[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors, simultaneously drying wastewater and removing it from the site. It boasts advantages such as environmental friendliness, energy efficiency, and high performance, and the concept of replacing manual labor with machinery in cleaning has gained widespread acceptance. The structure of a floor scrubber mainly consists of a handle, the main body, and a roller brush connected in sequence. The main body has a spray structure corresponding to the roller brush, which sprays clean water onto the roller brush, allowing it to absorb water and effectively mop the floor. However, the disinfection and sterilization functions of existing floor scrubbers are not ideal and urgently need improvement. Utility Model Content
[0003] The purpose of this invention is to provide a floor scrubber with electrolytic water sterilization function, which effectively inhibits the odor of water in the clean water tank and improves the disinfection and sterilization performance.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a floor scrubber with electrolyzed water sterilization function, comprising a floor scrubber body and a clean water tank detachably installed on the floor scrubber body, the floor scrubber body being provided with a floor brush and a spray structure, the spray structure being aligned with the floor brush, the floor scrubber body being provided with an electrolyzed water module and a flow-through sterilization module, the clean water tank being provided with a water inlet and a water outlet, the water outlet of the clean water tank being connected to the spray structure in sequence through the electrolyzed water module and the flow-through sterilization module;
[0005] The water tank is equipped with a silver ion deodorizing device at the water outlet in its inner cavity, and an activated carbon adsorption device is detachably installed on the water tank.
[0006] By adopting the above technical solution, when the water tank is filled with water and has not been cleaned or replaced for a long time, the silver ion deodorizing device can effectively prevent bacteria from growing in the water tank and causing the water to smell bad. In addition, the activated carbon adsorption device can adsorb the heavy metals and chlorine contained in the raw water in the water tank, preventing the subsequent electrolysis of chlorine by the water electrolysis module from generating harmful substances such as hypochlorous acid that corrode the floor. The clean water discharged from the outlet of the water tank is electrolyzed by the water electrolysis module to produce electrolyzed water, which can improve the sterilization and disinfection ability of the ground. At the same time, this utility model adds a flow-through sterilization module downstream of the electrolysis module, which can effectively remove bacteria in the clean water sprayed onto the floor brush, further improving the sterilization and disinfection ability of this utility model. This utility model has the effect of effectively inhibiting the odor of the water in the water tank and improving the sterilization and disinfection performance.
[0007] A further feature of this invention is that the inner cavity of the clean water tank is provided with a water outlet valve that communicates with the water outlet.

[0008] By adopting the above technical solution, when the clean water tank is not installed on the main body of the floor scrubber, the spring pushes the valve core to block the water outlet, ensuring that the clean water in the clean water tank will not leak. When the clean water tank is installed on the main body of the floor scrubber, the top rod of the electrolytic water module pushes the valve core upward, so that the valve core is separated from the water outlet. At this time, the clean water in the clean water tank flows to the electrolytic water module through the water outlet.
[0009] A further feature of this invention is that the water electrolysis module includes a housing assembly, an anode electrode core and a cathode electrode plate disposed within the housing assembly, the housing assembly includes a water inlet top cover and a water outlet base, the water inlet top cover and the water outlet base are sealed together to form a hollow electrolysis chamber, the anode electrode core and the cathode electrode plate are disposed within the electrolysis chamber, and the top rod is integrally protruding from the water outlet base.
[0010] By adopting the above technical solution, the electrolytic water module can be used to electrolyze the clean water flowing out of the clean water tank, thereby achieving the purpose of rapid preparation of electrolyzed water.
[0011] A further feature of this invention is that a first sealing ring is provided between the water inlet top cover and the water outlet base.
[0012] By adopting the above technical solution, the first sealing ring can improve the water-proof performance between the joint between the water inlet top cover and the water outlet base.
[0013] A further feature of this invention is that the silver ion deodorizing device includes a silver ion mounting box that can be detachably installed outside the valve body. The silver ion mounting box has an annular inner cavity, which is filled with a plurality of silver ion particles. The silver ion mounting box has a plurality of through holes that communicate with the annular inner cavity in a radial direction.
