Description

Technical Field

[0001] This application relates to the field of water purification equipment technology, specifically to a faucet water purifier that integrates purification and heating. Background Technology

[0002] With economic development and improved living standards, consumers are paying increasing attention to healthy drinking water and have higher requirements for its use. Water purifiers, as water treatment devices that can deeply filter and purify water according to usage requirements, are essential. There are many types of water purifiers, such as central water purifiers, pre-filters, RO machines, water softeners, and faucet water purifiers. Among them, faucet water purifiers, which are fixed to the faucet and directly filter impurities and chlorine from the water as it flows out, are gaining increasing recognition and favor from consumers due to their small size and ease of use.

[0003] Currently, most faucet water purifiers only have a single water purification function, which cannot meet people's growing and changing water needs, especially the demand for hot water. Although some faucet water purifiers with heating functions have appeared on the market, which mainly include a filtration unit and a heating unit, and can meet the basic needs of filtration and heating, when the filtration unit and heating unit are integrated into the faucet water purifier, the arrangement of the various components of the faucet water purifier within the limited space is subject to the limitations of space structure and installation process requirements.

[0004] Moreover, it has been proven that the arrangement of the various components of a faucet water purifier has a significant impact on its size, efficiency of disassembly and assembly, service life, and reliability. However, the existing integrated water purifiers with both purification and heating functions have a wide variety of arrangements and many defects. In the existing technology, due to the unreasonable internal structure arrangement, there are defects such as large size, which leads to a large space occupation during installation, complex water flow path leading to slow water output, non-compact structure, and inconvenient disassembly and maintenance. These defects bring great trouble to the production, manufacturing, installation, and reliable use of integrated water purifiers with both purification and heating functions. Summary of the Invention

[0005] This application provides an integrated water purifier and heater faucet to solve at least one of the aforementioned technical problems. The technical solution adopted in this application is as follows:

[0006] A water purifier with integrated purification and heating functions includes a water path switching unit, a filtration unit, and a heating unit. The water path switching unit has a raw water inlet and a raw water outlet. The filtration unit has a raw water inlet and a purified water outlet, with the raw water inlet communicating with the raw water inlet. The filtration unit includes a filter element and a housing for accommodating the filter element. The heating unit is disposed within the housing and has a purified water chamber accommodating the filter element and a heating chamber surrounding the purified water chamber. The purified water chamber has an inlet located on the water inlet side of the filter element and an outlet located on the water outlet side of the filter element. The raw water inlet communicates with the inlet, and the outlet and purified water outlet are respectively communicated with the heating chamber. The outlet and inlet are located on the upper and lower sides of the purified water chamber, respectively. A control unit is located above the outlet. Purified water, after being filtered by the filter element, flows out of the outlet and triggers the control unit before entering the heating chamber.

[0007] The integrated water purifier and heater faucet water purifier in this application also has the following additional technical features:

[0008] The heating unit includes a heating cylinder, a shell housing the heating cylinder, and an upper support and a lower support respectively disposed at both ends of the shell. The heating cylinder includes an inner wall and an outer wall of a double-layer structure. The inner wall, the upper support, and the lower support together form the purified water chamber. The inner wall and the outer wall of the double-layer structure form the heating chamber. The water outlet is disposed on the upper support, and the water inlet is disposed on the lower support. Multiple heating inlets communicating with the heating chamber and the water outlet are disposed at intervals along the circumference on the upper part of the inner wall of the double-layer structure. Multiple hot water outlets communicating with the heating chamber and the purified water outlet are disposed at intervals along the circumference on the lower part of the inner wall of the double-layer structure.

[0009] The filtration unit further includes an upper end cap fixed to the water outlet side of the filter element, the upper end cap having a water outlet port; the upper end cap having a first guide protrusion communicating with the water outlet port and extending toward the water outlet, the upper support having a second guide protrusion communicating with the water outlet port and extending toward the water outlet port, the second guide protrusion sealingly engaging with the first guide protrusion and restricting the movement of the filter element toward the lower support.

[0010] The upper support includes a first mounting part, a second mounting part located below the first mounting part, and a connecting part connecting the first mounting part and the second mounting part. The outer periphery of the first mounting part is sealed to the outer wall of the interlayer, and the outer periphery of the second mounting part is sealed to the inner wall of the interlayer. The water outlet and the second flow guide protrusion are disposed on the second mounting part. The connecting part forms a first flow guide channel that communicates with the water outlet and the heating inlet respectively.

