Description

Wind wall type reusable mask

Technical Field

The utility model relates to a sanitary installation field, concretely relates to wind wall formula repeatedly usable's gauze mask.

Background

The mask is a sanitary article, generally refers to a device which is worn at the mouth and nose part and used for filtering air entering the mouth and nose so as to prevent harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer, and is made of gauze or paper and the like. The mask has a certain filtering function on air entering the lung, and has a very good effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like.

The existing masks on the market are divided into two types, one type is an air filtering type mask, the other type is an air supply type mask, although the principles of the two types are different, the effect can be achieved only by mechanically sealing the mouth and the nose, once the sealing is in a problem, the isolation effect is obviously reduced, and the isolation performance is not lost in a mechanical mode, the mechanical closed type mask has a problem that a sealing adhesive tape is attached to the face too tightly, the isolation performance can be improved, but the sealing adhesive tape of the mask can generate larger pressure on the face, the wearing time is longer, the face strange marks are serious, summer is stuffy and hot, suffocating and the like, and is very uncomfortable, but still can not ensure the loss in a thousand, the sealing specifications of the masks are consistent due to different face types of everyone, so that different people wear the masks, local sealing instability always occurs, and the current medical care personnel can ensure the loss in a thousand, only multiple layers of protection can be arranged, such as a mask (a plurality of masks), a protective hat, a protective garment and the like, although each layer is different from the main body of the protection, the mask and the protective hat protect the mouth and the nose at the same time, so that the reason is mainly that the existing mask has poor isolation capability and poor virus filtering performance; secondly, if the closure strip is generally or loosely attached to the face, the comfort of the face can be replaced, but the risk of infection is greatly increased, which is not generally adopted.

Secondly, the existing mask adopts mechanical isolation, such as a disposable mask, an N95 mask and the like, to achieve the protection purpose by adopting the isolation mode, but the isolated substances have requirements on the diameter (for example, the filtering efficiency of the N95 type mask on particles with the aerodynamic diameter of 0.075 mu m +/-0.02 mu m reaches more than 95%), the too small substances cannot be isolated due to material defects, such as the isolation of viruses, the isolation purpose can be achieved only by isolating virus attachments, such as the isolation of substances like spray and dust, once the single virus exists, the diameter of the single virus is very small, the isolation effect cannot be achieved theoretically, and the mask is put to practical use; it is used.

The mask aims to help people to breathe clean, pure and nontoxic air, and various modes of breathing the clean air are available, one mode is filtration, namely the traditional conventional mask, the mode does not need to bear an air tank, but the effect is poor, and when a large amount of health-care gas or virus exists in the air, the mask cannot be used generally; the other is to breathe by carrying a clean air source, such as a piggyback air tank, which ensures the cleanness of the breathable gas, but the piggyback air tank is long in use time, is fatal in case of overtime, and is very inconvenient, so that if a device combining the advantages of the two masks can be developed, the device is of great significance to the current technical improvement.

Disclosure of Invention
