[0028] In the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] Please refer toFigures 1 to 6 , an embodiment of the present utility model provides an over-flow type electrolyzed water module, which includes a main housing 1 and an electrolysis sheet assembly 2 disposed in the main housing 1; the housing has a closed internal cavity 11, and at least one water inlet 121 communicating with the internal cavity 11 and at least one water outlet 122 communicating with the internal cavity 11 are formed on the main housing 1; a connection relief groove 131 for the electrolysis sheet assembly 2 to pass through is formed on the main housing 1.

[0030] The external solution enters the internal cavity 11 from the water inlet 121 and is electrolyzed by the electrolysis sheet assembly 2, so as to form sterilized water in the internal cavity 11, and the electrolyzed sterilized water flows out through the water outlet 122. The sterilized water generated after the solution is electrolyzed can, on the one hand, disinfect the environment in the internal cavity 11 to prevent the growth of microorganisms such as molds inside, improving the safety of this module. On the other hand, after flowing out from the water outlet 122, it is used for cleaning external household appliances such as floor washers, improving the practicability of this module, avoiding the trouble of adding different cleaning agents, fungicides, and the purchase, addition, and storage by users, and improving people's usage experience. By forming a connection relief groove 131 on the main housing 1 for the electrolysis sheet assembly 2 to pass through, the electrolysis sheet is electrically connected to the circuit board of an external household appliance such as a floor washer through the connection relief groove 131, so as to implement the commands of the external circuit board to start and close the electrolysis sheet assembly 2. The overall structure of this module is simple and convenient to use, which is beneficial to production and use. Preferably, the solution is water.

[0031] A waterproof soft glue can also be provided on the connection relief groove 131 to isolate the water source and ensure the electrical connection between the electrolysis sheet assembly 2 and the external circuit.

[0032] Regarding the specific structural settings of the electrolysis sheet assembly 2, such as Figure 4 and Figure 5As shown in the figure, the electrolytic sheet assembly 2 includes at least one first electrolytic sheet 21 disposed in the internal cavity 11, at least one second electrolytic sheet 22 disposed in the internal cavity 11 and parallel to the first electrolytic sheet 21, at least one first connection wire 23 with one end connected to the first electrolytic sheet 21 and the other end passing through the connection relief groove 131 to be electrically connected to an external circuit, and at least one second connection wire 24 with one end connected to the second electrolytic sheet 22 and the other end passing through the connection relief groove 131 to be electrically connected to an external circuit. The first electrolytic sheet 21 and the second electrolytic sheet 22 are stacked. The first electrolytic sheet 21 is connected to the positive electrode of an external household appliance through the first connection wire 23, and the second electrolytic sheet 22 is connected to the negative electrode of the external household appliance through the second connection wire 24, thereby forming a complete anode and cathode in the internal cavity 11. Furthermore, an electrolysis reaction can occur in the solution in the internal cavity 11, thus forming sterilized water. Regarding whether the first electrolytic sheet 21 is located above the second electrolytic sheet 22 or the second electrolytic sheet 22 is located above the first electrolytic sheet 21, it can be set according to actual circumstances, so no specific limitation is made in this embodiment. The number of the first electrolytic sheet 21 and the second electrolytic sheet 22 can also be selected according to actual circumstances, as long as they correspond one by one. The principle of the first electrolytic sheet 21 and the second electrolytic sheet 22 electrolyzing the solution to form sterilized water is prior art, so no specific elaboration is made in this embodiment.

[0033] Regarding the specific structural setting of the housing, such as Figures 1 to 6 As shown in the figure, the main housing 1 includes a lower housing 12 and an upper housing 13 hermetically connected to the lower housing 12. The internal cavity 11 is disposed between the lower housing 12 and the upper housing 13. The connection relief groove 131 is formed on one side of the upper part of the upper housing 13, and the water inlet 121 and the water outlet 122 are formed on the side of the lower housing 12.

[0034] To prevent the first connection wire 23 and the second connection wire 24 from shifting during operation, as shown in Figures 1 to 2 and Figures 4 to 6 As shown in the figure, at least one connection wire hook 132 with an overall L-shaped configuration is further formed on the outer side of the upper housing 13 close to the first connection wire 23 and the second connection wire 24. The first connection wire 23 and the second connection wire 24 are received in the connection wire hook 132, thereby effectively preventing the first connection wire 23 and the second connection wire 24 from shifting during operation and ensuring the electrolysis efficiency of this module. The number of the connection wire hooks 132 can be correspondingly set according to the number of the first connection wire 23 and the second connection wire 24, so no specific limitation is made in this embodiment.

