Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to an automotive muffler. Background Technology

[0002] A car muffler (also known as a silencer or exhaust pipe muffler) is an important component of a car's exhaust system. It is mainly used to reduce the noise of engine exhaust and optimize exhaust emissions. Existing automotive mufflers have the following drawbacks in practical use: When a car engine is cold-started or when combustion is incomplete, some fuel may enter the muffler in liquid form with the exhaust gas and gradually deposit as oil stains. However, existing car mufflers are not easy to disassemble to clean the residual oil stains inside. After a period of use, the muffler holes become clogged with oil stains, and the oil stains adhere to the inner wall of the muffler, affecting the noise reduction of exhaust gas generated by the car engine.

[0018] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0019] In order to solve the problems existing in the background art, this application proposes the following technical solution: a car muffler.

[0020] The specific technical solution includes a first half-cylinder 1 and a second half-cylinder 2. Assembly components 3 are respectively provided at the top and bottom of both half-cylinder 1 and second half-cylinder 2. Each assembly component 3 includes an assembly box 301, an assembly block 302, and a sealing gasket 312. The assembly box 301 is fixedly mounted on the outer wall of the first half-cylinder 1, and the assembly block 302 is fixedly mounted on the outer wall of the second half-cylinder 2. A moving block 303 is slidably connected inside the assembly box 301, and an insert block 304 is provided on the outer wall of the moving block 303, which is inserted into the interior of the assembly block 302. A toothed plate 305 is provided on the outer wall of the moving block 303. A rotating cylinder 306 is rotatably connected inside the assembly block 302, and a toothed ring 307 is provided on the outer wall of the rotating cylinder 306. The gear ring 307 meshes with the gear plate 305. One end of the rotating cylinder 306 is provided with a rotating wheel 308 located outside the assembly box 301. The rotating wheel 308 is slidably connected to the insert rod 309, which is inserted into the outer wall of the assembly box 301. One end of the insert rod 309 is provided with a pull rod 310 extending to the outside of the rotating wheel 308. The rotating wheel 308 is provided with a spring 311 connected to the insert rod 309. The sealing gasket 312 is provided on the outer wall of the first half cylinder 1, which facilitates the disassembly of the first half cylinder 1 and the second half cylinder 2 to clean the oil stains inside the first half cylinder 1 and the second half cylinder 2. This can prevent oil stains from clogging the silencer hole 13 or adhering to the first half cylinder 1 and the second half cylinder 2, thus avoiding the problem of noise reduction during exhaust gas emission.

[0021] In specific implementations, such as Figure 1 , 2 and Figure 4 As shown, a purification component 4 is provided at one end of the half-cylinder 1. The purification component 4 includes a filter tube 401, a circular frame 402 and a protrusion 405. The filter tube 401 is fixedly installed at one end of the half-cylinder 1. The purification component 4 is used to filter particulate matter in the exhaust gas generated by the combustion of automobile engines and to adsorb harmful substances.

[0022] Furthermore, the circular frame 402 is inserted into the inside of the filter tube 401, and the inside of the circular frame 402 is respectively provided with a fine filter screen 403 and an activated carbon component 404. The protrusion 405 is fixedly installed on the outer wall of the top of the circular frame 402. The protrusion 405 facilitates the removal of the circular frame 402 from the inside of the filter tube 401 to clean or replace the fine filter screen 403 and the activated carbon component 404.

[0023] Furthermore, the top thread of the protrusion 405 is threaded through a fixing screw 406, and the bottom thread of the fixing screw 406 is inserted into the outer wall of the top of the round frame 402. By threading the fixing screw 406 out, the protrusion 405 and the round frame 402 can be de-fixed, making it easier to clean or replace the fine filter screen 403 and the activated carbon part 404.

[0024] In specific implementations, such as Figure 2As shown, both the outer walls of half-cylinder 1 and half-cylinder 2 are provided with sound-absorbing sleeves 5, and the inside of the sound-absorbing sleeves 5 is provided with cavities 6. The inside of the cavities 6 is provided with sound-absorbing cotton 7, which can insulate noise and make the sound absorption effect better.

[0025] Furthermore, several baffles 8 are fixedly installed on the inner wall of half-cylinder 1, and several sound-absorbing cavities 9 are formed between the several baffles 8, half-cylinder 1 and half-cylinder 2.

[0026] Furthermore, the interior of several baffles 8 is respectively provided with an inlet pipe 10, a silencer pipe one 11, and a silencer pipe two 12, and the outer walls of the inlet pipe 10, silencer pipe one 11, and silencer pipe two 12 are all provided with silencer holes 13. The outer wall of the filter pipe 401 is provided with an outlet pipe 14. The silencer cavity 9, silencer pipe one 11, silencer pipe two 12, and silencer holes 13 can deflect noise, reflect, cancel, or absorb noise sound waves, thereby reducing exhaust noise.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: In use, the exhaust gas generated by the combustion of the car engine enters the half-cylinder 1 and half-cylinder 2 through the inlet pipe 10. After passing through the muffler pipe 11, muffler pipe 2 12, muffler hole 13 and multiple muffler cavities 9, the noise of the exhaust gas can be deflected, reflected, canceled or absorbed, thereby reducing exhaust noise. Sound insulation cotton 7 is installed on the outside of the half-cylinder 1 and half-cylinder 2 to further insulate the noise, making the noise reduction effect even better. After the noise reduction, the exhaust gas is filtered and purified by the fine filter 403 and activated carbon component 404 of the purification component 4 and then discharged through the outlet pipe 14. The fine filter 403 can filter particulate matter in the exhaust gas generated by the combustion of the car engine, and the activated carbon component 404 can remove harmful substances in the exhaust gas generated by the combustion of the car engine. The adsorption filtration system can purify the exhaust gas produced by the combustion of the car engine passing through the muffler, making it more environmentally friendly. Pulling the lever 310 causes the insert rod 309 to move out of the outer wall of the assembly box 301. Rotating the wheel 308 causes the rotating drum 306 and the gear ring 307 to rotate and mesh with the gear plate 305. This allows the gear plate 305 to move the moving block 303 and the insert block 304, allowing the insert block 304 to move out of the assembly block 302. Pulling the half-cylinder 1 and half-cylinder 2 in the opposite direction can separate the half-cylinder 1 and half-cylinder 2, making it easier to clean the oil stains remaining inside the half-cylinder 1 and half-cylinder 2. This prevents the oil stains from clogging the muffler hole 13 and from affecting the noise reduction during exhaust gas emission.
