Multifunctional mask

Abstract

The invention relates to a multifunctional mask, which comprises a mask body and an elastic band, the mask body is made of plastic, and an air inlet channel is formed in the mask body; the front faceof the mask body is covered with detachable filter cloth, a plurality of array protrusions used for supporting the filter cloth are arranged on the front face of the mask body, and array area flow channels communicated with the air inlet channel are formed between the array protrusions, a breathing component is arranged on the back surface of the mask body, is made of a soft rubber material and isprovided with a breathing cavity matched with the nose and the mouth; an air inlet and an air outlet are formed in the front cavity wall of the breathing cavity, an air inlet one-way valve is arranged on the air inlet, and an air outlet one-way valve is arranged on the air outlet. By the adoption of the mask, the area, tightly attached to the face, of the mask is small, the mask can be completelyattached to the nasal cavity and the oral cavity breathing area, the sealing performance is good, meanwhile, air exhaled from the nasal cavity or the oral cavity cannot wet cloth, the cloth is largein effective breathable area and high in comfort degree, and the mask is long in service life, convenient to replace filter cloth and low in use cost.

Description

technical field [0001] The invention belongs to the field of protective equipment, and more specifically relates to a multifunctional mask. Background technique [0002] With the rapid development of the economy, people's health has received widespread attention from the society, and at the same time, it has driven continuous innovation and development in the field of protective equipment. At present, in certain workplaces or places with special living environments, such as hospitals, epidemic areas, areas with severe smog, dust workplaces, etc., there are relatively high concentrations of germs or dust in the air, which seriously endangers people's health. Masks have become the necessary protective equipment for people in the above-mentioned workplaces or living environments. [0003] At present, there are many kinds of masks available, which can be roughly divided into medical masks, dust masks and smog masks according to the occasions of use. The main structure of these...

AI Technical Summary

Problems solved by technology

[0004] (1) The facial curvature of the human body varies from individual to individual, and the existing mask structure cannot conform to the facial curvature characteristics of all individuals, resulting in poor sealing of the edge of the mask, and cannot effectively exert the dust-proof and anti-infection effect of the mask;

[0005] (2) The gas exhaled from the nasal cavity or oral cavity escapes from the alar position of the nose, causing water mist to form on the surface of the wearer's glasses, which affects work, especially for doctors, which seriously affects the operation or even makes it impossible to perform the operation;

[0006] (3) The contact area between the mask and the face is large, and the face is difficult to breathe; the mask fabric that fits the face is not breathable, and the effective ventilation area is small, which makes the wearer's breathing difficult, and the face is sweaty and hot;

[0007] (4) The air exhaled from the nasal cavity or oral cavity is easy to wet the cloth, resulting in a decrease in the air permeability of the cloth, carbon dioxide stays in the breathing cavity and causes breathing difficulties, which greatly affects the comfort of wearing a mask; and the cloth in a warm and humid environment is easy to Breeding bacteria, need to be replaced frequently, increasing the cost of use;

[0008] (5) Silicone masks on the market generally have poor sound transmission effects. Those with a large filter area block the line of sight, and those that do not block the line of sight have difficulty inhaling. The exhaust valve hole is exposed, and the direct discharge air is sprayed far away. Air and water pollution from outside
