The utility model provides a kind of centrifugal blower of range hood, thereby realize quick, the easy installation of air inlet ring, improves efficiency of assembling.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of centrifugal blower of range hood, comprise spiral case, be installed in the impeller in the set hollow cavity of spiral case, the motor of the air inlet ring that is arranged on impeller end face and drives impeller motion, wherein spiral case comprises spiral case top board, it is characterized in that being provided with on spiral case top board fixedly buckle of some air inlet rings, the corresponding fixedly buckle in air inlet ring edge is provided with the draw-in groove of equal number, and the fixed card that air inlet ring is fixed on spiral case top board by draw-in groove is buckled.
Preferably, the quantity of buckle and draw-in groove is at least 2.In the utility model, for guaranteeing the soundness of air inlet ring assembling, the quantity setting of buckle and draw-in groove is at least to 2.
Preferably, buckle comprises snap seats and the card that is cylinder shape, and the edge of draw-in groove is provided with the arc-shaped edges that matches with snap seats and card.In the utility model, Button Block plays circumferentially spacing and radially spacing effect to the arc-shaped edges of air inlet ring, and card plays the effect of compression to the arc-shaped edges of air inlet ring.
Preferably, the leading edge of card is provided with the flange of digging several angle.The leading edge of the utility model card is provided with the flange of digging several angle, more convenient when air inlet ring is installed.
Preferably, on described spiral case top board, be also provided with air inlet ring fixing screw hole, air inlet ring is fixed by screws on spiral case top board.
Compared with prior art, the beneficial effect of technical solutions of the utility model is: the air inlet ring of centrifugal blower of the present utility model adopts by the assembling mode being clasped, and buckle adopts cylinder deck and card structure mode, air inlet ring is carried out to circumference and radially bidirectionally limited, compression, assemble faster, convenient, reliable.
