Detailed Implementation

[0035] To better understand the purpose, structure, and function of this utility model, the following detailed description of an electronic cigarette provided by this utility model is provided in conjunction with the accompanying drawings, so that those skilled in the art can better understand and implement this utility model. However, the embodiments described are not intended to limit this utility model.

[0036] Example 1

[0037] Please see Figures 1 to 10 As shown, an electronic cigarette includes a power supply box 100, a power core 200, a charging connector 300, and a discharging connector 400. The power core 200 is disposed inside the power supply box 100. The charging connector 300 and the discharging connector 400 are located at opposite ends of the power core 200. A tab 210 is provided at the end of the power core 200 near the charging connector 300. A charging contact 310 is provided at the end of the charging connector 300 near the tab 210. The charging contact 310 abuts against the tab 210, and the charging connector 300 is electrically connected to the power core 200. A flexible circuit board 500 is also provided between the charging connector 300 and the discharging connector 400. The discharging connector 400 is electrically connected to the charging connector 300 through the flexible circuit board 500. An NFC module 510 for data interaction with external devices is provided on the flexible circuit board 500. A display module 520 for displaying the e-liquid level and / or battery level is provided on one side of the NFC module 510. The display module 520 is electrically connected to the flexible circuit board 500, and a viewing hole 110 is provided on the side of the power box 100 opposite to the display module 520. NFC (Near Field Communication) technology is a short-range wireless communication technology with characteristics such as speed, convenience, and security.

[0038] The system includes a power supply box 100, a power core 200, a charging connector 300, a discharging connector 400, and a flexible circuit board 500. A display module 520 on the flexible circuit board 500 provides a more three-dimensional and intuitive display of the remaining e-liquid and power core 200 levels, allowing users to easily check the status at any time. It also reminds users to add e-liquid or charge the e-cigarette when the e-liquid or battery is low, preventing disruption to normal use due to insufficient e-liquid or battery. This effectively solves the problem of existing e-cigarettes lacking e-liquid level indicators, which can lead to users smoking without knowing the remaining e-liquid level and potentially causing unpleasant odors. Furthermore, the flexible circuit board 500 incorporates an NFC module 510, allowing users to read information stored in the e-cigarette via external devices, and the e-cigarette to access data set by the user on external devices, enabling real-time data transmission. This simple and convenient operation enhances the user experience. Additionally, the charging connector 300 and power core 200 achieve electrical conductivity without soldering, reducing the difficulty of assembly and maintenance.

[0039] Specifically, an NFC module 510 is installed on the flexible circuit board 500. The NFC module 510 includes an NFC signal receiving chip, allowing users to read information stored in the e-cigarette via external devices. The e-cigarette can also acquire data set by the user on external devices. Data transmission is achieved simply by placing the external device and the e-cigarette together, enabling real-time data transfer—convenient, easy to operate, and enhancing the user experience. The external device can be an NFC-enabled mobile phone, tablet, or similar device. For example, users can connect to a website or app via the NFC module 510 and adjust the output voltage of the power supply chip 200 to control the concentration of e-cigarette vapor, meeting different user needs and improving the user experience. Furthermore, by setting an electrode 210 at one end of the power core 200 near the charging connector 300, and setting a charging contact 310 at the charging connector 300 near the electrode 210, the charging contact 310 and the electrode 210 abut against each other, achieving electrical conductivity between the charging connector 300 and the power core 200 without soldering, thus reducing the difficulty of assembling and maintaining the e-cigarette. The discharge connector 400 is electrically connected to the charging connector 300 via a flexible circuit board 500, thereby achieving electrical conductivity between the discharge connector 400 and the power core 200. When the power core 200's power is insufficient, it can be connected to an external power source through the charging connector 300 to charge it. Moreover, by setting a display module 520, the remaining e-liquid and power core 200 levels are displayed more three-dimensionally and intuitively, allowing users to easily check at any time. It also reminds users to add e-liquid or charge the e-cigarette when e-liquid or power is low, preventing the e-cigarette from being affected by insufficient e-liquid or power. Meanwhile, by setting up the power supply box 100, not only are the internal electronic components such as the power supply core 200 effectively protected, but the disassembly, assembly, and portability of the electronic cigarette are also facilitated. Furthermore, by incorporating the flexible circuit board 500, the internal space of the power supply box 100 can be effectively reduced, resulting in simpler and more organized wiring for the electronic cigarette and easier assembly.

[0040] In a preferred embodiment, the display module 520 is an LED display screen, and the visible through hole 110 is a square visible through hole 110, which is arranged opposite to the LED display screen.

