[0021] The interior of the water purification tank 1 is hollow, and its main function is to store water inside, so that the water source can be effectively stationary to achieve the effect of making the drinking water clean.

[0022] Among them, a slide groove 18 is opened inside the clean water tank 1, and a slider 19 is slidably connected inside the slide groove 18. A filter plate 20 is fixedly installed on the surface of the slider 19, and a filter hole 21 is opened on the surface of the filter plate 20. A sealing cover 22 is fixedly installed on the top of the clean water tank 1.

[0023] The main function of the filter plate 20 is to filter the water source after the water source is injected into the clean water tank 1, so that the water supply inside the clean water tank 1 is cleaner.

[0024] A drain pipe 16 is fixedly installed at the bottom of the clean water tank 1 , and a drain solenoid valve 17 is rotatably connected inside the drain pipe 16 .

[0025] The main function of the drain solenoid valve 17 is to drain the water stored in the clean water tank 1 for a long time by controlling the switch drain pipe 16, so as to keep the water in the clean water tank 1 fresh at all times.

[0031] The main function of the return water flow meter 8 is to measure the return water, and then feed it back to the PLC 10 through the data line 9 for recording, so as to combine the water supply recorded by the water outlet flow meter 3 to calculate the total amount of water used.

[0032] The working principle and use process of this utility model:

[0033] First, there is a liquid level meter 12 in the clean water tank 1, and the liquid level of the clean water tank 1 is collected in real time through PLC10. The water supply pipe 2 5 is equipped with an outlet flow meter 3 and a return flow meter 8. The water supply pump 4 is responsible for delivering direct drinking water to the user end and returning the unused direct drinking water to the clean water tank 1. At 0:00 a.m. every day, the current values ​​of the outlet flow meter 3 and the return flow meter 8 are recorded. At 0:00 a.m. the next day, the PLC10 control system reads the current values ​​of the outlet flow meter 3 and the return flow meter 8, and calculates the actual incremental values ​​of the outlet flow meter 3 and the return flow meter 8 on that day, and then the actual water consumption on that day is obtained by subtracting the return flow meter 8 value from the outlet flow meter 3 on that day. According to the public V=Sh, the actual consumption height of direct drinking water can be calculated. Then the system compares the high and low liquid level setting values. The difference between the high and low liquid level settings is preferably 1.2 times the actual consumption height. Then the high liquid level value can be directly adjusted based on the low liquid level height. And the touch screen 15 sets a high liquid level limit. If the adjusted height exceeds the high liquid level limit, no adjustment is performed. If it is lower than the high liquid level limit, the high liquid level is automatically accumulated to 1.2 times the actual consumption height based on the low liquid level.

[0034] Secondly, the touch screen 15 sets the safe water use threshold and the safe water use cycle. If it is calculated that the daily water consumption during the safe water use cycle is less than the safe water use threshold, it means that the water in the clean water tank 1 has not been drunk or updated for a long time. In this case, the drain solenoid valve 17 is opened to update the drinking water in the clean water tank to ensure the freshness of the water quality.

[0035] Finally, the direct drinking water system with intelligent adjustment of the liquid level in the water purification tank 1 can ensure the safety of water use for users, with intelligent control, high stability and strong operability.
