Description

Technical Field

[0001] This application relates to the field of drinking water treatment equipment technology, specifically to a mechanical temperature-regulating faucet and an integrated water purifier and heat pump. Background Technology

[0002] Adjustable water temperature faucets play an important role in daily life and many commercial and industrial scenarios, especially in drinking water equipment such as integrated water purifiers and heaters, which can meet people's needs for water at different temperatures.

[0003] Traditional water faucets in integrated water purifiers and heaters mainly consist of a faucet body, a hot water pipe, a normal temperature water pipe, and a spout. The hot water pipe and the normal temperature water pipe are connected to the spout respectively. When hot water is dispensed, the hot water and normal temperature water mix in the spout before being discharged. The conventional way to regulate the temperature of this type of structure is by adjusting the power of the water pump and other program control methods. However, this program-controlled water temperature adjustment method has many obvious drawbacks: On the one hand, the complexity of the program control system itself makes it prone to malfunctions. Once the program fails, such as due to software vulnerabilities or damaged electronic components, the water temperature may not be accurately adjusted, or even the water may not flow properly, causing great inconvenience to users and seriously affecting their user experience. On the other hand, in terms of the accuracy of water temperature adjustment, program control often fails to meet users' expectations for precise water temperature adjustment. In many integrated water purifier and heater products, the program control simply sets a few fixed levels or adjusts based on a wide power range, which is difficult to meet the diverse temperature needs of users in different scenarios. More importantly, program control is lacking in human-computer interaction. During the entire water temperature adjustment process, users can usually only control the water temperature through indirect and relatively abstract operations, such as inputting values ​​on the device's control panel or selecting preset temperature levels. This interaction method lacks intuitiveness and immediate feedback. Users find it difficult to intuitively perceive the real-time connection between their operation and water temperature changes. Unlike operating a mechanical structure, they cannot directly and clearly adjust the water temperature based on tactile and visual feedback. This lack of human-device interaction prevents users from gaining a good sense of participation and control during operation. Utility Model Content

[0004] This application provides a mechanical temperature-regulating faucet, which aims to improve or solve the technical problems of traditional adjustable water temperature faucets, such as high failure rate of water temperature regulation controlled by program, limited temperature settings, and insufficient human-computer interaction.

[0005] The technical solution adopted in this application is as follows:

[0006] A mechanical temperature-regulating faucet includes a faucet housing and a temperature-regulating valve assembly disposed within the faucet housing. The temperature-regulating valve assembly includes a valve upper cover, a valve lower cover, a fixed valve plate, and a movable valve plate. The movable valve plate and the fixed valve plate are coaxially attached and together disposed within an installation cavity formed by the valve upper cover and the valve lower cover. The fixed valve plate is fixedly disposed. The fixed valve plate has a hot water inlet, a normal temperature water inlet, and a water outlet. The side of the fixed valve plate facing the movable valve plate has a normal temperature water flow channel communicating with the normal temperature water inlet and a hot water flow channel communicating with the hot water inlet. The movable valve plate can rotate around its axis. A water flow groove is provided on the side of the movable valve plate facing the fixed valve plate, and one end of the water flow groove is kept in communication with the water outlet. Rotating the movable valve plate can adjust its position to a hot water outlet position, a normal temperature water outlet position, and an adjustment position between the hot water outlet position and the normal temperature water outlet position: in the hot water outlet position, the water flow groove is connected to the hot water inlet; in the normal temperature water outlet position, the water flow groove is connected to the normal temperature water inlet; in the adjustment position, the water flow groove is connected to both the normal temperature water channel and the hot water channel.

[0007] In this technical solution, a temperature regulating valve assembly is installed inside the faucet housing. Utilizing the coaxial fit of the moving and fixed valve plates and the rotatable design of the moving valve plate, along with the hot water inlet, normal temperature water inlet, outlet, normal temperature water flow channel, and hot water flow channel on the fixed valve plate, and a water flow groove on the moving valve plate, the faucet can switch between hot water outlet, normal temperature water outlet, and adjustable positions. In the hot water outlet position, the faucet only dispenses hot water supplied by the hot water inlet; in the normal temperature water outlet position, it only dispenses normal temperature water supplied by the normal temperature water inlet; and in the adjustable position, the faucet dispenses warm water, a mixture of hot water and normal temperature water, flexibly meeting the user's different needs for hot water, normal temperature water, and a mixture of both. Compared to traditional faucets relying on program control, this solution eliminates the need for complex program control, reducing the inconvenience of inaccurate temperature adjustment or even failure to dispense water due to program control malfunction, thus improving the reliability of water temperature regulation and ease of use. Meanwhile, this mechanical adjustment method provides users with an intuitive operating experience, allowing them to clearly understand the water temperature adjustment status during operation. This enhances the interactive experience between people and equipment, giving users a good sense of participation and control. It conveniently meets users' different needs for hot water, room temperature water, and mixed warm water, overcoming the lack of intuitiveness and real-time feedback in traditional program control methods, and improving the overall ease of use.

