Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and particularly relates to a cleaning equipment and a sterilization module. Background Art

[0002] With the progress of society and the development of technology and manufacturing processes, cleaning equipment such as floor sweeping robots and automatic floor scrubbers are increasingly widely used. These devices not only improve the cleaning efficiency but also enhance the hygiene and safety during the cleaning process by being equipped with a sterilization module.

[0003] However, there are some limitations in the selection and application of the sterilization module in the cleaning equipment on the market. For example, most floor scrubbers use a hypochlorous acid module. However, the hypochlorous acid module needs to rely on the chlorine element in water to electrolyze to produce hypochlorous acid, but the detected residual chlorine concentration in the device does not directly reflect the concentration of the effective disinfection component. In addition, the efficacy of the hypochlorous acid module will significantly decrease in water with a low total dissolved solids value, which results in poor performance in areas with good water quality. Therefore, it has certain limitations in use. At the same time, a single electrolysis product is difficult to meet various different application scenarios in the cleaning field. Summary of the Utility Model

[0004] The purpose of the present application is to provide a cleaning equipment and a sterilization module that can generate different electrolysis products and combinations according to different cleaning requirements.

[0005] To achieve the above purpose, on the one hand, the present application provides a cleaning equipment, which at least includes a body, a floor brush assembly, and a water supply module. The cleaning equipment is provided with a sterilization module, wherein the water supply module is in fluid communication with the sterilization module; the sterilization module includes a first electrolysis module and a second electrolysis module. The first electrolysis module includes a first electrolysis part, the second electrolysis module includes a second electrolysis part, the first electrolysis module and the second electrolysis module share a third electrolysis part. The first electrolysis part is adjacent to the third electrolysis part, the second electrolysis part is adjacent to the third electrolysis part, the polarities of the first electrolysis part and the second electrolysis part are the same, the polarity of the third electrolysis part is opposite to that of the first electrolysis part, and the electrolysis products of the first electrolysis module and the second electrolysis module are different.

[0006] To achieve the above object, on the other hand, the present application also provides a sterilization module. The sterilization module at least includes an electrolysis chamber and a first electrolysis module and a second electrolysis module located in the electrolysis chamber. The first electrolysis module includes a first electrolysis part, and the second electrolysis module includes a second electrolysis part. Wherein, the electrolysis chamber is in fluid communication with an external water supply module; the first electrolysis module and the second electrolysis module share a third electrolysis part, the third electrolysis part is located between the first electrolysis part and the second electrolysis part, the polarities of the first electrolysis part and the second electrolysis part are the same, the polarity of the third electrolysis part is opposite to that of the first electrolysis part, the electrolysis product of the first electrolysis module is ozone, and the electrolysis product of the second electrolysis module is hydrogen peroxide or hypochlorous acid.

[0007] It can be seen from this that in the technical solution provided by the present application, a sterilization module and a water supply module are provided inside the cleaning device. The water supply module is connected to the electrolysis chamber of the sterilization module, and it can supply the liquid in the water tank to the electrolysis chamber. The above-mentioned clean water can be used as the stock solution for the electrolysis reaction. In the electrolysis chamber, the first electrolysis module and the second electrolysis module that share the same electrolysis part (i.e., the third electrolysis part) can generate different cleaning substances through electrolysis. The first and second electrolysis modules have different component catalysts. By specially designing the components of the catalyst, during the electrolysis process, the first electrolysis part in the first electrolysis module can generate products such as ozone through electrolysis with the third electrolysis part through its specific catalyst, while the second electrolysis part in the second electrolysis module can generate cleaning products such as hydrogen peroxide or hypochlorous acid through electrolysis with the third electrolysis part through its specific catalyst. In the solution of the present application, the polarities of the first electrolysis part and the second electrolysis part are the same, and the polarity of the third electrolysis part is opposite to that of the first electrolysis part. By setting the third electrolysis part as the anode or the cathode, it is possible to achieve two anodes sharing one cathode or two cathodes sharing one anode, which can make the electrochemical reaction in the electrolysis chamber more concentrated and efficient. At the same time, the first and second electrolysis modules can cooperate with the shared third electrolysis part to generate different cleaning substances through different catalysts during the electrolysis process. With the above structure, the sterilization module can not only generate hydrogen peroxide or hypochlorous acid or ozone alone, but also generate hydrogen peroxide + ozone or hypochlorous acid + ozone or hydrogen peroxide + hypochlorous acid, etc. in combination. The sterilization module can adapt to different cleaning and disinfection requirements and can perform customized sterilization and deodorization treatments for different components and environments.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings. Relative position terms in space used in this application, such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end", etc., are for the purpose of facilitating description to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The relative position terms in space may be intended to include different orientations of the device in use or operation other than the orientation shown in the figures. For example, if the device in the figure is flipped, the unit described as being "below" or "beneath" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both the upper and lower orientations. The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptive terms used herein can be interpreted accordingly.

[0025] In addition, the terms "installed", "set up", "provided with", "connected", "slidably connected", "fixed", "socketed" should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] With the progress of society and the development of technology and manufacturing processes, cleaning devices such as floor-sweeping robots and automatic floor scrubbers are increasingly widely used. These devices not only improve the cleaning efficiency but also enhance the hygiene and safety during the cleaning process by equipping with disinfection modules.

[0027] However, there are some limitations in the selection and application of disinfection modules for cleaning devices on the market. Taking floor scrubbers as an example, most floor scrubbers use hypochlorous acid modules. However, the hypochlorous acid module needs to rely on the chlorine element in water to electrolyze to produce hypochlorous acid. However, the residual chlorine concentration detected by the device cannot directly reflect the concentration of the effective disinfection component because most of it may be ineffective components, which will lead to unstable disinfection effects of the hypochlorous acid module. In addition, the efficacy of the hypochlorous acid module will significantly decline in water with a low total dissolved solids (TDS) value, which results in poor performance in areas with good water quality. Therefore, it has certain limitations in use.

[0028] Some floor washers also use a separate hydrogen peroxide module or ozone module as a disinfection means. When the hydrogen peroxide module works, it can generate hydrogen peroxide. However, hydrogen peroxide is highly soluble in water and cannot exist in gaseous form, which causes the hydrogen peroxide module to be unable to disinfect parts that are difficult to reach by liquid, such as the recycling pipeline and recycling bucket inside the floor washer. It has almost no disinfection effect on the HEPA filter component in the floor washer. When the ozone module works, it can generate ozone. However, ozone is extremely difficult to dissolve in water and mainly exists in gaseous form. During the operation of the floor washer, most of the ozone will be sucked back into the recycling bucket and discharged, which makes it difficult for the ozone module to effectively disinfect components such as the roller brush.

[0029] Therefore, how to improve the electrolysis module so that it can not only comprehensively sterilize and deodorize components such as the roller brush, recycling bucket and pipeline in the cleaning equipment, but also be used to clean stubborn stains on the cleaned floor has become an urgent problem to be solved in this field.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0031] Please refer to Figures 1 to 9 , in an implementable embodiment, the cleaning equipment at least includes a body (not shown), a floor brush assembly 1 and a water supply module 2, and a sterilization module 3 is arranged inside the cleaning equipment. The sterilization module 3 can be arranged in the body or inside the floor brush assembly 1. The sterilization module 3 can adopt a detachable design for easy replacement or maintenance. In this application, the case where the sterilization module 3 is arranged inside the floor brush assembly 1 is taken as an example for illustration.

