[0006] The resistance control silica gel is provided with a resistance air inlet hole and a resistance control diaphragm; the resistance control diaphragm can change the opening size according to the air pressure difference between the inside and outside formed by the suction force.

[0007] The resistance control diaphragm is a sheet-shaped silica gel, and a notch is arranged on the sheet-shaped silica gel; when there is no air pressure difference or the air pressure difference is very small between the inside and outside, the notch is in a closed state, when the air pressure difference is large, the notch is opened, and when the air pressure difference continues to increase, the opening degree of the notch increases.

[0008] When the suction force is small, the notch of the resistance control silica gel is in a closed state, the airflow sensor outputs a low signal, and the MCU on the PCBA board receives the signal of the airflow sensor and outputs low power accordingly;

[0020] Such as Figs. 1 to 7The electronic cigarette shown comprises a base 1, a PCBA board 3 and an airflow sensor; the base 1 is provided with a base air inlet hole 11. The base air inlet hole 11 is provided with a suction resistance control silica gel 2, the suction resistance control silica gel 2 is provided with a suction resistance air inlet hole 21 and a suction resistance control diaphragm 22; the suction resistance control diaphragm 22 can change the opening size according to the air pressure difference between the inside and outside formed by the suction force. The suction resistance control diaphragm 22 is a sheet-shaped silica gel; and a notch 23 is arranged on the sheet-shaped silica gel; the notch 23 is in a closed state when there is no air pressure difference or the air pressure difference is very small between the inside and outside, and the notch 23 opens when the air pressure difference is large, and the opening degree of the notch 23 increases when the air pressure difference continues to increase.

[0021] The airflow sensor is further arranged on the airflow channel of the electronic cigarette; the airflow sensor converts the airflow size into an electrical signal size and inputs the electrical signal size into the MCU of the PCBA board 3; the MCU controls the output power size of the electronic cigarette atomization core assembly according to the input airflow sensor signal size.

[0022] When the user inhales, the diaphragm notch 23 of the suction resistance control silica gel 2 does not open and only the suction resistance air inlet hole 21 of the suction resistance control silica gel 2 inhales in the case of small suction force; meanwhile, the MCU on the PCBA board 3 controls the corresponding low-power output according to the signal received by the airflow sensor to match a large suction resistance (small air inlet on the silica gel); at this time, the user can inhale by mouth.

[0023] In the case of large suction force, the diaphragm notch 23 of the suction resistance control silica gel 2 opens partially under the action of the suction force, the air inlet of the electronic cigarette is the air inlet of the suction resistance air inlet hole 21 plus the air inlet of the diaphragm notch 23 partially opened, and meanwhile, the MCU on the PCBA board 3 controls the corresponding medium-power output according to the signal received by the airflow sensor to match a medium suction resistance (medium air inlet); at this time, the user can perform small lung suction.

[0024] In the case of very large suction force, the diaphragm notch 23 of the suction resistance control silica gel 2 opens completely under the action of the suction force, the air inlet of the electronic cigarette is the air inlet of the fixed suction resistance air inlet hole 21 plus the air inlet of the diaphragm notch 23 completely opened, and meanwhile, the MCU on the PCBA board 3 controls the corresponding high-power output according to the signal received by the airflow sensor to match a small suction resistance (large air inlet); at this time, the user can perform deep lung suction.
