A control method of the water supply system according to the embodiment of the present invention will be described with reference to fig. 25 and 26. The execution main body of the method can be a controller in a water supply system, or a cloud terminal, or an edge server.

A water purifier, which is a water treatment apparatus that performs processes such as filtration, purification, and heating of water according to the use requirements of users for water, and a faucet constitute a water supply system.

The water purifier has water inlet connected to the external water supply network, water outlet 111 connected to the water inlet of the water tap, water from the external water supply network being treated and conveyed to the water tap, and water outlet 111 for the user to take water.

The water supply system is provided with an electromagnetic valve which is an automatic element for controlling fluid and can adjust the direction, flow, speed and other parameters of water in the water inlet and outlet pipeline.

The electromagnetic valve in the water supply system is arranged between the water outlet 111 of the water purifier and the water outlet 111 of the water faucet, and the water outlet of the water outlet 111 of the water faucet is started and stopped by controlling the opening and closing of the electromagnetic valve.

In actual implementation, the electromagnetic valve may be disposed inside the water purifier or inside the faucet, and both the electromagnetic valve and the faucet can control the water outlet of the faucet water outlet 111 to start and stop.

An electromagnetic valve is arranged between the water outlet 111 of the water purifier and the water outlet 111 of the water faucet, a mechanical valve arranged in the water faucet in the related art is omitted, and the water supply system is controlled electrically through the electromagnetic valve.

As shown in fig. 25, the control method of the water supply system includes steps 2510 to 2520.

Step 2510, a first input is received from a user turning the handle of the faucet in a first direction.

When the water tap is in a water cut-off state, a user operates the handle on the water tap to rotate towards a first direction and rotate to a first target position, the first sensor 430 in the handle generates a corresponding electric control signal, and the water supply system receives a first input.

The first input is a control instruction input by rotating a faucet handle, and the first input can control the water outlet start and stop, the water outlet temperature and the water outlet amount in the water supply system.

Wherein, after the handle rotated first target position to the first direction, the elastic force that elastic component 360 in the handle produced for the handle resets to initial position, need not the user and carries out the operation that the handle resets, has overcome prior art, and control handle rotates the back, needs the defect that the user operation handle resets, simplifies tap water intaking process.

In actual implementation, taking the faucet located at the front of the user as an example, the first direction may be a direction in which the user operates the handle to dial backwards, that is, a direction away from the user; the first direction may also be a direction in which the user operates the handle to dial forward, i.e. a direction close to the user.

And 2520, responding to the first input, controlling the water purifier to produce water and opening the electromagnetic valve to enable the water outlet 111 of the water faucet to discharge water.

In this embodiment, the action of controlling the faucet to start and stop the water outlet is performed in response to a first input, which may be a control command in the water supply system, or in some embodiments, a control command for controlling the temperature of the outlet water or the amount of the outlet water.

The water supply system responds to the first input and controls the solenoid valve to open and the faucet to discharge water for use by a user.

In the embodiment, the water purifier is controlled to start water production in response to the first input, and the water production process of the water purifier mainly performs purification treatment on water from a water supply network, and mainly comprises the steps of removing solid impurities, removing chlorine, removing metal particles and the like.

The water production mode of the water purifier is a mode in which a user sets the effluent water temperature, the effluent water quality, the purified water level and other water treatment standards on the water supply system before receiving the first input of the handle.

In this embodiment, after receiving the first input from the handle, in response to the first input, the water purifier starts to produce water according to the set water production mode, and at the same time, the solenoid valve is controlled to open to communicate the water leaching pipeline between the faucet and the water purifier, so that the water produced by the water purifier flows out from the faucet water outlet 111 for the user to use.

According to the control method of the water supply system provided by the embodiment of the invention, the water outlet start-stop of the faucet is controlled by rotating the handle to the first direction, the handle can be automatically reset through the elastic piece 360 after rotating, the handle reset operation is not required by a user, the water taking process is more convenient and faster, the electromagnetic valve is arranged in the water supply system, and the water outlet start-stop is controlled through the electromagnetic valve, so that the intelligent control of the water supply system is realized.

