Electronic cigarette liquid supply device and method

摘要

An electronic cigarette liquid supply device includes the piezoelectric substrate, the insulating film, the first interdigital transducer, the second interdigital transducer, the liquid storage chamber, the flow channel and the liquid outlet. A liquid inlet is provided on the liquid storage chamber. One end of the flow channel is hermetically connected to the liquid storage chamber, and the other end of the flow channel is the liquid outlet. The first interdigital transducer and the second interdigital transducer are attached to a surface of the piezoelectric substrate and located between the piezoelectric substrate and the insulating film. The liquid storage chamber, the flow channel and the liquid outlet are provided outside and above the insulating film.
