Technical Field
[0001] This utility model relates to the technical field of automated temperature control systems for faucets, and more particularly to an intelligent thermostatic control module, which is especially suitable for supplying water to washbasins. Background Technology
[0002] Currently, smart faucets suffer from poor stability in achieving intelligent functionality, failing to effectively integrate smart technology with user experience and neglecting ease of use and stability. For example, a Chinese invention patent application with application number CN202210152317.1 (publication number CN114484009A) discloses a swing-open mixing valve core capable of intelligent control, comprising a valve body and a main control board. The valve body contains a valve core for controlling water temperature and flow rate. The valve body also contains an execution unit 1 and an execution unit 2, as well as a detection unit 1 for detecting water temperature and a detection unit 2 for detecting water pressure. The main control board receives signals from the detection unit 1 and drives the valve core through the execution unit 1 to control the water flow rate, and receives signals from the detection unit 2 and drives the valve core through the execution unit 2 to control the water temperature. Because most users experience significant fluctuations in hot water pressure or temperature, the valve core needs to rotate continuously to adjust the temperature. The valve core's response is not quick enough to handle water pressure fluctuations. Due to the pressure difference, the range of water flow fluctuations increases, and the water temperature fluctuates between hot and cold for a period of time, affecting the user experience.
[0003] Therefore, the applicant has applied for and filed a Chinese utility model patent with patent number CN202420856672.1 (publication number CN222229538U), disclosing a thermostat for controlling water temperature. The thermostat includes a valve seat having a cold water inlet channel, a hot water inlet channel, a first valve core mounting cavity, a second valve core mounting cavity, a cold water outlet channel, a hot water outlet channel, a mixing chamber, a third valve core mounting cavity, and a mixed water outlet channel. The mixing chamber is connected to the mixed water outlet channel. A first flow regulating valve core is installed in the first valve core mounting cavity. The cold water inlet channel is connected to the first inlet end of the first flow regulating valve core, and the first outlet end of the first flow regulating valve core is connected to... The cold water outlet channel is connected, and the first moving valve plate of the first flow regulating valve core is driven to rotate by the first motor to regulate the cold water flow. The second flow regulating valve core is installed in the second valve core mounting cavity. The hot water inlet channel is connected to the second inlet end of the second flow regulating valve core, and the second outlet end of the second flow regulating valve core is connected to the hot water outlet channel. The second moving valve plate of the second flow regulating valve core is driven to rotate by the second motor to regulate the hot water flow. The balancing valve core is installed in the third valve core mounting cavity. The cold water outlet channel is connected to the cold water inlet of the balancing valve core, and the hot water outlet channel is connected to the hot water inlet of the balancing valve core. Both the cold water outlet and the hot water outlet of the balancing valve core are connected to the mixing chamber.
[0004] However, the aforementioned balancing valve core is located at the outlet, while unstable water pressure is generally reflected at the inlet. This means that unstable water pressure requires the first motor of the first flow regulating valve core and the second motor of the second flow regulating valve core to respond quickly, otherwise, fluctuations in the outlet water temperature will occur. In other words, the first motor, the second motor, and the balancing valve core need to respond simultaneously, which places extremely high demands on the program control. Therefore, in actual use, the user experience is still not very good. Furthermore, its temperature control module, balancing module, water distribution module, and emergency start / stop are all integrated into a single housing, making housing manufacturing difficult. If the customer only needs a few modules, the entire thermostat must be replaced, as it cannot be modularly disassembled and selectively used. Moreover, the aforementioned controller cannot adjust the water flow rate.
[0005] Therefore, the existing automatic temperature control modules for faucets still need further improvement. Summary of the Invention
[0006] The technical problem to be solved by this utility model is to provide an intelligent water temperature control module with a reasonable structure, less affected by fluctuations in inlet water pressure, multiple modules and independent control of each module, in light of the current state of the technology. Each module in this module exists and is controlled independently, which greatly simplifies the control method, greatly reduces the control difficulty and manufacturing difficulty, and greatly improves the control accuracy of water output and water temperature. Furthermore, they can be selected and combined for use.
