Band-type fan structure

Abstract

A band-type fan structure includes a transmission band body and multiple blades. The multiple blades are side by side disposed on the transmission band body along the surface of the transmission band body in parallel to each other. Each two adjacent blades define therebetween a flow way. When the transmission band body is continuously reciprocally moved, the blades are driven by the transmission band body to continuously reciprocally move to disturb the air in the flow ways so as to produce an air volume.

What is claimed is: 
     
         1 . A band-type fan structure comprising:
 a transmission band body, which is an elongated band body; and   multiple blades side by side disposed on the transmission band body along the transmission band body in parallel to each other, each two adjacent blades defining therebetween a flow way, when the transmission band body is continuously linearly reciprocally moved, the blades being driven by the transmission band body to continuously reciprocally move.   
     
     
         2 . A band-type fan structure comprising:
 a transmission band body, which is an elongated band body;   multiple blades side by side disposed on the transmission band body along the transmission band body in parallel to each other, each blade having a main body disposed on a surface of the transmission band body and a first end extending from the main body and protruding from the transmission band body, each two adjacent blades defining therebetween a flow way; and   a power member electrically connected to the transmission band body for making the transmission band body continuously linearly reciprocally move, whereby the blades are driven by the transmission band body to continuously reciprocally move.   
     
     
         3 . The band-type fan structure as claimed in  claim 2 , further comprising a case having at least one bottom board and two sidewalls disposed on two opposite sides of the bottom board, the bottom board and the sidewalls together defining a receiving space for receiving the transmission band body and the blades, the receiving space communicating with the flow ways between the blades. 
     
     
         4 . The band-type fan structure as claimed in  claim 3 , wherein the surface of the transmission band body has multiple connected sections, one face of the main body of the blade, which face is proximal to the transmission band body, is connected with the connected section. 
     
     
         5 . The band-type fan structure as claimed in  claim 4 , wherein the connected section is an insertion hole or a threaded hole and is an insertion pin or a screw, a connection section of the main body corresponding to the connected section being an insertion pin or a screw, the connected section being connected with the main body by means of insertion or screwing. 
     
     
         6 . The band-type fan structure as claimed in  claim 1 , wherein the blades are wing-shaped. 
     
     
         7 . The band-type fan structure as claimed in  claim 1 , wherein the blade further has a second end extending from the main body in a direction opposite to the first end and protruding from the transmission band body. 
     
     
         8 . The band-type fan structure as claimed in  claim 1 , wherein the first ends of the blades are made of flexible material. 
     
     
         9 . The band-type fan structure as claimed in  claim 2 , wherein the first ends of the blades are made of flexible material. 
     
     
         10 . The band-type fan structure as claimed in  claim 7 , wherein the second ends of the blades are made of flexible material or both the first and second ends of the blades are made of flexible material. 
     
     
         11 . The band-type fan structure as claimed in  claim 5 , wherein the transmission band body further defines a passageway in communication with the connected sections. 
     
     
         12 . The band-type fan structure as claimed in  claim 2 , wherein the power member has multiple transmission shafts and a power source, the transmission shafts being positioned on two sides of the passageway and connected with the power source.
