Similarly, the micro grooves 2101 are linear micro grooves. The extending direction of the micro grooves 2101 may be set at a predetermined angle with respect to the longitudinal direction of the heating element 200.

Further, in this embodiment, the cross section of the micro groove 2101 is triangular, rectangular, trapezoidal, semicircular or oval, and the depth of the micro groove 2101 may be in the range of 5um-15um, for example, the depth of the micro groove 2101 may be set to 5um, 10um or 15um.

The scheme can ensure that the local resistance change of the heating element 200 is not too large, so that the uniformity of local heat flow of the heating element 200 can be improved, and the heating element 200 is not easy to blow in the heating and atomizing process. Meanwhile, the depth of the micro groove 2101 is controlled within the range of 5um-15um, so that the separation speed of bubbles formed after atomization of the atomized liquid is obvious, and the effect of controlling the boiling characteristic in the atomization process and controlling the mechanism of aerosol formation is achieved.

In this embodiment, the width of the micro groove 2101 may be in the range of 5um to 30um, and a plurality of parallel micro grooves 2101 may be formed in the micro groove 210 at intervals, where the width of each micro groove 210 may be 3 to 5 times the width of the micro groove 2101, and the interval between two adjacent micro grooves 210 may be 5 to 8 times the width of the micro groove 210.

Wherein, the surface of the heating wire 300 is smooth and has no micro-groove structure; therefore, when the heating wire 300 is used to heat and atomize the atomized liquid, the volume difference of the bubbles formed after the atomized liquid is atomized is large, and the bubble distribution is uneven.

Fig. 16a to 16c are schematic views showing changes in atomization effect when heating and atomizing are performed by using a heating element in the prior art, as shown in fig. 16a to 16 c.

When the heating element 200 provided by the application is used for heating and atomizing, bubbles can be formed in the position of the micro groove 2101 by gas formed after atomization, and the bubbles gradually get away from the micro groove 2101 to be released after gradually growing up, so that the positions of the bubbles which are separated from the micro groove 2101 are fixed, and therefore, the distribution of the released bubbles can be more uniform by arranging a plurality of micro groove parts 210 which are arranged at intervals on the heating element 200; in addition, the bubbles are more easily separated from the surface of the liquid film of the atomized liquid in the micro-groove 2101, so that the volume of the bubbles can be controlled within a certain range, and the taste in the atomization process can be effectively realized.

Fig. 20a to 20c are schematic diagrams showing changes in atomization effect when the heating element provided by the application is used for heating and atomizing, as shown in fig. 20a to 20 c.
