Abstract

The invention relates to a portable respirator with potential equilibrium and carbon oxygen exchange which includes a cover, a filtering device and an oxygen supply device. The cover is provided with a sealing ring, an elastomeric headband and a potential balancer. A plurality of fan-shaped filters are stacked in the cavity of the filtering device in a circumferential direction. The oxygen supply device includes a first tank and a second tank. The first tank is provided with a lithium battery, a miniature air pump and a reaction tank. A plurality of radiating copper pipes are circumferentially arranged on the outer wall surface of the first tank. A miniature liquid oxygen tank, an electric pressure reducing valve, a tension spring and an end cap are arranged in the second tank. One end of the miniature liquid oxygen tank is in contact with the end cap by the tension spring. The potential equilibrium and carbon oxygen exchange of the invention has advantages of having reasonable and simple structure, easy to use, small volume, light weight, and portability, etc., which effectively solves the problem of traditional respirators being inconvenient to be carried and used.
