Description
Technical field
The utility model relates to mechanical engineering field, especially relates to the dustproof defeated blower fan of a kind of Wind Volume.
Background technique
Existing blower fan comprises housing, is provided with motor and fan in housing, and motor comprises motor body and rotating shaft, and fan is sheathed in rotating shaft, and in the process of defeated wind, the edge of wind blast wind fan leaf, causes its defeated wind efficiency low, and wind direction is mixed and disorderly, easily produces noise; And in the time that blower fan is used for air draft, the impurity such as the dust in wind easily enter in motor from the finedraw between motor body and rotating shaft, are stuck between the parts of motor, affect the working efficiency of blower fan, cause motor to damage, thereby shortened the working life of blower fan; And blower fan is while using under different environment, they are also different to the requirement of height.Install when higher when pipeline, somebody is directly connected blower fan with the pipeline at two ends, and the weight of blower fan is directly born by two pipelines, and pipeline easily excessively causes connection to be become flexible because of stressed, or occurs crack, even fracture damage; And look in addition stool to place blower fan, and easily too high or too low, to install also insecurely, blower fan, easily because vibrations are shifted, is fallen on the ground, and also needs to look for stool, and very trouble just cannot realize the installation to it while thering is no stool at one's side.
Model utility content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of low noise, Wind Volume, and stable, the dustproof defeated blower fan of Wind Volume is firmly installed.
To achieve these goals, the utility model is by the following technical solutions: a kind of Wind Volume defeated blower fan that prevents dust, comprise housing, the left end of described housing is air intake, the right-hand member of housing is outlet air end, is provided with fan and motor in described housing, and described motor comprises the rotating shaft and the motor body that connect fan, described fan comprises blade, the two ends of the described housing flange plate that is respectively threaded; Described blade is equipped with an air inducing short tube near one end of inner walls, and the internal diameter of this air inducing short tube is increased to two ends gradually by centre; Described rotating shaft is provided with a small fan between fan and motor body, and small fan is provided with an Air Filter near one end of motor body.
As preferably, leader is respectively established near flange plate place in the two ends, top of described housing.
As preferably, described blade is three.
In sum, the utlity model has following advantage: air inducing short tube is set and small fan blower effect is good, has strengthened air quantity, reduced noise; Small fan and Air Filter can prevent that the impurity such as dust from entering in motor, have protected motor, extend the working life of blower fan; Described flange plate can arrange the flange plate of multi-group different connecting holes, applied widely, and changes, installs easily.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1, the dustproof defeated blower fan of a kind of Wind Volume, comprise housing 1, the left end of described housing 1 is air intake, the right-hand member of housing 1 is outlet air end, in described housing 1, be provided with fan 2 and motor 3, described motor 3 comprises the rotating shaft and the motor body that connect fan 2, described fan 2 comprises annular cover and blade 21, annular is sheathed on outside rotating shaft, blade 21 is distributed in annular cover external peripheral surface, the two ends of described housing 1 flange plate 6 that is respectively threaded, described flange plate 6 can arrange the flange plate of multi-group different connecting holes, by selecting and the big or small corresponding flange plate of screw on connecting tube, reach the object of stable connection, this setting applied widely, and change, install easily.Described blade 21 is equipped with an air inducing short tube 5 near one end of housing 1 inwall, the internal diameter of this air inducing short tube 5 is increased to two ends gradually by centre, the wind channel that this air inducing short tube 5 forms has good blower effect, the wind that impacts blade 21 can pass from air inducing short tube 5, avoid the loss of air quantity, also avoided wind to impact blade simultaneously and produced noise; In order to make air quantity reach maximum, noise minimum, described blade 21 is three.Described rotating shaft is provided with a small fan 4 between fan 2 and motor body, this small fan 4 is sheathed on machine shaft, and be fixed by latch, small fan 4 is provided with an Air Filter near one end of motor body, the integrally welded structure of this Air Filter and small fan, this small fan is set and has accelerated the transmission speed of wind, strengthen air quantity, and change the moving direction of wind, avoid wind to be blown into from the finedraw between machine shaft and motor body, during for air draft, avoid the impurity such as dust to enter in motor, protected motor, extended the working life of motor; The effect that Air Filter has further strengthened blocks dust is set.
Further, the two ends, top of described housing 1 are respectively provided with leader 8 near flange plate 9 places, and this handle 8 ringwise, and the bottom of ring-shaped handle and the integrally welded structure of housing 1, this handle is set, and convenient gripping in the time changing flange plate, is more prone to dismounting, installation.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all should belong to the scope of the utility model protection.