In some embodiments, after receiving the first input, further determining whether to control the opening of the electromagnetic valve according to a water production mode currently set by the water supply system.

The target temperature is the temperature of the set safe water and is also a scald-preventing water temperature limit, and the water temperature is lower than the target temperature, so that the scald condition can not occur when a user uses the water heater; the water with the temperature above the target temperature can cause scalding when being used by a user. The target temperature may be 45 degrees celsius or 50 degrees celsius, or may be set by the user as required.

In actual implementation, the target temperature may be 45 degrees celsius or 50 degrees celsius, or may be set by a user according to a requirement.

Take the water making mode currently set by the user as 80 ℃ hot water making as an example.

The set outlet water temperature of 80 ℃ is higher than the target temperature of 45 ℃, and after the user operates the handle to rotate to the first target position in the first direction, whether the electromagnetic valve is controlled to be opened or not needs to be judged according to the received stay time of the first input.

The first target time length is used as a time length judgment standard for controlling the water outlet of the water outlet 111, and the first input is divided into a first input that the stay time length of the handle at the first target position does not exceed the first target time length and a first input that the stay time length exceeds the first target time length.

In actual execution, after the user operation handle is rotated to a first target position in a first direction, the operation that the stay time length does not exceed the first target time length is called short dialing; an operation in which the stay time of the handle exceeds the first target time period is called long dialing.

It can be understood that the stay time after the handle is rotated to the first target position in the first direction is different, the received first input is different, and whether to control the water outlet 111 of the faucet to discharge water is judged according to the different first inputs and the difference between the current water outlet temperature set by the faucet and the target temperature.

The water outlet temperature set at present is higher than the target temperature, the handle rotates to the first target position in the first direction, the time length kept at the first target position is shorter than the first target time length, the control electromagnetic valve is closed, the water outlet 111 of the water faucet does not discharge water, the water with the temperature higher than the target temperature cannot directly flow out, and the user is prevented from being scalded.

That is to say, under the condition that the present leaving water temperature that sets for is higher than the target temperature, the user dials the unable control solenoid valve of handle for a short time and opens, and tap delivery port 111 goes out water, can effectively avoid the condition that the user is scalded to take place.

For example, the water outlet temperature set by the first user is 90 ℃ and is used for cooking, at this time, the second user is ready to wash hands with water, the second user dials the handle for a short time, the water outlet 111 of the faucet cannot be controlled, and the second user is prevented from being scalded by hot water at 90 ℃.

In actual implementation, the current set outlet water temperature and the prompt for the user to dial the handle for outlet water may be displayed on the display 450 of the faucet.

In some embodiments, when the water outlet temperature set by the user is not higher than the target temperature, the time for which the handle is operated by the user at the first target position is shorter than the first target time, the control solenoid valve is opened, and the water faucet discharges water.

The water outlet temperature set by the user is not higher than the target temperature, the handle rotates to the first target position in the first direction, the time length of the handle kept at the first target position is shorter than the first target time length, the electromagnetic valve is controlled to be opened, the water outlet 111 of the faucet discharges water, and at the moment, the temperature of the water flowing out after the water is discharged from the faucet is below the target temperature, so that the water can directly flow out, and the user cannot be scalded.

That is to say, under the condition that the outlet water temperature that tap set for at present is not higher than the target temperature, the user dials the handle for a short time and just can control tap delivery port 111 and go out water, and handle accessible elastic component 360 automatic re-setting need not the user and has reset manually, has simplified user's water intaking process.

In some embodiments, the user sets the outlet water temperature to be higher than the target temperature, the user operates the handle at the first target position for a period of time not shorter than the first target period of time, the water purifier is controlled to produce water according to the current water production mode, and the electromagnetic valve is controlled to be opened, so that the faucet outputs water for the user to use.