[0011] The bottom of the second mounting part is recessed upward to form a cavity, the water outlet is located in the cavity, and at least part of the upper end cap extends into the cavity and is interference-fitted into the cavity.

[0012] The filter element is removably disposed in the water purification chamber through the water inlet. The bottom of the housing is provided with an opening facing the water inlet. The filter unit also includes a lower cover plate for opening or closing the opening. The filter element can be pushed into the water purification chamber through the opening or taken out of the housing through the opening.

[0013] The filtration unit also includes a lower end cover fixed to the lower side of the filter element, and the lower end cover is provided with an operating handle facing the water inlet.

[0014] The control unit includes a control switch and a circuit board disposed inside the housing and electrically connected to the heating unit. The control switch includes a trigger part and a sensing part. The trigger part can trigger the sensing part or de-trigger the sensing part according to the water flow in the water purification chamber.

[0015] In the structure of the upper bracket including a first mounting part, a second mounting part located below the first mounting part, and a connecting part connecting the first mounting part and the second mounting part, the top of the first mounting part is recessed downward to form a mounting groove for mounting the control switch, and the first mounting part is provided with a second guide channel that communicates with the first guide channel and extends toward the trigger part.

[0016] The filtration unit also includes a water circuit board located inside the housing and detachably disposed below the water purification chamber. The water circuit board integrates the raw water inlet, the purified water outlet, a raw water inlet channel that connects the raw water inlet and the water inlet respectively, and a purified water outlet channel that connects the heating chamber and the purified water outlet respectively. The raw water inlet extends out from the housing to communicate with the raw water inlet, and the purified water outlet communicates with the outside.

[0017] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows:

[0018] 1. The integrated water purifier and heating faucet provided in this application first integrates a filtration unit and a heating unit to realize the water output process of filtering first and then heating, thereby meeting the user's needs for purified and warm water washing.

[0019] Secondly, compared to the existing technical solutions where the heating unit and the filter unit are installed independently in two separate housings, this application integrates the filter element and the heating unit into one housing, and installs the filter element in the water purification chamber formed by the heating unit, forming a structure in which the housing is fitted with the heating unit and the heating unit is fitted with the filter element. This makes full use of the space inside the housing and the heating unit, which helps to greatly reduce the size and space occupied by the water purifier, realize the miniaturization of the faucet water purifier, leave a larger water receiving space below the faucet water purifier, and also facilitate the transportation and installation of the faucet water purifier product.

[0020] In addition, this application places the outlet and inlet on the upper and lower sides of the water purification chamber, respectively, forming a water flow path where raw water enters from the lower side and purified water exits from the upper side. The purified water flowing out from the upper side enters the heating chamber and is heated while flowing downwards, thereby achieving a single cycle of raw water rising and hot water falling to discharge, shortening the water flow path and facilitating rapid drainage.

[0021] 2. As a preferred embodiment of this application, by providing heating inlets that communicate with the water outlet at intervals along the circumference on the upper part of the inner wall of the interlayer, and providing hot water outlets that communicate with the purified water outlet at intervals along the circumference on the lower part of the inner wall of the interlayer, the pressure of unheated purified water entering the heating chamber can be relieved by multiple heating inlets when the water pressure is high, and the pressure of purified water splashing after heating can be reduced by multiple hot water outlets, so that hot water flows out of the heating chamber in a relatively gentle manner, and hot water flows out of the water purifier quickly, smoothly and evenly.

[0022] 3. In a preferred embodiment of this application, the upper end cover is provided with a first guide protrusion that connects to the water outlet port and extends toward the water outlet, and the upper bracket is provided with a second guide protrusion that connects to the water outlet port and extends toward the water outlet port. Through the sealing cooperation between the first guide protrusion and the second guide protrusion, not only is the sealing of the water outlet port and the water outlet port connected together achieved, preventing the backflow of purified water, but also the radial and axial limiting of the filter element by the upper bracket is achieved, improving the installation stability of the filter element and ensuring the normal operation of raw water filtration.

[0023] 4. In a preferred embodiment of this application, the bottom of the second mounting part is recessed upward to form a cavity, the water outlet is located in the cavity, and at least part of the upper end cap extends into the cavity and is interference-fitted with the cavity, so that the clamping effect of the cavity on the upper end cap, together with the second guide protrusion, can achieve radial and axial positioning of the filter element, further improving the installation stability of the filter element and preventing the filter element from falling off the upper support, which would cause the raw water to enter the heating chamber directly without being filtered. In addition, the squeezing effect of the upper end cap on the inner wall of the cavity can further improve the sealing performance at the joint between the upper support and the inner wall of the interlayer.

