Description

Technical Field

[0001] This invention belongs to the field of water purification equipment technology, specifically relating to an intelligent control system and method for a flow-through type active oxygen sterilization faucet. Background Technology

[0002] A flow-generating ozone sterilizing faucet is a kitchen and bathroom appliance that generates ozone (vital oxygen) in real time as water flows through it. It purifies water using ozone, functioning as an ozone water purifier. During operation, the faucet produces ozone through an internal electrolytic load. The ozone dissolves in water, forming oxygenated water. The strong oxidizing properties of ozone destroy bacterial cell membranes and decompose pesticide molecules and odor substances, resulting in sterilization and pesticide residue removal. Furthermore, the ozone is quickly reduced to oxygen, causing no secondary pollution.

[0003] Current flow-through ozone generator faucets suffer from unstable operation, primarily due to problems with their control circuitry and logic. Firstly, an unstable power supply causes the electrolytic load power for ozone generation to fluctuate wildly, resulting in large concentration fluctuations. Secondly, in the absence of water or with insufficient water, the electrolytic load lacks protection and adjustment, making it prone to malfunction, and the ozone concentration cannot be controlled.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] In one embodiment, an intelligent control system for a flow-through oxygen-generating sterilization faucet is provided. The intelligent control system for the flow-through oxygen-generating sterilization faucet includes a battery, a charging module, a main control module, a power conversion module, a drive module, a debugging interface module, a touch control module, an alarm module, and a status indicator module. The charging module is electrically connected to the battery for charging the battery. The battery is a lithium battery for powering the flow-through oxygen-generating sterilization faucet.

[0025] The main control module, power conversion module, debugging interface module, alarm module, and status indicator module are all electrically connected to the battery for battery power supply. The main control module is the control center of the entire system. The drive module is electrically connected to the power conversion module so that the power conversion module can boost the battery output voltage and then supply power to the electrolytic load of the overcurrent generating active oxygen sterilization faucet through the drive module. The power conversion module and the drive module are equipped with circuits for collecting working signals, thereby ensuring the stability of the power supply to the electrolytic load of the overcurrent generating active oxygen sterilization faucet and timely adjustment of its working status.

[0026] The touch control module is electrically connected to the main control module and is used to input signals to the main control module to control the working mode; the alarm module and the status indicator module, under the control of the main control module, emit corresponding light status or sound prompts to inform the working status of the flow-through generating active oxygen sterilization faucet.

[0027] like Figure 1 As shown, the charging module includes a charging chip U2, which is a TP4056 constant current / constant voltage linear charger. The charging chip U2 is electrically connected to the charging interface DCIN and to the power supply interfaces BAT and BAT-1 of two batteries. The charging chip U2 can charge the batteries.

[0028] like Figure 2 As shown, the main control module includes a main control chip U1, which controls the operation of other modules in the system. Figure 1 In this circuit, the charging module is electrically connected from the CHRG and STDY pins of the charging chip U2 to the CHRG and STDY pins of the main control chip U1. The main control chip U1 controls the corresponding indicator lights to illuminate based on the level states of the CHRG and STDY pins. The CHRG pin's high and low levels indicate the charging process status, while the STDY pin's high and low levels indicate the battery's full charge status. The battery's output pin VBAT is electrically connected to the VBAT pin of the main control chip U1 to supply power to VBAT.

[0029] Combination Figure 3As shown, the power conversion module of the intelligent control system of the flow-through oxygen generator sterilization faucet is used to boost the battery output and stabilize the operation of the flow-through oxygen generator sterilization faucet by sampling, analyzing and regulating the current.

[0030] Combination Figure 2-3 As shown, the front-end input signal HVPWM of the power conversion module comes from pin 12 of the main control chip U1 of the main control module. The input signal HVPWM is a pulse signal provided by pin 12 of the main control chip U1. The input signal HVPWM is used to control the conduction of transistors Q28 and Q29. Transistor Q28 is an NPN transistor and transistor Q29 is a PNP transistor. Transistors Q28 and Q29 form a totem pole circuit that controls the on / off state of MOSFET Q21. Transistor Q28 is powered through the battery output terminal VBAT. MOSFET Q21 is used to control the inductor L21 to store and release electrical energy.

[0031] When the input signal HVPWM is high, the signal is current-limited by resistor R21, which turns on the Zener diode D22, thereby providing a stable base voltage for transistor Q28. Transistor Q28 turns on, which in turn charges and turns on the gate of MOSFET Q21. When the input signal HVPW is low, transistor Q28 turns off, and transistor Q29 turns on, which turns off the gate of MOSFET Q21.

