Problems solved by technology

[0004] Based on this, it is necessary to solve the problem that the size of the micro-droplets presents randomness due to the unstable and uncontrollable flow rate of the discharged liquid during the movement of the spit nozzle, and provide a method that can ensure that the spit nozzle follows the set flow rate. Fluid drive mechanism and fluid drive method for discharging liquid

Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, a fluid driving mechanism and a fluid driving method of the present invention will be further described in detail through the following embodiments and in conjunction with the accompanying drawings.

[0038] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only. Various objects in the drawings of the embodiments are drawn to a scale conven...

Abstract

The invention relates to a fluid driving mechanism and method for micro-droplet generation system. The fluid driving mechanism comprises a shell, a variable volume component and a linear motor component. The variable volume component comprises an injection tube and a push rod, and the push rod is in sliding fit with the inner wall of the injection tube; driving liquid can be stored in the injection tube, and the injection tube is provided with a liquid inlet and a liquid outlet; and the liquid inlet and the liquid outlet are used for communicating with the inlet end of a drainage gun head storing first liquid. The output end of the linear motor component is in transmission connection with the push rod, and the linear motor component is used for driving the push rod to slide in the extension direction of the injection tube. According to the fluid driving mechanism and method, by taking advantage of incompressibility of the driving liquid and higher motion accuracy of the linear motor component, it is ensured that the first liquid can be still discharged from the outlet end of the drainage gun head during high frequency vibration, so that the size of generated micro-droplets is controlled accurately.

Description

technical field [0001] The invention relates to the technical field of measuring and distributing a small amount of liquid, in particular to a fluid driving mechanism and a fluid driving method. Background technique [0002] At present, there is a wide demand for precise operation of trace liquids in medical clinical testing, nanomaterial preparation, food and environmental testing, biochemical analysis and other application fields. One of the core technologies of micro-liquid manipulation is to further divide microliter-level liquids into micro-reaction systems with nanoliter or even picoliter volumes. A main technical branch of micro-reaction system generation is the generation of emulsified micro-droplets. [0003] In recent years, a variety of microdroplet generation techniques have been reported in the literature, such as membrane emulsification, spray emulsification, microfluidic chip method, spit tip injection / jet method, etc. Among them, the injection / spraying meth...
