Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and particularly to a faucet, a water purification system and a water temperature control system having the same. Background Art

[0002] With the pursuit of the public for the quality of life, smart home appliances have gradually entered people's lives.

[0003] Generally, household faucets for taking water are mechanical, and a mechanical valve is provided thereon. Users perform the action of taking water by operating the mechanical valve. If a pipeline machine is connected, the connected faucet is usually an electric control faucet. Users can control the electric control faucet through a controller, even remotely, so as to achieve the action of taking water.

[0004] However, with the increase in household appliances and the coexistence of mechanical faucets and electric control faucets, the water-taking devices of users will also increase. Even if a mechanical faucet and an electric control faucet are set at the same place at the same time, it is very inconvenient for users to use and wastes the use space. Summary of the Invention

[0005] In order to at least partially solve the problems existing in the prior art, the present invention provides a faucet, comprising: a faucet body having a mixing chamber, a first water inlet passage, a second water inlet passage and a water outlet passage, wherein the first water inlet passage and the second water inlet passage communicate with the bottom of the mixing chamber, and the water outlet passage communicates with the top of the mixing chamber; a mechanical valve including a mechanical valve core and a mechanical handle, at least a part of the mechanical valve core is disposed in the first water inlet passage, the mechanical handle is connected to the mechanical valve core, and the mechanical handle drives the mechanical valve core to control the on / off of the first water inlet passage; and a solenoid valve including a solenoid valve core and a faucet controller, at least a part of the solenoid valve core is disposed in the second water inlet passage, and the faucet controller controls the movement of the solenoid valve core in response to a switch operation of a user to control the on / off of the second water inlet passage.

[0006] It can be seen therefrom that the faucet has two water inlet channels, which can be respectively connected to two different waterways. The two water inlet channels are respectively controlled by a mechanical valve and a solenoid valve, and after mixing, they are delivered to the user through a water outlet channel. This can avoid the user installing two faucets simultaneously and save the user's usage space. Moreover, a mixing chamber is provided between the water inlet channel and the water outlet channel of the faucet, which can fully mix the water flows from the two different waterways in the mixing chamber, thereby increasing the usage range of the faucet. On this basis, the faucet can directly control the water outlet of the faucet through a mechanical handle, or can control the water outlet of the faucet through a faucet controller, or can also control the water outlet of the faucet through the mechanical handle and the faucet controller at the same time. Therefore, the usage range of the faucet is further expanded, making the faucet adaptable to more scenarios.

[0007] Exemplarily, the mechanical valve further includes a mechanical valve seat and a mechanical valve sleeve. The mechanical valve seat is arranged on the first water inlet channel. One end of the mechanical valve sleeve is connected to the mechanical valve seat. The mechanical valve core is arranged in the mechanical valve seat and the mechanical valve sleeve. The mechanical handle is connected to the mechanical valve core at the other end of the mechanical valve sleeve.

[0008] The mechanical valve with the above structure is simple in structure and convenient for installation and maintenance.

[0009] Exemplarily, the solenoid valve further includes a solenoid valve seat and an electromagnetic coil. The solenoid valve seat is arranged on the second water inlet channel. One end of the solenoid valve core is arranged in the solenoid valve seat, and the electromagnetic coil is arranged at the other end of the solenoid valve core. The electromagnetic coil is connected to the faucet controller. The faucet controller controls the energization state of the electromagnetic coil in response to the user's switch operation. The solenoid valve core moves relative to the solenoid valve seat when the energization state changes to control the on / off of the second water inlet channel.

[0010] It can be seen therefrom that the solenoid valve with this structure is simple in structure and easy to operate.

[0011] Exemplarily, the faucet controller is arranged on the top surface of the electromagnetic coil. Thus, the faucet controller and the electromagnetic coil are arranged on the same side of the faucet body. In this way, the structure of the faucet is relatively compact and occupies less space.

[0012] Exemplarily, the mixing chamber has a gradually decreasing size from bottom to top.

[0013] In this way, the water flow flows from the end with a large cross-sectional area to the end with a small cross-sectional area, and the flow rate will increase. And during the flowing process, it collides with the inner wall of the mixing chamber to generate a turbulent flow in the mixing chamber, thereby enabling the water in the two water inlet channels to be more fully mixed in the mixing chamber.

[0014] Exemplarily, the first water inlet channel and the second water inlet channel extend in the vertical direction. Among them, the first axis of the mechanical valve core and the second axis of the solenoid valve core extend in the horizontal direction, and the first axis is perpendicular to the second axis.

[0015] This arrangement can enable the mechanical valve and the solenoid valve to be distributed in different areas of the faucet body. Moreover, when installing the faucet, both the mechanical valve and the solenoid valve can face the user direction, which can facilitate the user's operation of the two switches. At the same time, when the user operates the mechanical valve and the solenoid valve simultaneously, they do not interfere with each other. And the structure of this faucet is more compact.

