IPC: A61L2/16
Filed: 2000-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a device and method for forming waterdrops of large and medium ions to remove them and separating small ion air in gas ionization of water. SOLUTION: The substantial portion of this air ion separating device has a double concentric pipe structure as shown in Fig. 1. The double concentric pipe structure has a vent hole, through which air can pass, in the center thereof and constituted by a trumpet plate 1 having a structure in which liquefied water is allowed to flow downward, an inner pipe 2 and an outer pipe 3. Fig. 2 shows a specific attachment example using this structure. Water injected from a water chamber 4 to a water absorption unit (water flow passage) 5 flows to an ultrasonic transducer 7b disposed in a water tank of a water ion particle generating unit 7 through a silver-added, weathered and sintered coral ceramics 6a in a silver-added coral ceramic cartridge 6.  When a high vibrational energy is applied to the water in the water tank 7a at the bottom of a case C by the ultrasonic transducer 7b, the water is decomposed and gasified in an atomized state. Gasified water ion particles I are rotated in a sealed space by a wind force from a rotary fan 8 and thereby Brownian motion is intensely caused. Thus, medium and large ions are liquefied and thereby the number of small negative ions is increased.
