[0033] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present disclosure. The drawings only show components related to the present disclosure rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0034] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects described may 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 swimming pool cleaning robot, and a flow channel structure 120 is arranged inside the housing. The flow channel structure 120 is a water flow channel for water to flow. A filter structure 6 is arranged in the flow channel structure 120 to filter the water flowing through the flow channel structure 120, wherein the drainage device 8 is also arranged 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 swimming pool. The swimming pool cleaning robot of the present application is provided with a cleaning brush 170, which can rotate to clean the bottom or wall of the pool, and the driving mechanism 150 is responsible for driving the walking mechanism 160 and the cleaning brush 170 to clean the swimming pool during walking.

[0037] In the present application, the shell 110 can be made of plastic, and a cavity is set inside to accommodate a filtering structure 6 such as a filter net. 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 swimming pool cleaning robot, and then filtered through the filter net, so that the filtered water is discharged from the top of the swimming pool cleaning robot 100 by a drainage device 8 such as a spiral mechanism, while the impurities and the like are retained in the filter net to achieve the cleaning operation of the swimming pool.

[0038] Next, refer to Figure 2 , describing the structure of the housing 100 of the swimming pool cleaning robot 100 of the present application.

[0039] like Figure 2As shown, a 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 waterway cavity 4, a side interlayer inlet and outlet 11, a tail outlet 12, a water inlet 13, a battery compartment window 14, a transparent upper cover 21, a filtering structure 6, a battery 5, a drainage device 8 and other components.

[0040] The lower shell 1 of the fuselage and the upper shell 2 of the fuselage are tightly matched by buckling, and a shell sandwich 3 is formed between the two. That is to say, when the lower shell 1 of the fuselage and the upper shell 2 of the fuselage are buckled together, a space, namely the shell sandwich 3, is formed between the two.

[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 sandwich inlet and outlet 11 for water inlet and outlet of the shell sandwich 3 to ensure water circulation in the waterway cavity 4. The side sandwich 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] A tail drain port 12 is provided on the rear side of the lower shell 1 of the fuselage. The tail drain ports 12 are, for example, grid-shaped and arranged in the longitudinal direction (vertical direction) to facilitate rapid drainage when the water is discharged. In addition, a water inlet 13 is provided at the bottom of the lower shell 1 of the fuselage to guide the external water source into the waterway cavity 4. At the same time, a battery compartment window 14 is also provided at the bottom to facilitate the installation and removal of the battery 5.

[0044] See also Figure 3 In the present application, a transparent cover 21 is installed on the top of the fuselage shell 2, and the transparent cover 21 is used to cover the water channel cavity 4, and provides an observation window for checking the internal working conditions. A filter structure 6 is arranged inside the water channel cavity 4, and the filter structure 6 can be a filter net, and can include one or more layers of filter nets. Figure 4 An example of a 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 for preliminary filtering.

[0045] The filter structure 6 is aligned with the water inlet 13 of the lower shell 1 of the fuselage through a downwardly protruding opening 41 at the bottom thereof, forming a water inlet channel. Another upwardly protruding opening 42 is located above the filter structure 6 and extends beyond the bottom of the filter structure 6 to communicate with the downwardly protruding opening 41 below, ensuring unimpeded water flow. This structural design not only ensures that water can smoothly enter the waterway cavity 4, but also ensures that the filter structure 6 in the waterway cavity 4 can effectively capture impurities.

[0046] In addition, reference Figure 3 In the present application, a mounting platform 44 for fixing the drainage device 8 is also provided in the water channel cavity 4. The mounting platform 44 ensures that the drainage device 8 is firmly installed to avoid displacement due to vibration or impact during use. Specifically, the drainage device 8 can be, for example, an impeller, and provides negative pressure to make water 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 application, the effective filtering area of ​​the filtering structure 6 is the position of the filter screen installed in the frame, and its top position is the highest position of the filter screen installed in the frame. In the present application, it is necessary to set the top position of the effective filtering area of ​​the filtering structure 6 higher than the height of the mounting platform 44, because the water filtered by the filtering structure 6 needs to flow to the drainage device 8 installed on the mounting platform 44, which also means that the water inlet of the drainage device 8 will be at least higher than the position of the mounting platform 44. If the top position of the effective filtering area of ​​the filtering structure 6 is lower than the position of the mounting platform 44, an ascending flow channel will be formed during the flow of water, that is, it will flow upward from the filtering structure 6 to the position of the mounting platform 44 and then enter the drainage device 8, which will consume the power of the drainage device 8 to lift water, thereby reducing the efficiency of the robot. Taking this feature into consideration, the applicant sets the top position of the effective filtering area of ​​the filtering structure 6 higher than the position of the mounting platform 44 during the design. This design ensures that when the water flows into the filtering area, when the water flows from the filtering structure 6 to the drainage device 8 at the mounting platform 44, a downward flow channel is formed instead of an upward flow channel, thereby improving the efficiency of the filtration.

