Abstract
Description
Technical Field
[0001] This utility model relates to the field of sunscreen detection technology, specifically to a sunscreen ultraviolet isolation detection device. Background Technology
[0002] The UV blocking ability of sunscreen is a key factor in evaluating its quality. In the research and development, quality testing, and market application of cosmetics, the ability to quickly and accurately test the UV blocking performance of sunscreen products is of significant practical importance.
[0003] Currently, the commonly used detection method involves manually applying a sunscreen sample onto a glass slide or skin-like carrier, then irradiating it with ultraviolet light and observing the color change of the test paper or photosensitive material underneath to determine the degree of ultraviolet light transmission. This method has several drawbacks: firstly, sample replacement requires manual operation, and the coated carrier must be cleaned or replaced after each test, making the process cumbersome and inefficient; secondly, this method is not suitable for continuous testing and rapid comparison of multiple samples, and cannot meet the high-frequency testing needs of actual product screening or quality control.
[0004] Therefore, there is an urgent need for an ultraviolet isolation detection device that is simple in structure, convenient for sample replacement, and can meet the needs of continuous detection, so as to improve detection efficiency and the repeatability and comparability of detection results. Utility Model Content
[0005] In view of the shortcomings of the existing technology, this utility model provides a sunscreen ultraviolet isolation detection device, which aims to alleviate the above problems to at least a certain extent.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A sunscreen ultraviolet radiation isolation detection device, comprising:
[0008] Test box;
[0009] A detection cover plate located on the top of the detection box body is connected to the detection box body via a hinge;
[0010] A connection opening is provided at the top of the detection box;
[0011] A thin film is disposed inside the detection box. One end of the thin film extends through one of the connection openings to the top of the detection box and returns to the detection box through another connection buckle. One end of the thin film is laid flat on the surface of the detection box.
[0012] An ultraviolet lamp is installed inside the detection cover plate;
[0013] A detection opening is provided on one side of the detection box for inserting test strips.
[0014] Preferably, the top of the detection box has a penetrating opening, and a glass plate is provided inside the penetrating opening.
[0015] Preferably, a connecting frame is provided on one side of the detection box, and a connecting opening is provided on the connecting frame to communicate with the detection opening, and a receiving plate is provided in the connecting opening.
[0016] Preferably, a limiting frame is connected to the receiving plate.
[0017] Preferably, two rollers are rotatably connected to the connecting frame, one end of the film is wound on one roller and the other end is wound on the other roller, and a motor is provided inside the connecting frame, the drive shaft of the motor being connected to one of the rollers.
[0018] Preferably, one side of the connecting frame is connected to a snap-fit frame, which is interference-fitted with the detection box.
[0019] In summary, the present invention has the following main advantages:
[0020] Through the above setup, this device achieves a closed-loop arrangement of the sample carrier. After each test, the sample area can be quickly replaced by rolling up the film, avoiding the cumbersome process of frequent carrier disassembly and cleaning in traditional detection methods. This structural design significantly simplifies sample replacement operations, improves overall detection efficiency, reduces the risk of sample cross-contamination, and ensures the accuracy and consistency of each test.
[0021] Furthermore, the cyclic arrangement of the film allows for continuous testing of different samples, avoiding sample contamination issues caused by manually changing the carrier and improving the repeatability and stability of the testing process. Simultaneously, this design reduces coating errors and ensures that the samples on the film are always within the same light path, guaranteeing consistent ultraviolet transmittance testing conditions and effectively minimizing the interference of human factors on the test results.
[0022] During the testing process, the ultraviolet lamp is integrated with the testing cover, which can turn on ultraviolet irradiation when the cover is closed and turn off when the cover is opened and closed after the test, reducing the potential hazards of accidental exposure to ultraviolet light.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] refer to Figures 1-5 A sunscreen ultraviolet radiation isolation detection device, comprising:
[0034] Test box 100;
[0035] The detection cover plate 101 located on the top of the detection box 100 is connected to the detection box 100 via a hinge;
[0036] A connection opening 102 is provided at the top of the detection box 100;
[0037] A thin film 103 is placed inside the detection box 100. One end of the thin film 103 extends through one of the connection openings 102 to the top of the detection box 100, and then passes through another connection buckle back into the detection box 100. One end of the thin film 103 is laid flat on the surface of the detection box 100.
[0038] An ultraviolet lamp 104 is installed inside the detection cover plate 101;
[0039] A detection opening 105 is provided on one side of the detection box 100 for inserting test strips;
[0040] With the above setup, during use, one end of the film 103 extends from the side of the detection box 100 through the opening 102 to the top, and after being laid flat, returns to the detection box 100, achieving a closed-loop arrangement of the film 103 before and after detection. This structural design not only avoids the problem of frequent cleaning or replacement of sample carriers in traditional detection methods, but also enables rapid sample switching, effectively improving detection efficiency. Users only need to apply the sunscreen sample to be tested to the flat section of the film 103 and quickly switch between different samples by rolling the film 103, reducing the possibility of sample cross-contamination while ensuring the accuracy and consistency of each test.
