Abstract

The utility model relates to a nasal breathing filter, and belongs to human health protective devices. As is shown in the attached map, the nasal breathing filter comprises a filter body 1, catheters 2, nose plugs 3, a support 4 and an elastic cord 5. As is shown in the attached map, the filter body 1 is in a cystic shape, and one surface layer of the filter body 1 is replaceable filtering materials. The worn filter body can be placed behind the neck or in front of the chest of a wearer, and the two ends of the filter body are connected with the two soft catheters. The other ends of the two catheters are connected with the two cone-pipe-shaped nose plugs. The two nose plugs are connected through the support. The two ends of the support are connected with the elastic cord used for covering the position above the ears on the back of the head of the wearer to fix the two nose plugs. By means of the structure, when the wearer breathes, the air in the environment is absorbed into the cystic filter body, and the filtered air enters the nose of the wearer sequentially through the two catheters on the two sides and the two nose plugs.

Description

The nose breathing circuit filter

Technical field

The utility model relates to a kind of nose breathing circuit filter, is mainly used in the operator in dust polluting environment, and the operator is healthy with protection.

Background technology

At present the Protection Product (mouth mask) worn of operator is not tight with the cheek laminating of wing of nose both sides, even on mouth mask, be designed with the device such as bridge of the nose metal clip, effect is still undesirable, and dust still can be sucked by the operator from wing of nose both sides.The at present structure qualification of mouth mask its filter area, also just affected filtering accuracy (size of eyelet and quantity).The mouth mask of pattern easily causes people with glasses's blurred vision at present, because the gas of breathing out out is flushed to glasses from wing of nose both sides, forms one deck mist.

The utility model content

The purpose of this utility model is to provide a kind of health of human body protector, and it can allow the air of wearer's inspiration all through filter, filter, and there is no the gas leakage of slit source ash.Filtering accuracy easily guarantees.The eyeglass wearer sight line is unaffected.

The purpose of this utility model reaches by the following technical programs structural shape and realizes.

A kind of nose breathing circuit filter described in the utility model, mainly contain five parts and form, be i.e. filter, conduit, nasal obstruction, support and elastic cord.Cryptomere filter two ends are communicated with two conduits, and two nasal obstructions are equipped with in the termination of these two conduits, and have support to fix the relative position of two nasal obstructions, elastic cord are housed in order on the head that is fixed on the wearer on support.

The accompanying drawing explanation

Nose described in the utility model mainly comprises five kinds of assemblies with breathing circuit filter, as shown in drawings, and 1-filter, 2-conduit, 3-nasal obstruction, 4-support, 5-elastic cord.

Accompanying drawing is the related nose of the utility model breathing circuit filter overall structure principle schematic, the generalized section of each numeral five kinds of assemblies that refer on figure, be respectively: the 1st, the filter assemblies generalized section, the 2nd, the conduit tube component generalized section, the 3rd, nasal obstruction assembly generalized section, the 4th, bracket component generalized section, the 5th, elastic cord assembly generalized section.

The specific embodiment

1-filter integral body shown in figure is cryptomere, and surperficial one deck is to be covered with the filtering material that meets filtering accuracy size eyelet, and this layer filtering material can be changed separately.The size that guarantees the assorted lower definite eyelet of bar of filtering accuracy determines that according to inspiratory capacity and pressure eyelet quantity can determine filter area again, and then can determine the size of this bag type filter.Wear after-filter and can be in wearer's neck rear or front.The filter two ends are connected with two soft conduits.These two conduit other ends are connected with two nasal obstructions, and these two nasal obstructions are Taper Pipe shapes, and injecting nostril can fit tightly.Two nasal obstructions are connected by a support, make the distance in the suitable wearer of distance two nostrils of two nasal obstructions.The support two ends connect an elastic cord, and this root elastic cord is used for being set to wearer's back of head ear top, to fix two nasal obstructions.

By above-mentioned structure, during wearer breathes, the air in environment is sucked into bag type filter, through two conduits of filtered air via both sides, through two nasal obstructions, enters in wearer's nose again.Oral area can need to be worn the Simple mask of normal style according to specific works in addition.

Claims

1. a kind of nose breathing circuit filter described in the utility model, mainly containing five parts forms, be filter, conduit, nasal obstruction, support and elastic cord, cryptomere filter two ends are communicated with two conduits, two nasal obstructions are equipped with in the termination of these two conduits, and have support to fix the relative position of two nasal obstructions, elastic cord is housed in order on the head that is fixed on the wearer on support.

2. nose breathing circuit filter according to claim 1, is characterized in that the filter shape as one of primary clustering is the capsule formula.

3. filter according to claim 2, is characterized in that the filtering material of filter surfaces can be changed.

4. nose breathing circuit filter according to claim 1, is characterized in that the nasal obstruction as assembly is the Taper Pipe shape.

5. nose breathing circuit filter according to claim 1, is characterized in that only two nasal obstructions to be inserted to the wearer nostril, and after bag type filter was placed on brain, elastic cord was fixed on head.

6. nose breathing circuit filter according to claim 1, is characterized in that nasal obstruction is closely air tight with the nostril laminating.
