A first embodiment of the present invention proposes a water supply system, as shown in fig. 2, comprising:

a water supply line 202;

a water outlet device 204 connected to the water supply line 202, wherein the water supply line 202 is fed with water based on the opening of the water outlet device 204;

A flow detection device 206, disposed on the water supply pipeline 202, for detecting a water flow signal of the water supply pipeline 202;

the water pump 208 is disposed on the water supply line 202, and the water pump 208 is turned on based on the detection of the water flow signal by the flow rate detection device 206, and the water pump 208 is turned off based on the detection of the water flow signal by the flow rate detection device 206.

In the embodiment of the present invention, the water inlet valve is not disposed in the water supply pipeline 202 of the water supply system, so that the influence of the water inlet valve on the water hammer and the water pressure in the water supply pipeline 202 is reduced, and therefore, by controlling the opening of the water outlet device 204, water can directly flow into the water supply pipeline 202 from the water supply source 230, and the water flow forms a water supply passage by utilizing the water pressure of the water flow, so that the flow detection device 206 detects the water flow signal, and further, the operation of the water pump 208 is controlled.

It should be noted that, in the related art, a water inlet valve is disposed on the water supply pipeline, and the water inlet valve can be used to conveniently control water inlet, and reduce the influence of water hammer and water pressure in the water supply pipeline on the water supply system. However, in the related art, the water inlet valve of the water supply pipeline needs to be given by the water supply system to make on-off operation, and when the flow detection device cannot send out the starting signal, the water inlet valve of the water supply pipeline becomes a hindrance to system water inlet of the water supply system, so that the water supply system of the invention cancels the water inlet valve on the water supply pipeline.

Additionally, in some embodiments, the first purification device 210 may be a filtration device of an RO (Reverse Osmosis) cartridge. Wherein, the RO filter core uses the osmotic pressure difference as the dynamic membrane separation technology.

In any of the above embodiments, the water supply system further comprises:

the drain line 212 is connected to the first water outlet 2102 of the first purifying device.

On the other hand, when the drain valve 214 of the drain pipeline 212 is controlled to be closed, the drain pipeline 212 is cut off, so that clean water (i.e., unconcentrated water) is prevented from continuously flowing out of the drain pipeline 212 due to the fact that the drain valve 214 is normally opened under the condition that a water supply system is closed, and the waste of domestic water is avoided, so that the use cost of a user is increased. In the embodiment of the invention, the drain valve 214 of the drain pipeline 212 is closed to control the drain pipeline 212 to be cut off, so that the use cost of a user is greatly reduced, and the accuracy of the whole water supply system is improved.

It should be noted that, the above-mentioned drain valve adopts a special waste water solenoid valve, and the special waste water solenoid valve is different from the waste water solenoid valve in the related art. Because the waste water electromagnetic valve in the related art is in a normally open state, after the water inlet valve of the water supply pipeline is canceled, the waste water electromagnetic valve can generate a waste water long flow phenomenon, so that the special waste water electromagnetic valve can realize the dual functions of the water inlet electromagnetic valve and the waste water electromagnetic valve based on the principle of a water inlet electromagnetic valve and a waste water plug. The waste water plug can realize the function of the waste water electromagnetic valve, namely, the special waste water electromagnetic valve is closed to realize complete closing of the drainage pipeline, so that waste water long flow is avoided.

In the embodiment of the invention, the pure water loop is formed through the water return pipeline 218 to flush the drain valve 214, so that the phenomenon that the drain valve 214 in the drain pipeline 212 is scaled due to long-term concentrated water discharge to block the concentrated water port 232 is avoided, and the water supply system is not smoothly discharged, thereby influencing the service life of the water supply system. Therefore, by providing the return water line 218, not only is the user facilitated to clean the water supply system, but the service life of the water supply system is also extended.

