With the above-described conventional blowing-type medicine diffusion device, the medicinal component of the suction side medicine and the medicinal ingredient of the discharge side medicine can be diffused into the atmosphere at the same time, so that a plurality of purposes can be achieved at the same time.
However, since all of the air containing the medicinal component of the suction side drug passes through the discharge side drug and is released to the atmosphere, the discharge side drug becomes an obstacle to smooth discharge when the air is released to the atmosphere. The medicinal component of the suction side drug is difficult to be released to the atmosphere, and the released amount is reduced.

In order to solve this problem, in the above-described conventional blowing-type medicine diffusion device, an airflow passage (hole) is provided in the discharge-side medicine, and a part of the air containing the medicinal component of the suction-side medicine is removed from the airflow passage. By directly releasing to the atmosphere and releasing the remaining air to the atmosphere through the discharge side medicine, the medicinal components of the suction side medicine can be easily released to the atmosphere, and the amount of release can be increased.
However, in this case, since the amount of air passing through the ejection side medicine is reduced, the amount of the medicinal component of the ejection side medicine released to the atmosphere is reduced.

  An object of the present invention is to provide a blown medicine diffusion device that can release a large amount of a medicinal component of a suction side drug into the atmosphere and can release a large amount of a medicinal component of a discharge side drug into the atmosphere.
