Since they are arranged, when the outer shell pieces 11 and 12 are pulled, the columnar member 60 on the small diameter side, which is housed in the columnar member 60 on the large diameter side, is pulled out, and the entire length of the connecting member 5 is extended.

And when the full length of the connection member 5 becomes the maximum length, the inner side flange 62 and the outer side flange 63 of each columnar member 60 contact | abut, and the expansion | extension of the connection member 5 stops.
The state at this time is as shown in FIGS. 2, 3, and 7. A large gap is formed between the outer shell piece 11 on the lower side and the outer shell piece 12 on the upper side, and the above-described substantially sealed space 19 is opened to the outside. It becomes a state.
Moreover, since the moderate friction force arises by the friction member 66 and the connection member 5 can maintain the full length of the connection member 5 by the said friction force in arbitrary length, the main body member 2 can be made independent.
The drug diffusing apparatus 1 may be installed by placing the main body member 2 directly on the floor surface using a self-supporting function or by hanging it on a wall or the like using the hanging member 10.

Further, both ends of the medicine holding member 6 and the protection member 7 are attached to the lower outer shell piece 11 and the upper outer shell piece 12 via a net attachment ring 35 and a protection member attachment ring 36, respectively. When the outer shell piece 11 on the lower side and the outer shell piece 12 on the upper side are separated from each other, the drug holding member 6 and the protective member 7 are expanded and spread.
The indicator main body 71 projects from the case member 70 of the indicator 14.
The state at this time is as shown in FIGS. 2 and 3. There is a drug holding member 6 in a state of being expanded in a cylindrical shape surrounding the extended connecting member 5, and further being expanded in a cylindrical shape around the drug holding member 6. There is a protective member 7 in a heated state.

In many cases, the drug diffusing device 1 is installed indoors. However, since the drug holding member 6 is in direct contact with the outside air and the drug holding member 6 is in a net shape, there are many opportunities for contact between the outside air and the drug. Therefore, the medicine held by the medicine holding member 6 is vaporized or sublimated and is diffused into the atmosphere.
Further, in the present embodiment, since a net-like member is used for the drug holding member 6 and the protection member 7, when air blown by a fan or a cooler or natural wind hits the drug diffusion device 1, the wind is a hole in the net. Pass through. That is, since the medicine holding member 6 and the protection member 7 are net-like, when the wind hits them, they pass through almost no resistance and can efficiently diffuse the medicine. Therefore, it is easy to diffuse the medicine in the medicine holding member 6.

In particular, in the present embodiment, the medicine holding member 6 has a cylindrical shape and is mounted so as to surround the columnar connecting member 5, so that ventilation from any direction passes. That is, the medicine holding member 6 of this embodiment has no directivity with respect to the wind direction.
Even when the drug diffusion device 1 is accidentally touched, the drug holding member 6 is covered with the protective member 7, so that the skin does not directly touch the drug. That is, since the protection member 7 is made of a material that does not soak in the medicine, the medicine is not attached even if the protection member 7 is touched.
Thus, in this embodiment, although the device which makes it difficult to touch the chemical | medical agent holding member 6 with the protective member 7 is made | formed, the protective member 7 does not become the obstacle of spreading | diffusion of a chemical | medical agent.

  When the insect repellent is temporarily stopped before the medicine in the medicine holding member 6 is completely volatilized, the main body member 2 can be sealed to prevent the medicine from being diffused until it is used again. As described above, in the drug diffusing device 1 of the present embodiment, the drug can be diffused only when necessary, so that the drug is not wasted.

When the main body member 2 is contracted, it is desirable to bring the outer shell pieces 12 and 11 close to each other while relatively rotating the upper outer shell piece 12 and the lower outer shell piece 11. That is, when the upper outer shell piece 12 and the lower outer shell piece 11 are moved straight, the drug holding member 6 and the protective member 7 located in the middle spread sideways and are surrounded by the outer shell pieces 11 and 12. Stick out. Therefore, the medicine holding member 6 or the like is sandwiched between the outer shell piece 12 on the upper side and the outer shell piece 11 on the lower side, so that the medicine holding member 6 or the like is not fit.
On the other hand, when the distance between the upper outer shell piece 12 and the lower outer shell piece 11 is relatively rotated while the distance between the two is shortened, the drug holding member 6 and the like are wound around the central connecting member 5 to the outside. Spreading is prevented. Therefore, the medicine holding member 6 and the like can be well accommodated.

  In the present embodiment, in order to reduce the distance between the outer shell pieces 11 and 12 while relatively rotating the outer shell pieces 11 and 12, it is necessary to compress the two outer shell pieces 11 and 12 while twisting them. , 12 may be provided to guide the outer shell pieces 11, 12 to rotate forcibly. For example, as shown in FIG. 10, a configuration is possible in which a spiral guide groove 64 is provided on the inner surface of the columnar member 60 and a protrusion 69 provided on the outer periphery of the columnar member 60 is fitted to the guide groove 64.

In the medicine diffusing device 1 according to the above-described embodiment, the connecting member 5 using the nested structure is illustrated, but the structure of the connecting member 5 is not limited to the previous embodiment, and the outer shell piece 11 on the lower side. As long as it is fixed to the outer shell piece 12 on the upper side and the open state and the sealed state of the main body member 2 can be selected by expansion and contraction or the like, any structure may be used.
Next, the structure which employ | adopts the connection member using a spring as other embodiment of this invention is demonstrated.