For example, the user can set the water outlet temperature to be 90 ℃ for cooking, and after the setting is finished, the handle is directly pulled for a long time to control the water outlet of the water faucet, so that the user can take water.

The first input that the stay time of the handle after the first target position is not shorter than the first target time is an input instruction for directly controlling the water outlet of the faucet.

The user can realize that the control solenoid valve begins under the different circumstances of tap temperature of intaking through dialling the handle for a long time, and tap delivery port 111 goes out water, has practiced thrift the temperature regulation process when intaking to 360 automatic re-setting of handle accessible elastic component need not manual reset.

In some embodiments, the current outlet water temperature of the faucet is higher than the target temperature, the time for which the handle is kept at the first target position is shorter than the first target time, the water outlet 111 of the faucet is controlled to be cut off, the water with the temperature higher than the target temperature cannot directly flow out, and the reminding information is displayed on the display screen 450 of the faucet.

The display screen 450 may display a prompt message including a current faucet water temperature value and a prompt for the long dial handle to control the water outlet.

The user can carry out the operation of adjusting the temperature according to the reminding information of the display screen 450, and then short dials the handle, controls the water outlet 111 of the tap, and long dials the handle, controls the tap to discharge water.

In some embodiments, the faucet is currently out of water at a temperature above the target temperature, the handle is held in the first target position for a period of time shorter than the first target period of time, the faucet outlet 111 is controlled to cut off water, water at a temperature above the target temperature does not flow out directly, and the faucet's breathing light 460 is controlled to blink in a target manner.

The breathing lamp 460 of the faucet flashes in a targeted manner, which can remind the user that the water outlet temperature of the faucet is higher than the targeted temperature, possibly causing scalding.

In the embodiment of the invention, the breathing lamp 460 is in a flashing reminding mode in a target mode, so that the method is more convenient and faster, and a user can receive a danger prompt without checking the current water outlet temperature of the faucet.

In actual implementation, the faucet's breathing light 460 blinks in a targeted manner, wherein the targeted manner may be expressed as at least one of: target blinking color, target blinking interval, target blinking brightness, and the like.

First, the faucet's breathing light 460 flashes in a target flashing color, including, but not limited to, red, yellow, green, and the like.

In this embodiment, the current outlet water temperature of the faucet is higher than the target temperature, the time for which the handle is kept at the first target position is shorter than the first target time, the outlet 111 of the faucet is controlled to cut off water, and the breathing lamp 460 of the faucet is controlled to flash with the target flashing color to remind the user that the current outlet water temperature of the faucet is higher than the target temperature, which may cause scald.

Second, the breathing light 460 of the faucet blinks at the target blinking interval.

In this embodiment, the control faucet water outlet 111 is cut off and the control faucet breathing light 460 may flash at a flashing frequency of 4 times per second to alert the user.

Third, the faucet's breathing light 460 blinks at the target blinking intensity.

In this embodiment, the breathing lamp 460 of the faucet in the standby state flashes at a lower brightness, when the current outlet water temperature of the faucet is higher than the target temperature, the time period for which the handle is kept at the first target position is shorter than the first target time period, and when the water outlet 111 of the faucet is controlled to cut off, the breathing lamp 460 of the faucet is controlled to flash at a higher brightness to remind the user.

Of course, in other embodiments, the target blinking manner of the breathing lamp 460 may also be represented in other forms, which may be determined according to actual needs, and this is not limited in this application.

In some embodiments, the handle is operated to rotate in a second direction, and the water supply system receives a second input from the handle to control the outlet water temperature.

The handle on the faucet can rotate towards different directions, and the handle rotates towards a first direction to reach a first target position and rotates towards a second direction to reach a second target position.

It can be understood that the handle can be reset by the elastic force of the elastic member 360 in the handle after rotating the handle in the first direction to the first target position and rotating the handle in the second direction to the second target position.

When the handle rotates to the first target position in the first direction and rotates to the second target position in the second direction, the first sensor 430 on the handle can generate different electric control signals, and the generated first input and the second input are instructions capable of controlling the actions of starting and stopping the water outlet of the water supply system, the water outlet temperature, the water outlet amount and the like.

