Description

Technical Field

[0001] This application relates to the field of microwave technology, and in particular to an electronic cigarette based on a microwave solid-state source. Background Technology

[0002] In microwave solid-state source-based e-cigarette technology, the reverse power detection circuit is a crucial component of the microwave solid-state source assembly, playing a key role in resonant frequency lookup and cigarette heating status detection. Current e-cigarette products typically use logarithmic detectors (such as the AD8314) for reverse power detection. Its basic operation is as follows: the logarithmic detector detects the echo power signal and converts it into a voltage signal; this voltage signal is then converted to an analog-to-digital converter (ADC) and input to a microprocessor for analysis and control. While existing solutions meet basic power detection requirements, they still have the following drawbacks: Logarithmic detector chips like the AD8314 are expensive and require external circuitry, resulting in high overall circuit costs and making them unsuitable for miniaturized products like e-cigarettes. The voltage output resolution is low, and the resonance quality resolution is insufficient. The output voltage change is small under good and bad resonance conditions, making it impossible to accurately determine the resonance state. For example, when the resonant cavity is in its worst state (total reflection) and best state (extremely low reflection), the output voltage difference of the power detection unit is very small, resulting in insufficient resolution and affecting the accuracy of resonance quality analysis.

Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] like Figure 1 As shown, one embodiment of this application provides a microwave solid-state source electronic cigarette, which includes an RF solid-state source module 100 that receives power signals and outputs RF signals to the cigarette heating resonant cavity 300. The RF solid-state source module 100 includes: a boost unit 101, which receives and boosts the power signals from the battery 400; an RF solid-state source 102, connected to the boost unit 101, which receives the electrical signals sent by the boost unit 101 and generates RF signals; and a circulator 104, connected to the RF solid-state source 102, which receives and stabilizes the RF signals and outputs them to the cigarette heating resonant cavity 300. A thermal resonant cavity 300; a coupler 105, connected to a circulator 104, receives the echo signal reflected back from the cigarette heating resonant cavity 300, the echo signal including a first echo signal and a second echo signal, the coupler 105 transmits the first echo signal to the load; a power detection unit 106, connected to the coupler 105, receives the second echo signal and converts the second echo signal into a voltage signal; a voltage curve shaping and conversion unit 107, connected to the power detection unit 106, receives the voltage signal and converts the voltage signal into a voltage curve.

[0038] In this embodiment, it should be noted that the boost unit 101 receives the power signal from the battery 400 and boosts it to provide a stable voltage to the RF solid-state source 102. The RF solid-state source 102 is connected to the boost unit 101, receives the boosted electrical signal, and generates an RF signal. The circulator 104 is connected to the RF solid-state source 102, receives and stabilizes the RF signal, and outputs it to the cigarette heating resonant cavity 300. The coupler 105 is connected to the circulator 104, receives the echo signal reflected from the cigarette heating resonant cavity 300, and divides the echo signal into: a first echo signal, which is transmitted to the load to maintain system stability; and a second echo signal, which is transmitted to the power detection unit 106 for resonance quality detection. The power detection unit 106 is connected to the coupler 105, receives the second echo signal, and converts it into a voltage signal. The voltage curve shaping and conversion unit 107 is connected to the power detection unit 106, and optimizes the voltage output curve to improve signal resolution, accuracy, and efficiency for subsequent analysis and processing.

[0039] The technical solution implemented in this embodiment can achieve low cost and miniaturization by using a microwave diode detection circuit, perfectly matching electronic cigarette consumer electronics applications. A voltage curve shaping and conversion unit 107 is added after the power detection unit 106. The conversion circuit eliminates bottom noise in the converted detection signal. Under conditions of severe reflection (worst-case scenario such as total reflection) and ideal reflection (such as extremely low reflection), the output voltage difference of the power detection unit 106 is increased to over 2V, significantly improving resolution and recognition accuracy, thereby enhancing the accuracy of resonant cavity state detection.

[0040] In an optional embodiment, the RF solid-state source module 100 further includes: a coprocessor 103 connected to the voltage curve shaping and conversion unit 107 for receiving voltage curves, and connected to the boost unit 101 and the RF solid-state source 102 for sending control signals to the boost unit 101 and the RF solid-state source 102.

[0041] In this embodiment, the coprocessor 103 is connected to the voltage curve shaping and conversion unit 107 and is responsible for receiving the shaped and converted voltage curves. These voltage curves reflect the resonance quality of the cigarette heating resonant cavity 300, and the coprocessor 103 evaluates the operating state of the resonant cavity by analyzing these curves. Simultaneously, the coprocessor 103 is also connected to the boost unit 101 and the radio frequency solid-state source 102, sending control signals to these two units. Based on the received voltage curves and the system's operating requirements, the coprocessor 103 can dynamically adjust the output voltage of the boost unit 101 and the output power of the radio frequency solid-state source 102 to optimize system performance.

