It should be understood that 120 static pressure coefficient of through-flow fan blade is low, cause inlet outlet pressure differential small.It is hindered when air outlet 112 exists
When power component 130, easily causes fan blade 120 and pressure instability occur and unstable abnormal sound is caused to occur.It makes an uproar to reduce this
Sound, Normal practice is to improve 120 revolving speed of fan blade, so that increasing blower fan structure 100 exports static pressure.Moreover, in order to which more flexible disappears
Except the noise, the utility model is provided with telescopic wind-blocking mechanism 140 in casing mechanism 110.Wind-blocking mechanism 140 under high revolving speed
Accommodating chamber is retracted, air duct performance is not influenced.When revolving speed decline, static pressure shakiness, by the way that wind-blocking mechanism 140 is gradually stretched out shell
Mechanism 110, and with the rule that the reduction of revolving speed, wind deflector 141 gradually extend, it is stringent to eliminate unstable accordatura.
Eliminate the principle of unstable accordatura are as follows: since 100 size of blower fan structure is smaller, internal structure is compact, air inlet direction limit
System, there are the reasons such as obvious resistance elements 130,112 air-flows of air outlet to be biased to 116 direction of volute tongue for air outlet 112, causes under
It swims section 1142 and apparent be vortexed nearby occurs.When 120 revolving speed of fan blade is relatively low, 120 static pressure of fan blade is unstable, 112 air-flow of air outlet
Cannot be by the vortex stabilization in the region, which is easy upstream section 1141 and develops and enter the main through-flow area of fan blade 120, from
And mainstream is upset, cause the flow instabilities of 112 air-flow of air outlet, to generate unstable accordatura.By in the upstream of spiral case 114
Wind-blocking mechanism 140 is added between section 1141 and tract 1142, the vortex upstream development of section 1141 must just keep out the wind across this
Mechanism 140, and 140 end air-flow dynamic pressure of wind-blocking mechanism is apparently higher than 114 wall area of spiral case, so that increasing vortex crosses gear
The difficulty of blower structure 140, the control that will firmly be vortexed ensure that the smooth of mainstream, eliminate unstable accordatura in the region.
