Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a microbubble water generator, in particular to one applying a booster pipe to promote an admixture of gas and liquid for giving a rinsing object. 
         [0003]    2. Description of the Related Art 
         [0004]    A conventional bubble water generator commonly serves to directly introduce gas into water and allows the admixture of gas and water therefrom, which is so called the microbubble water. A typical technique especially includes a motor assembly mounted inside the generator and utilizes the rotation of a motor fan attempting to stir gas into water and so to attain bubble particles smaller than ones created by directly mixing gas and water. Whereas, the problem is that the bubble particles are not in a constant shape, so the typical invention still fails to efficiently diffuse the gas throughout the water in an even and tenuous manner and substantially confines effects on the application to water quality improvement, decomposition of pesticide remained on vegetables and fruits, cleaning of industrial instruments and family appliances, decomposition of organic contamination in water, and destruction of microorganism. 
         [0005]    The above typical inventions can merely create the irregular bubble particles and maintain a short-period bubble life. Whereas, concerning a preferable microbubble water generator, it should obtain the condition of efficiently create fine and even bubble to coincide with the market&#39;s demand. 
         [0006]    As in a prior invention,  ┌ NANO OZONIC MICROBUBBLE WATER GENERATOR AND THE METHOD OF THE SAME ┘  published by R.O.C. Patent No. I298644, mainly directed to a generator applies a water pipe connected with a pressure conveying motor to render the pressurized water traveling a gas absorbing device through pipes and thence cause a negative pressure. The water would absorb ozone mixture created by an ozone generator for an initial admixture. The admixture of gas and water thence enters a closed counterpressure container for processing a step of dissolution, which hence completely dissolves ozone mixture in the water to become aqueous solution with high consistency of gas. The aqueous solution is guided from the pipes toward a pressure release valve, and so it could become multiple tiny nano bubbles as a result of relieving the solution of the pressure to quickly free the dissolved gas in the water. Accordingly, those nano bubbles are used to effect the promotion of decomposition of pesticide remained on vegetables and fruits, cleanser of kitchen appliances, decomposition of organic contamination in water, and destruction of microorganism. However, such invention suffered for a critical problem of the counterflow of water. Due to the fact that the generator mainly use a pressure switch to control the operating state of the pressure conveying motor, when turning off the water output, the water pressure inside the pipes would inevitably raise to bring the water back to the ozone generator and even damage it. Further, the concern of over-low flow speed of water would be unable to create the negative pressure and also result in an uneven gas volume within the water, thus still require improvements. 
       SUMMARY OF THE INVENTION 
       [0007]    Therefore, the object of the present invention is to solve the aforementioned problems and to provide a microbubble water generator, which includes a gas absorbing device comprising a liquid entrance, a gas entrance, and an admixture exit; a pressure conveying motor comprising a first pipe connected with the admixture exit of the gas absorbing device and a second pipe disposed thereon; a gas supplier comprising a third pipe connected with the gas entrance of the gas absorbing device; a water switch disposed on a fourth pipe, wherein, the fourth pipe is jointed to the liquid entrance of the gas absorbing device, and the water switch has a detecting unit disposed thereon as well as inserted into an interior of the fourth pipe, and the water switch is electrically connected with the pressure conveying motor and the gas supplier; a booster pipe communicating with the pressure conveying motor and having an input end and an output end, wherein, the input end is connected with the second pipe of the pressure conveying motor; a pressure release coupling communicating with the output end of the booster pipe, wherein, the pressure release coupling has a partition therein, the partition includes at least one pore defined thereon, and further, the pressure release coupling is connected with a fifth pipe; and a water output valve communicating with the fifth pipe of the pressure release coupling. 
         [0008]    Preferably, the liquid entrance of the gas absorbing device is formed of a gradually narrower contour. 
         [0009]    Preferably, an anti-reflux valve is disposed in the gas entrance. 
         [0010]    Preferably, a gas diffusing pipe extends outward from the second pipe and includes a plurality of apertures defined thereon. 
