Although the electrothermal atomization method has a simple working principle and mature technology applications, the following problems generally exist: 1. The core patent of the atomization technology is controlled by Imperial Tobacco Company, which has a greater risk of intellectual property infringement; 2. The e-cigarette continuously smokes During the process, the heating component can continue to heat up to more than 500 ° C.

本发明的微波谐振致雾化电子烟工作过程描述如下：开机状态下，通过调节档位开关141设置微波功率强度并直观显示于所述显示屏143中。长按主控开关142，所述微波发生器13在所述控制器12作用下产生微波，经微波传输线131传递给能量耦合器224，并通过所述耦合孔225馈入谐振腔221使其发生谐振，进而使所述第二导油件223中的烟油吸波生热，当热量足够高时，即可雾化形成气溶胶；产生的气溶胶通过第二导油件223与第一导油件213内部形成气流通道，然后进入吸嘴24内部的气流通道进入抽吸者口中。The working process of the microwave resonance-atomized electronic cigarette of the present invention is described as follows: In the power-on state, the microwave power intensity is set by adjusting the position switch 141 and displayed directly on the display screen 143. Press and hold the main control switch 142, the microwave generator 13 generates microwaves under the action of the controller 12, and transmits the microwaves to the energy coupler 224 via the microwave transmission line 131, and feeds them into the resonance cavity 221 through the coupling hole 225 to cause them to occur. The resonance causes the e-liquid in the second oil guide 223 to absorb heat and generate heat. When the heat is high enough, it can be atomized to form an aerosol. The generated aerosol passes through the second oil guide 223 and the first guide. An air flow passage is formed inside the oil piece 213, and then enters the air flow passage inside the suction nozzle 24 into the mouth of the sucker.
本发明的有益效果是：The beneficial effects of the present invention are:
1、本发明的微波谐振致雾化电子烟利用谐振型微波与烟油分子相互作用产生的热效应，使烟油在不同深度同时升温生热并雾化形成气溶胶。而电热式雾化基于热传导原理，总是由表及里的传递热量，导油件中的烟油不可避免地存在温度梯度，烟油受热不均匀，甚至会出现局部过热现象，影响抽吸品质。两种方式雾化机理完全不同，故本发明的电子烟抽吸装置可有效规避专利侵权的风险。1. The microwave-resonance atomized electronic cigarette of the present invention uses the thermal effect generated by the interaction between the resonance type microwave and the e-liquid molecules, so that the e-liquid is heated at different depths at the same time to generate heat and atomize to form an aerosol. The electric heating atomization is based on the principle of heat conduction, and the heat is always transferred from the surface and the inside. The e-liquid in the oil-conducting part inevitably has a temperature gradient. . The atomization mechanism of the two methods is completely different, so the electronic cigarette smoking device of the present invention can effectively avoid the risk of patent infringement.
2、本发明的微波谐振致雾化电子烟采用横磁振荡模式TM 010谐振腔发生谐振，电磁场的叠加会使得谐振腔中心周边区域的电场比较强，加之微波谐振致雾化的“体加热”作用，因此本发明的电子烟抽吸装置还具有能量密度大且较集中、加热效率高、热均匀性好、在单位时间内能够产生足够大的烟雾量等优点。 2. The microwave resonance atomized electronic cigarette of the present invention uses the transverse magnetic oscillation mode TM 010 resonance cavity to resonate. The superposition of the electromagnetic field will make the electric field in the center and surrounding area of the resonance cavity stronger. In addition, the microwave resonance atomization "body heating" Therefore, the electronic cigarette smoking device of the present invention also has the advantages of high energy density and concentration, high heating efficiency, good thermal uniformity, and a sufficient amount of smoke per unit time.
3、本发明的微波谐振致雾化电子烟抽吸装置热惯性小、加热即时且可在几秒时间内迅速地将微波功率适配至预设的数值，利于雾化过程的自动化精确控制。3. The microwave resonance atomized electronic cigarette smoking device of the present invention has small thermal inertia, instant heating, and can quickly adapt microwave power to a preset value within a few seconds, which is beneficial to the automatic and precise control of the atomization process.
4、本发明的微波谐振致雾化电子烟烟油通过吸收微波进而使其自身发热，因此即便连续抽吸，雾化温度也不会超过烟油的共沸点(通常低于300℃)，大大降低了烟油高温热解释放醛类等有害物质的可能性。4. The microwave-resonance atomized e-liquid e-liquid of the present invention absorbs microwaves and thereby heats itself, so even with continuous suction, the atomization temperature will not exceed the azeotropic point of the e-liquid (usually lower than 300 ° C), greatly Reduced the possibility of high temperature thermal interpretation of e-liquid to release harmful substances such as aldehydes.
5、本发明的微波谐振致雾化电子烟基于微波谐振特性和烟油吸波生热效应实现雾化，烟油与微波谐振腔不直接接触，不存在烟油在微波谐振腔上烧结粘附及重金属浸出的问题，抽吸者无健康安全隐患；此外，电子烟的非接触雾化特性，使得烟油成分中也可适当添加含糖量高的天然香原料，进而可丰富烟油口味，赋予烟油有别于常见市售产品的独特香韵，进一步提高抽吸品质。5. The microwave resonance atomized electronic cigarette of the present invention is atomized based on the microwave resonance characteristics and the heat absorption effect of the e-liquid absorbing wave. The e-liquid does not directly contact the microwave resonant cavity, and there is no sintering adhesion of the e-liquid on the microwave resonant cavity. The problem of leaching of heavy metals, the smoker has no health and safety risks; In addition, the non-contact atomization characteristic of the electronic cigarette makes it possible to appropriately add natural flavor raw materials with high sugar content to the e-liquid components, which can enrich the e-liquid flavor and give The unique aroma of e-liquid is different from common commercial products, which further improves the quality of smoking.
6、本发明的微波谐振致雾化电子烟抽吸装置自带低温灭菌功能，其利用微波热效应和生物效应双重杀菌作用，可在保证烟油有效成分无破坏、无流失的情况下，将烟油中因唾液残留和/或潮湿环境而滋生的细菌杀死，进而可延缓烟油变质过程，提升烟油品质的稳定性。6. The microwave resonance atomized electronic cigarette smoking device of the present invention has a low-temperature sterilization function, which utilizes the dual sterilization effect of microwave heat effect and biological effect, and can ensure that the effective components of the e-liquid are not damaged or lost. Bacteria in the e-liquid are killed due to saliva residue and / or humid environment, which can delay the e-liquid deterioration process and improve the stability of e-liquid quality.
