Abstract
A nebulizing element for liquid substances for coupling to procurement elements, includes at least one membrane with a microperforated area; at least one piezoelectric element connected to an electronic circuit and coupled to the membrane to cause it to vibrate; at least one first and one second support that can be placed on top of one another and create, on their interior a compartment to contain the membrane, the piezoelectric element, and a space of limited dimension for the liquid to be nebulized, created beneath the membrane. The second support has an opening for the nebulized liquid outlet, located in correspondence with the perforated area of the membrane. The nebulizing element also includes at least one collector for the liquid that flows from the porous element to the collector itself by capillary action; at least one capillary opening to allow in the liquid to be nebulized and at least one outlet opening to aid air circulation.
