It has similar appearance and taste to those of traditional cigarette, even more than traditional cigarette, and can suck cigarette and taste like traditional cigarette. Because the electronic cigarette does not contain tar, suspended particles and other harmful ingredients in the traditional cigarette, the electronic cigarette gradually replaces the traditional cigarette in the market.
The existing electronic cigarette generally comprises a power supply device and an atomizing device which is arranged on the power supply device and electrically connected with the power supply device, wherein a heating component, an oil storage cavity and an airflow channel for a user to suck are arranged in the atomizing device, and the heating component is partially accommodated in the airflow channel and heats smoke liquid adsorbed from the oil storage cavity under the driving action of current to generate smoke for the user to suck.
However, the temperature in the airflow channel is high during operation, which results in a high air pressure value in the oil storage chamber, thereby squeezing the tobacco smoke out of the adsorption amount of the heating component, and causing excessive tobacco liquid to easily flow out of the airflow channel.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The invention provides an electronic cigarette, which comprises a power supply device 1000 and an external load (not shown) arranged on the power supply device 1000, wherein the external load can be an atomizing device, an oil storage device and the like. When the atomization device is installed in the power supply device 1000, the conductive terminal contacts with the electrode of the power supply device 1000 to establish electrical connection. The heating body heats the smoke liquid absorbed by the oil guide piece from the oil storage cavity under the current drive of the power supply device 1000, so as to generate smoke for a user to suck through the airflow channel.
Referring to fig. 1 to 8, in the embodiment of the present invention, the power supply device 1000 includes a housing 200, and a skeleton and electronic components disposed inside the housing 200, and the electrode contact structure 100 of the electronic cigarette is mounted on the power supply device 1000, so that the power supply device 1000 and the atomization device are electrically connected. The electrode contact structure 100 includes a negative electrode conductive member 30, a positive electrode conductive member 10, and an insulating member 50. One end of the negative conductive member 30 abuts against the power supply device 1000, and the other end is inserted into the power supply device 1000, and is provided with a mounting hole 31 communicated with the inside of the power supply device 1000; one end of the insulating member 50 is elastically abutted against the internal structure of the power supply device 1000, and the other end is elastically sleeved on the peripheral surface of one end of the negative electrode conductive member 30 inserted into the power supply device 1000, and the end part of the negative electrode conductive member 30 is covered in the power supply device 1000; one end of the positive conductive member 10 is accommodated in the mounting hole 31 and spaced apart from the negative conductive member 30, and the other end thereof is inserted into the insulating member 50 in an interference manner.
According to the electrode contact structure 100 of the electronic cigarette, the positive electrode conductive piece 10 is inserted into the insulating piece 50 in an interference manner, so that the insulating piece 50 is tightly attached to the positive electrode conductive piece 10, and the insulating piece 50 is elastically abutted to the internal structure of the power supply device 1000, so that the positive electrode conductive piece 10 can move along with the insulating piece 50 under the action of external force, so that the power supply device 1000 can be adapted to external loads of various types, and meanwhile, oil cannot permeate into the power supply device 1000 from a gap between the positive electrode conductive piece 10 and the insulating piece 50. The insulating member 50 covers the end of the negative conductive member 30 in the power supply device 1000, and elastically sleeves the outer peripheral surface of the end of the negative conductive member 30 inserted into the power supply device 1000. It is understood that, at the time of normal user suction, the end of the power supply device 1000 provided with the electrode contact is the upper end of the power supply device 1000, that is, the insulating member 50 is turned upward, and the negative electrode conductive member 30 is elastically fitted over the outer circumferential surface of the end of the power supply device 1000, and covers the negative electrode conductive member 30 in the power supply device 1000. Therefore, the oil liquid permeating into the mounting hole 31 needs to overcome the gravity and pass through the gap between the insulating member 50 and the outer peripheral surface of the negative conductive member 30, and then permeates into the power supply apparatus 1000 after permeating into the end portion of the insulating member 50, and the insulating member 50 is elastically sleeved on the outer peripheral surface of the negative conductive member 30, so that the possibility that the oil liquid permeates into the power supply apparatus 1000 is further reduced.

And the periphery of the insertion part 33 is irregularly arranged, thereby effectively preventing the negative conductive member 30 from rotating in the long-term use process. The positive conductive piece 10 comprises a contact head 11 with a large diameter and a wiring terminal 12 with a small diameter, wherein the wiring terminal 12 is integrally formed with the contact head 11, the wiring terminal 12 is inserted into the insulating piece 50 in an interference mode so that the insulating piece 50 and the positive conductive piece 10 are tightly attached, and the positive conductive column is connected to the contact head 11 and limited in abutting mode when in contact with the insulating piece 50 in an inserted mode so that the contact head 11 partially protrudes out of the insertion hole 523. The conductive terminal of the atomization device is effectively prevented from extruding the positive conductive piece 10 when the atomization device is installed in the power supply device 1000, and the positive conductive piece 10 is completely pressed into the insulating piece 50, so that the electric connection cannot be established.
Further, as shown in fig. 1 or fig. 2, in the embodiment of the present invention, at least one elastic sealing ring 332 is further disposed between the insulating member 50 and the negative conductive member 30, an inner ring of the at least one sealing ring 332 is elastically sleeved on an outer peripheral surface of one end of the negative conductive member 30 inserted into the power supply device 1000, and an outer ring of the at least one sealing ring is elastically abutted to the insulating member 50.

