[0041] Refer to the following Figures 1 to 7 The electrolytic water module, liquid containing device and floor scrubber provided by the utility model are described.

[0042] The floor scrubber includes a machine body, a brush plate and a liquid holding device. The brush plate is rotatably connected to the machine body, and the brush plate is driven to rotate by a motor. The specific connection structure between the machine body and the brush plate is in the prior art and will not be described in detail here. The liquid holding device is connected to the machine body, and a high-pressure water pump is built into the machine body.

The liquid holding container 8 includes an upper portion 81 and a lower portion 82 which are sealed and connected. The electrolytic water module is placed inside the lower portion 82 and connected to the side wall of the lower portion 82. The liquid holding device can be applied to any cleaning appliance such as a floor scrubber, a smart toilet, a fruit and vegetable washing machine, etc. The electrolytic water module electrolyzes water to generate acidic ion water that can kill bacteria, and the acidic ion water is used for sterilization and disinfection.

[0044] Reference Figure 2 The water electrolysis module includes a module body 1, an electrode sheet 2, a connecting column 3, a conductive connecting member 4 and a fixed connecting member 5. The module body 1 is hollow, the electrode sheet 2 is arranged inside the module body 1, the connecting column 3 is connected to the outside of the module body 1, the connecting column 3 is hollow, the conductive connecting member 4 passes through the connecting column 3, the two ends of the conductive connecting member 4 are respectively connected to the electrode sheet 2 and the external power supply, and the fixed connecting member 5 is connected to the connecting column 3.

[0045] Specifically, the module body 1 includes a box body 11 and a cover body 12. One side of the box body 11 has an opening. In this embodiment, the opening of the box body 11 is located at the top of the box body 11. The cover body 12 covers the opening of the box body 11. A plurality of through holes 121 are provided on the box body 11 and / or the cover body 12. The through holes 121 in this embodiment are provided on the cover body 12. The through holes 121 enable liquid to flow into or out of the module body 1, thereby realizing the circulation of liquid.

[0046] The connecting column 3 is connected to the side wall of the box body 11, and the connecting column 3 connects the inside of the module body 1 with the outside of the module body 1. A partition 114 is arranged inside the box body 11, and the partition 114 is arranged perpendicular to the axis of the connecting column 3. A gap is left between the partition 114 and the side wall of the box body 11 close to the connecting column 3.

[0047] Furthermore, the electrode sheet 2 is arranged parallel to the cover body 12, and the electrode sheet 2 is located on the side of the partition 114 away from the connecting column 3. A conductive sheet 21 is connected to the electrode sheet 2, and the conductive sheet 21 is arranged perpendicular to the electrode sheet 2, that is, the conductive sheet 21 is perpendicular to the axis of the connecting column 3, and the conductive sheet 21 is located on the side of the partition 114 close to the connecting column 3.

[0048] Reference Figure 3 , the conductive sheet 21 seals and blocks the end of the connection column 3 connected to the inside of the module body 1. Specifically, a U-shaped boss 113 is provided on the side wall of the box body 11 near the connection column 3, and the opening of the boss 113 faces upward. The conductive sheet 21 abuts against the boss 113, so that a sealing groove 111 is formed between the conductive sheet 21 and the inner wall of the box body 11, and one end of the connection column 3 is connected to the sealing groove 111. A first sealing ring 61 is provided inside the sealing groove 111. The first sealing ring 61 is coaxially arranged with the connection column 3. The first sealing ring 61 abuts between the inner wall of the box body 11 and the conductive sheet 21. The inside of the sealing groove 111 is filled with sealant, and the sealant fills the outer ring of the first sealing ring 61. The sealant is preferably waterproof glue.

[0049] Based on the above, the gap between the conductive sheet 21 and the box body 11 is sealed by the sealant to form a first waterproof layer. The first sealing ring 61 is made of elastic materials such as rubber or resin plastic. The first sealing ring 61 abutted between the inner wall of the box body 11 and the conductive sheet 21 fills the gap between the inner wall of the box body 11 and the conductive sheet 21 through its own elasticity, thereby forming a second waterproof layer through the first sealing ring 61, thereby achieving a good waterproof effect and preventing liquid from entering the interior of the connecting column 3. Secondly, the first sealing ring 61 can also prevent the sealant from entering the interior of the connecting column 3 when filling the sealant, causing the glue to adhere to the conductive connector 4.

[0050] Reference Figure 4 and Figure 5 Optionally, the fixed connector 5 can be independently provided, and the fixed connector 5 is passed through and sealedly connected to the inner wall of the lower portion 82, or it can be integrally provided with the lower portion 82, that is, it is a part of the lower portion 82. In this embodiment, the independently provided fixed connector 5 is used as an example. Specifically, a mounting hole 821 is provided on the lower portion 82, and the fixed connector 5 is plugged into and matched with the mounting hole 821, and the fixed connector 5 is flush with the outer wall of the lower portion 82, thereby improving the overall aesthetics.

