Description

Technical Field

[0001] This patent belongs to the field of new tobacco technology, specifically involving a high-frequency heating smoking device and its heating control method. Background Art

[0002] Electromagnetic heating technology offers advantages such as rapid heating, high thermal energy utilization, and the need for cleaning smoking devices. It utilizes the principle of high-frequency electric heating to convert alternating current into high-frequency current, generating a high-frequency magnetic field. When the magnetic lines of force within the magnetic field act on the heating element, they are cut, generating a large number of small eddy currents, causing the heating element itself to heat rapidly, thereby achieving the purpose of heating. Compared to traditional resistance heating methods, electromagnetic heating solves some consumer pain points, such as uneven heating, difficult cleaning, and easy breakage of sheet heating elements. Furthermore, consumers' demands for the quality of heated cigarette products continue to increase, hoping for a taste and smoking experience closer to traditional cigarettes, as well as a more stable and uniform heating effect. Through optimized design, such as the use of dynamic frequency control and closed-loop temperature control systems, electromagnetic heating technology can better meet consumer requirements for heating effects and quality.

[0003] However, due to the wide variety of heated cigarettes, for example, the type, proportion or processing method of tobacco raw materials will affect the density and humidity of heated cigarettes, and the difference in additives will affect the conductivity and thermal conductivity of heated cigarettes; changes in these parameters directly affect the heating temperature and heating rate required for heated cigarettes, thereby causing changes in their optimal adaptation frequency; different types of heated cigarettes, such as reconstituted tobacco leaves, granular tobacco and cut tobacco, also directly affect the heating temperature. For example, cut tobacco heated cigarettes require a higher heating temperature. At the same time, the frequency of heated cigarettes changes during the smoking process due to the influence of environmental factors. Summary of the Invention

[0004] The purpose of this patent is to provide a high-frequency heating smoking device and a heating control method thereof, so as to achieve the purpose of configuring the optimal heating frequency according to different heated cigarettes and during the smoking process.

[0005] In order to solve the above technical problems, this patent adopts the following technical solutions:

[0006] A high-frequency heating smoking device includes a power module, which is arranged to supply power to the high-frequency heating smoking device during use to heat the heated cigarette to form an aerosol for inhalation; the high-frequency heating smoking device also includes a control module, a frequency conversion module, a detection feedback module and a load module.

[0007] The detection feedback module includes a coupling device and a standing wave detection processing device;

[0008] The coupling device is used to detect the forward transmission signal and the reverse transmission signal during use, and generate a detection signal to the standing wave detection processing device;

[0009] The standing wave detection and processing device is used to process the detection signal and output the processed signal to the control module;

[0010] The control module is used to program and control the frequency conversion module based on the processed signal, so that the frequency conversion module outputs a variable frequency signal;

[0019] When the comparison result shows that the reverse power decreases relative to the forward power, the standing wave ratio decreases, forming a reduced processing signal. The comparator transmits the reduced processing signal to the microcontroller via the sampling device. The microcontroller programs and controls the frequency conversion module based on the processing signal, thereby adjusting the frequency conversion signal to reduce the heating frequency. The comparison result may be that when the reverse power begins to decrease at a value less than or equal to 0.01 times the forward power, the standing wave ratio decreases, forming a reduced processing signal.

[0020] Furthermore, the frequency conversion module includes a frequency synthesis chip, and the frequency synthesis chip outputs a frequency conversion signal through a PLL.

[0021] Furthermore, the frequency synthesis chip can use the professional clock generator MS5351 series.

By connecting an external passive crystal oscillator (25M or 27M) and I 2 C configuration and can realize 3-channel output of any clock from 2.5kHz to 200MHz.

[0022] Furthermore, the sampling device is ADC sampling, and the ADC sampling obtains an increased processing signal and transmits it to the microcontroller, and the microcontroller increases the voltage value of the frequency synthesis chip to increase the heating frequency.

[0023] Furthermore, the microcontroller performs programming control on the frequency synthesis chip via the SPI or I2C communication interface.

