Abstract
The utility model provides a dust proof nasal tampon comprising a nasal clamp which is respectively connected with the cylinder nose inserting machine A and B, wherein, the nose inserting machine A consists a tampon cylinder which is internally fixed with a filtering core, the filtering core is provided with an air hole, and one end of the filtering core bottom is connected with a flexible piece which is in corresponding with the air hole and realizes contact with the air hole, the nose inserting machine B has the same structure as the nose inserting machine A. The utility model can solve the problem that the current technique has cockamamie wearing operation, not perfectly smooth breath air flow and not quite satisfactory dust proof effect.
Description
Technical field
The utility model relates to dustproof apparatus technical field.
Background technology
At present, compare under the condition of severe at some environment, people mostly use traditional mouth mask to prevent that dust is inhaled in the body.But there is the problem that complex operation, respiratory air flow are not really unobstructed, the blocks dust effect is not very good of wearing in use in traditional mouth mask.
Summary of the invention
The utility model provides a kind of dustproof nose plug, and it can solve wearing that prior art exists, and complex operation, respiratory air flow are very not unobstructed, the not very good problem of blocks dust effect.
The purpose of this utility model is achieved through the following technical solutions: dustproof nose plug, it has nose clip, connect slotting nose device A, the B that is tubular on the nose clip respectively, insert nose device A and comprise the plug tube, in the plug tube filter core is installed, passage is set on the filter core, filter core bottom one end connects flexure strip, flexure strip and contact corresponding with passage, it is identical with slotting nose device A structure to insert nose device B.
For further realizing the purpose of this utility model, also can finish by the following technical programs: the top of plug tube connects filter screen.The bottom of plug tube connects barrier.Barrier is a circular shape.
The beneficial effect that the utility model can produce: because of it changes the version of traditional mouth mask, adopt nose clip that two plug tubes are connected, the filter core that has passage is installed in the plug tube, flexure strip and passage that one end is connected with filter core are corresponding, people wear the back when air-breathing, flexure strip is closed passage under suction function, and air is inhaled into behind filter element filtering; People are when exhaling, and flexure strip is opened passage under positive pressure, and air-flow is discharged from passage, so that it is worn is simple to operate, respiratory air flow is unobstructed, blocks dust is effective.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Dustproof nose plug of the present utility model, it has nose clip 1, connect slotting nose device A, the B that is tubular on the nose clip 1 respectively, insert nose device A and comprise plug tube 2, in the plug tube 2 filter core 3 is installed, passage 5 is set on the filter core 3, filter core 3 bottoms one end connects flexure strip 6, flexure strip 6 and passage 5 corresponding and contacts, it is identical with slotting nose device A structure to insert nose device B.The top of plug tube 2 connects filter screen 4.The bottom of plug tube 2 connects barrier 7.Barrier 7 is a circular shape.
During making, get final product by the above-mentioned requirements assembling.During use, hand-held nose clip 1 is clipped between two nostrils of nose, and makes slotting nose device A, B insert respectively in two nostrils and get final product respectively.People are when air-breathing, and flexure strip 6 is closed passage 5 under suction function, and air is inhaled into after filter core 3 filters; When exhaling, flexure strip 6 is opened passage 5 under positive pressure, and air-flow is discharged from passage 5.
The technology that the utility model is not described in detail partly is known technology.