[0032] The water supply module 2 is in fluid communication with the sterilization module 3. The sterilization module 3 includes a first electrolysis module and a second electrolysis module. The electrolysis products of the first electrolysis module and the second electrolysis module are different, and the two electrolysis modules can work simultaneously. The first electrolysis module includes a first electrolysis part, the second electrolysis module includes a second electrolysis part, and the first electrolysis module and the second electrolysis module share a third electrolysis part. The first electrolysis part is adjacent to the third electrolysis part, the second electrolysis part is adjacent to the third electrolysis part, the polarities of the first electrolysis part and the second electrolysis part are the same, and the polarity of the third electrolysis part is opposite to that of the first electrolysis part and the second electrolysis part. Specifically, the electrolysis products of the first electrolysis module at least include ozone, and the electrolysis products of the second electrolysis module are hydrogen peroxide or hypochlorous acid or silver ions.

[0033] In this embodiment, a sterilization module 3 is detachably disposed inside the floor brush assembly 1. The water supply module 2 includes components such as a water pump, a water pipe, and a clean water tank. The water supply module 2 is in fluid communication with the sterilization module 3 through a pipeline. The water supply module 2 can use the water pump to transport the liquid in the clean water tank (including but not limited to pure water, tap water, a mixed liquid added with electrolytes, etc.) to the electrolysis chamber 311 of the sterilization module 3 as the electrolysis stock solution when the sterilization module 3 performs an electrochemical reaction.

[0034] It should be noted that the water supply module 2 can supply liquid to both the sterilization module 3 and components such as the roller brush and the water spraying plate in the cleaning device. In one embodiment, the sterilization module 3 can be connected in series in the water path of the water supply module 2. At this time, all the liquid supplied outward by the water supply module 2 will flow through the sterilization module 3. In another embodiment, the sterilization module 3 can also be connected in parallel in the water path of the water supply module 2. At this time, a valve can be used to control whether the liquid supplied outward by the water supply module 2 flows through the sterilization module 3.

[0035] In this embodiment, the polarities of the first electrolysis part and the second electrolysis part are anodes, and the polarity of the third electrolysis part is a cathode. For the convenience of description, the first electrolysis part is defined as the first anode electrolysis part 33, the second electrolysis part is defined as the second anode electrolysis part 34, and the third electrolysis part is defined as the third cathode electrolysis part 32. Inside the sterilization module 3, a first electrolysis module and a second electrolysis module with different electrolysis products are provided. The first electrolysis module and the second electrolysis module share the same third cathode electrolysis part 32. The first electrolysis module includes the first anode electrolysis part 33, and the second electrolysis module includes the second anode electrolysis part 34. The third cathode electrolysis part 32, the first anode electrolysis part 33, and the second anode electrolysis part 34 are all conductors, which can be made of metal materials such as stainless steel, titanium, nickel, and copper, or can also be made of metal oxides such as niobium oxide and titanium oxide. The third cathode electrolysis part 32, the first anode electrolysis part 33, and the second anode electrolysis part 34 can be made of the same electrode material, or can be made of different electrode materials according to the electrolytic substances they need to generate. For example, if the second anode electrolysis part 34 needs to generate hydrogen peroxide, then the second anode electrolysis part 34 can use titanium oxide as the electrode material to improve the hydrogen peroxide generation efficiency. If the first anode electrolysis part 33 needs to generate ozone, then the first anode electrolysis part 33 can use titanium-based nickel or pure titanium as the electrode material to improve the ozone generation efficiency.

[0036] The third cathode electrolysis section 32, the first anode electrolysis section 33, and the second anode electrolysis section 34 are all placed in the electrolysis chamber 311. The first anode electrolysis section 33 is adjacent to the third cathode electrolysis section 32, and the second anode electrolysis section 34 is adjacent to the third cathode electrolysis section 32. In other words, the first anode electrolysis section 33 is placed next to one side of the third cathode electrolysis section 32 to ensure that direct ion and electron exchange can occur between the first anode electrolysis section 33 and the third cathode electrolysis section 32, thereby promoting the electrolysis reaction. At the same time, the second anode electrolysis section 34 is also placed next to the other side of the third cathode electrolysis section 32 to ensure that direct ion and electron exchange can occur between the second anode electrolysis section 34 and the third cathode electrolysis section 32, thereby promoting the electrolysis reaction. The specific placement method of the third cathode electrolysis section 32, the first anode electrolysis section 33, and the second anode electrolysis section 34 will be described in detail later.

[0037] In practical applications, by adjusting the composition of the catalyst, specific oxidation and reduction reactions can occur on the anode and cathode, and then specific electrolysis products can be generated. In view of this, in this embodiment, the first electrolysis module and the second electrolysis module have catalysts with different compositions. The composition of the catalyst coated on the first anode electrolysis section 33 is different from the composition of the catalyst coated on the second anode electrolysis section 34, so that the first anode electrolysis section 33 and the second anode electrolysis section 34 can respectively produce different electrolysis products with the cathode to meet different cleaning and disinfection requirements.

[0038] In an implementable embodiment, the catalysts of the first electrolysis module and the second electrolysis module are metal coatings, and the above metal coatings are at least provided on the first anode electrolysis section 33 or the second anode electrolysis section 34. For example, the above metal coatings can be solidified on the surface of the first anode electrolysis section 33 and / or the second anode electrolysis section 34 through processes such as high-temperature sintering or electroplating.

[0039] It should be noted that the specific composition of the metal coating can be specifically designed according to the electrolysis products to be generated. For example, for electrolytic generation of ozone, a platinum single-atom catalyst or a titanium-based nickel and antimony co-doped tin dioxide catalyst can be used to make the metal coating; for electrolytic generation of hydrogen peroxide, a bismuth vanadate catalyst or a tin dioxide catalyst can be used to make the metal coating; for electrolytic generation of hypochlorous acid, an iridium oxide catalyst or a nickel iron oxide catalyst can be used to make the metal coating. The present application does not limit the specific composition of the metal coating. To make the first anode electrolysis section 33 and the second anode electrolysis section 34 respectively produce different electrolysis products, the first anode electrolysis section 33 and the second anode electrolysis section 34 have metal coatings with different compositions.

[0040] In an implementable embodiment, a catalyst is disposed on the surface of the first anode electrolysis unit 33 so that it can generate ozone, and another catalyst is disposed on the surface of the second anode electrolysis unit 34 so that it can generate hydrogen peroxide or hypochlorous acid or silver ions. In another implementable embodiment, a catalyst is disposed on the surface of the first anode electrolysis unit 33 so that it can generate hydrogen peroxide, and another catalyst is disposed on the surface of the second anode electrolysis unit 34 so that it can generate ozone or hypochlorous acid or silver ions. In another implementable embodiment, a catalyst is disposed on the surface of the first anode electrolysis unit 33 so that it can generate hypochlorous acid, and another catalyst is disposed on the surface of the second anode electrolysis unit 34 so that it can generate ozone or hydrogen peroxide or silver ions. In another implementable embodiment, a catalyst is disposed on the surface of the first anode electrolysis unit 33 so that it can generate silver ions, and another catalyst is disposed on the surface of the second anode electrolysis unit 34 so that it can generate ozone or hydrogen peroxide or hypochlorous acid.

