[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1As shown, its structure includes an electrolysis device of an embodiment of the utility model, specifically, including an electrolysis unit 100, the electrolysis unit 100 includes a shell 110 and a stack 300, the shell 110 is formed with a water inlet 101, a receiving cavity 107 and a water outlet 102, the stack 300 is arranged in the receiving cavity 107, and the stack 300 includes a first electrode 310 and a second electrode 320 arranged in sequence. The shell 110 is formed with an assembly groove 103 on one side of the receiving cavity 107, the assembly groove 103 is connected to the receiving cavity 107, the water inlet 101 is connected to the receiving cavity 107 and / or the assembly groove 103, and the receiving cavity 107 and / or the assembly groove 103 are connected to the water outlet 102.

[0023] It should be understood that the housing 110 is formed with a water inlet 101 and a water outlet 102, for example, the water inlet 101 is in communication with the accommodating chamber 107, or the water inlet 101 is in communication with the assembly groove 103, so that the external water enters the accommodating chamber 107 through the water inlet 101 and is electrolyzed by the stack 300 (the first electrode 310 and the second electrode 320). The first electrode 310 and the second electrode 320 are electrically connected to a power supply / voltage to achieve electrolysis and oxidation reduction of water molecules to produce electrolyzed water.

[0024] The beneficial effects of the present invention are:

[0025] The side of the shell 110 is provided with an assembly groove 103 connected to the accommodating chamber 107, and the water inlet 101 is connected to the assembly groove 103 or the accommodating chamber 107. The assembly groove 103 and the accommodating chamber 107 can be installed with a cover plate 200 according to actual conditions to control the formation of the required water flow channel. For example, when the required electrolyzed water concentration is low, the cover plate 200 can be installed in the assembly groove 103, and the water enters the assembly groove 103 from the water inlet 101. The water path enters in a direction perpendicular to the stack 300. The water quickly passes through the electrolysis unit 100 and is electrolyzed and converted into electrolyzed water. When the required electrolyzed water concentration is high, a water flow channel parallel to the stack 300 is formed through the assembly groove 103, so that the water stays in the electrolysis unit 100 for a longer time and is electrolyzed and converted into electrolyzed water with a higher concentration.

[0026] Through the above structure, the flow direction and flow channel of the water body in the electrolysis unit 100 can be conveniently controlled, so that the electrolysis is more complete. The flow channel can be replaced according to the water flow rate and the required concentration, and the concentration of electrolyzed water can be adjusted, so that the electrolysis device can adapt to the electrolysis of water bodies with multiple flow rates and concentrations and provide an adaptive electrolysis efficiency. The required flow channel can be formed by superimposing a single module, and replacement and disassembly are more convenient, which reduces the production cost.

[0027] In one embodiment, the assembly groove 103 is detachably mounted with a cover plate 200. Further, in one embodiment, the accommodating chamber 107 is detachably mounted with a water inlet end plate 120. By installing the cover plate 200 in the assembly groove 103 or installing the water inlet end plate 120 on the accommodating chamber 107, the water flow channel can be conveniently regulated. In one embodiment, the water inlet end plate 120 is provided with a water through hole 121. Water can enter the accommodating chamber 107 through the water through hole 121.

[0028] In one embodiment, there are multiple electrolysis units 100, and each of the electrolysis units 100 is stacked in sequence. By stacking multiple electrolysis units 100, the concentration of electrolyzed water can be increased.

[0029] In one embodiment, the assembly slots 103 between two adjacent electrolytic units 100 are staggered. By stacking a plurality of electrolytic units 100 and staggering the assembly slots 103, the electrolytic unit 100 structure with a uniform mold can be formed into a tortuous, reciprocating flow channel, as shown in 1, which can be appropriately stacked according to the number of electrolytic units 100 required. In this embodiment, the stacked electrode units are all the same, but can form a complex, multi-style water flow channel, and only the installation position needs to be adjusted during assembly, so that the flow channel is more diversified without complicating the overall structure, and the production cost is lower.

[0030] In one embodiment, the assembly grooves 103 between two adjacent electrolytic units 100 are respectively provided on both sides of the housing 110. In one embodiment, two assembly grooves 103 are provided on the housing 110 of one electrolytic unit 100, and the two assembly grooves 103 are respectively provided on both sides of the housing 110. In this embodiment, by providing assembly grooves 103 on both sides of the housing 110 (i.e., on both sides of the accommodating cavity 107), a complex water flow channel with various styles can be formed. It is only necessary to adjust the installation position during assembly and to appropriately install the cover plate 200 in the assembly groove 103 to make the flow channel more diversified without complicating the overall structure, and the production cost is lower.

[0031] In the present application, the stack 300 includes a first electrode 310 and a second electrode 320 stacked in sequence, and the first electrode 310 and the second electrode 320 are arranged relatively parallel. For example, a water gap 109 is formed between the stack 300 and the side wall of the accommodating cavity 107 for water to flow. For another example, a plate space for water to flow through is formed between the first electrode 310 and the second electrode 320. For another example, the stack 300 is provided with a through hole 309 that runs through each layer of the stack 300, that is, the first electrode 310 and the second electrode 320 are provided with a through hole 309 for water to flow through. The first electrode 310 and the second electrode 320 are externally connected to a power supply voltage, and the water flowing through the stack 300 is electrolyzed by the first electrode 310 and the second electrode 320 to produce electrolyzed water.

[0032] For example, the electrolyzed water contains oxidizing groups such as oxygen atoms, ozone, and hydroxyl radicals. The oxidizing groups have strong oxidizing properties and have a strong oxidizing bactericidal effect. The generated electrolyzed water / electrolyzed water mist can sterilize and disinfect external objects or the environment.

[0033] In one embodiment, the stack 300 further includes a solid electrolyte membrane, which is disposed between the first electrode 310 and the second electrode 320. The proton exchange membrane (PEM) is used to provide a hydrogen ion channel, i.e., the H generated at the anode. + Migrate to the cathode through the proton exchange membrane, thereby increasing the reaction rate and the product formation rate.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
