The technical solution adopted in "Hair Dryer and Blowing and Suction Device" is: a hair dryer, comprising a shell, wherein an air inlet is arranged on the shell, and air enters from the air inlet; A motor located inside the casing; An axial flow fan driven by the motor rotates along a fan axis and generates airflow; A blowing pipe connected to the shell and equipped with an air outlet, from which the airflow is blown out; A culvert is used to guide the airflow towards the air outlet; The shell and the blowing duct have an airflow channel, which includes an upstream area from the air inlet to the axial fan and a downstream area from the axial fan to the air outlet. The motor is located in the upstream area, and the duct is located in the downstream area.
Preferably, the air inlet, the motor, the axial fan, and the culvert are arranged longitudinally in sequence.
Preferably, the projection of the air inlet and the air outlet on a plane perpendicular to the fan axis is at least partially coincident.
Preferably, the airflow channel includes several airflow surfaces perpendicular to the direction of airflow flow, and the minimum airflow surface area in the upstream area is greater than the rotational surface area formed by the rotation of the blades of the axial flow fan.
Preferably, the upstream area includes a surrounding area set around the motor, and the ratio of the minimum area of the surrounding area to the area of the rotating surface formed by the rotation of the blades of the axial flow fan ranges from 1.5 to 2.5.
Preferably, the upstream region includes a transition region longitudinally located between the motor and the axial fan, and the inner wall of the shell where the transition region is located is a smooth surface.
Preferably, the ratio of the minimum area of the transition area to the area of the rotating surface formed by the rotation of the blades of the axial flow fan ranges from 1.5 to 2.5.
Preferably, the longitudinal distance between the axial fan and the motor is 25 millimeters.
