Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1 and 2, the utility model discloses a filter type breathing apparatus, which comprises a casing 10, a filtering mechanism, a gas pipe 30 and an exhaust pipe 40, wherein check valves 42 are arranged at two ends of the exhaust pipe 40, and a pair of scavenging pipes 41 are communicated with the center of the exhaust pipe 40. The size of the shell 10 is close to the size of the mobile power supply, and the shell is suitable for being worn on a user. The inner cavity of the shell 10 is provided with an air pump 11 and a power supply device 12, and in the embodiment, the power supply device 12 is a nickel-metal hydride battery capable of being repeatedly and circularly charged. The suction pump 11, the air pipe 30, the exhaust pipe 40 and the check valve 42 are communicated in sequence. The air pipe 30 is further provided with two sub-air pipes 31, the check valve 42 has a one-way ventilation function, air can only flow out from the center of the exhaust pipe 40 to the two ends of the exhaust pipe 40, and outside air cannot flow into the exhaust pipe 40 through the check valve 42.

The filtering mechanism comprises an inhalation filtering mechanism and an exhalation filtering mechanism, the inhalation filtering mechanism comprises a first filter 20, a second filter 21 and a third filter 22, the first filter 20 is arranged outside the shell 10, and the first filter 20 is communicated with the air inlet of the air pump 11. The second filter 21 is communicated with the air outlet of the air suction pump 11, the air pipe 30 connects the second filter 21 with the third filter 22, and the air pipe 30 is branched at the position of the third filter 22 through the sub-air pipe 31. The expiratory filter mechanism comprises a fourth filter 23, the fourth filter 23 being provided at the exhaust end of the check valve 42. The number of the expiratory filter mechanisms is two, and the expiratory filter mechanisms are symmetrically arranged at the left side and the right side of the exhaust pipe 40 by the vertical middle line of the exhaust pipe 40.

In this embodiment, the first filter 20 and the fourth filter 23 are both air particulate filter elements. Air particulate filter element the filter had a glass fiber filter media with an average fiber diameter of 0.5 microns. When the size of the harmful particles is larger than the average pore size of the filter medium (about 0.1 μm), the harmful particles directly collide with the surface of the fiber matrix of the filter for the purpose of intercepting the particles. And if the harmful particles and the charge on the filter can form a large enough electrostatic attraction force to attract the harmful particles to the surface of the filter, the particles can be deposited by means of electrostatic deposition, and the static electricity has the effect of assisting in intercepting the particles.

In this embodiment, the second filter 21 is a filter capable of storing liquid, and stores a liquid capable of sterilization, such as physiological saline, to sterilize and disinfect the air drawn in by the suction pump 11 and then feed the air into the sub-air tube 31. Since the air passing through the second filter 21 is humid, the third filter 22 is a dry filter, and the air entering from the sub-air tube 31 is dried by a substance having high adsorptivity such as activated carbon, thereby preventing moisture from being sucked into the nostrils.

The utility model discloses a use-way does:

(1) turning on a power switch 13 on the surface of the casing 10, the power supply 12 activates the suction pump 11 to start suction, and air enters the casing 10 from the first filter 20;

(2) after the air is sent into the air pipe 30 by the air pump 11, the air passes through the second filter 21 for secondary liquid filtration and then flows into the third filter 22 for drying;

(3) the air exchange tube 41 is plugged into the nostril, the material of the air exchange tube 41 is elastic silica gel, and the gap of the nostril can be completely filled to avoid air leakage; when air is inhaled, after the air is sent into the exhaust pipe 40 from the sub-air pipe 31, the air flows into the nostrils and the two ends of the exhaust pipe 40 from the ventilating pipe 41 respectively;

(4) when air is exhaled, the exhaled air flows into the exhaust pipe 40 from the ventilation pipe 41, because the sub-air pipe 31 keeps supplying air all the time, under the condition of pressure, the exhaled waste gas is conveyed to both ends of the exhaust pipe 40 along with the gas flowing into the exhaust pipe 40 from the sub-air pipe 31, and finally is filtered by the fourth filter 23 at the ventilation end of the check valve 42, purified into clean carbon dioxide gas and discharged to the outside, so that pollution to the outside is avoided.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
