Description

Technical Field

[0001] This application relates to the field of water treatment equipment technology, and in particular to a water treatment device. Background Technology

[0002] To connect to external water supply systems and power sources, existing water treatment equipment often has exposed water inlets and power cables extending from the casing. These external connection structures are usually directly exposed on the outside of the casing, causing the overall outline of the equipment to protrude significantly outwards. This makes it difficult to install flush against walls or other planar structures, resulting in a considerable amount of space being occupied, which is particularly inconvenient in space-constrained installation environments.

[0003] Because the inlet, outlet, and power cord are typically located in different positions on the casing without integrated layout, the external piping and wiring are cluttered, affecting the overall appearance and increasing the complexity of installation and maintenance. Furthermore, existing water treatment equipment lacks consideration for the concealment of connecting components in its structural design. This causes interference between the water inlets and outlets and the power cord and the wall surface when the equipment is installed flush against the wall, preventing a tight fit. This structural limitation restricts the equipment's applicability in confined spaces and increases the difficulty of adjustments during installation, making it difficult to meet the demands for compact and integrated layouts in modern home or industrial settings.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] To connect to external water supply systems and power sources, existing water treatment equipment often has exposed water inlets and power cables extending from the casing. These external connection structures are usually directly exposed on the outside of the casing, causing the overall outline of the equipment to protrude significantly outwards. This makes it difficult to install flush against walls or other planar structures, resulting in a considerable amount of space being occupied, which is particularly inconvenient in space-constrained installation environments.

[0022] Because the inlet, outlet, and power cord are typically located in different positions on the casing without integrated layout, the external piping and wiring are cluttered, affecting the overall appearance and increasing the complexity of installation and maintenance. Furthermore, existing water treatment equipment lacks consideration for the concealment of connecting components in its structural design. This causes interference between the water inlets and outlets and the power cord and the wall surface when the equipment is installed flush against the wall, preventing a tight fit. This structural limitation restricts the equipment's applicability in confined spaces and increases the difficulty of adjustments during installation, making it difficult to meet the demands for compact and integrated layouts in modern home or industrial settings.

[0023] Based on this, see Figures 1 to 3 As shown, this utility model embodiment provides a water treatment device 10, which includes a shell structure 100, a water circuit board 200, and a power cord 300; the outer wall of the shell structure 100 is provided with a receiving groove 121, and the shell structure 100 is provided with a power hole communicating with the receiving groove 121; the water circuit board 200 is connected to the shell structure 100, and the water circuit board 200 is provided with an inlet 211 and an outlet 212 for connecting a water circuit interface 20, and the openings of the inlet 211 and the outlet 212 are both located in the receiving groove 121; the power cord 300 passes through the power hole, and the power cord 300 is at least partially located in the receiving groove 121.

[0024] In this embodiment, the water treatment device 10 has a receiving groove 121 on the outer wall of the housing structure 100, and the openings of the water inlet 211 and the water outlet 212 of the water circuit board 200 are arranged in the receiving groove 121. This allows the water circuit interface 20 connecting the water inlet 211 and the water outlet 212 to be housed in the receiving groove 121, preventing the water circuit interface 20 from protruding outward. At the same time, the power cord 300 passes through the power hole on the housing structure 100 that connects to the receiving groove 121, and is at least partially located in the receiving groove 121, thereby integrating the power cord 300 and the water circuit interface 20 into the same area for centralized arrangement.

[0025] In the water treatment device 10 of this embodiment, since the inlet 211, outlet 212, and power cord 300 are all integrated into the receiving tank 121, the protruding structures on the outside of the casing are effectively reduced, making the overall outer contour of the device smoother. This structural design avoids interference between the water interface 20 and the power cord 300 and the wall surface when installed close to the wall, thus facilitating the installation of the device close to the wall or other planar structures, significantly improving the installation adaptability in space-constrained environments. In addition, the integrated layout of the water circuit board 200 and the power cord 300 simplifies the routing of external pipes and lines, reducing the operational complexity during installation and maintenance.

