The invention provides an installation structure of a conductive contact of an electronic cigarette, as shown in FIGS. 1-3, wherein the installation structure comprises an electronic cigarette body 200 provided with a receiving groove 201 and a conductive contact 100 which is installed in the receiving groove 201 and is exposed to an opening of the receiving groove 201 at one end thereof, wherein the conductive contact 100 comprises a first contact 1, a second contact 2, an insulating part 4 and a sealing part 3 provided with an installation hole 13, and the second contact 2 is partially received in the installation hole 13; the insulating part 4 is sleeved on the second contact 2 and is partially received in the installation hole 13 to separate the first contact 1 from the second contact 2; the sealing part 3 is partially sleeved on the insulating part 4 and elastically abuts against the first contact 1, and the sealing part is partially sleeved on the second contact 2 and elastically abuts against the insulating part 4. In this embodiment, the sealing part 3 seals the gap between the insulating part 4 and the first contact 1 and the gap between the insulating part 4 and the second contact 2 to improve the oil-proof performance of the conductive contact 100.

In this embodiment, as shown in FIG. 2 and FIG. 5, the insulating part 4 comprises an upright post 42 provided with a through hole 421 and a chassis 41 sleeved on the periphery of the upright post 42, the upright post 42 is sleeved on the second contact 2 through the through hole 421, and the periphery of the upright post 42 is partially received in the installation hole 13. Preferably, the periphery of the upright post 42 is in interference fit with the installation hole 13. The first contact 1 and the second contact 2 are spaced apart by the upright post 42 so that they are not in contact with each other. In this way, when the first contact 1 and the second contact 2 are electrically connected to the positive and negative poles of the body of the electronic cigarette, no short circuit will occur. Further, the inside of the installation hole 13 is also concavely provided with an annular slot adapted to the upright post 42. The top surface of the upright post 42 partially abuts against an inner wall of the annular slot to play a limiting role. The side surface of the upright post 42 abuts against the other inner wall of the annular slot. Further, the chassis 41 is fastened to the electronic cigarette body 200 and is located between the bottom end of the receiving groove 201 and the bottom end of the first contact 1 and has gaps with the bottom end of the receiving groove 201 and the bottom end of the first contact 1, respectively. The bottom end of the first contact 1 is an end far away from the opening of the receiving groove 201.

In this embodiment, as shown in FIG. 2, FIG. 3, and FIG. 4, the sealing part 3 comprises a first sealing ring 31 and a second sealing ring 32 which are arranged in parallel and are concentric with each other. The first sealing ring 31 is located directly above the second sealing ring 32 (i.e., the first sealing ring 31 is close to the opening). The first sealing ring 31 is sleeved on the upright post 42 and is clamped between the chassis 41 and the bottom end of the first contact 1. The first sealing ring 31 seals the gap between the chassis 41 and the first contact 1, so as to prevent oil from leaking from the inner wall of the first contact 1 to the inner wall of the receiving groove 201 through the gap and corroding other components in the receiving groove 201.

Further, one end of the second sealing ring 32 is sleeved on the second contact 2 and elastically abuts against the second contact 2, while the other end thereof is clamped between the chassis 41 and the bottom end of the receiving groove 201 to seal the gap between the second contact 2 and the insulating part 4. At the same time, one end elastically abuts against the second contact 2, and the other end is clamped between the chassis 41 and the bottom end of the receiving groove 201, so that one end of the second sealing ring clamped between the chassis 41 and the receiving groove 201 may be used as a fixed end, providing a fulcrum for elastic deformation and up-down oscillation of the other end.

