Abstract
The utility model relates to a comprehensive muffling device for an air filter. The comprehensive muffling device for the air filter comprises a muffling pipe body, a wavelength pipe, and a resonance cavity. The muffling pipe body is arranged in an air filter cavity body. The wavelength pipe and the resonance cavity are fixed on the muffling pipe body. The muffling pipe body is provided with a big muffling hole and a plurality of small muffling holes. Compared with the prior art, the comprehensive muffling device for the air filter has the advantages of being compact, elegant, good in adjustability, muffling effect and flexibility and the like.
Description
Technical field
The utility model relates to a kind of air-strainer correlation technique, especially relates to a kind of integrated type silencer for air-strainer.
Background technique
At present, in the gas handling system of naturally aspirated engine, need to install the resonant cavity of a larger volume, the low-frequency noise of a single-frequency and so large resonant cavity generally can only disappear, and the motor for large discharge capacity, the noise energy of medium-high frequency part is also very large, so just need in gas handling system, increase in addition several silencer elements and go to eliminate this part high-frequency noises, these silencer elements can take greatly space, and can be in the pipeline of gas handling system layout along the line, so just the periphery principle of motor attractive in appearance has produced contradiction with requiring compactness.
The model utility content
The purpose of this utility model is exactly to provide the integrated type silencer that is used for air-strainer that a kind of compactness is attractive in appearance, adjustability good, soundproof effect is good, flexibility is good for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of integrated type silencer for air-strainer, it is characterized in that, comprise hush tube body, wavelength pipe resonant cavity, described hush tube body is located in the air-strainer cavity, described wavelength pipe resonant cavity all is fixed on the hush tube body, and described hush tube body is provided with a large bloop and several little bloops.
Described hush tube body is provided with card adapter plate in two ends up and down, by this card adapter plate and the clamping of air-strainer cavity.
Described hush tube body is connected with the air-strainer cavity by welding manner.
Described large bloop diameter and little bloop diameter and quantity are all adjusted according to the frequency of corresponding noise.
Described large bloop diameter is 1/4～1/2 hush tube body caliber.
Described little bloop diameter is 1～5mm.
The hush tube body that described hush tube body is plastic materials.
Compared with prior art, the utlity model has following advantage:
1, compact attractive in appearance: all silencer elements are integrated in an inside cavity, need not occupy other space along the line by the zero scattered pipeline that is arranged in gas handling system loosely;
2, adjustability is good: this pipe such as need change in design, and the mould that only needs to revise this pipe gets final product, and is convenient low-cost;
3, soundproof effect is good, flexibility is good: muffling unit is integrated in one above the pipe, make it produce a comprehensive erasure effect, and a plurality of muffling units on the hush tube can be adjusted its number and dimensional parameters according to the frequency of corresponding noise.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of integrated type silencer for air-strainer, comprise hush tube body 1, wavelength pipe 2 resonant cavity 6, described hush tube body 1 is located in the air-strainer cavity, described wavelength pipe 2 resonant cavity 6 all are fixed on hush tube body 1, and described hush tube body 1 is provided with a large bloop 3 and several little bloops 4.
Described hush tube body is provided with card adapter plate 5 in two ends about in the of 1, by this card adapter plate 5 and the clamping of air-strainer cavity, adopts lower and convenient installation of clamping cost.Described large bloop 3 diameters and little bloop 4 diameters and quantity are all adjusted according to the frequency of corresponding noise.Described hush tube body 1 is the hush tube body of plastic materials.
The utility model is installed in the larger air-strainer cavity, the air that is inhaled into runs through it and flows through inflow engine behind the cavity, the noise that transmits out from motor simultaneously also is delivered to the gas handling system oral area by the utility model, noise when the utility model greatly frequency with weakened or cancellation.
