Description
Technical Field
The utility model belongs to the technical field of daily care products, and particularly relates to a mask capable of preventing glasses from fogging.
Background
The mask is a sanitary protective article, is worn at the position of the mouth and the nose and is used for filtering air entering a nasal cavity so as to achieve the purpose of preventing harmful substances in the air from entering the lung of a human body through breathing, for example, when the mask is worn, substances such as dust, pollen, haze and the like can be prevented from entering the lung of the human body, particularly, the mask is important for preventing germs and viruses and has a very good protective effect when the mask is worn when respiratory infectious diseases are prevalent or work is carried out in an environment polluted by dust and the like. The medical mask has high requirements on the barrier effect of air sucked into the lung, and the mask needs to be tightly protected against the mouth and the nose so that germs and viruses cannot invade a human body through the nasal cavity.
Medical surgery gauze mask quantity is huge, and not only medical personnel will change a large amount of gauze masks every day, and the people all wear during epidemic prevention, contains a large amount of ordinary people who takes glasses wherein, especially in winter and spring season, and a large amount of water smoke can be gathered on the glasses piece to the gas of exhalation, has brought the potential safety hazard for the people's trip. At present, aiming at prevention, control and treatment with high infectivity and high pathogenicity, particularly, medical workers need to wear a mask and wear goggles simultaneously in the treatment process, the existing disposable surgical mask is only provided with a soft metal strip on the upper edge of the mask, so that the mask is attached to the face as much as possible, but airflow thrust generated by breathing is limited due to the limited attaching force of the metal strip, the mask cannot block moisture from being sprayed out from the upper edge of the mask, and due to the fact that the upper part of the mask is not tight in sealing, the exhaled hot air can form water mist on the goggles or glasses, the observation sight is influenced, and obstacles are brought to daily travel or prevention, control and treatment.
The utility model patent of application number CN202020156068.X discloses a prevent gauze mask that glasses hazed, through set up one in the gauze mask inboard and hinder the gas area to set up and hinder gas area one end and be the wave limit, it is pressed down the back and is reverse to paste clothes in bridge of the nose and both sides face, and ascending expiration arrives at and hinders the gas area, and the air current oppresses and hinders the gas area and tightly laminates on people's face and bridge of the nose, thereby prevents to exhale and to wash the lens upwards and form the water smoke. However, because the contour of the face at the nose is complicated and the contour of the face of different people is different, the air barrier belt is difficult to fit the contour of the face seamlessly, and moisture entering the gap can still contact the lens to generate fog.
SUMMERY OF THE UTILITY MODEL
