On the one hand, current gauze mask is thick and the wainscot portion is more tight, and the gas permeability is poor, and the main gauze mask of breathing in can recess, and the main gauze mask of breathing in can be protruding, causes the gauze mask protective capacities variation, especially wears the medical staff of gauze mask because of the operation for a long time, wears the gauze mask that the gas permeability is poor for a long time, and medical staff can be faint on the post because of the oxygen deficiency. On the other hand, the existing mask covers the nose and the oral cavity integrally to cause the internal circulation type absorption of carbon dioxide exhaled by a human body, about 60% of the carbon dioxide is absorbed by the mask during each air exhaling and air exchanging process, the continuous internal circulation type absorption of the carbon dioxide causes vicious circulation, the exhaled carbon dioxide concentration is gradually increased, the mask is seriously lack of oxygen and the blood sugar is increased due to the overlong wearing time, and various concurrent symptoms such as dizziness, brain distension, chest distress, vomiting, syncope and the like of the human body are presented.
Disclosure of Invention
The invention aims to solve the problems, and provides a chambered breathing mask to solve the problems that a common mask in the prior art is poor in air permeability and forms carbon dioxide internal circulation absorption after being worn for a long time, so that a person wearing the mask is difficult to breathe, and the mask is married, swollen, vomited, faint and the like. The invention adopts the design layout of the cavity-divided mask, achieves the breathing of the mouth and the nasal cavity, and avoids the phenomena of dizziness, brain distension, chest distress, vomiting, syncope and the like caused by long-time wearing of the mask and poor air permeability of the mask.
In order to achieve the purpose, the invention provides the following technical scheme:
the invention provides a chambered breathing mask, which comprises a mask body, wherein ear belts are arranged at two ends of the mask body, two sides of the mask body, which correspond to nostrils of a human body, are respectively provided with a nasal ventilation cavity, the outer layer of each nasal ventilation cavity is covered by a detachably mounted nasal filter screen, the inner layer of each nasal ventilation cavity is covered by a cover plate, each nasal ventilation cavity is connected with a nostril plug, and a mouth filter is arranged on the mask body, which corresponds to the mouth of the human body.
Furthermore, the mask body adopts a four-layer structure, and is respectively provided with a surface cloth layer, a heat-preservation fiber layer, a filtering layer and an inner cloth layer from outside to inside.
Furthermore, the nose filter screen is of a four-layer structure and is respectively provided with a surface cloth layer, a heat-preservation fiber layer, an activated carbon filter cotton layer and an inner cloth layer from outside to inside.
Furthermore, one nostril is inserted and is passed through the hose and be communicated with one the nose ventilation chamber, the nostril is inserted for screw thread formula silica gel concentric reducer nostril.
Further, the inner layer of the mask body is provided with a sealing piece.
