Single-particle high-speed drop generator

Abstract

The invention relates to a single-particle high-speed drop generator and belongs to the field of instruments and meters. In the invention, a buffer gas water storehouse is connected to a drop generator by virtue of a liquid pipe; a liquid outlet is arranged at the bottom centre of a liquid storage storehouse of the drop generator; liquid guide channels are arranged on the centre axes of an annular piezoelectric ceramic chip, an annular insulation gasket and a conical amplitude transformer below the liquid storage storehouse; a deflection electric field board I is symmetrically arranged below a charged ring in a drop parameter adjusting device; and a liquid collecting slot is arranged below the deflection electric field board I. The single-particle high-speed drop generator related by the invention can be used for precisely determining various parameters, and generating the needed drops stably and continuously. An electron gun is arranged below the liquid collecting slot; two annular accelerating electric field boards are arranged below the electron gun, so that the drops have a desired initial speed; and a deflection electric field board II is arranged below the annular accelerating electric field boards, so that the deflection direction required by the drops can be achieved. The device has the characteristics of safe electric signals, extreme low energy consumption, simplicity in operation and convenience for use.

Description

Technical field: [0001] The invention relates to a single-particle high-speed droplet generating device, which belongs to the field of instruments and meters. Background technique: [0002] At present, the particle size of the droplets produced by the droplet generating device is uneven and large. With the development of science and technology and the needs of scientific experimental research, more and more scientific experiments and social production require micron-sized single particles, and Droplets with a high initial velocity and a certain ejection direction. However, the existing devices cannot accurately produce small-sized droplets, nor can the droplets have a high initial velocity and an accurate injection direction, let alone continuously produce droplets with the same parameters. Invention content: [0003] The object of the present invention is to provide a kind of micron particle size that can continuously produce the same parameter, have the liquid droplet o...
