Description

Air supply and ventilation multipurpose protective mask and air supply device

Technical Field

The invention relates to a protective appliance, in particular to an air supply and ventilation multipurpose protective mask and an air supply device.

Background

Masks are common in daily life, except for winter and severe environmental pollution, the masks are used for cold protection, warm keeping, dust prevention and haze prevention, and special or more professional medical masks capable of effectively preventing virus propagation are also provided. When the mask is used, the mask is mainly covered on the face of people to prevent cold wind, dust, harmful air and micro particles or viruses from invading into the body through the oral cavity or the nasal cavity of people, thus being harmful to health. However, the existing dust-haze-preventing and anti-virus mask is basically discarded after being used once, although the mask is worn to cover the majority of the face of a user, the part which really needs to be shielded and protected is only the mouth and nose parts of people, namely, the part of the mask which actually plays a protective role accounts for less than half of the area of the whole mask, and the mask can only be used once and discarded, so that huge waste of resources is caused, and unnecessary economic burden is brought to consumers. Relative gauze mask can only disposable defect, and current multiple protective mask product filters harmful air through advancing exhaust apparatus, prevents dust and prevent wind, and different professional protective mask have different guard action, both can used repeatedly, have stronger protecting effect again, make the consumer have more choices. However, most of the existing protective mask products have the problems of complex structure, inconvenient wearing, single function, limited use, and higher manufacturing cost and sale price, especially various professional protective masks, due to functional design reasons, the mask has strange appearance and shape, is incompatible with the daily life work and the travel environment scene of people and causes the rejection psychology of people, the non-professional work needs and the special scene requirements, and ordinary people do not accept to select the protective mask as a substitute of the mask for daily life work.

Meanwhile, the existing mask or face mask effectively shields harmful gas, substances or germs, has a good protection effect, and simultaneously faces the obvious defects of large air impedance and poor wearing experience.

Aiming at the current situation, the invention innovatively designs the mask-replacement-type external power supply-driven multipurpose protective mask, the ventilation fan drives air to flow, and the air filter disc for protecting the mouth and nose parts is replaced, so that the mask can prevent dust and haze and more effectively and more safely prevent virus from spreading and invading, can also be used for sun-screening, wind-proofing and warm-keeping in daily life, and has the characteristics of multi-scene application and reusability.
