[0001] This application relates to the field of underwater cleaning machine technology, and more particularly to a sealed box structure and an underwater cleaning machine. Background Technology
[0002] An underwater cleaning machine is a device used to clean the bottom and walls of pools, bathtubs, fish ponds, and other similar water features. Underwater cleaning machines are motor-driven and equipped with various sensors. To integrate the different control functions of the underwater cleaning machine and achieve comprehensive control and management, the electronic equipment controlling the motor and communicating with the sensors is typically integrated into a sealed enclosure.
[0003] However, in actual operation, the detection data of the detection elements may deviate due to the influence of the underwater cleaning machine. Utility Model Content
[0004] This application provides a sealed box structure and an underwater cleaning machine, which can solve the problem in related technologies where the detection data of the detection element is deviated due to the influence of the underwater cleaning machine.
[0005] In a first aspect, embodiments of this application provide a sealed box structure for an underwater cleaning machine, comprising: A sealing box assembly is disposed inside the underwater cleaning machine. The sealing box assembly forms an inner cavity and a through hole communicating with the inner cavity. A detection element is disposed within the inner cavity, the detection element having a detection part located at the through hole; and... A through-tube is connected to the sealing box assembly, with one end of the through-hole communicating with the through-hole and the other end extending to the outside of the underwater cleaning machine.
[0006] In some embodiments, the sealing box assembly is provided with a sleeve that communicates with the through hole, and the through tube is sleeved on the sleeve.
[0007] In some embodiments, the sealing box assembly includes a sealing box forming the inner cavity and a through hole communicating with the inner cavity, and the sealing box protruding outward to form the sleeve.
[0008] In some embodiments, the sealing box assembly includes: A sealed box, forming the inner cavity and a through hole communicating with the inner cavity; and, An outer frame is connected to the sealing box, the outer frame forms a channel communicating with the through hole, and the outer frame protrudes outward at the channel to form the sleeve.
[0009] In some embodiments, the sealing box structure further includes a sealing gasket disposed between the sealing box and the outer frame to seal the gap between the channel and the through hole.
[0010] In some embodiments, the conduit is a flexible hose and is elastically pressed against the outer wall of the sleeve.
[0011] In some embodiments, the sealing box structure is provided with a hook, and the through pipe is snapped into the hook.
[0012] In some embodiments, the detection element includes at least one of a depth sensor, a pH sensor, and a TDS sensor.
[0013] Secondly, embodiments of this application provide an underwater cleaning machine, comprising: The housing has mounting holes; and, As described above, the sealing box structure is installed inside the housing, and the end of the through pipe away from the through hole extends out of the housing through the mounting hole.
[0014] In some embodiments, the housing includes: The main body, the sealing box structure is installed inside the main body, the mounting hole is provided on the main body, and, A side shell is provided on the outside of the main body and forms an anti-clogging cavity and an opening communicating with the anti-clogging cavity between the side shell and the main body.

[0015] Based on the sealing box structure and underwater cleaning machine of this application embodiment, the sealing box structure includes a sealing box assembly and a through pipe.

[0018] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.
[0019] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0020] In related technologies, during actual operation, the detection data of depth sensors may be deviated due to the influence of underwater cleaning machines.
[0021] It is understandable that the water circulation and impeller rotation during robot cleaning will create local turbulence inside the casing, and the frequent changes in water speed and direction will affect the accuracy of detection by the detection elements.
[0022] To resolve the above issues, please refer to [link / reference]. Figures 1 to 2 This application provides an underwater cleaning machine 1, which includes a housing 200 and a sealed box structure 100.
[0023] Among them, the underwater cleaning machine 1 uses built-in cleaning brushes, suction devices and other components to clean the dirt on the bottom and side walls of the pool, achieving full-coverage cleaning.
[0024] The housing 200 serves as the exterior component of the entire underwater cleaning machine 1, protecting the internal structure. The housing 200 also provides an assembly reference for other components such as cleaning brushes and drive wheels.
