Description

Technical Field

[0001] This utility model relates to the field of moxibustion instrument technology, specifically a control system for an open-flame, smoke-free moxibustion instrument. Background Technology

[0002] A moxibustion device is an auxiliary tool that facilitates the moxibustion process. It combines traditional moxibustion principles with modern electronic technology to provide users with a more convenient and safer moxibustion experience. Utilizing a specific formula of nano- and micro-sized mica, ceramics, nickel alloys, and other vital elements, and incorporating modern technology and physical principles, it integrates a high-temperature oscillation excitation energy zone to release specific infrared energy from the human body. This generates a thermal effect on a large area of ​​acupoints, facilitating absorption by the body, and allows for controllable temperature, energy, power, and penetration.

[0003] A search revealed that patent application number CN201810035080.2 discloses a control system for a vertical moxibustion device. It includes a control unit for controlling the moxibustion device, which sends control commands to the device via a control interface. The control unit also includes a power supply unit, a wireless remote control unit, a temperature sensor, an audio conversion circuit, a Bluetooth transceiver module, and a mode selection circuit. The Bluetooth transceiver module enables data interaction between the control unit and an external device, which in turn sends data to the mode selection circuit via the Bluetooth transceiver module. The mode selection circuit selects between the analog signal from the audio conversion circuit and the data from the Bluetooth transceiver module. The selected data is amplified by an audio driver circuit and then sent to a speaker.

[0004] Most current moxibustion device control systems only focus on the temperature of moxibustion, ignoring the influence of humidity on moxibustion. This is not conducive to the penetration of moxibustion ingredients into the skin, and the moxibustion process produces smoke and harmful gases. If these are not removed in time, they can easily cause respiratory diseases. Therefore, we need to propose a moxibustion device control system with open flame and smoke removal. Utility Model Content

[0005] The purpose of this invention is to provide a control system for an open-flame smoke-removing moxibustion device. Through the design of a temperature and humidity sensor module, the system can monitor the temperature and humidity of the moxibustion environment in real time, which helps the moxibustion ingredients penetrate the skin better, exert their therapeutic effect, and improve the user experience. Through the design of an air quality detection module, the system can monitor the concentration of smoke and harmful gases generated during the moxibustion process in real time, preventing users from inhaling excessive smoke and harmful gases and reducing the risk of respiratory diseases. Through the design of a solenoid valve control module, the system can control the on / off state and speed of internal devices such as the fan and exhaust valve of the moxibustion device, achieving precise airflow adjustment and ensuring timely removal of smoke and harmful gases, thereby solving the problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 This utility model provides a technical solution: a control system for an open-flame smoke-removing moxibustion device, comprising:

[0033] The main control module is used to accept user commands and process data.

[0034] A power management module that provides a stable power supply to the control system;

[0035] The power management module includes a chip U1. An inductor L1 with a 5V output is connected to pin 2 of the chip U1. A capacitor C3 is connected between pins 3 and 4 of the chip U1. A diode D1 and capacitor C1 are connected to both ends of the inductor L1 at pin 4 of the chip U1. A resistor R3 is connected between one end of the inductor L1 and pin 5 of the chip U1. A 24V input is provided at pin 6 of the chip U1. A resistor R1 is connected between pins 6 and 7 of the chip U1.

[0036] Chip U1 is a DC-DC converter, which contains a temperature-compensated bandgap reference source, a comparator, a duty cycle controllable oscillator, a driver, and a high-current output switch. It can realize buck, boost, and inverting functions. In this circuit, it is used to realize the buck function.

[0037] Resistor R1 is a current sampling resistor used to detect the current flowing through chip U1 and to provide overcurrent protection.

[0038] Capacitor C2 is an electrolytic capacitor used for filtering the input power supply, removing high-frequency noise and low-frequency ripple, and making the input voltage more stable.

[0039] Inductor L1 stores energy when the switch is on and releases energy when the switch is off, maintaining the stability of the output voltage; diode D1 provides a freewheeling circuit for inductor L1 during the period when the switch is off, preventing the back electromotive force generated by inductor L1 from damaging the chip or other components.

[0040] Resistors R3 and R4 form a voltage divider circuit, which divides the output voltage V5V and feeds it back to chip U1. Chip U1 adjusts the output according to the feedback voltage to maintain the stability of the output voltage.

[0041] A temperature and humidity detection module for real-time monitoring of the internal temperature and humidity of the moxibustion device;

[0042] The temperature and humidity detection module includes connector J12, chip U12, and chip U22. A capacitor C12 is connected between pins 1 and 2 of chip U12, a capacitor C22 is connected to pin 5 of chip U12, a resistor R12 is connected to pin 2 of chip U22, and pin 2 of chip U22 is connected to pin 2 of connector J12. Pin 3 of chip U22 is connected to pin 3 of connector J12, pin 3 of chip U12 is connected to pin 4 of connector J12, and pin 5 of chip U12 is connected to pin 4 of chip U22.

[0043] Chip U12 is a low-dropout linear regulator that converts the input voltage into a stable output voltage. Chip U22 is a temperature and humidity sensor chip. Connector J12 is used to connect to external devices for serial communication. Resistor R12 ensures that the DATA pin of chip U22 remains at a high level when there is no data transmission.