[0008] The water outlet is located at the axis of the fixed valve plate; along the direction of rotation of the movable valve plate from the hot water outlet position to the normal temperature water outlet position, the cross-sectional area of ​​the normal temperature water flow channel gradually increases, and the cross-sectional area of ​​the hot water flow channel gradually decreases.

[0009] In this technical solution, the water outlet is positioned at the axis of the fixed valve plate, and the cross-sectional areas of the ambient temperature water channel and the hot water channel change regularly along the rotation direction of the moving valve plate. This design allows users to precisely change the flow ratio of hot and ambient temperature water according to the rotation direction when adjusting the water temperature, achieving stepless adjustment of the mixed water temperature. Compared to traditional integrated water purifiers and heaters that rely on fixed gears or wide power range adjustments in program control, this design allows users to more accurately obtain the desired specific temperature of water. For example, it can easily adjust to a precise water temperature close to the human body's comfortable temperature, improving the accuracy of water temperature adjustment and better meeting the diverse and precise water temperature needs of different users in different scenarios.

[0010] The mechanical temperature-regulating faucet also includes a knob and a transmission assembly; the knob is located on the outside of the faucet housing, and the transmission assembly connects the knob and the moving valve plate. The knob, the transmission assembly, and the moving valve plate are circumferentially fixed to transmit the rotational movement of the knob to the moving valve plate.

[0011] This technical solution incorporates a knob and transmission components, ensuring the knob, transmission components, and moving valve plate are circumferentially fixed, thus creating a user-friendly external operation and internal adjustment linkage structure. For users, simply rotating the knob on the outside of the faucet housing easily transmits the rotational motion to the internal moving valve plate, achieving water temperature adjustment; the operation is simple and direct. This convenient and intuitive operation mode greatly improves the ease of water temperature adjustment, allowing users to instantly feel the correlation between operation and water temperature changes, enhancing the human-computer interaction experience.

[0012] The transmission assembly includes a knob seat and a rotating disk structure; the knob seat is pivotally mounted on the outside of the valve cover and fixedly connected to the knob; the rotating disk structure is located in the mounting cavity and includes a rotating shaft and a rotating disk that are coaxially and circumferentially fixedly connected together, the rotating shaft is circumferentially fixedly connected to the knob seat, the rotating shaft is pivotally located on the inside of the valve cover, and the rotating disk and the moving valve plate are circumferentially fixed through the cooperation of a positioning pin and a positioning groove.

[0013] In this technical solution, the transmission component adopts a knob seat and rotating disk structure. Through reasonable pivoting installation and tight fixed connection between various components, especially by utilizing the cooperation of positioning pins and positioning grooves to achieve circumferential fixation of the rotating disk and the moving valve plate, the accuracy and stability of the rotational motion transmission are guaranteed. Moreover, by pivoting the knob seat and rotating shaft to the valve cover on the inner and outer sides respectively, problems such as loosening and jamming during the transmission of the knob's rotational motion to the moving valve plate are effectively avoided. This ensures that the moving valve plate can respond accurately and stably every time the user operates the knob, thereby achieving accurate water temperature adjustment. This allows the entire mechanical temperature-regulating faucet to maintain reliable performance even during frequent use.

[0014] A compression spring is provided between the rotating shaft and the turntable. The compression spring generates an axial clamping force and transmits the axial clamping force to the moving valve plate through the turntable, so that the moving valve plate presses against the fixed valve plate.

[0015] In this technical solution, a compression spring is installed between the rotating shaft and the turntable. The axial clamping force generated by the compression spring presses the moving valve plate firmly against the fixed valve plate, significantly enhancing the sealing between the moving and fixed valve plates. During water temperature adjustment, the reliable sealing effectively prevents water leakage at the contact point between the two valve plates, ensuring that the water flows strictly along the set path. This guarantees the accuracy of water temperature adjustment, eliminating concerns about abnormal water temperature due to leakage or other issues, and consistently achieving the expected water temperature. This creates a favorable operating environment for users and improves the overall product quality.

[0016] The turntable is provided with a limiting boss, and the valve cover is provided with two limiting ribs on the inner side. The two limiting ribs form a space for the limiting boss to rotate. When the limiting boss abuts against one of the limiting ribs, the moving valve plate rotates to the hot water outlet position. When the limiting boss abuts against the other limiting rib, the moving valve plate rotates to the normal temperature water outlet position.

[0017] In this technical solution, two limiting ribs clearly define the two extreme positions of the moving valve plate: the hot water outlet position and the room temperature water outlet position. This design plays an important role in the accuracy of user operation and water temperature adjustment. When the user rotates to adjust the water temperature, they can intuitively feel the adjustment boundary through the contact between the limiting boss and the limiting rib, avoiding unnecessary operational errors caused by excessive rotation, and allowing the user to more accurately obtain the desired hot or room temperature water state.