[0025] The sealed box structure 100 centrally accommodates multiple sensors, reducing the installation space occupied by individual components and adapting to the compact layout requirements of the underwater cleaning machine 1. The sealed box structure 100 can also form an independent sealed inner cavity 10a, reducing the possibility of impurities such as pool water, mud, and cleaning agents seeping in, and avoiding short circuits, corrosion, or contact contamination of the sensors.
[0026] In one embodiment of this application, please refer to Figures 4 to 6 The sealing box structure 100 includes a sealing box assembly 10 and a through pipe 20. The sealing box assembly 10 forms an inner cavity 10a and a through hole 10b communicating with the inner cavity 10a. A detection element 30 is provided in the inner cavity 10a. The detection element 30 has a detection part located at the through hole 10b. The through pipe 20 is connected to the sealing box assembly 10. One end of the through pipe 20 communicates with the inner cavity 10a, and the other end extends to the outside of the underwater cleaning machine 1.
[0027] The sealing box assembly 10 is located inside the underwater cleaning machine 1, that is, inside the housing 200. It can be installed inside the housing 200 by means of snap-fit and / or fastener connection, so that the housing 200 provides a certain degree of protection for the sealing box assembly 10.
[0028] The inner cavity 10a of the sealing box assembly 10 serves as the main housing space for the detection element 30. It can be sealed by sealing rings and sealant to isolate moisture and impurities (such as mud and sand generated during cleaning) inside the housing 200, and prevent the detection element 30 from short-circuiting, corroding or contacting contamination. On the other hand, the sealing box assembly 10 can also buffer the vibration caused by water flow impact, reduce the impact of vibration on sensitive elements, and reduce the risk of signal drift.
[0029] The connecting pipe 20 establishes a communication path between the detection element 30 and the water in the pool, preventing the detection element 30 from being directly exposed to the turbulence and eddies inside the casing 200. The flow velocity and direction of the water in the connecting pipe 20 are more stable, allowing the detection element 30 to be in near-ideal detection conditions. Since the detection element 30 is mainly used to detect the condition of the water in the pool, the connecting pipe 20 can directly detect the condition of the water in the pool outside the casing 200, ensuring that the detection element 30 detects the true parameters of the water in the pool.
[0030] The detection element 30 may include at least one of a depth sensor, a pH (potential of hydrogen) sensor, and a TDS (Total Dissolved Solids) sensor.
[0031] The depth sensor calculates the water depth by detecting water pressure, providing real-time feedback on the cleaning machine's underwater depth to ensure it operates within a preset depth range. The pH sensor measures the pH value of the pool water to determine if the water's acidity or alkalinity meets standards, ensuring the water quality is within a safe range. This prevents excessive acidity from corroding cleaning machine components and excessive alkalinity from causing scale buildup, while also protecting the user's skin. The TDS sensor detects the total dissolved solids (TDS) content in the water, including soluble salts, minerals, and organic matter, to determine the water's purity and level of contamination.
[0032] Thus, through the setting of the through pipe 20, the detection element 30 can directly detect the working condition of the water in the pool outside the housing 200. When the detection element 30 is a depth sensor, the dynamic pressure impact caused by turbulence inside the housing 200 can be avoided. The water flow velocity inside the through pipe 20 is low and the pressure is stable. The sensor captures the static pressure signal of the pool water, which reduces the pressure superposition deviation caused by water flow fluctuations and ensures that the depth sensor detects the real parameters of the pool water.
[0033] When the detection element 30 is a pH sensor, the tube 20 collects the uniform water body outside, rather than the local water body that is stirred up inside the casing 200. This avoids instantaneous differences in hydrogen ion concentration in local areas, such as the mixing of sewage during cleaning or the local accumulation of chemical residues, making the pH value detection closer to the true average state of the water body.
[0034] When the detection element 30 is a TDS sensor, the through pipe 20 guides the external stable water body to flow through the detection section, avoiding the uneven concentration of local dissolved substances caused by the water flow stirring inside the casing 200. The sensor collects the overall conductivity signal of the water body, and the converted TDS data is more accurate.
