Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, specifically to a cylindrical electronic cigarette that is easy to replace cartridges. Background Technology

[0002] Electronic cigarettes are electronic products that mimic traditional cigarettes. Based on their lifespan, electronic cigarettes can be broadly categorized into disposable and reusable types; among reusable electronic cigarettes, the cartridge-based type is the most common. A cartridge-based electronic cigarette mainly consists of a cartridge and a device. When the e-liquid in the cartridge is depleted, the cartridge can be replaced to continue using the electronic cigarette.

[0003] In the process of replacing cartridges in refillable e-cigarettes, the electrodes inside the cartridge need to be aligned with the electrodes on the device to ensure electrical conductivity between them. For rectangular or other irregularly shaped e-cigarettes, this alignment is often achieved naturally by observing the shape of the cartridge and device. However, for cylindrical e-cigarettes, it is difficult to align the cartridge and device by external observation alone. Current methods typically involve adding ribs or protrusions to the cartridge and / or device to ensure proper alignment during replacement.

[0004] It is evident that the existing method of assembling cylindrical e-cigarette cartridges and cylindrical e-cigarette rods requires alignment or rotational alignment, which reduces the convenience for e-cigarette users, affects the assembly efficiency of cartridges and rods, and diminishes the user experience.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1-5As shown, a cylindrical electronic cigarette with easy cartridge replacement includes a cartridge 1 and a cigarette rod 2. The cartridge 1 and the cigarette rod 2 are detachably connected. The cartridge replacement can be achieved by pulling the cartridge 1 out of the cigarette rod 2 and then inserting a new cartridge 1 into the cigarette rod 2.

[0024] The cigarette device 2 includes a cylindrical cigarette device shell 21. Inside the cigarette device shell 21, there is a battery 22 and an elastic pin. The elastic pin is electrically connected to the battery 22. When the cigarette cartridge 1 is inserted and fixed to the cigarette device 2, the elastic pin will be electrically connected to the cigarette cartridge 1, so that the battery 22 can supply power to the cigarette cartridge 1.

[0025] The cartridge 1 includes a cylindrical cartridge shell 11, one end of which can be inserted into the casing 21 of the e-cigarette. An atomizing component is housed inside the cartridge shell 11 for heating and atomizing e-liquid. An annular electrode is located at the end of the cartridge shell 11 near the e-cigarette 2, and this annular electrode is aligned with a flexible pin. The annular electrode connects to the flexible pin, thus electrically connecting the cartridge 1 and the e-cigarette 2. The annular electrode is electrically connected to the atomizing component, and through this connection, the battery 22 inside the e-cigarette 2 can power the atomizing component, enabling the cartridge 1 to heat and atomize the e-liquid during inhalation.

[0026] This easily replaceable cylindrical electronic cigarette features a ring electrode inside the cartridge 1. This allows the elastic pin to engage with the corresponding ring electrode regardless of the angle at which the cartridge 1 and the device 2 are connected, eliminating the need for manual alignment. This ensures that the cartridge 1 and device 2 remain connected even when rotated 360°, improving the portability of cartridge replacement and enhancing user experience.

[0027] In this embodiment, the elastic pin includes a first elastic pin 23 and a second elastic pin 24, which are electrically connected to the battery 22. The annular electrode includes a first annular electrode 12 and a second annular electrode 13, which is disposed inside the annulus of the first annular electrode 12, and the centers of the first annular electrode 12 and the second annular electrode 13 coincide. The first annular electrode 12 and the second annular electrode 13 are electrically connected to the atomizing component. The first elastic pin 23 can connect to the first annular electrode 12, and the second elastic pin 24 can connect to the second annular electrode 13. When installing the cartridge 1, after the cartridge shell 11 is inserted into the cigarette holder shell 21, the first annular electrode 12 connects with the first elastic pin 23, thereby pressing the first elastic pin 23 and making it electrically connected to the first annular electrode 12. Simultaneously, the second annular electrode 13 connects with the second elastic pin 24 and presses the second elastic pin 24, making it electrically connected to the second annular electrode 13. During use, the cartridge 1 can be freely rotated, and the first elastic pin 23 slides on the first annular electrode 12, always electrically connected to it; similarly, the second elastic pin 24 slides on the second annular electrode 13, always electrically connected to it.

