Description

Respiration filtering device

Technical field

The utility model belongs to a kind of health treatment, is specifically related to a kind of device that can filter the air of human body respiration.

Background technology

At present, because going from bad to worse and the continuous discharging of industrial waste gas of atmospheric environment contains a large amount of dust, chemical particle, the grains of sand and virus, bacterium etc. in the daily inhaled air of people, health is caused bigger harm.In order to alleviate above-mentioned harm, people generally wear mouth mask and protect.But use mouth mask to have following shortcoming: the inconvenience of 1, talking, eat; 2, influence facial appearance; 3, wear like a hen on a hot girdle in hot day.

Summary of the invention

The purpose of this utility model is to provide a kind of respiration filtering device, and it is the particulates emission in the filtered air effectively, does not influence daily life and facial appearance again, and comfortable wearing.

Its purpose can realize by following scheme: this respiration filtering device comprises the filtration body of being made by filtering material, is provided with overcoat with the nasal cavity form fit filtering the body periphery, and the front and back of overcoat is provided with air-vent.The front of so-called overcoat is meant when the overcoat plug is in user mode in nasal cavity that near the one side of nasal cavity outside, its relative another side is called the back of overcoat.

Realization above-mentioned purpose scheme preferably is: the tubular that is shaped as that filters body, position is provided with cavity in the middle of it, the aperture position of cavity is near the air-vent of overcoat front, cavity directly is communicated with the air-vent of overcoat front, and and the air-vent of overcoat back between filter body by tubular and separate.

Realize that the better scheme of above-mentioned purpose is: filter between body and the overcoat and have the gap, gap between the two forms the interlayer chamber, the interlayer chamber directly be communicated with the air-vent of overcoat rear end and and separate by tubular filtration body between the air-vent of overcoat front end.

Above-mentioned overcoat can be elastic overcoat.

The utlity model has following advantage and effect:

1, fills in behind the nasal cavity and can suck filtrations such as dust in air, chemical particle, the grains of sand, also can hold back, help protecting user's health sucking in the air most virus, bacterium.

2, the existence of interlayer chamber and cavity can increase the area that sees through of air, make air except can be directly entering the human respiratory tract through the bottom surface of tubular filtering bodies by the air-vent of overcoat front end, also have most of air to enter cavity in addition by the air-vent of overcoat front end, the side that sees through the tubular filtering bodies then arrives the interlayer chamber, air-vent by the overcoat rear end enters the human respiratory tract at last, and it is smooth and easy to guarantee that the user breathes; The interlayer chamber also helps regulating the pressure of overcoat to nasal cavity, if promptly the overcoat size is big than nasal cavity, then after overcoat is filled in the nostril, because the existence in interlayer chamber, make the outer leeway that is with compression, thereby can prevent from nasal cavity is produced excessive pressure, alleviate user's swelling pressure sense.

3, simple in structure, volume is little, and cost is low, and is easy to carry.

4, can be as required in filtering body, add various medicines, with further reinforcement sterilization, health-care effect such as refresh oneself.

5, the utility model is particularly suitable for breathing problem patient use, and bacterium, virus that the air of it can being breathed out contains are held back, and also can further they be eliminated if add medicine in filtering body, prevents to propagate in the air.

The specific embodiment

Fig. 1, Fig. 2, Fig. 3, Fig. 4, respiration filtering device shown in Figure 5 comprise the filtration body of being made by sponge material 1, are provided with overcoat 2 with nasal cavity 7 form fit filtering body 1 periphery, and overcoat 2 adopts the silica gel materials to make, and has elasticity; Air-vent 21 and back air-vent 22 before the front and back of overcoat is respectively equipped with.The front of so-called overcoat, be meant when the respiration filtering device plug is in user mode in nasal cavity, overcoat is near the one side (being the one side at A-A section place among Fig. 2) of nasal cavity outer end, and its relative another side is called the back (being the one side at C-C section place among Fig. 2) of overcoat.Fig. 4, shown in Figure 6, the shape approximation that filters body 1 is cylindric, position is provided with cylindrical hollow chamber 4 in the middle of it, the aperture position of cavity is near the preceding air-vent 21 of overcoat, cavity 4 directly is communicated with the preceding air-vent 21 of overcoat, and separates by cylindric filtration body 1 between the back air-vent 22 of cavity 4 and overcoat.Filter between body 1 and the overcoat 2 and leave the gap, gap between the two forms interlayer chamber 3, and interlayer chamber 3 directly is communicated with the back air-vent 22 of overcoat, is separated by cylindric filtration body 1 between the preceding air-vent 21 of interlayer chamber 3 and overcoat.When using this respiration filtering device, air is except can be directly being entered the human respiratory tract through the bottom surface of tubular filtering bodies (face of E indication among Fig. 6) by the air-vent 21 of overcoat front end, also have most of air to enter cavity 4 by the air-vent 21 of overcoat front end, the side (face of D indication among Fig. 6) that sees through the tubular filtering bodies then arrives interlayer chamber 3, and the air-vent 22 by the overcoat rear end enters the human respiratory tract at last.

Shown in Figure 1, above-mentioned respiration filtering device can use in two pairings, also is provided with the middle connection strap of being made by flexible plastic 5 between two respiration filtering devices.Can prevent that like this one of them from being sucked or being tucked into the nasal cavity deep because of carelessness, be convenient to daily carrying again, connection strap 5 takes out respiration filtering device in the middle of also can utilizing after the use from nasal cavity.Connection strap 5 can adopt transparent material to make in the middle of above-mentioned, and is littler to the influence of wearer's appearance like this.