[0007] The first technical solution adopted by this utility model to solve the above-mentioned technical problems is: an intelligent water temperature control module, characterized in that: it includes a flow regulation module, a pressure balancing module, and a temperature adjustment module connected in sequence; the flow regulation module includes a first valve seat, the first valve seat having a first cold water inlet channel, a first hot water inlet channel, a flow valve core mounting cavity, a first cold water outlet channel, and a first hot water outlet channel, the flow valve core mounting cavity being provided with a flow regulating valve core controlled by a first motor, the flow regulating valve core being able to adjust the outflow rate of the first cold water outlet channel and the first hot water outlet channel; the pressure balancing module includes a second valve seat, the second valve seat having a second cold water inlet channel, a second hot water inlet channel, and a balance valve core mounting cavity. The system includes a heating chamber, a second cold water outlet channel, and a second hot water outlet channel. A balance valve core is installed in the heating chamber. The temperature control module includes a third valve seat, which has a third cold water inlet channel, a third hot water inlet channel, a temperature control valve core installation chamber, a mixing chamber, and a mixed water outlet channel. The temperature control valve core installation chamber is equipped with a temperature control valve core controlled by a second motor. The temperature control valve core can adjust the mixing ratio of cold water and hot water flowing into the mixing chamber. The mixing chamber is connected to the mixed water outlet channel. The first cold water outlet channel, the second cold water inlet channel, the second cold water outlet channel, and the third cold water inlet channel can be connected sequentially. The first hot water outlet channel, the second hot water inlet channel, the second hot water outlet channel, and the third hot water inlet channel can also be connected sequentially.
[0008] As a method of sequentially connecting modules, the first valve seat and the second valve seat are connected via a water pipe; the second valve seat and the third valve seat are also connected via a water pipe. This method allows for greater spacing between modules, reduces assembly space requirements, and improves assembly flexibility.
[0009] As another method of sequentially connecting the modules, the first and second valve seats are interlocked, connecting the first cold water outlet channel to the second cold water inlet channel, and the first hot water outlet channel to the second hot water inlet channel; the second and third valve seats are interlocked, connecting the second cold water outlet channel to the third cold water inlet channel, and the second hot water outlet channel to the third hot water inlet channel. The advantages of this method are convenient installation and greater integration.
[0010] As a preferred structure of the flow control module, there are two flow control valve core mounting cavities, and two flow control valve cores, with one flow control valve core installed in each flow control valve core mounting cavity; the first cold water inlet channel is connected to the inlet end of one of the flow control valve cores, and the outlet end of the flow control valve core is connected to the first cold water outlet channel; the moving valve plate of the flow control valve core is driven to rotate by a first motor to adjust the flow rate of cold water flowing out of the first cold water outlet channel; the first hot water inlet channel is connected to the inlet end of the other flow control valve core, and the outlet end of the flow control valve core is connected to the first hot water outlet channel; the moving valve plate of the flow control valve core is driven to rotate by a first motor to adjust the flow rate of hot water flowing out of the first hot water outlet channel.
[0011] This method uses a dual-valve core structure to achieve flow regulation. Because there are two motors to adjust and control the corresponding flow regulation valve cores, the overall flow regulation control is simpler, the program requirements are lower, and the adjustment is more precise. It is only necessary to synchronously increase or decrease the outflow of the first cold water outlet channel and the first hot water outlet channel. Moreover, the valve plate assembly of a single flow regulation valve core is also simpler, and the most traditional flow regulation valve plate assembly can be used.
[0012] Alternatively, the moving valve plates of the two flow control valve cores can each be driven to rotate by one of the first motors. This scheme is advantageous for independent control, but its disadvantage is high cost. Alternatively, the moving valve plates of the two flow control valve cores can be driven to rotate by the same first motor. This scheme has the advantage of low cost, but requires relatively higher control precision.
[0013] As another preferred structure for the flow control module, there is only one flow control valve core mounting cavity and one flow control valve core. The first cold water inlet channel is connected to the cold water inlet end of the flow control valve core, and the cold water outlet end of the flow control valve core is connected to the first cold water outlet channel. The first hot water inlet channel is connected to the hot water inlet end of the flow control valve core, and the hot water outlet end of the flow control valve core is connected to the first hot water outlet channel. The moving valve plate of the flow control valve core is driven to rotate by the first motor to adjust the flow rate of the first cold water outlet channel and the first hot water outlet channel.
[0014] This method uses a single valve core for flow regulation, which is less expensive and more compact than using two motor-driven flow regulation valve cores.
