[0069] In the above embodiments, a cross sectional area of the first clamping block gradually decreases in a direction towards a top. By using this structure, it is convenient to pass the first clamping block 112 through the second through hole 281.

[0070] In the above embodiments, in order to make the structure of the electronic cigarette 100 in this embodiment be reasonably distributed, the main unit 1 is provided with a first installation cavity 113 for accommodating the cartridge main body 22 and an avoidance notch 114 positioned on one side of the first installation cavity 113 for the installation main body 23. The first installation cavity 113 is connected to the avoidance notch 114. The hook 110 is positioned on the avoidance notch 114. A portion of the first conductive member 131 is positioned into the first installation cavity 113. The liquid bottle 3 is detachably arranged on the installation main body 23, that is, the liquid bottle 3 and the cartridge main body 22 are arranged horizontally side by side. The main unit 1 is provided with a first clamping groove 116 on a side wall of the first installation cavity 113. An outer side wall of the cartridge main body 22 is provided with a second clamping block 221 adapted to the first clamping groove 116. The second clamping block 221 is positioned into the first clamping groove 116 when the cartridge when the cartridge assembly is assembled onto the main unit. By configuring the cooperation of the first clamping groove 116 and the second clamping groove 222, the cartridge assembly 2 can be assembled onto the main unit 1 more stably.

[0071] In another embodiment, the hook 110 can be arranged on the cartridge assembly 2, and the movable block 28 and the elastic member 29 are arranged on the main unit 1. Or, the cartridge main body 22 can also be detachably connected to the main unit 1 through snaps or magnets.

[0072] In the above embodiments, the main unit 1 is provided with a limiting bracket 12, a battery 14, a microphone 132 for detecting airflow, and an airflow channel 120 connected to the atomizing core 25. The circuit board 13 is arranged on the limiting bracket 12, the circuit board 13 is electrically connected to the battery 14 and the microphone 132 respectively, the first conductive memberl31 passes through the limiting bracket 12 and then is positioned into the first installation cavity 113, and the circuit board 13 is positioned above the battery 14. In this way, when the user sucks through the mouthpiece 21, the internal microphone 132 detects the airflow difference and feeds back an electrical signal to the circuit board 13. When the circuit board 13 receives the electrical signal from the circuit board 13, it drives the atomizing core 25 to heat up through the first conductive member 131 and the second conductive member 223 to atomize the tobacco liquid in the liquid storage cavity 220 to form smoke. The smoke is sucked by the user through the mouthpiece 21 along with the flow of air to realize the function of the electronic cigarette 100.

[0073] The above description only describes embodiments of the present invention, and is not intended to limit the present invention; various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
