Description

BACKGROUND OF THE INVENTION

Field of Invention

[0001] The invention relates to a water processing device and, in particular, to a gas-liquid mixer for increasing the oxygen content of water by forming tiny bubbles for air inside the water.

Related Art

[0002] A conventional water purifying device 8, as shown in FIG. 10, has a water inlet 81 and a water outlet 82. The water to be purified enters the water purifying device 8 through the inlet 81. The purified water flows out via the outlet 82 for users to drink and use or to boil for drinking. However, the above-mentioned water purifying device 8 is usually used to simply filter out impurities inside water. It cannot increase the oxygen content in water.

[0003] Therefore, a tiny bubble water processing device 9, shown in FIG. 11, has been invented. It comprises a motor 91, a pressure bucket 92, and a high oxygen solving mechanism 93. The motor 91 pushes water to flow through a first channel 94 into the pressure bucket 92. The first channel 94 is provided with an air valve 95 for air to enter the first channel 94 and to flow with the water into the pressure bucket 92. The air and water stored in the pressure bucket 92 under a high pressure render the air bubbles solved in the water.

[0004] The high oxygen solving mechanism 93 is connected with the pressure bucket 92 via a second channel 96. The internal channel of the high oxygen solving mechanism is designed in such a way that the water flow speed is changed and the bubbles solved in the water become even smaller in size.

[0005] Although the above-mentioned tiny bubble water processing device 9 can increase the oxygen content in water, the components of the tiny bubble water processing device are too complicated. It relies on the pressure bucket 92 along with the high oxygen solving mechanism 93 to achieve the desired effect. Moreover, the oxygen is solved in water by taking in air once and imposing a high pressure. The effect is thus very limited.

SUMMARY OF THE INVENTION

[0006] An objective of the invention is to solve the above-mentioned problems by providing a gas-liquid mixer. Using a helical pipe, taking in air through an intake valve, and imposing a pressure with a pump, the air is solved in water and produces a lot of tiny bubbles.

[0007] To achieve the above-mentioned objective, the disclosed gas-liquid mixer performs gas-liquid mixing on a water source. It has the following features.

[0008] The gas-liquid mixer has at least one pump with a water inlet and a water outlet that are in fluid communications with each other and a helical pipe. The water enters the pump through the water inlet. The inlet has at least one air inlet valve. The water outlet is connected with a water supplying channel. The first air inlet valve guides air into the pump. When the pump imposes a pressure, the air and the water are mixed. The gas-liquid mixture is guided by the water outlet to the water supplying channel. The helical pipe is connected with the water supplying channel. When the gas-liquid mixed water flows from the water supplying channel into the helical pipe, the air and water further mix with each other by crossing and spiraling inside the helical pipe.

[0009] Moreover, the disclosed water supplying channel can be installed with an adjusting valve for gauging the water flowing into the helical pipe as well as adjusting the output pressure as the water flows from the water supplying channel into the helical pipe.

[0010] Besides, the disclosed gas-liquid mixer is provided with a gas-liquid mixing bucket. The gas-liquid mixing bucket has a water controlling valve for forming a closed space therein. The helical pipe is disposed inside the closed space. The water controlling valve has a water-entering portion and a water-leaving portion. The water-entering portion is in fluid communications with the water supplying channel and the helical pipe. The helical pipe is further provided with a high-pressure water outlet, so that the second-mixed water is ejected from there and perform a third gas-liquid mixing inside the closed space.

[0011] In addition, the gas-liquid mixing bucket has a second air inlet valve to guide air into the system for the second time. This enables a fourth gas-liquid mixing in the closed space.

[0012] The gas-liquid mixing bucket also has a plurality of granular filtering units for performing a second filtering on the water therein. The squeezing and collisions with the filtering units make the gas-liquid mixing more uniform and lasting. This helps increasing the oxygen content in water.

[0013] The water supplying channel can be installed with at least one horizontal filter. The helical pipe is then disposed in the horizontal filter. Both ends of the helical pipe are connected to a third water inlet and a third water outlet of the horizontal filter, respectively. This also produces water rich in oxygen.