[0035] It is understandable that, since the depth sensor calculates the water depth of the pool by detecting water pressure, the detection method is relatively direct. Therefore, in this embodiment, the detection element 30 is used as the depth sensor for illustrative purposes. Correspondingly, the detection part is the pressure sensing surface of the depth sensor.
[0036] The sealing box assembly 10 needs to be sealed, so an elastic sealing structure can be provided at the gap between the detection part and the through hole 10b to achieve the sealing between the through hole 10b and the inner cavity 10a.
[0037] Furthermore, in one embodiment of this application, please refer to Figures 2 to 3The housing 200 has a mounting hole 200a. The end of the tube 20 away from the through hole 10b extends to the outside of the housing 200 through the mounting hole 200a. That is, the tube 20 passes through the mounting hole 200a. The mounting hole 200a can provide a fixed channel for the tube 20 of the sealing box, so that the tube 20 can be precisely extended to the outside of the housing 200 without damaging the overall performance of the housing 200.
[0038] In one embodiment, the housing 200 includes a main body 210 and a side shell 211. The sealing box structure 100 is installed inside the main body 210, and the mounting hole 200a is provided on the main body 210. The main body 210 serves as the main skeleton of the cleaning machine, fixing the sealing box structure 100, motor, gears and other core internal components, providing precise installation positioning, and ensuring that the layout of each component is reasonable and the connection is firm.
[0039] The side shell 211 can be integrally formed with the body 210 or connected by fasteners. The side shell 211 can be used as a decorative part or its shape can be optimized to achieve a flow guiding function and reduce the walking resistance of the underwater cleaning machine 1.
[0040] In the application embodiment, the side shell 211 is disposed on the outside of the body 210, and forms an anti-blocking cavity 211a and an opening 211b communicating with the anti-blocking cavity 211a between the side shell 211 and the body 210. The mounting hole 200a communicates with the anti-blocking cavity 211a, and one end of the through pipe 20 away from the through hole 10b extends through the mounting hole 200a to the anti-blocking cavity 211a.
[0041] As the outer wall of the anti-clogging cavity 211a, it together with the main body 210 encloses an independent buffer space. Water from the pool is guided into the anti-clogging cavity 211a through the preset opening 211b, while preventing large particles of debris from directly contacting the port of the pipe 20, thus realizing the core function of anti-clogging.
[0042] In addition, the side shell 211 shields the mounting hole 200a on the main body 210 and the extension end of the through pipe 20, preventing sharp objects and collisions from directly damaging the port of the through pipe 20 and extending the service life of the through pipe 20.
[0043] It is understandable that the through pipe 20 and the sealing box assembly 10 can be integrated or separate. When the through pipe 20 and the sealing box assembly 10 are integrated, there are no splicing gaps, preventing moisture and impurities from seeping into the inner cavity 10a from the connection surface of the through pipe 20 and the sealing box assembly 10. This is suitable for underwater high-pressure and long-term immersion environments, and the overall structural strength is better. It can be molded and processed in one piece, without the need for separate production and assembly of the through pipe 20 and the sealing box assembly 10, thus simplifying the production process.
[0044] When the connecting pipe 20 and the sealing box assembly 10 are separated, the connecting pipe 20 can be replaced separately without replacing the entire sealing box assembly 10, which greatly reduces maintenance costs. The connecting pipe 20 can be quickly disassembled for cleaning (such as silt blockage) or replaced with a connecting pipe 20 made of different materials to adapt to complex water quality scenarios.
[0045] In this embodiment, the through pipe 20 and the sealing box assembly 10 are described separately as an example.
[0046] Furthermore, in one embodiment of this application, a sleeve 11 is provided on the sealing box assembly 10, the sleeve 11 is connected to the through hole 10b, and the through pipe 20 is sleeved on the sleeve 11.
[0047] In this embodiment, the socket 11 is a tubular structure, and the through pipe 20 and the socket 11 are nested together, resulting in a larger contact area and ensuring excellent connection strength. This allows it to resist vibration and water flow impact during the operation of the underwater cleaning machine 1, preventing the through pipe 20 from shifting or falling off, and ensuring that the through pipe 20 always maintains a stable connection with the inner cavity 10a and the external water pool, without interrupting the transmission of the detection medium of the detection element 30.