It should be noted that, the drain valve 214 in the water supply system of the present invention does not adopt a flushing solenoid valve, and the system will belong to a water supply system that cannot be flushed, so that scaling phenomenon is very easy to occur at the waste water end, and in order to avoid scaling and blocking of the waste water valve, the waste water at the waste water end needs to be replaced by pure water in time. Therefore, the pure water on the second water supply pipeline 2024 flows back to the first water supply pipeline 2022 through the water return pipeline 218, so that the water entering the first purifying device 210 is cleaner, and the dirt concentration of the water discharged by the water discharge pipeline 212 is reduced, thereby reducing the scaling of the wastewater electromagnetic valve and enhancing the stability and reliability of the water supply system. In addition, the water supply system of the invention also solves the problem of first cup water in the water supply system through the water return pipeline 218.

In addition, the return line 218 may be configured to accommodate the specific needs of the first cup of water. For example, by providing the return water line 218, a return flow can be performed when the user takes in the first cup of water, so that the first cup of water that is taken out is also pure water.

In this embodiment, a water return line 218 of the water supply is provided with a first check valve 220 and a water inlet valve 222. On the one hand, the water return pipeline 218 is controlled to be turned on or off by controlling the opening or closing of the water inlet valve 222, so that the water supply system can clean the water outlet valve 214 according to reasonable requirements, and the concentrated water can be discharged from the concentrated water port 232 in time, so that the whole water supply system is safer and more sanitary. On the other hand, the water flow of the water return pipeline 218 is kept flowing unidirectionally and pressure is maintained by arranging the first one-way valve 220, so that the rear end of the first one-way valve 220 always has unidirectional pressure, and the water of the water return pipeline 218 is ensured not to enter the flow detection device 206 due to reverse pressure backflow under the condition that the water inlet valve 222 is closed, so that abnormal starting of the flow device is caused, and the stability of a water supply system is ensured.

In any of the above embodiments, the water supply system further comprises:

In any of the above embodiments, the water supply system further comprises:

the third purifying device 226 is disposed on the second water supply line 2024, and is used for purifying water in the second water supply line 2024.

In this embodiment, the second water supply line 2024 is provided with a third purifying means, and the water having been purified by the second purifying means and the first purifying means 210 flows into the second water supply line 2024, and the third purifying means purifies the water of the second line, which has been purified twice, again, so as to ensure that the water supply system can provide purer and more sanitary water to the user.

In this embodiment, the second check valve 228 is disposed between the first purifying device 210 and the third purifying device, and the second check valve 228 can keep the water flowing unidirectionally and keep pressure, so that the rear end of the second check valve 228 always has unidirectional pressure, and therefore, under the condition of water cut-off or the like, the water of the third purifying device cannot flow into the first purifying device 210 in a backward way due to the reverse pressure, so that the first purifying device is prevented from being damaged due to the backward flow, and the service life of the water supply system is ensured.

It should be noted that, the problem faced by the control system of the novel flow detection device in the related art is mainly the problem of restarting and water inflow, the problem of restarting is caused by unsmooth water inflow, and the water supply system has self-consistent tightness, and the tightness has no passage, so even if the water supply source in the water supply system is not deficient, the water inflow of the water supply system is extremely difficult, and the difficulty can be solved by setting schemes such as water passage, etc., but the water supply system needs to be added with branches, which is slightly complicated. Therefore, the present invention provides a new water supply system for the novel flow detection device control system, which can solve a series of problems that the water supply system cannot be started due to the fact that water cannot enter the flow detection device when water is stopped or the water supply system is used for the first time, or the water supply system cannot be started again due to the fact that pressure is released at the rear end after normal water supply, or the water is difficult to enter the flow detection device 206 due to the sealing of the water outlet device 204 when water is lost.

In a first embodiment, fig. 3 shows one of flow charts of a water supply control method according to an embodiment of the present invention, where the water supply control method includes:

step 302, controlling the operation of the water pump according to the water flow signal detected by the flow detection device.

In this embodiment, the water supply system is provided with a water supply line, a water outlet device, a flow detection device, and a water pump, wherein the water outlet device is connected with the water supply line, and the water supply line is provided with the flow detection device and the water pump. In the embodiment of the invention, the water inlet valve is not arranged in the water supply pipeline of the water supply system, so that the influence of the water inlet valve on water hammer and water pressure in the water supply pipeline is reduced, therefore, by controlling the opening of the water outlet device, water can directly flow into the water supply pipeline through the water supply source, the water flow forms a water supply passage by utilizing the water pressure of the water flow, the flow detection device detects the water flow signal, and the work of the water pump is controlled. According to the invention, the water outlet device is started, so that the water supply pipeline is enabled to feed water, the control of the water flow signal detected by the flow detection device on the work of the water pump is further realized, the reasonable control of the work of the water supply system is further realized, the difficult problem of difficult water feeding under the condition of water shortage or restarting of the novel flowmeter control system in the prior art is solved, the use of the water supply system by a user is facilitated, and the reliability of the whole water supply system is improved.

