The bottom of the rubber sealing ring 22 abuts against the top of the deionization tank 1. On both sides of the top of the inner wall of the tank cover 2, connecting rods 23 are fixedly connected. The number of the connecting rods 23 is two. Both sides of the metal filter screen 24 are fixedly sleeved on the lower parts of the outer walls of the two connecting rods 23. The bottom ends of the two connecting rods 23 are fixedly connected to both sides of the top of the activated carbon filter screen 25.

[0021] In this embodiment, through the setting of the rubber sealing ring 22, it is convenient to increase the sealing performance between the tank cover 2 and the deionization tank 1. Through the setting of the connecting rods 23, it is convenient to fixedly install the metal filter screen 24 and the activated carbon filter screen 25 below the tank cover 2. Through the setting of the water inlet 21, it is convenient to drain water into the interior of the deionization tank 1, and through the cooperation of the metal filter screen 24 and the activated carbon filter screen 25, it is convenient to filter impurities in the water. Then, through the cation exchange resin 32 inside the first deionization cover 3 and the anion exchange resin 52 inside the second deionization cover 5, it is convenient to remove the cations and anions in the water.

[0022] Example Two:

[0023] As Figure 1-2 shown, a drain hopper 4 is fixedly connected inside the deionization tank 1. The drain hopper 4 is located between the first deionization cover 3 and the second deionization cover 5. In the middle of the bottom of the drain hopper 4, a first drain pipe 41 is fixedly connected. A first solenoid valve 42 is installed on the first drain pipe 41. The first drain pipe 41 is located above the second deionization cover 5. On the right side of the first drain pipe 41, a second drain pipe 43 is fixedly connected. One end of the second drain pipe 43 communicates with the inside of the first drain pipe 41. One end of the second drain pipe 43 is located above the first solenoid valve 42. A second solenoid valve 44 is installed on the second drain pipe 43. The other end of the second drain pipe 43 extends to the outside of the deionization tank 1. Below the right side of the deionization tank 1, there is a second water tank 8. Hydrochloric acid water is provided inside the second water tank 8. On one side of the top of the second water tank 8, a second water pump 82 is fixedly installed. The input end of the second water pump 82 is fixedly connected with a first connecting pipe 81. One end of the first connecting pipe 81 extends to the lower part of the inner cavity of the second water tank 8. The output end of the second water pump 82 is fixedly connected with a second connecting pipe 83. One end of the second connecting pipe 83 extends into the inner cavity of the deionization tank 1 and is fixedly connected with a second spray head 84. The second spray head 84 is located above the first deionization cover 3.

[0024] In this embodiment, when restoring the exchange capacity of the cation exchange resin 32, first close the first solenoid valve 42 and open the second solenoid valve 44. Then, through the cooperation of the first connecting pipe 81, the second water pump 82, the second connecting pipe 83 and the second spray head 84, it is convenient to extract the hydrochloric acid water inside the second water tank 8 and flush the cation exchange resin 32 inside the first deionization cover 3 to restore the exchange capacity of the cation exchange resin 32. Then, through the cooperation of the drain hopper 4, the first drain pipe 41 and the second drain pipe 43, the hydrochloric acid water can be discharged.

[0025] Example Three:

[0026] As Figure 1-2 shown, below the left side of the deionization tank 1, there is a first water tank 7. Alkaline water is provided inside the first water tank 7. On one side of the top of the first water tank 7, a first water pump 72 is fixedly installed. The input end of the first water pump 72 is fixedly connected with a first conduit 71. One end of the first conduit 71 extends to the lower part of the inner cavity of the first water tank 7. The output end of the first water pump 72 is fixedly connected with a second conduit 73. One end of the second conduit 73 extends into the inner cavity of the deionization tank 1 and is fixedly connected with a first spray head 74. The first spray head 74 is located above the second deionization cover 5.

[0027] In this embodiment, through the cooperation of the first conduit 71 and the first water pump 72, it is convenient to extract the alkaline water inside the first water tank 7, spray it on the second deionization cover 5 through the second conduit 73 and the first spray head 74, and flow into the second deionization cover 5 through the second through-hole 51 to wash the anion exchange resin 52, so as to restore the exchange capacity of the anion exchange resin 52, and then the alkaline water can be discharged through the drain port 6.

[0028] In summary, as Figure 1-2 shown, for this deionized water equipment, when in use, water is discharged into the deionization tank 1 through the water inlet 21, and impurities in the water are filtered through the metal filter screen 24 and the activated carbon filter screen 25. Then the water flows into the first deionization cover 3 through the first through-hole 31 and the cation exchange resin 32 adsorbs the cations in the water. Then the water is discharged into the drain hopper 4. At this time, the first solenoid valve 42 is opened, and the water is discharged above the second deionization cover 5 through the first drain pipe 41, and then flows into the second deionization cover 5 through the second through-hole 51. The anion exchange resin 52 adsorbs the anions in the water. At this time, the cations and anions in the water are removed, and then the water can be discharged through the drain port 6. When the adsorption capacities of the cation exchange resin 32 and the anion exchange resin 52 reach the saturation state, first close the first solenoid valve 42 and open the second solenoid valve 44. At this time, the hydrochloric acid water inside the second water tank 8 is extracted through the first connecting pipe 81 and the second water pump 82, and sprayed above the first deionization cover 3 through the second connecting pipe 83 and the second spray head 84. The hydrochloric acid water enters the first deionization cover 3 through the first through-hole 31 to wash the cation exchange resin 32 and restore the exchange capacity of the cation exchange resin 32. Then the hydrochloric acid water flows into the drain hopper 4 and enters the second drain pipe 43 through the first drain pipe 41, and is discharged through one end of the second drain pipe 43. At the same time, the alkaline water inside the first water tank 7 is extracted through the first conduit 71 and the first water pump 72, and sprayed on the second deionization cover 5 through the second conduit 73 and the first spray head 74, and flows into the second deionization cover 5 through the second through-hole 51 to wash the anion exchange resin 52, so as to restore the exchange capacity of the anion exchange resin 52, and then the alkaline water can be discharged through the drain port 6.
