Electronic cigarette

An electronic cigarette, wherein:

• from a top to a bottom, the electronic cigarette comprises a mouth piece which is detachable, a top unit, an atomizer core, an electronic cigarette flavoring liquid tank and a power and control unit in sequence, wherein
• a bottom portion of the mouth piece is detachably connected to a top portion of the top unit;
• the top unit is connected to the mouth piece and the atomizer core, and has air inlets;
• wherein after entering the atomizer core through the air inlets, air flow is thoroughly mixed with atomizing steam in the atomizer core, then the air flow passes through the top unit, the mouth piece, and finally enters a mouth of a user;
• the atomizer core comprises a first shell;
• a slow penetration unit is closely pressed against an internal wall of the first shell;
• an electronic cigarette flavoring liquid inlet, which allows electronic cigarette flavoring liquid in the electronic cigarette flavoring liquid tank to enter the slow penetration unit, is provided on the first shell, and a heater is closely pressed against the slow penetration unit;
• a first electrode is provided at a bottom portion of the first shell, and a first insulating seal is provided between the first shell and the first electrode;
• a first pole of the heater is electrically contacted with the first electrode, a second pole of the heater is electrically contacted with the first shell;
• the bottom portion of the first shell is sealed through shrink fit of the first insulating seal, the first shell and the first electrode;
• a top portion of the first shell is opened, so as to form a hollow structure having a sealed bottom and an opened top;
• the atomizer core is loaded in from a top portion of the electronic cigarette flavoring liquid tank, and a top portion of the atomizer core is detachably connected to a bottom portion of the top unit;
• the electronic cigarette flavoring liquid tank comprises a second shell and a second electrode provided at a bottom portion of the second shell, wherein a second insulating seal is provided between the second shell and the second electrode, the bottom portion of the second shell is sealed through shrink fit of the second insulation seal, the second shell and the second electrode;
• a top portion of the second shell is opened, so as to form a hollow structure of the electronic cigarette flavoring liquid tank, which has a sealed bottom and an opened top;
• the electronic cigarette flavoring liquid tank is detachably connected to a top portion of the power and control unit;
• the power and control unit comprises a third shell and a third electrode provided at a top portion of the third shell, wherein a third insulating seal is provided between the third shell and the third electrode, for insulation sealing therebetween;
• a battery inside the power and control unit supplies the electronic cigarette, and outputs or cuts off a current through a power switch;
• after assembling, the first pole of the heater of the atomizer core is connected to a first pole of the battery inside the power and control unit through the first electrode, the second electrode and the third electrode in sequence;
• the second pole of the heater of the atomizer core is connected to a second pole of the battery inside the power and control unit through the first shell, the second shell and the third shell in sequence;
• complete current loops are formed at each part;
• the heater of the atomizer core is supplied by the power and control unit for atomizing the electronic cigarette flavoring liquid.
