Description
Technical Field
The utility model belongs to novel cigarette smoking set field, in particular to prevent dry combustion method electronic atomization device.
Background
In recent years, with the development of science and technology and society, people gradually realize the harm of smoking traditional tobacco to human bodies, and in some occasions, the smoking prohibition is gradually limited so as not to bring certain health hidden troubles to people. But due to the appearance of the electronic cigarette, certain psychological and physiological requirements of consumers are met by sucking the atomized smoke, and meanwhile, the dependence on traditional tobacco is reduced, so that the health purpose is achieved.
On the market at present, the tobacco tar that electronic cigarette product mainly utilizes the heater to atomize the storehouse through the electric heating mode with atomizing, produces smog, gets into the consumer oral cavity, reaches the suction and experiences. In the process, tobacco tar basically undergoes physical change from liquid state to gas state without chemical change, so that the components of the smoke are basically harmless to the human body, and the electronic cigarette is a better smoking cessation substitute in the market.
However, in the process of atomizing the tobacco tar, once the amount of the tobacco tar is reduced to be incapable of being absorbed by the atomizing core or the oil guide cotton or the tobacco tar is exhausted, the electronic cigarette can be burned, which can seriously reduce the smoking taste of consumers. Meanwhile, because of the exhaustion of the tobacco tar, the temperature of the atomizing core or the oil guide cotton can be rapidly raised due to the continuous heating of the heating type, and after a certain temperature point is exceeded, the material inside the atomizing core or the oil guide cotton can generate chemical reaction to generate harmful gas, so that the smoking health of consumers is necessarily influenced. Therefore, the dry-burning prevention electronic cigarette appears on the market.
In the process of implementing the present invention, the inventor finds that the prior art has at least the following problems:
1. most of dry-burning-prevention electronic cigarettes in the market judge whether a dry-burning phenomenon exists or not by detecting abnormal fluctuation of resistance values of heating wires, and the reasons for the abnormal fluctuation of the resistance values of the heating wires are many, such as changes of external temperature, changes of components of atomized liquid and the like. Therefore, the misjudgment rate of the detection method is high, the electronic cigarette can be protected against dry burning for multiple times, and the smoking experience of a consumer is reduced.
2. The dry-burning prevention operation is carried out on part of the dry-burning prevention electronic cigarette by detecting the exhaustion of the tobacco tar in the atomization bin. The mode hangs a sheetmetal in atomizing storehouse, and the sheetmetal is as two electrodes respectively with atomizing storehouse bottom surface, and the electrically conductive effect when utilizing the tobacco tar to contact two electrodes simultaneously detects the change of resistance value in order to judge the atomizing storehouse tobacco tar liquid level between two electrodes, thinks the tobacco tar and exhausts when detecting two electrode disconnection, starts the dry combustion method protection. And the second mode is that two strip electrodes are designed on the inner walls of two sides of the atomization bin, the resistance value between the two electrodes is detected to judge the change of the tobacco tar liquid level in the atomization bin, and when the two electrodes are detected to be disconnected, the tobacco tar is considered to be exhausted, and dry burning prevention protection is started. The two detection modes can normally detect when the atomization bin is vertically placed on the ground. However, when a user uses an electronic cigarette, the electronic cigarette is usually held in an inclined state by the user's fingers for the user's mouth to draw, and the direction of inclination is random. Under two kinds of above-mentioned detection methods, when the tobacco tar volume is less, when the electron cigarette is the tilt state, two electrodes are contacted to the tobacco tar very big probably simultaneously, two electrode disconnection, and this is the same with the resistance state when the tobacco tar exhausts, and the resistance value is the infinity, and the electron cigarette then can carry out the dry combustion method operation of preventing, but this belongs to the erroneous judgement completely, leads to the user can't carry out normal suction operation.
