[0037] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] Referring to the attached Figures 1-11 , an e-cigarette component with controllable oil injection in the embodiments of the present utility model.

[0039] The e-cigarette component with controllable oil injection includes an e-cigarette body 10 and an oil bottle 3 externally installed on the e-cigarette body 10. The e-cigarette body 10 includes a cartridge 2, a first oil chamber 20 is arranged in the cartridge 2, and an oil inlet hole 201 communicating with the first oil chamber 20 is formed on the cartridge 2. A second oil chamber 30 is arranged in the oil bottle 3, an oil outlet channel 34 communicating with the second oil chamber 30 is formed on the oil bottle 3, and an oil injection control component is arranged on the oil bottle 3. The oil outlet channel 34 communicates with the oil inlet hole 201 when the oil bottle 3 is installed on the e-cigarette body 10. The oil injection control component is configured to block the oil outlet channel 34 in the initial state, the oil injection control component is configured to conduct the oil outlet channel 34 under the action of an external force, and the oil injection control component is further configured to return to the initial state when the external force is withdrawn.

[0040] In this embodiment, an oil injection control component is arranged on the oil bottle 3. After the e-liquid in the first oil chamber 20 is used up, the user can install the oil bottle 3 on the e-cigarette body 10 to make the oil inlet hole 201 and the oil outlet channel 34 communicate, and by operating the oil injection control component, the oil outlet channel 34 can be made to conduct. In this way, the e-liquid in the second oil chamber 30 enters the first oil chamber 20 through the oil outlet channel 34 and the oil inlet hole 201, realizing the addition of e-liquid to the cartridge 2, so as to increase the usage duration of the e-cigarette body 10 and the number of puffs inhaled by the user. Moreover, after the user withdraws the operation of the oil injection control component, the oil injection control component returns to the initial state, that is, it will block the oil injection and outlet channel 34, realizing controllable oil injection, preventing the oil outlet channel 34 and the oil inlet hole 201 from being always conducted, preventing the e-liquid in the first oil chamber 20 from being excessive, effectively reducing the probability of excessive e-liquid being inhaled by the user, and improving the user experience.

[0041] In one embodiment, the e-cigarette body 10 further includes a main body 1, and the cartridge 2 is detachably arranged on the main body 1. When the cartridge 2 is assembled onto the main body 1, it is electrically connected to the main body 1. In this way, when the cartridge 2 is damaged or has a poor user experience, the cartridge 2 can be replaced without replacing the entire e-cigarette body 10, effectively reducing the cost for users to use the e-cigarette.

[0042] In one embodiment, the oil bottle 3 is non-removable after being assembled onto the e-cigarette body 10. Of course, in other embodiments, to increase the usage duration of the e-cigarette body 10, the oil bottle 3 is removable after being assembled onto the e-cigarette body 10 to facilitate the user to replace the oil bottle 3.

[0043] In the above embodiment, the oil bottle 3 can be installed on the cartridge 2 to enable the oil outlet channel 34 to communicate with the oil inlet hole 201 when the oil bottle 3 is installed on the e-cigarette body 10. Alternatively, the oil bottle 3 can be installed on the main body 1, and it can also enable the oil outlet channel 34 to communicate with the oil inlet hole 201 when the oil bottle 3 is installed on the e-cigarette body 10.

[0044] In one embodiment, an oil absorption cotton 27 for adsorbing e-liquid is arranged in the first oil chamber 20. In this way, the e-liquid can be adsorbed by the oil absorption cotton 27, and the e-liquid will not leak out from the oil inlet hole 201. A first sealing ring 22 is arranged on the oil inlet hole 201. When the oil outlet channel 34 communicates with the oil inlet hole 201, the first sealing ring 22 abuts against the oil bottle 3 to prevent the e-liquid from leaking between the oil outlet channel 34 and the oil inlet hole 201 when they communicate.

[0045] In one embodiment, an oil-permeable cotton 23 is arranged in the oil inlet hole 201. Among them, the material of the oil-permeable cotton 23 is the same as that of the oil absorption cotton 27. By using the oil-permeable cotton 23, the leakage of the e-liquid can be further prevented, and by using the oil-permeable cotton 23, the injection speed of the e-liquid can be reduced when the oil bottle 3 injects e-liquid into the cartridge 2.