[0048] The socket 11 provides a clear assembly positioning benchmark. The tube 20 can be directly inserted to complete the connection without complicated calibration, which improves the assembly efficiency of the whole machine. During maintenance, the tube 20 can be directly pulled out for replacement or cleaning. If the tube 20 is blocked or damaged, it is also convenient to replace the tube 20 of different specifications.
[0049] In this embodiment, the socket 11 provides a dedicated connection interface for the tube 20. A sealing ring, such as an O-ring or a stepped sealing structure, can be designed on the contact surface to increase the contact area between the tube 20 and the sealing box and further reduce the possibility of the tube 20 falling off.
[0050] Following the above, in the first embodiment of this application, the sealing box assembly 10 includes a sealing box 12, the sealing box 12 forming an inner cavity 10a and a through hole 10b communicating with the inner cavity 10a, and the sealing box 12 protruding outward to form a sleeve 11.
[0051] The socket 11 and the sealing box are integrated into one structure without any additional splicing gaps, which reduces the risk of moisture and impurities seeping into the inner cavity 10a from the connection surface. There is no need to assemble the connection structure between the sealing box 12 and the socket 11 separately, avoiding sealing failure caused by secondary assembly, and making it more suitable for underwater high-pressure environments.
[0052] On the other hand, the one-piece molding design allows the sealing box 12 and the socket 11 to be molded in one piece, simplifying the production process and making the connection between the socket 11 and the sealing box 12 stronger. This can withstand the vibration and water flow impact during robot operation and is less prone to deformation or breakage.
[0053] In addition, when assembling the sealed box structure 100, the through pipe 20 can be directly installed, which reduces assembly errors and production costs, and the overall space occupied is also smaller, making it suitable for the compact internal layout of the underwater cleaning machine 1.
[0054] In the second embodiment of this application, please refer to Figure 4 The sealing box assembly 10 includes a sealing box 12 and an outer frame 13. The sealing box 12 forms an inner cavity 10a and a through hole 10b communicating with the inner cavity 10a. The outer frame 13 is connected to the sealing box 12 and forms a channel 13a communicating with the inner cavity 10a. The outer frame 13 protrudes outward at the channel 13a to form a sleeve 11.
[0055] With the pipe 20 sleeved on the fitting 11, the channel 13a is connected to the pipe 20, meaning that the water in the pool outside the housing 200 can be transported to the detection element 30 through the pipe 20 and the channel 13a in sequence.
[0056] The outer frame 13 can be snapped onto the sealing box 12 or fixedly connected by screws or other threaded fasteners. Alternatively, it can be snapped onto the sealing box 12 first and then fixedly connected by screws or other threaded fasteners. When the socket 11 is damaged or other problems occur, the outer frame 13 can be removed from the sealing box 12 for repair or replacement, which improves maintenance efficiency and reduces maintenance costs.
[0057] The outer frame 13 is separate from the sealing box 12. The channel 13a size and socket 11 specification of the outer frame 13 can be designed separately, which can be compatible with pipes 20 of different inner diameters and materials, or adapt to the installation requirements of various detection elements 30.
[0058] The surface of the outer frame 13 can be provided with reinforcing ribs, so that the outer frame 13 can specifically undertake the functions of fixing and impact resistance, thereby providing better protection for the sealing box 12, which further ensures the stability of the internal detection element 30.
[0059] In the second embodiment described above, please refer to Figure 4 as well as Figure 5 The sealing box structure 100 also includes a sealing gasket 14, which is disposed between the sealing box 12 and the outer frame 13 to seal the gap between the channel 13a and the through hole 10b.
[0060] Specifically, the sealing gasket 14 can be located in the mounting cavity formed between the sealing box 12 and the outer frame 13. The mounting cavity can be formed by the inward recess of the outer frame 13. The mounting cavity is located at the end of the channel 13a and can be connected to the channel 13a or not connected to the channel 13a, that is, it is set to surround the channel 13a.