[0016] Exemplarily, the faucet further includes: a first temperature sensor for detecting the first water temperature in the first water inlet channel and outputting a first temperature signal; a second temperature sensor for detecting the second water temperature in the second water inlet channel and outputting a second temperature signal; a control panel, the control panel includes an input device and a controller, the input device is used to receive the set water temperature input by the user, and the controller controls the opening time of the solenoid valve based on the first temperature signal and the second temperature signal so that the temperature in the mixing chamber reaches the set water temperature.

[0017] It can be seen from this that the faucet with the above structure can mix water at different temperatures in the mixing chamber according to the water temperature set by the user, and realize instant heating and instant output, reducing the user's manual regulation of the water temperature and improving the user's experience.

[0018] Exemplarily, the controller controls the energization duration and / or power-off duration of the electromagnetic coil in each cycle based on the first temperature signal and the second temperature signal so that the temperature in the mixing chamber reaches the set water temperature.

[0019] It can be seen from this that the faucet with the above structure can more accurately automatically mix water at different temperatures in the mixing chamber according to the water temperature set by the user, improving the user's experience.

[0020] Exemplarily, the faucet controller is integrated into the control panel.

[0021] In this way, the integration degree of the faucet can be improved and the size of the faucet can be reduced. At the same time, modularizing the faucet can reduce the cost of the faucet.

[0022] Exemplarily, the control panel further includes a display for displaying the first water temperature, the second water temperature and / or the set water temperature.

[0023] In this way, it can be convenient for the user to timely and accurately understand the water temperature situation in the current water circuit and the set water temperature situation of the faucet.

[0024] According to another aspect of the present invention, there is also provided a water purification system, which includes a booster pump and a reverse osmosis filter element connected to the water outlet of the booster pump. The water purification system further includes a first water intake waterway, a second water intake waterway, a water storage waterway, a water tank, and a faucet as described above. One end of the first water intake waterway is connected to the pure water outlet of the reverse osmosis filter element, and the other end of the first water intake waterway is connected to the first water inlet channel of the faucet. A check valve and a high-pressure switch are sequentially arranged on the first water intake waterway along the water flow direction; one end of the second water intake waterway is connected to the water tank, and the other end of the second water intake waterway is connected to the second water inlet channel of the faucet. A water pump is arranged on the second water intake waterway; one end of the water storage waterway is connected to the water tank, and the other end of the water storage waterway is connected to the first water intake waterway downstream of the high-pressure switch. A water storage solenoid valve is arranged on the water storage waterway.

[0025] It can be seen therefrom that by separately arranging the second water intake waterway connected to the solenoid valve and the water storage waterway, it can effectively avoid the situation where when a water intake signal is sent from the water intake end, due to the high back pressure in the pipeline where the water storage solenoid valve is located, the solenoid valve cannot be conducted in time, resulting in the user being unable to obtain water.

[0026] Exemplarily, the water purification system includes a system controller, and the system controller is connected to the faucet controller. The system controller turns on the booster pump, the water pump, and the water storage solenoid valve when the solenoid valve is opened; and the system controller is connected to the high-pressure switch, and the system controller turns on the booster pump when the high-pressure switch is triggered.

[0027] It can be seen therefrom that for the water purification system with the above settings, on the one hand, when the user turns on the mechanical valve and the solenoid valve at the same time, two-way water supply can be carried out, thereby increasing the water intake amount of the user per unit time. On the other hand, when the user only turns on the solenoid valve, water will be pumped from the water tank and water will be produced into the water tank at the same time. Therefore, the time for the faucet to discharge water at a relatively high flow rate is extended. These two aspects can both improve the user experience.

[0028] Exemplarily, the system controller turns off the water pump when the solenoid valve is closed.

[0029] In this way, it is avoided that the water pump continues to work when the second water inlet channel is blocked, which avoids the loss of the service life of the water pump and saves the power consumption of the water purification system.

[0030] Exemplarily, a liquid level sensor is arranged on the water tank. The liquid level sensor outputs a low liquid level signal when the liquid level in the water tank is lower than the upper liquid level limit. The system controller keeps the booster pump and the water storage solenoid valve turned on according to the low liquid level signal received from the liquid level sensor.

[0031] In this way, it can be ensured that after the user takes water from the water tank each time, a water storage operation will be performed on the water tank, and water can be stored in the water tank in a timely manner, enabling the user to obtain a larger flow rate and more water each time when taking water through the solenoid valve. At the same time, since water is stored in the water tank as long as the solenoid valve is opened, the dry running of the water pump can be avoided.

