Description

Mouth fog prevention mask

Technical Field

The invention relates to the technical field of masks, in particular to an oral cavity fog prevention mask.

Background

The mask is a sanitary article, is generally worn on the mouth and nose for filtering air entering the mouth and nose so as to achieve the effect of blocking harmful gas, smell, droplets, viruses and other substances, and is made of gauze, paper and the like. The mask has a certain filtering function on air entering the lung, and has a very good effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like.

The filtering material of a good protective mask has the following three conditions that the filtering efficiency is high under the condition that the mask is well closed with the face of a user, the breathing resistance is small, and the user feels comfortable. The material of the filter material for the dustproof mask is various, and comprises common fabrics, animal hair, non-woven fabrics and the like. The mask is made of an activated carbon felt material which is very popular in the national standard, and the mask needs to be suitable in size and correct in wearing mode to be effective. Commercially available masks generally fall into two categories, rectangular and cup-shaped. The rectangular mask has a protective function only by adopting a structure with at least three layers of paper. The iron wire on the gauze mask is pressed on the bridge of the nose to the user, and then the whole gauze mask is spread along the bridge of the nose, so that the efficiency can be exerted, dirt such as dust, bacteria and the like in a lot of outside air is often accumulated on the outer layer of the gauze mask, exhaled bacteria and saliva are blocked on the inner layer, therefore, two surfaces can not be used alternately, otherwise, the dirt stained on the outer layer is directly attached to the face to be inhaled into the human body, and the respirator becomes an infection source. When the mask is not worn, the mask is folded and put into a clean envelope, and one surface of the mask close to the mouth and the nose is folded inwards, so that the mask is prevented from being conveniently plugged into a pocket or hung on the neck;

the visual eye is one of the ametropia, and the eye forms a focus in front of a retina after parallel rays enter the eye, so that an external object cannot form a clear image on the retina, and a patient feels that a distant object is not clear, but has better adaptability to a near target. The near point of myopia and, with the near point of emmetropia the same or slightly near, because the myopia can only see closely, the distance point is limited, consequently call as myopia, and nowadays, most people all suffer from myopia, when myopia person must take the gauze mask, because gauze mask and the contact department of user's bridge of the nose have the space, breathe the fog that produces and can pass through the space upwards, attach to glasses lens surface, can influence the definition that myopia person looked the thing when wearing the gauze mask. Therefore, an oral fog prevention mask is provided.
