Optionally, at least two of the main control board 140, the switch board 150 and the control circuit 160 are integrated into one piece. For example, in some embodiments, the main control board 140, the switch board 150 and the control circuit 160 are integrated in a same PCB (also referred to as circuit board); in some embodiments, the main control board 140 and the switch board 150 are integrated on a same PCB, the control circuit 160 is separately provided; in some embodiments, the main control board 140 and the control circuit 160 are integrated on a same PCB, and the switch board 150 is separately provided; in some embodiments, the switch board 150 and the control circuit 160 are integrated on a same PCB, and the main control board 140 is separately provided.

Further, a part of the operation part 310 is exposed outside the housing 210, in order to facilitate a user operation. In an exemplary embodiment, the connection part 320 is a flexible structure. For example, a material of the connection part 320 is silicone; of course, the material of the connection part 320 can also be other flexible materials. It can be understood that the structure of the mechanical switch 300 is not limited to the structure of the mechanical switch 300 shown in FIG. 6. For example, the mechanical switch 300 only includes the operation part 310, which is directly matched with the touch control part 151 in the concave-convex manner, or in other matching manners.
In an embodiment of the disclosure, the trigger information includes a first duration of the mechanical switch 300 being triggered and/or a number of times of the mechanical switch 300 being triggered in a preset time period, of course, the trigger information is not limited to this, but can also include other information. Taking the mechanical switch 300 as the push switch, in the embodiment of the disclosure, the mechanical switch 300 is triggered once, that is, the user presses the mechanical switch once. A value of the preset time period is small, and the number of times of the mechanical switch 300 is triggered in the preset time period can be regarded as a continuous operation of the mechanical switch 300. The value of the preset time period can be set as required. For example, the preset time period is 5 seconds; of course, the preset time period can also be set to other numerical values.
The first electrical connection part 130 is electrically connected with the control circuit 160. In addition, as shown in FIG. 7, in an embodiment of the disclosure, the main control board 140 is electrically connected with the battery 120, the switch board 150 and the control circuit 160 individually. In an embodiment of the disclosure, the main control board 140 is capable of controlling the battery rod 100 to be turned on or be turned off according to the trigger information, and after the battery rod 100 is turned on, the main control board 140 is capable of controlling the control circuit 160 whether output a current to the first electrical connection part 130 or not according to the trigger information, and a magnitude and/or a second duration of the current outputted from the control circuit 160, and is further capable of controlling a voltage output rank of the atomizer.
For example, in some embodiments, the trigger information includes the first duration of the mechanical switch 300 being triggered, when the first duration is greater than or equal to a first preset duration, the main control board 140 controls the main control board 140 to output a first current to the first electrical connection part 130, so that the atomizing head 200 performs a heating function, in other words, the mechanical switch 300 is pressed continuously (also referred to as the mechanical switch 300 is pressed for a long time), the main control board 140 controls the control circuit 160 to output the first current to the first electrical connection part 130, so that the atomizing head 200 performs the heating function. Optionally, the first current is an output current of a real-time voltage output rank of the atomizer. The atomizer of the embodiment can include multiple voltage output ranks. For example, the atomizer can include three voltage output ranks: 2.8V output voltage, 3.25V output voltage and 3.6V output voltage. The output currents of different voltage output ranks are different. When the atomizer is used, the atomizer can be set at one of the voltage output ranks to supply a power to the atomizing head 200 through the output current of the voltage output rank. A value of the first preset duration can be set as required. For example, the first preset duration can be 5 seconds or other numerical values.
Furthermore, if the mechanical switch 300 is switched to a non-triggered state, that is, the mechanical switch 300 is released, and the main control board 140 controls the control circuit 160 to stop outputting the first current to the first electrical connection part 130 during the process of the atomizing head 200 performing the heating function, so as to stop the heating function of the atomizing head 200. Optionally, when a second duration of the continuous output current of the control circuit 160 is greater than a second preset duration, the main control board 140 controls the control circuit 160 to stop outputting the first current to the first electrical connection part 130, so as to stop the heating function of the atomizing head 200, that is, after the heating of the atomizing head 200 exceeds a heating time, the heating of the atomizing head 200 is stopped. A value of the second preset duration can be set as required. For example, the second preset duration can be 8 seconds or other.
In some embodiments, the trigger information includes the number of times of the mechanical switch 300 being triggered in the preset time period. When the trigger information indicates that the number of times of the mechanical switch 300 being triggered in the preset time period is a first preset number, the main control board 140 controls the control circuit 160 to output a preheating current to the first electrical connection part 130, so that the atomizing head 200 performs a preheating function, that is, a number of times of continuously operates the mechanical switch 300 is the first preset number, the atomizing head 200 is preheated.