[0032] Exemplarily, when the liquid level in the water tank is higher than the upper liquid level limit, the liquid level sensor outputs a high liquid level signal, and the system controller closes the booster pump and the water storage solenoid valve when receiving the high liquid level signal.

[0033] In this way, it can be avoided that the water in the water tank is too much and overflows, affecting the user experience.

[0034] Exemplarily, the water purification system further includes a pipeline machine interface, and the pipeline machine interface is connected to the first water intake waterway downstream of the high-pressure switch.

[0035] In this way, the application range of the water purification system can be expanded, making the applicable range of the water purification system wider.

[0036] According to another aspect of the present invention, a water temperature control system is further provided, including the faucet, cold water pipeline, hot water pipeline and operation panel as described above. The first water inlet channel is connected to one of the cold water pipeline and the hot water pipeline, and the second water inlet channel is connected to the other of the cold water pipeline and the hot water pipeline.

[0037] It can be seen from this that for the water temperature control system with the above structure, the user can accurately pick up water at the set temperature, reducing the manual adjustment of the water temperature by the user and improving the user experience.

[0038] A series of simplified concepts are introduced in the summary of the invention, which will be further described in detail in the detailed implementation section. The summary of the invention does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the protection scope of the claimed technical solution.

[0047] In the following description, a large number of details are provided to enable a thorough understanding of the present invention. However, those skilled in the art can understand that the following description only exemplarily shows the preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some well-known technical features in the art are not described in detail

[0048] Exemplarily, as Figure 1-2 shown, a faucet 100 includes: a faucet body 200, a mechanical valve 300 and a solenoid valve 400

[0049] The faucet body 200 has a mixing chamber 210, a first water inlet channel 220, a second water inlet channel 230, and a water outlet channel 240. The first water inlet channel 220 and the second water inlet channel 230 are both connected to the bottom of the mixing chamber 210, and the water outlet channel 240 is connected to the top of the mixing chamber 210. The water flowing into the mixing chamber 210 through the first water inlet channel 220 and the second water inlet channel 230 can be mixed first in the mixing chamber 210 and then flow out through the water outlet channel 240.

[0050] In one embodiment, the first water inlet channel 220 and the second water inlet channel 230 can be connected to water paths with different temperatures. After being mixed into water at the user-set temperature in the mixing chamber 210, it then flows out through the water outlet channel 240. In another embodiment, it can also be for increasing the water output, connecting the first water inlet channel 220 and the second water inlet channel 230 to two independent water supply paths. When taking water, the two water inlet channels supply water simultaneously. After being mixed in the mixing chamber 210, it is discharged through the water outlet channel.

[0051] The mechanical valve 300 on the faucet 100 includes a mechanical valve core 330 and a mechanical handle 340. At least a part of the mechanical valve core 330 is arranged in the first water inlet channel 220, the mechanical handle 340 is connected to the mechanical valve core 330, and the mechanical handle 340 drives the mechanical valve core 330 to control the on / off of the first water inlet channel 220.

[0052] The movement mode of the mechanical valve core 330 in the first water inlet channel 220 can be rotary or translational. By changing the position of the mechanical valve core 330 in the first water inlet channel 220, the first water inlet channel 220 can be made on or off. The structure of the mechanical valve core 330 can have various types. The mechanical valve core 330 can adopt various structures known to those skilled in the art, which will not be elaborated herein.

[0053] The solenoid valve 400 on the faucet 100 includes a solenoid valve core 420 and a faucet controller 440. At least a part of the solenoid valve core 420 is arranged in the second water inlet channel 230. In one embodiment, the solenoid valve core 420 is a sliding valve core, and the sliding valve core can move linearly in the second water inlet channel 230. The faucet controller 440 responds to the user's switch operation to control the movement of the solenoid valve core 420 to control the on / off of the second water inlet channel 230.

[0054] The faucet controller 440 can be various types of controllers such as a switch type, a button type, a touch screen type, etc., as long as it can receive the user's switch operation and control the movement of the solenoid valve core 420 when receiving the user's switch operation.

[0055] It can be seen from this that the faucet 100 has two water inlet channels, which can be respectively connected to two different waterways. The two water inlet channels are respectively controlled by a mechanical valve 300 and a solenoid valve 400, and after mixing, they are delivered to the user through a water outlet channel. Thus, it is possible to avoid the user installing two faucets simultaneously, saving the user's usage space. Moreover, a mixing chamber 210 is provided between the water inlet channel and the water outlet channel of the faucet 100, which can fully mix the water flows from the two different waterways in the mixing chamber 210, increasing the usage range of the faucet 100. On this basis, the faucet 100 can directly control the water outlet of the faucet 100 through the mechanical handle 340, or control the water outlet of the faucet 100 through the faucet controller 440, or simultaneously control the water outlet of the faucet 100 through the mechanical handle 340 and the faucet controller 440. Therefore, the usage range of the faucet 100 is further expanded, enabling the faucet 100 to adapt to more scenarios.