[0032] like Figure 3 As shown, the power conversion module has a combined circuit consisting of inductor L21 and diode D21 that can generate a voltage multiplier. When MOSFET Q21 is turned on, inductor L21 is charged. Inductor L21 is charged through the output terminal VBAT of the battery. Since the input is DC, the current in inductor L21 increases linearly at a certain rate. As the inductor current increases, some energy is stored in the inductor.

[0033] When MOSFET Q21 is turned off, inductor L21 discharges. Due to the current holding characteristic of inductor L21, the current flowing through inductor L21 does not immediately become 0, but slowly changes from the value when it is fully charged to 0. Since the circuit originally formed by MOSFET Q21 is now broken, inductor L21 can only discharge through the new circuit. That is, inductor L21 begins to charge capacitors C22, C23, and C24, and the voltage across capacitors C22, C23, and C24 increases. At this point, the voltage is already higher than the battery input voltage VBAT, and the voltage boost is complete.

[0034] Diode D21 is used to prevent capacitors C22, C23 and C24 from discharging to ground. The terminal HV at the rear end of diode D21 is the output voltage terminal after the voltage boost is completed. Capacitors C22, C23 and C24 can stabilize the voltage.

[0035] like Figure 3 As shown, the power conversion module includes a real-time sampling circuit consisting of resistors R32 and R22, and capacitor C29. The terminal I_INTEST between resistor R22 and capacitor C29 is the current detection terminal. Figure 1 As shown, the I_INTEST terminal is electrically connected to the I_INTEST terminal (pin 3) of the main control chip U1 of the main control module. The current flowing through the MOSFET Q21 will generate a voltage drop across the sampling resistor R22. This voltage drop is output to the main control chip U1 through the I_INTEST terminal. The main control chip U1 samples, analyzes, and regulates the current to keep the output voltage HV stable, thereby ensuring the stable operation of the overcurrent generating active oxygen sterilization faucet.

[0036] Combination Figure 4 As shown, the drive module of the intelligent control system of the flow-through generating active oxygen sterilization faucet is an H-bridge, which is used to control the operation of the electrolytic load of the flow-through generating active oxygen sterilization faucet and realize the polarity conversion function. At the same time, it protects the ozone water purifier from damage in waterless, water-scarce, and high-temperature environments.

[0037] like Figure 1 and Figure 4 As shown, the drive module includes transistors Q22, Q23, Q24, Q25, Q26, and Q27, which are switched on by a switching mechanism. The base of transistor Q22 is electrically connected to pin IF of the main control chip U1 of the main control module via a resistor, and the base of transistor Q23 is electrically connected to pin IB of the main control chip U1 of the main control module via a resistor R24. The ANION terminal is electrically connected to the electrolytic load of the current-generating active oxygen sterilization faucet.

[0038] When the main control chip U1 of the main control module outputs a high level at pin IF, transistor Q22 is turned on, and the gate of MOSFET Q24 is at a low level, causing MOSFET Q24 to turn on. The input terminal of MOSFET Q24 is connected to the boosted voltage output terminal HV of the power conversion module. Pin 1 of the ANION terminal is the positive input (i.e., the voltage output terminal HV). Since the gate of MOSFET Q27 is connected to the voltage output terminal HV through resistor R28, it remains in the on state, causing pin 2 of the ANION terminal to be grounded through MOSFET Q27. Thus, pins 1 and 2 of the ANION terminal are turned on, and the electrolytic load of the overcurrent generation active oxygen sterilization faucet generates ozone.

[0039] When the main control chip U1 of the main control module outputs a high level at pin IB, transistor Q23 is turned on, and the gate of MOSFET Q25 is at a low level, causing MOSFET Q25 to turn on. The input terminal of MOSFET Q25 is connected to the boosted voltage output terminal HV of the power conversion module. Pin 2 of the ANION terminal is the positive input (i.e., the voltage output terminal HV). Since the gate of MOSFET Q26 is connected to the voltage output terminal HV through resistor R27, it remains on, causing pin 1 of the ANION terminal to be grounded through MOSFET Q26. Thus, pins 1 and 2 of the ANION terminal are turned on, and the polarity of the electrolytic load of the overcurrent generation active oxygen sterilization faucet is reversed. At this time, no ozone is generated. The purpose of the polarity reversal is to remove the scale on the electrolytic load.

