Detailed Description
The utility model is further described below with reference to the accompanying drawings.
A multifunctional high-filtration low-air-resistance electret mask capable of generating hydrogen and preventing fog, as shown in figure 1-2, comprises a nose clip 5, a non-woven fabric outer layer 1, a middle layer and a non-woven fabric inner layer 4. The non-woven outer layer 1 is hydrophobic polypropylene spun-bonded non-woven fabric. Non-woven fabrics inlayer 4 includes that two-layer hydrophilic super gentle spunbonded nonwoven and sets up the spherical hydrogen production drier 7 in the middle of two-layer hydrophilic super gentle spunbonded nonwoven, spherical hydrogen production drier 7 is located the middle certain limit of two-layer hydrophilic super gentle spunbonded nonwoven, also can say so set up intermediate layer 6 at non-woven fabrics inlayer 4 (also can be called hydrophilic super gentle spunbonded nonwoven) in the middle of, place the spherical hydrogen production drier 7 that can absorb moisture and produce hydrogen in intermediate layer 6, intermediate layer 6 sets up at the wing of the nose bridge, oral area position. The middle layer comprises a coarse fiber melt-blown cloth layer 2 and a fine fiber antibacterial electret melt-blown cloth layer 3. During manufacturing, the non-woven fabric outer layer 1, the coarse fiber melt-blown fabric layer 2 and the fine fiber antibacterial electret melt-blown fabric layer 3 are made into coils and then are sequentially unreeled, and finally, the non-woven fabric outer layer and the non-woven fabric inner layer 4 are laminated and subjected to sheet beating and spot welding to form the anti-bacterial fabric. Wherein, the nose clip 5 is arranged between the non-woven fabric outer layer 1 and the coarse fiber melt-blown fabric layer 2 and fixed by spot welding. The spherical hydrogen production drying agent is in a shape of a Chinese character kou in the distribution range of the inner layer 4 of the non-woven fabric, and the periphery of the spherical hydrogen production drying agent is welded with the two layers of hydrophilic super-soft spun-bonded non-woven fabrics through hot pressing or ultrasonic welding. Specifically, the distribution range of the spherical hydrogen-producing drying agent in the non-woven fabric inner layer 4 is positioned at the mouth and nose.
Preferably, the non-woven fabric outer layer 1 is a hydrophobic polypropylene layer, which can block moisture (including air droplets) and large particles in the air from the outermost layer of the mask, so that germs using the air droplets and the large particles as carriers can be effectively intercepted and prevented from entering the layer below the mask. The two layers of hydrophilic super-soft spun-bonded non-woven fabrics and the spherical hydrogen production drying agent form a sandwich structure, and the spherical hydrogen production drying agent is limited in a certain area to form a hydrogen absorption layer. The sandwich structure's hydrogen layer of producing hydrogen absorbs water exists with the mouth font at whole hydrophilic super gentle spunbonded nonwoven layer, and the mouth font is all around through hot pressing or ultrasonic bonding, and its effect is fixed together two-layer hydrophilic super gentle spunbonded nonwoven layer, and the tensile effect of two-layer non-woven fabrics restricts the sphere of one deck hydrogen production drier in 1-2cm area scope, forms a layer of producing hydrogen that can absorb water on the whole, and does not make it pile up. Furthermore, the square-mouth-shaped spherical hydrogen production drying agent capable of absorbing water and producing hydrogen is arranged on two sides of the nose bridge of the nose wing and in the mouth area, namely in the position close to the mouth and the nose where the air is likely to be exhaled.
The spherical hydrogen production drying agent is spherical, ellipsoidal or irregular spherical. The spherical hydrogen production drying agent has the grain size of 0.5-2mm, so that the using time of the mask can be prolonged from 4 hours to 12 hours, and the mask is not wetted by expiration and cannot breed bacteria. The super-soft spun-bonded non-woven fabric has the characteristic of keeping a spherical structure after moisture absorption, so that the super-soft spun-bonded non-woven fabric is not subjected to moisture absorption and pulverization and is absorbed into a human body through the mouth and the nose to generate adverse effects.
The spherical hydrogen-producing drying agent is a metal hydride which can produce hydrogen when meeting water, and can be one of calcium hydride, lithium hydride, sodium hydride or sodium borohydride. In this application, spherical hydrogen production drier still contains framework material, including dolomite attapulgite clay, kaolin, bauxite etc. and its through dry 12h backs respectively in the oven, mixes, crocus, granulation, screening with calcium hydride in dry nitrogen atmosphere, forms spherical hydrogen production drier.
The coarse fiber melt-blown cloth layer 2 is polypropylene coarse fibers; the fine fiber antibacterial electret melt-blown cloth layer 3 is polypropylene fine fiber added with an antibacterial agent, and 3-7% of electret master batch is added during manufacturing. Through the effect of charging, make the antibacterial electret of thin fiber melt-blow cloth layer 3 load static and form the state of taking static, it can play the electrostatic adsorption effect to great dust granule and germ granule to catch it. As shown in fig. 3, the initial path of the fine particles is line a, when the fine particles are subjected to electrostatic adsorption, the path of the fine particles is changed to line b due to the downward attraction, the fine particles are adsorbed around the pores of the fine fiber antibacterial electret meltblown layer 3, the middle of the pores is still unobstructed, and therefore the air passing resistance is reduced.
Preferably, the electret masterbatch is succinimide. The charging effect can be realized in two ways: firstly, a corona electret process, namely unreeling melt-blown fabric containing an electret material through electrostatic electret equipment, and attaching charges to the melt-blown non-woven fabric through high-voltage discharge; and secondly, in the water electret process, the melt-blown fabric is unreeled and passes through water electret equipment, the prepared pure water is conveyed to a nozzle by a high-pressure water pump, the passing melt-blown fabric is sprayed by a fan-shaped nozzle, and the two rub to generate static electricity.
Preferably, each mask is individually packed in a PE bag, and vacuum packed or placed in a sachet of a non-toxic, odorless food desiccant to prevent the calcium hydride component from being consumed by moisture contained prior to use.
The working principle of the multifunctional high-filtration low-air-resistance electret mask capable of generating hydrogen and preventing fog is as follows:
when breathing in, the mask body and the space between the mouth and the nose are in a negative pressure state, and the air flow sequentially passes through all layers of the mask from outside to inside to enter a respiratory system of a human body. The non-woven fabric outer layer 1 and the coarse fiber melt-blown cloth layer 2 are used as first-stage filtration for filtering spray and dust of larger particles and partial small particles in the air, and the fine fiber antibacterial electret melt-blown cloth layer 3 is used as second-stage filtration for filtering fine particles and bacteria penetrating through 0.3 micron and finally enters a human body respiratory system through the non-woven fabric inner layer 4.
When exhaling, gauze mask body and oronasal facial space are in the malleation state, and the steam that contains in the expired gas is caught a part by hydrophilic super gentle spunbonded nonwoven fibre, and the remainder passes through intermediate layer 6 along with exhaling, is absorbed completely by the spherical hydrogen production drier who fills in intermediate layer 6 to from producing appropriate amount dry hydrogen, along with breathing in inlet mask body and oronasal facial space, and then get into the human body, the effect of oxygen free radical, ageing resistance is eliminated in hydrogen performance.
After once breathing circulation like this, inspiratory being through filterable clean air many times, the steam of exhalation is absorbed, and the gauze mask inlayer has kept the drying to can not increase the resistance of ventilating of gauze mask, and avoided breeding of bacterium in humid environment, and then the peculiar smell appears when having avoided wearing a period, play extension gauze mask safe use time's effect.