[0024] 5. As a preferred embodiment of this application, by making the filter element removably placed in the water purification chamber through the water inlet, and the outer shell having an opening facing the water inlet, the filter unit also includes a lower cover plate for opening or closing the opening. The filter element can be pushed into the water purification chamber through the opening or taken out from the outer shell through the opening, which facilitates the replacement of the filter element, which is the main consumable, without having to scrap the entire integrated water purifier and heat faucet water purifier, thus reducing the cost of filter replacement.

[0025] Furthermore, the filter unit also includes a lower end cover fixed to the lower side of the filter element. The lower end cover is provided with an operating handle facing the water inlet. The operating handle facilitates the connection between the first guide protrusion and the second guide protrusion during filter element installation, and also facilitates the removal of the filter element from the upper bracket during filter element replacement.

[0052] like Figures 1 to 14The illustrated water purifier with integrated water purification and heating includes a water circuit switching unit 1, a filtration unit 2, and a heating unit 3. The water circuit switching unit 1 has a raw water inlet 11 and a raw water outlet 12. The filtration unit 2 has a raw water inlet 251 and a purified water outlet 252, with the raw water inlet 251 communicating with the raw water inlet 11. The filtration unit 2 includes a filter element 21 and a housing 22 for housing the filter element 21. The heating unit 3 is disposed within the housing 22 and has a housing for... The filter element 21 has a water purification chamber 35 and a heating chamber 36 surrounding the outside of the water purification chamber 35. The water purification chamber 35 has an inlet 341 located on the water inlet side of the filter element 21 and an outlet 3321 located on the water outlet side of the filter element 21. The raw water inlet 251 is connected to the inlet 341. The outlet 3321 and the purified water outlet 252 are respectively connected to the heating chamber 36. The outlet 3321 and the inlet 341 are respectively located on the upper and lower sides of the water purification chamber 35.

[0053] In the integrated water purifier and heat faucet provided in this application, such as Figure 1 , Figure 2 and Figure 3 As shown, firstly, the filter unit 2 and the heating unit 3 are integrated to realize the water output process of filtering first and then heating, which meets the user's needs for purified and warm washing, and is especially suitable for occasions with high demand for warm and hot water.

[0054] Secondly, compared with the existing technical solution where the heating unit 3 and the filter unit 2 are independently installed in two housings 32, this application integrates the filter element 21 and the heating unit 3 into one housing 22, and installs the filter element 21 in the water purification chamber 35 formed by the heating unit 3, forming a structure in which the housing 22 is fitted with the heating unit 3 and the heating unit 3 is fitted with the filter element 21. This makes full use of the space inside the housing 22 and the heating unit 3, which helps to greatly reduce the size and space occupied by the water purifier, realize the miniaturization of the faucet water purifier, leave a larger water receiving space below the faucet water purifier, and also facilitate the transportation and installation of the faucet water purifier product.

[0055] In addition, this application places the outlet 3321 and the inlet 341 on the upper and lower sides of the water purification chamber 35, respectively. When installing the filter element 21, especially when installing the filter element 21 from bottom to top, it facilitates the connection between the outlet side of the filter element 21 and the outlet 3321. Moreover, it forms a water flow path where raw water enters from the lower side and purified water exits from the upper side. The purified water flowing out from the upper side enters the heating chamber 36 and flows downward while being heated, thereby realizing that the raw water rises and the hot water falls in a single cycle to discharge, shortening the water flow path and helping to drain quickly.

[0056] Specifically, the water circuit switching unit 1 described in this application is used to connect with a faucet, which meets the needs of directly discharging raw water and supplying raw water to the filter unit 2. The switching between discharging raw water and hot water can be achieved by operating the handle 13. When discharging hot water, the raw water inlet 251 is connected to the raw water inlet 11. The raw water flowing from the faucet enters the purified water chamber 35 through the raw water inlet 251 and the inlet 341 in sequence. In the purified water chamber 35, it is filtered by the filter element 21 into room temperature purified water, which flows out from the outlet 3321 and enters the heating chamber 36 to be heated into hot water at a higher temperature and discharged through the purified water outlet 252. When discharging raw water, the water circuit switching unit 1 cuts off the connection between the raw water inlet 251 and the raw water inlet 11. The raw water flowing from the faucet is directly discharged through the raw water outlet 12 of the water circuit switching unit 1.

