Fluid trace jetting device

Abstract

The embodiment of the invention discloses a fluid trace jetting device. The fluid trace jetting device comprises an execution system, a flow passage assembly and a movable unit arranged between a basebody and a fluid seat; the execution system comprises the base body and an execution mechanism, an execution mechanism installing cavity is defined in the base body, and the execution mechanism is movably arranged in the execution mechanism installing cavity; the flow passage assembly comprises the fluid seat, a jet nozzle and a fluid feeding joint, a fluid cavity, a flow passage and an installing cavity are defined in the fluid seat, the base body is arranged on the fluid seat, the jet nozzle communicates with the fluid cavity, and the fluid feeding joint communicates with the flow passage and provides fluid for the jet nozzle through the flow passage and the fluid cavity; the movable unit comprises a movable element and a first elastic component, when assembling of the execution systemand the flow passage assembly is carried out, the upper end of the movable element is connected with the execution mechanism of the execution system and controlled by the execution mechanism, the lower end of the movable element matches with the jet nozzle to open and close the jet nozzle, the two ends of the first elastic component abut against the upper end of a guide seat and the upper end of the movable element correspondingly. The fluid trace jetting device is convenient to use and clean, and adjustments of the fluid jet effect are accurate.

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...

Problems solved by technology

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

In addition, the fluid flow path of the existing fluid micro-injection device has a closed flow path, which is cumbersome to clean, and the installation and disassembly of related accessories is cumbersome, resulting in low assembly efficiency, inconvenient installation, disassembly, and cleaning, high maintenance costs, and time-consuming assembly.