[0015] As a preferred structure of the temperature control module, the above-mentioned temperature control valve core mounting cavity has two chambers, and there are two temperature control valve cores. One temperature control valve core is installed in each chamber. The third cold water inlet channel is connected to the inlet end of one of the temperature control valve cores, and the outlet end of the temperature control valve core is connected to the mixing chamber. The moving valve plate of the temperature control valve core is driven to rotate by the second motor to adjust the flow rate of cold water flowing into the mixing chamber. The third hot water inlet channel is connected to the inlet end of the other temperature control valve core, and the outlet end of the temperature control valve core is connected to the mixing chamber. The moving valve plate of the temperature control valve core is driven to rotate by the second motor to adjust the flow rate of hot water flowing into the mixing chamber.
[0016] This method uses a dual-valve core structure to adjust the water temperature. Because there are two motors that control the ratio of hot and cold water to the corresponding temperature-adjusting valve cores, the overall control of water temperature adjustment is simpler, the program requirements are lower, and the adjustment is more precise. Water temperature adjustment can be completed simply by adjusting the flow rates of cold and hot water flowing into the mixing chamber. In addition, the valve plate assembly of a single temperature-adjusting valve core is also simpler, using the most traditional adjustable flow valve plate assembly.
[0017] Alternatively, the moving valve plates of the two temperature-regulating valve cores are each driven to rotate by a second motor. This scheme is advantageous for independent control, but its disadvantage is high cost. Alternatively, the moving valve plates of the two temperature-regulating valve cores are driven to rotate by the same second motor. This scheme has the advantage of low cost, but requires relatively high control precision. As another preferred structure for the temperature-regulating module, there is only one temperature-regulating valve core mounting cavity and one temperature-regulating valve core. The third cold water inlet channel is connected to the cold water inlet end of the temperature-regulating valve core, the third hot water inlet channel is connected to the hot water inlet end of the temperature-regulating valve core, and the mixing outlet end of the temperature-regulating valve core is connected to the mixing chamber. The moving valve plate of the temperature-regulating valve core is driven to rotate by the second motor to adjust the mixing ratio of cold and hot water.
[0018] This method uses a single valve core structure to achieve temperature regulation. Specifically, this temperature regulation valve core is a swing-out mixing valve core, which is the valve core structure of existing household temperature-regulating faucets. The only difference is that the driving method is motor-driven, and the specific valve plate assembly is the existing temperature-regulating valve plate assembly structure. Compared with the aforementioned method of using a dual valve core structure to achieve water temperature regulation, it has lower cost and a more compact structure.
[0019] As a preferred structure of the balancing valve core, the balancing valve core includes a valve housing and a balancing member located inside the valve housing that can slide laterally. The balancing member has a first inlet that connects the second cold water inlet channel to the second cold water outlet channel, and a second inlet that connects the second hot water inlet channel to the second hot water outlet channel. The lateral sliding of the balancing member can change the degree of overlap between the first inlet and the second cold water inlet channel, and change the degree of overlap between the second inlet and the second hot water inlet channel.
[0020] Under water pressure, the lateral sliding of the balancing element automatically adjusts the water flow distribution per unit time in the second cold water outlet channel and the second hot water outlet channel. The balancing element of this pressure balancing valve core adjusts the resistance coefficient of the fluid passing through the valve based on the water pressure of the cold and hot water on both sides, thereby regulating the flow distribution of cold and hot water on both sides. Specifically, when the water pressure on one side of the balancing element increases, the balancing element moves laterally under the water pressure, causing the opening of one side of the pressure balancing valve core to decrease, resulting in a smaller flow rate of fluid entering that side; conversely, the opening on the other side increases, resulting in a larger flow rate of fluid entering that side. This ensures a stable flow rate on both sides of the pressure balancing valve core, preventing sudden changes in the temperature of the fluid flowing out of the inlet pressure balancing device and guaranteeing a good user experience.
[0021] As an improvement, a water flow generator is also installed inside the mixing chamber. A water flow generator is a structure that uses water flow to generate electricity; this is existing technology. In this solution, the water flow generator is placed inside the mixing chamber, and the water flowing in from both sides jointly drives the impeller of the water flow generator to rotate, resulting in higher power generation efficiency. The electrical energy generated by the water flow generator can supply the display screen, or it can supply the battery or other electrical components.
[0022] To further improve the automatic adjustment of the outlet water temperature quickly and accurately, a mixing water temperature sensor is also included. The sensor's sensing head extends into the mixed water outlet channel. The temperature signal of the mixed water measured by the mixing water temperature sensor is compared with the set temperature. The information control module sends a final signal to the two motor control modules, and the moving valve plate of the flow regulating valve core can quickly rotate to the correct angle. Due to its very fast response speed, the problem of fluctuating temperatures in the mixed water outlet will be significantly improved.
