Embodiment
Below in conjunction with accompanying drawing, the better embodiment of impeller is described.
Please refer to Fig. 1 to Fig. 3, a kind of impeller 100, comprise middle reel 110, be fixed on the wheel disc 120 outside reel 110 and be fixed on multiple blades of wheel disc 120 upper surface.
Reel 110 is cylindrical, offers through hole 112 in the middle part of it, in order to be fixed on running shaft, to rotate under the drive of running shaft, and then makes multiple blades of wheel disc 120 upper surface 122 can putting in blast.
Wheel disc 120 is roughly plate-like, arranges around reel 110.Please refer to Fig. 3, the upper surface 122 of wheel disc 120 is arranged in cambered surface.Blade comprises linear leaf 132 and short blade 134 two kinds of blades.Linear leaf 132 and short blade 134 are straight line type blade, and itself is not bending, is respectively arranged with multiple, and all extends along the direction away from reel 110.Short blade 134 is forming difference near one end of reel 110 and linear leaf 132, is equivalent to a linear leaf to clip a part from the one end near reel 110.In reality, reel 110, wheel disc 120 and blade etc. all can integrally process, as utilized injection moulding process; Welding manner can also be adopted to be spliced.The edge of wheel disc 120 will lower than the bottom of reel 110, the reel 110 of such impeller 100 be mounted to motor shaft time, blade is not easy same motor casing and interferes.
Linear leaf 132 and short blade 134 are mingled with setting mutually.Need point out, herein be mutually mingled with to arrange should do the explanation of broad sense, can be arrange one or more linear leaf 132 continuously, and then arrange one or more short blade 134 continuously.Putting before this, multiple situation can had.Such as, in the present embodiment, be arranged alternately by the mode of a linear leaf 132 and a short blade 134.Can also be first arrange a linear leaf 132, then two short blades 134 are set continuously, and then a linear leaf 132 is set, the like.And for example, can also be that two linear leafs 132 are set continuously, then a short blade 134 is set, and then two linear leafs 132 are set continuously, the like.Linear leaf 132 and short blade 134 interval are arranged, and usually reach a kind of effect be evenly arranged.
In addition, in the present embodiment, linear leaf 132 and short blade 134 respectively arrange by Central Symmetry mode.For linear leaf 132, multiple linear leaf 132 circumferentially on the upper surface 122 of wheel disc 120, and forms the multipair linear leaf being symmetry center with reel 110.Multiple short blade 134 is arranged in a similar manner, repeats no more.
Above-mentioned impeller 100 has higher air-cooled ability, and axle consumption is little, and this advantage can be recorded by test.Air-cooled ability depends on the size of air quantity, and therefore testing air-cooled ability is test air force.Wind quantity test equipment is the anemoscope that those skilled in the art commonly use, and axle consumption testing apparatus is then ammeter.Test method is summarized as follows: other dissimilar impeller and above-mentioned impeller 100 are arranged on respectively in same motor, carries out test successively and record test data to 3 exhaust outlets of motor.Each exhaust outlet selects 8 measuring points, tests wind speed respectively, gets the mean value of multiple test data, more accurately objective with the wind speed making calculating air quantity used, then utilizes the area of wind speed and exhaust outlet to calculate air quantity; Utilize ammeter can obtain axle consumption (i.e. the energy of electrical consumption) of motor when installing different impeller.
In the present embodiment, use the impeller test wind speed of three types and calculate the axle consumption of motor, then comparing.The first impeller is the impeller 100 of the present embodiment; With impeller 100 for reference, impeller 2 is: sheave surface is plane, and blade is all linear leaf; With impeller 100 for reference, impeller 3 is: sheave surface is cambered surface, and blade is all linear leaf.
Test average result is as shown in the table:
| Air quantity (m 3/h） | Axle consumption (w) | |
| Impeller 100(sheave surface is cambered surface, long and short blade) | 0.023 | 0.92 |
| Impeller 2(sheave surface is plane, whole linear leaf) | 0.017 | 1.37 |
| Impeller 3(sheave surface is cambered surface, whole linear leaf) | 0.018 | 1.22 |
Can be known by above-mentioned test result, in the impeller testing the three types used, the air quantity of impeller 100 is larger, and axle consumption is low.Thus, compared with the impeller of other types, the mode that cambered surface is arranged and deviated splitter vane combines of the impeller 100 of the present embodiment, can improve cooling capacity, reduces the axle consumption of fan.
In addition, additionally provide a kind of fan, this fan adopts motor platform, please refer to Fig. 4, and incorporated by reference to Fig. 1 to Fig. 3, this fan comprises motor and above-mentioned impeller 100.Motor comprises motor casing 210, is contained in motor casing 210 and the motor shaft 220 that can rotate around own axes.Motor can be brushless or brush motor.
Motor casing 210 is stretched out in one end of motor shaft 220, and the reel 110 of impeller 100 is set in the end of motor shaft 220.The end that motor shaft 220 installs impeller 100 is also fixed with clutch shaft bearing 230, is resisted against on the reel 110 of impeller 100, in order to locate impeller 100.Motor casing 210 is also stretched out in the other end of motor shaft 220, and it is fixed with the second bearing 240.Like this, said fans can be installed in the housing of power tool, and motor shaft 220 can rotate around own axes, can drive working head work like this by another end of driving mechanism motor shaft 220.Power tool can be the power tool of the type such as electric drill class, angle mill class, sawing class, electric hammer class.
In the present embodiment, when impeller 100 is fixed on motor shaft 220, blade setting close to motor casing 210.When said fans is used in power tool, motor shaft 220 is gone back impeller 100 and is rotated while the work of driving working head, thus reaches the object of cooling motor.And chatted above, the cambered surface setting of impeller 100 and the plan of establishment of deviated splitter vane, can improve cooling effect, the axle consumption of fan is also lower.If blade back is arranged from motor casing 210, then said fans can be used for cooling other operation elements, makes fan also can be applied in other workplaces, can reach good cooling effect equally, and the axle of fan consumption is also lower.
The above embodiment only have expressed several mode of execution of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
