Abstract
The utility model discloses a novel axial flow wind wheel which comprises an upper cover, fan blades and a base. The upper cover, the fan blades and the base are connected in sequence, the upper cover, the base and the fan blades are in ultrasonic welding, a rotary shaft is arranged in the middle of the base, and the fan blades are connected in sequence around the inner wall of the wind wheel. The fan blades in the wind wheel are formed at one time, the manufacturing cost of one-time forming is greatly lowered relative to that of original split forming, the advanced injection molding gas auxiliary technology is adopted for forming, the middle portion is hollow, the gram weight in hollow design is reduced by 40 percent relative to that of original products, overall forming is firmer than the original product structure, the service life is long, noise is low, seams do not exist, materials and labor cost are saved, deformation is avoided, corrugation design is adopted in the edge, and the rotating resistance of the fan blades can be reduced.
Description
Technical field
The utility model belongs to a kind of design field of wind wheel, especially a kind of novel axial-flow windwheel.
Background technique
Fan blade is in the market solid, and materials cost is high, is formed by 2 merging, also needs artificial merging, and middle merging place has gap, and in use, noise is large, also easily distortion.Axial-flow windwheel is because air quantity is large, noise is low, pressure is low, be widely used in air conditioner and various ventilating heat dissipating environment, efficiency and the noise effect of the design quality of axial-flow windwheel to blower fan is very large, along with the raising of country to air-conditioning efficiency, require also higher to the fan efficiency of heat transmission, require the noise of wind wheel low, efficiency is high.
Model utility content
The purpose of this utility model is to provide a kind of novel axial-flow windwheel, to solve the problems such as noise is large.
For achieving the above object, the utility model provides following technological scheme:
A kind of novel axial-flow windwheel, comprises the upper cover connecting successively, fan blade, and base.
As further scheme of the utility model: carry out joint forming by rotating shaft and nut between described upper cover and base.
As further program of the utility model: described fan blade is fixedly mounted on the sidewall between upper cover and base, and fan blade face adopts to tilt to install, thereby reaches using effect optimization.
As further scheme of the utility model: the blade between described upper cover and base is to adopt hollow design, when fan blade operation, can reach the weight of the wind wheel that the air flow stream general character strengthens and greatly alleviate most itself.
As further program of the utility model: describedly connect successively seven with fairshaped fan blade on the sidewall of wind wheel, fan blade edge is provided with some sawtooth.
Compared with prior art, the beneficial effects of the utility model are: fan blade once-through, and than in the past, more split type moulding manufacture cost reduced greatly in once-through, adopt the moulding of leading injection moulding gas auxiliary process, centre is hollow, hollow, and hollow design ratio in the past product alleviates grammes per square metre 40%, and global formation is than product structure was firm in the past, life-span is long, noise is little, seamless, saves material and cost of labour, can not be out of shape, edge adopts gauffer design can reduce blade rotation resistance.
Brief description of the drawings
Fig. 1 is plan view of the present utility model;
Fig. 2 is side view of the present utility model.
In figure: 1-upper cover, 2-fan blade, 3-base.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, 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 belong to the scope of the utility model protection.
Embodiment 1
Refer to Fig. 1 and Fig. 2, in the utility model embodiment, a kind of novel axial-flow windwheel, comprise the upper cover 1 connecting successively, fan blade 2, base 3, described upper cover 1 and fan blade base 3 adopt ultrasonic welding, and the neutral position of described base 3 is provided with rotating shaft, and described fan blade 2 connects around wind wheel inwall successively.
Embodiment 2
Refer to Fig. 2, on embodiment 1 basis, improve, three of described upper cover and blade bases are by ultrasonic welding moulding, fan blade is fixedly mounted on the sidewall between upper cover and base, and fan blade face adopts and tilts to install, thereby reach using effect optimization, blade between upper cover and base is to adopt hollow design, in fan blade when operation, can reach the weight of the wind wheel that the air flow stream general character strengthens and greatly alleviate most itself, and on the sidewall of wind wheel, connects successively seven with fairshaped fan blade.
Working principle of the present utility model is: fan blade once-through in the utility model; mainly protection is fan blade, and than in the past, more split type moulding manufacture cost reduced greatly in once-through, adopted the moulding of leading injection moulding gas auxiliary process; centre is hollow, hollow; global formation is than product structure was firm in the past, and the life-span is long, and noise is little; seamless; save material and cost of labour, can not be out of shape, edge adopts gauffer design can reduce blade rotation resistance.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the utility model.Any reference character in claim should be considered as limiting related claim.
In addition, be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, and the technological scheme in each embodiment also can, through appropriately combined, form other mode of executions that it will be appreciated by those skilled in the art that.
