Composite type transverse flow fan

Abstract

A composite type transverse flow fan has a driving device and a fan blade module, which is attached to the driving device. The fan blade module further includes at least a rotating shaft, at least a fan blade part and at least a fan frame. The fan blade module further includes at least a rotating shaft, at least a fan blade part and at least a fan frame. The rotating shaft has a first coupling part and a second coupling part and both of the coupling parts detachably engage with each other. The fan blade part is attached to the rotating shaft. The fan frame is attached with the rotating shaft and provides a first joining part and a second joining part and both the joining parts detachably engage with each other. Once the driving device is in operation, the fan blade part is capable of rotates in the fan frame.

1 . A composite type transverse flow fan, comprising: 
 a driving device; and    a fan blade module, being attached to the driving device;    wherein the fan blade module further comprises    at least a rotating shaft, providing a first coupling part and a second coupling part and both of the coupling parts detachably engaging with each other;    at least a fan blade part, being attached to the rotating shaft; and    at least a fan frame, being attached with the rotating shaft and providing a first joining part and a second joining part and both the joining parts detachably engaging with each other.    whereby, once the driving device is in operation, the fan blade part is capable of rotates in the fan frame.    
   
   
       2 . The composite type transverse flow fan as defined in  claim 1 , wherein, the driving device is a motor.  
   
   
       3 . The composite type transverse flow fan as defined in  claim 1 , wherein, the fan blade part has a projection at the center thereof.  
   
   
       4 . The composite type transverse flow fan as defined in  claim 1 , wherein, bearings are disposed between the rotating shaft and the fan frame.
