Description
Technical field
The utility model belongs to mechanical engineering field, especially relates to a kind of portable Wind Volume blower fan.
Background technique
In existing blower fan, be mostly just, after wind is sucked by intake grill, by blower fan, wind is sent by exhaust outlet.When going for larger wind speed, wind-force can only be increased by tuning up rotation speed of fan.And when fan speed has tuned up maximum, and when still not reaching desirable wind speed, just helpless.Further, because blower fan needs obtain larger air quantity, therefore intake grill usually can be comparatively large, and when intake grill is opened in housing sidepiece, moving and carrying for blower fan, can only hold bottom by both hands and come, inconvenience very.
Model utility content
The utility model, in order to overcome the deficiencies in the prior art, provides the portable Wind Volume blower fan that simple, the defeated air quantity of a kind of structure is large.
To achieve these goals, the utility model is by the following technical solutions: a kind of portable Wind Volume blower fan, comprise housing, wind wheel, enclosure interior is with cavity, described housing sidepiece offers intake grill, case top offers exhaust outlet, described wind wheel is placed in cavity, for the wind of air inlet is delivered to exhaust outlet, described exhaust outlet is connected with defeated wind passage, described case top offers for placing handle standing groove, this standing groove top is provided with two for taking out the circumferential notch of handle, described standing groove two bottom sides portion all offers receiving hole, described handle both side ends stretches out formation flange, this flange is placed in described receiving hole, and can rotate relative to receiving hole, described wind wheel comprises central shaft and flabellum, this wind wheel central shaft end sleeve is provided with a guide ring, this guide ring inwall is tiltedly installed with flange vertically, guiding gutter is formed between two flanges, described wind wheel flabellum end wall fits in inner walls.
Further, intake grill is extended in described guide ring end, and this guide ring is horn-like setting, horn-likely arranges increase incoming air area, thus increases the defeated air quantity of blower fan.
Further, bottom described Blower Housing, be connected with antivibration pad, make landing of blower fan more stable, the setting of antivibration pad, noise during blower fan work can be alleviated.
In sum, the utility model has the following advantages: this blower fan structure is simple, and work component are few, cost-saving, and operating noise is little.Arrange handle, only need hold handle when blower fan is moved can operate, convenient and swift; Guide ring is arranged so that air output increases, thus increases the defeated air quantity of blower fan; And guide ring is sheathed on wind wheel central shaft, drives it to rotate, energy saving by the rotation of wind wheel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view at B place in Fig. 1.
Fig. 3 is the structural representation of wind wheel.
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, clear, complete description is carried out to the technological scheme in the utility model embodiment.
As Figure 1-3, a kind of portable Wind Volume blower fan, comprises housing 1, wind wheel 2, and housing 1 inner band has cavity, and described wind wheel 2 is placed in this cavity.Wind wheel 2 is made up of central shaft 21 and the flabellum 22 connected on center shaft, and the end wall of this wind wheel flabellum 22 all fits in the inwall of housing 1.Make to rotate in the process of defeated wind at wind wheel, farthest wind can be transported to exhaust outlet place, in course of conveying, the wind of a part can not be missed because of there is gap between flabellum and housing.Further, be arranged with a guide ring 5 in the outer end of wind wheel central shaft 21, this guide ring 5 inwall is tiltedly installed with vertically between multiple flange 51, two flange 51 and forms guiding gutter 52.Intake grill 11 is extended in described guide ring 5 end, and is set to horn-like setting.When wind wheel rotates, guide ring 5 can be driven together to rotate, because the flange 51 on guide ring 5 is obliquely installed, therefore after guide ring 5 rotates, can eddy flow be formed, the air of outside be attracted to come, enters in housing by guiding gutter 52, thus strengthen the air output of blower fan, also increase the defeated air quantity of blower fan.Further, the rotation of guide ring 5 is driven by wind wheel 2, does not need other machine to drive, saves energy consumption.And trumpet-shaped setting increases the area of contact of guide ring and outside air, further increase air output.
The sidepiece of housing 1 offers intake grill 11, and housing bottom offers exhaust outlet, by wind wheel 2, the wind at intake grill 11 place is delivered to exhaust outlet, is connected with a defeated wind passage 3 at exhaust outlet place.Offer one the shape of standing groove and size are all identical with handle for placing the standing groove 12 of handle 4 at the top of housing 1, and so in the course of the work, handle 4 can embed standing groove 12, arbitrarily can not rock because of the shake of blower fan work.The two bottom sides portion of described standing groove 12 all offers receiving hole 122, and described handle both side ends stretches out and forms flange 41, and this flange 41 is placed in described receiving hole 121, and can rotate relative to receiving hole 121.This standing groove 12 corresponds to the position of grip, offers two for taking out the circumferential notch 121 of handle 4.When handle is placed in this standing groove 12, two fingers just can be entered in this circumferential notch 121, handle has been plucked out.
Further, be also provided with antivibration pad in the bottom of Blower Housing, make landing of blower fan more stable, and noise when can alleviate blower fan work.
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 obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
