Description

A kind of mask with detection and filtering function

[technical field]

The utility model relates to a kind of daily life mask, especially a kind of mask with detection and filtering function.

[background technique]

Mask is a kind of basic protective articles, is often used in daily life, mainly crosses air filtering by mask In suspended matter, achieve the purpose that have a breath of fresh air, as present air pollution is increasingly severe, many cities all occur Haze phenomenon, the arch-criminal of haze are PM2.5, and PM2.5 is the particulate matter that particle diameter is less than or equal to 2.5 microns in atmosphere, this Kind particle enters the lung of human body by breathing, has biggish injury to human body, also occurs PM2.5 mask on the market, still Existing PM2.5 mask has the shortcomings that certain, is non-woven fabrics or fusion spray cloth Filter membrane mask first to the fine particle in air Filter effect is unobvious；The filter membrane mask being followed by made into using fiber or cotton, general gas permeability is poor, and comfort is not It is good；Using mask made of active carbon filter membrane, active carbon and is not filtered to small particle for adsorbed gas Effect；The furniture also for some newly-decorated houses or just bought, can all have formaldehyde, and formaldehyde will also result in very human body Big damage, therefore it is badly in need of a kind of mask that can effectively filter PM2.5 and formaldehyde gas on the market, to facilitate people to make With.

[utility model content]

The technical issues of the utility model solves: for the problems in background technique, the utility model designs one kind can PM2.5 concentration and concentration of formaldehyde are detected, and can show respective concentration value, to the mask that PM2.5 and formaldehyde effectively filter, is supplied People use, and reduce air pollutants and injure to caused by people.

The utility model is achieved through the following technical solutions:

A kind of mask with detection and filtering function, including mask body 1 and elastic ear band 2, it is characterised in that: described Mask body 1 is successively outer layer 3, middle layer 4 and internal layer 5 from outside to inside, and the middle layer 4 is successively that active carbon is inhaled from outside to inside Attached layer 6, nanometer titanium dioxide composite material layer 7 and HEPA filter layer 8, the outside of the outer layer 3 are provided with PM2.5 concentration sensing Device 1, formaldehyde gas sensor 1, display 11 and alarm 12, the PM2.5 concentration sensor 1 and formaldehyde gas The distribution of sensor 1 is arranged in surrounding, and the display 11 is arranged among the outside of outer layer 3 on the lower, the alarm 12 In the side of display 11, the outer layer 3 is internally provided with power supply 13 and single-chip microcontroller 14, and the outside of the internal layer 5 is provided with PM2.5 concentration sensor 2 15 and formaldehyde gas sensor 2 16, the PM2.5 concentration sensor 1, formaldehyde gas sensor One 10, PM2.5 concentration sensor 2 15 and formaldehyde gas sensor 2 16 are connected with the input terminal of single-chip microcontroller 14 respectively, the list The output end of piece machine 14 is connected with display 11 and alarm 12, and the single-chip microcontroller 14 is connected with power supply 13.

Further, the outer layer 3 of the mask body 1 uses bamboo fibre surface layer, and bamboo fibre has natural antibacterial, suppression The effect of bacterium, uvioresistant, deodorization, product made of bamboo fibre can natural degradation in the soil, to environment without any after decomposition Pollution is a kind of natural, green, environment-friendly type textile raw material；Internal layer 5 uses zein fiber inner layer, and zein fiber is softly smooth, Intensity is big, and moisture absorption is ventilative, and sense of touch is good, good anti-ultraviolet property.

Further, it is provided with controllable soft mould set on the elastic ear band 2, big minor adjustment is free and relaxed.

Further, the display 11 is used to show extraneous PM2.5 concentration, the concentration of formaldehyde gas and by outer The concentration of PM2.5 concentration and formaldehyde gas after layer, middle layer can clearly be learnt by the numerical value on comparison display 11 Mask role in terms of filtering poisonous harmful substance, and it can be clear from extraneous pollutant concentration, it prompts People reduce outgoing.

Further, nanometer titanium dioxide composite material layer 8 is combined by graphene and titanium dioxide, can be more The shortcomings that titanium dioxide can only use ultraviolet light is mended, so that can be carried out photocatalysis under visible light, it can be by air or room Interior organic pollutant, reaction, which is oxidized, under the catalytic action of light generates water and carbon dioxide, with energy-saving and environmental protection Feature.

Further, the middle layer 4 is detachable, and velcro, the outside setting of internal layer are provided on the inside of the outer layer Have a velcro, two sides of middle layer are provided with velcro, the middle layer by velcro respectively with internal layer and outer layer It is combined together.Not only ectonexine easy to clean in this way, but also it is convenient for changing the activated carbon adsorption layer in middle layer.

The beneficial effects of the utility model are: successively activated carbon adsorption layer, nano-titanium dioxide are multiple for mask body middle layer Condensation material layer and HEPA filter layer, can effectively adsorb peculiar smell, to dust particles, less than 2.5 microns can be effective Organic pollutant is catalytically decomposed in filtering, nanometer titanium dioxide layer, not only reduces the harm to human body, and energy-saving ring It protects；It is arranged and the concentration of PM2.5 and the concentration of formaldehyde is detected by setting PM2.5 concentration sensor and formaldehyde gas sensor, leads to It crosses display to show, not only understands people and know extraneous concentration levels, but also be also known that and pass through mask body outer layer With the concentration levels after middle layer, the filtration of mask is judged with this；When the concentration or first for detecting extraneous PM2.5 When the concentration of aldehyde is more than the value of setting, alarm is sounded an alarm, and people is prompted to reduce trip number to the greatest extent；It is set on elastic ear band Controllable soft mould set is set, the tightness of easy adjustment mask ear portions is suitble to different people.