[0023] Further improvements include cold water temperature sensors and hot water temperature sensors. The sensing head of the cold water temperature sensor extends into the third cold water inlet channel, and the sensing head of the hot water temperature sensor extends into the third hot water inlet channel. The two temperature sensors measure the temperatures of the cold and hot water respectively, and send the detected water temperature data to the information control module. The information control module, based on a model (which clearly defines the flow rates of hot and cold water to be mixed, thus obtaining the corresponding flow rate and temperature of the mixed water), roughly determines the required rotation angle range of the moving valve plate of the temperature control valve core to ensure the mixed water reaches the set temperature and flow rate. At this point, the moving valve plate of the temperature control valve core will rotate to a certain angle in advance, which is already close to the final required rotation angle to the set temperature.
[0024] To ensure a rational layout of the flow channels, the first cold water inlet channel and the first hot water inlet channel are arranged horizontally and coaxially as the preferred configuration. This facilitates the connection of the cold water inlet pipe, hot water inlet pipe, and outlet pipe to this module. All pipe connections are made from bottom to top, making pipework more convenient and efficient. Furthermore, one flow valve core mounting cavity and the first cold water outlet channel are arranged vertically and coaxially, as are the other flow valve core mounting cavity and the first hot water outlet channel. This vertically continuous arrangement facilitates product molding and makes core extraction during manufacturing easier.
[0025] To facilitate the assembly of the production equipment and valve core, the second valve seat is formed by the mating of the upper valve seat and the lower valve seat. The second cold water inlet channel and the second hot water inlet channel are located on the lower valve seat, while the balance valve core mounting cavity, the second cold water outlet channel and the second hot water outlet channel are located on the upper valve seat.
[0026] The second technical solution adopted by this utility model to solve the above-mentioned technical problems is: an intelligent water temperature control module, characterized in that: it includes a pressure balancing module, a flow regulation module, and a temperature adjustment module connected in sequence; the flow regulation module includes a first valve seat, the first valve seat having a first cold water inlet channel, a first hot water inlet channel, a flow valve core mounting cavity, a first cold water outlet channel, and a first hot water outlet channel, the flow valve core mounting cavity being provided with a flow regulating valve core controlled by a first motor, the flow regulating valve core being able to adjust the outflow rate of the first cold water outlet channel and the first hot water outlet channel; the pressure balancing module includes a second valve seat, the second valve seat having a second cold water inlet channel, a second hot water inlet channel, and a balancing valve core mounting cavity. The system includes a second cold water outlet channel and a second hot water outlet channel. A balance valve core is installed in the balance valve core mounting cavity. The temperature control module includes a third valve seat, which has a third cold water inlet channel, a third hot water inlet channel, a temperature control valve core mounting cavity, a mixing chamber, and a mixed water outlet channel. A temperature control valve core controlled by a second motor is installed in the temperature control valve core mounting cavity. The temperature control valve core can adjust the mixing ratio of cold water and hot water flowing into the mixing chamber. The mixing chamber is connected to the mixed water outlet channel. The second cold water outlet channel, the first cold water inlet channel, the first cold water outlet channel, and the third cold water inlet channel can be connected sequentially. The second hot water outlet channel is connected to the first cold water inlet channel through a water pipe, and the first hot water outlet channel is connected to the third hot water inlet channel through a water pipe.
[0027] To achieve automatic water distribution, an improvement is made by including a diversion module. This module includes a fourth valve seat with a mixing water inlet channel, a diversion valve core mounting cavity, and multiple outlet channels. A diversion valve core, controlled by a third motor, is installed in the diversion valve core mounting cavity. The mixing water outlet channel is connected to the mixing water inlet channel, which is also connected to the inlet end of the diversion valve core. The multiple outlet ends of the diversion valve core are correspondingly connected to each of the outlet channels. The movable valve plate of the diversion valve core is driven to rotate by the third motor, allowing water to selectively flow through a specific outlet end and outlet channel. This water distribution function is particularly suitable for shower systems.
[0028] Compared with the prior art, the advantages of the aforementioned two technical solutions of this utility model are as follows:
[0029] 1. It consists of three independent modules, namely a flow regulation module, a pressure balancing module and a temperature regulation module connected in sequence. The valve cores in the flow regulation module and the temperature regulation module are controlled by motors, and these two modules can achieve automatic control. Each module exists and is controlled independently, which greatly simplifies the control method, greatly reduces the control difficulty and manufacturing difficulty, and greatly improves the control accuracy of water output and water temperature. They can also be selected and combined for use.