[0026] Specifically, the housing structure 100 has an opening slot 123 communicating with the receiving groove 121. The water circuit plate 200 includes a plate body 210 and a crimping part 220. The water inlet 211 and the water outlet 212 are provided on the plate body 210, and the plate body 210 is connected to the housing structure 100. The crimping part 220 is accommodated in the opening slot 123, and the crimping part 220 and the inner wall of the opening slot 123 enclose each other to form a power hole. This power hole is used to accommodate and fix the power cord 300, so that the wiring path of the power cord 300 inside the equipment is constrained, avoiding poor contact or structural interference due to loosening or displacement. The shape of the crimping part 220 is adapted to the contour of the inner wall of the opening slot 123. The power hole formed by the two has a closed or semi-closed structure, which can limit and protect the power cord 300, and at the same time help to improve the neatness and compactness of the internal space of the whole machine.

[0027] The board body 210 can be detachably connected to the housing structure 100 via means such as clips or screws. Specifically, the clips can be elastic hooks located on the edge of the board body 210, which engage with corresponding slots on the housing structure 100 to achieve quick installation and removal; the screws can be secured by engaging pre-drilled mounting holes on the board body 210 with threaded holes on the housing structure 100. This detachable connection method facilitates later maintenance, replacement of the water circuit board 200, or inspection of internal wiring. Furthermore, during assembly, the connection method can be flexibly selected according to the actual installation space, improving assembly efficiency and adaptability.

[0028] During assembly, first, the power cord 300 is placed into the opening slot 123. Then, the board body 210 is connected to the housing structure 100, and the crimping part 220 is crimped onto the power cord 300, thus fixing the power cord 300 in the power hole. The crimping part 220 applies a certain clamping force to the power cord 300, keeping it stable in the power hole and preventing the power cord 300 from falling off or shifting due to vibration or external pulling during equipment operation. The crimping surface of the crimping part 220 can be designed to be arc-shaped or have anti-slip texture to increase the friction between it and the outer sheath of the power cord 300, improve the reliability of the fixation, and avoid damaging the cable insulation layer. In addition, the size of the power hole formed by the crimping part 220 and the inner wall of the opening slot 123 can be adapted to the outer diameter of the power cord 300 to ensure that the power cord 300 will not loosen after crimping, nor will its conductivity or mechanical strength be affected by excessive compression.

[0029] Finally, the water interface 20 is installed on the inlet 211 and outlet 212. The water interface 20 can be a quick-connect fitting, threaded fitting, or clamp fitting, etc., to connect to the external water supply pipeline to realize the introduction and export of water. The position layout of the inlet 211 and outlet 212 on the plate body 210 can be optimized according to the internal flow channel of the whole machine to reduce water flow resistance and improve water circuit sealing. Sealing rings or gaskets can be installed between the water interface 20 and the inlet 211 and outlet 212 to prevent water leakage.

[0030] At this point, the portions of the water inlet 20 and power cable 300 extending out of the water treatment equipment 10 are both located within the receiving tank 121 to facilitate the arrangement of pipelines and power cables 300. The receiving tank 121 provides centralized wiring space for the water inlet 20 and power cable 300, avoiding cluttered external pipelines and facilitating unified organization and connection by the user outside the equipment. The depth and width of the receiving tank 121 can be adjusted according to the actual size of the water inlet 20 and the number of power cables 300 used to meet the needs of different equipment models. In addition, the opening direction of the receiving tank 121 can be designed to face downwards or to the side to facilitate drainage or prevent foreign objects from entering, further improving the safety and environmental adaptability of the equipment.

[0031] Furthermore, the crimping part 220 has a crimping groove 221, which forms a power supply hole by enclosing the inner wall of the opening groove 123.

