Description

Technical Field

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

[0002] With the advancement of technology, people have developed diverse needs for domestic water. Water treatment equipment can treat the input water, such as adjusting the water temperature and quality to meet user requirements, before outputting the treated water to users, greatly facilitating their lives. Currently, most common water treatment equipment uses a metal plate base, resulting in a relatively heavy overall weight and inconvenient transportation.

[0003] In order to provide heat exchange medium to users, water treatment equipment may also store a certain amount of heat exchange medium in a hot tank. However, due to the good thermal conductivity of the metal plate base, the heat exchange medium stored in the hot tank is easily lost through the metal plate base, which greatly affects the heat preservation performance of the water treatment equipment.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] With the advancement of technology, people have developed diverse needs for domestic water. Water treatment equipment can treat the input water, such as adjusting the water temperature and quality to meet user requirements, before outputting the treated water to users, greatly facilitating their lives. Currently, most common water treatment equipment uses a metal plate base, resulting in a relatively heavy overall weight and inconvenient transportation.

[0025] In order to provide heat exchange medium to users, water treatment equipment may also store a certain amount of heat exchange medium in a hot tank. However, due to the good thermal conductivity of the metal plate base, the heat exchange medium stored in the hot tank is easily lost through the metal plate base, which greatly affects the heat preservation performance of the water treatment equipment.

[0026] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0027] See Figure 1 , 2 5, Figure 1 This is a schematic diagram of the assembly structure of an embodiment of the water treatment equipment of this application. Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure shown in section AA. Figure 5 This is a schematic diagram of the assembly structure of another embodiment of the water treatment equipment of this application. A specific embodiment of this application provides a water treatment equipment 1, including a main body 2 and a plastic base 5. The main body 2 includes a heat tank assembly 3 and a water system 4 connected to each other. The heat tank assembly 3 includes a tank body 31, which has a heat exchange medium cavity 311 for containing a heat exchange medium. The plastic base 5 is supported at the lower end of the main body 2 and is fixedly connected to the heat tank assembly 3.

[0028] Water treatment equipment 1 refers to equipment that treats input water to meet user needs, typically used in residential, commercial, or industrial settings. Its water treatment methods may include at least one of filtration, heating, cooling, and softening. Specifically, water treatment equipment 1 can be a water purifier, water heater, water softener, chiller, etc.

[0029] The main body 2 refers to the core part of the water treatment equipment 1, including major functional modules such as the heating tank assembly 3 and the water system 4. The water input to the water treatment equipment 1 flows and is treated within the main body 2. For example, in an instant hot water dispenser, the main body 2 may include structures such as a thick-film heater, a water pump, a valve body, and a water circuit board. The heating tank assembly 3 is the component in the equipment used to store and heat the heat exchange medium, and is a key part in the preparation of hot water. The tank 31 may be equipped with a heating element, or the tank 31 may be thermally connected to the heating element. The water system 4 is the system in the equipment that controls the flow of water, and may include structures such as an inlet, an outlet, pipes, valves, and a pump. The heat exchange medium cavity 311 is the cavity in the tank 31 used to contain the heat exchange medium, which is the substance in the main body 2 used to store and transfer heat, and can be liquids such as water and oil, or gases.

[0030] The plastic base 5 is a base made of plastic material, used to support and fix the main body of the equipment 2. It features lightweight, corrosion resistance, and good insulation. The plastic base 5 can be made of polypropylene plastic, polycarbonate plastic, etc.

[0031] In the structure provided in this specific embodiment, a plastic base 5 is used to support the main body 2 of the equipment. Taking advantage of the fact that plastic is lighter than metal, the weight of the entire water treatment equipment 1 is reduced, making it easier to transport. At the same time, the thermal conductivity of plastic is also lower than that of metal. Using a plastic base 5 can reduce heat loss of the heat exchange medium inside the tank 31, thereby improving the heat preservation performance of the water treatment equipment 1. This effectively solves the problems of heavy weight, inconvenient transportation, and poor heat preservation performance of the water treatment equipment 1 caused by a metal base.

