[0002] Currently, the e-cigarette industry generally uses a three-pin or four-pin solution to achieve communication between the cigarette rod and the cigarette cartridge.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] The terms "first," "second," and so on, in the specification and claims of this utility model and the accompanying drawings are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0049] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0050] The utility model provides a cigarette holder, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the frame of the cigarette rod in the second embodiment. The cigarette rod in this embodiment includes:

[0051] The power supply module 10 is used for supplying power.

[0052] Specifically, the power supply module 10 can be understood as the "battery" or "power management unit" of the electronic cigarette rod, which provides stable current and voltage to support the operation of other modules inside the cigarette rod.

[0053] The main control module 20 is connected to the power supply module 10 and is used to output communication control signals and / or heating control signals.

[0054] Specifically, when communication with the cigarette cartridge is required, the main control module 20 can generate and output communication control signals, which may include start, stop, data transmission, etc. When heating the cigarette cartridge is required, the main control module 20 will also output a corresponding heating control signal, instructing the cigarette rod to transmit power to the heating element of the cigarette cartridge.

[0055] The communication transceiver module 30 is connected to the main control module 20 and is used to generate a communication output signal in response to a communication control signal.

[0056] Specifically, the communication transceiver module 30 generates a carrier signal as a communication output signal in response to the communication control signal of the main control module 20. The carrier signal carries the communication information to be transmitted, such as data or instructions, through modulation.

[0057] The two ejector pins 40 are connected to the communication transceiver module 30 and the cigarette cartridge, and are used to send the communication output signal to the cigarette cartridge, and send the communication receiving signal fed back by the cigarette cartridge to the communication transceiver module 30.

[0058] Specifically, the ejector pins are the physical connection points between the cigarette holder and the cigarette cartridge. The two ejector pins 40 function as bidirectional signal transmission. On the one hand, they transmit the communication output signals generated by the communication transceiver module 30 to the cigarette cartridge, and on the other hand, they transmit the feedback signals generated by the cigarette cartridge back to the communication transceiver module 30. In this way, the ejector pins ensure effective communication between the cigarette holder and the cigarette cartridge.

[0059] The output control module 50 is connected to the main control module 20 and the power supply module 10 and is used to turn on the power supply in response to the heating control signal.

[0060] Specifically, in an actual circuit design, the output control module 50 may include a PMOS transistor as a switching element. The PMOS transistor can turn the power supply on or off under the control of the heating control signal. Specifically, when the gate voltage of the PMOS transistor drops sufficiently low, it conducts current, thereby transmitting power from the power supply module 10 to the component to be heated.

[0061] The isolation module 60 is connected to the output control module 50 and the two ejector pins 40 , and is used to supply power to the two ejector pins 40 and isolate the communication receiving signal.

[0062] Specifically, the isolation module 60 is connected to the output control module 50 and is responsible for receiving power from the module and transmitting it to the two ejector pins 40. To prevent interference with received communication signals, a circuit similar to a band-stop filter can be added to the isolation module 60. In this design, the isolation module 60 can be used to prevent high-frequency communication signals from flowing back into the power supply circuit or other circuit components, preventing other functional modules of the cigarette holder from being affected.

[0063] The two ejector pins 40 are also used to supply power and heat the cigarette cartridge.

[0064] That is to say, in addition to the communication function, the two ejector pins 40 can also be responsible for transmitting the power provided by the power supply module 10 to the cigarette cartridge, so as to heat the heating element in the cigarette cartridge to generate steam.

[0065] The cigarette holder in the above embodiment simplifies the structure of the electronic cigarette by integrating the power supply and communication functions into two ejector pins. These two ejector pins are not only used to transmit communication signals, but also to power and heat the cigarette cartridge. By reducing the number of ejector pins, the design complexity of the cigarette holder and cigarette cartridge is significantly reduced, thereby reducing production costs. In addition, reducing the number of ejector pins also reduces the wear of the ejector pins and contacts during the plugging and unplugging process, reducing the risk of failure caused by poor contact. Finally, reducing the number of ejector pins helps to improve the sealing of the cigarette cartridge, reduce the possibility of oil leakage, and thus improve the user experience. This design effectively solves the problems of increased costs, wear risks and sealing brought about by complex designs.

