This cleaning device has a relatively simple structure, with a mounting bracket equipped with slots for installing the electrolytic plates, and contact pins to ensure electrical connectivity. Compared to the complex physical filtration, circulation, and chemical treatment systems required for recirculating disinfection, this device is easy to install, operate, and maintain. Its simple structure also reduces the probability of equipment failure and reduces the difficulty and cost of repairs associated with complex equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0037] See also Figure 1 In the first aspect, the present invention provides a cleaning device 100, which includes a fixing frame 1, an electrolytic sheet 2 and a contact pin 3 (see Figure 2 ). See Figure 3 The holder 1 has a first surface 11 and a second surface 12 that face each other along its thickness. The holder 1 is provided with a slot 13 that extends through both surfaces 11 and 12. The electrolytic sheet 2 includes a bent, connected extension portion 21 and an abutment portion 22. The extension portion 21 is inserted into the slot 13 and extends away from the first surface 11. The abutment portion 22 is located outside the slot 13 and abuts the second surface 12. The electrolytic sheet 2 is used to generate ozone when energized. The contact pin 3 is provided on the second surface 12 and is electrically connected to the abutment portion 22.

[0038] The cleaning device 100 in the embodiment of the present application has low cost, does not affect the normal use of the swimming pool during the cleaning process, can save water resources, has better disinfection effect, has no chemical residue, causes little damage to swimming pool equipment, has a simple structure, is easy to operate, has high disinfection efficiency, and is highly adaptable.

[0039] Specifically, contact pin 3 is used to connect to a power source, energizing electrolytic sheet 2. Water flowing through electrolytic sheet 2 is electrolyzed to form ozone. Ozone is a strong oxidant that can sterilize and disinfect, oxidizing and inactivating bacteria, viruses, and algae. It can also decompose organic pollutants in pool water, such as human secretions. By oxidizing these organic substances, it reduces their accumulation in the pool water, thereby reducing turbidity and odor, and improving water clarity and transparency. Ozone can also oxidize and remove some reducing inorganic pollutants. After ozone disinfection is complete, it gradually decomposes into oxygen at room temperature, leaving no chemical residue.

[0040] Compared to a complete water change, a complete water change requires draining all the pool water and refilling it with new water, a labor-intensive and costly undertaking, including water charges and labor costs for draining and refilling. The cleaning device 100, on the other hand, only needs to be installed in the pool, where it uses the electrolytic sheet 2 to generate ozone for cleaning and disinfection. After initial installation, subsequent operating costs are relatively low. While the pool cannot be used normally during the complete water change, the cleaning device 100 can continue operating while the pool is in normal use, providing real-time cleaning and disinfection of the pool water without disrupting normal operations. Complete water changes consume a significant amount of water resources. By continuously purifying and disinfecting the water, the cleaning device 100 reduces water waste and is more environmentally friendly. Detergent disinfection primarily involves chemical disinfection of pool water, which can be incomplete, especially for some highly resistant bacteria and viruses. Ozone, with its strong oxidizing properties, can rapidly destroy the cell walls and membranes of bacteria, viruses, and other microorganisms, as well as enzymes and nucleic acids within them, rendering them inactive and resulting in a more pronounced and thorough disinfection effect. Disinfection with detergents may leave chemical residues in pool water, potentially posing a health hazard to humans, such as respiratory irritation and skin allergies. However, the ozone generated by the cleaning device 100 naturally decomposes into oxygen after disinfection, leaving no chemical residue in the water and making it safer for swimmers. Some detergents can corrode pool equipment and pipes, shortening their service life. Ozone disinfection, on the other hand, does not corrode or damage pool equipment, extending its service life. Circulation disinfection requires complex filtration and circulation systems, as well as disinfection equipment. This complex system structure requires specialized personnel for operation and maintenance, resulting in high maintenance costs. The cleaning device 100 has a relatively simple structure, primarily consisting of a mounting frame 1, an electrolytic sheet 2, and a contact pin 3, making it easy to install and use. Circulation disinfection requires filtering the water before disinfection, a process that takes time. However, the electrolytic sheet 2 of the cleaning device 100 rapidly generates ozone upon powering on. Ozone reacts quickly with pollutants and microorganisms in the water, resulting in more efficient disinfection and achieving cleanliness standards in a short period of time. In some small swimming pools or swimming pools with special shapes, the circulation treatment system may not be able to fully cover all areas, resulting in uneven cleaning and disinfection effects. The cleaning device 100 can be installed in different locations of the swimming pool as needed to effectively clean and disinfect various areas, with greater adaptability.

