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.

FIELD OF THE INVENTION[0001]The present disclosure relates to an energy-saving control method of a resonant piezoelectric air pump, and more particularly to an energy-saving control method for driving a resonant piezoelectric air pump by adjusting a duty ratio.BACKGROUND OF THE INVENTION[0002]With the development of science and technology, air transfer is widely applied in all kinds of electronic devices and medical equipments, and various effects can be achieved by the air transfer. In addition, with the miniaturization and thinning tendency of electronic device and medical equipment, the resonant piezoelectric air pump or the miniature motor is used more widely because of its small size.[0003]In the prior art, the resonant piezoelectric air pump or the miniature motor is driven to transfer the air in an operation without interruption, so as to maximize the amount of the transferred air per unit of time. However, the operation without interruption consumes a lot of power, and the c...

Problems solved by technology

However, the operation without interruption consumes a lot of power, and the consumed power under the operation without interruption can't result in the most efficient air transfer.

Moreover, during the uninterrupted operation of the resonant piezoelectric air pump or the miniature motor,
