[0047] Each of the anode circulation layers 4b is communicated with the second electrolysis chamber 1b, and the electrolysis cell body 1 is provided with a slightly acidic drainage channel 1f communicated with the second electrolysis chamber 1b.

[0049] Specifically, at least two electrolytic assemblies are provided, and the cathode circulation layer 4a and the anode circulation layer 4b are provided in corresponding numbers according to the number of the electrolytic assemblies. Therefore, the required number of electrolytic assemblies can be preset according to the actual production efficiency.

[0050] See also Figure 2 , in order to form a multi-layer structure design of the cathode circulation layer 4a and the anode circulation layer 4b, and to facilitate production. The electrolytic cell body 1 includes a plurality of longitudinally stacked stacked frames 11 and a cell cover 12 for closing the stacked frames 11, the stacked frames 11 are sandwiched between the two cell covers 12, so that the first electrolysis cavity 1a and the second electrolysis cavity 1b form a closed space; the stacked frame 11 is provided with a first cavity opening 111 and a second cavity opening 112, so that after the plurality of stacked frames 11 are stacked, the first electrolysis cavity 1a and the second electrolysis cavity 1b are stacked to form the first electrolysis cavity 1a and the second electrolysis cavity 1b respectively.

[0051] For details, see Figure 5 The ion membrane 3 is disposed at the first cavity opening 111 of the stacking frame 11 to close the first cavity opening 111; and by disposing the ion membrane 3, the stacking frame 11 is divided into an upper stacking part 11a and a lower stacking part 11b;

[0052] In two adjacent stacked frames 11, the cathode circulation layer 4a or the anode circulation layer 4b is formed between the lower stacked portion 11b of one stacked frame 11 and the upper stacked portion 11a of the other stacked frame 11. Therefore, due to the arrangement of the ion membrane 3, after the stacking of the plurality of stacked frames 11, a plurality of cathode circulation layers 4a and anode circulation layers 4b that are individually circulated can be formed, and they are arranged alternately in sequence.

[0053] Furthermore, in order to improve the electrolysis effect of the first electrolysis chamber 1a and the second electrolysis chamber 1b, on the stacking frame 11, a plurality of dividing strips 113 for forming a serpentine flow channel are provided at the first cavity opening 111 and the second cavity opening 112. Specifically, both ends of the dividing strip 113 are provided with water-passing notches 1131 for water to pass through, and the water-passing notches 1131 at both ends are respectively located at the upper stacking portion 11a and the lower stacking portion 11b, so that the cathode flow layer 4a or the anode flow layer 4b forms a serpentine flow channel, thereby extending the distance of water flowing through the first electrolysis chamber 1a and the second electrolysis chamber 1b, thereby extending the electrolysis time.

[0054] The electrolytic cell body 1 is provided with a cathode water collection channel 13 and an anode water collection channel 14, the cathode water inlet 1d is connected in parallel with each cathode circulation layer 4a through the cathode water collection channel 13; the anode water inlet 1e is connected in parallel with each anode circulation layer 4b through the anode water collection channel 14. With such a configuration, the user can respectively pass electrolyte of a specific formula into the cathode circulation layer 4a and\or the anode circulation layer 4b according to the production requirements of the required slightly acidic water, thereby achieving the effect of independently electrolyzing the electrolyte.

[0055] In order to realize the structural design of independent circulation and water supply between the cathode circulation layer 4a and the anode circulation layer 4b, a water collecting circulation part 15 and a water dividing circulation part 16 are respectively provided on both sides of the first cavity opening 111.

[0056] The water collecting circulation part 15 is provided with two water collecting holes 17 for respectively overlapping to form the cathode water collecting channel 13 and the anode water collecting channel 14 ; the water dividing circulation part 16 is provided with alkaline drainage holes 161 for overlapping to form the alkaline drainage channel 1 c .

[0057] At the same time, in order to avoid interference and mutual communication between the feed water of the cathode circulation layer 4a and the anode circulation layer 4b, the upper and lower end surfaces of the water collecting circulation part 15 are respectively provided with side through grooves 18, and the side through grooves 18 are respectively located in the upper stacking part 11a and the lower stacking part 11b, so as to respectively connect the cathode circulation layer 4a and the anode circulation layer 4b;

[0058] On the water collecting and circulating part 15 of the same stacking frame 11, the side through grooves 18 respectively provided on the upper stacking part 11a and the lower stacking part 11b are staggered, and the upper stacking part 11a and the lower stacking part 11b are respectively provided with the water collecting holes 17; the water collecting holes 17 of the upper stacking part 11a are connected with the side through grooves 18 of the lower stacking part 11b, and the water collecting holes 17 of the lower stacking part 11b are connected with the side through grooves 18 of the upper stacking part 11a.