[0056] Exemplarily, the mechanical valve 300 further includes a mechanical valve seat 310 and a mechanical valve sleeve 320. The mechanical valve seat 310 is disposed on the first water inlet channel 220. The mechanical valve seat 310 can serve as the installation base for the mechanical valve sleeve 320 and the mechanical valve core 330. One end of the mechanical valve sleeve 320 is connected to the mechanical valve seat 310. The mechanical valve core 330 is disposed within the mechanical valve seat 310 and the mechanical valve sleeve 320, and the mechanical handle 340 is connected to the mechanical valve core 330 at the other end of the mechanical valve sleeve 320. The mechanical valve core 330 can move within the mechanical valve sleeve 320 along with the mechanical handle 340 to control the opening and closing of the first water inlet channel 220. The movement mode is the same as that described above, and can be rotary or translational.

[0057] The mechanical valve 300 with the above structure is simple in structure and convenient for installation and maintenance.

[0058] Exemplarily, the solenoid valve 400 further includes a solenoid valve seat 410 and a solenoid coil 430. The solenoid valve seat 410 is disposed on the second water inlet channel 230. One end of the solenoid valve core 420 is disposed within the solenoid valve seat 410, and the solenoid coil 430 is disposed at the other end of the solenoid valve core 420. The solenoid coil 430 is connected to the faucet controller 440. The faucet controller 440 controls the energization state of the solenoid coil 430 in response to the user's switch operation. The solenoid valve core 420 moves relative to the solenoid valve seat 410 when the energization state changes to control the opening / closing of the second water inlet channel 230.

[0059] In one embodiment, the solenoid valve seat 410 is a spool valve sleeve, and the solenoid valve core 420 is a spool valve core. The spool valve core can move linearly within the spool valve sleeve. Usually, a return spring is also arranged within the spool valve sleeve, and its function is to enable the spool valve core to have a normal position, which is usually a position capable of blocking the water flow channel. When the faucet controller 440 receives the user's instruction to open the faucet, the faucet controller 440 will control the electromagnetic coil 430 to be energized, generating a magnetic field. Under the action of the magnetic force, the restoring force of the return spring is offset, and the spool valve core is pushed to move within the spool valve sleeve. The movement of the spool valve core can conduct the second water inlet channel 230, thereby realizing the water outlet of the faucet. When the faucet controller 440 receives the user's instruction to close the faucet, the faucet controller 440 will control the electromagnetic coil 430 to lose power, the magnetic field disappears, and the spool valve core moves within the spool valve sleeve under the action of the restoring force of the return spring, blocking the second water inlet channel 230, thereby realizing the water cutoff of the faucet.

[0060] It can be seen from this that the solenoid valve 400 with this structure is simple in structure and easy to operate.

[0061] Exemplarily, the faucet controller 440 can be arranged on the top surface of the electromagnetic coil 430. The faucet controller 440 and the electromagnetic coil 430 are arranged on the same side of the faucet body 200. In this way, the structure of the faucet is relatively compact and occupies less space.

[0062] Exemplarily, the mixing chamber 210 has a gradually decreasing size from bottom to top. In one embodiment, the outer shape of the mixing chamber 210 can be frustum-shaped, as Figure 2 shown.

[0063] In this way, the water flow moves from the end with a large cross-sectional area to the end with a small cross-sectional area, the flow rate will increase, and during the flow process, it collides with the inner wall of the mixing chamber 210 to generate a turbulent flow within the mixing chamber 210, and further the water in the two water inlet channels can be more fully mixed within the mixing chamber 210.

[0064] Exemplarily, when the faucet 100 is in normal use, it is placed at the position shown in Figure 1 , the first water inlet channel 220 and the second water inlet channel 230 extend vertically within the faucet body 200. The mechanical valve seat 310 and the solenoid valve seat 410 are located on the side surface of the faucet body 200. The first axis of the mechanical valve core 330 and the second axis of the solenoid valve core 420 extend horizontally. And the first axis is perpendicular to the second axis. That is, if viewed from the top of the faucet 100 downwards, the mechanical valve 300 and the solenoid valve 400 are arranged at a right angle. The faucet controller 440 can be arranged on the top surface of the electromagnetic coil 430.

[0065] This arrangement allows the mechanical valve 300 and the solenoid valve 400 to be distributed in different areas of the faucet body 200. Moreover, when installing the faucet 100, both the mechanical valve 300 and the solenoid valve 400 can face the user direction, which facilitates the user's operation of the two switches. At the same time, when the user operates the mechanical valve 300 and the solenoid valve 400 simultaneously, they do not interfere with each other. And the structure of the faucet 100 is more compact.

