     Referring to  FIG.  3   , it shows a flowchart of an electronic cigarette control method according to an embodiment of the present invention. In this embodiment, the electronic cigarette control method is used in the electronic cigarette shown in  FIG.  1    as an example. As shown in  FIG.  3   , the electronic cigarette control method may include: 
     Step  301 : acquiring the characteristic parameter of the atomizer of the electronic cigarette. 
     After the atomizer is connected to the battery device of the electronic cigarette, the electronic cigarette can acquire the characteristic parameter of the atomizer. 
     In the embodiments of the present invention, the characteristic parameter of an atomizer may include at least one of: the atomizer type, the liquid inlet amount of the atomizer, the air inlet amount of the atomizer, the resistance type of the heating element of the atomizer, and the resistance value of the heating element of the atomizer. The heating element of the atomizer may include, but is not limited to, any one of a heating sheet, a heating tube, and a resistance wire. 
     As a possible implementation manner, taking the characteristic parameter including the resistance type and the resistance value of the heating element of the atomizer as an example, the resistance type of the heating element of the atomizer includes: the resistivity of the heating element of the atomizer, the conductivity of the heating element of the atomizer, etc. For different characteristic parameters, the method of acquiring characteristic parameter is different. 
     When acquiring the characteristic parameter of the heating element of the atomizer of the electronic cigarette, the electronic cigarette can identify the resistance type of the heating element of the atomizer, and measure the resistance value of the heating element of the atomizer. 
     For example, the electronic cigarette can be provided with a current detection amplifier, which can measure the electric current and the voltage across the heating element of the atomizer. Optionally, the electronic cigarette can be provided with a current sensor and a voltage sensor, wherein the current sensor is used to measure the electric current across the heating element of the atomizer, and the voltage sensor is used to measure the voltage across the heating element of the atomizer. The above-mentioned measuring components (that is, the current detection amplifier or the current sensor and the voltage sensor) send the measuring results to the MCU (microcontroller unit). The MCU can calculate the resistance value of the heating element of the atomizer using the electric current and the voltage across the heating element of the atomizer. 
     When identifying the resistance type of the heating element of the atomizer, the electronic cigarette can firstly measure the resistivity of the heating element of the atomizer, and then determine the resistance type of the heating element of the atomizer based on the measured resistivity according to the preset relationship between the resistivity and the resistance type. 
     For further example, a memory may be provided in the atomizer, and the memory may store the resistance type and the resistance value of the heating element of the atomizer, and the atomizer type, etc., wherein the resistance type may include the resistivity and the conductivity, etc. Taking the resistivity of the heating element of the atomizer as an example when acquiring the characteristic parameter, after the atomizer is connected to the battery device of the electronic cigarette, the MCU of the electronic cigarette can read the resistivity of the heating element of the atomizer stored in the memory of the atomizer. 
     As another possible implementation manner, taking the characteristic parameter including the atomizer type and a first parameter as an example, wherein the first parameter includes but is not limited to at least one of: the liquid inlet amount of the atomizer, the air inlet amount of the atomizer, the resistance type of the heating element of the atomizer, and the resistance value of the heating element of the atomizer. After the user connects the atomizer to the battery device of the electronic cigarette, the user can manually input the atomizer type to the electronic cigarette and then query the first parameter according to the relationship between the atomizer type and the first parameter. 
     Referring to  FIG.  4   , it is a schematic structural diagram of a display screen of the electronic cigarette and the keys according to an embodiment of the present invention. The display screen  401  can display the atomizer type. The bottom of the display screen  401  includes at least one physical key, which is shown in  FIG.  4    as a key  402  ([OK] key), a key  403  ([+] key), and a key  404  ([−] key). 