In the above embodiment, the operation of the water pump is controlled according to the water flow signal detected by the flow detection device, which specifically includes: controlling the water pump to be started based on the water flow signal detected by the flow detection device; and controlling the water pump to be turned off based on the fact that the flow detection device does not detect the water flow signal.

In the embodiment, the flow detection device detects the water flow of the water supply pipeline, if the flow detection device detects a water flow signal, which indicates that a user needs water, the water pump of the water supply system is controlled to be started so as to perform pressure treatment on the water entering the water supply pipeline, so that the water can smoothly flow into the water outlet pipeline for the user to use; if the flow detection device does not detect the water flow signal, which means that the user does not need water or the water is finished, the water pump of the water supply system is controlled to be closed, the water in the water supply pipeline is not pressurized any more, and the situation that the flow detection device mistakenly detects the water flow signal due to the flow of the water caused by the pressurization of the residual water remained in the water supply pipeline is prevented, so that the water supply system is restarted, and the control process of the water supply system is out of control. In the embodiment of the invention, the water flow signal detected by the flow detection device is used for controlling the opening or closing of the water pump of the water supply system, so that the reasonable use of the water supply system by a user is ensured, and the accuracy of the water supply system is improved.

In a second embodiment, fig. 4 shows a second flow chart of a water supply control method according to an embodiment of the present invention, where the water supply control method includes:

step 402, controlling the operation of the water pump according to the water flow signal detected by the flow detection device;

step 404, controlling the opening of a drain valve of a water supply system based on the opening of a water pump;

step 406, controlling the drain valve of the water supply system to close based on the water pump closing.

In this embodiment, on the one hand, control water pump of water supply system and open, control drain valve of drain pipe and open, make the concentrated water that produces in the work of first purifier follow exhaust pipe and discharge through the drain valve for the water that passes through first purifier purification is purer, and then has guaranteed that water supply system provides safer more sanitary water for the user, has improved the reliability of whole water supply system.

On the other hand, the water pump of the water supply system is controlled to be closed, the water supply system is controlled to stop working, and the first purifying device is stopped to continuously purify the inflow water, so that the water pump is controlled to be closed, and meanwhile, the drain valve of the drain pipeline is controlled to be closed, so that clean water (i.e. unconcentrated water) is prevented from continuously flowing out of the drain pipeline due to the fact that the drain valve is normally opened under the condition that the water supply system is closed, and the use cost of a user is increased due to the fact that domestic water is wasted. In the embodiment of the invention, the water pump is controlled to be closed and the drain valve of the water supply system is controlled to be closed at the same time, so that the use cost of a user is greatly reduced, and the accuracy of the whole water supply system is improved.

In a third embodiment, fig. 5 shows a fifth flow chart of a water supply control method according to an embodiment of the present invention, wherein the water supply control method includes:

step 502, controlling the operation of a water pump according to a water flow signal detected by a flow detection device;

step 504, receiving a water inlet valve opening signal to control the opening of the water inlet valve.

In any of the above embodiments, the water supply control method further includes: and receiving a water inlet valve opening signal to control the opening of the water inlet valve.

In this embodiment, when the drain valve in the water supply system needs to be cleaned, the water supply system receives a water inlet valve opening signal, controls the water inlet valve of the water return pipeline to be opened, and the water return pipeline is communicated, so that water in the water supply system passes through the water return pipeline to form a pure water loop to flush the drain valve. According to the embodiment of the invention, the water inlet valve is controlled to be opened by receiving the water inlet valve opening signal, so that the scaling blockage of the drain valve in the drain pipeline due to long-term concentrated water discharge is avoided, the use of a user is facilitated, and the stability of a water supply system is improved.