For example, the handle rotates to a first target position in a first direction, and the handle corresponds to a first input to control the water outlet start and stop of the faucet; the handle rotates to a second target position towards a second direction, and the handle corresponds to a second input and is used for controlling the water outlet temperature of the faucet.

In an actual implementation, taking the faucet located at the front of the user as an example, the first direction may be a direction in which the user operates the handle to dial backwards, that is, a direction away from the user, and at this time, the second direction may be a direction in which the user operates the handle to dial forwards, that is, a direction close to the user.

In some embodiments, after receiving the second input from the handle, the adjustment of the outlet water temperature is controlled differently according to the length of time the handle stays at the second target position.

It can be understood that the corresponding temperature module is arranged in the water supply system, and the water flowing out of the water outlet 111 can be heated or cooled according to the adjusted outlet water temperature gear, so that the water temperature of the water flowing out of the water outlet 111 is consistent with the adjusted outlet water temperature gear.

In response to the second input, the water outlet temperature gear of the faucet can be continuously shifted or shifted for a single time.

The continuous gear shifting refers to a continuous and uninterrupted gear shifting process performed on the outlet water temperature gear, for example, the first gear to the second gear, the second gear to the third gear, and the continuous gear shifting is performed sequentially until the input is finished.

The single gear shifting refers to single gear shifting performed by a water yield gear, and the single gear shifting is input to adjust one water outlet temperature gear each time, for example, the water outlet temperature gear is shifted from a first gear to a second gear, and the current gear shifting is finished.

Taking the example that the current water outlet temperature is 20 ℃ and the temperature is adjusted at each time is 10 ℃.

The continuous gear shifting refers to adjusting the water outlet temperature from 20 ℃ to 30 ℃, adjusting the temperature from 30 ℃ to 40 ℃, and sequentially and continuously shifting until the input is finished; the single gear shifting refers to that the gear of the water outlet temperature is adjusted from 20 ℃ to 30 ℃, and the gear shifting is finished.

In this embodiment, the adjustment of the outlet temperature steps can be set to the circulation mode, for example, the outlet temperature range is 45 degrees celsius to 95 degrees celsius, the temperature step for each adjustment is 10 degrees celsius, and the adjusted outlet temperature steps are 45 degrees celsius, 55 degrees celsius, 65 degrees celsius, 75 degrees celsius, 85 degrees celsius, and 95 degrees celsius, respectively.

It can be understood that what degree of centigrade each time the temperature gear is adjusted can be set by the user according to the requirement, for example, the temperature gear each time the adjustment is adjusted can be set to 5 degrees centigrade, and also can be set to 10 degrees centigrade.

And the adjustment of the water outlet temperature gear can be to increase the water outlet temperature of the faucet by up-regulation or to decrease the water outlet temperature of the faucet by down-regulation.

The second target time length is a judgment standard for controlling the water outlet temperature to perform continuous gear shifting or single gear shifting, the time length of the handle kept at the second target position is shorter than the second target time length, the water outlet temperature of the faucet is controlled to perform single gear shifting, and a currently set water outlet temperature gear can be displayed on the display screen 450.

And the user operates the handle to rotate towards the second direction to reach the second target position and stay for a time shorter than the second target time, single gear shifting of the water outlet temperature gear is carried out, the water outlet temperature gear is shifted up by 10 ℃, and the water temperature gear displayed on the display screen 450 is 30 ℃.

In this embodiment, the outlet water temperature may be adjusted down by 10 degrees celsius, and the display screen 450 displays that the water temperature is 10 degrees celsius.

In actual execution, after the user operation handle is rotated to a second target position in a second direction, the stay time length does not exceed the second target time length, which is called short dialing; an operation in which the handle stay time period exceeds the second target time period is called long dialing.

In some embodiments, the handle controls the faucet to continuously shift the outlet water temperature when the duration of the second target position is not shorter than the duration of the second target position.