[0032] By engaging the crimping groove 221 with the opening groove 123, the stability of the power cord 300 can be improved, and damage to the outer surface of the power cord 300 can be avoided compared to planar contact. Specifically, the cross-sectional shape of the crimping groove 221 can be adapted to the outer contour of the power cord 300, such as being arc-shaped, semi-circular, or polygonal. Thus, when the crimping part 220 is closed with the housing structure 100, the crimping groove 221 and the opening groove 123 together form a covering clamping effect on the power cord 300, increasing the contact area and dispersing local compressive stress, effectively preventing the insulation layer from being crushed or deformed due to concentrated force. The depth of the crimping groove 221 can be adjusted according to the diameter of the power cord 300. For example, when the outer diameter of the power cord 300 is 4mm, the depth of the crimping groove 221 can be set to 1.5mm, 2mm, 2.5mm, or 3mm, depending on the actual assembly requirements and clamping force requirements. No single limit is set here. If the crimping groove 221 is too shallow, it cannot effectively limit the movement of the power cord 300 during use. If it is too deep, it may cause excessive crimping, which could compress the internal conductor, affecting conductivity or causing structural damage. Furthermore, the bottom of the crimping groove 221 can be provided with anti-slip textures or an elastic buffer layer (such as a rubber pad) to further improve clamping reliability and reduce wear on the outer sheath of the power cord 300. The crimping part 220 and the housing structure 100 can be fixedly connected by screws, clips, or welding to ensure that the crimping groove 221 and the opening groove 123 maintain stable alignment during long-term use, thereby maintaining continuous and effective fixation of the power cord 300.

[0033] Furthermore, the inlet 211 and the outlet 212 are located on opposite sides of the opening groove 123, respectively.

[0034] This design ensures that when the inlet 211 is connected to the external water inlet pipeline and the outlet 212 is connected to the external drainage pipeline, the extension directions of the water inlet and drainage pipelines are staggered, effectively preventing spatial interference. This layout significantly improves the freedom and operability of pipeline arrangement, especially in installation environments with limited space at the rear of the equipment. Furthermore, since the inlet 211 and outlet 212 are located on opposite sides of the opening slot 123, the distribution of the water interface 20 within the receiving slot 121 is more rational, helping to optimize internal space utilization and making the overall structure within the receiving slot 121 more compact, thus reserving more space for the arrangement of other functional components.

[0035] Specifically, the opening groove 123 can extend laterally along the housing structure 100. The inlet 211 is located at one end of the opening groove 123, and the outlet 212 is located at the opposite end. This layout not only facilitates the connection of external pipelines from both sides of the equipment, but also reduces the number of bends in the pipelines inside the housing structure 100, lowers water flow resistance, and improves fluid transmission efficiency. In practical applications, the specific positions of the inlet 211 and outlet 212 can be adaptively adjusted according to the overall structure of the housing structure 100, the lead-out position of the power cord 300, and the external installation environment. As long as they are located on opposite sides of the opening groove 123, the above-mentioned technical effects can be achieved. For example, the inlet 211 can be located on the left side of the opening groove 123, and the outlet 212 on the right side; or the inlet 211 can be located on the front side, and the outlet 212 on the rear side. The specific location is determined according to the installation orientation of the housing structure 100 and the pipeline routing requirements, and no single limitation is made here.

[0036] In one embodiment, the housing structure 100 has a mounting groove 124, which is connected to an opening groove 123, and the opening groove 123 is used for the power line 300 to pass through; the water circuit board 200 also includes a cover portion 230, which is connected to the crimping portion 220, and the cover portion 230 is at least partially located in the mounting groove 124.

[0037] By providing the mounting slot 124, when installing the power cord 300, the power cord 300 can be inserted from the mounting slot 124 into the opening slot 123. After the power cord 300 is installed, the mounting slot 124 can be sealed by the cover part 230. At this time, the mounting slot 124, in cooperation with the cover part 230, positions the water circuit board 200 and ultimately ensures the sealing performance of the housing structure 100. This structural design integrates the power cord 300's entry path with the sealing structure of the housing structure 100, avoiding the damage to the housing's sealing performance caused by opening additional cable channels.

[0038] Specifically, the shape of the mounting groove 124 can be adapted to the contour of the cover portion 230. For example, the mounting groove 124 can be set as a rectangular, circular, or polygonal groove, and the cover portion 230 is correspondingly set as a matching protrusion structure to achieve a good fitting and positioning effect. A sealing ring or sealing adhesive layer can be further provided between the cover portion 230 and the mounting groove 124 to enhance the sealing performance. The cover portion 230 and the pressing portion 220 can be an integrally formed structure, or they can be connected by fasteners. The fasteners can be screws, pins, or snap-fit ​​structures. Screw connections facilitate disassembly and maintenance, while snap-fit ​​structures facilitate quick assembly. When screws are used as fasteners, threaded holes can be opened on the cover portion 230, and countersunk holes or through holes can be provided at corresponding positions on the housing structure 100 to achieve a stable connection without protruding from the surface.

