Description

The nostril air filter

Technical field

The utility model relates to a kind of air filter, particularly a kind of portable nostril air filter.

Background technology

Along with industrialized development; environmental pollution has become a big problem of society; the tail gas that the waste gas of industrial and mining enterprises and all kinds of motor vehicle are discharged; cause that various suspensions and sand and dust day by day increase in the air, in the face of rugged environment, the sand and dust that dust storm is rolled; particularly variously have communicable virus; can only adopt the health treatment that wears masks with this class of dust mask, stop that sand and dust and virus enter respiratory system, the protection people's is healthy.But, therefore cause many people not want to use because they were both inconvenient, not attractive in appearance again in use.People have designed many portable air cleaners for this reason, as a kind of nose cup that patent application 01205500.X provides, are placed in the human body nostril, and its nose cup has skeleton to support, and the inside and outside attachment fiber fabric of skeleton is filled filter substrate in the fabric; A kind of nose cup that patent application 02223440.3 provides comprises the cover body, and the shape of cover body and the shape of nose adapt, and cover body bottom is netted air-permeable layer, and the cover body is provided with a filter course in the bottom.For people live in contaminated air, working provides effective protection.But they in use, and it is convenient inadequately and firm to wear, thereby influence is applied.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved nostril air filter is provided; it wears convenience, firm, and good looking appearance, can effectively filter out harmful substances in air; purify and suck air, the protection people's is healthy.

The purpose of this utility model can realize by following technical measures: this filter comprises a pair of filter block that adapts with nostril front end shape, filter block is linked up by connector, connector is divided into two parts, be separately fixed on two filter blocks, connector is connected as a single entity by hinged, and the hinged place is provided with fastening spring; Between two filter blocks, be provided with two corresponding mutually nasal septums and clamp plush copper.

Filter block comprises the nostril lid that is laid with a plurality of ventilative through holes, is provided with filter course outside lid, and filter course is provided with the thin pad of sponge of good permeability outward.Filter course can be provided with as required, can be made of individual layer, also can be formed by two-layer or MULTILAYER COMPOSITE, and can put into spices or subsidiary disease-treatment and health-care medicine etc. at filter course.

During use, press off the clamping plush copper with finger by connector, plush copper is stretched in the nostril, when cover body is adjacent to the nostril, unclamp finger, at this moment, plush copper is clamped nasal septum, then can.

The utility model is reasonable in design, utilizes elastic force to fix by plush copper, thereby wears conveniently, firmly, does not influence during use and speaks, do not have sultry sensation, it is simple in structure, and is specious, use easy to carryly, good filtration effect is the portable air filter of a Nover practical.

Description of drawings

Fig. 1 is a structure chart of the present utility model.

The specific embodiment

With reference to Fig. 1, this filter comprises a pair of filter block [1] that adapts with nostril front end shape, filter block [1] comprises nostril lid [4], on lid [4] face is last convex, profile and people's nostril is corresponding, lid [4] is laid with a plurality of ventilative through holes [5] from top to bottom, below lid [4], be provided with filter course [6], filter course [6] is made of activated carbon layer and gauze layer, be provided with the thin pad of sponge [7] of good permeability below the filter course [6], the thin pad of sponge [7] periphery is embedded in above the lid [4], and filter course [6] is fixed between lid [4] and the thin pad of sponge [7].

Two filter blocks [1] are linked up by connector [3], and connector [3] is divided into two parts, and the upper end is separately fixed on two lids [4], and connector [3] and lid [4] adopt plastic cement to make, and connector [3] is connected as a single entity by hinged, and the hinged place is provided with fastening spring [8].

Be provided with two corresponding mutually nasal septums and clamp plush copper [2] between two filter blocks [1], plush copper [2] is located at respectively on the inboard, connector [3] upper end, and the spacing between the plush copper [2] is corresponding with septonasal thickness, and during use, plush copper [2] can stretch in the nasal septum; Be respectively equipped with fixture block [9] in the outside of two filter blocks [1], fixture block [9] adapts with the recess of both sides, people's nose outside, may be stuck in both sides, nose outside when wearing.Fastening spring [8] inwardly shrinks two plush coppers [2], produces the pressure that clamps, and when pressing connector [3] both sides, lower end with finger, two plush coppers [2] expansible conveniently takes out and puts into.
