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.

Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail through the following embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] 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 i...

Abstract

The invention relates to a fluid driving mechanism for a microdroplet generation system. The mechanism comprises a variable volume assembly and a power assembly. The variable volume assembly comprisesan injection cylinder and a push rod, wherein the push rod is in sliding fit with the inner wall of the injection cylinder, driving liquid can be stored in the injection cylinder, the injection cylinder is provided with a liquid inlet and a liquid outlet, the liquid inlet and the liquid outlet are used for communicating the inlet end of a liquid ejecting gun head storing first liquid, and the power assembly is in transmission connection with the push rod. In the process of generating the microdroplets, the power assembly drives the push rod to extrude the driving liquid stored in the injection cylinder, and the driving liquid extrudes the first liquid stored in the liquid ejecting gun head, so that the first liquid is discharged from the outlet end of the liquid ejecting gun head. The invention also relates to a fluid driving method adopting the fluid driving mechanism. According to the fluid driving mechanism and the fluid driving method, the incompressibility of the driving liquid is utilized to ensure that the outlet end of the liquid ejecting gun head can still discharge the first liquid from the outlet end of the liquid ejecting gun head according to a set flow rate when theoutlet end of the liquid ejecting gun head vibrates at a high frequency.

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...