[0030] 2. The flow regulation module is used to synchronously regulate the flow rate of cold and hot water flowing into the pressure balancing module per unit time, thereby regulating the flow rate of mixed water flowing out of the temperature control module per unit time. The pressure balancing module is set to adjust the flow rate of cold and hot water by activating the balancing valve core in the pressure balancing module when there are fluctuations in the water pressure of cold and hot water, ensuring that the two are mixed in the preset ratio. This effectively solves the problem that the fluctuation range of the water output is large due to the water pressure difference, and the water temperature will fluctuate between hot and cold for a certain period of time. The total water volume passing through the pressure balancing module will remain basically unchanged.
[0031] 3. More importantly, this pressure balancing module is located at the inlet of the temperature control module, which makes the pressure of the hot and cold water flowing into the temperature control module relatively stable without fluctuations. This ensures that the adjustment of the temperature control valve core is less volatile and more stable. When fluctuations occur, the temperature control valve core basically remains unchanged, which better solves the problem of sudden changes in the outlet water temperature and further improves the user experience. Moreover, this can greatly reduce the requirements for program control, reduce costs, and improve the yield rate.
[0032] The third technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: It includes a flow regulation module and a temperature regulation module connected together. The flow regulation module includes a first valve seat, which has a first cold water inlet channel, a first hot water inlet channel, a flow valve core mounting cavity, a first cold water outlet channel, and a first hot water outlet channel. The flow valve core mounting cavity is equipped with a flow regulating valve core controlled by a first motor, which can regulate the outflow rate of the first cold water outlet channel and the first hot water outlet channel. The temperature regulation module includes a third valve seat, which has a third cold water inlet channel, a third hot water inlet channel, a temperature regulating valve core mounting cavity, a mixing chamber, and a mixed water outlet channel. The temperature regulating valve core mounting cavity is equipped with a temperature regulating valve core controlled by a second motor, which can regulate the mixing ratio of cold water and hot water flowing into the mixing chamber. The mixing chamber can be connected to the mixed water outlet channel. The first cold water outlet channel is connected to the third cold water inlet channel, and the first hot water outlet channel is connected to the third hot water inlet channel.
[0033] Compared with the prior art, the advantages of the third technical solution of this utility model are as follows: it is composed of two independent modules, namely a flow regulation module and a temperature regulation module connected in sequence. The valve cores in the flow regulation module and the temperature regulation module are controlled by motors, and these two modules can realize automated control. Each module exists and is controlled independently, which greatly simplifies the control method, greatly reduces the control difficulty and manufacturing difficulty, and greatly improves the control accuracy of water output and water temperature. They can also be selected and combined for use. Attached Figure Description

[0052] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0053] like Figures 1-9 The image shown is the first embodiment of this utility model.
[0054] A smart water temperature control module includes a flow regulation module 1, a pressure balancing module 2, and a temperature control module 3 connected in sequence.
[0055] The flow regulation module 1 includes a first valve seat 11, which has a first cold water inlet channel 1a, a first hot water inlet channel 1b, a flow valve core mounting cavity 1e, a first cold water outlet channel 1c, and a first hot water outlet channel 1d. The flow valve core mounting cavity 1e is equipped with a flow regulating valve core 12 controlled by a first motor 13. The flow regulating valve core 12 can regulate the outflow rate of the first cold water outlet channel 1c and the first hot water outlet channel 1d. The first cold water inlet channel 1a and the first hot water inlet channel 1b are arranged coaxially laterally. One flow valve core mounting cavity 1e is arranged coaxially with the first cold water outlet channel 1c, and the other flow valve core mounting cavity 1e is arranged coaxially with the first hot water outlet channel 1d.
[0056] In this embodiment, there are two flow valve core mounting cavities 1e and two flow regulating valve cores 12, with one flow regulating valve core 12 installed in each flow valve core mounting cavity 1e. The first cold water inlet channel 1a is connected to the inlet end of one of the flow regulating valve cores 12, and the outlet end of the flow regulating valve core 12 is connected to the first cold water outlet channel 1c. The moving valve plate of the flow regulating valve core 12 is driven to rotate by the first motor 13 to regulate the flow rate of cold water flowing out of the first cold water outlet channel 1c. The first hot water inlet channel 1b is connected to the inlet end of the other flow regulating valve core 12, and the outlet end of this flow regulating valve core 12 is connected to the first hot water outlet channel 1d. The moving valve plate of the flow regulating valve core 12 is driven to rotate by the first motor 13 to regulate the flow rate of hot water flowing out of the first hot water outlet channel 1d. The moving valve plates of each of the two flow regulating valve cores 12 are driven to rotate by one of the first motors 13.
