Active breathing-type mask

Abstract

The invention discloses an active breathing-type mask. The active breathing-type mask comprises a mask main body, a filtering part and a connecting part. The filtering part mainly comprises a cavity, an air blowing fan, replaceable filtering cores, an oxygen content sensor, a PM2.5 content sensor, a signal transmitter, an air guide pipe and a ventilating valve; air inlets of mesh-shaped structures are formed in the two sides of the cavity; each replaceable filtering core is arranged on the outer side of the corresponding structure; the replaceable filtering cores are fixed to the interior of the cavity through mechanical bayonets. The air blowing fan is arranged above the cavity and is communicated with the air guide pipe and the cavity; the air in the cavity is extracted out and is fed into the ventilating valve through the air guide pipe. The ventilating valve is adhered to the inner side of the mask main body through a Velcro; a ventilating through is formed in the ventilating valve. The mask main body of the active breathing-type mask is of an annular design; the pressure on the ears and the neck is low after long-term wearing by matching an upper connecting part and a lower connecting part which are made of an elastic dressing. The filtering part adopts an active gas inlet and split design; stable oxygen content and air cleanliness in the mask main body are ensured through the oxygen content sensor and the PM2.5 content sensor.

Description

technical field [0001] The invention relates to a wearable device, in particular to a breathing mask capable of actively taking in wind. Background technique [0002] Air is an essential substance for human survival, and clean air plays an extremely important role in human health. Oxygen in the air, especially, has the greatest effect on the human body. If the oxygen content is too low or people inhale harmful substances while breathing the air, it will have a great negative effect on the health of the human body, and may even bring life danger. [0003] In an environment with severe air pollution, people generally wear masks to filter pollutants in the air when they go out. The current masks have various styles, but the structure is all made of simple breathable fabrics with elastic stitches, which fit tightly to the face, leaving no room for breathing, and poor air permeability. The shape of the mask changes when inhaling and exhaling , Wearing it for a long time can eas...
