Problems solved by technology

[0004] However, the previous structure cannot respond to changes in external humidity and stably release low-concentration volatile drugs.
When the amount of liquid drug is large at first, the amount of volatilized drug is large, but as the amount of drug decreases over time, the release amount tends to decrease accordingly, so there is a problem that the drug cannot be volatilized or released uniformly

Abstract

There is provided a volatile medicine controlled release member capable of equalizing and controlling volatile release of medicine at a low concentration release speed, preventing unnecessary release by sufficiently dealing with a humidity change, and having a structure wherein a volatile volume is hardly affected even when a liquid volume of the medicine falls. The volatile medicine controlled release member is provided with a container with an interior filled with liquid medicine, a liquid absorber comprising a medium for sucking up the medicine, a space part for filling an interior with the medicine volatilized from the liquid absorber, and a humidity sensitive film with a permeation amount of the medicine changing in response to the humidity change. The medicine is sucked up and volatilized by the liquid absorber, and it is controllably released from the humidity sensitive film in response to the humidity change while it is retained at certain concentration in the space part formed by the liquid absorber and the humidity sensitive film.

Description

technical field [0001] The invention relates to an air conditioner, which is equipped with a slow-release device for volatile medicine, and can be widely used in the field of preventing mold and bacteria from multiplying due to seasonal changes or environmental humidity changes at that time. For example, it is suitable for bathrooms, changing rooms, clog boxes, food refrigerators, warehouses, underground storage warehouses, as well as humidification and ventilation passages for building air conditioners. It is particularly effective in keeping the indoor unit of an air conditioner always in a clean state. Background technique [0002] There are many technologies for long-term sustained release of filling liquids, and the method of impregnating porous materials and slow volatilization through capillary phenomenon is usually adopted. The above-mentioned porous substance is an inorganic compound such as pumice or silica gel, or a polypropylene, polyester, cellulose foam, fiber...
