Abstract
The utility model relates to an air filter of an integrated resonant cavity. The air filter comprises a cavity body and a partition plate which is arranged inside the cavity body and enables the cavity body to be separated into two parts, one part is an air filter cavity body, the other part is a resonant cavity body which is provided with an air flowing pipeline communicated with the air filter cavity body, and a noise elimination pipe is arranged inside the resonant cavity body. Compared with the prior, the air filter has the advantages of being compact, beautiful, good in adjustability, low in cost and the like.
Description
Technical field
The utility model relates to a kind of air-strainer, especially relates to a kind of air-strainer of integrated resonant cavity.
Background technique
Motor car engine produces power by gasoline and air mixed combustion in the course of the work, because the impurity in the air is more, if without filtration, throttle valve on the engine charge pipeline is stopped up, the wearing and tearing that the inside that impurity enters into motor also can inner each friction pair of booster engine.Therefore, air all needs the air-strainer of flowing through before in entering into the firing chamber of motor.Air inflow is generally larger in the course of the work owing to motor car engine, and air-flow can produce larger noise by filter cleaner, and this has influence on the quality of automobile.In order to reduce noise, existing air-strainer is all with resonant cavity, and this resonant cavity is arranged between suction tude and the housing usually.
But, also need to install the resonant cavity of a larger volume in the gas handling system of naturally aspirated engine except the air-strainer of a large volume, it is along the line that this large resonant cavity will be arranged in dirty air conduit or the air-strainer rear end cleaned air pipe of air filtering gas front end.Because two cavity volume are all larger, like this layout of dispersion so that, one, open two molds, cost is higher.Two, arrange not compact attractive in appearance.
The model utility content
The purpose of this utility model is exactly the air-strainer that the integrated resonant cavity that a kind of compactness is attractive in appearance, adjustability good, cost is low is provided 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 air-strainer of integrated resonant cavity, it is characterized in that, comprise cavity and dividing plate, described dividing plate is located in the cavity, to be divided into two-part, a part is the air-strainer cavity, and another part is the resonant cavity cavity, described resonant cavity cavity is provided with the air ventilation pipeline that is communicated with the air-strainer cavity, is provided with hush tube in the described resonant cavity cavity;
The air ventilation pipeline that air flows through in the resonant cavity cavity flows into the air-strainer cavity, and the noise that transmits out from motor is simultaneously eliminated by resonant cavity by hush tube or weakened.
Described hush tube is located at the top of air ventilation pipeline.
Described hush tube is connected with the air ventilation pipeline by plug type.
Compared with prior art, the utlity model has following advantage:
1, compact attractive in appearance: resonant cavity is integrated in air filter housing inside, 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 resonant cavity such as need are adjusted frequency of noise elimination, only need to revise interpolation pipe and get final product, and are convenient low-cost.
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 air-strainer of integrated resonant cavity, comprise cavity and dividing plate, described dividing plate is located in the cavity, will be divided into two-part, a part is air-strainer cavity 2, another part is resonant cavity cavity 1, and described resonant cavity cavity 1 is provided with the air ventilation pipeline 3 that is communicated with air-strainer cavity 2, is provided with hush tube 4 in the described resonant cavity cavity, this hush tube 4 is located at the top of air ventilation pipeline 3, and is connected with air ventilation pipeline 3 by plug type.
The air ventilation pipeline 3 inflow air-strainer cavitys 2 that sky flows through in the resonant cavity cavity 1 filter, and the noise that transmits out from motor is simultaneously eliminated by resonant cavity by hush tube 4 or weakened.
Claims (3)
1. the air-strainer of an integrated resonant cavity, it is characterized in that, comprise cavity and dividing plate, described dividing plate is located in the cavity, be divided into two-part, a part is the air-strainer cavity, and another part is the resonant cavity cavity, described resonant cavity cavity is provided with the air ventilation pipeline that is communicated with the air-strainer cavity, is provided with hush tube in the described resonant cavity cavity.
2. the air-strainer of a kind of integrated resonant cavity according to claim 1 is characterized in that, described hush tube is located at the top of air ventilation pipeline.
