Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a cleaning device and a cleaning apparatus. Background Art

[0002] The main methods of swimming pool cleaning include overall water replacement, adding detergents for disinfection, and circulating treatment disinfection. Circulating treatment disinfection refers to physical filtration combined with chemical treatment. Overall water replacement is costly, wastes water resources, and requires a large amount of work; adding detergents for disinfection is prone to chemical residues, which are harmful to human health; circulating treatment requires complex filtration, circulation, and disinfection systems, and the system structure is complex.

[0007] A contact pin is disposed on the second surface and electrically connected to the abutting portion.

[0008] In one embodiment, the electrolyte sheet and the slot are continuously bent and spiraled with the center of the first surface as the spiral axis.

[0010] In one embodiment, the anode electrolyte sheet and the cathode electrolyte sheet have the same spiral direction; and / or, along the radial direction of the spiral, the anode electrolyte sheet and the cathode electrolyte sheet are arranged alternately, and the pitch between a circle of the anode electrolyte sheet and an adjacent circle of the cathode electrolyte sheet is the same.

[0011] In one embodiment, the cleaning device also includes an electrolyte sheet press block, which is arranged on the second surface of the fixing frame and abuts against the abutment portion. The electrolyte sheet press block is provided with an embedding hole along its thickness direction, the contact pin is inserted into the embedding hole, and the end face of the contact pin is exposed to the embedding hole to be electrically connected to the abutment portion.

[0012] In one embodiment, the cleaning device further comprises a mesh cover, which is rotatably connected to the first surface of the fixing frame and covers the fixing frame and the electrolytic sheet. The mesh cover has a receiving space, and the electrolytic sheet is located in the receiving space.

[0013] In a second aspect, a cleaner comprises a housing and the cleaning device as described in the first aspect, wherein the cleaning device is connected to the housing.

[0014] In one embodiment, the box body is provided with an installation cavity, and the side wall of the box body is provided with an installation groove connected to the installation cavity and a installation hole connected to the installation groove, and the cleaner also includes an electrical connection structure, and the electrical connection structure includes a power-on seat, a power-on female plug and a power-on wire, the power-on female plug and the power-on wire are both embedded in the power-on seat, the power-on female plug is electrically connected to the power-on wire, the power-on seat is plugged into the installation hole, the power-on wire is located in the installation cavity, the end of the power-on female plug is exposed in the installation groove, the cleaning device is fixed in the installation groove, and the contact pin of the cleaning device is plugged into the power-on female plug.

Only by installing the cleaning device and paying a small amount of electricity cost for the electrolytic sheet to work, the continuous cleaning of the swimming pool water can be achieved, which greatly reduces the cost of long-term maintenance of the swimming pool cleaning. Compared with adding detergents for disinfection, there is no need to continuously purchase a large amount of detergents, which further saves the cleaning cost. At the same time, due to the good disinfection effect of ozone, other auxiliary costs that need to be increased due to incomplete disinfection are reduced. Unlike the circulation treatment disinfection, this cleaning device has a simple structure, mainly composed of a fixed frame, an electrolytic sheet and a contact pin, and does not need to be equipped with a complex and expensive filtering, circulation and disinfection system, thereby reducing the purchase cost, installation cost and maintenance cost of the equipment.

However, the cleaning device works in the existing water environment of the swimming pool, purifies and disinfects the swimming pool water through the strong oxidizing property of ozone, realizes the recycling of water resources, and avoids unnecessary waste of water resources. The cleaning device uses electrolytic sheets to generate ozone for disinfection, and ozone will naturally decompose into oxygen after the disinfection process is completed. Unlike disinfection by adding detergent, no chemical residue will be left in the pool water, eliminating the potential risk of harm to human health and ensuring the safety and health of swimmers. The structure of this cleaning device is relatively simple. A card slot is set on the fixed frame for installing the electrolytic sheet, and the contact pin ensures the electrical connection of the electrolytic sheet. Compared with the complex physical filtration, circulation system and chemical agent treatment system in the circulation treatment 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 maintenance caused by the complexity of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0037] Please refer to FIG1 . In the first aspect, the embodiment of the present application provides a cleaning device 100 , which includes a fixing frame 1 , an electrolytic sheet 2 , and a contact pin 3 (see FIG2 ). Please refer to FIG3 . The fixing frame 1 has a first surface 11 and a second surface 12 that are opposite to each other along its thickness direction, and the fixing frame 1 is provided with a card slot 13 that penetrates the first surface 11 and the second surface 12 at the same time. The electrolytic sheet 2 includes a bent extension portion 21 and an abutment portion 22 . The extension portion 21 is inserted into the card slot 13 and extends in a direction away from the first surface 11 . The abutment portion 22 is located outside the card slot 13 and abuts against the second surface 12 . The electrolytic sheet 2 is used to generate ozone by energizing. 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 has strong adaptability.

