Description

Electronic atomization device for automatic dry-burn prevention and automatic dry-burn prevention method

technical field

The invention belongs to the field of novel cigarette smoking sets, in particular to an electronic atomization device for automatic dry-burn prevention and an automatic dry-burn prevention method.

Background technique

In recent years, with the development of science and technology and society, people have gradually realized the harm of smoking traditional tobacco to the body, and in some occasions, the smoking of tobacco has been gradually restricted, so as to avoid certain health risks to the crowd. However, due to the emergence of electronic cigarettes, certain psychological and physiological needs of consumers are met by smoking atomized smoke, and at the same time, the dependence on traditional tobacco is reduced to achieve health purposes.

At present, electronic cigarette products on the market mainly use electric heating methods to heat and atomize the e-liquid in the atomization chamber with heating wires, generate smoke, and enter the consumer's mouth to achieve a smoking experience. Since e-liquid basically undergoes a physical change from liquid to gaseous state in this process, there is no chemical change. Therefore, the components of the smoke are basically harmless to the human body, so e-cigarettes are a better smoking cessation substitute on the market.

However, in the process of e-liquid atomization, once the amount of e-liquid is reduced to the point that it cannot be absorbed by the atomizing core or the oil-guiding cotton, or when the e-liquid is exhausted, the e-cigarette will appear dry burning, which will seriously reduce the smoking of consumers. Taste. At the same time, due to the exhaustion of the e-liquid, the temperature of the atomizing core or the oil-conducting cotton will rise rapidly due to the continuous heating of the heating type. Harmful gases, which will definitely affect the consumer's smoking health. Therefore, anti-dry electronic cigarettes have appeared on the market.

In the process of realizing the present invention, the inventor found that the prior art has at least the following problems:

1. Most of the anti-dry-burning electronic cigarettes on the market determine whether there is a dry-burning phenomenon by detecting the abnormal fluctuation of the resistance value of the heating wire. There are many reasons for the abnormal fluctuation of the resistance value of the heating wire, such as changes in external temperature and atomization. Changes in liquid composition, etc. Therefore, the misjudgment rate of this detection method is high, and the electronic cigarette will be protected against dry burning many times, which will definitely reduce the smoking experience of consumers.

2. Some anti-dry-burning electronic cigarettes perform anti-dry-burning operations by detecting the exhaustion of the e-liquid in the atomization chamber. The first method is to hang a metal sheet in the atomization chamber, and the metal sheet and the bottom surface of the atomization chamber are used as two electrodes respectively. Judging the change of the liquid level of the e-liquid in the atomization chamber, when it is detected that the two electrodes are disconnected, the e-liquid is considered to be exhausted, and the anti-dry burning protection is activated. The second method is to design two strip electrodes on the inner walls of both sides of the atomization chamber, and also detect the resistance value between the two electrodes to judge the change of the liquid level of the e-liquid in the atomization chamber. When it is detected that the two electrodes are disconnected It is considered that the e-liquid is exhausted, and the anti-dry burning protection is activated. These two detection methods can be detected normally when the atomization bin is placed vertically on the ground. However, when a user uses an electronic cigarette, the electronic cigarette is usually held by the user's fingers in an inclined state for the user's mouth to smoke. In the above two detection methods, when the amount of e-liquid is small, or the electronic cigarette is in a tilted state, the e-liquid may not be able to contact the two electrodes at the same time, and the two electrodes are disconnected, which is the same as the resistance state when the e-liquid is exhausted. , the resistance value is infinite, and the electronic cigarette will perform anti-dry burning operation, but this is completely a misjudgment, which makes the user unable to perform normal smoking operation.
