[0025] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0026] First, refer to Figure 1 , describes the overall structure of the swimming pool cleaning robot 100 of the present application. Figure 1 As shown, the swimming pool cleaning robot of the present application includes a housing 110 , a flow channel structure 120 , a filtering structure 130 , a drainage device 140 , a driving mechanism 150 , a walking mechanism 160 and a roller brush 170 .

[0027] The housing 110 is the main structure of the pool cleaning robot, and is internally provided with a flow channel structure 120. The flow channel structure 120 is a water flow channel, and a filter structure 130 is provided in the flow channel structure 120 to filter the water flowing through the flow channel structure 120. The drainage device 140 is also provided in the flow channel structure 120 and provides power to discharge the filtered water out of the flow channel structure 120, thereby filtering the water in the pool. The pool cleaning robot of the present application is provided with a roller brush 170, which can rotate to clean the bottom or walls of the pool, and the drive mechanism 150 is responsible for driving the walking mechanism 160 and the roller brush 170 to clean the pool while walking.

[0028] In the present application, the shell 110 can be made of plastic and has a cavity inside to accommodate a filtering structure 130 such as a filter screen. Impurities cleaned by the roller brush 170 (not shown) enter the flow channel structure 120 through, for example, a water inlet at the bottom of the pool cleaning robot, and are then filtered through the filter screen. The filtered water is then discharged from the top of the pool cleaning robot 100 using a drainage device 140 such as a spiral mechanism, while impurities and the like are retained in the filter screen to achieve the cleaning operation of the pool.

[0029] Next, refer to Figure 2 , specifically describing the filtering structure 130 of the present application, the filtering structure 130 is a double-layer filter screen filtering system, and the double-layer filter screen filtering system includes a fine filter screen frame 1 and a coarse filter screen frame 2.

[0030] Specifically, the fine filter frame 1 is stacked outside the coarse filter frame 2. The filtration accuracy of the fine filter frame 1 is higher than that of the coarse filter frame 2, ensuring a multi-layered and multi-level filtration effect. In another embodiment, the fine filter frame 1 can partially or completely surround the coarse filter frame 2, that is, the fine filter frame 1 at least partially surrounds the coarse filter frame 2.

[0031] In the application, the bottom of the fine filter frame 1 is provided with an opening 11, and the corresponding position of the coarse filter frame 2 is provided with a water inlet 21. The water inlet 21 protrudes into the interior of the coarse filter frame 2 to better guide the water flow into the coarse filter frame 2. In addition, a water inlet baffle 22 is provided on the top of the water inlet 21, which can automatically close when there is no water flow to prevent the backflow of external impurities.

[0032] Specifically, the opening 11 at the bottom of the fine filter frame 1 is an opening for water to enter, which is, for example, rectangular and is arranged at the bottom of the fine filter frame 1. Since the filter structure 130 of the present application adopts a filter structure, a water inlet 21 is provided at the corresponding position of the coarse filter frame 2. When the fine filter frame 1 and the coarse filter frame 2 are installed in place, the opening 11 overlaps with the water inlet 21, so that water enters the coarse filter frame 2 through the water inlet 21, thereby performing double-layer filtration. In addition, in order to prevent impurities in the fine filter frame 1 from flowing back out of the water inlet 21 during the water discharge process (for example, entering a shallow area or artificially raising the water surface), a water inlet baffle 22 is provided on the top of the water inlet 21 of the present application (see Figure 3 ) to prevent water from flowing out through the water inlet 21.

[0033] In the present application, the water inlet baffle 22 is arranged so that it automatically closes when there is no water flow. Specifically, the water inlet baffle 22 can be hinged to the top of the water inlet 21, and the width of one side of the opening exceeds the width of the opening of the water inlet 21. Therefore, when there is no water flow, the water inlet baffle 22 can completely cover the top of the water inlet 21, so that even if there is water in the coarse filter frame 2, it will not flow out of the water inlet 21.

[0034] Specifically, if Figure 3 As shown, one side of the water inlet baffle 22 can be hinged to the top side of the water inlet 21, so that when the water is sucked by the drainage device 140, the water pushes the water inlet baffle 22 upward from the water inlet 21 to allow the water to enter the coarse filter frame 2. In the present application, the water inlet baffle 22 can be made of a soft material such as rubber, and when the power is turned off, the water inlet baffle 22 closes the water inlet 21 due to the action of gravity.

