Abstract

The invention provides a drive circuit applicable to a piezoelectric actuating pump. The piezoelectric actuating pump is provided with a piezoelectric actuator. The drive circuit is provided with a boosted circuit unit and a boosted propelling integrated circuit. The boosted circuit unit at least comprises a plurality of capacitors, a plurality of resistors and a boosted integrated circuit chip which is connected with the plurality of capacitors and the plurality of resistors. The boosted propelling integrated circuit is used for boosting voltage values of input voltage and converting polarity of the input voltage. Therefore, the output voltage is produced to drive the piezoelectric actuator so as to convert electric energy to mechanical energy.

Description

technical field [0001] The present invention relates to a driving circuit, in particular to a driving circuit suitable for piezoelectric actuation pumps and capable of converting electrical energy into mechanical energy and the applicable piezoelectric actuation pumps. Background technique [0002] A typical inkjet printer includes a piezo-actuated pump to eject ink droplets via its periodic high-speed motion. Piezoelectrically actuated pumps usually require a high-voltage AC voltage to act on them to drive the piezoelectric actuator to perform periodic high-speed motion. Using high-voltage AC voltage to drive the piezoelectric actuator, the piezoelectric actuator can output periodic control signals to the single-hole inkjet or porous inkjet vibrating piece to drive the single-hole inkjet vibrating piece or porous inkjet vibration The sheet undergoes periodic motion whereby ink droplets are ejected through a single or multi-hole nozzle of an inkjet printer. Therefore, piez...
