The collar 208 is made of an insulating material, the housing 201 is made of an insulating material, and the diameter of the through hole of the second pole plate 203 is preferably larger than the diameter of a part of the screw of the first bolt 206, because the bolt and the pole plate are made of a conductive material, when the first bolt 206 passes through the through hole of the second pole plate 203, the first bolt 206 and the second pole plate 203 are insulated and cannot be electrically connected, so that the first bolt 206 is only electrically connected with the first pole plate 202. Specifically, the screw of the first bolt 206 is disposed at the center of the through hole corresponding to the second pole plate 203, and an annular gap 207 is maintained between the outer wall of the screw and the inner wall of the corresponding through hole, the range of the gap 207 is 0.3-5mm, in this embodiment, the gap is 0.5mm, so that after two poles of the dc power supply are electrically connected to the first pole plate 202 and the second pole plate 203 respectively, an electrical insulation is formed between the outer wall of the screw and the inner wall of the through hole of the second pole plate 203, a short circuit phenomenon of power supply between the two pole plates is not caused, and normal operation of the two pole plates is realized.

The first bolt 206 and the second bolt 214 for supplying power to the two plates are preferably disposed near the middle of the two plates, and a distance is maintained between the two bolts, and the distance is in a range of 30mm to 230mm, and the distance in this embodiment is 55 mm.

Furthermore, a first gasket 209 and a second gasket 210 are further inserted into the inner and outer wall surfaces of the housing 201 through which the first bolt 206 and the second bolt 214 are inserted, and when the first bolt 206 and the second bolt 214 are screwed by nuts, the first gasket 209 is pressed between the second pole plate 203 and the inner wall surface of the housing 201, and the second gasket 210 is pressed between the first nut 213 and the outer wall surface of the housing 201, thereby sealing the portion of the bolt inserted into the housing and preventing water in the water treatment chamber from leaking from the through hole of the housing 201. The first seal ring 209 and the second seal ring 210 are preferably an elastomeric material such as rubber, silicone, or the like.

Further, a plurality of fixing bolts 286 are included, screws of the fixing bolts 286 sequentially pass through the through holes of the first pole plate 202, the collar 208, the through hole of the second pole plate 203 and the through hole of the shell 201, a part of the screws of the fixing bolts 286 extending out of the shell 201 is matched with the first nuts 213, and nuts of the fixing bolts 286 fix the first pole plate 202 and the second pole plate 203 on one side of the shell 201 by tightening the first nuts 213; at the same time, the nuts of the fixing bolts 286 press against the first plate 202, and one end of the collar 208 abuts against the first working surface of the first plate 202, and the other end abuts against the second working surface of the second plate 203, and defines the distance therebetween. The fixing bolt 286 penetrates through the inner wall surface and the outer wall surface of the shell 201 and is further provided with a first sealing ring 209 and a second sealing ring 210 in a penetrating mode, when the fixing bolt 286 is screwed down, the second pole plate 203 and the inner wall surface of the shell 201 squeeze the first sealing ring 209, therefore, the bolt penetrates through the shell to be sealed, and water in the water treatment cavity is prevented from leaking from the through hole of the shell 201. The first seal ring 209 and the second seal ring 210 are preferably an elastomeric material such as rubber, silicone, or the like. The plurality of fixing bolts 286 are not connected to a power source and are uniformly distributed on the surface of the plate, and in the embodiment, 6 fixing bolts 286 pass through the collar 208 with the same height, so that the distance between the first plate and the second plate is defined as the height of the collar 208.

When the first plate 202 and the second plate 203 are respectively connected to the positive electrode and the negative electrode of the dc power supply, it can be known from the principle of electrolytic reaction that the reduction reaction on the first plate 202 electrically connected to the positive electrode of the dc voltage generates a strong corrosion action, so as to generate a strong corrosion action on the first plate 202 and the first bolt 206 and the fixing bolt 286 electrically connected to the plate, and therefore the first bolt 206 and the fixing bolt 286 are also made of the same corrosion-resistant material as the plate, such as titanium.

In another embodiment, when the first plate 202 and the second plate 203 are respectively connected to the negative electrode and the positive electrode of the dc power supply, it can be known that the second bolt 214 is also made of the same corrosion-resistant material as the plates, such as titanium, and the first plate 202 and the second plate 203 are connected to the positive electrode and the negative electrode of the dc power supply, respectively, at this time, only one bolt of the second bolt 214 needs to be made of the corrosion-resistant material, and it is not necessary to select the corrosion-resistant material for the bolts of the first bolt 206 and the fixing bolt 286 as in the above scheme, and since the bolt cost of the corrosion-resistant material is higher than that of a common bolt, the cost of the whole water treatment apparatus 200 can be reduced by this scheme.

Further, in another embodiment, an escape through hole 215 is formed at a position opposite to a nut of the second bolt 214 for fixing the second plate 203 to the first plate 202, as shown in fig. 6 to 8, according to the principle of water electrolysis reaction, if the distance between two plates for connecting two poles of the dc power supply is smaller, the larger the electrolytic reaction between the two plates is, the more bubbles are generated, and the distance between the nut of the second bolt 214 and the first plate 202 is smaller than the distance between the first plate 202 and the second plate 203, so that the nut of the second bolt 214 is more likely to generate the electrolytic water reaction, and thus the corrosion effect on the second bolt 214 is large, at this time, the relative distance between the nuts of the first plate 202 and the second bolt 214 can be increased by the escape through hole 215, so as to reduce the depth of the electrolytic water reaction, the diameter of the through hole 18 is preferably larger than the diameter of the nut of the second bolt 214, the relative distance is further increased, and the water electrolysis reaction effect is further reduced, so that the corrosion effect is reduced, and the service life of the bolt is prolonged.

Further, the water treatment device 200 further comprises a water pump 220, and water flow formed by a water inlet pipe and a water outlet pipe of the water pump 220 accelerates the water flow of the liquid channel between the plates.

If the partition plate 217 is not arranged, the water flow speed from the vicinity of the water outlet pipe of the water pump 220 is high, and the water flow speed of the surrounding area is low, so that the water flow entering the two polar plates is not uniform, and the accelerated rising of bubbles on the two polar plates is influenced.
