Abstract
A nebulizer kit includes a case body having a compressed air introduction tube in an upper end portion of which is a nozzle hole that expels compressed air, a suction channel formation member forming a suction channel for sucking liquid toward the upper end portion and forming an atomizing area in an exit region of the hole, and a flow channel formation member having an aerosol discharge port. The suction channel has first and second suction channels respectively extending upward along an outer circumferential surface of the tube and from the suction channel toward the hole at a leading end area of the tube and has a liquid suction port that expels the liquid. A particle segregating portion having a blade portion, whose orientation to the atomizing area is adjustable, is between the atomizing area and the port. The suction channel formation member is fixed to the case body.
