Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to a water purification equipment control circuit detection method and water purification equipment. Background Art

[0002] There are more and more high-flow water purifiers on the market. During use, the water purifier may continue to produce water without stopping, resulting in a large amount of water waste. Take a 400GP water purifier as an example (i.e. 1L / MIN water flow), if it stops after 1 hour, the direct waste of water is as high as 60L; the high-flow water purifier detects the state of the pressure switch signal, such as Figure 1 As shown, when the faucet is opened, the pressure switch detects a low-pressure signal and feeds this signal back to the host MCU. The host MCU controls the opening of the water inlet solenoid valve and the pressure-stabilizing pump. At this time, the water path is connected, water flows out from the faucet, and the user can get water. Conversely, after the faucet is closed, the pressure switch detects a high-pressure signal and feeds this signal back to the host MCU. The host MCU controls the closing of the water inlet solenoid valve and the pressure-stabilizing pump, and the entire machine stops running and cannot get water.

[0003] If the water purifier keeps producing water, it is usually caused by the following reasons: one is that the pressure switch signal is interfered or the body is damaged; the second is that the control circuit is damaged and the water inlet solenoid valve and the pressure regulating pump cannot be effectively controlled. For the first case, the water inlet solenoid valve and the pressure regulating pump can be turned off after detecting a certain period of continuous water production (the time when the pressure switch signal is a low-pressure signal or the running time of the pressure regulating pump) to achieve long-term water production shutdown protection for the water purifier. For the second case, since the water inlet solenoid valve and the pressure regulating pump in the control circuit of the water purifier use the same switching circuit (MOS or relay, etc.) for drive control, when the switching device is damaged, the pressure regulating pump and the water inlet solenoid valve are directly powered by hardware to turn on the load, and the MCU cannot control the above components, resulting in the drive circuit being in a powered state and the water path being connected. Even after the faucet is turned off, the whole machine is still running to produce water, causing a lot of water waste. It will only stop when the user discovers and unplugs the power.

[0004] Therefore, how to accurately detect the operating effectiveness of the water purifier control circuit has become an urgent problem to be solved. Summary of the invention

[0005] In view of this, the present invention provides a water purification equipment control circuit detection method and water purification equipment to solve the problem in the related art that the water purification equipment control circuit cannot be detected for effectiveness, resulting in the whole machine continuing to run and produce water after it fails, causing a large amount of water waste.

[0006] In a first aspect, the present invention provides a water purification equipment control circuit detection method, which is applied to a controller of the water purification equipment, wherein the water purification equipment control circuit comprises: a voltage-stabilizing pump control circuit, wherein a control end of the voltage-stabilizing pump control circuit is connected to the controller, and an output end is connected to a voltage-stabilizing pump power supply end, wherein the method comprises:

[0007] Performing water intake monitoring on the water purification equipment;

[0008] When it is detected that the water purification device has no water intake operation, outputting a first drive signal to disconnect the voltage-stabilizing pump control circuit to the control end of the voltage-stabilizing pump control circuit;

[0010] A fault detection result of the stabilizer pump control circuit is determined based on the voltage detection signal.

[0011] The present invention monitors the water intake of a water purifier, outputs a first drive signal to the control end of the voltage-stabilizing pump control circuit to disconnect the voltage-stabilizing pump control circuit when there is no water intake operation, and obtains a voltage detection signal of the voltage-stabilizing pump control circuit, so as to use the voltage detection signal to determine whether there is a fault in the voltage-stabilizing pump control circuit, thereby accurately detecting the operating effectiveness of the water purifier control circuit, reminding the user to cut off the power in time, and avoiding the waste of water resources.

If the voltage detection signal is a voltage signal at this time, it indicates that a component failure or the like occurs in the voltage-stabilizing pump control circuit, thereby realizing accurate detection of the voltage-stabilizing pump control circuit failure.

[0016] In an optional implementation, when the voltage detection signal is a no-voltage signal, it is determined that the fault detection result of the voltage regulating pump control circuit is that the circuit is valid.

