Abstract
An antigen supply deviceaccording to the present invention is mainly configured by a cylindrical memberextending in the vertical direction. An air suction portfor sucking the air in the antigen exposure chamber is provided at a lower end of the cylindrical member. An axial fanthat generates a flow of the air flowing upward in an axial direction of the cylindrical member is attached above the air suction port of the cylindrical member. Moreover, a supply portthrough which high-concentration antigens are jetted from a dust feeder on the outside of the antigen exposure chamber is provided above the axial fan of the cylindrical member. The antigen supply deviceis disposed near the outdoor air diffuser of the antigen exposure chamber, and configured to blow out high-concentration antigens, which are supplied from the dust feeder on the outside of the antigen exposure chamber, to the outdoor air diffuserfrom an upper end of the cylindrical member after mixing the antigens with the air in the antigen exposure chamber sucked from the air suction port and diluting the antigens, and moreover mix the antigens with the outdoor air from the outdoor air diffuser to fill the antigen exposure chamber A with the mixture of the antigens and the outdoor air.
