The purpose of this utility model is to be achieved through the following technical solutions:
The front end of a kind of high-efficient noise-reducing muffler, including noise reduction cylinder, the noise reduction cylinder is provided with air inlet pipe, its rear end
It is provided with escape pipe, multiple partitions are provided in the hush pipe body so that noise reduction cylinder is separated into several noise reduction chambers, institute
The radial direction that partition is stated along noise reduction cylinder arranges, is provided with quieter material on the inner wall of the noise reduction chamber, on every piece of partition
It is provided with the hush pipe for being connected to adjacent noise reduction chamber, offers several bloops on the tube wall of the hush pipe.
As a kind of preferred embodiment of the utility model, the air inlet pipe protrudes into hush pipe body and extension to the back-end, disappears
The inlet end of the hush pipe of front end is located at the front end of air inlet pipe outlet side in sound cylinder；Adopt the structure design, Neng Gouyan
Long air-flow improves the erasure effect of quieter material in the silencing cavity indoor time.
As a kind of preferred embodiment of the utility model, the escape pipe is protruded into hush pipe body and forward end extends, and is disappeared
The outlet side of the hush pipe of rearmost end is located at the rear end of escape pipe inlet end in sound cylinder；Adopt the structure design, Neng Gouyan
Long air-flow improves the erasure effect of quieter material in the silencing cavity indoor time.
As a kind of preferred embodiment of the utility model, adjacent hush pipe parallel arrangement；The design of parallel arrangement, Neng Gouyan
Long air-flow improves the erasure effect of quieter material in the silencing cavity indoor time.
As a kind of preferred embodiment of the utility model, adjacent hush pipe includes being located at the first hush pipe of front end and being located at
Second hush pipe of rear end, the outlet side of first hush pipe are located at the rear end of the second hush pipe inlet end；Using such knot
Structure design, is able to extend air-flow in the silencing cavity indoor time, improves the erasure effect of quieter material.
As a kind of preferred embodiment of the utility model, the quieter material is noise elimination cotton.
As a kind of preferred embodiment of the utility model, the noise elimination cotton is super glass wool.
The beneficial effects of the utility model are that a kind of high-efficient noise-reducing muffler is simple, easily manufactured with structure, makes
Make it is at low cost, the characteristics of good muffling effect.
Detailed description of the invention
Fig. 1 is a kind of schematic perspective view of high-efficient noise-reducing muffler of the utility model；
Fig. 2 is a kind of schematic diagram of internal structure of high-efficient noise-reducing muffler of the utility model.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.It can manage
Solution, embodiment described herein are used only for explaining the utility model, rather than the restriction to the utility model.
It please refers to shown in Fig. 1 and Fig. 2, Fig. 1 is a kind of schematic perspective view of high-efficient noise-reducing muffler of the utility model；
Fig. 2 is a kind of schematic diagram of internal structure of high-efficient noise-reducing muffler of the utility model.
In this present embodiment, a kind of high-efficient noise-reducing muffler, including noise reduction cylinder 1, the front end setting of the noise reduction cylinder 1
There is air inlet pipe 2, its rear end is provided with escape pipe 3, and 2 partitions 4 are provided in the noise reduction cylinder 1 so that noise reduction cylinder to be separated into
3 noise reduction chambers 5, the partition 4 is arranged along the radial direction of noise reduction cylinder 1, is provided with and is disappeared on the inner wall of the noise reduction chamber 5
Sound cotton 6, the noise elimination cotton 6 are super glass wool, and the noise reduction for being connected to adjacent noise reduction chamber 5 is provided on every piece of partition 4
Pipe 7, adjacent hush pipe 7 are arranged in parallel, and in the present embodiment, hush pipe 7 is arranged one on the other, and in adjacent hush pipe 7, front end disappears
The outlet side of sound tube 7 is located at the rear end of 7 inlet end of rear end hush pipe, and then can extend the time in noise reduction chamber 5, and raising disappears
Audio fruit, offers several bloops 8 on the tube wall of the hush pipe 7, the air inlet pipe 2 protrude into noise reduction cylinder 1 and to
Rear end extends, and the inlet end of the hush pipe 7 of front end is located at the front end of 2 outlet side of air inlet pipe, the escape pipe in noise reduction cylinder 1
3 protrude into noise reduction cylinder 1 and forward end extends, in noise reduction cylinder 1 outlet side of the hush pipe 7 of rearmost end be located at escape pipe 3 into
The rear end at gas end.
After air-flow enters noise reduction cylinder 1 by air inlet pipe 2, a part is absorbed by the noise elimination cotton 6 in front end noise reduction chamber 5 and is made an uproar
