Abstract

An electrostatic atomization device comprises an atomization unit provided with a microstrip line having first and second ends, a microwave input unit configured to input a microwave signal to the first end, and a liquid supply means configured to supply liquid to the second end side. Consequently, the emission of ozone with charged particulate water containing an active ingredient can be suppressed while the amount of generation of the charged particulate water is ensured.

Description

technical field [0001] The invention relates to an electrostatic atomization device. Background technique [0002] Conventionally, there is known an electrostatic atomization device capable of generating charged fine particle water containing active ingredients such as radicals. In this electrostatic atomization device, a voltage application unit is connected to a needle-shaped atomization unit, and a high voltage is applied to the atomization unit in a state where a liquid is held, thereby electrostatically atomizing the liquid to generate charged fine particles Water (for example, see Japanese Patent Application Laid-Open No. 2006-272092 and the like). [0003] In the case where the aforementioned electrostatic atomization device generates a large amount of charged fine particle water containing an active ingredient, a large amount of energy is applied to the atomization unit in response to the amount. [0004] As described above, in the case where a conventional electro...
