Description

Technical Field

[0001] This invention relates to the field of washing and care technology, and more specifically, to a microbubble electrolysis device. Background Technology

[0002] Micro- and nanobubbles are tiny bubbles that generate enormous energy during their collapse. This energy can disrupt the chemical bonds within pollutants, resulting in a sterilizing and purifying effect. They are used in fruit and vegetable washing, skin cleaning, and river wastewater treatment. Currently, micro- and nanobubble generation mainly involves physical methods (dissolved gas release – micro- and nanobubbles are air) and chemical methods (electrolysis of water – micro- and nanobubbles are hydrogen). Physical methods are more widely used in industry, but the systems are relatively complex and the structures are relatively large. Electrolysis of water generates micro- and nanobubbles with a relatively simple structure: the anode produces active species, and the cathode produces hydrogen micro- and nanobubbles. However, existing electrode structures are mostly planar (plate-like), leading to low utilization rates of the anode and cathode, thus preventing optimal results. Summary of the Invention

[0003] The problem solved by this invention is that, in the prior art, the electrode structures for generating micro- and nano-bubbles are basically planar relative structures (plate type), resulting in low utilization of the anode and cathode and relatively poor micro- and nano-bubble generation effect.

It should be noted that in the present application, either the first electrode 1 or the second electrode 2 is a cathode, and the other is an anode.

[0040] As an optional embodiment, a support 4 is further included, which comprises a bottom plate 44 and a side plate 45, and the bottom plate 44 and the side plate 45 surround a cavity with an opening, and the electrode assembly formed by the first electrode 1, the second electrode 2 and the insulating piece 3 is at least partially arranged in the cavity.

[0043] In one example, the first sealing piece 5 and the second sealing piece 6 are made of rubber.

[0044] In another example, the first sealing piece 5 and the second sealing piece 6 are made of epoxy resin and are arranged in the first through hole 42 and the second through hole 43 by glue pouring sealing.

[0045] In addition, optionally, the first pin 12 and the first electrode 1 are in a separate connection structure or are integrally formed, and the second pin 22 and the second electrode 2 are in a separate structure or are integrally formed.

[0047] In some examples, the first electrode 1 and the second electrode 2 are in a mesh or a complete plate or a perforated plate structure. It should be noted that the complete plate structure is a complete plate structure, and the perforated plate structure has a plurality of through holes.

[0048] In some examples, the first electrode 1 and the second electrode 2 are in a mesh or a complete plate or a perforated plate structure. It should be noted that the complete plate structure is a complete plate structure, and the perforated plate structure has a plurality of through holes.

When the first electrode 1 is closer to the bottom plate 44, the support ribs 41 or point support structures are used to support the first electrode 1, and when the second electrode 2 is closer to the bottom plate 44, the support ribs 41 or point support structures are used to support the second electrode 2.
