Heating control method of electronic cigarette and electronic cigarette

Abstract

The invention relates to the field of electronic cigarettes, and particularly discloses a heating control method of an electronic cigarette and the electronic cigarette. A heating wire with a temperature coefficient is selected to manufacture an atomizer. Before the electronic cigarette is started, various parameters of the heating wire are obtained, and the parameters comprise a normal-temperature resistance value of the heating wire converted through a formula. After the electronic cigarette is started, the actual resistance value of the heating wire is obtained, the actual temperature of the heating wire is calculated based on the actual resistance value of the heating wire, if the actual temperature is higher than the set temperature, the actual power of the heating wire is reduced, and otherwise, the actual power of the heating wire is not reduced. Compared with a method of directly detecting the temperature, a new temperature sensor does not need to be introduced, the structure of the electronic cigarette is simplified, the resistance can be converted into the temperature, resistance detection equipment only needs one circuit board, even the circuit can be integrated into anexisting control circuit board, and miniaturization of the electronic cigarette is achieved.

Description

technical field [0001] The invention belongs to the field of electronic cigarettes, and in particular relates to a method for controlling heating of electronic cigarettes and electronic cigarettes. Background technique [0002] Existing electronic cigarettes use an atomizer with a constant temperature coefficient. Under this structure, if the user's suction force is small, the heat generated during the atomization process cannot be taken away, and the heat accumulation will cause the internal temperature of the atomizer to rise. As the temperature rises, harmful substances or other burnt smells will be produced, the probability of atomizer damage and oil leakage will be further increased, and the heating wire will be dry-burned or blown out. As long as there is one of the above factors, it will seriously damage the user experience. Contents of the invention [0003] The object of the present invention is to provide a heating control method for an electronic cigarette and ...
