Description

Technical Field

[0001] This invention relates to the field of faucets, and more particularly to a fluid distributor, faucet, and water supply system. Background Technology

[0002] To meet the needs of fluid temperature control in daily water use scenarios, faucets typically need to achieve the mixing and stable output of multiple fluids (such as cold water and hot water). In this process, the stable connection of the tap water pipes and the accurate detection of the mixed fluid temperature are key aspects to ensure a good user experience. In existing faucet designs, pipe limiting and fixing structures are usually used to constrain the pipe position and prevent fluid delivery obstruction or leakage due to pipe displacement.

[0003] However, in existing technologies, the design of pipe limiting and fixing structures often fails to adequately consider the installation space and detection requirements of temperature sensing elements. This results in the temperature sensing elements being unable to capture the actual temperature of the mixed fluid in real time and accurately, leading to a significant deviation between the detected temperature and the true temperature of the mixed fluid. This temperature deviation directly affects the accuracy of subsequent water temperature regulation mechanisms, preventing them from making targeted adjustments based on the true temperature of the mixed fluid. Ultimately, this results in large temperature fluctuations in the faucet's output fluid, making it difficult to maintain a stable temperature range required by the user. This affects the convenience of use in daily washing and cleaning scenarios and may also cause discomfort due to sudden temperature changes, thus restricting the overall functional reliability and user experience of the faucet. Summary of the Invention

[0004] In order to overcome at least one of the defects described in the prior art, the present invention provides a fluid distributor, a faucet and a water supply system. The existing faucet's pipeline limiting and fixing structure is not fully adapted to the installation and detection requirements of the temperature detection element, resulting in technical problems such as large temperature detection deviation and fluctuation in output fluid temperature.

A pipe clamp is provided on the base. The base is fitted over the outside of the top seat, forming an outlet channel, a return channel, a hot water channel, and a room temperature water channel. The hot water channel and the room temperature water channel are both connected to the outlet channel. The pipe clamp is located on the outside of the top seat and is used to limit and fix the water pipes, which are independently configured for the outlet channel, hot water channel, and room temperature water channel. The solenoid valve and the temperature sensing element are both installed on the top seat. The solenoid valve is located on the outlet channel, the hot water channel, or... The connection position between the outlet of the hot water channel and the inlet of the liquid outlet channel is used to control the opening and closing of the passage to the liquid outlet channel; and a temperature sensing element is disposed on the hot water channel to detect the temperature of the hot water flowing through it, and the temperature sensing element cooperates with the solenoid valve to control the solenoid valve to open so as to output hot water from the liquid outlet channel when the temperature detected by the temperature sensing element reaches a preset temperature or is within a preset temperature range; when the temperature does not reach the preset temperature or is outside the preset temperature range, the solenoid valve is controlled to close and the hot water is discharged through the return channel.

[0006] In some embodiments of the present invention, one of the top seat and the base is provided with a buckle protrusion, and the other of the top seat and the base is provided with a limiting slot, wherein the buckle protrusion engages with the limiting slot.

[0007] In some embodiments of the present invention, the top seat includes an integrally connected main body and a plurality of branch parts. The main body is provided with a main channel cavity and a main outlet aligned with the main channel cavity. The main channel cavity and the main outlet constitute the liquid outlet channel. Each branch part is provided with a branch flow channel cavity that is part of the hot water channel. Each branch flow channel cavity is connected to the main channel cavity. The base includes a bottom wall and a sleeve wall protruding to one side. A branch opening belonging to a part of the hot water channel is provided on the bottom wall. The sleeve wall abuts against and covers at least part of the outer peripheral side of the main body and the outer peripheral side of each branch. The main opening communicates with the main flow channel cavity, and the branch opening communicates with the branch flow channel cavity.

[0008] In some embodiments of the present invention, the portion of the bottom wall protruding from the peripheral side of the top seat is formed as the pipe clamp portion, and the pipe clamp portion is provided with a clamp through groove that opens radially toward the bottom wall.

[0009] In some embodiments of the present invention, a connecting portion is provided between two adjacent branches and / or between the main body and the branch, and a connecting hole is provided on the side of the connecting portion near the bottom wall, the bottom wall is connected to the connecting hole by a fastener, and an inserting space is provided on the sleeve wall to accommodate the connecting portion.

[0010] In some embodiments of the present invention, the temperature sensing element is located upstream of the solenoid valve along the flow direction of the liquid, and the solenoid valve is located on the liquid outlet channel to control the opening and closing of the liquid outlet channel and the flow rate of the fluid output from the liquid outlet channel.

[0011] In some embodiments of the present invention, the temperature sensing element is disposed adjacent to the solenoid valve, and the top seat is provided with a valve cavity communicating with the liquid outlet channel. The detection end of the temperature sensing element is disposed in the valve cavity or at the intersection of the hot water channel and the liquid outlet channel.

[0012] In some embodiments of the present invention, a pressure stabilizing channel is further provided inside the distributor body, the hot water channel is connected to the hot water channel through the pressure stabilizing channel, and the detection end of the temperature measuring element extends into the interior of the pressure stabilizing channel.

[0015] In summary, the fluid distributor, faucet, and water supply system provided by this invention have the following technical advantages: The fluid distributor is detachably connected to the top and base of the main body, providing flexible space for pipeline layout and temperature sensing element installation and debugging. By placing the pipe clamp for limiting and fixing the water pipe on the base of the main body, reliable limiting of water pipes independently configured with liquid outlet and hot water channels can be achieved. This avoids pipeline displacement affecting stable fluid delivery and provides sufficient and suitable space for the placement of temperature sensing elements. Furthermore, by fitting the base onto the outside of the top, the top and base cooperate to form interconnected hot water and liquid outlet channels, ensuring the independence and stability of multiple fluid delivery streams. At the same time, the temperature sensing element and the solenoid valve for regulating fluid supply are installed together on the top, allowing the temperature sensing element to be close to the fluid delivery path and accurately capture fluid temperature information in real time. This effectively reduces the deviation between the detected temperature and the actual temperature. Based on this accurate temperature data, the solenoid valve can perform targeted control actions, thus solving the problems of temperature detection deviation and output temperature fluctuation caused by insufficient adaptation between pipeline limiting structure and temperature detection requirements in existing technologies, ensuring that the faucet output fluid temperature remains within a stable range.

