Abstract

The invention discloses a cavity-separated type breathing mask, belonging to the technical field of masks. The cavity-separated type breathing mask comprises a mask body, wherein ear bands are arranged at the two ends of the mask body; the two sides, corresponding to nostrils of a human body, of the mask body are each provided with a nasal ventilation cavity; the outer layer of each nasal ventilation cavity is covered with a nasal filter screen which is detachably installed; the inner layer of each nasal ventilation cavity is covered with a cover plate; each nasal ventilation cavity is connected with a nostril plug; and a mouth filter is arranged at the position, corresponding to the mouth of the human body, of the mask body. The cavity-separated type breathing mask adopts the mouth and nose separated cavity type breathing, mouth breathing and nose breathing are separated, better air permeability is achieved, and oxygen deficit caused by the fact that carbon dioxide exhaled by the human body is inhaled by the human body without being exhausted in time in the mask is avoided. The cavity-separated type breathing mask has better edge sealing performance and good ventilation effect inthe mask, and therefore has better filtering and protecting performance. Meanwhile, the cavity-separated type breathing mask reduces the raw materials and decreases the use cost.

Description

Technical field [0001] The present invention relates to the technical field of masks, in particular to a split-cavity breathing mask. Background technique [0002] Masks are generally worn on the mouth and nose of a person to filter the air in and out of the nose to block harmful gases, odors, and droplets. Common masks are divided into three layers: inner, middle, and outer. The inner layer is Ordinary sanitary gauze or non-woven fabric, the middle layer is made of ultrafine polypropylene fiber meltblown material layer. In some harsh environments, such as infectious disease areas, virus laboratories, and toxic chemical tests, the requirements for masks are even higher. [0003] At present, the existing mask design has two defects. On the one hand, the existing masks are thick and tightly attached to the face, and have poor air permeability. The mask will be recessed when you breathe in, and the mask will be raised when you breathe out, resulting in poor protection of the mask, e...
