- Cotton cores and ceramic cores are the mainstream atomizer cores currently on the market. Compared with cotton cores, although ceramic cores have significant advantages in preventing leakage and anti-coking, they also have significant disadvantages. For example, relatively speaking, the atomization volume of ceramic cores is smaller than that of cotton cores. If you want to achieve a higher atomization volume, you need to use high power output.
- the atomizing cores of current electronic atomization devices are mostly ceramic atomizing cores, which are composed of porous ceramics and thick film heating circuits. The atomized liquid is gradually transferred from the liquid storage chamber to the heating circuit under the action of the capillary force of the micro-through holes in the porous ceramics. Atomization is completed at the membrane.
- the liquid conduction ability of ceramic atomizing cores is often worse than that of cotton cores, so it is difficult for ceramic atomizing cores to use high power density output. Once high power density output is used, the heating film of the ceramic atomizing core will dry out, resulting in fog. Core failure.

Description
本发明涉及雾化技术领域,尤其涉及一种电子雾化装置及其雾化器和雾化芯。The present invention relates to the field of atomization technology, and in particular to an electronic atomization device, its atomizer and atomization core.
棉芯和陶瓷芯是目前市面上的主流雾化芯,与棉芯相比,陶瓷芯尽管在防漏液和抗结焦性能上有显著优势,但是也有它的显著劣势。例如,相对而言,陶瓷芯雾化量要比棉芯小。若想达到较高的雾化量,就需要采用高功率输出。而当前的电子雾化装置的雾化芯多为陶瓷雾化芯,由多孔陶瓷与厚膜发热电路组成,多孔陶瓷中微通孔的毛细力作用下雾化液逐渐由储液腔传输至发热膜处完成雾化。陶瓷雾化芯的导液能力往往比棉芯要差,所以陶瓷雾化芯很难采用高功率密度输出,一旦采用高功率密度输出会使得陶瓷雾化芯的发热膜发生干烧,从而导致雾化芯失效。Cotton cores and ceramic cores are the mainstream atomizer cores currently on the market. Compared with cotton cores, although ceramic cores have significant advantages in preventing leakage and anti-coking, they also have significant disadvantages. For example, relatively speaking, the atomization volume of ceramic cores is smaller than that of cotton cores. If you want to achieve a higher atomization volume, you need to use high power output. The atomizing cores of current electronic atomization devices are mostly ceramic atomizing cores, which are composed of porous ceramics and thick film heating circuits. The atomized liquid is gradually transferred from the liquid storage chamber to the heating circuit under the action of the capillary force of the micro-through holes in the porous ceramics. Atomization is completed at the membrane. The liquid conduction ability of ceramic atomizing cores is often worse than that of cotton cores, so it is difficult for ceramic atomizing cores to use high power density output. Once high power density output is used, the heating film of the ceramic atomizing core will dry out, resulting in fog. Core failure.
而现有陶瓷雾化芯都是单侧雾化或者单面雾化。且雾化芯安装采用的是雾化面朝上、雾化面朝下或者采取的是侧面雾化。现有陶瓷雾化芯因为结构设计原因,很难实现高功率输出带来高烟雾量的效果。The existing ceramic atomizing cores all use single-side atomization or single-sided atomization. The atomizing core should be installed with the atomizing surface facing up, the atomizing surface facing down, or using side atomization. Due to structural design reasons, it is difficult for the existing ceramic atomizing core to achieve the effect of high power output and high smoke volume.
此外,对于高糖度雾化液,发热体在多次抽吸后很容易结焦,发热体结焦后严重影响口感,这是导致此类雾化芯在抽吸过程中口感前后一致性差的主要原因。In addition, for atomized liquids with high sugar content, the heating element is easy to coke after multiple puffs, and the coking of the heating element seriously affects the taste. This is the main reason for the poor taste consistency of this type of atomizer core during the puffing process.
本发明要解决的技术问题在于,提供一种雾化量高、前后口感一致性好的电子雾化装置及其雾化器和雾化芯。The technical problem to be solved by the present invention is to provide an electronic atomization device with high atomization amount and good consistency of taste before and after, as well as its atomizer and atomization core.