[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 effective filtering is performed 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 a water flow, 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 water discharge. 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 fuselage lower shell 1 and the fuselage upper shell 2 can be made of high-strength plastic material, molded by mold injection, and fastened with fasteners such as snaps or screws. The design of the water channel cavity 4 requires reserving a recessed portion in the mold of the fuselage upper 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 fuselage lower shell 1. The tail drain outlet 12 can be provided with a drain hole with a filter on the rear side of the fuselage lower 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 upper cover 21 is usually made of transparent polycarbonate material and is mounted on the top of the upper shell 2 of the fuselage by hinges or other suitable fixing methods. The filter structure 6 can be made of a multi-layer filter screen or a porous filter material and fixed in the water channel cavity 4 by a positioning device. The mounting platform 44 can be a protruding structure on the inner wall of the upper shell 2 of the fuselage, which is used to support and fix 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, and after being effectively filtered by the filter structure 6, it is discharged through the drainage device 8. When the robot is out of 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 3The convex part of the middle tail) is designed to help the tail touch the bottom of the pool first when entering the water, and to make it easier to raise the head when climbing the wall. By setting the counterweight installation position at the tail of the lower shell 1 of the fuselage, the center of gravity distribution of the robot can be effectively adjusted to ensure its stability and maneuverability in different operation modes. In addition, the design of the counterweight installation position takes into account the convenience of assembly and the flexibility of weight adjustment, and can adapt to different usage environments and needs by adding or removing counterweight blocks of different masses.

[0053] For example, in a specific implementation, the counterweight installation position can be designed as a groove or a protrusion structure, located in a specific area at the rear of the lower shell 1 of the fuselage. The groove or protrusion structure can match the counterweight blocks of different shapes and masses to facilitate installation and removal. These counterweight blocks can be connected by magnetic suction or snap-on connection to ensure that they will not loosen or fall off during use. Specifically, the counterweight block can be made of metal plate, plastic or composite material, with sufficient rigidity and wear resistance to ensure reliability and stability for long-term use.

[0054] In one embodiment, see Figure 3 The present application discloses a swimming pool cleaning robot shell structure, wherein a bottom scraper bar installation position 15 is provided at the bottom of the lower body shell 1. Specifically, the bottom scraper bar installation position 15 is arranged at the center area or edge portion of the bottom surface of the lower body shell 1, so as to ensure that the cleaning robot can efficiently remove dirt from the bottom surface of the swimming pool when moving. The shape and size design of the bottom scraper bar installation position 15 can be adjusted according to the size of the scraper bar actually used, so as to ensure that the scraper bar can be firmly installed in this position and will not loosen due to long-term work. The bottom scraper bar installation position 15 can be connected to the lower body shell 1 by various means such as threaded connection, snap-on fixing or bonding, so as to ensure its stability in various use environments.

[0055] Specifically, the design of the bottom scraper strip installation position 15 can be realized by slotting or protrusions. For example, a horizontal or vertical groove structure can be opened at the bottom of the fuselage lower shell 1 for inserting the fixed end of the scraper strip, and then further fixed by fasteners or glue. In addition, a raised annular structure can be set at the bottom of the fuselage lower shell 1, and a threaded hole is set inside the annular structure, and the scraper strip is fixed at this position by screwing in screws. Both methods can effectively ensure the stability and reliability of the scraper strip.

[0056] Continue to refer Figure 3In one embodiment, a lower housing 1 of a pool cleaning robot housing structure of the present application is provided with reinforcing ribs 16 at the bottom and side cover mounting positions 17 at the sides. By adding reinforcing ribs 16 at the bottom of the lower housing 1, not only can the rigidity and stability of the entire housing be improved, but also deformation problems caused by long-term immersion in water can be effectively prevented. The provision of the side cover mounting position 17 provides a convenient installation and maintenance method, allowing users to more conveniently disassemble or replace related internal components.

[0057] For example, in a specific technical implementation, the reinforcing rib 16 can be manufactured integrally with the fuselage lower shell 1 by injection molding to ensure its structural strength and reliability. The side cover mounting position 17 can be designed as a plurality of positioning protrusions and screw holes distributed on the side of the fuselage lower shell 1 so that the side cover can be fixed thereon by screws or buckles. Such a design not only ensures the stability of the overall structure, but also facilitates the disassembly and assembly operations during maintenance and inspection.