[0024] Furthermore, the power module is a rechargeable lithium battery. Alternatively, the power source may be another form of charge storage device, such as a capacitor. The power source may require recharging and may have a capacity that allows for storage of sufficient energy for one or more puffs. The power source may have sufficient capacity to allow for continuous aerosol generation for a period of approximately six minutes, corresponding to the typical time spent smoking a conventional cigarette.

[0025] This patent further provides a heating control method for a high-frequency heating smoking device. The high-frequency heating smoking device includes a power module, which is arranged to supply power to the high-frequency heating smoking device during use to heat the heated cigarette to form an aerosol that can be smoked; the high-frequency heating smoking device also includes a control module, a frequency conversion module, a detection feedback module and a load module.

[0026] In this patent, the term "high-frequency heating" refers to induction heating, a method of heating an electrical conductor (typically metal) using electromagnetic induction. This generates eddy currents in the metal, causing Joule heating of the metal due to electrical resistance. The induction heater consists of an electromagnet through which high-frequency alternating current is passed. If the object has a high magnetic permeability, heat may also be generated due to losses due to magnetic hysteresis. The AC frequency used depends on the size of the object to be heated, the type of metal, the degree of coupling between the heating coil and the object to be heated, and the penetration depth.

[0027] Optionally, high-frequency heating includes electromagnetic heating, radio frequency heating, microwave heating and other smoking device heating methods.

[0028] Preferably, the frequency range of electromagnetic heating is within 10 MHz, preferably 1-3 MHz, 3-6 MHz, 6-7 MHz, 7-8 MHz, 8-9 MHz or 9-10 MHz.

[0029] Preferably, the frequency range of radio frequency heating is 6 to 42 MHz, preferably 10 to 15 MHz, 15 to 20 MHz, 20 to 30 MHz or 30 to 400 MHz.

[0030] Preferably, the microwave heating frequency is in the range of 1 MHz to 15 GHz, preferably in the ISM band, in the range of about 2.4 GHz to about 2.5 GHz and / or having a frequency of about 2.45 GHz.

[0031] In this patent, the term "bidirectional coupler" refers to a passive device used to couple a portion of the transmitted power in a transmission line. Our bidirectional couplers provide the bandwidth, high directivity, and increased power required by designers for their most demanding applications. RF bidirectional couplers typically use two transmission lines placed close together so that energy passing through one is coupled to the other.

[0032] In this patent, the term "logarithmic detector" refers to a circuit device that converts the amplitude of an input signal into an output proportional to the logarithm of the input signal. The basic principle is to use nonlinear components (such as diodes) to implement logarithmic operations. A logarithmic detector can be thought of as a specially designed amplitude measurement device that can provide highly accurate measurements over a wide range of signal strengths.

[0033] In this patent, the term "comparator" refers to an electronic component that outputs different voltage results at the output terminal by comparing the current or voltage at two input terminals.

[0034] In this patent, the term "forward power" refers to the power transmitted from the transmitter to the receiver.

[0035] In this patent, the term "reverse power" refers to the power transmitted from the output end to the transmitter end.

[0036] In this patent, the term "PLL" stands for phase-locked loop (PLL), a negative feedback control system that uses a voltage generated by phase synchronization to tune a voltage-controlled oscillator (VCO) to produce a target frequency. Based on the principle of automatic control, this is a typical feedback control circuit that uses an external reference signal to control the frequency and phase of an oscillating signal within the loop, automatically tracking the output signal frequency to the input signal frequency. It is generally used in closed-loop tracking circuits. It is a method for achieving relatively stable frequency in radio transmissions. It mainly involves a VCO (voltage-controlled oscillator) and a PLL (phase-locked loop integrated circuit). The VCO generates a signal, part of which is output, and the other part is divided and compared with the local oscillator signal generated by the PLL IC. To maintain a constant frequency, the phase difference must remain constant. If the phase difference changes, the voltage at the PLL's voltage output terminal changes, controlling the VCO until the phase difference is restored, achieving phase lock. A closed-loop electronic circuit that maintains a fixed relationship between the frequency and phase of a controlled oscillator and the input signal.

[0037] Furthermore, the high-frequency heating smoking device of this patent and heated cigarettes form an aerosol generating system. Types of heated cigarettes include reconstituted tobacco, granular tobacco, and cut tobacco.