[0018] Two position switches are installed on the outside of the valve cover, and a trigger part is provided on the knob seat; when the moving valve plate is rotated to the hot water outlet position, the trigger part triggers the contact of one of the position switches; when the moving valve plate is rotated to the normal temperature water outlet position, the trigger part triggers the contact of the other position switch.

[0019] In this technical solution, accurate feedback on the water temperature adjustment status is achieved by the contact between the trigger part and the corresponding switch contact when the moving valve plate rotates to different positions. Users can use this feedback to more intuitively understand the current water temperature adjustment status, such as determining whether it is in hot water or room temperature water output mode. It also provides a reliable reference signal for subsequent possible automated control scenarios or fault detection.

[0020] The lower valve housing is provided with a water outlet channel that connects to the water outlet. A water outlet temperature sensor is installed in the lower valve housing. The detection probe of the water outlet temperature sensor extends into the water outlet channel and is arranged corresponding to the water outlet.

[0021] This technical solution enables real-time monitoring of the outlet water temperature via an outlet water temperature sensor, providing users with an intuitive display of water temperature information. During actual use, users can readily determine if the actual outlet water temperature meets their expectations. Any deviations can be promptly detected and adjusted, overcoming the limitations of traditional program-controlled methods where users lack a clear understanding of the actual water temperature. Furthermore, the monitored temperature data provides strong support for subsequent temperature compensation and adjustment functions, further ensuring the accuracy of the outlet water temperature.

[0022] The lower valve housing is provided with a hot water inlet, a normal temperature water inlet, and a drain outlet. The hot water inlet is connected to the hot water inlet, the normal temperature water inlet is connected to the normal temperature water inlet, and the drain outlet is connected to the water outlet. An integrated sealing body is provided between the fixed valve plate and the lower valve housing. The lower valve housing is provided with a sealing groove that limits the integrated sealing body. The integrated sealing body seals the joint positions of the hot water inlet and the hot water inlet, the joint positions of the normal temperature water inlet and the normal temperature water inlet, and the joint positions of the drain outlet and the water outlet, respectively.

[0023] In this technical solution, an integrated sealing body is installed between the lower valve shell and the fixed valve plate, and a sealing groove is used for limiting the connection. This seals the key joints of the hot water inlet and hot water outlet, the normal temperature water inlet and normal temperature water outlet, and the drain outlet and outlet. Structurally, this comprehensively prevents water leakage at these joints, ensuring the sealing of the water flow inside the entire temperature control valve assembly. This allows the water flow to be stable and orderly along the preset path during water temperature adjustment, avoiding abnormal water temperature or adjustment failure caused by water leakage.

[0024] The present application provides a water purifier and heater, comprising a filter element, a heating element, a booster pump for pressurizing water into the filter element, a cold water pump for drawing water from the filter element into the heating element, and a mechanical temperature-regulating faucet as described above; the purified water outlet of the filter element is connected to the ambient temperature water inlet through an ambient temperature water outlet pipe, and the water outlet of the heating element is connected to the hot water inlet through a hot water outlet pipe.

[0025] In this technical solution, a mechanical temperature-regulating faucet with the aforementioned advantages is applied to an integrated water purifier and heater. Users can conveniently and accurately adjust the water temperature to different levels. Whether it is to directly obtain hot water, room temperature water, or to mix water to meet their specific needs, it becomes easy and can fully meet the diverse water needs of users in different scenarios.

Detailed Implementation

[0055] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0056] In the embodiments of this application, reference is made to Figures 1 to 26 As shown, a mechanical temperature-regulating faucet and an integrated water purifier and heater are provided. For ease of explanation and understanding, the following descriptions are based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is merely a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0057] like Figures 1 to 9As shown, the mechanical temperature-regulating faucet includes a faucet housing 1 and a temperature-regulating valve assembly disposed within the faucet housing 1. The temperature-regulating valve assembly includes a valve upper cover 21, a valve lower cover 22, a fixed valve plate 23, and a movable valve plate 24. The movable valve plate 24 and the fixed valve plate 23 are coaxially attached and disposed together within the mounting cavity formed by the valve upper cover 21 and the valve lower cover 22. The fixed valve plate 23 is fixedly disposed. The fixed valve plate 23 has a hot water inlet 231, a normal temperature water inlet 232, and a water outlet 233. The side of the fixed valve plate 23 facing the movable valve plate 24 has a normal temperature water flow channel 234 connecting to the normal temperature water inlet 232 and a hot water flow channel connecting to the hot water inlet 231. Channel 235; The movable valve plate 24 can rotate around its axis. The movable valve plate 24 is provided with a water flow groove 241 on the side facing the fixed valve plate 23. One end of the water flow groove 241 is kept in corresponding communication with the water outlet 233. Rotating the movable valve plate 24 can make it be in an adjustable position between the hot water outlet position, the normal temperature water outlet position, and the hot water outlet position and the normal temperature water outlet position: In the hot water outlet position, the water flow groove 241 is connected to the hot water inlet 231; In the normal temperature water outlet position, the water flow groove 241 is connected to the normal temperature water inlet 232; In the adjustable position, the water flow groove 241 is connected to both the normal temperature water flow channel 234 and the hot water flow channel 235.

