Description

具有管状雾化芯的电子烟Electronic cigarette with tubular atomizing core 技术领域Technical field
本发明涉及电子烟的技术领域，更具体的说，本发明涉及一种具有管状雾化芯的电子烟。The present invention relates to the technical field of electronic cigarettes, and more specifically, the present invention relates to an electronic cigarette with a tubular atomizing core.
背景技术Background technique
电子烟一般包括电池组件和雾化器，电池组件内具有给雾化器供应电源的电池，雾化器内设有雾化芯，雾化芯在通电时可将电子烟烟液加热蒸发产生气雾，供用户吸食。现有电子烟的雾化芯，主要包括有导液棉绳缠绕发热丝的结构，以及多孔陶瓷加发热电阻的结构。E-cigarettes generally include a battery assembly and an atomizer. The battery assembly contains a battery that supplies power to the atomizer. The atomizer is equipped with an atomizing core. When the atomizing core is powered on, it can heat and evaporate the e-cigarette liquid to produce gas. Mist for users to smoke. The atomizing core of existing electronic cigarettes mainly includes a structure with a liquid-conducting cotton rope wrapped around a heating wire, and a structure with porous ceramics and a heating resistor.
其中，现有电子烟的导液棉绳缠绕发热丝的结构，由于其导液棉绳可传导雾化液的导通横截面的面积小，工作时雾化量就较小，且在高温工作时因雾化座与导液棉绳密封不良就容易漏液。另外，现有电子烟的多孔陶瓷加发热电阻的结构，由于其多孔陶瓷内存在许多无序的微孔，在长时间工作时，电子烟烟液中含有的大分子和微颗粒、糖分等容易聚集、堵塞在多孔陶瓷的微孔内，且在高温下容易产生烧焦的焦味，导致用户吸烟时烟雾量降低、吸烟的口感前后不一致，口味不纯正甚至吸出焦味。Among them, the existing structure of the liquid-conducting cotton rope of the existing electronic cigarette is wrapped around the heating wire. Since the conductive cross-sectional area of the liquid-conducting cotton rope can conduct the atomized liquid is small, the amount of atomization is small during operation, and it operates at high temperatures. When the atomizer seat and the liquid-conducting cotton rope are poorly sealed, liquid leakage is easy to occur. In addition, the structure of the existing porous ceramics and heating resistors of e-cigarettes has many disordered micropores in the porous ceramics. When working for a long time, macromolecules, microparticles, sugars, etc. contained in the e-cigarette liquid are easily It accumulates and blocks in the micropores of porous ceramics, and easily produces a burnt smell at high temperatures, resulting in reduced smoke volume, inconsistent smoking taste, impure taste and even burnt smell when users smoke.

It can firmly support and attach the liquid-conducting cotton 62 outward to prevent the liquid-conducting cotton from deforming, loosening and causing liquid leakage. In this embodiment, the heating piece 63 is composed of a mesh having a plurality of through holes 632 . The through holes 632 of the mesh facilitate the aerosol generated by the evaporation of the smoke liquid to be emitted into the tube holes of the heating piece 63 .