[0042] By implementing the technical solution of this embodiment, the introduction of the coprocessor 103 enables intelligent control and adjustment of the system, improving its flexibility and adaptability. The coprocessor 103 can dynamically adjust the operating states of the boost unit 101 and the RF solid-state source 102 based on real-time voltage curve data, thereby optimizing the overall system performance. Through precise control of the generation and transmission of RF signals, the system can heat the cigarette more efficiently, enhancing the user experience of electronic cigarettes.

[0043] In an optional embodiment, the RF solid-state source module 100 further includes an attenuator unit 108 connected between the coupler 105 and the power detection unit 106 to reduce the strength of the second echo signal before transmitting it to the power detection unit 106.

[0044] In this embodiment, it should be noted that the attenuator unit 108 is connected between the coupler 105 and the power detection unit 106, and its main function is to reduce the strength of the second echo signal. By reducing the signal strength, the attenuator can prevent the power detection unit 106 from saturating or being damaged due to an excessively strong input signal.

[0045] By implementing the technical solution of this embodiment and introducing the attenuator unit 108, the system can operate more stably, avoiding damage or malfunctions caused by signal overload. It also allows the power detection unit 106 to operate within its optimal operating range, thereby improving measurement accuracy and reliability. Furthermore, it protects the power detection unit 106 from excessively strong signals, extending its service life.

[0046] like Figure 2 As shown, in one specific embodiment, the attenuator unit 108 includes: a first resistor R1, a second resistor R2 and a third resistor R3. The first resistor R1 is connected in series between the coupler 105 and the signal ground. One end of the second resistor R2 is connected to the coupler 105, and the other end is connected to the third resistor R3 and the power detection unit 106 respectively. The other end of the third resistor R3 is connected to the signal ground.

[0047] The power detection unit 106 includes: a first capacitor C1, a second capacitor C2, a first diode D1 and a fourth resistor R4, wherein the first capacitor C1 is connected in series between the second resistor R2 and the input terminal of the first diode D1, the second capacitor C2 and the fourth resistor R4 are connected in series between the output terminal of the first diode D1 and the signal ground, and the second capacitor C2 and the fourth resistor R4 are connected in parallel.

[0048] The voltage curve shaping and conversion unit 107 includes: a first operational amplifier U1, a first power supply terminal, a second power supply terminal, a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, and a third capacitor C3. The fifth resistor R5 and the sixth resistor R6 are connected in series between the first power supply terminal and signal ground; the sixth resistor R6 and the seventh resistor R7 are connected in series between the first power supply terminal and the output terminal of the first operational amplifier U1; the fifth resistor R5 is connected in series between signal ground and the inverting input terminal of the first operational amplifier U1; the non-inverting input terminal of the first operational amplifier U1 is connected to the output terminal of the first diode D1; the output terminal of the first operational amplifier U1 is connected to the coprocessor 103; the positive power supply terminal of the first operational amplifier U1 is connected to the second power supply terminal; and a third capacitor C3 is connected in series between the second power supply terminal and signal ground.

[0049] In this embodiment, it should be noted that the attenuator forms a π-type attenuation network, which can effectively reduce the signal strength. The power detection unit 106 rectifies and filters the second echo signal, converting the radio frequency signal into a DC voltage signal. The voltage curve shaping and conversion unit 107 amplifies and filters the DC voltage signal, converting the rectified voltage signal into a voltage curve that is easier to process.

[0050] In implementing the technical solution of this embodiment, the coupler 105 receives the second echo signal reflected back from the cigarette heating resonant cavity 300. The attenuator unit 108 reduces the signal strength to prevent the power detection unit 106 from overloading. The power detection unit 106 converts the attenuated radio frequency signal into a voltage signal, and the voltage curve shaping and conversion unit 107 shapes the voltage signal to improve signal resolution. By precisely controlling and detecting the transmission and reflection of the radio frequency signal, the system can more effectively transfer energy to the cigarette, thereby improving heating efficiency. It can also monitor the operating status of the cigarette heating resonant cavity 300, promptly detect abnormalities, and avoid overheating or other potential safety risks. The voltage curve shaping and conversion unit 107 improves signal resolution, enabling the system to more accurately control the output of the radio frequency solid-state source 102 and optimize overall performance. The introduction of the coprocessor 103 enables the system to achieve intelligent control, dynamically adjusting operating parameters based on real-time feedback, improving the system's adaptability and reliability.

