The pushing spring in the embodiment is a light spring, and can be compressed by small pressure. The wallboard of the flue gas storage cavity in the embodiment is not provided with a one-way guide through hole, and is only used for collecting part of flue gas, and then the stored flue gas is pushed into the flue gas backflow channel through the pushing mechanism, and overflows from the flue gas overflow hole after entering the flue gas release cavity.

The electronic cigarette of the present invention may form a plurality of shapes of smoke, the smoke overflow hole 71 may be one or a plurality of, if one, the hole shape of the smoke overflow hole 71 is consistent with the external shape required to be formed by the smoke, for example, a heart-shaped smoke may be formed, as shown in fig. 5, i.e., the smoke overflow hole 71 is designed as a heart-shaped hole; or may be a pentagram-shaped smoke, as shown in fig. 6, i.e. the smoke escape holes 71 are designed as pentagonal holes. When the above-mentioned fume release cavity 7 is provided with a plurality of fume overflow holes, all the fume overflow holes 71 are densely distributed into a certain geometric shape or a non-geometric shape, i.e. the fume released by all the fume overflow holes 71 are combined to form fume with a specific external shape, such as a polygon, or a letter, a Chinese character or a picture.

In order to realize that the air inlet and the back flow smoke are independent and do not interfere with each other and increase the atomization effect of the electronic cigarette, the inner shell 3 for accommodating the battery 2 is arranged in the outer shell 1, the cavity enclosed by the inner shell 3 is used for accommodating the battery 2 and is used as a part of the air inlet channel 9, and a gap between the inner shell 3 and the outer shell 1 is used as a part of the smoke back flow channel 8. The atomizer 4 is internally provided with a flue gas pipe 41 communicated with the flue gas storage cavity 5, the flue gas pipe 41 is communicated with the air outlet hole 55 and is used as the other part of the flue gas reflux passage 8, the atomizer 4 can also be internally provided with an air pipe 42, and the air pipe 42 is communicated with the air inlet hole 54 and is used as the other part of the air inlet passage 9.
