1. An air intake system of a heating and ventilation air conditioner for a vehicle, the air intake system comprising:
an air intake housing;
a volute, with a fan assembly accommodated in the volute, used for sucking in an airflow to cause the airflow to enter the volute via the air intake housing; and
a filter, which is arranged adjacent to an air inlet of the volute, and is used for filtering the airflow,
wherein the volute is provided with a support part that protrudes by a predetermined height from the air inlet so as to support the filter,
wherein the support part comprises an annular structure and is connected to the air inlet by means of a connecting rib,
wherein a corner part between the connecting rib and the air inlet is a smooth transition part, so as to diminish disturbance to the airflow by the corner part, and
wherein an edge of the air inlet comprises a curled side that extends inward and in a downstream direction of the airflow, and the connecting rib is connected to the curled side.
