Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization, in particular to a coaxial electronic atomization structure and an electronic atomization device. Background Art

[0002] For multi-flavor electronic atomization devices, one of the more common ones is that the atomization cores are arranged horizontally side by side in the atomization shell, and the other more common one is that the atomization cores are arranged vertically side by side in the atomization shell. For example, the Chinese utility model patent application with application number 201420240935.2 utilizes all the atomization chambers to be connected in sequence from top to bottom, so that the aerosol formed by the atomization chambers of each atomization core can be better mixed, and is therefore loved by more users. However, the lead of the heating element needs to pass through the atomization channel, which will cause the temperature of the lead to be high and affect the stable operation of the heating element; for example, the Chinese invention patent application with application number 201480073100.5 makes the first electrode structure and the second electrode structure both arranged in the smoke channel. In addition, the impact on the operating stability of the heating element is reduced, but when the two atomizer components are connected, they are directly connected by the first outer electrode of the laterally arranged first electrode structure and the second outer electrode of the laterally arranged second electrode structure. Since the first outer electrode of the first electrode structure and the second outer electrode of the second electrode structure are both laterally arranged, during the connection of the atomizer components, especially when the first outer electrode and the second outer electrode are threadedly connected, the threaded structure used as the electrode connection will be repeatedly worn, thereby causing the connection tightness of the threaded structure to decrease, thereby causing poor contact of the internal abutting electrodes, that is, causing poor contact of the first inner electrode and the second inner electrode, which will still affect the stable operation of the heating element.
