Document Type and Number:
Japanese Patent JP6863320
Kind Code:
B2
Abstract:
To provide a volatile component discharging device which can perform discharge of a volatile component exactly.SOLUTION: A volatile component discharging device (S) arranged in the air flow, comprises: a cylindrical body (10) which accommodates a vaporization source (k1) retaining the volatile component and extends from an upstream side to a downstream side of the air flow; a first valve (11) which changes the opening degree of an upstream side opening of the cylindrical body; a second valve (12) which changes the opening degree of a downstream side opening of the cylindrical body; drive means (13, 15) which drive the first valve and the second valve; and a flow divider which is arranged on an upstream side of the second valve, introduces a part of the air flow into the first valve side, and passes a remainder of the air flow. The flow divider is, for example, a resistance plate (8) on which a plurality of through holes (82) passing the remainder of the air flow are arranged and which increases an atmospheric pressure of the upstream side rather than the downstream side.SELECTED DRAWING: Figure 1