[0039] It should be noted that the depth of the mounting groove 124 can be set according to the thickness of the cover portion 230. For example, the depth of the mounting groove 124 can be 1mm, 2mm, or 3mm, depending on the actual design requirements, and is not limited here. If the depth of the mounting groove 124 is too small, the cover portion 230 may not be fully embedded, affecting the positioning accuracy and sealing effect; if the depth is too large, it may weaken the structural strength of the housing structure 100, or cause the cover portion 230 to have loose gaps after installation, thus affecting the overall sealing performance.

[0040] Furthermore, the width of the opening slot 123 should be slightly larger than the outer diameter of the power cord 300 to ensure that the power cord 300 can pass through smoothly, while avoiding excessive gaps that could cause sealing failure, and balancing assembly convenience and sealing performance. The cover portion 230, while sealing the mounting slot 124, also limits the position of the power cord 300 at the opening slot 123, preventing displacement or pulling of the power cord 300 during use, thereby improving the overall structural reliability.

[0041] The overall structure is compact and does not require additional independent cable sealing components, which simplifies the assembly process. At the same time, the cooperation between the cover 230 and the mounting groove 124 not only achieves the installation and positioning of the water circuit board 200, but also effectively maintains the sealing integrity of the shell structure 100.

[0042] Furthermore, the opening of the mounting groove 124 is provided with a guide slope 1241, which is used to drive the cover part 230 into the mounting groove 124.

[0043] In this embodiment, the guide ramp 1241 allows the cap 230 to gradually slide into the mounting groove 124 along the inclined surface of the guide ramp 1241 as it approaches the mounting groove 124, thus avoiding problems such as the cap 230 getting stuck or failing to assemble smoothly due to misalignment. The inclination angle of the guide ramp 1241 can be adjusted according to actual assembly requirements. For example, the inclination angle can be set to 15°, 30°, 45°, or 60°, specifically determined based on the outer contour of the cap 230, the installation space, and ease of operation, and is not limited to a single value here. If the inclination angle is too small, the guiding effect will be weakened, and it may not be able to effectively guide the cap 230 into the mounting groove 124; if the inclination angle is too large, the guide ramp 1241 may occupy too much space, affecting the overall structural compactness.

[0044] Therefore, the guide ramp 1241 can guide and position the power cord 300 during installation, improving the ease and accuracy of installation. In actual assembly, the power cord 300 is typically connected to or integrated with the cover 230. When the cover 230 is smoothly inserted into the mounting groove 124 by the guide ramp 1241, the power cord 300 is simultaneously guided to the preset wiring path or connection position, thereby reducing the need for manual adjustment of the power cord 300's routing and lowering the risk of assembly errors. Furthermore, the guide ramp 1241 can also limit the lateral displacement of the cover 230 during assembly to a certain extent, allowing the interface end of the power cord 300 to more accurately align with the corresponding electrical connection terminal, improving the overall consistency and reliability of the assembly. The surface of the guide ramp 1241 can be smoothed or made of a low-friction coefficient material to further reduce the resistance during the sliding of the cover 230, improving assembly smoothness.

[0045] Specifically, a positioning groove 122 is provided inside the housing structure 100, and the power cord 300 is engaged with the positioning groove 122.

[0046] The positioning groove 122 can be located on the inner wall of the internal space of the housing structure 100. During installation, the power cord 300 can be secured by the positioning groove 122 to position the power cord 300. This structural design effectively limits the position of the power cord 300 inside the housing structure 100, preventing problems such as loose wiring, short circuits, or wear caused by the power cord 300 shaking or shifting during equipment operation or transportation, thereby improving the overall electrical safety and structural stability of the equipment.