[0032] like Figures 1-5 , Figure 7 As shown, Figure 3 yes Figure 1 A schematic diagram of the cross-sectional structure shown in section BB. Figure 4 yes Figure 3 A magnified structural diagram of region C in the middle. Figure 6 This is a schematic block diagram of the water circuit structure of an embodiment of the water treatment equipment of this application. Figure 7 yes Figure 5 The cross-sectional view shown in Figure DD is a schematic diagram. In a specific embodiment of this application, the hot tank assembly 3 further includes a hot tank insulation sleeve 32, which is sleeved on the outer periphery of the tank body 31, and the bottom end of the hot tank insulation sleeve 32 is connected to the plastic base 5.

[0033] The hot tank insulation sleeve 32 is a component used to wrap around the outside of the tank body 31 to reduce its heat loss. It is usually made of a material with excellent thermal insulation properties and its shape matches the tank body 31. For example, the hot tank insulation sleeve 32 can be polyurethane foamed directly on the outside of the tank body 31, or it can be a pre-formed, hollow cylindrical insulation cotton or insulation shell.

[0034] Specifically, the bottom of the hot water tank insulation sleeve 32 is mechanically fixed to the plastic base 5. The connection method can include snap-fit ​​connection, screw connection, adhesive bonding, or fixation by a support structure on the plastic base 5.

[0035] In the structure provided in this specific embodiment, the outer periphery of the tank body 31 is wrapped by a heat exchange sleeve 32, and the plastic base 5 and the bottom of the tank body 31 are isolated by the heat exchange sleeve 32. Through the double cooperation of the heat exchange sleeve 32 and the plastic base 5, a complete heat preservation system is provided for the heat exchange assembly 3, which greatly reduces the heat loss of the heat exchange medium through the outer surface of the tank body 31. At the same time, the thermal conductivity between the tank body 31 and the plastic base 5 is reduced, which can reduce the probability of deformation and aging of the plastic base 5 under the high temperature of the tank body 31. The heat exchange sleeve 32 not only plays a role in heat preservation, but also serves as a structural component, integrating the tank body 31, the heat exchange sleeve 32, and the plastic base 5 into a more stable whole. This helps to reduce vibration during equipment operation and improve the reliability of the structure.

[0036] See Figure 4 , Figure 7 In one specific embodiment of this application, the hot tank insulation sleeve 32 is provided with one of a limiting cylinder 323 and a limiting protrusion 51, and the plastic base 5 is provided with the other of the limiting cylinder 323 and the limiting protrusion 51. The limiting protrusion 51 is sleeved inside the limiting cylinder 323, thereby snapping and fixing the bottom end of the hot tank insulation sleeve 32 to the plastic base 5.

[0037] The limiting cylinder 323 is a cylindrical structure that restricts the position of the limiting protrusion 51. It is usually a hollow cylinder or square tube. Its internal space is used to accommodate and guide the insertion of the limiting protrusion 51. It can provide precise positioning for the heat-insulating sleeve 32 of the hot can and the plastic base 5, and limit the relative displacement of the heat-insulating sleeve 32 of the hot can and the plastic base 5 in the horizontal direction.

[0038] The limiting protrusion 51 is a protruding structure that limits the position, and its outer contour shape can match the inner cavity of the limiting cylinder 323. For example, the limiting protrusion 51 can be cylindrical, square, or rod-shaped with an inverted buckle. The function of the limiting protrusion 51 is to be inserted into the corresponding limiting cylinder 323 to achieve positioning and locking fixation between the hot tank insulation sleeve 32 and the plastic base 5.

[0039] In the structure provided in this specific embodiment, the nested structure of the limiting cylinder 323 and the limiting protrusion 51 allows the limiting cylinder 323 to serve as a guide and positioner. During assembly, this reduces the difficulty of aligning the hot tank insulation sleeve 32 with the plastic base 5, while also preventing mistake-proofing and significantly improving the assembly efficiency of the water treatment equipment 1. The tight mechanical interlock between the limiting cylinder 323 and the limiting protrusion 51 effectively resists vibrations generated during transportation or use of the water treatment equipment 1, reducing the probability of loosening between the hot tank assembly 3 and the plastic base 5, and improving the reliability and durability of the water treatment equipment 1. Furthermore, the structure of the limiting cylinder 323 and the limiting protrusion 51 eliminates the need for additional connecting parts such as screws, nuts, and clamps, reducing the number of parts, simplifying the mold structure and assembly process, thereby reducing material and assembly costs.

