DETAILED DESCRIPTION

[0023] The invention is illustrated in accordance with figures. The figures as simplified diagrams demonstrate the basic structures of the apparatus of embodiments of the invention. Thus, the invention is not limited to the figures.

[0024] As shown in FIGS. 1, 2 and 3, a portable respirator with potential equilibrium and carbon oxygen exchange includes a cover 1 adapted to the shape of a nose and mouth, a filtering device 2 and an oxygen supply device 3. The cover 1 is fixedly arranged with a sealing ring 11. An elastomeric headband 13 is disposed on the connecting piece 12 that is symmetrically arranged on the cover 1. A potential balancer 14 for balancing the potential of the human body is arranged on the cover 1. One end of the potential balancer 14 is electrically connected with the electrode 15 arranged in the inner cavity of the cover 1. The other end of the potential balancer 14 is grounded through a wire, and the electrodes 15 are in contact with the human body.

[0025] The filtering device 2 is a hollow cylinder structure communicated with the cover 1. A plurality of fan-shaped filters 21 are stacked in the cavity of the filtering device 2 in a circumferential direction. The fan-shaped filter 21 is coated with activated carbon impregnated with an antivirus agent. The fan-shaped filter 21 is pressed to be fixed by a post rod 22 in the axis of the cylinder.

[0026] The oxygen supply device 3 includes a first tank 31 that recovers carbon dioxide to produce oxygen and a second tank 32. One end of the first tank 31 and one end of the second tank 32 are respectively hinged with the cover 1. The first tank 31 is provided with a lithium battery 311, a miniature air pump 312 and a reaction tank 314 filled with hydrogen peroxide powder. One end of the miniature air pump 312 is interconnected with the inner cavity of the cover 1. The other end of the miniature air pump 312 is penetrated into the reaction tank 314 through an air guide tube 313. The reaction tank 314 is provided with an outlet pipe 315 that is interconnected with the inner cavity of the cover 1. The outlet pipe 315 is connected with a serial of filter boxes 318 filled with activated carbon. A plurality of radiating copper pipes 319 are circumferentially arranged on the outer wall surface of the first tank 31.

[0027] A miniature liquid oxygen tank 321, an electric pressure reducing valve 322, a tension spring 323 and an end cap 324 are arranged in the second tank 32. One end of the miniature liquid oxygen tank 321 is in contact with the end cap 324 by the tension spring 323. The other end of the miniature liquid oxygen tank 321 is connected to the inlet of the electric pressure reducing valve 322. The outlet of the electric pressure reducing valve 322 is connected with the inner cavity of the cover 1.

[0028] The cover 1 is made of aluminum alloy. The cover 1 is provided with glass fiber cloth for heat insulation. The connecting piece 12 and the cover 1 are integrated. The sealing ring 11 is made of silica gel with a hollow structure, and the cavity is filled with gas. A plurality of through holes 316 are arranged on the wall of the air guide tube 313. The first tank 31 is provided with a switch 317 for controlling the external power supply of the lithium battery 311. Both surfaces of the hollow cylinder structure are made of a mesh plate. The lithium battery 311 is respectively electrically connected with the miniature air pump 312 and the electric pressure reducing valve 322. The lithium battery 311 is provided with a charging and discharging control circuit 3111 with a USB charging port.

[0029] The portable respirator with potential equilibrium and carbon oxygen exchange of the invention includes a cover adapted to the shape of a nose and mouth, a filtering device and an oxygen supply device. The cover is provided with a hollow sealing ring made of silica gel. The sealing ring is filled with gas to make the sealing ability stronger while reducing the constriction to users. The cover is provided glass fiber cloth with effective heat which prevents users from being burnt. The cover is also provided with a potential balancer for removing the potential difference to prevent the static electricity from causing fire. A plurality of fan-shaped filters are stacked in the cavity of the filtering device in a circumferential direction. When the pressure inside the cover is in a positive pressure state, the filter is pushed out to discharge the hot air. When the pressure inside the cover is in a negative pressure state, the filter is closed and is in the stage of filtration. Doing so can maintain the filtration efficiency and reduce the temperature in the cover. The oxygen supply device includes a first tank and a second tank. The first tank draws carbon dioxide gas from the cover into the reaction tank such that oxygen is produced. The second tank is provided with liquid oxygen to ensure the normal use of the respirator when the first tank cannot meet the oxygen supply. The first tank is provided with a switch that controls switch-on and switch-off of the respirator. It is convenient to use. It 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.
