Problems solved by technology
The hydrodynamic ultrasonic atomizer uses steam or compressed air as the power source, and uses the ultrasonic vibration generated by the high-speed airflow to atomize the liquid. The cost of atomization is low, but the sound intensity generated by the existing atomizers of this type is generally low. More than 140dB, and requires a higher pressure fluid power source, the energy conversion rate is low, and its atomization ability needs to be further improved

Description
technical field [0001] The invention relates to an atomizing device, in particular to a device for atomizing liquid by using ultrasonic vibration. Background technique [0002] Ultrasonic atomizer is a device that uses ultrasonic vibration to atomize liquid. According to the ultrasonic generation method, it can be roughly divided into two types: hydrodynamic type and electromagnetic conversion type. The electromagnetic conversion ultrasonic atomizer uses an electromagnetic oscillator to convert the electromagnetic oscillation energy of the high-frequency power supply into ultrasonic waves of the same frequency, so the atomization effect of the liquid is better, but the cost is higher due to the need for external electrical equipment. The hydrodynamic ultrasonic atomizer uses steam or compressed air as the power source, and uses the ultrasonic vibration generated by the high-speed airflow to atomize the liquid. The atomization cost is low, but the sound intensity generated b...
