Chinese patent (201720057770.9) is a new type of portable electrospinning device. Although the electrospinning device has been improved in portability, the device can only realize the solution electrospinning method, but cannot realize the polymer melt
Because polymer melt needs to be heated and run at high temperature, it means that complex heating system, raw material supply system, heat insulation and insulation system are required, which poses a great challenge to portable design

Abstract
The invention discloses a handheld melt electrostatic spinning preparation device and a method for applying the same. The handheld melt electrostatic spinning preparation device mainly comprises a safety shield, an end cover, fastening screws, a shell, a support plate, a rotary drum, heat preservation cotton, a partition plate, a fan, a resistance heating wire, air holes, air pipes, rollers, a miniature high-voltage electrostatic generator, a wire through hole, an electrode connector, a feed pipe, a needle, exhaust holes, a metal gasket, air pipe holes, a feed pipe hole, a conical hole and thelike. The handheld melt electrostatic spinning preparation device and the method have the advantages that materials can be continuously fed by the aid of wires, heat can be transferred by air heatedby the resistance heating wire, and accordingly the materials can be heated and molten; the needle is connected with high voltages, and electric fields are formed between the needle and grounded receiving plates; hot air can be exhausted from slits between the needle and the conical hole in the end cover after the heat is completely transferred, and accordingly fibers can be secondarily stretched;the handheld melt electrostatic spinning preparation device is simplified, is miniaturized, lightened and portable, accordingly, fibers can be conveniently and quickly prepared, and the handheld meltelectrostatic spinning preparation device can be used for preparing fibers for laboratory application, home use, clinical medical purposes and the aspect of teaching demonstration tools on a small scale.
Description
technical field [0001] The invention relates to a hand-held melt electrospinning preparation device and a use method, belonging to the field of electrospinning. Background technique [0002] At present, the electrospinning method is recognized as the simplest and most efficient method for preparing micro-nano fibers. Compared with other methods, the electrospinning method has the advantages of wide source of raw materials, low spinning cost, and large-scale preparation. Fields such as battery separators and biomedicine have shown great application potential, which has attracted widespread attention from researchers. [0003] Existing research and industrial applications have produced a lot of innovations around electrospinning batch devices, but there are few miniature and small-scale electrospinning devices that are portable, small in size and easy to operate. However, such small devices have great potential in laboratory applications, home use, clinical medical use, and a...
