Description

Full cover portable air purifier

The invention relates to a portable air purifier, especially a full-cover type portable air purifier that can be worn on the user's chin and covers the mouth and nose, and can continuously provide filtered clean air into the mask to form positive pressure isolation.

Today's portable air purifiers have pump-type models, such as my country's Patent Announcement M433872 Portable Air Filtration Supply Device Improvement, and M395483 Portable Air Filtration Supply Device, which drives an air pump through a motor to make the air pump pressurized. The filtered air is delivered to the user's mouth and nose. However, the air pump operates in an intermittent manner, so it cannot be used to form an air curtain (air curtain) that blocks bacteria or viruses in front of the user's mouth and nose. For this reason, the inventor of this case once proposed an air purifying protection device (Patent Announcement No. M603765 of the Republic of China), which has a purifying main unit to be worn on the user's chin, and an air guide cover is combined with the air purifying main unit. The host filters the air and sends it to the wind guide, forming an air curtain in front of the user's mouth and nose to prevent dust, PM2.5, bacteria and viruses from passing through, and provide users with clean air to breathe.

However, simply using the air sent by the purifier to the air guide hood makes the wind form an invisible air curtain. In the case of higher protection requirements, the protective effect may be slightly insufficient, and another portable air purifier with more comprehensive protection must be provided. .
