Two electrode contacts 252 are spaced apart from each other on the base 25, the two electrode contacts 252 are connected to two ends of the heating element 232, and both of the electrode contacts 252 are electrically conductive, specifically, each of the electrode contacts 252 is made of an electrically conductive material such as iron, cobalt, or nickel, one of the electrode contacts 252 is used as a positive electrode contact, the other electrode contact 252 is used as a negative electrode contact, and when the atomizer 100 is mounted in place, the atomizer 100 is electrically connected to the battery device.

In the present embodiment, the upper cover 24, the atomizing housing 22 and the base 25 are independent elements, and the upper cover 24 and the atomizing housing 22, and the atomizing housing 22 and the base 25 can be detachably connected by means of clamping or inserting.

The battery device is detachably connected to the atomizer 100 by, but not limited to, snap-fit or plug-in connection or magnetic connection. After the battery device and the atomizer 100 are assembled in place, the positive electrode and the negative electrode on the battery device are electrically connected with the two electrode contact elements 252 respectively, so that the atomizer 100 can heat the tobacco juice under the electric driving action of the battery device and atomize the tobacco juice into smoke for a user to absorb.

In the present embodiment, the atomizer 100 has a first state and a second state, specifically, the first state is a state in which the atomizer 100 is not assembled with the battery device, and the second state is a state in which the atomizer 100 is electrically connected with the battery device after the atomizer 100 is assembled with the battery device in place.

In the first state of the atomizer 100, the lower end surface of the limiting protrusion 221 abuts against the upper end surface of the liquid sealing member 12, the liquid inlet hole 222 is shielded by the liquid sealing member 12, and the liquid sealing member 12 prevents the smoke liquid in the liquid storage cavity 11 from entering the atomization cavity 21 through the liquid inlet hole 222.

During the assembly process of the atomizer 100 and the battery device, the atomizer 100 is gradually switched from the first state to the second state, the battery device applies a downward-upward driving force to the base 25, the base 25 moves upward along the axial direction of the liquid sealing member 12 relative to the liquid sealing member 12, so that the atomizing housing 22 moves upward along the axial direction of the liquid sealing member 12 relative to the liquid sealing member 12, and the liquid inlet hole 222 can communicate with the liquid storage cavity 11 and the atomizing cavity 21. After the atomizer 100 is switched to the second state, the liquid inlet hole 222 communicates with the liquid storage chamber 11 and the atomization chamber 21, and the smoke liquid in the liquid storage chamber 11 enters the atomization chamber 21 through the liquid inlet hole 222.

After battery pack and atomizer 100 separation, the impetus that the battery pack applyed to base 25 disappears, because the existence of atomizing subassembly 20 self gravity, perhaps, through pulling base 25 downwards for base 25 is for a liquid sealing 12 along sealing 12 axial downstream, support when the lower terminal surface of spacing arch 221 and the up end of sealing 12, feed liquor hole 222 is shielded by sealing 12, the pore wall of mounting hole 121 shields feed liquor hole 222 promptly and makes feed liquor hole 222 stagger with stock solution chamber 11, atomizer 100 switches to first state from the second state.

When atomizer 100 and battery device are at the in-process of assembly, the battery device exerts the thrust from bottom to top to atomization component 20, is greater than the elasticity that elastic component 15 applyed atomization component 20 when the thrust, and elastic component 14 is compressed, and atomization component 20 is for sealing liquid spare 12 along the axial rebound of sealing liquid spare 12 for feed liquor hole 222 can communicate stock solution chamber 11 and atomization chamber 21, and atomizer 100 switches to the second state from the first state gradually. After the battery device and the atomizer 100 are separated, the pushing force applied to the base 25 by the battery device disappears, the elastic force applied to the atomizing assembly 20 by the elastic member 15 enables the atomizing assembly 20 to move downward along the axial direction of the liquid sealing member 12 relative to the liquid sealing member 12, when the lower end surface of the limiting protrusion 221 abuts against the upper end surface of the liquid sealing member 12, the liquid inlet hole 222 is shielded by the liquid sealing member 12, and the atomizer 100 is switched from the second state to the first state.

Specifically, the connecting portion 1311 is sleeved with the connecting ring 112, the ventilation member 14 is sleeved on the connecting ring 112, and an inner cavity of the ventilation member 14 is communicated with the smoke outlet 131. It is understood that the connection ring 112 may be made of a material with better sealing property such as silicon rubber or rubber, so as to further improve the air tightness between the upper cover 24 and the connection portion 1311.
