Electrostatic spinning nozzle structure based on capillary principle and application method thereof

The invention provides an electrostatic spinning nozzle structure based on the the capillary principle and an application method thereof. The electrostatic spinning nozzle structure comprises a liquid storage barrel and a flow dividing box installed at the top of the liquid storage barrel, wherein a flow guide cylinder is installed at the top of the flow dividing box; an inserting cylinder penetrating through the upper wall surface and the lower wall surface is arranged in the middle of the flow dividing box; a plurality of air outlet holes are formed in the top surface of the flow dividing box and communicate with the interior of the flow dividing box; an air supply pipe communicates with the side wall of the flow dividing box and is used for communicating with external high-pressure air supply equipment; the bottom of the liquid storage barrel communicates with a liquid supply pipe and a liquid discharge pipe; the pipe diameter of the liquid supply pipe is larger than the pipe diameter of the liquid discharge pipe; a volatilization structure is arranged in the flow guide cylinder; the bottom of the volatilization structure penetrates through the inserting cylinder and extends into the liquid storage barrel; the upper part of the volatilization structure is of a tree-shaped structure; and a plurality of sea urchin-shaped spray heads are installed on branches of the volatilization structure. The structure is novel, a needle-free structure is adopted, the application method is simple, the problem of spray head blockage can be prevented, the diffusion surface of a spinning solution can be effectively increased, and the yield and the quality of spinning fibers are improved.
