INJECTION VALVE DEVICE FOR AEROSOL SPRAY

摘要

The present invention relates to an injection valve device for an aerosol spray, in which an undiluted solution is sprayed through a spray hole to the outside from a pressure container where the undiluted solution and a spray propellant are stored. The injection valve device for the aerosol spray according to an embodiment of the present invention includes: a housing part fixedly installed on a mounting cup connected to an inlet of the pressure container to be disposed within the pressure container; a stem installed to pass through the mounting cup and guiding the undiluted solution and the spray propellant in the pressure container to be introduced into the spray hole through paths isolated from each other; and a cyclone spray shaft installed within a button to be adjacent to the stem and the spray hole, and having s spiral path for guiding the spray propellant so that the spray propellant introduced form the stem is moved into the spray hole.
