Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0023] like Figure 1-4As shown, an electric control system of a water purifier capable of adjusting the components in filtered water comprises a housing 1, in which a water inlet solenoid valve 2 for controlling the on-off of tap water input, a water pump 3 for controlling the input flow rate of tap water, a first filter assembly 4 for filtering impurities in water, a second filter assembly 5 for sterilizing and disinfecting water bodies, a third filter assembly 6 for intercepting organic matter, heavy metals and trace elements in water and generating waste water for discharge, a pressure sensor 7 for detecting the output pressure of filtered water, a supplementary water pipe 8 is connected between the output end of the second filter assembly 5 and the output end of the filtered water of the third filter assembly 6 so that the filtered water retains part of the trace elements in the water, a waste water solenoid valve 9 is connected to the waste water outlet end of the third filter assembly 6, and the housing 1 is provided with a main control assembly 10 respectively connected to the water inlet solenoid valve 2, the water pump 3, the pressure sensor 7 and the waste water solenoid valve 9 to control the opening of the water inlet solenoid valve 2 and the waste water solenoid valve 9 when the water purifier is working and to control the operation of the water pump 3 to adjust the input flow rate of tap water according to the detection signal of the pressure sensor 7. In actual use, the main control component 10 controls the water inlet solenoid valve 2 and the waste water solenoid valve 9 to open, and controls the water pump 3 and the pressure sensor 7 to work, so that tap water enters through the water inlet solenoid valve 2, and is filtered and outputted through the first filter component 4, the second filter component 5 and the third filter component 6 in sequence. At this time, part of the filtered water filtered by the second filter component 5 is outputted to the third filter component 6 through the supplementary water pipe 8, and is mixed with the filtered water filtered by the third filter component 6 and then outputted, so that the filtered water retains the trace elements in the tap water, and the waste water generated by the third filter component 6 is discharged through the waste water solenoid valve 9. In this process, the pressure sensor 7 detects the water pressure of the mixed filtered water in real time, and the main control component 10 controls the water pump 3 to work and adjust the tap water input water pressure according to the water pressure, so that the filtered water outputted through the supplementary water pipe after filtering by the second filter component and the filtered water filtered by the third filter component can achieve a dynamic balance in the ratio, so as to prevent the third filter component from filtering and processing enough filtered water when the water pressure is too low and mixing with the filtered water processed by the second filter component.

[0024] like Figure 2 As shown, a small molecule water activator 11 connected to the main control component 10 is connected between the water inlet solenoid valve 2 and the water pump 3 and is used to convert the water body into small molecule cluster water. The tap water is converted into small molecule cluster water to facilitate subsequent filtration and better filter impurities, microorganisms, viruses, organic matter, heavy metals and other impurities in the water.

[0025] like Figure 3As shown, a flow meter 12 connected to the main control component 10 is connected between the third filter component 6 and the pressure sensor 7, and is used to count the output flow of filtered water, so as to determine whether the filter component needs to be replaced; the main control component 10 is connected to a filter component replacement prompt light 13 arranged on the outer shell 1, which prompts the replacement of the filter component through different color lights according to the statistical data of the flow meter 12. When the cumulative output flow of filtered water counted by the flow meter 12 reaches a preset value, the main control component 10 controls the filter component replacement prompt light 13 to change the light color to prompt the replacement of the filter component, such as displaying white light when the filter component does not need to be replaced, and displaying yellow light or red light when the filter component needs to be replaced.

[0026] like Figure 4 As shown, the main control component 10 is connected to a key panel 14 arranged on the housing 1 for inputting switch instructions and flow calculation reset instructions. A working status indicator light 15 is provided on the key panel 14. The water purifier switch is controlled by the keys on the key panel 14, and the flow meter is reset and recalculated after the filter element component is replaced. At the same time, the working status indicator light 15 is used to display the corresponding status; the key panel 14 is provided with a USB interface 16 for communicating with the main control component 10, which is used to burn the program to the main control component 10.

[0027] like Figure 1 As shown, the main control component 10 is connected to a water leakage detection plate 17 arranged on the inner bottom surface of the shell 1 for detecting whether there is a water leakage. When a water leakage occurs and water accumulates at the bottom of the shell 1, the water leakage detection plate 17 is turned on and sends a water leakage signal to the main control component 10, and the main control component 10 performs power-off and shutdown protection.

[0028] like Figure 4 As shown, a flow regulating valve 18 for regulating the water flow is provided on the supplementary water pipe 8. The flow regulating valve 18 is provided to regulate the filtered water flow of the supplementary water pipe 8, thereby regulating the trace element components of the region in the filtered water. In this case, the flow regulating valve 18 can also be an electrically controlled flow regulating valve connected to the main control component 10. The main control component 10 can control the water pump 3 and the electrically controlled flow regulating valve according to the water pressure, and can more accurately control the dynamic ratio between the mixed filtered water, accurately regulate the trace element components of the region in the filtered water, and can also adjust the electrically controlled flow regulating valve through the key panel 14.

[0029] like Figure 4 As shown, the filtered water outlet end of the third filter component 6 is connected to at least one fourth filter component 19 for filtering impurities in the water. The fourth filter component 19 is provided with water-soluble trace elements. By setting the fourth filter component 19, trace elements required by the user such as iodine are added to the filtered water.

[0030] In this case, the first filter component is a carbon fiber filter element, the second filter component is an ultrafiltration filter element, the third filter component is an RO membrane or nanofiltration filter element, and the fourth filter component is a carbon fiber filter element.

[0031] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