[0047] The cross-sectional shape of the positioning groove 122 can be adapted to the outer contour of the power cord 300, for example, it can be U-shaped, V-shaped, semi-circular, or rectangular, to achieve stable holding of the power cord 300. In some specific embodiments, the inner wall of the positioning groove 122 can be provided with an elastic buckle structure or anti-slip texture to further enhance the clamping force on the power cord 300 and prevent it from coming out under vibration. In addition, the opening direction of the positioning groove 122 can face the assembly direction of the housing structure 100, which facilitates the insertion of the power cord 300 along a preset path during assembly and improves assembly efficiency.

[0048] The housing structure 100 can be manufactured using methods such as injection molding, die casting, or machining. The positioning groove 122 can be integrally formed with the housing structure 100, or it can be formed through subsequent processing. Integral molding helps reduce the number of parts, lower manufacturing costs, and improve the overall structural integrity; while subsequent processing is suitable for applications requiring high positioning accuracy, facilitating fine-tuning according to the actual dimensions of the power cable 300. The material of the positioning groove 122 can be consistent with that of the housing structure 100, such as engineering plastics, aluminum alloys, or stainless steel, depending on the specific conditions of the equipment's operating environment, strength requirements, and cost control.

[0049] The overall design of this structure is simple and requires no additional fasteners or complicated installation steps to reliably position the power cord 300 inside the housing structure 100. This simplifies the assembly process and improves the neatness and maintainability of the internal wiring of the product.

[0050] In one embodiment, the water treatment device 10 further includes a sealing cover 400, which is detachably connected to the water circuit board 200 and used to cover the inlet 211 and / or the outlet 212.

[0051] By using a sealing cap 400 to cooperate with the water circuit board 200, the inlet 211 and / or outlet 212 of the water circuit board 200 can be sealed by the sealing cap 400 when the water circuit interface 20 is not installed, for transportation and dust prevention. The detachable connection between the sealing cap 400 and the water circuit board 200 can be achieved by threaded connection, snap-fit ​​connection, magnetic connection, or interference fit. For example, the inner wall of the sealing cap 400 can be provided with internal threads, which can cooperate with the external threads on the outer periphery of the inlet 211 or outlet 212 to achieve threaded connection; or the edge of the sealing cap 400 can be provided with elastic snaps, which can cooperate with the corresponding slot structure on the water circuit board 200 to achieve snap-fit ​​connection. The above connection methods allow users to quickly remove the sealing cap 400 when the water circuit interface 20 needs to be installed, while effectively preventing dust and foreign objects from entering the interior of the water circuit board 200 when not in use, avoiding contamination of the water circuit channel or affecting the sealing performance when the water circuit interface 20 is subsequently installed.

[0052] Specifically, the sealing cap 400 can simultaneously cover both the inlet 211 and the outlet 212, or it can cover only one of them. When the water treatment equipment 10 is under transportation, stored, or temporarily not connected to the water supply / drainage system, sealing at least one opening with the sealing cap 400 can effectively prevent external contaminants from entering the internal flow channels of the water circuit board 200, thereby ensuring the cleanliness of the equipment's interior and the reliability of its subsequent use. The sealing cap 400 can be made of corrosion-resistant materials with a certain degree of elasticity and sealing performance, such as silicone, rubber, or engineering plastics, to ensure that it maintains a good sealing effect after multiple disassemblies and reassemblies. In addition, a sealing ring or sealing gasket can be provided at the contact points between the sealing cap 400 and the inlet 211 and / or the outlet 212 to further improve the sealing performance and prevent seal failure due to vibration or temperature and humidity changes during transportation.

[0053] Furthermore, the water treatment equipment 10 also includes a detection switch 500, which is connected to the housing structure 100 and is used to acquire the position signal of the sealing cover 400.

[0054] Specifically, the detection switch 500 can be positioned appropriately inside or outside the housing structure 100, enabling it to interact with the sealing cover 400 through mechanical contact, photoelectric induction, magnetic induction, or other forms of signal exchange when the cover is closed or open, thereby accurately determining whether the sealing cover 400 is in the correct installation position. Specifically, the detection switch 500 can be a microswitch, Hall sensor, photoelectric switch, or proximity switch, selected according to the actual structural layout and control logic requirements. For example, when using a microswitch, the trigger terminal of the microswitch can be pressed when the sealing cover 400 is closed, causing it to output a closed signal; when the sealing cover 400 is open or not fully installed, the microswitch resets and outputs an open signal. Alternatively, when using a Hall sensor, a permanent magnet can be placed on the sealing cover 400; when the sealing cover 400 approaches the Hall sensor to a set distance, the Hall sensor senses the change in the magnetic field and outputs a corresponding level signal.

