The technical solution of the present invention will be described in detail with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

FIG. 1 is a schematic diagram of a filter of an electrochemical water treatment system according to an embodiment of the present invention; fig. 2 is a first schematic view of a filter of an electrochemical water treatment system according to an embodiment of the present invention.

Referring to fig. 1 and 2, the filter 1 includes a housing 11, a filter bag clamp 12 and a filter bag 13 disposed in the housing 11, the filter bag 13 is clamped in the filter bag clamp 12, and the filter bag clamp 12 is connected in the housing 11. The clamping of the filter bag 13 by the filter bag clamp 12 is understood to mean that the filter bag 13 is clamped in its entirety.

Simultaneously, the usable water inlet 14 of filter 1 is to outer being connected with delivery port 15, in the concrete implementation: the water inlet 14 may be connected to the basin 3 and the water outlet 15 may be connected to the water usage system 4. Meanwhile, the water inlet 14 and the water outlet 15 may be respectively located at two sides of the filter bag 13, for example, may be located at the upper and lower sides as shown in the figure, and after water enters from one side of the filter bag 13, the filtered water may be sent out from the other side of the filter bag 13 and the water outlet 15 by filtering through the filter bag 13.

The filter bag holder 12 according to the present embodiment may have any structure capable of holding the filter bag 13 so as to maintain the overall shape of the filter bag 13 from being changed by the flow of water or gas. Thus, it is advantageous that the filter bag 13 can be maintained in an arbitrary configuration, so that the filtering capacity can be kept constant, and further, it is advantageous that the filtering capacity is always kept maximum when the filter bag is opened to the maximum in the filter bag holder. In the following embodiments of the present embodiment, the cleaning is performed by using the instantaneous pressure difference, and the filter bag clamp 12 is used to clamp the whole filter bag 13, so that the form of the filter bag 33 is prevented from being changed by the pressure difference.

In conventional practice, bag-type filter elements, such as filter bags, in a filter are usually cleaned by introducing a reverse flow of liquid or gas to flush the filter bags, however, filter bags cleaned by flushing are often difficult to achieve the desired cleaning result, which results in replacement of the filter bags after a period of use (e.g. one week), and consequently, a shorter service life of the filter bags.

In a specific implementation process, the water inlet 14 and the air outlet 16 are located at one side of the filter bag 13, and the water outlet 15 and the air inlet 17 are located at the other side of the filter bag. Further, the direction of ventilation and the direction of water flow can be reversed, thereby facilitating the discharge of impurities by the reverse flow of gas.

It will be seen that in the above embodiments, different sink portions may be selectively filtered, and that the filtered water may be used for return to the water system.

Meanwhile, although fig. 8 illustrates the first and

second water tanks