[0035] In addition, in the present application, the water inlet 21 is not set in the middle of the coarse filter frame 2, but closer to one side thereof. Specifically, in the present application, the water inlet 21 is set closer to the position of the roller brush 170. More specifically, the water inlet 21 is set closer to the position of the drainage device 140. This can reduce the flow of water, thereby increasing the suction force to more effectively filter impurities in the water. Specifically, for example, when the roller brush 170 is set at the bottom of the front side of the robot 100, the water inlet 21 is set closer to the front side of the coarse filter frame 2. At this time, the drainage device 140 is also set close to the front side of the robot 100. This can reduce the overall flow, thereby better utilizing the drainage device 140. That is to say, in the present application, the roller brush 170 and the drainage device 140 are set on the same side relative to the filter structure 130, and the water inlet 21 is set on the side of the coarse filter frame 2 close to the roller brush 170 and the drainage device 140, thereby improving the drainage efficiency of the robot 100.

[0036] In this case, from the perspective of reducing water flow, the opening direction of the water inlet baffle 22 should also be toward the side of the roller brush 170 and the drainage device 140, thus forming a smoother flow path. However, in contrast, in the present application, the water inlet baffle 22 is arranged in the opposite direction. Specifically, it is arranged to open toward the rear of the robot 100, that is, toward the side of the coarse filter frame 2 with a larger distance. For example, when the drainage device 140 is arranged at the front end of the robot relative to the filtering structure, the water inlet 21 is arranged closer to the front end in the coarse filter frame 2 and farther away from the rear end. In this case, the opening of the water inlet baffle 22 is toward the rear end. This is because when the robot is out of the water or walking to the foreshore, the robot will tilt, and the tilted body will more easily close the water inlet baffle 22 toward the rear end, thereby preventing water from flowing out of the robot through the water inlet baffle 22 without being filtered. If it is opened toward the front end, impurities and the like may flow out of the water inlet 21 due to gravity.

[0037] In this application, the fine filter frame 1 and coarse filter frame 2 in the filtration structure can be made of filter materials with different pore sizes. The filtration pore size of the fine filter frame 1 is smaller than that of the coarse filter frame 2. The opening 11 at the bottom of the fine filter frame 1 is manufactured using cutting technology to ensure docking with the water inlet 21 of the coarse filter frame 2. The protruding design of the water inlet 21 allows water to flow smoothly into the coarse filter frame 2. The water inlet baffle 22 is made of elastic material and can be opened and closed freely under the action of external force and automatically closes when there is no water flow.

[0038] This filtration structure solves the problem of effectively filtering impurities of varying particle sizes in swimming pools through a multi-layered filtration structure. Specifically, the coarse filter frame 2 first intercepts large particles of debris, preventing these large particles from directly entering the fine filter frame 1 and causing blockage. The high filtration accuracy of the fine filter frame 1 further removes tiny particles and suspended solids from the water, ensuring clean water quality. In addition, the design of the water inlet baffle 22 allows the entire filtration system to effectively prevent the backflow of filtered water when it stops operating, thereby avoiding secondary contamination and improving the operating efficiency and cleaning effect of the entire system. In this way, the filtration system significantly improves the effectiveness of the pool cleaning robot in purifying pool water.

[0039] In one embodiment, Figure 4 As shown, the fine filter frame 1 and coarse filter frame 2 of the pool cleaning robot filtration structure of the present application both utilize a frame structure design. These frames not only provide support but also ensure that the filter 3 can be effectively installed and maintain its shape and strength. The frame design of the fine filter frame 1 and the coarse filter frame 2 ensures stability and durability during the cleaning process. In addition, the filter 3 is arranged between these frames, forming a multi-layered filtration structure. This double-layer design enables efficient filtration of pool water at different stages, ensuring water quality.

[0040] Specifically, the fine filter frame 1 and the coarse filter frame 2 are made of metal or high-strength plastic, respectively, to ensure sufficient mechanical strength and corrosion resistance. The frame is usually rectangular or circular, and forms a plurality of filter intervals. The filter 3 is arranged in these filter intervals, and the specific shape can be adjusted according to the actual size and needs of the robot. The filter 3 is fixed between the frames and can be reliably connected by snaps, screws or other fasteners such as glue. For example, a plurality of grooves or protrusions can be provided on the inner side of the frame to accommodate and fix the filter 3 to ensure that it will not loosen or fall off during operation. Specifically, the spacing between the fine filter and the coarse filter can be set to 2-7 mm, for example, so as to achieve effective filtering between different levels, thereby achieving the best filtering effect.

[0041] In one embodiment, a frame structure of a pool cleaning robot filter structure of the present application is provided with a raised structure at the bottom, which is used for draining water, thereby ensuring that the filter system has space for draining water in both working and non-working states. For example, a raised structure can be provided at the bottom of the coarse filter frame 2, so that when the coarse filter frame 2 is installed inside the fine filter frame 1, a certain gap is formed between the two, which can facilitate the filtering of water from the coarse filter frame 2. Specifically, the raised structures can be evenly distributed at the bottom of the entire frame structure, and their height can be adjusted according to the needs of actual application. The design of these raised structures can not only improve the overall stability of the filtration system, but also effectively prevent water from accumulating at the bottom of the frame structure, reducing the breeding of bacteria and other microorganisms.