     After the atomizer is connected to the battery device of the electronic cigarette, the MCU, when getting this connection signal, controls the display screen  401  to display an interface for selecting the atomizer type. The interface displays various optional atomizer types. The user can use [+] Key (key  403 ) or [-] key (key  404 ) to select the correct atomizer type, and use the [OK] key (key  402 ) to send the correct atomizer type to the MCU. The MCU can query the parameters corresponding to the correct atomizer type, such as the liquid inlet amount of the atomizer, the air inlet amount of the atomizer, the resistance type of the heating element of the atomizer, and the resistance value of the heating element of the atomizer according to a pre-stored relationship, wherein the pre-stored relationship between the atomizer type and the parameters such as the liquid inlet amount of the atomizer, the air inlet amount of the atomizer, the resistance type of the heating element of the atomizer, and the resistance value of the heating element of the atomizer can be stored in the MCU of the electronic cigarette in the form of a table. 
     Step  302 : determining the first output power corresponding to the characteristic parameter of the atomizer. 
     Optionally, the electronic cigarette may query a preset initial output power table stored in the MCU corresponding to the characteristic parameter of the atomizer according to the relationship between the characteristic parameter of the atomizer and the output power. Optionally, in the above-mentioned relationship, one characteristic parameter may correspond to one output power; or, multiple characteristic parameters may correspond to one output power. 
     For example, taking the characteristic parameter including the resistance type and the resistance value of the heating element of the atomizer as an example, when determining the first output power for outputting to the atomizer according to the characteristic parameter of the atomizer, the MCU determines the correlation groups between the resistance value of the heating element of the atomizer and the output power, so that the first output power corresponding to the resistance value of the heating element of the atomizer is queried and determined from the correlation groups. 
     The correlation groups may be stored in the form of a table in the MCU of the electronic cigarette. 
     For example, by taking the resistance value of the heating element of the atomizer as an example, please refer to Table 1, it shows a possible relationship. As shown in Table 1, in this relationship, the heating element of the atomizer is a notch coil type. When the resistance value of the heating element is 0.25Ω, the corresponding output power is 45W. When the resistance value of the heating element is 0.68Ω, the corresponding output power is 35W. When the resistance value of the heating element is 0.755Ω, the output power is 30W. The specific values of the resistance value and the output power are not limited in this embodiment. The relationship between the resistance value and the output power in this embodiment is only for illustration. The relationship between the resistance value and the output power in actual products can be obtained based on experimental data results of the R&amp;D personnel for different products.

     Step  303 : outputting electric energy to the atomizer with the first output power when a smoking signal is detected. 
     The MCU of the electronic cigarette instructs the power control circuit to control the battery device of the electronic cigarette to output electric energy to the heating element of the atomizer with the first output power, so that the e-liquid in the atomizer is atomized to generate smoke. 
     When the electronic cigarette performs step  301  and step  302 , the output power determined according to the characteristic parameter of the atomizer and the initial output power table is the first output power determined in step  302 . However, when step  301  and step  302  are not performed, the initial output power can be the preset output power in the electronic cigarette, or the output power of the atomizer when the electronic cigarette was last used, or the output power of the longest use time of the electronic cigarette, which is not limited in this embodiment. 
     In conclusion, in the electronic cigarette control method provided in this embodiment, by acquiring the characteristic parameter of the atomizer in the electronic cigarette, the output power of electric energy outputted to the atomizer is determined according to the relationship between the characteristic parameter of the atomizer and the output power, and then the determined output power of electric energy is outputted to the atomizer. That is, the electronic cigarette can output different power of electric energy to atomizers with different characteristic parameters, so that the battery device of the electronic cigarette can be adapted to atomizers with different specifications, to thereby improve the adaptation range of the electronic cigarette. 
     Referring to  FIG.  5   , it shows a flowchart of an electronic cigarette control method according to an embodiment of the present invention. In this embodiment, the electronic cigarette control method is used in the electronic cigarette shown in  FIG.  1    as an example. As shown in  FIG.  5   , the electronic cigarette control method may include: 
     Step  501 : acquiring the characteristic parameter of the atomizer of the electronic cigarette. 
