At least a portion of the solenoid spool 420 is disposed within the second water inlet passage 230. in one embodiment, the solenoid spool 420 is a spool that is linearly movable within the second water inlet passage 230. The faucet manipulator 440 controls the movement of the solenoid valve spool 420 in response to a user's switch operation to control the on/off of the second water inlet passage 230.

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

Therefore, the faucet 100 has two water inlet channels which can be respectively communicated to two different water paths, the two water inlet channels are respectively controlled by the mechanical valve 300 and the electromagnetic valve 400, and are conveyed to a user through one water outlet channel after being mixed, so that the user can be prevented from installing two faucets at the same time, and the use space of the user is saved. In addition, the mixing chamber 210 is arranged between the water inlet channel and the water outlet channel of the faucet 100, so that water flows of two different water paths can be fully mixed in the mixing chamber 210, and the application range of the faucet 100 is enlarged. On this basis, the faucet 100 can directly control the water outlet of the faucet 100 through the mechanical handle 340, can also control the water outlet of the faucet 100 through the faucet controller 440, and can also control the water outlet of the faucet 100 through the mechanical handle 340 and the faucet controller 440, so that the application range of the faucet 100 is further expanded, and the faucet 100 can be adapted to more scenes.

Illustratively, the mechanical valve 300 further includes a mechanical valve seat 310 and a mechanical valve sleeve 320, the mechanical valve seat 310 being disposed on the first water inlet passage 220. The mechanical valve seat 310 may serve as a mounting base for the mechanical valve sleeve 320 and the mechanical valve core 330. One end of the mechanical valve housing 320 is connected to the mechanical valve seat 310, the mechanical valve spool 330 is disposed within the mechanical valve seat 310 and the mechanical valve housing 320, and the mechanical handle 340 is connected to the mechanical valve spool 330 at the other end of the mechanical valve housing 320. The mechanical valve core 330 can move with the mechanical handle 340 in the mechanical valve sleeve 320 to control the connection and disconnection of the first water inlet passage 220. The movement may be rotational or translational, as described above.

The mechanical valve 300 with the above structure has a simple structure and is convenient to install and maintain.

Illustratively, the solenoid valve 400 further includes a solenoid valve seat 410 and a solenoid 430, the solenoid valve seat 410 is disposed on the second water inlet passage 230, one end of the solenoid valve core 420 is disposed in the solenoid valve seat 410, and the solenoid 430 is disposed at the other end of the solenoid valve core 420, the solenoid 430 is connected to a faucet manipulator 440, the faucet manipulator 440 controls the energization state of the solenoid 430 in response to a user's switch operation, and the solenoid valve core 420 moves relative to the solenoid valve seat 410 when the energization state is changed to control the conduction/cutoff of the second water inlet passage 230.

In one embodiment, the solenoid valve seat 410 is a spool valve housing and the solenoid valve spool 420 is a spool valve spool that is linearly movable within the spool valve housing. A return spring is also normally provided in the spool housing and functions to provide the spool with a normal position, which is normally a position in which the water flow path is blocked. After the faucet manipulator 440 receives a faucet opening operation instruction from a user, the faucet manipulator 440 energizes the control electromagnetic coil 430 to generate a magnetic field, and counteracts the restoring force of the restoring spring under the action of the magnetic force to push the spool to move in the spool sleeve, so that the movement of the spool can turn on the second water inlet channel 230, thereby realizing the faucet water outlet. After the faucet manipulator 440 receives a faucet closing operation command from a user, the faucet manipulator 440 controls the electromagnetic coil 430 to lose power, the magnetic field disappears, and the slide valve core moves in the slide valve sleeve under the action of the reset force of the reset spring, so that the second water inlet channel 230 is cut off, and the faucet water closing is realized.

Accordingly, the solenoid valve 400 having this structure is simple in structure and easy to operate.

Illustratively, the faucet actuator 440 may be disposed on a top surface of the solenoid 430. The faucet actuator 440 is disposed on the same side of the faucet body 200 as the solenoid 430. Therefore, the faucet is compact in structure and small in occupied space.

Illustratively, the mixing chamber 210 has a decreasing size from bottom to top. In one embodiment, the mixing chamber 210 may be frustoconical in shape, as shown in FIG. 2.

Like this, rivers flow to the little one end of cross sectional area by the big one end of cross sectional area, and the velocity of flow will accelerate to collide the inner wall of hybrid chamber 210 and produce the vortex in hybrid chamber 210 at the flow in-process, and then can make the water in two inhalant canal mix in hybrid chamber 210 more fully.

