Abstract
A wind guide cover body structure for a fan comprises a rear wind guide shell and a plurality of air intake guide pieces, wherein the internal circumference surface of the air intake side is a trumpet-shaped wind guide portion, the air intake guide pieces are arranged at intervals and radially extend to the internal circumference surface of the rear wind guide shell, and the air intake guide pieces and the wind guide portion on the internal circumference surface of the air intake side of the rear wind guide shell form an air intake diversion structure. The wind guide cover body structure has the advantages of simple manufacture and low cost, the diversion structure can converge and guide air flow, lead air flow to be parallelly blown out along the direction of the air intake guide pieces thereof approximately, thereby prolonging air-out distance of air flow and reducing intake air noises.
Description
Technical field
The utility model relates to a kind of wind scooper body structure, relates to a kind of wind scooper body structure that can drive air circulation and convection current that is used for fan especially.
Background technique
Fig. 1 represents general electric fan on the market, described electric fan 10 comprises at least: front fan protecting wire net 101, aft-fan protecting wire net 102, have the impeller 103 of flabellum 1031 and rotating shaft 1032 and in order to the motor 104 of drives impeller, and described front fan protecting wire net 101 only is made up of a plurality of lamettas with the body frame structure of aft-fan protecting wire net 102.Traditional electrical fan 10 utilizes motor 104 drives impeller 103, and fan protecting wire net 101 before and after being provided with, 102 purpose is to avoid the flabellum 1031 because of in the touching rotation to cause danger, and the formation of air-flow is the rotation by flabellum 1031, push and produce from aft-fan protecting wire net 102 outsides extraction air-flow and toward front fan protecting wire net 101, though described air-flow roughly blows out abreast towards the place ahead of electric fan 10, and front fan protecting wire net 101, the exterior structure of aft-fan protecting wire net 102 has the space, many places for the air communication mistake, but still be subject to the interference of surrounding atmosphere, therefore, cause air-flow toward around wandering and wind-force is presented scatter shape, so must just can experience its wind-force in close electric fan 10 certain distances.
In addition, in order to improve the wind-force of electric fan, traditional method is the rotating speed that increases the electric fan flabellum, and still, the rotating speed that increases flabellum will make the side effect that electric fan produces high noisy and causes high power consumption, runs in the opposite direction with advocating environment protection now and energy-conservation trend.
The model utility content
The shortcoming of prior art in view of the above, this novel purpose is to provide a kind of wind scooper body structure that is used for fan, the air-out distance that can prolong air-flow, and lower pneumatic noise.
For reaching above-mentioned and other purpose, the utility model provides a kind of wind scooper body structure that is used for fan, comprising: the back ventilation case, and the inner peripheral surface of its inlet air side is trumpet-shaped air dam; Multi-disc inlet air fairlead, they keep each other at interval and become the radial back ventilation case inner peripheral surface that extends to, and wherein, described inlet air fairlead forms the inlet air flow guide structure with the air dam of the inner peripheral surface of the inlet air side of back ventilation case.
The described wind scooper body structure that is used for fan has the advantage cheaply that reaches simple for production compared to wind scooper body structure of the prior art, and the diversion Design that can utilize the air dam of the described wind scooper body structure that is used for fan and inlet air fairlead is concentrated near the air the flabellum, and adjust the air intake direction of the air extracted from the flabellum rear, and then converge and the flow direction of correcting air-flow air-out, make air-flow along the inlet air fairlead direction almost parallel of flow guide structure blow out, thereby prolong the air-out distance of air-flow, and lower the inlet air noise.

Embodiment
Below by specific instantiation mode of execution of the present utility model is described, the personage who is familiar with this technology can understand advantage of the present utility model and effect easily by the content that this specification disclosed.The utility model can also be implemented in other different mode,, under the prerequisite departing from the technological thought that the utility model disclosed not, can carry out different modifications and change that is.
Fig. 2 A to Fig. 2 D represents the wind scooper body structure 30 that is used for fan of the present utility model, and wherein, Fig. 2 B and Fig. 2 C are respectively the plan view of Fig. 2 A and the partial enlarged drawing of rear view, and Fig. 2 D is the cutaway view Amplified image of inlet air fairlead.Described wind scooper body structure 30 comprises back ventilation case 301 and inlet air fairlead 302.Wherein, described back ventilation case 301 is a housing cylindraceous, and its inlet air side inner peripheral surface is trumpet-shaped air dam 3011, and wherein, the diameter of described horn-like air dam 3011 reduces gradually from inlet air side direction air side.302 of described inlet air fairleads keep at interval, and they become radial extension and are engaged to the air dam 3011 of back ventilation case 301 inner peripheral surfaces.Described inlet air fairlead 302 engages with the inner peripheral surface of back ventilation case 301 with respect to the surface of horn-like air dam 3011, and described inlet air fairlead 302 is in the height maximum at ventilation case 301 inner peripheral surface places, back.Utilize described inlet air fairlead 302 to engage formed inlet air flow guide structure 303 with the air dam 3011 of back ventilation case 301 inner peripheral surfaces, the air intake stream of the air that adjustment is extracted from wind scooper body structure 30 rears, the smooth flat that the inlet air fairlead 302 of arranging in pairs or groups is again had, but focused airflow, and reduce the effect of the pressure loss that the inlet air eddy current caused, and then reduce the generation of inlet air noise.
The wind scooper body structure 30 that is used for fan of the present utility model, can be applied on the rear cover body of various fan, as: upright fan, wall fan and the rear cover body of being located at the ceiling fan of ceiling board, thereby, when the flabellum running of fan, the described wind scooper body structure 30 that is used for fan can be concentrated the air-flow of introducing electric fan, and is converged and put in order and correcting, with the raising air-flow that fan was blown out distance and intensity, and reduce the inlet air noise.
In sum, the diversion Design of air dam and/or inlet air fairlead by described wind scooper body structure of the present utility model, can concentrate near the air of flabellum, and adjust the air intake direction of the air that is extracted at the flabellum rear, and then converge and the flow direction of correcting air-flow air-out, make the air-flow that is blown out have more the craspedodrome of parallelism and height, after making that air-flow blows out from exhaust outlet, its wind speed can be as traditional electrical fan diffusive attenuation apace yet, therefore the air-out distance that can improve wind speed and prolong air-flow.
The foregoing description only is that principle of the present utility model and effect thereof are described illustratively, but not is used to limit the utility model.Rights protection scope of the present utility model should be determined according to the record of claims.