In the embodiment, the time length of the handle at the second target position is not shorter than the second target time length, the time length exceeding the second target time length is calculated, and the gear of the outlet water temperature is continuously adjusted step by taking the first target time interval as a standard until the handle leaves the second target position.

The first target time interval is a time standard of continuous gear shifting of the water outlet temperature gear, the water outlet temperature gear is adjusted by one gear every time when the time of the handle at the second target position exceeds the time of the second target position, and the adjustment of the water outlet temperature gear is stopped when the handle leaves the target position.

It will be appreciated that the first target time interval and the second target time duration and the temperature steps to be adjusted each time can be set as desired.

Take a target time duration of 3 seconds and a target time interval of 1 second as an example.

When the current water temperature gear is 20 ℃, the stay time of the handle at the second target position exceeds 3 seconds, the water temperature gear is adjusted step by step, when the water temperature gear is adjusted to be 30 ℃ in the 4 th second, when the water temperature gear is adjusted to be 5 seconds, the gear is adjusted upwards, the water temperature gear is adjusted to be 40 ℃, and when the handle leaves the second target position, the gear adjustment is stopped.

It can be understood that the adjustment process of the outlet water temperature gear can be displayed on the display screen 450, and the user can adjust the outlet water temperature gear according to the current outlet water temperature gear displayed on the display screen 450 to stop the continuous gear shifting of the outlet water temperature gear.

It is worth noting that the handle rotates and stays towards the second direction for controlling the water outlet temperature gear of the faucet, and after the water outlet temperature gear is set by a user, the user needs to operate the handle again to rotate and stay towards the first direction to control the corresponding water purifier to produce water and the electromagnetic valve to be opened, so that the faucet can flow water with the set temperature.

In some embodiments, the faucet is currently in a standby state, a temperature display input is received from a user turning the handle in a second direction, and a tap position of the current leaving water temperature is displayed on the faucet display screen 450 in response to the temperature display input.

In this embodiment, the faucet is currently in a standby state, and at this time, the user turns the handle in the second direction for the first time, which is an input instruction for displaying the current outlet water temperature gear.

In response to the temperature display input, the current water outlet temperature gear is displayed on the faucet display screen 450, and a user can judge whether to take water or not according to the current water outlet temperature gear displayed on the faucet display screen 450, or need to adjust the water outlet temperature gear and then take water for use.

It can be understood that after receiving the temperature display input that the user rotates the handle in the second direction, the user rotates the handle in the second direction again, and at this time, the second input for adjusting the water temperature gear is received.

In specific implementation, the current outlet water temperature gear can be the lowest outlet water temperature gear, and can also be the outlet water temperature gear set when the faucet is shut down last time.

The lowest gear of the outlet water temperature can be set according to the water using environment or the environment temperature of a user.

For example, in a kitchen water environment, the user fetches water mainly for washing vegetables or cooking, at this time, the lowest gear can be set to 20 degrees centigrade, and the user can directly fetch water for use after looking over the water temperature gear on the display screen 450.

In bathroom water environment, user's water intaking mainly used bathes or washes hands, at this moment, can set up minimum gear into 40 degrees centigrade, and the user looks over behind the leaving water temperature gear at display screen 450, and the direct water intaking of being convenient for is used, practices thrift the time of adjusting the temperature, makes the water intaking process more convenient.

When current ambient temperature is lower, can suitably improve the minimum gear of leaving water temperature, practice thrift the time of adjusting the temperature, the user can directly get the water and use.

The current outlet water temperature gear can be the outlet water temperature gear when the faucet was shut down last time, for example, when the faucet was shut down last time, the outlet water temperature gear that the user set for was 50 degrees centigrade, can be after the user interrupted the use, does not change the outlet water temperature gear that sets for, when the user was started the use once more, received the temperature and showed that the current outlet water temperature gear was 50 degrees centigrade, and the user of being convenient for directly gets the water and continues to use.

