First Embodiment

As shown inFIG. 3, when the cigarette holder3is connected with one end of the cigarette body part2, the cell part1is detachably installed on the other end of the cigarette body part2.

The cigarette body part2is further equipped with a top electrode14installed on a back-end of the heating element7, and the through hole17is provided on the top electrode14.

The cross-section of the electronic smoking device is circular.

To improve the safety, the outside of the top electrode14is sleeved with an insulation sleeve21.

Specifically, the insulation sleeve21can be consisted of rubber, resin, silica gel and the like.

It is to be understood that the mode to fix the top electrode14in the cigarette body part2is not defined specially. Specifically, the mode to fix the top electrode14in the cigarette body part2in the present invention is as follows: an end of the cigarette body part2is equipped with a first copper element30, the insulation sleeve21is then clamped inside the first copper element3, and the top electrode14is subsequently clamped inside the insulation sleeve21so as to achieve a permanent connection between the top electrode14and cigarette body part2.

The insulation sleeve21is in a pressed state at this time.

As shown inFIG. 2, the cell part1comprises a lower electrode15which is permanently installed on its front end.

To improve the safety, the outside of the lower electrode15is sleeved with an insulation sleeve20.

Specifically, the insulation sleeve20can be consisted of rubber, resin, silica gel and the like.

It is to be understood that the mode to fix the lower electrode15in the cigarette body part2is not defined specially. Specifically, the fixing mode in the present invention is as follows: the insulation sleeve20is clamped inside the cell part1, and the lower electrode15is subsequently clamped inside the insulation sleeve20so as to fix the lower electrode15within the cell part1.

The insulation sleeve20is in a pressed state at this time.

The connection mode between the cell part1and cigarette body part2has no specific limitation, which can be achieved by interference fit, pin connection, clamp fit, screw-thread fit and the like.

Preferably, the mode of screw-thread fit is employed in the present invention, so that a detachable structure is formed by the cell part1and the cigarette body part2.

Its specific structure is as follows: the end of the cell part1is equipped with an external thread, and the first copper element30of the cigarette body part2is equipped with an inner thread simultaneously; in this way, the outer thread is screwed with the inner thread so as to achieve the connection of the cigarette body part2and cell part1.

When the cell part1and the cigarette body part2are in the state of connection, the top electrode14and the lower electrode15contact with each other for ensuring the connection between the electrodes.

The electronic smoking device also comprises a sealing component10which is arranged between the cell part1and the cigarette body part2. Herein, the cigarette body part2and the cell part1are sealed by the sealing component10.

It is to be understood that the sealing between the cigarette body part2and the cell part1can be achieved by the following three ways. However, it is not limited to these ways.

Specifically, as shown inFIG. 2andFIG. 3, the lower electrode15has a cavity16in a first implementation.

When the cell part1is connected with the cigarette body part2, two ends of the sealing component10are respectively inserted into the through hole17and the cavity16.

Since the sealing component10is inserted into the through hole17and the cavity16, the sealing between the cell part1and the cigarette body part2can be achieved.

The connection mode of the sealing component10and the through hole17is interference fit at this time.

Further, as shown inFIG. 4, the lower electrode15is planar in a second implementation.

One end of the sealing component10is inserted into the through hole17, and its other end presses against the lower electrode15. Herein, the sealing of the cigarette body part2and the cell part1is achieved by such structure.

The connection mode of the sealing component10and the through hole17is interference fit at this time.

Further, as shown inFIG. 5, the lower electrode15has a cavity16in a third implementation.

One end of the sealing component10is inserted into the cavity16, and its other end presses against the end of the top electrode14. Herein the sealing component can completely block an opening of the through hole17, in which case the sealing of the cigarette body part2and the cell part1is achieved by such structure.

The following beneficial effects can be achieved using the seal structure described above.

On one hand, hot air in the cigarette body part2does not flow to the cell part1during smoking so as to prevent the cell with sensitivity to heat from damage. On the other hand, such structure can prevent the loss of heating heat in the cigarette body part2during smoking.

The cigarette holder3is installed on one end of the cigarette body part2.

The cigarette holder3and the cigarette body part2are detachable with respect to each other.

The cigarette holder3is consisted of soft material. For example, it can be consisted by rubber, resin, silica gel and the like.

It is to be understood that the connection mode of the cigarette holder is not defined specially. Specifically, a front end of the cigarette body part2is permanently installed with a hollow second copper element13. The cigarette holder3is combined with the cigarette body part2by clamping the cigarette holder3into the hollow part of the second copper element13. Wherein, the inner diameter of the cigarette holder3is slightly larger than that of the second copper element13.

In this way, the cigarette holder3and the cigarette body part2as well as the cell part1and the cigarette body part2are structures that can be installed detachably, so that when loading the tobacco, the cell part1and the cigarette body part2can be unscrewed directly to load the tobacco and tobacco rod into the connecting structure formed by the through hole17and the tobacco container5.

In the process of cleaning the tobacco and the tobacco rod, the cigarette holder3and the cigarette body part2are separated while the cigarette body part2and the cell part1are unscrewed. Subsequently, a rod-like article which has a size comparable to that of a channel is stretched into the tobacco container5to clean the tobacco residue in the tobacco container5. In this way, it is ensured that no matter the tobacco rod or the hand-cut tobacco can be cleaned out quickly from the tobacco container5.

When the cigarette holder3and the cigarette body part2are not detachable, the cigarette holder3can be equipped with a through hole for loading or pushing out the tobacco rod and tobacco. When cleaning the tobacco or the tobacco rod, it is only needed to disassemble the cell part1and then draw out or remove the tobacco or the tobacco rod by the through hole of the cigarette holder3, the tobacco container5and the through hole17.

Herein, the cigarette holder3is connected to one end of the cigarette body part2, the cell part1is permanently installed on one side of the cigarette body part2, and the isolation region8is disposed between the cigarette body part2and the cell part1.

The present embodiment does not comprise the top electrode or the lower electrode. Instead, a PCB board is directly connected with the heating unit through a welding line provided in the isolation region8.

The isolation region8can be provided with some materials such as heat-protective cotton which are configured to isolate the cell part1and the cigarette body part2.

The electronic smoking device of the present embodiment also comprises a sealing component10. The sealing component10is installed on the other end of the cigarette body part2and further inserted into the through hole17.

In this embodiment, since the cell part1is permanently installed on one side of the cigarette body part2and is isolated by the isolation region8, the heat generated during smoking does not cause damage to the cell with sensitivity to heat.

The connection mode of the cigarette holder3and the cigarette body part2in this embodiment is the same as that in the embodiment.

When loading the tobacco, the sealing component10is removed directly from the cigarette body part2. After that, the tobacco and tobacco rod are loaded into the connecting structure formed between the through hole17and the tobacco container5.

In the process of cleaning the tobacco and the tobacco rod, the cigarette holder3and the cigarette body part2are separated and the sealing component10is taken out when the cigarette holder3and the cigarette body part are detachable structures, a rod-like article which has a size comparable to that of a channel is stretched into the tobacco container5to clean the tobacco residue. In this way, it is ensured that no matter the tobacco rod or the hand-cut tobacco can be cleaned out quickly from the tobacco container5.

When the cigarette holder3and the cigarette body part2are not detachable, the cigarette holder3can be equipped with a through hole for loading or pushing out the tobacco rod and the tobacco. When cleaning the tobacco or the tobacco rod, it is only needed to disassemble the sealing component10from the cigarette body part2and then draw out or remove the tobacco or the tobacco rod by the through hole of the cigarette holder3, the tobacco container5and the through hole17.