[0066] In a specific embodiment, Figure 2 As shown, the communication transceiver module includes a communication transceiver chip, a first resistor R45, a second resistor R43, a third resistor R57, a first capacitor C53, a second capacitor C21, a third capacitor C22, a fourth capacitor C39, a fifth capacitor C19, a sixth capacitor C37 and a first inductor L1.

[0067] The first power supply pin 2 and the second power supply pin 3 of the communication transceiver chip are connected to the power supply module and grounded through the first capacitor C53 . The third power supply pin 6 of the communication transceiver chip is grounded.

[0068] The control signal pins 13 and 16 of the communication transceiver chip are connected to the I2C SDA and I2C SCL communication interfaces of the main control module. The I2C interface is a common serial communication protocol. The SDA (data line) is used to transmit data, and the SCL (clock line) is used to synchronize data transmission. In this design, the main control module sends and receives control signals through the I2C interface, thereby managing the operation of the communication transceiver chip.

[0069] The first address setting pin 1 of the communication transceiver chip is connected to the power supply module through the first resistor R45. The second address setting pin 14 and the third address setting pin 15 of the communication transceiver chip are grounded. By setting the high and low levels of pins 1, 14, and 15 of the communication transceiver chip, multiple different I2C addresses can be generated.

[0070] The first end of the third capacitor C22 is connected to the first end of the second capacitor C21, the second end of the third capacitor C22 is grounded, the first end of the fourth capacitor C39 is connected to the second end of the second capacitor C21, the second end of the fourth capacitor C39 is grounded, and the communication output pin 7 of the communication transceiver chip is connected to the first end of the second capacitor C21 through the first inductor L1, the second end of the second capacitor C21 is connected to the positive pin of the two pins FUS, and the negative pin of the two pins FUS is grounded. Among them, this circuit design mainly forms an LC filtering network through the combination of the first inductor L1 and capacitors C21, C22, and C39, which is used to optimize the quality of the output signal of the communication transceiver chip. By filtering out noise and stabilizing the signal, the purity and stability of the signal when it is transmitted to the cigarette cartridge are ensured.

[0071] The communication receiving pin 9 of the communication transceiver chip is connected to the second end of the second capacitor C21 through the fifth capacitor C19 and the second resistor R43 connected in series. The voltage pin 8 of the communication transceiver chip is grounded through the sixth capacitor C37, and the third resistor R57 is connected to the communication receiving pin 9 and the voltage pin 8 of the communication transceiver chip. Among them, the fifth capacitor C19 isolates the DC and filters the signal, the second resistor R43 limits the current flowing into the communication receiving pin, and the third resistor R57 plays a key role in voltage and signal regulation. The sixth capacitor C37 is responsible for smoothing the voltage and ensuring the stability of the chip power supply. These measures together ensure the accurate reception of communication signals and the stable operation of the chip.

[0072] Furthermore, the communication transceiver module also includes a fourth resistor R66 and a seventh capacitor C55. The reset pin 4 of the communication transceiver chip is grounded via the seventh capacitor C55, connected to the power supply module via the fourth resistor R66, and connected to the reset interface CLK IN of the main control module. When the reset pin 4 is pulled low, the communication transceiver chip enters standby mode. This design allows the system to be reset during startup or under abnormal conditions, ensuring that the chip can return to normal operation. This configuration helps enhance system stability and reliability.

[0073] Furthermore, the communication transceiver module also includes an eighth capacitor C52. The clock signal input pin 10 of the communication transceiver chip is grounded via the eighth capacitor C52 and connected to the clock interface NRST of the main control module. This allows the chip to receive the clock signal from the main control module, ensuring synchronous operation. Furthermore, the clock signal input pin can also receive an external crystal oscillator to provide the necessary clock frequency.