[0044] An air quality detection module used to detect smoke and odors generated during moxibustion;

[0045] The air quality detection module includes a gas sensor MQ-X, an amplifier U13, and a connector P13. Pins 4 and 6 of the gas sensor MQ-X, pin 3 of the connector P13, and pin 2 of the amplifier U13 are connected. Pin 2 of the connector P13 is connected to pin 1 of the amplifier U13. A grounded resistor R13 and a resistor R23 are connected between pins 4 and 5 of the gas sensor MQ-X. An adjustable resistor RP is connected between pins 4 and 8 of the amplifier U13. A light-emitting diode D13 and a resistor R33 are connected between pins 1 and 8 of the amplifier U13.

[0046] The MQ-X gas sensor is used to detect harmful gases in the air (smoke and odors from moxibustion). The adsorption and chemical reaction of the gas on the sensor surface cause changes in the sensor's resistance value.

[0047] Resistors R13 and R23 form a voltage divider circuit. The change in resistance of the gas sensor MQ-X will cause a change in voltage at the voltage divider node of MQ-X and resistors R13 and R23. This voltage change serves as one of the input signals of the subsequent amplifier U13.

[0048] Amplifier U13 compares the input analog voltage signal with the set reference voltage and outputs high and low level signals. By changing the resistance value of the circuit through the adjustable resistor RP, the reference voltage at the non-inverting input of amplifier U13 is changed, thereby setting the threshold for gas concentration detection.

[0049] LED D13 is connected in series with resistor R33. When amplifier U13 outputs a high level, LED D13 lights up, which can intuitively indicate whether the detected gas concentration exceeds the set threshold.

[0050] An electromagnetic valve control module that controls the internal ventilation and smoke exhaust structure of the moxibustion device to achieve smoke purification and emission;

[0051] The solenoid valve control module includes connector J3, transistor Q1, and MOSFET Q2. A diode D14 is connected between pins 1 and 2 of connector J3. Pin 1 of connector J3 is connected to the source of MOSFET Q2. Resistors R9 and R10 are connected between the drain of MOSFET Q2 and the collector of transistor Q1, and the terminals of resistors R9 and R10 are connected to the gate of MOSFET Q2. Resistor R8 is connected between the base and emitter of transistor Q1, and resistor R7 is connected to the base of transistor Q1.

[0052] Resistor R7 is connected to the input signal DCF, acting as a current limiter to prevent large currents from flowing into the base of transistor Q1, and also dividing the input signal voltage. Transistor Q1 is a preamplifier; when the input signal DCF is high, transistor Q1 conducts, amplifying the input signal DCF to provide drive current for the subsequent field-effect transistors. Resistor R8 acts as a pull-down resistor, ensuring that the base of transistor Q1 remains low when there is no input signal.

[0053] Resistor R9 serves as a current limiter and isolator, transmitting the output signal of transistor Q1 to MOSFET Q2 and limiting the current flowing into the gate of MOSFET Q2. When transistor Q1 is turned on, the gate potential of MOSFET Q2 decreases, and MOSFET Q2 turns on, providing operating current for the solenoid valve. When transistor Q1 is turned off, MOSFET Q2 is turned off, and the solenoid valve is de-energized.

[0054] Diode D14 is connected in parallel with the solenoid valve. When the solenoid valve is de-energized, a reverse electromotive force is generated. Diode D14 provides a discharge circuit for the reverse electromotive force, preventing the reverse electromotive force from damaging components such as the field-effect transistor Q2, and thus protecting the circuit.

[0055] Connector J3 connects to the solenoid valve and is the interface of the solenoid valve. When the circuit is on, the solenoid valve works; when the circuit is off, the solenoid valve stops working.

[0056] A display module that shows the temperature, humidity, and air quality of the moxibustion device and accepts user operation commands;

[0057] The display module includes an OLED display screen. A capacitor C15 is connected between pins 2 and 3 of the OLED display screen. A capacitor C5 is connected between pins 4 and 5 of the OLED display screen. A resistor R65 and a diode VD1 are connected in parallel to pin 14 of the OLED display screen. A resistor R75 and a resistor R105 are connected to pin 15 of the OLED display screen.

[0058] Resistor R65 and diode VD1 form a power protection circuit to prevent reverse connection of the power supply. Capacitor C10 is a power supply filter capacitor to remove high-frequency noise from the power supply. Resistors R85 and R15 act as pull-up resistors or current limiters to ensure stable transmission of control signals and limit the current flowing into the pins of the OLED display.

[0059] The protection module monitors abnormal conditions in the control system and protects the control system.

[0060] The protection module includes a chip U6. Pin 3 of the chip U6 is connected to a series-connected light-emitting diode LED1 and a resistor R16. Pin 2 of the chip U6 is connected to a series-connected light-emitting diode LED2 and a resistor R26. The terminals of the resistors R16 and R26 are connected to pin 8 of the chip U6. Pin 8 of the chip U6 is connected to a parallel-connected capacitor COUT and a battery.

[0061] Resistors R36 and R46 set the charging reference current through a resistor divider, controlling the magnitude of the battery's charging current. Capacitor COUT serves to stabilize the output voltage and filter, ensuring a stable charging voltage is provided to the battery.

[0062] LED1 and LED2 are connected to chip U6 via resistors R16 and R26 respectively, to indicate the battery charging status.

[0063] The temperature and humidity detection module, air quality detection module, solenoid valve control module, display module, and protection module are all electrically connected to the main control module and power management module.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
