[0029] Example 1:

[0030] This embodiment provides a flow-through water electrolysis structure, such as... Figures 1-7 As shown, it includes an outer shell 1 and two electrode plates 7. An electrolysis chamber 15 is provided inside the outer shell 1. The two electrode plates 7 are arranged parallel to each other in the electrolysis chamber 15. Water is electrolyzed when it flows between the two electrode plates 7.

[0031] An inlet 2 and an outlet 3, communicating with the electrolysis chamber 15, are respectively provided at both ends of the outer shell 1. An inlet channel 12, arranged along a first direction x, is provided inside the outer shell 1 near the inlet 2. The inlet 2 is connected to the inlet channel 12, and the water flow direction at the inlet 2 is the same as the water flow direction within the inlet channel 12 to reduce water inlet resistance. Multiple inlet holes 13, arranged along a second direction y, are provided on the side of the inlet channel 12 near the electrolysis chamber 15, and these holes are parallel to each other. The inlet holes 13 are distributed along the first direction x. The inlet channel 12 communicates with the electrolysis chamber 15 through the multiple inlet holes 13. Preferably, the outer shell 1 has a rectangular structure, where the first direction x is the width direction of the outer shell 1, and the second direction y is the length direction of the outer shell 1. The water flows through the length direction of the outer shell 1 in the electrolysis chamber to increase the flow path, increase the electrolysis time, and improve the electrolysis efficiency.

[0032] In this embodiment, the flow-through water electrolysis structure connects the inlet 2 to the municipal tap water supply. The tap water flows in through the inlet 2 of the outer casing 1, passes through the inlet channel 12 within the casing, and is then distributed through multiple inlet holes 13 into the electrolysis chamber. Multiple water flows parallel to each other, passing over the electrode plates for electrolysis, and finally converges at the outlet and flows out through the outlet 3. The flow-through water electrolysis structure of this embodiment employs a multi-channel parallel design, ensuring even distribution of the incoming water across the electrode plates, resulting in more complete electrolysis of the tap water and a higher concentration of disinfectant water after electrolysis. Compared to existing single-channel modules, the concentration is approximately 20% higher.

[0033] As a preferred embodiment, such as Figure 4 and Figure 6 As shown, multiple water inlet holes 13 are evenly distributed along the water inlet channel 12, and the diameter of the multiple water inlet holes 13 gradually increases from the side closer to the water inlet 2 to the side farther away from the water inlet 2. In this embodiment, by setting water inlet holes 13 of different sizes, the water flow can be evenly distributed into the electrolysis chamber 15 according to the size of the water inlet hole 13, so that the water flow distribution in the first direction x is more uniform, further improving the uniformity of water flow distribution in the electrolysis chamber 15 and improving electrolysis efficiency.

[0034] In a preferred embodiment, the centers of the plurality of water inlets 13 are directly opposite the two electrode plates 7. The two electrode plates 7 have equal areas, and the centers of the plurality of water inlets 13 are directly opposite the two electrode plates 7, which allows multiple streams of water to flow fully between the two electrode plates 7 and be fully electrolyzed by the two electrode plates 7, thereby improving the electrolysis efficiency of the water and producing disinfected water that meets the standards.

[0035] As a preferred embodiment, such as Figures 4-6 As shown, the outer casing 1 has a first side 16 and a second side 17 on opposite sides in the first direction x. Two parallel slots 14 are respectively provided on the first side 16 and the second side 17 inside the outer casing 1. The slots 14 extend along the second direction y, and the two electrode pieces 7 are respectively engaged in the slots 14.

The slots 14 have an opening near the assembly port to facilitate the sliding of the electrode pieces 7 into the slots 14.

[0036] In a preferred embodiment, the flow-through electrolysis water structure of this embodiment further includes an end cap 5. The outer shell 1 has an assembly port 18 at one end near the water outlet 3, which communicates with the electrolysis chamber 15. The end cap 5 is closed and installed at the assembly port 18. Preferably, the end cap 5 and the outer shell 1 are connected by welding.

[0037] The outer casing of this embodiment is an integral structure, with both the water inlet channel 12 and the electrolysis chamber located within the casing. This integrated design results in a more compact and reliable structure. The flow-through electrolysis water structure of this embodiment has fewer structural components, a simpler assembly process, and lower costs; it also boasts better structural strength and higher pressure resistance, withstanding a 10kg water pressure test without cracking; the sealing surface is smaller, simplifying the welding process; and the welded surface provides higher strength and a simpler, more reliable seal.

[0038] As a preferred embodiment, such as Figure 4 and Figure 6As shown, multiple limiting blocks 52 are provided on the side of the end cap 5 near the electrolysis chamber 15, and the multiple limiting blocks 52 are arranged along the first direction x. Each limiting block 52 has two limiting grooves 521 adapted to the electrode plates 7, and the ends of the two electrode plates 7 near the end cap 5 are respectively engaged in the limiting grooves 521 of the multiple limiting blocks 52. The multiple limiting blocks 52 limit the ends of the two electrode plates 7 near the end cap 5, making the installation of the two electrode plates within the outer casing more stable. Preferably, the multiple limiting blocks 52 and the end cap 5 are an integral structure.

[0039] As a preferred embodiment, such as Figure 4 and Figure 7 As shown, the pins 71 of the two electrode plates 7 extend through the end cover 5 to its outer side, and the two electrode plates 7 are respectively connected to a wire harness 6 on the outer side of the housing 1.

[0041] As a preferred embodiment, such as Figure 7 As shown, a sealing groove 53 is provided on the side of the end cap 5 facing away from the electrolysis chamber 15. The leads 71 ​​of the two electrode plates 7 are respectively connected to the wire harness 6 through the sealing groove 53. A first potting compound 8 is poured into the sealing groove 53. The first potting compound 8 can seal the connection between the leads 71 ​​of the electrode plates 7 and the wire harness 6 to prevent water leakage.

[0042] A sealing groove 111 is formed between the periphery of the end cap 5 and the mounting nozzle 11, and a second potting compound 9 is poured into the sealing groove 111. Preferably, the first potting compound 8 is a soft glue; the second potting compound 9 is a hard glue.

[0043] As a preferred embodiment, such as Figure 5 As shown, the outlet 3 is located on the side of one electrode plate 7 away from the other electrode plate 7, and the water flow direction of both the inlet 2 and the outlet 3 is along the first direction x. The outlet 3 is located on the side opposite to the electrolytic plates, enabling the collection of the effluent after electrolysis. Preferably, both the inlet 2 and the outlet 3 are connected to the second side 17 of the outer casing. Two connecting legs 4 are provided on the side of the outer casing 1 opposite to the outlet 3, and the connecting legs 4 are used for connection to external components.

[0044] The flow-through electrolysis water structure of this embodiment can be applied to floor scrubbers, robot vacuum cleaners, smart toilets, dishwashers, sinks, faucets, etc., to electrolyze and produce electrolyzed water with a bactericidal effect.

[0045] The flow-through electrolysis water structure in this embodiment adopts a parallel water channel design, which allows the incoming water to flow evenly between the electrode plates, resulting in more complete electrolysis of tap water and a higher concentration of disinfectant water after electrolysis. Compared with the electrolysis efficiency of conventional single-channel modules, the concentration is about 20% higher. The water inlet channel and the electrolysis chamber are designed as a single unit, making the structure more compact and reliable.
