[0030] It is also necessary to note that the drawings provided in the following embodiments only illustrate the basic concept of the present disclosure in a schematic manner, and only show the components related to the present disclosure in the drawings, not drawn according to the number, shape and size of the components when actually implemented, and the type, number and proportion of each component when actually implemented can be a random change, and the component layout type can also be more complex.

[0031] In addition, in the following description, specific details are provided in order to facilitate a thorough understanding of examples. However, one skilled in the relevant art will understand that the aspects described can be practiced without these specific details.

[0032] First, referring to Figure 1 , the overall structure of the pool cleaning robot 100 of the present application is described. As shown in Figure 1 , the pool cleaning robot of the present application includes a housing 110, a flow channel structure 120, a filter structure 130, a drainage device 140, a driving mechanism 150, a walking mechanism 160 and a cleaning brush 170.

[0033] The housing 110 is the main structure of the pool cleaning robot, and the flow channel structure 120 is provided inside the housing 110, which is a water flow channel for water flow, and the filter structure 130 is provided in the flow channel structure 120 to filter the water flowing through the flow channel structure 120, wherein the drainage device 140 is also provided in the flow channel structure 120 and provides power to drain 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 which can rotate to clean the pool bottom or pool wall, and the driving mechanism 150 is responsible for driving the walking mechanism 160 and the cleaning brush 170 to clean the pool during walking.

[0034] In the present application, the housing 110 can be made of plastic and internally provided with a cavity to accommodate the filter structure 130 such as a filter screen, impurities cleaned by the cleaning brush 170 enter the flow channel structure 120 through, for example, the water inlet at the bottom of the pool cleaning robot, and then filtered through the filter screen, so that the filtered water is discharged from the top of the pool cleaning robot 100 by the drainage device 140 such as a screw mechanism, while impurities and the like are retained in the filter screen to achieve the cleaning operation of the pool.

[0035] Next, referring to Figure 2 , a detachable battery structure of a pool cleaning robot of the present application is described, which includes an outer housing 1 and an inner housing 2 to form a housing interlayer 3 between the outer housing 1 and the inner housing 2, and the detachable battery structure of the present application is arranged in the housing interlayer 3 formed between the outer housing 1 and the inner housing 2.

[0036] Specifically, referring to Figure 3And Figure 4 The detachable battery structure includes a battery cavity 4 arranged in the shell interlayer 3, and the bottom of the battery cavity 4 is provided with positive and negative electrodes for facilitating the electrical connection of the battery 6. The battery cover plate 5 serves to fix and protect the battery 6, and the battery 6 is fixed on the battery cover plate 5 and forms an integrated structure with the battery cover plate 5. The battery cover plate 5 is firmly combined with the outer shell 1 (refer to Figure 3 ) by mechanical connection or fixed connection, so as to ensure the structural stability and waterproof performance.

[0037] It is particularly noted that the battery cover plate 5 and the battery 6 are formed as a whole in the present application, and it is also useful to fix the battery cover plate 5 to the outer shell 1, because the robot 1 works underwater for a long time. If the battery 6 is fixed in the battery cavity 4 and then sealed by the battery cover plate 5, the fastening of the battery 6 and the fastening of the battery cover plate 5 will be two parts of fastening, and any one part of sealing that is not tight enough can cause the battery 6 to be flooded. By integrally forming the battery cover plate 5 with the battery 6 and fixing the battery cover plate 5 to the outer shell 1, it is only necessary to ensure the sealing of the battery cover plate 5 to the battery cavity 4.

[0038] In addition, the battery cover plate 5 is provided with a groove 7, and a waterproof sealing ring 8 is arranged in the groove 7. The waterproof sealing ring 8 is tightly matched with a protrusion 9 on the outer edge of the battery cavity 4, so as to achieve a high-efficiency waterproof effect. In order to further improve the waterproof performance, the surface of the waterproof sealing ring 8 is coated with a layer of sealing grease 10, so as to increase the waterproof sealing effect.

[0039] The above design effectively solves the problem of waterproofing of the battery 6 of the pool cleaning robot. The conventional battery 6 installation method often cannot achieve long-term and stable waterproofing effect, especially in a humid environment such as a pool, the battery 6 is prone to failure and even safety hazards due to water intrusion. The detachable battery structure of the present application is designed with multiple levels of waterproofing, especially the combination of the groove 7 and the sealing ring on the battery cover plate 5, and the additional sealing grease 10, which not only ensures the waterproof performance of the battery 6, but also improves the convenience of disassembly and assembly, facilitates the user to regularly maintain and replace the battery 6, and thus ensures the reliability and long-term use of the pool cleaning robot.

