Description
Technical field
The utility model relates to a kind of vehicle fuel adsorption system.In particular to a kind of automobile canister structure.
Background technique
Vehicle fuel vapor sorption desorption apparatus, is commonly called as canister, is the core component in vehicle fuel oil evaporation adsorption system, is generally contained between petrol tank and motor.Because gasoline is a kind of volatile liquid, fuel tank is often full of steam at normal temperatures, and the effect of vehicle fuel oil evaporation adsorption system is introduced by the steam of fuel tank burn and prevent from evaporateing in air.Its working principle is because active carbon has adsorption function, when automobilism or flame-out time, the gasoline vapour of fuel tank is entered in activated carbon canister by pipeline and is tightly held by activated carbon.After engine misses, gasoline vapour and fresh air are in in-tank mixing and be stored in activated carbon canister, when after engine start, the electromagnetic valve being contained in the fuel evaporation purification plant between activated carbon canister and intake manifold is opened, and the gasoline vapour in activated carbon canister is inhaled into intake manifold and participates in burning.
Existing a kind of carbon tank structure, comprises tank body, and one end, tank body top is set side by side with the adsorption tube for being connected with fuel tank and the desorption pipe for being connected with motor, and the tank body top the other end is also provided with ventilating hole.A kind of canister such as disclosed in China's number of patent application 201120012884.4, namely belongs to this structural type.
After the canister installation of this structure, when motor does not work, gasoline vapour to enter in tank body and the active carbon be adsorbed in tank body from adsorption tube, when after engine start, after the electromagnetic valve at engine intake manifold place is opened, under suction, the gasoline vapour in tank body is inhaled into intake manifold and participates in burning.Wherein ventilating hole is communicated with air said process can be completed smoothly.
In this existing carbon tank structure, because ventilating hole is upwards arranged, easy accumulation dust or enter muddy water, and then produce blocking and destroy adsorption effect of activated carbon in water, poor to active carbon protected effect, canister is shorter for working life.In addition, this existing carbon tank structure, general employing anchor ear is installed fixing, and cost is higher and fixed effect is poor.
Model utility content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of structure simple, good to active carbon protected effect, the automobile canister structure of long service life, and improves its fixing reliability further.
In order to solve the problems of the technologies described above, the utility model have employed following technological scheme:
A kind of automobile canister structure, comprise overall rectangular block structured tank body, the one end at tank body top is set side by side with the adsorption tube for being connected with fuel tank and the desorption pipe for being connected with motor, the tank body top the other end is also provided with ventilating hole, it is characterized in that, described ventilating hole is fixedly connected with a logical air pipe, after described logical air pipe is bending, entrance is arranged downwards.
In the utility model, ventilating hole is fixedly connected with a logical air pipe, after logical air pipe is bending, entrance is arranged downwards.Like this, ventilating hole ventilatory function can be ensured, dust or muddy water etc. can be avoided to enter into canister inside from ventilating hole simultaneously, good to active carbon protected effect, canister long service life.
As optimization, on described tank body inner surface, outwardly convex has extended to form a pair clamp, described logical air pipe be flexible pipe and toward tank body inner surface direction bending downwards after clamping enter clamp and fix.
After such optimization, logical air pipe adopts flexible pipe escapable cost, and logical air pipe bends toward the direction of tank body inner surface, is spaced between tank body and vehicle frame, foreign matter can be avoided better to enter tank body by logical air pipe.Logical air pipe is fixed by clamp simultaneously, and logical air pipe can be avoided to rock, and causes wearing and tearing or sends abnormal sound.
As optimization, described canister inner surface is also provided with mounting structure, mounting structure comprises a mounting plate, mounting plate is arranged on canister inner surface by a mounting bracket interval, mounting plate top is provided with the top connection bump horizontally outward extended, mounting plate side has the side connection bump laterally extended, and described top connection bump and sidepiece connection bump is provided with bolt connecting hole, offers spliced eye in the middle part of described mounting plate.
Like this, during installation, spacing in the spliced eye that the grafting block on vehicle frame can be leaned on to be inserted on mounting plate, then by the bolt connecting hole in the top connection bump of bolt connection plate and sidepiece connection bump and vehicle frame corresponding position, realize three-dimensional fixing from two different directions.Structure is simple, and drastically increases fixed effect.
As optimization, the connection mouth position of described ventilating hole and adsorption tube and desorption pipe is arranged point-blank, and the connection mouth position of adsorption tube is between ventilating hole and the connection mouth position of desorption pipe.Like this, adsorption and desorption effect can be ensured better.
In sum, it is simple that the utility model has structure, good to active carbon protected effect, and the fixed structure of long service life is simple, the quick and high reliability of convenient fixing.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
As one preferably mode of execution during concrete enforcement: as Figure 1-Figure 2, a kind of automobile canister structure, comprise overall rectangular block structured tank body 1, the one end at tank body 1 top is set side by side with the adsorption tube 2 for being connected with fuel tank and the desorption pipe 3 for being connected with motor, the tank body 1 top the other end is also provided with ventilating hole, described ventilating hole is fixedly connected with a logical air pipe 4, after described logical air pipe 4 is bending, entrance is arranged downwards.
Wherein, on described tank body 1 inner surface, outwardly convex has extended to form a pair clamp 5, described logical air pipe be flexible pipe and 4 toward tank body inner surface direction bending downwards after clamping enter clamp 5 and fix.
Logical like this air pipe adopts flexible pipe escapable cost, and logical air pipe bends toward the direction of tank body inner surface, is spaced between tank body and vehicle frame, foreign matter can be avoided better to enter tank body by logical air pipe.Logical air pipe is fixed by clamp simultaneously, and logical air pipe can be avoided to rock, and causes wearing and tearing or sends abnormal sound.