[0057] It should be noted that this application does not specifically limit the structure of the filter element 21. It can be as follows: Figure 7 The filter element 21 shown is wound into a cylindrical structure, or it can be a filter element with a planar layered structure.

[0058] As a preferred embodiment of this application, such as Figure 1 , Figure 3 and Figure 15 As shown, the heating unit 3 includes a heating cylinder 31, a shell 32 housing the heating cylinder 31, and an upper support 33 and a lower support 34 respectively disposed at both ends of the shell 32. The heating cylinder 31 includes an inner wall 311 and an outer wall 312. The inner wall 311, the upper support 33, and the lower support 34 together form the water purification chamber 35. The inner wall 311 and the outer wall 312 together form the heating chamber 36. Figure 3 , Figure 4 and Figure 14 As shown, the water outlet 3321 is disposed on the upper support 33, the water inlet 341 is disposed on the lower support 34, a plurality of heating inlets 3111 connecting the heating chamber 36 and the water outlet 3321 are disposed at intervals along the circumference on the upper part of the inner wall 311 of the interlayer, and a plurality of hot water outlets 3112 connecting the heating chamber 36 and the purified water outlet 252 are disposed at intervals along the circumference on the lower part of the inner wall 311 of the interlayer.

[0059] By providing multiple heating inlets 3111 at intervals along the circumference on the upper part of the inner wall 311 of the interlayer, and multiple hot water outlets 3112 at intervals along the circumference on the lower part of the inner wall 311 of the interlayer, the pressure of unheated purified water entering the heating chamber 36 can be relieved by the multiple heating inlets 3111 when the water pressure is high, and the pressure of the heated purified water splashing can be reduced by the multiple hot water outlets 3112, so that hot water flows out of the water purifier quickly, smoothly and evenly.

[0060] In practical implementation, the housing 32 can be connected to the upper bracket 33, and the entire heating unit 3 can be connected to the bottom of the outer shell 22 through the upper bracket 33 to fix the heating unit 3 inside the outer shell 22. The upper bracket 33 serves not only to fix the heating unit 3 to the outer shell 22, but also to form part of the water purification chamber 35 and to guide the purified water filtered by the filter element 21 into the heating chamber 36, thus achieving multiple functions in one piece. In addition, sealing rings can be sandwiched between the upper bracket 33, the lower bracket 34 and the outer wall 312 of the interlayer, as well as between the inner wall 311 and the outer wall 312 of the interlayer, to improve the sealing of the water purification chamber 35 and the heating chamber 36 and prevent water leakage.

[0061] Furthermore, such as Figure 3 , Figure 4 and Figure 7 As shown, the filter unit 2 further includes an upper end cover 23 fixed to the water outlet side of the filter element 21. The upper end cover 23 is provided with a water outlet port 231. The upper end cover 23 is provided with a first guide protrusion 232 that communicates with the water outlet port 231 and extends toward the water outlet 3321. The upper support 33 is provided with a second guide protrusion 3322 that communicates with the water outlet 3321 and extends toward the water outlet port 231. The second guide protrusion 3322 is sealed and cooperates with the first guide protrusion 232 to restrict the movement of the filter element 21 toward the lower support 34.

[0062] This application selectively employs a filter element 21 wound into a cylindrical structure for easy installation. Raw water entering the water purification chamber 35 enters the hollow outlet side of the filter element 21 from the inlet side outside the filter element 21, and then flows towards the outlet 3321 of the water purification chamber 35. The upper end cover 23 is provided with a first guide protrusion 232 that connects to the outlet port 231 and extends towards the outlet 3321. The upper bracket 33 is provided with a second guide protrusion 3322 that connects to the outlet 3321 and extends towards the outlet port 231. Through the sealing cooperation between the first guide protrusion 232 and the second guide protrusion 3322, not only is the sealing of the outlet port 231 and the outlet 3321 achieved, preventing the backflow of purified water, but the upper bracket 33 also provides radial and axial limiting for the filter element 21, improving the installation stability of the filter element 21 and ensuring normal raw water filtration.

[0063] It should be noted that the cooperation between the first guide protrusion 232 and the second guide protrusion 3322 is not limited to... Figure 3 The structure shown depicts the first guide protrusion 232 extending into the second guide protrusion 3322. Alternatively, the second guide protrusion can extend into the first guide protrusion. In specific implementations, a sealing ring can be sandwiched between the first guide protrusion 232 and the second guide protrusion 3322 to improve the sealing performance of their insertion fit.