When the interface is connected, it plays a sealing role to prevent the leakage of smoke liquid.
本发明实施例的导液棉62采用有机棉制成，并制成具有一定粘合力、不易分散的片状，即导液棉62由片状体构成。图9中所示的导液棉2系展开后的形状。本发明的导液棉，是指可传导烟液的棉质材料或棉状物质，并不局限于棉本身。在其它实施例中，导液棉2的构成材料还可以是陶瓷纤维棉、玻璃纤维棉、PP纤维、尼龙纤维、无纺布、PET纤维中的一种或几种混合构成，这些材料均为软质棉状材料。由于导液棉采用的上述原材料成本低、不需要烧结、工艺简单及结构简单，容易组装到雾化芯，可以极大地降低成本、提高生产效率。另导液棉的组成材料成分简单，相比一般的多孔陶瓷材料，不含有重金属的成分，故软质雾化芯在高温工作的条件下，没有重金属析出的风险。The liquid-conducting cotton 62 in the embodiment of the present invention is made of organic cotton, and is made into a sheet shape that has a certain adhesive force and is not easily dispersed. That is, the liquid-conducting cotton 62 is composed of a sheet-shaped body. The liquid-conducting cotton 2 shown in Figure 9 is in its unfolded shape. The liquid-conducting cotton of the present invention refers to a cotton material or cotton-like substance that can conduct smoke liquid, and is not limited to cotton itself. In other embodiments, the liquid-conducting cotton 2 may also be made of one or a combination of ceramic fiber cotton, glass fiber cotton, PP fiber, nylon fiber, non-woven fabric, and PET fiber. These materials are all Soft cotton-like material. Since the above-mentioned raw materials used in the liquid-conducting cotton are low in cost, do not require sintering, have simple processes and simple structures, they are easy to assemble into the atomizing core, which can greatly reduce costs and improve production efficiency. In addition, the liquid-conducting cotton is made of simple materials. Compared with ordinary porous ceramic materials, it does not contain heavy metal components. Therefore, the soft atomizer core has no risk of heavy metal precipitation under high-temperature working conditions.
如图11所示，在其它实施例中，发热片63与导液棉62之间还设有渗透管65，渗透管65上设有用于渗透烟液的渗透孔（图中未示）。渗透管65可起到向外支撑导液棉62、防止导液棉62在长时间高温工作下发生变形、向内凹陷的作用，同时还可通过渗透孔将导液棉2存储的烟液缓释到发热片63上，工作时使烟液的蒸发量与渗透量达到一种平衡，没有雾化时通过渗透孔的烟液形成表面张力达到另一种平衡，防止烟液泄漏。渗透管65可以做得很薄，渗透管65可以由耐高温、不导电的材料如塑胶、硅胶、多孔陶瓷、硅藻土等材料构成。As shown in FIG. 11 , in other embodiments, a permeation tube 65 is provided between the heating piece 63 and the liquid-conducting cotton 62 , and the permeation tube 65 is provided with a permeation hole (not shown in the figure) for permeating smoke liquid. The permeation tube 65 can support the liquid-conducting cotton 62 outward and prevent the liquid-conducting cotton 62 from deforming and denting inward under long-term high-temperature operation. At the same time, it can also slow down the smoke liquid stored in the liquid-conducting cotton 2 through the permeation hole. Released to the heating piece 63, the evaporation amount and penetration amount of the smoke liquid reach a balance during operation. When there is no atomization, the smoke liquid passing through the penetration hole forms a surface tension to achieve another balance to prevent leakage of the smoke liquid. The permeation tube 65 can be made very thin, and the permeation tube 65 can be made of high temperature resistant, non-conductive materials such as plastic, silica gel, porous ceramics, diatomaceous earth and other materials.
在其它实施例中，导液棉2可由两层或两层以上的片状体层叠构成，两层或两层以上的片状体层叠使导液棉2既容易吸收传导烟液，又不容易发生变形而导致损坏和漏液。In other embodiments, the liquid-conducting cotton 2 can be composed of two or more layers of sheet-like bodies. The stacking of two or more layers of sheet-like bodies makes it easy for the liquid-conducting cotton 2 to absorb the conductive smoke liquid, but not easily Deformation may occur, causing damage and leakage.

通过上述实施例可知，在本发明中，卷成管状的导液棉工作时，自外侧向内侧传导烟液，其片状体、管状结构使得传导和加热雾化液的面积大，避免了导液棉绳传导烟液的传导面积小、工作时雾化量较小以及高温工作时容易漏液的缺点。且导液体棉采用上述棉状的材料，具有疏松的纤维结构，烟液通过纤维结构之间的缝隙传导，不需要通过微孔传导，故导液快、可以保持较大的雾化量，相对于多孔陶瓷，避免了雾化液中含有的大分子和微颗粒、糖分等容易聚集、堵塞在微孔内、且在高温下容易产生焦味的缺点。It can be seen from the above embodiments that in the present invention, when the liquid-conducting cotton rolled into a tubular shape is working, it conducts smoke liquid from the outside to the inside. Its sheet-like body and tubular structure make the area for conducting and heating the atomized liquid large, avoiding the problem of conduction and heating of the atomized liquid. The liquid cotton rope has the disadvantages of small transmission area, small atomization volume during operation, and easy liquid leakage when working at high temperatures. Moreover, the liquid-conducting cotton uses the above-mentioned cotton-like material and has a loose fiber structure. The smoke liquid is conducted through the gaps between the fiber structures and does not need to be conducted through micropores. Therefore, the liquid conduction is fast and can maintain a large atomization volume. Compared with It is based on porous ceramics, which avoids the shortcomings of macromolecules, microparticles, sugar, etc. contained in the atomized liquid being easy to aggregate and clog in the micropores, and easily producing a burnt smell at high temperatures.
本发明中，雾化管中间的管孔可作为雾化气道，烟液在导液棉中自外向内传导至发热片，并在发热片上雾化后形成气雾或烟雾，该气雾或烟雾在管孔中自下而上向上排出。本发明中的管状雾化芯可预先组装为一个整体，在电子烟生产中作为一个配件，在组装到电子烟时，只需将该雾化芯的上端与上盖通孔连接，下端与下盖通孔连接即可，结构简单及工艺简单，容易组装到电子烟，可以提高生产效率，容易实现自动化生产。In the present invention, the tube hole in the middle of the atomization tube can be used as an atomization airway. The smoke liquid is conducted from the outside to the inside of the liquid-conducting cotton to the heating piece, and is atomized on the heating piece to form aerosol or smoke. The aerosol or smoke is The smoke is discharged from bottom to top in the tube hole. The tubular atomizing core in the present invention can be pre-assembled as a whole and used as an accessory in the production of electronic cigarettes. When assembled into the electronic cigarette, only the upper end of the atomizing core is connected to the through hole of the upper cover, and the lower end is connected to the through hole of the upper cover. The cover can be connected through the holes, the structure is simple and the process is simple, and it is easy to assemble into the electronic cigarette, which can improve production efficiency and easily realize automated production.
