Abstract: An electrostatic atomization device that prevents the cooling capability from being lowered due to contact of an atomization electrode with another ember, while effectively preventing surplus production of condensed water that would destabilize discharging at the distal end of the atomization electrode. the electrostatic atomization device includes an atomization electrode having a cylindrical electrode body and a base which is informed at a basal end of the electrode body and has a larger diameter than the electrode from the base to produce condensed water on the atomization electrode. Voltage is applied to the atomization electrode when the condensed water is produced to generate charged fine water droplets. A partition plate includes an insertion hole that receives the electrode body of the atomization electrode. The partition plate and the base of the atomization electrode form a water collection region in between.

Abstract: An electrostatic atomization device having a simple structure and allowing for reduction in size. The electrostatic atomization device has an atomization electrode including a P type Peltier element and an N type Peltier element joined with the P type Peltier element. The atomization electrode is cuspate so as to form a projection with a joined portion of the P type Peltier element and the N type Peltier element. High voltage is applied to the P and N type Peltier elements so that discharging occurs at a distal portion of the atomization electrode, current flows to the P and N type Peltier elements to produce a cooling effect at the joined portion, and condensed water generated by the cooling effect is atomized by the discharging to generate charged fine water droplets.

Abstract: Disclosed is a discharge device (20) which comprises a power supply unit (22) that supplies a first voltage, a piezoelectric transducer (24) that increases the first voltage to a second voltage by means of vibrations, and a first electrode (26) for producing a discharge product (P) by performing a discharge upon application of the second voltage. The first electrode (26) and the piezoelectric transducer (24) are electrically connected with each other via a vibration damping unit (30). In other words, the first electrode (26) and the piezoelectric transducer (24) are arranged to be out of contact with each other.