[0041] In the solution provided by the present application, the first anode electrolysis unit 33 and the second anode electrolysis unit 34 share a third cathode electrolysis unit 32, which can make the electrochemical reaction in the electrolysis chamber 311 more concentrated and efficient. At the same time, the first anode electrolysis unit 33 and the second anode electrolysis unit 34 have catalysts with different compositions, so that they can independently generate hydrogen peroxide or ozone or hypochlorous acid or silver ions during electrolysis. With the above structure, the sterilization module 3 can not only generate hydrogen peroxide or hypochlorous acid or ozone or silver ions alone, but also generate combinations such as hydrogen peroxide + ozone or hypochlorous acid + ozone or hydrogen peroxide + hypochlorous acid or hydrogen peroxide + silver ions, etc., so that the cleaning device can perform customized sterilization and deodorization treatments for different components and environments.

[0042] In an implementable embodiment, the sterilization module 3 further includes a housing 31, and the housing 31 is divided into two parts: a power distribution room 312 and an electrolysis chamber 311. The first anode electrolysis unit 33, the second anode electrolysis unit 34, and the third cathode electrolysis unit 32 all have connection terminals connected to external cables. Specifically, the connection terminal 331 on the first anode electrolysis unit 33 extends into the power distribution room 312 and is connected to the first positive wire 41 in the external cable 4 in the power distribution room 312, that is, one end of the connection terminal 331 is electrically connected to the first anode electrolysis unit 33, and the other end of the connection terminal 331 is electrically connected to the first positive wire 41 in the power distribution room 312. In practical applications, the first anode electrolysis unit 33 and the connection terminal 331 can be integrally formed by processes such as casting, extrusion, and milling, or the connection terminal 331 can be made into a separate component and then fixed to the first anode electrolysis unit 33 by welding or riveting. The present application does not limit this.

[0043] Further, the terminal 341 on the second anodic electrolysis unit 34 extends into the power distribution room 312 and is connected to the second positive wire 42 in the cable 4 in the power distribution room 312. The terminal 321 on the third cathodic electrolysis unit 32 extends into the power distribution room 312 and is connected to the negative wire 43 in the cable 4 in the power distribution room 312. The terminals 331, 341, and 321 are arranged staggeredly from each other to facilitate the laying of the cable.

[0044] The cable 4 is connected to an external power source (electric energy provided by a storage battery in the cleaning device or the public power grid), and it can transmit the electric energy of the external power source to the first anodic electrolysis unit 33, the second anodic electrolysis unit 34, and the third cathodic electrolysis unit 32, thereby driving the electrolysis reaction. Further, the controller in the cleaning device can control the on / off states of the first positive wire 41, the second positive wire 42, and the negative wire 43, and thus control the electrolysis reaction of the first anodic electrolysis unit 33 and / or the second anodic electrolysis unit 34, and can control the reaction rate and product yield by adjusting the current and voltage.

[0045] For example, assume that the catalyst laid on the first anodic electrolysis unit 33 can cause the first anodic electrolysis unit 33 to electrolyze to produce ozone, and the catalyst laid on the second anodic electrolysis unit 34 can cause the second anodic electrolysis unit 34 to electrolyze to produce hydrogen peroxide. When the user uses the cleaning device to clean the ground, the user can select the hydrogen peroxide mode through the operation interface. At this time, the controller in the cleaning device can control the second electrolysis module to conduct, while the first electrolysis module does not conduct. In this way, the second electrolysis module will produce hydrogen peroxide, and the hydrogen peroxide will flow through the pipeline to the roller brush of the floor brush assembly 1, so that the cleaning device can use hydrogen peroxide to clean the ground. If the user finds that there are stubborn stains in the current cleaning area, or the cleaning device finds stubborn stains in the current cleaning area through the dirt detection device, the user can select the ozone mode or automatically switch to the ozone mode through the signal sent by the detection device. At this time, the controller in the cleaning device will control the first electrolysis module to conduct to generate ozone, and then form a cleaning liquid containing ozone. The above cleaning liquid can be sprayed out from the water spraying plate of the floor brush assembly 1, so as to achieve the cleaning of stubborn stains. Of course, when cleaning the ground, the cleaning device can also always maintain the simultaneous electrolysis to produce two electrolysis products, ozone and hydrogen peroxide.

[0046] It should be specifically noted that when the cleaning device is in the ozone mode, the controller can control the second positive electrode line 42 to continue to be energized, so that the second anode electrolysis part 34 continues to generate hydrogen peroxide. At this time, the sterilization module 3 generates hydrogen peroxide and ozone at the same time. Of course, the controller can also disconnect the second positive electrode line 42, so that the sterilization module 3 only generates ozone. In the present application, the controller in the cleaning device can adjust the electrolysis process by controlling the on-off states of the first positive electrode line 41, the second positive electrode line 42 and the negative electrode line 43, so as to control the sterilization module 3 to generate hydrogen peroxide or hypochlorous acid or ozone or silver ions alone, or generate hydrogen peroxide + ozone or hypochlorous acid + ozone or hydrogen peroxide + hypochlorous acid or hydrogen peroxide + silver ions, etc. in combination.

[0047] Optionally, for the convenience of installing various devices inside the housing 31, the housing 31 may be composed of an upper housing 313 and a lower housing 314. The lower housing 314 is configured in a box shape with an open top. The upper housing 313 is used to seal the top of the lower housing 314. The upper housing 313 and the lower housing 314 may be made of plastic materials and are structurally matched with each other to ensure that the upper housing 313 and the lower housing 314 can be accurately docked. When connecting the upper housing 313 and the lower housing 314, a welding process may be used to improve the firmness of the connection between the upper housing 313 and the lower housing 314. Specifically, a plastic or metal compatible with the material of the housing 31 may be used as the welding wire 315, and then the ultrasonic welding or laser welding process is used to fill the welding wire 315 on the joint surface between the upper housing 313 and the lower housing 314 to enhance the connection strength of the joint surface.

[0048] In an implementable embodiment, the electrolysis chamber 311 is provided with a water inlet 3111 and a water outlet 3112. The water inlet 3111 is communicated with the water inlet pipe in the water supply module 2, and at the same time, the water outlet 3112 is communicated with the water outlet pipe in the water supply module 2. The water outlet pipe of the water supply module 2 may be communicated with the water spraying plate and the roller brush in the floor brush assembly 1, or may be communicated with the self-cleaning pipeline in the cleaning device, and the present application does not limit this.

[0049] The water supply module 2 can use a water pump to transport the liquid in the water tank to the water inlet 3111 through the water inlet pipe, and then enter the electrolysis chamber 311 through the water inlet 3111. When the above liquid enters the electrolysis chamber 311, the third cathode electrolysis part 32, the first anode electrolysis part 33 and the second anode electrolysis part 34 will be immersed in the above liquid. If the first anode electrolysis part 33 and the third cathode electrolysis part 32 are energized, then under the action of the electric field between the first anode electrolysis part 33 and the third cathode electrolysis part 32, the liquid will be electrolyzed. Based on the composition of the catalyst laid on the surface of the first anode electrolysis part 33, specific electrolysis products will be generated at the first anode electrolysis part 33.