[0039] Specifically, the contact pin 3 is used to connect the power supply to energize the electrolytic sheet 2, and the water flows through the electrolytic sheet 2 to form ozone by electrolysis. Ozone is a strong oxidant that can sterilize and disinfect, and can oxidize and inactivate bacteria, viruses, algae, etc. At the same time, ozone can decompose organic pollutants in swimming pool water, such as human secretions, etc. It can decompose these organic substances by oxidation, reduce their accumulation in swimming pool water, and then reduce the turbidity and odor in swimming pool water, improve the clarity and transparency of water quality, and at the same time, ozone can oxidize and remove some reducing inorganic pollutants. After ozone disinfection is completed, it will gradually decompose into oxygen at room temperature without forming chemical residues.

[0040] Compared with the overall water change: the overall water change needs to drain all the water in the swimming pool and then inject new water, which is a large project with high costs, including water charges, labor costs for drainage and water injection, etc. The cleaning device 100 only needs to be installed in the swimming pool, and the ozone is generated by the electrolytic sheet 2 for cleaning and disinfection. The subsequent use cost after the initial installation is relatively low. During the overall water change process, the swimming pool cannot be used normally. The cleaning device 100 can continue to work under the condition of normal use of the swimming pool, and clean and disinfect the swimming pool water in real time without affecting the normal operation of the swimming pool. Overall water change consumes a lot of water resources. The cleaning device 100 reduces the waste of water resources by continuously purifying and disinfecting water, which is more environmentally friendly. Detergent disinfection mainly uses chemical agents to disinfect swimming pool water, and there may be incomplete disinfection, especially for some bacteria and viruses with strong drug resistance. Ozone has strong oxidizing properties and can quickly destroy the cell walls, cell membranes, and internal enzymes, nucleic acids and other substances of microorganisms such as bacteria and viruses, making them inactive, and the disinfection effect is more significant and thorough. Detergent disinfection may leave chemical residues in the swimming pool water, which may cause potential harm to human health, such as irritation to the respiratory tract and skin allergies. The ozone generated by the cleaning device 100 will naturally decompose into oxygen after the disinfection is completed, and will not produce chemical residues in the water, which is safer for the health of swimmers. Some detergents may corrode the equipment and pipes of the swimming pool, shortening the service life of the equipment. Ozone disinfection will not cause corrosion and other damage to the swimming pool equipment, which is conducive to extending the service life of the swimming pool equipment. Circulation treatment disinfection requires complex filtration, circulation systems and disinfection equipment. The system structure is complex, and operation and maintenance require professionals, and the maintenance cost is high. The cleaning device 100 has a relatively simple structure, mainly composed of a fixing frame 1, an electrolytic sheet 2 and a contact pin 3, and is easy to install and use. Circulation treatment disinfection requires filtering the water first and then disinfecting it. The whole process takes a certain amount of time. After the electrolytic sheet 2 of the cleaning device 100 is powered on, ozone can be quickly generated. Ozone can quickly react with pollutants and microorganisms in the water, and the disinfection efficiency is higher, which can make the swimming pool water reach the cleaning standard in a short time. In some small swimming pools or swimming pools of special shapes, the circulation treatment system may not be able to completely cover all areas, resulting in uneven cleaning and disinfection effects. The cleaning device 100 can be installed at different locations of the swimming pool as needed to effectively clean and disinfect various areas, and has stronger adaptability.