[0028] To facilitate the installation of the elastic pins, a first mounting bracket 25 is fixedly installed inside the cigarette holder 21. The first mounting bracket 25 is fixedly connected to the inner side wall of the cigarette holder 21, and the first elastic pin 23 and the second elastic pin 24 are respectively fixedly inserted into the first mounting bracket 25. The first mounting bracket 25 enables the first elastic pin 23 and the second elastic pin 24 to be installed and fixed inside the cigarette holder 21, thereby improving the stability of the structure.

[0029] A second mounting bracket 14 is provided inside the cartridge shell 11 near the end of the tobacco rod 2. The second mounting bracket 14 is inserted and fixed to one end of the cartridge shell 11. A limiting step 141 is provided on the outer wall of the second mounting bracket 14 to limit the position of the cartridge 1 inserted into the tobacco rod 2. During the installation of the cartridge 1, the second mounting bracket 14 is inserted into the tobacco rod shell 21 until one end of the tobacco rod shell 21 abuts against the limiting step 141, indicating that the cartridge 1 and the tobacco rod 2 are installed in place. The cooperation between the tobacco rod shell 21 and the limiting step 141 ensures that the cartridge 1 and the tobacco rod 2 are firmly inserted, improves the stability of the structure, and facilitates the user to replace the cartridge 1.

[0030] To facilitate the fixing of the ring-shaped electrode 15, a fixing ring 15 is fitted onto the outer side wall of the second mounting bracket 14, and a limiting boss 151 is provided on the inner side wall of the fixing ring 15. During assembly, the ring electrode is first placed on the limiting boss 151, and then the fixing ring 15 is pressed into the second mounting bracket 14 as a whole, so that the fixing ring 15 and the second mounting bracket 14 are inserted and fixed, until the other side of the ring electrode abuts against the end of the second mounting bracket 14 near the cartridge 1. By fixing the ring electrode with the fixing ring 15 and the second mounting bracket 14, the ring electrode can be fixed in place, which can prevent the ring electrode from loosening and improve the stability of the structure.

[0031] The atomizing assembly includes an e-liquid reservoir 16 and a heating element 17. The e-liquid reservoir 16 is positioned and abuts against the inner wall of the cartridge shell 11. The heating element 17 is fixedly connected to the e-liquid reservoir 16 and electrically connected to a ring electrode. The e-liquid reservoir 16 is used to store e-liquid, and the heating element 17 is used to heat and atomize the e-liquid into an aerosol when energized. A mouthpiece 18 is provided at the end of the cartridge shell 11 away from the e-cigarette rod 2. The mouthpiece 18 is connected to the heating element 17 and is used by the user to inhale the e-cigarette.

[0032] Working principle:

[0033] When a user inhales the e-cigarette, they inhale through the mouthpiece 18, triggering a start signal. The battery 22 then supplies power to the heating element 17 through the cooperation of the elastic pin and the ring electrode. E-liquid flows from the oil reservoir 16 onto the heating element 17, which heats and atomizes the e-liquid into an aerosol. The atomized aerosol is then inhaled by the user through the mouthpiece 18, completing the e-cigarette inhalation process.

[0034] When it is necessary to replace the cartridge 1, the user can hold the cartridge shell 11 and pull the cartridge 1 out of the device 2. Then, the new cartridge 1 is reinserted into the device shell 21 until one end of the device shell 21 abuts against the limiting step 141. During the insertion of the cartridge 1, the first annular electrode 12 will connect with the first elastic pin 23, and the second annular electrode 13 will connect with the second elastic pin 24, thereby making the cartridge 1 and the device 2 electrically connected. During use, the cartridge 1 or the device 2 can rotate freely. The first elastic pin 23 will slide on the first annular electrode 12 and will always be electrically connected to the first annular electrode 12; at the same time, the second elastic pin 24 will slide on the second annular electrode 13 and will always be electrically connected to the second annular electrode 13.

[0035] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
