Abstract
The utility model belongs to a dynamic light shielding device which consists of a driving blade and a driven blade driven by air of the driving blade; the driven blade is arranged at the air blowing-out direction end of the driving blade and the rotating direction of the driven blade is opposite to that of the driving blade, and the driving blade is fixed on a motor shaft. In the utility model, light can be shielded effectively, the effect of shielding light but not shielding wind can be realized, and the dynamic light shielding device has the advantages of simple structure, low using cost and good using effect.
Description
Technical field
The utility model belongs to a kind of dynamic light rain shield device.
Background technique
As everyone knows, the fan application area is wider, and it is mobile that fan mainly produces air by the rotation of driven by motor blade, to realize the replacing to indoor air.During the rotation of driven by motor blade, because the space light between the blade can pass the blade of rotation from an end of blade and shine the other end, common this phenomenon can not influence the use of fan, but then require to stop the generation of this phenomenon at some special dimension, promptly require air stirred by blade and flow, but light can not shine the other end from blade one end.As an end have an injury human body but have the ultraviolet of bactericidal effect, or other place of covering light and requiring to ventilate.But do not have corresponding apparatus at present, often realize above-mentioned requirements, but multiple bending pipeline takes up room greatly with multiple bending pipeline, the user cost height, the construction complexity, using effect is not good.
Summary of the invention
The purpose of this utility model provides a kind of dynamic light rain shield device, can shield light effectively, can realize the not effect of choke of resistance light, and it is low to have simple structure and user cost, the advantage that using effect is good.For this reason, the utility model adopts mainly to be made up of motor and active blade, constituted by an active blade and a passive blade that driven by active blade wind, passive blade is to be positioned at active blade to blow out wind direction end and the passive blade opposite with the active blade sense of rotation, and active blade is fixed on the motor shaft.Described active blade and passive blade concentric.Described passive blade axle is located at active blade and blows out on the motor shaft of wind direction end.Described passive blade axle is located at active blade and blows out on the support shaft of wind direction end.The said structure design has realized the purpose of this utility model.
Advantage of the present utility model can shield light effectively, can realize the not effect of choke of resistance light, and it is low to have simple structure and user cost, and using effect is good.

Embodiment
As depicted in figs. 1 and 2, a kind of dynamic light rain shield device mainly is made up of motor 4 and active blade 5.Constituted by an active blade and a passive blade that driven by active blade wind, passive blade 6 is to be positioned at active blade to blow out wind direction end and the passive blade opposite with the active blade sense of rotation, active blade is fixed on the motor shaft 3, described active blade and passive blade concentric.Described passive blade axle is located at active blade and blows out on the motor shaft of wind direction end.Described passive blade axle is located at active blade and blows out on the support shaft 12 of wind direction end.
As shown in Figure 1, a kind of dynamic light rain shield device is made of an active blade and a passive blade that driven by active blade wind, and passive blade 6 is to be positioned at active blade to blow out wind direction end and the passive blade opposite with the active blade sense of rotation.Active blade is fixed on the motor shaft 3, and motor shaft is by driven by motor.The passive blade axle is located at active blade and blows out on the motor shaft of wind direction end, on this motor shaft, pass through fixing bolt 9 fixedly fixed axle sleeve 8 and baffle plate 7, rigid bearing 2 inner rings on the fixed axle sleeve, rigid bearing outer ring fixedly moving axis interlocks part 10, and passive blade is fixed on moving axis by clamping bolt 1 and interlocks on the part.The coaxial setting of active blade and passive blade.
As shown in Figure 2, obviously, passive blade also can axle be located at active blade and blows out on the support shaft 12 of wind direction end.Support shaft is fixing by fixing bolt and support 11.The other end of support and motor or corresponding fixing tube are fixed and are got final product.Described active blade and passive blade concentric, i.e. support shaft and motor shaft concentric.All the other are identical with the described structure of Fig. 1, so be not repeated.
During use, motor shaft drives the active blade rotation, the moving passive blade opposite spin of the wind that the active blade rotation produces, and effectively shielded from light realizes the not effect of choke of resistance light.
In a word, the utility model can shield light effectively, can realize the not effect of choke of resistance light, and it is low to have simple structure and user cost, the advantage that using effect is good.
