Description

technical field [0001] The invention relates to the field of piezoelectric ceramics, in particular to a piezoelectric ceramic applied to electronic betel nuts and a manufacturing method thereof. Background technique [0002] Electronic betel nut is a new consumer product that uses ultrasonic atomization technology to atomize betel nut mixture. Due to the new technology of ultrasonic atomization, it can better restore the taste of betel nut and is healthier. The betel nut mixture is mainly composed of betel nut extract and alcohol mixture. The betel nut mixture is dispersed into micron-sized particles by ultrasonic atomization technology to achieve atomization. [0003] The current electronic betel nut technology has the following problems: [0004] (1) Most of the substances that make up the betel nut mixture are high-molecular substances, which increases the difficulty of atomization, and puts forward higher requirements for the conversion rate of piezoelectric ceramic ato...
