[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 6 The present invention provides a multifunctional water purifier, comprising an outer shell 1 made of corrosion-resistant engineering plastics, a transparent observation window 11 is provided on the front of the outer shell 1, a detachable inspection cover 121 is hinged on the top of the outer shell 1, four rubber shock-absorbing pads 13 are installed on the bottom of the outer shell 1, a microcomputer controller 2 is installed inside the outer shell 1, a control panel 21 installed on the surface of the outer shell 1 is provided on the top of the microcomputer controller 2, a waterway control component 3 is also installed inside the outer shell 1, and the waterway control component 3 includes a first low-pressure switch 31 installed at the water inlet of the outer shell 1, The first low-pressure switch 31 is electrically connected to a water inlet solenoid valve 4, which is in communication with the water inlet of the outer shell 1. The water outlet of the water inlet solenoid valve 4 is connected to a filter mechanism 5, which includes a PE filter element 51 and a multi-media filter element 52. The water filtered by the filter mechanism 5 is connected to a high-pressure water pump 6 through a pipeline, and the water outlet of the high-pressure water pump 6 is connected to an RO membrane filter 7. The water outlet of the RO membrane filter 7 is connected to a three-water outlet combination nozzle 8 through a first high-pressure switch 71. The water outlet of the RO membrane filter 7 is also connected to a wastewater flushing solenoid valve 72 through a pipeline.

[0027] The three-outlet combination faucet 8 is also connected to the electrolytic cell 9 through a diverter valve 81. The reduced water after electrolysis in the electrolytic cell 9 is connected to one of the water outlets of the three-outlet combination faucet 8 through a pipeline, and the oxygen-rich disinfected water formed after electrolysis in the electrolytic cell 9 is connected to the other water outlet of the three-outlet combination faucet 8.

[0028] Specifically, when the multifunctional water purifier is used at home or in a commercial place, water first enters from the water inlet of the outer shell 1, and the first low-pressure switch 31 can monitor the water pressure in real time. When the water pressure is normal, water enters the solenoid valve 4 and sends an electrical signal to the microcomputer controller 2 to open the water inlet solenoid valve 4, and the water smoothly passes through the water inlet solenoid valve 4 into the filter mechanism 5. The PE filter element 51 in the filter mechanism 5 can intercept larger particles of impurities such as mud, rust, etc. in the water. The activated carbon, quartz sand and other filter media filled in the multi-media filter element 52 can further absorb the odor, residual chlorine and some tiny particles in the water. Then, the water that has been initially filtered is transported to the high-pressure water pump 6 through a pipeline. The high-pressure water pump 6 pressurizes the water so that the water can overcome the resistance of the RO membrane filter 7 and enter the RO membrane filter 7 for high-precision filtration. The RO membrane filter 7 can effectively intercept bacteria, viruses, heavy metal ions and other tiny impurities in the water, thereby producing high-quality pure water.

[0029] Part of the purified water is delivered to the three-outlet combined faucet 8 through the first high-pressure switch 71, and the user can directly obtain purified drinking water from here. At the same time, in order to ensure the normal operation and filtering effect of the RO membrane filter 7, another part of the purified water will be connected to the wastewater flushing solenoid valve 72 through a pipeline to flush the RO membrane when necessary, to prevent impurities from accumulating on the surface of the RO membrane and extend the service life of the RO membrane.

[0030] The three-outlet combination faucet 8 is also connected to the electrolytic cell 9 through a diverter valve 81. When the user has a demand, part of the pure water will flow into the electrolytic cell 9. In the electrolytic cell 9, the water is decomposed into reduced water and oxygen-enriched disinfected water through electrolysis. The reduced water is connected to one of the water outlets of the three-outlet combination faucet 8 through a pipeline again, and the oxygen-enriched disinfected water is connected to the other water outlet of the three-outlet combination faucet 8. Subsequently, the user can use the three-outlet combination faucet 8 to easily discharge pure water, reduced water or oxygen-enriched disinfected water according to the needs of different scenarios to meet the usage needs of different users.

