The utility model relates to an air filter for a passenger car. The air filter comprises a shell and a filter core, wherein the shell consists of a lower shell and an upper cover, an air inlet pipe is arranged on the lower shell, an air outlet pipe is arranged on the upper cover, the lower shell and the upper cover are fixedly connected to form an air inlet cavity and an air outlet cavity which are communicated with each other by the filter core, the air inlet cavity consists of an air inlet cavity I, an air inlet cavity II and an air inlet cavity III which are formed by separation through shell plugboards, and are positioned at outer sides of two ends of the filter core and below the filter core, the air inlet cavity I is a cavity at the outer side of the filter core close to the air inlet pipe, the air inlet cavity III is a cavity at the outer side of the other end of the filter core, and the air inlet cavity III is a cavity below the filter core; the air inlet pipe extends into the interior of the lower shell, and the tail end of the air inlet pipe is below the filter core; the air outlet pipe extends into the interior of the upper cover, and the tail end of the air outlet pipe is above the filter core; and a sealing adhesive tape is further arranged between the lower shell and the upper cover. The air filter has the advantages of being low in air inlet resistance, lower in noise, good in sealing property and damping property, and the like.
Description
Technical field
The utility model relates to a kind of air-strainer, and particularly a kind of passenger car is used air-strainer.
Background technique
The effect of air-strainer is the various impurity in the filtered air, gets into motor with the air that guarantees cleaning, make burning more fully with make air system unobstructed.The empty filter of high-quality is the vitals that guarantees the normal operation of motor.The major requirement of air-strainer is that filtering efficiency is high, flow resistance is low, can uses and service free continuously the long period.At present, the employed air-strainer of passenger car normally is made up of lower shell body, filter core, loam cake; The shape of cross section of its filter core is identical with the shape of cross section of lower shell body; It is admission space that the lower shell body space of filter core below is promptly only arranged, and admission space is less, also has suction tude and steam outlet pipe not to insert and extends to enclosure interior; The air-strainer of this structure exists intake resistance excessive, the shortcoming that acoustic attenuation performance is bad.
Summary of the invention
The technical problem that the utility model will solve is: provide a kind of intake resistance low, reduce noise, sealing and the good passenger car of acoustic attenuation performance and use air-strainer, to solve the problem that exists in the above-mentioned existing technology.
The technological scheme that solves the problems of the technologies described above is: a kind of passenger car is used air-strainer; Comprise shell and filter core; Shell is made up of lower shell body and loam cake, and described lower shell body is provided with suction tude, and loam cake is provided with steam outlet pipe; Lower shell body and loam cake have been fixedly connected to form air-inlet cavity and outlet chamber; Be communicated with through filter core between air-inlet cavity and the outlet chamber, described air-inlet cavity comprises by the housing plate isolates air inlet cavity I, air inlet cavity III and three cavitys of air inlet cavity II that form, be positioned at the outside, filter core two ends and below, and air inlet cavity I is to be positioned at the cavity of filter core near the suction tude one end outside; Air inlet cavity III is the cavity that is positioned at the filter core the other end outside, and air inlet cavity II is the cavity that is positioned at the filter core below.
Described suction tude extends into lower shell body inside, and the suction tude tail end is positioned at the filter core below, and described steam outlet pipe extends into loam cake inside, and the steam outlet pipe tail end is positioned at the filter core top.
Also be provided with sealing joint strip between described lower shell body and the loam cake.
Because adopt said structure, a kind of passenger car of the utility model is used air-strainer, has following beneficial effect:
1, intake resistance is lower: the air-inlet cavity of the utility model is isolated air inlet cavity I, air inlet cavity III and three cavitys of air inlet cavity II of forming, being positioned at the outside, filter core two ends and below by the housing plate and is constituted; Promptly increased the volume of air-inlet cavity; Also have suction tude to adopt and be inserted into the inner structure of lower shell body; Improved air-flow, made intake resistance lower.
2, the steam outlet pipe of the utility model adopts and is inserted into the inner structure of loam cake, has reduced noise.
3, the utility model is provided with sealing joint strip between lower shell body and loam cake, thereby has promoted the sealing and the acoustic attenuation performance of air-strainer.
4, the structural type of the utility model realizes on technology more easily.
Below, in conjunction with accompanying drawing and embodiment a kind of passenger car of the utility model technical characteristics with air-strainer is further described.