Illustratively, under normal use of faucet 100, positioned as shown in FIG. 1, first inlet passage 220 and second inlet passage 230 extend in a vertical direction within faucet body 200. The mechanical valve seat 310 and the solenoid valve seat 410 are located on the side of the faucet body 200. The first axis of the mechanical spool 330 and the second axis of the solenoid spool 420 extend in a horizontal direction. And the first axis is perpendicular to the second axis. That is, the mechanical valve 300 and the solenoid valve 400 are arranged at a right angle when viewed from the top of the faucet 100 downward. The faucet actuator 440 may be disposed on a top surface of the solenoid 430.

This arrangement allows the mechanical valve 300 and the electromagnetic valve 400 to be distributed in different areas of the faucet body 200, and allows both the mechanical valve 300 and the electromagnetic valve 400 to face the direction of a user when the faucet 100 is installed, which facilitates the user's operation of both switches, while allowing the user to operate both the mechanical valve 300 and the electromagnetic valve 400 without interfering with each other. Also, the structure of the faucet 100 is more compact.

Illustratively, faucet 100 also 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 a first water temperature in the first water inlet passage 220 and output a first temperature signal. The second temperature sensor 252 is used for detecting a second water temperature in the second water inlet passage 230 and outputting a second temperature signal.

The control panel 900 includes an input device and a controller. The input device is used for receiving the set water temperature input by the user. The control panel 900 may control an opening time of the solenoid valve 400 based on the first and second temperature signals so that the temperature in the mixing chamber 210 reaches a set water temperature.

In one embodiment, the first water inlet passage 220 is connected with a cold water pipe, the second water inlet passage 230 is connected with a hot water pipe, and the mechanical valve 300 controls the on-off of the first water inlet passage 220, and cold water (namely normal temperature water) flows in the first water inlet passage; the solenoid valve 400 controls the second water inlet passage 230, in which hot water circulates. When the user inputs the desired water temperature on the input device, the mechanical valve 300 and the electromagnetic valve 400 are simultaneously opened, and the controller controls the opening time of the electromagnetic valve 400 according to the collected first temperature signal and the second temperature signal. If the solenoid valve 400 is opened for a long time, the water temperature in the mixing chamber 210 is high; if the solenoid valve 400 is opened for a short time, the temperature of the water in the mixing chamber 210 is low.

Alternatively, the first water inlet passage 220 may be connected to a hot water pipe through which hot water flows, and the second water inlet passage 230 is connected to a cold water pipe through which cold water flows, in the same manner.

Therefore, the faucet 100 with the structure can realize the allocation of water with different temperatures in the mixing cavity 210 according to the water temperature set by the user, and realize instant heating, thereby reducing the manual regulation and control of the user on the water temperature and improving the use experience of the user.

Further, the controller may control the energization period and/or the deenergization period 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 with a cold water pipe, the second water inlet passage 230 is connected with a hot water pipe, and the mechanical valve 300 controls the on-off of the first water inlet passage 220, and cold water (namely normal temperature water) flows in the first water inlet passage; the solenoid valve 400 controls the second water inlet passage 230, in which hot water circulates. When the user inputs the desired water temperature on the input device, and simultaneously opens the mechanical valve 300 and the electromagnetic valve 400, the controller can cause the second water inlet channel 230 controlled by the electromagnetic valve 400 to deliver water into the mixing chamber 210 in a pulse manner according to the collected first temperature signal and second temperature signal.

For example, the controller may control the temperature of the water obtained by the user by varying the duration of the solenoid valve 400 being energized, while the duration of the solenoid valve being de-energized, to adjust the amount of hot water delivered to the mixing chamber 210 during each cycle. One power-on and one power-off constitute one cycle. For example, the controller may also control the temperature of the water obtained by the user by varying the amount of cold water delivered to the mixing chamber 210 during each cycle by varying the duration of the solenoid valve 400 that is de-energized, while the duration of the solenoid valve is not energized. For example, the controller may vary the power-on duration and the power-off duration of the solenoid valve 400 at the same time to control the temperature of the water taken by the user. In this case, the time period of each cycle may be fixed, for example, when the water temperature obtained when the power-on time period and the power-off time period are both 2 seconds is lower than the temperature set by the user, the power-on time period may be extended and the power-off time period may be shortened, for example, the power-on time period may be set to 3 seconds and the power-off time period may be set to 1 second, thereby increasing the water temperature in the mixing chamber 210.

