Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of noise reducing brethaid inside and outside main chamber in the present invention;
Fig. 2 is the structural representation of noise reducing brethaid inside and outside concubine in the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining.
Referring to Fig. 1 and Fig. 2, a kind of indoor and outdoor noise reducing brethaid provided by the invention, including noise reducing brethaid 1 inside and outside main chamber and noise reducing brethaid 2 inside and outside concubine, inside and outside main chamber, inside and outside noise reducing brethaid 1 and concubine, noise reducing brethaid 2 all includes sound-absorbing breather chamber 3, and inside and outside main chamber, the sound-absorbing breather chamber 3 side connection of noise reducing brethaid 1 is provided with ventilation blower fan 4.
When room air needs to take a breath, inside and outside main chamber, the ventilation blower fan 4 of noise reducing brethaid 1 starts, just the air of indoor anoxia (or contaminated) can be discharged to outdoor, the sound-absorbing breather chamber 3 of noise reducing brethaid 1 inside and outside main chamber, air is made to be discharged to the decay of produced noise energy, noise reduction during outdoor.
Now, indoor and outdoor exists for a pressure reduction, and fresh air passes through inside and outside concubine in sound-absorbing breather chamber 3 inlet chamber of noise reducing brethaid 2, and then realizes indoor-outdoor air exchange, and reduces noise.
So by noise reducing brethaid 1 inside and outside main chamber and the cooperation of noise reducing brethaid 2 inside and outside concubine, indoor-outdoor air effectively can being swapped, noise can be reduced again. When mounted, body of wall diverse location is made a call to two applicable holes, noise reducing brethaid 2 inside and outside noise reducing brethaid 1 and concubine can be loaded inside and outside main chamber.
In the present embodiment, sound-absorbing breather chamber 3 includes casing 31, casing 31 is axially respectively arranged at two ends with the first passage 32 and the second passage 33, casing 31 inner chamber between first passage 32 and the second passage 33 constitutes outer venting cavity 34, in outer venting cavity 31, in axial direction concentric gap is provided with interior venting cavity 35, interior venting cavity 35 includes the first ventilating part 351 and the second ventilating part 352, first ventilating part 351 and the second ventilating part 352 all offer circulation ventilating hole 353, the circulation ventilating hole 353 of the first ventilating part 351, ventilate in opposite direction with the circulation ventilating hole 353 of the second ventilating part 352.
So, as it is shown in figure 1, when using noise reducing brethaid 1 inside and outside main chamber, ventilation blower fan 4 is taken a breath, contaminated air initially enters the first ventilating part 351, discharges (namely completing air circulation outside in venting cavity 34) from the second ventilating part 352 afterwards. So that the air discharged (enters and after discharging circulation ventilating hole 353 through repeatedly volume-diminished (moment being discharged in circulation ventilating hole 353), amplification, outside venting cavity 34 or when running in the inner chamber of ventilating part) and go for a stroll (whole cyclic process), the noise energy making various frequency decays, and reaches the purpose of noise reduction.
As shown in Figure 2, when using noise reducing brethaid 2 inside and outside concubine, first fresh air enters the second ventilating part 352 of interior venting cavity 35 from the second passage 33, discharges from the first ventilating part 351 afterwards, complete the fresh air noise reduction when entering, described in principle such as epimere.
In the present embodiment, outer venting cavity 34 is more than one group with interior venting cavity 35. Purpose is in that, can need to carry out quantitative adjustment according to use, when careat is relatively larger, greater number of compound mode can be adopted, reach good noise reduction, when careat is smaller, small number of compound mode can be adopted, or directly adopt single combination, reach to save the purpose of cost.
In the present embodiment, being provided with outer venting cavity segmentation support 311 between adjacent outer venting cavity 34, outer venting cavity segmentation support 311 one end is connected on the inwall of casing 31, and the other end is connected between adjacent interior venting cavity 35. Purpose is in that, conveniently carries out the arrangement of the outer venting cavity 34 of many groups and interior venting cavity 35, and production cost is relatively low.
In the present embodiment, inside and outside concubine in noise reducing brethaid 2, the first passage 32 place of casing 31 is provided with cover plate 5. Purpose is in that, improves the degree of convenience installed.
In the present embodiment, the junction of casing 31 and ventilation blower fan 4/ cover plate 5, the junction of interior venting cavity 35 and ventilation blower fan 4/ cover plate 5, and the junction of outer venting cavity segmentation support 311 and interior venting cavity 35, it is equipped with sealing ring 6. Purpose is in that, it is prevented that the air leakage when noise reduction, affects noise reduction.
In the present embodiment, ventilation blower fan 4 is intelligence self-starting blower fan. When intelligence self-starting aerator supervision needs forced ventilation to room air, automatically starting, improves the degree of convenience used. Intelligence self-starting blower fan is prior art, therefore does not repeat them here. Certainly, adopt common ventilation blower fan also can, the factor such as power, rotating speed, can according to using environment carry out corresponding adjustment.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-described embodiment, and all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention. It should be pointed out that, for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be regarded as protection scope of the present invention.