[0038] This patent provides a high-frequency heated smoking device and its heating control method. By setting up a detection and feedback module, it monitors the frequency changes caused by different parameters of the heated cigarette or environmental factors during the smoking process in real time. The control module is set to change the heating frequency through the frequency conversion module based on the information monitored by the detection and feedback module to achieve the optimal smoking temperature configuration. Specifically, the most suitable heating frequency can be automatically configured according to different heated cigarettes and the user's smoking habits to achieve a matching smoking experience and achieve the best smoking taste.

[0039] At the same time, the detection feedback module includes a directional coupling device and a standing wave detection device, which is used to detect the forward power and reverse power of the input and output. The voltage ratio is calculated within the system. When the voltage ratio increases, the ADC sampling obtains an increased signal, and the voltage value of the frequency synthesis chip control end is increased to increase the output frequency; when the voltage ratio decreases, the ADC sampling obtains a decreased signal, and the voltage value of the frequency synthesis chip control end is decreased to reduce the output frequency.

[0040] In addition, the high-frequency heating device provided by this patent has a variable frequency feature, enabling it to provide high-precision frequency signals over a wide frequency range. The frequency synthesis chip is programmed and controlled by the microcontroller of the control module to set the required frequency. The microcontroller is connected to an ADC sampling device and regularly samples the output data of the detection feedback module. Based on the sampled data, it sends instructions to the frequency synthesis chip through a communication interface such as SPI or I2C to achieve accurate correspondence between the frequency and the optimal heating temperature and speed.

[0050] like Figures 1 to 3As shown, this patent provides an embodiment of a high-frequency heating smoking device, including a power module, a control module, a frequency conversion module, a detection feedback module and a load module. The power module is arranged to supply power to the high-frequency heating smoking device during use to heat the heated cigarette to form an aerosol for inhalation; the detection feedback module includes a coupling device and a standing wave detection and processing device; the coupling device is used to detect the forward transmission signal and the reverse transmission signal during use, and generate a detection signal to the standing wave detection and processing device; the standing wave detection and processing device is used to process the detection signal and output the processed signal to the control module; the control module is used to program and control the frequency conversion module based on the processed signal, so that the frequency conversion module outputs a variable frequency signal; the load module is used to change the heating frequency according to the variable frequency signal to dynamically match the inhalation of different heated cigarettes.

[0051] Specifically, the high-frequency heating smoking device of this patent consists of a power module, a frequency conversion module, a control module, a load module, and a detection and feedback module. The power module supplies power to the other modules, the frequency conversion module generates a signal of a specific frequency to drive the load module for adaptive heating, and the detection and feedback module detects the input and output power and controls the frequency conversion control signal based on the comparison of the detection data.

[0052] Specifically, the coupling device includes a bidirectional coupler, which is arranged between the frequency conversion module and the load module, and is used to isolate the signals of the frequency conversion module and the load module and monitor the signals.

[0053] Specifically, the standing wave detection and processing device includes a forward-coupled logarithmic detector, a reverse-coupled logarithmic detector, and a comparator. The forward-coupled logarithmic detector is used to process the forward transmission signal detected by the bidirectional coupler to obtain forward power. The forward transmission signal includes the signal input from the frequency conversion module to the load module. The reverse-coupled logarithmic detector is used to process the reverse transmission signal detected by the bidirectional coupler to obtain reverse power. The reverse transmission signal includes the signal output from the load module to the frequency conversion module. The comparator is arranged to receive and compare the forward power and reverse power, and form a processing signal for the control module based on the comparison result. More specifically, the forward-coupled logarithmic detector and the reverse-coupled logarithmic detector process the signals from the frequency conversion module and the load module respectively, and compare them through the comparator. When it is detected that the reverse power is greater than the forward power, that is, when the ratio increases, the ADC samples an increased signal and increases the voltage value of the frequency synthesis chip control terminal to increase the output frequency. Conversely, when it is unchanged or decreasing, the ADC samples a decreased signal and decreases the voltage value of the frequency synthesis chip control terminal to decrease the output frequency.

