Description
Technical field
The utility model relates to blower fan, especially relates to a kind of efficient small centrifugal blower of compact structure.
Background technique
Centrifugal blower is the mechanical energy relying on input, and improve gas pressure and to supply gas side by side the machinery of body, it is a kind of driven fluid machinery.Centrifugal blower is widely used in daily life and industrial processes, also the use of centrifugal blower is had in some household electric appliance, centrifugal fan is generally made up of casing, the impeller be arranged in casing, bearing transmission mechanism and the motor etc. arranged outside casing, the centrifugal blower volume of this structure is comparatively large, and household electric appliance in the design requirement reduce the volume of product while will ensureing to export.
Summary of the invention
For overcoming existing shortcoming, the utility model object is the efficient small centrifugal blower providing a kind of compact structure.
The utility model is realized by following technical measures, a kind of efficient small centrifugal blower, comprise drain pan, described drain pan is provided with exhaust outlet, described drain pan is covered with a cover, described cover is provided with intake grill, in described drain pan, motor is installed, the driving shaft of described motor is fixed with blower fan; Described blower fan comprises the inner casing of cone barrel type, described inner casing lower limb stretches out and forms retainer ring, described lower retainer ring upwards forms impeller, closes and be provided with a motor shaft fixed hole above the inner casing of cone barrel type, and the height of described impeller is higher than the height of the inner casing of cone barrel type.
As a kind of optimal way, described impeller blade top is connected by retainer ring on.
As a kind of optimal way, described impeller blade with the wind flow path direction forms arc.
Motor is arranged in the inner casing of cone barrel type by the utility model, and when motor runs, blower fan is rotated and sucked from cover by the air in the external world, discharges after impeller supercharging from exhaust outlet.The utility model greatly can save installing space, thus can process smaller and more exquisite product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the utility model embodiment blower fan structural representation seen from above;
Fig. 3 is the structural representation that the utility model embodiment sees from below;
Fig. 4 is the sectional view of the utility model embodiment blower fan.
Embodiment
Contrast accompanying drawing below in conjunction with embodiment the utility model is described in further detail.
A kind of efficient small centrifugal blower, referring to figs. 1 to Fig. 4, comprise drain pan 400, described drain pan 400 is provided with exhaust outlet 401, described drain pan 400 is covered with a cover 100, described cover 100 is provided with intake grill 101, in described drain pan 400, motor 300 is installed, the driving shaft of described motor 300 is fixed with blower fan 200; Described blower fan 200 comprises the inner casing 204 of cone barrel type, described inner casing 204 lower limb stretches out and forms retainer ring 205, described lower retainer ring 205 upwards forms impeller 202, close above the inner casing 204 of cone barrel type and be provided with a motor shaft fixed hole 201, the height of described impeller 202 is higher than the height of the inner casing 204 of cone barrel type.
Motor 300 is arranged in the inner casing 204 of cone barrel type by this centrifugal blower, when motor runs, blower fan 200 is rotated and is sucked from cover 100 by the air in the external world, discharge from exhaust outlet 401 after impeller 202 supercharging, this centrifugal blower greatly can save installing space, thus can process smaller and more exquisite product.
The efficient small centrifugal blower of the present embodiment, please refer to Fig. 2 and Fig. 3, and the basis of previous technique scheme can also be specifically, and impeller 202 blade tip is connected by retainer ring 203 on.
The efficient small centrifugal blower of the present embodiment, please refer to Fig. 2 and Fig. 3, and the basis of previous technique scheme can also be specifically, and impeller 202 blade with the wind flow path direction forms arc.
More than that the utility model efficient small centrifugal blower is set forth; the utility model is understood for helping; but mode of execution of the present utility model is not restricted to the described embodiments; any do not deviate from the utility model principle under do change, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