[0040] like Figure 4 , Figure 7 As shown in a specific embodiment of this application, the plastic base 5 may be provided with multiple first positioning protrusions 52, and the hot can insulation sleeve 32 is provided with multiple first positioning grooves 324. The first positioning protrusions 52 and the first positioning grooves 324 are provided in a one-to-one correspondence, and the first positioning protrusions 52 are embedded in the first positioning grooves 324.

[0041] Optionally, the heat-insulating sleeve 32 of the hot can may be provided with multiple first positioning protrusions 52, and the plastic base 5 may be provided with multiple first positioning grooves 324. The first positioning protrusions 52 and the first positioning grooves 324 are provided in a one-to-one correspondence, and the first positioning protrusions 52 are embedded in the first positioning grooves 324.

[0042] The first positioning ridge 52 can refer to a continuous, elongated protrusion with a cross-section that can be rectangular, trapezoidal, semi-circular, etc. For example, the first positioning ridge 52 can be several radially or parallelly distributed protrusions on the bottom surface of the plastic base 5 or the heat exchanger sleeve 32. The first positioning groove 324 matches the shape and size of the first positioning ridge 52, and is a recess or groove used to accommodate the first positioning ridge 52. The number, position, and shape of the first positioning ridges 52 perfectly match the first positioning grooves 324; for every first positioning ridge 52, there is necessarily a first positioning groove 324 waiting for it to be inserted.

[0043] In the structure provided in this specific embodiment, multiple radially or parallelly arranged first positioning protrusions 52 and first positioning grooves 324 are interlocked, effectively preventing relative rotation between the hot tank insulation sleeve 32 and the plastic base 5, and limiting the horizontal relative displacement between the hot tank insulation sleeve 32 and the plastic base 5. The interlocking of the first positioning protrusions 52 and the first positioning grooves 324 greatly increases the contact area between the hot tank insulation sleeve 32 and the plastic base 5, making the connection between the hot tank insulation sleeve 32 and the plastic base 5 more robust. This allows for better stress distribution while bearing forces in various directions, reducing the probability of local deformation of the hot tank insulation sleeve 32 and the plastic base 5, and enhancing the overall structural stability of the water treatment equipment 1.

[0044] In addition, the first positioning protrusion 52 and the first positioning groove 324 serve as auxiliary guides for each other, allowing the first positioning protrusion 52 to be easily aligned with the first positioning groove 324 and slid in, thus achieving rapid positioning of the two and ensuring the correct installation of the hot tank insulation sleeve 32 and the plastic base 5, thereby improving the assembly efficiency and accuracy of the water treatment equipment 1.

[0045] like Figure 7 As shown, furthermore, the multiple first positioning protrusions 52 can be arranged in a crisscrossing manner, and the multiple first positioning grooves 324 can also be arranged in a crisscrossing manner. The crisscrossing arrangement can better withstand forces in various directions while dispersing stress, which can reduce the probability of local deformation of the heat tank insulation sleeve 32 and the plastic base 5, and enhance the overall structural stability of the water treatment equipment 1.

[0046] See Figure 2 In one specific embodiment of this application, the surface of the hot tank insulation sleeve 32 facing away from the tank body 31 is provided with a wire passage groove 325, the water treatment equipment 1 includes a power cord 81, the power cord 81 is accommodated in the wire passage groove 325, the plastic base 5 is provided with a limiting wire groove 55, one end of the power cord 81 is connected to the water system 4, and the other end of the power cord 81 is fixed in the limiting wire groove 55.

[0047] The cable guide 325 is a groove, channel, or conduit designed on the surface of an object, specifically for guiding and accommodating cables such as the power cord 81, allowing them to pass neatly and orderly through a specific area. For example, the cable guide 325 may be a strip-shaped groove engraved on the outer wall of the heat exchanger insulation sleeve 32. The power cord 81 is a conductor connecting the water treatment equipment 1 to an external power source (such as a household socket) for transmitting electrical energy. The power cord 81 consists of an inner metal conductor and an outer insulating sheath. The limiting cable guide 55 is used to fix and limit a section or end of the power cord 81, thereby preventing it from moving or loosening. Specifically, the limiting cable guide 55 may have a snap-fit, clip, or other structure to clamp the power cord 81.