Alternatively, the first water inlet passage 220 may be connected to a hot water pipe through which hot water circulates, and the second water inlet passage 230 is connected to a cold water pipe through which cold water circulates. The cold water is delivered to the mixing chamber 210 in a pulse manner at a predetermined cycle, and the temperature of the water in the mixing chamber 210 can be set to a water temperature set by a user. The control of the cycle by the controller is the same as in the above embodiment.

Therefore, the faucet 100 with the above structure can automatically mix water with different temperatures in the mixing cavity 210 more accurately according to the water temperature set by the user, and improves the user experience.

Illustratively, the faucet manipulator 440 may be integrated into the control panel 900. In this way, the degree of integration of the faucet 100 can be increased, and the size of the faucet 100 can be reduced. Also, the faucet 100 is modular, which can reduce the cost of the faucet 100.

Illustratively, 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 temperature of the water in the first inlet channel 220, the temperature of the water in the second inlet channel 230, and/or the user's set water temperature via the display 930.

Therefore, the user can conveniently and accurately know the water temperature condition in the current water path and the set water temperature condition of the faucet 100 in time.

In the existing water purification system, a water storage electromagnetic valve and a water suction pump are generally connected in series on a water storage pipeline, and a water storage stage to a water tank and a water suction stage from the water tank are completed through the water storage pipeline. As is well known to those skilled in the art, the back pressure of the water storage solenoid valve cannot exceed 0.05MPa under normal operation, while the back pressure of the pipeline in which the water storage solenoid valve is located in the conventional water purification system usually exceeds 0.25MPa or more. Therefore, the water storage electromagnetic valve can not work normally. This results in the electrically controlled faucet having sent a water intake signal and the suction pump having begun to take water from the tank, but the reservoir solenoid valve is inoperable due to the high back pressure, thereby not opening the reservoir line. Therefore, a user cannot take water, and the water pump pumps water under the condition that the outlet is blocked, so that the service life of the water pump is shortened for a long time. And if the end of fetching water is communicating pipeline machine to the user heats the water that will flow through pipeline machine, then pipeline machine sends the water intaking signal after, if when the same condition takes place, pipeline machine will dry under the condition that does not have water burn, very easily produces danger.

In order to avoid the above situation, according to another aspect of the present invention, there is provided a water purification system 500, as shown in fig. 3, comprising a booster pump 510 and a reverse osmosis filter element 520 connected to a water outlet of the booster pump 510. The booster pump 510 is used for pressing raw water into the reverse osmosis filter element 520, and discharging filtered pure water from a pure water outlet of the reverse osmosis filter element under the action of the reverse osmosis filter element. The operation of the reverse osmosis cartridge 520 is well known to those skilled in the art and will not be described in detail.

The water purification system 500 further comprises any of the faucets 100 described above. In addition, the water purification system 500 further includes a first water intake waterway 530, a second water intake waterway 540, a water storage waterway 550, and a water tank 560.

One end of the first water intake waterway 530 is communicated to the pure water port 521 of the reverse osmosis filter element 520, the other end of the first water intake waterway 530 is communicated to the first water intake channel 220 of the faucet 100, and a check valve 531 and a high-pressure switch 532 are sequentially arranged on the first water intake waterway 530 along the water flow direction.

One end of the second water intake waterway 540 is connected to the water tank 560, the other end of the second water intake waterway 540 is connected to the second water inlet channel 230 of the faucet 100, and a suction pump 541 is disposed on the second water intake waterway 540.

One end of the water storage path 550 is connected to the water tank 560, the other end of the water storage path 550 is connected to the first water intake path 530 at the downstream of the high voltage switch 532, and the water storage path 550 is provided with a water storage solenoid valve 551.

When a user moves the mechanical valve core 330 through the mechanical handle 340, the mechanical valve 300 will make the first water inlet passage 220 conducted, so that the first water inlet passage 220 to the check valve 531 on the first water taking waterway 530 will be conducted to the atmosphere, the pressure will be reduced, the high-pressure switch 532 will be closed (triggered) after the high-pressure switch 532 detects the pressure reduction, and the booster pump 510 will start and start to pump water into the reverse osmosis filter element 520 after receiving the electric signal of the closed high-pressure switch 532. The pure water flows to the first water intake passage 220 through the first water intake waterway 530, and is finally taken by the user.

When the user closes the first water inlet channel 220 by operating the mechanical valve 300, the booster pump 510 continues to produce water to the first water taking waterway 530 until the pressure in the first water taking waterway 530 exceeds the set value of the high-pressure switch 532, the high-pressure switch 532 is turned off, the booster pump 510 stops producing water after receiving the electric signal generated by turning off the high-pressure switch 532, and at this time, the first water taking waterway 530 is kept at a high pressure under the action of the check valve 531, and the water purification system 500 enters a standby state.

