Abstract

The present disclosure relates to an atomizing core and an electronic atomizing device. The atomizing core includes: a base including an atomizing surface; and a heating element disposed on the base, and capable of atomizing liquid on the atomizing surface. The heating element includes a first surface that is in a thickness direction thereof and attached to the base. The heating element is provided with liquid guiding channels that are kept at a set distance from the first surface.

First claim

What is claimed is:

1. An atomizing core, comprising:
a base made of a porous ceramic material and comprising an atomizing surface; and
a heating element made of a metal alloy and disposed on the base, and capable of atomizing liquid on the atomizing surface;
wherein the heating element comprises a first surface that is in a thickness direction thereof and attached to the base, and the heating element is provided with liquid guiding channels that are in communication with outside the atomizing core and kept at a set distance from the first surface.

2. The atomizing core according to claim 1 , wherein the heating element further comprises a second surface that is spaced apart from the first surface in the thickness direction thereof, and the second surface and the first surface face oppositely; the liquid guiding channels extend through the second surface and are in communication with outside.

3. The atomizing core according to claim 2 , wherein the liquid guiding channels are micro holes, and a cross section of each of the micro holes is in a shape of circle, ellipse, rectangle, or regular polygon.

4. The atomizing core according to claim 3 , wherein the micro holes are arranged on at least part of the second surface along a plurality of rows of parallel lines.

5. The atomizing core according to claim 4 , wherein orthographic projections of any two adjacent rows of micro holes in a column direction do not completely overlap with each other; the column direction is a direction perpendicular to the parallel lines.

6. The atomizing core according to claim 2 , wherein the liquid guiding channels are elongated grooves; a plurality of the elongated grooves are arranged at intervals on at least part of the second surface.

7. The atomizing core according to claim 2 , wherein the heating element has a thickness is in a range from 10 μm to 150 μm; and a depth of the liquid guiding channel is in a range from 5 μm to 120 μm.

8. The atomizing core according to claim 1 , wherein the heating element further comprises a first side surface and a second side surface that are arranged oppositely; the first surface is connected between the first side surface and the second side surface; and both ends of the liquid guiding channel extend through the first side surface and the second side surface, respectively.

9. The atomizing core according to claim 1 , further comprising:
a first electrode connected to one end of the heating element; and
a second electrode connected to the other end of the heating element.

10. The atomizing core according to claim 1 , wherein the heating element is directly attached to the atomizing surface.

11. The atomizing core according to claim 1 , wherein the atomizing surface is provided with a groove, and the heating element is entirely or partially accommodated in the groove.

12. An electronic atomizing device, comprising the atomizing core according to claim 1 .
