In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.
[0034] Additionally, in the following description, specific details are provided to provide a thorough understanding of the examples. However, one skilled in the art will appreciate that the aspects described can be practiced without these specific details.
[0035] 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 6 , a drainage device 8 , a driving mechanism 150 , a walking mechanism 160 and a cleaning brush 170 .
[0036] 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 6 is provided in the flow channel structure 120 to filter the water flowing through the flow channel structure 120. The drainage device 8 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 cleaning brush 170 that can rotate to clean the pool bottom or pool walls, and the drive mechanism 150 is responsible for driving the walking mechanism 160 and the cleaning brush 170 to clean the pool during the walking process.
[0037] In the present application, the shell 110 can be made of plastic and has a cavity inside to accommodate a filtering structure 6 such as a filter screen. The impurities cleaned by the cleaning brush 170 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 8 such as a spiral mechanism, while the impurities and the like are retained in the filter screen to achieve the cleaning operation of the pool.
[0038] Next, refer to Figure 2 , describing the structure of the housing 100 of the pool cleaning robot 100 of the present application.
[0039] like Figure 2As shown, the shell structure of a swimming pool cleaning robot of the present application includes a lower shell 1 of the fuselage, an upper shell 2 of the fuselage, a shell interlayer 3, a water channel cavity 4, a side interlayer inlet and outlet 11, a tail drain port 12, a water inlet 13, a battery compartment window 14, a transparent upper cover 21, a filter structure 6, a battery 5 and a drainage device 8 and other components.
[0040] The lower shell 1 and the upper shell 2 of the fuselage are tightly matched by snapping together, forming a shell interlayer 3 between the two. That is to say, when the lower shell 1 and the upper shell 2 of the fuselage are snapped together, a space is formed between the two, namely the shell interlayer 3.
[0041] like Figure 1 As shown, the top of the upper shell 2 of the fuselage is concave, and the concave part constitutes a water channel cavity 4, which provides space for the internal filtering structure 6 and the drainage device 8, that is, the filtering structure 6 and the drainage device 8 are arranged in the water channel cavity 4.
[0042] Continue to see Figure 2 The side wall of the fuselage lower shell 1 is provided with a side interlayer inlet and outlet 11 for the water inlet and outlet of the shell interlayer 3, ensuring water circulation in the waterway cavity 4. The side interlayer inlet and outlet 11 can be, for example, a rectangular opening provided on the side of the fuselage lower shell 1, and can include one or more.
[0043] The rear side of the lower housing 1 is provided with tail drain ports 12. These tail drain ports 12 are, for example, grid-shaped and arranged longitudinally (vertically), facilitating rapid drainage of water during discharge. Furthermore, a water inlet 13 is provided at the bottom of the lower housing 1 for directing external water into the waterway cavity 4. A battery compartment window 14 is also provided at the bottom for easy installation and removal of the battery 5.
[0044] See also Figure 3 In this application, a transparent cover 21 is installed on the top of the body shell 2. The transparent cover 21 is used to cover the water channel cavity 4 and provide an observation window for checking the internal working conditions. A filter structure 6 is provided inside the water channel cavity 4. The filter structure 6 can be, for example, a filter mesh and can include one or more layers of filter mesh. Figure 4 An example of the filtering structure 6 is shown, which includes a stacked coarse filter mesh and a fine filter mesh, wherein the coarse filter mesh is arranged inside the fine filter mesh to perform preliminary filtration.
[0045] The filter structure 6 aligns with the water inlet 13 of the lower housing 1 through a downwardly protruding opening 41 at its bottom, forming a water inlet channel. Another upwardly protruding opening 42, located above the filter structure 6 and extending beyond its bottom, connects to the downwardly protruding opening 41 below, ensuring unimpeded water flow. This structural design not only ensures that water can enter the waterway cavity 4 smoothly, but also ensures that the filter structure 6 within the waterway cavity 4 can effectively capture impurities.