[0035] To prevent the problem of uneven electrolysis caused by the displacement of the electrolytic sheet assembly 2 during operation, as shown inFigure 2 As shown, on the side edges of the lower end face of the upper housing 13, at least one upper housing side pressing block 133 that presses against the side edges of the upper end face of the first electrolytic sheet 21 and is overall cross-shaped is symmetrically formed. In the middle of the lower end face of the upper housing 13, an upper housing middle pressing block 134 that presses against the middle of the upper end face of the first electrolytic sheet 21 and is overall cross-shaped is formed. The upper housing side pressing block 133 presses against the side edges of the upper end face of the first electrolytic sheet 21, and the upper housing middle pressing block 134 presses against the middle of the upper end face of the first electrolytic sheet 21. The two cooperate to fix the first electrolytic sheet by the upper housing 13, preventing the problem that the first electrolytic sheet 21 shifts during operation, resulting in uneven electrolysis. By setting the upper housing side pressing block 133 and the upper housing middle pressing block 134 to a cross-shaped structure, the cross-shaped structure can press against all four angles, so that the first electrolytic sheet 21 is fixed more firmly, further preventing displacement and ensuring the normal operation of this module.

[0036] To further prevent the problem that the electrolytic sheet assembly 2 shifts during operation, resulting in uneven electrolysis, as Figure 3 shown, on the side edges of the upper end face of the lower housing 12, at least one lower housing side pressing block 123 that presses against the side edges of the lower end face of the second electrolytic sheet 22 is symmetrically formed. In the middle of the lower end face of the lower housing 12, a lower housing middle pressing block 124 that presses against the middle of the lower end face of the second electrolytic sheet 22 and is overall cross-shaped is formed. The lower housing side pressing block 123 presses against the side edges of the lower end face of the second electrolytic sheet 22, and the lower housing middle pressing block 124 presses against the middle of the lower end face of the second electrolytic sheet 22. The two cooperate to fix the second electrolytic sheet 22 by the upper housing 13, preventing the problem that the second electrolytic sheet 22 shifts during operation, resulting in uneven electrolysis. By setting the lower housing middle pressing block 124 to a cross-shaped structure, the cross-shaped structure can press against all four angles, so that the middle of the second electrolytic sheet 22 is fixed more firmly, further preventing displacement and ensuring the normal operation of this module.

[0037] To prevent a short circuit between the first electrolytic sheet 21 and the second electrolytic sheet 22, as Figure 4 and Figure 5As shown, the electrolytic sheet assembly 2 also includes at least one insulating sheet 25 disposed between the first electrolytic sheet 21 and the second electrolytic sheet 22, and at least one water hole is formed on the insulating sheet 25. By disposing the insulating sheet 25 between the first electrolytic sheet 21 and the second electrolytic sheet, the first electrolytic sheet 21 and the second electrolytic sheet 22 are separated to avoid direct conduction between the first electrolytic sheet 21 and the second electrolytic sheet 22, resulting in a short circuit, thereby affecting the electrolysis reaction of the solution in the internal cavity 11. By disposing at least one water hole on the insulating sheet 25, the water holes are arranged in sequence at intervals, thereby effectively ensuring the smooth flow of the solution between the first electrolytic sheet 21 and the second electrolytic sheet 22, so that the electrolyzed sterilizing water can smoothly flow out from the water outlet 122, ensuring the normal operation of this module.

[0038] For the specific structural setting of the water hole, Figure 4 and Figure 5 As shown, the water holes include a circular water hole 251 formed in the middle of the insulating sheet 25, and four groups of polygonal water holes 252 surrounding the side of the circular water hole 251 and giving way to the circular water hole 251. The circular water hole 251 is used to give way to the solution flowing through the middle of the first electrolytic sheet 21 and the middle of the second electrolytic sheet 22. By arranging four groups of polygonal water holes 252 surrounding the side of the circular water hole 251 around the circular water hole 251, the solution can pass through all parts of the insulating sheet 25. The polygonal water holes 252 are used to give way to the solution flowing through the side of the first electrolytic sheet 21 and the side of the second electrolytic sheet 22. The two cooperate with each other so that the solution can be fully electrolyzed by the first electrolytic sheet 21 and the second electrolytic sheet 22 to form sterilizing water when flowing through the first electrolytic sheet 21 and the second electrolytic sheet 22, thereby preventing the solution from accumulating on the insulating sheet 25, resulting in the problem of failure of normal electrolysis, and ensuring the normal operation of this module.

