In this embodiment, the plurality of sub-positive electrodes 123a can be electrically connected to each other by a wire or other methods, and the plurality of sub-negative electrodes 124a can be electrically connected to each other by a wire or other methods, that is, the plurality of sub-positive electrodes 123a are connected in series, and the plurality of sub-negative electrodes 124a are connected in series. Each diaphragm 122a is correspondingly provided with a positive electrode 123 and a negative electrode 124, and the multiple sub positive electrodes 123a are arranged at intervals along the plane of the diaphragm 122a, and the multiple sub negative electrodes 124a are arranged at intervals along the plane of the diaphragm 122a, so that on the premise that all or most of the single diaphragm 122a is ensured to be distributed with active oxides, the wind shielding areas of the positive electrode 123 and the negative electrode 124 are reduced, the wind resistance of the electrolyzed water generating module 120 is reduced, and the air output of the whole device is improved. The plurality of sub-positive electrode elements 123a may be regularly arranged on the plane of the membrane 122a, or may be randomly arranged. The plurality of sub-negative electrode elements 124a may be regularly arranged on the plane of the membrane 122a, or may be randomly arranged.

Specifically, referring to fig. 4 to 8 again, the plurality of sub-positive electrode elements 123a are disposed at intervals along the length direction or the width direction of the membrane 122 a; and/or, a plurality of sub-negative electrode members 124a are disposed at intervals along the length direction or the width direction of the membrane 122 a. The plurality of membranes 122a are arranged in a zigzag manner, so that the long sides of the adjacent membranes 122a are connected. The longitudinal direction of the film 122a is the extending direction of the long side thereof, and the width direction of the film 122a is the extending direction of the short side thereof.

When the sub positive electrode member 123a and the sub negative electrode member 124a extend along the width direction of the diaphragm 122a, the sub positive electrode member 123a and the sub negative electrode member 124a may be disposed in a long strip, which may be a rectangular strip, an oblong strip, an arc strip, a wave strip, or the like. The long wavy sub positive electrode element 123a and the long wave negative electrode element 124a increase the area of the sub positive electrode element 123a and the sub negative electrode element 124a without affecting the air output, thereby improving the water electrolysis efficiency of the whole wet curtain 122.

In one embodiment, as shown in fig. 1 and 2, the water supply device 121 is a water tank, the bottom of the wet curtain 122 is sunk into the water tank, and two opposite peripheral sides of the wet curtain 122 form a windward side and a leeward side. In sinking into the basin through the bottom that makes wet curtain 122, wet curtain 122 adopts by the mode of supreme absorbing water down, compares in the mode that sprays for the liquid drop can not splash, avoids the noise of dripping, and can reduce the water smoke in the purification wind channel 113, makes its influence to humidity little.

The water tank may be disposed inside the cabinet 110 or outside the cabinet 110. Of course, it is also possible to provide only one water filling port connected to the water tank on the cabinet 110 to fill the water tank.

Further, referring to fig. 1, the positive electrode element 123 and the negative electrode element 124 are disposed at an interval from the water in the water tank. When the positive electrode 123 and the negative electrode 124 are located in the water tank, water in the water tank is electrolyzed, so that active oxides are generated in the water. Tests show that bacteria on the wet curtain 122 cannot be mostly removed only by allowing the wet curtain 122 to absorb water with active oxides, but not by performing electrolysis on the wet curtain 122. It indicates that the wet curtain 122 has substantially no sterilizing effect on the electrolyzed water with the active oxides absorbed. Therefore, the positive electrode element 123 and the negative electrode element 124 are spaced from the water in the water tank, so as to improve the active oxide on the wet curtain 122, and further to improve the sterilization effect of the wet curtain 122.
