Electric exhaler for the vaporization of disinfesting insecticide products
First Claim
1. Electric exhaler for the fast vaporization of a disinfesting insecticide active substance having a low vapor pressure, comprising a heating resistance (R) adapted a to reach a surface temperature of at least 400°
- C. and a refill (S) of porous ceramic material impregnated with said active substance, said resistance (R) having the shape of a straight cylinder and said ceramic refill (S) being a cylindrical body whose generating lines are parallel to the axis of the resistance (R) and the cross-section of which has an Ω
-shape, the resistance (R) and the ceramic refill (S) being so mutually positioned that a first central portion of said ceramic refill is in contact with the resistance (R) and partially surrounds the resistance and a second, pheripheral, portion of said ceramic refill has at least one wing projecting from said first portion, to rest the ceramic refill (S) on the structure of the electric exhaler.

Abstract
An electric exhaler for the vaporization of disinfesting insecticide products comprises a heating resistance (R) and a refill of porous ceramic material (S) impregnated with an active substance apt to be evaporated at high temperature. The resistance (R) is apt to reach a surface temperature of at least 500° C. and the ceramic refill (S) is positioned in tight contact therewith. Preferably, the resistance (R) is cylindrical and the refill (S) has a cross-section having a Ω- or C-shape, the curved portion of which has an inner radius corresponding to the outer radius of the resistance

15. Electric exhaler for the vaporization of disinfesting insecticide products, comprising a heating element and a porous support impregnated with an active substance adapted to be evaporated at high temperature, said heating element being a resistance (R) adapted to reach a surface temperature of at least 400°
- C., said support being a refill (S) of porous ceramic material, said resistance (R) being fixed to a central portion of a metallic heat sink (5) having arms (5a, 5b) which are fixed to the structure of the electric exhaler, said arms of the metallic heat sink (5) being fixed to supports (4, 6) projecting from a base (1) or cap (2) of the electric exhaler and formed, in one piece therewith of a heat-resisting plastic material.
