[0026] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0027] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0028] A floor scrubber is specially used for cleaning the floor. It can spray cleaning fluid or water and detergent on the floor to wet and dissolve dirt. Floor scrubbers are usually equipped with rotating brushes or brush discs, which rotate when the machine moves, stirring and removing dirt from the floor through contact and friction with the floor. Floor scrubbers are equipped with water suction ports, which will draw the sewage, detergent and water on the floor into the water tank or liquid storage tank inside the machine when the brushing process is completed. After the water absorption is completed, the floor scrubber may also help the floor dry quickly by blowing air or using suction so that users can use the floor again as soon as possible.

[0029] Floor scrubbers can clean large areas of the floor quickly and thoroughly, and are more efficient than traditional manual cleaning methods. Using floor scrubbers to clean the floor does not require a large amount of manpower, reducing the burden of manual labor. Floor scrubbers are equipped with a scrubbing function that can thoroughly remove dirt and oil stains on the floor. Floor scrubbers can effectively control the amount of cleaning fluid used during the cleaning process, reducing the waste of water and detergents, and have the advantages of saving water and energy. Using floor scrubbers to clean the floor can reduce the risk of slips and falls, and improve workplace safety.

[0030] However, the self-cleaning function of the existing floor scrubbers is relatively simple, and they can only clean and dry the roller brushes, but cannot effectively deal with the dirt and bacteria remaining in the sewage collection system. These dirt and bacteria will become moldy and smelly after accumulating for a long time. For this reason, the utility model converts the clean water source of the floor scrubber into hydrogen peroxide with a sterilization function through an electrochemical reaction, and atomizes the hydrogen peroxide so that it can be fully diffused into the entire sewage collection system, thereby achieving effective sterilization of the sewage collection system and achieving the purpose of preventing mold and odor.

[0031] The technical solution of the utility model is described in detail below in conjunction with specific embodiments:

[0032] See also Figure 1-3 As shown, the floor scrubber provided by the embodiment of the utility model is a handheld cleaning device, which includes a main unit 100 and a floor brush assembly 200. The main unit 100 is provided with a handle 40, and the main unit 100 is hinged with the floor brush assembly 200. During use, the user holds the handle 40 and pushes the floor brush assembly 200 to move on the ground.

[0033] See also Figure 3 , 4 As shown, the floor brush assembly 200 includes a walking base 30, a roller brush 33 and a driving element 34. A roller brush chamber 31 is provided at the bottom of the walking base 30. The roller brush 33 is rotatably arranged in the roller brush chamber 31. The driving element 34 is used to drive the roller brush 33 to rotate. In a specific embodiment, the driving element 34 can be a motor, for example. Specifically, the walking base 30 can be provided with a plurality of walking wheels 32, for example, to reduce the pushing resistance and avoid damaging the ground. Part of the roller surface of the roller brush 33 is exposed below the walking base 30 and can contact the ground.

[0034] See also Figure 4 , 6As shown, the liquid supply system is used to spray the working liquid to the roller brush chamber 31, and the working liquid can be clean water or cleaning liquid. Specifically, the liquid supply system can include, for example, a clean water tank 10 and a second water pump 11, the water inlet of the second water pump 11 is connected to the clean water tank 10 through a water pipe, and the water outlet of the second water pump 11 is connected to the roller brush chamber 31 through a water pipe. In a further embodiment, a water distributor can be provided at the outlet of the water pipe to evenly distribute the clean water in the roller brush chamber 31. After the clean water enters the roller brush chamber 31, it can soak the roller brush 33, and as the roller brush 33 rotates, it moistens the ground and softens the dirt on the ground.

[0035] See also Figure 4 , 6 As shown, the sewage suction system is connected to the roller brush chamber 31 to suck the dirt in the roller brush chamber 31; specifically, the sewage suction system includes a suction channel 60, a sewage tank 20, a filter element 80 and a fan 70; one end of the suction channel 60 is connected to the sewage tank 20, and the other end is connected to the roller brush chamber 31; the air inlet side of the fan 70 is connected to the sewage tank 20, and the filter element 80 is arranged on the air inlet side of the fan 70. The sewage and debris on the ground and the roller brush 33 are sucked into the sewage tank 20 through the suction channel 60. In the sewage tank 20, the debris can be filtered by the filter element 80, so that larger particles or debris are blocked in the sewage tank 20, and these particles and debris are prevented from entering the fan 70, ensuring the cleanliness and effective operation of the fan 70. The utility model can quickly and effectively suck the sewage and debris on the ground into the sewage tank 20 through the combination of the suction channel 60 and the fan 70, so as to achieve efficient cleaning operations.

[0036] See also Figure 5 , 6 As shown, the sterilization system includes a chamber for containing and / or conveying clean water, and a hydrogen peroxide electrochemical reactor 92 and an atomizer 93, wherein the hydrogen peroxide electrochemical reactor 92 and the atomizer 93 are configured to be able to contact the clean water in the chamber.

[0037] In a specific embodiment, the cavity may include, for example, a sterilizing water tank 90, the hydrogen peroxide electrochemical reactor 92 is connected to the sterilizing water tank 90 through a pipeline, the atomizer 93 is connected to the hydrogen peroxide electrochemical reactor 92 through a pipeline, and the diffusion port is connected to the atomizer 93. In some other embodiments, the hydrogen peroxide electrochemical reactor 92 and the atomizer 93 may be directly installed in the sterilizing water tank 90. ​​The hydrogen peroxide electrochemical reactor 92 can convert the clean water in the sterilizing water tank 90 into hydrogen peroxide, the atomizer 93 can atomize the hydrogen peroxide, and the cavity is provided with a diffusion port 94, which is connected to the sewage suction system so that the atomized hydrogen peroxide can diffuse into the sewage suction system.

