Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a flat electrolysis device and a floor scrubber. Background Art

[0002] With the advancement of science and technology, people's requirements for floor cleaning tools are gradually increasing. The first to appear is the vacuum cleaner, which relies on electricity to generate negative pressure to absorb garbage, dust, etc. on the ground. Based on the cleaning method and the circulation path of small and large particles of garbage, this type of technology is usually classified as air-dust circulation technology. However, due to the limitations of its working principle, the vacuum cleaner cannot clean some garbage and stains firmly attached to the ground. Therefore, a new "water-dust circulation" floor scrubber has appeared. The floor scrubber drives the cleaning cylinder to wipe the ground through the operation of the motor. At the same time, the floor scrubber is also equipped with a water supply system and a sink to clean the cleaning cylinder, thereby achieving floor cleaning.

[0003] At present, more and more floor scrubbers are beginning to integrate electrolysis modules in the water tank or body of the floor scrubber. The electrolysis module can electrolyze cleaning water into electrolyzed water containing bactericidal ingredients, and output it to the cleaning roller of the cleaning head to clean the floor.

[0033] In a second aspect, the present application discloses a floor scrubber, comprising a water tank, a cleaning head, and a flat electrolysis device as described in the first aspect and arranged at an end of the water tank.

[0034] Based on the above technical solution, the beneficial effects of the present invention compared with the prior art are as follows:

[0035] In the electrolysis device of the present application, the electrolysis module is arranged in a hollow shell having a cavity. During actual installation, the electrolysis device can be arranged on a 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 a water pipe that conveys 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, clean water enters at least part of the electrolysis module of the cavity of the electrolysis device from the water inlet under the action of gravity to be fully electrolyzed. 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 and flows through the electrolysis module along the peripheral wall of the cavity in a semi-circular path before flowing out of the water outlet, which is conducive to the clean water being fully electrolyzed in the cavity. The electrolysis device has a simple and compact structure. It can electrolyze clean water and deliver clean water with a sterilization function to the surface of the cleaning roller without the need for cooperation with other structures. The electrolysis device occupies a small volume as a whole, which can greatly reduce the overall weight of the floor scrubber, thereby making the floor scrubber using the electrolysis device lighter and more convenient to use.

[0036] The electrolysis device of the present application adopts a flat structure as a whole and is installed on the side wall of the cleaning head shell corresponding to the end of the water tank. The area of ​​the flat-structured electrolysis device projected on the end of the water tank is smaller than the area of ​​the end of the water tank itself, and only occupies a smaller space of the shell side wall thickness. The pipe interface of the water inlet of the electrolysis device and the pipe interface of the water outlet are not on the same plane and are perpendicular to each other, so that the pipe interface of the water inlet is connected to the water tank with the shortest connecting pipe path. At the same time, the pipe interface of the water outlet extends from the peripheral wall of the electrolysis device shell along the side edge of the cleaning head 1 parallel to the end face of the water tank end to the cleaning roller and is connected to the surface of the cleaning roller with the shortest connecting pipe path. The electrolysis device as a whole and the matching connecting pipes occupy a small volume, which can greatly reduce the overall weight of the floor scrubber, thereby making the floor scrubber using the electrolysis device more portable, and can also simplify and shorten the connection of the water supply pipe between the electrolysis device and the water tank and the surface of the cleaning roller.

[0037] The electrolysis device in the present application is independently arranged in the clean water chamber of the water tank. Each time electrolysis is performed, only the liquid entering the chamber is electrolyzed, and there is no need to electrolyze the liquid in the entire clean 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.

[0038] The electrolysis device in the present application is close to the end of the water tank, and the installation position is flush with the lowest point of the clean water chamber, and 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 fuselage and transporting clean water from the water tank set on the cleaning head to the electrolysis device upward when in use, the electrolysis device of the present application does not need to overcome a large potential energy difference when in use to transport the clean water in the clean water chamber to the electrolysis device for electrolysis, which can reduce energy consumption and shorten the path for transporting the clean water with sterilization function after electrolysis to the surface of the cleaning roller.

On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0061] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0063] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] The present invention will be further described below in conjunction with specific embodiments, but the present invention is not limited thereto.

