The invention refers to a spray pump device for spraying a liquid operated by a memory shape element. The spraying device is provided with a memory shape alloy wire with electrical resistivity, that is able to generate heat that increases its temperature so that due to memory shape property, the wire shrinks when current is applied. This shrinking permits the wire to activate a pump that atomizes a volatile substance.

Spray pump device

A liquid atomizer () with battery-powered () piezoelectric vibration device (), of the type timed to occur between alternate activation cycles and rest cycles and including a first electronic supply circuit () with an impulse current generator () at a relatively high voltage and a second supply circuit () of the piezoelectric vibration device () at a relatively low voltage, as well as a switch device () apt to connect in alternate phases the supply of the piezoelectric vibration device ()&#x2014;in a same actuation cycle&#x2014;to the first circuit and to the second circuit. An actuation method of the atomizer is also described.
