The Ultrasonic Atomizer is an intelligent ultrasonic atomization device which integrates the atomizing transducer and circuit board. Compared to the traditional atomizer which has separate circuit and transducer, it features compact size, low power consumption and low heat. Unlike the traditional one with analog signal control, it is controlled by digital signal, thereby facilitating the development of extensional functions such as APP control, bluetooth connection, controlled lighting, etc to intelligentize the whole device.