[0055] By configuring the detection switch 500 in conjunction with the sealing cover 400, the detection switch 500 can control the water treatment equipment 10 to start only after detecting that the sealing cover 400 has separated from the water circuit board 200. This control logic allows the main control module of the water treatment equipment 10 to receive the position signal output by the detection switch 500 and determine whether the equipment is allowed to enter the operating state. For example, when the detection switch 500 outputs a signal indicating that the sealing cover 400 is not fully closed or is in a disassembled state, the main control module will prohibit the water pump, solenoid valve, or other actuators from starting, thereby preventing the water treatment equipment 10 from accidentally starting before installation is complete. This design effectively prevents safety hazards such as water leakage, water circuit connection failure, or exposure of internal components caused by improper installation of the sealing cover 400, improving the safety and reliability of the equipment. Furthermore, during maintenance or filter replacement operations, if the sealing cover 400 is opened, the detection switch 500 can also immediately report the status change, causing the equipment to automatically enter a shutdown protection state, further ensuring user operational safety.

[0056] In one embodiment, the housing structure 100 has a connection hole 125, and the sealing cover 400 includes a sealing part 410 and a top part 420. The sealing part 410 is used to seal the water inlet 211 and / or the water outlet 212, and the top part 420 passes through the connection hole 125 and is used to contact the detection switch 500.

[0057] Specifically, the sealing part 410 can be made of an elastic sealing material (such as silicone, fluororubber, etc.), and its shape is adapted to the end face contour of the inlet 211 and / or outlet 212, or adapted to the water interface 20 installed on the inlet 211 and / or outlet 212, so as to form a reliable sealing interface after the sealing cover 400 is installed in place, preventing liquid leakage from the interface. The top 420 can be integrally formed with the sealing part 410, or it can be fixedly connected to the sealing part 410 by fasteners (such as screws, clips, etc.); among them, the screw connection is convenient for disassembly and maintenance, while the clip connection can simplify the assembly process and improve assembly efficiency.

[0058] In this embodiment, the detection switch 500 can be a micro switch and is located inside the housing structure 100. When the sealing cover 400 is connected to the housing structure 100, the abutment 420 can extend into the housing structure 100 through the connection hole 125 and contact the detection switch 500 to realize the detection function of the detection switch 500. Specifically, the end of the abutment 420 can be configured as a flat, spherical, or conical structure to adapt to the trigger end face shape of the detection switch 500, ensuring that the detection switch 500 can be stably triggered when the sealing cover 400 is fully installed. When the sealing cover 400 is not installed or is not fully installed, the abutment 420 cannot contact or is insufficient to trigger the detection switch 500. At this time, the detection switch 500 is in the off state, and the device can determine that the sealing cover 400 is not in place, thereby prohibiting the device from starting or issuing a warning signal, improving the safety and reliability of use. Furthermore, the inner diameter of the connecting hole 125 can be slightly larger than the outer diameter of the abutment 420 to allow for certain assembly tolerances. A sealing ring or sealant can be installed on the inner wall of the connecting hole 125 to prevent external liquids or impurities from entering the housing structure 100 through the connecting hole 125 and affecting the normal operation of the detection switch 500. The installation position of the detection switch 500 can be adjusted according to the stroke length of the abutment 420 to ensure that the abutment 420 can accurately trigger the contacts of the detection switch 500 when the sealing cover 400 is tightened or snapped into place, achieving a reliable position detection function.

[0059] Furthermore, the water circuit board 200 has an installation cavity 213, and the detection switch 500 is housed in the installation cavity 213.

[0060] By providing a mounting cavity 213 on the water circuit board 200, a stable mounting space can be provided for the detection switch 500. The inner wall of the mounting cavity 213 is adapted to the outer contour of the detection switch 500, thereby positioning and limiting the detection switch 500 during assembly, effectively preventing the detection switch 500 from shifting or loosening during installation or use. Specifically, the shape of the mounting cavity 213 can be designed according to the shape of the detection switch 500, for example, it can be a rectangular, circular, or polygonal cavity. Its inner wall can be provided with auxiliary positioning structures such as buckles, bosses, or grooves to further improve the stability of the detection switch 500 installation.

