Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a water purifier. Background Technology

[0002] A water purifier is a water treatment device that performs deep filtration and purification of water according to usage requirements. Internally, it includes components such as a power supply unit and a water circuit board. The power supply unit can be a power storage component or a component that can connect to an external power source and convert the external power into usable electrical energy for its functional components, such as a power adapter or inverter power supply. The water circuit board typically functions as a water flow guide, pressure management unit, leak and backflow prevention unit, and interface integration unit. Examples include Chinese invention patents such as application number CN202411256687.5 (publication number CN118954650A) entitled "A Water Purification System and Water Purification Equipment," and application number CN202410374061.8 (publication number CN118021145A) entitled "A Hot and Cold Integrated Water Purifier."

[0003] Traditional water purifiers often feature a cross-connection of water and electrical circuits, resulting in a chaotic internal wiring layout and compromising stability and safety. For example, a water leak could damage the electrical circuitry. Furthermore, various connectors on the water circuit board (e.g., inlet, outlet, and water dispenser connectors) require separate installation in different locations, leading to a complex and space-consuming internal wiring layout. Additionally, the power adapter's secure mounting relies on a fragmented installation structure, such as direct screw fixation to the frame or outer shell, which can be insecure and prone to loosening. Summary of the Invention

[0004] The first technical problem to be solved by this utility model is to provide a water purifier that has independent water and electrical circuits, good safety in use, and strong functional stability, in contrast to the existing technology.

[0005] The second technical problem to be solved by this utility model is to provide a water purifier with a simple internal circuit layout, which is different from the prior art.

[0006] The third technical problem to be solved by this utility model is to provide a water purifier with a robust internal installation structure, which is in contrast to the prior art.

[0007] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is as follows: a water purifier, including a housing and a power supply component and a water circuit board installed in the housing, characterized in that a mounting bracket is provided vertically in the housing, the mounting bracket is fixed to the housing and includes a first mounting area and a second mounting area located below the first mounting area along its own height direction, wherein the first mounting area is used to install the power supply component and the power circuit board's power-conducting connector, and the second mounting area is used to install the water circuit board's water-conducting connector.

[0008] Furthermore, the housing is provided with a horizontally extending mounting platform, on the top surface of which a first mounting seat protrudes, and the top of the aforementioned mounting bracket is provided with a second mounting seat.

[0009] The aforementioned power supply assembly includes a power adapter mounted flat on the mounting platform. A first end of the power adapter is fixed to a first mounting base via a first fastener, and a second end is fixed to a second mounting base via a second fastener. The power supply assembly can be implemented in various ways; in this invention, it includes a power adapter, and the mounting platform, the first mounting base on the platform, and the second mounting base on the mounting bracket enable a stable installation of the power adapter within the housing.

[0010] Furthermore, the power adapter is square in shape. A vertically extending first limiting member protrudes from the outer surface of the first mounting base. The top of the mounting bracket is provided with vertically extending second and third limiting members. The second limiting member is opposite to the first limiting member; the first limiting member abuts against the first end of the power adapter, while the second limiting member abuts against the second end. The third limiting member is opposite to one side panel of the housing, and both abut against the two sides of the power adapter, respectively. By using the first, second, and third limiting members and the corresponding side panels of the housing to limit the power adapter's position, not only is it convenient to fix the power adapter (using pre-positioning followed by fastener fixation), but it also helps to improve the stability and reliability of the power adapter installation.

[0011] Furthermore, both the second and third limiting members are vertical plates, perpendicular to each other and connected at their corresponding ends. The second limiting member has a recessed first notch for the power connector on the second end of the power adapter to pass through, and the top of the mounting bracket has a first groove for the power cord of the power adapter to pass through. The first notch is located on one side wall of the first groove, while a second notch is located on the other side wall of the first groove for the power cord to exit the mounting bracket. This allows the second and third limiting members to better limit the power adapter, while the first groove and the first and second notches on it facilitate the routing of the power cord.

[0012] Furthermore, one side of the mounting bracket extends horizontally outward to form a support platform. The second end of the power adapter extends out of the mounting platform and rests on the top surface of the support platform. A third mounting seat is provided on the free end of the support platform. The water circuit board is vertically disposed on one side of the mounting bracket and fixed to the third mounting seat by a third fastener. The support platform helps to ensure the stable installation of the power adapter. Furthermore, fixing the mounting bracket to the water circuit board via the support platform not only facilitates the stable installation of the mounting bracket but also ensures reliable connection between the connectors on the mounting bracket and their corresponding points on the water circuit board.

