Description

Technical Field

[0001] This utility model belongs to the field of robotics technology, specifically relating to the waterproof structure of the control box of a pool cleaning robot. Background Technology

[0002] Swimming pools are designated venues for people to engage in swimming activities or competitions. As such, swimming pools inevitably accumulate various impurities during their daily operation and use, such as debris, algae, and microorganisms. Given that the hygiene of the pool water environment directly affects the health and experience of users, regular and standardized cleaning is a crucial aspect of pool operation and management. Traditional pool cleaning relies primarily on internal circulation and filtration systems, along with manual processes such as bottom cleaning, wall wiping, and vacuuming, resulting in unsatisfactory cleaning outcomes and requiring significant time and labor costs.

[0003] With the rapid development of automation technology, pool cleaning machines have appeared on the market, capable of submerging in water to clean dirt from pool walls, saving manual labor. However, a problem arises: how to ensure the proper functioning of the various electrical systems within these machines. Since the robots operate in a submerged environment for extended periods, preventing water seepage and damage to the electrical systems is a pressing technical issue. Existing technology uses screws and various rubber sealing rings to seal installation gaps, but this method leads to cumbersome assembly, extends production time, and has poor waterproofing performance. Another method involves injecting waterproof adhesive into the installation space after assembling the electrical system, sealing it completely. However, this method consumes a significant amount of waterproof adhesive.

[0004] Therefore, this utility model provides a waterproof structure for the control box of a pool cleaning robot to solve the above problems. Utility Model Content

[0005] Therefore, the present invention aims to solve the technical problem of how to prevent water from seeping into the circuit system of the pool cleaning robot during use.

[0006] To solve the above-mentioned technical problems, this utility model provides a waterproof structure for the control box of a pool cleaning robot, including a box body, the box body including a box cover and a box, and the box cover and the box body forming an installation cavity for housing the control unit after installation.

[0007] An extension is integrally formed on the outer side of the box lid, and an embedded groove is provided at the connection between the extension and the box lid;

[0008] The outer side of the box is integrally provided with an outward expansion portion, and the end of the outward expansion portion is a first connecting portion. The first connecting portion is ultrasonically sealed to the inner groove. The extension portion and the box form a sealed cavity surrounding the outer side of the box. The sealed cavity is filled with a sealing structure that seals between the first connecting portion and the inner groove.

[0009] Furthermore, both the extension and the expansion portion have an L-shaped longitudinal section, and the engagement position between the inner groove and the first connecting portion is a concave-convex connection that is compatible. Through this design, the extension and the expansion portion extend vertically and engage with each other, with a certain engagement depth.

[0010] Furthermore, two layers of ultrasonic sealing contact are provided between the first connecting part and the inner groove.

[0011] Furthermore, a first ultrasonic sealing contact is provided at the junction of the bottom of the embedded groove and the end of the first connecting part, and a second ultrasonic sealing contact is provided at the junction of the end of the inner wall of the embedded groove and the first connecting part.

[0012] Furthermore, the contact surface between the end of the first connecting part and the inner groove is a plane or a concave surface.

[0013] Furthermore, the end of the extension is parallel to the bottom of the box, or extends beyond the bottom of the box and is located below the box;

[0014] The depth of the sealed cavity shall be at least 30% of the total height of the box.

[0015] Furthermore, the sealing structure is made of waterproof adhesive material and covers the outside of the box. With this design, the sealing structure can be placed only in the sealing cavity, or it can extend beyond the bottom of the box and cover the bottom of the box, resulting in a better sealing effect.

[0016] Furthermore, the inner end of the bottom of the lid engages with the inner end of the outward expansion to form a stop area, which serves as a positioning function.

[0017] Furthermore, the first connecting portion is conical in shape, with the end closest to the inner groove having the largest diameter.

[0018] Furthermore, a rubber button is provided on the top of the box lid, and glue-soaked ends are provided at both the top and bottom of the connection between the box lid and the rubber button.

[0019] Furthermore, a cable management conduit is installed at the bottom of the box.

