Abstract
The utility model belongs to a respiratory dust-proof device, comprising two cover-shaped stoppers whose outer diameter is matched with nostrils. The upper part of each cover-shaped stopper forms a semi-sphere shape, and the lower part of the cover-shaped stopper is open; the cover-shaped stoppers are fully distributed with through holes, and flexible ventilating filter medium is padded inside each cover-shaped stopper; the through holes are made into meshed holes for increasing ventilating quantity, and the cover-shaped stopper also forms a mesh shape; the flexible ventilating filter medium can be made of compact fabric, such as nylon yarn, filament yarn or non-woven cloth, and the two cover-shaped stoppers are fixed together at the bottom by a connecting plate. The utility model has the advantages of low cost, favorable face perspiration property, and convenient and comfortable operation.
Description
The utility model belongs to breathes dust-proof nasal obstruction.
Breathing main is by the nostril, and dustproof mainly is to prevent that dust from entering the nostril.No matter and existing breathing dust-proof nasal obstruction is face shield, filter mantle or mouth mask, all be that filter dirt area is much larger than two nostril areas.To cover sealing around nose, the mouth or face be covered for dustproof, the inconvenience perspire, especially at the bottom of the coal mine, the operator of big, the air flow property difference of dust, because perspire is poor, be with uncomfortable, be with and just wanted in one or two hour to remove, and cost height, particularly face shield, filter mantle complex structure cost are higher.
The purpose of this utility model provides a kind of easy to use, simple in structure, breathing dust-proof nasal obstruction of being convenient to facial perspire.
The utility model is to speak seldom in the dust place of working by the nostril according to breathing mainly, makes and can see through the hood-shaped plug that filter medium is housed that air can block dust again, and plug is in the nostril.In order to realize the purpose of this utility model, the utility model is taked following structure, and it comprises the hood-shaped plug that two overall diameters and nostril match, the top of hood-shaped plug is hemisphere face shape, the lower open of hood-shaped plug, hood-shaped plug is covered with through hole, the flexible air-permeative filter medium of pad one deck in each hood-shaped plug.Be made as mesh for increasing the said through hole of Air permenbility, said hood-shaped plug is netted hood-shaped plug; Flexible air-permeative filter medium can be a material with densified fabric such as nylon yarn, gauze or nonwoven, available plane or hull shape; Available connecting plate is fixed as one from the bottom two hood-shaped plugs between the two hood-shaped plugs, and the distance between the two hood-shaped plugs is suitable with the distance between two nostrils, and can fix the pinch plate vertical with connecting plate under connecting plate.
Because the utility model is taked said structure, dustproof in the time of in the nostril, just breathing two hood-shaped plug plugs that filter medium is housed, easy to use, simple in structure, be convenient to facial perspire use comfortable, cost is low, better with netted hood-shaped plug gas permeability, elasticity, stop up with two or three hours dust and only to change two flexible air-permeative filter media behind the flexible air-permeative filter medium holes and just can continue to use, user's processes expend is low.With connecting plate with pinch plate and be convenient to dress plug.
Detailed structure of the present utility model is provided by embodiment and accompanying drawing thereof.
Fig. 1 is the vertical view of most preferred embodiment of the present utility model.
Fig. 2 is the front view of most preferred embodiment of the present utility model, and left part is cut open along the A--A line among Fig. 1 among the figure.
Fig. 3 is the expansion plane of the flexible air-permeative filter medium on plane.
Fig. 4 is the side sectional view of the flexible air-permeative filter medium of hull shape.Among the above-mentioned figure:
1, hood-shaped plug 2, through hole 3, flexible air-permeative filter medium
4, connecting plate 5 is pinched plate 6, the flexible air-permeative filter medium of hull shape
Best implement just to see Fig. 1, Fig. 2 of the present utility model, the hood-shaped plug 1 that it has two overall diameters and nostril to match, the top of hood-shaped plug 1 is hemisphere face shape, the lower open of hood-shaped plug 1, hood-shaped plug is covered with through hole 2, the flexible air-permeative filter medium 3 of pad one deck in each hood-shaped plug 1.The through hole 2 of present embodiment is a mesh, and hood-shaped plug 1 is netted hood-shaped plug; Be fixed as one from the bottom two hood-shaped plugs 1 with connecting plate 4 between two hood-shaped plugs 1 of present embodiment, the distance between the two hood-shaped plugs is suitable with the distance between two nostrils, and under connecting plate fixing vertical with the connecting plate plate 5 of pinching.
The expanded view of the flexible air-permeative filter medium 3 on plane is seen Fig. 3, and the flexible air-permeative filter medium of hull shape is seen Fig. 4, and the material of flexible air-permeative filter medium can be used densified fabric such as nylon yarn, gauze or nonwoven.
