The embodiment of the utility model discloses a powerful toy blower, comprising a housing, a fan and a motor. Application of Bernoulli's Principle enhances the efficiency of air flow. The housing adopts centrifugal design, with which the fan shall easily rotate at high speeds and air resistance to the fan will be much lower, leading to higher fan capacity. On the housing shell near a motor fixing socket, two air inlets are disposed for efficient heat dissipation and sufficient air flow so that the service life of the blower can be extended. The fan is shaped based on geometric modeling. The fan blades are tangent to the annular hub and perpendicular to the periphery of the rotating plate. Also, the edge of each blade at the periphery is vertical to the rotating plate, so as to reduce air leakage and avoid air backflow. A motor mounting socket is disposed within the center top of the rotating plate, which not only enhances operation stability and avoid unnecessary vibration but also reduces the size of the housing and the cost of production.
A powerful toy blower comprises a housing having an air outlet, a fan disposed in the housing, and a motor. The housing adopts a centrifugal design, comprising an upper and a lower half shells. Inside the housing are a fan chamber and an air flow channel. The fan is disposed in the said fan chamber. A motor fixing socket is located on the said upper half shell, corresponding to the motor mounting socket on the rotating plate of the fan. The motor is disposed within the motor mounting socket through the motor fixing socket.
