3. The intelligent direct drinking water supply and sale system as claimed in claim 1, wherein the water quality monitoring module further comprises a third water quality sensor connected to the water outlet of the multi-media filter, and/or the water outlet of the activated carbon filter, and/or the water outlet of the water softener.
4. An intelligent direct drinking water supply and sale system as claimed in claim 1, wherein a second water pump is connected to a water outlet of the purified water tank, and an ultraviolet sterilizer is connected in parallel to a pipeline between the second water pump and the purified water tank.
5. A water supply method of the intelligent direct drinking water supply and sale system as claimed in any one of claims 1-4, characterized by comprising a water quality adjusting and supply mode;
the water quality adjusting and supplying mode comprises the following steps: when the water quality detected by the second water quality sensor does not reach the standard, the water output by the main water outlet pipe in the non-negative-pressure water supply module is filtered by the pre-filtering component, pressurized by the first water pump and then conveyed to the main water outlet pipe through the first bypass pipe.
6. The water supply method according to claim 5, wherein the water quality adjusting water supply mode is specifically:
when the water impurities detected by the second water quality sensor exceed the standard, the water output by the main water outlet pipe is filtered by the multi-medium filter;
and/or when the water detected by the second water quality sensor has peculiar smell and different colors, the water output by the main water outlet pipe is filtered by the activated carbon filter;
and/or when the hardness content of the water detected by the second water quality sensor exceeds the standard, the water output by the main water outlet pipe is filtered by the water softener.
7. The water supply method according to claim 5, further comprising an energy saving water supply mode that: when the total water consumption of the user side is lower than a set value, the main water supply pump stops running, water introduced by the main water inlet pipe is conveyed to the first water pump through the second bypass pipe, and then is pressurized by the first water pump and conveyed to the main water outlet pipe through the first bypass pipe.