[0048] In the structure provided in this specific embodiment, the cable tray 325 and the limiting cable tray 55 provide a dedicated routing path and fixing points for the power cable 81, preventing the power cable 81 from being scattered randomly inside the water treatment equipment 1. This prevents the power cable 81 from interfering with or being worn by moving parts or sharp edges within the water treatment equipment 1, thereby eliminating the risk of short circuits and leakage caused by damage to the insulation layer of the power cable 81, significantly improving electrical safety. The clear routing path formed by the cable tray 325 and the limiting cable tray 55 allows production line workers to quickly and accurately place the power cable 81 during assembly, improving the assembly efficiency of the water treatment equipment 1 and ensuring the consistency of the water treatment equipment 1 products. During subsequent maintenance, maintenance personnel can also clearly understand the routing of the power cable 81, improving the efficiency of maintenance and repair.

[0049] Furthermore, since the cable tray 325 and the limiting cable tray 55 are located on the side of the hot tank insulation sleeve 32 away from the tank body 31, the hot tank insulation sleeve 32 is isolated between the tank body 31 and the power cord 81. This can reduce the impact of heat and water in the tank body 31 on the power cord 81, reduce the probability of the power cord 81 aging or breaking due to heat, and also reduce the probability of the power cord 81 burning out or short-circuiting when exposed to water. This can extend the service life of the power cord 81 and improve the long-term safety and durability of the water treatment equipment 1.

[0050] Optionally, a heat insulation sleeve may be fitted over the power cord 81. The heat insulation sleeve is a protective structure that is fitted over the power cord 81 to block heat transfer. The heat insulation sleeve is usually made of high-temperature resistant and low thermal conductivity materials, such as fiberglass tubing, silicone tubing, ceramic fiber braided tubing, etc.

[0051] In the structure provided in this specific embodiment, on the basis of the heated tank insulation sleeve 32, the addition of a heat insulation sleeve can further provide an active and additional heat insulation barrier for the power cord 81, thereby ensuring that it operates within a safe temperature range, greatly extending the service life of the power cord 81, and further improving the long-term safety and durability of the water treatment equipment 1.

[0052] Optionally, see Figure 5 The water system 4 may include a circuit board 83, and a power line 81 connects to the circuit board 83. The circuit board 83 can be a PCB (Printed Circuit Board), which serves as the support for various electronic components in the water treatment equipment 1 and the carrier for electrical connections between these components. The circuit board 83 connects various electronic components together through copper foil traces, forming a specific circuit functional module that functions as a control, drive, or signal processing unit in the water treatment equipment 1. These electronic components may include chips, resistors, capacitors, interfaces, etc.

[0053] For example, circuit board 83 can be responsible for receiving user water dispensing button commands, controlling the heating power of the water body, controlling the start and stop of the water pump in water system 4, controlling the opening and closing of valves in water system 4, and displaying water temperature and working status. Power cord 81 can be connected to the power input interface on circuit board 83 by soldering, plugging in terminals, etc., so as to introduce external power into circuit board 83 and then power various electronic components in water treatment equipment 1.

[0054] like Figure 2 , Figure 3 , Figure 6 As shown in a specific embodiment of this application, the heat exchange tank insulation sleeve 32 includes a heat exchange tank sleeve 322 and an insulation cover 321. The water system 4 includes a water circuit board assembly 41, which has a water supply channel 411 and a heat exchange water inlet channel 412. One end of the heat exchange water inlet channel 412 is connected to a water source, and the other end is connected to the tank body 31. One end of the water supply channel 411 is connected to a water source, and the other end is used to output water. The heat exchange tank sleeve 322 has a receiving groove 326, and the tank body 31 is disposed in the receiving groove 326. The insulation cover 321 is disposed on the opening of the receiving groove 326. The water circuit board assembly 41 is disposed on the side of the insulation cover 321 away from the receiving groove 326. The wire channel 325 is located at the end of the heat exchange tank sleeve 322 away from the opening of the receiving groove 326.

[0055] The hot tank sleeve 322 is the main body of the hot tank insulation sleeve 32. It is a sleeve-shaped structure with a receiving groove 326, which can be made of insulation material 82. Its main function is to wrap the sides and bottom of the tank body 31 with the receiving groove 326 to provide heat insulation protection. The insulation cover 321 is the top cover of the hot tank insulation sleeve 32, also made of insulation material 82. It covers the groove of the hot tank sleeve 322 and together with the hot tank sleeve 322, forms a complete insulation cavity, completely wrapping the tank body 31. At the same time, the insulation cover 321 also has the function of installing the water circuit board assembly 41.

