本発明は、超音波を利用して水を霧化する足音被加湿器

た折り返し部４を有している。(Prior art) Figures 2 and 3 show the basic configuration of this type of ultrasonic humidifier vibrator, in which a disc-shaped vibrator element 1 made of piezoelectric ceramic
A first silver electrode 2 is provided on the ultrasonic emission surface of the electrode, and a second silver electrode 3 is provided on the opposite surface by baking. The first silver electrode 2 serves as an ultrasonic emission electrode, and has a folded portion 4 that partially extends toward the opposite surface on which the silver electrode 3 is provided.

保護膜としてニッケルメッキを施していた。By the way, in the basic configuration shown in FIGS. 2 and 3, a problem arises in the corrosion resistance of the silver electrode 2 on the ultrasonic emission side, so nickel plating has conventionally been applied as a surface protection film.

溶液を用いることは振動子寿命を着しく短くしてしまう
問題が生ずる。(Problems to be Solved by the Invention) However, the following problems occur when the protective film is formed by nickel plating. In other words, when hard water is used in an ultrasonic humidifier (hard water is common in Europe and the United States), a large amount of water scale adheres to the surface of the vibrator, reducing the atomization ability. . To prevent this, the user cleans the vibrator with a weak acid solution called vinegar (equivalent to a 5% acetic acid aqueous solution), but this causes corrosion of the electrodes on the surface of the vibrator. That is, it has been found that the nickel metal protective film corrodes in a 5% acetic acid aqueous solution, and when left in a 5% acetic acid aqueous solution, it dissolves within 100 hours to 200 hours. For this reason, the use of a 5% acetic acid aqueous solution called vinegar to remove limescale poses the problem of seriously shortening the life of the vibrator.

しようとするものである。(Means for Solving the Problems) In view of the above points, the present invention significantly improves the corrosion resistance against weak acids by configuring the surface protective film of the ultrasonic radiation electrode with an alloy film of tungsten and nickel. Therefore, it is an object of the present invention to provide a vibrator for an ultrasonic humidifier, which makes it possible to use a weak acid solution such as acetic acid to remove attached water scale, and which is also effective in removing limescale.
