Air inlet noise reduction type high-pressure air blower

The utility model discloses an air inlet noise reduction type high-pressure air blower which comprises a support, a driving motor and a high-pressure air blower body are installed on the support, thehigh-pressure air blower body comprises an outer shell and an impeller assembly, a transmission shaft of the driving motor is connected with the impeller assembly, an air inlet and an air outlet are formed in the outer shell, and an inlet assembly is arranged on the air inlet. The fixing plate is additionally arranged at the air inlet, so that the air inlet distance is prolonged, and huge tangential noise caused by the fact that external airflow directly enters the fan is avoided; besides, an axial air inlet vortex is formed at the first tip, a good airflow guiding effect is achieved, the airinlet effect is improved, a radial centrifugal vortex is formed at the second tip, airflow entering the air blower is converted into the radial direction from the axial direction under the action of the radial centrifugal vort