[0074] In a specific embodiment, Figure 2As shown, the isolation module includes a second inductor L4 and a ninth capacitor C56. The ninth capacitor C56 is connected in parallel to both ends of the second inductor L4. The first end of the second inductor L4 is connected to the first output terminal VOUT H1 of the output control module. The second end of the second inductor L4 is connected to the second output terminal VOUT H2 of the output control module and is connected to the positive pin of the two FUS pins. The negative pin of the two FUS pins is grounded.

[0075] Specifically, the second inductor L4 and the ninth capacitor C56 together form a band-stop filter circuit, which uses the characteristics of inductance and capacitance to generate a frequency response curve. This curve is attenuated within a specific frequency range. When the frequency of the external signal is the same as the resonant frequency of the band-stop filter circuit, a resonant loop will be formed between the inductor and the capacitor, causing the external signal energy to be dissipated, thereby isolating the high-frequency signal interference. At the same time, the output control module outputs a low-frequency signal. Due to the low impedance characteristics of the second inductor L4 for DC signals, the low-frequency signal (including DC current) passes through L4 almost unaffected, directly from the inductor output to the top pin, and then transmitted to the cigarette cartridge. The DC resistance (DCR) of the second inductor L4 is small, so the current loss in the output circuit is also very small.

[0076] In a specific embodiment, Figure 3 As shown, the cigarette holder also includes a storage module 70, connected to the main control module 20, for storing images and parameters of the cigarette holder and cigarette cartridge. Images can include brand logos, instructions, or personalized user interface graphics. Parameters can include usage history, cigarette cartridge identification information, temperature settings, and more. These parameters can be accessed by the main control module to ensure proper operation of the device under different operating conditions.

[0077] In a specific embodiment, Figure 3 As shown, the cigarette holder also includes a display module 80, which is connected to the main control module 20 and is used to display image materials and parameters. Among them, this display module is a liquid crystal display (LCD), which allows users to directly see the device status and operation prompts on the screen, reducing misoperation and improving the convenience of device use.

[0078] The utility model also provides a cigarette cartridge, such as Figure 4 As shown, Figure 4 Schematic diagram of the framework of a cigarette cartridge in one embodiment. The cigarette cartridge in this embodiment includes: two ejector pin contacts 100, a memory chip 200, a heating wire 300 and cigarette oil 400.

[0079] The two ejector pin contacts 100 are connected to the two ejector pins of the cigarette rod and are used to receive the communication output signals sent by the two ejector pins and / or the power provided.

[0080] Memory chip 200, connected to two pin contacts 100, is used to transmit a received communication signal in response to an output communication signal. Memory chip 200 uses load modulation technology to transmit and receive data, eliminating the need to generate its own RF signal. This technology reduces chip complexity and power consumption, making it suitable for use in miniaturized devices.

[0081] The two ejector pin contacts 100 are also used to feed back the communication receiving signal to the two ejector pins of the cigarette rod.

[0082] The heating wire 300 is connected to the two ejector contacts 100 and contacts the e-liquid 400, and is used to heat the e-liquid 400 after receiving power.

[0083] The cigarette cartridge in the above embodiment integrates the communication and power supply functions into two ejector pin contacts, making the connection between the cigarette cartridge and the cigarette rod more concise and reducing the number of required contact points. This not only reduces the design complexity of the cigarette cartridge and the cigarette rod, but also effectively reduces manufacturing costs. At the same time, reducing the number of ejector pin contacts helps reduce wear and the risk of poor contact during the plugging and unplugging process, thereby reducing the product failure rate and improving product durability. At the same time, fewer ejector pin contacts also mean that the sealing of the cigarette cartridge can be better guaranteed, reducing the risk of oil leakage and improving the user experience.

[0084] The utility model also provides an electronic cigarette, such as Figure 5 As shown, the electronic cigarette includes the above-mentioned cigarette rod and the above-mentioned cigarette cartridge.

[0085] It should be noted that the above-mentioned cigarette rod, cigarette cartridge and electronic cigarette belong to a general utility model concept, and the contents of the cigarette rod, cigarette cartridge and electronic cigarette embodiments are applicable to each other.

[0086] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
