Abstract
The utility model discloses a small-sized blower fan of a motor with cup rotor, which includes a stator component 1 composed of an iron core and a major-minor windings, and a rotor 2 composed of an iron core and a squirrel-cage guide strip, as well as a holder 3 and a blade 4, and the blade 4 principally includes a blade 41, a hollow circular ring 42 and a splice bar 43. The blade 41 has multiple pieces which are arranged and fixedly connected to the hollow ring 42 with same radianMultiple splice bars 43 are installed in the middle of the hollow circular ring 42, and inner ends of multiple splice bars 43 intersect at the circle center of the hollow circular ring 42, and intersecting point of inner ends of the multiple splice bars 43 is equipped with a blade mounting hole 44; the utility model has the advantages that: when the blade blows the wind forward, the wind which meets the core element and returns can cross blade through a hollow circular ring, thereby returned air-flow may reduce, the air mixed flow state is improved, noise is reduced, simultaneously the heat produced by the blower fan itself emits faster.
Description
Technical field:
The utility model relates to electric fan technology neck city, specifically is a kind of small-sized fan of motor with cup rotor.
Background technique:
The motor with cup rotor structural stability, reliable and do not have an electromagnetic interference, be widely used in the light start occasion, and the small-sized fan of being made by motor with cup rotor extensively is installed in household electric appliance especially, the motion device, Medical Instruments, the inside of electronic equipments such as various machinery, to reduce the heat that these electronic equipments are in operation and produce, safeguard the proper functioning of these electronic equipments.Existing motor with cup rotor small-sized fan, the rotor and retainer and the fan blade that comprise the stator module formed by iron core and major-minor winding, form by iron core and mouse cage sliver, the blade structure of existing motor with cup rotor small-sized fan, majority is made up of the contiguous block in the middle of air blade, each fan blade, the central authorities of contiguous block are provided with attachment hole, and the monoblock fan blade is fixed on the fan shaft front end by attachment hole.There is following deficiency in this blade structure, because this small-sized fan is the inside that is contained in electronic equipments, fan blade is blown into before with wind direction on the core components and parts in the electronic equipments, the heat that produces when turning round with the core components and parts that leave, but, the little electronic equipments inside in Shan, considerable distinguished and admirable being lived by shelves arranged when wind is to components and parts and turn back to the fan blade direction, again owing to be a monoblock contiguous block in the middle of the fan blade, the wind that returns can be blocked by the contiguous block in the middle of the fan blade again and return to back, in the little space, Shan between leaf place and components and parts, air stream is in a kind of mixed flow state, add the very fast rotation of fan blade, the very fast confusion of the air stream of this confusion flows, and just will inevitably produce bigger air mixed flow noise.Moreover this structure of fan blade makes to can not get radiating effect as soon as possible by the heat that the fast turn-around of motor with cup rotor blower fan own produces.
The model utility content:
The technical problems to be solved in the utility model is at the deficiency that above-mentioned prior art exists, to provide a kind of and can reduce the noise that blower fan itself produces, the motor with cup rotor small-sized fan that the heat that blower fan itself is produced can leave as early as possible.
Technical solution of the present utility model is:
The small-sized fan of motor with cup rotor, comprise the stator module of forming by iron core and major-minor winding, the rotor of forming by iron core and mouse cage sliver, and retainer and fan blade, it is characterized in that, described fan blade is mainly by air blade, hollow ring, connecting tendon is formed, described air blade is a multi-disc, be fixed on the described cavity ring Deng the radian arrangement, described connecting tendon is many, many connecting tendons are installed in the centre of described hollow ring, the inner of described many connecting tendons intersects at the center of circle of described hollow ring, and the inner intersection of described many connecting tendons is provided with the fan blade mounting hole.
Described many connecting tendons that are connected in the hollow ring are arranged for waiting radian.
The back of described air blade also is provided with a stiffening rib, and described stiffening rib is fixed on the described hollow ring with air blade.
After adopting above structure, compared with prior art, the utlity model has following advantage: owing to be arranged to the open circles ring-type in the centre of fan blade, when fan blade blows wind forward, run into the wind that returns behind the core components and parts and can pass fan blade by hollow ring, like this, the air mass flow of repeatedly backflowing back and forth between fan blade and core components and parts will reduce, air mixed flow state improves, its noise is also corresponding to be reduced, simultaneously, the hollow ring that wind can pass on the fan blade blows on the blower fan of fan blade back, thereby the heat that blower fan running itself is produced is also driven away faster.This structure not only make the core components and parts in the apparatus can get heat radiation faster, and blower fan itself has also obtained better radiating effect.
