Description

一种非可燃性电子雾化香烟 技术领域  Technical field of non-flammable electronic atomized cigarette

本发明涉及一种不含有害焦油， 只含烟碱 (尼古丁)的非可燃性电 子雾化香烟。 背景技术  The present invention relates to a non-flammable electronic atomized cigarette containing no harmful tar and containing only nicotine (nicotine). Background technique

在当今 "吸烟有害健康"已成为常识的情况下，全世界目前仍有 Now that "smoking is harmful to health" has become common sense, the world still has

10亿人吸烟， 而且每年这个数字还在扩大, 2003年 3月 1日世界卫生 组织（WHO)通过的第一个国际禁烟协定《烟草控制框架公约》，据 WHO提供的数字表明， 吸烟每年造成 490万人死亡， 尽管吸烟可导 致严重的呼吸系统疾病和癌症，要吸烟者完全戒烟是一桩极端困难的 事。 One billion people smoke, and this number is increasing every year. The first international smoking ban agreement, the Framework Convention on Tobacco Control, adopted by the World Health Organization (WHO) on March 1, 2003. According to figures provided by the WHO, smoking causes 4.9 million people die, and although smoking can cause serious respiratory diseases and cancer, it is extremely difficult for smokers to quit smoking completely.

香烟的有效成分是烟碱 (尼古丁)， 吸烟时烟碱随着香烟燃烧时产 生的大量焦油雾滴进入肺泡后迅速吸收， 烟碱吸收入血后作用于中 枢神经系统的受体上， 引起类似兴奋剂的 "陶醉感"，如吸烟者所经 历的头暈目眩或飘飘然的感觉。  The active ingredient of cigarettes is nicotine (nicotine). Nicotine is absorbed during the smoking with a large number of tar mist droplets generated when the cigarette burns, and then absorbed into the alveoli. Nicotine is absorbed into the blood and acts on receptors in the central nervous system. "Intoxication" of stimulants, such as the dizziness or fluttering sensations experienced by smokers.

烟碱是小分子生物碱，在小剂量下对人体基本无害，而且在血液 中的半衰期极短。 烟草的有害物质主要是焦油，烟草焦油是由数百种 成分组成。 其中有数种成分内是致癌物。 目前证实二次吸烟对不吸 烟者的危害更大。  Nicotine is a small-molecule alkaloid that is basically harmless to the human body at low doses and has a very short half-life in the blood. The harmful substance of tobacco is mainly tar, which is composed of hundreds of ingredients. Several of them are carcinogens. Second smoking has been proven to be more harmful to non-smokers.

为了寻找只含烟碱而不含有害焦油的香烟代用品， 有许多发明 是用较纯的烟碱制成诸如 "戒烟贴"、 "烟碱含漱水"、 "包装有抛射剂 的高压气罐喷雾剂"、 "烟碱口香糖"等产品，这些产品虽然没有焦油 的危害，但因烟碱吸收缓慢，在血液中不能建立有效的高峰浓度， 不 能解决需要烟碱 "过瘾" 的感觉， 同时也剥夺了吸烟者已经养成的 "抽"、 "吸"的习惯 5 因而类似的产品不能真正的作为戒烟用品或香 烟代用品。 发明内容 In search of cigarette substitutes containing only nicotine and no harmful tar, many inventions It is made of relatively pure nicotine, such as "quit smoking patches", "nicotine rinse", "high-pressure gas tank sprays with propellants", "nicotine chewing gum", etc. Although these products are free of tar Harmful, but because of the slow absorption of nicotine, effective peak concentrations cannot be established in the blood, and it does not solve the feeling of "addiction" to nicotine. It also deprives smokers of the habit of "smoke" and "suck" 5 Therefore, similar products cannot really be used as smoking cessation products or cigarette substitutes. Summary of the invention

本发明的目的是克服避免了上述缺点， 提供一种可模拟吸烟并 有吸烟效果,更接近真实的人性化电子雾化香烟。  The object of the present invention is to overcome and avoid the above disadvantages, and provide a humanized electronic atomized cigarette that can simulate smoking and has a smoking effect, which is closer to the real humanity.

