The experimental result shows that the natural or resonant frequency of the sample of the PZT-4(2-1/2/3/4) of the comparison example is too high (up to several or dozens or hundreds of MHz, the thinner and the higher the power is), the power exceeds 6W, and the common driving circuit board is difficult to drive the sample to vibrate, so that the atomization is difficult.
The experimental results show that the sample of PZT-4(2-1/2/3/4) of the comparative example consumes much more energy than the examples and is not suitable for miniaturized devices.
From the experimental results, it can be seen that the atomization performance of the examples PZT-5(1-1/2/3/4) and the comparative examples (1-1) is reduced with the increase of the natural or resonant frequency when the pore diameter, the number and the perforated area of the atomization microporous region are substantially the same, but the atomization performance of the examples is still good and within the acceptable range.
According to the experimental result, the size of the piezoelectric ceramic (PZT-5) sheet is reduced, and the electronic cigarette endurance time is prolonged.
From the experimental results, the inherent or resonant frequency of the piezoelectric ceramic (PZT-5) sheet is reduced, and the size of the piezoelectric ceramic sheet is increased, which is not beneficial to the miniaturization of the electronic cigarette; further, as the size increases, the vibration power consumption increases, so too low a natural or resonant frequency is not suitable for miniaturizing the electronic cigarette device.
From experimental results, the inherent or resonant frequency of the piezoelectric ceramic (PZT-5) sheet is increased, the size thereof is reduced, and the area of the through hole is correspondingly reduced, so that the number of atomization working areas or atomization micropores capable of being perforated is correspondingly reduced, which may reduce atomization efficiency;
furthermore, the more the natural or resonant frequency of the piezoelectric ceramic (PZT-5) sheet increases, the more it deviates from the natural or resonant frequency of water (42khz), the lower the atomization efficiency; therefore, the piezoelectric ceramic sheet having an excessively high natural or resonant frequency, for example, higher than 300khz, loses or greatly lowers the practicability, and is not suitable for a miniaturized electronic cigarette device.
In summary, under the condition of acceptable atomization performance, the ultrasonic atomization (PZT-5) sheet according to the present invention can meet the specific sequence requirements of a miniaturized electronic cigarette device: the size can be reduced as much as possible, the endurance time can be prolonged, and the compliance can be increased as much as possible, so that the device is convenient to use.
