Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model air purifier fan assembly is described in further detail.
As shown in Figure 1 to 4, the main upper cover plate 100 of the utility model air purifier fan assembly, lower cover 200, wind guide cover 300 and turbine centrifugal blower fan 400 form.Its middle shell is made up of upper cover plate 100 and lower cover 200, it is the structure of one end open, centrifugal blower 400 is mounted in the cavity of housing, and on wind guide cover 300 fresh air inlet 110 that to be lids be located on upper cover plate 100, air to be entered in housing by the helical form air-guiding hole 310 on wind guide cover 300 and carries out noise reduction by silencing cotton 500.
Air-guiding hole 310 on wind guide cover 300 is that uniform intervals is arranged, and this guarantees air and can be centrifuged blower fan 400 from surrounding by wind guide cover 300 equably and suck and discharge.And air-guiding hole 310 from top to bottom be from small to large in gradual change type design, to guarantee that surrounding air draught effect is greater than central authorities and avoids concentrations in central fresh air inlet place, to reach comprehensive air intake, save thickness and reach comprehensive air intake and make filter screen efficiency utilization; And produce eddy current in the airtight chamber that helical design more can be formed at silencing cotton 500 and wind guide cover 300, allow air can contact fully with silencing cotton 500 whereby, reduce noise and overflow from air inlet, to reach comprehensive air intake and to make silencing cotton 500 efficiency utilization.
Fresh air inlet 110 is arranged on upper cover plate 100, and its position is corresponding with wind guide cover 300.In fresh air inlet 110, be provided with arched baffle plate 120, it is connected with the interior edge of fresh air inlet 110 by support 130.Arched baffle plate 120 and fresh air inlet 110 be coaxial arrange and support 130 for being uniformly distributed, ensure that air enters equably equally, and can prevent silencing cotton 500 from falling into the air inlet of centrifugal blower 400.
Lower cover 200 is also provided with wind deflector 210, wind deflector 210 is arranged around centrifugal blower 400 lower edge, its two ends connect with the inwall of lower cover 200 both sides and the opening of position and housing is relative, after entering the air in housing and being centrifuged blower fan 400 discharge, can scatter to surrounding, the effect of wind deflector 210 be exactly like the air of shell nozzle dorsad stop by wind deflector 210, and to flow towards shell nozzle again along the radian of wind deflector 210.
Further, wind deflector 210 is made up of interconnective arc section 211 and bevel phase 212.Gap between arc section 211 and centrifugal blower 400 is gradual change type design.Gap namely between arc section 211 and centrifugal blower 400 is by the narrow transition structure broadened, and from gap, the less transformation larger to gap is identical with the direction of rotation of turbine centrifugal blower fan, namely first the air thrown away from centrifugal blower 400 enters in less gap and discharges from larger gap, along with the gap between arc section 211 and centrifugal blower 400 becomes large gradually, make the speed goes of air slow, going out speed and can not produce more noise finally when reaching outlet.
In addition, the bevel phase 212 of wind deflector 210 opposite side is connected with lower cover 200 opposite side inwall, when from gap, larger end flows out air, there is the air of part can be back to lower cover 200 opposite side, at this moment, bevel phase 212 just can by the air " bounce-back " of backflow, and the angle α between the bevel phase 212 of wind deflector 210 and lower cover 200 sidewall is less than or equal to 45 degree, the air of backflow is allowed to rebound towards the opening direction of housing, air can evenly be disengaged from air outlet, directly bounce-back is avoided to make wind direction cause situation about liquidating towards side adverse current on the contrary to the inwall of lower cover 200.
The utility model air purifier fan assembly designs the wind guide cover of a circular lid above fresh air inlet, design multiple spirality fresh air inlet above, middle little four sides is large, eddy current is produced in the airtight chamber formed in housing whereby, to reach comprehensive air intake, save thickness and reach comprehensive air intake and make filter screen efficiency utilization.And design spiral wind deflector 210 at the lower edge of lower cover centrifugal blower, to allow wind direction concentrate on one end air-out.Overflowing from air inlet for reducing noise in addition, installing silencing cotton additional in air inlet.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
