发明名称 Air blowing device
摘要 There is provided an air blowing device that is easy to carry and is convenient, the air blowing device that has little adverse effect on the blowing function and is configured to be able to disperse electrically-charged particles while ensuring safety.;A fan 4 coupled to an output shaft 33a of a motor 33 is rotated by the motor 33 to send air. The motor 33 is housed in a motor housing portion 3, and a fan cover rear separate body 72 in the shape of a flange, the fan cover rear separate body 72 covering an outer edge portion of the fan 4 and a lateral part of the fan 4 on the side where the motor 33 is located, is fixed to an end of the motor housing portion 3 on the side where the output shaft 33a is located. A handle portion 2 is provided in a standing manner in an intermediate portion of the output shaft 33a in a direction of an axis thereof on an outer surface of the motor housing portion 3, and the fan cover rear separate body 72 has a tapered portion T which faces the handle portion 2 and whose outer peripheral side is inclined toward the fan 4. A passage 25 that allows air to pass therethrough is provided in an intermediate portion of the handle portion 2, and an ion generator 9 that generates positive and negative ions to be released into the passage 25 is provided in the handle portion 2 in a base end portion thereof.