[0039] The specific method of connecting the first electrolyte sheet 21 to the first connecting line 23 and the second electrolyte sheet 22 to the second connecting line 24 is as follows: Figure 4As shown, a first connection piece 211 protruding outward is formed on one side of the first electrolytic sheet 21. The first connection wire 23 is connected to the first connection piece 211, so that the first electrolytic sheet 21 is connected to the first connection wire 23 through the first connection piece 211 and is electrically connected to an external circuit, receiving start and stop signals from the external circuit and receiving power supply from an external power source. A second connection piece 221 protruding outward and offset from the first connection piece 211 is formed on one side of the second electrolytic sheet 22. The second connection wire 24 is connected to the second connection piece 221, so that the second electrolytic sheet 22 is connected to the second connection wire 24 through the second connection piece 221 and is electrically connected to an external circuit, receiving start and stop signals from the external circuit and receiving power supply from an external power source.

[0040] To prevent the problem that the first connection wire 23 and the second connection wire 24 come into contact with water source and cause short circuit, as Figures 2 to 6 shown, a first upper shell barrier piece 135 extending downward is formed on the lower end surface of one end of the upper shell 13 close to the first connection wire 23 and the second connection wire 24. A first upper shell through hole 136 for the first connection piece 211 to pass through and a second upper shell through hole 137 for the second connection piece 221 to pass through are formed in the lower part of the first upper shell barrier piece 135. A lower shell placement table 125 for placing the first connection piece 211 and the second connection piece 221 is formed on the upper end surface of one end of the lower shell 12 close to the first connection wire 23 and the second connection wire 24. Placement table pressing pieces 126 for pressing against the side wall of the connection relief groove 131 are formed on both sides of the upper end of the lower shell placement table 125. A placement table spacer 127 for spacing the first connection piece 211 and the second connection piece 221 is formed in the middle of the lower shell placement table 125.

[0041] The first connecting piece 211 passes through between the through hole 136 of the first upper shell and the lower shell placement table 125, so as to realize the stable installation of the first connecting piece 211. The second connecting piece 221 passes through between the through hole 137 of the second upper shell and the lower shell placement table 125, so as to realize the stable installation of the second connecting piece 221. And the upper shell barrier piece 135 presses against the lower shell placement table 125, so that the connection relief groove 131 and the waterproof soft glue cooperate to form another sealed cavity isolated and independent from the internal cavity 11, preventing the solution flowing in the internal cavity 11 from entering the connection relief groove 131 and causing the first connecting wire 23 and the second connecting wire 24 to contact the water source and lead to a short circuit. One end of the first connecting wire 23 is connected to the first connecting piece 211 in the connection relief groove 131, and the other end passes through the waterproof soft glue and is connected to an external circuit, so as to prevent the problem that the first connecting wire 23 contacts the water source and causes a short circuit. One end of the second connecting wire 24 is connected to the second connecting piece 221 in the connection relief groove 131, and the other end passes through the waterproof soft glue and is connected to an external circuit, so as to prevent the problem that the second connecting wire 24 contacts the water source and causes a short circuit. By forming a placement table spacer 127 in the middle of the lower shell placement table 125 to separate the first connecting piece 211 and the second connecting piece 221, the first connecting piece 211 and the second connecting piece 221 on the connection relief groove 131 are isolated, preventing the problem that the first connecting wire 23 and the second connecting wire 24 are directly conducted and cause a short circuit, and ensuring the normal operation of this module. By forming a placement table pressing piece 126 on both sides of the upper end of the lower shell placement table 125 to press against the side wall of the connection relief groove 131, the side wall of the connection relief groove 131 is tightly connected to the lower shell placement table 125, preventing the solution from leaking out.

[0042] Preferably, as Figure 4 shown, several water passing holes arranged uniformly may also be provided on the first connecting piece 211, so as to facilitate the solution to complete electrolysis from the first electrolytic piece 21 to the second electrolytic piece 22.

[0043] Preferably, as Figures 4 to 6 shown, both the first connecting piece 211 and the second connecting piece 221 are fixed to the connection relief groove 131 by screws.

[0044] Preferably, as Figures 1 to 6 shown, in order to facilitate the installation of this module, an installation table 128 is symmetrically arranged on the side edge of the lower shell 12. The module can be fixed to a specific position for work by aligning and passing through the installation table 128 with screws, improving the practicability of this module.

[0045] It should be noted here that the flow-through electrolyzed water module disclosed by the present utility model is an improvement on the specific structure, and the specific control method is not the innovation point of the present utility model.