[0040] In one embodiment, at least one annular protrusion 11 (see Figure 3 ) is arranged around the positive and negative electrodes of the detachable battery structure of the pool cleaning robot of the present application. The annular protrusion 11 serves to enhance the sealing between the electrodes and the connecting parts of the battery 6, so as to effectively prevent water from penetrating into the inside of the battery 6. The specific arrangement form of the annular protrusion 11 can form one or more continuous or discontinuous protrusions around the periphery of the electrodes, and the height and width of the protrusions can be adjusted according to actual needs to ensure that they can effectively play a sealing role during assembly.

[0041] Specifically, the position of the annular protrusion 11 is arranged around the electrode at the bottom of the battery cavity 4. Such a design not only provides physical blocking, but also enhances the reliability of electrical connection. In this way, the annular protrusion 11 can closely fit the inner wall of the battery 6 connector when the battery 6 is inserted and removed, further improving the sealing performance and connection stability of the entire system.

[0042] For example, in a specific embodiment, an injection molding process can be used to integrally form the annular protrusion 11 on the insulating material around the electrode. This design not only simplifies the manufacturing process, but also improves production efficiency and product quality.

[0043] In one embodiment, the cross-sectional shape of at least one annular protrusion 11 of a detachable battery structure of a pool cleaning robot of the present application is conical or arc-shaped. This design helps to ensure that the positive and negative electrodes are connected with the sealing of the battery positive and negative poles. These annular protrusions 11 can be molded by a mold during the manufacturing process, ensuring dimensional consistency and shape accuracy. The number of annular protrusions 11 can be adjusted according to actual needs to provide sufficient mechanical strength and sealing.

[0044] The cross-sectional shape of the annular protrusion 11 can be selected to be conical or arc-shaped. When selecting a conical shape, the height of the annular protrusion 11 gradually decreases from the root to the top, forming a certain inclination angle, which helps to deform the annular protrusion 11 when installing the battery 6, thereby increasing the sealing. When selecting an arc shape, the cross-section of the annular protrusion 11 is a smooth arc, which can provide good sealing effect while maintaining contact area.

[0045] In one embodiment, as shown in Figure 4 A soft waterproof gasket 12 is installed around the positive and negative poles of the battery 6 of a detachable battery structure of a pool cleaning robot of the present application. The soft waterproof gasket 12 not only plays a waterproof role, but also has certain buffering and shockproof functions, thereby protecting the positive and negative poles of the battery 6 from being damaged during use. The height of the soft waterproof gasket 12 is designed to be lower or level with the horizontal plane, ensuring that it can be in contact with at least one annular protrusion 11 when installed in place, thereby achieving effective sealing. In addition, the annular protrusion 11 is usually installed on the inner wall of the battery 6 slot, which further enhances the waterproof performance. Specifically, the soft waterproof gasket 12 is fixed around the positive and negative poles of the battery 6 by means of adhesive, ensuring that it will not fall off during the installation and removal of the battery 6.

[0046] For example, to achieve the above features, a soft material ring-shaped gasket can be provided around the positive and negative poles of the battery 6. The soft material can be silicone or rubber. During installation, the battery 6 is placed in the battery cavity 4, and the soft waterproof gasket 12 is in close contact with the annular protrusion 11 at the bottom of the battery cavity 4. In this way, even when working underwater, the combination of the soft waterproof gasket 12 and the annular protrusion 11 can effectively prevent water from entering the interior of the battery 6, ensuring the safety and reliability of the battery 6.

[0047] Referring back Figure 3 In one embodiment, the top of the battery cavity 4 of the pool cleaning robot of the present application is provided with a clearance slot 13. The lower edge of the inner wall of the clearance slot 13 is lower than the bottom of the battery cover plate 5. This design makes it more convenient and easy for the user to take out the battery 6, effectively avoiding the inconvenience caused by the limited space.

