Specific embodiment
The content of present invention is illustrated below in conjunction with embodiment.
The present invention provides a kind of face protection articles, including ontology, for covering at least facial mouth and nose when use.This
Inventing the face protection articles includes but is not limited to mask, mask, headgear, the helmet, scarf etc..Corresponding to different types of face
Portion's protective articles, ontology can be respectively mask body, mask body, headgear ontology, helmet main body, respectively with conventional mouth
Cover, mask, headgear, helmet shape are similar, for example, mask body includes the hangers for covering the cover of mouth and nose and connecting with cover
Band, mask body include the fixing belt that covering face only exposes the cover of eyes and connect with cover, and headgear ontology includes covering
The cover of eyes is only exposed on head, and helmet main body includes the cover that eyes are only exposed on covering head made of hard material.This hair
Bright main innovation point is to add functional sheet in face protection articles, the functional sheet have air filtering function and be powered from
Heating function, after functional sheet is connect with ontology, guarantee human body incoming call loading of air pollutant it is low, and by air be heated to compared with
Suitable temperature builds a comfortable facial air environment, is particularly suitable for using under cold conditions, is also suitble to transport in winter
Moving scholar reduces injury or sense of discomfort of the cold air to its respiratory system.
The implementation method of air filtration according to the present invention is the micro gap resistance by stereoscopic grid or fine and close plane
Every the micropollutants in air, this cubic network can such as melt spraying non-woven fabrics or nanofiber.Electrostatic can also be passed through
Suction-operated captures micropollutants, such as the conductive porous three-dimensional network of porous carbon.
Preferably, the inside of ontology is arranged in (i.e. close to face or people in face protection articles of the invention, functional sheet fitting
Body side), outside (i.e. far from face or human body side) or be embedded in the body interior.It is used using face protection of the invention
When product, air enters on the inside of ontology from outer body mainly to be realized by human body air-breathing, naturally it is also possible to be taken out by air pump
Gas.Air passes through the filter layer of functional sheet and realizes air filtering function, and cold air passes through the functional sheet of energization spontaneous heating
When can be heated to required temperature, since filter layer and heating layer are all integrated in functional sheet, a movement can be simultaneously
Realize above-mentioned two function.
Preferably, in another preferred embodiment of the present invention, the temperature for detection function piece temperature is also set up in ontology
Sensor is spent, the temperature of control function piece is located in preset range.For example, functional sheet includes heating layer, temperature is excessively high
Face can be scalded, temperature is too low to be not achieved warming effect.By the actual temperature of temperature sensor real-time detection function piece, realize
Feedback control avoids temperature too low or too high.Preferably, it by analyzing temperature sensor signal, is only used in wearer
When outside air be lower than preset value when, heating system is just started to work, and so as to improve usage experience and saves electricity.
Preferably, in another preferred embodiment of the present invention, functional sheet includes heating layer, is heated by resistance-type, hair
Specific resistance v. temperature variation characteristic possessed by hot material, that is, temperature-coefficient of electrical resistance feature, so that heating layer can either
It can be used as temperature sensor again as resistance heater.The power electric connection of heating layer and setting in the body, the electricity of heating layer