[0038] See also Figure 5 As shown, in an optional embodiment of the utility model, the diffusion port 94 is connected to one end of the suction channel 60 close to the roller brush chamber 31. The diffusion port 94 is arranged close to the roller brush chamber 31, so that the atomized hydrogen peroxide can fully contact with the roller brush 33. Although the sewage tank 20 and the filter element 80 are far away from the diffusion port 94, the hydrogen peroxide can be sucked into the sewage tank 20 by the fan 70, which can also ensure that the hydrogen peroxide is fully in contact with the sewage tank 20 and the filter element 80.

[0039] See also Figure 6 As shown, in an optional embodiment of the utility model, the cavity is connected to the clean water tank 10 through a pipeline. In this embodiment, the sterilization system uses the clean water source of the floor scrubber as the raw material for preparing hydrogen peroxide. The user only needs to add water to the clean water tank 10 to realize the corresponding function of the sterilization system, which simplifies the equipment structure and operation process.

[0040] See also Figure 5 , 6 As shown, in an optional embodiment of the utility model, the pipeline is provided with a first water pump 91. The first water pump 91 is used to transport the clean water in the clean water tank 10 to the sterilizing water tank 90. ​​It should be understood that the first water pump 91 is not necessary. For example, in some other embodiments, the clean water can also flow to the sterilizing water tank 90 by its own gravity.

[0041] See also Figure 4 As shown, the sewage tank 20, the filter element 80, the fan 70 and the clean water tank 10 are installed on the main machine 100; wherein the sewage tank 20, the filter element 80 and the clean water tank 10 are connected to the main machine 100 in a detachable manner. The detachable connection makes cleaning and maintenance more convenient; the user can easily remove the sewage tank 20, the filter element 80 and the clean water tank 10 for cleaning, thereby ensuring the cleanliness and hygiene of the machine. If it is necessary to repair or replace parts, the detachable connection makes the operation easier, and the maintenance personnel can easily remove the parts for maintenance or replacement without worrying about the damage that may be caused during the disassembly process; regular cleaning and maintenance can extend the service life of the floor scrubber. Through the detachable connection, the user can more easily perform these necessary maintenance work, thereby reducing the wear and failure risks of the machine caused by long-term use; the detachable design can also make cleaning and maintenance more convenient, which can reduce downtime, improve the working efficiency of the floor scrubber, and the user can complete the cleaning task more quickly.

[0042] See also Figure 5As shown, in an optional embodiment of the utility model, the first water pump 91, the sterilizing water tank 90, the hydrogen peroxide electrochemical reactor 92 and the atomizer 93 are installed on the walking base 30. In this embodiment, since the sterilizing system is arranged on the walking base 30, the atomized hydrogen peroxide can be diffused into the sewage suction system in the first time, so as to avoid the atomized hydrogen peroxide from condensing prematurely before entering the sewage suction system, thereby improving the diffusion effect. It should be understood that in some other embodiments, when the diffusion port 94 is arranged on the sewage tank 20, the sterilizing system can also be arranged on the host 100, which can also improve the diffusion effect of hydrogen peroxide.

[0043] See also Figure 6 As shown, in an optional embodiment of the present invention, a controller 300 is further included, and the driving element 34, the hydrogen peroxide electrochemical reactor 92, the atomizer 93 and the blower 70 are respectively electrically connected to the controller 300. A control signal input module 50 for controlling the start and stop of the hydrogen peroxide electrochemical reactor 92 and the atomizer 93 is also included, and the control signal input module 50 is electrically connected to the controller 300. In a specific embodiment, the control signal input module 50 can be, for example, a button installed on the handle portion 40.

[0044] By electrically connecting the driving element 34, the hydrogen peroxide electrochemical reactor 92, the atomizer 93, the fan 70 and the control signal input module 50 to the controller 300, comprehensive integrated control is achieved, which means that the entire floor scrubber system can be managed and adjusted by a single controller 300, which improves the convenience and consistency of operation. The controller 300 can accurately adjust the working state and parameters of the driving element 34, the hydrogen peroxide electrochemical reactor 92 and the atomizer 93 to meet the needs of different cleaning tasks. This precise control can improve the cleaning effect and is more energy-efficient and efficient. By electrically connecting the control signal input module 50 to the controller 300, the start and stop of the hydrogen peroxide electrochemical reactor 92 and the atomizer 93 can be controlled. Integrated control and precise adjustment capabilities help improve the stability and reliability of the floor scrubber system. The coordinated work between the various components of the system can ensure that the entire system can maintain a stable operating state under different working conditions, reduce failures and downtime, and improve work efficiency.

[0045] In summary, the utility model converts the clean water source of the floor scrubber into hydrogen peroxide with a sterilization function through an electrochemical reaction, and atomizes the hydrogen peroxide so that it can be fully diffused into the entire sewage collection system, thereby achieving effective sterilization of the sewage collection system and achieving the purpose of mildew and odor prevention; the diffusion port 94 is arranged close to the roller brush chamber 31, so that the atomized hydrogen peroxide is in full contact with the roller brush 33, and as for the sewage tank 20 and the filter element 80, although they are far away from the diffusion port 94, the hydrogen peroxide can be sucked into the sewage tank 20 by the fan 70, which can also ensure that the hydrogen peroxide and the filter element 80 are in full contact; the sterilization system uses the clean water source of the floor scrubber as the raw material for preparing hydrogen peroxide, and the user only needs to add water to the clean water tank 10 to realize the corresponding function of the sterilization system, which simplifies the equipment structure and operation process; the atomized hydrogen peroxide can be diffused into the sewage suction system as soon as possible, avoiding the premature condensation of the atomized hydrogen peroxide before entering the sewage suction system, thereby improving the diffusion effect.
