Description

[0001] This application is a divisional application of Chinese Patent Application No. 202410026472.8, entitled "A Flat Electrolysis Device and Floor Scrubber", filed on January 8, 2024, the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of cleaning equipment technology, and in particular to a flat electrolysis device and a floor scrubber. Background Technology

[0003] With the advancement of technology, people's requirements for floor cleaning tools have gradually increased. The first to emerge was the vacuum cleaner, which relies on electricity and generates negative pressure to suck up trash and dust from the floor. Classified by cleaning methods and the flow path of small and large particles of debris, this type of technology is usually categorized as air-dust circulation technology. However, due to the limitations of its working principle, vacuum cleaners cannot clean some stubborn trash and stains adhering to the floor. Therefore, a new type of floor scrubber, the "water-dust circulation" model, has emerged. This scrubber uses a motor to drive a cleaning drum to wipe the floor, and is also equipped with a water supply system and a water tank to clean the cleaning drum, thus achieving floor cleaning.

[0004] Currently, more and more floor scrubbers are integrating electrolysis modules into their water tanks or bodies. These modules electrolyze the cleaning water into electrolyzed water containing bactericidal components, which is then output to the cleaning rollers on the cleaning head to clean the floor. Summary of the Invention

[0005] This application provides a flat electrolysis device and a floor scrubber, which aims to reduce the size of the electrolysis device inside the floor scrubber, reduce the overall weight of the floor scrubber, improve the efficiency of the electrolysis device in electrolyzing cleaning water, and simplify and shorten the connection of the water supply pipeline between the electrolysis device and the water tank and the surface of the cleaning roller.

[0037] Secondly, this application discloses a floor scrubbing machine, including a water tank, a cleaning head, and a flat electrolysis device as described in the first aspect, disposed at the end of the water tank.

[0038] Based on the above technical solution, the beneficial effects of the present invention compared with the prior art are as follows:

[0039] In the electrolysis device of this application, the electrolysis module is disposed in a hollow shell with a cavity. In actual installation, the electrolysis device can be placed on the cleaning head shell corresponding to the end of the water tank. The electrolysis device is connected to the water outlet of the water tank and the water supply pipe that delivers clean water to the cleaning roller of the cleaning head. Since at least part of the electrolysis module is lower than the height of the water inlet of the electrolysis device, the clean water enters the cavity of the electrolysis device from the water inlet under the action of gravity and undergoes sufficient electrolysis in at least part of the electrolysis module. Moreover, since the height of the water outlet of the electrolysis device is not lower than the lowest point of the electrolysis module, the clean water to be electrolyzed will not flow out of the water outlet immediately after entering the cavity. The clean water to be electrolyzed flows into the cavity from the water inlet, flows along the periphery of the cavity in a semi-circular path through the electrolysis module, and then flows out of the water outlet. This is conducive to the clean water being fully electrolyzed in the cavity. This electrolysis device has a simple and compact structure. It can electrolyze clean water and deliver sterilized cleaning water to the surface of the cleaning roller without the need for other structures. The overall size of the electrolysis device is small, which can greatly reduce the overall weight of the floor scrubber, making the floor scrubber using this electrolysis device lighter and easier to use.

[0040] The electrolysis device of this application adopts a flat structure and is installed on the side wall of the cleaning head housing corresponding to the end of the water tank. The area of ​​the electrolysis device projected onto the end of the water tank is smaller than the area of ​​the end of the water tank itself, occupying only a small space of the housing side wall thickness. The pipe interface of the water inlet of the electrolysis device is not on the same plane and is perpendicular to each other, which facilitates the water inlet pipe interface to connect to the water tank with the shortest connection pipe path. At the same time, the pipe interface of the water outlet extends from the peripheral wall of the electrolysis device housing along the side of the cleaning head 1 housing parallel to the end face of the water tank to the cleaning roller and connects to the surface of the cleaning roller with the shortest connection pipe path. The electrolysis device as a whole and the matching connection pipe occupy a small volume, which can greatly reduce the overall weight of the floor scrubber, thereby making the floor scrubber using this electrolysis device lighter and more portable, and also simplifying and shortening the connection of the water supply pipe between the electrolysis device and the water tank and the surface of the cleaning roller.

