Embodiment

Core of the present utility model is the drainage pipe assembly providing a kind of excellent noise reduction effect and being convenient to arrange.

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only the utility model part embodiment, instead of whole embodiments. Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Please refer to Fig. 4 to Fig. 6, Fig. 4 is the drainage pipe assembly front view in the utility model specific embodiment, and Fig. 5 is the drainage pipe assembly left view in the utility model specific embodiment, and Fig. 6 is the drainage pipe assembly vertical view in the utility model specific embodiment.

In a kind of specific embodiment scheme, the utility model provides a kind of drainage pipe assembly, comprise drainage tube pipe body 1 and lay respectively at inlet mouth 3 and the air outlet 2 at drainage tube pipe body 1 two ends, drainage tube pipe body 1 is communicated with resonator cavity 5 by drainage tube arm 4, and the axis of drainage tube arm 4 and the axis being parallel of inlet mouth 3 are arranged.

The installation position of the drainage tube arm 4 connected on drainage tube pipe body 1 has been changed by the utility model, compared to the decoration form of drainage tube arm and inlet mouth axes normal in prior art, the axis designs of drainage tube arm 4 is that the axis being parallel with inlet mouth 3 is arranged by the utility model, namely drainage tube arm 4 is positioned opposite with junction and the inlet mouth 3 of drainage tube pipe body 1, therefore, when air-flow enters drainage tube, air just can directly import and rush in resonator cavity 5, more air is made directly to enter in resonator cavity 5, such that it is able to more effectively eliminate the low-frequency noise of inlet system.

It should be noted that, this scheme also changes the structure of resonator cavity 5, concrete, and the noise elimination volume of resonator cavity 5 is increased by the utility model, and physical dimension is in horizontal shortening, longitudinally growth. The horizontal length of resonator cavity of the prior art is 350mm, is longitudinally highly 76mm, after the structure of resonator cavity 5 is optimized by the utility model, it may be preferred that the horizontal length of resonator cavity 5 is 185mm～350mm, is longitudinally highly 76mm～130mm. After the cavity volume of resonator cavity 5 increases, noise elimination frequency range is widened, and therefore soundproof effect is effectively improved.

Further, in this specific embodiment scheme, the length of resonator cavity 5 is 185mm, is highly 130mm. So arranging, the noise elimination volume of resonator cavity 5 is effectively increased, and noise elimination frequency range is widened, further, while improving soundproof effect, the change of resonator cavity 5 physical dimension also avoid the Assembly Interference of itself and peripheral component, therefore, more it is convenient to the mounting arrangements of engine and other parts.

In order to improve noise elimination noise reduction effect further, it may be preferred that the medullary ray of the axis of drainage tube arm 4 with drainage tube pipe body 1 is designed to crossing layout by this scheme. So arranging, drainage tube arm 4 just faces inlet mouth 3 with the junction of drainage tube pipe body 1, such that it is able to be convenient to more air to enter resonator cavity 5.