[0041] Specifically, by setting up an LED display screen, the levels of e-liquid and the power supply (over 200 units) are displayed more three-dimensionally and intuitively on the screen, allowing users to easily check at any time. It also reminds users to add e-liquid or charge the e-cigarette when the e-liquid or battery is low, preventing disruption to normal use due to insufficient e-liquid or battery power. Furthermore, the LED display screen is electrically connected to the flexible circuit board (500 units), eliminating the need for a separate LED display screen mounting bracket and significantly reducing production costs.

[0042] In a preferred embodiment: the charging connector 300 includes a charging plate 320 and a charging terminal 330, and charging contacts 310 are disposed on at least one surface of the charging plate 320; the charging plate 320 is detachably disposed within the power supply box 100, one end of the charging terminal 330 is electrically connected to the charging plate 320, and the other end extends out of the power supply box 100 in a direction away from the charging plate 320. The charging contacts 310 may be disposed on one or more surfaces of the charging plate 320 to increase the contact area between the charging contacts 310 and the tabs 210, thereby improving the conductivity between the charging plate 320 and the power core 200.

[0043] In a preferred embodiment: the tab 210 includes a connecting portion 211 and a conductive portion 212; the connecting portion 211 and the conductive portion 212 are integrally formed; the conductive portion 212 is hook-shaped, and the tail end of the conductive portion 212 abuts against and communicates with the charging contact 310.

[0044] Specifically, by setting the conductive part 212 in a hook shape and placing the charging contact 310 at the bend at the tail end of the conductive part 212, the contact area between the charging contact 310 and the conductive part 212 is increased, thereby improving the conductivity of the charging board 320 and the power core 200.

[0045] In a preferred embodiment, the discharge connector 400 includes a discharge plate 410 and a discharge terminal 420. The discharge plate 410 is located inside the power supply box 100 and is electrically connected to the charging board 320 via a flexible circuit board 500. One end of the discharge terminal 420 is electrically connected to the discharge plate 410, and the other end extends out of the power supply box 100 in a direction away from the discharge plate 410. The discharge plate 410 is a microphone board, and the flexible circuit board 500 enables the discharge plate 410 to be electrically connected to the charging board 320, thereby allowing the discharge plate 410 to be electrically connected to the power supply core 200.

[0046] In a preferred embodiment, a cigarette holder 600 is also provided outside the power supply box 100. The surface of the cigarette holder 600 is provided with a viewing element 610 corresponding to the viewing hole 110. One end of the cigarette holder 600 is also provided with a cigarette cartridge module 700 that abuts against the discharge terminal 420. The cigarette cartridge module 700 includes a mouthpiece 710, a smoke outlet channel 720, an oil storage chamber 730, and a ceramic heating element 740. The mouthpiece 710 is located at one end of the smoke outlet channel 720 and is connected to the smoke outlet of the smoke outlet channel 720. The smoke outlet channel 720 is located on one side of the oil storage chamber 730. The ceramic heating element 740 is located near the opening of the oil storage chamber 730 and is connected to the smoke inlet of the smoke outlet channel 720. The end face of the ceramic heating element 740 away from the oil storage chamber 730 abuts against the discharge terminal 420, so that the ceramic heating element 740 and the power supply core 200 are electrically connected to each other.

[0047] Because a vapor chamber 600 is also provided outside the power supply box 100, and a viewing element 610 corresponding to the viewing hole 110 is provided on the surface of the vapor chamber 600, and a cartridge module 700 that abuts against the discharge terminal 420 is provided at one end of the vapor chamber 600, the ceramic heating element 740 can achieve mutual electrical conduction with the power core 200 without the need for the pins to make contact with the discharge terminal 420 for electrical conduction. This not only simplifies and facilitates assembly but also reduces production costs. Specifically, the micropores on the ceramic heating element 740 absorb the e-liquid in the oil storage chamber 730. By abutting the discharge terminal 420 against the end face of the ceramic heating element 740 of the cartridge module 700, electrical conduction is achieved between the ceramic heating element 740 and the power core 200. Under the action of current, the ceramic heating element 740 is triggered to heat up, causing the e-liquid inside to atomize and produce smoke. In addition, by connecting the ceramic heating element 740 to the smoke inlet of the smoke outlet channel 720 and the mouthpiece 710 to the smoke outlet of the smoke outlet channel 720, smoke can enter the mouthpiece 710 along the smoke outlet channel 720.

[0048] In a preferred embodiment, a first sealing layer 750 is provided at one end of the mouthpiece 710 near the oil storage chamber 730. The first sealing layer 750 includes a sealing part 751 and a connecting part 752, which are integrally formed. The sealing part 751 is disposed on the oil storage chamber 730, and the connecting part 752 is disposed on the smoke outlet channel 720.

[0049] Specifically, by providing the sealing portion 751 of the first sealing layer 750 at the port of the oil storage chamber 730, the normal use of the electronic cigarette can be prevented from being affected by the e-liquid flowing out of the oil storage chamber 730. In addition, a smoke passage hole is provided on the connecting portion 752 of the first sealing layer 750, which communicates with the smoke outlet channel 720, so that the smoke can enter the mouthpiece 710 along the smoke outlet channel 720.

