Patent ID: 7497556

Claim:
A mist spraying apparatus, comprising: a liquid chamber into which liquid is filled; a coil which is applied with an electrical signal to generate a magnetic filed, the electrical signal having a frequency corresponding to an ultrasonic wave; a diaphragm which is vibrated by the magnetic field generated by the coil, and imparts the ultrasonic wave to the liquid in the liquid chamber; a spraying port which is connected to the liquid chamber and sprays the liquid converted into a mist by the ultrasonic wave; a drive unit which applies the electrical signal to the coil; a first magnetic body which is disposed inside the coil; and a second magnetic body which is arranged on the diaphragm in a separated position from the first magnetic body, wherein the diaphragm vibrates due to a magnetic force between the first magnetic body and the second magnetic body, when the first magnetic body is magnetized by flow of current of the electrical signal in the coil.