In the above water supply control method, the execution sequence of step 502 and step 504 is not limited.

In the fourth embodiment, in the control system of the flowmeter water supply system in the related art, the flowmeter is used to replace the high-voltage switch, and the flowmeter is pushed by the pressure maintaining effect brought by the one-way valve during each water taking, so that the water supply system completes the water taking action. However, under the condition of water shortage, the water around the flowmeter is drained, so that the flowmeter cannot output effective signals, a water supply system cannot effectively feed water when water is supplied, and the flowmeter cannot be started to form dead circulation. Although in the above-mentioned case, the water inlet valve on the water supply pipeline can be opened by the signal of the electric control system and the water level sensor at the front end, because the rear end of the flowmeter is the pure water end, under the condition of closing the faucet (i.e. the water outlet device), the water is extremely difficult to enter the extreme end of the water supply system under the influence of pressure, so that the double adverse conditions of 'system water shortage and difficult water inlet' are formed, and the use of the water supply system is directly influenced.

The novel flowmeter control system cancels the water inlet valve on the water supply pipeline, the motive power for driving the flowmeter to rotate is the tap water pressure, when a user opens the water tap, a water inlet passage is naturally formed with the water supply pipeline and the filtering device, the tap water pressure drives the flowmeter to rotate, the whole machine starts to produce water, and the starting mode greatly increases the reliability of the system. The water supply system pushes out water flow in a pressure maintaining mode, so that the pressure relief problem exists, and the water faucet is driven by water pressure, so that the problem cannot occur.

In order to better illustrate the specific application form of the invention, the invention provides an embodiment that the water supply system adopts the following three different filter elements with different levels as the purifying device. Wherein, the different filter core of three kinds of different levels is as purifier, specifically includes: (1) a front PAC filter element, an RO membrane and rear active carbon; (2) a front-end PCB filter element and an RO membrane; (3) The purification device comprises a front PP filter element, a front carbon rod, an RO membrane and a rear carbon rod, wherein the front PAC filter element is a filter element formed by integrating front PP cotton, front carbon rod and rear PP cotton, and the front PCB filter element is a filter element formed by integrating front PP cotton, front carbon rod, rear PP cotton and rear carbon rod.

Fig. 6 shows a fourth flow chart of a water supply control method according to an embodiment of the present invention, wherein the water supply control method includes:

step 602, opening a faucet;

step 604, driving by tap water pressure;

step 606, judging whether the flowmeter rotates, if so, proceeding to step 608, otherwise proceeding to step 610;

step 608, starting a water pump;

step 610, waiting for water to enter;

and step 612, starting to prepare water.

In the first case, the core of the upgraded water system employing the new flow meter control system is constituted by: pressure reducing valve, front PAC filter element, booster pump, RO membrane, special waste water valve, rear active carbon, flowmeter, pure water return passage, tap, etc. The pressure reducing valve is positioned at the forefront end of the water purifying system, the waste water valve adopts a special waste water valve, after the tap is opened, tap water pressure produces part of pure water from the pure water end, the pure water can drive the flowmeter to rotate, and after the flowmeter rotates, the system starts to produce water. When the water tap is closed, the flowmeter stops rotating, the system can close the water pump, and the operation is simple and reliable.

In the second case, the core structure of the upgrade water system adopting the novel flowmeter control system is as follows: pressure reducing valve, front-mounted PCB filter element, booster pump, RO membrane, special waste water valve, flowmeter, pure water reflux passage and tap. The mode of adopting pressure maintaining to push water in the related art requires a large amount of water in the back carbon, but the back carbon water storage capacity of the PCB filter element is often insufficient, so that the situation of water pushing failure is easy to cause. Therefore, the system is not only suitable for the three-stage filtering and purifying device, but also suitable for the two-stage filtering device of the PCB.

In the third case, the core structure of the upgrade water system adopting the novel flowmeter control system is as follows: pressure reducing valve, front PP filter element, front carbon rod, booster pump, RO film, special waste water valve, flowmeter, pure water return passage, rear carbon rod and tap. The purification device of the water supply system is a four-stage purification device, wherein the flowmeter is arranged between the rear activated carbon and the faucet, and the functions can be realized.