[0020] The technical solution provided by this utility model has the following advantages: the sealing structure is filled into the sealing cavity by injection, and the sealing structure is formed after the adhesive material cools and solidifies. The waterproof adhesive material has strong fluidity in the gel state, which can completely seal the gap between the first connection part and the inner groove. When the robot is used underwater, external water cannot enter the sealing cavity, ensuring the good operation of the control unit in the installation cavity and avoiding the control unit from malfunctioning when it comes into contact with water. Using this method to seal the cover and the box body eliminates many locking steps and bolt parts, and can effectively improve waterproof performance, especially suitable for immersion-type swimming pool cleaning environment;

[0021] The control unit in the mounting cavity has no obstruction structure, and the rubber button can trigger the buttons on the control unit without reducing the sensitivity of the buttons. Attached Figure Description

[0033] This embodiment provides a waterproof structure for the control box of a pool cleaning robot, applicable to pool environment cleaning. Please refer to... Figure 1 and Figure 2 The control box of the pool cleaning robot has a waterproof structure including a box body 1, which consists of a cover 2 and a box 3. The cover 2 and the box 3 are installed together to form an installation cavity 301. The box 3 is equipped with various trays and plate structures for installing the robot control unit. The robot control unit can be installed in the box by screws or snap-fit.

[0034] Please see Figures 1-5 Sealing installation of lid 2 and box 3: The bottom end of lid 2 is provided with an integrally formed extension 201, and the connection between extension 201 and lid 2 is provided with an embedded groove 202 (e.g., Figure 4 The outer wall of the box 3 is provided with an integrally formed outward expansion 302. The top end of the outward expansion 302 is a first connecting part 303. The first connecting part 303 is engaged upward in the inner groove 202. The longitudinal section of the extension 201 and the outward expansion 302 are both L-shaped. The extension 201 extends downward and the outward expansion 302 extends upward. The two extend upward and engage with each other. The engagement position between the inner groove 202 and the first connecting part 303 is matched with the concave and convex joints to increase the connection area and improve the connectivity.

[0035] Furthermore, such as Figure 3 and Figure 4The end of the first connecting part 303 abuts against the inner groove 202, and the abutment point between the first connecting part and the inner groove is ultrasonically sealed. This design is to ensure a seal at the contact surface between the first connecting part 303 and the inner groove 202, and also to reduce the seepage of the sealing structure 5 into the mounting cavity 301 during subsequent adhesive injection. Figure 5 The contact surface between the end of the first connecting part 303 and the inner groove 202 can also be a concave-convex mating surface, one of which is a concave surface and the other is a convex surface, and the concave-convex mating surface is ultrasonically sealed.

[0036] Furthermore, two layers of ultrasonic sealing contact are provided between the first connecting part 303 and the inner groove 202 (e.g., Figure 6 This enhances the reliability of the seal. Specifically, a first ultrasonic sealing contact is provided at the bottom of the embedded groove where it abuts against the end of the first connecting part, and a second ultrasonic sealing contact is provided at the end of the inner wall of the embedded groove where it abuts against the first connecting part, forming a double sealing structure. The internal recess of this sealing method forms a meandering shape, resulting in higher connection strength, improved waterproofing effect, and reduced risk of glue leakage.

[0037] Preferred, such as Figure 3 and Figure 4 The inner end of the bottom of the lid 2 is inserted into the inner end of the outward expansion 302, and the insertion depth is greater than or equal to half of the total longitudinal length of the first connecting part 303, forming the second connecting part. The extension 201 and the bottom of the lid 2 form an embedded groove 202. When the first connecting part 303 is inserted into it, it plays a positioning role, and the second connecting part can block the inner side of the first connecting part 303, further preventing glue seepage.

