  • the embodiment of the present disclosure provides a method for controlling an electronic cigarette, including the following steps:
  • Whether there is a work start signal of the electronic cigarette can be detected through a senor or a button switch. If the sensor senses a work start signal or the button switch is triggered, it is indicated that there is a work starting signal. That is to say, the work start signal may be generated by the sensor, also may be generated by a manual control of the button. In case of manual generation, a button is arranged on the surface of the electronic cigarette, and when the button is pressed down, it is equivalent to give a signal to start smoking, that is, to generate a work starting signal. In case of automatic generation, a user sucks a mouthpiece on the electronic cigarette, such that the airflow pressure inside the electronic cigarette changes and thus a work start signal is generated.
  • a controller connected to the sensor or the button switch can acquire the work starting signal.
  • the controller can be a single-chip and the like. It is understandable that the method of acquiring the work start signal of the electronic cigarette can also be performed by an acousto-optic element, and the method is not specifically defined here.
  • the controller of the electronic cigarette cyclically scans the airflow sensor of the electronic cigarette so as to acquire the work start signal of the electronic cigarette.
  • the time interval between starting work this time and stopping work last time refers to a time interval between the current puff and the last puff, that is, the time difference between two puffs.
  • the time of each smoking can be recorded locally or in the cloud.
  • the method of acquiring a time interval between starting work this time and stopping work last time may include: acquiring according to a time interval between starting sending a sensing signal this time and stopping sending a sensing signal last time of an airflow sensor of the electronic cigarette, or acquiring according to a time interval between starting work this time and stopping work last time of an electrical heating element of the electronic cigarette.
  • the airflow sensor of the electronic cigarette senses a work start signal generated due to the user's smoking, then the controller acquires the work start signal through the airflow sensor and thus controls the heating element of the electronic cigarette to operate to vaporize the e-liquid to form an aerosol; after each puff, the electrical heating element stops working, and the controller records the time when the electrical heating element stops working.
  • the controller again controls the electrical heating element to work and records the time when the electrical heating element starts working.
  • the time interval is the time difference between the time when the electrical heating element stops working and the time when the electrical heating element starts working. It is understandable that, in one type of embodiments, when the work start signal of the electronic cigarette is acquired through the triggering of the button switch, for two adjacent puffs, the time interval is the time difference between the end time of the work start signal and the start time of the work start signal. Therefore, the method of acquiring a time interval between starting work this time and stopping work last time is not specifically defined here.
  • S 3 comparing the time interval with a preset time interval, when the time interval is greater than a first preset time interval, controlling the electronic cigarette to work at a first power, and when a duration of the first power is greater than a first preset duration, turning off the electronic cigarette; when the time interval is greater than a second preset time interval but less than or equal to the first preset time interval, controlling the electronic cigarette to work at a second power, and when a duration of the second power is greater than a second preset duration, turning off the electronic cigarette; wherein, the first power is greater than the second power.
  • the first preset time interval is greater than the second preset time interval.
  • the first preset time interval and the second preset time interval can be set according to requirements, for example, the first preset time interval can be set to 40 seconds, 50 seconds or 60 seconds, etc.
  • the second first preset time interval can be set to 10 seconds, 15 seconds or 20 seconds, etc.
  • the second preset time interval can also be set to 0 second, which is not specifically defined here.
  • the first preset time interval is not less than 60 seconds, and/or the second preset time interval is not less than 15 seconds, which is more suitable for user's habits and thus can provide an appropriate amount of smoke for a user to inhale and achieve a good experience.
  • the first power and the second power can be set according to the types of the electronic cigarette and the types of the e-liquid, which are not specifically defined here.
  • a voltage of a battery supplying power to the electronic cigarette is collected, then a duty ratio of a pulse width modulated signal is calculated according to the voltage of the battery and the preset first power or second power, and then the conduction of a semiconductor switch which controls the operation of the electrical heating element is controlled according to the calculated pulse width modulated signal, so as to perform a heating control on the electrical heating element.
  • the first power and the second power may be variable or constant. In one embodiment of the present disclosure, the first power and the second power are constant, for easy control.