[0057] The pressure balancing module 2 includes a second valve seat 21, which has a second cold water inlet channel 2a, a second hot water inlet channel 2b, a balancing valve core mounting cavity 2e, a second cold water outlet channel 2c, and a second hot water outlet channel 2d. A balancing valve core 22 is disposed within the balancing valve core mounting cavity 2e. The second valve seat 21 is formed by the mating of an upper valve seat 211 and a lower valve seat 212. The second cold water inlet channel 2a and the second hot water inlet channel 2b are located on the lower valve seat 212, while the balancing valve core mounting cavity 2e, the second cold water outlet channel 2c, and the second hot water outlet channel 2d are located on the upper valve seat 211. A sealing ring 213 is provided between the upper valve seat 211 and the valve seat 212.
[0058] The balancing valve core 22 includes a valve housing 221 and a balancing element 222 located inside the valve housing 221 that can slide laterally. Plugs 223 are provided on both sides of the balancing valve core mounting cavity 2e. The valve housing 221 is constrained between the two plugs 223 and its position is limited. The balancing valve core 22 includes the balancing element 222, which has a first inlet 22a connecting the second cold water inlet channel 2a to the second cold water outlet channel 2c, and a second inlet 22b connecting the second hot water inlet channel 2b to the second hot water outlet channel 2d. The lateral sliding of the balancing element 222 can change the degree of overlap between the first inlet 22a and the second cold water inlet channel 2a, and also change the degree of overlap between the second inlet 22b and the second hot water inlet channel 2b. Under water pressure, the lateral sliding of the balancing element 222 can automatically adjust the water flow distribution per unit time in the second cold water outlet channel 2c and the second hot water outlet channel 2d.
[0059] The temperature control module 3 includes a third valve seat 31, which has a third cold water inlet channel 3a, a third hot water inlet channel 3b, a temperature control valve core mounting cavity 3e, a mixing chamber 3c, and a mixed water outlet channel 3d. The temperature control valve core mounting cavity 3e is equipped with a temperature control valve core 32 controlled by a second motor 33. The temperature control valve core 32 can adjust the mixing ratio of cold water and hot water flowing into the mixing chamber 3c. The mixing chamber 3c is connected to the mixed water outlet channel 3d.
[0060] In this embodiment, there are two temperature-regulating valve core mounting cavities 3e and two temperature-regulating valve cores 32, with one temperature-regulating valve core 32 installed in each cavity 3e. The temperature-regulating valve core 32 is essentially the same as the valve plate of the flow-regulating valve core, regulating the water flow. The third cold water inlet channel 3a is connected to the inlet end of one of the temperature-regulating valve cores 32, and the outlet end of the temperature-regulating valve core 32 is connected to the mixing chamber 3c. The moving valve plate of the temperature-regulating valve core 32 is driven to rotate by the second motor 33 to regulate the flow rate of cold water into the mixing chamber 3c. The third hot water inlet channel 3b is connected to the inlet end of the other temperature-regulating valve core 32, and the outlet end of this temperature-regulating valve core 32 is connected to the mixing chamber 3c. The moving valve plate of this temperature-regulating valve core 32 is driven to rotate by the second motor 33 to regulate the flow rate of hot water into the mixing chamber 3c. Each of the moving valve plates of the two temperature-regulating valve cores 32 is driven to rotate by a second motor 33.
[0061] The first valve seat 11 and the second valve seat 21 are connected by a water pipe 7; the second valve seat 21 and the third valve seat 31 are connected by a water pipe 7, so that the first cold water outlet channel 1c, the second cold water inlet channel 2a, the second cold water outlet channel 2c, and the third cold water inlet channel 3a can be connected in sequence; the first hot water outlet channel 1d, the second hot water inlet channel 2b, the second hot water outlet channel 2d, and the third hot water inlet channel 3b can be connected in sequence.
