one end of the electrode 70 is exposed from the cartridge 1000 to facilitate electrical connection of the cartridge and the other end is in contact with a conductive element of the atomizer 30, thereby electrically connecting a power source in the cartridge 1000 to the atomizer 30.

And an insulator 80 for preventing an electrical connection between the electrode 70 and the base of the metal cargo tank 10.

As shown in fig. 2 and 3, since the electrode 70 passes through the base of the metal oil tank 10 from the outside of the cartridge 1000 into the flue and then contacts the atomizing device 30, the electrode 70 is easily contacted with the metal oil tank 10 to cause a short circuit. The present embodiment is provided with the insulating member 80 for isolating the electrode 70 from the metal oil tank 10, so that the electrode 70 passing through the metal oil tank 10 does not contact the metal oil tank 10 under the effect of the electrical isolation of the insulating member 80. Wherein the insulating member 80 is made of an insulating material, and an electrical connection is not formed even in a case where both the metal oil tank 10 and the electrode 70 are in contact with the insulating material over a large area.

As shown in fig. 4 and fig. 6, in the present embodiment, the insulating member 80 blocks the base of the metal cargo tank 10 from the electrode 70 in a specific manner: the one end relative with atomizing device 30 of metal oil tank 10 base is formed with first opening 42, be formed with on the insulating part 80 and be used for spacing first through-hole 81 to electrode 70, the one end of electrode 70 pass behind first opening 42 and first through-hole 81 with atomizing device 30 electricity is connected, first through-hole 81 is used for restricting the relative position between electrode 70 and the metal oil tank 10 base to form the electricity after avoiding producing the contact between electrode 70 and the metal oil tank 10 base and connect.

In this embodiment, an opening is provided in the base of the metal cargo tank 10 so that the electrode 70 can pass through the base of the metal cargo tank 10 from the position of the opening in the base of the metal cargo tank 10 without contacting the base of the metal cargo tank 10. Meanwhile, the present embodiment provides a through hole on the insulating member 80, through which the electrode 70 can pass, so as to contact the electrode 70 with the conductive element on the atomization device 30. Meanwhile, the electrode 70 is limited by the inner wall of the through hole of the insulating part 80 and the outer wall of the electrode 70, so that the electrode 70 is positioned at a position where the electrode 70 is not in contact with the metal oil tank 10, and the electrode 70 can be well prevented from being electrically connected with the base of the metal oil tank 10 to cause short circuit.

In order to ensure the absolute insulation state between the electrode 70 and the base of the metal oil tank 10, in this embodiment, the surface of the insulating member 80 opposite to the atomizing device 30 is lower than the inner wall of the base facing the atomizing device 30, and the distance from the edge of the first through hole 81 to the inner edge of the first opening 42 is less than the first preset distance. Wherein the size of the insulating member 80 is larger than the size of the first opening 42 so that the insulating member 80 does not come out of the first opening 42. The insulating member 80 may be an insulating sheet, and the insulating sheet is placed on the inner wall of the base of the metal oil tank 10 facing the atomizing device 30 and is connected with the inner wall in a low manner. While the sectional shape of the insulating sheet in the axial direction of the electrode 70 is larger than that of the first opening 42 in the axial direction of the electrode 70, so that the insulating sheet can well seal the first opening 42. Because the first through hole 81 determines the position of the electrode 70 relative to the base of the oil tank 10, the embodiment makes the distance from the edge of the first through hole 81 to the inner edge of the first opening 42 smaller than the first preset distance, so that a safe distance can be kept between the electrode 70 passing through the first through hole 81 and the base of the metal oil tank 10, and the electrode 70 can be effectively prevented from being electrically connected with the base of the metal oil tank 10 after being contacted.

During assembly, the electrode 70 is sequentially penetrated through the insulating member 80 and the base of the metal oil tank 10 from the base of the metal oil tank 10 toward one end of the atomizing device 30, so that the baffle ring 71 is positioned on one side of the base of the metal oil tank 10 toward the atomizing device 30. When the electrode 70 moves away from the atomizing device 30 under the action of an external force, the baffle ring 71 moves to a position contacting with the insulating member 80 along with the electrode 70, so that the outer diameter of the baffle ring 71 is larger than the inner diameter of the first through hole 81, the insulating member 80 can block the baffle ring 71, the baffle ring 71 cannot pass through the first through hole 81, and the electrode 70 cannot retreat. This effectively ensures reliable contact of the electrode 70 with the atomizing device 30.
