Description
Technical field
The utility model is related to motor cooling fan technical field more particularly to a kind of motor cooling fans.
Background technology
Motor with cup rotor is widely used in the products such as air-heater, oven, exhaust fan, air-conditioning, refrigerator.Work as motor application
In the equipment such as air-heater, oven, it may be installed at heat source.Motor can be radiated by outside heat at this time, and have because
The heat of its own work and generation.When motor is heated, when temperature is increased to a certain extent, the working performance of motor can be by shadow
It rings, causes electrical machinery life to be shortened, in some instances it may even be possible to motor can be caused directly to shut down.
Therefore such motor would generally assemble a cooling fan, for drying to motor, while stop and disperseing in right amount
From in the heat of front complete machine, the Wen Sheng of motor is made to be unlikely to excessively high.But the present cooling flabellum used in the industry is yielding, makes
Cost is higher.The cooling fan structure that the use of the new type is proposed, purpose are just to solve problem above, are a kind of making molding letters
Single, the high motor of but intensity at low cost cools down flabellum.
Invention content
To solve above-mentioned problem of the prior art, the utility model provides a kind of motor cooling fan, simple in structure, technique letter
It is single, low manufacture cost, intensity height.
In order to reach object above, the utility model takes following technical scheme：A kind of motor cooling fan, main includes fan
Leaf and flabellum clamp spring, the rounded sheet of flabellum, centrally disposed mounting hole are evenly distributed with " L " connected in star on covering of the fan around mounting hole,
Uniformly distributed inclined rectangular open slot on flabellum circumference；The flabellum clamp spring is in arc surface, and center is equipped with mounting hole, mounting hole
Surrounding is evenly distributed with open slot；The flabellum is located at the right side of motor upper bracket, and the rotor of rotor is fixed on by flabellum clamp spring
On axis, upper bracket is between flabellum and motor stator.
Furtherly, described " L " connected in star and open slot are arranged in a crossed manner.
Furtherly, it is set on the armature spindle there are one card slot, flabellum clamp spring is mounted in card slot.
In use, after electrical power, rotor drives armature spindle rotation, and then flabellum is rotated together with armature spindle, directly
It connects to motor radiating, while can stop and disperse the heat generated from front oven in right amount, prevent motor temperature excessively high, it can
It realizes the cooling to motor and heat-blocking action, protects motor.
Compared with prior art, the utility model has the beneficial effects that：
1) blade structure is simple, mold one-pass molding, low production cost；
2) intensity of flabellum is increased, general structure flabellum is yielding, this structure adds the design of " L " connected in star, can be effective
Prevent blade；
3) good heat-insulation effect, flabellum farthest remain blade planform area, and notch is few, and heat insulation is more preferably.
Description of the drawings
It, below will be to implementing in order to illustrate more clearly of the utility model embodiment or technical solution in the prior art
Example or attached drawing needed to be used in the description of the prior art are briefly described, it should be apparent that, the accompanying drawings in the following description
It is some embodiments of the utility model, to those skilled in the art, under the premise of not staying alone creative work, may be used also
With obtain other attached drawings according to these attached drawings.
Fig. 1 is the mounting structure schematic diagram of the utility model；
Fig. 2 is the blade structure schematic diagram of the utility model；
Fig. 3 is the flabellum clip spring structure schematic diagram of the utility model；
Wherein, flabellum 1, flabellum clamp spring 2, mounting hole 3, " L " connected in star 4, open slot 5, mounting hole 6, open slot 7, upper branch
Frame 8, armature spindle 10, motor stator 11.
Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained without creative efforts belong to
The range of the utility model protection.
Embodiment 1：
As shown in the figure：A kind of motor cooling fan, mainly include flabellum 1 and flabellum clamp spring 2,1 rounded sheet of the flabellum,
Its centrally disposed mounting hole 3 is evenly distributed with " L " connected in star 4 on covering of the fan around mounting hole 1, uniformly distributed inclined rectangular on flabellum circumference
Open slot 5；The flabellum clamp spring 2 is in arc surface, and center is equipped with mounting hole 6, open slot 7 is evenly distributed with around mounting hole 6；The flabellum
1 is located at the right side of motor upper bracket 8, is fixed on the armature spindle 10 of rotor by flabellum clamp spring 2, and upper bracket 8 is located at fan
Between leaf 1 and motor stator 11.
" L " connected in star 4 is arranged in a crossed manner with open slot 5.
It is set on the armature spindle 10 there are one card slot, flabellum clamp spring 2 is mounted in card slot.
In use, after electrical power, rotor drives armature spindle 10 to rotate, and then flabellum 1 turns together with armature spindle 10
It is dynamic, directly to motor radiating, while it can stop and disperse the heat generated from front oven in right amount, prevent motor temperature mistake
Height protects motor, it can be achieved that the cooling to motor and heat-blocking action.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It still can be with technical scheme described in the above embodiments is modified, or is carried out to which part technical characteristic etc.
With replacement；And these modifications or replacements, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
