Description

Technical Field

[0001] This utility model relates to the field of water disinfection in kitchen faucets. More specifically, this utility model relates to a control circuit system for controlling the electrolysis of municipal water by electrolytic plates. Background Technology

[0002] A faucet is a common name for a water valve, used to control the flow of water and thus saving water. Currently, faucets are typically installed in kitchens and bathrooms. Because tap water supplies may contain bacteria, purification is necessary to reduce bacterial survival. Ozone, also known as active oxygen, has extremely strong oxidizing properties and is recognized worldwide as a broad-spectrum and highly effective disinfectant. Ozone can remove and kill toxic substances and bacteria in air, water, and food, and eliminate odors. For example, patent application number 202111631886.6 discloses an ozone faucet, including a faucet body, an ozone generator, and a mounting base. It uses ozone generated by the ozone generator to disinfect water, making the water cleaner. However, when using an ozone generator or ozone deodorizer to generate ozone and then adding it to municipal water for disinfection, the ozone concentration can only reach 0.2 mg / L. A low ozone concentration will affect the disinfection effect. Summary of the Invention

[0029] This utility model has at least the following beneficial effects:

[0030] This invention directly installs an electrolytic pressure plate in the faucet pipe. The control circuit controls the electrolytic pressure plate to directly electrolyze the municipal water in the faucet pipe to generate ozone, which is then used to sterilize and disinfect the municipal water. This is achieved by adding ozone generated by an ozone generator into the faucet pipe, thereby increasing the ozone concentration in the municipal water. The main control chip in the control circuit can adjust the PWM signal at the signal input terminal OZ_G1 of the constant current control circuit module based on the current data of the electrolytic pressure plate detected by the current detection circuit module (i.e., the current data fed back from the current output terminal OZ_I). This, in turn, switches the enhancement-mode NMOS and enhancement-mode PMOS transistors on and off, ensuring that the power supply to the electrolytic pressure plate is in a relatively constant current output state. The main control chip can also calculate the real-time TDS value of the municipal water based on the voltage data detected by the voltage detection circuit module. In summary, this invention uses a single circuit—the control circuit—to replace the traditional ozone faucet method that requires both an ozone generator and a faucet control box to produce ozone water. It can also detect the TDS value of municipal water without the need for a TDS detection module. Furthermore, the ozone water concentration produced by this control circuit can reach over 1 mg / L, far exceeding the concentration of commercially available ozone faucets. Additionally, the smaller size of this control circuit facilitates the structural design of the ozone faucet control box, allowing for a smaller and lower-cost design, making it widely applicable to faucet products in the electronic disinfection field.

[0044] like Figures 1-8 As shown, this utility model embodiment provides a control circuit system for controlling the electrolysis of municipal water by an electrolytic press. The electrolytic press is installed in a faucet pipe, and the electrolytic press is electrically connected to a control circuit to generate ozone by electrolyzing the municipal water in the faucet pipe. The control circuit includes:

[0045] Main control chip;

[0046] A constant current control circuit module is electrically connected to the positive terminal of the electrolytic platen to provide constant current output to the electrolytic platen. The constant current control circuit module is provided with a signal input terminal OZ_G1 for PWM signal input.

[0047] A current detection circuit module, which is connected in series with the constant current control circuit module, is used to detect the current data of the electrolytic pressing plate. The current output terminal OZ_I of the current detection circuit module is connected to the main control chip. The main control chip adjusts the PWM signal input to the signal input terminal OZ_G1 according to the collected current data, so that the power supply of the electrolytic pressing plate is in a constant current output state.

[0048] A voltage detection circuit module is electrically connected to the positive terminal of the electrolytic platen and is used to detect the voltage data of the electrolytic platen. The voltage output terminal OZ_V of the voltage detection circuit module is connected to the main control chip.

[0049] In the above embodiment, an electrolytic plate is installed in the faucet pipe. When the faucet is turned on, water flows through the faucet pipe and passes through the electrolytic plate. Under the control of the control circuit, the electrolytic plate electrolyzes the water in the faucet pipe to generate ozone, which then disinfects the municipal water. The control circuit includes a main control chip, a constant current control circuit module, a current detection circuit module, and a voltage detection circuit module. The current detection circuit module can detect the current data of the electrolytic plate, thereby causing the main control chip to change the PWM signal input to the signal input terminal OZ_G1 according to the collected current data. Through the constant current control circuit module, the power supply to the electrolytic plate is ensured to be in a constant current output state.