[0051] An annular glue pouring groove 822 is provided on the inner wall of the lower portion 82 along the circumference of the mounting hole 821, and a sealing ring 52 is connected to the fixed connector 5. The sealing ring 52 is plugged into and matched with the glue pouring groove 822, and the glue pouring groove 822 is filled with sealant, thereby achieving sealing at the connection between the fixed connector 5 and the lower portion 82 and preventing the liquid inside the lower portion 82 from flowing out from the connection between the fixed connector 5 and the lower portion 82.

[0052] Reference Figure 6 and Figure 7 , further, a sealing through hole 51 is provided on the fixed connector 5, and the connecting column 3 can be plugged into and matched with the sealing through hole 51, and sealed with the inner wall of the sealing through hole 51. Specifically, a limiting ring groove 31 is provided on the outer wall of the connecting column 3, and a plurality of limiting ring grooves 31 are provided along the axial direction of the connecting column 3. In this embodiment, two are taken as an example. A second sealing ring 62 is sleeved on the outer wall of the connecting column 3, and a portion of the second sealing ring 62 is placed inside the limiting ring groove 31, and the inner ring of the second sealing ring 62 abuts against the side wall of the limiting ring groove 31, and the outer ring of the second sealing ring 62 abuts against the inner wall of the sealing through hole 51. The material and effect of the second sealing ring 62 refer to the first sealing ring 61, and will not be repeated here, so as to achieve a sealing match between the fixed connector 5 and the connecting column 3, and prevent the liquid outside the fixed connector 5 from entering the inside of the sealing through hole 51, so that the inside of the sealing through hole 51 is well sealed.

[0053] It should be noted that a single anode electrode sheet 2 can produce acidified water, and a single cathode electrode sheet 2 can produce alkaline electrolyzed water. If a single anode electrode sheet 2 is used in combination with a single cathode electrode sheet 2, slightly acidic electrolyzed water can be produced. In this embodiment, two electrode sheets 2 are arranged in parallel, one of which is an anode electrode sheet 2 and the other is a cathode electrode sheet 2. The two electrode sheets 2 are separated by a separator 22 so that there is a gap between the two electrode sheets 2. The above-mentioned sealing groove 111, connecting column 3, conductive connector 4 and sealing through hole 51 are arranged one for each electrode sheet 2.

[0054] Specifically, the conductive connector 4 includes a conductive spring 41 and a conductive cap 42. The conductive spring 41 is located inside the connecting column 3. One end of the conductive spring 41 is connected to the conductive sheet 21, and the other end of the conductive spring 41 is connected to the conductive cap 42. The conductive cap 42 is arranged in a hollow cylindrical shape, one end of the conductive cap 42 is arranged in a closed manner, the conductive cap 42 is slidably matched with the sealing through hole 51, the conductive cap 42 slides axially along the sealing through hole 51, and one end of the conductive cap 42 is exposed from the sealing through hole 51. The conductive spring 41 is used to apply elastic force to the conductive cap 42. When the conductive cap 42 abuts against the external power supply, it can ensure that the conductive cap 42 is effectively in contact with the external power supply.

[0055] It is worth noting that, in other embodiments, a conductive metal rod may also be used as the conductive connecting member 4, and the specific form is not limited.

[0056] Furthermore, the sealing through hole 51 is a stepped hole, and the diameter of the sealing through hole 51 at one end close to the box body 11 is larger than the diameter at the end away from the box body 11. The other end of the conductive cap 42 is coaxially connected to the limiting ring 421. When the conductive spring 41 drives the limiting ring 421 to abut against the step inside the sealing through hole 51 through its own elastic force, a limiting structure is formed by the step of the stepped hole and the limiting ring 421 to prevent the conductive cap 42 from being separated from the sealing through hole 51.

[0057] Reference Figure 2 In addition, a mounting groove 112 is provided inside the module body 1, and a printed circuit board 7, i.e., a PCB board, is provided inside the mounting groove 112. The inside of the mounting groove 112 is filled with sealant, so that the sealant fully covers the printed circuit board 7, thereby sealing the printed circuit board 7 and reducing the contact with the liquid inside the box body 11. The printed circuit board 7 is electrically connected to the electrode sheet 2, and an indicator light 71 is provided on the printed circuit board 7. The indicator light 71 is exposed outside the cover body 12, and a lampshade (not shown in the figure) is provided outside the indicator light 71. The working state of the electrode sheet 2 is monitored by the electronic components on the printed circuit board 7, and the indicator light 71 is controlled to change color or adjust the flashing frequency, thereby displaying the working state of the water electrolysis module.