[0066] Exemplarily, the faucet 100 further includes a first temperature sensor 251, a second temperature sensor 252, and a control panel 900. The first temperature sensor 251 is used to detect the first water temperature in the first water inlet passage 220 and output a first temperature signal. The second temperature sensor 252 is used to detect the second water temperature in the second water inlet passage 230 and output a second temperature signal.

[0067] The control panel 900 includes an input device and a controller. The input device is used to receive the set water temperature input by the user. The control panel 900 can control the opening time of the solenoid valve 400 based on the first temperature signal and the second temperature signal, so that the temperature in the mixing chamber 210 reaches the set water temperature.

[0068] In one embodiment, the first water inlet passage 220 is connected to the cold water pipe, and the second water inlet passage 230 is connected to the hot water pipe. The mechanical valve 300 controls the on / off of the first water inlet passage 220, and cold water (i.e., normal temperature water) flows through it; the solenoid valve 400 controls the second water inlet passage 230, and hot water flows through it. When the user inputs the desired water temperature on the input device and simultaneously opens the mechanical valve 300 and the solenoid valve 400, the controller will control the opening time of the solenoid valve 400 according to the collected first temperature signal and second temperature signal. If the opening time of the solenoid valve 400 is long, the water temperature in the mixing chamber 210 is higher; if the opening time of the solenoid valve 400 is short, the water temperature in the mixing chamber 210 is lower.

[0069] Optionally, the first water inlet passage 220 can also be connected to the hot water pipe, and hot water flows through it. The second water inlet passage 230 is connected to the cold water pipe, and cold water flows through it. The principle is the same as above.

[0070] It can be seen from this that the faucet 100 with the above structure can mix water at different temperatures in the mixing chamber 210 according to the water temperature set by the user, and achieve instant heating and instant output, reducing the user's manual adjustment of the water temperature and improving the user's experience.

[0071] Further, the controller may control the energization duration and / or the power-off duration of the solenoid valve 400 in each cycle based on the first temperature signal and the second temperature signal, so that the temperature in the mixing chamber 210 reaches the set water temperature. In one embodiment, the first water inlet passage 220 is connected to a cold water pipe, the second water inlet passage 230 is connected to a hot water pipe, the mechanical valve 300 controls the on-off of the first water inlet passage 220, and cold water (i.e., normal temperature water) flows therein; the solenoid valve 400 controls the second water inlet passage 230, and hot water flows therein. When the user inputs the desired water temperature on the input device and simultaneously opens the mechanical valve 300 and the solenoid valve 400, the controller may, according to the collected first temperature signal and second temperature signal, cause the second water inlet passage 230 controlled by the solenoid valve 400 to supply water to the mixing chamber 210 in a pulsed manner.

[0072] Exemplarily, the controller may adjust the amount of hot water delivered to the mixing chamber 210 in each cycle by changing the energization duration of the solenoid valve 400 while keeping the power-off duration unchanged, thereby controlling the water temperature obtained by the user. One energization and one power-off constitute a cycle. Exemplarily, the controller may also adjust the amount of cold water delivered to the mixing chamber 210 in each cycle by changing the power-off duration of the solenoid valve 400 while keeping the energization duration unchanged, thereby controlling the water temperature obtained by the user. Exemplarily, the controller may simultaneously change the energization duration and the power-off duration of the solenoid valve 400 to control the water temperature obtained by the user. In this case, the duration of each cycle may be fixed. For example, when the water temperature obtained when both the energization duration and the power-off duration are 2 seconds is lower than the temperature set by the user, the energization duration may be extended and the power-off duration may be shortened. For example, the energization duration may be set to 3 seconds and the power-off duration may be set to 1 second, so as to increase the water temperature in the mixing chamber 210.

[0073] Optionally, the first water inlet passage 220 may also be connected to a hot water pipe, and hot water flows therein, and the second water inlet passage 230 is connected to a cold water pipe, and cold water flows therein. Cold water is delivered to the mixing chamber 210 in a pulsed manner according to a set cycle, and the temperature of the water in the mixing chamber 210 can also reach the water temperature set by the user. The control of the cycle by the controller is the same as that in the above embodiment.

[0074] It can be seen from this that the faucet 100 having the above structure can more accurately automatically mix waters of different temperatures in the mixing chamber 210 according to the water temperature set by the user, improving the user experience.

[0075] Exemplarily, the faucet controller 440 may be integrated into the control panel 900. In this way, the integration degree of the faucet 100 can be improved, and the size of the faucet 100 can be reduced. At the same time, modularizing the faucet 100 can reduce the cost of the faucet 100.