[0017] The present invention outputs a first drive signal to disconnect the voltage-stabilizing pump control circuit to the control end of the voltage-stabilizing pump control circuit when there is no water intake operation. When the voltage-stabilizing pump control circuit is in effective operation, no voltage signal exists in the circuit. If the voltage detection signal is a no-voltage signal at this time, it indicates that the voltage-stabilizing pump control circuit is in a normal and effective operation state, thereby realizing accurate detection of the effectiveness of the voltage-stabilizing pump control circuit.

[0018] In an optional implementation, when it is determined that the fault detection result of the voltage regulator pump control circuit is a circuit failure, the method further includes:

[0020] The present invention can timely remind the user to perform power-off processing and avoid wasting water resources by performing a circuit fault alarm when the voltage-stabilizing pump control circuit fails.

[0021] In an optional implementation, when it is determined that the fault detection result of the voltage-stabilizing pump control circuit is that the circuit is valid, the step of monitoring the water intake of the water purification device is returned to.

[0022] The present invention realizes continuous detection of the effectiveness of the voltage-stabilizing pump control circuit by continuously monitoring water intake when detecting that the voltage-stabilizing pump control circuit is operating effectively, thereby avoiding the problem of water resource waste caused by device damage and improving user experience.

[0024] Obtaining the switch status of a pressure switch provided at the water outlet of the water purification equipment;

[0025] Based on the switch state, it is determined whether the water purification device is currently in a water intake operation.

[0026] The present invention monitors the switch state of the pressure switch at the water outlet of the water purification device to prevent the user from performing water extraction operation on the water purification device, thereby realizing accurate monitoring of the water extraction operation.

[0027] In an optional embodiment, the method further includes:

[0028] When it is detected that the water purification device has a water intake operation, a second drive signal for turning on the voltage-stabilizing pump control circuit is output to the control end of the voltage-stabilizing pump control circuit to control the voltage-stabilizing pump to be powered on and operate to produce water.

[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0052] There are more and more high-flow water purifiers on the market. During use, the water purifier may continue to produce water without stopping, resulting in a large amount of water waste. Take a 400GP water purifier as an example (i.e. 1L / MIN water flow), if it stops after 1 hour, the direct waste of water is as high as 60L; the high-flow water purifier detects the state of the pressure switch signal, such as Figure 1 As shown, when the faucet is opened, the pressure switch detects a low-pressure signal and feeds this signal back to the host MCU. The host MCU controls the opening of the water inlet solenoid valve and the pressure-stabilizing pump. At this time, the water path is connected, water flows out from the faucet, and the user can get water. Conversely, after the faucet is closed, the pressure switch detects a high-pressure signal and feeds this signal back to the host MCU. The host MCU controls the closing of the water inlet solenoid valve and the pressure-stabilizing pump, and the entire machine stops running and cannot get water.

[0053] Figure 2 This is the load control block diagram of the water purifier. If the water purifier keeps producing water, it is usually caused by the following reasons: one is that the pressure switch signal is interfered with or the body is damaged; the second is that the control circuit is damaged and cannot effectively control the water inlet solenoid valve and the pressure-stabilizing pump. For the first case, the water purifier can be shut down for long-term water production protection by closing the water inlet solenoid valve and the pressure-stabilizing pump after detecting continuous water production for a certain period of time (the time when the pressure switch signal is a low-pressure signal or the running time of the pressure-stabilizing pump). For the second case, if Figure 3 As shown, since the water inlet solenoid valve and the pressure regulating pump in the control circuit of the water purifier are driven and controlled by the same switching circuit (MOS or relay, etc.), when the switching device is damaged, the pressure regulating pump and the water inlet solenoid valve are directly powered by hardware to turn on the load, and the MCU cannot control the above components, causing the drive circuit to be powered all the time and the water path to be connected. Even after the faucet is turned off, the whole machine is still running to make water, causing a lot of water waste. It will not stop until the user discovers and unplugs the power.

[0054] Therefore, how to accurately detect the operating effectiveness of the water purifier control circuit has become an urgent problem to be solved.

