[0055] like Figure 1 As shown, a flow chart of a method for controlling cigarette baking based on an electronic cigarette device is described in detail as follows:

[0056] Step S1, inserting a cigarette into the baking chamber triggers the sensor to close and wake up the microprocessor MCU in a dormant state to enter a working state; after the user takes out the electronic cigarette device, he pushes the dust cover on the top to open the baking chamber, inserts the cigarette into the baking chamber, and the sensor placed on the upper side wall of the baking chamber is triggered and closed instantly, and the 3V voltage connected to the sensor is instantly pulled down, triggering the microprocessor MCU in a dormant state, so that the microprocessor MCU enters a normal working mode. The sensor can be a contact spring or a touch switch.

[0057] Step S2, the induction coil detects whether the cigarette contains a heating medium by induction. If so, the information that the cigarette contains a heating medium is fed back to the microprocessor MCU and the next step is executed. If not, the information that the cigarette does not contain a heating medium is fed back to the microprocessor MCU and the next step is executed. After the cigarette is inserted, the induction coil is used to perform induction detection on the cigarette in the baking chamber to determine whether there is a heating medium inside the cigarette for heating. If a heating medium is detected in the cigarette, the information that the cigarette contains a heating medium is fed back to the microprocessor MCU. If no heating medium is detected in the cigarette, it is determined that there is no heating medium in the cigarette, and the detection result information of the cigarette is fed back to the microprocessor MCU. The microprocessor MCU outputs a corresponding instruction based on the received feedback information. In this process, it is determined whether the cigarette contains a heating medium by detecting the change in current in the induction coil. If the current changes, it means that there is a heating medium in the cigarette. If the current does not change, it means that there is no heating medium in the cigarette. When the current change in the cigarette is detected, if the current decreases from 10A to 3A, it is determined that the cigarette contains a heat-relieving medium, and the heating medium is an iron sheet.

[0058] S3, the microprocessor MCU outputs instructions to control the circumferential induction coil heating or the bottom air heating to enter the working state according to the feedback information; the microprocessor MCU controls the coil based on the electromagnetic induction principle wrapped around the baking chamber to enter the working state, or controls the heating element placed under the baking chamber and in contact with the air convection heating to enter the working state according to the feedback information from the detection of the cigarette.

[0059] S4. The microprocessor MCU bakes the cigarettes in the baking chamber according to the parameters set by the circumferential induction coil heating or the bottom air heating until the end. In the embedded program in the microprocessor MCU, the parameters for the induction coil heating or the bottom air heating are set respectively, wherein the parameters for the induction coil heating are the preheating time of 10-30s, wherein the specified time can also be 15s, 20s or 25s, the constant temperature heating temperature is 200℃-400℃, wherein the specific temperature can also be 250℃, 300℃ or 350℃, and the heating time is 3-7 minutes, or 4 minutes, 5 minutes or 6 minutes. The parameters for the bottom air heating are the preheating time of 10-30s, wherein the specified time can also be 15s, 20s or 25s, the constant temperature heating temperature is 200℃-400℃, wherein the specific temperature can also be 250℃, 300℃ or 350℃, and the heating time is 3-7 minutes, or 4 minutes, 5 minutes or 6 minutes.

[0060] The method is simple and can effectively identify two types of cigarettes, eliminating the defect that the electronic cigarette device only supports a single type of cigarette. By automatically identifying and selecting the heating type, the use range of the electronic cigarette device for cigarettes is expanded, providing a better user experience.
