Abstract:
Evaporator for volatile products wit vapour evaporation rate controlled by means of an interposed moving cap, applicable to the evaporation of insecticides, perfumes or similar, comprising:a case which forms a plug for electrical power supply, said case having an exit orifice,a heater disposed in said case, said heater baying a heater orifice and an area of influence,a replaceable container for storage of a volatile product and having a wick through which a volatile product rises to reach said area of influence of said heater,and a movable cap interposed between said wick and said heater, said cap being axially movable between said wick and said heater orifice,wherein the regulation of the degree of vapour evaporation is performed by said movable cap, such that said cap defines a conduct for the vapour generated to rise, causing a chimney effect which favours evaporation as it accelerates the upwards flow of the vapour, regulation being obtained by the different positions of said movable cap, so that the rising path of the vapour is completed to a lesser or greater degree until it leaves through said exit orifice, while simultaneously a more efficient evaporation is obtained, and in flat the interposition of said movable cap between said wick and said heater distances the extremes of evaporation, to allow a greater capacity of regulation.
