Abstract

The electrical heater is intended esp. for evaporating liquids and solids such as perfume or insect repellent, etc. The heater is in three basic parts, an element wound on a cylindrical isolator, a 'T' shaped receptacle (16) and an outer cover with an integral power supply plug (20). The receptacle has a central hole in the leg of the 'T' this has two longitudinal grooves (12) to allow alignment of the element cylinder and two slots (14) breaking through the wall of the 'T' taking the wiring of the element. The material to be evaporated is laid on the flat top of the 'T'.
