no. 1 approach

[0026] The first embodiment of the present invention relates to an electrostatic spraying device, the structure of which is as attached figure 1 As shown, specifically, the electrostatic spraying device includes a housing 7 and a cavity 13 which is arranged on the outer wall of the housing 7 and has openings at both ends. The housing 7 and the cavity 13 are all insulated. In this embodiment , the housing 7 and the cavity 13 are made of plastic.

[0027] In the inside of the housing 7, a high-voltage static electricity generating module 8 and a battery 4 that is connected to the high-voltage static electricity generating module 8 and used to supply power to the high-voltage static electricity generating module 8 are provided, and a precision potentiometer 9 is arranged on the high-voltage static electricity generator module 8 , the precision potentiometer 9 can be used to adjust the output voltage of the high-voltage electrostatic generator module 8 (DC2kV~DC30kV, the general v...

no. 2 approach

[0031] The second embodiment of the present invention relates to an operation method and a spraying process of electrostatic spraying or electrostatic spinning using the electrostatic spraying device of the first embodiment.

[0032] Draw an appropriate amount of spray solution into the syringe 11, turn the needle upside down, push it up, squeeze out the internal air bubbles, clean the needle 16 and insert it into the cavity 13 from top to bottom; turn on the push switch 1, the battery 4 starts to supply power, and high-voltage static electricity occurs The generator module 8 starts to work, and the negative high-voltage output line 10 transmits the high-voltage static electricity from the high-voltage electrostatic generator module 8 to the metal piece 15. Since the metal piece 15 is in contact with the needle 16 of the syringe 11, the needle 16 will be charged with a large amount of charge.

[0033] The operator holds the above-mentioned spraying device and touches the metal ...

no. 3 approach

[0038] The electrostatic spraying device according to the third embodiment of the present invention has the structure as attached Figure 5 As shown, specifically, on the basis of the first embodiment, the electrostatic spraying device of this embodiment adds a transparent observation area on the side wall of the cavity 13. In this embodiment, the transparent observation area can be A suitable transparent viewing panel 12 .

[0039] Add a transparent observation plate 12 on the side wall of the cavity 13, then the usage amount and remaining amount of the solution in the syringe 11 can be monitored in real time through the transparent observation plate 12, so that the electrostatic spraying process can be grasped at any time, and the spraying solution can be added in time Or replace the syringe.

Abstract

The invention relates to the technical field of electrostatic application, and discloses a device for solution electrostatic spraying. The device comprises a shell and a cavity arranged on the outer wall of the shell, wherein both the shell and the cavity are insulated; a high-voltage electrostatic generating module and a battery are arranged in the shell; the high-voltage electrostatic generating module is connected with a metal elastic piece arranged on the inner wall of the shell through a zero-potential line; a dismountable metal battery cover is arranged on the shell and is in elastic contact with the metal elastic piece after being mounted on the shell; openings are formed in the two ends of the cavity and are used for an injector with a syringe needle to insert; a metal piece with an opening is arranged at the bottom of the cavity; the syringe needle of the injector penetrates through the openings and contacts with the metal piece; in addition, a negative high-voltage input line is arranged between the high-voltage electrostatic generating module and the metal piece. The electrostatic spraying device integrates two functions of electrostatic spraying and electrostatic spinning, greatly reduces the size and weight, and can be held by hands of one person to be independently operated.

Description

technical field [0001] The invention relates to the technical field of static electricity utilization, in particular to a device for electrostatic spraying of solutions. Background technique [0002] Electrostatic spraying of solutions is divided into two forms: electrostatic atomization and electrospinning. Electrostatic atomization uses a high-voltage electrostatic field to atomize and split negatively charged liquids into tiny droplets, and the droplets follow the direction opposite to the direction of the electric field. Oriented movement, the final droplet particles are adsorbed and deposited on the surface of the object, which has been widely used in industrial fields such as painting, coating, and nano-powder manufacturing; electrospinning is a special form of electrostatic atomization of polymer fluids. At this time, atomization The split material is not a tiny droplet, but a tiny polymer jet. The jet is split, stretched, and thinned in the air to form micro-nano fib...