Detailed Implementation

[0018] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] A faucet is used to control the flow of water and connects the water supply system to the user (such as an electric kettle), providing users with a convenient and controllable way to obtain fluids to meet the fluid usage needs of different scenarios. For example, in daily life, it can be used for household washing, kitchen cleaning, and bathroom water use, while in commercial scenarios, it can be used for tableware cleaning in the catering industry and water supply in public places. However, most existing faucets use a single delivery path, enabling the output of fluid from only one source and lacking an effective mechanism for controlling the temperature of the mixed fluid. When the supply pressure of different fluid sources fluctuates, or when the initial temperatures of different fluid sources differ, the temperature of the mixed fluid is prone to unstable fluctuations. These fluctuations not only require users to repeatedly adjust the faucet to try and obtain the desired fluid temperature, increasing operational complexity, but may also affect the user experience due to unstable temperature.

[0022] Based on the problems mentioned above, please refer to the specific details. Figures 1 to 3 As shown, this technical solution provides a fluid distributor 100 applied to a faucet 1000. The fluid distributor 100 includes a distributor body 110, a solenoid valve 112, a temperature sensing element 113, and a control unit. The distributor body 110 is internally provided with an outlet channel 1111, a return channel 1113, and two independent hot water channels 1112 and 1116. The independence here specifically means that the hot water channel 1112 and the 1116 each have independent fluid transport paths. The hot water channel 1112 and the 1116 are not directly connected and there is no fluid exchange or interference. The hot water channel 1112 and the 1116 are only responsible for transporting fluid from their respective sources. Changes in the pressure, flow rate, temperature, and other parameters of the fluid in one of the hot water channel 1112 and the 1116 will not directly affect the fluid transport status of the other of the hot water channel 1112 and the 1116. In this embodiment, the hot water channel 1112 and the room temperature water channel 1116 are each connected to different external water supply units, and can receive and transport fluids from different sources respectively. The ends of the hot water channel 1112 and the room temperature water channel 1116 are connected to the liquid outlet channel 1111, so that fluids from different sources can be introduced independently before the liquid outlet channel 1111, and the liquid outlet channel 1111 can achieve independent or on-demand switching output.

[0023] In practical applications, both the water supply unit and the faucet 1000 mentioned above are part of the water supply system. The water supply unit can be a municipal cold water supply network, which can stably deliver tap water that meets the basic water standards for domestic or industrial use; it can also be a water source heater for gas water heaters or electric water heaters, which can provide heated water with controllable temperature; it can also be a water purifier, which can output purified water; or it can be a storage-type water supply device.

[0024] The solenoid valve 112 is mounted on the distributor body 110 and is located on the liquid outlet channel 1111, the hot water channel 1112, or at the connection position between the outlet of the liquid outlet channel 1111 and the inlet of the hot water channel 1112. The solenoid valve 112 can switch the flow state of the liquid outlet channel 1111 based on a preset command or detection signal.

[0025] Temperature sensing element 113 is also mounted on the distributor body 110 and located on the hot water channel 1112. The sensing end of the temperature sensing element 113 is in direct or indirect contact with the fluid in the outlet channel 1111, and can sense and acquire the temperature information of the fluid supplied through several hot water channels 1112 in real time, providing data support for the regulation of fluid output.

[0026] The control unit is electrically connected to the temperature sensing element 113 and the solenoid valve 112. The control unit is configured to: when the temperature detected by the temperature sensing element 113 reaches the preset temperature or is within the preset temperature range, control the solenoid valve 112 to open to output hot water from the liquid outlet channel 1111; when the temperature does not reach the preset temperature or is outside the preset temperature range, control the solenoid valve 112 to close and allow the hot water to be discharged through the return channel 1113.

[0027] In the above, the hot water channel 1112 and the ambient temperature water channel 1116 respectively transport fluids from different sources, avoiding the situation where different fluids interfere with each other during the supply process due to pressure fluctuations or initial temperature differences, which directly leads to temperature instability. This ensures that each fluid is transported independently before entering the outlet channel 1111, laying the foundation for subsequent temperature screening. The solenoid valve 112 can control the opening and closing of the outlet channel 1111 based on the temperature information obtained by the temperature sensing element 113. Specifically, the solenoid valve 112 performs targeted control based on the hot fluid temperature information of the hot water channel 1112 obtained by the temperature sensing element 113. When it is detected that the hot fluid temperature in the hot water channel 1112 has not reached the preset temperature value, the solenoid valve 112 will block and discharge the substandard fluid in the hot water channel 1112, allowing only the fluid with the preset temperature to independently enter the outlet channel 1111 for output. The fluid in the room temperature water channel 1116 is closed according to user needs, and the fluid in the hot water channel and the room temperature water channel 1116 do not mix. Instead of adjusting the flow rate to change the mixing ratio to correct the temperature, the problem of substandard hot fluid affecting the output temperature is eliminated from the source. This effectively solves the temperature fluctuation problem caused by the inability to control the output fluid temperature of the existing faucet 1000. Stable output fluid temperature can be obtained without repeated adjustments by the user, reducing the tediousness of repeated adjustments by the user. It achieves precise control of the output fluid temperature, ensuring that the output fluid temperature is maintained within the expected range, meeting the needs of application scenarios that require fluid temperature stability, improving the user experience, and increasing ease of use.