[0058] The mechanical temperature-regulating faucet of this application, by setting the temperature-regulating valve assembly inside the faucet housing 1, and the temperature-regulating valve assembly including valve upper cover 21, valve lower housing 22, fixed valve plate 23 and moving valve plate 24, the fixed valve plate 23 and the moving valve plate 24 are coaxially attached and placed in the mounting cavity and the fixed valve plate 23 is fixed, thus establishing a stable and reliable basic structure for water temperature regulation.

[0059] Specifically, the fixed valve plate 23 has a hot water inlet 231, a normal temperature water inlet 232, and an outlet 233 that are arranged through it. In actual application in the integrated water purifier and heat pump, the hot water inlet 231 and the normal temperature water inlet 232 can be connected to the upstream hot water supply device and the normal temperature water supply device respectively through water pipes. For example, the hot water inlet 231 is connected to the heating element through a water pipe, and the normal temperature water inlet 232 is connected to the purified water outlet of the filter element through another water pipe. The side of the fixed valve plate 23 facing the movable valve plate 24 is connected to the hot water flow channel 235 of the hot water inlet 231 and the normal temperature water flow channel 234 of the normal temperature water inlet 232. With the movable valve plate 24 rotating around its axis and the water flow groove 241 that is always connected to one end of the outlet 233, a variety of water temperature adjustment functions are realized. Figure 11 , Figure 12 and Figure 13 The diagram illustrates the engagement of the moving valve plate 24 and the stationary valve plate 23. Because the views of the hot water inlet 231, the ambient temperature water inlet 232, the outlet 233, the hot water flow channel 235, the ambient temperature water flow channel 234, and the water flow groove 241 are obstructed by the outer surfaces of the moving valve plate 24 and the stationary valve plate 23, they are represented by dashed lines. Figure 11The illustration shows the state in which the moving valve plate 24 is positioned at the hot water outlet, connecting the water flow channel 241 with the hot water inlet 231; Figure 12 The illustration shows the state in which the moving valve plate 24 is positioned at the normal temperature water outlet position, connecting the water flow channel 241 with the normal temperature water inlet 232; Figure 13 The illustration shows the state in which the moving valve plate 24 is in the adjustment position, so that the water flow channel 241 is simultaneously connected to the normal warm water flow channel 234 and the hot water flow channel 235.

[0060] In practical use, when a user needs hot water, simply rotate the valve plate 24 to the hot water outlet position. At this time, the water flow channel 241 connects with the hot water inlet 231, and the heated water can flow smoothly out through the hot water inlet 231, the water flow channel 241, and the outlet 233, meeting the user's needs for scenarios requiring higher-temperature hot water, such as brewing coffee or tea. When room temperature water is needed, rotate the valve plate 24 to the room temperature water outlet position, and the water flow channel 241 connects with the room temperature water inlet 232. Room temperature purified water can then flow out from the room temperature water inlet 232, the water flow channel 241, and the outlet 233, suitable for direct drinking or simple washing. When warm water is desired, rotate the valve plate 24 to the adjustment position, so that the water flow channel 241 connects simultaneously to the normal warm water channel 234 and the hot water channel 235. Hot water and room temperature water are mixed in a certain proportion and then discharged, providing comfortable warm water, such as in daily washing scenarios like handwashing and face washing.

[0061] This method of manually adjusting water temperature through a mechanical structure avoids the problems of uncontrolled water temperature or no water flow caused by the complexity of the program and its potential for malfunction. It ensures normal use for users, stably obtains the required water temperature, improves the reliability and stability of use, and the operation process is intuitive. Users can clearly see the real-time changes in water temperature adjustment, enhancing the interactive experience between people and the device, making it more convenient and flexible to use.

[0062] As a preferred embodiment of this application, such as Figure 7 and Figure 8 As shown, the outlet 233 is located at the axis of the fixed valve plate 23; along the direction of rotation of the movable valve plate 24 from the hot water outlet position to the normal temperature water outlet position, the cross-sectional area of ​​the normal temperature water flow channel 234 gradually increases, while the cross-sectional area of ​​the hot water flow channel 235 gradually decreases. Figure 7Taking the state shown as an example, in the counterclockwise direction, the cross-sectional area of ​​the normal temperature water flow channel 234 gradually increases, while the cross-sectional area of ​​the hot water flow channel 235 gradually decreases. The moving valve plate 24 rotates counterclockwise from the hot water outlet position to the normal temperature water outlet position. In actual water temperature adjustment, this design brings significant advantages. For example, if a user wants to gradually lower the water temperature from a hot state to a suitable warm water temperature, they only need to rotate the moving valve plate 24 in the corresponding direction. As the moving valve plate 24 rotates, because the cross-sectional area of ​​the hot water flow channel 235 gradually decreases, the hot water flow rate will gradually decrease accordingly, while the cross-sectional area of ​​the normal temperature water flow channel 234 gradually increases, and the normal temperature water flow rate gradually increases. The resulting mixture of the two waters will lower the temperature smoothly and subtly. Conversely, to raise the water temperature, rotating the moving valve plate 24 in the opposite direction will increase the hot water flow rate and decrease the normal temperature water flow rate, thereby precisely raising the water temperature. This linear and precise water temperature regulation method, achieved through a mechanical structure, stands in stark contrast to the traditional integrated water purifier and heater that relies on a few fixed settings or a wide power range for temperature adjustment. It can meet users' needs for precise water temperature control, such as 38℃ or 42℃. In different usage scenarios, whether it is for strictly controlling the water temperature when preparing baby formula or for adjusting the water temperature for personal washing according to preference, it can provide a more precise water temperature regulation effect that meets user expectations, greatly improving user satisfaction with water temperature regulation and the practicality of the product.