[0014] By adopting the above technical solution, the water in the clean water tank can come into contact with the silver ion particles in the silver ion installation box through the through hole, thereby achieving disinfection and sterilization of the water source in the clean water tank.
[0015] A further feature of this invention is that the valve body has several buckles on its top, and the silver ion mounting box has a mounting hole in the middle. When the silver ion mounting box is fitted onto the valve body through the mounting hole, the buckles engage with the silver ion mounting box to prevent it from detaching.
[0016] By adopting the above technical solution, the silver ion mounting box is firmly installed on the valve body, preventing the silver ion mounting box from falling off due to shaking during the use of the floor scrubber.
[0017] A further feature of this invention is that the activated carbon adsorption device includes a cylindrical activated carbon mounting box and a plurality of activated carbon particles disposed within the activated carbon mounting box. A plurality of adsorption holes are provided through the outer wall of the activated carbon mounting box. The outer wall of the activated carbon mounting box is provided with external threads. A threaded hole is provided on the side wall of the water tank near the bottom. The external threads are threadedly engaged with the threaded hole.
[0018] By adopting the above technical solution, heavy metals and chlorine in the water tank are adsorbed by activated carbon particles through adsorption pores, and the threaded connection improves the ease of disassembly and replacement of the activated carbon adsorption device of this utility model.
[0019] A further feature of this invention is that the activated carbon mounting box is provided with a screwing part, and the water tank is integrally provided with a silicone ring at the opening end of the threaded hole corresponding to the screwing part. When the activated carbon mounting box is installed on the water tank through the threaded hole, the screwing part and the silicone ring are sealed together.
[0020] By adopting the above technical solution, the tight sealing effect between the silicone ring and the screw part can prevent water leakage between the activated carbon installation box and the threaded hole.
[0021] A further feature of this invention is that: the bottom of the clean water tank is provided with a water outlet sleeve, the water outlet is opened inside the water outlet sleeve, the main body of the floor scrubber is provided with a water receiving installation position corresponding to the water outlet sleeve, the water outlet sleeve and the water receiving installation position are inserted into each other, and a second sealing ring is provided outside the water outlet sleeve. When the water outlet sleeve is inserted into the water receiving installation position, the water outlet sleeve and the water receiving installation position are sealed together by the second sealing ring.
[0022] A further feature of this invention is that: a flip cover is hinged to the top of the clean water tank, a plug is provided on the side of the flip cover facing the clean water tank, and the water inlet is opened on the clean water tank corresponding to the plug, with the plug and the water inlet sealingly engaged.
[0023] By adopting the above technical solution, users can add water to the clean water tank through the water inlet. Before adding water, they only need to flip the cover to separate the plug from the water inlet. After adding water, the cover is reset so that the plug is pressed into the water inlet to seal it, thus sealing the water inlet. The operation is convenient and effectively improves the water tank's leak-proof performance.

[0025] This floor scrubber incorporates a floor brush, spray system, electrolyzed water module, and flow-through sterilization module within its main body. The water outlet of the clean water tank is connected to the spray system sequentially via the electrolyzed water module and the flow-through sterilization module. Additionally, the clean water tank is equipped with a silver ion deodorizing device and an activated carbon adsorption device. When the clean water tank is filled with water and has not been cleaned or replaced for an extended period, the silver ion deodorizing device effectively prevents bacterial growth and odor in the water. Furthermore, the activated carbon adsorption device removes heavy metals and chlorine from the raw water in the clean water tank. The adsorption process prevents harmful substances such as hypochlorous acid generated by the subsequent electrolysis of chlorine in the water electrolysis module from corroding the floor. The clean water discharged from the outlet of the clean water tank is electrolyzed by the water electrolysis module to produce electrolyzed water, which can improve the sterilization and disinfection ability of the floor. At the same time, this utility model adds a flow-through sterilization module downstream of the electrolyzed water module, which can effectively remove bacteria in the clean water sprayed onto the floor brush, further improving the sterilization and disinfection ability of this utility model. This utility model can effectively inhibit the odor of the water in the clean water tank and improve the sterilization and disinfection performance. Attached Figure Description
