In order to enable the cigarette holder to be inserted into the atomization shell reversely and simultaneously seal the cigarette outlet passage, an opening of the cigarette outlet channel 3-2 on the upper surface of the air guide piece 3 deviates from the center, a cigarette outlet blocking table 10-2 and a smoke sucking through hole 10-3 correspondingly communicated with the opening of the cigarette outlet channel 3-2 on the upper surface of the air guide piece 3 are arranged below the cigarette holder 10, and the cigarette outlet blocking table 10-2 is inserted reversely to block the opening of the cigarette outlet channel 3-2 on the upper surface of the air guide piece 3. The cigarette holder of this embodiment adopts reverse plug-in closed gas circuit of upset, of course also can adopt the mode of rotatory closed gas circuit.

In order to save cost, reduce volume and facilitate miniaturization of the electronic cigarette, the oil storage cavity of the embodiment is integrally formed at the inner side of the atomization shell 1, and the oil storage cavity 1-4 is provided with an oil filling hole which is detachably sealed by the oil seal cover 1-41. The top of the oil seal cover is magnetically connected with the upper cover 19.

As shown in fig. 4, the housing 2 includes a bottom open-ended accommodating housing 21, a bottom cover 22 detachably engaged with the bottom open-ended accommodating housing 21, a rebound spring 23 is disposed at a lower portion of an inner left side of the accommodating housing 21, one end of the rebound spring 23 is fixed at an inner side of a lower portion of the accommodating housing 21, the other end is in a free state, two ends of the bottom cover 22 are respectively disposed at left and right sides of the bottom cover 22, a spring slot 231 correspondingly engaged with the bottom cover button 222 at one end of the bottom cover is disposed at a free end of the rebound spring 23, and a housing recess (labeled in the drawing) correspondingly engaged with the bottom cover button 222 at the other end of the bottom cover is disposed at a side opposite to the side where the rebound spring 23 is disposed at the bottom of the accommodating housing 21. The shell adopts the rebound fastening mode of the rebound reed, so that a reserved space is not needed at the side edge of the battery in the shell, and only the thin rebound reed 23 is required to be inserted or fixed, thereby greatly reducing the volume of the electronic cigarette, being beneficial to the miniaturization of the electronic cigarette and improving the battery capacity. The buckling is movable buckling, and after buckling, the buckling is stable and good due to the elastic action of the rebound reed. When the spring is unbuckled, the bottom cover is only pushed, the elasticity of the rebound reed is overcome, and the spring is released, so that the spring is convenient to assemble, and no tool assistance is needed. Meanwhile, the problem that part of shell materials cannot be processed with sliding grooves is solved, and the electronic cigarette is simple in structure, humanized, low in cost and particularly suitable for small electronic cigarettes.
