The main body 10 of electronic cigarette includes a cartridge 2. The cartridge 2 is internally equipped with a first liquid cavity 20. The cartridge 2 is provided with a liquid inlet hole 201 communicated with the first liquid cavity 20. The liquid bottle 3 is internally provided with a second liquid cavity 30, and the liquid bottle 3 is provided with a liquid outlet channel 34 communicated with the second liquid cavity 30. A liquid injection control component is provided on the liquid bottle 3. When the liquid bottle 3 is installed on the main body 10 of electronic cigarette, the liquid outlet channel 34 is in communication with the liquid inlet hole 201. The liquid injection control component is configured for blocking the liquid outlet channel 34 in an initial state, and the liquid injection control component is configured for communicating the liquid outlet channel 34 under external force. The liquid injection control component is also configured for restoring to the initial state when the external force is removed.
In this embodiment, the liquid injection control component is configured on the liquid bottle 3, so that after the tobacco liquid in the first liquid cavity 20 is used up, a user can install the liquid bottle 3 on the main body 10 of electronic cigarette to allow the liquid inlet hole 201 and the liquid outlet channel 34 to be in communication. Moreover, by operating the liquid injection control component, the liquid outlet channel 34 can be in communication, so that the tobacco liquid in the second liquid cavity 30 enters the first liquid cavity 20 through the liquid outlet channel 34 and the liquid inlet hole 201, thereby adding the tobacco liquid to the cartridge 2 to improve the usage time of the main body 10 of electronic cigarette and a total number of user's puffs. After the user cancels the operation of the liquid injection control component, the liquid injection control component returns to an initial state, that is, to block the liquid outlet channel 34, thereby achieving controllable liquid injection, preventing the liquid outlet channel 34 from being communicated with the liquid inlet hole 201 all the time, preventing excessive tobacco liquid in the first liquid cavity 20, effectively reducing the probability of excessive tobacco liquid being consumed by the user, and improving user experience.
In one embodiment, the main body 10 of electronic cigarette further includes a main unit 1, and the cartridge 2 is detachably mounted on the main unit 1. When the cartridge 2 is assembled onto the main unit 1, the cartridge 2 is electrically connected to the main unit 1.

Alternatively, the liquid bottle 3 can be installed on the main unit 1, which can also achieve the communication between the liquid outlet channel 34 and the liquid inlet hole 201 when the liquid bottle 3 is installed on the main body 10 of electronic cigarette.
In one embodiment, liquid absorbing cotton 27 for adsorbing tobacco liquid is provided in the first liquid cavity 20, so that tobacco liquid can be adsorbed by the liquid absorbing cotton 27, and the tobacco liquid will not leak out from the liquid inlet hole 201. A first sealing ring 22 is arranged on the liquid inlet hole 201. When the liquid outlet channel 34 is in communication with the liquid inlet hole 201, the first sealing ring 22 abuts against the liquid bottle 3 to prevent tobacco liquid from leaking out between the liquid outlet channel 34 and the liquid inlet hole 201.
In one embodiment, liquid passing cotton 23 is provided inside the liquid inlet hole 201, and the material of the liquid passing cotton 23 is the same as that of the liquid absorbing cotton 27. By using the liquid passing cotton 23, the leakage of tobacco liquid can be further prevented, and by using the liquid passing cotton 23, the speed of liquid injection can be reduced when the liquid bottle 3 injects the cartridge 2 with tobacco liquid.

The connecting member 362 is at least partially placed in the liquid outlet channel 34, and the abutting block 363 is in contact with the operating member 35. A contact surface between the operating member 35 and the abutting block 363 is an inclined surface or a curved surface. When the operating member 35 is pressed, the stop block 361 moves in a direction away from the liquid outlet opening 341 to open the liquid outlet opening 341. When the stop block 361 is in the initial state, the stop block 361 covers the liquid outlet opening 341. By using the inclined surface or the curved surface, when the operating member 35 is pressed, the abutting block 363 can be pushed to move, that is, the connecting member 362 drives the stop block 361 to move in the direction away from the liquid outlet opening 341 to open the liquid outlet channel 34, so that the tobacco liquid in the second liquid cavity 30 can be added to the first liquid cavity 20 through the liquid outlet channel 34 and the liquid inlet hole 201. Moreover, when the pressure is withdrawn, by utilizing the restoration of the first elastic member 37, the abutting block 363 is pushed to move. By utilizing the connecting member 362 to drive the stop block 361 to block the liquid outlet channel 34, the liquid outlet channel 34 can be prevented from continuing to discharge liquid, thereby achieving controllable liquid injection. Moreover, when the abutting block 363 is restored, the operating member 35 can be pushed to return to an initial position.
In one embodiment, the stop block 361 is positioned above the liquid outlet opening 341, and a top portion of the first installation cavity 301 is provided with a first avoidance hole 302 communicated with the liquid outlet channel 34.

By using the second sealing ring 360, the tobacco liquid can be prevented from entering the first installation cavity 301 from a position between the connecting member 362 and the annular enclosure wall 331, thus preventing liquid leakage. By using the third sealing ring 330 to seal the liquid outlet opening 341, preventing the leakage of tobacco liquid from the liquid outlet channel 34 when the liquid bottle 3 does not inject the cartridge 2 with tobacco liquid, thus providing a sealing effect.
In one embodiment, the liquid injection control component further includes a second elastic member 39 disposed within the first installation cavity 301. The second elastic member 39 is positioned between a side wall of the first installation cavity 301 and the operating member 35. The second elastic member 39 is compressed when the operating member 35 is pressed, and the second elastic member 39 pushes the operating member 35 back to an initial position when the operating member 35 is released. By utilizing the second elastic member 39 and combining a restoration force of the first elastic member 37, the operating member 35 can be restored to the initial position more quickly, and the stop block 361 can be restore to an initial state more quickly.
In the above embodiment, in order to facilitate the production and manufacturing of the liquid bottle 3, the liquid bottle 3 includes a first outer shell 31, an intermediate shell 33, and a first bottom shell 38.
