Description

A kind of daily multifunction invisible rhinobyon

Technical field

The present invention relates to a kind of daily protective articles, refer in particular to a kind of the have pernicious gases such as absorption and degraded benzene in air, the daily multifunction invisible rhinobyon of fine dust effect in filtered air.

Background technology

People's inevasible meeting in daily life and work touches the air that some contain fine dust and pernicious gas, for this problem, traditional method is to take to wear mouth mask to carry out the pollutant in filtering gas, yet the mouth mask area is larger, profile is not attractive in appearance, affect talk between people and exchange, long-time use can cause the problems such as breathing has some setbacks, therefore people have designed the nose respiration filtering device of form various kinds, as publication number: 102805904A, 102107050A, the relevant design of 101721777A and 102974017A, yet correlation technique still is difficult to realize the effective filtration to pernicious gases such as benzene at present.

Summary of the invention

For above deficiency; the invention provides fine dust and pernicious gas in a kind of effectively filtered air; have the daily protection rhinobyon that waits various functions stealthy attractive in appearance concurrently; described daily protection rhinobyon is by connecting line, fixed cover (thick ~ 0.5mm); protective layer (thick ~ 1mm); photocatalysis layer (thick ~ 0.6mm); absorption separation layer (thick ~ 1.5mm) and cushion (thick ~ 6mm) form; protective layer; photocatalysis layer; absorption separation layer and cushion are fixed in fixed cover from top to bottom successively, and are connected and fixed by connecting line, as Fig. 1.

Correlation function of the present invention is achieved through the following technical solutions.

Described connecting line selects the transparent PP material to make, and except the effect of playing two nasal obstruction covers of link, has stealthy, attractive in appearance characteristics.

Fixed cover increases comfortable wearing degree and nasal cavity and nasal obstruction frictional force except have to fix each functional layer effect to play simultaneously, the effect of the landing that prevents from having a stuffy nose, and this function is mainly by selecting the soft silica gel material similar to the human body skin pliability to realize.

Protective layer can guarantee good ventilation and logical light effect when playing the protection photocatalysis layer, and it adopts the transparent plastic of the PP material with some micropores to realize, the micropore area accounts for the 50%-60% of the protective layer gross area, and the aperture of micropore is at the 1-3 micron.

Photocatalysis layer mainly is conceived to the photocatalytic degradation to pernicious gases such as benzene; For realizing this function, in the present invention, the design of this layer be take and hanged down wind-resistant activated carbon fiber cloth as substrate, adopts the Ti of hydro-thermal method growth in situ some _1-xfe _xo ₂(x=0.01-0.05) scheme of nanobelt; TiO ₂be a kind of oxide that human-body safety is had no side effect, it can realize the catalytic degradation effect to pernicious gases such as benzene under certain frequency light irradiates, and the introducing of appropriate ferro element can be at TiO ₂forbidden band in introduce the impurity energy level of some, and then can effectively strengthen TiO ₂in visible-range to the catalytic degradation efficiency of pernicious gas, the Ti of nanobelt structure _1-xfe _xo ₂it is large that material (9) has specific area, and the photocatalytic activity high can effectively improve its catalytic efficiency to pernicious gas; In addition select growth in situ Ti in the design _1-xfe _xo ₂nanobelt (9) but not simple load Ti _1-xfe _xo ₂nano-powder or nano wire, can effectively avoid in respiratory nano-powder to suck lung and the safety issue that causes.

Take that to hang down wind-resistant activated carbon fiber cloth (windage ~ 90Pa) be substrate, adopt the Ti of hydro-thermal method growth in situ some _1-xfe _xo ₂the concrete preparation method of nanobelt is as follows: (1) is by TiCl ₄be dissolved in ethylene glycol TiCl ₄with the volume ratio of ethylene glycol be 1:800, cover the preservative film magnetic agitation to evenly; (2) ammoniacal liquor that is 25% by mass percent slowly is added drop-wise in above mixed solution, ammoniacal liquor and TiCl ₄volume ratio be: 20:1, stir and to make it even; (3) by appropriate Fe (NO ₃) ₃9H ₂o adds in above-mentioned mixed solution, Fe (NO ₃) ₃9H ₂o and TiCl ₄quality and volume ratio be: 0.001-0.003:1, stir to form settled solution; (4) above-mentioned solution is proceeded in hydrothermal reaction kettle; The low wind-resistant activated carbon fiber cloth that will blow off fine hair through ear washing bulb joins in reactor; 150 ℃/12 h hydrothermal treatment consists; (5) take out and deposited doped Ti O ₂low wind-resistant activated carbon fiber cloth, successively with deionized water and alcohol, repeatedly rinse; (6) by sample in air 350 ℃ of sintering 2 h to obtain target sample.

The absorption separation layer has micronic dust and not by the function of the pernicious gas of efficient light catalytic decomposition in absorption and air-isolation, in the present invention, this layer is mainly to select low wind-resistant activated carbon fiber felt, the low wind-resistant activated carbon fiber felt that the model that for example the clean charcoal fiber of Jiangsu section Co., Ltd produces is KJFD1300, NACF contains highly developed microcellular structure, have that specific area is large, the adsorption desorption capacity is high, adsorption desorption speed is fast, good purification, can the airborne NO of adsorption filtration ₂reach the pernicious gases such as stench, poison gas, flue gas; To organic gas adsorbance than granular active carbon large several times to tens times; Fine dust, microorganism and bacterium are had to good adsorption capacity.

Cushion is selected aseptic sponge material to play and is avoided active carbon fiber felt directly to contact with skin, increase the effect of using this nasal obstruction comfort level.

This nasal obstruction adopts the sandwich structure design that simply can insert nasal cavity, makes nasal obstruction have stealth, characteristics attractive in appearance concurrently when realizing correlation function.

the accompanying drawing explanation:

Fig. 1 is institute's invention multifunction invisible rhinobyon sectional view;

The microstructure schematic diagram that Fig. 2 is photocatalysis layer, in figure, 8 and 9 are respectively active carbon fibre peacekeeping Ti _1-xfe _xo ₂nanobelt.

The specific embodiment

As shown in Figure 1, the present invention includes 21 and connecting lines of nasal obstruction cover 7 that can directly insert in nasal cavity forms, the nasal obstruction cover adopts simple sandwich structure, be followed successively by fixed cover 2, protective layer 3, photocatalysis layer 4, absorption separation layer 5 and cushion 6, protective layer is selected the transparent PP plastic material with some micropores; Photocatalysis layer adopts growth in situ Ti on active carbon fiber fabrics 8 _1-xfe _xo ₂the method of nanobelt 9 (hydro-thermal method) realizes utilizing the pernicious gases such as visible light efficient degraded benzene; Absorption separation layer 5 selects active carbon fiber felt to realize to the filtration of dust particale in air with to benzene, formaldehyde, NO ₂physical absorption Deng pernicious gas; Cushion 6 is selected senior aseptic sponge, can significantly increase the comfort level of using this product; When actual assembled, can select the protective layer 3 of suitable diameter according to the requirement of actual nasal cavity size, photocatalysis layer 4, absorption separation layer 5 and cushion 6, be arranged in fixed cover 2 successively, re-uses connecting line 7 and fix successively each layer.
