• a mixed-flow fan, arranged inside the housing;
• wherein the mixed-flow fan is configured to rotate around a rotation shaft to generate an airflow;
• a pressurizing member, disposed at a front of the mixed-flow fan and comprising a pressurizing seat, wherein the pressurizing seat comprises a pressurizing surface, and a radial size of at least part of the pressurizing surface gradually increases from the rear side to the front side;
• a cross-sectional area, in a radial direction of the housing, of a front end of the pressurizing seat is defined to enable the air inlet portion to be invisible by being shielded by the pressurizing seat, when viewing from the front side to the rear side.
