Abstract

The utility model relates to a hidden nose hood, relating to an environmental protection protective article. The utility model relates to the dust-proof and anti-toxic hidden nose hood which is worn by city people for a trip and is suitable for a district with serious air pollution. The purpose is that the hidden nose hood is directly worn in a nostril for preventing dust and poison. The utility model comprises hidden nose hood frames 1, a filter core 2, a frame bridge belt 3 and a fixing clamp 4. The frame bridge belt 3 is communicated with a left and a right frames 1. One filter core 2 is respectively arranged in the frames 1 left and right. The fixing clamp 4 is stuck to the frame bridge belt 3. The utility model has the advantages of beautiful and practical effect and low cost and has no secondary pollution to an environment.

Description

Adelomorphic nose cup

The utility model relates to the environmental-protection articles for use, is applicable to the adelomorphic nose cup of the dust proof and gas defence that the serious area of air pollution and the city public wear when trip.

Because the madness of mankind's activity, especially chimney, vehicle exhaust, chemical plant toxic emission, trash burning and mining area dust etc. cause air by pellet and noxious material severe contamination, cause respiratory disorder and pneumoconiosis to take place frequently.Discover that now contaminated grit enters human body just with surprising rapidity, public health and life-span have been caused great prestige evil.Yet breathing mask in the past is plain, high price and give fear.Therefore, the individual stealth protection product of dust and the bacterium that adheres to, virus and poison gas are essential in institute in the energy filtered air.

The utility model purpose is directly to be worn in the nostril, in order to the adelomorphic nose cup of dust proof and gas defence.

The utility model purpose is achieved in that

A kind of adelomorphic nose cup is characterized in that comprising latent type nose cup framework 1, filter core 2, frame bridge band 3 and geometrical clamp 4; Two frameworks 1 about frame bridge band 3 is communicated with, the filter core 2 of respectively packing into about in the framework 1, geometrical clamp 4 is mounted on the bridge band 3.

In conjunction with the accompanying drawings, further specify the utility model content.

The three-dimensional assembly structure figure of Fig. 1 the utility model.This novel latent type nose cup framework 1, filter core 2, frame bridge band 3 and geometrical clamp 4 of comprising; Two frameworks 1 about frame bridge band 3 is communicated with, the filter core 2 of respectively packing into about in the framework 1, geometrical clamp 4 is mounted on the bridge band 3.

Framework 1 comprises chimney filter 1.1, plum blossom support 1.2, and valve body 1.3 and valve distinguish 1.4; Chimney filter 1.1 is at the center, and plum blossom support 1.2 is enclosed within on the chimney filter 1.1, and going to the bottom of chimney filter 1.1 is valve body 1.3, and valve body 1.3 edges have slim valve to distinguish 1.4.

Framework 1 and bridge band 3 integrated injection moldings mount geometrical clamp 4 then on the bridge band, dress people filter core 2 in framework chimney filter 1.1 can be worn at last.Framework can adopt latex material, the geometrical clamp duroplasts.Frame size has different gauge size according to sales territory ethnic group difference, and the erect image clothes has different size the same.

The nose cup nostril of packing into distinguishes that by valve 1.4 the pressure and the support force of plum blossom support 1.2 are fixed on the nasal septum.Distinguish by filter core 2 and valve and 1.4 close to suck air; Hole by plum blossom support 1.2 and valve distinguish that 1.4 unlatching exhales.Like this, inhaled air must filter through filter core 2, and filter core elimination grit and noxious material are to ensure the purification that sucks air; Distinguish 1.4 unlatching and exhale by the hole and the valve of plum blossom support 1.2, ensure that expiration is unimpeded.

Long fibre elimination grit in the filter core, charcoal absorption poison gas, whether indicating thing mapping filter core lost efficacy.The structure of filter core is seen Fig. 4.

Fig. 2 filter core stereogram.This figure stereogram of filter cartridge construction form 3 that drawn.It comprises at the bottom of plastic cup 2.6 porous cups 2.2, working groove 2.1 and the filter fiber 2.3 (conceal and can't see) of cup at the end.

Fig. 3 the utility model is worn figure.The valve of geometrical clamp 4, the 1.4 expression nose cup frameworks 1 of the 4 expression adelomorphic nose cups that expose in the capitiform is distinguished.The nose cup nostril of packing into distinguishes that by valve 1.4 the pressure and the support force of plum blossom support 1.2 are fixed on the nasal septum.Distinguish by filter core 2 and valve and 1.4 close to suck air; Hole by plum blossom support 1.2 and valve distinguish that 1.4 unlatching exhales.Like this, inhaled air must filter through filter core 2, and filter core elimination grit and noxious material are to ensure the purification that sucks air; Distinguish 1.4 unlatching and exhale by the hole and the valve of plum blossom support 1.2, ensure that expiration is unimpeded.

Filter core 2 comprises filter fiber 2.3, active carbon 2.5 (granular or fibrous), indicating thing 2.4 and filter core plastic casing 2.6; Former three is full of full filter core by various combination, can inhale people's composition granule and poison gas to filter, and the outer cover packaging former three.Wherein filter fiber is by mutual micro-porous permeable, and its tightness degree and pore size thereof are decided by vapour lock and filter effect, filter fiber elimination pellet, and charcoal absorption poison gas, and whether indicating thing mapping filter fiber and active carbon lost efficacy.

Fig. 4 (a) filter cartridge construction form 1

Nonwoven coating active charcoal 2.5 and indicating thing 2.4, extrusion molding then; Nonwoven 2.3 be shell 2.6 be again filter fiber 2.3, when indicating thing (as silicon particle 2.5) is by blue look pink, represent that promptly filter core lost efficacy.

Fig. 4 (b) filter cartridge construction form.

Nonwoven 2.3 at the bottom of putting into glass in the bottom of dixie cup 2.7 earlier reinstalls active carbon 2.5 and indicating thing 2.4 (as silicon particle), builds nonwoven bowl cover 2.3 at last, revolves envelope again.

2.7 plastic cup 2.6 at the bottom of the porous cup, the nonwoven shield 2.3 of packing into reinstalls active carbon and indicating thing, covers nonwoven bowl cover 2.3 at last and revolves envelope again; The V-type groove 2.1 at the cup end is the processing technology groove.

Fig. 4 (d) filter cartridge construction form 4

Adopt the fibroin 2.8 of cigarette filter to make filter fiber, it mixes with NACF 2.5 and indicating thing 2.4 (as silica gel), fastens into cylindric and packs cut-out again with cigarette paper 2.7, just be finished product.Here NACF has the double action of filtration and absorption.

This novel filter core all is the degradable thing except the mode of state 4 (c) structure, environmentally safe; Even the structure of Fig. 4 (c) also can be utilized by reclaiming plastic casing 0.6 again.

Effect: 1, both artistic and practical;

2, cost is low, to the environment non-secondary pollution.
