Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to an electronic cigarette capable of automatically adjusting power and inhalation resistance. Background Art

[0002] At present, the electronic cigarettes with adjustable power and inhalation resistance on the market adjust the power output by manually adjusting the power button, and at the same time, the air adjustment pull switch is pulled to adjust the inhalation resistance and power. For consumers, the operation is cumbersome; moreover, if you have no experience in using such electronic cigarettes with adjustable power and inhalation resistance, the taste of the combination will be very poor. Summary of the invention

[0003] The technical problem solved by the present invention is to provide an electronic cigarette that can automatically adjust power and inhalation resistance; the problems existing in the power and inhalation resistance adjustment of the above-mentioned existing electronic cigarettes can be solved.

[0004] The technical solution of the present invention to solve the above technical problems is:

[0005] The electronic cigarette includes a base and a PCBA board. The base is provided with a base air inlet; the base air inlet is provided with a suction resistance control silicone, and the suction resistance control silicone can control the opening size of the base air inlet according to the suction force; the electronic cigarette is also provided with an airflow sensor on the airflow channel; the airflow sensor converts the airflow size into an electrical signal size and inputs it into the MCU (Microcontroller Unit) of the PCBA board; the MCU controls the output power size of the atomization core assembly according to the input airflow sensor signal size.

[0006] The resistance-suction control silica gel is provided with a resistance-suction inlet hole and a resistance-suction control membrane flap; the resistance-suction control membrane flap can change the opening size according to the air pressure difference between the inner and outer sides formed by the suction force.

[0007] The suction resistance control membrane petal is a thin sheet of silicone; and an incision is set on the thin sheet of silicone; the incision is in a closed state when there is no air pressure difference between the inner and outer sides or the pressure difference is very small, and the incision is opened when the air pressure difference is large, and the opening degree of the incision increases as the air pressure difference continues to increase.

[0008] When the suction force is small, the cutout of the suction resistance control silicone is in a closed state, the airflow sensor outputs a low signal, and the MCU on the PCBA board receives the signal from the airflow sensor and outputs a corresponding low power;

[0009] When the suction force is large, the cutout of the suction resistance control silicone opens partially under the action of the suction force, the airflow sensor outputs a medium signal, and the MCU on the PCBA board receives the signal of the airflow sensor and outputs a corresponding medium power;

[0010] When the suction force is very strong, the cutouts of the suction resistance control silicone are fully opened under the action of the suction force, the airflow sensor outputs a high signal, and the MCU on the PCBA board receives the signal from the airflow sensor and outputs a corresponding high power.

[0011] The present invention automatically adjusts the suction resistance and power through the suction resistance control silica gel and the airflow sensor; the power adjustment button and the suction resistance pull switch are eliminated, simplifying the structure. At the same time, the power and suction resistance are automatically adjusted through the structure of the automatic power adjustment chip and the automatic air inlet hole, which solves the trouble of users repeatedly manually adjusting the power and suction resistance, and is convenient for the majority of users; it can also ensure a good taste experience.

[0020] like Figures 1 to 7 As shown, the electronic cigarette of the present invention includes a base 1, a PCBA board 3 and an airflow sensor; the base 1 is provided with a base air inlet 11. The base air inlet 11 is provided with a suction resistance control silicone 2, and the suction resistance control silicone 2 is provided with a suction resistance air inlet 21 and a suction resistance control membrane flap 22; the suction resistance control membrane flap 22 can change the opening size according to the air pressure difference between the inner and outer sides formed by the suction force. The suction resistance control membrane flap 22 is a thin sheet of silicone; and a cutout 23 is provided on the thin sheet of silicone; the cutout 23 is in a closed state when there is no air pressure difference between the inner and outer sides or the pressure difference is very small, and the cutout 23 is opened when the air pressure difference is large, and the opening degree of the cutout 23 increases as the air pressure difference continues to increase.

[0021] An airflow sensor is also provided on the airflow channel of the electronic cigarette; the airflow sensor converts the airflow size into an electrical signal size and inputs it into the MCU of the PCBA board 3; the MCU controls the output power size of the electronic cigarette atomization core component according to the input airflow sensor signal size.

[0022] When the user is inhaling, the membrane flap incision 23 of the suction resistance control silicone 2 is not opened when the suction force is small, and only the suction resistance air inlet 21 of the suction resistance control silicone 2 takes in air; at the same time, the MCU on the PCBA board 3 controls the corresponding low-power output according to the signal received from the airflow sensor to match a larger suction resistance (small air intake on the silicone); at this time, the user can inhale through the mouth.

[0023] When the suction force is relatively large, the membrane flap cutout 23 of the suction resistance control silicone 2 is partially opened under the action of the suction force, and the air intake of the electronic cigarette is the air intake of the suction resistance air intake hole 21 plus the air intake of the partially opened membrane flap cutout 23. At the same time, the MCU on the PCBA board 3 controls the corresponding medium power output according to the signal received from the airflow sensor to match the medium suction resistance (medium air intake); at this time, the user can perform small lung inhalation.

[0024] When the suction force is very strong, the membrane flap cutout 23 of the suction resistance control silicone 2 is fully opened under the action of the suction force, and the air intake of the electronic cigarette is the fixed suction resistance air intake hole 21 air intake plus the air intake of the membrane flap cutout 23 fully opened. At the same time, the MCU on the PCBA board 3 controls the corresponding high-power output to match the small suction resistance (large air intake volume) according to the signal received from the airflow sensor; at this time, the user can perform deep lung inhalation.

[0025] The above electronic cigarette solution can be adapted to various types of electronic cigarettes and is not limited by other structures of the electronic cigarette.

[0026] The above embodiments are descriptions of specific implementation methods of the present invention, and are not limitations of the present invention; all equivalent modifications that can be obtained based on the above description should be within the protection scope of the present invention.