[0065] The applicant found that in some existing floor scrubbers, the electrolysis device is integrated and installed in the water tank. For example, the applicant's Chinese patent with publication number CN116982887A discloses a cleaning device, in which a water electrolysis module is provided at the bottom of the clean water chamber, and the water tank is equipped with a transfer box for supplying electricity to the water electrolysis module away from the clean water outlet, so as to avoid short circuits between the power supply electrodes caused by water dripping; at the same time, the clean water tank sealed bottom cover structure is used in conjunction with the power supply transfer box, so as to ensure complete insulation isolation between the water tank and the power supply electrodes of the water electrolysis module, and ensure a certain degree of maintainability of the connection of the water electrolysis module, which is convenient for organizing production and for consumers to replace the water electrolysis module by themselves.

[0066] The applicant also found that in some other floor scrubbers, the electrolysis device is integrated and installed in the floor scrubber body, such as the applicant's Chinese patent with the authorization announcement number CN220089382U, which discloses a body shell, a floor scrubber body and a floor scrubber. The body shell includes a shell body, a bottom shell body and a cover body; the floor scrubber body includes a water electrolysis device and a water pump; the shell body includes a first mounting surface and a second mounting surface that are arranged oppositely; the first mounting surface is provided with a water electrolysis device mounting portion to install the water electrolysis device; the second mounting surface is provided with a water pump accommodating compartment to accommodate the water pump; a through hole is provided on the shell body, and the water electrolysis device includes an electrolysis water tank, so that the electrolysis water tank at least partially passes through the through hole; the bottom shell body and the cover body are respectively installed on the first mounting surface and the second mounting surface.

[0067] In summary, the applicant concluded that the electrolysis device configured in the existing "water-dust circulation" floor scrubber, whether it is set at the bottom of the water tank or on the body of the machine, inevitably occupies a large volume, which easily increases the overall weight of the floor scrubber and makes the floor scrubber inconvenient to use; at the same time, the electrolysis device configured in the existing floor scrubber often electrolyzes the clean water in the entire water tank when working, and the concentration of the bactericidal components in the produced electrolyzed water is not high.

[0068] Therefore, in order to reduce the volume occupied by the electrolysis device in the floor scrubber, reduce the overall weight of the floor scrubber, and at the same time improve the efficiency of the electrolysis device in electrolyzing clean water to produce electrolyzed water containing high-concentration bacteria-killing components, and in order to simplify and shorten the connection between the electrolysis device and the water tank and the surface of the cleaning roller, the applicant further developed and made the present invention.

[0069] In a first aspect, the present application embodiment provides an electrolysis device 100, referring to Figures 1 to 9 The electrolysis device 100 is flat, and includes a shell 110 and an electrolysis module 120; the shell 110 is hollow inside to form a cavity 130; the electrolysis module 120 is arranged in the cavity 130; the shell 110 is provided with a water inlet 140 connected to the cavity 130, the water inlet 140 is connected to the water tank 10 of the floor scrubber, and the shell 110 is provided with a water outlet 150 connected to the cavity 130, the water outlet 150 is connected to the surface of the cleaning roller (not shown in the drawings) installed on the shell of the cleaning head 1 through a pipeline; at least part of the electrolysis module 120 is located below the water inlet 140.

[0070] Specifically, Figure 7 , Figure 8 , Fig. 9As shown, the electrolysis device 100 in the present application can be set on the shell of the cleaning head 1 corresponding to the end of the water tank 10 during actual installation. The water tank 10 includes a partition (not shown in the figure) arranged inside the water tank 10, which is divided into a clean water tank 10a and a sewage tank 10b arranged up and down or left and right. Preferably, the clean water tank 10a is arranged at the upper part of the water tank 10, and the sewage tank 10b is arranged at the lower part of the water tank 10. The inside of the clean water tank 10a is hollow to form a clean water cavity that can accommodate clean water. The electrolysis device 100 is connected to the water outlet of the clean water tank 10a (not shown in the figure) and the water pipe (not shown in the figure) that transports clean water to the cleaning roller of the cleaning head 1. The electrolysis device 100 in the present application occupies a small volume, which can greatly reduce the overall weight of the floor scrubber, making the floor scrubber lighter and more convenient to use.

