Abstract: An electromagnetic heating element includes: a tubular side wall; and a bottom wall disposed at an end of the tubular side wall in an axial direction. The tubular side wall and the bottom wall define a vaporization cavity. The tubular side wall and/or the bottom wall is provided with a through hole connecting the vaporization cavity to an outside.

Abstract: An aerosol-generating apparatus is provided. The aerosol-generating apparatus includes a heating base and a heating member. The heating base has a heating cavity, the heating member is configured to accommodate and heat an aerosol-generating substrate, the heating member is disposed in the heating cavity. The heating member includes a first sidewall, a first airflow channel is formed between the first sidewall and the inner surface of the heating cavity. A protrusion is disposed on an inner surface of the first sidewall, the protrusion makes a second airflow channel formed between the first sidewall and the aerosol-generating substrate, and both the first airflow channel and the second airflow channel are led from the outside of the aerosol-generating apparatus to the bottom of the heating cavity.

Abstract: An aerosol-forming apparatus includes: a vaporization assembly having: a liquid storage body with a liquid storage vaporization cavity for storing aerosol-forming substrate; and a heating body for heating and vaporizing the aerosol-forming substrate when power is applied. The heating body is slidably connected to the liquid storage body between a first location and a second location. The heating body is located outside the aerosol-forming substrate when the heating body is located at the first location. At least a part of the heating body protrudes into the aerosol-forming substrate when the heating body is located at the second location.

Abstract: A heating body detachably disposed in a aerosol-generation device is disclosed. The heating body includes a housing and a heating element. The housing is configured to accommodate an aerosol-generation substrate and includes an air inlet hole and an air outlet hole. The heating element is disposed in the housing and configured to generate heat through an eddy current in an alternating magnetic field. The aerosol-generation substrate generates an aerosol in response to the heat from the heating element.

Abstract: An electromagnetic induction heating element includes: a substrate; an insulating layer arranged on the substrate; and a temperature sensing layer arranged on the insulating layer. A material of the substrate is a metal elementary substance or alloy. The temperature sensing layer includes a temperature measuring circuit formed by sintering resistance slurry.

Abstract: An electromagnetic heating assembly includes: a fixing tube with two run-through ends for fixing an aerosol-forming substrate; a heating body at least partially extending from a first end of the fixing tube into the fixing tube and inserted into the aerosol-forming substrate in the fixing tube; and an induction coil sleeved on a periphery of the fixing tube for generating electromagnetic induction under an energized state so as to cause the heating body to heat. A ratio of a total height of the induction coil to a depth by which the heating body is inserted into the aerosol-forming substrate in the fixing tube ranges from 1:1 to 3:1.