[0041] The electrolysis device in this application is set up independently of the clear water chamber of the water tank. Each electrolysis only electrolyzes the liquid entering the chamber, without needing to electrolyze the liquid in the entire clear water chamber. The electrolysis space is small, which can improve the electrolysis efficiency and shorten the electrolysis time. The concentration of electrolyzed water containing bactericidal components produced per unit time is higher than that of the prior art.

[0042] The electrolysis device in this application is closely attached to the end of the water tank and is installed at the same level as the lowest point of the clean water chamber. The height difference between the two is small. When the water tank is installed horizontally on the cleaning head, compared with the conventional method of setting the electrolysis device on the machine body and conveying clean water from the water tank on the cleaning head to the electrolysis device during use, the electrolysis device in this application does not need to overcome a large potential energy difference to convey the clean water in the clean water chamber to the electrolysis device for electrolysis. This can reduce energy consumption and shorten the path for conveying the electrolyzed, sterilizing clean water to the surface of the cleaning roller. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0068] The present invention will be further described below with reference to specific embodiments, but these are not intended to limit the scope of the invention.

[0069] The applicant discovered that in some existing floor scrubbers, the electrolysis device is integrated into the water tank. For example, the applicant's Chinese patent, CN116982887A, discloses a cleaning device with a water electrolysis module at the bottom of the clean water chamber. The water tank is equipped with an adapter box located away from the clean water outlet for powering the water electrolysis module, preventing short circuits between the electrodes caused by water leakage. Simultaneously, the sealed bottom cover structure of the clean water tank, combined with the power adapter box, ensures complete insulation between the water tank and the water electrolysis module's electrodes, while also guaranteeing a degree of maintainability for the water electrolysis module's connection. This facilitates production and allows consumers to easily replace the water electrolysis module themselves.

[0070] The applicant also discovered that in some other floor scrubbers, the electrolysis device is integrated into the machine body, such as the applicant's Chinese patent with authorization publication number CN220089382U, which discloses a machine body shell, a floor scrubber body, and a floor scrubber. The machine body shell includes a main shell, a bottom shell, and a top cover. The floor scrubber body includes a water electrolysis device and a water pump. The main shell includes a first mounting surface and a second mounting surface arranged opposite each other. The first mounting surface has a water electrolysis device mounting section for mounting the water electrolysis device. The second mounting surface has a water pump receiving chamber for accommodating the water pump. The main shell has a through hole, and the water electrolysis device includes an electrolysis tank, such that at least part of the electrolysis tank passes through the through hole. The bottom shell and the top cover are respectively mounted on the first and second mounting surfaces.

[0071] In summary, the applicant concludes that the electrolysis devices in existing "water-dust circulation" floor scrubbers, whether located at the bottom of the water tank or on the machine body, inevitably occupy a large volume, which easily increases the overall weight of the floor scrubber and makes it inconvenient to use. At the same time, the electrolysis devices in existing floor scrubbers often electrolyze the clean water in the entire water tank during operation, and the concentration of bactericidal components in the produced electrolyzed water is not high.

[0072] Therefore, in order to reduce the size of the electrolysis device inside the floor scrubber, reduce the overall weight of the floor scrubber, improve the efficiency of the electrolysis device in producing electrolyzed water with a high concentration of antibacterial components, and simplify and shorten the connection of the water supply pipeline between the electrolysis device and the water tank and the surface of the cleaning roller, the applicant further developed and made this invention.

[0073] In a first aspect, embodiments of this application provide an electrolysis apparatus 100, referring to... Figures 1 to 9 The electrolysis device 100 is flat and includes a housing 110 and an electrolysis module 120. The housing 110 is hollow to form a cavity 130. The electrolysis module 120 is disposed in the cavity 130. The housing 110 is provided with an inlet 140 that communicates with the cavity 130 and is connected to the water tank 10 of the floor scrubber. The housing 110 is provided with an outlet 150 that communicates with the cavity 130 and is connected to the surface of the cleaning roller (not shown in the figure) installed on the housing of the cleaning head 1 through a pipeline. At least a portion of the electrolysis module 120 is located below the inlet 140.

