During installation, the small end 132 penetrates through the avoiding hole 62 to be inserted into the power supply device, and then the snap ring 90 is clamped in the clamp slot 1322 to partially lock the small end 132 to the outer edge of the side, away from the large end 131, of the avoiding hole 62. The small end 132 does not need to be set longer to be inserted into the deeper avoidance hole 62, and the second electrode element 10 can be effectively prevented from sliding out and disengaging from the avoidance hole 62 under the action of elastic force.

Further, as shown in fig. 6, in the embodiment of the present invention, the insulating member 40 corresponds to the outer periphery of the big head end 131 is further provided with an adaptive avoiding groove 41, so that the big head end 131 can slide along the axial direction in the avoiding groove 41 under the action of external force. When the second electrode column slides along the mounting hole 71 under the action of external force, the avoiding groove 41 can have a positioning and guiding effect on the large head end 131, and the phenomenon that the second electrode piece is stressed unevenly and deviates is effectively prevented.

The utility model provides an electron cigarette, including electrode subassembly 100, this electrode subassembly 100's specific structure refers to above-mentioned embodiment, because the electron cigarette has adopted the whole technical scheme of above-mentioned all embodiments, consequently has all beneficial effects that the technical scheme of above-mentioned embodiment brought at least, and the repeated description is no longer given here.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