In some embodiments, a third input from the user to the first sensor 440 on the handle is received, and the water output of the faucet is adjusted in response to the third input.

The first sensor 440 may be a light sensing button, and the light sensing signal is used to collect a pressing operation intention of the user and receive a third input from the user to the first sensor 440.

The expression form of the third input of the first sensor 440 by the user may be that the user touches the first sensor 440, and the first sensor 440 collects the operation intention of the user, generates a corresponding electric control signal, and transmits the electric control signal to the controller of the faucet.

The first sensor 440 can operate in a water environment without obstacles, and a user can enable the water supply system to receive the third input by only touching the first sensor 440, so that the operation process does not cause the faucet to shake greatly.

It can be understood that the water outlet control of the faucet can be realized by opening and closing the electromagnetic valve, and in specific implementation, the volume flow can be calculated according to the current flow rate, and the opening and closing time of the electric control valve in the water outlet pipeline can be controlled, so that the quantitative water outlet of the faucet can be realized.

In response to a third input, a continuous shift or a single shift of the water output level of the faucet may be made.

The continuous shift refers to a continuous and uninterrupted shift process performed on the water yield gear, for example, the first gear to the second gear, the second gear to the third gear, and the continuous shift is performed sequentially until the input is finished.

The single gear shifting refers to single gear shifting performed by the water yield gear, and the single gear shifting is performed by inputting the water yield gear to adjust one water yield gear each time, for example, the water yield gear is shifted from the first gear to the second gear, and the current gear shifting is finished.

Take the currently set water yield of 500 ml and the quantitative gear of 200 ml for each adjustment as an example.

The continuous gear shifting refers to adjusting the water yield from 500 ml to 700 ml and 700 ml to 900 ml, and sequentially and continuously shifting until the input is finished; the single gear shifting refers to that the water yield gear is adjusted from 500 ml to 700 ml, and the gear shifting is finished.

In some embodiments, after receiving the third input, the water output level of the faucet may be shifted continuously or a single time depending on the duration of the third input.

The third target time length is a judgment standard for controlling the water yield gear of the faucet to perform continuous gear shifting and single gear shifting, wherein the water yield gear of the faucet is controlled to perform single gear shifting when the duration of the third input is shorter than the time length of the third target time length, and the currently set water yield gear is displayed on the display screen 450.

The duration of the third input from the first sensor 440 is shorter than the third target duration, a single shift of the water output level is performed, the water output level is shifted up to 200 ml, and the display screen 450 displays that the water output level is 700 ml.

In specific implementation, the quantitative gear of each adjustment of the water yield gear can be set by a user according to requirements, for example, the quantitative gear of each adjustment can be set to be a quantitative gear of 200 ml, 500 ml, 700 ml, 100 ml and the like.

It can be understood that the adjustment of the water yield gear can be to increase the water yield of the faucet by adjusting up or decrease the water yield of the faucet by adjusting down.

In actual implementation, a third input that the user stays on the first sensor 440 for no more than a third target duration may be referred to as a short tap; a third input to the first sensor 440 that has stayed longer than the third target duration is referred to as a sustained tap.

That is, the user briefly touches the first sensor 440 to control the water output gear of the water supply system to perform a single gear shift, thereby realizing the quantitative water output control.

In some embodiments, the third input to the first sensor 440 by the user has a duration no shorter than the duration of the third target, and the water output level of the faucet is continuously shifted.

And continuously adjusting the water yield gear of the faucet step by taking the second target time interval as a standard until the user does not input the first press input to finish gear shifting.

The second target time interval is a time standard for adjusting each gear in the continuous shifting process of the water yield gear, and in the time period that the duration of the third input of the user to the first sensor 440 exceeds the third target time period, the water yield is adjusted by one gear until the third input is no longer received every time the second target time interval passes.

In actual implementation, the second target time interval, the third target time duration and the quantitative gear of each adjustment can be set according to requirements.

Take the third target time period as 3 seconds and the second target time interval as 1 second as an example.

