Description

Technical Field

[0001] The invention relates to the technical field of photoaging experimental equipment, in particular to an irradiation device used for skin failure light experiment. Background Art

[0002] In photoaging experiments, ultraviolet irradiation equipment is usually used to accurately simulate and accelerate the aging process of materials or organisms under natural light conditions and to ensure the controllability and repeatability of experimental conditions. In order to allow the experimental subjects to more effectively simulate the process of photofailure of human skin, mice with genes and skin structures that are highly similar to humans are usually used as experimental subjects.

[0003] The patent with application number CN202320449251.2 discloses an ultraviolet irradiation test device, a box body and an ultraviolet irradiation component. A test chamber with an opening on the top is provided inside the box body, a top cover is provided at the opening of the test chamber, a water tank is provided at the bottom of the test chamber, a heating device is provided in the water tank, a sample placement table is installed above the water tank, a sample is placed on the sample placement table, the ultraviolet irradiation component is arranged on the inner wall of the test chamber, and the ultraviolet irradiation component is located above the sample, which can effectively simulate the environmental conditions in the natural climate to conduct accelerated weather resistance tests on the test materials, and has a simple structure and is easy to assemble and disassemble.

[0004] In traditional skin failure photoaging experiments, in order to limit the movement of mice during the experiment, special fixing devices are usually needed to fix the mice. However, the use of fixing devices may cause the mice to feel anxious and nervous due to fixation, which in turn affects the function of their endocrine and immune systems, thereby having a certain impact on the experimental results. In addition, in traditional experiments, long-term non-feeding will cause the mice to starve and lose physical strength. In this case, the mice cannot maintain a normal physiological state, and effective skin failure photoaging experiments cannot be carried out. Therefore, it is necessary to conduct skin failure photoaging experiments on mice for a long time and multiple times, but this will extend the overall cycle of the experiment.

[0005] In view of this, we propose an irradiation device for skin failure photoexperiments. Summary of the invention

[0044] Furthermore, during the light experiment, the experimental mice walked in the circular track between the outer ring body 221 and the inner cylinder body 222, which drove the arc-shaped slide plate 241 to move. When the plate wall rack 242 collided with the docking gear 256, the docking gear 256 was driven to rotate, and the disk wall ring gear 252 and the rotating disk 251 were driven to rotate. After the disk body through hole 2510 of the rotating disk 251 moves to the bottom of the material guide groove 2250, a certain amount of feed will fall into the inside of the disk body through hole 2510, and when the disk body through hole 2510 moves to the top of the material guide groove 2250 along with the rotating disk 251, the feed will immediately fall from the material guide groove 2250 to the top surface of the arc-shaped connecting plate 224.

When the plate wall rack 242 collided with the docking gear 256, the docking gear 256 was driven to rotate, and the disk wall ring gear 252 and the rotating disk 251 were driven to rotate. After the disk body through hole 2510 of the rotating disk 251 moves to the bottom of the material guide groove 2250, a certain amount of feed will fall into the inside of the disk body through hole 2510, and when the disk body through hole 2510 moves to the top of the material guide groove 2250 along with the rotating disk 251, the feed will immediately fall from the material guide groove 2250 to the top surface of the arc-shaped connecting plate 224.
