S=A-VB (1)

This solution is a transformation and upgrade based on the existing intelligent early warning system for preventing dry burning of electronic cigarettes. The intelligent early warning system for preventing dry burning of electronic cigarettes generally includes a cigarette rod body, and the cigarette rod body is equipped with a pod, a battery, an air switch, a heating element and a control circuit board. When the intelligent early warning system for preventing dry burning of electronic cigarettes is working normally, information about the heating element such as the duration of each heating, heating temperature and heating power can be collected and saved. Before the intelligent early warning system for dry-burning electronic cigarettes leaves the factory, the consumption rate of e-liquid under different heating temperatures and heating power is obtained through experiments, and stored in the form of a table. When the user is smoking, the heating element information module starts to collect the heating duration, heating temperature and heating power of the heating element. According to the corresponding heating temperature and heating power, the corresponding smoke liquid consumption speed can be obtained, and the information is packaged and sent to MCU. Each time the heating element starts to generate heat, the timer can also obtain the heating duration B, so that the MCU can obtain the remaining amount of smoke S of the cartridge according to the formula S=A-VB. Therefore, a complete cycle is counted from the beginning to the end of each smoking action, and the remaining amount of e-liquid S of the cartridge is automatically calculated at the end of the cycle. When the smoking action is started again next time, the current amount of e-liquid in the formula is the remaining amount of e-liquid S of the last cartridge, and iterative calculation in turn can obtain the remaining amount of e-liquid after each smoking action is completed.

As an optional solution, the comprehensive information of the cartridge includes information on the ID, flavor, amount of e-liquid and elapsed time of a single cartridge. Information such as the ID, flavor, amount of e-liquid, and elapsed time of the cartridge are preset before the cartridge is ejected from the factory. By reading the above information, the relevant factory information of the intelligent early warning system for preventing dry burning of the electronic cigarette can be obtained. Among them, the specific role of D is anti-counterfeiting or matching identification of pods and battery devices.

As an optional solution, the cartridge includes a memory chip EEPROM built into the cartridge and used to store comprehensive information of the cartridge. Every time the user inserts the pod into the battery device, the battery device will communicate with it to obtain comprehensive information of the pod, as well as the heating duration, heating temperature and heating power of the heating element of each smoking action. When the cartridge is inserted into the battery unit, all information can be transferred and summarized into the MCU.

In an optional solution, the cartridge and the MCU are connected through a shared interface, and the shared interface is connected by UNI/O bus communication. Every time the user inserts the pod into the battery device, the device communicates with it by means of IIC, UNI/O or SI/O. Among them, UNI/O is a single I/O UNI/O bus, this innovative bus uses a single I/O pin for all communication, multiplexing clock and data on a single line by using Manchester encoding. SI/O stands for standard input and output. An interface can be used for multiple purposes, either as a power line or as a data line for data and information exchange.

In an optional solution, the early warning threshold is a dry burning alarm point, and the dry burning alarm point is a preset value of the remaining smoke liquid of the cartridge. Before the intelligent early warning system for dry burning electronic cigarettes leaves the factory, the warning threshold is set and stored in the MCU. When the calculated real-time remaining smoke liquid volume S of the cartridge is compared with the early warning threshold, if it is less than or equal to the early warning threshold, a signal is sent to the alarm module to give an alarm.

Optionally, the battery device further includes a wireless transmission module for communicating with the mobile phone, and the wireless communication unit includes Bluetooth, WIFI or NFC. When the cartridge is inserted, the relevant information will be detected and stored. Then the mobile phone can obtain data through Bluetooth or other wireless communication methods, read ID and current e-liquid volume information, etc. Among them, whether the information is transmitted in the form of NFC tags or through preset information, Bluetooth connection, acquisition on the mobile phone, or more than two methods, including various methods of acquiring information tags.

In an optional solution, the alarm module includes one or more of flashing lights, buzzers and vibration motors. The battery device determines whether the remaining amount of smoke liquid reaches the dry burning alarm point, that is, the warning threshold. If it is reached, the heating element will stop working if smoking is not allowed, and at the same time start an alarm, including flashing lights and buzzer beeping, or vibration motor vibration or other methods.

As an optional solution, a flashing light, buzzer or vibration motor is installed on the cigarette rod of the intelligent early warning system for preventing dry burning of electronic cigarettes. It can be installed and fixed by bonding, embedded bolt connection or welding.

Optionally, the battery device is provided with a temperature sensor, a voltage sensor, a current sensor and a timer that are all electrically connected to the MCU. The switch is in the form of a microphone/button, or the heating element automatically senses the breathing airflow switch. When it is detected that the heating element starts to work, the timer starts timing, and the heating element stops working and the timer stops timing, and the duration of each smoking can be obtained, which is the heating duration of the heating element. Both the MCU and the wireless transmission module are located in the MCU. The MCU collects the relevant information of the heating element, the relevant information of the cartridge, and the heating duration of the heating element, then calculates the remaining amount of the smoke liquid, and sends an alarm signal to the alarm module. At the same time, the wireless transmission module can transmit the relevant information of the intelligent early warning system of anti-dry burning electronic cigarettes to the mobile phone client in real time, so as to facilitate users to understand the situation.

The following describes the early warning process of the intelligent early warning system for preventing dry burning of electronic cigarettes, as shown in Figure 2:

Insert the pod into the battery, and the battery can obtain the information of the pod. At the same time, when the cartridge is inserted, the relevant information will be detected and stored, and the mobile phone can obtain data through Bluetooth or other wireless communication methods. Smoking starts. The battery device calculates the remaining smoke liquid volume S=A-VB of the pod according to formula (1), writes it into the pod at the same time, updates the information of the pod, and compares it with the warning threshold. Among them, the calculation formulas of smoke liquid consumption and time, smoking temperature and power are pre-stored in the battery device. Whether the current smoking action is stopped is known through the switch information of the heating element. If this smoking technique is used, the heating duration B of this heating element can be brought into the above formula to obtain the remaining amount of smoke liquid and write it into the cartridge. If the smoking action is not over yet, the remaining amount of smoke liquid S of the cartridge is calculated in real time by the above formula. If S reaches the warning threshold, the heating element will be immediately controlled to stop working, an alarm will be output, and the remaining amount of smoke liquid will be written into the smoke. inside the bomb.
