The conventional tap water in some areas contains sediment, heavy metal, pesticide residue or germs, a proper water treatment device is used to obtain better quality of water. Ultraviolet-ray lamp is usually applied to be one of the effective ways to sterilize the water, the ultraviolet ray can prevent the germs or micro-organisms from reproduction by means of reaction of the wavelength of the ultraviolet ray.
When the outlet 912 is not opened to let the water to come out, the water is still and keeps on being exposed to the ultraviolet-ray lamp 93, and this makes the still water have a high temperature so that when this portion of the water is released from the outlet 912, the high temperature may burn some users, and most of the users discard the water with high temperature. This wastes water significantly, and reduces the service lift of the ultraviolet-ray lamp 93.
