Embodiment Construction

[0011] The following is the normal temperature value T under the current conditions 0 is 25°C, the temperature target value T of e-cigarette heating 1 is 265°C, and the resistance value of the heating core of the electronic cigarette at normal temperature is R 0 , when heated to a high temperature state, the resistance value is R 1 . From this, it is determined that the temperature coefficient of resistance (TCR) of the electronic cigarette is TCR value = (R 1 -R 0 ) / (R 0 *(T 1 -T 0 )). The voltage of the square wave output by the PWM module is 8VDC, and the frequency is 25Hz.

[0012] The PWM module with adjustable duty cycle outputs a high level to apply voltage to the heating core, and the heating core is used to heat the electronic cigarette; at the moment when the square wave output by the PWM module is at a high level, the MCU of the electronic cigarette reads the heating The voltage value of the two electrodes of the core to get the actual heating voltage V of ...

Abstract

The invention provides a heating method for an electronic cigarette. The heating method for the electronic cigarette has advantages of high economy, sufficient heating and good taste. The heating method includes the following steps: (1) establishing a TCR curvilinear relationship of the electronic cigarette; (2) outputting a high level to exert voltage to a heating core through a PWM module with an adjustable duty cycle, and using the heating core to heat the electronic cigarette; (3) reading voltage values of two electrodes of the heating core through an MCU of the electronic cigarette instantly when a square wave outputted by the PWM module is the high level, obtaining an actual heating voltage VH and a heating current value IH of the heating core, obtaining a resistance value RH of theheating core according to a formula of R=U/I, and obtaining a temperature value TH of the heating core by means of the resistance temperature coefficient formula; and (4) adjusting input voltage and current after the temperature of the heating core is obtained to enable the temperature of the heating core to be gradually close to a temperature target value T1 of the electronic cigarette heating, and so on, the temperature of the heating core can be consistent with the temperature target value of the electronic cigarette heating and remains at T1. The heating method can be applied to the fieldof electronic cigarettes.

Description

technical field [0001] The invention relates to the field of electronic cigarettes, in particular to a heating method for electronic cigarettes. Background technique [0002] E-cigarettes are becoming more and more popular among smokers. The basic principle of electronic cigarettes is: using a heater to heat the shredded tobacco of special cigarettes, but not to burn them. Compared with regular cigarettes, e-cigarettes are more expensive. The taste of electronic cigarettes is poor when the heating is insufficient or the temperature is too high. If the temperature is too high, harmful substances may be produced, which will affect and harm the smoker, the surrounding environment and the crowd. If a heating method for electronic cigarettes can be designed to ensure sufficient heating and heating on demand, the above problems can be well solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of ...