[0055] Based on this, in order to solve the technical problem in the prior art that the water purifier cannot stop producing water due to the failure of components in the water inlet solenoid valve and the pressure-stabilizing pump control circuit, the embodiment of the present invention uses a logic control method to realize the detection and early warning reminder of the failed circuit; specifically, by separating the controller circuits of the water inlet solenoid valve and the pressure-stabilizing pump, independent control of the two components is realized, and a voltage detection scheme for the pressure-stabilizing pump control circuit is added. When a component failure occurs, the failure mode of the pressure-stabilizing pump control circuit is determined according to the logical relationship of the drive signal, and the user is reminded to cut off the power in time.

[0056] An embodiment of the present invention provides a water purification device, which includes: a controller and a voltage-stabilizing pump control circuit, wherein the control end of the voltage-stabilizing pump control circuit is connected to the controller, and the output end is connected to the voltage-stabilizing pump power supply end. The controller is used to execute a water purification device control circuit detection method provided by another embodiment of the present invention. The specific working principle and working process of the controller are described in detail in the following method embodiment, and will not be repeated here.

[0057] It should be noted that in the embodiments of the present invention, the water purification equipment is a water purifier and the controller is an MCU. In actual use, the water purification equipment can also be other equipment with water purification function, such as: water filtration equipment, etc., and the controller can also be other control chips with data processing functions such as single-chip microcomputers, but the present invention is not limited to this.

[0058] Specifically, Figure 4 As shown, the voltage regulator pump control circuit is composed of a first switch component Q1 and a first diode D1, wherein the control end of the first switch component Q1 is connected to the MCU control end, the first end is grounded, the second end is connected to the voltage regulator pump power supply end through the first diode D1, and the second end is also connected to the other end of the voltage regulator pump.

[0059] Exemplarily, the first switch component Q1 may be a switch device such as a MOS tube, a triode, an IGBT, etc., but the present invention is not limited thereto.

[0060] Furthermore, the above-mentioned water purification equipment also includes: a pressure switch arranged at the water outlet of the water purification equipment, the pressure switch is connected to the controller, the pressure switch is in an open state when the user operates the water purification equipment to draw water, and the pressure switch is in a closed state when the user does not operate the water purification equipment to draw water.

[0061] Specifically, the pressure switch is an inherent structure in existing water purification equipment. Its specific setting position and device selection can refer to the settings of existing water purification equipment such as water purifiers, and will not be repeated here.

[0062] The water purification device provided in the embodiment of the present invention also includes: a voltage detection circuit arranged in the voltage-stabilizing pump control circuit, the voltage detection circuit is connected to the controller, and is used to detect the voltage detection signal of the voltage-stabilizing pump control circuit and send the voltage detection signal to the controller.

[0063] For example, Figure 4 As shown, the voltage detection circuit includes a first resistor R1 and a second resistor R2, wherein one end of the first resistor R1 is connected to the MCU control end, and the other end is respectively connected to the control end of the first switch component Q1 and one end of the second resistor R2, and the other end of the second resistor R2 is grounded. By detecting the voltage on the second resistor R2, the voltage detection signal in the voltage regulating pump control circuit is determined.

[0064] The embodiment of the present invention identifies the user's water extraction operation by arranging a pressure switch at the water outlet of the water purification device, and realizes the voltage signal detection function of the voltage regulating pump control circuit by the voltage detection circuit in the voltage regulating pump control circuit.

[0065] Furthermore, the water purification device provided in the embodiment of the present invention also includes: a water inlet solenoid valve control circuit, wherein the control end of the water inlet solenoid valve control circuit is connected to the controller, and the output end is connected to the power supply end of the water inlet solenoid valve.

[0066] Specifically, Figure 5 As shown, the water inlet solenoid valve control circuit is composed of a second switch component Q2 and a second diode D2, wherein the control end of the second switch component Q2 is connected to the MCU control end, the first end is grounded, the second end is connected to the power supply end of the voltage regulator pump through the second diode D2, and the second end is also connected to the other end of the voltage regulator pump. The selection of the second switch component Q2 is similar to that of the first switch component Q1, and will not be repeated here.