         [0011]    Accordingly, the present invention has following advantages:
   1. The present invention substantially attains microbubble water with even and tenuously fine properties for a preferable utilization.   2. The present invention is allowed to incessantly produce high consistency of microbubble water in the water. Accompanying the cooperation with air, oxygen, or ozone, the present invention preferably serves to adapt to the application of water quality improvement, decomposition of pesticide remained on vegetables and fruits, cleaning of industrial, medical and kitchen instruments as well as appliances, body cleanness, decomposition of organic contamination in water, and destruction of microorganism.   3. By virtue of the tiny bubbles created by the present invention lagging in the water to prolong the stay of bubbles in the water, a preferable reaction between bubble gas and remnant chemical components, microorganism, organic pollutants, an assortment of equipments, as well as human body could be attained.   4. The admixture of gas and water produced by the present invention is of quasi-white color analogous with milk, which permits the microbubbles to fully contact with various objects in irregular shapes and to invade into overall interstices for attaining a preferable reaction.   5. The present invention preferably adds a gas diffusing pipe connected to the input end of the booster pipe, on which apertures are disposed. Accordingly, the liquid could smoothly pass through the apertures for shaping into fine bubbles and thence enter the booster pipe for acting as dissolution and diffusion.   6. The pores on the partition of the pressure release coupling allow the gas and liquid to be remixed and rediffused, so as to promote the dissolution and diffusion of gas. The gas could be completely and maturely dissolved in the liquid and evenly dispersed among the liquid.   7. The liquid entrance of the gas absorbing device having a gradually narrow opening defined thereon facilitates to speed up the flowing of introduced liquid, and so a negative pressure could be achieved by smaller volume of water.   8. The present invention takes advantage of the pressure release coupling to control the water pressure and output volume of the booster pipe, and preferably, the output volume thereof could coincide with the output volume of the pressure conveying motor.   9. The present invention utilizes the water switch to synchronously control a pressurization of the pressure conveying motor and trigger the gas supplier to introduce gas. In time of outputting liquid, the pressure conveying motor and the gas supplier are simultaneously actuated for mixing the introduced liquid and gas. Hence, the present invention avoids the problem of unintentional inputting over stopping outputting water and prevents over-raising pressure caused by the above problem from damaging elements of the generator.   10. The present invention is assembled by fewer components and mechanical parts, which thence reduces costs and decreases failures.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0026]    Referring to  FIG. 1 , a microbubble water generator in conformity with the present invention includes a gas absorbing device  1 , a pressure conveying motor  2 , a gas supplier  3 , a water switch  4 , a booster pipe  5 , a pressure release coupling  6 , and a water output valve  7 . 
         [0027]    The gas absorbing device  1  comprises a liquid entrance  11 , a gas entrance  12 , and an admixture exit  13  which are communicated with each other. The liquid entrance  11  has an interior opening formed of a gradually narrower contour, so as to speedup the flowing of introduced liquid and thence create a negative pressure. Furthermore, the gas entrance  12  has an anti-reflux valve  14  disposed therein for entrance of gas without counterflow. 
         [0028]    The pressure conveying motor  2  communicates with the gas absorbing device  1 . The pressure conveying motor  2  comprises a first pipe  21  and a second pipe  22 . The first pipe  21  is connected with the admixture exit  13  of the gas absorbing device  1 . Preferably, a gas diffusing pipe  23  extends outward from one end of the second pipe  22  and includes a plurality of apertures  24  defined thereon as shown in  FIG. 2 , so that after a pressurization upon the liquid introduced by the first pipe  21 , the pressurized liquid could then pass through the apertures  24  of the gas diffusing pipe  23  of the second pipe  22  to become liquid with bubbles. 
         [0029]    The gas supplier  3  communicates with the gas absorbing device  1 . The gas supplier  3  comprises a third pipe  31  connected with the gas entrance  12  of the gas absorbing device  1 . The gas supplier  3  could be an aerating instrument, an oxygen maker, an ozone maker, or other proper devices for supplying air, oxygen, or ozone into the subject generator. 