[0042] For example, the bottom of the frame with a raised structure can be manufactured by injection molding. These raised structures can be designed as multiple evenly arranged cylindrical protrusions or grid-like ridges to ensure that they form an integrated structure with the other parts of the frame structure, thereby ensuring strength while also increasing its reliability and durability in practical applications. Specifically, the height of the protrusion can be determined based on the characteristics of the actual filter 3 material and the desired drainage effect, usually between 1 and 5 mm. This design not only effectively achieves the drainage function, but also allows for easy disassembly and cleaning, further improving the maintainability and service life of the system.

[0043] like Figure 3 As shown, in one embodiment, a filter 3 of a pool cleaning robot filtration structure of the present application is installed on the surrounding sidewalls and bottom rear sides of the fine filter frame 1 and the coarse filter frame 2. Specifically, the installation position of the filter 3 not only covers the side between the coarse filter frame 2 and the fine filter frame 1, but also extends to the bottom rear side of them, which is located on the side facing the water inlet baffle 22. This arrangement ensures that water flows through multiple layers of filtration, improving the overall cleaning efficiency of the filter 3. More specifically, since the rear portions of the coarse filter frame 2 and the fine filter frame 1 will be at a lower position during the robot's discharge process, whether carried by hand or gradually walking to the foreshore area, the installation of the filter 3 at the bottom rear of the coarse filter frame 2 and the fine filter frame 1 can further enhance drainage performance. In this case, since the water inlet 21 is located near the front end, sufficient space is left for the filter 3 at the bottom rear end.

[0044] In one embodiment, Figure 2As shown, the fine filter frame 1 and the coarse filter frame 2 of the pool cleaning robot filtration structure of the present application both feature top openings. This design allows the user to observe the blockage status of the filter 3, allowing for timely cleaning and maintenance. Specifically, the fine filter frame 1 and the coarse filter frame 2 each have top openings, and these openings facilitate regular inspections. The opening design not only improves maintenance convenience but also allows for intuitive inspection of the working status of the filter 3 without disassembling the entire filtration system.

[0045] In one embodiment, Figure 4 As shown, the top opening edge of the coarse filter frame 2 of the pool cleaning robot filtration structure of the present application is provided with a sealing ring 23, which is designed to tightly fit the top transparent cover of the robot 100. This design effectively prevents trapped particulate matter from leaking through the gap between the coarse filter frame 2 and the cover during operation of the filter 3, thereby maintaining the cleanliness of the machine interior. The design of the sealing ring 23 not only improves the system's sealing performance but also ensures the efficient operation of the filtration system.

[0046] In actual applications, the sealing ring 23 is installed on the top edge of the coarse filter frame 2, forming a complete annular structure around the entire top opening. Specifically, the sealing ring 23 can be made of a flexible material, such as silicone or rubber, to ensure that it can provide a good sealing effect when in contact with the top transparent cover. For example, the sealing ring 23 can be fixed to the top edge of the coarse filter frame 2 by bonding or embedding. In addition, the top transparent cover is designed to have a shape and size that fits closely with the sealing ring 23, thereby ensuring that the sealing ring 23 can achieve the best sealing effect when the cover is closed. This installation method is simple and reliable, and is easy to produce and maintain.

[0047] In one embodiment, in a filtering structure of a swimming pool cleaning robot filtering structure of the present application, the fine filter frame 1 and the coarse filter frame 2 are fixed by snaps (see Figure 2 The clips on the side of the medium and fine filter frame 1). This fastening method not only ensures a secure connection between the two filter frames 3 during cleaning, but also facilitates removal and replacement. The dimensions of the fine filter frame 1 and the coarse filter frame 2 are designed to fit perfectly together, ensuring smooth water flow during filtration without leaking unfiltered waste.

[0048] In one embodiment, the fine filter frame 1 and the coarse filter frame 2 are fixedly connected via a snap-fit ​​structure. The snap-fit ​​is typically located at the edge of the fine filter frame 1 and matches the corresponding position of the coarse filter frame 2. When the coarse filter frame 2 is inserted into the fine filter frame 1, the snap-fit ​​automatically snaps together, tightly connecting the two. During disassembly, the snap-fit ​​can be released by manually applying a certain amount of force, making it convenient for the user to clean or replace the filter 3. This snap-fit ​​structure is simple and reliable, and can effectively prevent the coarse filter frame 2 from detaching from the fine filter frame 1 due to water pressure or other external forces during operation.

