Abstract

An electric cigarette has a heating coil (24) and a wick (20) which is in contact with the heating coil (24) at at least one point. The two ends (26, 28) of the heating coil (24) are arranged in an insulating body (30). A dimensionally stable tube socket (64) is fastened on the insulating body (30). A reservoir (60) which communicates with the wick (20), is arranged in a ring-shaped manner about the tube socket (64). The insulating body (30) and the reservoir (60) are surrounded by a tubular housing (70). According to the invention, each of the two ends (26, 28) of the heating coil (24) is clamped and contacted individually in the insulating body (30), in each case by means of one contact (40, 42). Such an electric cigarette can be produced by a first unit of wick (20), heating coil (24), insulating body (30) and contacts (40, 42) being produced and a second unit of tube socket (64) and reservoir (60) being produced. In the case of the second unit, the reservoir (60) can be filled with the desired liquid from the outside. The two assemblies are fastened together and are then slid into a housing (70). The production of the first and of the second units can be effected in a random order and independently of one another.

Claims

1. An electric cigarette (10)

having a heating coil (24),

having a wick (20) which is in contact with the heating coil (24) at at least one point,

having an insulating body (30, 30.2) in which the two ends (26, 28) of the heating coil (24) are arranged,

having a dimensionally stable tube socket (64) which is fastened on the insulating body (30, 30.2),

having a reservoir (60) which is arranged in a ring-shaped manner about the tube socket (64) and communicates with the wick (20),

having a tubular housing (70) which surrounds the insulating body (30, 30.2) and the reservoir (60),

wherein

each of the two ends (26, 28) of the heating coil (24) is clamped and contacted individually in the insulating body (30, 30.2) in each case by means of one contact (40, 42, 56).

2. The electric cigarette as claimed in claim 1,

wherein

a connection element (96), which is arranged on one end of the housing (70), is present,

electrical contacting exists between the connection element (96) and the contacts (56) of the insulating body (30.2).

3. The electric cigarette as claimed in claim 1,

wherein

4. The electric cigarette as claimed in claim 1,

wherein

the tube socket is fastened on the insulating body by means of at least one latching element.

5. The electric cigarette as claimed in claim 1,

wherein

the tube socket (64) comprises a collar (66) at its one end and is consequently realized as a small collar tube (62).

6. The electric cigarette as claimed in claim 5,

wherein

the collar (66) of the small collar tube (62) is arranged on the free end of the tube socket (64).

7. The electric cigarette as claimed in claim 1,

wherein
