Description

Technical Field

[0001] This utility model relates to the field of microwave technology, and in particular to an electronic cigarette radio frequency source device. Background Technology

[0002] With the rapid development of HNB (heated non-combustible) technology, electronic cigarette aerosol generators are gradually becoming an important alternative to traditional cigarettes. Their core objective is to heat the tobacco matrix (such as tobacco shreds) through precise temperature control technology, allowing it to release aerosols while preventing combustion, thereby reducing the generation of harmful substances and improving the user experience. In this field, microwave / radio frequency heating technology, due to its unique penetration and uniformity, has become a key solution for achieving efficient and controllable heating. Microwave heating is based on the principle of polar molecules generating heat through spin friction in a high-frequency electromagnetic field. It can penetrate the inner and outer layers of tobacco shreds, achieving uniform heating, effectively solving the temperature gradient problem existing in traditional heating methods, and significantly improving aerosol release efficiency and taste quality.

[0003] However, as the core energy source of microwave / RF heating technology, the radio frequency (RF) functional board generates a high-intensity electromagnetic field when emitting RF radiation.

[0047] Please refer to Figure 1 - Figure 6 One embodiment of this application provides an electronic cigarette radio frequency source device 100, the device 100 including: radio frequency function board 10, shielding isolation frame 20 and system function board 30.

[0048] The shielding isolation frame 20 is fixedly connected to the radio frequency functional board 10. The system functional board 30 is fixedly connected to the shielding isolation frame 20 and is located on the side of the shielding isolation frame 20 opposite to the radio frequency functional board 10. An accommodating space 40 is formed between the radio frequency functional board 10, the shielding isolation frame 20 and the system functional board 30. The shielding isolation frame 20 is integrally formed with a shielding partition group 21, and the shielding partition group 21 divides the accommodating space 40.

[0049] The RF function board 10, as the core RF energy output module, is mainly responsible for handling the RF energy source and resonant cavity status detection tasks. The RF function board 10 is the part of the electronic cigarette RF source device 100 directly related to RF energy, ensuring the functions of heating and energy transmission. It is also the basic module for the entire device 100 to achieve RF heating and control the resonant state. The shielding isolation frame 20 is fixedly connected to the RF function board 10 and integrates a shielding partition group 21. Its main function is to achieve electromagnetic shielding and isolation, preventing RF signal leakage or external electromagnetic interference. It also serves to separate the internal space, optimize the layout of each functional module, and ensure the purity of the RF signal and the EMI / EMC (electromagnetic interference / electromagnetic compatibility) performance of the electronic cigarette RF source device 100. The system function board 30 carries system-level functions such as control, processing, and management, including a microprocessor, memory, and power-on circuit. It works in conjunction with the RF function board 10. The system function board 30 is mainly responsible for processing user commands and controlling the coordinated operation of various components according to user requirements. Its placement helps reduce direct interference with the RF circuit and maintains stable internal signal transmission. The accommodating space 40 provides a closed space for each electronic component in the device 100. The shielding partition group 21 divides the internal space into multiple functional domains, which can effectively isolate the interference between radio frequency signals and other circuits or functional domains, and improve the overall system's working stability and anti-interference capability.

[0050] More preferably, the device 100 further includes a heat dissipation metal block 50 and an radio frequency output port 60.

[0051] The heat dissipation metal block 50 is fixedly connected to the radio frequency functional board 10 and is located on the side of the radio frequency functional board 10 opposite to the shielding isolation frame 20. The radio frequency output port 60 is fixedly connected to one side surface of the shielding isolation frame 20 and the same side surface of the heat dissipation metal block 50.

[0052] The heat dissipation metal block 50 is fixedly connected to the RF functional board 10, located on the side of the RF functional board 10 opposite to the shielding isolation frame 20. The heat dissipation metal block 50 is mainly used to dissipate the heat generated by the RF functional board 10, ensuring temperature stability during high-frequency operation, extending component lifespan, and preventing overheating failures. Positioning the heat dissipation metal block 50 on the side opposite to the shielding isolation frame 20 helps isolate heat from other circuit boards (such as the system functional board 30), reducing the impact of heat transfer on the performance of other modules. Simultaneously, its close integration with the RF functional board 10 makes full use of the limited space for heat dissipation design. The RF output port 60 serves as the connection point between the electronic cigarette RF source device 100 and the cigarette heating resonant cavity, responsible for transmitting RF energy. The two parts of the RF output port 60 are respectively located on the same side surface of the shielding isolation frame 20 and the heat dissipation metal block 50, helping to achieve efficient signal output while maintaining electromagnetic shielding effectiveness. This layout ensures both signal transmission stability and heat dissipation design, ensuring that heat does not affect the stable transmission of RF signals during device operation.