[0031] During the operation of the equipment, each electrical component can be intelligently controlled through the microcomputer controller 2. The microcomputer controller 2 receives electrical signals from the first low-pressure switch 31, the first high-pressure switch 71 and other components, and accurately controls the operation of the water inlet solenoid valve 4, the high-pressure water pump 6, the wastewater flushing solenoid valve 72 and other components according to the preset program to ensure that the water purifier works stably and efficiently. The control panel 21 is convenient for user operation, and different functional water can be selected according to actual needs to be discharged through the three-outlet combination nozzle 8.

[0032] In this embodiment, a heat dissipation hole 101 is opened in the outer shell 1 at the electrolytic cell 9 , and a roller 102 with a wheel brake is installed at the bottom of the outer shell 1 , and a three-outlet combined nozzle 8 is located outside the outer shell 1 .

[0033] Specifically, during the operation of the electrolytic cell 9, the heat dissipation holes 101 can enable air to form convection inside and outside the outer shell 1, dissipate the heat generated by the electrolytic cell 9 in time, and ensure that the electrolytic cell 9 works stably under a suitable temperature environment. The roller 102 with a wheel brake greatly improves the maneuverability and convenience of the device, making it convenient for users to move the device.

[0034] In this embodiment, the filter mechanism 5 also includes a filter box 53, the PE filter element 51 and the multimedia filter element 52 are both installed inside the filter box 53, and the water inlet and outlet of the filter box 53 are connected to the water inlet solenoid valve 4 and the high-pressure water pump 6 respectively.

[0035] Specifically, after water flows out from the water inlet solenoid valve 4, it directly enters the water inlet of the filter box 53, and then the PE filter element 51 can quickly intercept larger granular impurities visible to the naked eye in the water. The water that has been initially filtered by the PE filter element 51 enters the multi-media filter element 52. The multi-media filter element 52 is filled with various filter media such as activated carbon and quartz sand, which can efficiently absorb residual chlorine, odor and some organic pollutants in the water. The water that has been double filtered by the PE filter element 51 and the multi-media filter element 52 is extracted and pressurized by the high-pressure water pump 6. After the high-pressure water pump 6 is pressurized, it can ensure that the water enters the RO membrane filter 7 with sufficient power for deeper filtration, thereby improving the water purification quality of the entire water purifier and providing users with safer and healthier drinking water.

[0036] In this embodiment, the multi-media filter core 52 is filled with activated carbon, quartz sand and other filter media, and the filter mechanism 5 and the RO membrane filter 7 are both installed inside the outer shell 1 .

[0037] Specifically, the activated carbon, quartz sand and other filter media filled in the multimedia filter element 52 can efficiently adsorb residual chlorine, organic matter and some heavy metal ions in the water by utilizing the rich microporous structure of the activated carbon. The water preliminarily purified by the multimedia filter element 52 continues to enter the RO membrane filter 7. The RO membrane filter 7 adopts high-precision reverse osmosis technology. Its pore size is very small, and only water molecules are allowed to pass through. Bacteria, viruses, heavy metal ions and other tiny impurities can be intercepted on one side of the RO membrane. Under the pressure provided by the high-pressure water pump 6, water is forced to pass through the RO membrane, thereby achieving efficient separation of water and impurities, thereby producing pure water with extremely high purity.

[0038] In this embodiment, the electrolytic cell 9 is respectively connected to a second low-pressure switch 91 and a second high-pressure switch 92. The second low-pressure switch 91, the high-pressure switch 92 and the first low-pressure switch 31 are all electrically connected to the microcomputer controller 2. The second low-pressure switch 91 and the second high-pressure switch 92 are respectively connected to the water supply pipes of the three-outlet combination faucet 8 and the electrolytic cell 9.

