Heating monitoring method of electronic cigarette and electronic cigarette

Abstract

The invention relates to the field of electronic cigarettes, and particularly discloses a heating monitoring method of an electronic cigarette and the electronic cigarette. A heating wire with a temperature coefficient is selected for manufacturing an atomizer, the normal-temperature resistance value and the normal-temperature temperature of the heating wire are initialized, the set resistance value and the set temperature of the electronic cigarette are initialized, there is a contact resistance value and an expansion coefficient between the heating wire and an elastic needle, there are mapping relations between the normal-temperature resistance value and the normal-temperature temperature and between the set resistance value and the set temperature, and the mapping relations additionallyinclude the contact resistance value of the heating wire and the elastic needle. The actual resistance value of the heating wire is obtained after the electronic cigarette is started, the actual temperature of the heating wire is calculated based on the actual resistance value of the heating wire, the actual temperature is compared with the set temperature, 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. The precision of the detected resistance is improved, so that the precision of the corresponding temperature is improved, and an accurate basis is provided for regulation and control.

Description

technical field [0001] The invention belongs to the field of electronic cigarettes, and in particular relates to a heating monitoring method of the electronic cigarette and the electronic cigarette. 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. At the beginning, the power was reduced by judging that the temperature was reached, but no matter the suction force, it did not change. Later,...

As the temperature rises, it will further produce harmful substances or other burnt smells, further increase the probability of atomizer damage and oil leakage, and further heat wires will dry out or burn out. As long as there is one of the above factors, it will seriously damage the product. user experience
