Abstract
A device for controlling evaporation of a liquid has a container and a heating element for heating and evaporating liquid in the container. The container is disposed on a base plate which is supported by a leaf spring which allows the base plate to move between two microswitches depending upon the amount of liquid in the container. The microswitches are connected to a control circuit for activating the heating element and interrupt the flow of power to the heating element when little or no liquid is present in the container, or when a maximum amount of liquid is present in the container.
