When the heating element 3 needs to be taken out of the outer shell 4, force can be applied from the opening at one end of the outer shell 4 to push the two liquid guides, and the first liquid guide 1, the second liquid guide 2 and the heating element 3 are integrally pushed out from the opening at the other end of the outer shell 4, so that the clamping force of the two liquid guides on the heating element 3 is relieved, the heating element 3 is taken out, and the operation is more convenient; or, when the material of the outer shell 4 is silica gel or silicon rubber, since the outer shell 4 has a certain elasticity, the outer shell 4 can be peeled off from the two liquid conductors by pulling the outer shell 4, so that the clamping force of the two liquid conductors on the heating element 3 is released, the heating element 3 can be taken out, and the operation is convenient.

The atomizing core 10 provided by the present embodiment is an assembled atomizing core 10 rather than a sintered atomizing core 10, the heating element 3 is sandwiched between two oppositely disposed liquid guiding bodies, and the outer shell 4 having a liquid inlet hole is sleeved outside the two liquid guiding bodies, so as to limit the heating element 3 and the two liquid guiding bodies in the outer shell 4, thereby forming an assembled atomizing core 10 with a stable structure, compared with the sintered atomizing core 10, the atomizing core 10 provided by the present embodiment of the present invention is not co-fired with the heating element 3 and the liquid guiding bodies, that is, the heating element 3 and the liquid guiding bodies are not fixed together by sintering, the resistance value of the heating element 3 is selected and obtained, therefore, the problem of the resistance value change caused by oxidation of the heating element 3 can be effectively avoided, better temperature control performance can be obtained, and, moreover, since the heating element 3 is sandwiched between the two liquid guiding bodies by a mechanical assembly method, the heating element 3 can be released from the clamping force of the two liquid guiding bodies 3 (or at least one liquid guiding body 4 is removed from the outer shell 4, the heating element 3 can be easily released), so that the heating element 3 can be separated from the clamping force, thereby facilitating the use of the two liquid guiding bodies 10 after use.

Further, with continued reference to fig. 1-4, in an exemplary embodiment of the present invention, at least one second vent groove 21 for allowing the smoke to flow out is formed on the surface of the second liquid guiding body 2 contacting with the heating body 3. So set up for heat-generating body 3 leads the adsorbed atomizing liquid of liquid to two and heats the produced smog after the atomizing, except can flowing out through first air channel 11, still can flow out through second air channel 21, thereby is favorable to further improving atomizing core 10's play cigarette smoothness nature. In a specific implementation, the number of the second air grooves 21 may be determined according to actual use requirements, generally speaking, the more the second air grooves 21 are provided, the better the smoothness of the smoke discharged from the atomizing core 10, but at the same time, the more the second air grooves 21 are provided, the smaller the contact area between the second liquid guide 2 and the heating element 3 is, the smaller the amount of the atomized liquid conducted from the second liquid guide 2 to the heating element 3 is, and the smaller the amount of the smoke generated during the heating process of the heating element 3. For example, as shown in fig. 1 to 3, in some embodiments, the second vent grooves 21 are provided in plural numbers (in the figures, 6 second vent grooves 21 are schematically provided on the second liquid guiding body 2), each second vent groove 21 extends in the direction of the two hollow ends of the outer housing 4, and the second vent grooves 21 are spaced and arranged in parallel. In addition, in some preferred embodiments, can stagger the setting each other with first air channel 11 and second air channel 21, so, for setting up each first air channel 11 and each second air channel 21 one-to-one, can guarantee that every position homoenergetic of heat-generating body 3 contacts corresponding drain, make every position homoenergetic of heat-generating body 3 receive the atomized liquid and carry out the heating atomization, and every position of heat-generating body 3 heats the produced smog homoenergetic of atomizing and discharges smoothly through corresponding air channel, thereby both guaranteed atomizing core 10 can produce sufficient smog volume, guaranteed atomizing core 10's play cigarette smoothness nature again, make atomizing core 10's play cigarette volume and play cigarette smoothness can obtain a fine compromise.

In this embodiment, it should be noted that, in practical implementation, the cross-sectional shapes of the first ventilation groove 11 and the second ventilation groove 21 can be flexibly set according to practical use requirements, and for example, the cross-sectional shapes may be rectangular, triangular, trapezoidal, semicircular, and the like, as long as the smoothness of smoke emission of the atomizing core 10 can be improved, and this embodiment is not particularly limited. Illustratively, as shown in fig. 3, the cross-sectional shapes of the first vent groove 11 and the second vent groove 21 are both rectangular.
