Description

Low-carbon refreshing mask

Technical Field

The disclosure relates to the technical field of masks, in particular to a low-carbon refreshing mask.

Background

The mask is a daily product in our life and has the following main effects. 1) And (3) isolating germs: in seasons suffering from virus abuse or occasions with high virus concentration, a reliable, sanitary and safe mask can isolate virus and reduce the infection probability; 2) protecting others: the mask is also used for protecting people around when people suffer from infectious diseases such as cold; 3) anti-haze or other pollutant inhalation: some masks can purify air to a certain extent, so that a wearer can inhale haze or other pollutants as little as possible; 4) keeping warm: in cold winter, the mask can be worn to keep warm, so that cold air allergy is prevented.

Traditional masks are divided into two major categories, the first category being medical masks (generally without a breather valve) and the second category being masks with a breather valve. Generally, the medical mask comprises a mask body and a tightening belt, wherein the mask body is divided into an inner layer, a middle layer and an outer layer, the inner layer is made of a skin-friendly material (common sanitary gauze or non-woven fabric), the middle layer is an isolation filter layer (superfine polypropylene fiber melt-blown material layer), and the outer layer is a special material antibacterial layer (non-woven fabric or ultrathin polypropylene melt-blown material layer). The mask with the breather valve is generally formed by combining a breather valve shell, a valve and a mask cup body, and the breather valve formed by the breather valve shell and the valve is fixed on the mask cup body. The user wears in face, and the filter layer that inspired air passes through in the gauze mask cup gets into user respiratory, and the exhale gas exhales smoothly through unidirectional valve, accomplishes a respiratory process. However, if the user is the source of a disease, the breathing valve mask cannot filter the exhaled air, and cannot effectively protect people around the breathing valve mask.

In addition to the inherent functions of conventional masks, whether medical masks or masks with breathing valves, the ability to protect the wearer during major public health events is still desired to be improved.

The overall shape of the carbon dioxide absorber may be spherical, cylindrical, prismatic, or the like. The overall shape of the closed vessel 31 may be spherical, cylindrical, prismatic, or rectangular.

In the above preferred embodiment, a removable cover film may be further provided to cover the surface of the closed container where the through hole is provided; when the mask is not needed, the covering film covers the surface of the closed container with the through hole, so that the sealed preservation of the carbon dioxide absorbent is realized; when the mask is needed to be used, the covering film can be torn off, the through hole of the closed container is exposed, and carbon dioxide exhaled by a user can pass through the through hole and then pass through the bag to be absorbed by the carbon dioxide absorbent in the bag.

In the above preferred embodiment, the air-permeable and dust-proof material may be a nonwoven fabric such as a meltblown nonwoven fabric, a spunbonded nonwoven fabric.

In the above preferred embodiment, the material of the closed vessel may be plastic, rubber, or the like.

In the above preferred embodiment, the carbon dioxide absorbing device 3 may be embedded in the mask body, and at least the side facing the outside (the side opposite to the side facing the human body) is made of transparent material, so as to be convenient for determining whether the carbon dioxide absorbent has failed; for example, in the case of soda lime in the form of pink cylindrical particles, the absorption of carbon dioxide changes from pink to light yellow or off-white, and although the carbon dioxide still changes to pink after being used and standing for a long time, the absorption amount is reduced and the carbon dioxide cannot be used any more.