[0046] In addition, reference Figure 3 In this application, a mounting platform 44 is also provided within the waterway cavity 4 for securing the drainage device 8. This mounting platform 44 ensures that the drainage device 8 is securely mounted, preventing displacement due to vibration or impact during use. Specifically, the drainage device 8 may be, for example, an impeller, and provides negative pressure to cause water to flow through the filter structure 6 and be filtered by the filter structure 6.
[0047] In the present application, when the filter structure 6 is installed in the water channel cavity 4, it has an effective filter area. Specifically, when the filter structure 6 is a filter screen, its effective filter area is the effective area of the filter screen. Generally speaking, the filter screen needs to be fixed by a frame, and the height of the frame connected to the top filter screen defines the top position of the effective filter area of the filter structure 6. For example, Figure 4 In the present invention, the effective filtration area of the filter structure 6 is the position where the filter screen is installed in the frame, and its top position is the highest position where the filter screen is installed in the frame. In the present application, the top position of the effective filtration area of the filter structure 6 needs to be set higher than the height of the mounting platform 44. This is because the water filtered by the filter structure 6 needs to flow to the drain device 8 installed on the mounting platform 44, which also means that the water inlet of the drain device 8 must be at least higher than the position of the mounting platform 44. If the top position of the effective filtration area of the filter structure 6 is lower than the position of the mounting platform 44, an upward flow channel will be formed during the flow of water, that is, it will flow upward from the filter structure 6 to the position of the mounting platform 44 and then enter the drain device 8. This will consume the power of the drain device 8 to lift the water, thereby reducing the efficiency of the robot. Taking this feature into consideration, the applicant set the top position of the effective filtration area of the filter structure 6 higher than the position of the mounting platform 44 during the design. This design ensures that when the water flows into the filtration area, it forms a downward flow channel instead of an upward flow channel when it flows from the filter structure 6 to the drain device 8 on the mounting platform 44, thereby improving the filtration efficiency.
[0048] More specifically, for example, the filter structure 6 can be a single-layer or double-layer filter screen, and the top of the filter screen where the filter screen is effectively filtered is the highest point of the filter screen. If the height of the highest point of the filter screen is lower than the height of the mounting platform 44, it means that in the process of forming the water flow, the water needs to flow upward through the filter screen to the drainage device 8 on the mounting platform 44, thereby forming an upward flow channel, which is not conducive to the discharge of water. Therefore, in the present invention, in order to increase the efficiency of the drainage device 8, the height of the top of the effective filtering area of the filter structure 6 is required to be higher than the height of the mounting platform 44, thereby improving the drainage efficiency.
[0049] In the present application, the lower fuselage shell 1 and the upper fuselage shell 2 can be made of high-strength plastic material, injection-molded by a mold, and fastened with fasteners such as clips or screws. The design of the water channel cavity 4 requires reserving a recessed portion in the mold of the upper fuselage shell 2 to form a complete space. The side interlayer water inlet and outlet 11 can be realized by opening a hole on the side wall of the lower fuselage shell 1. The tail drain outlet 12 can be a drain hole with a filter screen set on the rear side of the lower fuselage shell 1 to block debris. The water inlet 13 and the battery compartment window 14 can also be realized by corresponding openings and sealing treatments.
[0050] The transparent cover 21 is typically made of transparent polycarbonate and is mounted on the top of the upper shell 2 via a hinge or other suitable fastening method. The filter structure 6 can be made of a multi-layer filter screen or porous filter material and is secured within the waterway cavity 4 via a positioning device. The mounting platform 44 can be a raised structure on the inner wall of the upper shell 2, used to support and secure the drainage device 8.