[0041] During testing, the test strip is inserted into the test box 100 through the test opening 105, aligning it with the position of the sunscreen sample. After the test cover 101 is closed to the top of the test box 100, the ultraviolet lamp 104 located inside the test cover 101 is turned on, irradiating the sunscreen-coated film 103 segment with ultraviolet light. Since the ultraviolet light must first penetrate the sunscreen sample on the film 103 before irradiating the test strip below, the ultraviolet light is significantly absorbed and blocked when passing through the sunscreen layer, resulting in a significant reduction in its intensity. This allows the color change of the test strip to directly reflect the ultraviolet blocking performance of the sample. This process avoids the cumbersome traditional single-sample coating and disassembly process, while ensuring the consistency of ultraviolet irradiation conditions, reducing errors introduced by manual operation, and significantly improving the repeatability and efficiency of the test.
[0042] After the test is completed, the test cover 101 is opened, and the ultraviolet lamp 104 is turned off, stopping the irradiation of the sample and avoiding unnecessary energy consumption. This also prevents potential hazards from accidental exposure to ultraviolet light. At this time, the tested film 103 segment can be rolled into the test chamber 100 by rolling it up, while a new film 103 segment is pulled out to the test position, quickly updating the test area. This further improves sample replacement efficiency, reduces the risk of cross-contamination, and ensures consistent testing conditions for different samples, providing a reliable guarantee for continuous testing of multiple samples.
[0043] The aforementioned test strips can be UV-changing test strips, photosensitive grayscale test strips, or UV-sensitive films. UV-changing test strips typically change color rapidly upon contact with ultraviolet light, and the intensity of the color is directly related to the intensity of the ultraviolet light. Photosensitive grayscale test strips produce a significant grayscale change under ultraviolet irradiation, which can be used to precisely assess the transmittance of samples. UV-sensitive films undergo a photochemical reaction under ultraviolet irradiation, recording the cumulative energy of ultraviolet light, which can be used for subsequent quantitative analysis. Different types of test strips can be selected according to actual testing needs to meet the evaluation requirements of different sunscreen products for ultraviolet protection effectiveness. As a further embodiment of this invention, the top of the detection box 100 has a penetration opening 106, and a glass plate 107 is disposed within the penetration opening 106.
[0044] With the above configuration, the glass plate 107 is placed inside the penetration opening 106 at the top of the detection box 100, so that the ultraviolet light emitted by the ultraviolet lamp tube 104 can penetrate the glass plate 107 and irradiate the sunscreen sample on the film 103 while keeping the detection environment sealed.
[0045] As a further embodiment of this utility model, a connecting frame 200 is provided on one side of the detection box 100, and a connecting opening 201 communicating with the detection opening 105 is provided on the connecting frame 200, and a receiving plate 202 is provided inside the connecting opening 201.
[0046] With the above configuration, the receiving plate 202 can be used to receive the test strip, so that the test strip can be stably positioned below the film 103 after being inserted into the detection opening 105, thus avoiding the test strip from shifting or bending during the detection process.
[0047] As a further embodiment of this utility model, a limiting frame 203 is connected to the receiving plate 202;
[0048] With the above settings, the limiting frame 203 can effectively limit the test strip on the receiving plate 202, ensuring that the test strip remains stable during the testing process and will not be displaced due to external interference or equipment movement.
[0049] As a further embodiment of this utility model, two rollers 300 are rotatably connected to the connecting frame 200. One end of the film 103 is wound on one of the rollers 300 and the other end is wound on the other roller 300. A motor 301 is provided inside the connecting frame 200, and the drive shaft of the motor 301 is connected to one of the rollers 300.
[0050] With the above setup, one end of the film 103 is wound onto two rollers 300, and one of the rollers 300 is driven by a motor 301 to rotate, enabling the film 103 to move automatically and cyclically within the detection chamber 100. During the detection process, after each detection, the motor 301 drives the roller 300 to rotate, which can quickly wind the used film 103 segment back onto the roller 300 and simultaneously pull a new film 103 segment to the detection position, completing the rapid replacement of the sample area.
[0051] This structure not only significantly simplifies sample replacement operations, avoiding the cumbersome steps of manually pulling the film 103 in traditional detection devices, but also reduces the risk of sample cross-contamination, ensuring the accuracy of each test. Furthermore, the roller 300 system driven by the motor 301 provides a stable and controllable film 103 movement speed, further enhancing the automation level and detection efficiency of the equipment.
[0052] As a further embodiment of this utility model, a snap-fit frame 302 is connected to one side of the connecting frame 200, which is interference-fitted with the detection box 100.
[0053] With the above configuration, the snap-fit frame 302 and the detection box 100 are connected by an interference fit, allowing the connecting frame 200 to be easily disassembled and reassembled while maintaining a stable installation. When the membrane 103 needs to be replaced, simply remove the connecting frame 200 from the detection box 100 to easily remove the old membrane 103 from the roll 300 and install the new membrane 103. This reduces the tedious operation of disassembling screws or complex fixing structures and significantly improves the replacement efficiency of the membrane 103.
[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