In this embodiment, the first preset number is greater than or equal to 2, and the first preset number can be set as required. For example, the first preset number can be 2 or other. Furthermore, if the mechanical switch 300 is triggered once (or other times) when the atomizing head 200 performs the preheating function, the main control board 140 controls the control circuit 160 to stop outputting the preheating current to the first electrical connection part 130, so as to stop the preheating function of the atomizing head 200.
In some embodiments, the trigger information includes the number of times of the mechanical switch 300 being triggered in the preset time period. When the trigger information indicates that the number of times of the mechanical switch 300 being triggered in the preset time period is a second preset number, the main control board 140 switches a current voltage output rank to a next voltage output rank. In this embodiment, the second preset number is greater than or equal to 2, and the second preset number can be set according to needs. For example, the second preset number can be 3 times or other. In an exemplary embodiment, a sequence of voltage output rank switching can be 2.8V output voltage→3.25V output voltage→3.6V output voltage, and cycle in turn.
In some embodiments, the trigger information includes the number of times of the mechanical switch 300 being triggered in the preset time period. When the trigger information indicates that the number of times of the mechanical switch 300 being triggered in the preset time period is a third preset number, the main control board 140 controls the battery rod 100 to be turned on or be turned off, and controls the voltage output rank of the atomizer to return to a voltage output rank before the battery rod 100 was turned off. That is to say, when the battery rod 100 is turned off and a number of times of continuous operation of the mechanical switch 300 is the third preset number, the battery rod 100 is turned on, and the voltage output rank of the atomizer is returned to the voltage output rank before the battery rod 100 is turned off; when the battery rod 100 is turned on and the number of times of continuous operation of the mechanical switch 300 is the third preset number, the battery rod 100 is turned off. In this embodiment, the third preset number is greater than or equal to 2, and the third preset number can be set according to the needs, for example, the third preset number can be 5 times or other.
It can be understood that the first preset number, the second preset number and the third preset number are different.

Optionally, when the first duration is greater than or equal to the first preset duration, the main control board 140 controls the rank indicator light 181 corresponding to the first current to change from a first brightness value to a second brightness value, and keeps it on a constant state. The first brightness value is less than the second brightness value, that is, the rank indicator light 181 corresponding to the first current is gradually brighter.
Furthermore, during the process of the heating function of the atomizing head 200, if the mechanical switch 300 is released, the main control board 140 turns off the rank indicator light 181 corresponding to the first current. Optionally, during the heating function of the atomizing head 200, if the mechanical switch 300 is released, the main control board 140 controls the rank indicator light 181 corresponding to the first current to gradually change from a constant on state to an off state, thereby reminding the user that the heating process of the atomizing head 200 is turned off.
Furthermore, when the second duration of the continuous output current of the control circuit 160 is greater than the second preset time, the main control board 140 controls the rank indicator light 181 corresponding to the first current to flash for a fourth preset number, that is, after the heating time-out, the rank indicator light 181 corresponding to the first current flashes for the fourth preset number, thereby reminding the user of the heating timeout of the atomizing head 200. In this embodiment, the fourth preset number can be set according to the needs. For example, the fourth preset number can be 8 times or other.
In some embodiments, the preheating current is the current corresponding to one of the charging voltage ranks. When the trigger information indicates that the number of times of the mechanical switch 300 being triggered in the preset time period is the first preset number, the main control board 140 turns on a rank indicator light 181 corresponding to the preheating current, thus reminding the user that the atomizing head 200 enters the preheating process. Optionally, the main control board 140 turns on the rank indicator light 181 corresponding to the preheating current, which is normally on for 6 seconds or other duration.
In some embodiments, if the mechanical switch 300 is triggered once (or other times) in the process of the atomizing head 200 performing the preheating function, the main control board 140 turns off the rank indicator light 181 corresponding to the preheating current, so as to remind the user that the atomizing head 200 exits the preheating process.
