Embodiment

So, for making the public can fully understand the present invention, as follows by Figure of description explanation:

As shown in Figure 1, it is circulation fan structure of the present invention, and the present invention at least comprises:

Dynamical element 1, for DC Brushless Motor, d.c. motor or alternating current motor are all without can not, but the present invention is usingd DC Brushless Motor as the power resources that drive axial flow flabellum, to meet the usefulness of power saving environmental protection, aforementioned dynamical element 1 is fixedly arranged in the engagement groove 310 of rear safety net 31 of diversion member 3, and establishes element 11 fixing (as Fig. 2 and 3) with bolt.

Axle 10 in aforementioned dynamical element 1 is provided with axial flow flabellum 2(as Fig. 2 and 3), aforementioned axle 10 belongs to known technology with the combination of axial flow flabellum 2, therefore, repeats no more.Aforementioned axial flow flabellum 2 is established a plurality of blades 20, the radian R of the outermost periphery 200 of aforementioned blade 20 equal or close to the radian R(of the interior training wall 32 of diversion member 3 as Fig. 3-5), and allow the outermost periphery 200 of aforementioned blade 20 be able to form minimum spacing d with the interior training wall 32 of diversion member 3, its objective is that adverse current occurs in diversion member to be reduced air-flow, cause occurring sinuous flow phenomenon, affect air-flow output stability, the distance that be more increased discharge quantity of fan and air-flow enter indoor or environment space.

Diversion member 3, is provided with forward and backward

safety net

30,31, and to protect user's safety, the rear safety net 31 of aforementioned diversion member 3 is established engagement groove 310, and aforementioned dynamical element 1 is arranged at wherein, and is fixed.Aforementioned forward and backward

safety net

30,31 with bolt, establishes element 301,311 respectively and diversion member 3 sets firmly.In aforementioned diversion member 3, establish interior training wall 32(as Fig. 7 A, 7B and 7C), aforementioned interior training wall 32 is also established larger opening in air flow inlet 33, and flow outlet 34 is established little opening, namely the internal diameter of air flow inlet 33 is greater than the internal diameter of flow outlet 34 and forms the state dwindling, allow a large amount of air-flows enter fast in diversion member, be able to be concentrated and air-guiding direction, use minimizing resistance, promote the flow of air-flow.

Moreover, in the diversion member 3 of earlier figures 7B, do not establish interior guide vane 4, or as shown in Figure 7 A, in aforementioned diversion member 3 is interior, be provided with interior guide vane 4 simultaneously, aforementioned interior guide vane 4 is comprised of a plurality of blades 40, be the slightly inner side that is arranged at the flow outlet 34 of aforementioned diversion member 3, and be formed in one and make (as Fig. 6,7A and 8) with aforementioned diversion member 3; Or as shown in Fig. 7 C and 9, described diversion member 3 is provided with guide vane 4a, and this guide vane 4a, described guide vane 4a includes a plurality of blades 40, and this guide vane 4a is arranged with diversion member for 3 minutes, then with bolt, establishes element described guide vane 4a and diversion member 3 bolts are established and are combined into one.The object that aforementioned guide vane is set is to be able to the air-flow of interior training wall 32 to be guided and produce cyclone strength when flow outlet 34 is exported, and the output distance that is extended air-flow, promotes the effect that indoor air flow circulates.
