Embodiment 1

[0059] Embodiment 1: The detection process of physical sunscreen products is as follows, such as Figure 1-Figure 5 :

[0060] Using state 1, when the skin is not coated with sunscreen products, the ultraviolet rays emitted by the detection device are irradiated on the detected skin, and part of the ultraviolet rays will be reflected and scattered by the skin surface and received by the ultraviolet sensor in the device. The received ultraviolet intensity is converted into an analog voltage value for output, and the voltage value is 1030mV. The processor will use the voltage signal at this time as the reference standard for skin SPF when no sunscreen products are used.

[0061] The formula for calculating the physical SPF is as follows:

[0062] UVSPF=((Uout-Uo)*H0 / V0-SPF0)*H1=((1030-1000)*4096 / 3300-37)*3=0, the sun protection level is weak.

[0063] Note: UVSPF is the sun protection factor, SPF0 is the index correction value, Uout is the output voltage value (mV) of the ultr...

Embodiment 2

[0070] Embodiment 2: The detection process of chemical sunscreen products is as follows, as figure 1 , figure 2 , Image 6 , Figure 7 and Figure 8 Shown:

[0071] Using state 1, when the skin is not coated with sunscreen products, the ultraviolet rays emitted by the detection device are irradiated on the detected skin, and part of the ultraviolet rays will be reflected and scattered by the skin surface and received by the ultraviolet sensor in the device. The received ultraviolet intensity is converted into an analog voltage value for output, and the voltage value is 1030mV. The processor will use the voltage signal at this time as the reference standard for skin SPF when no sunscreen products are used.

[0072] The chemical SPF calculation formula is as follows:

[0073] UVSPF=(SPF0-(Uout-Uo)*H0 / V0)*H1=(37-(1030-1000)*4096 / 3300)*3=0, the sun protection level is weak.

[0074] Note: UVSPF is the sun protection factor, SPF0 is the index correction value, Uout is the ou...

Abstract

The invention discloses a skin sun protection factor intelligent detection device and a usage method thereof. The detection device comprises a shell, wherein a display screen and a detection window are arranged on the surface of the shell, and an ultraviolet light generation source, an ultraviolet sensor and a processor are arranged inside the shell. The usage method comprises the following steps: (1) clinging the detection window of the detection device to the skin; (2) switching on the ultraviolet light generation source to emit UV component light source; (3) reflecting and scattering ultraviolet rays at the UV wave band, and reaching to the ultraviolet sensor; (4) feeding the signals back to the processor through the ultraviolet sensor; (5) obtaining the intensity of the reflected and scattered ultraviolet rays at the current stage by the processor; (6) judging the skin sun protection factor at the time through the processor, and displaying through the display screen; and (7) conducting corresponding selection operations by the user. By measuring the skin with and without sun-protective cosmetics, the sun protection effect of the sun-protective products can be judged, the skin of a consumer can be protected from being burnt after being solarized for a long time due to the use of products with bad sun protection effect.

Description

technical field [0001] The invention relates to the field of sun protection, in particular to an intelligent detection device for skin sun protection index and a method for using the same. Background technique [0002] Ultraviolet rays can cause damage to human skin. Excessive ultraviolet rays entering the body will increase melanin in the human body, causing skin aging and the formation of spots on the skin surface. In severe cases, it can lead to skin cancer. It is precisely because of this that sunscreen products have emerged at the historic moment. At present, sunscreen products are mainly divided into two types: physical sunscreen and chemical sunscreen. The principle of physical sunscreen is to reflect and scatter ultraviolet rays; the principle of chemical sunscreen is to absorb ultraviolet rays and convert them into a lower heat energy to release, so as to avoid the damage caused by ultraviolet rays to the skin. [0003] Although there are a wide variety of sunscree...
