The second conductive sheet 22 and the first conductive sheet 10 function as a lead wire, and the metal sponge 9 is connected in series with the power supply 23, and the indicator light 4 is also connected in series therein.

In the specific implementation:

the user firstly draws the movable tobacco rod 3 out, the first conducting strip 10 is contacted with the second conducting strip 22, the circuit is communicated, the indicator lamp 4 is lightened, and the metal sponge 9 generates heat. The movable tobacco rod 3 drives the first piston 16 to move outwards, and the first piston 16 sucks out tobacco tar in the cartridge 26 through the piston cylinder 15, the first communicating hole 25 and the second communicating hole 28.

After the user loosens the movable tobacco rod 3, the movable tobacco rod 3 is gradually reset under the action of the reset elastic part 20, and the first piston 16 presses the tobacco tar into the oil storage cabin 8 through the capillary oil delivery pipe. Because the internal diameter of the capillary oil conveying pipe is only 0.2mm, the oil can not be quickly discharged or returned by the short force application and air pressure from the outside, the oil can be continuously discharged and returned only under the action of long-time force application or the surface tension of liquid in the oil conveying pipe, and the influence of the external air pressure and vibration on oil conveying is avoided. After the tobacco tar enters the oil storage cabin 8, the tobacco tar generates gaseous smoke through the atomization effect of the metal sponge 9, the smoke enters the tobacco cabin 12 again, and the user sucks the smoke out when smoking the cigarette holder 6. When the movable cigarette body moves to the shortest position, the second conducting plate 22 contacts with the power-off plate 11, and because the power-off plate 11 is arched outwards, when the two contact, the first conducting plate 10 below the power-off plate 11 moves inwards for a certain distance, so that the first conducting plate 10 and the second conducting plate 22 are separated, and the circuit is disconnected.
