Description

Technical field of non-flammable electronic atomized cigarette

The present invention relates to a non-flammable electronic atomized cigarette containing no harmful tar and containing only nicotine (nicotine). Background technique

Now that "smoking is harmful to health" has become common sense, the world still has

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.

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.

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.

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

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.

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.

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
