US 7,350,317 B2 · Electrostatic atomizing hairdryer and electrostatic atomizer

Abstract

In an electrostatic atomizing hairdryer, electrostatically atomized mist generated in an electrostatic atomizing unit is effectively scattered into airflow emitted from a main body of the hairdryer so that the mist can be sprayed to hair uniformly and a time necessary for treatment of hair can be shortened. A tank constituting the electrostatic atomizing unit is detachably provided on a portion in the vicinity of an outer periphery of the main body, and an electrode unit for generating the mist is provided in a path of airflow sucked in an inside of the main body so as to be insulated from heat of a heating unit by an adiabator. A mist emitting opening from which the mist is emitted is disposed on a plane substantially the same as and at substantially the center of an air exit opening of the main body. Thereby, the mist emitted from the mist emitting opening is effectively scattered into the airflow emitted from the air exit opening.

Dependent claims

An electrostatic atomizing hairdryer comprising:

a main body having an air suction opening and an air exit opening;
a blower provided within the main body, wherein the blower is configured to draw air into an inside of the main body through the air suction opening so as to generate airflow in the inside of the main body, and wherein the blower is configured to emit the air, drawn into an inside of the main body, through the air exit opening;
a heater which heats at least part of the airflow generated by blower;
and
an electrostatic atomizer comprising:
a tank which stores a non-combustible liquid;
a mist generator which generates mist by electrostatically atomizing the non-combustible liquid;
and a mist emitting opening which emits the mist, wherein the mist emitting opening is provided in a path of the airflow generated by the blower, so that the mist emitted from the mist emitting opening is scattered into the airflow emitted from the air exit opening.