[0074] Specifically, such as Figure 7 , Figure 8 , Figure 9As shown, the electrolysis device 100 in this application can be installed on the housing of the cleaning head 1 at the end of the water tank 10. The water tank 10 includes a clean water tank 10a and a wastewater tank 10b, which are arranged vertically or horizontally, by a partition (not shown in the figure) inside the tank. Preferably, the clean water tank 10a is located at the upper part of the water tank 10, and the wastewater tank 10b is located at the lower part of the water tank 10. The interior of the clean water tank 10a is hollow, forming a clean water cavity that can hold clean water. The electrolysis device 100 connects the outlet (not shown in the figure) of the clean water tank 10a to the water supply pipe (not shown in the figure) that transports clean water to the cleaning roller of the cleaning head 1. The electrolysis device 100 in this application occupies a small volume, which can greatly reduce the overall weight of the floor scrubber, making the floor scrubber lighter and easier to use.

[0075] In addition, such as Figure 2 , Figure 3 As shown, the cavity 130 is independently housed within the casing 110. The casing 110 is connected to the clean water cavity and the cleaning roller of the cleaning head 1 via the inlet 140 and outlet 150, respectively. This allows the electrolysis device 100 to be set up independently of the clean water cavity. Each electrolysis operation only requires electrolysis of the liquid entering the cavity 130, rather than electrolyzing the entire liquid in the water tank. The smaller electrolysis space increases the concentration of effective bactericidal components in the electrolyzed water, thereby improving the bactericidal efficiency of the produced electrolyzed water.

[0076] In one or more alternative embodiments, such as Figure 7 , Figure 8 , Figure 9 As shown, the area of ​​the housing 110 projected onto the end plane of the water tank 10 is smaller than the area of ​​the end plane of the water tank 10 itself. This effectively utilizes the limited space between the end plane of the water tank 10 and the side wall of the cleaning head 1's housing, allowing the electrolysis device 100 to complete the electrolysis of the clean water drawn from the water tank 10 within this confined space, thereby increasing the concentration of effective bactericidal components in the electrolyzed water produced by the electrolysis device 100.

[0077] Of course, for easier connection of the inlet 140 and outlet 150 pipes, such as Figure 8 , Figure 9 As shown, the area of ​​the housing 110 projected onto the end plane of the water tank 10 can slightly exceed the area framed by the end plane of the water tank 10 itself. The excess part is just enough to reserve the water inlet 140 and / or the water outlet 150 for pipeline connection. This is more conducive to improving the utilization rate of the internal space of the cleaning head 1, making the floor scrubber lighter and easier to use.

[0078] In an optional embodiment, in the electrolysis device 100 of this application, both the inlet 140 and the outlet 150 are pipe interfaces connecting to the cavity 130; the pipe interfaces of the inlet 140 and the outlet 150 are not on the same plane and are perpendicular to each other. Specifically, in one case, such as... Figure 1 , Figure 3 , Figure 4 , Figure 7 As shown, the pipe interface of the inlet 140 is located on a bottom surface of the housing 110, and the pipe interface of the outlet 150 is located on the peripheral wall of the housing 110. The two pipe interfaces are not on the same plane and are perpendicular to each other. This facilitates the connection of the inlet 140 to the water tank 10 via the shortest possible pipe path. Simultaneously, the pipe interface of the outlet 150 extends from the peripheral wall of the housing 110 along the side of the cleaning head 1 parallel to the end face of the water tank 10 towards the cleaning roller, connecting to the surface of the cleaning roller via the shortest possible pipe path. Specifically, another case, such as... Figure 5 , Figure 6 , Figure 9 As shown, the pipe interface of the inlet 140 is located on the lower bottom wall of the periphery of the housing 110, which is located towards the front (outer) side. The pipe interface of the outlet 150 is located on the right side of the periphery of the housing 110, which is located towards the rear (inner) side. The two pipe interfaces are not on the same plane and are perpendicular to each other. This makes it convenient for the pipe interface of the inlet 140 to connect to the water tank 10 with the shortest connection pipe path. The reason for setting the pipe interface of the inlet 140 on the lower bottom wall of the periphery of the housing 110 is to reserve a 90-degree bending space for the pipe interface of the inlet 140 flowing out towards the end interface (not shown in the figure) of the water tank 10. At the same time, the pipe interface of the outlet 150 extends from the right side of the periphery of the housing 110, which is located towards the cleaning roller, along the side of the housing of the cleaning head 1, which is parallel to the end face of the water tank 10, and connects to the surface of the cleaning roller with the shortest connection pipe path. The water to be electrolyzed flows into the cavity 130 through the inlet 140, then flows along the periphery of the cavity in a semi-circular path through the electrolysis module 120, and finally flows out through the outlet 150. The pipe interface of the inlet 140 and the pipe interface of the outlet 150 are not on the same plane and are perpendicular to each other. This achieves both the drawing of clean water from the end of the water tank 10 to the electrolysis device 100 for electrolysis, and the utilization of the small thickness space between the end of the water tank 10 and the side wall of the cleaning head 1 to electrolyze the water, which has a bactericidal function. The electrolyzed water is rotated 90 degrees in the direction of entering the electrolysis device 100 before being sent to the surface of the cleaning roller. This ingeniously utilizes the fact that the water flow channel inside the electrolysis device 100 flows through the electrolysis module 120 via a semi-circular path, is electrolyzed, and then rotates 90 degrees before being sent out. This eliminates a 90-degree bend in the entire water supply path from the water tank 10 to the surface of the cleaning roller, improving the reliability of the water supply pipeline, reducing the flow resistance of the water supply pipeline, and simplifying and shortening the connection of the water supply pipeline between the electrolysis device and the water tank and the surface of the cleaning roller.

