Embodiment 1
[0035] On the one hand, this embodiment discloses a sunscreen performance testing device, see figure 1 , which includes a sunscreen smudge detection camera, a UV detector, and a sunscreen bottle, where:
[0036] The sunscreen smear detection camera is detachably installed on the smart mobile device, the sunscreen smear detection camera is connected with the CPU signal of the smart mobile device, and the sunscreen smear detection camera is used to detect the sunscreen of the object to be tested Smudge traces, and display the traces of sunscreen smear on the subject in real time on the display screen of the smart mobile device in gray scale real-time video images;
[0037] The ultraviolet detector is detachably installed on the sunscreen smear trace detection camera, and the ultraviolet detector is used to detect the ultraviolet intensity around the object to be tested, and the ultraviolet detector is equipped with an irradiation direction and a screen of an intelligent mobile d...
Embodiment 2
[0044] On the basis of embodiment 1, the sunscreen bottle is a roll-on bottle or a spray bottle. Roller bottles and spray bottles have mature technology. Using them can make the application and spraying of sunscreen even, and avoid the loss or insufficient local sunscreen function caused by partial application of sunscreen or insufficient spraying, so as to ensure the sunscreen performance.
[0045] A detachable installation method of the sunscreen smear detection camera and the ultraviolet detector is as follows: the sunscreen smear detection camera is connected to the smart mobile device, and the ultraviolet detector is connected to the sunscreen smear detection camera. Each component can be detachably installed on smart mobile devices such as mobile phones, tablet computers, and laptops, and the screen, CPU, power supply, etc. of smart mobile devices are used in the working process, which is convenient to carry and use while saving manufacturing costs and improving product q...
Embodiment 3
[0055] On the basis of Example 2, set the SPF and PA values of the currently used sunscreen, calculate the expiration time of the sunscreen, and automatically remind 10 minutes before the sunscreen expires.
[0056] The expiration time of the above sunscreen is calculated by the following method: Set the time after applying sunscreen and passing the sunscreen smear detection camera to pass the test (black imaging of the entire area) as T 0 , the interval time T 1 (Refer to the SPF value and PA value for determination) Use the sunscreen smear trace detection camera again for detection. When the detection result is qualified, the interval time T 2 Use the sunscreen smudge detection camera again to detect,,,, until the interval time T n If the first test result is unqualified, then T n -T 0 is the expiration time of the sunscreen, and input the expiration time of the sunscreen into the APP through the screen of the smart mobile device, and measure the expiration time of the ...
