Abstract

The invention relates to a bionic cilium type high-precision nanodrop nozzle device, which belongs to a droplet nozzle device. A polyethylene glycol terephthalate nozzle is installed on the lower part of a bracket, a field coil is installed on the bracket and is located above the polyethylene glycol terephthalate nozzle, a focused ultrasound transducer is installed on the bracket and is located on the field coil, bionic cilia are arranged on the lower inner wall of a main body of the polyethylene glycol terephthalate nozzle, and a liquid storage chamber is arranged above the main body. The bionic cilium type high-precision nanodrop nozzle device has the advantage of novel structure; magnetic powder is controlled to swing by virtue of an alternating magnetic field, so that nanoscale movement of sprayed droplet materials is realized; droplet power is provided by non-contact type focused ultrasound, so that the spray speed is increased, and the droplet spray precision is greatly increased; and the sprayed droplet diameter is less than the diameter of the nozzle, so that the bionic cilium type high-precision nanodrop nozzle device can be used for spraying all low-viscosity droplet materials such as electrochemical electrolyte, cell suspension, low-viscosity photosensitive resin and the like.

Description

technical field [0001] The invention relates to a droplet spraying head device, in particular to a cilium-like high-precision nano-droplet spraying head device. Background technique [0002] Micro-droplet injection technology is a technology in which liquid is ejected from the nozzle in the form of micro-droplets through external force. The volume of the sprayed droplets is very precise, generally up to nanoliters to microliters, or even to picoliters. The technology has the characteristics of high resolution, simple structure, and a wide range of applicable materials. It has a wide application range, strong practicability, and broad application prospects. [0003] The key to the technology of droplet spraying depends on the droplet nozzle. At present, the typical principles of droplet spraying technology include pneumatic, mechanical, thermal bubble, piezoelectric, etc.: [0004] 1) Pneumatic micro-drop nozzles control the compressed gas in the nozzle, and the pressure of ...