When the user opens the solenoid valve 400 via the faucet actuator 440, the solenoid 430 is energized and generates a magnetic field that moves the solenoid valve cartridge 420 and conducts the second water inlet channel 230. Meanwhile, the water pump 541 will also receive the electrical signal for getting water from the faucet manipulator 440 and start the water pump 541. The suction pump 541 draws the prepared pure water from the water tank 560 to be discharged from the faucet 100 through the second water inlet passage 230.

When the user operates the faucet manipulator 440 to close the solenoid valve 400, the solenoid 430 is de-energized, the magnetic field disappears, the solenoid valve core 420 returns to the original position, and the second water inlet passage 230 is closed. Meanwhile, the water pump 541 also stops the water pump 541 upon receiving the water intake stop signal from the faucet controller 440. The water purification system 500 enters a standby state.

That is, whether the user opens the mechanical valve 300 or the solenoid valve 400, the high-pressure switch 532 is triggered, the booster pump 510 is activated, and the reverse osmosis filter 520 starts to produce water.

Since the second water intake waterway 540 communicates with the water tank 560, it is necessary to ensure that the prepared pure water is stored in the water tank 560 in advance. There are various methods of detecting the amount of water stored in the water tank 560, and a weight detecting means may be provided in the water tank 560 to determine the amount of water in the water tank by detecting the weight of the water tank. A preferred embodiment will also be provided below.

When the water storage solenoid valve 551 receives that the amount of water in the water tank 560 is lower than a predetermined value, the water storage solenoid valve 551 is opened. The water storage solenoid valve 551 has an on state and an off state. When the water storage solenoid valve 551 is turned on, the first water intake path 530, the water storage path 550, and the water tank 560 are communicated, and the pressure of the first water intake path 530 is reduced. When the high-pressure switch 532 detects that the pressure is reduced, the high-pressure switch 532 is closed, and the booster pump 510 starts to pump water into the reverse osmosis filter element 520 after receiving an electric signal indicating that the high-pressure switch 532 is closed. The pure water passes through the check valve 531, the first water intake waterway 530, the water storage waterway 550, and finally enters the water tank 560.

Until the water tank 560 is filled with water, the water storage solenoid valve 551 closes the water storage path 550. At this time, the booster pump 510 continues to produce water into the first water taking waterway 530 until the pressure in the first water taking waterway 530 exceeds the set value of the high-voltage switch 532, the high-voltage switch 532 is turned off, and the booster pump 510 stops producing water after receiving the electric signal generated by turning off the high-voltage switch 532, at this time, the first water taking waterway 530 is kept at a high pressure under the action of the check valve 531, and the water purifying system 500 enters a standby state.

Therefore, the second water taking water channel 540 connected with the electromagnetic valve 400 and the water storage water channel 550 are separately arranged, so that the situation that a user cannot take water due to the fact that the water taking end sends a water taking signal and the back pressure of the pipeline where the water storage electromagnetic valve 551 is located cannot be timely conducted can be effectively avoided.

Illustratively, the water purification system 500 includes a system controller connected to the faucet manipulator 440 that turns on the booster pump 510, the suction pump 541, and the water storage solenoid valve 551 with the solenoid valve 400 open. Specifically, when the user takes water from the faucet actuator 440, the solenoid 430 is turned from off to on, and the system controller will turn on the booster pump 510, the suction pump 541, and the water storage solenoid 551. And a system controller is connected to the high voltage switch 532, the system controller turns on the booster pump 510 if the high voltage switch 532 is triggered.

The case where one of the mechanical valve 300 and the solenoid valve 400 is opened may refer to the description of the corresponding parts above. When the mechanical valve 300 and the solenoid valve 400 are opened simultaneously, the water produced by the booster pump 510 can be delivered to the first water inlet channel 220 of the faucet 100 through the first water intake waterway 530 and can also be delivered to the water tank 560 through the water storage waterway 550. The pure water supplied to the water tank 560 is supplied to the second water inlet passage 230 of the faucet 100 via the second water taking waterway 540. The water in the first water inlet passage 220 and the water in the second water inlet passage 230 are fully mixed in the mixing cavity and then delivered to the user.

And if the user does not open the mechanical valve 300, the freshly prepared water of the booster pump 510 will completely flow into the water tank 560 to store the water in the water tank 560. Since the flux of the water pump 541 is much larger than the flux of the booster pump 510, when the water pump 541 pumps water from the water tank 560 and the booster pump 510 pumps water into the water tank 560, the water tank 560 is not full of water, and the amount of water pumped from the water tank 560 by the user through the water pump 541 can be increased.