[0063] As a preferred embodiment of this application, such as Figure 1 , Figure 2 and Figure 3As shown, the mechanical temperature-regulating faucet also includes a knob 3 and a transmission assembly. The knob 3 is located on the outside of the faucet housing 1, and the transmission assembly connects the knob 3 to the moving valve plate 24. The knob 3, the transmission assembly, and the moving valve plate 24 are circumferentially fixed to transmit the rotational movement of the knob 3 to the moving valve plate 24. Preferably, the front side of the faucet housing 1 is used for water, so the temperature-regulating valve assembly can be arranged on the rear side of the faucet housing 1, corresponding to the knob 3 being set on the top of the rear side of the faucet housing 1. The moving valve plate 24 can also be attached to the upper side of the fixed valve plate 23 to facilitate the torque transmission between the knob 3 and the moving valve plate 24, and also to facilitate the connection between the water inlet structure below the faucet and the various water outlets on the fixed valve plate 23. By adding the knob 3 and the transmission assembly, the transmission assembly circumferentially fixes the knob 3 and the moving valve plate 24, thus creating a convenient linkage mechanism for external operation and internal adjustment. In actual use, users can stand in front of the faucet without bending over or performing complicated operations. Simply rotate the knob 3 on the outside, and the rotational motion will be accurately transmitted to the internal moving valve plate 24 through the transmission component, thereby adjusting the water temperature. Compared to traditional faucets that rely on program control, which require relatively abstract and indirect operations such as inputting values ​​and selecting preset levels on the device's control panel, this operation is more intuitive and simple. Users can instantly feel the correlation between their hand movements and water temperature changes, enhancing the human-computer interaction experience and making water temperature adjustment easy and natural. It is especially convenient for different groups such as the elderly and children, fully demonstrating the ease of operation and improving user comfort and sense of control during use.

[0064] Furthermore, regarding the structure of the transmission components, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 19As shown, it includes a knob seat 4 and a rotating disk 6 structure. The knob seat 4 is pivotally mounted on the outside of the valve cover 21 and fixedly connected to the knob 3. The rotating disk 6 structure is located in the mounting cavity and includes a rotating shaft 5 and a rotating disk 6 that are coaxially and circumferentially fixedly connected together. The rotating shaft 5 is circumferentially fixedly connected to the knob seat 4 and pivots on the inside of the valve cover 21. The rotating disk 6 and the moving valve plate 24 are circumferentially fixed through the cooperation of the positioning pin 61 and the positioning groove 242. By forming a fixed structure between the knob 3 and the knob seat 4 and pivoting the knob seat 4 on the outside of the valve cover 21, and forming a fixed structure between the rotating shaft 5 and the rotating disk 6 and pivoting the rotating shaft 5 on the inside of the valve cover 21, and then circumferentially fixedly connecting the rotating shaft 5 to the knob seat 4, the installation and positioning of each component becomes clearer and more convenient. Assembly workers can easily and accurately install these components according to the established installation process, and through the corresponding pivot structure cooperation, they can easily perform debugging and inspection to ensure the normal function of the entire transmission assembly. During subsequent product maintenance, if it is necessary to inspect or replace components such as the knob seat 4 and rotating shaft 5, this relatively independent and clearly defined pivoting installation method facilitates quick disassembly and reinstallation of the corresponding components by maintenance personnel, improving maintenance efficiency and reducing maintenance time and costs. Furthermore, pivoting the knob seat 4 and rotating shaft 5 on the outer and inner sides of the valve cover 21 respectively allows for the reasonable distribution and transmission of forces during operation. When the user applies rotational force, the force is transmitted systematically through components such as the knob seat 4 and rotating shaft 5. The pivoting connection between components effectively buffers and disperses potential impact forces and uneven force distribution, reducing the risk of component damage due to excessive localized force. Moreover, this installation method helps maintain the stability of the relative positions of the components. Under long-term use and frequent rotation, it prevents issues such as loosening or misalignment of components from affecting the accuracy of transmission, thereby ensuring the reliability of the entire mechanical temperature-regulating faucet, effectively extending the product's service life, and reducing maintenance costs. When the user rotates knob 3, knob base 4 rotates accordingly, transmitting the rotational motion to turntable 6 via rotating shaft 5. Due to the precise fixed connection between turntable 6 and moving valve plate 24, moving valve plate 24 can rotate synchronously with the rotation direction and angle of knob 3, avoiding problems such as loosening, jamming, or inaccurate transmission ratio during the transmission process. For example, during frequent use of the faucet to adjust water temperature, whether the user rotates knob 3 quickly or makes slow fine adjustments, moving valve plate 24 can respond accurately, ensuring the accuracy and stability of water temperature adjustment, and preventing fluctuations in water temperature due to transmission deviations.

