Description

Anti-fogging mask

Technical Field

The utility model relates to the technical field of masks, in particular to an anti-fogging mask.

Background

The mask is an important defense line for preventing respiratory infectious diseases, and can prevent the spray of droplets from a patient, reduce the amount of droplets and the spray speed, block the droplets containing viruses and prevent the inhalation of a wearer. At present, the mask becomes a daily necessity for people.

For the person who wears glasses, when wearing the gauze mask, the gas of exhalation rises to glasses along bridge of the nose both sides, and especially when weather is colder, the hot gas of exhalation condenses to the lens that the temperature is low and leads to glasses to haze influence the sight, gives people and causes the inconvenience. The industry has focused on this problem and has made some improvements to the mouth mask to address the problem of fogging of the glasses, such as:

1. through setting up the venthole above the bridge of the nose presss from both sides, make gaseous follow the ascending direction along the bridge of the nose from the venthole discharge, avoid gaseous along the oblique lens that rises in bridge of the nose both sides, prevent glasses fogging, this kind of structure is equivalent to the bridge of the nose of normal gauze mask presss from both sides the top and sets up the venthole, still need set up the second grade bridge of the nose in the venthole top and press from both sides, the upper and lower direction width size that leads to the gauze mask is great, can extend to very close to eyes below region when wearing the use, easy eye discomfort, moreover, because the existence of venthole, also influence the leakproofness of gauze mask, gauze mask protective effect receives the limitation.

2. The drying agent is filled in the middle layer of the mask, and the condensing part for condensing hot gas is arranged on the inner side of the breathable fabric of the mask, so that exhaled gas is adsorbed by the drying agent and condensed by the condensing part, the middle layer and the outer layer can be detached in non-low-temperature seasons to be used as a common mask, and the middle layer or the outer layer can be assembled to prevent glasses from being fogged according to conditions in low-temperature seasons; the structure is complex, high in cost, complex in production process, troublesome in use and operation, not suitable for disposable masks and not beneficial to large-scale popularization.

3. Through set up the condensation on the gauze mask and absorb water the strip, the condensation is absorbed water the strip and is included multilayer condensation metal mesh, the layer that absorbs water, and multilayer condensation metal mesh embedding is in the layer that absorbs water, and when the vapor of people's exhalation got into the condensation and absorbs water the strip, was earlier condensed into water by the condensation metal mesh, and then the water of condensation is absorbed the water layer and is inhaled futilely, and the layer 62 material that absorbs water is similar urine non-wet's material or other materials that absorb water on the market. Similarly, this kind of structure, it is comparatively complicated, with higher costs, the production process is loaded down with trivial details, uses the troublesome poeration, especially is not suitable for disposable gauze mask, is unfavorable for extensive popularization.

Therefore, the applicant researches a new technical scheme elaborately, and the mask is simple in structure, easy to produce and manufacture, applicable to disposable masks and beneficial to large-scale popularization.