[0061] In the actual assembly process, the detection switch 500 can be embedded into the mounting cavity 213 first, forming a pre-assembled component. This component is then installed onto the housing structure 100, simplifying the assembly process, reducing assembly steps, and improving assembly efficiency. Furthermore, since the detection switch 500 is integrated inside the water circuit board 200, it effectively reduces external space occupation, facilitating a more compact overall design. It also provides some protection for the detection switch 500, preventing it from being affected by external water flow, dust, or mechanical impact, thus improving its operational stability and service life. The depth, width, and height of the mounting cavity 213 can be adapted to the specific model of the selected detection switch 500, determined according to actual design requirements, and are not limited to a single dimension.

[0062] In one embodiment, the housing structure 100 includes an outer shell 110 and a bottom plate 120. The outer shell 110 is detachably connected to the bottom plate 120, the receiving groove 121 is located at the bottom of the bottom plate 120, and the water channel plate 200 is detachably connected to the bottom plate 120.

[0063] The detachable connection facilitates the assembly, disassembly, and manufacturing of the housing structure 100. Specifically, the detachable connection between the outer shell 110 and the base plate 120 can be achieved using any one or more combinations of screws, snap-fit ​​fasteners, magnetic connectors, or plug-in structures. For example, when using screws, multiple threaded holes can be provided around the periphery of the base plate 120, corresponding to through holes on the side wall or bottom edge of the outer shell 110. Screws are screwed through the through holes and into the threaded holes for fastening. When using snap-fit ​​fasteners, hooks or slots can be provided on the base plate 120, and corresponding slots or hooks can be provided on the outer shell 110. The fastening is achieved by pressing or sliding. These connection methods facilitate the quick disassembly of the outer shell 110 during assembly or maintenance, allowing for the inspection or replacement of internal components. They also promote modular production and improve assembly efficiency.

[0064] During assembly, the water circuit board 200 and related components can be installed on the base plate 120 first, and then the outer casing 110 can be placed on the base plate 120. This assembly sequence helps to obtain more operating space when installing the water circuit board 200 and avoids the outer casing 110 from obstructing or interfering with the installation process. The detachable connection between the water circuit board 200 and the base plate 120 can also be achieved by screws, clips, or guide rail sliding. For example, positioning posts or limiting grooves can be set on the base plate 120, and corresponding positioning holes or protrusions can be set on the water circuit board 200 to achieve quick positioning and stable installation. In addition, the water circuit board 200 integrates a water circuit interface 20, which connects to the external water supply pipeline. By fixing the water circuit board 200 to the base plate 120 first, the positional accuracy of the water circuit interface 20 can be ensured, avoiding misalignment of the interface due to assembly errors of the outer casing 110.

[0065] The receiving groove 121 is preferably located at the bottom edge of the base plate 120 so as to prevent the water inlet 20 and power cord 300 from being exposed after the water treatment equipment 10 is installed on the countertop. Specifically, the receiving groove 121 can be located at the rear edge or side edge of the base plate 120, and its shape can be rectangular, arc-shaped, or polygonal to accommodate the routing of the water inlet 20 and power cord 300. The depth of the receiving groove 121 can be designed according to the protrusion height of the water inlet 20 and the bending radius of the power cord 300. For example, the depth can be set to 10mm, 15mm, 20mm, or 25mm, depending on the actual installation space and cable specifications, and is not limited to a single depth. When the depth of the receiving groove 121 is too small, it may not be able to completely hide the water inlet 20 and power cord 300, affecting the overall aesthetics and potentially causing excessive cable bending; when the depth is too large, it may weaken the structural strength of the base plate 120 or increase the overall thickness, which is not conducive to the compact design of the equipment. By setting the receiving slot 121 at the bottom edge of the base plate 120, the water inlet 20 and the power cord 300 can be naturally accommodated under the countertop or inside the cabinet when the equipment is embedded in the countertop, which not only improves the appearance but also facilitates the user's later maintenance operations.
