An Ultrasonic Stepping Ultrafine Single Mist Droplet Generator

Abstract

The invention provides an ultrasonic stepping ultra-fine single mist generator, which consists of a valve body, a valve core and a spring to form a one-way valve. The inverse piezoelectric effect of the electroceramic drives the catheter to move linearly, and the liquid in the spray chamber is squeezed out of the nozzle by using the nanoscale feed of the ultrasonic linear motor to obtain tiny and quantitative droplets. Since the catheter driven by the piezoelectric vibrator can generate nanoscale feeding, the volume of each spilled droplet can reach the micron level, which meets the requirements for generating tiny droplets.

Description

Technical field [0001] The present invention relates to an ultrachonial step-in superfine plum droplet generator belonging to the field of agricultural engineering. Background technique [0002] In agricultural engineering disciplines, tiny monoliths are very important for crop nutrient absorption quantitative analysis. At present, the microfluidic field is mainly used in microfluidic chips. Most of this chip is extremely high due to the requirements of processing accuracy, resulting in high processing costs and cannot be done. Another technique for producing a small liquid is applied to the inkjet printer, typically hot foaming techniques or piezoelectric techniques, which are mostly structurally complicated and insufficient enough, and require complex control systems. [0003] At present, there is a problem that the equipment in which tiny monolic droplets is widely prevail, the structure is complex, and the cost is too high. Inventive content [0004] In response to the prior...