Further, as shown in FIG. 3, in order to improve the sealing effect of the second sealing ring 32, one end of the second sealing ring 32 sleeved on the second contact 2 is convexly provided with a collar 321 in the axial direction. The collar 321 is sleeved on the second contact 2, and the inner wall of the collar 321 elastically abuts against the periphery of the second contact 2, increasing the contact area between the sealing part 3 and the second contact 2 to prevent oil from leaking down the outer surface of the second contact 2. Further, the collar 321 is convexly provided with a flange 3211 toward the second contact 2. That is, the inner wall of the collar 321 is provided with a flange 3211 toward the center of a circle. The end of the flange 3211 far away from the collar 321 elastically abuts against the second contact 2. That is, the through hole 421 encircled by the flange 3211 is in interference fit with the second contact 2. The flange 3211 may be rectangular, square, polygonal, or arc-shaped. In one embodiment of the invention, the flange 3211 is in the shape of a circular arc, and the circular arc parabolic structure helps the flange 3211 to form a closer contact with the second contact 2 and improve the oil-proof effect.

Further, in order to improve the bonding strength between the sealing part 3 and the second contact 2 and prevent one of the sealing part 3 and the second contact 2 from being separated from the other due to displacement of one of the sealing part 3 and the second contact 2 during use, the periphery of the second contact 2 may be convexly provided with a groove adapted to the flange 3211. For example, in one embodiment of the invention, the flange 3211 is in the shape of a circular arc, and then the groove is also in the shape of a circular arc. In this way, the flange 3211 may be completely placed in the groove, so that the second sealing ring 32 is inserted into the second contact 2. On the one hand, the bonding strength between the second sealing ring 32 and the second contact 2 can be enhanced, and on the other hand, even if tobacco tar leaks from the gap between the second sealing ring 32 and the second contact 2, the leaked tobacco tar can be received through the flange 3211, and the tobacco tar can flow into the sealing layer encircled by the second sealing ring 32 to prevent the tobacco tar from continuing to leak downwards, thereby achieving the purpose of oil prevention. Preferably, the flange 3211 is in interference fit with the groove to prevent the flange 3211 from coming out of the groove.

In this embodiment, as shown in FIG. 2 and FIG. 6, the second contact 2 comprises a contact cap 21 and a contact post 22. One end of the contact cap 21 extends out of the through hole 421 and is exposed in the installation hole 13 for electrical contact of an external load, and the other end thereof is received in the through hole 421 and is sleeved on the periphery of the contact post 22. The contact cap 21 has a circular boss structure and comprises a first cylinder 211 and a second cylinder 212. The first cylinder 211 is placed on the second cylinder 212, and the diameter of the first cylinder 211 is smaller than the diameter of the second cylinder 212. The side of the second cylinder 212 far away from the first cylinder 211 is provided with a receiving hole (not shown) and is sleeved on the periphery of the contact post 22 through the receiving hole. The contact post 22 is provided with a step 221. The side of the second cylinder 212 provided with the receiving hole encloses the groove 26 with the step 221 and the contact post 22. When the flange 3211 is placed in the groove 26, the flange 3211 is clamped between the second cylinder 212 and the step 221 to play a role in fastening the flange 3211.

Further, as shown in FIG. 3, the conductive contact 100 further comprises an elastic part 23 received in the receiving groove 201, and the elastic part 23 is positioned below the contact post 22 with one end elastically abutting against the contact post 22 and the other end elastically abutting against the inner wall of the receiving groove 201. That is, the bottom end of the second contact 2 is only supported by the resilient force from the elastic part 23, and moves up and down under the action of the elastic part 23 in the process of pressing/releasing the contact cap 21, thereby ensuring reliable electrical contact with the external load.

In this embodiment, the elastic part 23 is a spring. Preferably, the elastic part 23 is a conical spring, wherein the wide end of the elastic part 23 elastically abuts against the bottom wall of the receiving groove 201, and the narrow end of the elastic part 23 elastically abuts against the second contact 2, This helps the elastic part 23 to reduce the deviation in the radial direction during compression/resilience, thereby ensuring that the second contact 2 can move up and down in the axial direction. Further, the end of the contact post 22 abutting against the elastic part 23 may be further provided with a contact plate 24 adapted to the narrow end. Preferably, the diameter of the contact plate 24 is slightly larger than the diameter of the narrow end. Further, a terminal 25 may also extend from one end of the contact plate 24, and the contact plate 24 is electrically connected to the battery component of the electronic cigarette body 200 through the terminal 25.