[0014] Furthermore, the invention can have a pressured water storage bucket. It stores the water that has been first mixed by the pump. The pressured water storage bucket stores a pressure in order to perform a second pressure increase as water is output from the pressured water storage bucket.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

[0017] Please refer to FIG. 1. The disclosed gas-liquid mixer 1 is used to perform a gas-liquid mixing on water. It has the following features. The gas-liquid mixer 1 has at least one pump 11 with a water inlet 111 and a water outlet 112 that are in fluid communications with each other and a helical pipe 13. The water enters the pump 11 through the water inlet 111. The water inlet 111 has at least one air inlet valve 12. The water outlet 112 is connected with a water supplying channel 14. The first air inlet valve 12 guides air into the pump 11. When the pump 11 imposes a pressure, the air and the water are mixed for the first time, producing a lot of tiny oxygen-rich bubbles in the water. The gas-liquid mixture is guided by the water outlet 112 to the water supplying channel 14. In this embodiment, the pump 11 is a high-pressure pump. The first air inlet valve 12 is a retaining valve to prevent the water from flowing back to the first air inlet.

[0018] The helical pipe 13 is connected with the water supplying channel 14. When the gas-liquid mixed water flows from the water supplying channel 14 into the helical pipe 13, the air and water further mix with each other by crossing and spiraling inside the helical pipe 13.

[0019] The invention also has other embodiments that are only partially different from the first embodiment. Please refer to FIG 2 for a second embodiment. In this embodiment, the water supplying channel 14 is provided with an adjusting valve 3 for gauging the water flux and the water output pressure from the water supplying channel 14 to the helical pipe 13. The adjusting valve 3 is a retaining valve.

[0020] A third embodiment of the invention is shown in FIG. 3. In this embodiment, the gas-liquid mixer 1 further includes a gas-liquid mixing bucket 15. A water controlling valve 16 is disposed at the bottom of the gas-liquid mixing bucket to form a closed space 17 therein. The helical pipe 13 is disposed in the closed space 17. In this embodiment, one end of the helical pipe 13 is mounted on the water controlling valve 16. The water controlling valve 16 has a water-entering portion 161 and a water-leaving portion 162. The water-entering portion 161 is connected with the water supplying channel 14 the helical pipe 13 mounted on the water controlling valve 16. The water-leaving portion 162 has a guiding hole 163 connected with the closed space 17 of the gas-liquid mixing bucket 15.

[0021] The helical pipe 13 further has a high-pressure water outlet 18. The high-pressure water outlet 18 has an opening end 181 with a flat shape. The gas-liquid mixing is done in the helical pipe 13, and then output from the opening end 181 of the high-pressure water outlet 18.

[0022] Due to the flat shape of the opening end 181 of the high-pressure water outlet 18, the pressure of water increases when it reaches the opening end 181. The water is thus ejected from the high-pressure water outlet 18 at a high pressure and directly hits one side of the closed space 17 of the gas-liquid mixing bucket 15. In this embodiment, the high-pressure water outlet 18 corresponds to one side of the top edge of the gas-liquid mixing bucket 15.

[0023] Moreover, water molecules change their original moving direction as they hit the gas-liquid mixing bucket 15. This change in the water flow direction enables the water to produce turbulence inside the gas-liquid mixing bucket 15, rendering a third gas-liquid mixing. As a result, there are more tiny bubbles in the water.

[0024] To increase the purifying and gas-liquid mixing effects, the disclosed gas-liquid mixing bucket 15 is disposed with a plurality of granular filtering units 19 to further filter the water therein. By colliding wit the filtering units 19, the gas-liquid mixing is more uniform and lasting. Therefore, the oxygen content of water is increased.

[0025] The water after the above-mentioned three gas-liquid mixings contains a huge amount of tiny bubbles. Therefore, a lot of air has been mixed into the water to increase its oxygen content. Afterwards, the water is guided by the guiding hole 163 of the water controlling valve 16 to leave via the water-leaving portion 162.

