Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model；
Fig. 2 is the utility model sound-deadening and noise-reducing chamber cross-sectional schematic diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figs. 1-2, the utility model provides a kind of technical solution:
A kind of sound insulation and noise reduction ventilator, including shutter 1, porous insulation plate 3, sound-deadening and noise-reducing chamber 4, blower 5, expansion gummosis
Pad 61, quieter material 8, noise reducing plate 7；Shutter 2 is detachably fixed with sound-deadening and noise-reducing chamber 4 and connect；3 bolt of porous insulation plate connects
It is connected to 2 inside of shutter；Blower 5 is placed in sound-deadening and noise-reducing chamber interior by fixed frame 51, and blower 5 and sound-deadening and noise-reducing chamber 4 are logical
It crosses and expands the noise reduction air duct 6 that gummosis pad 61 forms sealing；Quieter material 8 is laid on 4 inner wall of sound-deadening and noise-reducing chamber；Noise reducing plate 7 be in by
What is gradually reduced ladder-like is fixed on inside sound-deadening and noise-reducing chamber 4.
The noise reduction air duct 6 that blower 5 and sound-deadening and noise-reducing chamber 4 are formed by expanding gummosis pad 61, is reduced since fluid vibration produces