     The electronic cigarette can detect whether an atomizer is connected to the battery device of the electronic cigarette through a detection device, wherein the detection device may be any one of a pressure sensor and a magnetic induction IC. 
     Referring to  FIG.  6   , it illustrates a connection diagram of an atomizer  603  and a battery device  602  according to an embodiment of the present invention. As shown in  FIG.  6   , the battery device  602  is provided with a pressure sensor  601 , and the pressure sensor  601  is provided at the connecting position between the battery device  602  and the atomizer  603 . After the atomizer  603  is connected with the battery device  602 , the atomizer  603  will generate a certain pressure on the pressure sensor  601 . When the battery device  602  detects whether the atomizer  603  is connected, the MCU in the battery device  602  can receive the sensing value detected by the pressure sensor  601 . When the sensing value detected by the pressure sensor  601  meets a preset condition, for example, if the sensing value is greater than a pressure threshold, the MCU of the electronic cigarette determines that an atomizer is connected to the electronic cigarette. 
     After the electronic cigarette detects that the atomizer is connected, the electronic cigarette starts to acquire the characteristic parameter of the atomizer. 
     The method of acquiring the characteristic parameter of the atomizer is similar to step  301 , which is not repeated in this embodiment. 
     For example, after the electronic cigarette identifies the resistance type of the heating element of the atomizer, the electronic cigarette displays the resistance type on the display screen; when an operation for resetting the resistance type is received, the electronic cigarette displays an interface for resetting the resistance type of the heating element of the atomizer; the electronic cigarette acquires the new resistance type that is reset in the interface for resetting the resistance type of the heating element of the atomizer; and the electronic cigarette replaces the resistance type of the heating element of the atomizer with the new resistance type. 
     Optionally, the electronic cigarette firstly acquires the resistivity of the heating element of the atomizer, and then compares the acquired resistivity of the heating element of the atomizer with a table of the resistance type of the heating element of the atomizer pre-stored in the MCU corresponding to the resistivity of the heating element of the atomizer, to thereby get the resistance type of the heating element of the atomizer corresponding to the acquired resistivity and feed it back to the MCU. The electronic cigarette displays the resistance type of the heating element of the atomizer on the display screen of the electronic cigarette. The user can judge whether the resistance type of the heating element of the atomizer displayed on the display screen is the same as the actual resistance type of the heating element of the atomizer. 
     Referring to  FIG.  7   , it is a schematic structural diagram of a display screen of the electronic cigarette with the keys according to an embodiment of the present invention. The display screen  701  can display the content to be displayed, such as the resistance type of the heating element of the atomizer, the atomizer type, and the like. The bottom of the display screen  701  includes at least a physical key, which is shown in  FIG.  7    as a key  702  (OK key), a key  703  ([+] key), a key  704  ([−] key), a key  705  ([ 1 ] key), and a key  706  ([ 2 ] key). 
     As a possible implementation manner, the electronic cigarette detects the resistance type of the heating element of the atomizer, and the electronic cigarette controls the display screen to display the resistance type of the heating element of the atomizer. The user can observe and judge whether the resistance type of the heating element of the atomizer displayed on the display screen is the same as the actual resistance type of the heating element of the atomizer connected to the electronic cigarette. If the user judges that the resistance types are the same, the user can manually press the [OK] key (i.e., key  702 ) to confirm that the electronic cigarette has identified the correct resistance type of the heating element of the atomizer. 
     As another possible implementation manner, the electronic cigarette detects the resistance type of the heating element of the atomizer, and the electronic cigarette controls the display screen to display the resistance type of the heating element of the atomizer. The user can observe and judge whether the resistance type of the heating element of the atomizer displayed on the display screen is the same as the actual resistance type of the heating element of the atomizer connected to the electronic cigarette. If the user judges that the resistance types are not the same, the user can manually press the [ 1 ] key (i.e., key  705 ). After the MCU gets this signal, it controls the display screen  701  to display an interface for selecting the resistance type of the heating element of the atomizer, wherein this interface displays various selectable resistance types. The user can select the correct resistance type of the heating element of the atomizer by using the [+] key (key  703 ) or the [−] key (key  704 ), and the correct resistance type of the heating element of the atomizer is fed back to the MCU through the [OK] key (key  702 ). 
