The inventors have found that in the prior art floor cleaning appliances typically have the electrolysis device located directly within the fresh water tank. As disclosed in the publication No. CN217118332U, a cleaning apparatus having a disinfectant generating device is disclosed, comprising: an apparatus main body portion having an inner cavity, a first tank being provided inside the inner cavity of the apparatus main body portion, the first tank being for containing a cleaning liquid; and a disinfectant generating device at least partially provided inside the first casing, the disinfectant generating device generating a disinfectant such that the cleaning liquid of the first casing contains the disinfectant, the disinfectant generating device including an electrolysis device. This kind of equipment, in order to reduce the frequency of user's change water supply installation, it is great to need to set up water supply installation's water storage region, and just electrolyzed water is diluted by whole case water, and concentration reduces, and the disinfection dynamics is low, in order to guarantee the concentration of electrolyzed water in order to reach expected cleaning performance, and electrolytic device just can let the electrolyzed water flow out after electrolyzing the water in whole clean water tank into electrolyzed water, and whole process needs the user to wait for a long time, seriously influences user's use experience to ground cleaning equipment. In addition, the electric connection between the electrolysis device and the power receiving device is complex, and the difficulty in production and manufacture of the water supply device is increased.

The inventors have also found that in some improved floor scrubber products, at least a portion of the water electrolysis module is mounted within the water tank. As disclosed in the publication No. CN217161995U, CN217185947U, a water supply device of a floor cleaning apparatus is disclosed, comprising: the water storage tank is provided with a containing groove with one side open and a water storage outlet; the electrolytic water tank is arranged in the accommodating groove and is selectively communicated with the water storage outlet, and the electrolytic water tank is provided with an electrolytic water outlet; the electrolysis module is arranged in the electrolysis water tank to form electrolysis water in the electrolysis water tank; and the base is arranged at the bottom of the electrolytic water tank and is connected with the side wall of the containing groove. As another patent publication No. CN217185944U, CN217185945U, CN217185946U, CN 217792858U, a water supply device of a floor cleaning apparatus is disclosed, comprising: a water storage tank; the electrolytic water tank is selectively communicated with the water storage tank and is provided with an electrolytic water outlet; the electrolysis module is arranged in the electrolysis water tank to form electrolysis water in the electrolysis water tank; and the power connection module is arranged in the electrolytic water tank and is electrically connected with the electrolytic module. Although the water tank is divided into a water storage tank and an electrolytic water tank by the devices, the two parts are communicated, even if an optional communication structure is added, an additional control means of a control system is added, and meanwhile, the additional optional communication structure also increases the complexity of the whole water tank, increases the production and manufacturing cost and cannot meet the expectations of the inventor.

Therefore, how to provide the electrolyzed water efficiently shortens the time for a user to wait for the water tank to generate the electrolyzed water, further reduces the installation complexity of the electrolyzed water module and reduces the control complexity of the electrolyzed water module, which are all technical problems to be solved urgently at present. The inventors have further developed the present utility model.

In a first aspect, an embodiment of the present utility model provides a water electrolysis apparatus 100, referring to fig. 1, 2 and 9, the water electrolysis apparatus 100 is mounted to a scrubber body 200 provided with a water pump and a cleaning liquid channel, the water electrolysis apparatus 100 includes a housing (not shown), an electrolysis module 40 and a control module 30; the inlet end of the shell is connected with the water pump water outlet (not shown in the figure), the outlet end of the shell is connected with the cleaning liquid channel input port (not shown in the figure) and is used for containing and conveying electrolytic water to the scrubber head 300 in a long and narrow space in the gravity direction in front of the cleaning liquid channel, the shell comprises an upper shell slender channel 10 and a lower shell containing cavity 20 which are connected with each other, and the volume of the containing cavity 20 is larger than that of the slender channel 10; the electrolysis module 40 is arranged in the containing cavity 20, and the electrolysis module 40 can electrolyze the liquid in the containing cavity 20 to generate electrolyzed water rich in sodium hypochlorite; the control module 30 is disposed outside the cavity 20, and the control module 30 is electrically connected to and controls the electrolysis module 40; wherein, the control module 30 controls the electrolytic module 40 to work according to the instruction of the main control unit of the scrubber.