[0041] Please refer to FIG. 3 . Further, by inserting the extension portion 21 of the electrolytic sheet 2 into the slot 13 of the fixing frame 1 , and the abutment portion 22 abuts against the second surface 12 of the fixing frame 1 , the dual fixing structure design of the slot 13 and the abutment portion 22 makes the position of the electrolytic sheet 2 in the device more stable. The restriction of the extension portion 21 by the slot 13 can effectively prevent the electrolytic sheet 2 from being displaced during use, especially in the case of swimming pool water flow impact or equipment vibration, etc., which can ensure that the electrolytic sheet 2 is always in a suitable working position, which is conducive to the continuous and stable generation of ozone. The design of the slot 13 makes the installation of the electrolytic sheet 2 simple and intuitive. The operator only needs to insert the extension portion 21 of the electrolytic sheet 2 into the slot 13 to complete the preliminary installation, and then connect the contact pin 3 with the abutment portion 22 to achieve electrical conduction. This installation method is more convenient than some designs that require complex welding, screw fixing, etc., reduces the difficulty and cost of installation, and improves the installation efficiency. This structure also has obvious 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 combined with a fixed structure and is difficult to disassemble, the maintenance time and workload are greatly shortened.

[0042] Please refer to FIG. 2 , the contact pin 3 is disposed on the second surface 12 closely adjacent to the abutment portion 22 of the electrolytic sheet 2, which can ensure good electrical contact. This short-distance, direct connection method can reduce resistance, improve the efficiency of power transmission, and enable the electrolytic sheet 2 to more effectively convert electrical energy into the chemical energy required for ozone production. Compared with some methods of achieving electrical connection through long wires or complex connection structures, it can better ensure the efficiency and quality of ozone production. The compact structure and stable connection help reduce problems such as electric sparks caused by poor contact, improve electrical safety, and reduce the risk of damage to the entire cleaning device 100 and the swimming 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 understandable that, since the extension portion 21 of the electrolytic sheet 2 is inserted into the slot 13, the slot 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] Referring to FIG. 4 and FIG. 7 , in some embodiments, the electrolytic sheet 2 and the card slot 13 are continuously bent and spiraled with the center of the first surface 11 as the spiral axis. Increase the amount of ozone generated: The spiral electrolytic sheet 2 design greatly increases the surface area of ​​the electrolytic sheet 2 in the water. Since ozone is generated by electrochemical reactions on the surface of the electrolytic sheet 2, a larger surface area means more reaction sites. Compared with the planar electrolytic sheet 2, under the same power supply, this spiral structure can produce more ozone, thereby improving the disinfection and purification efficiency of the swimming pool water. Enhance the contact effect with water: The curved spiral structure makes the contact between the electrolytic sheet 2 and the swimming pool water more sufficient. Water can flow between the spiral electrolytic sheets 2, ensuring that the water is in full contact with the surface of the electrolytic sheet 2, which is conducive to the timely diffusion of ozone into the water, so that the ozone reacts more effectively with pollutants and microorganisms in the water. Uniform distribution of ozone: The spiral structure helps to form a more uniform distribution of ozone in the swimming pool water. When the electrolytic sheet 2 generates ozone, the ozone will gradually diffuse 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 a local area, making the ozone concentration in the entire swimming pool more balanced, so that the swimming pool water can be cleaned and disinfected more comprehensively without cleaning dead corners. Promote water circulation: The continuously curved and spiraled electrolytic sheet 2 and the card slot 13 structure will disturb the surrounding water flow. This disturbance can cause the swimming pool water to form a more complex water flow cycle, so that the water in the distance can also be continuously guided to the vicinity of the electrolytic sheet 2 for treatment. This is particularly important for large swimming pools or areas where the water flow is relatively static, and can ensure that the water in the entire swimming pool can be effectively cleaned. Save space: In 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 a stronger cleaning ability while maintaining a small volume, and is more suitable for installation in swimming pools of various shapes and sizes, improving the space utilization and adaptability of the device.

[0046] It can be understood that, referring to Figures 4 and 5, the extension 21 and the abutment 22 of the electrolytic sheet 2 are both continuously bent and coiled with the center of the first surface 11 of the fixed frame 1 as the spiral axis. The continuously bent and coiled extension 21 and abutment 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 of a simple shape. The mutual support and restriction between the various parts can better maintain the position in the fixed 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 distribution of current 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 power input, ozone can be generated more efficiently, which improves the energy utilization efficiency of the entire cleaning device 100.