     For example, assuming that the resistance type of the heating element of the atomizer detected by the electronic cigarette is a Notch Coil type. If the user observes and judges that the resistance type of the heating element of the atomizer displayed on the display screen is not the same as the actual resistance type of the heating element of the atomizer, then the user can press the [ 1 ] key, the display screen enters an interface for selecting the resistance type of the heating element of the atomizer, and the user can select the resistance type of the heating element of the atomizer by manually pressing the [+], [−] keys, and then press the [OK] key to get the correct resistance type of the heating element of the atomizer. 
     It should be noted that the above solution only takes the selection of the resistance type of the heating element of the atomizer through the keys as an example. In actual implementations, the resistance type or the atomizer type can also be selected by other solutions, for example, through a touch screen to select the resistance type of the heating element of the atomizer or the atomizer type, which is not limited in this embodiment. 
     Step  502 : determining whether the characteristic parameter of the atomizer is within a preset parameter range. 
     In a possible implementation manner, after an atomizer is connected to the battery device of the electronic cigarette and the electronic cigarette has acquired the characteristic parameter of the atomizer, the electronic cigarette can determine whether the characteristic parameter of the atomizer is within a preset parameter range, wherein the preset parameter range may be a parameter range of the characteristic parameter of the heating element of the atomizer supported by the battery device of the electronic cigarette; if the characteristic parameter of the atomizer is within the parameter range, then the electronic cigarette performs the above step of determining the first output power corresponding to the characteristic parameter of the atomizer. 
     Specifically, when detecting the characteristic parameter of the atomizer, the electronic cigarette compares the characteristic parameter of the atomizer with a first preset value and a second preset value of each characteristic parameter pre-stored in the MCU, wherein the first preset value is the maximum value of the preset parameter range, and the second preset value is the minimum value of the preset parameter range. When the characteristic parameter detected by the electronic cigarette is greater than the second preset value and smaller than the first preset value, the electronic cigarette can control the battery device to output electric energy to the atomizer with the first output power. 
     For example, taking the characteristic parameter including the resistance value of the heating element of the atomizer as an example, if the resistance value of the heating element of the atomizer that the electronic cigarette can match is in the range of 0.1 to 1, then the second preset value is the minimum value of 0.1 and the first preset value is the maximum value of 1 in the range. If the electronic cigarette detects that the resistance value of the heating element of the atomizer is 0.25, then the MCU compares the detected resistance value of the heating element of the atomizer with the pre-stored first and second preset values. The MCU determines that the detected resistance value of the heating element of the atomizer is greater than the second preset value of 0.1 and smaller than the first preset value of 1, and the MCU will then perform the step of determining the first output power corresponding to the characteristic parameter of the atomizer. 
     Optionally, when the characteristic parameter of the atomizer is greater than the preset parameter range, the electronic cigarette displays a first prompt message to indicate that the atomizer does not match the battery device of the electronic cigarette; when the characteristic parameter of the atomizer is smaller than the preset parameter range, the electronic cigarette displays a second prompt message to indicate that the atomizer is not installed correctly. 
     Specifically, when detecting the characteristic parameter of the atomizer, the electronic cigarette compares the characteristic parameter of the atomizer with a first preset value and a second preset value of each characteristic parameter pre-stored in the MCU, wherein the first preset value is the maximum value of the preset parameter range, and the second preset value is the minimum value of the preset parameter range. When the characteristic parameter detected by the electronic cigarette is greater than the first preset value, the MCU of the electronic cigarette can control the display screen to display a prompt message “the atomizer does not match the battery device of the electronic cigarette”; when the characteristic parameter detected by the electronic cigarette is less than the second preset value, the MCU of the electronic cigarette can control the display screen to display a prompt message “the atomizer is not installed correctly or may be damaged”. 