[0071] In addition, if Figure 2 , Figure 3 As shown, the chamber 130 is independently arranged in the housing 110, and the housing 110 is connected to the clean water chamber and the cleaning roller of the cleaning head 1 through the water inlet 140 and the water outlet 150. Therefore, the electrolysis device 100 is independently arranged from the clean water chamber, and each electrolysis only needs to electrolyze the liquid entering the chamber 130, and does not need to electrolyze the liquid in the entire water tank. The electrolysis space is small, which can increase the concentration of effective bactericidal components in the electrolyzed water electrolyzed by the electrolysis device 100, and improve the bactericidal efficiency of the produced electrolyzed water.

[0072] In one or some alternative embodiments, Figure 7 , Figure 8 , Fig. 9 As shown, the area of ​​the shell 110 projected on the end plane of the water tank 10 is smaller than the area of ​​the end plane of the water tank 10 itself. In this way, the limited space between the end plane of the water tank 10 and the shell side wall of the cleaning head 1 can be effectively utilized, so that the electrolysis device 100 can complete the electrolysis of the clean water drawn from the water tank 10 in the narrow space, thereby increasing the concentration of effective bactericidal components in the electrolyzed water electrolyzed by the electrolysis device 100.

[0073] Of course, in order to more conveniently connect the connecting pipes of the water inlet 140 and the water outlet 150, as Figure 8 , Fig. 9 As shown, the area of ​​the shell 110 projected on the end plane of the water tank 10 can slightly exceed the area framed by the end plane of the water tank 10 itself, and the excess part is just reserved for the water inlet 140 and / or the water outlet 150 for pipe connection, which is more conducive to improving the space utilization rate inside the shell of the cleaning head 1, making the floor scrubber more lightweight and convenient to use.

[0074] In an optional embodiment, on the electrolysis device 100 in the present application, the water inlet 140 and the water outlet 150 are each a pipe interface connected to the chamber 130; the pipe interface of the water inlet 140 and the pipe interface of the water outlet 150 are not on the same plane and are perpendicular to each other. Specifically, in one case, Figure 1 , Figure 3 , Figure 4 , Figure 7 As shown, the pipeline interface of the water inlet 140 is arranged on a bottom surface of the shell 110, and the pipeline interface of the water outlet 150 is arranged on the peripheral wall of the shell 110. The two pipeline interfaces are not on the same plane and are perpendicular to each other, so that the pipeline interface of the water inlet 140 is convenient for connecting to the water tank 10 with the shortest connecting pipeline path. At the same time, the pipeline interface of the water outlet 150 extends from the peripheral wall of the shell 110 along the side of the shell of the cleaning head 1 parallel to the end face of the end of the water tank 10 to the cleaning roller and connects to the surface of the cleaning roller with the shortest connecting pipeline path. Specifically, in another case, as Figure 5 , Figure 6 , Fig. 9 As shown, the pipe interface of the water inlet 140 is arranged on the lower bottom wall of the peripheral wall of the shell 110 near the front (outside), and the pipe interface of the water outlet 150 is arranged on the right wall of the peripheral wall of the shell 110 near the back (inside). The two pipe interfaces are not on the same plane and are perpendicular to each other, so that the pipe interface of the water inlet 140 is convenient for connecting to the water tank 10 with the shortest connecting pipe path. The reason for setting the pipe interface of the water inlet 140 on the lower bottom wall of the peripheral wall of the shell 110 near the front (outside) is to reserve a bending space of 90 degrees for the pipe to flow out of the pipe interface of the water inlet 140 toward the end interface of the water tank 10 (not marked in the drawings). At the same time, the pipe interface of the water outlet 150 extends from the right wall of the peripheral wall of the shell 110 near the back (inside) along the shell side of the cleaning head 1 parallel to the end face of the water tank 10 to the cleaning roller and is connected to the surface of the cleaning roller with the shortest connecting pipe path. The water to be electrolyzed flows into the chamber 130 from the water inlet 140, flows along the peripheral wall of the chamber around the semi-circular path through the electrolysis module 120, and then flows out from the water outlet 150. The pipe interface of the water inlet 140 and the pipe interface of the water outlet 150 are not on the same plane and are perpendicular to each other. In this way, clean water is led out from the end of the water tank 10 to the electrolysis device 100 for electrolysis, and at the same time, the electrolyzed water with sterilization function is taken advantage of in the smaller thickness space between the end of the water tank 10 and the side wall of the shell of the cleaning head 1. The electrolyzed water is turned 90 degrees along the direction it enters the electrolysis device 100 and then delivered to the surface of the cleaning roller. The water flow path inside the electrolysis device 100 is cleverly utilized to flow through the electrolysis module 120 in a semi-circular path and then turn 90 degrees before being delivered. A 90-degree adapter elbow is omitted in the entire water delivery passage from the water tank 10 to the surface of the cleaning roller, thereby improving the reliability of the water delivery pipeline, reducing the flow resistance of the water delivery pipeline, and simplifying and shortening the connection of the water delivery pipeline between the electrolysis device and the water tank and the surface of the cleaning roller.