[0039] Specifically, when the water purifier is working, when water flows from the three-outlet combined water nozzle 8 to the electrolytic cell 9 through the diverter valve 81, the second low-pressure switch 91 detects the water pressure in real time. When the water pressure is too low, the electrolytic cell 9 may not work properly. At this time, the second low-pressure switch 91 sends a signal to the microcomputer controller 2. After receiving the signal, the microcomputer controller 2 takes corresponding measures according to the preset program, and can suspend the operation of the electrolytic cell 9. At the same time, an alarm may be issued through the control panel 21 to prompt the user to inform that the water pressure is abnormal and the water inlet needs to be checked;

[0040] When the water pressure is too high, in order to avoid damage to the electrolytic cell 9, once the second high-pressure switch 92 detects that the water pressure exceeds the safety threshold, the second high-pressure switch 92 will also send a signal to the microcomputer controller 2. The microcomputer controller 2 will immediately respond by adjusting the opening of the water inlet solenoid valve 4, reducing the water flow entering the electrolytic cell 9, ensuring that the water pressure returns to a normal range, protecting the electrolytic cell 9 from damage by excessive water pressure, and effectively ensuring the service life of the water purifier.

[0041] In this embodiment, a power supply assembly 10 is also included. The power supply assembly 10 is a 24V safety power supply with overcurrent and overvoltage protection functions. A power box 15 is installed inside the outer shell 1, and the microcomputer controller 2, the first low-pressure switch 31, the water inlet solenoid valve 4, the high-pressure water pump 6, the first high-pressure switch 71, the wastewater flushing solenoid valve 72 and the electrolytic cell 9, the second low-pressure switch 91 and the second high-pressure switch 92 are electrically connected. The power supply assembly 10 is also electrically connected to an external power supply.

[0042] Specifically, when the water purifier is connected to an external power source, the power supply assembly 10 starts to work, converting the external input power into the 24V safe voltage required by the various components of the device, and providing them with a stable power supply. During the operation of the device, if the current is too large, the power supply assembly 10 can automatically cut off the circuit to prevent the excessive current from damaging sensitive components such as the microcomputer controller 2 and the high-pressure water pump 6. At the same time, when the voltage is detected to be too high, the overvoltage protection function of the power supply assembly 10 can prevent the excessive voltage from breaking through the electronic components, ensuring the safety of various components of the device.

[0043] In this embodiment, a water quality monitoring sensor group 14 is also included. The water quality monitoring sensor group 14 consists of a residual chlorine sensor 141, a TDS sensor 142 and a pH sensor 143. The residual chlorine sensor 141, the TDS sensor 142 and the pH sensor 143 are all electrically connected to the microcomputer controller 2. The residual chlorine sensor 141 is connected to the water outlet pipeline of the PE filter element 51, the TDS sensor 142 is connected to the water outlet pipeline of the RO membrane filter 7, and the pH sensor 143 is connected to the pipeline of the reduced water outlet of the electrolytic cell 12.

[0044] Specifically, the residual chlorine sensor 141 can detect the residual chlorine content in the water after preliminary filtration and transmit the data to the microcomputer controller 2. When it is detected that the residual chlorine content exceeds the normal range, the microcomputer controller 2 will shut down according to the preset program or remind through the control panel 21;

[0045] The TDS sensor 142 can be used to measure the total amount of dissolved solids in water. The TDS sensor 142 feeds back the detected TDS value to the microcomputer controller 2 in real time. When the TDS value is too high, the filtering effect of the RO membrane filter 7 may be problematic. The microcomputer controller 2 will control the wastewater flushing solenoid valve 72 to flush the RO membrane, or prompt the user to check or replace the RO membrane to ensure that the produced pure water has a high degree of purity.

[0046] The pH sensor 143 is connected to the pipeline at the outlet of the reduced water of the electrolytic cell 9, and can monitor the pH value of the reduced water in real time. The pH sensor 143 transmits the detected pH value information to the microcomputer controller 2. The microcomputer controller 2 can adjust the pH value of the reduced water by adjusting the electrolysis parameters of the electrolytic cell 9 according to actual needs to meet the diverse needs of users. Then, through the coordinated work of multiple sensors, the multifunctional water purifier can grasp the water quality status in real time to ensure that users are provided with safe, high-quality functional water that meets diverse needs.
