Abstract

The present application discloses a heating element (62), a heating module (60), and an atomization assembly (100). The heating element (62) comprises: a heating body (61), which is wound around a central axis to form a hollow columnar structure and which is provided with a core heating area surrounding the central axis in a circumferential direction; and an intermediate support element (63), which passes through the core heating area in the circumferential direction around the central axis. When the heating element (62) is in a power-on state, the heating body (61) generates heat under the action of electric energy, and no current passes through the intermediate support element (63). According to the heating element (62), the intermediate support element (63) which passes through the core heating area in the circumferential direction effectively improves the structural strength of the heating element (62), so that the heating element (62) is not easily deformed, and the consistency of an aerosol generating device provided with the heating element (62) is consequently improved. Therefore, the inhalation lifespan of the aerosol generating device is increased and the taste stability thereof is improved, thus broadening the application scope of the heating element (62). Furthermore, since no current passes through the intermediate support element (63), no additional electric energy loss is caused, thereby ensuring the effective power supply of the core heating area, and ensuring the atomization efficiency of the aerosol generating device.

The heating body experiences the largest amount of heat at a position corresponding to the center of the electromagnetic heating coil, and the position is offset in the longitudinal direction from the longitudinal center of the accommodating cavity, which means that the position with the greatest amount of heat is located on one side of the longitudinal center of the accommodating cavity.

Abstract

An electromagnetic heating coil (20), a heating assembly (200), and an electronic atomization device (100). The electromagnetic heating coil (20) comprises a first spiral section (22) and a second spiral section (23) connected in sequence in an axial direction from one end to the other end.
