Abstract
The invention relates to a fan blade. The fan blade comprises a hub, a lantern ring which is arranged and combined on the hub in a sleeved mode and blade bodies which integrally and outwards extend from the outer circumferential face of the lantern ring. One end of the hub is a positioning end. The lantern ring and the hub are manufactured in an isolated mode. The lantern ring is provided with a first installation end and a second installation end which is opposite to the first installation end. When the first installation end of the lantern ring is in contact with the positioning end of the hub, the fan bodies are arranged in an inclined mode in the clockwise direction by being opposite to the positioning end of the hub so as to meet the requirements for using the fan bodies to rotate in the clockwise direction and in the anti-clockwise direction.
Description
Technical field
The present invention relates to a kind of flabellum, refer to especially a kind of flabellum of radiation fan.
Background technique
Current, along with developing rapidly of computer industry, the heat that the heat-generating electronic elements such as micro-chip processor produce is more and more many.For the heat that these are unnecessary effectively distributes, existing method is the radiator that is sticked on the surface of heat-generating electronic elements, then one fan is set on this radiator, the cooling blast that utilizes this fan to produce carries out forced heat radiation to this radiator, thereby the heat that heat-generating electronic elements is produced leaves.
Some blades that the flabellum of existing fan generally includes a wheel hub and extended by the outside one of the outer periphery of wheel hub.Described blade is obliquely installed usually clockwise or counterclockwise, with wind sweeping area and the minimizing noise texts that improves blade.Yet, because wheel hub and the blade of existing flabellum are one-body molded, can only meet the demand of blade along the single direction rotation, when when adapting to different demands and change the blade lean direction, also need other die sinking making, cost is higher.
Summary of the invention
In view of this, be necessary to provide a kind of adapt to along just, the flabellum of contrary both direction rotation.
A kind of flabellum comprises that a wheel hub, sheathedly is incorporated into the blade that the collar on wheel hub and some outside one of outer circumferential face by the collar are extended, one end of this wheel hub is positioning end, the described collar separates manufacture with wheel hub, the described collar has the first relative mounting end and the second mounting end, when the first mounting end of the described collar contacts with the positioning end of wheel hub, the positioning end of the relative wheel hub of described blade is obliquely installed along clockwise direction; When the second mounting end of the described collar contacts with the positioning end of wheel hub, the positioning end of the relative wheel hub of described blade is obliquely installed in the counterclockwise direction.
A kind of flabellum comprises that a wheel hub reaches an impeller of detachably being located at this wheel hub periphery, and this impeller comprises that the collar detachably be sheathed on wheel hub reaches the some blades by the outward-dipping extension of the collar.
Compared with prior art, the direction that above-mentioned flabellum can be sheathed on by the collar of adjusting impeller the wheel hub periphery changes the true dip direction of blade with respect to wheel hub, with meet flabellum along just, the user demand of contrary both direction rotation, improve versatility.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
As shown in Figure 1, this flabellum 10 comprises that a wheel hub 100 reaches an impeller 200 of detachably being located at these wheel hub 100 peripheries.
Please consult Fig. 2, this wheel hub 100 comprises a roof 101 and the annular wall 103 to downward-extension by the periphery of this roof 101 simultaneously.On this roof 101, a rotating shaft (not shown) can be installed.The bottom of described annular wall 103 is a positioning end 104, and the outer circumferential face of this positioning end 104 stretches out and forms a flange 105.This roof 101 is that circular flat is tabular.Described annular wall 103 is extended and is formed downward vertically by the outer periphery of roof 101.The internal surface of this annular wall 103 can be provided with a magnetic element (not shown), with the stator with a motor, coordinates and drives flabellum 10 to rotate.Described flange 105 is by the outwards vertical extension of outer circumferential face of annular wall 103.
Described impeller 200 comprises that a collar 201 reaches by the outward extending some blades 203 of the outer periphery of this collar 201.Be provided with the metallic support sheet (not shown) of ring-type in the described collar 201, to increase the intensity of the collar 201.The described collar 201 separates manufacture with wheel hub 100, and its bottom is the first mounting end 206, and top is the second mounting end 204.The positioning end 104 of described blade 203 relative wheel hubs 100 is obliquely installed in the counterclockwise direction.Please consult Fig. 3 simultaneously, during assembling, the collar 201 of described impeller 200 can directly be set on the annular wall 103 of wheel hub 100, and its first mounting end 206 is resisted against on flange 105, again by mode combinations such as glue, now, the positioning end 104 of the blade 203 relative wheel hubs 100 of described impeller 200 is obliquely installed in the counterclockwise direction; As shown in Figure 4, the collar 201 of described impeller 200 sheathed being combined on wheel hub 100 again after also can being inverted, even the second mounting end 204 of the collar 201 is resisted against on flange 105, blade 203 is obliquely installed along clockwise direction, thereby meet flabellum 10 along just, the user demand of contrary both direction rotation, improve versatility.With respect to existing integrally formed flabellum, without die sinking manufacture in addition again, cost-saving.
During concrete enforcement, detachable marriage relation between described wheel hub 100 and impeller 200 is not limited to the situation of above-described embodiment, also can be by as one, projection being set between the two, another arranges the buckle mode combinations such as draw-in groove, thereby impeller 200 can be disassembled easily from wheel hub 100, make flabellum 10 in use can adjust easily the sense of rotation of blade 203 according to different demands, further strengthen its versatility.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change and distortion all should belong to the protection domain of the claims in the present invention.
