Description

Technical Field

[0001] This utility model belongs to the technical field of motorcycle parts, and in particular relates to a round hole type motorcycle muffler. Background Technology

[0002] The motorcycle muffler is a key component of a motorcycle, its main function being to reduce exhaust noise, thereby improving the riding experience and safety. Its working principle involves the high-temperature, high-pressure exhaust gas from the engine repeatedly circulating through porous pipes and baffles within the muffler, gradually attenuating the noise.

[0003] Because conventional car mufflers simply meander through the channel and achieve noise reduction through holes or partitions, the noise reduction efficiency of conventional motorcycle mufflers is relatively low due to the short noise reduction path within the same space.

[0004] Therefore, we propose a circular hole-type motorcycle muffler to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low noise reduction efficiency of conventional motorcycle mufflers, and to propose a circular hole type motorcycle muffler.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A circular perforated motorcycle muffler includes an air guide shell. Inside the air guide shell are a first perforated muffler and a second perforated muffler. An exhaust hood is located inside the second perforated muffler. The first and second perforated mufflers are fixedly connected, and their outer ends are fixedly connected to their inner ends. After entering the air guide shell and the first perforated muffler, exhaust gas flows through the holes in the first perforated muffler into the air guide shell for initial silencing. Then, it flows through the air guide shell into the second perforated muffler for secondary silencing, and finally through the second perforated muffler into the exhaust hood for final discharge. Through these multiple silencing processes, noise is further reduced.

[0008] Preferably, the air guide shell includes a housing, and an inlet pipe is fixedly connected inside the housing. Flue gas enters the housing through the inlet pipe, and then enters the first perforated silencer through the housing, facilitating initial noise reduction by the first perforated silencer.

[0009] Preferably, the first perforated silencer includes a first perforated hopper, the outer end of which is fixedly connected to the inner wall of the housing, and the inner end of which is fixedly connected to a first perforated cover body. The first perforated cover body is located outside the inlet pipe, and a baffle is fixedly connected inside the first perforated cover body. After the flue gas enters the first perforated cover body through the inlet pipe, it is discharged outward through the holes of the first perforated cover body. After entering the housing, the flue gas passes through the first perforated hopper and is further silenced by the first perforated hopper, thus further reducing noise.

[0010] Preferably, the second perforated silencer includes a second perforated hood body, a second perforated hopper fixedly connected to the outside of the second perforated hood body, the outer end of the second perforated hopper fixedly connected to the inner wall of the housing, and a partition fixedly connected to the inside of the second perforated hopper. After passing through the second perforated hopper, the flue gas enters the second perforated hood body, where it is further noise-reduced by the second perforated hood body and the second perforated hopper.

[0011] Preferably, the exhaust hood includes an isolation cover, the outside of which is fixedly connected to the housing, and an exhaust pipe is fixedly connected inside the isolation cover. Smoke enters the isolation cover through the second perforated cover, is concentrated in the exhaust pipe, and is discharged through the exhaust pipe, facilitating smoke extraction.

[0012] Preferably, the exhaust hood further includes a perforated pipe, which is fixedly connected to the exhaust pipe. The flue gas passes through the perforated pipe into the exhaust pipe and undergoes final silencing through the perforated pipe.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. After the flue gas enters the air guide shell and the first perforated silencer, it is discharged into the air guide shell through the holes of the first perforated silencer for the first silencer, and then flows into the second perforated silencer for the second silencer. It is then discharged into the exhaust hood through the second perforated silencer and discharged outward through the exhaust hood. Through multiple silencers, the noise is further reduced.

[0015] 2. The flue gas enters the housing through the inlet pipe, and then enters the first perforated silencer through the housing, which facilitates the initial silencing by the first perforated silencer.

[0016] 3. After the flue gas enters the first perforated hood through the inlet pipe, it is discharged to the outside through the holes of the first perforated hood. After entering the shell, the flue gas passes through the first perforated hopper and is silenced again through the first perforated hopper, further reducing the noise.

[0017] 4. After the flue gas passes through the second perforated hopper, it enters the second perforated hood body, where noise is further reduced by the second perforated hood body and the second perforated hopper.

[0018] 5. Smoke enters the isolation hood through the second perforated hood, is concentrated in the exhaust pipe through the isolation hood, and is discharged through the exhaust pipe, which facilitates smoke extraction. Attached Figure Description