     In actual implementations, the specific values of the first preset value and the second preset value may be default values in the electronic cigarette or customized by the user, which is not limited in this embodiment. 
     For example, taking the characteristic parameter including the resistance value of the heating element of the atomizer as an example, if the resistance value of the heating element of the atomizer that the electronic cigarette can match is in the range of 0.1 to 1, then the second preset value is the minimum value of 0.1 and the first preset value is the maximum value of 1 in the range. 
     As a possible implementation situation, if the electronic cigarette detects that the resistance value of the heating element of the atomizer is 0.05, the MCU compares the detected resistance value of the heating element of the atomizer with the pre-stored first and second preset values, and the MCU determines that the detected resistance value of the heating element of the atomizer is smaller than the second preset value of 0.1, then the MCU controls the display screen to display the second prompt message “the atomizer is not installed correctly or may be damaged”. 
     As another possible implementation situation, if the electronic cigarette detects that the resistance value of the heating element of the atomizer is 1.1, the MCU compares the detected resistance value of the heating element of the atomizer with the pre-stored first and second preset values, and the MCU determines that the detected resistance value is greater than the first preset value of 1, then the MCU controls the display screen to display the first prompt message “the atomizer does not match the battery device of the electronic cigarette”. 
     Optionally, in a possible implementation situation, when the characteristic parameter of the atomizer is smaller than the preset parameter range, the electronic cigarette may also display the first prompt message to remind the user that the atomizer does not match the battery device of the electronic cigarette. For example, if the electronic cigarette detects that the resistance value of the heating element of the atomizer is 0.05, the MCU compares the detected resistance value of the heating element of the atomizer with the pre-stored range of resistance value (e.g., 0.1 to 1), and determines that the detected resistance value of the heating element of the atomizer is smaller than 0.1, then the MCU controls the display screen to display the first prompt message “the atomizer does not match the battery device of the electronic cigarette”. 
     The above only takes the electronic cigarette to control the display screen to display prompt message as an example. In actual implementations, the electronic cigarette can also issue alarms, for example, a reminding sound of “Di, Di, Di”, which is not limited in this embodiment. 
     Step  503 : determining the first output power corresponding to the characteristic parameter of the atomizer if the characteristic parameter of the atomizer is within the preset parameter range. 
     The method of determining the first output power corresponding to the characteristic parameter of the atomizer is similar to step  302 , which is not repeated in this embodiment. 
     Step  504 : outputting electric energy to the atomizer with the first output power when a smoking signal is detected. 
     The electronic cigarette determines the first output power through the MCU, and controls the atomizer in the electronic cigarette to generate smoke with the first output power, wherein the method of outputting the first output power to the atomizer is similar to step  303 , which is not repeated in this embodiment. 
     Step  505 : when an adjustment operation of adjusting the output power is received, acquiring the second output power in response to the adjustment operation. 
     Step  506 : outputting electric energy to the atomizer with the second output power. 
     Optionally, the user can manually adjust the output power. For example, taking  FIG.  6    as an example, when the user wants to increase the output power, the user can press the [+] key twice, and when the user wants to decrease the output power, the user can press the [−] key twice. If the electronic cigarette detects that the [+] key is pressed twice, the MCU controls the display screen to display a prompt message of whether to increase the output power. After the user presses the [OK] key, then each time the [+] key is pressed, the MCU controls the display screen to display that the output power is increased by one unit (e.g., 1 W). When the displayed value of output power reaches the second output power desired by the user, the user presses the [OK] key, and the MCU controls the power control circuit to output power to the atomizer with the second output power. Correspondingly, if the electronic cigarette detects that the [−] key is pressed twice, the MCU controls the display screen to display a prompt message of whether to decrease the output power. After the user presses the [OK] key, then each time the [−] key is pressed, the MCU controls the display screen to display that the output power is decreased by one unit (e.g., 1 W). When the displayed value of output power reaches the second output power desired by the user, the user presses the [OK] key, and the MCU controls the power control circuit to output power to the atomizer with the second output power. 