Further, in order to ensure that the elastic part 23 is compressed/rebounded only in the axial direction without deviation, the receiving groove 201 is internally provided with a guiding groove 202 adapted to the elastic part 23, and the elastic part 23 is placed in the guiding groove 202 with one end elastically abutting against the second contact 2 and the other end elastically abutting against the bottom wall of the guiding groove 202.

In this embodiment, as shown in FIG. 2 and FIG. 3, since the second contact 2 moves up and down in the axial direction under the action of the elastic part 23, in order to ensure that the second contact 2 is not separate from the second sealing ring 32 during the up and down movement and thus the sealing is not disabled, the inner wall of the groove 26 is provided with at least one positioning groove 2211, the flange 3211 is provided with at least one positioning projection 3212 adapted to the positioning groove 2211, and the positioning projection 3212 is placed in the positioning groove 2211 at a corresponding position to lock the relative position between the second contact 2 and the second sealing ring 32. Further, since the groove 26 is encircled by the side of the second cylinder 212 provided with the receiving hole, the step 221, and the contact post 22, the positioning groove 2211 may be provided on any of the second cylinder 212, the step 221, or the contact post 22. Preferably, the positioning groove 2211 is provided on the step 221, and the positioning groove 2211 is in interference fit with the positioning projection 3212 on the flange 3211 to prevent the second sealing ring 32 from coming out of the second contact 2.

In this embodiment, the first sealing ring 31 and the second sealing ring 32 are placed in the gap between the insulating part 4 and the first contact 1 and the gap between the insulating part 4 and the bottom wall of the receiving groove 201, respectively, and both elastically abut against the insulating part 4. In other words, the insulating part 4 is clamped between the first sealing ring 31 and the second sealing ring 32. In order to facilitate the assembly of the insulating part 4 and the sealing part 3 and improve the sealing performance of the sealing part 3, the insulating part 4 and the sealing part 3 may be made into an integrated structure in an integrated manner in practical applications. For example, the insulating part 4 and the sealing part 3 may be made into an integrated structure in a manner of double-shot molding. The sealing part 3 may be made of a soft rubber material, for example, silica gel, TPE|TPR (thermoplastic elastomer) soft rubber, PVC soft rubber, etc. The insulating part 4 is made of a hard rubber material, for example, ABS plastic and other engineering plastics.

Further, as shown in FIG. 4, in order to prevent the sealing part 3 from coming out of the insulating part 4 and increasing the bonding force there between, the sealing part 3 further comprises at least one connecting post 33, both ends of the connecting post 33 are vertically connected with the first sealing ring 31 and the second sealing ring 32, respectively. Correspondingly, the chassis 41 is provided with at least one through hole adapted to the connecting post 33, and each of the connecting posts 33 penetrates through the corresponding through hole and is connected with the first sealing ring 31 and the second sealing ring 32, respectively, so that the bonding strength between the sealing part 3 and the insulating part 4 can be effectively improved.

In this embodiment, as shown in FIG. 3 and FIG. 5, the insulating part 4 further comprises a connecting plate 43 extending from the chassis 41, the connecting plate 43 is provided with at least one first connecting hole 431, the electronic cigarette body 200 is provided with at least one second connecting hole corresponding to the first connecting hole 431. The connecting member sequentially passes through the first connecting hole 431 and the second connecting hole to fasten the connecting plate 43 to the electronic cigarette body 200, thereby fastening the insulating part 4 to the electronic cigarette body 200.

In this embodiment, as shown in FIG. 2, the first contact 1 comprises a contact body 11 and a sleeve 12. The contact body 11 is provided with the installation hole 13, and the sleeve 12 is sleeved on the periphery of the contact body 11. The inner wall of the installation hole 13 is provided with an internal thread through which an external load is installed. The bottom end of the contact body 11 elastically abuts against the first sealing ring 31 to prevent oil leakage from the first contact 1. In practical applications, a lead wire may be welded to the sleeve 12 or the contact body 11, which is electrically connected to the battery component in the electronic cigarette body 200 through the lead wire. Of course, a conductive sheet may be also sleeved on the periphery of the contact body 11, which is connected to the lead wire through the conductive sheet.
