Description

A non-combustible electronic spray cigarette

technical field

The utility model relates to a non-combustible electronic spray cigarette which does not contain harmful tar and only contains nicotine (nicotine).

Background technique

In today's situation that "smoking is harmful to health" has become common sense, there are still 1 billion people smoking in the world, and this number is still expanding every year. On March 1, 2003, the World Health Organization (WHO) adopted the first international According to figures provided by WHO, smoking causes 4.9 million deaths every year. 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). When smoking, nicotine enters the alveoli along with a large amount of tar droplets produced when the cigarette burns, and then absorbs it quickly. After being absorbed into the blood, nicotine acts on the receptors of the central nervous system, causing A stimulant-like "high," such as the dizzy or high feeling experienced by smokers.

Nicotine is a small molecule alkaloid, which is basically harmless to the human body in small doses, and has a very short half-life in the blood. The harmful substance of tobacco is mainly tar, and tobacco tar is composed of hundreds of components, dozens of which are carcinogens. It has been confirmed that secondary smoking is more harmful to non-smokers.

In order to find cigarette substitutes that only contain nicotine and do not contain harmful tar, there are many utility models made of relatively pure nicotine, such as "smoking cessation stickers", "nicotine containing cough water", "packaged in high-pressure "Air can spray", "nicotine chewing gum", "nicotine drink" and other products, although these products are not harmful to tar, but due to the slow absorption of nicotine, they cannot establish an effective peak concentration in the blood, and cannot solve the demand for nicotine" It also deprives the habit of "smoking" and "sucking" that smokers have developed, so similar products cannot really be used as smoking cessation products or cigarette substitutes.

Example 1: As shown in Figure 1 is the structure diagram of the device.

Its basic principle is that when the cigarette holder is placed on the mouth, the resistance sensor 19 starts the control circuit board 8, and the control circuit board outputs two driving voltages respectively, one of which supplies power to the electric heating element of the high-temperature gasification nozzle 17, and the other starts The micropump 11 (see Figure 6 for the structure) is pumped into the liquid storage container 13 to the nozzle 17, and the nicotine solution is vaporized into high-temperature steam on the electric heating element of the nozzle and ejected to the open end. The atmosphere expands and condenses into tiny droplets in the form of smoke. The function of the ultrasonic piezoelectric film 20 attached to the nozzle is: first, to make the large liquid droplets in the high-pressure unstable hot air flow fully contact with the heating element to vaporize; second, to directly break and atomize the liquid droplets in the nozzle , The third is to solve the problem of bumping when the liquid is higher than the boiling point. The comprehensive atomization effect can make the diameter of smoke droplets be 0.2-3um. Droplets of this size are more likely to enter the alveoli for absorption. The airflow sensor 18 is sensitive to the diluted air flow entering the air intake hole 16 when the "suction" action occurs. and heater power supply. The delay relationship between the micropump and the heater is: when the heater is started, the micropump starts after a delay of 0.1 to 0.5 seconds, and the heater is turned off after a delay of 0.2 to 0.5 seconds after the control circuit of the micropump is turned off. After quantitative infusion, the liquid is completely vaporized without residue. The volume of the nicotine liquid storage container can be designed into different sizes according to needs, and the nicotine solution can be replenished once a day or once a few days. The liquid crystal display screen 10 can display working state parameters, such as battery capacity, number of puffs per day, average cycle of use, and warning of excessive times. The red light-emitting diode 3 flashes in each suction, and the flash signal is given a 1.2-second sawtooth wave signal by the control circuit, so that the flash is in a gradual brightness change, to simulate the brightness change of the burning flash of smoking.
