Description
Technical field
This utility model relates to a kind of test set that can measure skin moisture content, is widely used in daily skin care and beauty treatment.
Background technology
Skin moisture content determines by inside and outside two kinds of factors, and keratodermatitis keeps the moisture content capacity variation larger, and water content can from 10% to 60% changes, the composition of aqueous mixtures in topmost or the respiratory that skin is perspired and skin.External factor comprises ambient temperature, humidity, medicine and cosmetics etc., can determine and change the water content in skin.Skin moisture content can affect
The water on surface and the formation of oils and fats hybrid films.And this layer protecting film is very important to the aging that prevents skin.Therefore the test skin moisture content of quantification and relatively necessarily the variable quantity after the nursing stage be of great use.The skin quality situation of Measurement and analysis skin, as soft in moisture content, oil and skin and coarse,, in the situation that guarantee that skin is without any damage, can the instructor carry out the meticulous nursing of skin.
The utility model content
The technical problem that this utility model solves: traditional direct moisture measurement method cycle is long, is difficult to meet the requirement to speed and serialization.Have on traditional moisture content detection method principle: electric-resistivity method, capacitance method, infrared method, nuclear magnetic resonance, NMR, microwave method etc.The characteristics that electric-resistivity method is quick because of it, accurate, cost is low are the most frequently used moisture measurement methods always, but because there are the defects such as signal intensity is little, sampling requirement is high, anti-interference is poor in resistive method, many new innovative approach based on the resistance measurement principle have appearred in recent years, as two range dc resistance methods, the pulse resistance method, Research of Complex Impedance Separation Method, AC impedence method etc.This utility model is on above-mentioned Research foundation, and innovation ground proposes the data processing method based on bio-impedance Resistance Analysis method and measuring-signal, provides that a kind of cost is lower, convenient test, can measure rapidly the skin moisture measuring device.
the technical solution adopted in the utility model: skin analyzer, has skin inductive probe (1), micro-processor interface circuit (2), electric power management circuit (3), display circuit (4) and key circuit (5), it is characterized in that: an input of the output termination micro-processor interface circuit (2) of described skin inductive probe (1), another input of the output termination micro-processor interface circuit (2) of electric power management circuit (3), the input of an output termination display circuit (4) of micro-processor interface circuit (2), the input of another output termination key circuit (5) of micro-processor interface circuit (2).The model of described micro-processor interface circuit IC is SN8P2947.This LCDs output circuit has liquid crystal display 4 * 11 dot matrix to form.
We put into circuit with human body skin, and as a resistance, in certain scope, skin moisture is high, and the material of dissolving increases, and ionization degree increases, and electric current is larger, otherwise electric current is less.But also non-complete line relationship both.When moisture content one timing, temperature is high, and ionization degree increases, and resistance reduces, and measured value is higher; Otherwise, low.The novel micro-processor interface circuit of the novel employing of this use is revised it, has reduced the impact of extraneous factor, has improved the accuracy of measuring.It comprises measures main body, LCDs, measures the shell of controlling button, battery inductive probe and the main body of packing into.The inductive probe of measuring body front end directly and contact skin, shows skin by the micro-processor interface circuit computational analysis by display screen.
This utility model advantage compared with prior art:
1, measure the percent by volume of the comprehensive nutrient moisture content rate of skin, numeral shows, and is clear and intuitive.
2, adopt real bio-impedance technology, by micro-processor interface circuit, measure and revise, improved accuracy rate.
3, simple to operate, automatic shutdown.
This utility model has well solved the defects such as the resistive method signal intensity is little, sampling requirement is high, anti-interference is poor, and micro-processor interface circuit is measured and revised, and has improved accuracy rate.
