Abstract
The utility model discloses a ventilator with convex rib blades. The ventilator comprises a fan shell (1), a motor (3), a blade fixing frame (4) and blades (2), wherein the motor (3) is fixed inside the fan shell (1); the blade fixing frame (4) is fixed on a rotating shaft of the motor (3); the blades (2) are fixed on the blade fixing frame (4); and convex ribs (21) are molded on the blades (2). Under the condition that rated air amount is achieved, the blades are manufactured to be thinner than the conventional blades, so that the material is saved, the production cost is reduced, and moreover, the strength of the blades is increased; and meanwhile the blades are attractive.
Description
Technical field:
The utility model relates to the ventilator technical field, more specifically to a kind of ventilator with convex tendon blade.
Background technique:
Propeller fan is in producing and living, to use the most a kind of ventilator; Because this ventilator is simple in structure; Its most important two parts is blade and motor, from consideration energy-conservation, aspect such as reduce production costs, present propeller fan manufacturing enterprise the improvement of blade as main research direction; The thickness that adopts the alternate material of lightweight to make blade and reduce blade all is to realize energy-conservation and the effective means that reduces production costs; But the adverse consequences that adopts above-mentioned mode to bring is exactly: the insufficient strength of blade, blade vibrates in high speed rotating, even the situation of deformable blade takes place.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology; And a kind of ventilator with convex tendon blade is provided, reaching under the situation of nominal air delivery original thinner of the ratio that its blade is done; Save material; Reduce production costs, but also increased the intensity of blade, make that simultaneously blade is more attractive in appearance.
The technological solution of the utility model is following:
A kind of ventilator with convex tendon blade comprises Blower Housing, motor, vanes fixed frame and blade, and motor is fixed in the Blower Housing, and the vanes fixed frame is fixed in the rotating shaft of motor, and vanes fixed forms convex tendon on the blade on the vanes fixed frame.
Said blade is a low arc shaped blade between four limit senior middle schools, and the extension direction of convex tendon is along the sense of rotation of motor, and said convex tendon is formed by one time punching molded.
Said vanes fixed frame is through in the rotating shaft that is bolted to motor.
Said blade pass is crossed rivet and is fixed on the vanes fixed frame.
The bottom of said Blower Housing is fixed with support.
The beneficial effect of the utility model is: form convex tendon on its blade; This convex tendon can improve the intensity of blade, is reaching under the situation of nominal air delivery, can be with original thinner of the ratio that blade is done; Save material; Reduce production costs, but also increased the intensity of blade, make that simultaneously blade is more attractive in appearance.

Embodiment:
Embodiment: see Fig. 1, shown in 2; A kind of ventilator with convex tendon blade; Comprise Blower Housing 1, motor 3, vanes fixed frame 4 and blade 2, motor 3 is fixed in the Blower Housing 1, and vanes fixed frame 4 is fixed in the rotating shaft of motor 3; Blade 2 is fixed on the vanes fixed frame 4, forms convex tendon 21 on the blade 2.
Said blade 2 is a low arc shaped blade between four limit senior middle schools, and the extension direction of convex tendon 21 is along the sense of rotation of motor 3, and said convex tendon 21 is formed by one time punching molded.
Said vanes fixed frame 4 is through in the rotating shaft that is bolted to motor 3.
Said blade 2 is fixed on the vanes fixed frame 4 through rivet.
The bottom of said Blower Housing 1 is fixed with support 5.
Working principle: form a convex tendon 21 on the blade 2 of the utility model; This convex tendon 21 can improve the intensity of blade, is reaching under the situation of nominal air delivery, can be with original thinner of the ratio that blade is done; Save material; Reduce production costs, but also increased the intensity of blade, make that simultaneously blade is more attractive in appearance.
