In this embodiment, the mouth feel water purifying unit 40 includes an activated carbon filter cartridge.
In this embodiment, during the use process of the water purification system, the water consumption can be determined by the pulse signal of the second pulse flowmeter 80, so as to control the water purification system to start or stop, realize pressureless operation, and prevent the water hammer effect. When water is started, the water flow starts to generate pulse signals, the water purification system performs water purification operation, and when water is closed, the water flow is static and abnormal pulse is prevented from being generated by the water backflow through the check valve 70, and the water purification system stops the water purification operation. The weak pressure between the check valve 70 and the water switch due to the water make-up ensures that the next pulse of water is initiated.
In this embodiment, during the use process of the water purification system, the water consumption can be determined according to the second pulse flowmeter 80, the input voltage of the booster pump 20 can be adjusted in real time, and the accurate water output control can be realized within a certain range.
When the input voltage of the booster pump 20 is 12V, the working flow rate is 1060ml/min, and when the input voltage of the booster pump 20 is 15V, the working flow rate is 1240ml/min; when the input voltage of the booster pump 20 is 16V, the working flow rate is 1420ml/min; when the input voltage of the booster pump 20 is 17V, the working flow rate is 1560ml/min; when the input voltage of the booster pump 20 is 18V, the working flow rate is 1680ml/min; when the input voltage of the booster pump 20 is 19V, the working flow rate is 1820ml/min; when the input voltage of the booster pump 20 is 20V, the working flow rate is 1940ml/min; when the input voltage of the booster pump 20 is 21V, the working flow rate is 2080ml/min; when the input voltage of the booster pump 20 is 22V, the working flow rate is 2200ml/min; when the input voltage of the booster pump 20 is 23V, the working flow rate is 2320ml/min; when the input voltage of the booster pump 20 is 24V, the working flow is 2460ml/min; when the input voltage of the booster pump 20 is 25V, the working flow rate is 2600ml/min; when the input voltage of the booster pump 20 is 26V, the working flow is 2720ml/min; when the input voltage of the booster pump 20 is 27V, the working flow is 2840ml/min; when the input voltage of the booster pump 20 is 28V, the working flow is 2920ml/min; when the input voltage of the booster pump 20 is 29V, the working flow rate is 3100ml/min; when the input voltage of the booster pump 20 is 30V, the operation flow rate is 3220ml/min.
It can be seen that assuming that the rated water output of the waste water valve 90 is 500ml/min, when the water consumption is 1000 ml/min, the working flow rate of the booster pump 20 is greater than 1500ml/min, then the optimum input voltage of the booster pump 20 is 17V, and when the input voltage of the booster pump 20 is 17V, the working flow rate of the booster pump 20 is 1560ml/min. When the front-mounted water purifying unit 10 or the reverse osmosis water purifying unit 30 is clogged, the input voltage of the booster pump 20 needs to be increased in order to ensure the water yield, i.e., the input voltage of the booster pump 20 needs to be greater than 17V.
In this embodiment, during the use of the water purification system, whether the front water purification unit 10 and/or the reverse osmosis water purification unit 30 are in an abnormal state or not can be judged according to the real-time value of the first pulse flow meter 50 and the real-time value of the second pulse flow meter 80, that is, whether the front water purification unit 10 and/or the reverse osmosis water purification unit 30 are in a blocking state or not is judged, if the blocking condition reaches a preset standard, the front water purification unit 10 and/or the reverse osmosis water purification unit 30 is reminded to be replaced, so that the filter element can be accurately reminded to be replaced.