[0047] Please refer to FIG4. In some embodiments, the electrolyte sheet 2 includes an anode electrolyte sheet 23 and a cathode electrolyte sheet 24 arranged at intervals, please refer to FIG7. The slot 13 includes a first slot 131 and a second slot 132 arranged at intervals, please refer to FIG8. The contact pin 3 includes a positive contact pin 31 and a negative contact pin 32. Please refer to FIG4 and FIG7. 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 with the center of the first surface 11 as the spiral axis, please refer to FIG5. The anode electrolyte sheet 23 is inserted in the first slot 131, and the cathode electrolyte sheet 24 is inserted in the second slot 132. The anode electrolyte sheet 23 is electrically connected to the positive contact pin 31, and the cathode electrolyte sheet 24 is electrically connected to the negative contact pin 32. It should be noted that water generates oxygen and ozone on the anode electrolyte sheet 23, and water generates hydrogen on the cathode electrolyte sheet 24. By providing independent slots 13 and contact pins 3 for the anode electrolytic sheet 23 and the cathode electrolytic sheet 24, the current is evenly distributed in the entire electrolytic system. Compared with a single electrode or asymmetric electrode design, the phenomenon of local current overload or uneven current density can be reduced, the risk of damage such as overheating and corrosion of the electrolytic sheet 2 caused by current problems is reduced, and the stability and reliability of the device are improved.

[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. Preferably, referring to FIG. 4 , the spiral directions of the anode electrolyte sheet 23 and the cathode electrolyte sheet 24 are the same. Forming a synergistic water flow effect: When the spiral directions of the anode electrolyte sheet 23 and the cathode electrolyte sheet 24 are the same, the disturbance direction of the surrounding water flow generated by them during operation is consistent. This consistent disturbance helps to form a more orderly and stable water flow pattern in the swimming pool. For example, under the guidance of the spiral structure, water can flow more smoothly along a specific direction, so that the water in the swimming pool can circulate more quickly and avoid dead corners of water flow. In this way, water away from or close to the electrolyte sheet 2 can be treated more efficiently, improving the cleaning efficiency of the entire swimming pool water. Promoting uniform mixing and diffusion of gases: The same spiral direction is conducive to better mixing and diffusion of gases (oxygen, ozone, hydrogen) generated by the anode and cathode in the water. Under the guidance of the spiral water flow in a uniform direction, the gas can be more evenly distributed in the swimming pool water, and there will be no disordered distribution or local enrichment of ozone due to different spiral directions of the electrodes. Uniform gas distribution can ensure that water in every place can fully contact the ozone with cleaning effect, and enhance the cleaning effect of each area of ​​the swimming pool. Stable electric field distribution: Under the same spiral direction, the electric field distribution between the anode and the cathode is more stable and regular. This stable electric field helps to maintain a stable electrolysis process and reduce local abnormal electrolysis phenomena that may be caused by uneven electric field, such as excessive or insufficient local current, local corrosion of the electrode surface, and other problems. The stable electrolysis process is conducive to extending the service life of the electrolytic sheet 2 and improving the reliability of the entire cleaning device 100. Reduced electrical interference risk: Due to the same spiral direction, the electrical signal interference between the anode and the cathode will be reduced. Compared with the complex electromagnetic environment that may be caused by different spiral directions, this reduces the risk of failure caused by electrical interference, such as avoiding problems such as poor contact between the contact pin 3 and the electrolytic sheet 2 or signal transmission errors caused by electromagnetic interference, and improves the safety and stability of the device. Simplified design and manufacturing process: From the perspective of device design and manufacturing, keeping the anode electrolytic sheet 23 and the cathode electrolytic sheet 24 in the same spiral direction 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, which reduces production costs and production difficulties and improves production efficiency. Convenient installation and maintenance: For installers, electrodes with the same spiral direction are easier to install and debug. During the installation process, it is easier to determine the position and connection method of the electrode, reducing installation errors that may be caused by complex electrode directions. In the subsequent maintenance process, it is also easier to inspect, repair or replace the anode and cathode, reducing maintenance costs and difficulties.