  • the first preset duration is less than the second preset duration.
  • the first preset duration and the second preset duration can be set according to requirements, for example, they can be set to 6 seconds, 7 seconds, 8 seconds, 9 seconds or 10 seconds, etc. In the present embodiment, the first preset duration is 6 seconds, and the second preset duration is 9 seconds. If a duration of the first power is greater than the first preset duration, turn off the electronic cigarette, that is, control the semiconductor switch which controls the operation of the electrical heating element to be off. Similarly, if a duration of the second power is greater than the second preset duration, turn off the electronic cigarette. That is to say, the electronic cigarette is controlled to have a shorter duration of working at a high power than at a low power, which better ensures the amount of smoke and avoids mouth burning due to long time of working.
  • the present embodiment is similar to Embodiment 1 in steps, except that: the S 3 of the method for controlling the electronic cigarette in the present embodiment further includes: when the time interval is less than or equal to the second preset time interval, controlling the electronic cigarette to work at a third power, and when a duration of the third power is greater than a third preset duration, turning off the electronic cigarette; wherein, the second power is greater than the third power.
  • the third power and the third preset duration can be set according to requirements, as long as the second power is greater than the third power.
  • the second preset duration is less than the third preset duration.
  • the present embodiment sets multiple different powers corresponding to multiple different time intervals in a process of smoking to atomize the e-liquid. The higher the power, the shorter the duration; the lower the power, the longer the duration. The present embodiment better stabilizes the amount of smoke and avoids the problem of mouth burning due to high temperature.
  • the present embodiment is similar to Embodiment 1 in steps, except that: before acquiring a time interval between starting work this time and stopping work last time, the present embodiment further includes the following steps.
  • an e-liquid is filled in the electronic cigarette and the total amount of the e-liquid is written in a memory of the electronic cigarette.
  • the consumption of the e-liquid is directly proportional to the power; each time the user takes a puff, the controller of the electronic cigarette calculates the consumption of the e-liquid per puff according to the power and the time of each puff, and subtracts the consumption per puff from the total amount before the puff after finishing the puff, thereby calculating the current remaining amount of the e-liquid and writes it into the memory of the electronic cigarette.
  • the controller acquires the current remaining amount of the e-liquid by reading the remaining amount of the e-liquid written in the memory. It is understandable that the remaining amount of the e-liquid can be calculated by different methods according to different types of e-liquids and different types of electronic cigarettes. Therefore, the method of acquiring the remaining amount of the e-liquid is not specifically defined here.
  • the electronic cigarette is also controlled to keep a turnoff state to avoid dry burning and protect user's health, even if the work start signal is acquired.
  • the electronic cigarette when the e-liquid remaining amount is greater than or equal to the first preset remaining amount but less than a second preset remaining amount, control the electronic cigarette to work at a fourth power; wherein, the fourth power is less than the first power. That is to say, when the e-liquid remaining amount is greater than or equal to the first preset remaining amount but less than a second preset remaining amount, one cannot smoke at will.
  • the electronic cigarette prevents the electrical heating element from dry burning and can make full use of the remaining e-liquid and avoid waste.
  • the fourth power is less than the second power, to better preventing dry burning.
  • the present embodiment is similar to Embodiment 1 in steps, except that: before acquiring a time interval between starting work this time and stopping work last time, the present embodiment further includes the following steps.
  • a temperature sensor which is connected to the controller may be arranged on the electronic cigarette.
  • the controller reads a temperature signal on the temperature sensor to acquire an environment temperature around the electronic cigarette, that is, the temperature of the user environment.
  • the controller adjusts the first preset time interval and the second preset time interval according to the environment temperature; thus, a good user experience can be obtained in areas at different temperatures.
  • the first preset time interval and the second preset time interval are directly proportional to the environment temperature
  • the first power and the second power are inversely proportional to the environment temperature. That is to say, the higher the environment temperature, the longer the first preset time interval and the second preset time interval, the lower the first power and the second power, which can better prevent mouth burning.
