After installation, the filter assembly 1 is divided into two parts from a horizontal center line by the isolation assembly to form an upper nasal external upper cavity and a lower oral cavity which are relatively isolated from each other, and when the pressure of the upper nasal external upper cavity is greater than that of the lower oral cavity, the directional valve 5 is opened; when the pressure in the extraoral lower chamber is equal to or greater than the pressure in the extranasal upper chamber, the directional valve 5 closes.

The mouth-nose directional separation mask adopts a directional isolation technology to form an external nasal upper cavity and an external oral lower cavity inside the mask. Compared with the existing common mask, the exhaust gas is completely discharged in the mask during expiration, and more exhaust gas is inhaled during inspiration again. When the mask provided by the invention is used for breathing by a nose, half of exhaust gas exhaled during exhalation enters the external lower cavity, and only half of exhaust gas is remained in the external upper cavity, so that the exhaust gas inhaled during rebreathing is less than that of the common mask. If the nose is used for inhaling and exhaling through the mouth, the exhausted gas is in the lower oral cavity during exhalation, and the upper nasal cavity is almost free of the exhausted gas during inhalation. The mask of the invention can greatly reduce the exhaust gas inhalation compared with the common mask. In addition, the inhalation of harmful substances such as saliva spray and the like can be avoided.

Compared with the existing mask with the completely separated mouth and nose, the existing mask with the completely separated mouth and nose has large exhaust resistance because the surface area of the cavity is small when the mask breathes by the nose. According to the mouth-nose directional separation mask, when the nose exhales, the pressure of the upper nasal cavity is higher than that of the lower oral cavity, the directional valve 5 is opened, and exhaust can enter the lower oral cavity, so that exhaust resistance is low, and breathing is smooth. In the existing mask with the completely separated mouth and nose, waste gas is completely discharged outwards through the cavity of the mask when the nose exhales, and the waste gas is sucked more due to the small surface area and the slow discharge speed. According to the mouth-nose directional separation mask, when a nose is used for exhaling, half of exhausted gas exhaled during exhalation enters the external lower cavity, only half of the exhausted gas is left in the external upper cavity of the nose, the surface area of the whole mask can be used for outwards discharging the exhausted gas, and the discharging speed is high. In addition, when a user has to inhale air by mouth due to nasal obstruction and the like, the existing mask with the mouth and the nose completely separated can only intake air through the cavity surface of the mask outside the mouth during air inhalation, and the air intake resistance is large due to small surface area. When the mouth and nose directional separation mask is used for inhaling air, when the pressure of the lower oral cavity is lower than that of the upper nasal cavity, the directional valve 5 is opened, so that air can be inhaled through the surface area of the whole mask, the air inhalation resistance is small, and the breathing is smooth.

The mouth and nose directional separation mask can be in an ear-hanging type or a head-wearing type. When mouth and nose directional separation gauze mask is the ear-hanging type, fastening components include about two cover areas, and left cover area both ends are connected respectively detain the upper portion and the lower part of pressing the card strip left end fastening rope, right cover area both ends are connected respectively detain the upper portion and the lower part of pressing the card strip right-hand member fastening rope.

When the mouth and nose directional separation mask is a head-wearing type mask, preferably, the fastening assembly comprises an upper mask belt and a lower mask belt, two ends of the upper mask belt are respectively connected with the upper parts of the two fastening ropes, and two ends of the lower mask belt are respectively connected with the lower parts of the two fastening ropes.

According to the mask, the filter assembly 1 is detachable and replaceable, and the isolation assembly and the fastening assembly can be reused. The isolation assembly and the fastening assembly may be sterilized for repeated use.
