Remote spray handheld electrostatic spinning spray gun

Abstract

The invention discloses a remote spray handheld electrostatic spinning spray gun which comprises a handheld portion and a power portion. The handheld portion comprises a handheld insulating shell, a syringe cylinder is arranged inside the handheld insulating shell, a micro-propulsion pump is mounted at one end of the syringe cylinder, a lengthened sprayer component is mounted on a needle bed at the other end of the syringe cylinder, and the micro-propulsion pump is connected with a propulsion pump controller and a switch through leads. The power portion comprises a high-voltage power supply, apropulsion pump controller power supply and a grounding flat plate, a negative electrode of the high-voltage power supply is connected with the grounding flat plate through a lead, and the propulsionpump controller power supply is connected with the propulsion pump controller through a lead. A sprayer of the electrostatic spinning spray gun is of a handheld structure, spinning positions and spinning distances are conveniently and flexibly adjusted, the sprayer component with a special structure can directly stretch into a recessed structure, a nanofiber membrane can be directly sprayed intothe deep structure, and the electrostatic spinning spray gun has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of electrostatic spinning, in particular to a handheld electrostatic spinning spray gun for long-distance spraying. Background technique [0002] Electrospinning is one of the simplest and most efficient methods for preparing one-dimensional micro-nano fibers. Compared with traditional nanomaterials preparation technology, it has the advantages of simple processing equipment, wide source of raw materials, low spinning cost, and large-scale preparation. In recent years, To receive extensive research reports at home and abroad. Micro-nano fibers processed by electrospinning technology have excellent characteristics such as high specific surface area, large length / diameter ratio, and unique physical and chemical properties. It shows great application potential in other fields. The principle of the electrospinning method is very simple. It is briefly described as follows: under the action of a high-voltage ele...

Problems solved by technology

However, in the actual application process, ordinary electrospinning equipment has limitations such as large volume, large mass, difficult to carry, non-directional fiber deposition, etc., which seriously restricts the popularization and application of electrospinning technology, and the spinning nozzles mostly use conventional nozzles such as syringes Needles, etc., due to the limitation of the structure of the nozzle, cannot penetrate into the structure with a certain depth, so that the nanofiber film can be directly sprayed inside the structure with depth, which limits the scope of use of the device
