Further, the technical solution of the utility model can also be:
Described buckle is to be the card column that three-pawl type distributes, described card column stretches into described ventilating hole, the seam of extremely described card column bottom props up the perforated wall of described ventilating hole, the inwall close contact of the outer wall of described card column and described ventilating hole, and there is slightly outwardly Ka Tai on the top of described card column, the internal surface clamping of the outer wall of described Ka Tai and the described main body that is connected described ventilating hole, thereby fixing described protective hat and described canister.
Described filter element supporting structure is four equally distributed supporting posts.
On described main body, be provided with ring-type splash guard perpendicular to the surface of described main body around described ventilating hole; The outer wall of described splash guard evenly is provided with a plurality of fins; Filter core is stuck in described splash guard, and the fin on the inwall of described protective hat and described splash guard connects and fixes.
One gap is arranged on described splash guard.
The beneficial effects of the utility model are:
(1) avoid water and the grains of sand directly to fall into canister inside, stop up the canister ventilating hole, avoid causing the canister ability to work to descend because of the intrusion of water;
(2) avoid dust that in air, particle is larger to enter canister inside with air-flow, stop up the canister ventilating hole;
(3) avoiding canister protective hat in the car load running process comes off because of vibration.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Of the present utility model a kind of novel carbon tank structure as shown in Fig. 2-5 comprises canister main body 1, and canister main body 1 is provided with a ventilating hole that communicates with ambient air 2, also comprises a protective hat 3, and protective hat covers on the top of ventilating hole; The central part of protective hat is also outstanding is provided with buckle 6, and buckle stretches into ventilating hole, and protective hat is fastening by buckle and ventilating hole clamping, and when having guaranteed that vehicle travels under various operating modes, protective hat can not come off.Along its inwall, filter core 4 is set in protective hat, also is provided with the filter element supporting structure 5 of protrusion in the lid bottom of protective hat, filter element supporting structure is stuck in filter core in space between protective hat and filter element supporting structure.
In this example, filter element supporting structure is four equally distributed supporting posts.
In this example, buckle is to be the card column that three-pawl type distributes, card column stretches into ventilating hole, prop up the perforated wall of ventilating hole to the seam 7 of card column bottom, the inwall close contact of the outer wall of card column and ventilating hole, and there is slightly outwardly card platform 8 on the top of card column, the internal surface clamping of the outer wall of Ka Tai and the main body that is connected ventilating hole, thereby fixed protection cap and canister main body.
In this example, on the canister main body, be provided with ring-type splash guard 9 perpendicular to the upper surface of canister main body around ventilating hole; The outer wall of splash guard evenly is provided with a plurality of fins 10; Filter core is stuck in splash guard, and the inwall of protective hat and the fin on splash guard connect and fix.
Pass through said structure, after ventilating hole on protective hat of the present utility model and canister body is fixed, the seam of buckle bottom has guaranteed that with the cooperation of the canister ventilating hole degree of depth buckle forms firm being connected with ventilating hole with the distance at the top of card column, has avoided protective hat in the car load running process and has come off because of vibration.Filter element supporting structure has been guaranteed to keep function in the long-term using process of filter core, is easy to simultaneously realize large-scale production.Filter core be arranged on the canister splash guard inboard and with the upper surface butt of canister body, cover the screens effect of the seam of buckle bottom due to protective hat, position and the shape of filter core had both been guaranteed, guaranteed that again atmosphere can flow in the gap of protective hat bottom and the formation of canister body, air-flow direction 12 as shown, can intercept like this grains of sand and water and enter the canister main body by protective hat, air that simultaneously again can the filter bag dust, guarantee to suck the turbidity test of the air of canister, guaranteed the venting capability of canister in long-term using process itself.Above-mentioned design greatly reduces the possibility that canister desorption resistance increases, and has also solved the ventilating hole blockage problem that the canister ventilating hole causes because of the grains of sand, water and dust invasion, and has solved the failure of fuel system problem that therefore causes.This structure can also guarantee that the water of the upper surface of canister main body can not soak filter core.
In this example, one gap 11 is arranged on splash guard, it is as the flowing water mouth, only need to keep the downward-sloping very little angle of opening position, just can guarantee that filter core is not soaked in water, be conducive to simultaneously unexpected water of invading in manger board and automatically flow out, avoid causing the canister ability to work to descend because of the intrusion of water, guarantee the operating life of filter core, extended the working life with the canister main body of protective hat.
By using the carbon tank structure after above-mentioned improvement, can effectively avoid stopping up because of canister fuel tank abnormal sound, the distortion fault feedback (CPIP) that causes.Originally the extreme road conditions situation that to stop up namely appear in the 5000km canister of travelling also has great improvement, adopt present technique after failure free time can rise to more than 60,000 kilometers.Of the present utility model simple in structure, cost is low: maintenance scheme is simple and easy to do, only need change protective hat, can make the canister maintenance cost reduce approximately 95%.
Above-mentionedly only the concrete enforcement in the utility model is illustrated; but can not be as unique foundation of protection domain of the present utility model; every equivalence of making according to the design spirit in the utility model changes or modifies, and all should think to fall into protection domain of the present utility model.
