[0036] In specific implementation, the above design has the following effects: when filtering the water source through the filter bottle 5, it can be filtered through either the first filter element 1 or the second filter element 2.

[0041] In addition, as another embodiment of the present invention, refer to Figure 3, including a filter bottle 5, a second water supply central tube 3 is arranged at the axis of the filter bottle 5, a first water outlet 302 is arranged on the front of the second water supply central tube 3, a plurality of electric adsorption membrane intermediate isolation covers 4 are arranged in a linear array on the outer wall of the second water supply central tube 3, a first filter element 1, a second filter element 2, a third filter element 7, a fourth filter element 8, etc. are sleeved on the outer wall of the second water supply central tube 3, the electric adsorption membrane intermediate isolation cover 4 is inserted between the first filter element 1, the second filter element 2, the third filter element 7 and the fourth filter element 8, the top of the filter bottle 5, the corresponding positions of the first filter element 1, the second filter element 2, the third filter element 7 and the fourth filter element 8 are all provided with an inlet 9, the corresponding positions of the second water supply central tube 3 in the first filter element 1, the second filter element 2, the third filter element 7 and the fourth filter element 8 are all provided with an outlet 901, a total outlet 902 is arranged on the right side of the second water supply central tube 3, and a membrane cover 12 is arranged on the right side of the first filter element 1 and the left side of the fourth filter element 8.

[0042] By adopting the above design, when the filter element is replaced, other filter elements have a longer regeneration time. By extending the regeneration time, the regeneration effect is improved, thereby increasing the single use time of each filter element.

[0043] Working principle:

[0044] When in use, the water source enters the first filter element 1 or the second filter element 2 for forward power filtration according to the selected first water inlet 501 and the second water inlet 502. Alternatively, the water source selects the first water inlet 501 and the second water inlet 502 at the same time, and enters the first filter element 1 or the second filter element 2 at the same time, and the first filter element 1 and the second filter element 2 are forward powered and filtered at the same time.

[0045] Example 1

[0046] The first filter element 1 and the second filter element 2 simultaneously perform the process of forward power filtration and water production.

[0047] The water source selects the first water inlet 501 and the second water inlet 502 at the same time, and enters the first filter element 1 or the second filter element 2 at the same time, and the first filter element 1 and the second filter element 2 perform forward power filtration at the same time.

[0048] That is, the first central tube electrode lead 105, the first membrane electrode lead 106, the second central tube electrode lead 205, and the second membrane electrode lead 206 in the first filter element 1 and the second filter element 2 are energized. The product water of the first filter element is connected to the first central tube outlet hole 104, and the product water of the second filter element is connected to the second central tube outlet hole 204. After being collected, the product water flows out of the filter bottle through the second outlet 302 and the outlet 505.

[0049] Example 2

[0050] The first filter element 1 is energized in the forward direction to filter and produce water, while the second filter element 2 is energized in the reverse direction to filter and regenerate.

[0051] The first filter element 1 and the second filter element 2 are simultaneously powered forward to filter and produce water, and the time set by the control system is reached:

[0052] The first filter element 1 continues to be energized in the forward direction to filter and produce water, that is, the first central tube electrode lead 105 and the first membrane body electrode lead 106 in the first filter element 1 are energized in the forward direction (106 is positive, 105 is negative) to adsorb electrolyte and filter and continue to produce water.

[0053] The second filter element 2 is reversely powered, that is, the second central tube electrode lead 205 and the second membrane electrode lead 206 in the second filter element are reversely powered (206 is negative and 205 is positive), and the electrolyte is discharged by reverse power supply for regeneration.

[0054] The second filter element 2 is reversed and powered on for regeneration until the set time, and then powered on in the forward direction to filter and produce water, and then the first filter element 1 is reversed and powered on for regeneration.

[0055] The reciprocating cycle can realize the rapid switching of the filter element of the device, which not only facilitates the cleaning of the filter element, but also will not delay the progress of the filtering operation.
