The insertion depth in the second blind hole 122 prevents the puncture position from being pushed away due to the insertion of the first electrode 13 and the second electrode 14 too deep, thereby causing the leakage of the smoke liquid. It should be noted that when the first electrode 13 and the second electrode 14 are installed in place, the lower end surface of the first electrode 13 and the lower end surface of the second electrode 14 are both flush with the lower end surface of the base 16 , which makes the cartridge 10 more beautiful. . It can be understood that in other embodiments, both the first installation groove 162 and the second installation groove 162 can be omitted.

In order to isolate the smoke liquid from the outside air, it can prevent the smoke liquid from entering the atomizing head 15 due to changes in temperature and air pressure during the transportation process and contact with the air to deteriorate, and it can also further prevent the atomizing head 15 from entering too much smoke liquid. And the leakage of smoke liquid occurs. When the user uses it, the lifting rod 18 is pulled upward, and the sleeve 17 moves upward together with the driving of the lifting rod 18 to open the liquid inlet 1511, so that the liquid smoke communicates with the atomization chamber 150 through the liquid inlet 1511.

The first pole 2112 and the second pole 2113 are symmetrically arranged on both sides of the installation pole 2114 , that is, the first pole 2112 and the second pole 2113 are symmetrically arranged relative to the central axis of the cartridge housing 11 . When the 10 is installed on the power supply device 20, the positive and negative polarities do not need to be considered, and the effect that both positive and negative plugging can be used is achieved. Specifically, when the cartridge 10 and the power supply device 20 are in the first connection state, the first pole 2112 is in contact with the first electrode 13 and is electrically connected. When the cartridge 10 and the power supply device 20 are in the second connection state, the A pole 2113 is in contact with the second electrode 14 and is electrically connected. In this embodiment, the transition from the first connection state to the second connection state is obtained by rotating the power supply device 20 relative to the cartridge 10 by 180°, thereby realizing Both positive and negative plugs can be electrically connected. The sensor 23 is installed at the lower end of the partition plate 211 and closes the sensing channel 2115 , and the sensing end of the sensor 23 communicates with the sensing channel 2115 . When the cartridge 10 and the power supply device 20 are installed in place, the installation post 2114 is partially inserted into the base 16 , and the sensing channel 2115 communicates with the sensing through hole 163 .

In a specific embodiment, the power supply device 20 further includes a circuit board, the battery 22 and the sensor 23 are electrically connected to the circuit board, and the sensor 23 is a pressure sensor. When the user performs a smoking operation, negative pressure is generated in the induction channel 2115 due to the suction effect, and the sensor 23 senses the air pressure change in the induction channel 2115 and transmits the air pressure change signal to the circuit board. After the circuit board receives the signal Then, the battery 23 is controlled to supply power to the heating structure 152, thereby heating the liquid smoke, so that the liquid smoke generates smoke under the action of heating, and automatic control is realized. It can be understood that the sensor 23 can also be an airflow sensor.

In the cartridge 10 provided by the present invention, the sealing member 12 can be pierced by the liquid injection needle, so as to facilitate the injection of smoke liquid into the liquid storage cavity 110 through the liquid injection needle, and after pulling out the liquid injection needle , the pierced position on the sealing member 12 can be automatically restored to seal the liquid storage chamber 110 again, so as to prevent leakage of the smoke liquid in the liquid storage chamber 110 after the liquid injection is completed. In addition, after the liquid injection is completed, the first blind hole 121 and the second blind hole 122 are blocked by the first electrode 13 and the second electrode 14 respectively. In this way, even if the smoke liquid in the liquid storage chamber 110 leaks through the piercing position, the leakage The smoke liquid can also be sealed by the first electrode 13 and/or the second electrode 14, which further prevents the smoke liquid from leaking.

Since the electronic cigarette provided by the present invention has all the technical features of the above-mentioned cartridge 10 , it has the same technical effect as the above-mentioned cartridge 10 .

Taking the above ideal embodiments according to the present invention as inspiration, through the above description, the relevant staff can make various changes and modifications without departing from the scope of the present invention. The technical scope of the present invention is not limited to the content in the description, and its technical scope must be determined according to the scope of the claims.
