Layer steel plate.Super glass wool and porous foam are sound-absorbing material, for converting sound wave kinetic energy to the interior energy of sound-absorbing material, effectively
Noise elimination noise reduction；Outer layer plate belongs to sound insulating layer, the propagation for noise insulation.
Preferably, the noise-reduction case circumferential direction inside is evenly arranged 120 ~ 270 waveform silencing cottons.Waveform silencing cotton
Noise for the fan scroll generation that decays.
Preferably, the normally closed heat release hole of circulating fan and bottom is provided in the gap.Denoiser can effectively drop
Low fan noise, but fan noise sound can be converted into the interior energy of sound-absorbing material and acoustic material, discharge a large amount of heat, it may
Fan operation efficiency is caused to decline.Therefore circulating fan and heat release hole need to be set for waste heat, circulating fan and bottom to be discharged
It is in close state under the usual state of portion's heat release hole, opening when need to radiate.
Compared with prior art, the utility model has the beneficial effect that noise-reduction case for reducing fan scroll production
Raw noise, blimp are used to completely cut off the noise for absorbing that fan scroll and motor generate.Effectively make in guarantee air purifier
Under the premise of with range, fan noise is effectively reduced using the multiple sqouynd absorption lowering noise effect of noise-reduction case and blimp.Together
When the interstitial channels provided with heat transmission, not only ensure that the normal operation of air purifier, but also gap is connecting sound wave not
Continuous interface is propagated, and is provided biggish air layer decaying, is improved the noise reduction effect of the utility model.