[0067] For example, Figure 5 As shown, a voltage detection circuit composed of a third resistor R3 and a fourth resistor R4 is also provided on the water inlet solenoid valve control circuit, wherein one end of the third resistor R3 is connected to the MCU control end, and the other end is respectively connected to the control end of the second switch component Q2 and one end of the fourth resistor R4, and the other end of the fourth resistor R4 is grounded. By detecting the voltage on the fourth resistor R4, the voltage detection signal in the water inlet valve control circuit is determined.

[0068] The embodiment of the present invention independently controls the water inlet solenoid valve control circuit and the pressure regulating pump control circuit, so as to open the water inlet solenoid valve to connect the water path.

[0069] An embodiment of the present invention provides an embodiment of a detection method for a water purification equipment control circuit. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0070] In this embodiment, a detection method for a water purification equipment control circuit is provided, which can be used for a controller of the water purification equipment such as a CPU, a single-chip microcomputer, etc. The water purification equipment control circuit includes a voltage-stabilizing pump control circuit, wherein the control end of the voltage-stabilizing pump control circuit is connected to the controller, and the output end is connected to the power supply end of the voltage-stabilizing pump. Figure 6 is a flow chart of a foreign object detection method for a wireless charging device according to an embodiment of the present invention. Figure 6 As shown, the process includes the following steps:

[0071] Step S601, monitoring water intake of the water purification equipment.

[0072] Specifically, the detection of the user's water-drawing operation can be achieved by setting a pressure switch at the water outlet of the water purification device. In addition, it is also possible to determine whether there is a water-drawing operation of the water purification device by monitoring the flow rate of the water outlet. When there is water flow at the water outlet, it is determined that there is a water-drawing operation of the water purification device. Conversely, when the water flow rate at the water outlet is zero, it is determined that there is no water-drawing operation of the water purification device. The present invention is not limited to this.

[0073] Step S602: when it is detected that the water purification device has no water intake operation, a first drive signal for disconnecting the voltage-stabilizing pump control circuit is output to the control end of the voltage-stabilizing pump control circuit.

[0074] For example, Figure 4 As shown, the first drive signal is a low-level signal. When the MCU control end outputs a low-level signal to the control end of the first switch component Q1, the first switch component Q1 is not turned on, and then the voltage-stabilizing pump power supply end is not powered, and the voltage-stabilizing pump does not start to run. However, when the first switch component Q1 is damaged, the first switch component Q1 may fail to turn on, resulting in the voltage-stabilizing pump power supply end being powered, and the voltage-stabilizing pump starts to run and start producing water, resulting in a large amount of water waste.

[0075] Step S603, obtaining a voltage detection signal of a voltage regulating pump control circuit.

[0076] Specifically, the voltage of the voltage regulating pump control circuit can be detected by providing a voltage detection circuit or a voltage detection device in the voltage regulating pump control circuit. This is only an example, and the present invention is not limited to this.

[0077] Step S604: determining a fault detection result of the voltage regulator pump control circuit based on the voltage detection signal.

[0078] The embodiment of the present invention monitors the water intake of the water purification equipment, outputs a first drive signal to the control end of the voltage-stabilizing pump control circuit to disconnect the voltage-stabilizing pump control circuit when there is no water intake operation, and obtains a voltage detection signal of the voltage-stabilizing pump control circuit, so as to use the voltage detection signal to determine whether there is a fault in the voltage-stabilizing pump control circuit, thereby accurately detecting the operating effectiveness of the water purifier control circuit, reminding the user to cut off the power in time, and avoiding waste of water resources.

