The present invention relates to a multipurpose composite deodorizing device comprising: a main capsule body for accommodating an air freshener, a deodorizing agent, or a harmful insect repelling agent and a variable installation member attached to and detached from the main capsule body. The multipurpose composite deodorizing device can have a variable installation and usage relationship according to a demanded purpose without being restricted by any one specified handling (installation) shape, for example, the properties of purposes such as a disposing type, a hanging type, an attaching type, a decorating type, and an accommodating type. By means of the variable installation and usage relationship, a general-purpose, economical, and efficient usage relationship can be ensured without being restricted by the properties of using places such as a bathroom, a shoe rack, a closet, and a bedroom. To this end, the multipurpose composite deodorizing device comprises: a main capsule body including a chemical accommodating spatial part formed on the inner surface thereof by coupling a top cover and a bottom cover, having an installation member connector formed on the top cover to have a protruding structure, and having a chemical emitting hole formed on the front surface of the bottom cover and a variable installation member formed as a variable installation means attached to and detached from the installation member connector, having a capsule connection plate having a coupling inducing hole formed therein, having an installation inducing groove integrally connected with one side surface of the capsule connection plate to have a rectangular shape without a side, and having an assisting friction projection formed on the inner top surface of the installation inducing groove.본 발명은 다용도 복합 탈취기에 관한 것으로, 그 기술구현의 목적은, 방향제, 탈취제, 또는 유해충 퇴치제가 수용되는 메인캡슐 본체와, 그 메인캡슐 본체로 탈/부착되는 가변 설치부재를 형성하여, 특정된 어느 하나의 취급(설치)형태, 예컨대, 거치형, 걸이형, 부착형, 장식용, 수납용 등과 같은 용도별 특성에 구애받음 없이, 필요로 하는 용도에 따라 가변적인 설치