[0075] Furthermore, in the electrolysis device 100 of the present application, Figures 1 to 6 As shown, since the height of the water outlet 150 is higher than the height of the entire electrolysis module 120, the clean water will not flow out of the water outlet 150 immediately after entering the cavity 130 through the water inlet 140. The water to be electrolyzed flows into the cavity 130 from the water inlet 140, flows along the peripheral wall of the cavity around the semi-circular path through the electrolysis module 120, and then flows out of the water outlet 150. This is conducive to the clean water being fully electrolyzed in the cavity 130 before being further used; Figure 7 As shown, the height of the water inlet 140 of the electrolysis device 100 is flush with the height of the lowest point of the clean water chamber of the clean water tank 10a. When the liquid level of the clean water chamber drops to the lowest point of the clean water chamber and is flush with the height of the water inlet 140, in other words, when the clean water in the clean water tank is used up, since at least part of the electrolysis module 120 is located below the water inlet 140, even if the clean water drops to the lowest liquid level, a part of electrolyzed water will still remain in the part of the cavity 130 where the electrolysis module 120 is installed that is lower than the water inlet 140, so that the electrolysis module 120 will not "dry burn" when powered on, thereby reducing the possibility of safety accidents.

[0076] Of course, the height of the water outlet 150 can also be lower than the height of the entire electrolysis module 120. As long as it is higher than the lowest point of the electrolysis module 120, it can ensure that at least a part of the electrolysis module 120 is immersed in electrolytic water when the electrolysis module 120 is powered on, and the phenomenon of "dry burning" will not occur.

[0077] Finally, the installation position of the water inlet 140 of the electrolysis device 100 in the present application can be flush with the lowest point of the clean water chamber, and the height difference between the two is small, such as Figure 7 , Figure 8 , Fig. 9 As shown, when the water tank 10 is horizontally installed on the cleaning head 1, compared with the conventional method of setting the electrolysis device 100 on the body, and compared with the method of transporting clean water from the water tank set on the cleaning head to the electrolysis device 100 upward during use, the electrolysis device 100 of the present application can transport 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 for transporting the clean water with sterilization function after electrolysis to the surface of the cleaning roller.

[0078] In an optional embodiment, as preferred, refer to Figure 2, the height of the water inlet 140 is not lower than the installation height of all areas of the electrolysis module 120, and is lower than the height of the water outlet 150, that is, the installation heights of the water outlet 150, the water inlet 140 and the electrolysis module 120 are successively reduced from top to bottom. After the clean water enters the cavity 130 from the water inlet 140, it will not flow out through the water outlet 150 immediately, but will be fully electrolyzed at the electrolysis module 120 first, and will soak all areas of the electrolysis module 120, until the level of the electrolyzed water entering the cavity 130 rises to the height of the water outlet 150, and then will be discharged from the cleaning head 1 through the water outlet 150. When the liquid level in the clean water chamber drops to the same level as the water inlet 140 or lower than the water inlet 140, the clean water no longer continues to enter the cavity 130 through the water inlet 140, and the electrolyzed water level in the cavity 130 begins to drop. After dropping to a height below the water inlet 140, the electrolyzed water in this area always remains in the cavity 130. In other words, the electrolysis module 120 is always immersed in the electrolyzed water, which can better prevent the electrolysis module from "dry burning" when powered on, further improving the safety of the electrolysis process.