     For example, when the electronic cigarette detects that the resistance value of the heating element of a notch coil type atomizer is 0.75Ω, the MCU determines, through query, that the first output power of the atomizer should be 30W according to the relationship between the resistance value of the heating element of the atomizer and the output power. Then, 30W, as the first output power, is outputted to the atomizer. 
     As a possible implementation manner, when the user presses the [+] key twice, the MCU receives the input signal, determines that the user wants to increase the output power of the atomizer, and controls the display screen to display the prompt message “increase the output power?”. If the user presses the [OK] key, the MCU determines to start increasing the output power. When the user presses the [+] key once, the MCU increases the output power by 1 W, and controls the display screen to display the increased output power. After the second output power reaches 35 W desired by the user, the user presses the [OK] key, and the MCU controls the power control circuit to output power to the atomizer with the second output power of 35 W. 
     As another possible implementation manner, when the user presses the [−] key twice, the MCU receives the input signal, determines that the user wants to decrease the output power of the atomizer, and controls the display screen to display the prompt message “decrease the output power?”. If the user presses the [OK] key, the MCU determines to start decreasing the output power. When the user presses the [−] key once, the MCU decreases the output power by 1 W, and controls the display screen to display the decreased output power. After the second output power reaches 25 W desired by the user, the user presses the [OK] key, and the MCU controls the power control circuit to output power to the atomizer with the second output power of 25 W. 
     The above only takes controlling the output power of the electronic cigarette through the keys as an example. In actual implementations, the output power of the electronic cigarette can also be selected by other solutions, for example, the output power required by the user can be inputted through a touch screen, or can also be customized by the user through the APP in the mobile terminal and then sent to the electronic cigarette, which is not limited in this embodiment. 
     Optionally, the electronic cigarette sets the second output power as the new first output power corresponding to the characteristic parameter of the atomizer. 
     After the user selects a suitable second output power, the MCU sets the second output power as the new first output power corresponding to the characteristic parameter of the atomizer. When the user uses an atomizer with the same characteristic parameter to connect to the battery device of the electronic cigarette, the electronic cigarette will output electric energy to the atomizer with the new first output power. 
     For example, assuming that the first output power of a notch coil type atomizer with a resistance value of the heating element being 0.75Ω is 30W, the second output power after adjustment by the user is 35W. The MCU replaces the first output power of 30W corresponding to the resistance value 0.75Ω of the heating element of the atomizer with the second output power 35W as the new first output power, and stores the new first output power of 35W in the MCU. When the user uses a notch coil type atomizer with a resistance value of the heating element being 0.75Ω to connect to the electronic cigarette, the electronic cigarette will output electric energy to the atomizer with the new first output power of 35W. 
     In another possible implementation manner, the electronic cigarette can count the adjustment operations of the output power of the atomizer corresponding to the characteristic parameter within a preset period of time, and set the new first output power corresponding to the characteristic parameter of the atomizer according to the counted adjustment operations of the output power. The preset time period may be a preset length of time period before the current time, such as one month or one year before the current time. 
     Specifically, among the second output powers corresponding to the output power adjustment operations of the atomizer according to the characteristic parameter, the output power being adjusted most times in a preset period of time can be set as the new first output power. Optionally, among the second output powers corresponding to the output power adjustment operations of the atomizer according to the characteristic parameter, the output power with the longest use time in a preset period of time can be set as the new first output power. 