[0056] The water circuit board assembly 41 is a plate-shaped or block-shaped component integrating various water circuit elements, and can be made of engineering plastics such as POM (polyoxymethylene). The water circuit board assembly 41 achieves water flow switching, distribution, and connection through precision-machined water passage 411 and heat exchange inlet water passage 412. Valves, pump bodies, connectors, and other structures can be directly installed on the water circuit board assembly 41. Water passage 411 is the flow channel in the water circuit board assembly 41 used to deliver treated water for final use by the user. Heat exchange inlet water passage 412 is the flow channel in the water circuit board assembly 41 specifically used to transport the heat exchange medium to be heated to the tank 31. Exemplarily, the heat exchange inlet water passage 412 and water passage 411 can be connected to the same water source.

[0057] In the structure provided in this specific embodiment, the core functions of the complex water system 4 are integrated onto the water circuit board assembly 41, which is then tightly connected to the hot tank assembly 3 via the insulated top cover 321. This makes the internal structure of the water treatment equipment 1 highly compact and orderly, reducing complex pipe connections and facilitating assembly and maintenance. By "mounting" the water circuit board above the hot tank assembly 3, the unused space above the tank 31 is effectively utilized, significantly reducing the installation space required for the water treatment equipment 1 and making its structure more compact. The insulated top cover 321 also acts as a heat insulation barrier, separating the high-temperature tank 31 from the temperature-sensitive plastic parts and electronic valves in the water circuit board assembly 41. This prevents heat from the tank 31 from directly radiating or conducting to the water circuit board, avoiding problems such as aging, deformation, and malfunction of electronic components due to prolonged heating. Meanwhile, the heat-insulating top cover 321 serves as an installation platform for the water circuit board assembly 41, providing a flat and stable installation base for the water circuit board assembly 41, effectively resisting vibration and ensuring the sealing of the connection between the water circuit board assembly 41 and the tank body 31.

[0058] In addition, the cable tray 325 is located on the side away from the heat insulation cover 321, which ensures that the power cable 81 can be introduced from the bottom of the equipment and routed along the outside of the hot tank sleeve 322. This keeps the power cable 81 away from the water circuit board assembly 41 where water flows, reducing the probability of water entering the power cable 81, and making the wiring path reasonable and concealed.

[0059] See Figure 5 In one specific embodiment of this application, the water treatment equipment 1 further includes a plurality of support frames 7, one end of each support frame 7 being connected to the water circuit board assembly 41, and the other end of each support frame 7 being connected to the plastic base 5. The support frame 7 is a mechanical part specifically designed for supporting, connecting, and reinforcing structures. Exemplarily, the support frame 7 can be an independent component, and its function is to provide additional mechanical connection and support between the water circuit board assembly 41 and the plastic base 5.

[0060] In the structure provided in this specific embodiment, by setting a support frame 7 directly connected to the plastic base 5, a robust beam-column structure is established between the water circuit board assembly 41 and the plastic base 5, enhancing the overall mechanical strength of the equipment. This allows the water treatment equipment 1 to better resist vibrations and impacts generated during transportation, handling, or use, preventing structural deformation. Furthermore, the water circuit board assembly 41 has numerous inlet and outlet water interfaces, and the sealing of these interfaces is crucial. By firmly fixing the water circuit board assembly 41 with the support frame 7, the risk of loose joints and leakage caused by shaking or deformation of the water circuit board assembly 41 is significantly reduced, improving the long-term reliability of the water treatment equipment 1.

[0061] Without the support frame 7, the weight and vibration load of the water circuit board assembly 41 and all the pumps, valves, water pipes and other components connected to it will be entirely borne by the insulated cover 321 and the tank 31 connection structure below it. The support frame 7 can transfer this weight and stress to the plastic base 5, effectively protecting the relatively fragile insulation components and the connection points of the tank 31, and improving the structural stability of the water treatment equipment 1.

