Cancel clip and sebific duct, fast plug and nylon tube than conventional coupling arrangement, can effectively reduce system cost, improves assembly effect
Rate.
2. the utility model has the effect that the setting for hole site of ventilating, when, ensure that air enters canister filtering
While device, it can prevent the dust in air from being entered in carbon canister filter by venthole, because dust is usually from upper
Toward whereabouts；Second is that if the dust assembled in carbon canister filter is more or vehicle during traveling carbon canister filter by
It shakes, the dust in carbon canister filter can be dropped out from aperture.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments：
Fig. 1 is the attachment structure schematic diagram of the utility model carbon canister filter and logical air pipe.
Fig. 2 is the front view that the utility model carbon canister filter connect one end with logical air pipe.
Fig. 3 is sectional view when the utility model carbon canister filter is assembled together with logical air pipe.
Label in above-mentioned figure is respectively：1. carbon canister filter；2. logical air pipe；3. buckle；31. holder；32. elastic card
Piece；4. positive stop lug boss；5. venthole.
Specific implementation mode
In the present invention, in the absence of explanation to the contrary, the noun of locality used such as " top, bottom, left and right " is usual
Refer to top, bottom shown in refer to the attached drawing, left and right；" inside and outside " refers to the inside and outside of the profile relative to each component itself.
As shown in Figure 1, Figure 2, Figure 3 shows, the connection structure of a kind of carbon canister filter and logical air pipe, including carbon canister filter 1
It is connect with carbon canister filter 1 with one end of logical air pipe 2, logical air pipe 2, the other end of logical air pipe 2 is connect with canister, canister
Filter 1 is equipped with buckle 3, and number >=1 of the buckle 3 leads to air pipe 2 and is equipped with positive stop lug boss 4.Pass through buckle 3 and limit
Carbon canister filter 1 and logical air pipe 2 are fixed boss 4 and axial limiting, can realize that automotive fuel oil system canister filters
Device 1 is reliably connect with logical air pipe 2, while cancelling clip and sebific duct, fast plug and nylon tube compared to conventional coupling arrangement,
System cost can effectively be reduced and improve efficiency of assembling.
It is the relatively soft filtering dust sponge of quality inside carbon canister filter 1.In carbon canister filter 1 be equipped with for it is big
The logical venthole 5 of gas phase, location status when carbon canister filter 1 of being subject to works normally, the venthole 5 setting are filtered in canister
Device 1 is on the end face of the earth, i.e., the exposed opening in an atmosphere of the venthole 5 is towards greatly.Such setting, when, it protects
While card air enters carbon canister filter 1, it can prevent the dust in air from entering carbon canister filter 1 by venthole 5
