Problems solved by technology

[0002] At present, a relatively large-volume resonant cavity needs to be installed in the air intake system of a naturally aspirated engine, and such a large resonant cavity can generally only eliminate low-frequency noise of a single frequency, and for a large-displacement engine, the mid-high frequency part The noise energy of the air intake system is also very large, so it is necessary to add several noise reduction components in the air intake system to eliminate this part of the medium and high frequency noise. This creates a contradiction with the principle of peripheral layout of the engine that requires a compact and beautiful appearance

Embodiment

[0019] Such as figure 1 As shown, a comprehensive muffler device for an air filter includes a muffler tube body 1, a wavelength tube 2 and a resonant cavity 6, and the muffler tube body 1 is set in the cavity of the air filter, Both the wavelength tube 2 and the resonant cavity 6 are fixed on the muffler tube body 1 , and the muffler tube body 1 is provided with a large muffler hole 3 and several small muffler holes 4 .

[0020] The upper and lower ends of the muffler pipe body 1 are provided with clamping plates 5, through which the clamping plates 5 are clamped with the cavity of the air filter, and the cost of clamping is low and the installation is convenient. The diameter and quantity of the large sound-absorbing hole 3 and the small sound-absorbing hole 4 are adjusted according to the frequency of the corresponding noise. The muffler pipe body 1 is a muffler pipe body made of plastic material.

[0021] The invention is installed in a larger air filter cavity, the sucke...

Embodiment 2

[0023] A comprehensive muffler device for an air filter, comprising a muffler tube body 1, a wavelength tube 2 and a resonant cavity 6, the muffler tube body 1 is set in the cavity of the air filter, and the Both the wavelength tube 2 and the resonant cavity 6 are fixed on the muffler tube body 1 , and the muffler tube body 1 is provided with a large muffler hole 3 and several small muffler holes 4 .

[0024] The muffler pipe body is connected with the air filter cavity by welding. The diameter and quantity of the large sound-absorbing hole 3 and the small sound-absorbing hole 4 are adjusted according to the frequency of the corresponding noise. The muffler pipe body 1 is a muffler pipe body made of plastic material.

[0025] The invention is installed in a larger air filter cavity, the sucked air flows through the cavity and then flows into the engine, and the noise transmitted from the engine is also transmitted to the mouth of the air intake system through the invention, a...

Abstract

The invention relates to a comprehensive type silencer used for an air filter. The comprehensive type silencer comprises a silencer tube body, a wavelength tube and a resonant cavity. The silencer tube body is arranged in a cavity of the air filter, the wavelength tube and the resonant cavity are both formed in the silencer tube body, and a large silencer hole and a plurality of small silencer holes are formed in the silencer tube body. Compared with the prior art, the comprehensive type silencer used for the air filter has the advantages of being compact, attractive, good in adjustability, good in silencing effect, good in flexibility and the like.

Description

technical field [0001] The invention relates to a technology related to an air filter, in particular to a comprehensive muffler device for an air filter. Background technique [0002] At present, a relatively large-volume resonant cavity needs to be installed in the air intake system of a naturally aspirated engine, and such a large resonant cavity can generally only eliminate low-frequency noise of a single frequency, and for a large-displacement engine, the mid-high frequency part The noise energy of the air intake system is also very large, so it is necessary to add several noise reduction components in the air intake system to eliminate this part of the medium and high frequency noise. This conflicts with the principle of peripheral layout of the engine that requires a compact and beautiful appearance. Contents of the invention [0003] The purpose of the present invention is to provide a comprehensive noise reduction device for air cleaners that is compact, beautiful...