[0051] The shell structure solves the problem of how to effectively take in and drain water when the robot enters and exits the water through the above-mentioned design. Specifically, the side interlayer inlet and outlet 11 and the water inlet 13 of the lower shell 1 of the fuselage respectively ensure that water can smoothly enter the waterway cavity 4 from the outside, be effectively filtered by the filter structure 6, and then be discharged through the drainage device 8. When the robot is out of the water, the water in the shell interlayer 3 can be quickly discharged through the side interlayer inlet and outlet 11, and the water in the waterway cavity 4 can be quickly drained through the tail drain port 12 after being filtered by the filter structure 6, making the entire water circulation process efficient and smooth. This design not only improves the cleaning efficiency of the robot, but also extends the service life of the equipment.
[0052] In one embodiment, a counterweight installation position ( Figure 3This design helps the robot's tail contact the pool bottom first when entering the water and makes it easier to lift its head when climbing walls. By placing the counterweight mounting point at the rear of the lower housing 1, the robot's center of gravity can be effectively adjusted, ensuring stability and maneuverability in different operating modes. Furthermore, the counterweight mounting point is designed for ease of assembly and weight adjustment flexibility, allowing for the robot to adapt to different environments and needs by adding or removing counterweights of varying masses.
[0053] For example, in one specific implementation, the counterweight mounting location can be designed as a groove or raised structure located in a specific area at the rear of the lower fuselage shell 1. This groove or raised structure can accommodate counterweights of varying shapes and weights for easy installation and removal. These counterweights can be connected magnetically or snap-on to prevent them from loosening or falling off during use. Specifically, the counterweights can be made of sheet metal, plastic, or a composite material, with sufficient rigidity and wear resistance to ensure long-term reliability and stability.
[0054] In one embodiment, see Figure 3 The present application discloses a pool cleaning robot housing structure having a bottom scraper bar mounting position 15 at the bottom of the lower housing 1. Specifically, the bottom scraper bar mounting position 15 is disposed in the center area or edge portion of the bottom surface of the lower housing 1, ensuring that the cleaning robot can efficiently remove dirt from the pool bottom while moving. The shape and size of the bottom scraper bar mounting position 15 can be adjusted based on the actual scraper bar size used, ensuring that the scraper bar can be securely installed in this position and will not loosen due to long-term operation. The bottom scraper bar mounting position 15 can be connected to the lower housing 1 through various methods such as threaded connection, snap-on fixing, or bonding, thereby ensuring its stability in various usage environments.
[0055] Specifically, the design of the bottom scraper strip mounting position 15 can be implemented using grooves or protrusions. For example, a transverse or longitudinal groove can be provided on the bottom of the lower housing 1 to insert the fixed end of the scraper strip, which can then be further secured using fasteners or glue. Alternatively, a raised annular structure can be provided on the bottom of the lower housing 1, with threaded holes within the annular structure, to secure the scraper strip in place using screws. Both approaches effectively ensure the stability and reliability of the scraper strip.
[0056] Continue to refer Figure 3In one embodiment, the pool cleaning robot housing structure of the present application has reinforcing ribs 16 on the bottom of the lower housing 1 and side cover mounting areas 17 on the sides. The addition of reinforcing ribs 16 to the bottom of the lower housing 1 not only improves the rigidity and stability of the entire housing but also effectively prevents deformation caused by prolonged immersion in water. The provision of side cover mounting areas 17 facilitates installation and maintenance, allowing users to more easily disassemble, install, or replace relevant internal components.
[0057] For example, in a specific technical implementation, the reinforcing ribs 16 can be integrally manufactured with the lower fuselage shell 1 through injection molding to ensure structural strength and reliability. The side cover mounting locations 17 can be designed as a plurality of positioning protrusions and screw holes distributed on the side of the lower fuselage shell 1, allowing the side cover to be secured thereto via screws or clips. This design not only ensures the stability of the overall structure but also facilitates disassembly and assembly during maintenance and inspection.
[0058] refer to Figure 2 In one embodiment, a float 7 is provided on the front side of the shell interlayer 3 of the shell structure of a pool cleaning robot of the present application. The function of the float 7 is to ensure that the rear side of the pool cleaning robot touches the bottom first when entering the water and to easily raise its head when climbing a wall. The shell interlayer 3 serves as the middle part between the interior and exterior of the robot, and plays a role in protecting internal components and optimizing the external structural design. The provision of the float 7 not only improves the stability of the robot, but also enhances its adaptability to different water environments. The float 7, through its special installation position, enables the robot to maintain a stable posture when entering the water, avoiding damage or instability caused by the front part touching the bottom first.