[0050] For example, assume that the catalyst laid on the first anode electrolysis unit 33 can cause the first anode electrolysis unit 33 to electrolyze and generate ozone. Then, after the first anode electrolysis unit 33 and the third cathode electrolysis unit 32 are powered on, ozone gas microbubbles will be generated at the first anode electrolysis unit 33. After the ozone gas microbubbles are mixed into the liquid in the electrolysis chamber 311, they can enter the water outlet pipe of the water supply module 2 through the water outlet 3112, and then flow to the water spray plate, the rotary brush, etc. through various pipelines in the cleaning device. Further, an ozone collection module is also provided in the cleaning device. A negative pressure motor is provided inside the ozone collection module, and the negative pressure motor can form a suction air flow. The ozone collection module is communicated with the water outlet pipe of the water supply module 2. When the ozone collection module works, the suction air flow formed by the negative pressure motor can collect the ozone escaping from the liquid, and then transport the above-mentioned ozone to the HEPA component, the recycling bucket, and various pipelines in the cleaning device, so as to sterilize and deodorize the above-mentioned components.

[0051] Further, the power distribution room 312 is filled with a sealant 3121, and the above-mentioned sealant 3121 is used to prevent the liquid in the electrolysis chamber 311 from entering the power distribution room 312. Specifically, when the terminal 331 on the first anode electrolysis unit 33 is connected to the first positive wire 41 in the cable 4, the terminal 341 on the second anode electrolysis unit 34 is connected to the second positive wire 42 in the cable 4, and the terminal 321 on the third cathode electrolysis unit 32 is connected to the negative wire 43 in the cable 4, the technician can fill epoxy resin sealant in the power distribution room 312. The sealant 3121 can effectively prevent moisture and humidity from entering the power distribution room 312, protect the electrical components and wiring inside the power distribution room 312 from moisture erosion, thereby avoiding short circuits. At the same time, the sealant 3121 can also fix the cable and the electrolysis unit, prevent them from shifting due to mechanical vibration or external force, and provide insulation protection to prevent accidental contact between different conductors.

[0052] In practical applications, as the electrolysis time increases, the scale generated during the electrolysis process will gradually cover the electrolysis unit, which will lead to a decrease in electrolysis efficiency until the sterilization module 3 approaches failure. To solve the above problems, in a feasible implementation manner, the sterilization module 3 is designed as a detachable structure, which is detachably connected inside the cleaning device. When the performance of the sterilization module 3 drops to the limit of use or cannot meet the working requirements, the user can easily remove the worn-out sterilization module 3 and replace it with a new and intact sterilization module 3.

[0053] Optionally, an ultrasonic component is provided on the side or bottom of the electrolysis chamber 311. This ultrasonic component is used to convert electrical energy into mechanical vibrations in the form of ultrasonic waves and transmit the mechanical vibrations into the electrolyte. The vibration energy generated by the ultrasonic waves can destroy the scale structure and cause it to fall off from the surface of the electrolysis part, thereby reducing the accumulation of scale. By regularly using the ultrasonic component to remove scale, the cleanliness of the electrolysis part can be maintained, the efficiency of the electrolysis process can be sustained, and ultimately the service life of the sterilization module 3 can be extended.

[0054] It should be noted that in the above-described embodiment, the sterilization module 3 is described as being provided inside the floor scrubbing component 1. However, in actual applications, the sterilization module 3 can also be provided in a cleaning base station, the body of a floor washer, etc., as long as it is ensured that the sterilization module 3 and the water supply pipeline inside or outside the cleaning device can form a circulating water path.

[0055] Next, the placement methods and specific structures of the third cathode electrolysis part 32, the first anode electrolysis part 33, and the second anode electrolysis part 34 will be described.

[0056] Embodiment 1

[0057] As Figure 2 , Figure 5 and Figure 6 shown, in this embodiment, the first electrolysis module includes the first anode electrolysis part 33, the second electrolysis module includes the second anode electrolysis part 34, and the two electrolysis modules share the same third cathode electrolysis part 32. The third cathode electrolysis part 32, the first anode electrolysis part 33, and the second anode electrolysis part 34 are all plate-like structures and have one or more hollow holes. Taking the Figure 5 shown perspective as a reference, in the vertical direction, the first anode electrolysis part 33, the third cathode electrolysis part 32, and the second anode electrolysis part 34 are stacked and spaced from top to bottom in sequence, and a first insulating frame 35 is provided between the first anode electrolysis part 33 and the third cathode electrolysis part 32, and a second insulating frame 36 is provided between the third cathode electrolysis part 32 and the second anode electrolysis part 34. The first insulating frame 35 and the second insulating frame 36, as support frames, can keep the first anode electrolysis part 33 and the second anode electrolysis part 34 at a definite distance from the third cathode electrolysis part 32 respectively. By adjusting the thicknesses of the first insulating frame 35 and the second insulating frame 36, the distances between the first anode electrolysis part 33, the second anode electrolysis part 34 and the third cathode electrolysis part 32 can be adjusted. The change in the distance between the positive and negative electrode electrolysis parts can adjust the electrolysis efficiency, that is, adjust the mass concentration of the electrolysis products of the sterilization module to ensure the electrolysis effect.

[0058] The third cathode electrolysis section 32, the first anode electrolysis section 33, and the second anode electrolysis section 34 are all configured in a flat plate shape, which helps to provide a larger electrolysis reaction surface area, thereby improving the electrolysis efficiency. At the same time, there are one or more hollow holes on the third cathode electrolysis section 32, the first anode electrolysis section 33, and the second anode electrolysis section 34. The above-mentioned hollow hole structure allows the bubbles generated during electrolysis to pass through quickly, and promotes the flow and diffusion of the electrolyte, thereby improving the electrolysis performance. The first insulating frame 35 and the second insulating frame 36 can be made of insulating materials such as plastic and epoxy resin, which can prevent direct contact between the electrodes, avoid short circuits, and ensure that the current only flows through the reaction path in the electrolyte.

[0059] It should be noted that the respective hollow holes on the third cathode electrolysis section 32, the first anode electrolysis section 33, and the second anode electrolysis section 34 can be evenly distributed on the electrolysis section or randomly distributed on the electrolysis section. The number of holes on each electrolysis section can be the same or different, and the present application does not limit this. The sum of the areas of all the hollow holes accounts for 50% or more of the area of the plate-like structure, but does not exceed 70% of the area of the plate-like structure, so as to balance the surface area of the electrolysis reaction of the plate-like structure and the efficiency of the electrolysis products passing through the plate-like structure quickly with the bubbles and flowing out with the liquid.