[0041] See also Figure 3Furthermore, by inserting the extension portion 21 of the electrolytic sheet 2 into the slot 13 of the fixing frame 1, and with the abutment portion 22 resting against the second surface 12 of the fixing frame 1, the dual fixing structure of the slot 13 and the abutment portion 22 further stabilizes the position of the electrolytic sheet 2 in the device. The restraint of the extension portion 21 by the slot 13 effectively prevents displacement of the electrolytic sheet 2 during use, particularly under conditions such as pool water impact or equipment vibration. This ensures that the electrolytic sheet 2 remains in the proper working position, facilitating continuous and stable ozone production. The design of the slot 13 makes installation of the electrolytic sheet 2 simple and intuitive. The operator simply inserts the extension portion 21 of the electrolytic sheet 2 into the slot 13 to complete initial installation, then connects the contact pin 3 to the abutment portion 22 to achieve electrical continuity. This installation method is more convenient than designs that require complex welding or screw fixing, reducing installation difficulty and cost, and improving installation efficiency. This structure also offers significant advantages when maintaining or replacing the electrolytic sheet 2. The old electrolytic sheet 2 can be easily pulled out from the slot 13 and then a new electrolytic sheet 2 can be inserted. Compared with designs in which the electrolytic sheet 2 is tightly integrated with a fixed structure and difficult to disassemble, maintenance time and workload are greatly shortened.

[0042] See also Figure 2 Contact pins 3 are positioned on second surface 12, closely adjacent to contact portion 22 of electrolytic sheet 2, ensuring good electrical contact. This short-distance, direct connection reduces electrical resistance and improves power transmission efficiency, enabling electrolytic sheet 2 to more effectively convert electrical energy into the chemical energy required for ozone production. Compared to electrical connections achieved through long wires or complex connection structures, this method better ensures the efficiency and quality of ozone production. The compact structure and stable connection help reduce sparks and other issues caused by poor contact, improving electrical safety and reducing the risk of damage to the cleaning device 100 and the pool environment due to electrical failures.

[0043] In an optional embodiment, the fixing frame 1 may be circular or square.

[0044] In an optional embodiment, the electrolytic sheet 2 may be linear or curved. It is understood that since the extension portion 21 of the electrolytic sheet 2 is inserted into the slot 13, the shape of the slot 13 is consistent with the shape of the electrolytic sheet 2, that is, the slot 13 is linear or curved.

[0045] See also Figure 4 and Figure 7In some embodiments, the electrolytic sheet 2 and the slot 13 continuously curve and spiral about the center of the first surface 11 as the spiral axis. Increased ozone production: The spiral design of the electrolytic sheet 2 significantly increases the surface area of ​​the electrolytic sheet 2 in the water. Since ozone is produced through electrochemical reactions on the surface of the electrolytic sheet 2, a larger surface area means more reaction sites. Compared to a flat electrolytic sheet 2, this spiral structure can produce more ozone with the same power supply, thereby improving the disinfection and purification efficiency of pool water. Enhanced contact with water: The curved, spiral structure ensures more effective contact between the electrolytic sheet 2 and the pool water. Water can flow through the spiral electrolytic sheet 2, ensuring full contact with the surface of the electrolytic sheet 2, facilitating the timely diffusion of ozone into the water and enabling it to react more effectively with pollutants and microorganisms in the water. Evenly distributed ozone: The spiral structure promotes a more even distribution of ozone in the pool water. When the electrolytic sheet 2 produces ozone, it gradually diffuses with the water flow around the spiral structure. This spiral distribution method avoids the situation where the ozone concentration is too high or too low in local areas, making the ozone concentration in the entire swimming pool more balanced, thereby more comprehensively cleaning and disinfecting the pool water without any cleaning dead corners. Promote water circulation: The continuously curved and spiraling electrolytic sheet 2 and the card slot 13 structure will disturb the surrounding water flow. This disturbance can cause the pool water to form a more complex water circulation, so that water from far away can also be continuously guided to the vicinity of the electrolytic sheet 2 for treatment. This is especially important for large swimming pools or areas where the water flow is relatively static, and can ensure that the water in the entire pool is effectively cleaned and treated. Save space: Within the limited space of the fixing frame 1, the spiral structure can greatly increase the length and area of ​​the electrolytic sheet 2 without increasing the size of the fixing frame 1. This allows the cleaning device 100 to have stronger cleaning capabilities while maintaining a small size, making it more suitable for installation in swimming pools of various shapes and sizes, improving the space utilization and adaptability of the device.

