Description

Multifunctional epidemic prevention device and method for preventing virus and dust

The technical field is as follows:

the invention relates to the technical field of epidemic prevention equipment, in particular to a multifunctional epidemic prevention device and an epidemic prevention method for preventing virus and dust.

Background art:

the field of epidemic prevention of infectious diseases transmitted through breathing air is lack of reliable and effective portable epidemic prevention equipment, but unknown infectious diseases still continue to appear and are also variable. The development of vaccines and drugs is not necessarily satisfactory in time. Although the mask has a certain prevention effect, the breathing area is too small, the breathing is difficult, the image and the communication identification are influenced, the mask is troublesome, people feel not respected, the mask is a prejudice, and the mask or a cap is forbidden to be used in some places for safety. Moreover, the mask must be worn tightly and kept at a distance to basically prevent infection, the mask is not protected tightly, and the risk of infection still exists. Although some epidemic prevention articles have been invented, as the prior art, the epidemic prevention is emphasized, but the normal work and study life cannot be realized, like the positive protection of nuclear biochemical equipment, and the structural appearance of the epidemic prevention articles influences the use effect of daily work and study life. The infection is prevented, the daily requirements of normal work, study, life, trip and entertainment cannot be met, the shutdown and the stoppage of learning occur, the stability of life is influenced, and the system is particularly more obvious in traffic, transportation, tourism, entertainment, study, sports, commercial service and the like. There are also animal infection, diet infection, epidemic affecting each link and vicious circle. The prior art is not accepted in daily life, contradicts, is only used in the field of epidemic prevention, and other industrial personnel keep a distance to epidemic prevention articles. Historically, people have not paid attention to the safety of the oral and nasal passages until now, air is directly sucked into the lungs, and diseases formed by various bacteria, viruses and dust are many every year. With infectious diseases, most of the infectious diseases are prevented reliably from being isolated from inactive physics, only medicines are used, and thus, the condition and possibility of obviously infecting others inevitably exist.

The epidemic prevention gauze mask that is widely used at present comprises a hanging ring and soft cloth, and although has certain prevention effect in the aspect of preventing dust and germs from being directly inhaled, the main defects of the epidemic prevention gauze mask are as follows: because the mask is tightly attached to the mouth and the nose, the mask has too small breathing area, difficult breathing and very uncomfortable, and the mask is not tightly worn, so that the risk of infection still exists. After the mask is worn for a period of time, the soft cloth is easy to be wet due to the gas generated by the breath of the mouth and the nose, so that dust, bacteria and the like are infected on the surface of the mask, the bacteria are easy to breed, and the harm is caused to the health of personnel.

The common technical characteristics of the prior art are as disclosed in documents CN111249642A, CN305890868 and the like, but the breathing area of the mask is not increased compared with that of a common mask, the air circulation part is generally designed in the front, and the light on the face is shielded to influence the recognition and the beauty, so that the mask, the eye patch, the face mask and the head cover in the prior art cannot reliably prevent epidemic, are difficult to breathe, cannot prevent the disease of air infection, and cannot effectively prevent the defects and the defects of ultraviolet rays, dust, haze and the like.