[0060] Optionally, at least one upper support pillar 3113 and at least one lower support pillar 3114 are provided inside the electrolysis chamber 311. Among them, the upper support pillar 3113 extends downward from the top of the housing 31 (i.e., the upper housing 313), and the lower support pillar 3114 extends upward from the bottom of the housing 31 (i.e., the bottom surface of the lower housing 314). The extension distance of the upper support pillar 3113 is related to the installation position of the first anode electrolysis section 33 in the electrolysis chamber 311, and it is necessary to ensure that the upper support pillar 3113 can abut against the first anode electrolysis section 33. Correspondingly, the extension distance of the lower support pillar 3114 is related to the installation position of the second anode electrolysis section 34 in the electrolysis chamber 311, and it is necessary to ensure that the lower support pillar 3114 can abut against the second anode electrolysis section 34. The upper support pillar 3113 and the lower support pillar 3114 can provide physical support for the first anode electrolysis section 33 and the second anode electrolysis section 34, which helps to accurately position the electrolysis section and ensure the correct positions of the first anode electrolysis section 33 and the second anode electrolysis section 34 in the electrolysis chamber 311, thereby ensuring the effectiveness of the electrolysis process. At the same time, the presence of the upper support pillar 3113 and the lower support pillar 3114 can also leave a gap between the first anode electrolysis section 33 and the second anode electrolysis section 34 and the housing 31. This gap allows the electrolyte to flow more freely between the electrolysis sections, so that the reactants can reach the electrode surface more effectively, and the electrolysis products can also be more easily removed from the electrode surface, thereby improving the electrolysis efficiency.

[0061] The catalyst of the first electrolysis module is a metal coating disposed on the first anode electrolysis part 33, and the catalyst of the second electrolysis module is a metal coating disposed on the second anode electrolysis part 34. The compositions of the metal coatings serving as catalysts in the first electrolysis module and the second electrolysis module are different, so as to respectively cooperate with the shared cathode to produce different electrolysis products.

[0062] Optionally, the distance between the first anode electrolysis part 33 and the third cathode electrolysis part 32 is greater than or equal to 1 mm but less than or equal to 2 mm. Preferably, the distance between the first anode electrolysis part 33 and the third cathode electrolysis part 32 is greater than or equal to 1 mm but less than 1.5 mm.

[0063] Embodiment 2

[0064] As Figures 2 to 4 shown, in this embodiment, the third cathode electrolysis part 32, the first anode electrolysis part 33, and the second anode electrolysis part 34 are all plate-like structures and have one or more hollow holes. The sum of the areas of all the hollow holes accounts for 50% or more of the area of the plate-like structure, but does not exceed 70% of the area of the plate-like structure. Taking Figure 3 the shown perspective as a reference, in the vertical direction, the first anode electrolysis part 33, the third cathode electrolysis part 32, the first carrier part 37, and the second anode electrolysis part 34 are stacked in sequence from top to bottom. And a first insulating frame 35 is provided between the first anode electrolysis part 33 and the third cathode electrolysis part 32, and a second insulating frame 36 is provided between the first carrier part 37 and the second anode electrolysis part 34.

[0065] The distance between the first anode electrolysis part 33 and the third cathode electrolysis part 32 is greater than 1 mm but less than 2 mm. Preferably, the distance between the first anode electrolysis part 33 and the third cathode electrolysis part 32 is greater than 1 mm but less than 1.5 mm.

[0066] The main difference between this embodiment and Embodiment 1 is that the catalyst of the second electrolysis module of the sterilization module 3 includes a catalyst carrier part. In this embodiment, the catalyst carrier part is defined as the first carrier part 37. In this embodiment, the first carrier part 37 is disposed between the second anode electrolysis part 34 and the third cathode electrolysis part 32. The first carrier part 37 includes a porous matrix, and a catalyst with a specific composition is doped in the porous matrix. The structure of the first carrier part 37 is also a plate-like structure. The first carrier part 37 is placed close to the third cathode electrolysis part 32, and the first carrier part 37 is disposed on the outer surface of the third cathode electrolysis part 32 facing the second anode electrolysis part 34, that is, the first carrier part 37 is disposed between the third cathode electrolysis part 32 and the second anode electrolysis part 34.

[0067] The porous matrix structure of the first carrier part 37 can facilitate current collection and gas diffusion, improve the reaction rate in the bubble aggregation region. At the same time, the porous structure can also significantly increase the reaction specific surface area of the catalyst, provide more attachment points for the active components, and thus improve the catalytic efficiency. In practical applications, the porous matrix structure can be made of alumina, metal foam, metal organic compounds, etc. The catalyst can be made into a nanostructure and then doped into the above-mentioned porous matrix to improve the stability of the overall structure of the catalyst.

[0068] Optionally, the thickness of the first carrier part 37 can be set between 3 mm and 6 mm. It should be particularly noted that in this embodiment, the second anode electrolysis part 34 and the first carrier part 37 can have the same catalyst composition. By specially designing the composition of the catalyst, it can be ensured that the second anode electrolysis part 34 and the first carrier part 37 are used to generate hydrogen peroxide. When the first carrier part 37 exists, if the third cathode electrolysis part 32 and the second anode electrolysis part 34 are energized, the sterilization module 3 can generate 3 mg to 5 mg of hydrogen peroxide per second. Compared with the solution without the first carrier part 37, the production efficiency of hydrogen peroxide in this embodiment is higher.

[0069] Embodiment Three

[0070] The main difference between this embodiment and Embodiment Two is that the sterilization module 3 further includes a catalyst provided in the third cathode electrolysis part 32 and having a second carrier part (not shown). The second carrier part is placed close to the third cathode electrolysis part 32, and the second carrier part is provided between the third cathode electrolysis part 32 and the first anode electrolysis part 33. In other words, in this embodiment, the catalyst includes both the first carrier part 37 and the second carrier part. The first carrier part 37 is provided on the side of the third cathode electrolysis part 32 facing the second anode electrolysis part 34, and the second carrier part is provided on the side of the third cathode electrolysis part 32 facing the first anode electrolysis part 33, that is, the first carrier part 37 and the second carrier part are respectively located on both sides of the third cathode electrolysis part 32.

[0071] The structure of the second carrier part is similar to that of the first carrier part 37. The second carrier part also includes a porous matrix and a catalyst doped in the porous matrix. It should be noted that the catalyst composition in the second carrier part is different from that in the first carrier part 37. Specifically, the catalyst composition contained in the first carrier part 37 is the same as the catalyst composition laid on the second anode electrolysis part 34, and the catalyst composition contained in the second carrier part is the same as the catalyst composition laid on the first anode electrolysis part 33. Of course, in the case where the first carrier part 37 and the second carrier part exist, the surfaces of the first anode electrolysis part 33 and the second anode electrolysis part 34 may no longer be laid with catalysts.

[0072] Embodiment Four

[0073] As shown Figures 7 to 9 in FIG. 3, in the present embodiment, the third cathode electrolysis part 32 includes a strip-shaped third main body part 324 and two rows of third ribs extending from both sides of the third main body part 324 in opposite directions. For the convenience of description, the ribs on one side of the two rows of third ribs are defined as the first cathode ribs 322, and the ribs on the other side are defined as the second cathode ribs 323. The first cathode ribs 322 and the second cathode ribs 323 are alternately arranged on both sides of the third main body part 324, so that the third cathode electrolysis part 32 has a fishbone-like structure.

[0074] The first anode electrolysis part 33 includes a first main body part 333 and a plurality of first ribs 332 extending from one side of the first main body part 333. The first anode ribs 332 are arranged on one side of the first main body part 333, so that the first anode electrolysis part 33 has a comb-like tooth structure. The second anode electrolysis part 34 includes a second main body part 343 and a plurality of second ribs 342 extending from one side of the second main body part 343. The second ribs 342 are arranged on one side of the second main body part 343, so that the second anode electrolysis part 34 has a comb-like tooth structure.