[0046] Understandably, see Figure 4 and Figure 5The extension portion 21 and the abutment portion 22 of the electrolytic sheet 2 are both continuously bent and coiled with the center of the first surface 11 of the fixing frame 1 as the spiral axis. The continuously bent and coiled extension portion 21 and abutment portion 22 make the electrolytic sheet 2 itself form a relatively stable overall structure. This structure is less likely to deform or displace under the impact of the swimming pool water flow than the electrolytic sheet 2 with a simple shape. The various parts support and restrict each other, which can better maintain the position in the fixing frame 1, ensure the connection stability of the electrolytic sheet 2 and other components such as the contact pin 3, and ensure stable power supply and ozone generation process. The spiral structure makes the current distribution on the electrolytic sheet 2 more uniform, avoiding the situation where the local current is too large or too small. This uniform current distribution helps to improve the electrolysis efficiency and reduce problems such as local overheating or incomplete electrolysis reaction caused by uneven current. Under the same electrical energy input, ozone can be produced more efficiently, improving the energy utilization efficiency of the entire cleaning device 100.

[0047] See also Figure 4 In some embodiments, the electrolyte sheet 2 includes an anode electrolyte sheet 23 and a cathode electrolyte sheet 24 that are spaced apart. Figure 7 The card slot 13 includes a first card slot 131 and a second card slot 132 that are spaced apart. Figure 8 , the contact pin 3 includes a positive contact pin 31 and a negative contact pin 32. Figure 4 and Figure 7 The anode electrolyte sheet 23, the cathode electrolyte sheet 24, the first slot 131 and the second slot 132 are simultaneously continuously bent and spiraled around the center of the first surface 11 as the spiral axis. Figure 5 The anode electrolyte sheet 23 is inserted into the first card slot 131, and the cathode electrolyte sheet 24 is inserted into the second card slot 132. The anode electrolyte sheet 23 is electrically connected to the positive electrode contact pin 31, and the cathode electrolyte sheet 24 is electrically connected to the negative electrode contact pin 32. It should be noted that water produces oxygen and ozone on the anode electrolyte sheet 23, and water produces hydrogen on the cathode electrolyte sheet 24. By providing independent card slots 13 and contact pins 3 for the anode electrolyte sheet 23 and the cathode electrolyte sheet 24 respectively, the current is evenly distributed throughout the electrolysis system. Compared with a single electrode or asymmetric electrode design, it can reduce the phenomenon of local current overload or uneven current density, reduce the risk of damage such as overheating and corrosion of the electrolyte sheet 2 due to current problems, and improve the stability and reliability of the device.