[0053] More preferably, when viewed along a direction perpendicular to the radio frequency functional board 10, the shielding partition group 21 includes: a first partition 21A, a second partition 21B, a third partition 21C, and a fourth partition 21D.

[0054] One end of the second partition 21B is fixedly connected to the first partition 21A. The third partition 21C is fixedly connected to the other end of the second partition 21B and is located on the side of the second partition 21B opposite to the first partition 21A. The fourth partition 21D is located on the side of the third partition 21C opposite to the second partition 21B.

[0055] The multi-partition design divides the internal space 40 of the electronic cigarette RF source device 100 into several independent areas, effectively isolating RF radiation from the RF functional board 10, preventing mutual interference between different functional areas of the RF functional board 10, and improving the overall electromagnetic compatibility (EMI / EMC) of the device 100. The connection method of fixing one end of the second partition 21B to the first partition 21A ensures the overall stability and structural consistency of the partition group, while providing an accurate positioning basis for subsequent partitioning, ensuring the accuracy and reliability of the internal space division. The third partition 21C is fixedly connected to the other end of the second partition 21B and is located on the side of the second partition 21B opposite to the first partition 21A, distinguishing the side of the shielding isolation frame 20 opposite to the first partition 21A. When viewed perpendicular to the RF functional board 10, the first partition 21A and the third partition 21C form a stepped partition. The arrangement of the fourth partition 21D on the side of the third partition 21C away from the second partition 21B further extends the partition structure, allowing the accommodating space 40 to be divided into multiple functional areas.

[0056] More preferably, viewed along a direction perpendicular to the RF functional board 10, the first partition 21A, the second partition 21B, the third partition 21C, and the fourth partition 21D divide the accommodating space 40 into a first domain 41, a second domain 42, a third domain 43, and a fourth domain 44. The first domain 41 is located on the side of the first partition 21A near the surface of the device 100 where the RF output port 60 is fixedly connected. The first domain 41 is the space formed by the first partition 21A, the second partition 21B, the third partition 21C, and the frame of the shielding isolation frame 20. The second domain 42 is another space formed by the first partition 21A, the second partition 21B, the third partition 21C, and the frame of the shielding isolation frame 20. The second domain 42 is located on the side of the second partition 21B opposite to the first domain 41, and on the side of the first partition 21A opposite to the first domain 41.

[0057] This partitioned structure places different functional modules (such as high-power radio frequency (RF) signals, power detection, low-power radio frequency (RF) signals, and DC power supplies) in their respective independent spaces, effectively isolating them from electromagnetic interference, improving the electromagnetic compatibility and operational stability of the entire system, and facilitating modular design and heat dissipation management. The first domain 41 is designed as the high-power RF signal area, responsible for outputting high-power RF signals. The RF output port 60 is located near the surface of the device 100, contributing to efficient signal transmission. Simultaneously, the frame structure and partitions together form a shielding layer, preventing high-power signals from interfering with other areas and avoiding the intrusion of external noise. The second domain 42 is designed as the power detection area, specifically for monitoring and detecting the power of RF signals. This spatial and structural isolation helps provide a relatively stable environment with less interference, ensuring the accuracy of the detection data and thus guaranteeing precise control of the RF signal output.

[0058] More preferably, viewed along a direction perpendicular to the RF functional board 10, the third domain 43 is located on the side of the fourth partition 21D closer to the third partition 21C, and the third domain 43 is the space formed by the third partition 21C, the fourth partition 21D, and the frame of the shielding isolation frame 20. The fourth domain 44 is located on the side of the fourth partition 21D away from the third partition 21C, and the fourth domain 44 is the space formed by the fourth partition 21D and the frame of the shielding isolation frame 20.

[0059] The design of the third domain 43 ensures a well-shielded space within it, preventing external interference. Domain 43, being a small-signal RF region, facilitates precise processing of low-power, sensitive RF signals and reduces electromagnetic interference from other areas (such as high-power or power supply sections). The fourth domain 44 is the DC power supply region. Its design ensures a stable power supply environment for the power supply section and prevents DC power supply noise from affecting the large and small signal RF regions and the power detection region.