[0058] refer to Figure 3 In one embodiment, a float 7 is provided on the front side of the shell interlayer 3 of a shell structure of a swimming pool cleaning robot of the present application. The function of the float 7 is to ensure that the rear side of the swimming 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, as the middle part between the inside and the outside of the robot, plays a role in protecting the internal components and optimizing the external structure design. The setting of the float 7 not only improves the stability of the robot, but also enhances its adaptability in 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 the specific implementation process, the float 7 can be made of a lightweight material with a certain buoyancy, such as foamed plastic or inflatable material. The shape of the float 7 can be elliptical, cylindrical or other suitable designs, and its specific size is adjusted according to the overall size of the robot and the required buoyancy. The float 7 can be fixed to the front side of the shell interlayer 3 by snaps, adhesives or other suitable connection methods to ensure that it will not loosen or fall off during the operation of the robot. The installation position of the float 7 should match the curved surface structure on the front side of the shell interlayer 3 so as to better achieve the expected 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), the one-way drain port 43 only allows water to be discharged from the inside of the water channel cavity 4 to the outside. This structure ensures that during the operation of the robot, excess water can be effectively discharged through the one-way drain port 43, while preventing external water from flowing back into the inside, keeping the robot dry and working stably. Through such a design, not only the water circulation path is optimized, but also the risk of equipment damage caused by water accumulation is avoided.

[0061] Specifically, the one-way drain port 43 can be realized by setting an elastic valve. The elastic valve is located at the rear of the water channel cavity 4, and is in a closed state due to negative pressure when the drainage device is working. When the pressure in the water channel cavity 4 is greater than the external environmental pressure (for example, when the drainage device stops working and the robot is lifted out of the water), the water pressure will push the valve to open, so that the water can flow out from the inside of the water channel cavity 4. Once the internal pressure decreases or is equal to the external environmental pressure, the valve will close again to prevent the 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 working, a negative pressure is formed inside the water channel cavity 4, so that the elastic valve is close to the rear of the water channel cavity 4 and is in a closed state. Once the drainage device 8 stops working and discharges water, the water pressure in the water channel cavity 4 is greater than the external pressure, and the elastic valve opens, so that water is discharged from the one-way drain port 43 to achieve rapid drainage.

[0062] In one embodiment, the one-way drain port 43 of the housing structure of a swimming pool cleaning robot of the present application extends to the bottom of the water channel cavity 4. This design enables the robot to more thoroughly drain the water in the water channel cavity 4 when performing a drainage operation, thereby avoiding water accumulation or blockage. The design of the one-way drain port 43 can not only prevent the water from flowing back into the water channel cavity 4, but also improve the working efficiency and stability of the robot.

[0063] In one embodiment, a transparent upper cover 21 of a shell structure of a pool cleaning robot of the present application is provided with an exhaust structure 22 on the top thereof, which is used to exhaust the air in the waterway cavity 4 when the robot enters the water. This design ensures that the robot can quickly balance the internal and external pressures when entering the water to prevent the formation of air pockets inside. The transparent upper cover 21 is usually made of a corrosion-resistant material with a certain degree of light transmittance to enhance the aesthetics and visibility during operation. The connection between the transparent upper cover 21 and the robot shell can be a sealing ring, a snap-on or a hinged connection to ensure water tightness.

[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 the best working performance.

[0065] In one embodiment, the exhaust structure 22 can be specifically implemented as a group of micro one-way valves installed at the apex of the transparent upper cover 21. When the robot enters the water, the water pressure will open these one-way valves, and the air will be quickly exhausted through the exhaust holes. At the same time, these one-way valves remain closed under normal circumstances to prevent water from entering the internal space of the robot.

[0066] In addition, in the present application, the inventor took into consideration that when the user is holding the robot, the transparent upper cover 21 may be opened and the water channel cavity may be opened due to the squeezing of the transparent upper cover 21 by the arms. Therefore, in the present application, the transparent upper cover 21 is engaged with the upper shell 2 of the body via a vertical inverted hook structure. In this way, when the transparent upper cover 21 is subjected to an upward force in the vertical direction, the vertical inverted hook structure is used to resist the pulling force in the vertical direction, thereby preventing the transparent upper cover 21 from being opened and exposing the water channel cavity 4.

[0067] Specifically, Figure 5 As shown, a recess 23 can be provided on one 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, and 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, and 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. In this way, the transparent cover 21 is prevented from being accidentally opened when the user is holding the robot.

[0068] In actual operation, when the device is used, the shell structure of the pool cleaning robot achieves efficient cleaning and maintenance functions through the coordinated work of multiple key components. First, the lower shell 1 of the robot body is buckled with the upper shell 2 of the body to form a shell sandwich 3, which ensures the sealing and stability of the entire shell structure. At the same time, the concave part of the upper shell 2 of the body forms a water channel cavity 4, which not only provides a path for water circulation, but also accommodates the core filtering 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, the water flows in from the upward protruding opening 42 of the water channel cavity 4 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 net 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 of the fuselage 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 can be efficiently discharged using the tail drain port 12, reducing the secondary pollution or corrosion 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 leak pollutants 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 considers the needs of functionality and durability while taking into account practicality and aesthetics.
