Technical Field

[0001] This utility model relates to the field of ultraviolet detection technology for sunscreens, specifically, to a cosmetic sunscreen SPF value measuring instrument. Background Technology

[0002] A cosmetic sunscreen SPF value meter is a device used to test the SPF value of sunscreens. SPF measures the sunscreen's ability to effectively protect against UVB radiation; a higher SPF indicates stronger protection. This instrument calculates the SPF value by simulating UV exposure and measuring the skin's reaction after applying sunscreen. The device typically includes a UV lamp source, sensors, and a data analysis system. It can automatically evaluate different types of sunscreen products. Accurate SPF testing helps consumers choose sunscreens that suit their needs and also provides important data for sunscreen product research and quality control. Such instruments have significant applications in scientific research, production, sales, and quality testing.

[0003] While existing sunscreen SPF value testers are highly accurate in testing the SPF value of sunscreen products, their traditional designs have certain limitations.

[0004] First, traditional instruments are bulky and usually require a dedicated testing environment and fixed device, which greatly reduces the portability of the equipment and makes it difficult to conduct rapid testing anytime and anywhere. For researchers, manufacturers and consumers who need to conduct sun protection tests in different occasions and multiple locations, the inconvenient instruments increase the complexity of operation and the limitations of use.

The drive motor 902 drives the synchronous pulley 801 through the transmission belt 802, thus affecting the movement of the entire ultraviolet detection device.

[0064] Working principle:

[0065] The protective component 1 has a movable slot 102 and provides necessary light protection for the ultraviolet identification test strip 10 through the light-shielding plate 103. The light-shielding slot 104 provides light isolation for the ultraviolet identification test strip 10 during the experiment, ensuring that the measurement process is not affected by external ambient light sources. Through this design, the protective component 1 not only effectively prevents ultraviolet rays from causing unnecessary damage to the test strip, but also makes the device more stable and operable. The guiding component 2, through the cooperation of multiple support bars 201 and guide rails 202, precisely guides the horizontal movement of the sample placement component 5, ensuring that the ultraviolet identification test strip 10 can be stably moved to different positions along a predetermined trajectory during the test. This design can improve the accurate placement of the sample and reduce the risk of damage during the measurement process.

This design improves testing accuracy and simplifies the operation process. The transmission component 6, via two lead screws 601, drives the slider 602 to move horizontally, thereby moving the placement frame 501 horizontally to the designated position. The combination of lead screws 601 and slider 602 enables high-precision linear motion. To ensure accurate positioning of the UV identification test strip 10 during testing, the slide rail 603 ensures smooth movement of the slider 602, avoiding any errors caused by friction or instability, thus guaranteeing testing accuracy. The UV detection component 7 controls multiple UV lamps 703 and flash lamps 704 via the PCB integrated circuit board 701 to emit UV light, which illuminates the UV identification test strip 10. A multi-angle wide-angle camera 705 captures changes on the surface of the UV identification test strip 10 in real time, and analyzes the changes in UV intensity through an image processing system. This component can monitor changes in the test strip in real time according to different UV irradiation intensities, providing accurate data for calculating the SPF value. The synchronization component 8 consists of two synchronization wheels 801.The two synchronous pulleys 801 are respectively fixed to one end of the two lead screws 601. The function of the synchronous pulleys 801 is to synchronize the movement between the two lead screws 601 through the transmission belt 802, ensuring that they always work synchronously during operation. The transmission belt 802 is sleeved on the outside of the synchronous pulleys 801, and its function is to drive the entire system to operate by rotating the synchronous pulleys 801. Since the synchronous pulleys 801 are connected to the lead screws 601, the transmission belt 802 realizes the synchronous rotation of the lead screws 601 through the rotation of the synchronous pulleys 801. The design of the transmission belt 802 can effectively transmit power and ensure The device's components operate precisely and synchronously, reducing mechanical friction and energy loss, and improving overall efficiency. The drive motor 902 connects to one of the synchronous pulleys 801 via its rotating end, driving the pulley 801 to rotate, which in turn drives the lead screw 601 and the entire transmission system.