[0059] For example, in a specific implementation, float 7 can be made of a lightweight material with a certain buoyancy, such as foamed plastic or inflatable material. The shape of float 7 can be elliptical, cylindrical, or other suitable designs, and its specific dimensions can be adjusted based on the overall size of the robot and the required buoyancy. Float 7 can be secured to the front side of the shell interlayer 3 using a snap, adhesive, or other suitable connection method to ensure that it does not loosen or fall off during robot operation. The installation position of float 7 should match the curved surface structure of the front side of the shell interlayer 3 to better achieve the desired functional effect.
[0060] In one embodiment, a one-way drain port 43 is provided at the rear of the water channel cavity 4 of the housing structure of a swimming pool cleaning robot of the present application (see Figure 3), and one-way drain port 43 only allows water to drain outward from the interior of water channel cavity 4. This structure ensures that during robot operation, excess water can be effectively drained through the one-way drain port 43 while preventing external water from flowing back into the interior, keeping the robot dry and operating stably. This design not only optimizes the water circulation path but also avoids the risk of equipment damage caused by accumulated water.
[0061] Specifically, the one-way drain outlet 43 can be implemented by providing an elastic valve. This elastic valve is located at the rear of the water channel cavity 4 and is closed due to negative pressure when the drainage device is operating. When the pressure inside the water channel cavity 4 exceeds the external ambient pressure (for example, when the drainage device stops operating and the robot is lifted out of the water), the water pressure pushes the valve open, allowing water to flow out of the water channel cavity 4. Once the internal pressure decreases or equalizes to the external ambient pressure, the valve recloses, preventing external water from flowing back into the water channel cavity 4. This simple mechanical design ensures the effectiveness and reliability of the one-way drainage function. More specifically, when the drainage device 8 is operating, negative pressure is generated inside the water channel cavity 4, causing the elastic valve to cling to the rear of the water channel cavity 4 and remain closed. Once the drainage device 8 stops operating and water is discharged, the water pressure inside the water channel cavity 4 exceeds the external pressure, causing the elastic valve to open, allowing water to be discharged from the one-way drain outlet 43, achieving rapid drainage.
[0062] In one embodiment, a one-way drain port 43 of the pool cleaning robot housing structure of the present application extends to the bottom of the waterway cavity 4. This design allows the robot to more thoroughly drain water from the waterway cavity 4 during drainage operations, preventing water accumulation or blockage. The one-way drain port 43 not only prevents water from flowing back into the waterway cavity 4 but also improves the robot's operating efficiency and stability.
[0063] In one embodiment, the transparent cover 21 of the pool cleaning robot housing structure of the present application is equipped with an exhaust structure 22 on top, which is used to exhaust air from the waterway cavity 4 when the robot enters the water. This design ensures that the internal and external pressures of the robot can be quickly balanced when entering the water, preventing the formation of air pockets. The transparent cover 21 is typically made of a corrosion-resistant material with a certain degree of light transmittance to enhance aesthetics and visibility during operation. The connection between the transparent cover 21 and the robot housing can adopt a sealing ring, a snap-on connection, or a hinged connection to ensure watertightness.
[0064] The exhaust structure 22 may include one or more exhaust holes and be equipped with an anti-backflow device to prevent water from entering the interior of the robot. These exhaust holes are usually distributed at the highest point of the transparent upper cover 21 to facilitate the smooth discharge of air. The anti-backflow device can be a one-way valve or a diaphragm valve, which realizes one-way gas flow through mechanical principles. When the robot leaves the water surface, these anti-backflow devices can effectively prevent external moisture from entering the interior of the robot, ensuring the safety of internal circuits and equipment. The specific position and design of the exhaust structure 22 need to be optimized according to the shape and size of the entire robot to ensure optimal working performance.
