  Furthermore, since the insertion hole is in the vicinity of the heating part, it is possible to more reliably avoid contact of the liquid absorption core with the heating part.

  Furthermore, in the diffuser according to claim 3, since the insertion hole through which the suction core of the drug container is inserted is configured by an elliptical opening, the suction core inserted through the insertion hole is used as the short axis of the insertion hole. The movement in the short axis direction can be restricted by contacting the opening edge located in the direction. Further, when the suction core inserted through the insertion hole tries to move in the major axis direction from the center of the insertion hole, the suction core contacts the opening edge located in the minor axis direction of the insertion hole, thereby The movement of the suction core in the long axis direction can be restricted.

  For this reason, the suction core can be prevented from moving in the short axis direction and the long axis direction in the insertion hole, and the suction core can be positioned at the center of the insertion hole.

  And in the state in which the said suction core was positioned in the center part of the said insertion hole, an empty space can be ensured in the said long-axis direction side part of the said suction core.

  For this reason, the flow of air generated by the heat of the heating unit can be convected from the lower side to the upper side through the empty space, and the diffusion efficiency of the medicine transpiration from the suction core can be increased. .

  Then, by setting the length of the short axis of the insertion hole formed in an elliptical shape to be shorter than the diameter of the heating part, the suction core positioned in the insertion hole interferes with the heating part. Can be reliably prevented.
