Embodiment Construction
[0027] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0028] According to the formula (1), once the liquid is determined, the surface tension coefficient and density of the liquid are constant. If it is necessary to prepare finer (that is, smaller diameter) droplets, the frequency of the ultrasonic wave must be increased, but limited by piezoelectric ceramics, rare earth Or the physical size of other magnetostrictive materials, cannot increase the frequency of sound waves without limit. Therefore, for a certain liquid, the size of the atomized particles must have a limit area; at the same time, due to the limitation of physical size, the power of a single ultrasonic device is limited, which also limits the size of the a...
