One diffusingsurface 127F, direction is guided in it to guide air-flow.In the present embodiment, the flat fan of open single-line type, application
The volume of fan nozzle is reduced in single straight line air-out, increases the portability and convenience of fan.
It is that the different embodiments for being directed to various internal fans in the utility model illustrate below.
Referring to Fig. 10, it is a preferred embodiment schematic diagram of the utility model internal fan, as shown in the figure：
It is a jet turbine Leaf Conductance fan 113A that the present embodiment, which discloses the internal fan, to suction airflow and spray
Go out air-flow, jet turbine Leaf Conductance fan 113A has：One turbine airflow exports 114A；One turbine airflow entrance 115A；
One turbo blade 116A；An and turbine motor 117A.Wherein turbo blade 116A is in vortex shape, air-flow to be directed to
Center and towards side turbine airflow outlet 114A send out.
Figure 11 is referred to, is another preferred embodiment schematic diagram of the utility model internal fan, as shown in the figure：
It is a blower fan 113B that the present embodiment, which discloses the internal fan, to suction airflow and sprays air-flow, the air blast
Fan has：One blower fan air stream outlet 114B；One blower fan air flow inlet 115B；One air blast fan leaf 116B；An and air blast
Fan motor 117B.Wherein air blast fan leaf 116B has flexure plane, air-flow is directed into center and towards the air blast of side
Air stream outlet 114B is fanned to send out.
Figure 12 is referred to, is a more preferred embodiment schematic diagram for the utility model internal fan, as shown in the figure：
It is a plane fan 113C that the present embodiment, which discloses the internal fan, to suction airflow and sprays air-flow, this is flat
Face fan 113C has：One plane fan air stream outlet 114C；One plane fan air flow inlet 115C；One plane fan blade
116C；An and plane fan motor 117C.The wherein plane fan 113C is to by a front side (plane fan air flow inlet
After air-flow 115C) imports, the rear side (a plane fan air stream outlet 114C) towards plane fan 113C is sent out, and is thus guided
Air-flow.
The application, which provides a kind of general fan of fan solution, to be had blade interference light and is not easy cleaning problems；Solve without Condar
The known fan without blades of effect (Coanda effect), the bad problem of air-out effect；Fan without blades are without diffusion known to solution
Face can not guide air-out effect problem；Solution simply combines nozzle overall volume problems of too.
Construction, feature and action effect of the present utility model is described in detail according to the embodiment shown in schema above, with
The upper only preferred embodiment of the present utility model, but the present invention is not to limit practical range shown in drawing, it is every according to this
The change that the conception of invention is made, or the equivalent embodiment of equivalent variations is revised as, still covered without departing from specification and diagram
Spirit when, all should be in the scope of protection of the utility model.