[0013] Furthermore, the first installation area has a mounting groove at the top of the mounting bracket for mounting the adapter plate, and a wiring window for the adapter plate's connecting wires to pass through is provided on one side of the bottom wall of the mounting groove. The adapter plate can expand the control functions of the water purifier's main control board, and the mounting groove facilitates the installation and wiring of the adapter plate in the housing.

[0014] Furthermore, the mounting bracket includes a vertically extending first vertical plate, which is attached to the first side plate of the housing. The aforementioned power-conducting connector is located in the middle of the first vertical plate in the first mounting area, while the aforementioned water-conducting connector is located at the lower end of the first vertical plate in the second mounting area. This centralized mounting of the connectors on the first vertical plate of the mounting bracket allows for a more compact and streamlined internal layout of the housing. It also facilitates the exposure of the ends of each connector on the outer surface of the housing (through holes in the first side plate). Furthermore, positioning the power-conducting connector in the middle of the first vertical plate and placing the water-conducting connector at the lower end allows for better separation of wet and dry water and electrical circuits.

[0015] Furthermore, in the first installation area, a first mounting hole, a second mounting hole, and a third mounting hole are respectively provided in the middle part of the first vertical plate for the power cord to pass through. The aforementioned power-conducting connectors include a water inlet solenoid valve connector and a water dispenser connector. The water inlet solenoid valve connector passes through the second mounting hole, and the water dispenser connector passes through the third mounting hole. The first mounting hole allows the power cord to pass through the housing; the second mounting hole allows the water inlet solenoid valve connector to be installed on the mounting bracket; and the third mounting hole allows the water dispenser connector to be installed on the mounting bracket.

[0016] Furthermore, a fourth mounting hole and a fifth mounting hole are respectively provided on the lower side of the first vertical plate. The aforementioned water-conducting connector includes a water inlet connector and a water outlet connector. The water inlet connector passes through the fourth mounting hole, while the water outlet connector passes through the fifth mounting hole. The fourth mounting hole enables the water inlet connector to be installed on the mounting bracket, and the fifth mounting hole enables the water outlet connector to be installed on the mounting bracket.

[0017] Furthermore, the mounting bracket is a single piece, including a vertically extending first vertical plate. One side surface of the first vertical plate is abutted against a vertically extending first side plate of the housing. A horizontally extending boss is protruding from one end of the first vertical plate on its other side surface. The outer side wall of the boss extends vertically and abuts against a vertically extending second side plate of the housing. The first and second side plates of the housing are connected and perpendicular to each other. Assembly holes are respectively formed on the other end of the first vertical plate and on the outer side wall of the boss. Each assembly hole is fixed to the corresponding side plate of the housing by assembly fasteners. This ensures the internal structure of the mounting bracket (single-piece design) is robust and allows the mounting bracket to be securely installed in the housing, preventing it from loosening due to vibration or load.

[0018] Compared with existing technologies, the advantages of this utility model are as follows: the mounting bracket includes a first mounting area and a second mounting area located below the first mounting area along its height. The first mounting area is used to install the power supply components and the power-conducting connector of the water circuit board, while the second mounting area is used to install the water-conducting connector of the water circuit board. Therefore, by setting the first and second mounting areas, the water circuit and electrical circuit are installed in a dry and wet separation manner on the mounting bracket, avoiding safety issues caused by the cross-installation of water circuits and electrical circuits, and helping to ensure the safety and functional stability of the water purifier. Furthermore, concentrating the power-conducting and water-conducting connectors of the water circuit board on the mounting bracket simplifies the internal layout of the water purifier and makes full use of the internal installation space.

[0029] like Figures 1-8 As shown, a water purifier includes a housing 1 and a power supply component and a water circuit board 2 installed in the housing 1. Further, a mounting bracket 3 is vertically arranged in the housing 1. The mounting bracket 3 is fixed to the housing 1 and includes a first mounting area 3a and a second mounting area 3b located below the first mounting area 3a along its height direction. The first mounting area 3a is used to install the power supply component and the power supply connector of the water circuit board 2, and the second mounting area 3b is used to install the water supply connector of the water circuit board 2.