[0062] A water flow generator 4 is also installed inside the mixing chamber 3c. The water flow generator 4 is a structure that uses water flow to generate electricity. It is an existing technology. The water flowing in from both sides drives the impeller of the water flow generator 4 to rotate, resulting in higher power generation efficiency. The electrical energy generated by the water flow generator 4 can supply the display screen, or it can supply the battery or other electrical components.
[0063] It also includes a mixing water temperature sensor 6c, a cold water temperature sensor 6a, and a hot water temperature sensor 6b; wherein, the sensing head of the mixing water temperature sensor 6c extends into the mixing water outflow channel 3d. The sensing head of the cold water temperature sensor 6a extends into the third cold water inlet channel 3a, and the sensing head of the hot water temperature sensor 6b extends into the third hot water inlet channel 3b.
[0064] The mixing water temperature sensor 6c, cold water temperature sensor 6a, and hot water temperature sensor 6b are electrically connected to the information control module, as is the motor control module. The information control module also includes touch buttons for setting the outlet water temperature and starting / stopping the machine. It also includes a display module electrically connected to the information control module, which displays the current water temperature, flow rate, and set outlet water temperature information.
[0065] Of course, the directions of entry for cold and hot water can be interchanged. That is, hot water can also enter through cold water channel 1a, and cold water can also enter through hot water channel 1b.
[0066] Cold and hot water enter the flow regulation module 1 respectively. The first motor 13 controls the opening angle of the flow regulation valve core 12 to achieve synchronous control of the cold and hot water flow. Then, they enter the pressure balancing module 2 respectively. The unstable water pressure is balanced by the movement of the balancing component 222 in the balancing valve core 22. Finally, they enter the temperature regulation module 3. The opening angle of the flow regulation valve core 12 at the cold end and the hot end is controlled according to the data detected by the mixing water temperature sensor 6c until the temperature reaches the set value and then stops. Finally, the mixed water comes out.
[0067] When water is introduced, hot and cold water flow in from the pressure and flow regulation module 1, then flow into the temperature regulation module 3 via the balance module 2. That is, the pressure balance module 2 is located between the flow regulation module 1 and the temperature regulation module 3, and finally the mixed water flows out from the temperature regulation module 3.
[0068] 1. It consists of three independent modules, namely the flow regulation module 1, the pressure balance module 2, and the temperature regulation module 3 connected in sequence. The valve cores in the flow regulation module 1 and the temperature regulation module 3 are controlled by corresponding motors, and the flow regulation module 1 and the temperature regulation module 3 can achieve automatic control. Each module exists and is controlled independently, which greatly simplifies the control method, greatly reduces the control difficulty and manufacturing difficulty, and greatly improves the control accuracy of water output and water temperature. They can also be selected and combined for use.
[0069] 2. The flow regulation module 1 is used to synchronously regulate the flow rate of cold water and hot water flowing into the pressure balance module 2 per unit time, thereby regulating the flow rate of mixed water flowing out of the temperature control module 3 per unit time. The pressure balance module 2 is set so that when there is a fluctuation in the water pressure of cold and hot water, the balance valve core 22 in the pressure balance module 2 will be activated to regulate the flow rate of cold and hot water, ensuring that the two are mixed in the preset ratio. This effectively solves the problem that the fluctuation range of the water output is large due to the water pressure difference, and the water temperature will fluctuate between hot and cold within a certain period of time. The total water volume passing through the pressure balance module 2 per unit time will basically change.
[0070] 3. More importantly, the pressure balancing module 2 is located at the inlet of the temperature control module 3, which makes the pressure of hot and cold water flowing into the temperature control module 3 relatively stable without fluctuations. This ensures that the adjustment of the temperature control valve core 32 is less volatile and more stable. When fluctuations occur, the temperature control valve core 32 basically remains unchanged in its original position, which better solves the problem of sudden changes in the outlet water temperature and further improves the user experience. Moreover, this can greatly reduce the requirements for program control, reduce costs, and improve the yield rate.
[0071] like Figure 10 The following is a second embodiment of the present invention.
[0072] The difference between this embodiment and the first embodiment is that the second cold water outlet channel 2c, the first cold water inlet channel 1a, the first cold water outlet channel 1c, and the third cold water inlet channel 3a can be connected sequentially. The second hot water outlet channel 2d is connected to the first cold water inlet channel 1a via a water pipe 7, and the first hot water outlet channel 1d is connected to the third hot water inlet channel 3b via a water pipe 7. During water intake, cold and hot water flow into the pressure balancing module 2 from the second cold water inlet channel 2a and the second hot water inlet channel 2b, respectively, and then flow into the temperature control module 3 via the flow regulation module 1. Finally, the mixed water flows out from the temperature control module 3. That is, the flow regulation module 1 is located between the pressure balancing module 2 and the temperature control module 3.