[0079] In an alternative embodiment, referring to Figure 1 , Figures 3 to 6 The housing 110 includes a bottom housing body 111 and a cover body 113, which are buckled together to form a cavity 130. The bottom housing body 111 and the cover body 113 are buckled together to form the housing 110, which is not only easy to assemble, but also convenient for operators to maintain and replace the electrolytic module 120 in the housing 110.

[0080] Furthermore, the edges where the bottom shell body 111 and the cover body 113 are buckled together can be sealed by sealing strips or sealants to prevent the electrolyzed water from overflowing from the cavity 130 to the outside of the housing 110. The sealing method can be any one of the existing technologies and is not specifically limited here.

[0081] Furthermore, a water inlet 140 communicating with the cavity 130 is provided on the bottom shell body 111 or the surface cover body 113, and a water outlet 150 communicating with the cavity 130 is provided on the bottom shell body 111 or the surface cover body 113. The water inlet 140 and the water outlet 150 can be respectively arranged on the bottom shell body or the surface cover body, or the water inlet 140 and the water outlet 150 can be simultaneously arranged on one of the bottom shell body or the surface cover body, which is not specifically limited here. The specific arrangement positions of the water inlet 140 and the water outlet 150 and whether they are arranged on different cover bodies can be arranged according to the specific connection of the water inlet 140 and the water outlet 150. The pipeline arrangement is convenient and the path is the shortest and is not subject to any bending constraints, which will not be repeated here.

[0082] Furthermore, the pipe interfaces connecting the water inlet 140 and the water outlet 150 may not be on the same plane and the two may be perpendicular to each other. Figures 1 to 6 The pipe interface of the water inlet 140 is usually perpendicular to the end face of the water tank 10, so that the lowest point of the clean water chamber of the water tank can be directly connected to the pipe interface of the water inlet 140 through the pipe in the shortest way. The pipe interface of the water outlet 150 is usually parallel to the end face of the water tank 10, so that the pipe interface of the water outlet 150 can be directly extended to the surface of the cleaning head 1 through the pipe on the side wall of the cleaning head 1 corresponding to the end of the water tank 10. Of course, if Figure 5 , Figure 6 , Fig. 9 As shown, although the pipe interface of the water inlet 140 is parallel to the end face of the water tank 10, the pipe interfaces connecting the water inlet 140 and the water outlet 150 are not on the same plane and are perpendicular to each other. The pipe interface of the water inlet 140 is perpendicular to the surface to be cleaned and downward and connected to the clean water chamber of the water tank 10 through a pipe, and the pipe interface of the water outlet 150 is perpendicular to the pipe interface of the water inlet 140 and horizontally points to the direction of the cleaning roller and extends forward along the side wall of the cleaning head 1 shell, so that it is convenient to connect the pipe interface of the water outlet 150 to the surface of the cleaning roller through a pipe.

[0083] In an alternative embodiment, referring to Figure 3 , a mounting seat 160 is provided on the inner side of the bottom shell body 111, and the mounting seat 160 is used to mount the electrolysis module 120. Specifically, referring to Figure 3 The mounting seat 160 can be disposed at the bottom of the bottom shell body, and the overall height of the mounting seat 160 is lower than the water inlet 140. Figure 3 The water inlet 140 and the water outlet 150 are respectively located on two sides of the mounting seat 160 .

[0084] In a specific embodiment, referring to Figure 3 , Figure 4 , Figure 6 , Figure 8 , Fig. 9 , the outer side surface of the face cover body 113 is provided with a first protrusion 114 and a second protrusion 115 protruding outward. Specifically, the first protrusion 114 is arranged corresponding to the electrolysis module 120 area, and the first protrusion 114 provides more installation space for the electrolysis module 120 on the side facing the face cover body 113 in the cavity 130; the second protrusion 115 is arranged corresponding to the area above the electrolysis module 120 in the cavity 130, and the second protrusion 115 provides a larger gas storage space M for releasing the gas generated in the electrolysis process when the electrolyzed water flows toward the water outlet 150 after electrolysis. The first protrusion 114 and the second protrusion 115 can provide a certain hand-held space for the operator to facilitate the buckling of the face cover body 113 and the bottom shell body 111, so as to facilitate maintenance and replacement.