[0061] It can also be formed by the recess of the sealing box 12. The mounting cavity is located at the end of the through hole 10b and can be connected to the through hole 10b or not connected to the through hole 10b, that is, it is set to surround the through hole 10b.
[0062] It can also be formed by the outer frame 13 and the sealing box 12 being recessed together; there are no restrictions here, as long as the sealing is achieved.
[0063] In this embodiment, there is a small assembly gap between the outer frame 13 and the sealing box 12. The sealing gasket 14 is made of elastic rubber and is arranged in a ring shape. The sealing gasket 14 fills the gap with its own elasticity, reducing the possibility of water, mud and sand seeping into the through hole 10b from the gap. This makes it difficult for the data detected by the detection element 30 to be interfered with by the disturbed water inside the casing 200, thereby ensuring that the data of the detected water in the pool is more accurate.
[0064] The sealing gasket 14 has elastic deformation capability, which can compensate for the processing errors of the outer frame 13 and the sealing box 12 and the slight misalignment during assembly, so that the connecting surfaces fit more tightly and ensure the sealing effect.
[0065] When the passage tube 20 and the sealing box assembly 10 are described as separate components, in one embodiment of this application, the passage tube 20 is a flexible tube and is elastically pressed against the outer wall of the sleeve 11.
[0066] The hose can be made of rubber or silicone. With its own elasticity, the hose fits tightly against the outer wall of the fitting 11, automatically filling the tiny gap between them to form a flexible sealing surface. It can block water infiltration without the need for an additional sealing ring. The elastic and pressure-resistant fitting method can dynamically adjust with vibration and deformation, resulting in more stable sealing performance over long-term use.
[0067] During installation and disassembly, no fasteners are required; the flexible material can be directly fitted or removed. When cleaning blockages in the tube 20 or replacing the hose, there is no need to disassemble the sealing box or outer frame 13, resulting in high operational efficiency.
[0068] The flexible hose is soft and easy to bend, and can be slightly deformed. It can accommodate the small dimensional errors of the fitting 11 and the angular deviation during installation. There is no need to strictly calibrate the coaxiality, which reduces the precision requirements and costs of production and assembly. In addition, since the housing 200 is provided with mounting holes 200a to support the tube 20, the deformable function of the hose can also reduce the precision requirements of the mounting holes 200a.
[0069] It is also understandable that, within a certain length range, the weight of the hose is relatively light, and its impact on the buoyancy of the underwater cleaning machine 1 is minimal.
[0070] Please see Figure 5 and Figure 6In one embodiment of this application, a hook 15 is provided on the sealing box structure 100, and the through pipe 20 is snapped into the hook 15.
[0071] The guide pipe 20 is fixed by the hook 15 to avoid entanglement and friction with the internal components of the underwater cleaning machine 1, ensuring the stable transmission of the detection medium (water) and not affecting the detection of the detection element 30.
[0072] The hook 15 can provide support for the middle of the tube 20, preventing the middle section from sagging and ensuring that the outer end of the tube 20 extends accurately to the external detection area of the housing 200. Multiple hooks 15 can be provided, and multiple hooks 15 are arranged at intervals along the extension direction of the tube 20, so as to provide uniform support. When the tube 20 is a flexible tube, it can prevent the flexible tube from shaking and tangling, and ensure the stability of the tube 20 during installation.
[0073] In addition, the hook 15 can be integrally molded with the sealing box structure 100, such as by injection molding, without the need for additional heavy-duty fixing parts, which is suitable for the lightweight requirements of the underwater cleaning machine 1 and does not take up too much internal space.
[0074] Furthermore, the hook 15 forms a slot 15a, which is provided through the hook 15, and the through pipe 20 is installed in the slot 15a through the opening of the slot 15a.
[0075] The tube 20 does not need to be inserted from both ends of the slot 15a. It can be inserted by pressing it horizontally from the slot opening. It can be removed in the opposite direction when disassembling. No tools are required, making installation and disassembly simpler. It is suitable for operation in the narrow space inside the underwater cleaning machine 1.
[0076] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