[0028] In this embodiment, please refer to the specific details. Figure 4As shown, the faucet 1000 includes the aforementioned fluid distributor 100 and faucet body 200. The faucet body 200 is equipped with a water outlet nozzle 210 and a tap water nozzle 220. The tap water nozzle 220 is positioned outside the projection range formed by the water outlet nozzle 210 along its water outlet direction. In short, the water outlet coverage areas of the tap water nozzle 220 and the water outlet nozzle 210 do not overlap, and the water from the tap water nozzle 220 will not fall into the receiving area covered by the water from the water outlet nozzle 210. For example, the water nozzle 210 is installed on the faucet body 200 near the lower receiving surface, such as a sink or washbasin, to meet the needs of daily hand washing and cleaning. The tap water nozzle 220 is installed on the faucet body 200 directly above the water nozzle 210. The water nozzle 210 and the tap water nozzle 220 are vertically spaced, and the water outlet direction of the tap water nozzle 220 does not fall within the projection range of the water nozzle 210.

[0029] For example, at the horizontal extension end of the faucet body 200, the water outlet nozzle 210 and the tap water nozzle 220 are located on the left and right sides respectively, and the water outlet nozzle 210 and the tap water nozzle 220 are arranged symmetrically or asymmetrically on the same horizontal plane, with their respective water outlet directions pointing towards the receiving areas on the left and right sides, without overlapping or interference. For another example, the water outlet nozzle 210 is installed at the front end of the faucet body 200 extending forward, while the tap water nozzle 220 is installed behind the water outlet nozzle 210. The water outlet nozzle 210 and the tap water nozzle 220 are staggered in the front-back direction, and the installation position and water outlet direction of the tap water nozzle 220 both avoid the projection range of the water outlet nozzle 210.

[0030] Specifically, the fluid distributor 100 is fixedly mounted inside the faucet body 200, and the liquid outlet channel 1111 of the fluid distributor 100 is connected to the water outlet nozzle 210 of the faucet body 200 to achieve smooth output of fluid at the required temperature. In this embodiment, the faucet 1000 also includes a water pipe, which is arranged on one side of the fluid distributor 100, and one end of the water pipe is connected to the water outlet nozzle 220 of the faucet body 200 for supplying direct tap water. Therefore, the internal space of the faucet body 200 can be fully utilized, and the corrosion of the internal channels and components of the fluid distributor 100 by the external environment can be reduced, thus extending the service life of the fluid distributor 100. At the same time, the liquid outlet channel 1111 is connected to the water outlet nozzle 210, and the positions of the tap water nozzle 220 and the water outlet nozzle 210 are staggered. This not only ensures that the temperature-compliant fluid after being screened by the fluid distributor 100 can be directly output independently through the water outlet nozzle 210 to meet the user's needs for the temperature-adjusted fluid, but also effectively avoids mutual interference between two fluids with different uses during the output process. For example, when using the fluid at the water outlet nozzle 210, the presence of the tap water nozzle 220 will not cause the fluid to splash into the usage area, and vice versa, thus improving the convenience and cleanliness during use.

[0031] Furthermore, please combine Figures 1 to 3 As shown, the main body 110 of the distributor includes a detachably connected top seat 114 and a base 115. This detachable connection provides convenience for later maintenance, repair, or cleaning, reducing maintenance costs and operational difficulties. The base 115 is sleeved on the outside of the top seat 114. After assembly, the top seat 114 and the base 115 together form the aforementioned liquid outlet channel 1111, hot water channel 1112, and room temperature water channel 1116. The base 115 is also provided with a pipe clamp 1151, which is located on the outside of the top seat 114 and is used to limit and fix the aforementioned water pipe. The water pipe, the liquid outlet channel 1111, the hot water channel 1112, and the room temperature water channel 1116 are all independently configured structures.

[0032] This configuration, with its independent arrangement of the water inlet pipe and the liquid outlet channel 1111, hot water channel 1112, and ambient temperature water channel 1116, and the pipe clamp 1151 limiting and fixing the water inlet pipe, can, on the one hand, prevent changes in the pressure and flow rate of the fluid in the water inlet pipe from affecting the fluid transport status in the hot water channel 1112, ambient temperature water channel 1116, and liquid outlet channel 1111, ensuring the stability of the output fluid temperature and flow rate. On the other hand, the fixing effect of the pipe clamp 1151 prevents the water inlet pipe from shifting due to slight collisions or vibrations during use, preventing leakage caused by seal failure at pipe connections, and improving the overall structural stability of the faucet 1000.

[0033] It should be noted that the aforementioned return channel 1113 effectively prevents the fluid in the hot water channel 1112 from failing to return, thus preventing the risk of damage to the seals of the hot water channel 1112, fluid leakage, or additional pressure load on the solenoid valve 112 due to increased pressure caused by continuous supply. With the timely drainage of stagnant fluid by the return channel 1113, the pressure in the hot water channel 1112 is effectively balanced, avoiding the risk of structural damage caused by abnormal pressure and ensuring the operational safety of the distributor body 110 and the entire faucet 1000 system. Simultaneously, the returned fluid can be recycled, reducing waste caused by unusable fluid stagnation. Especially in hot water supply scenarios, this reduces energy loss due to cooling of stagnant hot water, meeting the requirements for water and energy conservation. Furthermore, it avoids problems such as deterioration and impurity deposition that may occur when fluid remains stagnant in the hot water channel 1112 for extended periods, ensuring that the fluid delivered to the outlet channel 1111 via the hot water channel 1112 maintains its preset quality after the solenoid valve 112 releases the obstruction, guaranteeing a superior user experience.

[0034] It is worth mentioning that by promptly removing the fluid from the fluid distributor 100 through the return channel 1113, the long-term stress on the connection between the hot water channel 1112 and the solenoid valve 112 caused by pressure buildup is eliminated, reducing wear or aging of components caused by overload, extending the overall service life of the distributor body 110 and related accessories, and reducing the frequency of maintenance and replacement.