[0075] The third cathode electrolysis part 32, the first anode electrolysis part 33 and the second anode electrolysis part 34 are configured such that: the first anode electrolysis part 33 is located on the first side of the third main body part 324, the second anode electrolysis part 34 is located on the second side of the third main body part 324, and after the third cathode electrolysis part 32, the first anode electrolysis part 33 and the second anode electrolysis part 34 are assembled together, there is a first rib 332 of the first anode electrolysis part 33 between two adjacent third ribs on the first side of the third main body part 324, and there is a second rib 342 of the second anode electrolysis part 34 between two adjacent third ribs on the second side of the third main body part 324. In other words, the first main body part 333 is parallel to the third main body part 324, and at the same time, the second main body part 343 is also parallel to the third main body part 324. There is a first rib 332 between two adjacent first cathode ribs 322, and there is a second rib 342 between two adjacent second cathode ribs 323, that is, the first cathode ribs 322 and the first ribs 332 are alternately arranged one by one, and the second cathode ribs 323 and the second ribs 342 are alternately arranged one by one. The above structure can increase the total reaction surface area of the third cathode electrolysis part 32, the first anode electrolysis part 33 and the second anode electrolysis part 34, and can form a plurality of small electrolysis gaps between the electrolysis parts, thereby improving the electrolysis efficiency and promoting the release of electrolysis products. At the same time, the fishbone-like arrangement helps the electrolyte to flow between the respective electrolysis parts, thereby reducing bubble aggregation and improving the mass transfer effect.

[0076] Optionally, multiple insulating grooves 3141 are provided at the bottom of the housing 31 (i.e., the lower housing 314). The comb-shaped ribs on the third cathode electrolysis part 32 (including the first cathode rib 322 and the second cathode rib 323), the comb-shaped first rib 332 on the first anode electrolysis part 33, and the comb-shaped second rib 342 on the second anode electrolysis part 34 are respectively placed in the respective insulating grooves 3141. The insulating grooves 3141 can provide support for each metal strip, keep each metal strip at an appropriate distance, and reduce the risk of short circuit caused by accidental contact between electrolysis parts.

[0077] Optionally, as Figure 8 shown, in the vertical direction, the heights of the third cathode electrolysis part 32, the first anode electrolysis part 33, and the second anode electrolysis part 34 are all less than the height of the electrolysis chamber 311. The above structure can ensure that there is a gap between the electrolysis part and the inner wall of the electrolysis chamber 311, thereby promoting the flow of the electrolyte in the electrolysis chamber 311 and improving the contact efficiency between the electrolyte and the electrolysis part.

[0078] Optionally, in the vertical direction, the height of the water inlet 3111 is less than the height of the water outlet 3112, and the first anode electrolysis part 33 is higher than the height of the water inlet 3111 but less than the height of the water outlet 3112. For example, the water inlet 3111 can be provided on the lower housing 314, and the water outlet 3112 can be provided on the upper housing 313. The lower water inlet design helps to promote the flow of the electrolyte in the electrolysis chamber 311 by gravity, thereby improving the contact efficiency between the electrolyte and the electrolysis part. At the same time, the gas generated during the electrolysis process often rises, so the higher water outlet design can more effectively collect these gases and prevent the gases from accumulating inside the electrolysis chamber 311.

[0079] In daily life, silver ions are widely used in the water treatment field due to their antibacterial properties. To improve the antibacterial effect of the sewage bucket in the cleaning device, it can be considered to use silver ions to inhibit bacteria in the sewage bucket.

[0080] In an achievable implementation manner, the metal plating catalyst of the first anode electrolysis part 33 or the second anode electrolysis part 34 contains metallic silver. When the first anode electrolysis part 33 and the second anode electrolysis part 34 are energized, in addition to generating hydrogen peroxide or ozone or hypochlorous acid, the first anode electrolysis part 33 and the second anode electrolysis part 34 will also electrolyze to generate silver ions, and the above silver ions can be mixed in the liquid. As the cleaning device works, the liquid mixed with silver ions will enter the sewage bucket, so that the sewage bucket has a long-term antibacterial effect.

[0081] In an achievable implementation, a fourth anodic electrolysis part can be added to the sterilization module 3, that is, there are three anodic electrolysis parts in the sterilization module 3. The fourth anodic electrolysis part is connected to the positive wire of the cable 4, and the catalyst on the fourth anodic electrolysis part contains metallic silver component. Of course, the fourth anodic electrolysis part can also be made of metallic silver. When the cleaning device is performing cleaning work, the first anodic electrolysis part 33 or / and the second anodic electrolysis part 34 of the sterilization module 3 is / are electrified, so as to electrolytically generate hydrogen peroxide or ozone or hypochlorous acid for rapid sterilization. When the cleaning device finishes the cleaning work, it can perform self-cleaning. At this time, the fourth anodic electrolysis part is electrified, and it can electrolytically generate silver ions. The silver ions are mixed in the liquid and finally remain in the sewage bucket, so that the sewage bucket has a long-term antibacterial effect.

[0082] In an achievable implementation, a silver ion slow-release box can be installed in the sewage tank of the cleaning device. When the cleaning device is performing cleaning work, the first anodic electrolysis part 33 or / and the second anodic electrolysis part 34 of the sterilization module 3 is / are electrified, so as to electrolytically generate hydrogen peroxide or ozone or hypochlorous acid for rapid sterilization. When the cleaning device finishes the cleaning work, the silver ion slow-release box in the sewage bucket is activated and releases silver ions, so that the sewage bucket has a long-term antibacterial effect.

[0083] Based on the same concept, the present application also provides a sterilization module. The sterilization module 3 at least includes an electrolysis chamber 311, a third cathodic electrolysis part 32, a first anodic electrolysis part 33 and a second anodic electrolysis part 34. Among them, the electrolysis chamber 311 is in fluid communication with an external water supply module, so that the water supply module can supply electrolytic reaction stock solution to the electrolysis chamber 311.

[0084] The third cathodic electrolysis part 32, the first anodic electrolysis part 33 and the second anodic electrolysis part 34 are all conductors, and they can be made of metal materials such as stainless steel, titanium, nickel, copper, etc., or can also be made of metal oxides such as niobium oxide, titanium oxide, etc.

[0085] The third cathodic electrolysis part 32, the first anodic electrolysis part 33 and the second anodic electrolysis part 34 are all placed in the electrolysis chamber 311, and the first anodic electrolysis part 33 is adjacent to the third cathodic electrolysis part 32, and the second anodic electrolysis part 34 is adjacent to the third cathodic electrolysis part 32. The first anodic electrolysis part 33 and the second anodic electrolysis part 34 have catalysts with different compositions, that is, the composition of the catalyst laid on the first anodic electrolysis part 33 is different from the composition of the catalyst laid on the second anodic electrolysis part 34, so that the first anodic electrolysis part 33 and the second anodic electrolysis part 34 can respectively generate different electrolytic products to meet different cleaning and disinfection requirements.

