AIR NOZZLE, OVEN, AND COATING SYSTEM

This application provides an air nozzle, an oven, and a coating system, and pertains to the field of battery technologies. The air nozzle includes a housing and an airflow regulation apparatus. The housing includes a target air outlet and an air inlet, where air flow enters the housing through the air inlet and leaves the housing through the target air outlet. The airflow regulation apparatus is located at the target air outlet and is capable of moving between at least a first position and a second position, where the airflow regulation apparatus exerts a greater resistance against the air flow in the first position than the airflow regulation apparatus exerts against the air flow in the second position. When the airflow at the target air outlet needs to be reduced, the airflow regulation apparatus is regulated to the first position to increase the resistance against the air flow at the target air outlet, thereby reducing the airflow at the target air outlet. When the airflow at the target air outlet needs to be increased, the airflow regulation apparatus is regulated to the second position to reduce the resistance against the air flow at the target air outlet, thereby increasing the airflow at the target air outlet.
