After the user closes the water using equipment 150, when the water flow monitoring device 160 monitors that no water flow is generated, a monitoring signal is sent to the regulating valve 140, so that the regulating valve 140 regulates the opening to be increased or is completely opened, a large amount of water enters the water storage cavity 121 through the first pipeline 130, the water pressure and the water quantity when the water using equipment 150 is used are ensured not to be influenced by the water inlet state of the water storage cavity 121, and the water pressure and the water quantity of the water using equipment 150 meet the normal use requirements.

In the present embodiment, the damper 140 is an electronic damper. The electronic regulating valve comprises an electric actuating mechanism and a valve, and the electric actuating mechanism is used for regulating the opening of the valve. The electric actuator is electrically connected with the water flow monitoring device 160. After the water flow monitoring device 160 monitors the water flow, the opening of the valve 140 is adjusted to be reduced or closed by the electric actuator to adjust the flow rate of the first pipeline 130, so that the water storage cavity 121 is filled with water or cannot be filled with water, and the water consumption of the water using equipment 150 is ensured to meet the use requirement. In another embodiment, the regulator valve 140 may also be manually opened or closed.

In another embodiment, the regulating valve 140 may also be a rotary regulating valve or a pressure regulating valve.

Specifically, the water flow sensor includes a valve body, a rotor assembly, a hall element, and a controller. The valve body is disposed within the second conduit 170 and the rotor assembly is disposed within the valve body. The Hall element is arranged on the valve body and used for sensing the state of the rotor assembly, the Hall element is electrically connected with the controller, and the Hall element feeds back a sensing signal to the controller. The regulating valve 140 is electrically connected to the controller. When water flows through the rotor assembly of the water flow sensor, the rotor in the rotor assembly rotates, and the rotating speed changes linearly with the flow. Meanwhile, the Hall element outputs a corresponding sensing signal to be fed back to the controller, and the controller judges the water flow. The sensing signal output by the hall element is fast and stable, so that the water flow sensor is sensitive to water flow, and meanwhile, when water flow is generated in the second pipeline 170, the rotor assembly starts to rotate, so that the water flow sensor can sense the pipeline water flow with lower flow, and the application range is wide.

Further, the water flow sensor is a hole plate type water flow sensor, an impeller type water flow sensor, an ultrasonic water flow sensor or an electromagnetic water flow sensor.

In one embodiment, the water flow monitoring device 160 is disposed on the second pipeline 170. When the user uses the water using equipment 150, the water flow monitoring device 160 monitors that water flow is generated in the second pipeline 170, and sends a monitoring signal to the regulating valve 140, so that the regulating valve 140 regulates the opening degree to be reduced or closed, so as to regulate the water flow in the first pipeline 130 communicating the water storage cavity 121 with the water feeding pipeline 110 to be reduced or closed, further control the water inlet amount in the water storage cavity 121 to be reduced or stopped, ensure that the water pressure and the water amount of the water discharged from the water using equipment 150 meet the use requirements, and ensure that the user uses water conveniently.

In one embodiment, there are two water flow monitoring devices 160, one of the water flow monitoring devices 160 is disposed on the second pipeline 170, and the other water flow monitoring device 160 is disposed in the water outlet channel. When a user uses the water consumption device 150, the water flow monitoring device 160 monitors that water flows are generated in the second pipeline 170 and the water outlet channel successively, and sends a monitoring signal to the regulating valve 140, so that the regulating valve 140 regulates the opening degree to be reduced or closed, the water flow in the first pipeline 130 communicating the water storage cavity 121 and the water supply pipeline 110 is regulated to be reduced or closed, the water inflow in the water storage cavity 121 is controlled to be reduced or stopped, and the convenience of water consumption of the user is ensured.

When only one of the water flow monitoring devices 160 detects the water flow state and the other water flow monitoring device 160 does not detect the water flow, the adjustment valve 140 is not controlled to adjust the opening degree to change. By arranging two water flow monitoring devices 160, the monitoring precision and accuracy can be improved, and the mis-adjustment of the adjusting valve 140 can be avoided.

In another embodiment, the opening of the adjusting valve 140 may be adjusted to be reduced or closed only when one of the water flow monitoring devices 160 detects water flow, so as to adjust the water flow in the first pipeline 130 to be reduced or closed, and ensure that the water supply pipeline 110 can supply water to the water using equipment 150 through the second pipeline 170.

In an embodiment, the water using equipment 150 further has a water outlet, the water outlet is communicated with the water outlet channel, the water flow monitoring device 160 is disposed outside the water using equipment 150, and the monitoring direction of the water flow monitoring device 160 intersects with the water flow direction of the water outlet. When water flows are generated at the water outlet, the monitoring direction of the water flow monitoring device 160 is intersected with the water flow direction of the water outlet, so that the water flow monitoring device 160 can monitor the water flows, a water flow monitoring signal is generated immediately, the opening of the adjusting valve 140 is adjusted to be reduced or closed, the water flow in the first pipeline 130 is adjusted to be reduced or closed, the water inflow in the water storage cavity 121 is controlled to be reduced, the water pressure and the water amount of the water using equipment 150 are not influenced by the water inflow state of the water storage cavity 121 when the water using equipment is used, and the water using convenience of a user is ensured.