It is understood that, in the practical application, it is not limited to the above-mentioned embodiment that the elastic sealing ring 332 is disposed between the insulating member 50 and the inserting portion 33 to achieve the elastic sleeving of the insulating member 50 on the outer peripheral surface of the inserting portion 33. For example, in another embodiment of the present invention, the outer peripheral surface of the insulating member 50 may be entirely covered with elastic silica gel, and then sleeved on the outer periphery of the inserting portion 33, which also falls within the protection scope of the present invention.
Further, as shown in fig. 1 or fig. 5, in the embodiment of the present invention, one of the insulating member 50 and the negative conductive member 30 is provided with a mounting groove 331 corresponding to each of the sealing rings 332, and one of the sealing rings 332 is mounted in one of the mounting grooves 331 and partially protrudes out of the mounting groove 331;
alternatively, at least one elastic rib is protruded from the surface of the insulating member 50 facing the negative conductive member 30 to form the at least one sealing ring 332. Here, in this embodiment, the insertion portion 33 is provided with a mounting groove 331 corresponding to each of the sealing rings 332, and the sealing ring 332 is sleeved in the mounting groove 331, so as to effectively prevent the sealing ring 332 from being separated. Further, the atomization device is mounted in the mounting hole 31 to press the insulating member 50, so that when the insulating member 50 slides, a gap is formed between the insulating member 50 and the insertion portion 33, which may result in oil leakage.
It should be understood that, in practical applications, the installation groove 331 is not limited to the above-mentioned manner of installing the installation groove 331 on the outer circumference of the insertion portion 33 to fix the sealing ring 332. For example, as shown in fig. 3, in other embodiments of the present invention, the surface of the insulating member 50 facing the insertion part 33 may be provided with the mounting groove 331; as another example, as shown in fig. 4, in another embodiment of the present invention, a plurality of elastic sealing rings 332 may be further disposed between the insulating member 50 and the negative conductive member 30, the sealing rings 332 are disposed at intervals along the direction in which the negative conductive member 30 is inserted into the power supply device 100, a plurality of mounting grooves 331 are alternately disposed on the insulating member 50 and the negative conductive member 30 corresponding to the sealing rings 332, one sealing ring 332 is received in one mounting groove 331, and a portion of the sealing ring is protruded out of the mounting groove 331, here, in this embodiment, the sealing rings 332 are fixed by alternately disposing the mounting grooves 331 on the insulating member 50 and the insertion portion 33, when the insulating member 50 slides under the extrusion force of the atomizing device, the two sealing rings 332 abut against each other to have a certain limiting effect, and, when the sealing rings 332 slide relatively, the friction surfaces of the alternately disposed sealing rings 332 are just dislocated, thereby effectively preventing the phenomenon that the abrasion surfaces of the plurality of sealing rings 332 are consistent to cause the reduction of the sealing effect.

Here, in the present embodiment, the partition portion 52 is provided with the boss 521 to be inserted into the mounting hole 31, so that the thickness thereof is thick, thereby preventing the partition portion 52 from being pressed through due to a large pressing force applied to the positive electrode conductor 10 when the atomization device is mounted in the mounting hole 31. Meanwhile, the boss 521 is inserted into the mounting hole 31, so that the positioning effect is achieved, and the mounting and alignment are effectively facilitated.
Specifically, as shown in fig. 1 to 5, in the embodiment of the present invention, the depth of the inserting hole 523 is greater than the depth of the positive conductive member 10, so that the end of the positive conductive member 10 inserted is received in the inserting hole 523; here, in this embodiment, the connection cable of the electronic component inside the power supply device 1000 firstly passes through the inserting hole 523 to be welded to the terminal 12 of the positive conductive component 10, and after the welding is completed, the connection cable is inserted into the inserting hole 523 along with the terminal 12, because the depth of the inserting hole 523 is greater than the inserting length of the terminal 12, the welding position of the terminal 12 and the connection cable is accommodated in the inserting hole 523, and when the connection cable is detached from the terminal 12, the connection cable is still accommodated in the inserting hole 523, so that the potential safety hazard of short circuit caused by contact with other electronic components inside the power supply device 1000 is avoided, and the safety performance of the product is effectively improved.

Further effectively promote sealed effect.
Specifically, a sealing sleeve (not shown) having elasticity is further sleeved on the outer peripheral surface of the boss 521, and the outer peripheral surface of the sealing sleeve is elastically abutted to the inner peripheral wall of the mounting hole 31.