[0049] Please refer to FIG9. In some embodiments, along the radial direction of the spiral, the anode electrolyte sheet 23 and the cathode electrolyte sheet 24 are arranged at staggered intervals, and the pitch d between a circle of anode electrolyte sheets 23 and an adjacent circle of cathode electrolyte sheets 24 is the same. Optimizing the electric field distribution: The staggered interval arrangement makes the electric field distribution between the anode electrolyte sheet 23 and the cathode electrolyte sheet 24 more uniform and reasonable. During the electrolysis process, the uniform electric field helps the orderly migration of electrons, thereby improving the electrolysis efficiency. A relatively independent and interrelated micro-electric field is formed between each anode electrolyte sheet 23 and the adjacent cathode electrolyte sheet 24. These micro-electric fields work together to promote the electrolysis reaction of water molecules on the electrode surface more efficiently, increasing the production of ozone and other gases (such as oxygen and hydrogen). This uniform electric field distribution can also reduce local overheating caused by concentrated or uneven electric fields, reduce electrode losses, and extend the service life of the electrolyte sheet 2. Making full use of the electrode surface: The staggered arrangement can maximize the use of the surface area of ​​the anode electrolyte sheet 23 and the cathode electrolyte sheet 24. It can make more electrode surfaces participate in the electrolysis reaction, increase the number of active sites of the electrolysis reaction per unit volume, further improve the efficiency of ozone generation, and be more conducive to disinfection and purification of swimming pool water. Promote gas mixing: The gas (oxygen and ozone) generated by the anode and the hydrogen generated by the cathode can be better mixed in the staggered structure. Under the guidance of the spiral structure, the gas will contact and mix with each other in a shorter distance due to the staggered layout of the anode and cathode, forming a more uniform gas mixture. This uniform gas mixture has a better diffusion effect in the water, can cover all areas of the swimming pool more comprehensively, and avoid the impact of uneven gas composition on the cleaning effect in local areas. The design of the same pitch of adjacent circles ensures the consistency of the rhythm of gas generation and diffusion. In each circle of the spiral, the amount of gas generated and the diffusion rate are relatively stable, which is conducive to forming a stable and uniform gas distribution environment in the entire swimming pool water, so that every place of water can be fully purified. Orderly water flow disturbance: The staggered electrode structure produces more orderly disturbances to the surrounding water flow. In the direction of spiral rotation, the water flow is subjected to alternating forces when passing through the anode and cathode. This alternating force helps to form a complex but orderly water flow pattern. In this mode, the water flow can contact the electrode surface more fully, improve the mass transfer efficiency between water and electrode, and facilitate the electrolysis reaction. The same pitch design ensures that this water flow disturbance is consistent throughout the spiral structure. There will be no sudden changes in the water flow due to changes in pitch, so that the water flow can circulate more smoothly in the swimming pool, and the generated gas can be more evenly transported to every corner of the swimming pool, improving the cleaning efficiency of the entire swimming pool water. Balance the interaction between electrodes: The staggered interval setting can balance the interaction between the anode and the 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 can effectively alleviate these problems, making the interaction between electrodes more stable, reducing the probability of failure caused by mutual interference between electrodes, and improving the overall stability of the device. The stable pitch design further ensures the continuity of this balance. During long-term operation, the device can maintain a stable electrolysis and gas generation state, reduce maintenance times and repair costs, and extend the service life of the device.

[0050] Please refer to FIG9 , 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] Please refer to FIG. 2 . In some embodiments, the cleaning device 100 further includes an electrolytic sheet pressing block 4, which is arranged on the second surface 12 of the fixing frame 1 and abuts against the abutment portion 22. The electrolytic sheet pressing block 4 is provided with an embedding hole 41 along its thickness direction, and the contact pin 3 is inserted into the embedding hole 41, and the end face of the contact pin 3 is exposed in the embedding hole 41 to be electrically connected with the abutment portion 22. By arranging the electrolytic sheet pressing block 4, the contact pin 3 is pre-embedded in the electrolytic sheet pressing block 4, and the electrolytic sheet pressing block 4 plays a role of fixing and supporting the contact pin 3, ensuring that the setting position of the contact pin 3 is accurate, and further ensuring that the contact pin 3 and the abutment portion 22 of the electrolytic sheet 2 form a stable electrical connection. At the same time, the electrolytic sheet pressing block 4 can abut against the abutment portion 22 of the electrolytic sheet 2, and can further fix the electrolytic sheet 2, further prevent the electrolytic sheet 2 from displacement or shaking, and ensure the relative position between the electrolytic sheet 2, the fixing frame 1 and the contact pin 3 is stable. In addition, the covering and fixing of the contact pin 3 and the abutment portion 22 by the electrolyte sheet pressing block 4 creates a relatively closed environment for the electrical connection to a certain extent, reduces the erosion 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 electrolyte 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 electrolyte 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 electrolyte sheet 2, without the need for a separate complex positioning operation on the contact pin 3, which improves the assembly efficiency, reduces the assembly difficulty and labor costs, and is also convenient for maintenance.