[0038] Please see Figures 1-5 After the lid 2 and box 3 are installed, a sealing cavity 4 is formed between the extension 201 and the outer side of the box 3. The sealing cavity 4 surrounds the outer circumference of the box 3. The sealing structure 5 is made of a waterproof adhesive material, such as silicone rubber, polyurethane adhesive, epoxy resin adhesive, acrylic adhesive, or weather-resistant silicone adhesive. One of these materials can be selected. The sealing structure 5 is filled into the sealing cavity 4 by injection. After the adhesive material cools and solidifies, the sealing structure 5 is formed. After the sealing cavity 4 is filled with the sealing structure 5, it can seal the connection between the first connecting part 303 and the inner groove 202. Waterproof adhesive materials have strong fluidity in gel form, which can completely seal the gap between the first connecting part 303 and the inner groove 202. After solidification, they fill the sealing cavity 4. The sealing structure 5 is waterproof. When the robot is used underwater, external water cannot enter the sealing cavity 4, ensuring the proper operation of the control unit in the installation cavity 301 and preventing the control unit from malfunctioning when exposed to water. Using this method to seal the cover 2 and the body 1 eliminates many locking steps and bolt parts, and can effectively improve waterproof performance, especially suitable for immersion-type pool cleaning environments.

[0039] Furthermore, a sealing cavity 4 is formed between the extension 201 and the outer side of the box 3, and the filling depth of the sealing structure 5 depends on the longitudinal length of the extension 201 (e.g., Figure 3 The end of the extension 201 is parallel to the bottom of the box 3. The sealing structure 5 fills the sealing cavity 4 and covers the outer wall of the box 3. Of course, if higher waterproofing is required, the end of the extension 201 can also be designed to extend beyond the bottom of the box 3 and be located below the box 3 (e.g., Figure 5 The sealing structure 5 fills the sealing cavity 4 and seeps out of the sealing cavity 4 by ≥0.8mm. The sealing structure 5 will cover the outside and bottom of the box 3, covering all the parts of the box 3 exposed to the outside world, resulting in a better sealing effect. Moreover, the sealing structure 5 is not easy to detach from the box body 1.

[0040] Furthermore, such as Figure 4 As shown, the first connecting part 303 is conical in shape, with the largest diameter at the end closest to the inner groove 202. The diameter gradually narrows from top to bottom. The outer wall of the first connecting part 303 is inclined, and there is a glue seam between it and the extension part 201. The glue seam is triangular in shape. Thus, when the sealing structure 5 is injected with glue, it enters the glue seam. After molding, the sealing structure 5 can fix the connection between the first connecting part 303 and the inner groove 202. The triangular sealing structure 5 in the glue seam can form stress to position the first connecting part 303, ensuring the connection strength.

[0041] Please see Figure 1 and Figure 7 The top of the lid 2 is provided with a rubber button 7. Both the upper and lower ends of the connection between the lid 2 and the rubber button 7 are provided with glue-inserting ends. The upper and lower ends of the glue-inserting ends are concave. The rubber button 7 is preferably molded on the top of the lid 2. Before the lid 2 is connected to the box 3, the rubber button 7 is placed in the mold for injection molding. The glue-inserting ends can hold the rubber button 7 in place, preventing the rubber button 7 from detaching from the lid 2. This installation method can also ensure the seal at the connection between the rubber button 7 and the lid 2, achieving a waterproof effect.

[0042] Please see Figure 1 Below the box 3, there is a cable tray 6. The cable tray 6 is connected to the inside of the mounting cavity 301. After the control unit is installed into the mounting cavity 301, the connection line can be routed through the cable tray 6 to output to the various drive components in the robot and make electrical connections with them. In order to better waterproof and seal, after the cable is routed, adhesive material can be injected into the remaining space in the cable tray 6 to seal the cable tray 6, ensuring waterproof sealing, and at the same time fixing the connection line to prevent it from moving in the cable tray 6.

[0043] For specific implementation scenarios, please refer to Figure 7The waterproof control box structure provided in the above embodiment is installed on the upper shell of the pool cleaning robot, with a portion exposed for user operation. The outer surface of the control box housing 1 is covered with a soft rubber structure, and buttons corresponding to the soft rubber structure are located inside. Users can control the pool cleaning robot by pressing the soft rubber.

[0044] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