[0035] As a preferred embodiment, please refer to... Figures 1 to 3As shown, the return channel 1113, the hot water channel 1112, and the ambient temperature water channel 1116 are all located on the opposite side of the solenoid valve 112 away from the liquid outlet channel 1111. The return channel 1113 and the liquid outlet channel 1111 are coaxially arranged, forming a layout structure with the solenoid valve 112 as the boundary, the two channels are symmetrical and their axes coincide. When the solenoid valve 112 activates its blocking function to cut off the flow of fluid to the outlet channel 1111, the stagnant fluid in the hot water channel 1112, which is continuously transported, can flow directly to the return channel 1113 on the same side. This significantly shortens the fluid return path and avoids pressure buildup caused by the excessively long path in the hot water channel 1112. At the same time, the coaxial arrangement of the return channel 1113 and the outlet channel 1111 allows for a regular arrangement of channels based on the central axis of the solenoid valve 112. This effectively reduces the space occupied inside the distributor body 110, lowers the risk of structural interference caused by the staggered arrangement of channels, and ensures a compact fit between the distributor body 110 and other components of the faucet body 200. Furthermore, the coaxial arrangement ensures that the central axis of the return channel 1113 coincides with that of the outlet channel 1111. During the return process, the fluid can flow stably along the axial direction, reducing the occurrence of local turbulence. This maintains the stability of the fluid pressure in the hot water channel 1112, preventing pressure fluctuations from causing damage to the sealing structure at the connection between the hot water channel 1112 and the return channel 1113, and ensuring the reliability of independent fluid delivery in each hot water channel 1112.

[0036] Understandably, such as Figure 1 As shown, the design of the return channel 1113, hot water channel 1112, and ambient temperature water channel 1116 being located on the same side ensures that the connection path lengths of all hot water channels 1112 and return channel 1113 are consistent, avoiding differences in return efficiency caused by the dispersed channel positions. This ensures that the fluid blocked in all hot water channels 1112 can return efficiently, preventing fluid accumulation in some hot water channels 1112 due to poor return flow. This further maintains the operational stability of the entire fluid distributor 100 and provides a regular structural basis for subsequent channel inspection and maintenance, reducing the difficulty of maintenance caused by the messy internal channel layout of the fluid distributor 100.

[0037] It should be noted that, for details please refer to [link / reference]. Figure 1With the flow direction of the fluid inside the distributor body 110 as a reference, when the solenoid valve 112 is located in the outlet channel 1111, the temperature sensing element 113 is positioned upstream of the solenoid valve 112. This means the fluid must first flow through the detection area of ​​the temperature sensing element 113 before entering the control range of the solenoid valve 112. In this way, real-time temperature data of the fluid in the outlet channel 1111 can be captured before the fluid enters the on / off and flow control stages of the solenoid valve 112. This data can serve as the basis for the solenoid valve 112 to perform its control actions, avoiding inaccurate control due to delayed detection. That is, if the temperature sensing element 113 is located downstream of the solenoid valve 112, and the fluid has already been output through the solenoid valve 112 before temperature detection, even if the temperature deviates from the preset range, it is impossible to intervene in the output fluid with unqualified temperature. However, if the temperature sensing element 113 is located upstream, the solenoid valve 112 can make timely judgments and adjustments based on the temperature signal transmitted by the temperature sensing element 113: when the detected temperature is lower than the preset value, the solenoid valve 112 immediately blocks the fluid with unqualified temperature in the hot water channel 1112 and discharges it through the return channel 1113 until the temperature sensing element 113 detects that the fluid temperature meets the standard, and then opens the hot water channel 1112 to allow the fluid to be output independently; when the detected temperature is higher than the preset value, the solenoid valve 112 also performs the blocking and discharge operation to prevent overheated fluid from entering the outlet channel 1111 for output. Therefore, the temperature sensing element 113 is located upstream of the solenoid valve 112, which can effectively avoid temperature fluctuations caused by asynchronous temperature detection and control, and ensure that the fluid temperature output through the water outlet nozzle 210 always meets the user's requirements.

[0038] Preferably, please refer to the following: Figure 1 As shown, the aforementioned temperature sensing element 113 and solenoid valve 112 are arranged adjacent to each other, which can significantly shorten the path length and time of temperature signal transmission from the detection end to the solenoid valve 112, reduce signal transmission delay, and avoid the solenoid valve 112 failing to respond to temperature changes in a timely manner due to signal lag, thus providing critical time guarantee for the solenoid valve 112 to quickly perform on / off adjustment or flow regulation actions.

[0039] In some embodiments, please combine Figure 2 and Figure 3 As shown, the top seat 114 has a valve chamber 1115 that communicates with the liquid outlet channel 1111, and the detection end of the aforementioned temperature sensing element 113 is embedded inside the valve chamber 1115. At this time, the detection end of the temperature sensing element 113 can directly contact the mixed fluid that is about to enter the liquid outlet channel 1111. At this stage, the fluid has been fully mixed and has not undergone excessive heat exchange with the wall due to flowing a long distance through the channel, thus providing a stable detection environment for the temperature sensing element 113. Therefore, the data detected by the temperature sensing element 113 can accurately reflect the true temperature of the mixed fluid.

[0040] In some embodiments, please refer to Figure 2 The temperature sensing element 113 is positioned at the intersection of several hot water channels 1112 and the liquid outlet channel 1111, meaning it is located on the fluid transport path of the hot water channel 1112. This allows the temperature sensing element 113 to directly contact the fluid transported within the corresponding hot water channel 1112 and accurately acquire the temperature data of the fluid within a single hot water channel 1112, avoiding temperature judgment errors caused by detecting multiple fluid streams. Specifically, the solenoid valve 112 adjusts the on / off state of the corresponding hot water channel 1112 based on the independent temperature data of the fluid within the hot water channel 1112 to achieve accurate selection of fluid temperature. Considering the actual application scenarios of the faucet 1000, whether it's the need for stable warm water temperature during household washing or the strict requirements for specific temperature ranges in industrial auxiliary water use, the temperature sensing position on the hot water channel 1112 allows the temperature sensing element 113 to capture the fluid temperature status immediately. When the temperature deviates from the preset range, it can quickly transmit a signal to the solenoid valve 112, causing the solenoid valve 112 to promptly execute a blocking operation to prevent the independent output of fluid with substandard temperature. This effectively improves the stability and accuracy of the fluid temperature output by the faucet 1000, while reducing fluid waste caused by substandard temperature.

