Under the instructions of the control module, the first three-way reversing valve 411 and the second three-way reversing valve 405 can control the opening and closing of the pipeline and change the flow direction of the water in the pipeline, thereby switching the device between normal working mode and backwash mode.

[0046] See Figures 4 to 7When using the present invention, first open the cover 200 near the water storage box 402, connect the water outlet pipe 5 to the water storage box outlet 4011, extend the end of the water inlet pipe 300 without the pre-filter 301 into the water inlet 102 and insert it into the motor inlet 4141, then extend the pre-filter 301 into the seawater, extend the wastewater pipe 1051 into the wastewater outlet 105 and install it on the wastewater outlet 4073, turn on the switch 103, and the various components in the present invention start working. The seawater is first filtered through the pre-filter 301 to filter out large insoluble particles. The seawater then reaches the nuclear radiation detector 302 for radiation value detection and radionuclide judgment. The nuclear radiation detector 302 transmits the measured data to the data processing module and the judgment module in the single chip microcomputer. If the judgment module finds that the radioactivity of the seawater exceeds the standard or the concentration of the radionuclide exceeds the standard, it sends a prompt message to the external device through the wireless transmission module to remind the user to pay attention. The seawater then flows into the water inlet pipe 300, enters the motor 414 through the motor inlet 4141, and then the water The water is output from the motor outlet 4142 and enters the first three-way reversing valve 411. The other channels of the first three-way reversing valve 411 are closed, and only the channel to the filter cartridge storage tank 407 is opened. The seawater enters the filter cartridge storage tank 407 through the tank cover water inlet 40711. After being filtered by the filter cartridge 6 in the filter cartridge storage tank 407, the produced water flows out from the water production port 4072 and enters the second three-way reversing valve 405. The other directions of the second three-way reversing valve 405 are closed, and only the direction to the third pipe 403 is opened. The produced water flows through the third pipe 403 and flows through the water storage box inlet 402. 1 enters the water storage box 402, and the wastewater generated by filtration enters the filter element storage tank 407 and is then discharged through the wastewater pipe 1051 connected to the wastewater outlet 4073; the pH sensor and TDS sensor provided in the water storage box 402 detect the quality of the filtered water in real time and transmit the data to the data processing module and judgment module in the single-chip microcomputer. If it is found that the pH or TDS content of the water in the water storage box 402 does not meet the requirements, a prompt message is sent to the external device through the wireless transmission module to remind the user to pay attention and, if necessary, remind the user to start the backwash mode or replace the filter element 6.

[0047] See Figure 5 、 Figure 7After the user receives the related reminder of backwashing, the filter element 6 of the present invention should be backwashed. The user can also start backwashing on his own. In the backwashing mode, first extend the waste water pipe 1051 into the waste water outlet 105 and install it on the waste water outlet 4073, turn on the switch 103, and the user needs to put the water inlet pipe 300 into clean water, and then send a backwashing mode start signal to the single chip microcomputer through the external device. Clean water will flow into the motor 414 through the water inlet pipe 300, and then the first three-way reversing valve 411 will close other pipes, leaving only the second pipe 408 connected to the second three-way reversing valve 405. Clean water will flow to the second three-way reversing valve 40 5. At this time, the second three-way reversing valve 405 will close other channels and only open the pipeline leading to the filter element storage tank 407, specifically the first pipeline 410. At this time, clean water flows into the filter element 6 from the water outlet 4072 to start cleaning the filter element 6. The waste water after cleaning will enter the filter element storage tank 407 like the waste water generated when the filter element 6 works normally. As the waste water fills the filter element storage tank 407, the only outlet of the filter element storage tank 407 is the waste water outlet 4073, and the waste water is discharged from the waste water pipe 1051.

[0048] When the user needs to disassemble the present invention, the user can lift up each limit bar 1041 at the same time to take out all the internal parts in the shell 100 at the same time; when the user needs to install the internal parts back, each component needs to be installed on the corresponding limit groove 10411 on the limit bar 1041 first, and then pull up each limit bar 1041 at the same time and put it into the shell 100 to install all the internal parts into the shell 100.

[0049] Although the present invention is designed for the purification and desalination of seawater, it obviously has the potential to be applied to the desalination of other water bodies such as saltwater lakes. In short, the beneficial effects of the present invention are: 1. It is compact in size and designed to be the size of a thermos cup, easy to carry, and suitable for use outdoors, traveling or in emergencies. 2. It integrates a variety of sensors, and the data of the sensors can be input into the single-chip microcomputer for processing and then sent to external devices.