It can be seen that, with the water purification system 500 configured as above, on one hand, when the user opens the mechanical valve 300 and the electromagnetic valve 400 at the same time, two-way water supply is possible, thereby increasing the water intake per unit time of the user, and on the other hand, when the user opens only the electromagnetic valve 400, water is pumped from the water tank 560 into the water tank 560 at the same time, thereby prolonging the time for the faucet 100 to discharge water at a large flow rate. In both aspects, the user experience can be improved.

Further, the system controller closes the suction pump 541 with the solenoid valve 400 closed. When the user closes the solenoid valve 400 through the faucet controller 440, the solenoid 430 loses power, the solenoid valve core 420 is not attracted by the solenoid 430, the second water inlet passage 230 is closed, and the system controller turns off the water pump 541 to stop the water pump 541 from pumping water from the water tank 560.

In this way, the water pump 541 is prevented from continuously operating when the second water inlet passage 230 is cut off, the life of the water pump 541 is prevented from being lost, and the power consumption of the water purification system is saved.

Illustratively, a level sensor 561 is disposed 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 pressurizing pump 510 and the water storage solenoid valve 551 on according to the low liquid level signal received from the liquid level sensor 561. It can be seen that when the water pump 541 is started to pump water from the water tank 560, the water in the water tank 560 is lower than the upper limit of the liquid level, and then the pressurizing pump 510 and the water storage solenoid valve 551 are opened to store water into the water tank 560.

Thus, the user can be guaranteed to carry out water storage action on the water tank 560 after taking water from the water tank 560 every time, water can be stored in the water tank 560 in time, and the user can obtain more water at a larger flow rate when taking water through the electromagnetic valve 400 every time. Meanwhile, since water is stored in the water tank 560 by only opening the solenoid valve 400, the idle rotation of the suction pump 541 can be prevented.

Illustratively, the level sensor 561 outputs a high level signal when the liquid level within the tank 560 is above an upper liquid level limit, and the system controller turns off the booster pump 510 and the water storage solenoid valve 551 if the high level signal is received.

In this way, it is avoided that the water in the water tank 560 is excessive and overflows, affecting the user experience.

Illustratively, the water purification system 500 further includes a line machine interface 580, the line machine interface 580 being communicated to the first water intake waterway 530 downstream of the high pressure switch 532. The line machine interface 580 may be connected to a line machine that is connected in parallel with the first water inlet passage 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 thus the detailed description thereof is omitted.

Thus, the application range of the water purification system 500 can be expanded, and the application range of the water purification system 500 is wider.

According to yet another aspect of the present invention, there is also provided a water temperature regulating system 600, as shown in FIG. 4, comprising any of the faucets 100 described above. The water temperature regulation system 600 further includes a cold water line 610, a hot water line 620, and an operation panel 630. The first water inlet passage 220 communicates with one of the cold water pipe 610 and the hot water pipe 620, and the second water inlet passage 230 communicates with the other of the cold water pipe 610 and the hot water pipe 620.

A first temperature sensor 251 is disposed in the first water inlet channel 220, and is used for detecting the temperature of water in the first water inlet channel 220 and outputting a first temperature signal. A second temperature sensor 252 is disposed in the second water inlet passage 230 for detecting a second water temperature in the second water inlet passage and outputting a second temperature signal.

In one embodiment, the mechanical valve 300 controls the on/off of the first water inlet passage 220, which is communicated with the cold water pipeline 610; the solenoid valve 400 controls the second water inlet passage 230, which communicates with the hot water line 620. When the user sets the desired water temperature through the operation panel 630, the mechanical valve 300 and the solenoid valve 400 are simultaneously opened, and the operation panel 630 controls the power-on duration and/or the power-off duration of the solenoid valve 400 in each period according to the collected first temperature signal and the collected second temperature signal, so as to control the amount of hot water flowing into the mixing chamber 210 from the second water inlet passage 230. It is ensured that the temperature of the mixed water in the mixing chamber 210 is the temperature set by the user.

The first water inlet passage 220 may be connected to the hot water pipe 620, the second water inlet passage 230 may be connected to the cold water pipe 610, and the temperature of the water received by the user may be ensured by changing the amount of the cold water entering the mixing chamber 210.

Therefore, the water temperature regulating system 600 with the structure has the advantages that the user can accurately access water with the set temperature, the manual regulation and control of the user on the water temperature are reduced, and the use experience of the user is improved.