[0054] This patent sets up a detection feedback module, which includes a directional coupling device (i.e., a bidirectional coupler) and a standing wave detection device (i.e., a standing wave detection processing device) for detecting the forward power and reverse power of the input and output. The voltage ratio is calculated within the system. When the voltage ratio increases, the ADC samples an increased signal, and the voltage value of the frequency synthesis chip control terminal is increased to increase the output frequency; when the voltage ratio decreases, the ADC samples a decreased signal, and the voltage value of the frequency synthesis chip control terminal is decreased to reduce the output frequency. The bidirectional coupler is used to isolate the signals of the frequency conversion module and the load module.

[0055] Specifically, the control module includes a sampling device and a microcontroller.

[0056] When the comparison result is that the reverse power increases relative to the forward power, the standing wave ratio increases, forming an increased processing signal. The comparator transmits the increased processing signal to the microcontroller through the sampling device. The microcontroller programs and controls the frequency conversion module based on the processing signal, thereby adjusting the frequency conversion signal to increase the heating frequency; wherein the comparison result can be that when the reverse power starts to increase from an increase of less than or equal to 0.01 times the forward power, an increased processing signal is formed.

[0057] When the comparison result shows a decrease in reverse power relative to forward power, the standing wave ratio decreases, generating a reduced processing signal. The comparator transmits the reduced processing signal to the microcontroller via a sampling device. The microcontroller, based on the processing signal, programs and controls the frequency conversion module, thereby adjusting the frequency conversion signal to reduce the heating frequency. The comparison result can be that when the reverse power begins to decrease at a value less than or equal to 0.01 times the forward power, the standing wave ratio decreases, generating a reduced processing signal. The arithmetic unit constitutes a part of the microcontroller. When it detects that the reverse power is greater than the forward power, the comparator compares and determines that the reverse power is greater than the forward power, generating a signal with an increased ratio. The ADC samples the signal and calculates the voltage value at the control terminal of the frequency synthesis chip that needs to be increased through the arithmetic unit.

[0058] Specifically, the frequency conversion module includes a frequency synthesis chip, which outputs a frequency conversion signal via a PLL. More specifically, the frequency conversion module can utilize a specialized frequency synthesis chip capable of generating high-precision frequency signals over a wide frequency range via the PLL. For example, a specialized clock generator such as the MS5351 series can be used. The control module's microcontroller programs the frequency synthesis chip to set the desired frequency.

[0059] Specifically, the sampling device is an ADC. The ADC generates an elevated processed signal and transmits it to a microcontroller, which then increases the voltage of the frequency synthesis chip to increase the heating frequency. More specifically, the microcontroller is connected to the ADC and periodically samples the output data of the detection feedback module. Based on the sampled data, it sends instructions to the frequency synthesis chip via a communication interface such as SPI or I2C, achieving a precise match between the frequency and the optimal heating temperature and speed. Specifically, the microcontroller programs and controls the frequency synthesis chip via the SPI or I2C communication interface.

[0060] Specifically, the power module is a rechargeable lithium battery that ensures a stable DC output voltage. It is also equipped with a corresponding voltage stabilization circuit to cope with voltage fluctuations under different load conditions and provide stable power input for subsequent modules.

[0061] Specifically, the load module includes an electromagnetic induction coil. When the frequency conversion module outputs a frequency conversion signal applied to the load module to change the heating frequency, the electromagnetic induction coil efficiently converts electrical energy into thermal energy through electromagnetic induction based on the heating frequency, thereby regulating the heating temperature of the heated cigarette.

[0062] Working principle: When the heated cigarette 100 is inserted, the detection feedback module in the high-frequency heating smoking device 200 detects the signals of the frequency conversion module and the load module in real time, compares them within the system, and outputs them to the control module through ADC sampling. The control module makes a judgment based on the sampled data and outputs the corresponding frequency conversion signal to the frequency conversion module. After receiving the signal, the frequency conversion module changes the heating frequency of the load module to heat the heated cigarette 100 in the load module.

[0063] This patent further provides a heating control method for a high-frequency heating smoking device. The high-frequency heating smoking device includes a power module, which is arranged to supply power to the high-frequency heating smoking device during use to heat the heated cigarette to form an aerosol that can be smoked; the high-frequency heating smoking device also includes a control module, a frequency conversion module, a detection feedback module and a load module.