[0079] Furthermore, in the electrolysis apparatus 100 of this application, such as Figures 1 to 6 As shown, because the outlet 150 is higher than the overall electrolysis module 120, the clean water entering the cavity 130 through the inlet 140 will not immediately flow out of the outlet 150. The water to be electrolyzed flows into the cavity 130 through the inlet 140 and then along the periphery of the cavity in a semi-circular path through the electrolysis module 120 before flowing out of the outlet 150. This facilitates the thorough electrolysis of the clean water within the cavity 130 before further use; for example... Figure 7 As shown, the height of the inlet 140 of the electrolysis device 100 is level with the height of the lowest point of the clear water chamber of the clear water tank 10a. When the liquid level in the clear water chamber drops to the lowest point of the clear water chamber and is level with the height of the inlet 140, in other words, when the clear water in the clear water tank is used up, since at least part of the electrolysis module 120 is located below the inlet 140, even if the clear water drops to the lowest liquid level, a portion of electrolyzed water will still remain in the part of the cavity 130 where the electrolysis module 120 is installed that is below the inlet 140. This prevents the electrolysis module 120 from "dry burning" when it is powered on, thereby reducing the possibility of safety accidents.

[0080] Of course, the height of the outlet 150 can also be lower than the height of the overall electrolysis module 120. As long as it is higher than the lowest point of the electrolysis module 120, it can be ensured that at least a part of the electrolysis module 120 is submerged in the electrolysis water when it is powered on, and the phenomenon of "dry burning" will not occur.

[0081] Finally, the inlet 140 of the electrolysis device 100 in this application is installed at the same level as the lowest point of the clear water chamber, with a small height difference between them. Figure 7 , Figure 8 , Figure 9 As shown, when the water tank 10 is installed horizontally on the cleaning head 1, compared with the conventional method of setting the electrolysis device 100 on the machine body, and compared with the method of conveying clean water from the water tank set on the cleaning head to the electrolysis device 100 during use, the electrolysis device 100 of this application can convey the clean water in the clean water chamber to the electrolysis device 100 for electrolysis without overcoming a large potential energy difference during use, which can reduce energy consumption and shorten the path of conveying the clean water with sterilization function after electrolysis to the surface of the cleaning roller.

[0082] In an alternative embodiment, preferably, refer to Figure 2The inlet 140 is installed at a height no lower than the installation height of all areas of the electrolysis module 120, and lower than the installation height of the outlet 150. That is, the installation heights of the outlet 150, inlet 140, and electrolysis module 120 decrease sequentially from top to bottom. After clean water enters the cavity 130 through the inlet 140, it does not immediately flow out through the outlet 150. It is first fully electrolyzed at the electrolysis module 120 and fills all areas of the electrolysis module 120 until the level of the electrolyzed water entering the cavity 130 rises to the height of the outlet 150, and then it is discharged from the outlet 150 to the cleaning head 1. When the liquid level in the clear water chamber drops to be level with or below the inlet 140, the clear water will not continue to enter the cavity 130 through the inlet 140. The level of the electrolyzed water in the cavity 130 will begin to drop. After dropping to a height below the inlet 140, the electrolyzed water in this area will always remain in the cavity 130. In other words, the electrolysis module 120 will always be immersed in electrolyzed water, which can better prevent the electrolysis module from "dry burning" when energized, and further improve the safety of the electrolysis process.

