In order to make the technical solution of the present invention better understood, the technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

The embodiment of the present invention provides a ceramic atomizing core, as shown in fig. 1 and 6, the ceramic atomizing core includes a ceramic body 100 and a heat generating portion 200; the heat generating part 200 is disposed on the bottom outer surface of the ceramic body 100; ceramic body 100 includes oil storage through-hole 101 and at least one oil absorption terminal surface 102, oil absorption terminal surface 102 is located ceramic body 100's tip, oil storage through-hole 101 run through ceramic body 100, the opening of oil storage through-hole 101 is located on the oil absorption terminal surface 102, the topside of oil storage through-hole 101 is in projection length L1 on the base of oil storage through-hole 101 is less than base length L2 of oil storage through-hole 101.

It will be appreciated that the working principle of the ceramic atomizing core is substantially as follows: ceramic body 100 is made for porous ceramic material, oil absorption terminal surface 102 is ceramic body 100's terminal surface, this oil absorption terminal surface 102 can contact with the tobacco tar, this ceramic body 100 on the one hand contacts with the tobacco tar through oil absorption terminal surface 102, permeate the inside ceramic body 100 with the tobacco tar, on the other hand makes the tobacco tar flow in oil storage through-hole 101 through the opening of oil storage through-hole 101, the tobacco tar can permeate to ceramic body 100 inside from the inner wall of oil storage through-hole 101, the tobacco tar permeates to ceramic body 100's inside back, form aerosol after the heating of the portion 200 that generates heat, and the bubble that the tobacco tar formed in oil storage through-hole 101 can come up in the oil storage passageway because density is less, the bubble comes up to the top of oil storage through-hole 101, because the topside length of oil storage through-hole 101 is shorter, the top coverage area of oil storage through-hole 101 is little, the bubble runs out more easily. This application removes the back with its both ends apex angle on traditional oil storage through-hole 101's basis, has reduced the center of oil storage through-hole 101 and the shortest distance of external intercommunication, and the bubble can run out from oil storage through-hole 101 more fast, is difficult for forming in oil storage through-hole 101 and gathers.

Compared with the prior art, the ceramic atomizing core at least has the following beneficial effects: the length of the projection of the top edge of the oil storage through hole 101 on the bottom edge of the oil storage through hole 101 (namely, the length of L1 in figures 3 and 4) is smaller than the length of the bottom edge of the oil storage through hole 101 (namely, the length of L2 in figures 3 and 4), so that the length of the top edge of the oil storage through hole 101 is shorter, the top covering area of the inner wall of the oil storage through hole 101 is reduced, and the distance between the center of the oil storage through hole 101 and the outside is shortened so that bubbles overflow. The application avoids the problem that bubbles are not easy to discharge due to the overlong oil storage through hole 101, so that the risk of dry burning caused by bubble aggregation is caused, and the safety and the practicability of the product are improved.

Further, the ratio of the projection length L1 of the top edge of the oil storage through hole 101 on the bottom edge of the oil storage through hole 101 to the length L2 of the bottom edge of the oil storage through hole 101 is not more than 9: 10. it should be understood that the present invention is limited only by the ratio of the projected length L1 of the top side of the oil storage through hole 101 to the length L2 of the bottom side of the oil storage through hole 101, and the shape of the oil storage through hole 101 is not particularly limited.

For example, in one embodiment, as shown in fig. 3, the top edge (ab) and the bottom edge (cd) of the oil storing through hole 101 are both parallel and parallel to the horizontal plane, the hole diameter of the oil storing through hole 101 in the length direction thereof is equal, L1 is equivalent to the length of the top edge (ab) of the oil storing through hole 101, and L2 is equivalent to the length of the bottom edge (cd) of the oil storing through hole 101, that is, the ratio of the length of the top edge of the oil storing through hole 101 to the length of the bottom edge of the oil storing through hole 101 is not less than 9: 10.

In one embodiment, as shown in fig. 4, the top side (ab) and the bottom side (cd) of the oil storing through hole 101 are not parallel to the horizontal plane, and the aperture of the oil storing through hole 101 gradually increases along the length direction of the oil storing through hole 101, L1 is the length of the projection (a 'b') from the top side to the bottom side of the oil storing through hole 101, and L2 is the length of the bottom side (cd).