[0076] Exemplarily, the control panel 900 further includes a display 930 for displaying the first water temperature, the second water temperature, and / or the set water temperature. The user can view the water temperature in the first water inlet passage 220, the water temperature in the second water inlet passage 230, and / or the set water temperature of the user through the display 930.

[0077] In this way, it is convenient for the user to timely and accurately understand the water temperature situation in the current water path and the set water temperature situation of the faucet 100.

[0078] In the existing water purification system, usually a water storage solenoid valve and a water pump are connected in series on the water storage pipeline, and both the water storage stage to the water tank and the water pumping stage from the water tank are completed through this water storage pipeline. As is well known to those skilled in the art, usually, when the water storage solenoid valve operates normally, the back pressure cannot exceed 0.05 MPa, while in the commonly used water purification system, the back pressure of the pipeline where the water storage solenoid valve is located usually exceeds 0.25 MPa or higher. In this way, the water storage solenoid valve will fail to work properly. This will cause the electric control faucet to send a water intake signal, and the water pump has already started to draw water from the water tank, but due to the high back pressure, the water storage solenoid valve cannot actuate, thus failing to conduct the water storage pipeline. In this way, the user cannot receive water, and the water pump is pumping water with the outlet blocked. Over time, the lifespan of the water pump will be reduced. If the water intake end is connected to a pipeline machine and the user heats the water flowing out through the pipeline machine, then when the same situation occurs after the pipeline machine sends a water intake signal, the pipeline machine will dry burn without water, which is extremely dangerous.

[0079] To avoid the above situations, according to another aspect of the present invention, a water purification system 500 is further provided, as Figure 3 shown, including a booster pump 510 and a reverse osmosis filter element 520 connected to the water outlet of the booster pump 510. The booster pump 510 is used to press the raw water into the reverse osmosis filter element 520, and under the action of the reverse osmosis filter element, the filtered pure water is discharged from the pure water outlet of the reverse osmosis filter element. The working principle of the reverse osmosis filter element 520 is well known to those skilled in the art and will not be described in detail.

[0080] The water purification system 500 further includes any one of the faucets 100 as described above. In addition, the water purification system 500 further includes a first water intake water path 530, a second water intake water path 540, a water storage water path 550, and a water tank 560.

[0081] One end of the first water intake water path 530 is connected to the pure water outlet 521 of the reverse osmosis filter element 520, and the other end of the first water intake water path 530 is connected to the first water inlet passage 220 of the faucet 100. A check valve 531 and a high-pressure switch 532 are sequentially arranged on the first water intake water path 530 along the water flow direction.

[0082] One end of the second water intake channel 540 is connected to the water tank 560, and the other end of the second water intake channel 540 is connected to the second water inlet passage 230 of the faucet 100. A water pump 541 is provided on the second water intake channel 540.

[0083] One end of the water storage channel 550 is connected to the water tank 560, and the other end of the water storage channel 550 is connected to the first water intake channel 530 downstream of the high-pressure switch 532. A water storage solenoid valve 551 is provided on the water storage channel 550.

[0084] When the user moves the mechanical valve core 330 through the mechanical handle 340, the mechanical valve 300 will make the first water inlet passage 220 conduct. In this way, on the first water intake channel 530, from the first water inlet passage 220 to the check valve 531 will be in communication with the atmosphere, the pressure will decrease. After the high-pressure switch 532 detects the pressure drop, the high-pressure switch 532 will close (be triggered). After the booster pump 510 receives the electrical signal of the closing of the high-pressure switch 532, it will start and begin to pump water into the reverse osmosis filter element 520. The pure water flows through the first water intake channel 530 to the first water inlet passage 220 and is finally taken by the user.

[0085] When the user makes the first water inlet passage 220 cut off by operating the mechanical valve 300, the booster pump 510 is still continuing to produce water for the first water intake channel 530 until the pressure in the first water intake channel 530 exceeds the set value of the high-pressure switch 532, the high-pressure switch 532 will disconnect. After the booster pump 510 receives the electrical signal of the disconnection of the high-pressure switch 532, it will stop producing water. At this time, under the action of the check valve 531, the pressure in the first water intake channel 530 will be maintained high, and the water purification system 500 will enter the standby state.

[0086] When the user opens the solenoid valve 400 through the faucet controller 440, the electromagnetic coil 430 will be energized and generate a magnetic field. The magnetic field will move the solenoid valve core 420 and make the second water inlet passage 230 conduct. At the same time, the water pump 541 will also receive the water intake electrical signal sent by the faucet controller 440 and start the water pump 541. The water pump 541 will extract the already prepared pure water from the water tank 560 and discharge it from the faucet 100 through the second water inlet passage 230.

