Aerosol generating device and heating structure thereof

The utility model discloses an aerosol generating device and a heating structure thereof. The heating structure comprises a heating pipe, a heat exchanger and a heating body, the heat exchanger is provided with an air inlet hole, the air inlet hole is formed in the axial direction of the containing cavity, and the air inlet hole communicates with the containing cavity; the heating body is embedded in the heat exchanger, provided with a conductive connecting part extending out of the heating body and used for heating the heat exchanger. Due to the fact that the heating body is embedded in the heat exchanger, the heating body starts to heat from the interior of the heat exchanger, the temperature of the heat exchanger is gradually diffused from the interior to the center and the circumferential outer side, the heat exchanger is evenly heated, and then air passing through the heat exchanger can be evenly heated; and the heating body is embedded in the heat exchanger, heat energy generated by the heating body is