[0040] like Figure 4 As shown, the drive module also includes a circuit for detecting the output voltage, consisting of resistors R29 and R26 and capacitor C27. The voltage detection pin HVTEST is located between resistor R26 and capacitor C27 to determine whether the voltage HV is stable. The drive module also includes a circuit for detecting the operating current, consisting of resistors R31 and R25 and capacitor C28. The current detection pin ITEST is located between resistor R25 and capacitor C28 to determine whether the operating current of the electrolytic load is within the normal operating range. When there is no water or a water shortage, the operating voltage and current of the electrolytic load will become abnormal. By using these voltage and current parameters, the ozone water purifier is protected in the event of no water or a water shortage, preventing damage.

[0041] Combination Figure 5 As shown, the status indicator module of the intelligent control system for this flow-through oxygen-generating sterilizing faucet includes 16 light-emitting diodes (LEDs): D1, D2, D3, D4, D5, D6, D7, D8, D9, D10, D11, D12, D13, D14, D15, and D16. Among these, 8 are red LEDs and 8 are green LEDs. The positive terminals of all 16 LEDs are connected to the battery output terminal VBAT. The negative terminals of the 8 green LEDs are connected to LED-G of the main control chip U1 via resistor R7, and the negative terminals of the 8 red LEDs are connected to LED-R of the main control chip U1 via resistor R8. This control module illuminates the corresponding LEDs based on the status of the flow-through oxygen-generating sterilizing faucet.

[0042] Combination Figure 6As shown in (A), the debugging interface module of the intelligent control system of the flow-through oxygen-generating sterilizing faucet has pin 2 IISCL electrically connected to the IISCL terminal (pin 6) of the main control chip U1, pin 3 IISDA electrically connected to the IISDA terminal (pin 5) of the main control chip U1, pin 1 electrically connected to the battery output terminal VBAT, and pin 4 grounded. This debugging interface module can be used for firmware upgrades.

[0043] Combination Figure 6 As shown in (B), the touch control module of the intelligent control system of the flow-through generating active oxygen sterilization faucet generates an input signal (TK1) through a touch switch. The input signal terminal TK1 is electrically connected to the TK1 terminal (pin 1) of the main control chip U1. It is used to control the working mode by long press, tap, etc.

[0044] Combination Figure 6 As shown in (C), the alarm module of the intelligent control system of the flow-through generating active oxygen sterilization faucet includes a buzzer BZ2. The positive terminal of the buzzer BZ2 is electrically connected to the output terminal VBAT of the battery, and the negative terminal is grounded through a transistor Q2. The base of the transistor Q2 is electrically connected to the BELL terminal (pin 2) of U1 through a resistor R16, which is used to emit sound to remind the user according to the working status during operation.

[0045] In one embodiment, a flow-through ozone generator is provided, which is equipped with the intelligent control system of the flow-through ozone generator described in the previous embodiment. This flow-through ozone generator has the advantages of stable operation and stable ozone concentration.

[0046] In one embodiment, an intelligent control method for a flow-through oxygen-generating sterilizing faucet is provided. This method is based on the intelligent control system for the flow-through oxygen-generating sterilizing faucet in the previous embodiment, and includes: The charging module enables intelligent charging management of the battery. The charging chip U2 used in the charging module is the TP4056 charging chip, whose charging logic can protect the battery while achieving fast charging.

[0047] The power conversion module boosts the battery output voltage, and then the drive module supplies power to the electrolytic load of the overcurrent-generating active oxygen sterilization faucet based on the increased voltage. The power conversion module is based on a voltage multiplier circuit composed of inductor L21 and diode D21, which can increase the battery output voltage so that the voltage meets the working requirements of the electrolytic load.

[0048] The current signal is collected by the current sampling terminal I_INTEST on the power conversion module and sent to the main control module. The main control module performs current sampling, analysis, and regulation to provide a stable operating power supply for the overcurrent generating active oxygen sterilization faucet. Because the power conversion module has a current sampling terminal I_INTEST for collecting current signals, the main control module can determine the stability of the power conversion module's operation, thereby ensuring a stable operating power supply for the electrolytic capacitor.

[0049] The voltage detection terminal HVTEST and current detection terminal ITEST on the drive module collect signals in real time and send them to the main control module. The main control module determines the working status of the electrolytic load based on the collected current and voltage signals, protecting the flow-through ozone generator faucet from water shortages and enabling low-power standby when not in operation. When there is no water, the current of the electrolytic load will be abnormal, triggering the main control module's power-off protection. The current of the electrolytic load will also change when there is a water shortage, triggering the main control module to adjust and match the supply current with the water flow, thus matching the amount of ozone generated by electrolysis with the water output of the flow-through ozone generator faucet.
