Description
Technical field
The utility model belongs to mechanical engineering field, especially relates to a kind of blower fan.
Background technique
In existing blower fan transmitting procedure, easily produce inclined to one side wind, this inclined to one side wind impact housing has not only reduced the working efficiency of blower fan, also easily produces very large noise, the method that tradition reduces noise is, in fan edge, projection is set, its weak effect, also easily weakens wind-force, reduces the defeated air quantity of blower fan; And housing comprises upper shell and lower shell body, when maintenance motor, need tear upper shell open and could motor be keeped in repair or be safeguarded; And the volume of housing is large, very heavy again, remove very effort, and moving process is easily broken housing; Common people bother because of maintenance process, and the maintenances such as the dedusting of blower fan not being carried out cause shorten the working life of motor.
Model utility content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of noise little, and air quantity is large, the blower fan of easy-maintaining.
To achieve these goals, the utility model by the following technical solutions: a kind of blower fan, 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; Described motor comprises the rotating shaft that connects fan, and described housing is provided with the scaffold for fixed electrical machinery, and outlet air end top is provided with vertically for scaffold top and passes, and the long strip recess moving left and right; Scaffold top is the slide plate of salable long strip recess, and slide plate is provided with the U-shaped frame for settling motor near exhaust outlet one end; Described long strip recess both sides of the edge and slide plate contacting point, respectively establish row's ball, and the upper surface of slide plate is provided with a dismountable handle near air intake place; What described fan outer was arranged with an annular subtracts sound cover, described in subtract sound cover internal surface be provided with projection, this top and slide plate that subtracts sound cover removably connects.
As preferably, described in subtract sound cover outer surface near described inner walls setting.
As preferably, described in subtract sound cover top and be vertically provided with a connecting rod, the end of connecting rod is threaded with slide plate lower surface.
In sum, the utlity model has following advantage: what band projection was set subtracts sound cover, has reduced noise, wind is play the guiding role simultaneously, has improved the air output of blower fan; Be provided with handle, conveniently move slide plate to air-out direction, can keep in repair motor, safeguard, operating process is simple, convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is plan view of the present utility model.
Fig. 3 is side structure schematic diagram 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 Figure 1-3, a kind of blower fan, comprises housing 1, and the left end of described housing 1 is air intake 11, and the right-hand member of housing 1 is outlet air end 12, is provided with fan 2 and motor 3 in described housing 1; Described motor 3 comprises the rotating shaft that connects fan 2, described housing 1 is provided with the scaffold 4 for fixed electrical machinery 3, outlet air end 12 tops are provided with long strip recess 5 vertically, and scaffold 4 tops pass long strip recess 5, and described scaffold 4 can move left and right along this long strip recess 5; The top of scaffold 4 is the slide plate 6 of salable long strip recess 5, and this slide plate 6 is slightly larger than long strip recess 5, and then can seal long strip recess, and long strip recess 5 edges and slide plate 6 are fixed by the first screw; Slide plate 6 is provided with the U-shaped frame 7 for settling motor 3 near exhaust outlet one end, and the bottom of the bottom of motor 3 and U-shaped frame 7 removably connects by bolt; Described long strip recess 5 both sides of the edge and slide plate 6 contacting points, respectively establish row's ball 8; Ball is set can light mobile slide plate, and the upper surface of slide plate 6 is provided with a dismountable handle 61 near air intake 11 places, is provided with handle and facilitates mobile slide plate.
When use, utilize handle 61 that slide plate 6 is moved to air-out direction, motor 3 passes housing 1, just can keep in repair motor, safeguard; Travelling backwards slide plate 6, to the bottom of long strip recess, is realized the sealing to long strip recess, then tightens the first screw, fixes with the sealing of housing 1 thereby realize slide plate 6; Be provided with slide plate 6, move slide plate 6 just can keep in repair motor, safeguard to air-out direction, operating process is simple, and maintenance easily, is conveniently regularly safeguarded it, and then extended the working life of motor; When maintenance, also can prevent from damaging housing, and this blower fan is simple in structure, is convenient to realize.
The outer sound that subtracts that is arranged with an annular of described fan 2 overlaps 9, the described internal surface that subtracts sound cover 9 is provided with inhomogeneous projection, this top and slide plate 6 that subtracts sound cover 9 removably connects, this is set and subtracts sound cover, when inclined to one side wind impacts when subtracting sound and overlapping 9, its inner asymmetric projection can be directed to inclined to one side wind on normal orbit, has not only reduced noise, also increase air quantity simultaneously, and then improved the working efficiency of blower fan.Concrete, described in subtract sound and overlap 9 appearances near described housing 1 inwall, this is arranged on to subtract between sound cover outer surface and housing and forms little air channel, has further increased air quantity, also can not affect to subtract sound and overlap inner air quantity simultaneously.And will subtract sound cover 9 and be connected with scaffold 4, and conveniently clear up and change subtracting sound cover.
Further, described in subtract sound and overlap 9 tops and be vertically provided with a connecting rod, the end of connecting rod is threaded with slide plate 6 lower surfaces, this arranges easy installation and removal, easily realizes; In other embodiments, can directly overlap the lower surface of 9 welded top at slide plate by subtracting sound, or directly will subtract sound set upper side and be fixed on slide plate 6 lower surfaces by the second screw.
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.