[0059] For the convenience of description, according to the different structures of the water collecting and circulating part 15, the stacked frame 11 is divided into an upper frame 11A and a lower frame 11B, and the upper frame 11A and the lower frame 11B are alternately stacked in sequence;

[0060] In the two adjacent stacked frames 11 , the side through grooves 18 of the upper frame 11A and the side through grooves 18 of the lower frame 11B are arranged in mirror symmetry; between the adjacent stacked frames 11 , the end faces of the water collecting and flowing parts 15 correspond to each other and fit together to limit the water flow from between the end faces of the two adjacent water collecting and flowing parts 15 .

[0061] With such arrangement, when the upper frame 11A and the lower frame 11B are alternately overlapped in sequence, the two water collection holes 17 of the water collection circulation part 15 will overlap respectively to form the cathode water collection channel 13 and the anode water collection channel 14 which are not connected to each other, and at the same time, side through grooves 18 are respectively provided to independently flow into the cathode circulation layer 4a or the anode circulation layer 4b.

[0062] In more detail, on the upper frame 11A, the upper and lower end surfaces of the water-dividing circulation portion 16 are respectively provided with side through grooves 18, and the side through grooves 18 are respectively located in the upper stacking portion 11a and the lower stacking portion 11b, so as to respectively connect the cathode circulation layer 4a and the anode circulation layer 4b;

[0063] On the water-dividing and circulating part 16 of the same stacking frame 11, the side through grooves 18 provided on the upper stacking part 11a and the lower stacking part 11b are staggered, and the alkaline drainage hole 161 is provided on the upper stacking part 11a and communicates with the side through grooves 18 of the lower stacking part 11b correspondingly;

[0064] On the water-dividing circulation part 16 of the lower frame 11B, the upper stacking part 11a is provided with a side through groove 18 communicating with the cathode circulation layer 4a, and correspondingly communicated with the alkaline drainage hole 161 of the lower stacking part 11b of the adjacent upper frame 11A. The alkaline drainage hole 161 of the lower frame 11B is provided at the lower stacking part 11b of the water-dividing circulation part 16, and communicated with the side through groove 18 of the upper stacking part 11a. At the same time, the lower stacking part 11b is provided with a communication notch 11c to form a communication channel between the anode circulation layer 4b and the second cavity, see Figure 6 .

[0065] Therefore, when the upper frame 11A and the lower frame 11B are alternately overlapped in sequence, the alkaline drainage holes 161 will overlap to form the alkaline drainage channel 1c, thereby diverting and discharging the electrolyzed water of each cathode circulation layer 4a, and correspondingly, the electrolyzed water of each anode circulation layer 4b will flow into the second electrolysis chamber 1b through the connecting gap 11c to perform secondary electrolysis on the slightly acidic electrolyzed water.

[0066] A slightly acidic drainage portion 19 is provided on one side of the second cavity opening 112, and the upper and lower end surfaces of the slightly acidic drainage portion 19 are provided with slightly acidic side grooves 191 for communicating with the second electrolytic cavity 1b and slightly acidic holes 192 for overlapping to form the slightly acidic drainage channel 1f, and the slightly acidic holes 192 are correspondingly provided at the slightly acidic side grooves 191 to communicate with the slightly acidic side grooves 191. Therefore, the electrolyzed water in the second electrolytic cavity 1b can flow into the slightly acidic drainage channel 1f through the slightly acidic side grooves 191.

[0067] Since the stacked frame 11 is sandwiched between the two tank covers 12, the cathode water inlet 1d and the anode water inlet 1e are provided in the tank cover 12 located at the top, and the tank cover 12 located at the bottom is provided with a slightly acid output port 121 for outputting slightly acidic water to connect the slightly acidic drainage channel 1f. Correspondingly, the tank cover 12 located at the bottom is provided with an alkaline drainage port 122 connected to the alkaline drainage channel 1c. Such a high and low setting facilitates the circulation of liquid, so as to reduce the residual liquid in the first electrolysis chamber 1a and the second electrolysis chamber 1b when the work is stopped.

[0068] In order to facilitate the electrical connection between the external power supply electrode and the cathode sheet 2a and the anode sheet 2b, the upper frame 11A and the lower frame 11B are respectively provided with electrode holes 110 for connecting the conductive element 5, and after the upper frame 11A and the lower frame 11B are overlapped, the electrode holes 110 of the upper frame 11A are distributed on one side, and the electrode holes 110 of the lower frame 11B are respectively on the other side, so as to facilitate the parallel electrical connection of multiple cathode sheets 2a or anode sheets 2b through a single conductive strip 6.

[0069] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