[0030] In this invention, the mounting bracket 3 includes a first mounting area 3a and a second mounting area 3b located below the first mounting area 3a along its height. The first mounting area 3a is used to install the aforementioned power supply components and the power-conducting connectors of the water circuit board 2, while the second mounting area 3b is used to install the water-conducting connectors of the water circuit board 2. It is evident that by setting the first mounting area 3a and the second mounting area 3b, the water circuit and electrical circuit are installed in separate wet and dry areas on the mounting bracket 3, avoiding safety issues caused by the cross-installation of water circuits and electrical circuits, and thus ensuring the safety and functional stability of the water purifier. Furthermore, concentrating the power-conducting and water-conducting connectors of the water circuit board 2 on the mounting bracket 3 simplifies the internal layout of the water purifier and makes full use of the internal installation space.

[0031] like Figure 1 As shown, the housing 1 has a horizontally extending mounting platform 4. A first mounting seat 41 protrudes from the top surface of the mounting platform 4, and a second mounting seat 321 is provided on the top of the mounting bracket 3. Specifically, in this embodiment, the power supply component includes a power adapter 5 placed flat on the mounting platform 4. The first end of the power adapter 5 is fixed to the first mounting seat 41 by a first fastener 61, and the second end is fixed to the second mounting seat 321 by a second fastener 62. The power supply component can have various specific implementations. In this invention, the power supply component includes a power adapter 5, and the mounting platform 4, the first mounting seat 41 on the mounting platform 4, and the second mounting seat 321 on the mounting bracket 3 enable the power adapter 5 to be stably installed in the housing 1. In this embodiment, both the first mounting seat 41 and the second mounting seat 321 are vertically extending columns, each with through holes along its height for corresponding fasteners to pass through. Both the first fastener 61 and the second fastener 62 are screws.

[0032] Furthermore, such as Figure 1 and Figure 4 As shown, the power adapter 5 is square in shape. A vertically extending first limiting member 42 protrudes from the outer surface of the first mounting base 41, while the top of the mounting bracket 3 is provided with vertically extending second limiting members 322 and third limiting members 323. The second limiting member 322 is opposite to the first limiting member 42. The first limiting member 42 abuts against the first end of the power adapter 5, while the second limiting member 322 abuts against the second end of the power adapter 5. The third limiting member 323 is opposite to one side plate of the housing 1 (in this embodiment, the second side plate 12), and both abut against the two sides of the power adapter 5. By using the first limiting member 42, the second limiting member 322, the third limiting member 323, and the corresponding side plate of the housing 1 to limit the movement of the power adapter 5, it not only facilitates the fixed installation of the power adapter 5 (using pre-positioning followed by fastener fixing) but also improves the stability and reliability of the power adapter 5 installation.

[0033] Specifically, such as Figure 4As shown, both the second limiting member 322 and the third limiting member 323 are vertical plates, perpendicular to each other and connected at their corresponding ends. Furthermore, the second limiting member 322 has a recessed first notch 3241 for the power connector 51 on the second end of the power adapter 5 to pass through, and the top of the mounting bracket 3 has a first groove 324 for the power cord of the power adapter 5 to pass through. The first notch 3241 is located on one side wall of the first groove 324, while a second notch 3242 for the power cord to exit the mounting bracket 3 is located on the other side wall of the first groove 324. This allows the second limiting member 322 and the third limiting member 323 to better limit the power adapter 5, while the first groove 324 and the first and second notches 3241 on the first groove 324 enable the routing of the power cord.

[0034] Preferably, such as Figure 4 As shown, one side of the mounting bracket 3 extends horizontally outward to form a support platform 325. The second end of the power adapter 5 extends out of the mounting platform 4 and rests on the top surface of the support platform 325. A third mounting seat 326 is provided on the free end of the support platform 325. The water circuit board 2 is vertically arranged on one side of the mounting bracket 3 and fixed to the third mounting seat 326 by a third fastener 63. The support platform 325 helps to ensure the stable installation of the power adapter 5. Fixing the mounting bracket 3 to the water circuit board 2 via the support platform 325 not only facilitates the stable installation of the mounting bracket 3 but also ensures reliable connection between the connectors on the mounting bracket 3 and the corresponding points on the water circuit board 2. The third fastener 63 is also a screw.