[0083] In an optional embodiment, refer to Figure 1 , Figures 3 to 6 The housing 110 includes a bottom shell body 111 and a top cover body 113, which are interlocked to form a cavity 130. The interlocking of the bottom shell body 111 and the top cover body 113 to form the housing 110 not only facilitates assembly but also makes it convenient for operators to maintain and replace the electrolysis module 120 inside the housing 110.

[0084] Furthermore, the edges where the bottom shell body 111 and the top cover body 113 interlock can be sealed with sealing strips or sealant to prevent electrolyzed water from overflowing from the cavity 130 to the outside of the shell 110. Any of the existing technologies can be used for sealing, and no specific limitation is made here.

[0085] Furthermore, the bottom shell body 111 or the top cover body 113 is provided with an inlet 140 communicating with the cavity 130, and the bottom shell body 111 or the top cover body 113 is provided with an outlet 150 communicating with the cavity 130. The inlet 140 and the outlet 150 can be respectively provided on the bottom shell body or the top cover body, or the inlet 140 and the outlet 150 can be provided on one of the bottom shell body or the top cover body at the same time, without specific limitations. The specific location of the inlet 140 and the outlet 150 and whether they are provided on different covers depends on the shortest path for convenient connection of the pipes connecting the inlet 140 and the outlet 150 without any bends or constraints, which will not be elaborated here.

[0086] Furthermore, the pipe interfaces connecting the inlet 140 and the outlet 150 may not be on the same plane and may be perpendicular to each other. (Refer to...) Figures 1 to 6 The inlet 140 pipe interface is typically perpendicular to the end face of the water tank 10, facilitating direct connection of the lowest point of the clear water chamber of the water tank to the inlet 140 pipe interface via the shortest path. The outlet 150 pipe interface is typically parallel to the end face of the water tank 10, facilitating direct connection of the outlet 150 pipe interface to the cleaning head 1 housing side wall corresponding to the end of the water tank 10 via a pipe, extending to the surface of the cleaning head. Of course, as... Figure 5 , Figure 6 , Figure 9 As shown, although the pipe interface of the inlet 140 is parallel to the end face of the water tank 10, the pipe interfaces connecting the inlet 140 and the outlet 150 are not on the same plane and are perpendicular to each other. The pipe interface of the inlet 140 is perpendicular to the surface to be cleaned and downwards, and connects to the clean water chamber of the water tank 10 through a pipe. The pipe interface of the outlet 150 is perpendicular to the pipe interface of the inlet 140 and extends horizontally towards the cleaning roller along the side wall of the cleaning head 1 housing. This facilitates connecting the pipe interface of the outlet 150 to the surface of the cleaning roller through a pipe.

[0087] In an optional embodiment, refer to Figure 3 The inner side of the bottom shell 111 is provided with a mounting base 160, which is used to mount the electrolysis module 120. Specifically, refer to... Figure 3 The mounting base 160 can be located at the bottom of the base shell, and the overall height of the mounting base 160 is lower than that of the inlet 140. Further, refer to... Figure 3 The inlet 140 and outlet 150 are located on both sides of the mounting base 160.

[0088] In one specific embodiment, refer to Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 The outer surface of the faceplate body 113 is provided with a first protrusion 114 and a second protrusion 115 protruding outwards. Specifically, the first protrusion 114 is correspondingly arranged in the area of ​​the electrolysis module 120, providing more installation space for the electrolysis module 120 on the side of the cavity 130 facing the faceplate body 113; the second protrusion 115 is correspondingly arranged in the area above the electrolysis module 120 in the cavity 130, providing a larger gas-bearing space M for releasing the gas generated during the electrolysis process when the electrolyzed water flows towards the outlet 150. The first protrusion 114 and the second protrusion 115 provide a certain amount of hand space for the operator to easily fasten the faceplate body 113 to the bottom shell body 111, facilitating maintenance and replacement.

