The multi-head for ejecting liquid droplets, burning devices containing such HEAD AND METHOD FOR RELEASE of liquid droplets from said head

摘要

FIELD: physics.;SUBSTANCE: invention relates to methods of electing fluid drops. Proposed portable gadget comprises cylindrical casing with a hole at its front that accommodate fluid reservoir, accumulator, control unit and fluid drop ejection head. It includes also multiple actuator chambers with inlet communicated with aforesaid fluid reservoir, actuator to generate pulsations in fluid by power supplied by control unit, and outlet communicated with nozzle. Multiple nozzles are arranged along the radius and equidistant from central axis (X) to make ejected drops combine at preset point located at a distance from aforesaid head. Note that every nozzle features ejection axis and is arranged so that nozzle ejection axes intersect at said preset point. Multiple actuator chambers are arranged radially about central axis, while said preset point is located on central axis (X) and nozzle are directed outward from front hole of cylindrical casing. Proposed method comprises feeding fluid into actuator chambers via inlets and switching on actuator devices and chambers.;EFFECT: fluid drops ejection from great distance onto substrate.;16 cl, 5 dwg
