CA 2702763

The invention refers to a spray pump device for spraying a liquid operated by a memory shape element (11). The spraying device is provided with a memory shape alloy wire (11) 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.

L'invention se rapporte à un dispositif à pompe de pulvérisation destiné à pulvériser un liquide actionné par un élément à mémoire de forme (11). Le dispositif de pulvérisation est pourvu d'un fil en alliage à mémoire de forme (11) à résistivité électrique, capable de générer de la chaleur qui augmente sa température de sorte que, en raison de sa propriété de mémoire de forme, le fil se rétrécisse lorsqu'un courant est appliqué. Ce rétrécissement permet au fil d'activer une pompe qui pulvérise une substance volatile.