According to the utility model, the accommodating cavity 20 of the water electrolysis device 100 is arranged independently of the water tank of the floor washing machine, so that only the liquid entering the accommodating cavity 20 can be electrolyzed, the whole water tank is not required to be electrolyzed, the ionization space is small, the electrolysis efficiency can be improved, and the electrolysis time can be reduced. By arranging the long and narrow channel 10 at the inlet end of the containing cavity 20, the water containing capacity of the long and narrow channel 10 is small, and by arranging the long and narrow channel 10 as a long and narrow channel, the height difference is formed between the liquid inlet pipe joint 101 of the long and narrow channel 10 and the containing cavity 20, so that the liquid inlet amount of the containing cavity 20 in unit time is reduced, the influence of newly introduced liquid on the electrolytic process in the containing cavity 20 is reduced, the concentration of the electrolytic water in the containing cavity 20 is not greatly diluted, and the electrolytic efficiency can be improved, the waiting time of a user is reduced, and the user experience is improved. Compared with the electrolytic cavity which is independently arranged with the water tank in the prior art, the utility model realizes water diversion by arranging the long and narrow long channel 10 and utilizing the height difference between the long and narrow channel 10 and the containing cavity 20, does not need a complex water diversion control structure, and reduces the manufacturing cost of the device. At the same time, the liquid inlet pipe joint 101 at the top end of the long and narrow long and thin channel 10 with a larger height difference is arranged between the two, namely, the liquid which is electrolyzed in the liquid containing cavity 20 can be reversely poured into the liquid inlet pipe joint 101 under the condition of not overcoming the lift pressure of the water pump only when the movement acceleration of the extremely high water electrolysis device 100 is enough to overcome the corresponding pressure of the height difference. If the superposition of the lift pressure of the water pump is taken into consideration, the user cannot generate the movement acceleration of the water electrolysis device 100 by the ordinary pulling action, so that the electrolyzed liquid in the containing cavity 20 can be reversely poured into the liquid inlet pipe joint 101 under the condition of not overcoming the lift pressure of the water pump. That is, the water electrolysis apparatus 100 having the elongated channels 10 with a large height difference can further maintain a high electrolysis efficiency by preventing the back-flow loss of the electrolyzed solution in addition to more intensively electrolyzing and separating a small amount of liquid to generate a sodium hypochlorite solution of a high concentration to increase the electrolysis efficiency. Further, the height of the elongated channel 10 may be set according to actual needs, or the liquid inlet amount may be controlled by controlling the height ratio or the volume ratio of the elongated channel 10 to the cavity 20, for example, the height ratio of the elongated channel 10 to the cavity 20 may be 1.5:1 to 5:1, so that the liquid inlet pipe joint 101 and the containing cavity 20 have a preset height difference.

In one or some alternative embodiments, referring to fig. 3, 6 and 9, the elongated channel 10 is η -shaped, and the elongated channel 10 includes a liquid inlet pipe joint 101 with a downward opening in a gravity direction, a slow flow portion 102 for smoothly diverting the fed liquid against the gravity, and an elongated liquid inlet channel 103 extending downward in the gravity direction and smoothly connecting the slow flow portion 102. The opening of the liquid inlet pipe joint 101 is downward, so that the pipeline can be conveniently connected to the liquid inlet pipe joint 101 from the water outlet of the water pump in the production and manufacturing process, the liquid is output to the water pump to be upwards fed into the slender channel 10 against the gravity, the initial flow rate of the liquid entering the slender channel 10 can be reduced, and the main control unit of the floor scrubber can conveniently and accurately control the flow rate of the liquid fed into the slender channel 10 by the water pump; the slow flow part 102 is smoothly connected with the liquid inlet pipe joint 101, and the slow flow part 102 is beneficial to smoothly steering the fed liquid against the action of gravity; the liquid inlet channel 103 is smoothly connected with the slow flow part 102, the liquid inlet channel 103 extends downwards from the tail end of the slow flow part 102 along the gravity direction to form a long and narrow shape, and the long and narrow liquid inlet channel 103 also helps the main control unit of the floor washing machine to accurately control the liquid flow sent into the long and narrow channel 10 by the water pump. The elongated channel 10 is connected with the cavity 20, and the eta-shaped elongated channel 10 can prevent the electrolyzed solution in the cavity 20 from flowing backward to the liquid inlet pipe joint 101 under the action of external force because of the higher height difference between the liquid inlet pipe joint 101 and the highest point inlet of the cavity 20.

In this embodiment, a flow-slowing portion 102 is disposed at the top end of the liquid inlet channel 103, and the liquid inlet pipe joint 101 is disposed below the flow-slowing portion 102.
