The UVA region has the ultraviolet wavelength of 320-400nm, UVA is a terrible sunlight killer, and can penetrate through the surface layer of the skin and tissues below dermis by virtue of the relatively long wavelength and strong penetrating capability, so that the fine structures in the skin such as collagen, elastic fiber tissues and the like can be damaged, wrinkles and young lines are generated, and the skin is relaxed and aged. The ultraviolet wavelength of the UVB section is 280-320nm, and the transmission force reaches the surface layer of a human body, so erythema, red swelling, blister desquamation and the like can be caused. The wavelength of the UVC section is 200-280nm, most of the UVC section is blocked by the atmosphere, and the UVC section is far from harm to human bodies.

Detailed Description
In order to enable a user to conveniently detect the reduction degree of the sun-screening effect of the sun-screening cosmetics on the body in real time, provide important reference for the user to take measures such as additionally coating the sun-screening cosmetics and the like, and monitor the ultraviolet intensity and the like in the current environment in real time. The embodiment of the present invention achieves the approach of separately detecting the intensities of the UVA region and the UVB region in the ultraviolet light (all the following detections of ultraviolet light or ultraviolet light refer to the detection of the two regions). The design idea is that ultraviolet rays can absorb (or reflect) ultraviolet rays after irradiating a detection target, such as skin coated with sunscreen cosmetics, and the ultraviolet ray intensity after the absorption (or reflection) of the skin is detected by an ultraviolet ray detection module, so that the effect of the skin coated with the sunscreen cosmetics on the ultraviolet rays can be obtained. In addition, the UV light is compared to the directly measured UV light which has not been subjected to the action of a sunscreen cosmetic. The real-time protection effect of the sunscreen cosmetic can be obtained after data processing. In addition, according to actual requirements, the embodiment also additionally designs functions of detecting the environment ultraviolet intensity in real time and timing.
Structurally, the embodiment mainly comprises a sheet structure body, a light incident port, a detection port, a bidirectional reflection device (such as a prism with two reflection surfaces), and the like. The internal circuit mainly comprises a rechargeable battery, a power supply module, an ultraviolet detection module, a display module and a circuit thereof, a data processing module, a timing module, a main control module and the like. The following detailed description of the embodiments will be made in terms of four aspects, which are the detection principle and process, the different modes of detection, the timing function and the operation of the device, in conjunction with the accompanying drawings.
Firstly, detection flow and process:
the following describes specific detection principles and processes in steps, with reference to the "detection principle diagram" in fig. 1 and the "detection flow diagram" in fig. 2.
(101) Ambient light is injected
Ambient light L jets into from the light entrance, and the light entrance can place quartz lens, the inside optical element of protection device according to user's service environment. The quartz lens will block the ultraviolet rays by about 10%, affecting the precision to a certain extent.
(102) Splitting of light
A reflecting device is arranged below the light incidence port and reflects light to two directions, namely a direction A light beam and a direction B light beam.
(103) Treatment of direction A light beams
The light beam in the direction A is reflected by the reflecting device to form reflected light A1, the reflected light A1 irradiates the detection target E through the detection port, and then is reflected again by the detection target to form reflected light A2, the ultraviolet detection module C2 is placed in the reflecting direction of the reflected light A2, and the ultraviolet detection module C2 detects the intensity of ultraviolet light in the light beam at the moment. Specifically, UVA and UVB regions in the ultraviolet light are detected separately.
(104) Treatment of direction B beam
The direction B light beam is reflected by the reflecting device to form reflected light B1, and the reflected light B1 directly detects the intensity of the ultraviolet light by the ultraviolet detection module C1 in the direction of the reflected light B1. Specifically, UVA and UVB regions in the ultraviolet light are detected separately.
(105) Data processing
Through the above steps, the final uv light intensities of the direction a light beam and the direction B light beam are detected separately. After the final ultraviolet light in the two directions is subjected to data processing at different intensities, a current value representing the sun protection effect is output to a display screen, and the change of the sun protection effect of the detection target at different time periods can be embodied by observing the change of the value of the detected target at different time periods.