[0065] Regarding the pivotal mounting of the knob seat 4 and the rotating shaft 5 on the outer and inner sides of the valve cover 21, respectively, in a preferred embodiment, the valve cover 21 can have a hollow convex shaft protruding upwards, and the knob seat 4 can have a cavity adapted to this convex shaft, with the convex shaft and the cavity pivotally fitted. Furthermore, the rotating shaft 5 can pivot directly on the inner side of the convex shaft, and some sealing structures can be provided between the two to prevent leakage. Regarding the fixing method of the knob seat 4 and the knob 3, a D-shaped groove can be provided on the knob seat 4, with a slot inside the D-shaped groove, and a D-shaped post can be provided on the knob 3, with a buckle on the D-shaped post. After the D-shaped post enters the D-shaped groove, the buckle engages with the slot. Regarding the circumferential fixed connection between the rotating shaft 5 and the knob seat 4, such as... Figure 6 , Figure 15 and Figure 17 As shown, a flat post 41 can be provided inside the knob seat 4, and a corresponding flat groove 51 can be provided on the rotating shaft 5. The flat post 41 passes through the valve cover 21 and is inserted into the flat groove 51. Regarding the method of coaxially fixing the rotating shaft 5 and the turntable 6 together, as shown... Figure 16 and Figure 18 As shown, limiting ribs 52 extending to both sides can be provided on the rotating shaft 5, and a long strip-shaped limiting slot 62 adapted to the limiting ribs 52 can be provided at the center of the turntable 6. The limiting ribs 52 are inserted into the limiting slots 62 to achieve circumferential fixation. After the valve upper cover 21 and the valve lower shell 22 are fitted together, the rotating shaft 5, the turntable 6, the moving valve plate 24, and the fixed valve plate 23 are pressed together to prevent these components from shaking up and down. Regarding the fixing method of the fixed valve plate 23, in addition to axial fixation by the pressing of the moving valve plate 24 from above, such as... Figure 8 and Figure 23 As shown, a positioning groove 236 can also be provided on the fixed valve plate 23, and a positioning protrusion 221 can be provided on the lower valve shell 22. The positioning groove 236 and the positioning protrusion 221 cooperate to fix the fixed valve plate 23 circumferentially, and the outer ring surface of the fixed valve plate 23 abuts against the lower valve shell 22 to achieve radial fixation.

[0066] In a preferred embodiment, such as Figure 6 , Figure 16 and Figure 20As shown, a compression spring 7 is provided between the rotating shaft 5 and the turntable 6. The compression spring 7 generates an axial clamping force and transmits this force through the turntable 6 to the moving valve plate 24, causing the moving valve plate 24 to press against the fixed valve plate 23. Specifically, a radial annular protrusion 53 can be provided on the rotating shaft 5, and the compression spring 7 is sleeved on the rotating shaft 5 and sandwiched between the radial annular protrusion 53 and the upper surface of the turntable 6. On the one hand, the compression spring 7 enhances the tightness of the fit between the moving valve plate 24 and the fixed valve plate 23, effectively preventing water leakage at the joint of the two valve plates. For example, when the water pressure in the faucet is high or after prolonged use, due to the continuous clamping action of the compression spring 7, the water flow can still be guaranteed to strictly follow the preset hot water flow channel 235, the normal temperature water flow channel 234, and the corresponding inlet and outlet paths, avoiding problems such as abnormal water temperature changes or uncontrolled water flow caused by leakage, and ensuring the accuracy and stability of water temperature regulation. On the other hand, a good sealing effect also helps to extend the product's service life and reduce potential risks such as damage to internal components caused by water leakage. Compared with traditional program-controlled faucets, which may affect water temperature regulation and overall product performance due to poor sealing, this design further improves the reliability and durability of mechanical temperature-regulating faucets, making it more worry-free for users and eliminating the need to frequently worry about various usage problems caused by water leakage.

