| 摘要 |
The invention relates to an easy to produce ultrasonic vaporiser, whereby desired oscillating modes can be excited in a specific manner. Said vaporiser comprises a piezoelectric oscillator (10) which is formed as a flat panel and is connected to a substrate panel (12). Said substrate panel (12) advantageously comprises at least one recess (14) whose geometric variables such as length, width, surface or diameter are selected in a specific manner so that the working frequency of the unit which contains the piezoelectric oscillator (10) and the substrate panel (12) is fixed. Said ultrasonic vaporiser has a particular advantage in that it produces a spray of mist in an electric iron (40). |
