Further, described casing comprises a plurality of air inlets, is provided with woven wire between air inlet and the casing.
Further, the cover inner surface of described casing is provided with one deck sound-absorbing material.
Further, all inner surfaces of described casing are equipped with the deadener of heat-proof quality.
Further, described air inlet, air outlet adopt screw to be connected on the casing, and described ventilation blower adopts Bolt Connection on the space bar of chamber, and described chamber space bar adopts Bolt Connection in casing.
Further, described casing is made substrate with metal sheet, and inner surface posts sound-absorbing porous material, and outer surface is with antiseptic and rustproof lacquer.
Further, described noise elimination structure is the structure of at least two noise elimination cavitys.
Further, described box house has at least four cavitys to form.
Further, described casing is connected with at least five air inlets and an air outlet.
Further, described deadener has at least two kinds of porous enclosed materials.
Further, described casing air inlet and casing connection place are provided with woven wire.
Ventilator in the utility model adopts the air inlet that communicates successively, the air intake noise elimination cavity, the chamber space bar, the variation of air-out noise elimination cavity and air outlet cross section, improved sound deadening capacity greatly, air intake noise elimination cavity and air-out noise elimination cavity inner surface are all with the airtight deadener of porous simultaneously, further improved sound deadening capacity, particularly be provided with the microperforated panel that pastes deadener between air intake noise elimination cavity and the box cover, improved the noise elimination effect of box cover direction greatly, be connected in the casing again after adopting the chamber space bar and ventilation blower connecting, adapt to same casing and used the connection requirement of different ventilation blowers, between air inlet and casing, be provided with woven wire, prevent foreign material, mosquito enters casing, thereby has guaranteed that this device can operate as normal.

The specific embodiment
See also Fig. 1 to Fig. 7, the two-chamber silence type ventilator of present embodiment, comprise have air inlet 1, the casing 14 of air outlet 2 and cover plate 4, be provided with air intake noise elimination cavity 3, air-out noise elimination cavity 7, chamber space bar 10 and ventilation blower 6 in casing 14, air inlet 1, air intake noise elimination cavity 3, ventilation blower 6, chamber space bar 10, air-out noise elimination cavity and air outlet 2 communicate successively.Be provided with damping device 9 between ventilation blower 6 and the chamber space bar 10, this damping device comprises a plurality of bolts 17 that are with rubber blanket 15 and locking spring 16.Be provided with woven wire 8 between air inlet 1 and the air intake noise elimination cavity 3.Part by chamber space bar 10, microperforated panel 5 and casing 14 is enclosed air intake noise elimination cavity 3, and air intake noise elimination cavity inner surface all posts deadener 12,13.Constitute an electric circuit control panel space jointly by the part of air-out noise elimination cavity 7 outer surfaces, chamber space bar 10, box cover 4 and the part of casing 14.Air-out noise elimination cavity 7 inner surfaces all post deadener 13.
Two-chamber silencer ventilator is installed in the indoor furred ceiling of building, room ventilation is mainly undertaken by ventilation blower, when the ventilation blower in the two-chamber silencer ventilator starts, directly drain into outdoor by the air inlet suction through air outlet room air, lasting air draft makes indoor formation certain negative pressure, outdoor air is under indoor suction function, by in external door, the exterior window slit inlet chamber and keep balance, constantly mend indoor, indoor turbid air and constantly drain into outdoor cross-ventilation system thereby formed an outdoor fresh air.Noise elimination process in the two-chamber silence type ventilator mainly is air intake noise elimination cavity and air-out noise elimination cavity, deadener, damping device and microperforated panel enforcement in the casing, deadener be fire-retardant and extinction coefficient greater than the cellular sponge of 0.8 closed pore, change the flowing velocity of air in casing with noise elimination cavity, increase the flow resistance of air in casing, form resonance with microperforated panel and sound wave, to reach the purpose of noise elimination.Adopt damping device, avoided ventilation blower vibrations to casing in running to produce, reduce noisiness.Adopt the chamber space bar, make same casing can adapt to connection with different ventilation blowers.