[0079] In this embodiment, a detection method for a water purification equipment control circuit is provided, which can be used for a controller of the water purification equipment such as a CPU, a single-chip microcomputer, etc. The water purification equipment control circuit includes a voltage-stabilizing pump control circuit, wherein the control end of the voltage-stabilizing pump control circuit is connected to the controller, and the output end is connected to the power supply end of the voltage-stabilizing pump. Figure 7 is a flow chart of a foreign object detection method for a wireless charging device according to an embodiment of the present invention. Figure 7 As shown, the process includes the following steps:

[0080] Step S701, monitoring water intake of the water purification equipment.

[0081] Specifically, the above step S701 includes:

[0082] Step S7011, obtaining the switch status of the pressure switch provided at the water outlet of the water purification equipment.

[0083] Step S7012, determining whether there is currently a water extraction operation in the water purification device based on the switch status.

[0084] Specifically, when the water faucet of the water purification device is opened, the pressure switch detects a low-pressure signal. At this time, the switch state of the pressure switch is in the open state, and this signal is fed back to the MCU. The MCU determines that there is currently a water-drawing operation of the water purification device based on the signal corresponding to the open state. Conversely, when the water faucet of the water purification device is closed, the pressure switch detects a high-pressure signal. At this time, the switch state of the pressure switch is in the closed state, and this signal is fed back to the MCU. The MCU determines that there is currently no water-drawing operation of the water purification device based on the signal corresponding to the closed state.

[0085] The embodiment of the present invention monitors the switch state of the pressure switch at the water outlet of the water purification device to prevent the user from performing water extraction operation on the water purification device, thereby achieving accurate monitoring of the water extraction operation.

[0086] Step S702: When it is detected that the water purification device has no water intake operation, a first drive signal is output to the control end of the voltage-stabilizing pump control circuit to disconnect the voltage-stabilizing pump control circuit. Figure 6 The relevant description of step S602 is not repeated here.

[0087] Step S703, obtaining a voltage detection signal of the voltage regulating pump control circuit. Figure 6 The relevant description of step S603 is not repeated here.

[0088] Step S704: determining a fault detection result of the voltage regulator pump control circuit based on the voltage detection signal.

[0089] Specifically, the above step S704 includes:

[0090] Step S7041, determining whether the voltage detection signal is a voltage signal.

[0091] Step S7042: when the voltage detection signal is a voltage signal, determine that the fault detection result of the voltage regulating pump control circuit is a circuit failure.

[0092] Step S7043, when the voltage detection signal is a no-voltage signal, determining that the fault detection result of the voltage regulating pump control circuit is that the circuit is valid.

[0093] For example, Figure 4 As shown, when the MCU control end outputs a low-level signal to the control end of the first switch component Q1, the first switch component Q1 is not turned on, and then the voltage regulator pump power supply end is not powered, and the voltage regulator pump does not start to run. However, when the first switch component Q1 is damaged, the first switch component Q1 may fail to turn on, resulting in the voltage regulator pump power supply end being powered, and the voltage regulator pump starts to run and start making water, resulting in a large amount of water waste. Therefore, by judging whether the voltage detection signal is a voltage signal, it can be determined that the fault detection result of the voltage regulator pump control circuit is a circuit failure or a circuit validity.

[0094] The embodiment of the present invention outputs a first drive signal to disconnect the voltage-stabilizing pump control circuit to the control end of the voltage-stabilizing pump control circuit when there is no water intake operation. When the voltage-stabilizing pump control circuit is in effective operation, there is no voltage signal in the circuit. If the voltage detection signal is a voltage signal at this time, it indicates that a component failure or other fault has occurred in the voltage-stabilizing pump control circuit, thereby achieving accurate detection of the failure fault of the voltage-stabilizing pump control circuit; if the voltage detection signal is a no-voltage signal at this time, it indicates that the voltage-stabilizing pump control circuit is in a normal and effective operation state, thereby achieving accurate detection of the effectiveness of the voltage-stabilizing pump control circuit.

[0095] Furthermore, when it is determined that the fault detection result of the voltage-stabilizing pump control circuit is that the circuit is valid, the process returns to the step of monitoring the water intake of the water purification device.