[0067] In a preferred embodiment, such as Figure 18 , Figure 21 and Figure 22As shown, the turntable 6 is provided with a limiting boss 63, and the inner side of the valve cover 21 is provided with two limiting ribs 211. The two limiting ribs 211 enclose a space for the limiting boss 63 to rotate. When the limiting boss 63 abuts against one of the limiting ribs 211, the moving valve plate 24 rotates to the hot water outlet position; when the limiting boss 63 abuts against the other limiting rib 211, the moving valve plate 24 rotates to the room temperature water outlet position. The abutment between the limiting boss 63 and the limiting rib 211 clearly defines the two extreme positions of the moving valve plate 24, namely the hot water outlet position and the room temperature water outlet position. More preferably, in order to maximize the rotation range of the knob 3 and achieve temperature adjustment within a large angle, the limiting boss 63 can be set within the superior arc range enclosed by the two limiting ribs 211. In the user's daily water temperature adjustment process, this limit design provides clear and intuitive operation guidance. For example, when the user wants hot water, rotating knob 3 causes valve plate 24 to rotate. When the limit protrusion 63 abuts against the corresponding limit rib 211, the user knows that the hot water outlet position has been reached, and the faucet will steadily flow hot water, avoiding mechanical damage or water temperature adjustment chaos caused by excessive rotation. Similarly, when room temperature water is needed, rotating knob 3 in the opposite direction until the limit protrusion 63 abuts against another limit rib 211 will accurately provide room temperature water. This not only makes it convenient for users to quickly and accurately obtain the desired water temperature, but also, compared to the traditional program control method where users find it difficult to accurately know the water temperature adjustment boundary and are prone to misoperation, this design makes water temperature adjustment more precise and controllable, improving the convenience and accuracy of user operation, and enhancing user confidence and satisfaction during use.

[0068] In a preferred embodiment, such as Figure 4 , Figure 5 and Figure 14 As shown, two position switches 8 are installed on the outside of the valve cover 21, and a trigger part 42 is provided on the knob seat 4. When the moving valve plate 24 is rotated to the hot water outlet position, the trigger part 42 triggers the contact of one of the position switches 8; when the moving valve plate 24 is rotated to the room temperature water outlet position, the trigger part 42 triggers the contact of the other position switch 8. In actual use, this design provides users with clear feedback on the water temperature adjustment status. For example, when the user rotates the knob 3 to adjust the water temperature, if the trigger part 42 triggers one of the position switches 8, the faucet can inform the user that it is currently in the hot water outlet position by illuminating an indicator light or emitting a prompt sound, allowing the user to intuitively know the result of the water temperature adjustment. Similarly, there will be a corresponding prompt when switching to the room temperature water outlet position. Moreover, in the integrated water purifier and heater, the control system will also control the system to enter the hot water outlet mode and the room temperature water outlet mode according to the triggering state of the two position switches 8 by the trigger part 42. In the corresponding mode, the water outlet button can be pressed to start the hot water or room temperature water.

[0069] As a preferred embodiment of this application, such as Figure 6 As shown, the lower valve housing 22 has a water outlet channel 222 connected to the water outlet 233. A water temperature sensor 9 is installed in the lower valve housing 22, with its detection probe 91 extending into the water outlet channel 222 and corresponding to the water outlet 233. When the user turns on the faucet to adjust the water temperature, the water temperature sensor 9 can monitor the actual temperature of the flowing water in real time and provide feedback (the data can be displayed on a screen or similar means). For example, if the user originally intended to adjust the water temperature to 40℃ for washing their face, they can precisely adjust the rotation angle of the moving valve plate 24 by viewing the real-time temperature value during the adjustment process, making the water temperature closer to their desired temperature. If the water temperature is too high or too low, it can be fine-tuned in time. Compared with traditional program-controlled faucets, users no longer blindly adjust according to preset levels, but can precisely control the water temperature based on the actual temperature, improving the accuracy of water temperature adjustment and better meeting the diverse and precise water temperature needs of users in different scenarios.

[0070] As a preferred embodiment of this application, such as Figure 6 , Figure 23 and Figure 24As shown, the lower valve housing 22 is provided with a hot water inlet 223, a normal temperature water inlet 224, and a drain outlet 225. The hot water inlet 231 is connected to the hot water inlet 223, the normal temperature water inlet 232 is connected to the normal temperature water inlet 224, and the drain outlet 225 is connected to the outlet 233. An integrated sealing body 101 is provided between the fixed valve plate 23 and the lower valve housing 22. The lower valve housing 22 is provided with a sealing groove 226 that limits the integrated sealing body 101. The integrated sealing body 101 seals the joint positions of the hot water inlet 231 and the hot water inlet 223, the normal temperature water inlet 232 and the normal temperature water inlet 224, and the joint position of the drain outlet 225 and the outlet 233, respectively. In this embodiment, the lower valve housing 22 forms an intermediate structure for supplying water to the temperature regulating valve assembly from the upstream normal temperature water supply device and the hot water supply device, facilitating pipeline connection. A room temperature water supply device (such as a filter element) can be connected to a room temperature water inlet 224 via a water pipe. During water supply, room temperature water enters the room temperature water inlet 232 through the room temperature water inlet 224. A hot water supply device (such as a heating element) can be connected to a hot water inlet 223 via a water pipe. During water supply, hot water enters the hot water inlet 231 through the hot water inlet 223. An integrated sealing body 101 is provided between the fixed valve plate 23 and the lower valve shell 22, and is limited by the sealing groove 226, thereby sealing the joint positions of the hot water inlet 231 and the hot water inlet 223, the room temperature water inlet 232 and the room temperature water inlet 224, and the drain outlet 225 and the outlet 233, respectively. In daily use, whether the faucet is left on for extended periods or frequent temperature changes cause fluctuations in internal water pressure, this sealing structure effectively prevents water leakage from key joints. It reliably ensures that the internal water flows along the predetermined path, avoiding problems such as slippery floors and equipment damage caused by leaks. This ensures stable operation of the water temperature regulation function and maintains accurate water temperature. Furthermore, compared to using separate sealing bodies at each joint, the integrated sealing body 101 combines the sealing functions of multiple parts into a single body, simplifying the structure and facilitating assembly.