[0046] In one embodiment, the injection control assembly includes an operating member 35, a first elastic member 37 and a covering member 36 arranged on the oil bottle 3. The covering member 36 is configured to move and conduct the oil outlet channel 34 when the operating member 35 is operated. The covering member 36 returns to the initial state through the first elastic member 37 when the operating member 35 is released. The covering member 36 blocks the oil outlet channel 34 in the initial state. In this way, when the user presses or pulls the operating member 35, the covering member 36 can be moved to open the oil outlet channel 34 to realize the addition of e-liquid from the oil bottle 3 to the cartridge 2.

[0047] In one embodiment, the operating member 35 and the covering member 36 are two independent components. The oil bottle 3 is provided with a first installation cavity 301 below the oil outlet passage 34. The first elastic member 37 is placed in the first installation cavity 301. The operating member 35 is movably arranged along the length or width direction of the oil bottle 3 and inserted into the first installation cavity 301. One end opening of the oil outlet passage 34 is the oil outlet 341, and the oil outlet 341 communicates with the second oil cavity 30. The covering member 36 includes a connecting member 362, and an abutting block 363 and a blocking block 361 spaced apart on the connecting member 362. The abutting block 363 and the first elastic member 37 are both placed in the first installation cavity 301. The first elastic member 37 is sleeved on the connecting member 362. Two ends of the first elastic member 37 are respectively connected to the abutting block 363 and the top wall of the first installation cavity 301. The connecting member 362 is at least partially placed in the oil outlet passage 34. The abutting block 363 contacts the operating member 35. The contact surface between the operating member 35 and the abutting block 363 is an inclined surface or an arc surface. The blocking block 361 moves away from the oil outlet 341 when the operating member 35 is pressed to open the oil outlet 341. The blocking block 361 covers the oil outlet 341 in the initial state. By using the inclined surface or the arc surface, when the operating member 35 is pressed, the abutting block 363 can be pushed to move, that is, the blocking block 361 is driven by the connecting member 362 to move away from the oil outlet 341 to open the oil outlet passage 34, so that the e-liquid in the second oil cavity 30 can be added to the first oil cavity 20 through the oil outlet passage 34 and the oil inlet hole 201. And when the pressing force is withdrawn, the first elastic member 37 is reset to push the abutting block 363 to move. The connecting member 362 is used to drive the blocking block 361 to block the oil outlet passage 34 to prevent the oil outlet passage 34 from continuing to discharge oil, realizing controllable oil injection. And when the abutting block 363 is reset, the operating member 35 can be pushed back to the initial position.

[0048] In one embodiment, the blocking block 361 is located above the oil outlet 341. The top of the first installation cavity 301 is provided with a first avoidance hole 302 communicating with the oil outlet passage 34.

The blocking block 361 is provided with a third sealing ring 330 for sealing the oil outlet 341. The blocking block 361 moves upward to open the oil outlet 341 when the operating member 35 is pressed. The blocking block 361 moves downward to drive the third sealing ring 330 to seal the oil outlet 341 when the operating member 35 is released. By using the second sealing ring 360, e-liquid can be prevented from entering the first installation cavity 301 between the connecting member 362 and the annular surrounding wall 331, preventing oil leakage. The oil outlet 341 is sealed by using the third sealing ring 330 to prevent e-liquid from leaking out of the oil outlet passage 34 when the oil bottle 3 does not inject oil into the cartridge 2, playing a sealing role.

[0049] In one embodiment, the oil injection control assembly further includes a second elastic member 39 disposed in the first installation cavity 301. The second elastic member 39 is located between the 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 to return to its initial position when the operating member 35 is released. By utilizing the second elastic member 39 and the resetting force of the first elastic member 37 in cooperation, the operating member 35 can return to its initial position more quickly, and the stopper 361 can return to its initial state faster.

[0050] In the above embodiment, for the convenience of the production and manufacturing of the oil bottle 3, the oil bottle 3 includes a first outer shell 31, an intermediate housing 33, and a first bottom shell 38.