[0089] It should be noted that the aforementioned mounting base 160 is provided on the inner side of the bottom shell body 111. However, it is possible that the mounting base 160 is also provided inside the top cover body 113. The bottom shell body 111 and top cover body 113 mentioned here do not refer to any specific cover. In other words, the mounting base 160 only needs to be provided on either the bottom shell body 111 or the top cover body 113. Similarly, the aforementioned top cover body 113 has a first protrusion 114 and a second protrusion 115 protruding outwards on its outer surface. This also does not preclude the possibility that the outer surface of the bottom shell body 111 also has a first protrusion 114 and a second protrusion 115 protruding outwards. The first protrusion 114 and the second protrusion 115 only need to be provided on either the bottom shell body 111 or the top cover body 113.

[0090] Furthermore, such as Figure 4 , Figure 6 As shown, when the outlet 150 of the electrolysis device 100 can continuously output electrolyzed water, the electrolyzed water level H in the cavity 130 is slightly higher than that of the outlet 150. The space in the cavity 130 above the electrolyzed water level H becomes the gas space M. The bubbles generated during the electrolysis process first rise and are discharged into the gas space M, instead of turning 90 degrees and directly entering the water supply pipeline along the direction of the outlet 150. When the electrolyzed water cannot accommodate these excess gases, these gases are then mixed with the electrolyzed water and transported to the surface of the cleaning roller through the water supply pipeline. The setting of the gas space M makes it easy for users to observe the working status of the electrolysis device 100, and also facilitates the absorption of the gases discharged during the electrolysis process so that they do not occupy the space of the water supply pipeline and affect the amount of electrolyzed water delivered. The setting of the gas space M also helps to prevent the bubbles generated during the electrolysis process from being directly carried into the water supply pipeline, preventing excessive air bubbles in the cleaning water during the use of the floor scrubber and affecting the cleaning effect.

[0091] Furthermore, in an optional embodiment, the walls of the first protrusion 114 and the second protrusion 115 can be made of a transparent material to facilitate the operator's observation of the water level in the cavity 130, allowing for the addition of water to the clear water cavity or the shutdown of the electrolysis module 120 power supply based on observed changes in the water level. Simultaneously, the operator can also observe the operation of the electrolysis module 120 through the transparent first protrusion 114 for maintenance. On the other hand, as... Figure 8 , Figure 9As shown, the first protrusion 114 and the second protrusion 115 also facilitate the opening of corresponding observation windows (not shown in the figure) on the side of the housing of the cleaning head 1, allowing users to directly observe the working status inside the electrolysis device 100 through the transparent first protrusion 114 and the second protrusion 115. This allows users to first observe whether the electrolyzed water in the cavity 130 continues to bubble when the electrolysis device 100 malfunctions, thereby determining whether the electrolysis module 100 needs to be replaced or repaired.

[0092] In an optional embodiment, refer to Figure 4 , Figure 6 The electrolysis module 120 includes a positive electrode 121 and a negative electrode 122. A wiring port 112 is located at the bottom of the back of the base body 111. The positive electrode 121 and negative electrode 122 are spaced apart within the wiring port 112 on the back of the mounting base 160. The positive electrode 121 and negative electrode 122 are connected to a power source via external wires. The wiring port 112 can be further filled with waterproof adhesive to prevent water leakage and short circuits.

[0093] In an optional embodiment, refer to Figure 3 The electrolysis module 120 also includes a positive electrolytic plate 123 and a negative electrolytic plate 125. A threaded hole 161 is provided on the inner side of the mounting base 160 corresponding to the positive electrode 121 and the negative electrode 122. Mounting holes are provided on both the positive electrolytic plate 123 and the negative electrolytic plate 125 corresponding to the threaded hole 161. The positive electrolytic plate 123 is connected to the positive electrode 121 via an electrode screw 170, the threaded hole 161, and the mounting hole, and the negative electrolytic plate 125 is connected to the negative electrode 122. The positive electrolytic plate 123 and the negative electrolytic plate 125 are arranged in parallel. After power is applied, current flows sequentially through the positive electrode 121, the electrode screw 170, the positive electrolytic plate 123, the electrolyzed water, the negative electrolytic plate 125, and the negative electrode 122, forming a circuit to electrolyze the water flowing into the cavity.