[0060] More preferably, the radio frequency functional board 10 includes a first electronic component group 11, which is electrically connected to and fixedly connected to the surface of the radio frequency functional board 10, with the surface located on the side of the radio frequency functional board 10 opposite to the heat dissipation metal block 50. The first electronic component group 11 is disposed in the first domain 41, the second domain 42, the third domain 43, and the fourth domain 44.

[0061] The first electronic component group 11 is integrated on the radio frequency (RF) functional board 10 and works in conjunction with it via electrical connection. The first electronic component group 11 is fixed to the surface of the RF functional board 10, and this surface is positioned away from the heat sink 50. This arrangement allows each electronic module to be placed within the accommodating space 40. The partitions within the accommodating space 40 ensure the reliability and stability of each electronic module, preventing weakening of RF radiation due to mutual electromagnetic interference, and ultimately reducing the RF heating performance of the electronic cigarette RF source device 100. Choosing the side away from the heat sink 50 reduces the impact of heat on sensitive RF circuits (such as the RF solid-state source, circulator, coupler, and power detection module), thereby improving the overall system's stability and accuracy. The first electronic component group 11 is configured within pre-defined first domain 41, second domain 42, third domain 43, and fourth domain 44. This partitioned layout helps to physically isolate high-power, large-signal components from low-power, small-signal, and power supply components, effectively reducing electromagnetic interference between different functional modules. In addition, the operating environment of each corresponding module within each domain can be optimized specifically (e.g., RF high-signal area, power detection area, RF low-signal area, DC power supply area) to ensure the coordinated and efficient operation of the overall system. In the first electronic component group 11, the DC boost circuit is used to boost the input DC voltage to a higher voltage level suitable for the operation of the RF module. It provides the necessary voltage drive for high-power RF modules such as the RF solid-state source, ensuring that the device can output stable and sufficient RF energy. The RF solid-state source is used to generate RF signals and is the core signal source of the entire RF heating or transmission process. It ensures that the electronic cigarette RF source device 100 has a stable and sufficient RF energy output and is a key component for achieving uniform heating and aerosol generation. The coprocessor is used to coordinate and manage the generation, regulation, and monitoring of RF signals. It ensures signal synchronization and data processing between modules, improving system response speed and operational accuracy. The circulator controls the direction of signal transmission, preventing reflected signals from returning to the source. It protects the RF solid-state source from interference by reflected signals while improving the efficiency and stability of RF transmission. The coupler extracts a small portion of the radio frequency (RF) signal for subsequent monitoring or measurement, providing real-time signal feedback to the power detection module. This facilitates precise monitoring and adjustment of the RF output power. The power detection module detects and monitors the RF signal power, providing real-time feedback on the RF output status to ensure the equipment operates at its optimal state during operation. It also serves as a crucial basis for system self-testing and safety protection.

[0062] More preferably, the radio frequency functional board 10 further includes a battery 12.

[0063] The battery 12 is fixedly connected to the radio frequency functional board 10 and is located on the side of the radio frequency functional board 10 opposite to the first electronic component group 11. The battery 12 is electrically connected to the radio frequency functional board 10 and supplies power to the radio frequency functional board 10. When the heat dissipation metal block 50 is fixedly connected to the radio frequency functional board 10, the battery 12 is embedded in the heat dissipation metal block 50.

[0064] In this design, the battery 12 is fixedly connected to the RF functional board 10 and positioned on the side opposite to the first electronic component group 11 (including the RF solid-state source, circulator, coupler, etc.). This arrangement makes full use of the limited space and prevents the battery 12 from occupying or interfering with the layout of the core RF circuitry, thus achieving a modular and compact design. Since the first electronic component group 11 processes high-precision RF signals, its operating state is sensitive to electromagnetic interference and temperature fluctuations. Placing the battery 12 on the opposite side of these electronic components reduces the impact of electromagnetic noise or heat generated by the battery 12 on sensitive circuitry, ensuring the signal stability of the overall system. When the heat sink 50 is fixedly connected to the RF functional board 10, the battery 12 is embedded within it. This design helps utilize the thermal conductivity of the heat sink 50 to dissipate heat from the battery 12 and its surrounding area, preventing localized overheating. While ensuring a stable temperature for the RF functional board 10 and its core circuitry, this design also provides a relatively balanced temperature control environment for the battery 12, thereby extending its lifespan and ensuring power supply stability. Meanwhile, the arrangement of the battery 12 embedded in the heat dissipation metal block 50 also effectively utilizes the space of the device, thereby compressing the overall volume of the electronic cigarette radio frequency source device 100.

