodiment, the pump 20 is turned on to supply the water tank 10 with water once the water outlet 14 is opened, and the pump 20 is turned off when the pressure of the space above the water level is sensed to exceed a second pressure S2. The second pressure S2 is greater than or equal to the first pressure S1. It may keep a constant pressure in the water tank 10 to supply a constant amount of oxygenated water every time the user presses the supply button. In an embodiment, the pump 20 is turned on when the water outlet 14 is closed.

The method of the present invention supplies a constant amount of oxygenated water every time the user presses the supply button for the user to drink it up once.

It is easy to understand that the dissolution ratio of oxygen of the water in the water tank 10 reduces after the water outlet 14 being opened for the oxygenated water to flow out. In an embodiment, the method of the present invention further includes the step of holding the water outlet 14 closed for a holding time after the water outlet 14 is closed. After the predetermined amount of oxygenated water is supplied, the gas inlet 16 is opened to supply the water tank 10 with pure oxygen, and the pure oxygen may be dissolved in the water in the holding time. Therefore, there will be a constant dissolution ratio of oxygen in the oxygenated water which comes out from the water tank 10.

In order to make more pure oxygen to be dissolved in the water, the water tank 10 is provided with a postponing device to extend the time for the oxygen staying in the water tank 10. As shown in FIG. 3, the postponing device has a plurality of plates 19 transversely mounted in the water tank 10. The plates 19 respectively have an opening T, and the openings T are alternately on the left and right of the plates 19, so that a continuous S-shaped passageway is formed in the water tank 10. Each plate 19 is wave-shaped, so that each plate 19 has a plurality of exchanging rooms 19a thereunder. Oxygen may stay in the exchanging rooms 19a to be dissolved in the water when the Oxygen goes through the continuous S-shaped passageway. It is noted that any similar design in the water tank 10 to extend the time of the oxygen staying in the water tank 10 should be still in the scope of the present invention.

It must be pointed out that the embodiments described above are only some preferred embodiments of the present invention. All equivalent structures and manufacturing methods which employ the concepts disclosed in this specification and the appended claims should fall within the scope of the present invention.
