Description
【Technical field】
The present invention relates to a kind of radiator fans, particularly a kind of radiator fan for electrical motor of sewing machine.
【Background technology】
Electrical motor of sewing machine fan is a kind of for radiating, and the end face of the pedestal of general traditional electrical motor of sewing machine fan is all
It is plane, therefore, adjacent two panels flabellum and the air duct groove depth that pedestal end face is formed are uniform, when such electric motor fan operates
Exhaust air rate is inadequate, and the shortage of heat that motor generates when working be easy to cause electrical fault, there is existing wind to disperse
Fan needs to increase its air output, then needs to increase the length dimension of flabellum the diameter increase so that fan, therefore result in
The volume increase of entire fan.
【Invention content】
The invention is to solve the above problems, provide a kind of radiator fan for electrical motor of sewing machine, this radiator fan
Air draft is big, can achieve the effect that heat dissipation very well.
Technical solution is as follows used by the invention：
A kind of radiator fan for electrical motor of sewing machine, the radiator fan 1 include pedestal 11, are equipped on pedestal
Axle sleeve 13 positioned at middle part and several flabellums 12 around axle sleeve 13, the flabellum 12 are vertically arranged relative to pedestal 11,
Adjacent two panels flabellum 12 surrounds air duct slot 14 with 13 peripheral surface of axle sleeve and pedestal 11, and the air duct slot 14 is at axle sleeve
Depth is less than outer peripheral depth of the air duct slot close to pedestal.
14 bottom wall of air duct slot is equipped with step 141, the step 141 along radiator fan 1 from inside to outside
Radial direction declines, and 12 upper surface of flabellum is high outside interior bottom.
12 upper surface of flabellum is plane.
The upper surface of several flabellums of the circular axle sleeve 13 is mutually surrounded with the end face of axle sleeve 13 causes radiator fan 1
Middle part forms a recess.
14 bottom wall of air duct slot is along the inclined surface that the radial direction of radiator fan 1 from inside to outside is in interior high outer bottom
142,12 upper surface of flabellum is plane.
The inclined surface 142 is cambered surface.
The height of the flabellum 12 is gradually increased along the radial direction of radiator fan 1 from inside to outside.
The axle sleeve 13 is equipped with the location hole 131 being fixed on electric machine main shaft, and the location hole 131 is non-circular hole.
The number of sheets of the flabellum 12 is 8 to 12.
The radius that the length of the flabellum 12 along the radial direction of pedestal 11 is more than pedestal 11 causes 12 part of flabellum to dash forward
Go out outside the edge of pedestal 11.
It is the advantages of the invention compared with prior art：
1. radiator fan described in includes pedestal, axle sleeve and several flabellums around axle sleeve setting, the flabellum phase
Pedestal is vertically arranged, adjacent two panels flabellum surrounds air duct slot, the phase of the air duct slot with axle sleeve peripheral surface and pedestal
The depth of pedestal is increased along the radial direction of radiator fan from inside to outside.The air duct slot space of the invention from interior and
Outer increases, and radiator fan rotates exhaust air rate bigger, can reach good heat dissipation effect.
2. 14 bottom wall of air duct slot described in is equipped with step 141, the step 141 along radiator fan 1 from inside to outside
Radial direction decline, 12 upper surface of flabellum is the outer height in interior bottom.The bottom wall of pedestal is arranged to from inside to outside by the present invention
What is declined is step-like, can not only increase the air draft space of air duct slot, can also strengthen the pedestal intensity of radiator fan so that dissipating
The service life of Hot-air fan is extended；The flabellum upper surface is high outside interior bottom, can increase flabellum in this way along axle sleeve
The height of axis direction is so that the exhaust air rate increase of radiator fan；Relative to existing fan by increase fan diameter come
Increasing exhaust amount, it is of the invention then be to be conducive in this way come increasing exhaust amount save radiator fan peace by the height increase of flabellum
Space on sewing machine.

【Specific embodiment】
1 to 8 the invention is further detailed below in conjunction with the accompanying drawings：
With reference to Fig. 1 to 4, embodiment one：
A kind of radiator fan for electrical motor of sewing machine, the radiator fan 1 include pedestal 11, are equipped on pedestal
Axle sleeve 13 positioned at middle part and several flabellums 12 around axle sleeve 13, the flabellum 12 are vertically arranged relative to pedestal 11,
Adjacent two panels flabellum 12 surrounds air duct slot 14 with 13 peripheral surface of axle sleeve and pedestal 11, and the air duct slot 14 is at axle sleeve
Depth is less than outer peripheral depth of the air duct slot close to pedestal.Compared to the air duct slot of conventional fan, the invention
Air duct slot space increasing from inside to outside, radiator fan rotates exhaust air rate bigger, can reach good heat dissipation effect.
It is further preferred that 14 bottom wall of air duct slot is equipped with step 141, the step 141 is along radiation air
The radial direction of fan 1 from inside to outside declines, and 12 upper surface of flabellum is height outside interior bottom, meanwhile, the present invention can also be by institute
12 upper surface of flabellum stated is set as plane.The present invention bottom wall of pedestal is arranged to decline from inside to outside it is step-like, not only
The air draft space of air duct slot can be increased, the pedestal intensity of radiator fan can also be strengthened so that the service life of radiator fan obtains
To extend；The flabellum upper surface is outer high for interior bottom, flabellum can be increased in this way along the height of axle sleeve axis direction thus
So that the exhaust air rate increase of radiator fan；Relative to existing fan by increasing fan diameter come increasing exhaust amount, the present invention
It is then to be conducive in this way come increasing exhaust amount save the sky that radiator fan is mounted on sewing machine by the height increase of flabellum
Between.
Make it is further preferred that the upper surface of several flabellums of the circular axle sleeve 13 and the end face of axle sleeve 13 mutually surround
