The insulating member 80 is used to prevent electrical connection between the electrode 70 and the base of the metal oil tank 10 .

As shown in FIG. 2 and FIG. 3 , since the electrode 70 passes through the base of the metal oil tank 10 from the pod 1000 and enters 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 Case. In this embodiment, an insulating member 80 is provided to isolate the electrode 70 from the metal oil tank 10 , so that the electrode 70 passing through the metal oil tank 10 will not come into contact with the metal oil tank 10 due to the electrical isolation of the insulating member 80 . The insulating member 80 is made of insulating material, and even when the metal oil tank 10 and the electrode 70 are in large-area contact with the insulating material, an electrical connection will not be formed.

As shown in FIG. 4 and FIG. 6 , in this embodiment, the insulating member 80 blocks the base of the metal oil tank 10 and the electrode 70 in a specific manner as follows: the end of the base of the metal oil tank 10 opposite to the atomizing device 30 forms a There is a first opening 42, and a first through hole 81 for limiting the electrode 70 is formed on the insulating member 80. One end of the electrode 70 passes through the first opening 42 and the first through hole 81 and then communicates with the mist. The chemical device 30 is electrically connected, and the first through hole 81 is used to limit the relative position between the electrode 70 and the base of the metal oil tank 10 so as to avoid contact between the electrode 70 and the base of the metal oil tank 10 to form an electrical connection.

In this embodiment, an opening is provided on the base of the metal oil tank 10 so that the electrode 70 can pass through the base of the metal oil tank 10 from the opening position of the base of the metal oil tank 10 without contacting the base of the metal oil tank 10 . Meanwhile, in this embodiment, a through hole is provided on the insulating member 80 , and the electrode 70 can pass through the through hole, so as to realize the contact between the electrode 70 and the conductive element on the atomizing device 30 . At the same time, the inner wall of the through hole of the insulating member 80 and the outer wall of the electrode 70 are used to limit the electrode 70, so that the electrode 70 is located in a position where it will not contact the metal oil tank 10, so that the electrode 70 and the metal oil tank can be well avoided. 10 The base forms an electrical connection, causing a short circuit.

In order to ensure absolute insulation between the electrode 70 and the base of the metal oil tank 10 , in this embodiment, the side of the insulating member 80 opposite to the atomizing device 30 is in low contact with the inner wall of the base facing the atomizing device 30 . , the distance between the edge of the first through hole 81 and the inner edge of the first opening 42 is smaller than the first preset distance. The size of the insulating member 80 is larger than that of the first opening 42 , so that the insulating member 80 will 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 connected to the inner wall. Meanwhile, the cross-sectional shape of the insulating sheet along the axial direction of the electrode 70 is larger than the cross-sectional shape of the first opening 42 along the axial direction of the electrode 70 , so that the insulating sheet can seal the first opening 42 well. Since the first through hole 81 determines the position of the electrode 70 relative to the base of the oil tank 10, in this embodiment, the distance between the edge of the first through hole 81 and the inner edge of the first opening 42 is smaller than the first preset distance, so that the connection can be Ensuring a safe distance between the electrode 70 passing through the first through hole 81 and the base of the metal oil tank 10 can effectively prevent the electrode 70 from contacting the base of the metal oil tank 10 to form an electrical connection.

During assembly, the electrode 70 is passed through the insulating member 80 and the base of the metal oil tank 10 from the end of the base of the metal oil tank 10 toward the atomizing device 30 in turn, so that the retaining ring 71 is located at one end of the base of the metal oil tank 10 facing the atomizing device 30. side. When the electrode 70 is moved away from the atomizing device 30 by the external force, the blocking ring 71 moves with the electrode 70 to the position where it contacts the insulating member 80, so that the outer diameter of the blocking ring 71 is larger than the inner diameter of the first through hole 81, In this way, the insulating member 80 can block the blocking ring 71, and the blocking ring 71 cannot pass through the first through hole 81, so that the electrode 70 can no longer retreat.

The first layer of casing 22 through which the flue gas directly flows is wrapped in the second layer of casing 23 and will not be in direct contact with the user. When the user is using it, the value needs to contain the second shell 23 located at the outermost layer. In this way, only the second shell 23 located at the outermost layer will directly contact the user's mouth during use, and will not be scalded by the high temperature generated by the smoke, which significantly improves the safety of the electronic cigarette. In addition, the first layer of casing 22 may be formed by the middle part of the second layer of casing 23 , after being recessed to a certain depth in the direction of the atomizing device 30 .

In addition, the use of in-mold injection molding can integrate the material with fast heat dissipation and high temperature resistance with the oil tank 10 to form the air passage 50, so that the air passage 50 can be used to cool the flue gas while preventing the leakage of the e-liquid, so that the flue gas can be cooled down through the air passage 50. The high-temperature atomized flue gas quickly dissipates heat in the process of flowing from the air passage 50 to the cigarette holder 20, which can prevent the user from being scalded by the high-temperature flue gas.

In this embodiment, the stainless steel material and the oil tank 10 are integrally formed by an in-mold injection process. The stainless steel has good chemical stability, high strength, good temperature resistance, and fast heat dissipation. The air passage 50 in this embodiment extends from the smoke outlet of the oil tank 10 to the position of the atomizing device 30 , so that the smoke can be rapidly evacuated by the air passage 50 from the time the smoke oil is atomized until it enters the smoking port 21 . Cooling can significantly improve the cooling effect.

In this embodiment, an airway connector 60 is also included, the airway 50 is sleeved into one end of the airway connector 60, and the opposite end of the airway connector 60 is inserted into the atomization chamber. In this embodiment, the airway connector 60 is used to reliably communicate the airway 50 and the atomization chamber. The two ends of the airway connector 60 are respectively connected to the airway 50 and the atomization chamber. The specific connection method is to first insert the airway 50 into one end of the airway connector 60, and then insert the other end of the airway connector 60 into the atomization chamber, so that the airway 50 can be atomized. Reliable connection of chambers.
