The battery assembly is installed with a battery that supplies power to the atomizer. The atomizer includes an atomizing core installed on the atomizing seat. The atomizing core can be powered on. The solution to be atomized, that is, the liquid to be atomized, is heated and atomized into a vapor mist or aerosol.
电子雾化设备具体包括戒烟用的电子烟具、医疗用的药液雾化设备等,其基本任务是提供加热过程,将电子雾化设备内储存的烟液、药液等溶液转化为汽雾、气溶胶、蒸气等。Electronic atomization equipment specifically includes electronic cigarette equipment for smoking cessation, medical liquid atomization equipment, etc. Its basic task is to provide a heating process to convert the liquid smoke, liquid medicine and other solutions stored in the electronic atomization equipment into vapor, mist, Aerosols, vapors, etc.
现有的雾化芯,其中一种作为导液体本体的材料一般为长条形的玻纤绳或棉绳,另外一种由陶瓷制成的雾化芯,其加热用的发热材料均为电热丝,电热丝直接缠绕于玻纤绳或棉绳上或置于圆筒形的陶瓷内壁,由于电热丝与导液本体接触面积小,故存在发热面积小,雾化量小,发热不均匀的问题。另外,现有的雾化芯,均需设置在雾化座形成的雾化腔内,在其雾化芯本体上没有设置雾化腔的结构,故待雾化液加热蒸发后形成的汽雾或气溶胶被气流直接向上带出,其中未被雾化或冷凝后的小液滴也容易被气流直接夹带向上而无阻碍地被吸出,不能有效地防水雾。现有多孔陶瓷制成的雾化芯,因其烧结温度和材料的影响,其强度较差,在使用中容易因外力作用或在待雾化液的浸泡下发生碎裂,导致损坏或降低雾化效果。In the existing atomizing cores, one of the materials used as the liquid-conducting body is generally a long glass fiber rope or cotton rope, and the other is an atomizing core made of ceramics, and the heating materials used for heating are electric heating wires. , the heating wire is directly wound on the glass fiber rope or cotton rope or placed on the cylindrical ceramic inner wall. Due to the small contact area between the heating wire and the liquid conducting body, there are problems of small heating area, small atomization and uneven heating. In addition, the existing atomizing cores all need to be arranged in the atomizing cavity formed by the atomizing seat, and the structure of the atomizing cavity is not arranged on the atomizing core body, so the vapor mist formed after the atomization liquid is heated and evaporated Or the aerosol is directly carried upward by the air flow, and the small droplets that are not atomized or condensed are also easily entrained by the air flow directly upward and sucked out without hindrance, which cannot effectively prevent fogging. The existing atomizing core made of porous ceramics has poor strength due to the influence of sintering temperature and material, and is prone to breakage due to external force or immersion in the liquid to be atomized during use, resulting in damage or reduced fogging. effect.

The cross-sectional area of the lower square tube 14 of the housing 1 is larger than the cross-sectional area of the upper circular tube 13. In accordance with the housing 1, the cross-section of the lower portion 23 of the liquid conducting 2 is larger than that of the upper portion 22, so that the The heating area increases, the volume of the atomization cavity 16 increases, and the amount of vapor mist or aerosol generated per unit time increases, so that the user experience and taste are better.

The casing 1 is made of metal material, which can better protect the liquid guide 2 made of porous ceramic material, so that the liquid guide 2 is not easily broken during use. In other embodiments, the housing 1 can also be made of heat-resistant dense ceramic material.
耐热致密陶瓷材料也具有很高的强度,可以有效保护导液体2。The heat-resistant dense ceramic material also has high strength and can effectively protect the conductive liquid 2 .
外壳1、导液体2、发热片3和电极引线4的材料置于模具内成型后一体烧结制成,这样雾化芯成型为一体,并自带有雾化腔,在装配到雾化器上时,上部只需连接到吸嘴,而下部只需安装到雾化座上,使得零配件减少,安装简单,有利于实现自动化生产。另外,本发明的雾化芯,在装配到雾化器上后,雾化芯的外壳1直接置于雾化器的储液腔内,与储液腔内的待雾化液直接接触。而雾化芯的外壳1由金属材料制成,使得发热片3工作时,其多余的热量可很快通过导液体2传导至外壳1,而外壳1可将热量传导给待雾化液,这样可在使用中很快加热待雾化液,使其流动性增加,因此本发明的雾化芯可以使用粘稠度较大的待雾化液。The materials of the shell 1, the liquid guide 2, the heating element 3 and the electrode lead 4 are placed in the mold and then sintered together, so that the atomizing core is formed as a whole, and has its own atomizing cavity, which is assembled on the atomizer. At the same time, the upper part only needs to be connected to the suction nozzle, and the lower part only needs to be installed on the atomizing seat, which reduces the number of spare parts and makes the installation simple, which is conducive to the realization of automatic production. In addition, after the atomizing core of the present invention is assembled to the atomizer, the shell 1 of the atomizing core is directly placed in the liquid storage chamber of the atomizer, and is in direct contact with the liquid to be atomized in the liquid storage chamber. The outer shell 1 of the atomizing core is made of metal material, so that when the heating element 3 is working, its excess heat can be quickly conducted to the outer shell 1 through the liquid conducting liquid 2, and the outer shell 1 can conduct the heat to the liquid to be atomized, so that The liquid to be atomized can be quickly heated during use to increase its fluidity, so the atomizing core of the present invention can use the liquid to be atomized with a relatively high viscosity.

外壳1、导液体2、发热片3和电极引线4的材料置于模具内成型后一体烧结制成,这样雾化芯成型为一体,并自带有雾化腔,在装配到雾化器上时,上部只需连接到吸嘴,而下部只需安装到雾化座上,使得零配件减少,安装简单,有利于实现自动化生产。另外,本发明的雾化芯,在装配到雾化器上后,雾化芯的外壳1直接置于雾化器的储液腔内,与储液腔内的待雾化液直接接触。而雾化芯的外壳1由金属材料制成,使得发热片3工作时,其多余的热量可很快通过导液体2传导至外壳1,而外壳1可将热量传导给待雾化液,这样可在使用中可预热或很快加热待雾化液,使其流动性增加,因此本发明的雾化芯可以使用粘稠度较大的待雾化液。The materials of the shell 1, the liquid guide 2, the heating element 3 and the electrode lead 4 are placed in the mold and then sintered together, so that the atomizing core is formed as a whole, and has its own atomizing cavity, which is assembled on the atomizer. At the same time, the upper part only needs to be connected to the suction nozzle, and the lower part only needs to be installed on the atomizing seat, which reduces the number of spare parts and makes the installation simple, which is conducive to the realization of automatic production. In addition, after the atomizing core of the present invention is assembled to the atomizer, the shell 1 of the atomizing core is directly placed in the liquid storage chamber of the atomizer, and is in direct contact with the liquid to be atomized in the liquid storage chamber. The outer shell 1 of the atomizing core is made of metal material, so that when the heating element 3 is working, its excess heat can be quickly conducted to the outer shell 1 through the liquid conducting liquid 2, and the outer shell 1 can conduct the heat to the liquid to be atomized, so that The liquid to be atomized can be preheated or quickly heated during use to increase its fluidity, so the atomizing core of the present invention can use the liquid to be atomized with a relatively high viscosity.
