Description
Technical field
The utility model relates to a kind of flabellum blade profile of avoiding injuring, but and the degree of balance of rapid adjustment fan and flabellum, to keep the electric fan equilibrium structure of balance of fan running.
Background technique
Electronics and IT products (for example: popularize day by day and use more extensive by use computer etc.) at present, because it is rapid that demand drives the electronics and information industry technical development, impel electronic information towards carrying out the trend development that arithmetic speed promotes, access capability increases, thereby causing the spare part in present electronics and IT products to have high temperature to supervene often at working at high speed, is in its position radiator or radiation fan to be set and the spare part in the general electronics and IT products is taked in order to the mode that solves heat radiation.
And the effect of fan is that its when running drives air-flow and moves, can produce thermoconvection thus and reach the purpose that heater is dispelled the heat, because mainly being the wheel hub at fan, general fan structure forms some flabellums outwardly, air-guiding moves when making rotation, if the fan center of gravity has skew, the phenomenon of when then it rotates generation being rocked or vibrating.
Above-mentioned rock or oscillation phenomenon not only makes fan produce noise, and can cause the axle center of fan to accelerate fatigue and shorten working life of fan more will be reduced the total quality of this fan product mix of application, and also can cause phenomenons such as heat dissipation is not good.Be illustrated in figure 1 as electric fan equilibrium structure of the prior art, this structure mainly is that 11 extension axle 12 inner edge one ejection formations form an internal projecting ring 13 in the axle center, form some fins 14 at internal projecting ring 13 and 12 on extension axle, and be formed with counterweight slotted eye 15 between 14 of each fins, this counterweight slotted eye 15 can supply the balancing weight 16 of plant different length, weight, and make balancing weight 16 and 15 of counterweight slotted eyes be the drive fit state, for proofreading and correct the fan power balance.
Yet, when the electric fan equilibrium structure that prior art provides is applied in actual production, need at described balancing weight 16 casting mould separately, and described mould must be quite accurate, must make this balancing weight 16 can when planting described counterweight slotted eye 15, keep the drive fit state really, otherwise when fan rotates, may cause described balancing weight 16 to come off and lose the effect of correction balance of fan.
The model utility content
Main purpose of the present utility model is, a kind of electric fan equilibrium structure is provided, and it can effectively avoid the flabellum blade profile destroyed by operation, and can reach the running of maintenance balance of fan simultaneously fast.
Another purpose of the present utility model is, provides a kind of and can be pasted with divider on equilibrium region, influences the aerodynamic characteristic of electric fan with the pothole of avoiding being formed after the balanced operation.For reaching above-mentioned purpose, the utility model provides a kind of electric fan equilibrium structure, mainly comprise: a wheel hub and a plurality of flabellum, described wheel hub is a hollow casing, and wheel hub outside side extends and is arranged with described flabellum, and this wheel hub defines an outer wall between the end face flabellum adjacent with side, then defines the equilibrium region at least one place on the described outer wall, the defining of this equilibrium region can make the weight of fan described flabellum of balance when rotating, and described fan can be rotated on balance and stability ground.
The beneficial effect that the utility model reaches: this structure can avoid fan to cause the problem of vibration because of imbalance when rotating, and owing to be pasted with divider on this equilibrium region, can prevent that formed pothole after the balanced operation from influencing the aerodynamic characteristic of electric fan.