[0041] Preferably, please refer to the following for details. Figure 2 and Figure 3 As shown, a pressure stabilizing channel 1114 is also provided inside the distributor body 110, and several hot water channels 1112 are connected to the liquid outlet channel 1111 through the pressure stabilizing channel 1114. The fluids transported by the several hot water channels 1112 first flow into the pressure stabilizing channel 1114, and then connect to the liquid outlet channel 1111 through the pressure stabilizing channel 1114. At the same time, the detection end of the temperature sensing element 113 extends into the pressure stabilizing channel 1114 and directly contacts the fluid flowing through it.

[0042] With this configuration, the pressure stabilizing channel 1114 can balance the pressure of the fluids transported by the hot water channel 1112 and the ambient temperature water channel 1116, preventing fluctuations in the output fluid flow caused by pressure differences in the water supply units corresponding to the hot water channel 1112 and the ambient temperature water channel 1116. This ensures that the fluid forms a stable and independent flow field in the pressure stabilizing channel 1114 before entering the liquid outlet channel 1111, ensuring that the fluids in the hot water channel 1112 and the ambient temperature water channel 1116 are transported stably according to the preset requirements, and reducing the instability of the output state caused by pressure fluctuations.

[0043] Based on this, the detection end of the temperature sensing element 113 extends into the pressure stabilizing channel 1114, enabling direct detection of the fluid temperature within a single hot water channel 1112. This temperature data better reflects the true temperature state of the fluid, providing a reliable basis for the control of the solenoid valve 112. This avoids interference with the detection results caused by pressure fluctuations leading to changes in fluid flow rate and resulting in local temperature disturbances. This allows the solenoid valve 112 to better match the on / off state and flow rate adjustment of the outlet channel 1111 with actual temperature requirements, thereby effectively reducing temperature fluctuations caused by pressure fluctuations. This improves the stability and control accuracy of the fluid temperature output by the faucet 1000. At the same time, stable delivery status and pressure also reduce energy consumption and losses during fluid delivery, enhancing the adaptability of the device under different water source pressure conditions.

[0044] It should be further explained that both of the above-mentioned temperature sensing element 113 detection end setting methods can ensure that the temperature sensing element 113 obtains a high-quality temperature signal, so that the solenoid valve 112 can accurately adjust the fluid output state of the liquid outlet channel 1111 based on the signal. For example, when the temperature is lower than the preset value, the flow rate can be increased, and when the temperature is higher than the preset value, the flow rate can be reduced or the flow can be interrupted briefly, effectively suppressing the temperature fluctuation of the fluid. At the same time, with the temperature sensing element 113 and the solenoid valve 112 set up close to each other, the independent delivery of hot water channel 1112, and the pressure balance of pressure stabilizing channel 1114, it can not only meet the water temperature comfort requirements of washing and cleaning in daily life scenarios, but also adapt to the strict requirements of fluid temperature accuracy in industrial scenarios, avoid the decline in user experience or interference with production processes due to temperature runaway, and reduce the waste of fluid and energy caused by improper temperature control, further enhancing the overall performance and energy-saving characteristics of the faucet.

[0045] As a preferred embodiment, please refer to the following for details. Figure 1 , Figure 2 as well as Figure 3As shown, the central axes of the hot water channel 1112 and the ambient temperature water channel 1116 are arranged in parallel, which ensures that all pipe interfaces forming through the distributor body 110 are located on the same side of the distributor body 110. This not only facilitates the connection and assembly of the distributor body 110 with the external water supply pipes, but also reduces the spatial cross-entanglement of connecting pipes due to the concentrated location of each pipe interface, making the pipeline layout more regular and reducing installation interference caused by pipe intersections. It also simplifies the installation process and improves assembly efficiency. Furthermore, it facilitates subsequent inspection and maintenance of the connection between the hot water channel 1112 and the external pipes, eliminating the need to operate on different sides of the distributor body 110, reducing space constraints during maintenance, and improving maintenance convenience. In addition, the parallel central axis design allows for a more compact and orderly arrangement of the hot water channel 1112 inside the distributor body 110. This design enables a multi-channel layout within a limited space, helping to reduce the overall size of the distributor body 110 and making it easier to adapt to the internal installation space of faucet bodies 200 of different specifications, thus enhancing the versatility of the device. At the same time, the parallel hot water channel 1112 and the ambient temperature water channel 1116 can reduce turbulence caused by sudden changes in direction when the fluid flows in the hot water channel 1112, reduce local pressure loss, and make the fluid transport state in the hot water channel 1112 and the ambient temperature water channel 1116 more stable, avoiding flow fluctuations caused by flow turbulence, thereby ensuring the accuracy of temperature detection by the temperature sensing element 113 and providing a basis for the precise control of the solenoid valve 112.

[0046] As a preferred embodiment, please refer to the following for details. Figure 5 A snap-fit ​​protrusion 1161 is provided on the top seat 114, and a corresponding limiting slot 1162 adapted to the structure of the snap-fit ​​protrusion 1161 is provided on the base 115. When the top seat 114 and the base 115 are assembled, the snap-fit ​​protrusion 1161 can align with the limiting slot 1162 and complete the fastening. Thus, the snap-fit ​​between the snap-fit ​​protrusion 1161 and the limiting slot 1162 achieves the purpose of quickly fixing the top seat 114 and the base 115. In other embodiments, the snap-fit ​​protrusion 1161 can also be provided on the base 115, and the top seat 114 will have a corresponding limiting slot 1162 adapted to the structure of the snap-fit ​​protrusion 1161, which can also achieve the alignment and fastening of the snap-fit ​​protrusion 1161 and the limiting slot 1162.

