Description

Technical Field

[0001] This utility model relates to the technical field of sunscreen testing equipment, specifically to a device for detecting the ultraviolet isolation time of sunscreen. Background Technology

[0002] With increasing awareness of skin protection, sunscreen has become an important part of daily skincare, and its protective effect, especially the duration of ultraviolet (UV) protection, has become a crucial factor for consumers when choosing products. To scientifically and accurately evaluate the protective effects of different brands and formulas of sunscreen in practical applications, a sunscreen UV protection time testing device was specifically designed. Common sunscreen UV protection time testing devices consist of a pad, a xenon arc lamp sunlight simulator, and an erythema recorder. The following drawbacks were found during their use:

[0003] 1. Currently, most sunscreen UV protection time testing devices can only test a single brand of sunscreen one by one, which limits efficiency, especially when comparing the protective effects of multiple products. Furthermore, for tests using human skin as the testing subject, existing devices often lack an effective rapid arm positioning mechanism, requiring manual adjustment before each test. This is not only time-consuming and labor-intensive but may also affect the consistency and accuracy of test results due to inaccurate positioning.

[0004] 2. During the experiment, due to the significant differences in height among the participants, a fixed device height may cause discomfort or difficulty in maintaining the correct posture for some. This is particularly detrimental to long-term testing, as poor posture may affect the participant's comfort and stability, thereby interfering with the test results.

[0005] Therefore, in view of this, the existing structure was studied and improved, and a sunscreen ultraviolet isolation time detection device was proposed. Utility Model Content
