For example, when the water in tank body 1 is at second liquid level, at this time, the water in tank body 1 is more, and the controller controls germicidal lamp unit 2 to start sterilization, and the starting time can be set relatively long, when the water in tank body 1 is at first liquid level, at this time, the water in tank body 1 is less, and the starting time of the controller control germicidal lamp unit 2 can be relatively short or not selected.

[0060] As Figure 4As shown in the figure, the germicidal lamp unit 2 comprises a driving mechanism (not shown in the figure), a rotating member 21, a germicidal lamp 22 and a transparent cover 23. The rotating member 21 is vertically installed in the middle of the box body 1. The cover 23 is arranged outside the rotating member 21. The germicidal lamp 22 is installed inside the cover 23. The driving mechanism is used to drive the rotating member 21 to rotate. The controller is electrically connected to the germicidal lamp 22. The driving mechanism drives the rotating member 21 to rotate, and the rotating member 21 drives the germicidal lamp 22 to rotate, so that the germicidal lamp 22 can sterilize the water around it, increase the irradiation range, and thus improve the sterilization effect.

[0061] As shown in the figure, Figure 4 In this embodiment, the number of germicidal lamps 22 is two. The two germicidal lamps 22 are arranged on both sides of the rotating member 21 and are located at different height positions, so as to improve the sterilization effect.
