Atomizing core, atomizer, electronic cigarette, and assembly method

An atomizing core for atomizing an atomizing substrate to form an aerosol, comprising:

• an atomizing core housing defining an airflow inlet, an airflow outlet, an accommodating space between the airflow inlet and the airflow outlet, and at least one atomizing substrate inlet in communication with the accommodating space;
• an atomizing seat arranged in the accommodating space and defining an atomizing channel for being in communication with the airflow inlet and the airflow outlet, and at least one opening for communicating the at least one atomizing substrate inlet with the atomizing channel;
• and
• at least one heating sheet arranged in the atomizing channel and at least partially opposite one or more of the at least one opening, respectively;
• wherein an absorbing material for the atomizing substrate is arranged in each of the at least one opening.