[0051] like Figure 3 As shown, in an optional embodiment, the power detection unit 106 further includes a second diode D2, the input terminal of which is connected to signal ground, and the output terminal of which is connected to the input terminal of the first diode D1.

[0052] In this embodiment, it should be noted that the second diode D2 provides additional protection, preventing reverse current flow and ensuring the safety of the first diode D1 and the stability of the circuit. By adding the second diode D2, the stability and reliability of the circuit are enhanced, thereby improving measurement accuracy. The shaped voltage signal is easier to process and analyze, providing more accurate data for subsequent signal processing and control.

[0053] like Figure 4 As shown, in an optional embodiment, the voltage curve shaping and conversion unit 107 further includes: a second operational amplifier U2, a third diode D3, an eighth resistor R8, and a ninth resistor R9, wherein the eighth resistor R8 is connected in series between the output terminal of the first diode D1 and the inverting input terminal of the second operational amplifier U2; the ninth resistor R9 is connected in series between the non-inverting input terminal of the second operational amplifier U2 and signal ground; the input terminal of the third diode D3 is connected to the inverting input terminal of the second operational amplifier U2, the output terminal of the third diode D3 is connected to the output terminal of the second operational amplifier U2, and the output terminal of the second operational amplifier U2 is connected to the non-inverting input terminal of the first operational amplifier U1.

[0054] In this circuit, it should be noted that the voltage curve shaping and conversion unit 107 is further extended to include a second operational amplifier U2, a third diode D3, an eighth resistor R8, and a ninth resistor R9. This design provides more complex signal processing capabilities, allowing for finer control and shaping of the voltage signal. The second operational amplifier U2 is used to further process and shape the voltage signal output from the first operational amplifier U1. Working together with the third diode D3, the eighth resistor R8, and the ninth resistor R9, it forms a more complex signal processing chain. The third diode D3 provides additional rectification or signal clamping functionality, which can be used to limit the polarity or amplitude of the voltage. Its input is connected to the inverting input of the second operational amplifier U2, and its output is connected to the output of the second operational amplifier U2. The eighth resistor R8 is used to set the gain or bias of the second operational amplifier U2. It is connected in series between the output of the first diode D1 and the inverting input of the second operational amplifier U2. The ninth resistor R9 is used to stabilize the input of the second operational amplifier U2 or provide bias. It is connected in series between the non-inverting input of the second operational amplifier U2 and signal ground.

[0055] Furthermore, the microwave solid-state source-based electronic cigarette also includes a system function module 200, which is connected to a coprocessor 103 and controls the operating state of the radio frequency solid-state source module 100 through the coprocessor 103. The system function module 200 includes a human-machine interface unit and a communication unit for user interaction and external communication.

[0056] In this embodiment, the microwave solid-state source-based electronic cigarette system is expanded to include a system function module 200. This module is connected to a coprocessor 103 and can control the operating state of the radio frequency solid-state source module 100 through the coprocessor 103. The system function module 200 includes a human-machine interface unit and a communication unit for user interaction and external communication. The human-machine interface unit in the system function module 200 provides an interactive interface between the user and the electronic cigarette system, including displaying information and receiving user input. It may include an LCD / LED display, buttons, a touchscreen, indicator lights, etc. It allows users to view the electronic cigarette's status information (such as battery level, heating status, temperature, etc.) and make settings or adjustments (such as heating power, operating mode, etc.). The communication unit enables data exchange and communication between the electronic cigarette system and other devices (such as smartphones, computers, etc.). It may include a Bluetooth module, a Wi-Fi module, a USB interface, etc. It supports remote control, data synchronization, firmware updates, and other functions, enabling users to monitor and configure the electronic cigarette's operating status through external devices. As a bridge between the system functional module 200 and the RF solid-state power source module 100, it receives user commands from the human-machine interface unit and external commands from the communication unit, controlling the working state of the RF solid-state power source module 100. Based on the received commands, it dynamically adjusts the electronic cigarette's operating parameters (such as heating power and working time) to achieve intelligent control.

[0057] The RF solid-state source module 100 receives control signals from the coprocessor 103 and executes corresponding operations (such as adjusting heating power, changing operating mode, etc.). This ensures the electronic cigarette functions properly according to the user's or external device's requirements, providing the necessary heating and atomization functions. It can also accurately determine the presence of the e-cigarette holder, check if the holder meets the conditions for continued use, and verify if the inserted holder is compatible with the entire smoking device.

[0058] The embodiments described above are merely examples of several implementations of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application.
