Background

The mask is made of cotton cloth or melt-blown cloth material with a filtering function, and simultaneously covers the mouth and the nose and part of the face, so that the mask is used for isolating own breathing and spray from the outside, but people neglect an important factor, namely, the breathing is just by the nose, the mouth belongs to the digestive system category, the mouth and the nose do not exert the same function, the traditional mask shares a filtering system with the mouth and the nose, the mouth spray and the waste gas of the people are easily sucked into the mask from the nasal cavity, and discomfort and secondary infection are easily caused to the people.

Masks have become an indispensable device in daily life. However, when people need to eat and drink water outdoors or perform other related communication activities, the user cannot take off or wear the mask conveniently. In daily activities, the mask is inconvenient to store after being removed, and is in the way of being held in the hands and is not sanitary when being placed in other places. In the prior art, the mouth and nose of the mask are tightly wrapped, and the user can feel inconvenient to drink water and speak. If a movable mouth is opened at the mouth, the mouth can be conveniently used for feeding or speaking and the like, and the trouble of wearing the mask is solved.

The simple activities of speaking, drinking water, taking medicine, whistle and the like of people can be met without taking off the mask, the trouble of taking off the mask is solved, and the decorative patch can bring wonderful experience to users. However, the mask with the structure has poor aesthetic property, and the magic tape arranged around the opening part has an influence on respiratory effect due to air impermeability, and particularly after the cover body is uncovered, a user is not different from the mask to take off, so that the mask is not beneficial to use in an environment easy to be infected.

The disclosed Chinese patent of invention (CN 106798985A) is similar to the prior art that the mask is split into a nose mask and a mask through a zipper, a magic tape, a buckle and other devices, so that the discomfort caused by the fact that waste gas droplets in the oral cavity and the nasal cavity are alternately inhaled into the body is eliminated, and the problem that the prior mask is inconvenient for people to communicate with the mouth or eat is solved through the splitting device. The same problems with the disadvantages are: when the mask is removed, the mouth of the user is completely exposed to the external environment, and there are problems of both the phenomenon of outgoing spray and the problem of spraying spray in the air sucked through the mouth.

In summary, it is necessary to design a device that can filter and protect the nasal cavity breathing air in real time for a long time during use, and at the same time, the mouth of the mask can be conveniently opened, especially after the mouth is opened, the device can effectively prevent the droplet from being discharged out, and can prevent the droplet scattered in the external air from being sucked into the oral cavity.