[0085] It should be noted that the aforementioned provision of a mounting seat 160 on the inner side of the bottom shell body 111 does not exclude the possibility that the mounting seat 160 is provided in the face cover body 113, and the bottom shell body 111 and the face cover body 113 mentioned here do not refer to any specific cover body. In other words, the mounting seat 160 only needs to be provided on either the bottom shell body 111 or the face cover body 113. Similarly, the aforementioned provision of a first protrusion 114 and a second protrusion 115 protruding outward on the outer side of the face cover body 113 does not exclude the possibility that the outer side of the bottom shell body 111 is provided with a first protrusion 114 and a second protrusion 115 protruding outward, and the first protrusion 114 and the second protrusion 115 only need to be provided on either the bottom shell body 111 or the face cover body 113.

[0086] Further, such as Figure 4 , Figure 6 As shown, when the water 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 the water outlet 150, and the space of the cavity 130 above the electrolyzed water level H becomes the gas-containing space M. The bubbles generated during the electrolysis process will first rise and be discharged into the gas-containing space M, and will not directly turn 90 degrees and enter the water pipeline directly along the direction of the water outlet 150. When the electrolyzed water cannot contain these excess gases, these gases will be mixed with the electrolyzed water and transported to the surface of the cleaning roller through the water pipeline. The setting of the gas-containing space M can facilitate the user to observe the working state of the electrolysis device 100, and it is also convenient to absorb the gases discharged during the electrolysis process so that these gases do not occupy the space of the water pipeline and affect the water delivery volume of the electrolyzed water; the setting of the gas-containing space M also helps to prevent the bubbles generated during the electrolysis process from being directly brought into the water pipeline, and prevent the floor scrubber from having too many bubbles in the cleaning water during use and affecting the cleaning effect.

[0087] 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 to observe the liquid level of the electrolyzed water in the chamber 130, so that water can be added to the clean water chamber or the power supply of the electrolysis module 120 can be turned off according to the observed liquid level changes. At the same time, the operator can also observe the working condition of the electrolysis module 120 through the transparent first protrusion 114, so as to repair the electrolysis module 120. On the other hand, if Figure 8 , Fig. 9As shown, the first protrusion 114 and the second protrusion 115 also facilitate the opening of a corresponding observation window (not marked in the drawings) on the side of the shell of the cleaning head 1, so that the user can directly observe the internal working status of the electrolysis device 100 through the transparent first protrusion 114 and the second protrusion 115, so that when the electrolysis device 100 fails, the user can first observe whether the electrolyzed water in the cavity 130 continues to bubble, so as to determine whether the electrolysis module 100 needs to be replaced or repaired.

[0088] In an alternative embodiment, referring to Figure 4 , Figure 6 The electrolysis module 120 includes a positive electrode 121 and a negative electrode 122. A wiring port 112 is provided at the bottom of the back of the bottom shell body 111. The positive electrode 121 and the negative electrode 122 are spaced apart in the wiring port 112 on the back of the mounting seat 160. The positive electrode 121 and the negative electrode 122 are connected to the power supply through external wires. The wiring port 112 can be further filled with waterproof glue to prevent water from overflowing and causing a short circuit.

[0089] In an alternative embodiment, referring to Figure 3 The electrolysis module 120 also includes a positive electrode electrolyte sheet 123 and a negative electrode electrolyte sheet 125. The inner side of the mounting seat 160 is provided with a threaded hole 161 at the place corresponding to the positive electrode 121 and the negative electrode 122. The positive electrode electrolyte sheet 123 and the negative electrode electrolyte sheet 125 are provided with mounting holes at the places corresponding to the threaded hole 161. Among them, the positive electrode electrolyte sheet 123 is connected to the positive electrode 121, the negative electrode electrolyte sheet 125 is connected to the negative electrode 122 through the electrode screw 170, the threaded hole 161 and the mounting hole. The positive electrode electrolyte sheet 123 and the negative electrode electrolyte sheet 125 are arranged in parallel. After power is turned on, the current can pass through the positive electrode 121, the electrode screw 170, the positive electrode electrolyte sheet 123, the electrolyzed water, the negative electrode electrolyte sheet 125 and the negative electrode 122 in sequence to form a loop to electrolyze the clean water flowing into the cavity.

