Fluid micro-spraying device and executing system thereof

Abstract

The invention discloses an executing system of a fluid micro-spraying device, and the fluid micro-spraying device with the executing system. The executing system comprises a base body, a movable element, an executing mechanism an adjusting element and a plurality of spacer shims, wherein an executing mechanism installation cavity is limited in the base body; a positioning hole communicating with the executing mechanism installation cavity is formed in the base body; the movable element can be movably arranged in the positioning hole; the executing mechanism can be movably arranged in the executing mechanism installation cavity, and is connected with the movable element so as to control the movable element to move; the adjusting element is arranged in the executing mechanism installation cavity and is connected with the executing mechanism so as to adjust a working position of the executing mechanism; the spacer shims are arranged between an inner wall surface of the executing mechanism installation cavity and the adjusting element so as to adjust a pre-tightening force of the executing mechanism. According to the executing system of the fluid micro-spraying device provided by the embodiment of the invention, the pre-tightening force of the executing mechanism can be adjusted, so that the movable displacement of the movable element is adjusted so as to adjust a fluid spraying effect of the fluid micro-spraying device.

Description

technical field [0001] The invention relates to an execution system of a fluid micro-injection device and a fluid micro-injection device with the same. 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.