[0073] like Figure 11 , 12 The following is a third embodiment of the present invention.
[0074] The difference between this embodiment and the first embodiment is that: the first valve seat 11 and the second valve seat 21 are interlocked and can be further fixed together with screws, connecting the first cold water outlet channel 1c to the second cold water inlet channel 2a, and the first hot water outlet channel 1d to the second hot water inlet channel 2b; the second valve seat 21 and the third valve seat 31 are interlocked and can be further fixed together with screws, connecting the second cold water outlet channel 2c to the third cold water inlet channel 3a, and the second hot water outlet channel 2d to the third hot water inlet channel 3b. The entire module can be integrated into a single housing.
[0075] like Figure 13 , 14 The image shown is the fourth embodiment of this utility model.
[0076] The difference between this embodiment and the third embodiment is that it also includes a diversion module 5. The diversion module 5 includes a fourth valve seat 51, which has a mixed water inflow channel 5a, a water diversion valve core mounting cavity 5b, and multiple water outlet channels 5c. A water diversion valve core 52 controlled by a third motor 53 is installed in the water diversion valve core mounting cavity 5b. The mixed water outflow channel 3d is connected to the mixed water inflow channel 5a, and the mixed water inflow channel 5a is connected to the inlet end of the water diversion valve core 52. The multiple outlet ends of the water diversion valve core 52 are correspondingly connected to each of the aforementioned water outlet channels 5c. The moving valve plate of the water diversion valve core 52 is driven to rotate by the third motor 53, so that the water flows out through a corresponding outlet end and a corresponding water outlet channel 5c. The valve plate assembly of the water diversion valve core 52 is similar to that of conventional water diversion valve cores on the market.
[0077] The diversion module 5 can also use a water pipe to connect the mixed water outflow channel 3d with the mixed water inflow channel 5a.
[0078] like Figure 15 The image shown is the fifth embodiment of this utility model.
[0079] The difference between this embodiment and the first embodiment is that there is only one flow valve core mounting cavity 1e and one flow regulating valve core 12; the first cold water inlet channel 1a is connected to the cold water inlet end of the flow regulating valve core 12, and the cold water outlet end of the flow regulating valve core 12 is connected to the first cold water outlet channel 1c; the first hot water inlet channel 1b is connected to the hot water inlet end of the flow regulating valve core 12, and the hot water outlet end of the flow regulating valve core 12 is connected to the first hot water outlet channel 1d; the moving valve plate of the flow regulating valve core 12 is driven to rotate by the first motor 13 to adjust the water flow of the first cold water outlet channel 1c and the first hot water outlet channel 1d.
[0080] There is only one temperature control valve core mounting cavity 3e and one temperature control valve core 32; the third cold water inlet channel 3a is connected to the cold water inlet end of the temperature control valve core 32, the third hot water inlet channel 3b is connected to the hot water inlet end of the temperature control valve core 32, the mixing water outlet end of the temperature control valve core 32 is connected to the mixing chamber 3c, and the moving valve plate of the temperature control valve core 32 is driven to rotate by the second motor 33 to realize the mixing ratio adjustment of cold water and hot water.
[0081] This temperature control valve core 3 is a swing-open mixing valve core, which is the valve core structure of existing household temperature control faucets. The only difference is that the driving method is motor drive, and the specific valve plate group is the existing temperature control valve plate group structure. Compared with the aforementioned method of using a dual valve core structure to adjust water temperature, it has a lower cost and a more compact structure.
[0082] like Figure 16 ,17 The image shown is the sixth embodiment of this utility model.
[0083] The difference between this embodiment and the first embodiment is that the moving valve plates of the two flow control valve cores 12 are driven to rotate by the same first motor 13, and the first motor 13 is connected to the moving valve plates of the two flow control valve cores 12 respectively through the same set of reduction components.
[0084] The moving valve plates of the two temperature control valve cores 32 are driven to rotate by the same second motor 33, and the second motor 33 is connected to the moving valve plates of the two temperature control valve cores 32 respectively through the same set of reduction gear components.
[0085] like Figure 18 The image shown is the seventh embodiment of this utility model.
[0086] The difference between this embodiment and the first embodiment is that the pressure balancing module 2 is omitted.