[0050] In specific implementation, the main control chip calculates the TDS value of municipal water based on the acquired voltage data of the electrolytic pressing sheet. The relationship between the voltage data and the TDS value is as follows: Where y is the TDS value and x is the voltage data of the electrolytic tablet. TDS is an abbreviation for Total Dissolved Solids, which mainly reflects the concentration of ions such as Ca2+, Mg2+, Na+, and K+ in water. TDS values ​​are commonly used to measure the purity of purified water. The voltage detection circuit module can detect the voltage data of the electrolytic tablet. In this embodiment, it was found that there is a certain relationship between the detected voltage data and the TDS value. Based on the formula relating the voltage data and the TDS value, the main control chip can calculate the TDS value of municipal water based on the acquired voltage data of the electrolytic tablet. Figure 7 As shown, the horizontal axis represents voltage data, and the vertical axis represents TDS value. Therefore, in this embodiment, it is not necessary to set up a TDS detection module or TDS detector to detect the TDS value of municipal water. Figure 9 The document presents detection data of electrolyzing municipal water using the control circuit in this embodiment. The data shows that the ozone concentration produced by the control circuit can reach more than 1 mg / L, and there is a certain relationship between the voltage data and the TDS value.

[0051] In one specific embodiment, the control circuit system for controlling the electrolysis of municipal water by electrolytic pressing tablets further includes a control panel, the interface of which is bidirectionally connected to the main control chip, wherein the acquired TDS value is displayed on the control panel.

[0052] In the above embodiments, the main control chip communicates bidirectionally with the control panel via the control panel interface using methods such as IIC and UART. The TDS value acquired by the main control chip can also be directly displayed on the control panel's screen, greatly improving the user's water usage experience. Figure 5The control panel interface circuit diagram is shown in the figure.

[0053] In one specific embodiment, the control circuit system for controlling the electrolysis of municipal water by electrolytic pressing tablets, such as Figure 1 As shown, the constant current control circuit module specifically includes:

[0054] A DC power input module includes: a DC power supply interface; an electrolytic capacitor EC1, one end of which is connected to the DC power supply interface and the other end is grounded to filter the input power;

[0055] An enhancement-mode NMOS transistor has a gate terminal OZ_G1 as its signal input terminal. A Zener diode Q1 is connected between the source and drain of the enhancement-mode NMOS transistor. The source of the enhancement-mode NMOS transistor is connected to the other end of the electrolytic capacitor EC1.

[0056] An enhancement-mode PMOS transistor has its gate connected to the drain of an enhancement-mode NMOS transistor. A Zener diode Q2 is connected to the source and drain of the enhancement-mode PMOS transistor. The source of the enhancement-mode PMOS transistor is connected to the positive terminal of the electrolytic plate. The drain of the enhancement-mode PMOS transistor is a DC power supply interface.

[0057] An electrolytic capacitor power supply module has one end connected to the positive terminal of the electrolytic capacitor and the other end grounded. An electrolytic capacitor EC2 is also provided between the positive and negative terminals of the electrolytic capacitor power supply module to store and filter the power supply output to the electrolytic capacitor. One end of the electrolytic capacitor EC2 is connected to both the source of the enhancement-mode PMOS transistor and the positive terminal of the electrolytic capacitor.

[0058] The current detection circuit module includes: a connection point between the other end of the electrolytic capacitor EC2 and the negative terminal of the electrolytic pressure plate power supply module, one path of which is connected to a parallel resistor R1 and a resistor R2, the other end of which is grounded; the other path is connected to a resistor R5, the other end of which is connected to a capacitor C6, the other end of which is grounded; and a current output terminal OZ_I is provided between the resistor R5 and the capacitor C6.

[0059] In specific configurations, to protect the source, gate, and drain of the enhancement-mode NMOS and enhancement-mode PMOS transistors, a resistor R4 is provided between the source and gate of the enhancement-mode NMOS transistor, and a resistor R3 is provided between the signal input terminal OZ_G1 and the gate of the enhancement-mode NMOS transistor; a resistor R21 is provided between the gate of the enhancement-mode PMOS transistor and the drain of the enhancement-mode NMOS transistor, and a resistor R20 is provided between the drain of the enhancement-mode PMOS transistor and the gate of the enhancement-mode PMOS transistor.

[0060] In the above embodiment, by adjusting the PWM signal to turn the enhanced NMOS transistor and the enhanced PMOS transistor on / off, a discrete constant current supply is formed to power the electrolytic capacitor. Figure 1 In the diagram, OZONE+ indicates the positive terminal of the electrolytic capacitor, DC-IN is the DC power supply interface, J1 is the external power supply interface, and OZ-Power is the electrolytic capacitor power supply module. (Further details are provided in the appendix.) Figure 1 The optimal values ​​for various electrical components, such as resistors and capacitors, are given in the paper.

