The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Referring to fig. 1, the sterilization system is disposed in the waterway between the pure water end and the drinking water end, and performs sterilization treatment on the waterway of the pure water portion, thereby avoiding bacteria from affecting the drinking safety.

The sterilization system comprises 4 electromagnetic valves, namely a first electromagnetic valve 01, a second electromagnetic valve 02, a third electromagnetic valve 03, a fourth electromagnetic valve 04, two parallel water paths 10 and a water outlet 20, wherein a water path I at a pure water end is divided into the two parallel water paths 10, the first water path 11 comprises the electromagnetic valve 01, the second water path 12 comprises a mineral filter element 13 and an active oxygen generator 14, and the water flows to a drinking water end or the water outlet 20 after passing through the parallel water paths; a first solenoid valve 01 and a second solenoid valve 02 are respectively arranged at the branches of the first waterway 11 and the second waterway 12 to separately control the passages of the first waterway 11 and the second waterway 12; a third electromagnetic valve 03 and a fourth electromagnetic valve 04 are respectively arranged at the branch of the drinking water end and the water outlet 20. The third and fourth solenoid valves 03 and 04 control the flow of water to the drinking end and the discharge of water through the water discharge port 20, respectively.

Further, a UV light sterilizing part 30 is provided at a position before the drinking end and the water outlet 20 are branched after the water path 10 is connected in parallel. The UV light sterilization part is a cold cathode UV mercury lamp which is always bright and can provide double sterilization guarantee.

The mineral filter element is a mineral filter element capable of increasing the content of soluble solids (TDS) in pure water. TDS is the Total Dissolved Solids (TDS), also known as Total dissolved solids, measured in milligrams per liter (mg/L), and the TDS value indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. Higher TDS values indicate more solutes in the water.

Total dissolved solids refers to the total amount of total solutes in the water, including both inorganic and organic content. Generally, the salt content of the solution is known approximately by the conductivity value, and generally, the higher the conductivity, the higher the salt content, and the higher the TDS. Among inorganic substances, there may be inorganic substances in molecular form in addition to components dissolved in ionic form.

The mineral filter element is applied in the system to improve the TDS value of the pure water, and the active oxygen generator can not electrolyze the pure water with low TDS value.

The solenoid valve is a high pressure waterway solenoid valve.