[0047] Compared to bolt connections and welding, the snap-fit ​​protrusion 1161 and the limiting slot 1162 can be engaged without the need for additional tools. The top seat 114 and the base 115 can be fixed by simply pressing and aligning them manually. This significantly improves the assembly efficiency of the distributor body 110 and reduces the technical requirements for assembly operations, making it more suitable for the batch assembly needs in the faucet production process. Understandably, the engagement of the buckle protrusion 1161 and the limiting slot 1162 ensures the structural stability of the top seat 114 and the base 115 after assembly. In other words, the mechanical constraint formed by the buckle protrusion 1161 and the limiting slot 1162 in the engaged state can effectively resist the tendency of the connection to loosen due to fluid impact and slight external vibration during the use of the distributor body 110. This ensures that the top seat 114 and the base 115 always maintain a relatively fixed positional relationship, thereby ensuring that the internal preset hot water channel 1112, liquid outlet channel 1111, pressure stabilizing channel 1114 and other flow channels can be accurately aligned. This avoids problems such as fluid leakage and poor delivery caused by misalignment of flow channels, and provides a structural basis for the stable flow and independent delivery of fluid in the distributor body 110.

[0048] In addition, the snap-fit ​​connection also facilitates subsequent maintenance of the distributor body 110. When it is necessary to clean the hot water channel 1112, liquid outlet channel 1111, pressure stabilizing channel 1114, or to repair or replace components such as temperature measuring element 113 and solenoid valve 112, the top seat 114 and base 115 can be disassembled simply by using external force to separate the snap-fit ​​protrusion 1161 from the limit latch 1162. This does not require damaging the overall structure, reducing maintenance difficulty and cost, while also reducing the downtime of the device due to maintenance, ensuring the continuous and stable use of the faucet.

[0049] It is worth mentioning that, by engaging the snap-fit ​​protrusion 1161 with the limiting slot 1162, an effective circumferential limiting effect is provided during the rotational assembly of the distributor body 110 into the faucet body 200. When the distributor body 110 rotates around a preset axis to complete the assembly with the faucet body 200, the tight engagement of the snap-fit ​​protrusion 1161 and the limiting slot 1162 restricts relative rotation between the top seat 114 and the base 115, preventing circumferential misalignment of the top seat 114 and the base 115 due to assembly torque during rotational assembly. It also ensures that the assembly positioning parts on the outside of the distributor body 110 are precisely aligned with the corresponding assembly structure of the faucet body 200, preventing misalignment due to relative rotation of the top seat 114 and the base 115. The overall assembly posture of the distributor body 110 is offset to avoid misalignment problems such as jamming and misalignment of interfaces during the assembly process, ensuring the smoothness of the rotary assembly. At the same time, it ensures that the internal flow channels of the distributor body 110, such as the liquid outlet channel 1111, hot water channel 1112, and normal temperature water channel 1116, can be accurately connected to the corresponding pipelines of the faucet body 200 after assembly. This provides structural protection for the stable delivery of fluid and the normal operation of the subsequent temperature control system, reduces rework and adjustment caused by assembly misalignment, and improves the overall assembly efficiency.

[0050] Furthermore, please refer to the specific details. Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the snap-fit ​​protrusion 1161 is integrally formed on the outer peripheral wall of the top seat 114 and extends in segments along the circumferential direction of the top seat 114. The extension length of the snap-fit ​​protrusion 1161 must be compatible with the circumferential dimension of the upper limit latch 1162 of the base 115 to ensure that the snap-fit ​​protrusion 1161 and the limit latch 1162 can form a sufficient contact area when they are engaged, avoiding local loosening after engagement due to insufficient contact length. The extension direction of the snap-fit ​​protrusion 1161 is consistent with the circumferential extension of the top seat 114, and the engagement strength will not be weakened due to excessive extension, thus achieving effective constraint within the axial range where the top seat 114 and the base 115 meet.

[0051] It should be noted that the number of snap-fit ​​protrusions 1161 needs to be set in conjunction with the overall dimensions of the top seat 114, the expected assembly stress, and the requirements for snap-fit ​​stability. It can be two, three, four, five, etc. Each snap-fit ​​protrusion 1161 is evenly distributed around the axis of the top seat 114 along its circumference. This ensures that when the top seat 114 is snapped into the base 115, each snap-fit ​​protrusion 1161 can simultaneously align and snap into the corresponding limiting slot 1162 on the base 115. This avoids snap-fit ​​deviations or localized stress concentrations caused by uneven distribution, where some snap-fit ​​protrusions 1161 contact first and others later. Meanwhile, multiple evenly distributed snap-fit ​​protrusions 1161 can evenly distribute the assembly stress between the top seat 114 and the base 115 to each snap-fit ​​point, preventing a single snap-fit ​​protrusion 1161 from undergoing plastic deformation due to excessive force, effectively improving the overall load-bearing capacity of the connection structure between the top seat 114 and the base 115. Especially when the distributor body 110 is subjected to fluid impact or external vibration, it can maintain connection stability through multiple points of uniform force, further ensuring the precise alignment of the internal flow channels of the top seat 114 and the base 115.

[0052] Specifically, please combine Figure 2 , Figure 3 and Figure 5 As shown, the top seat 114 includes an integrally connected main body 1141 and a plurality of branch portions 1142, which can eliminate the connection gap between the branch portions 1142 and the main body 1141 and reduce the risk of fluid leakage at the connection. The main body 1141 has a main channel cavity 1111a and a main outlet 1111b corresponding to the main channel cavity 1111a. The main outlet 1111b is connected to the main channel cavity 1111a. The main channel cavity 1111a and the main outlet 1111b constitute the aforementioned liquid outlet channel 1111, which is used to receive and transport independently output fluid. Each branch 1142 has a branch flow channel cavity 1112a. The branch flow channel cavity 1112a of each branch 1142 constitutes a part of the corresponding hot water channel 1112. All branch flow channel cavities 1112a of the branch 1142 are internally connected to the main channel cavity 1111a of the main body 1141, ensuring that the fluid of the hot water channel 1112 and the normal temperature water channel 1116 can flow into the main channel cavity 1111a through the branch flow channel cavity 1112a.