[0061] In one specific embodiment, the control circuit system for controlling the electrolysis of municipal water by electrolytic pressing tablets includes a voltage detection circuit module comprising:

[0062] Capacitor C7 has one end connected to both resistors R14 and R15. The other end of resistor R14 is connected to the positive terminal of the electrolytic plate, and the other end of resistor R15 is connected to the other end of capacitor C7. The other end of capacitor C7 is grounded.

[0063] The voltage output terminal OZ_V is provided between resistor R14 and resistor R15.

[0064] In one specific embodiment, the control circuit system for controlling the electrolysis of municipal water by electrolytic pressing tablets, such as Figure 2 As shown, it also includes a solenoid valve drive circuit, which is an H-bridge circuit, used to control a pulse-type solenoid valve installed on the faucet pipe. The solenoid valve drive circuit is electrically connected to the main control chip.

[0065] In the above embodiment, the solenoid valve drive circuit is an H-bridge circuit, such as... Figure 2 As shown, the T1016H / SOT23-6 chip is used. The main control chip can control the solenoid valve drive circuit to switch the solenoid valve on and off, thereby controlling the opening and closing of the faucet.

[0066] In one specific embodiment, the control circuit system for controlling the electrolysis of municipal water by the electrolytic press further includes a flow Hall sensor, the interface of which is connected to the main control chip. The flow Hall sensor is installed in the faucet pipe. The main control chip scans and detects the Hall flow through the flow Hall sensor interface to detect whether water has passed through the electrolytic press and prevent the electrolytic press from working under no-load conditions.

[0067] In the above embodiment, specifically, the flow Hall sensor is positioned closer to the faucet outlet than the electrolytic pressure plate. Water in the faucet pipe first passes through the electrolytic pressure plate and then through the flow Hall sensor. This ensures that the main control chip, through the flow Hall sensor interface, can scan and detect the Hall flow rate, detecting whether water has passed through the electrolytic pressure plate. When a low water flow is detected, the main control chip shuts off Zener diodes Q1 and Q2 via the signal input terminal OZ_G1, preventing the electrolytic pressure plate from operating under no-load conditions. Figure 6 The diagram shows the interface circuit diagram of the flow Hall sensor.

[0068] In one specific embodiment, the control circuit system for controlling the electrolysis of municipal water by electrolytic pressing tablets, such as Figure 3 As shown, it also includes a power supply circuit for supplying power to the main control chip, the control panel, the flow Hall sensor, and the solenoid valve drive circuit. The power supply circuit includes:

[0069] DC power supply interface;

[0070] Diode D1, one end of which is connected to the DC power supply interface;

[0071] The LDO chip has its voltage input terminal VIN connected to the other end of the diode D1;

[0072] Electrolytic capacitor EC3 and capacitor C2 are connected in parallel. One end of the parallel connection of electrolytic capacitor EC3 and capacitor C2 is connected to both the diode D1 and the input terminal VIN of the LDO chip, and the other end is grounded.

[0073] Electrolytic capacitor EC4 and capacitor C3 are connected in parallel. One end of the parallel connection of electrolytic capacitor EC4 and capacitor C3 is connected to the output terminal VOUT of the LDO chip, and the other end is grounded.

[0074] The grounding port of the LDO chip is grounded.

[0075] In the above embodiment, the LDO chip is a power regulator chip capable of providing a stable DC voltage. A power adapter is used to power the power supply circuit, constant current control circuit module, current detection circuit module, and voltage detection circuit module. The power supply circuit also powers the main control chip, the control panel, the flow Hall sensor, and the solenoid valve drive circuit.

[0076] In summary, the control circuit system for controlling the electrolysis of municipal water using electrolytic pressing tablets in this embodiment has the functions of generating ozone, controlling the faucet, and detecting TDS. It can replace the control method of ozone faucets on the market, which requires two circuits—an ozone generator and a faucet control box—to produce ozone water using a single circuit. Simultaneously, it can detect the TDS value of municipal water without the need for a TDS detection module. Furthermore, the ozone water concentration generated by this control circuit can reach over 1 mg / L, far exceeding the concentration of commercially available ozone faucets. In addition, the control circuit is smaller, which facilitates the structural design of the ozone faucet control box, allowing for a smaller and lower-cost control box. Therefore, this embodiment achieves higher ozone water concentration at a lower cost, simplifies structural complexity, and reduces the space occupied by the control box. Thus, it can be widely used in faucet products in the field of electronic disinfection.
