Abstract
In many fields, such as medicine and cosmetics production, it is an important proposition to generate small and uniform droplets of various liquids. In order to realize these droplets' generation, we have been using a bolt-clamped Langevin-type transducer and a micropore plate. The purpose of this study is to fabricate a bolt-clamped Langevin-type transducer having separated structure for cleaning, and to generate droplets by using this device. First, we have proposed a new structure, and designed a bolt-clamped Langevin-type transducer which consists of some separated parts. Next, we have generated and evaluated droplets in the air by using pure water. When the micro pore diameter, the applied air pressure and the resonance frequency were 50μm, 100kPa and 37kHz, the average diameter of pure water droplets and standard deviation of diameter were 169.1μm and 3.44, respectively.