(106) Two effects of detected target on ultraviolet light on direction A light beam
Since sunscreen cosmetics generally have a chemical sunscreen type that absorbs UVA and UVB and a physical sunscreen type that reflects UVA and UVB. For the two different cases, the detection is in principle consistent, but the data processing is different. For the types of absorbing UVA and UVB, the final ultraviolet light intensity of the direction A light beam is positively correlated with the sunscreen effect of the detection target; whereas for the types of reflected UVA and UVB, the resulting uv intensity of the direction a beam is inversely related to the sunscreen effect of the target under test. For the two types of switching, the device is provided with a mode switching switch.
(107) Display module
The display module displays the sun protection effect values under different modes and the data such as the intensity of UVA and UVB sections in the environment ultraviolet rays through a display screen D.
II, detection mode:
the different modes of detection are described in steps below, with reference to the "detection mode diagram" of fig. 3.
(201) Main switch
And opening a main switch, and enabling the equipment to enter a working state, wherein the main switch is a switch button.
(202) Detecting ambient ultraviolet intensity
When the main switch is turned on, the device starts to detect the intensity of the environmental ultraviolet rays in real time and display related data on a display screen.
(203) Mode switch
The device has a mode switch. The mode switch is used for switching among three modes of non-opening, absorption UVA and UVB detection and reflection UVA and UVB detection. It is also a type of toggle button.
(204) Detection wait
After the mode switch starts to detect once, the equipment can delay and wait for a certain time to start to detect. The reason for this waiting is to let the user place the device on the detection target.
While the display screen will display the countdown. Detection begins when the countdown ends.
Thirdly, timing flow:
in some cases, where a user has a need to record the time of exposure to the sun, such as sunbathing, embodiments may record the time of exposure to the sun and the amount of uv exposure during that time period via a timing module. The steps are described below with reference to the "timing flow diagram" of FIG. 4.
(301) Main switch
And opening the main switch, and enabling the equipment to enter a working state.
(302) Timing switch
The opening of the time switch, which is a start button, has three functions of starting timing, resetting timing and stopping timing.
(303) Start timing
After the timing module starts timing, the recording of the current time and the detection and recording of the current environment ultraviolet intensity are simultaneously executed.
When the starting timing is started within a certain time of the ultraviolet intensity of the detection target, the recorded ultraviolet intensity is not the environmental ultraviolet intensity, but is replaced by the ultraviolet intensity of the detection target, and the real-time sun-proof effect of the detection target is obtained.
(304) Reset timer
Step 303 is performed immediately upon resetting the timer.
(305) Stop timing
After the timing is stopped, and the interval time between the start of the timing is displayed. At the same time, the ultraviolet irradiation during this period is displayed. The calculation of the ultraviolet irradiation amount at this time is calculated from the detected ambient ultraviolet intensity and the ultraviolet intensity of the detection target in the period from the start of the timing to the end of the timing.
While the display device will display the countdown. Detection begins when the countdown ends.
Fourthly, the operation mode of the equipment is as follows:
the operation of the device is also simple and will be described below.
(401) Detecting ambient ultraviolet intensity
Open master switch, equipment entering operating condition just can real-time detection environment ultraviolet intensity this moment, and the user only need will detect the light direction that the mouth orientation will detect, and the testing result can show in real time on the display screen.
(402) Detecting the absorption or reflection effect of ultraviolet rays of a detection target
After the equipment enters a working state, a corresponding mode is set, then the detection opening surface of the equipment is attached to a detection target, such as skin coated with sunscreen cosmetics, and the equipment is taken down after a certain time, and a detection result on a screen is checked.
(403) Timing device
After the equipment enters the working state, the timing button is used for starting, stopping or resetting the timing. The time counting is started and stopped, the ultraviolet irradiation amount in the period is processed and calculated according to the current state (1) or (2), and the result is displayed when the time counting is stopped.
In addition, the main structure of the device adopts a sheet design, and the device is small and exquisite in structure and convenient to carry. The internal light block and absorption design prevents the detection precision from being affected by the unwanted reflection of the internal light of the device in the structure.
The foregoing describes the general principles and features of the present invention and, together with the general principles of the invention, further modifications and improvements thereto, may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
