Fluid trace jetting device

Abstract

The invention discloses a fluid trace jetting device. The fluid trace jetting device comprises an execution system and a flow channel assembly; the execution system comprises a base body, a movable element, an execution mechanism, an adjusting element and a plurality of gap sheets, wherein an execution mechanism installing cavity is defined in the base body, a positioning hole communicating with the execution mechanism installing cavity is formed in the base body, the movable element is movably arranged in the positioning hole, the execution mechanism is movably arranged in the execution mechanism installing cavity and is connected to the movable element to control the movable element to move, the adjusting element is arranged in the execution mechanism installing cavity and is connected to the execution mechanism so as to adjust the working position of the execution mechanism, and the multiple gap sheets are arranged between the inner wall surface of the execution mechanism installing cavity and the adjusting element so as to adjust the pre-tightening force of the execution mechanism; and the flow channel assembly is connected to the execution system and comprises a fluid base, a nozzle and a fluid supply connector, wherein the base body is arranged on the fluid base, and the fluid supply connector communicates with a flow channel so as to pass through the flow channel and a fluid cavity to supply fluid to the nozzle.

Description

technical field [0001] The invention relates to a fluid micro-injection device. Background technique [0002] The existing fluid micro-injection device adopts a flexible hinge mechanism or an operating element to drive the secondary movement of the closing element through a lever, so as to realize fluid micro-injection. The secondary movement causes wear on both ends of the closing element, increasing the frequency of replacement and increasing the maintenance cost; the lifting height of the closing element cannot be adjusted or the adjustment accuracy is not high, resulting in the impact force required for fluid injection being unadjustable or inaccurate, resulting in fluid injection The effect does not meet the requirements; the installation and disassembly of related accessories is cumbersome, resulting in low assembly efficiency and inconvenient maintenance and replacement. Moreover, the fluid channel of the existing fluid micro-injection device has a closed channel, wh...
