Abstract
The present invention relates to a kind of integral type multi-frequencies can be changed noise elimination air cleaner, including filter box, dirty air pipe and silencer, the filter box are connected with dirty air pipe, form a closed cavity, the silencer is arranged in closed cavity.The silencer is changeable type silencer.Compared with prior art, the present invention reaches the noise for eliminating different frequency, realizes shared, the low, advantages of simple structure and simple with development cost in different automobile types and different engines by replacing different silencers.
Description
Technical field
The present invention relates to a kind of air cleaners, can be changed noise elimination air-filtering more particularly, to a kind of integral type multi-frequency
Device.
Background technology
Air into engine need to be filtered by air cleaner, in order to reduce making an uproar for engine aspirating system
Sound is respectively to be inserted into two insertion tubes in air cleaner assy air inlet/outlet in the prior art, until the centre bit of upper-lower casing
It sets to reach noise reduction purpose, belongs to reactive muffler.Reactive muffler is that at mutation that sound passes through pipeline section or side connects altogether
The chamber etc. that shakes causes the change of impedance during acoustic propagation and generates the reflection of acoustic energy, interference, outside by silencer to reduce
The acoustic energy of radiation, to reach the silencer of noise elimination purpose.
Currently, with the proposition of vehicle platform concept, the vehicle vehicle boundary of same factory's exploitation is roughly the same, this
The product versatility requirement that sample has led to gas handling system greatly improves, but since engine displacement is different, turbocharging
The configuration of gas is different, leads to the multifarious of the performance of gas handling system.The difference of especially gas handling system acoustical behavior causes
Gas handling system is different, and the development cost of product also improves therewith.
Invention content
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of applied widely, drops
Integral type multi-frequency inexpensive, simple in structure can be changed noise elimination air cleaner.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of variable noise elimination air cleaner of integral type multi-frequency, including filter box, dirty air pipe and silencer, the filter box
It is connected with dirty air pipe, forms a closed cavity, the silencer is arranged in closed cavity.
The silencer is changeable type silencer.
The silencer is equipped with the changeable type acoustic element for being used to form resonant cavity.
The changeable type acoustic element includes Helmholtz's muffler, quarter-wave long tube muffler and porous noise reduction
It is one or more in device.
The filter box and dirty air pipe detachable connection.
The filter box is connect with dirty air pipe by snap, bolt mode or welding manner.
Compared with prior art, the present invention has the following advantages：
(1) present invention integrates dirty air pipe and filter box, and uses replaceable silencer, and it is different to reach elimination
The purpose of the noise of frequency is suitable for different type engine；
(2) it can be shared in gas handling system of the present invention between different platform, achieve the purpose that save development cost；
(3) the configuration of the present invention is simple, it is easy for installation.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the exploded perspective view of the present invention.
Specific implementation mode
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to
Following embodiments.
As Figure 1-Figure 2, a kind of integral type multi-frequency can be changed noise elimination air cleaner, including filter box 1, dirty air pipe 3
With silencer 2, filter box is connected with dirty air pipe, forms a closed cavity, and silencer is arranged in closed cavity.
Silencer 2 is changeable type silencer.Silencer 2 is equipped with the changeable type acoustics member for being used to form resonant cavity
One or more, changeable type in part, including Helmholtz's muffler, quarter-wave long tube muffler and porous muffler
Acoustic element can form the resonant cavity of a variety of noise eliminations, achieve the purpose that noise elimination.
It filters box 1 and uses detachable connection mode, such as snap, bolt mode, welding manner with dirty air pipe 3,
Facilitate the replacement of silencer 2.
Above-mentioned variable noise elimination air cleaner does not become in guarantee shape, can be changed by replacing internal muffler
The acoustic characteristics for becoming gas handling system, the gas handling system reached between various types of engines, different platform share, and saving is opened
Hair expense.
