Description

External ear hanging mask

Technical Field

The utility model belongs to the technical field of medical equipment's technique and specifically relates to a take gauze mask is hung to external ear.

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 gases, air temperature, spray, viruses and other substances, and is made of gauze, non-woven fabrics or 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.

For example, chinese patent No. CN210143886U discloses an easily-fixed mask, which comprises: the mask body, hang rope, nose bridge bracket. The mask body is made of flexible material and is contacted with the nose, mouth and other parts of people. The hanging rope has two, and it connects respectively in the both sides of the cover body, and the nose bridge bracket is flexible silica gel material, sets up on the medial surface of the cover body, and the shape of nose bridge bracket is similar with people's nose.

The hanging rope is usually made of elastic rubber rope, when the mask is worn, a wearer hangs the hanging rope at two sides of the mask body behind two ears, and thus the mask body is worn on the face. However, the difference of the sizes of the faces of the wearers also causes slight difference of the sling in the preparation process, so that the slight difference of the sling is caused. The hanging rope is fixedly connected with the cover body, and can only generate limited elastic deformation relative to the cover body. When meeting the great wearer of face, the string of rope is hung and need produce very big deformation when the cover at ear rear portion to lead to the string of rope also can increase to the effort of ear, this just leads to the string of rope because the reaction force of self is tightened up the mark to wearer's ear, causes wearer's discomfort. Meanwhile, when the wearer is a child, the face is small, so that the mask body and the face are loose, and the mask protection effect cannot be achieved. Therefore, it is desirable to provide a mask with an adjustable length of the hanging string.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an external ear sling gauze mask can adjust the distance between the tie point of hangers rope both ends and the cover body to can avoid the hangers rope to reining in the trace of ear, can also make the laminating that the cover body can be inseparable simultaneously facial, finally can make the cover body play effectual guard action.