         [0030]    The water switch  4  communicates with the gas absorbing device  1 . The water switch  4  is disposed on a fourth pipe  41 . The fourth pipe  41  is jointed to the liquid entrance  11  of the gas absorbing device  1 . The water switch  4  has a detecting unit  42  disposed thereon. The detecting unit  42  inserts into an interior of the fourth pipe  41  for detecting the flowing state of the liquid inside the fourth pipe  41 . Additionally, the water switch  4  is electrically connected with the pressure conveying motor  2  and the gas supplier  3 . When the detecting unit  42  of the water switch  4  is subjected to a flush of the liquid inside the fourth pipe  41 , the water switch  4  is thence triggered for commanding the pressure conveying motor  2  to start pressurizing and for controlling the gas supplier  3  to convey gas. 
         [0031]    The booster pipe  5  communicates with the pressure conveying motor  2 . The booster pipe  5  has an input end  51  and an output end  52 . The input end  51  is connected with the gas diffusing pipe  23  of the second pipe  22  of the pressure conveying motor  2 , so as to receive the liquid already blended with gas from the pressure conveying motor  2 . 
         [0032]    The pressure release coupling  6  communicates with the output end  52  of the booster pipe  5 . The pressure release coupling  6 , as illustrated in  FIG. 3 , has a partition  61  therein. The partition  61  includes at least one pore  62  defined thereon, thereby serving to output microbubble water. In addition, the pressure release coupling  6  is further connected with a fifth pipe  63 . 
         [0033]    The water output valve  7  communicates with the fifth pipe  63  of the pressure release coupling  6  for controlling the output of liquid with microbubbles. 
         [0034]    Referring to  FIGS. 1 to 4 , in operation, when turning on the water output valve  7  to output liquid, the liquid would be initially introduced from the fourth pipe  41  as a result of pressure difference. At the same time, the detecting unit  42  of the water switch  4  would suffer for the flush of the liquid inside the fourth pipe  41 , and thence the water switch  4  would be triggered for commanding the pressure conveying motor  2  to start pressurizing and controlling the gas supplier  3  to convey gas. In view of the liquid entrance  11  providing an interior opening formed of a gradually narrower contour, the flowing of the liquid could be speed up for thence creating a negative pressure. Besides, the gas supplier  3  feeds gas to the third pipe  31 , then through the gas entrance  12  and the anti-reflux unit  14 , and thence into the gas absorbing device  1 , in which the gas and liquid would proceed an initial mixture. Thereafter, the admixture of gas and liquid passes through the admixture exit  13  and the first pipe  21  and enters the pressure conveying motor  2 . While passing through the apertures  24  of the gas diffusing pipe  23  at one end of the second pipe  22 , the liquid would become tenuous and tiny bubbles and thence go into the booster pipe  5  along the input end  51  for proceeding dissolution and diffusion. The booster pipe  5  substantially prolongs the flowing of the liquid and conveys it toward the pressure release coupling  6  via the output end  52 , and so the liquid would pass through the pores  62  on the partition  61  of the pressure release coupling  6  for remixing and redispersing the gas and the liquid, which facilitates the dissolution and diffusion of the gas. Accordingly, the gas could be absolutely dissolved in the liquid and evenly spread throughout the liquid, hence forming liquid with high consistency of gas. Once such liquid passes from the pressure release coupling  6  into the water output valve  7  along the fifth pipe  63 , multiple tiny nano bubbles could be generated while relieving the liquid of the pressure to quickly free the dissolved gas in the water. Thence, the microbubble water is produced. It should note that such microbubble water is milk-white color due to the component of nano bubbles, which could be held in a tank A for adapting to the application of water quality improvement, execution of hydrotherapy, decomposition of pesticide remained on vegetables and fruits, cleaning of industrial as well as kitchen appliances, decomposition of organic contamination in water, and destruction of microorganism.
