A slider 402 is connected to one side of the top cover 102, and the slider 402 can be fixed to the top cover 102 by bolts, snap-fitting, or welding.

[0035] The top cover 102 and the column 101 are connected by a locking structure. The locking structure consists of a sliding groove 401, a slider 402, and a locking bolt 403. The slider 402 has a threaded hole that matches the locking bolt 403, and an opening that matches the sliding groove 401. The top cover 102 can move up and down along the sliding groove 401, and the distance the locking bolt 403 enters the threaded hole fixes the top cover 102 at a certain position in the vertical direction of the column, allowing for flexible adjustment of the distance between the top cover 102 and the base 103. A scale can also be installed on the column 101 to better adjust the height of the top cover 102 on the column 101.

[0036] An ultraviolet LED lamp 301 is mounted on the side of the top cover 102 facing the base 103. The irradiation distance between the ultraviolet LED lamp 301 and the base 103 can be adjusted by the aforementioned locking structure. The irradiation distance can be adjusted within the range of 20~60 cm, for example, 20 cm. To ensure the uniformity of ultraviolet irradiation, the ultraviolet LED lamps 301 are arranged in an array, and the number of ultraviolet LED lamps 301 can be selected according to the size of the irradiated area.

An ultraviolet sensor is mounted on the base 103 to detect the irradiance generated by the ultraviolet LED lamps 301. The brightness and number of ultraviolet LED lamps 301 can be adjusted based on the ultraviolet intensity signal detected by the sensor, thereby adjusting the ultraviolet intensity in a timely manner and improving the sterilization effect. The adjustment of the ultraviolet LED lamps 301 can be controlled manually or automatically.

Heat dissipation air inlets 104 are also provided on both sides of the top cover 102, and a zigzag or serpentine heat sink (not shown in the figure) is installed inside the top cover 102. The heat dissipation air inlets 104, the heat sink, and the fan 107 constitute the heat dissipation system of the ultraviolet irradiation device, which can dissipate excess heat inside the top cover 102 in a timely manner, ensuring that the equipment is always in a good operating condition.