[0094] Furthermore, refer to Figure 3 Both the positive electrode electrolytic plate 123 and the negative electrode electrolytic plate 125 have several pairs of flow holes 127. The diameter of the flow holes 127 is slightly smaller than that of the mounting holes for easy differentiation. The flow holes 127 can increase the fluidity of the electrolyzed water and increase the contact area between the electrolyzed water and the electrolytic plate.

[0095] In an optional embodiment, refer to Figure 3 The positive electrode electrolytic plate 123 has a first opening 124, and the negative electrode electrolytic plate 125 has a second opening 126. The first opening 124 and the second opening 126 are used to offset the positive electrode electrolytic plate 123, the negative electrode electrolytic plate 125 from the adjacent threaded hole 161.

[0096] In an optional embodiment, refer to Figure 3The electrolysis module 120 also includes an insulating frame 128, which is disposed between the positive electrode 121 and the negative electrode 122 to isolate the positive electrode 121 and the negative electrode 122 and prevent leakage. Correspondingly, the insulating frame 128 has a third opening 129 on both sides near the positive electrode 121 and the negative electrode 122, and the insulating frame 128 is offset from the two threaded holes 161 through the two third openings 129. The insulating frame 128 is also used to isolate the electrical conduction between the positive electrode electrolytic plate 123 and the negative electrode electrolytic plate 125, so that the positive electrode electrolytic plate 123 and the negative electrode electrolytic plate 125 always maintain their respective voltage potentials. This makes it easier for the water in the cavity 130 near the positive electrode electrolytic plate 123 and the negative electrode electrolytic plate 125 to ionize and decompose into effective bactericidal components.

[0097] Furthermore, multiple positive electrode electrolytic plates 123 and negative electrode electrolytic plates 125 can be provided, with the number of both being equal and arranged alternately. Multiple insulating frames 128 are also provided accordingly, with an insulating frame 128 provided between every two adjacent positive electrode electrolytic plates 123 and negative electrode electrolytic plates 125. This can further increase the number of electrolytic plates arranged in the flat cavity 130 space, increase the contact area between the electrolytic plates and the water to be electrolyzed, improve the water electrolysis efficiency in a limited space, and improve the sterilization efficiency of the electrolyzed water output by the electrolysis device 100.

[0098] Secondly, based on the same inventive concept, embodiments of this application disclose a floor scrubbing machine, with reference to... Figures 7 to 9 The cleaning device includes a water tank, a cleaning head 1, and an electrolysis device 100 as described in the first aspect. The electrolysis device 100 is located at the end of the water tank, the cleaning head 1 is connected to one side of the water tank, and the length direction of the cleaning head 1 is parallel to the length direction of the water tank. The cavity 130 of the electrolysis device 100 is connected to the water tank through a water inlet 140.

[0099] Furthermore, in this embodiment, the water tank can be a separate water tank or it can be part of an integrated water tank 10. Specifically, as follows... Figure 5 As shown, the integrated water tank 10 includes a clean water tank 10a and a wastewater tank 10b, which are separated by a partition (not shown in the attached drawing). The integrated water tank 10 has a bottom cover (not shown in the attached drawing) at its end. Both the bottom cover and the corresponding cleaning head housing have mating interfaces (not shown in the attached drawing). The electrolysis device 100 is fixed to the cleaning head housing mating interface at the end of the clean water tank 10a using bolts, screws, and other fasteners. The electrolysis device 100 connects to the outlet of the clean water tank 10a and the water supply pipe that delivers clean water to the cleaning roller of the cleaning head.

[0100] In an optional embodiment, preferably, the lowest point of the end of the water inlet pipe connected to the water inlet 140 near the clear water chamber can be installed on the bottom wall of the clear water chamber, that is, the height of the bottom wall of the clear water tank 10a is not lower than the height of the lowest point of the water inlet 140. This is beneficial because when the liquid level in the clear water chamber is about to reach the lowest point, the clear water can still flow into the cavity 130 through the water inlet 140, thereby reducing the possibility of "dry burning".

[0101] In the floor scrubber of this application embodiment, the electrolysis device 100 is installed on the housing of the cleaning head 1 corresponding to the end of the integrated water tank 10. While electrolyzing the clean water in the clean water tank 10a for use by the cleaning head 1, the water flow circulation of the clean water tank 10a and the wastewater tank 10b is not affected. This allows the integrated water tank 10 to integrate the functions of containing wastewater, providing clean water and electrolyzing cleaning water, and it is compact and easy to use.