[0065] More preferably, the system function board 30 includes a second electronic component group 31, which is electrically connected to the system function board 30 and fixedly connected to the surface of the system function board 30, with the surface located on the side of the system function board 30 away from the shielding isolation frame 20.

[0066] The second electronic component group 31 is electrically connected to the system function board 30 and is fixedly mounted on the surface of the system function board 30. The layout of this surface, located away from the shielding frame 20, helps to form an independent and relatively clean control area, avoiding unnecessary electromagnetic interference due to proximity to the radio frequency components. Simultaneously, the fixed mounting ensures the mechanical stability between modules and the reliability of electrical connections, contributing to the long-term stable operation of the electronic cigarette radio frequency source system. The microprocessor, as the core control unit of the device, is responsible for executing programs and coordinating the work of each module. The memory stores program code, data, and device operating status, ensuring the system can perform logical judgments and data processing. The power-on circuit ensures the device can start smoothly and enter the working state. The charging circuit manages the charging process of battery 12, ensuring a safe and stable power supply to maintain the continuous operation of the entire system. LED indicators visually display the device's operating status, fault alarms, or power information. Buttons provide a direct operating interface for users to select device modes or set parameters. The communication interface supports data exchange with external devices, facilitating remote monitoring or data transmission, improving user experience and device intelligence. The motor drive module controls the operation of the internal motor, which may be related to smoke generation, fan cooling, or other mechanical actions, ensuring that the mechanical components and electronic control system work together. The microphone airflow detection module monitors changes in airflow during inhalation, triggering corresponding heating or feedback controls to optimize the smoking experience. The temperature detection module monitors the internal temperature of the device in real time, ensuring the operating environment remains within a safe range and preventing malfunctions or safety issues caused by overheating.

[0067] More preferably, the system function board 30 also includes a power interface 32.

[0068] The power interface 32 is fixedly connected to the system function board 30 and is located on the side of the system function board 30 away from the second electronic component group 31. The power interface 32 is electrically connected to the system function board 30 and is connected to an external power source to supply power to the system function board 30.

[0069] The power interface 32 is fixedly connected to the system function board 30 and positioned on the side away from the second electronic component group 31, effectively isolating the electromagnetic noise or interference generated by internal radio frequency radiation on the external power supply. The location of the power interface 32 on the side of the system function board 30 away from the second electronic component group 31 achieves physical isolation, ensuring that different functional modules (such as control processing and power management) have their own independent working areas on the same board. This facilitates overall circuit layout and heat dissipation management, improving system reliability. Through fixed and electrical connections, the power interface 32 is tightly integrated with the system function board 30, ensuring a stable connection of the external power supply to the system. This not only enhances the reliability of the power supply but also facilitates maintenance and replacement during actual use, extending the product's lifespan and safety.

[0070] More preferably, the radio frequency function board 10 is electrically connected to the system function board 30.

[0071] The electrical connection ensures that the data from the generation, regulation, and monitoring of radio frequency signals can be transmitted to the system function board 30 in real time. The microprocessor and other control circuits within the system function board 30 process and provide feedback, thereby enabling the radio frequency module to work collaboratively with the overall system. Through the electrical connection, the system function board 30 can set parameters, detect status, and provide fault protection for the radio frequency function board 10, thus achieving intelligent management and optimized adjustment of the entire device, ensuring that the entire device 100 remains in optimal condition during operation. The electrical connection method facilitates modular and integrated layout in the design, reducing the risk of interference between modules due to excessively long signal transmission paths, making the system structure more compact, the wiring simpler, and improving overall stability and reliability.

[0072] Therefore, by dividing the accommodating space 40 with the shielding partition group 21, the accommodating space 40 within the device 100 is divided into multiple regions, so that the electromagnetic interference between the regions within the accommodating space 40 can be effectively avoided. Furthermore, the design of the radio frequency functional board 10 being located on the side of the shielding isolation frame 20 away from the system functional board 30, and the accommodating space 40 being formed between the radio frequency functional board 10, the shielding isolation frame 20, and the system functional board 30, thereby enclosing the radio frequency radiation within the accommodating space 40, improves the electromagnetic compatibility between the circuits on the radio frequency functional board 10 and the circuits on the system functional board 30.

[0073] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this 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 protection scope of this application.
