The container 2 for storing liquid is communicated with a water inlet 16 of the anti-static miniature high-pressure pump, a water outlet 17 of the anti-static miniature high-pressure pump is connected with the needle tube 2, the needle tube 3 is connected with the spray head 4 through an insulating hose, and the spray head 4 is connected with a high-voltage power supply through an insulating lead 10.
High voltage is applied to the spray head 4 and the liquid to be sprayed through a high-voltage power supply, and the liquid to be sprayed sprays nano-diameter filaments from the spray head 4, and the filaments are attached to the surface of human skin or other objects and are condensed into a fiber film structure. The anti-static miniature high-pressure pump 6 can push and convey liquid to be sprayed. As illustrated in fig. 1.
The electrostatic spinning is a manufacturing process of the nano-fiber. The solution or melt of high molecular polymer is charged positively or negatively in high voltage environment, under the action of high potential difference, the liquid drop at the needle head can be changed into cone from spherical shape, i.e. taylor cone, and the fiber filament can be obtained by spraying and spreading from the tip of cone, and its surface is in the form of fog, and its polymer is in the form of micro jet flow. Can travel a considerable distance in air to reach the skin of a human body or other receptor, and the fiber is solidified into nanometer-scale diameter fiber which is deposited on the surface of the skin or other objects. The diameter of the nano fiber can reach below 100 nanometers. Electrostatic spinning has become one of the main approaches for effectively preparing nanofiber materials due to the advantages of simple manufacturing device, low spinning cost, relatively high production efficiency, simple operation, controllable process, wide application range and the like.
The shell 11 of the device is made of insulating materials, and the spray head 4 is provided with an insulating sleeve. The insulating material is formed by mixing an inorganic insulating material and an organic insulating material, wherein the inorganic insulating material is mica, asbestos, sulfur and the like, and the organic insulating material is shellac, resin, rubber and the like. Preferably, the resistivity of the insulating material is larger than 1010 omega-m, and the compressive strength is larger than 50 KV.
The spray head 4 is a syringe needle and an object with a tiny hollow pointed shape, and is made of conductive metal and other materials. The diameter of the micro hollow cross section of the spray head 4 is below 2000 mu m. The outer layer of the spray head 4 is wrapped by an insulating sleeve, and the insulating sleeve is also made of the insulating material of the shell 11. Preferably, the spray head is located in a recess in the upper portion of the housing 11, and has a shape as illustrated in fig. 2.
The anti-static miniature high-pressure pump 6 is characterized in that the anti-static effect is achieved by adding carbon black, carbon fiber and other conductive substances or an anti-static agent into a material for manufacturing a shell of the high-pressure pump. Preferably, the pressure maximum value of the micro high-pressure water pump is more than 5 kilograms, the flow is more than 1 liter per minute, the suction lift is more than 1 meter, the noise is lower than 50 decibels, and the micro high-pressure water pump has a stable self-suction function without adding water firstly. The anti-static miniature high-pressure pump 6 is schematically shown in fig. 3.
The injection speed of the anti-static miniature high-pressure pump 6 is set by three-five-gear parameters to realize injection at different speeds, and is set by a control panel 7. Meanwhile, the control panel 7 can also perform parameter setting such as injection time. The control panel is provided with control buttons 18 for injection speed, injection time, power switch, etc.

Can be sprayed on the human skin or other various complex object surfaces which are not easily covered in a normal mode, thereby enhancing the covering effect of the nanofiber membrane. Specifically, the spray head position and angle adjuster 5 is a thin sheet with a hollow center and a thickness of 1mm-20mm, a part extending outwards from the center is exposed outside the shell 11, and two ends of the part are clamped in linear clamping grooves of the shell. Furthermore, the part with the hollowed-out outer center is sleeved on the needle head. As illustrated in fig. 4. When a force perpendicular to the shell is applied to the exposed part, the needle head can be driven to move in the direction perpendicular to the shell through the spray head position and angle adjuster 5, and the moving range of the needle head is determined by the length of the linear clamping groove on the shell 11; when a force parallel to the housing is applied to the exposed portion, the injection angle of the needle can be adjusted by the position and angle adjuster 5 of the nozzle head within an adjustment angle range of-30 degrees to 30 degrees. The nozzle position and angle adjuster 5 is also made of an insulating material, and preferably has a compressive strength of more than 50 KV.
The nozzle 4 is connected with the needle tube 3 through the hose 9, and the rear handle of the needle tube is replaced by the miniature high-pressure pump, so that the placing freedom of each part is increased, the size of the handheld device is reduced, and the design freedom is increased.