[0086] In an implementable embodiment, a catalyst is coated on the surface of the first anode electrolysis unit 33 so that it can generate ozone, and another catalyst is coated on the surface of the second anode electrolysis unit 34 so that it can generate hydrogen peroxide or hypochlorous acid or silver ions.

[0087] Optionally, a catalyst is coated on the surface of the first anode electrolysis unit 33 so that it can generate hydrogen peroxide, and another catalyst is coated on the surface of the second anode electrolysis unit 34 so that it can generate ozone or hypochlorous acid or silver ions. In another implementable embodiment, a catalyst is coated on the surface of the first anode electrolysis unit 33 so that it can generate hypochlorous acid, and another catalyst is coated on the surface of the second anode electrolysis unit 34 so that it can generate hydrogen peroxide or silver ions or ozone.

[0088] Regarding the detailed structure of the sterilization module 3, reference can be made to the content in the above embodiments, which will not be elaborated here.

[0089] Based on the same concept, the present application also provides a cleaning device, which at least includes a clean water tank and a sterilization module 3. Among them, the clean water tank is in fluid communication with the sterilization module 3 and is used to supply the electrolysis reaction stock solution to the electrolysis chamber 311 in the sterilization module 3.

[0090] The sterilization module 3 at least includes a third cathode electrolysis unit 32, a first anode electrolysis unit 33 and a second anode electrolysis unit 34. The third cathode electrolysis unit 32, the first anode electrolysis unit 33 and the second anode electrolysis unit 34 are all conductors, which can be made of metal materials such as stainless steel, titanium, nickel, copper, etc., or can also be made of metal oxides such as niobium oxide and titanium oxide.

[0091] The third cathode electrolysis unit 32, the first anode electrolysis unit 33 and the second anode electrolysis unit 34 are all placed in the electrolysis chamber 311, and the first anode electrolysis unit 33 is adjacent to the third cathode electrolysis unit 32, and the second anode electrolysis unit 34 is adjacent to the third cathode electrolysis unit 32. The first anode electrolysis unit 33 and the second anode electrolysis unit 34 have catalysts with different compositions, that is, the composition of the catalyst coated on the first anode electrolysis unit 33 is different from the composition of the catalyst coated on the second anode electrolysis unit 34, so that the first anode electrolysis unit 33 and the second anode electrolysis unit 34 can respectively generate different electrolysis products to meet different cleaning and disinfection requirements.

[0092] In an implementable embodiment, a catalyst is coated on the surface of the first anode electrolysis unit 33 so that it can generate ozone, and another catalyst is coated on the surface of the second anode electrolysis unit 34 so that it can generate hydrogen peroxide or hypochlorous acid or silver ions.

[0093] Optionally, a catalyst is disposed on the surface of the first anode electrolysis unit 33 to generate hydrogen peroxide, and another catalyst is disposed on the surface of the second anode electrolysis unit 34 to generate ozone or hypochlorous acid or silver ions. In another implementable embodiment, a catalyst is disposed on the surface of the first anode electrolysis unit 33 to generate hypochlorous acid, and another catalyst is disposed on the surface of the second anode electrolysis unit 34 to generate hydrogen peroxide or silver ions or ozone.

[0094] In the above several embodiments, the polarities of the first electrolysis unit and the second electrolysis unit are anodes, and the polarity of the third electrolysis unit is a cathode. However, in other embodiments, the polarities of the first electrolysis unit and the second electrolysis unit can be cathodes, and the polarity of the third electrolysis unit can be an anode. For the convenience of understanding the following text, the first electrolysis unit is defined as the first cathode electrolysis unit 51, the second electrolysis unit is defined as the second cathode electrolysis unit 52, and the third electrolysis unit is defined as the third anode electrolysis unit 53.

[0095] In one embodiment, the cleaning device includes a body (not shown), a floor brush assembly 1, and a water supply module 2. A sterilization module 3 is disposed inside the cleaning device, and the water supply module 2 is in fluid communication with the sterilization module 3. The sterilization module 3 includes a first electrolysis module and a second electrolysis module. The electrolysis products of the first electrolysis module and the second electrolysis module are different, and the two electrolysis modules can work simultaneously to generate different electrolysis products. The first electrolysis module includes a first cathode electrolysis unit 51, the second electrolysis module includes a second cathode electrolysis unit 52, and the first electrolysis module and the second electrolysis module share a third anode electrolysis unit 53. The first cathode electrolysis unit 51 is adjacent to the third anode electrolysis unit 53, and the second cathode electrolysis unit 52 is adjacent to the third anode electrolysis unit 53. Specifically, the electrolysis products of the first electrolysis module at least include ozone, and the electrolysis products of the second electrolysis module are hydrogen peroxide. The sterilization module 3 has a water inlet 3111 and a water outlet 3112, and the water outlet 3112 is located above the water inlet 3111.

[0096] The first electrolysis module includes a first insulating frame 35 clamped between a first cathode electrolysis part 51 and a third anode electrolysis part 53. The second electrolysis module further includes a catalyst carrier part 54 clamped between a second cathode electrolysis part 52 and the third anode electrolysis part 53, and a second insulating frame 36. The catalyst carrier part 54 is arranged on the outer surface of the second cathode electrolysis part 52 facing the third anode electrolysis part 53. The second insulating frame 36 includes two relatively arranged first side frames 361 and a second side frame 362 connected between the two first side frames 361. The second insulating frame 36 is provided with a plurality of partitions 363 parallel to the second side frame 362 and spaced from each other and connected between the two first side frames 361. Each partition 363 is provided with a notch at the connection with the first side frame 361, and the positions where the adjacent two partitions 363 are provided with notches are located at the connections of different first side frames 361, so as to form a multi-segment and connected reciprocally bent S-shaped water flow channel. The second insulating frame 36 is clamped between the third anode electrolysis part 53 and the catalyst carrier part 54, that is, the upper and lower ends of each partition 363 are abutted against the surfaces of the catalyst carrier part 54 and the third anode electrolysis part 53, so that the liquid entering from the water inlet 3111 of the sterilization module 3 flows between the third anode electrolysis part 53 and the catalyst carrier part 54 along the S-shaped flow channel, thereby increasing the flow path length of the liquid and enabling it to fully carry out the electrolysis reaction during electrolysis.

[0097] The first cathode electrolysis part 51, the second cathode electrolysis part 52 and the third anode electrolysis part 53 are plate-like structures with a plurality of hollow holes. The first cathode electrolysis part 51, the third anode electrolysis part 53 and the second cathode electrolysis part 52 are arranged at intervals in sequence and are relatively arranged. The distance between the first cathode electrolysis part 51 and the third anode electrolysis part 53 is less than the distance between the second cathode electrolysis part 52 and the third anode electrolysis part 53. The sum of the areas of all the hollow holes accounts for 50% or more of the area of the plate-like structure, but does not exceed 70% of the area of the plate-like structure. The distance d1 between the first cathode electrolysis part 51 and the third anode electrolysis part 53 is greater than or equal to 1 mm, but less than or equal to 2 mm. Preferably, the distance d1 between the first cathode electrolysis part 51 and the third anode electrolysis part 53 is greater than or equal to 1 mm, but less than 1.5 mm. The range of the distance d2 between the second cathode electrolysis part 52 and the third anode electrolysis part 53 is 4 mm - 10 mm, and the preferred range is between 5 mm - 8 mm. During the cleaning process, the electrolysis product ozone will volatilize into the external air. By controlling the distance between the positive and negative electrolysis parts (i.e., the first cathode electrolysis part 51 and the third anode electrolysis part 53) in the first electrolysis module, it can be ensured that the mass concentration of ozone generated by electrolysis can complete the cleaning of dirt and disinfection and sterilization, while the concentration of ozone after volatilization is lower than 0.02 mL / m 3 , so as to ensure that the special smell of ozone will not stimulate the user's sense of smell.

