It can be impregnated with a volatilizing agent. That is, since the outer periphery of the discharge head 13 is covered with the cylindrical impregnated body 21, when the volatilizing agent is discharged from the nozzle 13 c of the discharge head 13, the volatilizing agent is sprayed on the inner peripheral surface of the impregnated body 21. The impregnated body 21 is impregnated. At this time, since the impregnated body 21 is formed in a cylindrical shape and covers the outer periphery of the ejection head 13 over the entire circumference, the ejection head 13 rotates around the holding portion 17 of the mounting cap 14 as an axis. Even if the direction of the nozzle 13c is shifted in the circumferential direction, the volatilizing agent discharged from the discharge head 13 can be reliably sprayed onto the impregnated body 21 to impregnate the impregnated body 21.

  The volatilizing agent impregnated in the impregnated body 21 volatilizes in the air. At this time, since the air blown out from the air blowing port 2 flows around the impregnated body 21 through the vent hole 5b of the back wall portion 5, the volatilizing agent impregnated in the impregnated body 21 is efficiently volatilized by the air flow. Can be made.

  Thus, in the volatilization apparatus 1 of the present invention, the impregnated body 21 is impregnated with the volatilizing agent discharged from the discharge container 11 instead of the volatilizing agent housed in the container body 12 of the discharge container 11, and this impregnated body. Since the volatilizing agent impregnated in 21 is volatilized, only the volatilizing agent discharged from the discharge container 11 can be volatilized. Therefore, even if this volatilization device 1 is left, a larger amount of the volatilizing agent than that discharged from the discharge container 11 is not volatilized, so that a desired amount of the volatilizing agent is discharged from the discharge container 11. Thus, only a desired amount of the volatilizing agent is volatilized, and volatilization of useless volatilizing agent from the volatilization apparatus 1 can be suppressed.

  Further, in the volatilization apparatus 1, an annular groove 20 is provided as a leakage preventing portion on the container body 12 side, that is, the lower side of the nozzle 13 c with respect to the nozzle 13 c of the discharge head 13, and the shaft of the impregnated body 20 is provided in the annular groove 20. Since one end portion in the direction is accommodated, even if an amount of the volatilizing agent that cannot be impregnated into the impregnated body 21 is discharged from the discharge container 11, excess volatilizing agent that cannot be impregnated is removed inside the annular groove 20. Can be prevented from leaking outside. In particular, when a gap is provided between the impregnated body 21 and the annular groove 20, a larger amount of the volatilizing agent is accommodated by the gap, thereby further reliably preventing excess volatilizing agent from leaking to the outside. can do.
