Title: dewetting askin mask
Inventor: NAM SE JIN
IPC: A62B18/08
Filed: 2021-06-22
Abstract: In a prior art, most masks for blocking fine dust have a structure of adhering to the nose by using wires, so lifting occurs inevitably and fogging occurs due to air discharge during exhalation, in particular, moisture in the winter. In addition, due to the use of a thick KF mask, it is difficult to ventilate the inside of the mask and more difficult to discharge moisture. Reuse becomes more difficult due to the unpleasantness of moisture inside the mask. As a way to solve the problem, the purpose of the present invention is to add a silicone nose harmless to a human body instead of wires. An MB electrostatic filter is inserted inside the mask in order to block fine dust and external particles. The filter is made by coupling fine fibers to each other to make it difficult for foreign substances to pass therethrough. In order to overcome the disadvantage of the MB filter in which the electrostatic effect is reduced when moisture is generated, an Askin material with a fast vaporization rate is used. The Askin material with excellent elasticity and breathability can be used multiple times and dissipate heat faster than other materials because of a large contact area with the skin. The Askin material, as a cooling fabric, has a fast moisture absorption rate and shows excellent performance by having an ultraviolet-blocking function.