[0087] When the user operates the faucet controller 440 to close the solenoid valve 400, the electromagnetic coil 430 will be de-energized, the magnetic field will disappear, the solenoid valve core 420 can return to the initial position, and the second water inlet passage 230 will be cut off. At the same time, the water pump 541 will also receive the stop water intake electrical signal sent by the faucet controller 440 and stop the water pump 541. The water purification system 500 will enter the standby state.

[0088] That is to say, whether the user turns on the mechanical valve 300 or the solenoid valve 400, it will cause the high-pressure switch 532 to be triggered, the booster pump 510 to start, and the reverse osmosis filter element 520 to start making water.

[0089] Since the second water intake waterway 540 is connected to the water tank 560, it is necessary to ensure that the water tank 560 is pre-filled with prepared pure water. There are various methods for detecting the water storage volume in the water tank 560. A weight detection device can be set in the water tank 560 to judge the water volume in the water tank by detecting the weight of the water tank. A preferred embodiment will be provided below.

[0090] When the water storage solenoid valve 551 receives that the water volume in the water tank 560 is lower than the predetermined value, it will open the water storage solenoid valve 551. The water storage solenoid valve 551 has a conducting state and a cut-off state. After the water storage solenoid valve 551 is conducted, the first water intake waterway 530, the water storage waterway 550, and the water tank 560 will be connected, and the pressure of the first water intake waterway 530 will decrease. After the high-pressure switch 532 detects the pressure drop, the high-pressure switch 532 will close. After the booster pump 510 receives the electrical signal of the closed high-pressure switch 532, it will start and start pumping water into the reverse osmosis filter element 520. The pure water passes through the check valve 531, the first water intake waterway 530, and the water storage waterway 550, and finally enters the water tank 560.

[0091] Until the water tank 560 is full of water, the water storage solenoid valve 551 will cut off the water storage waterway 550. At this time, the booster pump 510 is still making water into the first water intake waterway 530. Until the pressure in the first water intake waterway 530 exceeds the set value of the high-pressure switch 532, the high-pressure switch 532 will disconnect. After the booster pump 510 receives the electrical signal of the disconnected high-pressure switch 532, it will stop making water. At this time, due to the action of the check valve 531, the pressure in the first water intake waterway 530 will be maintained at a high level, and the water purification system 500 will enter the standby state.

[0092] It can be seen from this that separating the second water intake waterway 540 connected to the solenoid valve 400 from the water storage waterway 550 can effectively avoid the situation where the water intake signal is sent from the water intake end, but due to the high back pressure of the pipeline where the water storage solenoid valve 551 is located, it cannot be conducted in time, resulting in the user being unable to receive water.

[0093] Exemplarily, the water purification system 500 includes a system controller, which is connected to the faucet controller 440. The system controller turns on the booster pump 510, the water extraction pump 541, and the water storage solenoid valve 551 when the solenoid valve 400 is opened. Specifically, when the user performs a water extraction operation on the faucet controller 440, the electromagnetic coil 430 changes from de-energized to energized, and the system controller will turn on the booster pump 510, the water extraction pump 541, and the water storage solenoid valve 551. And the system controller is connected to the high-pressure switch 532, and the system controller turns on the booster pump 510 when the high-pressure switch 532 is triggered.

[0094] The situation where one of the mechanical valve 300 and the solenoid valve 400 is opened can be referred to the corresponding description in the above text. When the mechanical valve 300 and the solenoid valve 400 are opened simultaneously, the water produced by the booster pump 510 will have two water paths to go, that is, it can be transported to the first water inlet channel 220 of the faucet 100 via the first water extraction water path 530, or it can be transported to the water tank 560 via the water storage water path 550. The purified water transported to the water tank 560 is transported to the second water inlet channel 230 of the faucet 100 via the second water extraction water path 540. The water in the first water inlet channel 220 and the second water inlet channel 230 is fully mixed in the mixing chamber and then transported to the user.

[0095] If the user does not open the mechanical valve 300, the newly prepared water by the booster pump 510 will completely flow into the water tank 560 to store water in the water tank 560. Since the flux of the water extraction pump 541 is much larger than that of the booster pump 510, during the process that the water extraction pump 541 pumps water from the water tank 560 and the booster pump 510 stores water in the water tank 560, the phenomenon of the water in the water tank 560 being full will not occur, and at the same time, the water extraction amount of the user from the water tank 560 by the water extraction pump 541 can be increased.

[0096] It can be seen from this that for the water purification system 500 with the above settings, on the one hand, when the user opens the mechanical valve 300 and the solenoid valve 400 simultaneously, two-way water supply can be carried out, thereby increasing the water extraction amount of the user per unit time. On the other hand, when the user only opens the solenoid valve 400, water will be pumped from the water tank 560 and water will be produced into the water tank 560 at the same time. Therefore, the time for the faucet 100 to discharge water at a larger flow rate is extended. These two aspects can both improve the user experience.