The current water yield gear is 500 ml, after the duration of the third input exceeds 3 seconds, the water yield gear of the faucet starts to be continuously adjusted step by step, the water yield gear is adjusted to 700 ml in the 4 th second, the gear is continuously adjusted up in the 5 th second, the water yield gear is 900 ml, and the gear adjustment is stopped until the third input is not received any more.

And through setting the third target time length and the second target time interval, the continuous step-by-step adjustment of the water yield of the faucet is realized according to the continuous input of the user to the first sensor 440.

It is understood that the adjustment variation process of the water output is displayed on the display screen 450, and the user can adjust the adjustment process according to the current water output gear displayed on the display screen 450 to determine whether to stop inputting the third input.

It should be noted that the third input of the user to the first sensor 440 is used to control the water output of the water outlet 111 of the faucet, and after the user needs to set the water output gear, the user needs to operate the handle again to rotate and stop in the first direction to control the corresponding water purifier to produce water, and the solenoid valve is opened to allow the faucet to discharge water quantitatively.

In some embodiments, the adjustment of the water output gear of the faucet may also be performed by adjusting the water output gear information displayed on the display screen 450.

The display screen 450 may display the current water yield gear information, and the user may adjust the water yield gear information on the display screen 450 through touch operation of the display screen 450.

The single shift of the water yield gear information on the display screen 450 may be represented as a touch input, including but not limited to a click input, a slide input, a press input, and the like.

In this embodiment, receiving the input of the user performing the single-time shift or the continuous shift on the water yield gear information on the display screen 450 may be represented as receiving a touch operation of the user on the display area of the display screen 450.

In order to reduce the user misoperation rate, the touch operation area may be limited to a specific area, such as the lower middle area of the display area of the faucet display screen 450; or a target control is displayed on the interface of the display screen 450, and the water yield gear can be adjusted by touching the target control.

For example, the user briefly touches a target control for adjusting the water yield gear on the display screen 450, so as to realize single gear shifting of the water yield gear; or, the user briefly touches the upper middle of the display screen 450 to control the water yield gear to shift up, and briefly touches the lower middle of the display screen 450 to control the water yield gear to shift down.

For example, the user continuously touches a target control for adjusting the water yield gear on the display screen 450 to realize the step-by-step continuous gear shifting of the water yield gear; or, the user continues to touch the upper middle of the display screen 450, controls the water yield gear to be shifted up by multiple steps, and continues to shift up by one step every time a second target time interval passes until the input to the display screen 450 is no longer received.

It should be noted that, after the user sets the water output, the user needs to operate the handle to rotate in the first direction to control the water output of the faucet water outlet 111.

In some embodiments, when the faucet is currently in the water outlet state, a fourth input is received from the user to rotate the handle in the first direction, the control solenoid valve is closed, and the water outlet 111 of the faucet is cut off.

In this embodiment, the faucet is currently in the water-out state, and at this time, the user rotates the second input of the handle in the first direction to control the water outlet 111 of the faucet to cut off water, and the faucet enters the standby state.

It can be understood that the fourth input is a control instruction for changing the current on-off state of the electromagnetic valve, the faucet is in a quantitative water outlet state or a continuous water outlet state, and the fourth input can control the electromagnetic valve to be closed, so that the faucet does not discharge water any more.

In actual implementation, when a user needs to stop the water outlet of the faucet, the operating handle rotates to a first target position in the first direction, the water outlet 111 of the faucet does not discharge water any more, the water cut-off control process is simple, and the handle can automatically reset after reaching the target position without resetting the user.

In some embodiments, when the front faucet is in the water-off state, a fifth input of the user to the first trigger 420 on the faucet is received, in response to the fifth input, the water purifier can also be controlled to produce water, and the solenoid valve is controlled to open to enable the water outlet 111 of the faucet to produce water for the user to use.

And when the current faucet is in a water outlet state, receiving a sixth input of a user to the first trigger 420 on the faucet, and responding to the sixth input, and controlling the water outlet 111 of the faucet to cut off water at the moment.

