In a real In the embodiment, the smoke passage 222 extends from the bottom end of the peripheral wall 22 in the axial direction to the top end of the peripheral wall, and penetrates the top end and the bottom end of the peripheral wall 22, so that the airflow flows from the bottom end of the outlet passage 222 and flows out from the top end of the peripheral wall 22. . The arrangement of the inlet passage 221 and the outlet passage 222 in the shell wall 22 can make full use of the peripheral space of the cartridge 20, and it is not necessary to dispose the portion of the air passage in the middle of the electronic cigarette having a large number of components, thereby further reducing the volume of the electronic cigarette. The up and up settings can also effectively prevent leakage. A liquid injection hole 25 is radially opened in the peripheral wall 22 for injecting the liquid liquid into the liquid storage chamber 23, and the liquid injection hole 25 is not connected to the air inlet passage 221 or the smoke outlet passage 222 to ensure direct injection. Injecting into the liquid storage chamber 23, for example, the liquid injection hole 25 can be opened on the peripheral wall 22 where it does not communicate with the intake passage 221 or the smoke outlet passage 222, such as above the intake passage 221, and in addition, the liquid injection hole 25 The top wall 21 can be opened axially.

In this embodiment, the cartridge 20 can be divided into a lower half and an upper half integrally formed with the lower half (the illustration is separated by the center line 201) according to the set position, and the lower half is installed in the lower casing 12. The upper half is mounted in the upper casing 11. A latching block 26 is protruded from the outer side of the peripheral wall of the cartridge 20, and the latching block 26 is formed at a joint between the lower half and the upper half for holding the card to the joint of the upper shell 11 and the lower shell 12 Inside the hole 13. In one embodiment, the intake passage 221, the intake port 24, and the liquid injection hole 25 are all open on one side of the lower half body peripheral wall 22, and the intake passage 221 extends from the bottom end of the peripheral wall 22 by a predetermined height and then communicates with the The air inlet 24, the liquid injection hole 25 is located directly above the air inlet 24, and the top end of the liquid injection hole 25 is flush with the center line 201. The shape of the liquid injection hole 25 is not limited. The liquid hole 25 is formed by a rectangular notch fitted with a central circular hole to facilitate the installation of the liquid filling plug 27 (see Fig. 2). The smoke outlet passage 222 is opened on the side of the peripheral wall 22 opposite to the intake chamber 23 and the intake passage 221, and the outlet passage 222 extends from the bottom end of the peripheral wall 22 through the lower half of the peripheral wall and then extends into the upper half of the peripheral wall.

The atomizing assembly 30 includes an atomizing head 31. Referring to FIG. 6 and FIG. 7, the atomizing head 31 has a cylindrical shape, and includes a first housing 311 disposed at one end, a second housing 312 disposed at the other end, and a setting. The insulating member 313 between the first housing 311 and the second housing 312, the first housing 311 and the second housing 312 as the peripheral wall of the atomizing head 31 are electrically conductive, respectively for connecting two electric poles One of them is connected to the positive pole and the other is connected to the negative pole. The first housing 311 and the second housing 312 are each provided with an electrical connecting leg 314 for connecting the electrodes. The atomizing head 31 opens the atomizing heating passage 315 in the axial direction and penetrates both ends of the atomizing head 31. The first housing 311 is longer than the second housing 312. The outer peripheral surface of the first housing 311 is provided with a liquid inlet hole 3111 for the liquid liquid of the liquid storage chamber to flow into the atomizing head 31 through the liquid inlet hole 3111. It is noted that the atomization heating channel 315 is a place where the smoke liquid contacts the air to be atomized into smoke, and is available for airflow, and air can enter from one end of the atomization heating channel 315, and the smoke liquid is used in the The atomization heating channel 315 generates smoke and then exits from the other end.

In one embodiment, the atomizing head 31 includes a heat generating member 316 and a liquid absorbing member 317. The liquid absorbing member 317 is wrapped around the outer periphery of the heat generating member 316 and integrally mounted in the inner cavity of the first housing 311. 316 is selected as a spiral formed by spiraling a heating wire, and the inside of the spiral body serves as an atomizing heating passage 315.

The pieces are all disposed in the atomization chamber. In this way, the smoke liquid flowing into the liquid storage chamber of the cartridge 20 flows through the liquid inlet hole 3111 and is adsorbed by the liquid suction member 317. By heating the heating wire 316, the heating wire 316 generates heat to evaporate the liquid liquid on the liquid suction member 317 into smoke. The airflow of the intake passage 221 enters the atomization heating passage 315, and the smoke belt in the atomization heating passage 315 is sent out through the outlet passage 222. In this embodiment, the first housing 311 is selectively connected to the positive pole, and the second housing 312 is selected to be connected to the negative pole. It can be understood that the polarity of the connection of the first housing 311 and the second housing 312 is interchangeable.
