This utility model discloses a thermally insulated and vibration-damping enclosure for an optical feedback cavity enhanced Raman spectroscopy detection instrument, belonging to the field of thermally insulated enclosure technology. It includes an insulation layer inside the main body of the outer shell, a reflective fiber optic coupler inserted into the right side of the main body through an optical path through-hole, and a temperature control component connected to the main body. This utility model uses a simple-structured main body made of high-strength aluminum alloy, with anodized and painted surfaces to improve corrosion resistance. The insulation layer ensures the system maintains internal temperature stability even when external ambient temperatures fluctuate. The temperature control component effectively diffuses the thermal gradient generated by the TEC (Electrical Temperature Coefficient) throughout the entire internal space of the enclosure through forced convection heat transfer, thereby minimizing local temperature differences and achieving a consistent internal temperature field. This maintains stable internal temperature, improves measurement accuracy, and enhances the long-term stability of the laser frequency and the robustness of Raman spectroscopy measurements.

Simultaneously, it ensures system stability through grouped sequential control and safety monitoring, and utilizes a cloud platform to aggregate multi-site data for global optimization scheduling and model iteration. This invention effectively reduces defrosting energy consumption, maintains stable storage / cabinet temperatures, and improves the operating efficiency and intelligent management level of the refrigeration system.

This invention discloses a light-emitting structure for a hair removal device and the device itself. The light-emitting structure includes a light source assembly, a cooling assembly, and a heat-insulating sealing structure disposed between the light source assembly and the cooling assembly. The heat-insulating sealing structure includes a heat-insulating film and a corrugated sealing ring. The first end of the corrugated sealing ring is nested on the cooling assembly. The second end of the corrugated sealing ring is used to tightly adhere the heat-insulating film to the light-emitting surface of the light source assembly, preventing impurities from falling onto the light-emitting surface and preventing heat transfer between the light source assembly and the cooling assembly. This reduces the entry of dirt and debris, reduces heat transfer between the light source assembly and the cooling assembly, reduces condensation, improves the cooling effect of the cooling assembly during light emission, and extends the device's lifespan.