[0062] Meanwhile, the support frame 7 can also be used as a vibration damping structure. For example, the support frame 7 itself can be designed as a flexible structure, or vibration damping pads can be used at its connection points to absorb and isolate the vibration generated by the water pump, prevent the vibration from being transmitted to the entire water treatment equipment and generate noise, and also protect other precision components inside the water treatment equipment.

[0063] like Figure 2 , Figure 6 As shown in a specific embodiment of this application, the water system 4 further includes a heat exchange component 42, which has a heating water path 421 and a circulating water path 422 that are isolated from each other. The circulating water path 422 is connected to the tank 31, and the heating water path 421 is connected to the water consumption path 411. The heat exchange component 42 is fixed to at least one of the plastic base 5, the support frame 7, and the water circuit board assembly 41. The main body 2 of the equipment also includes a thermal insulation material 82, which is wrapped around the outer periphery of the heat exchange component 42.

[0064] The heat exchange component 42 is a device for realizing heat exchange between two fluids, allowing two fluids with different temperatures to transfer heat through a material with good thermal conductivity while physically isolated. For example, the heat exchange component 42 may include a plate heat exchanger or a shell-and-tube heat exchanger. A plate heat exchanger is composed of multiple corrugated metal plates stacked together, with the cold and hot fluids flowing within adjacent plate channels for heat exchange. A shell-and-tube heat exchanger consists of one tube nested inside another, with the two fluids flowing in the inner tube and the interlayer between the inner and outer tubes, respectively.

[0065] The heating water path 421 is the channel through which the water supplied to the user in the heat exchange component 42 flows. Cold water flows in from one end of the heating water path 421, absorbs heat from the circulating water path 422, and becomes hot water, which flows out from the other end of the heating water path 421. The circulating water path 422 is filled with heat exchange medium. After flowing out of the tank 31, the heat exchange medium flows through the circulating water path 422, transferring heat to the cold water in the heating water path 421. After cooling down, it flows back to the tank 31 for reheating, and so on. The insulation material 82 is a material wrapped around the outside of the heat exchange component 42 to reduce its heat loss. The insulation material 82 can be a porous material with a low thermal conductivity, such as rubber and plastic insulation cotton, polyurethane foam, glass wool, etc. The water in the circulating water path 422 and the heating water path 421 can flow in opposite directions.

[0066] In the structure provided in this specific embodiment, heat exchange occurs through mutually isolated heating water path 421 and circulating water path 422. The heat exchange medium in the circulating water path 422 is heated within the tank 31 and then transfers heat to the drinking water flowing through the heating water path 421 at the heat exchange component 42. The medium in the circulating water path 422 can be preheated and stored in the tank 31, enabling instant heat exchange and providing immediate heating when hot water is needed. The heat exchange component 42 is fixed to at least one of the three robust structural components: the plastic base 5, the support frame 7, and the water path plate assembly 41. This ensures that the potentially heavy and bulky heat exchange component 42 is securely and reliably housed within the water treatment equipment 1, preventing loosening due to water flow impact or vibration, thus guaranteeing the airtightness of the water treatment equipment 1.

[0067] like Figure 6 As shown, the water system 4 may further include a heater 84, a water outlet 85, a wastewater discharge 86, and an exhaust passage 87. The heater 84 is connected downstream of the heating water passage 421, further heating the water heated by the heat exchange component 42. The heater 84, in conjunction with the heat exchange component 42, allows a large flow of water to be rapidly heated to the required temperature. The water outlet 85 is connected downstream of the heater 84, outputting heated hot water. The water outlet 85 can also be connected downstream of the heat exchange inlet 412, directly outputting water that does not flow into the tank 31 as ambient temperature water. The wastewater discharge 86 can be located downstream of the tank 31 and the water outlet 85, discharging excess water. The exhaust passage 87 connects to the top of the heat exchange medium cavity 311 inside the tank 31, discharging gas from the heat exchange medium cavity 311.

[0068] See Figures 1-4 In one specific embodiment of this application, the water treatment device 1 further includes a housing 6, within which a mounting cavity 61 is provided. The device body 2 and the plastic base 5 are disposed within the mounting cavity 61. The housing 6 includes a second positioning protrusion 62, and the plastic base 5 has a second positioning groove 53 on the side facing away from the hot tank assembly 3. The second positioning protrusion 62 is disposed on the side of the housing 6 facing the mounting cavity 61, and the second positioning protrusion 62 is inserted one-to-one into the second positioning groove 53, connecting the plastic base 5 and the housing 6.