[0065] In one embodiment, the exhaust structure 22 can be implemented as a set of miniature one-way valves mounted at the apex of the transparent upper cover 21. When the robot enters water, the water pressure causes these one-way valves to open, allowing air to be rapidly expelled through the exhaust holes. At the same time, these one-way valves remain closed under normal circumstances, preventing water from entering the robot's interior.
[0066] In addition, in the present application, the inventor took into consideration that when the user is holding the robot, the transparent cover 21 may be squeezed by the arms, which may cause the transparent cover 21 to open and the water channel cavity to be opened. Therefore, in the present application, the transparent cover 21 is engaged with the upper shell 2 of the body through a vertical hook structure. In this way, when the transparent cover 21 is subjected to an upward force in the vertical direction, the vertical hook structure is used to resist the pulling force in the vertical direction, thereby preventing the transparent cover 21 from being opened and exposing the water channel cavity 4 and causing personal safety risks.
[0067] Specifically, if Figure 5 As shown, a recess 23 can be provided on the side of the upper shell 2 of the fuselage away from the installation portion of the transparent upper cover 21. The recess 23 can be two or more symmetrical recesses, and the top can be set at an angle inclined downward. On the other hand, as shown in FIG. Figure 6 As shown, a vertical hook 24 can be provided at a position corresponding to the transparent upper cover 21. The direction of the hook 24 is upward to abut against the top of the recess 23 to prevent the vertical upward force from directly opening the transparent upper cover 21. When the transparent upper cover 21 is installed in place, the vertical hook 24 is engaged with the recess 23. Figure 7 The vertical hook 24 is shown to be engaged with the recess 23. At this time, a lateral force is required to slightly deform the transparent cover 21 to remove the hook 24 from the recess 23. This prevents the transparent cover 21 from being accidentally opened when the user is holding the robot.
[0068] During actual operation, when this device is in use, the pool cleaning robot's housing structure achieves efficient cleaning and maintenance functions through the coordinated operation of multiple key components. First, the robot's lower housing 1 and upper housing 2 snap together to form a housing interlayer 3, ensuring the sealing and stability of the entire housing structure. Simultaneously, a recessed portion of the upper housing 2 forms a water channel cavity 4, which not only provides a path for water circulation but also houses the core filtration device.
[0069] Before starting the cleaning work, the battery 5 is installed in the shell interlayer 3 through the battery compartment window 14 to provide the necessary power for the robot. When the robot is started, water flows into the water channel cavity 4 from the upward protruding opening 42 of the upper shell 2 of the fuselage, and passes through the filter structure 6 located in the water channel cavity 4. The design of the filter structure 6 requires that the water must first pass through a filter mesh or filter cotton and other materials to remove dirt and impurities in the water. The filtered water continues to flow to the downward protruding opening 41 at the bottom of the water channel cavity 4, and then is discharged through the side interlayer water inlet and outlet 11 formed at the junction of the upper shell 2 and the lower shell 1 of the fuselage, achieving a preliminary cleaning effect. At the same time, the water inlet 13 at the bottom of the body is responsible for introducing new water sources to be treated to ensure that clean water always flows through the water channel cavity 4.
[0070] In order to further improve the cleaning efficiency, the drainage device 8 installed in the water channel cavity 4 is placed on a dedicated mounting platform 44. The device can be quickly started after cleaning is completed, and the accumulated water is efficiently discharged through the tail drain 12, reducing the secondary pollution or corrosion problems caused by residual water when the robot is not working. It is worth noting that the effective filtration area of the filter structure 6 is higher than the mounting platform 44, which ensures that the filter structure 6 will not cause pollutant leakage due to uneven water pressure, thereby ensuring the purity of the outlet water quality and the overall operation effect of the robot. The whole process reflects that the designer fully considered the needs of functionality and durability while taking into account practicality and aesthetics.
