Abstract
An evaporator is provided, for use with a wicked reservoir containing a volatile liquid. The reservoir has a plurality of guide members disposed symmetrically around the wick and extending beyond the height of the wick. The evaporator features a base containing a battery, and a removable cover containing a heater. Attachment of the cover to the base is necessary to establish an electrical connection between the battery and the heater. The guide members fit into recesses in the cover only when the heater and wick are properly aligned, and the heater cannot make electrical connection with the battery unless the guide members and wick are properly aligned with the recesses and heater, respectively.