本发明的特点是， 构成香烟的尾端烟嘴初设置的气流传感器连 至电路板上用于启动经供液管与贮存烟碱溶液相接的雾化器高频振 荡器， 高频振荡器接计数电路和显示屏， 香烟前端为装有电池并带有 发光二极管的端罩。 它的基本工作原理是当把烟嘴放在嘴上吸气时， 气流传感器输出电信号启动电路， 装置在电路板上的高频振荡电路 启动向雾化器提供驱动电压， 另一组直流渐变信号供给红色发光二 极管发出渐变的红光。 雾化器上的双压电片发射超声波用于雾化，贮 存于塑胶容器中的烟碱溶液经供液管输入雾化器中， 经微喷雾化成 直径为 1-15 μ πι的液滴， 其中 75%的液滴直径在 6 μ πι以下，与进气 孔的空气流混合后， 能到达细支气管和肺泡中，每次的供液量在 3-50 μ 1 之间， 这样就能在 10 分钟之内使烟碱在血液中的浓度达到 30ng/ml左右，通过液晶显示屏可分别显示出烟碱溶液的消耗量， 每 夭吸烟的次数，对使用者提供警示信息。 使用者可通过单向阀补充烟 碱溶液。 The invention is characterized in that the airflow sensor initially provided at the end of the cigarette is connected to a circuit board for activating a high-frequency oscillator of the atomizer connected to the stored nicotine solution through a liquid supply pipe, and the high-frequency oscillator is connected to Counting circuit and display screen. The front end of the cigarette is an end cap with a battery and a light emitting diode. Its basic working principle is that when the cigarette holder is put on the mouth for inhalation, the airflow sensor outputs an electric signal to start the circuit, and the high-frequency oscillation circuit on the circuit board starts to provide the driving voltage to the atomizer, and another set of DC gradual signals The red light emitting diode is supplied with a gradual red light. The double piezoelectric plate on the atomizer emits ultrasonic waves for atomization. The nicotine solution stored in the plastic container is input into the atomizer through the liquid supply tube, and is micro-atomized into droplets with a diameter of 1-15 μπι. 75% of the droplets are less than 6 μm in diameter. After mixing with the air flow from the air inlet, they can reach the bronchioles and alveoli. The amount of fluid supplied at each time is between 3-50 μ1. The concentration of nicotine in the blood reaches about 30ng / ml within 10 minutes. The consumption of nicotine solution can be displayed on the LCD screen. 夭 The number of smoking, provide warning information to users. The user can replenish the nicotine solution through the one-way valve.

该装置可逼真的模拟传统的吸烟方式和效果， 使吸烟者有吸烟 的感觉，而且还无副作用，可实现 "吸烟无害健康"。 附圏说明  The device can realistically simulate the traditional smoking method and effect, so that the smoker feels smoking, and also has no side effects, and can realize "smoking is harmless to health". Attached description

The purpose of the high-frequency oscillator with automatic frequency fine-tuning is to keep the piezoelectric chip at the resonance point. The carburetor 14 is a micro-spray and atomizer composed of a double piezoelectric sheet. Its structure is shown in Figure 3. Its working principle is to use two piezoelectric sheets to drive the vibrating diaphragm and The atomized diaphragm, the circular piezoelectric diaphragm and the vibrating diaphragm are bonded to form a piezoelectric transducer, and a high-speed longitudinal pressure wave is provided in the liquid ejection direction so that the liquid is ejected through the micro-jetting holes at high speed. The circular piezoelectric sheet is bonded to the atomized membrane with micro-spray holes to form another piezoelectric transducer. Radial vibration waves are provided to the droplets that are about to leave the micro-nozzles, causing the droplets to further break. Adding a loose fiber mass to the liquid supply cavity composed of the vibrating diaphragm and the atomizing diaphragm can improve the energy and liquid distribution of each micro-orifice in the micro-orifice array to make it even, and the vibrating diaphragm and atomizing membrane The wafer may be made of a single crystal silicon wafer or a corrosion-resistant metal alloy. By changing the driving voltage and frequency of the circular piezoelectric sheet and the circular piezoelectric sheet, the droplet distribution curves with different diameters can be obtained. When the diameter of the micro-nozzle is 4-10 μ η, the diameter of the mist droplets is in the range of 1-15 μ η. After commissioning, it can be used after being filled with the nicotine solution.