Specifically, the water flow monitoring device 160 may be installed on an outer wall of the water consumption equipment 150, or the water flow monitoring device 160 may be installed at another position, as long as the monitoring direction of the water flow monitoring device 160 is intersected with the water flow direction of the water outlet, so as to facilitate the water flow monitoring device 160 to monitor the water flow signal of the water consumption equipment 150.

In one embodiment, the number of consumers 150 is at least two, and different consumers 150 are arranged in parallel with respect to the water supply line 110. When at least two water-using devices 150 are arranged on the water supply pipe 110 in parallel, when the regulating valve 140 closes the first pipeline 130, the water flow in the second pipeline 170 is increased, so that the flow of the first pipeline 130 and the flow of the second pipeline 170 can be regulated conveniently through the regulating valve 140, the water pressure and the water quantity when the water-using devices 150 are used can be ensured not to be influenced by the water inlet state of the water storage cavity 121, and the water pressure and the water quantity of the water-using devices 150 can meet the normal use requirements.

Specifically, each water-consuming device 150 is connected to the water-supplying pipe 110 through at least one second pipeline 170, so as to realize that different water-consuming devices 150 are arranged in parallel with respect to the water-supplying pipe 110. The water using device 150 is connected to the water supply pipe 110 through a second pipe 170, and the second pipe 170 is connected in parallel to the water supply pipe 110. When the regulating valve 140 closes the first pipeline 130, the water flow in the second pipeline 170 is increased, so that the water flow of the water using equipment 150 on the second pipeline 170 is increased, and the water pressure and the water amount of the water using equipment 150 can meet the normal use requirement.

In another embodiment, the number of the water consuming devices 150 is at least two, wherein at least two water consuming devices 150 are connected to the water supply pipe 110 through a second pipeline 170. The regulating valve 140 closes the first pipeline 130 to stop the water inlet of the water storage chamber 121, so that the second pipeline 170 has sufficient water flow to supply the water consumption equipment 150, and the water pressure and water quantity of the water consumption equipment 150 can meet the normal use requirement under the condition that at least two water consumption equipment 150 are connected to the water supply pipeline 110 through the second pipeline 170.

In one embodiment, the water consuming device 150 is a shower, a hand wash faucet, or a vegetable wash faucet. When water enters the water storage cavity 121, and a shower, a hand washing faucet or a vegetable washing faucet is used, the water flow monitoring device 160 can reduce or close the opening of the regulating valve 140 on the first pipeline 130 of the water storage cavity 121, so as to ensure that the water pressure and the water amount of the water using equipment 150 are not affected by the water inlet state of the water storage cavity 121, and ensure that the water using convenience of a user is ensured.

In one embodiment, the control valve 140 is used to control the first pipeline 130 to be connected or closed according to the monitoring signal of the water flow monitoring device 160. When a user uses the water consumption device 150, the water flow monitoring device 160 senses that water flow is generated, and sends a monitoring signal to the regulating valve 140, so that the regulating valve 140 closes the first pipeline 130 connected with the water storage cavity 121, and further the water storage cavity 121 cannot continuously feed water; when the user closes the water using device 150 and the water flow monitoring device 160 senses that no water flow is generated, a monitoring signal is sent to the adjusting valve 140, so that the adjusting valve 140 opens the first pipeline 130 connected to the water storage cavity 121, and further, the water storage cavity 121 is filled with water. The water pressure and the water quantity when the water using equipment 150 is used are not influenced by the water inlet state of the water storage cavity 121, and the convenience of water use for users is ensured.

In one embodiment, the water pressure in water supply line 110 is less than or equal to 0.2 MPa. The requirement of the water pressure of the green building for entering the house is not more than 0.2MPa, and the water inflow to the water storage cavity 121 under the water pressure of 0.2MPa can make the water quantity and the water pressure of other water using equipment 150 not meet the use requirement, so that the water inflow in the water storage cavity 121 can be adjusted according to the water quantity of a user when the user uses the water using equipment 150 under the water pressure of 0.2MPa by the household water supply system 100; when the water using equipment 150 is closed, a large amount of water enters the water storage cavity 121, so that a user can ensure that enough water exists when using the water storage cavity 121 next time, the water pressure and the water amount when the water using equipment 150 is ensured not to be influenced by the water inlet state of the water storage cavity 121, and the water pressure and the water amount of the water using equipment 150 reach normal use requirements.

In one embodiment, the water supply pipe 110 has an inner diameter of 20 mm. The water meter used in the general housing and apartment is adapted to be connected to a water supply pipe 110 having an inner diameter of 20mm and an outer diameter of 27 mm. Under the restriction condition of the water supply pipe 110, when water enters the water storage cavity 121, the water amount and the water pressure of other water using equipment 150 cannot meet the use requirements. Therefore, the water supply relationship between the water storage chamber 121 and the respective water consumers 150 can be effectively adjusted by the household water supply system 100 in the case that the water supply amount of the water supply pipe 110 is limited.

