Description

Electronic cigarette with nanoscale ultra-fine space heating atomization function

technical field

The present invention relates to an electronic cigarette with nanoscale ultra-fine space heating atomization function, in particular to an electronic cigarette that can realize nanoliter level control of liquid nicotine and is based on miniaturized resistance, laser, radio frequency, electromagnetic induction, infrared, ultrasonic , microwave and other devices implement space ultra-fine and efficient heating and atomization of electronic cigarettes.

Background technique

In recent years, the harm of traditional smoking to the smoker himself and the people around him has become more and more recognized by people. For this reason, in many countries and regions, in the regulations issued by government departments, smoking in any public places is expressly prohibited. Therefore, the smoking cessation campaign is gradually gaining popularity. However, for smokers who are deeply addicted, quitting smoking is indeed a difficult process.

In order to meet the needs of smoking cessation, many products in different forms have been launched on the market so far, such as tablets, appliances, electronic cigarettes, etc. Among them, the electronic cigarette can realize the atomization of nicotine, and retains the characteristics of the traditional smoking method in the process of smoking, which is more in line with the habit of smokers themselves. Alkali has removed the harmful components in traditional tobacco to the greatest extent, and corrected the problem of not distinguishing the good from the bad and inhaling them all into the body, so it is quite attractive in reducing the harm of tobacco. Because of this, e-cigarettes have been favored by consumers in recent years, and are gradually being recognized as effective smoking cessation products.

In the current technical approach to realize the electronic atomization function, it is mainly divided into two categories: heating atomization and ultrasonic atomization. The former, Liu Jing and Lv Yonggang once proposed a kind of scheme (Liu Jing, Lv Yonggang, a kind of pen type miniature steam generator, Chinese patent 03242914.2) that can implement heating atomization to the liquid in the small cavity at the end of 2002, it is easy to implement in conventional The atomization of liquid and liquid nicotine has developed the function of delivering nicotine vapor to the nasal cavity, oral cavity and other parts; since then, although some researchers have also proposed corresponding pen-type heating and atomizing electronic cigarettes, the technical ideas are different from this Much the same. Different from electronic heating to achieve liquid nicotine atomization, a Chinese patent submitted in March 2003 proposed an ultrasonic atomization solution (Han Li, a non-combustible electronic atomized cigarette, Chinese patent 03111173.4), Based on the oscillating excitation of the liquid by ultrasonic waves at a specific frequency, the corresponding atomized nicotine droplets can be generated, and then delivered to the human oral cavity to create the feeling of smoking. This atomization scheme is somewhat similar to the common ultrasonic humidifier in the family, and some technical schemes proposed by others since then are mostly similar to this.

From a comprehensive analysis, the resistance heating atomization scheme introduced above is a kind of contact heating, which mainly heats the liquid flowing through the heating wire, and then further spreads to the surrounding liquid by means of the heat transfer of the fluid. This method has no heating efficiency. It can be used to the maximum; while ultrasonic oscillation atomization has the problems of small amount of atomization and insufficient energy utilization. Therefore, the purpose of the present invention is to provide an electronic cigarette that can implement ultra-fine space heating and atomization of liquid nicotine on the nanometer scale, and the liquid nicotine loaded in the pen-type cigarette rod can be nano-sized by microfluidic technology. Level-up control, the transmission channels where these solutions are located are equipped with miniaturized resistance screens, lasers, radio frequency, magnetic induction, infrared, ultrasound, microwaves and other devices with space heating effects. The electronic cigarette not only improves the atomization efficiency, but also has more comprehensive functions. Nano-scale fluid can achieve efficient atomization effect under the action of this kind of space heating, so it is easy to produce smoke characteristics similar to those of traditional cigarettes. When users inhale the resulting atomized nicotine, Get great satisfaction.