[0053] The base 115, which is adapted to the top seat 114, includes a bottom wall 1152 and a sleeve wall 1153. The sleeve wall 1153 is integrally formed on one side of the bottom wall 1152 and protrudes in a direction away from the bottom wall 1152. The bottom wall 1152 has branch openings 1112b that correspond one-to-one with the branch flow channel cavities 1112a of each branch 1142. The branch openings 1112b are connected to the branch flow channel cavities 1112a. Each branch opening 1112b constitutes another part of the corresponding hot water channel 1112, ensuring the complete connection of the hot water channel 1112 and preventing problems such as fluid stagnation and increased transport resistance caused by interruption or misalignment of the hot water channel 1112. This lays the foundation for the stable flow of fluid in the distributor body 110.

[0054] Further, please refer to Figure 1 and Figure 5 In the assembled state, the sleeve wall 1153 of the base 115 can form an abutment fit with the outer peripheral side of the top seat 114. The abutment coverage of the sleeve wall 1153 covers at least part of the outer peripheral side of the main body 1141 and the outer peripheral side of all branches 1142. Therefore, during the assembly stage, it will provide radial positioning constraints for the top seat 114 and the base 115, avoiding circumferential offset or axial misalignment between the two during the assembly process. This ensures that the flow channel of the top seat 114 and the opening of the base 115 always maintain precise alignment, thereby preventing the flow channel from being misaligned. The misalignment causes fluid leakage. At the same time, the sleeve wall 1153 covering the peripheral side of the top seat 114 can also enhance the overall structural strength of the top seat 114 and the base 115 after assembly, resist the radial pressure generated when the fluid flows in the flow channel, and prevent the branch part 1142 or the main body part 1141 from changing the cross-sectional area of ​​the flow channel due to stress deformation, thus ensuring stable fluid flow. After assembly, each branch port 1112b in the bottom wall 1152 is also sealed and connected to the branch flow channel cavity 1112a of the corresponding branch part 1142.

[0055] It is worth mentioning that the abutting fit between the sleeve wall 1153 of the base 115 and the outer periphery of the top seat 114 can, to a certain extent, prevent external impurities from entering the interior of the distributor body 110, thus avoiding impurities from clogging the flow channel and affecting the stability of fluid delivery. At the same time, the compact assembly of the top seat 114 and the base 115 through the sleeve wall 1153 can reduce the overall volume of the distributor body 110, making it easier for the distributor body 110 to be smoothly embedded into the faucet body 200 and better fit the compact space inside the faucet body 200.

[0056] In this embodiment, please refer to the following for details. Figures 1 to 7As shown, the top seat 114 also includes a return flow section 1144. The return flow section 1144 and the main body 1141 of the top seat 114 are formed by an integral molding process, which can completely eliminate the assembly gap that may be caused by the separate connection, avoid fluid leakage from the connection gap during the return flow process, and reduce the risk of impurities entering the return flow channel 1113 through the gap and blocking the flow channel, ensuring that the return flow path is always unobstructed, and providing a structural basis for subsequent fluid drainage. The return flow section 1144 has a return flow cavity 1113a inside, and the central axis of the return flow cavity 1113a is collinear with the central axis of the main flow cavity 1111a in the main body 1141, ensuring that the return flow cavity 1113a and the main flow cavity 1111a are coaxially distributed in the axial direction. Meanwhile, the base 115 has a return port 1113b that matches the position and size of the return channel cavity 1113a. After the top seat 114 and the base 115 are assembled, the return channel cavity 1113a of the return part 1144 and the return port 1113b of the base 115 are sealed and connected. The return channel cavity 1113a and the return port 1113b together form a complete return channel 1113 inside the distributor body 110, providing a dedicated path for fluid return. This allows the fluid in the hot water channel 1112, which is blocked by the solenoid valve 112, to enter the return channel cavity 1113a through the branch channel cavity 1112a and the main channel cavity 1111a, and then smoothly return through the return port 1113b of the base 115, avoiding long-term stagnation of fluid in the hot water channel 1112.

[0057] In the above, the return channel cavity 1113a and the main channel cavity 1111a are arranged with their central axes collinear, which can make the flow direction of the return fluid consistent with the flow direction of the liquid outlet fluid in the main channel cavity 1111a in the axial direction. This reduces the mutual interference between the return fluid and the liquid outlet fluid in the flow field caused by the offset of the axis of the return channel cavity 1113a and the axis of the main channel cavity 1111a. It also avoids the flow field disturbance causing fluctuations in the fluid delivery pressure or abnormal delivery status of the hot water channel 1112, and provides a prerequisite for the temperature sensing element 113 to obtain accurate single-channel fluid temperature data, thereby assisting the solenoid valve 112 to perform temperature control based on accurate data. In addition, the fluid stagnating in the hot water channel 1112 can be promptly cleared, preventing the fluid from experiencing temperature deviation due to heat exchange with the wall of the hot water channel 1112. This ensures that the fluid subsequently delivered independently into the main channel cavity 1111a is fresh fluid that meets the initial supply temperature, reducing temperature fluctuations in the output fluid. This allows the solenoid valve 112 to better regulate the liquid outlet channel 1111, making it more aligned with the preset temperature target, ultimately improving the stability of the faucet's output fluid temperature. Of course, the smooth return of fluid can also reduce fluid waste caused by stagnation, lowering water and energy consumption.

