[0002] Cultural relic storage cabinets are used to store and classify cultural relics in the warehouses of cultural relics institutions. They are suitable for museums, art galleries, and other cultural relic collection institutions, where the preservation of cultural relics places strict environmental requirements. Chinese patent document CN217125717U discloses an airtight constant humidity cultural relic storage device, belonging to the technical field of constant humidity cultural relic storage devices. The device comprises a storage box with airtight doors rotatably connected to both sides of the front surface of the storage box. The utility model comprises a heater inside a constant-temperature water tank that heats water, a circulating water pump that pumps water into an insulated water pipe, and the insulated water pipe, which maintains the temperature of the cultural relics on the storage rack in a sealed environment. The atomizing humidifier sprays moisturizing water mist and activates a circulating fan. Driven by the wind of the circulating fan, the mist is evenly filled inside the storage box, maintaining a uniform constant humidity environment for the cultural relics on the storage rack. When the humidity inside is high and ventilation is required, the electric telescopic rod is activated to lift the sealing plate and open the sealing valve, allowing the ventilation pipe and the vent pipe to circulate. The ventilation fan is activated to quickly ventilate the cultural relics. Such a constant-humidity cultural relics protection device can ensure that the relative humidity of the storage cabinet is constant at a specific appropriate percentage by reducing the amount of air exchange. However, existing cultural relics such as iron and bronze artifacts require a low-humidity storage environment to prevent rust. After the storage cabinet is sealed, most existing equipment directly uses air drying to achieve a low-humidity environment. After the storage cabinet is sealed, the airflow direction of the sealed storage cabinet is single, and the airflow in the corners is difficult to discharge. This makes it inefficient to achieve a completely uniform low-humidity environment in the storage cabinet. Utility Model Content