[0071] The integrated air purifier and heating unit provided in this application, such as Figure 25 As shown, the system includes a filter element 102, a heating element 103, a booster pump 104 for pressurizing water supply to the filter element 102, a cold water pump 105 for drawing water from the filter element 102 into the heating element 103, and a mechanically temperature-controlled faucet as described above. The purified water outlet of the filter element 102 is connected to the normal temperature water inlet 232 via a normal temperature water outlet pipe 106, and the water outlet 233 of the heating element 103 is connected to the hot water inlet 231 via a hot water outlet pipe 107. Furthermore, Figure 25The diagram also shows that the integrated water purifier and heater is equipped with a wastewater solenoid valve 108 for controlling wastewater discharge, a water inlet solenoid valve 109 for controlling water inlet, a one-way valve 110 for controlling the one-way backflushing filter element 102, and a pressure reducing valve 120 for controlling the water supply to the heating element 103. When the knob 3 and the knob seat 4 are rotated until the trigger part 42 of the knob seat 4 presses against the contact of the position switch 8 corresponding to the normal temperature water outlet position, the water flow groove 241 of the moving valve plate 24 is only connected to the normal temperature water inlet 232. At this time, when the button is pressed to dispense water, the water inlet solenoid valve 109 is opened, the booster pump 104 is working, and the tap water flows through the water inlet solenoid valve 109. After being pressurized by the booster pump 104, it enters the filter element 102. After being filtered by the filter element 102, it flows from the normal temperature water outlet pipe to the faucet, and then flows through the normal temperature water inlet of the lower valve shell 22, the normal temperature water inlet 232 of the fixed valve plate 23, the water flow groove 241, the water outlet 233 of the fixed valve plate 23, and the water outlet channel 222 of the lower valve shell 22 to the water outlet 130, and finally is discharged through the water outlet 130. When the knob 3 and the knob seat 4 are rotated until the trigger part 42 of the knob seat 4 presses against the contact of the position switch 8 corresponding to the hot water outlet position, the water flow channel 241 of the moving valve plate 24 is only connected to the hot water inlet 231. At this time, the button is pressed to release water. The hot water produced by the heating element 103 flows to the faucet through the hot water outlet pipe 107, and flows through the hot water inlet 223 of the lower valve shell 22, the hot water inlet 231 of the fixed valve plate 23, the water flow channel 241, the outlet 233 of the fixed valve plate 23, and the outlet flow channel 222 of the lower valve shell 22 to the water outlet 130, and finally is discharged through the water outlet 130. When the knob 3 and the knob seat 4 are rotated until the trigger part 42 of the knob seat 4 disengages from the contacts of the two position switches 8, the water flow channel 241 of the moving valve plate 24 connects the normal temperature water flow channel 234 and the hot water flow channel 235. At this time, the button is pressed to dispense water. The hot water produced by the heating element 103 flows to the faucet through the hot water outlet pipe 107, and the room temperature water produced by the filter element 102 flows to the faucet through the room temperature water outlet pipe. The hot water and room temperature water mix in the water flow channel 241 and flow through the outlet 233 of the fixed valve plate 23 and the outlet flow channel 222 of the lower valve shell 22 to the water outlet 130, and finally are discharged through the water outlet 130.

[0072] Furthermore, in a preferred embodiment, such as Figure 26As shown, the integrated water purifier and heater can also include a heat preservation device 140. The heat preservation device 140 forms a circulating heating and heat preservation structure with the hot water pump 150, the reversing valve 160 and the heating element 103. The two outlets of the reversing valve 160 are respectively connected to the heat preservation device 140 and the hot water outlet pipe 107. That is, when the reversing valve 160 is connected to the heat preservation device 140, the hot water heated by the heating element 103 can enter the heat preservation device 140 for heat preservation through the reversing valve 160. When the user takes water, the reversing valve 160 switches to connect to the hot water outlet pipe 107. The heating element 103 does not need to heat the room temperature water output by the filter element 102, but can send the heat preservation water in the heat preservation device 140 back to the heating element 103 for heating, and then send it to the faucet through the reversing valve 160, which greatly shortens the heating time and improves the hot water output response capability.
