PROBLEM TO BE SOLVED: To provide a heat-transpiring device in which a liquid container can be attached to or detached from the device easily, and which can prevent the liquid container from falling unexpectedly.SOLUTION: A heat-transpiring device 10 includes a bottle stopper 250 that holds a liquid container 300 having a liquid-absorbing core 301 in which liquid is put, and which is disposed protruding from inside the container to outside the container, and is immersed in the liquid in the container. The heat-transpiring device 10 includes a heating unit 103 for heating the liquid-absorbing core 301 and transpiring liquid from the liquid-absorbing core, and further includes a holder 200 for approximating or separating the liquid-absorbing core 301 of the liquid container 300 and the heating unit 103.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】液体容器の装置への装着・取り外しが容易で、且つ、液体容器の不意の落下を防ぐことができる加熱蒸散装置を提供する。【解決手段】加熱蒸散装置10は、液体が充填され容器内から容器外へ突出して設けられ、且つ、容器内において液体に浸漬される吸液芯301を有する液体容器300を保持するボトルストッパ250を有する。また、加熱蒸散装置10は、吸液芯301を加熱し、この吸液芯から液体を蒸散させるための加熱部103を有する。さらに、液体容器300の吸液芯301と加熱部103とを近接、又は、離間させるホルダ200を有する。【選択図】図1
