Description

Self-attaching high-air-tightness mask simulating gecko skin

Technical Field

The utility model belongs to the technical field of protection, and relates to a self-attaching high-air-tightness mask simulating gecko skin.

Background

The mask is an indispensable protective article for dust prevention, wind prevention, haze prevention, virus prevention and the like in life, and can effectively filter tiny particles such as pollen, dust, spray, acid mist and the like or particles containing harmful microorganisms such as viruses and the like in air. The mask is generally classified into a general mask, a general medical mask, a medical surgical mask, a medical protective mask, and the like. The common mask is made of gauze, cotton cloth and the like; the medical surgical mask is generally divided into three layers, namely a waterproof layer, a filter layer and a comfortable layer from outside to inside, wherein the waterproof layer can prevent blood and saliva from permeating into the mask; the medical protective mask is also divided into three layers, wherein the inner layer is gauze or non-woven fabric, the middle layer is a single-layer or multi-layer superfine polypropylene fiber melt-blown material layer, and the outer layer is a non-woven fabric or ultrathin polypropylene melt-blown material layer. The protective effect of the mask is closely related to the air tightness and the filtering performance of the mask. However, the existing common masks mostly adopt two ear straps to be worn on ears, and the mask body is attached to the face skin only through the bending of the nose bridge strip, so that the tightness between the mask and the face skin is poor, and when breathing, air enters and exits from the upper edge or two sides of the mask, micro-particles or viruses in the air cannot be well filtered, and diseases cannot be effectively prevented. Meanwhile, the mask is manufactured in a standardized mode, the mask body and the nose bridge strip are difficult to fit with people with different face shapes, and the applicability of the mask is poor. In addition, in chilly season, because the seal of gauze mask is poor, the last edge entering air of gauze mask and face laminating department will be followed to the steam of exhalation, when steam met low temperature glasses lens, steam just can condense in the lens formation water smoke, hinders the sight, is difficult to the clear surrounding environment of observing, especially to the myopia personnel of riding, because the lens can not be cleaned always to the process of riding, but water smoke can continuously condense, and current gauze mask has brought a great deal of inconvenience and potential safety hazard for riding.

The gecko can help the gecko to walk around the wall due to the uneven fold structure of the sole, and the structure is composed of tens of thousands of small setae with the diameter of several micrometers and the length of 30-130 micrometers. The Gecko paw has an adhesion force of up to 1000N as reported by the Proc.Kellar Autum of Louis Clark school and coworkers in Nature (Nature 2000, 405: 681-685). The bionic gecko skin material researched and developed by imitating the morphological structure of the gecko toes is applied to the fields of buckles, stickers and the like, the bionic gecko skin material can be adsorbed on the surfaces of objects such as glass, desktops, walls and the like by Van der Waals force, and the bionic gecko skin material can be repeatedly used and does not leave residues due to the weak electromagnetic attraction of the Van der Waals force.