图1示出本发明的一种雾化芯,用于电子雾化装置,包括多孔基体1,多孔基体1包括至少两个雾化面;雾化芯包括至少两个发热体2,至少两个发热体2分别设置于至少两个雾化面上。具体地,发热体2可选用为发热膜,多孔基体1的外表面至少有两个表面是平整的,即至少两个雾化面为平整的表面,以便发热膜设置在其上。Figure 1 shows an atomizing core of the present invention, used in an electronic atomization device, including a porous matrix 1, which includes at least two atomizing surfaces; the atomizing core includes at least two heating elements 2, and at least two The heating elements 2 are respectively arranged on at least two atomization surfaces. Specifically, the heating element 2 can be selected as a heating film, and at least two of the outer surfaces of the porous substrate 1 are flat, that is, at least two atomization surfaces are flat surfaces, so that the heating film can be disposed thereon.

Heating element 2 can achieve double-sided atomization and increase the amount of smoke. The atomizing core can also use a single heating film for atomization. When single-sided atomization is used, the heating element 2 located on the front 101 or the back 102 of the porous substrate 1 conducts electricity and participates in the atomization. At this time, the atomization can be carried out between the two heating elements 2 Free switching between them can effectively extend the life of the heating element 2. Understandably, the size of the heating element 2 can be smaller than or equal to the size of the porous substrate 1, that is, the heating surface area of the heating element 2 is smaller than the front surface 101 area of the porous substrate 1. The size of the heating element 2 can be adjusted according to actual conditions, thereby adjusting the heating Body 2 can generate heat area.
进一步地,电极3可以采用无引脚设计,例如可以使用导电夹具夹在雾化芯两端;电极3也可以采用有引脚设计,如图3和图4所示,例如发热体2可以采用侧面端面电极3设计,即发热体2的左端面和右端面分别设置有电极3,从而构成发热体2的正负极。通过在该电极3上设置连接线,可以将发热体2与外部的电源电连接,从而可以对发热体2进行供电,使得发热体2进行发热。Furthermore, the electrode 3 can be designed without pins, for example, conductive clamps can be used to clamp both ends of the atomizer core; the electrode 3 can also be designed with pins, as shown in Figures 3 and 4, for example, the heating element 2 can be The side end surface electrode 3 is designed, that is, the left end surface and the right end surface of the heating element 2 are respectively provided with electrodes 3, thus forming the positive and negative electrodes of the heating element 2. By arranging a connecting wire on the electrode 3, the heating element 2 can be electrically connected to an external power source, so that the heating element 2 can be supplied with power to cause the heating element 2 to generate heat.
进一步地,多孔基体1可以为多孔陶瓷,起储油、导油作用。发热体2可以是发热线路,例如厚膜发热线路,或者是具有多孔结构的整版面发热层,或者是发热丝和发热片。对于发热体2为面发热的多孔发热层,该发热体2可为金属、金属玻璃、金属陶瓷、或者为导电陶瓷及其复合氧化物。金属陶瓷为金属或者金属合金中的至少一种与陶瓷材料复合制得,其中陶瓷材料起电阻调节作用和强度增强作用,为氧化铝、氧化锆、氧化硅、氧化钇、氧化镧、氧化铈和氧化镁中的至少一种。Furthermore, the porous matrix 1 can be porous ceramics, which plays the role of oil storage and oil conduction.

By regulating the aerosol particle size Distribution can control taste.
具体地,多孔基体1的孔隙率可以为30~85%,孔径范围为10~100μm,多孔材料的通孔率高,可作为雾化液的导通渠道;发热体2的孔隙率为5~75%,孔径范围为5~100μm。Specifically, the porosity of the porous matrix 1 can be 30 to 85%, and the pore diameter ranges from 10 to 100 μm. The porous material has a high porosity and can be used as a conduction channel for the atomized liquid; the porosity of the heating element 2 is 5 to 75%, the pore size range is 5~100μm.

Specifically, as shown in Figure 4, a slot 11 is provided at the middle position of the lower end of the porous substrate 1 to form a porous substrate 1 with a semi-hollow structure; the end of the porous substrate 1 that is in communication with the atomized liquid is provided with a slot 11 to enable This prevents the atomizer core heating element 2 from dry burning due to insufficient oil supply, and ensures that high power is used to obtain a large atomization amount without dry burning. It is understandable that the depth of the groove 11 can be adjusted according to actual conditions, and is not specifically limited here.

At the same time, the atomizing core can be designed with multiple heating bodies 2. The atomizing core can include at least two heating bodies 2, which can be used for simultaneous atomization on multiple sides or single-sided atomization. When multiple heating bodies 2 are used for simultaneous atomization, it can Achieving high power density output brings high atomization effect; when using a single heating element 2 for atomization, the atomization can be freely switched between multiple heating elements 2, so it can effectively delay the problem of carbon deposition and coking of the heating element 2, and effectively improve The taste of the atomizer core is consistent before and after smoking.
