Abstract
The utility model provides a novel fan, and relates to the technical field of ventilation equipment. The novel fan comprises a fan blade (1), a connecting device (2), a blind window (3), a wind collecting cylinder (4) and a flow guide cover (5), wherein the fan blade (1) is arranged in the collecting cylinder (4) by the connecting device (2), a small diameter edge of the wind collecting cylinder (4) is provided with the flow guide cover (5), and the outer end of the flow guide cover (5) is provided with the blind window (3). The fan blade is made from the cast aluminum material, so that the novel fan is firm, durable, hard to deform, long in service life, small in resistance, large in air quantity, reasonable to design the blind window of the fan, small in force during turning and off, hard to damage a counter weight hammer, small in electricity consumption, and electric energy-saving.
Description
Technical field:
The utility model relates to the ventilation equipment technical field, is specifically related to a kind of novel blower fan.
Background technique:
In the livestock breeding process, plant aeration-cooling extremely important keeps ventilation in the plant can effectively promote the benefit of plant, six flabellums of the general employing of existing plant blower fan, the resistance that is subjected in rotation process is big, the air quantity that produces is little, and flabellum adopts stainless steel material to make mostly, and resiliently deformable takes place long-time use the easily, life-span is short, and the venetian blind of blower fan has very big rotary inertia in opening process, damages counter weight easily, and power consumption is many.
The model utility content:
The purpose of this utility model provides a kind of novel blower fan, its flabellum adopts casting aluminium material to make, and is durable, not yielding, long service life, resistance is little, and air quantity is big, and the blower fan louvered design is reasonable, the power that produces in the switching process is little, not fragile counter weight, and little power consumption, saving power.
In order to solve the existing problem of background technique, the utility model is taked following technological scheme: it comprises flabellum 1, connection set 2, venetian blind 3, holds together air duct 4 and air guide sleeve 5, flabellum 1 is arranged in the air duct 4 by connection set 2, the path limit of holding together air duct 4 is provided with air guide sleeve 5, and the outer end of air guide sleeve 5 is provided with venetian blind 3.
Described air guide sleeve 5 inside are provided with louver frame 6, pivoted arm 7, blinds folder 8 and counter weight 9, and louver frame 6 is provided with blinds folder 8, are fixed with pivoted arm 7 on the blinds folder 8, and counter weight 9 is fixed on the louver frame 7 by screw.
Described flabellum 1 adopts casting aluminium material to make, and makes flabellum 1 not yielding.
Described flabellum 1 section is streamlined, meets principle of dynamics.
Suction by blower fan when the utility model uses makes venetian blind open certain angle, the angle difference, and counter weight moves thereupon, and corresponding skew, not fragile counter weight take place in its center of gravity.
The utlity model has following beneficial effect: its flabellum adopts casting aluminium material to make, and is durable, not yielding, long service life, resistance is little, and air quantity is big, and the blower fan louvered design is reasonable, and the power that produces in the switching process is little, not fragile counter weight, and little power consumption, saving power.