[0048] The clearance slot 13 is located at the top of the battery cavity 4 and extends to one side of the battery cavity 4 to form an opening. This structural design allows the battery 6 to be easily taken out or put in through the opening after the user opens the battery cover plate 5. Specifically, when the user needs to replace the battery 6, he or she can simply insert his or her fingers into the clearance slot 13 to grasp the battery 6 and complete the replacement operation. In addition, the lower edge of the inner wall of the clearance slot 13 is designed to be lower than the bottom of the battery cover plate 5, which not only provides a clear operating area for the user, but also prevents the user's hand from interfering with the battery cover plate 5 during the taking process.

[0049] Specifically, the size of the clearance slot 13 should be optimized according to the actual size of the battery 6. Specifically, the width and depth of the clearance slot 13 should be slightly larger than the size of the battery 6 to ensure that the user will not feel difficult during the operation due to insufficient space. In addition, the inner wall of the clearance slot 13 can be designed with a smooth transition to reduce friction on the user's fingers and improve the comfort of the operation. For example, the battery cavity 4 can be manufactured by one-time molding to ensure the accurate position and shape of the clearance slot 13 and the inner wall.

[0050] In one embodiment, the battery cover plate 5 of the detachable battery structure of the pool cleaning robot of the present application is connected to the outer shell 1 by screws 14, and the position of the screws 14 is set on the outside of the battery cavity 4 to prevent interference with the installation of the waterproof sealing ring 8. This design ensures that the internal components of the battery 6 structure can be effectively protected from water erosion during disassembly and installation. Specifically, the battery cover plate 5 and the outer shell 1 are fixed by a plurality of screws 14, which are distributed at predetermined positions outside the battery cavity 4. By arranging the screws 14 on the outside, direct contact between the screws 14 and the waterproof sealing ring 8 is avoided, thereby ensuring the sealing effect.

[0051] For example, in practical applications, the outer shell 1 is provided with hole positions dedicated to fixing the screws 14, which are evenly distributed on the outer periphery of the battery cavity 4, ensuring that the cover plate can be firmly combined with the outer shell 1 without damaging the position and integrity of the waterproof sealing ring 8. Specifically, the size and shape of the battery cover plate 5 are designed to match the battery cavity 4, ensuring that the screws 14 do not have any adverse effects on the internal battery 6 and other electronic components after being fixed.

[0052] In one embodiment, still referring to Figure 3 , the distance between the screws 14 on one side of the battery cover plate 5 of a detachable battery structure of a pool cleaning robot of the present application is different from the distance between the screws 14 on the other side, thereby facilitating the user to determine the correct direction during installation. With this asymmetric design, the correct direction of the battery cover plate 5 can be easily determined even in poor lighting conditions. Specifically, the distance between the two screws 14 on one side of the battery cover plate 5 is greater than the distance between the two screws 14 on the other side. Such a design simplifies the installation steps and reduces installation failures due to incorrect orientation.

[0053] Specifically, two screws 14 can be fixed on one side of the battery cover plate 5, and the distance between the two screws 14 is X millimeters; while on the other side, two screws 14 are also fixed, but the distance between the two screws 14 is Y millimeters, and Y is greater than X. In this way, the user only needs to compare the distance between the screws 14 on both sides to determine the correct installation direction. For example, in actual design, X can be selected as 20 millimeters and Y as 30 millimeters, so that the significantly different distance difference can ensure that the direction determination during installation is more intuitive and reliable.

[0054] In one embodiment, a vertical limiting rib 15 is installed on the inner wall of the battery cavity 4 of a detachable battery structure of a pool cleaning robot of the present application. The main function of the limiting rib 15 is to provide accurate positioning when the battery 6 is inserted into the battery cavity 4 and to prevent the battery 6 from shifting due to vibration or impact during operation. The limiting rib 15 is arranged along the longitudinal direction of the battery cavity 4 by being fixed on the inner wall of the battery cavity 4, ensuring that the battery 6 enters and exits the cavity smoothly along the predetermined trajectory. This design not only improves the assembly accuracy of the battery 6, but also enhances the stability of the overall structure.

[0055] For example, the limiting rib 15 can be made of high-strength plastic or metal material and formed integrally on the inner wall of the battery cavity 4. Specifically, the limiting rib 15 can be a continuous or spaced multiple protrusions to ensure reliable support and guidance for different parts of the battery 6. This design makes it more convenient and safe for the user to replace the battery 6, reducing the possibility of misoperation.