[0090] Further, see Figure 3 The positive electrode electrolyte sheet 123 and the negative electrode electrolyte sheet 125 are both provided with a plurality of convection holes 127, the aperture of which is slightly smaller than the aperture of the mounting hole for easy distinction. The convection holes 127 can increase the fluidity of the electrolyzed water and increase the contact area between the electrolyzed water and the electrolyte sheet.

[0091] In an alternative embodiment, referring to Figure 3 The positive electrolyte sheet 123 is provided with a first opening 124 , and the negative electrolyte sheet 125 is provided with a second opening 126 . The first opening 124 and the second opening 126 are used to stagger the positive electrolyte sheet 123 , the negative electrolyte sheet 125 and the adjacent threaded holes 161 .

[0092] In an alternative embodiment, referring 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 and is used to isolate the positive electrode 121 and the negative electrode 122 to prevent leakage; accordingly, the insulating frame 128 is provided with third openings 129 on both sides close to the positive electrode 121 and the negative electrode 122, and the insulating frame 128 is staggered with 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 electrolyte sheet 123 and the negative electrode electrolyte sheet 125, so that the positive electrode electrolyte sheet 123 and the negative electrode electrolyte sheet 125 are always processed at their respective voltage potentials, which is more conducive to the water in the cavity 130 near the positive electrode electrolyte sheet 123 and the negative electrode electrolyte sheet 125 to be more easily ionized and decomposed into effective bactericidal components.

[0093] Furthermore, multiple positive electrode electrolyte sheets 123 and negative electrode electrolyte sheets 125 can be provided and the number of the two is equal and they are arranged in sequence and spaced apart from each other. Multiple insulating frames 128 are also provided accordingly, and an insulating frame 128 is provided between every two adjacent positive electrode electrolyte sheets 123 and negative electrode electrolyte sheets 125. This can further increase the space in the flat cavity 130 to provide more electrolyte sheets, increase the contact area between the electrolyte sheets and the clean 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.

[0094] In the second aspect, based on the same inventive concept, the present application embodiment discloses a floor scrubber, referring to Figures 7 to 9 The cleaning device comprises a water tank, a cleaning head 1 and an electrolysis device 100 as in the first aspect. The electrolysis device 100 is arranged 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, and the cavity 130 of the electrolysis device 100 is connected to the water tank through the water inlet 140.

[0095] Furthermore, in this embodiment, the water tank can be a separate water tank or a part of the integrated water tank 10. Figure 5 As shown, the integrated water tank 10 includes a clean water tank 10a and a dirty water tank 10b, and the clean water tank 10a and the dirty water tank 10b are separated by a partition (not shown in the figure). A bottom cover (not shown in the figure) is provided at the end of the integrated water tank 10, and the bottom cover and the cleaning head shell corresponding to the bottom cover are provided with a docking interface (not shown in the figure) that docks with each other, wherein the electrolysis device 100 is fixed to the cleaning head shell docking interface corresponding to the bottom cover at the end of the clean water tank 10a by fasteners such as bolts and screws, and the electrolysis device 100 is connected to the water outlet of the clean water tank 10a and the water pipe that transports clean water to the cleaning roller of the cleaning head.

[0096] In an optional embodiment, as a preference, the lowest point of the end of the water inlet pipe connected to the water inlet 140 close to the clean water chamber can be installed on the bottom wall of the clean water chamber, that is, the height of the bottom wall of the clean water tank 10a is not lower than the lowest point of the water inlet 140. This is conducive to the clean water still flowing into the containing cavity 130 through the water inlet 140 when the liquid level in the clean water chamber is about to reach the lowest point, thereby reducing the possibility of "dry burning" phenomenon.

[0097] In the floor scrubber in the embodiment of the present application, the electrolysis device 100 is installed on the shell of the cleaning head 1 corresponding to the end of the integrated water tank 10. While the clean water in the clean water tank 10a is electrolyzed for use by the cleaning head 1, it does not affect the water circulation of the clean water tank 10a and the sewage tank 10b themselves, so that the integrated water tank 10 integrates the functions of accommodating sewage, providing clean water and electrolyzing clean water, and has a compact structure and is easy to use.
