Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
With reference to figure 1, of the present utility model without blade fan, comprise the compresses lower section 1002 of built-in fans circuit control section, the top section 1001 of built-in fans power plant and the ring nozzle 1000 that is used for the emission air-flow.
With reference to figure 3, ring nozzle 1000 of the present utility model is comprised of the inner passage 46 and the mouth that are continuous ring or pipeline.In this embodiment, described inner passage 46 comprises bottom 43 and sidewall 45, and described sidewall 45 bendings are also stretched to the below of bottom 43, leave gap or interval between described bottom 43 and the sidewall 45, form gas port 44.Described inner passage 46 can be one-body molded, and preferably peg graft in as shown in Figure 2 inner ring and inclined-plane, outer ring, also can be that pillar forms inserting.Described bottom 43 is a plane.Air-flow is through inner passage 46 like this, and 44 emit from the air outlet, directly runs at a long guide face, thereby drives on every side air-flow and back air-flow.Can allow air-flow more concentrated, and more simple on mould-forming.
The shape of the ring nozzle of the utility model fan can be circle, track type, polygonal etc., does not do concrete restriction at this.
As shown in Figure 2, the top section 1001 of fan of the present utility model is installed on the compresses lower section 1002, it is preferably formed by plastic materials, and preferably has roughly the same outer dia, so that the outer surface of top section 1001 and compresses lower section 1002 is substantially flush.The lower surface of top section and the upper surface of compresses lower section no longer specify at this for can be provided interconnected structure.Described compresses lower section 1002 comprises user interface and control circuit.
Top section 1001 comprises barrel-shaped shell 4, the sidewall of described shell 4 is provided with suction port 11, described suction port 11 can be for grid-like or netted, and shell 4 has held impeller 9, enters in the top section 1001 thereby pass suction port 14 for the suction main air flow.Impeller 9 is connected on the running shaft from from motor 1 to downward-extension.Described motor 1 can be DC Brushless Motor.It is contained in the motor casing in 7, and motor casing 7 is fixed in the centre circle 6, and described impeller namely, has formed the passage 13 that air-flow passes through between motor casing 7 and the centre circle 6 between motor casing 7 and centre circle 6.Centre circle 6 is being roughly frustoconical in shape, comprises the air intlet 12 that opens downwards, is used for receiving main air flow.The top of described centre circle 6 is provided with a lid 5, and lid 5 is provided with an air outlet slit 14.Being fixedly mounted with of centre circle 6 and shell 4 for example can be passed through a bellows type supporting member, can be to support such as natural rubber, is solidly installed by groove etc., no longer specifies at this.
