Energy-saving control method of resonant piezoelectric air pump

Abstract

An energy-saving control method of a resonant piezoelectric air pump includes steps of: (a) providing the resonant piezoelectric air pump and a control module, wherein the resonant piezoelectric air pump and the control module are electrically connected to each other; (b) at the beginning of a unit of time, operating the control module to transmit an enable signal to the resonant piezoelectric air pump so that the resonant piezoelectric air pump is driven to transfer an amount of air in a process for air transfer; (c) during the unit of time, adjusting a duty ratio of the enable signal by using the control module for enabling or disabling the resonant piezoelectric air pump; and (d) after spending the unit of time, repeating the step (b) and the step (c) in another unit of time or more units of time thereafter until the process for air transfer is completed.