[0035] like Figure 4 and Figure 8 As shown, in the first installation area 3a, a mounting groove 327 for mounting an adapter plate is provided on the top of the mounting bracket 3, and a wiring window 328 for the connecting wires of the adapter plate 7 to pass through is provided on one side of the bottom wall of the mounting groove 327. The adapter plate 7 can expand the control function of the main control board of the water purifier, and the mounting groove 327 facilitates the installation and wiring of the adapter plate 7 in the housing 1.

[0036] like Figure 5 As shown, the mounting bracket 3 includes a vertically extending first vertical plate 31, which is attached to the first side plate 11 of the housing 1. A power connector is provided in the middle of the first vertical plate 31 in the first mounting area 3a, and a water connector is provided at the lower end of the first vertical plate 31 in the second mounting area 3b. This centralized mounting of the connectors on the first vertical plate 31 of the mounting bracket 3 makes the internal layout of the housing 1 more compact and simple, while also allowing the ends of the connectors to be exposed on the outer surface of the housing 1 (through holes opened in the first side plate 11, such as...). Figure 2As shown), the power-conducting connector is placed in the middle of the first vertical plate 31, while the lower end of the water-conducting connector can better realize the dry and wet partitioning of water and electrical circuits.

[0037] Specifically, such as Figure 7 As shown, in the first mounting area 3a, a first mounting hole 311, a second mounting hole 312, and a third mounting hole 313 are respectively provided in the middle part of the first vertical plate 31 for the power cord to pass through. The power-conducting connectors include a water inlet solenoid valve connector 21 and a water dispenser connector 22. The water inlet solenoid valve connector 21 passes through the second mounting hole 312, and the water dispenser connector 22 passes through the third mounting hole 313. The first mounting hole 311 allows the power cord to pass through the inside of the housing 1 (through a hole in the first side plate 11), the second mounting hole 312 allows the water inlet solenoid valve connector 21 to be installed on the mounting bracket 3, and the third mounting hole 313 allows the water dispenser connector 22 to be installed on the mounting bracket 3. Meanwhile, a fourth mounting hole 314 and a fifth mounting hole 315 are respectively provided on the lower side of the first vertical plate 31. The water-conducting connector includes a water inlet connector 23 and a water outlet connector 24. The water inlet connector 23 passes through the fourth mounting hole 314, while the water outlet connector 24 passes through the fifth mounting hole 315. The fourth mounting hole 314 enables the water inlet connector 23 to be installed on the mounting bracket 3, and the fifth mounting hole 315 enables the water outlet connector 24 to be installed on the mounting bracket 3.

[0038] like Figure 6 and Figure 7 As shown, in this embodiment, the first mounting hole 311 includes a semi-circular hole body 3111 and a square extension window 3112 located on the hole body 3111. It also includes a mounting block 8, the bottom of which is recessed with a semi-circular mounting groove 81. The mounting block 8 is fixed to the mounting bracket 3, and one end of the mounting block 8 is embedded in the extension window 3112. Simultaneously, the mounting groove 81 on the mounting block 8 and the hole body 3111 are joined vertically to form a circular power cord hole 9 for power cord insertion. The formed power cord hole 9 limits the movement of the power cord, ensuring the reliability of the power cord routing path.

[0039] like Figure 7 and Figure 8As shown in this embodiment, the mounting bracket 3 is a single piece. One side surface of the first vertical plate 31 is fitted with the vertically extending first side plate 11 of the housing 1. A horizontally extending boss 32 protrudes from one end of the first vertical plate 31 onto its other side surface. The outer side wall of the boss 32 extends vertically and fits against the vertically extending second side plate 12 of the housing 1. Furthermore, the first side plate 11 and the second side plate 12 of the housing 1 are connected and perpendicular to each other. Assembly holes 33 are respectively provided on the other end of the first vertical plate 31 and on the outer side wall of the boss 32. Each assembly hole 33 is fixed to the corresponding side plate of the housing 1 by an assembly fastener 64 (also a screw). This ensures the internal structure (single-piece design) of the mounting bracket 3 is robust and allows the mounting bracket 3 to be securely installed in the housing 1, preventing the mounting bracket 3 from loosening due to vibration or load. In this embodiment, the second mounting base 321, the first groove 324, the support platform 325, and the mounting groove 327 are all disposed on the boss 32. Furthermore, the first mounting area 3a includes the upper end of the first vertical plate 31 and the boss 32, while the second mounting area 3b includes the lower end of the first vertical plate 31, as shown below. Figure 7 As shown ( Figure 7 The dashed line in the diagram represents the demarcation between the two.