[0049] See also Figure 2 In one embodiment, the coarse filter frame 2 in the pool cleaning robot filtration structure of the present application is provided with a handle 24 on the side and a positioning device 25 on the outside to facilitate installation. The provision of the handle 24 makes it more convenient for the operator to install or replace the coarse filter frame 2. The coarse filter frame 2 can be easily removed or inserted by simply lifting the handle 24. The design of the positioning device 25 ensures that the coarse filter frame 2 can be accurately positioned during installation, ensuring that the coarse filter frame 2 is aligned with the fine filter frame 1.

[0050] Specifically, the handle 24 can be made of a corrosion-resistant material and securely fastened to the side of the coarse screen frame 2, making it easy for the operator to grip. The positioning device 25 can be one or more protrusions in the shape of a herringbone, hook, or other shape, secured to appropriate locations on the outside to mate with corresponding grooves or notches on the fine screen frame 1 during installation. For example, the positioning device 25 can be a plastic part with a barbed structure, embedded in the outside of the coarse screen frame 2. During installation, it mates with the grooves on the fine screen frame 1, ensuring that the coarse screen frame 2 is securely and correctly installed.

[0051] In one embodiment, the filtration structure of a pool cleaning robot of the present application includes a protruding water inlet 21 with a height of no less than 2 cm. The unique design of the water inlet 21 is that the shape and size of its protruding portion can effectively increase the initial kinetic energy of the water entering the filtration system, thereby improving the efficiency of the subsequent filtration process. The water inlet 21 is usually located at the front end of the filtration system. Its protruding design helps to guide the pool water to the internal double-layer filter system, ensuring that the pool water flows smoothly and is filtered through the primary and secondary filters. In addition, by providing a water inlet 21 of at least 2 cm, heavier materials such as gravel can be deposited around it.

[0052] In one embodiment, a filtration structure of a pool cleaning robot of the present application includes a fine filter frame 1 and a coarse filter frame 2. The fine filter frame 1 and the coarse filter frame 2 each have an effective filtration area. Specifically, the area of ​​the fine filter frame 1 and the coarse filter frame 2 where the filter 3 is provided is the effective filtration area of ​​the two. In the present application, the height of the effective filtering area of ​​the fine filter frame 1 is higher than the height of the effective filtering area of ​​the coarse filter frame 2. This design is mainly considered to improve the filtering capacity and reduce the clogging of impurities. More specifically, since the fine filter frame 1 is arranged on the outside of the coarse filter frame 2, and the two actually form a connecting mechanism through the filter 3, and in order to filter the impurities floating on the top, the top area of ​​the coarse filter frame 2 is generally set as a plastic frame, and the impurities are blocked by the frame. At this time, water cannot pass through here to reach the drainage device 140. If the effective filtering height of the fine filter frame 1 is lower than the height of the effective filtering area of ​​the coarse filter frame 2, the water has to enter the drainage device 140 from a lower position, thereby forming an ascending flow channel, which requires additional power consumption and is not conducive to water discharge. Therefore, in the present application, by making the height of the effective filtering area of ​​the fine filter frame 1 higher than the height of the effective filtering area of ​​the coarse filter frame 2, a descending flow channel is formed between the fine filter frame 1 and the drainage device 140 as much as possible or the distance of the ascending flow channel is reduced as much as possible, thereby enhancing the filtering effect.

[0053] During actual operation, when this device is in use, the robot absorbs impurities and dirt in the water through the water inlet located at the bottom of the shell during its movement. These water flows are guided to the filtration structure through the flow channel structure, specifically a double-layer filter system consisting of a coarse filter frame 2 and a fine filter frame 1 arranged from the inside to the outside. In the process of water flowing through the coarse filter frame 2, larger particles of impurities such as leaves and larger dirt are filtered out first, reducing the pressure of subsequent processing. Then, the water flow after preliminary filtration enters the fine filter frame 1, where the filtration accuracy is higher, and it can further intercept finer suspended particles and dirt, ensuring a higher degree of water cleanliness.

[0054] To ensure the stability and continuity of the system's operation, the unique design of the double-layer filter frame 3 plays a key role. The fine filter frame 1 features an opening 11 at its bottom, while the corresponding coarse filter frame 2 has a protruding water inlet 21. Atop this, an automatically opening and closing inlet flap 22 is installed. When water enters, flap 22 is pushed open, allowing water to flow smoothly through inlet 21 into the filtration system. If water stops flowing, flap 22 automatically resets and closes, preventing foreign matter from entering the system and ensuring a clean and efficient filtration system.

[0055] Finally, after being filtered through the double-layer filter system, the clean water is discharged through the outlet under the negative pressure generated by the drainage device and returned to the pool, completing the water circulation and purification process. Simultaneously, the robot's built-in drive mechanism provides power to drive the walking mechanism and cleaning brush, enabling the robot to move freely along the pool bottom and walls, coordinating with the water flow to achieve comprehensive cleaning. Throughout the entire process, each component coordinates and operates efficiently, ensuring that the pool remains clear and clean at all times.
