Abstract
The utility model relates to a composite blade which is suitable for a centrifugal ventilating impeller or a through-flow ventilating impeller in fields of ventilating, air-conditioning, vehicles, household appliances, industrial machinery, agricultural machinery, laser equipment, etc. The utility model is mainly characterized in that the composite blade is composed of one part of forward blades and the other part of backward blades connected with the forward blades in a smooth blend way. The utility model has the characteristic that the composite blade can effectively and simultaneously meet requirements for high efficiency, small size, low noise, etc.
Description
The utility model relates to a kind of blade, and it is applicable to the centrifugal ventilation impeller or the through-flow ventilation impeller in fields such as ventilation, air-conditioning, vehicle, household electric appliance, industrial machinery, farm machinery, Laser Equipment.
In background technique, blade is forward direction blade profile or back structure to blade profile, cause impeller or the efficient of utilizing its blade low, or physical dimension is big, or the noise height, can not meet the demands simultaneously well.For overcoming these defectives, the blade of centrifugal ventilation impeller or through-flow ventilation impeller is improved.
The purpose of this utility model is that a kind of compound blade will be provided, and it can satisfy the efficient height effectively simultaneously, the little and low requirement of noise of size.
The purpose of this utility model is achieved in that
It adopts the forward direction blade profile by a part, and another part adopts be connected with forward direction blade profile rounding off back to constitute to blade profile.
Described blade is the identical straight sheet of cross section, also can be wedged plate, also can be the distortion sheet.
The utility model is compared the good effect that is produced with background technique:
1, because it is compound blade, so it can satisfy the efficient height effectively simultaneously, the little and low requirement of noise of size.
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is a kind of structural drawing of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is an another kind of structural drawing of the present utility model.
Fig. 4 is the left view of Fig. 3.
Fig. 5 is the third structural drawing of the present utility model.
Fig. 6 is applied to the structural drawing of centrifugal ventilation impeller for the utility model.
Fig. 7 is the A-A sectional view of Fig. 6.
Fig. 8 is applied to the structural drawing of through-flow ventilation impeller for the utility model.
Fig. 9 is the B-B sectional view of Fig. 8.
Referring to accompanying drawing, centrifugal ventilation impeller is fixed on the chassis 3 that has the axle sleeve 2 that is connected with motor shaft by the compound blade 1 of multi-disc, is rotated spiral case being arranged or do not have in the state of spiral case by driven by motor, thereby drive gas motion, produce blast, wind speed plays draught effect.Through-flow ventilation impeller is fixed on the end cap first 7 that has the axle sleeve 2 that is connected with motor shaft by compound blade 1 one ends of multi-disc, the other end is fixed on the end cap second 5 that has the end axle 6 that matches with bearing, middle fixing by several dividing plates 4, rotate in spiral case by driven by motor, air-flow enters impeller from the side perpendicular to axis, pass the inside of impeller, discharge from the opposite side perpendicular to axis, impeller produces blast by the drive acting of motor, wind speed plays the effect of ventilation.
