Liquid atomiser with piezoelectric vibration device having an improved electronic control circuit, and activation method thereof

A liquid atomizer that operates between alternate activation cycles and rest cycles, comprising:

• a piezoelectric vibration device (4);
• a first supply circuit (2) with an impulse current generator (9) for activating said piezoelectric vibration device (4) with a relatively high voltage during the activation cycles;
• a second supply circuit (5a) for supplying energy to the piezoelectric vibration device (4) at a relatively low voltage;
• and
• a switch device (10, 11) that connects in alternate phases the piezoelectric vibration device (4) to one of said first circuit or said second circuit in order to alternately supply energy to the piezoelectric vibration device (4) through said first or said second circuit within a same activation cycle,
• wherein said second supply circuit (5a) consists of a direct connection to a power source (1).
