A fresh air module and an air conditioner are provided. The fresh air module has a housing and a fan assembly. The housing has a fresh air duct inside the housing. The fan assembly has a motor and a wind wheel disposed in the fresh air duct. The motor has a motor body and a motor shaft. The motor shaft drives the wind wheel to rotate, so as to guide airflow to flow through the fresh air duct. The motor cover is arranged on the housing and outside of the fresh air duct. A motor accommodating cavity is defined in the motor cover and accommodates the motor body. A partition member is formed between the motor accommodating cavity and the fresh air duct to separate the motor accommodating cavity from the fresh air duct. The motor shaft penetrates through the partition to connect with the wind wheel.