[0097] Furthermore, the system controller turns off the water extraction pump 541 when the solenoid valve 400 is closed. When the user closes the solenoid valve 400 through the faucet controller 440, the electromagnetic coil 430 will lose power. Without being attracted by the electromagnetic coil 430, the solenoid valve core 420 cuts off the second water inlet channel 230. At the same time, the system controller will turn off the water extraction pump 541 and stop the water extraction pump 541 from pumping water from the water tank 560.

[0098] In this way, it is avoided that the water pump 541 continues to work when the second water inlet channel 230 is cut off, which avoids the loss of the service life of the water pump 541 and saves the power consumption of the water purification system.

[0099] Exemplarily, a liquid level sensor 561 is provided on the water tank 560. The liquid level sensor 561 outputs a low liquid level signal when the liquid level in the water tank 560 is lower than the upper liquid level limit, and the system controller keeps the booster pump 510 and the water storage solenoid valve 551 open according to the low liquid level signal received from the liquid level sensor 561. It can be seen therefrom that after the water pump 541 starts to draw water from the water tank 560, the water in the water tank 560 will be lower than the upper liquid level limit, then the booster pump 510 and the water storage solenoid valve 551 are opened to store water in the water tank 560.

[0100] In this way, it can be ensured that after the user takes water from the water tank 560 each time, a water storage action will be performed on the water tank 560, and water can be stored in the water tank 560 in time, so that the user can obtain more water at a larger flow rate each time when taking water through the solenoid valve 400. At the same time, since water is stored in the water tank 560 as long as the solenoid valve 400 is opened, the water pump 541 can be prevented from idling.

[0101] Exemplarily, the liquid level sensor 561 outputs a high liquid level signal when the liquid level in the water tank 560 is higher than the upper liquid level limit, and the system controller closes the booster pump 510 and the water storage solenoid valve 551 when receiving the high liquid level signal.

[0102] In this way, it can be avoided that the water in the water tank 560 overflows due to too much water, affecting the user experience.

[0103] Exemplarily, the water purification system 500 further includes a pipeline machine interface 580, and the pipeline machine interface 580 is connected to the first water intake waterway 530 downstream of the high-pressure switch 532. The pipeline machine interface 580 can be connected to a pipeline machine, and the pipeline machine is connected in parallel with the first water inlet channel 220 of the faucet 100. The control method of the pipeline machine in the water purification system 500 is the same as that of the mechanical valve 300 of the faucet 100, and will not be elaborated here.

[0104] In this way, the usage range of the water purification system 500 can be expanded, making the applicable range of the water purification system 500 wider.

[0105] According to still another aspect of the present invention, a water temperature control system 600 is further provided, as Figure 4 shown, including any one of the faucets 100 described above. The water temperature control system 600 further includes a cold water pipeline 610, a hot water pipeline 620 and an operation panel 630. The first water inlet channel 220 is connected to one of the cold water pipeline 610 and the hot water pipeline 620, and the second water inlet channel 230 is connected to the other of the cold water pipeline 610 and the hot water pipeline 620.

[0106] A first temperature sensor 251 is arranged in the first water inlet channel 220 to detect the water temperature in the first water inlet channel 220 and output a first temperature signal. A second temperature sensor 252 is arranged in the second water inlet channel 230 to detect the second water temperature in the second water inlet channel and output a second temperature signal.

[0107] In one embodiment, the mechanical valve 300 controls the on-off of the first water inlet channel 220, which is connected to the cold water pipeline 610; the solenoid valve 400 controls the second water inlet channel 230, which is connected to the hot water pipeline 620. When the user sets the desired water temperature through the operation panel 630, the mechanical valve 300 and the solenoid valve 400 are opened simultaneously. The operation panel 630 will control the energization duration and / or power-off duration of the solenoid valve 400 in each cycle according to the collected first temperature signal and second temperature signal, so as to control the amount of hot water flowing into the mixing chamber 210 from the second water inlet channel 230. Ensure that the water temperature of the mixed water in the mixing chamber 210 is the temperature set by the user.

[0108] Alternatively, the first water inlet channel 220 can be connected to the hot water pipeline 620, and the second water inlet channel 230 can be connected to the cold water pipeline 610. By changing the amount of cold water entering the mixing chamber 210, the temperature of the water received by the user can be ensured.

[0109] It can be seen that for the water temperature control system 600 with the above structure, the user can accurately receive the water at the set temperature, reducing the manual control of the water temperature by the user and improving the user experience.