It will be appreciated that the fifth input is a command to control the faucet to flow, the sixth input is a command to control the faucet to cut water, and the user is the fifth or sixth input to the first trigger 420, which is only relevant to whether the faucet is currently in a water cut state or a water flow state.

The first trigger 420 is installed on the faucet, belongs to a non-contact trigger, and can trigger an input signal by receiving a shielding signal within a target distance, so that the water supply system receives a fifth input and a sixth input.

The target distance is an effective distance at which the first trigger 420 can receive the input signal, and when the region outside the target distance is shielded, the first trigger 420 cannot be effectively triggered, and control of water outlet and water cut-off of the faucet cannot be realized.

The target distance of the first trigger 420 may be set according to the category of the first trigger 420 and the use environment of the water supply system.

In practical implementation, the first trigger 420 may be a trigger device emitting infrared rays, and receive infrared rays reflected by a user through an infrared ray reflection principle, and form an electric control signal, that is, a fifth input and a sixth input, in an internal integrated circuit to control the faucet to discharge water and cut off water.

Taking the first trigger 420 as an infrared trigger device and the water supply system as a kitchen scene as an example, the target distance can be set to 20 cm, and the first trigger 420 can shield the water supply system within a range of 20 cm, so that the control of water outlet and water cut-off of the faucet can be realized, and the effective range of 20 cm can limit the situation that other equipment in the kitchen causes false triggering on the first trigger 420.

The first trigger 420 is sensitive in triggering, so that the control process of water outlet and water cut-off of the faucet is simplified, the situation of false triggering can be effectively avoided by setting the target distance, and the overall operability of the water supply system is improved.

In some embodiments, after receiving the fifth input, further determining whether to control the faucet to output water according to the inlet water temperature of the faucet.

In actual implementation, the user occludes the first trigger 420, and the operation that the duration of the fifth input does not exceed the target duration is called short occlusion; the user occludes the first trigger 420, and the operation of the fifth input having a duration exceeding the target duration is called continuous occlusion.

It can be understood that the time that the user blocks the first trigger 420 for different time is different, the received fifth input is different, and whether to control the water outlet 111 of the faucet according to the different fifth input and the difference between the current faucet water inlet temperature and the target temperature.

The current water inlet temperature of the faucet is not higher than the target temperature, the duration of the fifth input is shorter than the target duration, at the moment, the water outlet 111 of the faucet is controlled to discharge water, the temperature of the water flowing out of the faucet is below the target temperature, the water can directly flow out, and a user cannot be scalded.

The user continuously shields the first trigger 420, the duration of the fifth input is not shorter than the target duration, and the tap water outlet is directly controlled without judging whether the water inlet temperature of the tap exceeds the target temperature.

The current water inlet temperature of the faucet is higher than the target temperature, the user shields the first trigger 420, the duration of the fifth input is shorter than the target duration, at the moment, the water outlet 111 of the faucet is controlled to be cut off, water with the temperature higher than the target temperature cannot directly flow out, and the user is prevented from being scalded.

In actual implementation, the duration of the fifth input is shorter than the target duration, the water outlet 111 of the faucet is controlled to be cut off, the water with the temperature higher than the target temperature does not flow out directly, and the user is reminded by displaying a reminding message on the display screen 450 of the faucet or flashing the breathing lamp 460 in a target manner.

The display screen 450 of the faucet displays the reminding information including the current water inlet temperature value of the faucet and the prompt of continuously shielding the first trigger 420 from controlling water outlet.

The faucet's breathing light 460 blinks in a targeted manner, wherein the targeted manner may appear as at least one of: target blinking color, target blinking interval, target blinking brightness, and the like.

According to the control method provided by the embodiment of the invention, the handle rotates in the first direction and the second direction to input the first input and the second input, and the first sensor 440 inputs the third input to control the operation actions such as the water outlet start-stop, the water outlet temperature and the water outlet quantity in the water supply system, wherein the actions controlled by the three inputs can be combined and replaced.