[0048] In an optional embodiment, the spiral directions of the anode electrolyte sheet 23 and the cathode electrolyte sheet 24 are the same or different. Figure 4The anode and cathode sheets 23 and 24 have the same spiral direction. This creates a synergistic water flow effect: When the anode and cathode sheets 23 and 24 have the same spiral direction, they disrupt the surrounding water flow in the same direction during operation. This consistent disturbance helps create a more orderly and stable water flow pattern in the pool. For example, guided by the spiral structure, water can flow more smoothly in a specific direction, allowing the water in the pool to circulate more quickly and avoiding dead spots. This ensures that water both near and far from the electrolyte sheet 2 is treated more efficiently, improving the overall cleaning efficiency of the pool water. It also promotes uniform gas mixing and diffusion: The same spiral direction facilitates the mixing and diffusion of gases (oxygen, ozone, and hydrogen) generated by the anode and cathode in the water. Guided by the unified spiral flow, the gases are more evenly distributed in the pool water, eliminating the chaotic distribution or localized concentration of ozone that can occur due to different electrode spiral directions. This uniform gas distribution ensures that every part of the water is fully exposed to the cleansing ozone, enhancing the cleaning effect in all areas of the pool. Stable electric field distribution: Under the same spiral direction, the electric field distribution between the anode and cathode is more stable and regular. This stable electric field helps maintain a stable electrolysis process and reduces local abnormal electrolysis phenomena that may be caused by uneven electric fields, such as local current overshoot or undershoot, local corrosion on the electrode surface, and other problems. A stable electrolysis process helps extend the service life of the electrolytic sheet 2 and improve the reliability of the entire cleaning device 100. Reduced electrical interference risk: Due to the same spiral direction, electrical signal interference between the anode and cathode is reduced. Compared to the complex electromagnetic environment that may be caused by different spiral directions, this reduces the risk of failure caused by electrical interference. For example, it avoids problems such as poor contact between the contact pin 3 and the electrolytic sheet 2 or signal transmission errors caused by electromagnetic interference, thereby improving the safety and stability of the device. Simplified design and manufacturing process: From the perspective of device design and manufacturing, maintaining the same spiral direction for the anode electrolytic sheet 23 and the cathode electrolytic sheet 24 can simplify the design process and manufacturing process. During the production process, there is no need to design complex supporting structures or manufacturing processes for electrodes with different spiral directions, reducing production costs and production difficulties, and improving production efficiency. Easier installation and maintenance: Electrodes with the same spiral orientation are easier for installers to install and debug. During installation, it's easier to determine the electrode's position and connection method, reducing installation errors that can occur due to complex electrode orientations. Subsequent maintenance also makes it easier to inspect, repair, or replace the anode and cathode, reducing maintenance costs and complexity.

[0049] See also Figure 9In some embodiments, the anodic and cathodic sheets 23 and 24 are staggered along the radial direction of the spiral, with the pitch d between one circle of anodic and cathodic sheets 23 and its adjacent circle of cathodic sheets 24 being the same. Optimizing the electric field distribution: The staggered arrangement makes the electric field distribution between the anodic and cathodic sheets 23 and 24 more uniform and reasonable. During the electrolysis process, a uniform electric field promotes orderly electron migration, thereby improving electrolysis efficiency. Relatively independent yet interconnected micro-electric fields are formed between each anodic and cathodic sheet 23 and its adjacent cathodic sheet 24. These micro-electric fields work synergistically to promote more efficient electrolysis of water molecules on the electrode surface, increasing the production of ozone and other gases (such as oxygen and hydrogen). This uniform electric field distribution also reduces local overheating caused by concentrated or uneven electric fields, reduces electrode wear, and extends the service life of the electrolytic sheet 2. Utilizing the electrode surface: The staggered arrangement maximizes the surface area of ​​the anodic and cathodic sheets 23 and 24. This allows more electrode surface area to participate in the electrolysis reaction, increasing the number of active sites per unit volume, further improving ozone production efficiency and facilitating disinfection and purification of pool water. Promotes gas mixing: The staggered arrangement of the anode and cathode allows for better mixing of gases (oxygen and ozone) and hydrogen (hydrogen) produced by the cathode. Guided by the spiral structure, the gases, due to the staggered arrangement of the anode and cathode, come into contact and mix over a shorter distance, forming a more uniform gas mixture. This uniform gas mixture diffuses more effectively in the water, providing more comprehensive coverage across the pool and preventing uneven gas composition that could affect cleaning effectiveness in certain areas. The consistent pitch of adjacent spiral turns ensures a consistent rhythm of gas generation and diffusion. Within each spiral turn, the gas generation and diffusion rate remain relatively stable, fostering a stable and uniform gas distribution throughout the pool water, ensuring comprehensive purification of every area. Orderly water flow disturbance: The staggered electrode structure creates a more orderly disturbance of the surrounding water flow. In the direction of spiral rotation, the water flow is subjected to alternating forces as it passes through the anode and cathode. This alternating force helps form a complex but orderly water flow pattern. In this pattern, the water flow can more fully contact the electrode surface, improving the mass transfer efficiency between the water and the electrodes and facilitating the electrolysis reaction. The uniform pitch design ensures that this water flow disturbance is consistent throughout the entire spiral structure. There will be no sudden changes in the water flow due to pitch changes, allowing the water flow to circulate more smoothly within the pool, delivering the generated gas more evenly to every corner of the pool and improving the cleaning efficiency of the entire pool water. Balancing the interaction between electrodes: The staggered interval setting can balance the interaction between the anode and cathode. During the electrolysis process, the mutual influence between the electrodes may lead to some unstable factors, such as changes in the local chemical environment and fluctuations in the electrode surface potential.This layout effectively alleviates these issues, stabilizing the interaction between electrodes, reducing the probability of failures caused by mutual interference, and improving the overall stability of the device. The stable pitch design further ensures the continuity of this balance. Over long-term operation, the device maintains stable electrolysis and gas production, reducing maintenance frequency and costs, and extending its service life.

