Abstract
The utility model discloses a centrifugal blower which comprises a motor, a centrifugal wind wheel driven by the motor, and a volute covered on the centrifugal wind wheel, wherein the volute is provided with an air inlet and an air outlet, the centrifugal wind wheel is positioned between the air inlet and the air outlet; when the centrifugal blower works, the motor drives the centrifugal wind wheel to rotate to generate negative pressure suction so as to inhale air into the volute from the air inlet, and to supply air from the air outlet after the air is pressurized by flowing though the centrifugal wind wheel; and the centrifugal blower has strong applicability, good air supply effect and low noise, thus being widely applied to manufacturing of the centrifugal blowers.
Description
Technical field
The utility model relates to a kind of air-stream generating device, particularly a kind of centrifugal blower.
Background technique
Present centrifugal blower on the market, comprise housing, housing is provided with intake grill and exhaust outlet, in housing, be provided with impeller by driven by motor, noise was big when the propeller type centrofugal blower fan was worked, inapplicable to the demanding place of quiet degree, so develop the research schedule that the little centrifugal blower of a kind of noise has been put on people.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of noise little centrifugal blower.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of centrifugal blower, it comprises motor, by motor-driven centrifugal wind wheel be located at spiral case on the centrifugal wind wheel, and described spiral case is provided with intake grill and exhaust outlet, and described centrifugal wind wheel is between intake grill and exhaust outlet;
As improvement of the technical scheme, described centrifugal blower wind wheel comprises upper and lower ring washer, is provided with some unidirectional blades between the upper and lower ring washer, and the neutral position of described centrifugal blower wind wheel is provided with pedestal, and the mounting hole that motor is installed is set on the pedestal;
As further improvement in the technical proposal, described motor is fixedly connected on the spiral case by electric machine connecting support, described electric machine connecting support comprises that upper and lower support is formed by fixedly connecting, upper bracket is made up of chassis and the side arm that is distributed on the chassis, described side arm is provided with the attachment hole that is connected with spiral case, described lower support frame is made up of base and the link arm that is distributed on the base, fixedlys connected by fixing bolt between described side arm and the link arm.
The beneficial effects of the utility model are: rotated by the driven by motor centrifugal wind wheel during work of this product, produce negative-pressure sucking, air is sucked in the spiral case from intake grill, flow through and blow from exhaust outlet after the centrifugal wind wheel supercharging, this product applicability is strong, and blow effective, noise is little, thereby can be widely used in the making of centrifugal blower.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
