Description

Mask capable of preventing glasses from falling

Technical Field

The utility model relates to a respiratory protection technical field specifically is a gauze mask that prevents glasses and drop.

Background

The haze weather in many areas is very serious, the breathing health of residents is directly influenced, serious people can cause various respiratory diseases, along with the improvement of living standard, people pay more and more attention to the health of the bodies, the mask is used as an optimal breathing protection article, a certain filtering effect is realized on air entering the lung, harmful gas, smell, spray and the like can be effectively blocked to enter and exit from the mouth and the nose of a wearer, and therefore the mask is widely applied to daily life of people, hospitals of various sizes and other special work posts. Based on the condition of using the gauze mask of the wearer, reform transform the gauze mask step by step, solved a lot of shortcomings including deodorant, prevent that glasses from hazing etc. until developing today, the gauze mask type that is applicable to different wearers and different wearing environment has appeared.

However, when the existing mask becomes an essential article for people to go out and needs to be worn for a long time, some defects of the mask are gradually revealed, such as: 1. the existing mask is generally worn by ears, if ear ropes are too loose, the respiratory protection quality cannot be guaranteed, if the ear ropes are too tight, the ear burden can be increased, and the ear pain can be caused after the mask is worn for a long time; 2. the mask worn by a person wearing glasses has many troubles, such as glasses fogging, glasses falling easily and the like, the existing mask structure has a plurality of methods for solving the glasses fogging, but a good solution is not provided for the problem that the glasses fall easily. The glasses legs of the glasses and the ear ropes (head ropes) of the mask share one ear, and interference exists between the glasses and the mask, so that the glasses are further dropped. Therefore, the utility model provides a gauze mask suitable for the people who wears glasses wears.

Disclosure of Invention

The utility model aims to solve the defects of the prior art, and provides a mask which is convenient to wear, reduces ear burdens and can effectively prevent glasses from dropping based on mutual interference between the glasses legs of the glasses and the ear ropes (head ropes) of the mask.

The purpose of the utility model is realized through the following scheme:

a mask for preventing glasses from falling comprises a mask body, a glasses leg fixing device, a head rope and a head rope connecting piece; the head ropes comprise a left head rope and a right head rope, wherein the left head rope and the right head rope are defined according to the left and the right of a wearer; the glasses leg fixing devices are provided with head rope through holes and glasses leg through holes, the size of the head rope through holes needs to meet the requirement that the friction force range between the glasses leg fixing devices and a head rope accords with the actually required friction force range, the preferable glasses leg through holes can be through holes with rectangular radial sections, so that glasses legs with different thicknesses can be adapted, the two glasses leg fixing devices are respectively arranged on the left head rope and the right head rope, the head ropes penetrate through the head rope through holes and are movably connected with the glasses leg fixing devices, and the glasses leg fixing devices can move back and forth along the head ropes under the action of external force with certain size; the head rope connecting piece is provided with a connecting perforation, one end of a left head rope is arranged on the mask body, and the other end of the left head rope penetrates in from the left end and the right end of the connecting perforation and is movably connected with the head rope connecting piece; the one end of right side first rope sets up on the gauze mask body, and the other end of right side first rope penetrates, the left end is worn out from connecting fenestrate right-hand member, with first rope connecting piece swing joint, connects fenestrate left and right-hand member and corresponds the left and right side of wearing person respectively.

Different people wear different glasses or different people wear the same glasses due to different facial structures of different people, the angle positions of the glasses legs on the two sides of the head bag have certain difference, the habits of different people on wearing the glasses are slightly different, some people like wearing the glasses higher, and some people like wearing the glasses lower, so the glasses leg fixing device comprises an upper base layer and a lower base layer which are connected in a rotating manner; the head rope is perforated and arranged on the lower base layer, and the glasses legs are perforated and arranged on the upper base layer.