[0050] In a preferred embodiment, the sealing part 751 is further provided with a groove 753, and the mouthpiece 710 is provided with an oil injection hole 711 that communicates with the groove 753. The oil injection hole 711 is used to facilitate the e-liquid injector 800 to enter and pierce the groove 753 to inject oil into the oil storage chamber 730.

[0051] Because the mouthpiece 710 has an oil injection hole 711 that communicates with the groove 753, e-liquid is added to the oil reservoir 730 through the cooperation of the oil injection hole 711 and the groove 753. Specifically, the tip of the e-liquid injector 800 pierces the sealing part 751 through the oil injection hole 711 and enters the oil reservoir 730 to add e-liquid. It should be noted that the first sealing layer 750 is made of a soft material, but is not limited to silicone. The material has good resilience, thus ensuring that a certain degree of sealing is maintained after the e-liquid injector 800 is pierced and removed.

[0052] In a preferred embodiment, the ceramic heating element 740 includes a ceramic heating core 741 and a sealing ring 742, with the sealing ring 742 sleeved on the outer peripheral sidewall of the ceramic heating core 741.

[0053] Since a sealing ring 742 is fitted on the outer peripheral side wall of the ceramic heating core 741, the ceramic heating core 741 can be more securely installed at the opening at the bottom of the oil storage chamber 730, and oil leakage at the bottom of the oil storage chamber 730 can be effectively prevented.

[0054] In a preferred embodiment, the ceramic heating core 741 is arranged in a flat column shape. The end of the ceramic heating core 741 near the oil storage chamber 730 is provided with a receiving cavity 741A, which is connected to the oil storage chamber 730. The end of the ceramic heating core 741 away from the receiving cavity 741A is provided with a discharge contact 741B. The ceramic heating core 741 is electrically connected to the discharge terminal 420 through the discharge contact 741B.

[0055] Because the ceramic heating element 741 has a receiving cavity 741A at one end near the oil storage chamber 730, and the receiving cavity 741A is connected to the oil storage chamber 730, the e-liquid in the oil storage chamber 730 can enter the receiving cavity 741A and permeate into the interior of the ceramic heating element 741 through the micropores on the ceramic heating element 741, thus facilitating the penetration of the e-liquid. In addition, the discharge contact 741B is located at the end of the ceramic heating element 741 away from the receiving cavity 741A, and abuts against the discharge terminal 420 through the discharge contact 741B, making the ceramic heating element 741 electrically connected to the power supply core 200. Under the action of the current, the ceramic heating element 741 is triggered to heat up, causing the e-liquid inside the ceramic heating element 741 to atomize and produce smoke.

[0056] In a preferred embodiment, a second sealing layer 760 is provided at one end of the oil storage chamber 730 near the discharge terminal 420. The second sealing layer 760 has an electrode hole 761 and an airflow hole 762. The discharge terminal 420 is located inside the electrode hole 761. One end of the airflow hole 762 is connected to the smoke inlet of the smoke outlet channel 720, and the other end is connected to the air inlet 630 at the end of the cigarette rod 600 away from the cigarette cartridge module 700, so that the air inlet 630 is connected to the mouthpiece 710 to form an air intake path.

[0057] By providing a second sealing layer 760 at one end of the oil storage chamber 730 near the power module, and forming a cavity between the second sealing layer 760 and the ceramic heating core 741, the ceramic heating core 741 is connected to the smoke inlet of the smoke outlet channel 720, allowing the smoke generated by the atomization of e-liquid to enter the mouthpiece 710 along the smoke outlet channel 720. Furthermore, the second sealing layer 760 prevents the generated smoke from diffusing towards one end of the e-cigarette rod 600. Additionally, by providing an electrode hole 761, the discharge connector 400 can pass through the electrode hole 761 and the second sealing layer 760 to abut against the discharge contact 741B. Furthermore, a tail cap 620 is fitted onto the end of the cigarette holder 600 furthest from the cartridge module 700. The tail cap 620 has a hollow structure, with its hollow portion communicating with the charging terminal 330. An air inlet 630 is formed between the side wall of the tail cap 620 and the end of the cigarette holder 600, facilitating airflow into the cigarette holder 600. Multiple air inlets 630 can be provided. Additionally, an airflow hole 762 is provided in the second sealing layer 760, with both ends of the airflow hole 762 communicating with the smoke outlet channel 720 and the air inlet 630 respectively, thus forming an air intake path. That is, when the user inhales into the mouthpiece 710, airflow can enter the inside of the cigarette holder 600 through the air inlet 630, then enter the cavity through the airflow hole 762, and carry the smoke along the smoke outlet channel 720 into the mouthpiece 710, thereby achieving the purpose of smoking.
