and a second one-way valve for preventing water in the pure water tank from flowing backwards is further arranged on the pipeline between the fourth water inlet valve and the pure water tank, and when the water outlet NTC detector detects that the water temperature in the pipeline reaches a user set value, the fourth water inlet valve stops draining water to the pure water tank and is directly communicated with the water outlet nozzle to supply water.
5. A cool boiled water direct drinking water supply processing system according to claim 1, wherein a second water inlet valve is further provided on the pipeline between the pure water tank and the heat exchange module, the second water inlet valve being communicated with the water inlet end of the water pump and being used for avoiding the heat exchange module to directly lead out the normal temperature pure water, the second water inlet valve adopts a water control structure with one inlet and two outlets, the water inlet of the second water inlet valve is communicated with the water outlet of the pure water tank through the pipeline, and the two water outlets of the second water inlet valve are respectively communicated with the heat exchange module and the water pump through the pipeline.
6. A cool boiled water direct drinking water supply processing system as claimed in claim 1, wherein the water inlet of the pure water tank is further provided with a post carbon rod filter element for adjusting the PH of the pure water filtered by the PP and carbon rod composite filter element and the RO membrane filter element to improve the taste of the pure water.
7. A cold boiled water direct drinking water supply processing system as claimed in claim 1 or 6, wherein the pure water tank is further provided therein with a pure water high level detector and a pure water low level detector for detecting the level of pure water in the tank, respectively.
8. The system for directly drinking and supplying cold boiled water as claimed in claim 1, wherein a raw water low level detector for detecting that the tap water is at a low level is arranged on the bottom side wall of the tap water storage chamber in the raw water tank, and a water changing level detector for controlling water changing in the cavity is arranged on the bottom surface of the tap water storage chamber.
9. A cool boiled water direct drinking water supply processing system as claimed in claim 1, wherein the heat exchange module is a plate heat exchanger or a coil heat exchanger composed of concentric inner and outer pipes, the inner pipe of the coil heat exchanger is a hot water pipe communicated with the boiled water return pipeline, and the outer pipe is a cooling water pipe communicated with normal temperature pure water supplied by the pure water tank.
10. The cool boiled water direct drinking water supply processing system as claimed in claim 1, wherein a raw water TDS probe for measuring the degree of water quality cleanness is further arranged on a supply pipe between the raw water tank and the self-priming pump; and a pure water TDS probe for measuring the cleanness degree of water is further arranged on the pure water supply pipeline between the RO membrane filter element and the pure water tank.
11. A cool boiled water direct drinking water supply processing system as claimed in claim 1, wherein the pure water tank is further provided with a UV-LED bacteriostatic lamp for inhibiting bacteria generation of pure water or a post carbon rod filter element in the tank.