[0026] A fourth embodiment of the invention is illustrated in FIG. 4. It is different from the third embodiment in that the high-pressure water outlet 18 goes through the central region of the helical pipe 13. The gas-liquid mixing bucket 15 further has at least a second air inlet valve 151. In this embodiment, the second air inlet valve 151 is a retaining valve to guide more air into the closed space 17 for a fourth mixing. This further enriches the oxygen content of water.

[0027] As shown in FIG. 5, in a fifth embodiment of the invention, the water-leaving portion 162 of the water controlling valve 16 on the gas-liquid mixing bucket 15 is connected with toilet equipment 2 that has at least one faucet 21. The water processed by the gas-liquid mixer 1 is guided to the faucet 21. Thereby, the toilet equipment 2 can provide water full of tiny bubbles and rich in oxygen. The helical pipe 13 can be directly mounted inside a filter pipe (not shown) on the market for uses.

[0028] According to the above-mentioned embodiments, the invention has the following features. Air and water enter the pump 11 simultaneously. The pump 11 imposes a pressure to mix the air and water. The mixture then enters a helical pipe 13 at a higher pressure for a further gas-liquid mixing. Afterwards, it goes through a high-pressure water outlet 18 and enters the gas-liquid mixing bucket 15 by high-pressure injection. Using the first and second air inlet valves 12, 151 and the filtering units 19, the air and the water can be mixed more uniformly. This does not only greatly increase the oxygen content of water, but produces a huge amount of tiny bubbles in the mixed water.

[0029] A sixth embodiment of the invention is shown in FIG. 6. The gas-liquid mixer 1 is installed on a filter 3 to perform gas-liquid mixing on the water output by the filter 3. The filter 3 has a first water inlet 31 and a first water outlet 32. The water inlet 111 of the pump 11 in the gas-liquid mixer 1 is connected with the first water outlet 32 of the filter 3. Therefore, the water first passes through the filter 3, and then enters the pump 11 via the water inlet 111. Through the action of the gas-liquid mixer 1, the oxygen content and the amount of tiny bubbles in the drinking water are greatly increased.

[0030] Please refer to FIG. 7 for a seventh embodiment of the invention. It differs from the sixth embodiment in that the water supplying channel 14 is provided with at least one horizontal filter 4. The helical pipe 13 is disposed inside the horizontal filter 4. Both ends of the helical pipe 13 are connected to a second water inlet 41 and a second water outlet 42 of the horizontal filter 4.

[0031] As shown in FIG. 8, an eighth embodiment of the invention differs from the seventh embodiment in that a pressured water storage bucket 5 is inserted between the water supplying channel 14 and the horizontal filter 4. It stores the water that has been done with the first gas-liquid mixing in the pump 11. The pressured water storage bucket 5 stores a pressure for a second pressure enhancement on the outgoing water.

[0032] A ninth embodiment shown in FIG. 9 is different from the fourth embodiment in that a flow splitting connector 31 is disposed at the water outlet 112 to divide the water output from the water outlet 112 into the water supplying channel 14 and a second water supplying channel 32. The second water supplying channel 32 is connected to the second air inlet valve 151 on top of the gas-liquid mixing bucket 15. The water in the second water supplying channel 32 flows into the gas-liquid mixing bucket 15 via the second air inlet valve 151. Therefore, when the water level in the gas-liquid mixing bucket 15 gradually increases as the helical pipe 13 continues supplying water, the air in the shrinking closed space 17 therein is squeezed. The water entering from the top of the gas-liquid mixing bucket 15 thus mixes with the squeezed air in the closed space 17, greatly increasing the oxygen content of the water.

[0033] If the invention is used in an aquarium, aquacultural fields or aquaculture-related industries, there is no need to prepare other large air-exchange devices or pumps because the disclosed gas-liquid mixer can increase the oxygen content of water. Not only does the invention reduce the cost, it also saves the space for installing large air-exchange devices.

[0034] Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
