Charged particle emission device and air-blowing device

摘要

A charged particle emission and air-blowing device includes a communication port biased toward an end portion in a predetermined direction with respect to an air outlet, and a width expander configured to widen a flow path between an air directing plate of the end portion and a second blowing duct wider than a periphery. Emitted light from a light guide plate is reflected by the air directing plate in the delivery direction of an air flow. An air flow passes from a downward direction to an upward direction along a circuit board in an auxiliary suction path, and an opening portion faces the upper portion of the circuit board.

主权项

1. A charged particle emission device, comprising:
a housing including a suction port and an air outlet; a blower fan in the housing; a first blowing duct on an exhaust side of the blower fan; a second blowing duct in which an air outlet is opened at one end and configured to communicate with the first blowing duct via a communication port; a charged particle generating element configured to release charged particles in the first blowing duct; a wind direction plate configured to radially guide an air flow and located opposite to the air outlet; and a width expander configured such that the communication port is biased with respect to the one end in a predetermined direction with respect to the air outlet, and configured such that the width expander widens a flow path between the second blowing duct and the air directing plate on the one end wider than a periphery.