[0096] The embodiment of the present invention realizes continuous detection of the effectiveness of the voltage-stabilizing pump control circuit by continuously monitoring water intake when the voltage-stabilizing pump control circuit is detected to be operating effectively, thereby avoiding the problem of water resource waste caused by device damage and improving user experience.

[0097] Step S705: When it is determined that the fault detection result of the voltage-stabilizing pump control circuit is a circuit failure, a circuit fault alarm is issued to remind the user to cut off the power supply to the water purification device.

[0098] Specifically, a light alarm and / or a voice prompt alarm can be provided on the water purification device by providing an indicator light and / or a sound alarm device. In addition, the fault alarm information can also be sent to a user's mobile phone or other terminal device via a text message or the like to remind the user to cut off the power in time. The present invention is only taken as an example and is not limited thereto.

[0099] The embodiment of the present invention can promptly remind the user to perform power-off processing to avoid wasting water resources by issuing a circuit fault alarm when the voltage-stabilizing pump control circuit fails.

[0100] Furthermore, the water purification equipment control circuit detection method provided by the embodiment of the present invention also includes the following steps:

[0101] Step a1, when it is detected that the water purification equipment has a water intake operation, a second driving signal for turning on the voltage-stabilizing pump control circuit is output to the control end of the voltage-stabilizing pump control circuit to control the voltage-stabilizing pump to be powered on and operate to produce water.

[0102] For example, Figure 4 As shown, when the MCU control end outputs a high level signal to the control end of the first switch component Q1, the first switch component Q1 is turned on, and then the power supply end of the voltage-stabilizing pump is powered, and the voltage-stabilizing pump starts to operate and perform water production operation.

[0103] The embodiment of the present invention realizes automatic water production control by outputting a second drive signal to the control end of the voltage-stabilizing pump control circuit to turn on the voltage-stabilizing pump control circuit when the water purification device is in a water-drawing operation, so that the voltage-stabilizing pump control circuit is turned on and the voltage-stabilizing pump is powered on to produce water.

[0104] The specific working process of the water purification equipment control circuit detection method provided by the embodiment of the present invention will be described in detail below in conjunction with specific application examples.

[0105] In the embodiment of the present invention, in order to solve the problem of the water purifier not stopping due to failure of the control circuit of the pressure-stabilizing pump, firstly, the control circuits of the water inlet solenoid valve and the pressure-stabilizing pump must be completely independent, such as Figure 4 and Figure 5 As shown, it cannot be used as Figure 3 The water inlet solenoid valve and the pressure regulating pump are connected in parallel and linked. When the faucet is turned off, even if the pressure regulating pump control circuit is damaged, the water inlet solenoid valve control circuit is normal, the water inlet solenoid valve is in a closed state, and the pressure regulating pump is only idling. The water supply end is cut off, and no actual water waste occurs. The MCU can realize independent switch control of the two load components without linkage, and prevent the water inlet solenoid valve from being opened at the same time when the water fails, resulting in the water path being connected.

[0106] Furthermore, if Figure 4 As shown, a second resistor R2 is added to the voltage regulating pump control circuit for voltage detection; the device status detection in the voltage regulating pump control circuit can be realized. If there is a voltage signal in the second resistor R2, it is considered that the circuit is powered, and if there is no voltage signal, it is considered that the circuit is in a closed effective state.

[0107] Finally, the control logic is used to determine and remind the hardware circuit failure, such as Figure 8As shown in the figure, when the MCU receives the faucet closing signal indicated by the pressure switch, the MCU gives the corresponding load drive control instruction to close the drive signal of the water inlet solenoid valve control circuit and the voltage regulator pump control circuit; then the voltage signal in the voltage regulator pump circuit is detected by the voltage detection circuit. If the voltage is detected at this time, it is judged that the voltage regulator pump control circuit is abnormal, and a fault is reported to remind the user; if there is no voltage signal, it returns to continue to detect the signal of the pressure switch;

[0108] When the MCU detects that the pressure switch signal is on, it gives the water inlet solenoid valve opening signal and the pressure regulating pump opening signal to carry out normal water production.