[0056] In one embodiment, the detachable battery structure of the pool cleaning robot of the present application is characterized in that the battery cavity 4 is integrally formed with the positive and negative electrodes. This design makes the battery 6 assembly more convenient during assembly and replacement, while ensuring the stability and reliability of the battery 6 connection. Specifically, the battery cavity 4, as the main component for installing the battery 6, not only provides physical support, but also undertakes the important function of electrical energy transmission. By integrating the positive and negative electrodes with the battery cavity 4, the internal structure is simplified, the assembly steps and the number of parts are reduced, and the compactness and consistency of the overall design are improved.

[0057] In terms of technical implementation, the integration of the battery cavity 4 with the positive and negative electrodes can be achieved through various materials and processes. For example, an injection molding process can be used to form the battery cavity 4 and the positive and negative electrodes into a whole component in the same step. Specifically, a composite material with good electrical conductivity can be selected to ensure that the positive and negative electrode parts have good electrical connectivity, while the battery cavity 4 part provides sufficient mechanical strength and sealing to ensure the stability and durability of the entire assembly during installation and use.

[0058] Above, the detachable battery structure of the present application has been described with reference to the accompanying drawings. Next, another embodiment of the detachable battery structure of the present application is described with reference to Figure 5 , the drawings.

[0059] As shown in Figure 5 , unlike the structure of the battery 6 shown in Figure 4 , in addition to the battery positive and negative electrodes, a communication interface is also provided within the range of the soft waterproof gasket 12, which can be a communication PIN, for example. Correspondingly, as shown in Figure 6 , a communication PIN can be provided at the corresponding position inside the battery cavity 4, more specifically within the annular protrusion 11, and the two are electrically connected. In other words, in the present application, a first communication PIN 16 can be provided at the bottom of the battery 6, and a second communication PIN 17 can be provided at the bottom of the battery cavity 4, and the two are electrically connected. In this way, the second communication PIN 17 provided at the bottom of the battery cavity 4 can send a signal to the battery 6 via the second communication PIN 17 and the first communication PIN 16 on the battery 6 to disconnect the power output of the battery 6 after detecting water in the motor compartment where the motor is installed, thereby improving the overall safety.

[0060] More specifically, the battery first communication PIN 16 establishes an electrical connection with the battery cavity 4 second communication PIN 17, and the second communication PIN 17 is in communication with the internal master control system MCU communication interface through the battery compartment body wall, so that the battery and the master control system MCU establish communication through IIC, UART, RS485 or other communication protocols. Specifically, the battery can send a query instruction to query the working state of the master control system MCU at a fixed time interval, and the MCU sends a response instruction to the battery within a limited time after receiving the query instruction; or the MCU automatically sends a heartbeat instruction to the battery at a fixed time interval, and the battery passively receives the heartbeat instruction. The battery determines the working state of the MCU by whether it receives the MCU response instruction or heartbeat instruction on time. If water ingress causes the master control circuit MCU to malfunction, it cannot normally send instructions to the battery within a limited time, and the battery will determine that the master control system MCU is not normally started due to water leakage short circuit, and automatically cut off the power supply to the motor compartment, thereby improving the overall safety.

[0061] In actual operation, when the device is in use, first, the battery 6 is installed on the battery cover plate 5 and ensured to be firmly fixed. Then, the battery cover plate 5 with the battery 6 is fixed on the outer shell 1, so that the groove 7 on the battery cover plate 5 matches the protrusion 9 on the outer edge of the battery cavity 4. The waterproof sealing ring 8 is placed inside the groove 7, and the surface is pre-coated with sealing grease 10 to enhance the waterproof performance. With the installation of the battery cover plate 5, the waterproof sealing ring 8 tightly fits on the protrusion 9 on the outer edge of the battery cavity 4, forming a reliable seal to prevent water from entering the inside of the battery cavity 4. At the same time, the positive and negative electrodes at the bottom of the battery 6 respectively contact the corresponding design points inside the battery 6, establishing an electrical connection. In this way, the power of the battery 6 can be smoothly transmitted to each part of the entire pool cleaning robot, including the drive mechanism, the walking mechanism, the cleaning brush, the filtering structure, and the drainage device, and other key components.

[0062] The above describes the preferred embodiments of the present application. It should be noted that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the scope of the present application.