[0069] The second positioning protrusion 62 and the second positioning groove 53 are similar to the first positioning protrusion 52 and the first positioning groove 324 mentioned above, and will not be described again here. The outer shell 6 is the outermost shell of the water treatment equipment 1, constituting the external shape and appearance of the water treatment equipment 1. The outer shell 6 can protect the internal components, prevent dust and water, provide heat insulation, and enhance aesthetics. The outer shell 6 can be made of plastic or metal. The mounting cavity 61 is a pre-designed cavity inside the outer shell 6 for accommodating and installing components such as the equipment body 2 and the plastic base 5, and its shape matches the contour of the equipment body 2, the plastic base 5, and other components.

[0070] In the structure provided in this specific embodiment, when the plastic base 5 and the main body 2 are installed into the "installation cavity 61" of the outer shell 6, the second positioning protrusion 62 and the second positioning groove 53 play a guiding and positioning role. The operator can easily align the second positioning protrusion 62 with the second positioning groove 53, thereby quickly placing the plastic base 5 and the main body 2 in the correct position and reducing the probability of misalignment or misplacement, which greatly improves the assembly efficiency of the water treatment equipment 1. Through the engagement of the second positioning protrusion 62 and the second positioning groove 53, the contact area between the outer shell 6 and the plastic base 5 is greatly increased, making the connection between the outer shell 6 and the plastic base 5 more secure. This allows for better stress distribution while bearing forces in various directions, reducing the probability of local deformation of the outer shell 6 and the plastic base 5, and enhancing the overall structural stability of the water treatment equipment 1.

[0071] Furthermore, the multiple second positioning protrusions 62 can be arranged in a crisscrossing manner, and the multiple second positioning grooves 53 can also be arranged in a crisscrossing manner. The crisscrossing arrangement can better withstand forces in various directions while dispersing stress, which can reduce the probability of local deformation of the outer shell 6 and the plastic base 5, and enhance the overall structural stability of the water treatment equipment 1.

[0072] like Figure 4 As shown in a specific embodiment of this application, the water treatment device 1 further includes a support foot 9, the outer shell 6 is provided with a through hole 63, the plastic base 5 is provided with a snap-fit ​​groove 54, and the support foot 9 is provided with a hook 91 on the side facing the outer shell 6. The hook 91 passes through the through hole 63 and engages with the snap-fit ​​groove 54.

[0073] The support foot 9 is installed at the bottom of the water treatment equipment 1 to support the weight of the entire equipment and maintain its balance and stability. The support foot 9 can be made of elastic materials with a high coefficient of friction, such as rubber, silicone, or plastic. The through hole 63 is a hole extending through the thickness of the outer casing 6 at its bottom, providing a passage to the internal space for the hook 91 on the support foot 9. The snap-fit ​​groove 54 is a groove or hole on the plastic base 5 specifically designed for snap-fitting. It typically has an inverted or protruding structure inside, which can interlock with the corresponding structure on the hook 91. The hook 91 is a hook-shaped structure on the support foot 9. During insertion, the hook 91 undergoes elastic deformation. Once it passes through the through hole 63 and reaches the predetermined position in the snap-fit ​​groove 54, it returns to its original shape, and its hook head hooks the inner edge of the snap-fit ​​groove 54, forming a lock.

[0074] In the structure provided in this specific embodiment, the hook 91 of the support foot 9 passes directly through the through hole 63 from the outside of the outer shell 6 and engages with the snap-fit ​​groove 54 of the internal plastic base 5. This allows the overall weight of the equipment to be transferred to the support foot 9 through the plastic base 5 and the outer shell 6, thus fixing the three together while reducing the probability of deformation of the outer shell 6 due to excessive load and ensuring the stability of the equipment. The snap-fit ​​method between the hook 91 and the snap-fit ​​groove 54 typically does not require any additional fasteners, achieving tool-free installation, thereby reducing the number of parts, simplifying the assembly process, and lowering the material and assembly costs of the water treatment equipment 1. Furthermore, the hook 91 and the snap-fit ​​groove 54 are hidden inside the outer shell 6, with only the support foot 9 visible from the outside, making the water treatment equipment 1 look neat and aesthetically pleasing.