[0098] The sterilization module 3 further includes a housing 31, which includes an upper housing 313 and a lower housing 314. Ribs are convexly provided on the inner surfaces of the upper housing 313 and the lower housing 314. The surface of the first cathode electrolysis part 51 abuts against the ribs of the upper housing 313 to form an S-shaped bending flow channel, and the surface of the second cathode electrolysis part 52 abuts against the ribs of the lower housing 314 to form another S-shaped bending flow channel, thereby increasing the length of the liquid electrolysis reaction path and ensuring sufficient electrolysis. The catalyst carrier 54 is carbon felt, and the range of the thickness d3 of the carbon felt is 3 mm - 6 mm.

[0099] Regarding the specific structure of the sterilization module 3, reference can be made to the content in the above embodiments, which will not be elaborated here. The specific type of the cleaning device can be a floor washer, a fabric cleaning machine, a sweeping robot, a window cleaning robot, etc.

[0100] The working principle of the sterilization module will be described in detail below in combination with a specific application scenario, taking the floor washer as an example of the cleaning device.

[0101] Application Scenario 1

[0102] The user is using a floor washer to clean the ground, and a sterilization module is provided inside the floor washer. The user first selects the hydrogen peroxide mode through the operation interface of the floor washer. When the controller in the floor washer receives this instruction, the controller controls the water supply module 2 to supply water to the sterilization module 3, and controls the first electrolysis module and / or the second electrolysis module to conduct electricity and connect. In this way, the first electrolysis module electrolyzes to generate ozone when powered on, and the second electrolysis module generates hydrogen peroxide. The ozone and / or hydrogen peroxide flow through the internal pipeline of the floor washer to the water spraying plate of the floor brush assembly 1 and are sprayed onto the ground from the water spraying plate. The stains on the ground are quickly decomposed and dissolved in water under the action of ozone and / or hydrogen peroxide, and then are swept by the roller brush.

[0103] For example, when the floor scrubber is operating, the second electrolysis module is electrically connected to produce hydrogen peroxide, while the first electrolysis module is not. The stain sensor on the floor brush 1 is constantly detecting the degree of dirtiness on the floor. When the stain sensor detects a large area of contamination or stubborn stains on the floor, the floor scrubber's operating interface allows the user to manually select whether to use the ozone mode. The first electrolysis module is turned on to produce ozone, thereby forming a cleaning liquid containing both hydrogen peroxide and ozone. This cleaning liquid is sprayed from the spray plate of the floor brush assembly 1, thereby cleaning stubborn stains on the floor. Alternatively, the cleaning mode can be automatically switched to the ozone cleaning mode upon a signal from the stain sensor, without user selection. In the above-mentioned cleaning mode containing ozone, the cleaning liquid can be a cleaning liquid containing both ozone and hydrogen peroxide, or a cleaning liquid containing only ozone. Of course, the floor scrubber can also have the first and second electrolysis modules in the sterilization module constantly turned on to produce different electrolysis products during normal cleaning operation, without the need to electrolyze to produce different electrolysis products based on the degree of dirtiness on the floor.

[0104] Application Scenario 2

[0105] After the user completes the floor cleaning work with the floor scrubber, the user places the floor scrubber on the cleaning base station. The cleaning base station detects that the roller brush in the floor brush 1 is dirty, so the cleaning base station sends a command to the floor scrubber to control the floor scrubber to start the self-cleaning mode.

[0106] When the controller in the floor scrubber receives the instruction, the controller will control the rotation of the roller brush and the water spray plate to spray water onto the roller brush. At the same time, the controller will also control the conduction of the first electrolysis module to ensure that ozone is continuously generated during the self-cleaning process. During the self-cleaning process, part of the ozone in the cleaning liquid sprayed onto the roller brush will evaporate to form ozone gas. The cleaning liquid containing ozone cleans and disinfects the parts that can enter the roller brush, pipes, and recycling barrels, while the volatilized ozone gas can enter the parts that the cleaning liquid cannot enter. For example, the part above the full liquid level of the recycling barrel cannot be disinfected and sterilized by the cleaning liquid, but can be disinfected and sterilized by the ozone gas. The ozone gas diffuses along the pipes inside the floor scrubber and can perform comprehensive sterilization and deodorization on the inner wall of the roller brush cavity, filter cotton and other components in the floor scrubber. At the same time, for the cleaning tray with drying function, since the solubility of ozone will decrease with the increase of temperature, after the self-cleaning is completed, the hot air flow will cause the ozone in the cleaning liquid that wets the roller brush to further evaporate, and along with the suction airflow generated by the negative pressure motor, the components between the roller brush cavity and the negative pressure motor are sterilized and disinfected, thereby performing secondary cleaning of the roller brush and suction pipeline and other components with ozone gas to achieve sterilization and deodorization.

[0107] As can be seen, in the technical solution provided by this application, a sterilization module and a water supply module are provided inside the cleaning device. The water supply module is connected to the electrolysis chamber of the sterilization module, and it can supply the liquid in the water tank to the electrolysis chamber. The above-mentioned clear water can be used as the stock solution for the electrolysis reaction. In the electrolysis chamber, the first electrolysis module and the second electrolysis module sharing the same electrolysis part (i.e., the third electrolysis part) can generate different cleaning substances through electrolysis. The first and second electrolysis modules have catalysts with different compositions. By specially designing the composition of the catalyst, during the electrolysis process, the first electrolysis part in the first electrolysis module can generate products such as peroxy ozone with the third electrolysis part through its specific catalyst, while the second electrolysis part in the second electrolysis module can generate cleaning products such as hydrogen peroxide or hypochlorous acid or silver ions with the third electrolysis part through its specific catalyst. In the solution of this application, the polarities of the first electrolysis part and the second electrolysis part are the same, and the polarity of the third electrolysis part is opposite to that of the first electrolysis part. By setting the third electrolysis part as the anode or the cathode, it is possible to achieve two anodes sharing one cathode or two cathodes sharing one anode, which can make the electrochemical reaction in the electrolysis chamber more concentrated and efficient. At the same time, the first and second electrolysis modules, through different catalysts, can cooperate with the shared third electrolysis part to generate different cleaning substances during the electrolysis process. With the above structure, the sterilization module can not only generate hydrogen peroxide or hypochlorous acid or ozone or silver ions alone, but also generate combinations such as hydrogen peroxide + ozone or hypochlorous acid + ozone or hydrogen peroxide + hypochlorous acid or hydrogen peroxide + silver ions. The sterilization module can adapt to different cleaning and disinfection requirements and can perform customized sterilization and deodorization treatments for different components and environments.

[0108] The above are only the preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application shall be included in the protection scope of this application.