     As a possible implementation manner, the user adjusts the output power of an atomizer with a certain characteristic parameter several times, the MCU records each second output power as being adjusted by each adjustment, counts the number of times each second output power is adjusted, and sets the second output power adjusted by the user with the most times as the new first output power of the atomizer corresponding to the characteristic parameter. 
     For example, if the user uses a Notch Coil type atomizer with a resistance value 0.75Ω, of the heating element, the first output power is 30W, the MCU detects that the user adjusts the output power to 34W four times and the user adjusts the output power to 36W six times, then the MCU selects the second output power 36W being adjusted by the user with the most times as the new first output power of the atomizer, and it is stored in the MCU. When the user uses a notch coil type atomizer with a resistance value of the heating element being 0.75Ω to connect to the electronic cigarette, the electronic cigarette will output electric energy to the atomizer with the new first output power of 36W. 
     As another possible implementation manner, the user adjusts the output power of an atomizer with a certain characteristic parameter several times, the MCU records each second output power as being adjusted by each adjustment and the use time of each second output power, and sets the second output power with the longest use time by the user as the new first output power of the atomizer corresponding to the characteristic parameter. 
     For example, if the user uses a Notch Coil type atomizer with a resistance value 0.75Ω, of the heating element, the first output power is 30W, the MCU detects that the total use time is 4 minutes when the output power is adjusted to 34W and the total use time is 6 hours when the output power is adjusted to 36W, then the MCU selects the output power 36W with the longest use time by the user as the new first output power of the Notch Coil type atomizer with a resistance value 0.75Ω of the heating element. When the user uses a notch coil type atomizer with a resistance value of the heating element being 0.75Ω to connect to the electronic cigarette, the electronic cigarette will output electric energy to the atomizer with the new first output power of 36W. 
     In conclusion, in the electronic cigarette control method provided in this embodiment, by acquiring the characteristic parameter of the atomizer in the electronic cigarette, the output power of electric energy outputted to the atomizer is determined according to the relationship between the characteristic parameter of the atomizer and the output power, and then the determined output power of electric energy is outputted to the atomizer. That is, the electronic cigarette can output different power of electric energy to atomizers with different characteristic parameters, so that the battery device of the electronic cigarette can be adapted to atomizers with different specifications, to thereby improve the adaptation range of the electronic cigarette. 
     Further, in the electronic cigarette control method provided in this embodiment, the user can adjust the output power autonomously during the smoking of the electronic cigarette by the user. When the user installs the same atomizer again, the electronic cigarette will the new first output power, so as to provide appropriate output power based on the user&#39;s usage habits. 
       FIG.  8    is a flowchart of an electronic cigarette control method according to an embodiment of the present invention. In  FIG.  8   , after the electronic cigarette is turned on, the electronic cigarette starts to initialize. The pressure sensor of the electronic cigarette detects whether an atomizer is connected. When the pressure sensor of the electronic cigarette detects the change of pressure, the electronic cigarette determines that the user has installed the atomizer. By detecting the characteristic parameter of the atomizer, the electronic cigarette automatically identifies the resistance type of the heating element of the atomizer, and the user judges whether the resistance type of the heating element of the atomizer is correctly identified. If the resistance type of the heating element of the atomizer is correctly identified, the electronic cigarette automatically determines the first output power according to the resistance type of the heating element of the atomizer. If the resistance type of the heating element of the atomizer is incorrectly identified, the user can manually input the resistance type of the heating element of the atomizer, and the electronic cigarette automatically determines the first output power according to the resistance type of the heating element of the atomizer. Then, the first output power and related parameters of the atomizer are refreshed and displayed on the main display interface.

When the output power is required to be adjusted, the user increases or decreases the output power through an input module to the second output power, and after adjustment, the first output power is replaced by the second output power and stored in the electronic cigarette as the new first output power. When an atomizer of the same type is connected to the electronic cigarette next time, the new first output power is outputted to the atomizer. Then, the first output power and related parameters of the atomizer are refreshed and displayed on the main display interface.
