Description

Mask with inspiration and expiration separation structure

Technical Field

The utility model relates to a gauze mask specifically is a gauze mask with breathe in expiration isolating construction, belongs to personal protection articles for use technical field.

Background

At present, based on the requirement of epidemic prevention of new coronary pneumonia, people need to wear a mask for a long time to carry out personal protection in many public places, but the traditional mask worn by people is not separated in inspiration and expiration, so that a large amount of foul smell exhaled by a human body is blocked by the mask and is stored in the mask, most of the inhaled foul smell is previously exhaled foul smell during inspiration, and the inhaled gas is neither fresh nor sanitary, so that neither inspiration nor expiration can be smooth. In addition, the foul smell exhaled by the human body is close to the body temperature of the human body, and a large amount of water vapor is retained in the mask, so that a wearer can feel stuffy and uncomfortable on the face, and particularly when the weather is hot in summer, the wearing comfort of the traditional mask is poor.

Therefore, the invention designs the mask with the inspiration and expiration separation structure, the user can inhale fresh air completely by inhaling and exhaling each time, and exhaling each time can discharge exhaled foul air out of the mask completely, so that the user can breathe smoothly, the face in the mask is kept cool, and the wearing comfort of the mask is improved.
