Abstract

The utility model relates to a dust proof nose cover for preventing dust or powder dust from inhaling in the nose. The utility model is characterized in that the utility model has a pair of frames from left to right which are manufactured by the elastomeric materials, and the frames can accordance with human's nostrils and can shade nostrils. The utility model is provided with a holding piece which is connected with the pair of frames and holds the frames on the nasal part. The pairs of frames at least are respectively coated a layer of filtering medium for filtering dust or powder dust, such as fibre fabric, filter net, etc. The utility model can replace common mouthpiece, having higher superiority.

Description

Dust proof nose cover

The utility model relates to a kind of dust or dust of preventing and suck the respiratory protection articles for use in the nose.

Dust is a kind of common form of air-polluting, and in light textile, mining, grain processing, in many industries such as environmental sanitation operation, the dust of various multi-form and compositions, dust, fiber etc. are particularly serious to the pollution of working environment in the air, can greatly influence health.Protective articles to this most normal use at present is cotton yarn mouth mask and dust cover, though to be masked area big that effectively usable floor area is little for its disadvantage, only in the small size scope that is positioned at nose and mouth filter dirt dustproof effect is arranged.Its result not only cause waste of material and also because of to mask face or head than large tracts of land, tangible discomfort is arranged under hot season or hot environment, be difficult for being accepted, thereby also influenced effective use of this class protective articles.

The purpose of this utility model is to provide a kind of anti-dust nose mask with same safeguard function and small volume and less weight at above-mentioned situation.

The utility model anti-dust nose mask structurally has and a pair ofly can adapt with people's two nostrils and can mask the left and right sides framework in two nostrils and with this framework is linked and can make it be held in the holder of nose.Framework can be made by flexible metal or macromolecular material, and should be coated with one deck on it at least respectively has the filter medium that stops with filtration to dust or dust, as fabric, foamed material, filter screen etc.If select filter screen for use, according to the needs of environment for use, its filter opening density can be selected in 100-200 order scope.These filter mediums can be nonvolatil with combining of framework, also can be the detachable form of changing.Holder be held on when using the one-sided of nose or bilateral wing of nose position still be held on two internarial in every the difference at position, it can be different to connecting mode on the framework and position at this.The structural shape of holder is the simplest with U type card structure, and is also easy to use.

Divide from occupation mode, the anti-dust nose mask of the utility model said structure can have hidden and exposure formula etc. multi-form.The former in use the nose cup framework of both sides can be embedded into slightly within the plane, nostril, be characterized in that structure is small and exquisite and influence facial image appearance when using hardly.Then be that cover cap is outside the plane, nostril when the latter uses, be characterized in being easy to according to using needs to change version, for example identical or different multiple layer filter media can be set, or fixed and movable filtering medium layer can be set simultaneously, in order to changing or the plus-minus filter media material.

Below specifically introduce anti-dust nose mask of the present utility model by example shown in the drawings, but scope of the present utility model is not limited in following example.

Fig. 1 hidden anti-dust nose mask

Fig. 2 exposes the formula anti-dust nose mask

In the anti-dust nose mask of Fig. 1, a pair of circular frame of being made by elastomeric material 1 is arranged, about two frameworks be connected in the opening two ends of a U type retaining wedge 3 respectively.Be coated with one deck silk weaving filter screen 2 on two frameworks 1 respectively as filter medium, its filter opening density can be selected for use in 100-200 order scope.During use retaining wedge 3 is sandwiched in two internarial in every portion, the nose cup of both sides can be embedded within the plane, 1 liang of nostril, has guaranteed several no changes of facial appearance.

In the structure of Fig. 2, this of formation both sides nose cup is double-decker to framework 1.Its at the middle and upper levels framework for can upwards turning up the form of suitable angle along the centre joint therebetween.Two-layer up and down framework all is coated with silk weaving filter screen 2.The upper strata framework can be upwards turned up when needing, the suitable filtering material interlayer that adds can be put into or take out very easily, as fibrous material, foamed material etc.U type retaining wedge 3 links with the joint portion of 1 of the bottom of bent intermediate and left and right sides framework.Clamp method during use is with above-mentioned hidden anti-dust nose mask, and the nose cup of both sides difference cover cap is outside plane, nostril, both sides, so be exposure formula anti-dust nose mask when only being to use.The anti-dust nose mask of this kind structure is particularly suitable for using in the big environment of Dust Capacity.
