Blowing and sucking machine

The invention discloses a blowing and sucking machine comprising a host chassis, a driving motor, a turbofan driven by the driving motor to rotate, and a damping component. A positioning bracket is fixed between the driving motor and the turbofan, and the positioning bracket is fixed to the host chassis. The damping component is arranged between the positioning bracket and the host chassis and/or the damping component is arranged between the driving motor and the host chassis. According to the blowing and sucking machine, as the damping component is arranged between the positioning bracket and the host chassis and/or between the driving motor and the host chassis, the environment of contact between the positioning bracket and the host chassis and/or between the driving motor and the host chassis can be improved, the vibration transferred by the driving motor to the host chassis is greatly reduced, and finally, the purpose of improving the phenomenon of hand numbness is achieved.
