Description

Technical Field

[0001] The utility model relates to the technical field of water drinking machines, in particular to a water drinking machine with a terminal water outlet sterilization function. Background Art

[0002] In daily life, water dispensers are more common drinking water devices, and water dispensers are devices that heat or cool bottled pure water (or mineral water) and make it convenient for people to drink. Bottled water is placed on top of the machine and used in conjunction with bottled water. Water dispensers are generally divided into three types: warm, ice-hot, and ice-warm. Among them, ice-hot machines are divided into semiconductor refrigeration water dispensers and compressor refrigeration water dispensers. However, since there is a gap between the bottled water and the water dispenser connection port, it is very easy to breed bacteria inside the bottled water if it is placed for a long time. Some existing water dispensers disinfect drinking water by setting an activated carbon filter, but the disinfection effect is limited. At the same time, some activated carbon filters are fixedly installed inside the water dispenser and cannot be replaced. For this reason, we propose a water dispenser with end-water sterilization function. Utility Model Content