[0050] See also Figure 9 For example, the pitch d between a circle of anode electrolyte sheets 23 and an adjacent circle of cathode electrolyte sheets 24 is 2 mm to 5 mm, for example, 2 mm, 3 mm, 4 mm, 5 mm, etc.

[0051] See also Figure 2 In some embodiments, the cleaning device 100 further includes an electrolyte sheet pressing block 4, which is disposed on the second surface 12 of the fixing frame 1 and abuts the abutment portion 22. The electrolyte sheet pressing block 4 is provided with an embedding hole 41 extending through its thickness. The contact pin 3 is inserted into the embedding hole 41, and the end face of the contact pin 3 is exposed through the embedding hole 41 to electrically connect with the abutment portion 22. By providing the electrolyte sheet pressing block 4, the contact pin 3 is pre-embedded within the electrolyte sheet pressing block 4. The electrolyte sheet pressing block 4 provides a fixed support for the contact pin 3, ensuring that the contact pin 3 is accurately positioned, thereby ensuring a stable electrical connection between the contact pin 3 and the abutment portion 22 of the electrolyte sheet 2. At the same time, the electrolyte sheet pressing block 4 can press against the abutment portion 22 of the electrolyte sheet 2, further securing the electrolyte sheet 2, preventing displacement or shaking of the electrolyte sheet 2, and ensuring a stable relative position between the electrolyte sheet 2, the fixing frame 1, and the contact pin 3. In addition, the covering and fixing of the contact pin 3 and the abutment portion 22 by the electrolytic sheet pressing block 4 creates a relatively closed environment for the electrical connection to a certain extent, reduces the corrosion and interference of the electrical connection parts, reduces the risk of electrical failures caused by factors such as chemical corrosion or short circuits, and extends the service life of electrical components. When assembling the cleaning device 100, the electrolytic sheet pressing block 4 pre-positions the contact pin 3, making the assembly process simpler and more accurate. The operator only needs to install the electrolytic sheet pressing block 4 with the contact pin 3 on the fixing frame 1 to achieve the connection between the contact pin 3 and the abutment portion 22 of the electrolytic sheet 2. There is no need to perform a separate complex positioning operation on the contact pin 3, which improves the assembly efficiency, reduces the assembly difficulty and labor cost, and is also convenient for maintenance.

[0052] See also Figure 10 In an optional embodiment, a first step 14 is provided on the periphery of the fixing frame 1, and a second step 42 is provided on the periphery of the electrolyte sheet compact 4. The second step 42 abuts against the first step 14 to connect the electrolyte sheet compact 4 to the fixing frame 1. The first step 14 and the second step 42 can be ultrasonically welded.

[0053] In an optional embodiment, the electrolyte sheet compact 4 may be round or square, matching the shape of the fixing frame 1 .

