As the air pressure within the seal cavity is reduced, the first seal 45 and the second seal 46 approach the interior of the seal cavity during the sealing process to avoid that under atmospheric pressure, the seal cavity volume is reduced and the air pressure is increased. In this embodiment, the side wall of the first mounting hole of the tobacco rod body 1 is provided with a first annular groove, and the first clamping portion 452 on the outer side of the first sealing member 45 is located in the first annular groove.

By means of the arrangement of the positions, the area of the elastic element 3 can be enlarged as much as possible, so that the influence on the air pressure of the sealing cavity is improved.
Since the cross-sectional shape of the tobacco rod body 1 is elliptical, the projection of the elastic member 3 on the plane of the second surface 21 is elliptical. By means of the arrangement of the shapes, the area of the elastic piece 3 can be enlarged as much as possible, so that the influence on the volume of the sealing cavity after the elastic piece 3 moves from the first state to the second state is improved.
The magnitude of the adsorption force generated by the pressure difference between the inside and outside of the sealed cavity is related to fig. 8 and 9, wherein in fig. 8, the elastic member 3 is in the first state, and in fig. 9, the elastic member 3 is in the second state. The derivation process is as follows:
principle reference gas state equation pv=nrt, where: p is the gas pressure, V is the gas volume, n is the amount of gaseous species, R is a constant, and T is a constant temperature. Since n and T are constant values in a room temperature sealed space, pv=nrt=constant value.
Namely P 0 V 0 ＝P 1 V 1 When the volume V of the closed space increases, the pressure P of the gas inside thereof decreases.
Compared with the existing common magnetic connection mode, the weight of the tobacco stem is about 30g, the magnet attraction force is about 150gf, and the current magnetic connection mode is converted into the connection mode of the embodiment, the combination force F=150gf (1.5N) of the tobacco cartridge body 2 and the tobacco stem body 1 is set, and the external atmospheric pressure is P 0 ＝1.0X10 5 pa, S is the projected area of the sealed cavity in the Z direction of about 0.6X10 -4 m 2 ，P 1 To seal the intra-cavity air pressure:
F＝P difference of difference S＝(P 0 -P 1 )S
Then there is P 0 -P 1 ＝F/S＝1.5/(0.6X10 -4 )＝2.5X10 4 pa
Namely (P) 0 -P 1 )/P 0 ＝2.5X10 4 /1.0X10 5 ＝1/4，P 0 /P 1 When the change of V is converted into 4/3, there is V 0 /V 1 =3/4, i.e. the volume change in the case is 1/4V 0 The pressure difference of the gas can reach the binding force same as the current magnetic attraction mode, and the cartridge body 2 and the tobacco rod body 1 are connected together.
