Abstract
The utility model relates to the field of fans and in particular relates to blades of blower fans. The technical scheme used for solving the technical problems is that the blade of the blower fan comprises a hub and vanes, wherein the blades are uniformly distributed at the outer circumference of the hub; a 45-degree angle is formed between each vane and the hub; and the axial projections of the vanes on the hub are partially overlapped. By adopting the above characteristics, the blade of the blower fan has the beneficial effects that the angle formed between each vane and the axial plane of the hub is designed to 45 degrees and the axial projections of the blades on the hub are partially overlapped, so that the blowing efficiency of the blower fan can be effectively improved.
Description
Technical field
The utility model relates to the blower fan field, relates in particular to a kind of blowing fan blade of blower fan.
Background technique
Blower fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Blower fan is widely used in ventilation, cooling, the dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building; The ventilation of boiler and industrial furnace and air inducing; Cooling and ventilation in the apparatus of air conditioning and domestic electric appliance; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime and Hovercraft and propelling etc.Blower fan is divided into air draught blower fan and blowing blower fan by function.Wherein, the blowing blower fan comprises blowing fan blade, and blowing fan blade generally comprises circular hub, and the excircle of wheel hub evenly distributes and is provided with a plurality of blades, and the angle of blade can affect the blowing efficient of blower fan.Existing many blower fans are because the angle design of the blade on blowing fan blade is unreasonable, and the blowing efficient of the blower fan that is is very low.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of blowing fan flabellum that can effectively improve blower fan blowing efficient.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of blowing fan flabellum, comprise wheel hub and blade, and described blade is evenly distributed on the excircle of wheel hub, and described blade becomes 45 degree angles with the axial plane of wheel hub.
Further, described blade overlaps at the axis projection of wheel hub.
Further, the quantity of described blade is 7.
The utility model adopts the beneficial effect of above-mentioned feature to be: the axial plane angulation of blade and wheel hub is designed to 45 degree, and makes blade overlap at the axis projection of wheel hub, can effectively improve the blowing efficient of blower fan.
Description of drawings
Fig. 1 is the structural representation of a kind of blowing fan flabellum of the utility model.
In accompanying drawing, the list of parts of each label representative is as follows:
1, wheel hub, 2, blade.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
As shown in Figure 1, a kind of blowing fan flabellum of the present utility model comprises wheel hub 1 and blade 2, blade 2 is evenly distributed on the excircle of wheel hub 1, blade 2 becomes 45 degree angles with the axial plane of wheel hub 1, blade 2 overlaps at the axis projection of wheel hub 1, and the quantity of blade 2 is 7.
The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