[0064] Furthermore, such as Figure 3 and Figure 6 As shown, the upper bracket 33 includes a first mounting part 331, a second mounting part 332 located below the first mounting part 331, and a connecting part 333 connecting the first mounting part 331 and the second mounting part 332. The outer periphery of the first mounting part 331 is sealed to the outer wall 312 of the interlayer, and the outer periphery of the second mounting part 332 is sealed to the inner wall 311 of the interlayer. The water outlet 3321 and the second flow guide protrusion 3322 are disposed on the second mounting part 332. The connecting part 333 forms a first flow guide channel 3331 that communicates with the water outlet 3321 and the heating inlet 3111 respectively.

[0065] The first mounting part 331 and the outer wall 312 of the interlayer are sealed together to ensure the sealing of the heating chamber 36. The second mounting part 332 and the inner wall 311 of the interlayer are sealed together to ensure the sealing of the water purification chamber 35. The first guide channel 3331 realizes the connection between the water outlet 3321 and the heating inlet 3111 and the heating chamber 36, which not only facilitates the installation, but also facilitates the rapid entry of the filtered water into the heating chamber 36 for heating.

[0066] Furthermore, such as Figure 3 and Figure 4 As shown, the bottom of the second mounting part 332 is recessed upward to form a cavity 3323, the water outlet 3321 is located in the cavity 3323, and at least part of the upper end cap 23 extends into the cavity 3323 and is interference-fitted into the cavity 3323.

[0067] The interference fit between the upper end cap 23 and the cavity 3323 allows the cavity 3323 to tighten the upper end cap 23 together with the second guide protrusion 3322 to radially and axially limit the filter element 21, further improving the installation stability of the filter element 21 and preventing the filter element 21 from falling off the upper bracket 33, which would cause the raw water to enter the heating chamber 36 directly without being filtered. In addition, the squeezing action of the upper end cap 23 on the inner wall of the cavity 3323 can further improve the sealing performance at the joint between the upper bracket 33 and the inner wall 311 of the interlayer.

[0068] As a preferred embodiment of this application, such as Figure 1 As shown, all the aforementioned embodiments of this application can further enable the filter element 21 to be removably disposed in the water purification chamber 35 through the water inlet 341, the bottom of the outer shell 22 is provided with an opening facing the water inlet 341, the filter unit 2 further includes a lower cover plate 26 for opening or closing the opening, and the filter element 21 can be pushed into the water purification chamber 35 through the opening or taken out from the outer shell 22 through the opening.

[0069] By allowing the filter element 21 to be removably placed in the water purification chamber 35 through the water inlet 341, and the outer casing 22 having an opening facing the water inlet 341, the filter unit 2 also includes a lower cover plate 26 for opening or closing the opening. The filter element 21 can be pushed into the water purification chamber 35 through the opening or taken out from the outer casing 22 through the opening, which facilitates the replacement of the filter element 21, which is the main consumable material, without having to scrap the entire integrated water purifier and heat faucet, thus reducing the cost of filter replacement.

[0070] It should be noted that this application does not specifically limit the connection method between the lower cover plate 26 and the outer shell 22. It can employ detachable connection methods such as snap-fit, screw-fit, or limiting fit, for example... Figure 10 and Figure 12 As shown, a swivel groove 261 is provided on the lower cover plate 26, and a swivel rib 221 is provided on the outer shell 22. In this application, the lower cover plate 26 and the outer shell 22 are detachably connected by the swivel groove 261 and the swivel rib 221 engaging and snapping together.

[0071] Furthermore, such as Figure 7 As shown, the filter unit 2 also includes a lower end cover 24 fixed to the lower side of the filter element 21, and the lower end cover 24 is provided with an operating handle 241 facing the water inlet 341.

[0072] The lower end cap 24 facilitates sealing of the lower part of the hollow outlet side of the filter element 21, and the operating handle 241 facilitates the installation of the filter element 21. In particular, for the technical solution of installing the filter element 21 by cooperating with the upper bracket 33 through the upper end cap 23, the operating handle 241 facilitates the docking of the first guide protrusion 232 and the second guide protrusion 3322 during the installation of the filter element 21, and also facilitates the removal of the filter element 21 from the upper bracket 33 during the replacement operation.

[0073] As a preferred embodiment of this application, such as Figure 1 , Figure 3 and Figure 13 As shown, all the aforementioned embodiments of this application can further include a control switch 4 disposed in the outer casing 22 and electrically connected to the heating unit 3. The control switch 4 includes a trigger part 41 and a sensing part 42. The trigger part 41 can trigger the sensing part 42 or de-trigger the sensing part 42 according to the water flow in the water purification chamber 35.