In one embodiment, a liquid level monitoring device is disposed in the water storage chamber 121 and electrically connected to the regulating valve 140. When the liquid level monitoring device in the water storage cavity 121 monitors that the water inflow reaches the normal water level set by the water storage cavity 121, the liquid level monitoring device sends a signal to the regulating valve 140, the regulating valve 140 closes the first pipeline 130 connected with the water storage cavity 121, so that the water storage cavity 121 cannot continue to intake water, and the water amount in the water storage cavity 121 is kept at the normal water level without overflowing.

Further, the liquid level monitoring device is provided with a low liquid level detection portion and a high liquid level detection portion. When the water level in the water storage chamber 121 starts to be lower than the high liquid level detection portion and gradually moves toward the low liquid level detection portion, the liquid level monitoring device controls the regulating valve 140 to be gradually opened. When the water level in the water storage cavity 121 is not higher than the low liquid level detection part, the liquid level monitoring device controls the regulating valve 140 to be completely opened, and a large amount of water enters the water storage cavity 121 at the moment. If the water flow monitoring device 160 monitors the water flow signal of the water using equipment 150 and sends a monitoring signal to the regulating valve 140, the regulating valve 140 is closed to ensure that the water amount of the water using equipment 150 meets the use requirement. If the water flow monitoring device 160 monitors that the water consumption equipment 150 has no water flow signal, and the liquid level monitoring device monitors that the water level in the water storage cavity 121 does not reach the high liquid level detection part, the regulating valve 140 is fully opened under the common monitoring signal of the water flow monitoring device 160 and the liquid level monitoring device, so that a large amount of water enters the water storage cavity 121. When the water level in the water storage chamber 121 reaches the high liquid level detection portion of the liquid level detection device, the regulating valve 140 is closed, and water is no longer supplied to the water storage chamber 121 through the first pipeline 130.

In one embodiment, the fluid level monitoring device is a fluid level sensor. In particular, the level sensor may be a ball float level sensor, a magnetic level sensor, an ultrasonic level sensor or a radar level sensor.

In one embodiment, the household water supply system 100 further comprises a control system, and the water flow monitoring device 160 and the regulating valve 140 are electrically connected to the control system respectively. When the user is using the water using equipment 150, the water flow monitoring device 160 monitors that water flow is generated in the water outlet channel, a monitoring signal is sent to the regulating valve 140 through the control system, the control system controls the opening size of the regulating valve 140, so that the regulating valve 140 regulates the opening to be reduced or closed, the water flow in the first pipeline 130 for regulating and communicating the water storage cavity 121 and the water feeding pipeline 110 is reduced or closed, the water inflow in the water storage cavity 121 is further controlled to be reduced, the condition that the water pressure and the water amount of the water discharged from the water using equipment 150 meet the use requirements is ensured, and the convenience in water use of the user is ensured.

In one embodiment, the control system is controlled by a PLC control system. Specifically, the PLC control system comprises a power supply assembly, a microprocessor, a memory assembly, an input assembly and an output assembly. A water flow monitoring device 160 is connected to the input of the input module and a regulating valve 140 is connected to the output of the output module. When the monitoring signal of the water flow monitoring device 160 enters the input module through the input end, a program preset in the memory module is operated, and after the result is calculated by the microprocessor, the result is transmitted to the regulating valve 140 through the output end of the output module, so that the regulating valve 140 regulates the opening according to the monitoring signal, and the first pipeline 130 is communicated or closed. The information regulation between the water flow monitoring device 160 and the regulating valve 140 can not be disturbed by the outside through the connection of the PLC control system, and meanwhile, the PLC control system reacts rapidly, so that the household water supply system 100 is more sensitive and reliable.

Further, the water flow monitoring device 160 monitors the water flow and controls the opening of the regulating valve 140 in real time through the control system. When the user is using the water equipment 150, according to the different water volumes of use, the control system controls the water storage cavity 121 to have different water inflow through the opening of the control regulating valve 140, that is, when the water volume of the user needing the water equipment 150 is large, the switch of the water equipment 150 is rotated to the maximum, the water flow monitoring device 160 monitors the large water flow signal, the regulating valve 140 is completely closed through the control system, the water storage cavity 121 cannot be filled with water through the first pipeline 130, the water supply of the water supply pipeline 110 to the water equipment 150 is ensured, the water pressure and the water volume of the water output by the water equipment 150 are ensured to be maximum, and the water requirement of the user is ensured. When the user turns on the switch of the water using device 150 but does not rotate to the maximum, the water flow monitoring device 160 correspondingly adjusts the opening of the adjusting valve 140 through the control system according to the water flow. When a user uses the water using equipment 150 but does not need a large amount of water, the regulating valve 140 is not completely closed, so that the water storage cavity 121 keeps a certain water inflow through the first pipeline 130, the time that the water level in the water storage cavity 121 reaches the normal water level after the user uses the water using equipment 150 is shortened, and the user can conveniently use the toilet 120 next time.
