Abstract

A device is disclosed meant to perform evaporation of insecticides, perfumes or the like, wherein the degree of evaporation is controlled by a moving cap (9) which makes up the regulating element (6), which is meant to produce a chimney effect in the upwards motion of the generated vapor, so that this effect enhances evaporation, while regulation is achieved by the different heights at which moving cap (9) can be placed. This displacement is performed manually by moving guide (13) inside inclined track (10).

Claims

1. 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.

2. Evaporator as in claim 1,

wherein said case further comprises a front wall having a track defined by a plurality of inclined ramps, said track being closed by an inner wall, and

wherein said evaporator further comprises a regulating element to which said movable cap is connected, said regulating element further comprising an arm having an upper end and a guide having an inclined upper edge and an inclined lower edge, said movable cap being connected to said upper end of said arm and said guide being connected to the other end of said arm, said guide being positionable within said track, and

wherein the regulation of the rate of vapour evaporation is controlled by the displacement of said glide within said track, which guide rises or falls on said inclined ramps and which displacement of said guide causes, through said arm, the positioning of said movable cap.

3. Evaporator as in claim 1, wherein said case further comprises a graded scale for identifying several positions of said movable cap, and therefore several evaporation rates.

4. Evaporator as in claim 2, wherein said case further comprises a graded scale for identifying several positions of said guide, and therefore several evaporation rates.

5. Evaporator as in claim 2,

wherein said case further comprises an inside having an annular wall, and

wherein said regulating element further comprises a lowermost position and an uppermost position and battlements disposed on said upper end of said arm, and wherein said uppermost position is determined by the contact of said battlements with said inside of said case and wherein said lowermost position is determined by the contact between said am and said heater, and

wherein said uppermost and lowermost positions of said regulating element are also determined by the position of said guide within said track.

6. Evaporator as in claim 2, wherein said regulator element is plastic.