[0074] The control switch 4 is opened and closed by utilizing the flow of water, thereby achieving automatic heating control. This integrated water purifier and heater faucet is more automated and user-friendly, providing hot water as needed and stopping when you leave. Specifically, the trigger unit 41 can determine whether there is water flow in the purification chamber 35. When there is water flow, the trigger unit 41 activates the sensor unit 42, heating the purified water entering the heating chamber 36. When there is no water flow in the purification chamber 35, the trigger unit 41 deactivates the sensor unit 42, and the heating unit 3 stops heating.

[0075] It should be noted that the control switch 4 can be an inductive switch, that is, the triggering part 41 does not need to be in direct contact with the water flow, and can determine whether there is water flow in the water purification chamber 35 based on vibration or pressure difference. It can also be a contact switch, that is, the inductive part 42 can be triggered when the triggering part 41 is in direct contact with the water flow.

[0076] In a preferred embodiment of this invention, the upper bracket 33 includes a first mounting portion 331, a second mounting portion 332 located below the first mounting portion 331, and a connecting portion 333 connecting the first mounting portion 331 and the second mounting portion 332. Figure 3 and Figure 5 As shown, the top of the first mounting part 331 is recessed downward to form a mounting groove 3311 for mounting the control switch 4. The first mounting part 331 is provided with a second guide channel 3312 that communicates with the first guide channel 3331 and extends toward the trigger part 41.

[0077] In this embodiment, a contact-type flow control switch 4 is selectively used and is mounted on the upper bracket 33. This allows purified water to flow from the outlet 3321 and then through the second guide channel 3312 to contact the trigger part 41. The trigger part 41 is made of a flexible material that deforms under the action of water flow and instantly triggers the sensing part 42. This allows the water entering the heating chamber 36 to receive a longer heating time before being discharged, resulting in a greater temperature rise and a shorter overall water flow path. Furthermore, the space within the upper bracket 33 can be utilized to reduce the length of the water purifier.

[0078] As a preferred option, such as Figure 1 , Figure 3 and Figure 11 As shown, the top of the housing 22 is provided with a top opening 222. The filter unit 2 also includes an upper cover plate 27 for opening or closing the top opening 222, so that the control switch 4 can be disassembled from the upper bracket 33 through the top opening 222 of the housing 22. This allows the control switch 4 to be repaired or replaced without disassembling the heating unit 3 and the filter unit 2 when the control switch 4 malfunctions.

[0079] As a preferred embodiment of this application, such as Figure 1 , Figure 8 and Figure 9 As shown, all the aforementioned embodiments and examples of this application can further include a water circuit plate 25 located inside the housing 22 and detachably disposed below the water purification chamber 35. The water circuit plate 25 integrates the raw water inlet 251, the purified water outlet 252, the raw water inlet channel 253 that connects the raw water inlet 251 and the water inlet 341 respectively, and the purified water outlet channel 254 that connects the heating chamber 36 and the purified water outlet 252 respectively. The raw water inlet 251 extends from inside the housing 22 to communicate with the raw water inlet 11, and the purified water outlet 252 communicates with the outside.

[0080] The water circuit board 25 integrates the raw water inlet 251, the purified water outlet 252, the raw water inlet channel 253, and the purified water outlet channel 254. In other words, the water circuit board 25 integrates all the interfaces, including those for raw water inlet, raw water discharge into the purified water chamber 35, and hot water discharge, thus realizing functional integration and facilitating the modular assembly and disassembly of functional units such as the filter unit 2 and the heating unit 3 within the water purifier.

[0081] Moreover, most of the connections between the water inlets of the water circuit switching unit 1, the filter unit 2, and the heating unit 3 can be made on the water circuit board 25, which avoids the connection between each water inlet through independent pipes, simplifies the pipe structure, reduces mutual interference and avoidance between the pipes and each functional component (heating unit 3, filter unit 2) during installation, and helps to arrange the pipes reasonably. This helps to promote the rationality and compactness of the internal structure of the faucet water purifier, and also facilitates the disassembly and assembly of each component of the filter unit 2 and the heating unit 3.

[0082] As a preferred option, such as Figure 1 and Figure 3 As shown, the filter unit 2 also includes an aerator 28 disposed at the purified water outlet 252 of the water circuit plate 25, so as to achieve the water foaming effect through the dense mesh of the aerator 28.
