a spiral tube which communicates with the water supply channel such that the gas-liquid mixed water source contained in the water supply channel flows into the spiral tube for gas-liquid mixing once again allowing the air and the water source to swirl and mix within the spiral tube, and the oxygen-rich water source is transported from the spiral tube.
Moreover, according to the present invention, a regulating valve can be additionally disposed in the water supply channel to regulate the water flow capacity from the water supply channel to the spiral tube and simultaneously regulate the outlet water pressure from the water supply channel to the spiral tube.
In addition, the water supply channel can be additionally provided there in with a pressurized water storage tank for storing the water source which has undergone the first gas-liquid mixing through the pump, and the pressurized water storage tank builds up the pressure to pressurize the water source for the second time when transported from the pressurized water storage tank.
Also, the water supply channel can be provided therein with at least one horizontal filter and the spiral tube is placed within the horizontal filter, and the both ends of the spiral tube are respectively connected with a third water inlet and a third water outlet disposed at the horizontal filter so as to obtain the oxygen-rich water source.
Furthermore, according to the pre sent invention, the gas-liquid mixing device is further provided with a gas-liquid mixing tank, and the gas-liquid mixing tank is provided with a gate valve seat to form an enclosed space within the gas-liquid mixing tank and the spiral tube is disposed in the enclosed space, and the gate valve seat has a water inlet portion and a water outlet portion, and the water inlet portion communicates with the water supply channel and the spiral tube. The spiral tube is further provided with a high-pressure water outlet to eject the second gas-liquid mixed water source from the high-pressure water outlet and perform the third gas-liquid mixing in the enclosed space.

A pump 21 which has a second water inlet 211 and a second water outlet 212, and the second water inlet 211 communicates with the first water outlet 12, and at least a first gas inlet valve 23 is disposed between the second water inlet 211 and the first water outlet 12, and the second water outlet 212 communicates with a water supply channel 22, and air is introduced by means of the first gas inlet valve 23 and enters the pump 21 such that the pump 21 pressurizes the air and the water source to perform the gas-liquid mixing for the first time and to generate a lot of fine oxygen-containing bubbles in the water source. After that, the water source containing many fine bubbles is transported from the second water outlet 212 to the water supply channel 22. In this embodiment, the pump 21 is, for example, a high-pressure pump, and the first gas inlet valve 23 is a check valve to prevent the backflow of the water source and allow it to flow from the first gas inlet valve 23.
A spiral tube 24 which communicates with the water supply channel 22 and the water supply channel 22 contains the first gas-liquid mixed water source so that the water source flows into the spiral tube 24 and is subjected to the second gas-liquid mixing in the spiral tube 24. Since the air and the water source swirl and mix within the spiral tube 24, the air can be mixed into the water more homogeneously, and the oxygen-rich water source can be transported from the spiral tube 24.
In view of the above, the combination of the spiral tube 24, the pump 21 and the first gas inlet valve 23 in this embodiment can achieve the effect of increasing the oxygen content in water.
It is understood that the present invention still has other variants those are only different from some changes. Referring to

The spiral tube 24 further comprises a high-pressure water outlet 28, and the high-pressure water outlet 28 has a flat open end 281 to deliver the water source as mentioned in the above embodiments from the open end 281 of the high-pressure water outlet 28 after gas-liquid mixing in the spiral tube 24.
The open end 281 of the high-pressure water outlet 28 is flat-shaped so that the flow channel is convergent. Therefore, when the water source flows to the open end 281, the pressure will increase. This results in that the water stream is ejected from the high-pressure water outlet 28 in the form of high-pressure spray and impacts on the one side of the enclosed space 27 of the gas-liquid mixing tank 25. In this embodiment, the high-pressure water outlet 28 corresponds to one side of the head of the gas-liquid mixing tank 25.
Furthermore, water molecules would change their direction of movement while colliding with the gas-liquid mixing tank 25 so that the direction of the high-pressure water stream impacting on the gas-liquid mixing tank 25 will be changed and turbulent flows will occur in the gas-liquid mixing tank 25 to advantageously perform the third gas-liquid mixing. Numerous finer bubbles will form in the water source after the gas-liquid mixing.
Additionally, in order to improve the effects of water purification and gas-liquid mixing, a plurality of granular filter units 29 are placed into the gas-liquid mixing tank 25 to filter the water source in the gas-liquid mixing tank 25 once again, and the filter units 29 collide and squeeze with one another to allow more durable and homogeneous gas-liquid mixing, thus increasing the oxygen content in the water.
The foregoing gas-liquid mixed water source for three times has contained a large amount of fine bubbles, that is, a large amount of air has been mixed into the water source and increases the oxygen content in the water so that the water source can be guided by the diversion hole 263 of the gate valve seat 26 to the water outlet portion 262 and be drained.
Next, referring to
From the above embodiments, the advantages of the present invention are as follows: air and a water source simultaneously enter the pump, and the pump pressurizes the air and the water source for mixing and enables the pressurized gas-liquid mixture to enter a spiral tube for gas-liquid mixing once again and then to pass through a high-pressure water outlet and to be ejected into the gas-liquid mixing tank in the form of high-pressure water stream. The arrangement of the filter units in coordination with the first and second gas inlet valves can allow the air and the water source to mix more homogeneously. Not only does the oxygen content in water significantly increase, but also the mixed water source contains a large amount of fine bubbles, thereby enhancing human absorption.
Moreover, if the present invention is applied to aquariums, aquafarms or the related aquiculture, due to the increased oxygen content in water, there is no need for the arrangement of large ventilators to pump air in. Therefore, the additional space required for the installation of the large ventilators can be reduced in addition to the lowered manufacturing costs.