[0054] It is understandable that, since the abutting portion 22 of the electrolytic sheet 2 has a certain thickness, when the electrolytic sheet compact 4 abuts against the abutting portion 22 , a gap exists between the side surface of the electrolytic sheet compact 4 and the second surface 12 .

[0055] See also Figure 11 In an optional embodiment, the cleaning device 100 further includes a foolproof structure 6. The foolproof structure 6 is provided on the side of the electrolytic sheet compact 4 away from the second surface 12, and is used to prevent docking errors during installation of the electrolytic sheet compact 4.

[0056] See also Figure 1 In some embodiments, the cleaning device 100 further includes a mesh cover 5 rotatably connected to the first surface 11 of the fixing frame 1 and covering the fixing frame 1 and the electrolytic sheet 2. The mesh cover 5 defines a storage space within which the electrolytic sheet 2 is located. The mesh cover 5 protects the electrolytic sheet 2 and the fixing frame 1. The mesh cover 5 can rotate relative to the fixing frame 1, thereby promoting water flow and thereby enhancing the ozone's cleaning effect on the water. In alternative embodiments, the mesh cover 5 can also be stationary.

[0057] In an optional embodiment, the mesh cover 5 may be circular or square, and the shape of the mesh cover 5 matches the shape of the fixing frame 1 .

[0058] Second, see Figure 12 The present invention also provides a cleaning device 1000, which includes a housing 200 and a cleaning device 100 according to the first aspect. The cleaning device 100 is connected to the housing 200. The present invention does not limit the position of the cleaning device 100 on the housing 200. The cleaning device 100 can be arranged outside the housing 200 or inside the housing 200.

[0059] See also Figure 13 In some embodiments, the housing 200 is provided with a mounting cavity 201, see Figure 14 and Figure 15 The side wall of the box body 200 is provided with a mounting groove 202 communicating with the mounting cavity 201 and a mounting hole 203 communicating with the mounting groove 202. The cleaner 1000 also includes an electrical connection structure 300. Figure 16 The electrical connection structure 300 includes a power socket 301, a power female plug 302 and a power line 303. The power female plug 302 and the power line 303 are both embedded in the power socket 301. The power female plug 302 is electrically connected to the power line 303. Figure 15The power socket 301 is plugged into the mounting hole 203, the power line 303 is located in the mounting cavity 201, the end of the power female plug 302 is exposed in the mounting groove 202, the cleaning device 100 is fixed in the mounting groove 202, and the contact pin 3 of the cleaning device 100 is plugged into the power female plug 302. Arranging the cleaning device 100 in this way can simplify the installation process and facilitate maintenance and replacement. The power female plug 302 and the power line 303 are embedded in the power socket 301. This structure ensures the stability of the connection between the two. The contact pin 3 of the cleaning device 100 is inserted into the power female plug 302 to form a tight electrical connection, reducing poor contact caused by factors such as vibration and water flow impact. During the long-term operation of the swimming pool, a stable current supply can be ensured to ensure that the cleaning device 100 can normally produce ozone for cleaning. The design of the mounting groove 202 and the mounting hole 203 provides a certain degree of protection for the electrical connection, preventing foreign matter from directly contacting the connection between the power female plug 302 and the contact pin 3, reducing the possibility of corrosion and short circuit. The wrapping of the power socket 301 on the internal electrical components further enhances the protection capability, prolongs the service life of the electrical connection structure 300 , and ensures the reliability of the electrical system of the cleaner 1000 .

[0060] See also Figure 13 In some embodiments, the cleaner 1000 further includes a roller brush 400. The housing 200 further includes a collection tank 204 and a collection port 205 connected to the collection tank 204. The roller brush 400 is rotatably connected to the housing 200. The roller brush 400 can rotate at high speed to sweep foreign matter in the swimming pool into the collection tank 204 for collection.

[0061] See also Figure 13 In some embodiments, the cleaner 1000 further includes a guide baffle 500 connected to the housing 200 and located outside the collection port 205. The side of the guide baffle 500 away from the collection port 205 is higher than the side close to the collection port 205. Thus, the guide baffle 500 has an inclined surface, which can guide foreign matter in the swimming pool into the collection port 205, where it is swept into the collection trough 204 by the roller brush 400 for collection.
