The first conductor and the second conductor are both in the shape of a font, and are arranged in a staggered manner. They fit with the groove surface of the oil plug 4 or the suction nozzle cover 6 to form a staggered ring shape with openings. Obviously, the first conductor and the second conductor can also be in other suitable shapes, such as comb shape, zigzag shape, S shape, etc.

One of the functions of the oil blocking plug 4 is the same as that in the prior art, which is to separate the front half composed of the air pressure switch 2 and the battery 3 of the electronic cigarette from the atomizer 5 that is soaked in the electronic cigarette liquid during use. , in order to have better electrical work reliability, a ventilation hole 44 is provided in the middle.

Among them, the conductive layer on the inner surface of the elastic conductive ring can be coated with conductive plastic material or covered with thin aluminum foil, copper foil or metal materials with better conductivity and ductility. The elastic conductive ring is deformable plastic. material, which can be put on the groove in the middle of the oil plug 4 after being slightly expanded, and when its inner surface is not squeezed by external force, there is a gap of 0.01~0.5mm between the inner surface and the bottom surface 46 of the groove. The annular surface layer of the groove bottom 46 is affixed or printed with first conductors and second conductors shown in the enlarged area. The first conductors and the second conductors are staggered with each other on the expansion plane and are inseparable from each other. Direct conduction, the gap between them has good insulation under its working voltage, for example, a thin layer of polyester circuit board can be used to etch and then be reliably bonded in the groove. The first conductor 46a is reliably electrically connected to the heating circuit through the first connection electrode 42, and the second conductor 46b is reliably electrically connected to the heating circuit through the second connection electrode 45. The first connection electrode 42 has a connection end a', and the second conductor 46b is reliably electrically connected to the heating circuit through the second connection electrode 45. The connection electrode 45 has a connection terminal b'. When assembling the electronic cigarette, the first connecting electrode 42 and the second connecting electrode 45 are reliably connected to one pole of the battery 3; the connecting wire 43 has the same function and use method as the wire passing through the oil plug 4 in the prior art. When the elastic conductive ring is gently pressed by the smoker during use, the conductive layer on the inner surface of the elastic conductive ring contacts the concave At any point or multiple points on the first conductor 46a and the second conductor 46b of the groove bottom 46, the material of the conductive layer adheres to the gap between the first conductor 46a and the second conductor 46b, and its effect is equivalent Because a manual switch is connected in series in the circuit, the reliability of the electronic cigarette of the present invention is improved during use, storage and transportation.

In this embodiment, a disposable switch is added to the oil blocking plug 4 that can be pressed and squeezed in a certain manner by the user with appropriate strength during use, and is connected in real time with the air pressure connected in series in the heating circuit. The joint action of switch 2 forms a mechanism in which the heater in the atomizer 5 can only be triggered when the two switches are turned on together.