[0058] As a preferred embodiment, please refer to the following for details. Figure 7As shown, the bottom wall 1152 is flush with the peripheral side of the top seat 114. A portion of the bottom wall 1152 protrudes outward and extends beyond the peripheral side of the top seat 114 to form a pipe clamp 1151 for fixing a water pipe. Simultaneously, a clamp groove 1154 is provided on the pipe clamp 1151. The opening direction of the clamp groove 1154 is radially arranged along the bottom wall 1152, allowing the clamp groove 1154 to provide embedding space for the water pipe from the radial direction of the bottom wall 1152. This allows the water pipe to be directly embedded into the clamp groove 1154 from the radial direction of the bottom wall 1152 without axial insertion, thus fitting a faucet. The limited and compact space inside the main body 200 significantly reduces the difficulty of installing the water pipe; and the embedded water pipe is constrained radially and circumferentially by the groove wall of the clamping groove 1154, which can effectively limit the positional displacement of the water pipe due to water flow impact, slight external contact or deformation after long-term use, and prevent the water pipe from accidentally contacting or squeezing the hot water channel 1112 and liquid outlet channel 1111 of the distributor body 110, ensuring that the independent operation of the water pipe and each channel is not disturbed, thereby ensuring the stability of the water pipe delivering fluid to the water nozzle 220.

[0059] Furthermore, the bottom wall 1152 directly protrudes to form the pipe clamp 1151, eliminating the need for additional independent fixing components on the distributor body 110. This simplifies the overall structure of the distributor body 110, reduces the number of components, lowers manufacturing costs, and reduces the overall size of the distributor body 110, making it easier to adapt to the internal installation space of faucet bodies 200 of different specifications. In addition, the radially open clamp groove 1154 provides convenience for subsequent inspection and replacement of the water pipe. When the water pipe needs maintenance, it can be removed radially without disassembling the core connection structure between the distributor body 110 and the faucet body 200. This reduces the complexity and time required for maintenance, while also preventing accidental damage to the internal flow channels or critical components such as the temperature sensing element 113 and solenoid valve 112 of the distributor body 110 during maintenance. This ensures the continuous stability of the temperature control function of the fluid distributor 100, ultimately ensuring the reliability of the overall performance of the faucet.

[0060] Further details are available according to... Figure 6As shown, the top seat 114 also includes a connecting portion 1143. The connecting portion 1143 is disposed between two adjacent branch portions 1142, or it can be disposed between the main body 1141 and the branch portion 1142. Of course, connecting portions 1143 are provided between two adjacent branch portions 1142 and between the main body 1141 and the branch portion 1142. The connecting portion 1143 and the main body 1141 and the branch portion 1142 of the top seat 114 are manufactured using an integral molding process to form a continuous structural whole. A connecting hole is opened on the side of the connecting portion 1143 near the bottom wall 1152 of the base 115. The bottom wall 1152 of the base 115 is connected by fasteners (such as bolts and screws that fit the connecting hole). (Hacks, etc.) are inserted and fastened to the connecting hole to achieve a fixed connection between the top seat 114 and the base 115; at the same time, a recessed space 1155 is formed on the sleeve wall 1153 of the base 115. The shape and size of the recessed space 1155 are completely adapted to the shape of the connecting part 1143. During the assembly of the top seat 114 and the base 115, the connecting part 1143 can be embedded in the recessed space 1155, so that the connecting part 1143 and the sleeve wall 1153 form a tight positioning fit.

[0061] Understandably, the connection points between the main body 1141 and the branch 1142 of the top seat 114, as well as the connection points between adjacent branch 1142, are typically weak areas of the top seat 114 that bear fluid pressure. Specifically, the main body 1141 must bear the pressure of the independently transported fluid within the main flow channel 1111a, and the branch 1142 must bear the pressure of the fluid within the branch flow channel 1112a. During long-term use, these connection points are prone to deformation or cracking due to pressure impact. The connecting part 1143 effectively fills the structural gaps and increases the structural thickness of the connection points, effectively improving the deformation resistance of the top seat 114. This prevents damage to the structural integrity of the branch flow channel 1112a and the main flow channel 1111a due to branch 1142 offset or cracking of the connection points, thereby ensuring that the fluid in the hot water channel 1112 and the ambient temperature water channel 1116 is transported to the main flow channel 1111a for independent output along a preset path, preventing flow fluctuations caused by changes in the cross-sectional area of ​​the flow channels.

[0062] Secondly, the bottom wall 1152, through the fixed fit between the fastener and the connecting hole of the connecting part 1143, further enhances the connection strength between the top seat 114 and the base 115. It can effectively resist the assembly torque generated when the distributor body 110 is rotated and assembled in the faucet body 200, or the vibration caused by the operation of the faucet switch during use. It avoids relative axial displacement or circumferential offset between the top seat 114 and the base 115, ensuring that the branch flow channel cavity 1112a of the top seat 114 and the branch port 1112b of the base 115, and the main flow channel cavity 1111a of the top seat 114 and the main port 1111b of the base 115 always remain sealed and connected, preventing fluid leakage caused by flow channel misalignment, and ensuring the sealing and smoothness of fluid transportation.

[0063] Furthermore, the fitting space 1155 of the sleeve wall 1153 and the fitting of the connecting part 1143 can play a pre-positioning and guiding role during the assembly stage. Specifically, when the top seat 114 and the base 115 are mated, the process of the connecting part 1143 inserting into the fitting space 1155 can automatically correct the alignment deviation between the top seat 114 and the base 115, achieving fast and accurate assembly without repeated manual adjustments, significantly improving assembly efficiency; at the same time, the fitting can form a dual radial and circumferential limit on the connecting part 1143, further restricting the relative movement of the top seat 114 and the base 115, especially when the distributor body 110 is rotated into the faucet body 200, it can prevent the top seat 1143 from being damaged by the rotation of the connecting part 1153. 4. The relative offset between the distributor body 110 and the base 115 causes the overall assembly posture of the distributor body 110 to be abnormal. This ensures that the external assembly structure of the distributor body 110 is precisely connected with the internal structure of the faucet body 200, reducing assembly jamming or pipe misalignment. It also ensures that after assembly, the liquid outlet channel 1111 of the distributor body 110 can be smoothly connected to the water outlet nozzle 210 of the faucet body 200, and the hot water channel 1112 can be smoothly connected to the external water supply unit. Ultimately, this provides comprehensive structural support for the overall fluid delivery stability and temperature control accuracy of the faucet.
