Description
Technical field
This utility model belongs to field of automobile, particularly to a kind of fuel tank device.
Background technology
Fuel tank of vehicle is whole vehicle functions and safety component, and what the quality of fuel tank was related to electromotor does effect
Rate and whether can contaminated air.
During fuel tank refuels, in particular by the vehicle of gasoline, the fuel level meeting in fuel tank
Gradually rise along with the filling of fuel oil.The structure of fuel tank used by conventional gasoline engin, causes fuel tank to fire
Oil filling overfill, causes storing air headspace in fuel tank too small, and fuel oil can the most in fluid form
Entering into canister, canister then cannot filter gasoline vapor, makes canister lose efficacy, and causes oil consumption higher, due to vapour
Oil volatility is higher, and fuel tank filling the most completely can make tank pressure increase, and especially in summer, exists bigger
Potential safety hazard.
At present, the problems referred to above to be avoided, in only judging fuel tank by the experience of fuel filling personnel
The general height of fuel level, thus substantially ensure the headspace in fuel tank, owing to using artificial judgment,
Error in judgement can be there is, and understand waste of manpower resource, increase human cost.
Utility model content
[solving the technical problem that]
The purpose of this utility model is to provide a kind of fuel tank device, to solve cannot protecting of current fuel tank
The problem of the headspace in card fuel tank.
[technical scheme]
This utility model is achieved through the following technical solutions.
This utility model relates to a kind of fuel tank device, including fuel tank body, oil fuel tube, breather peace
Weighing apparatus hard tube, described fuel tank body is provided with oiler, blow vent, one end of described breather and fuel oil
The blow vent of case body connects, and the other end of described breather is connected with the oil filler of oil fuel tube one end, described
The other end of oil fuel tube is connected with the oiler of fuel tank body, and one end of described balance hard tube is with blow vent even
Connecing, the other end of described balance hard tube stretches into fuel tank body interior.
As one preferred embodiment, what described balance hard tube stretched within fuel tank is a length of
20～30mm.
As another preferred embodiment, described fuel tank body uses HDPE high density polyethylene (HDPE) to mould
Material.
As another preferred embodiment, also include the canister being connected with fuel tank body.
[beneficial effect]
The technical scheme that the utility model proposes has the advantages that
This utility model is by arranging balance hard tube between fuel tank body and breather, it is possible to ensure fuel oil
When case refuels, the air in fuel tank is derived to oil filler along with breather, and, when in fuel tank
The filling of fuel level when highly exceeding the lower surface of balance hard tube, the air in fuel tank just cannot discharge,
Now oil gun will automatically recognize fuel tank fill it up with when refueling, and oil gun stops refueling so that pre-in fuel tank
Stay portion of air, be possible not only to prevent fuel tank filling overfill from causing security incident, but also be possible to prevent combustion
Fluid body enters in canister, improves the service life of canister, prevents the pollution of the environment, and improves fuel oil warp
Ji property.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below will be to this utility model
Detailed description of the invention carry out clear, complete description.
The structural principle schematic diagram of the fuel tank device that Fig. 1 provides for this utility model embodiment one.Such as Fig. 1
Shown in, this fuel tank device includes fuel tank body 1, oil fuel tube 2, breather 3, balance hard tube 4, carbon
Tank 5, motor carbon tank solenoid valve interface 6.Canister 5 respectively with fuel tank body 1, motor carbon tank electromagnetism
Valve interface 6 connects.On fuel tank body, 1 is provided with oiler 11, blow vent 12.
One end of breather 3 is connected with the blow vent 12 of fuel tank body 1, the other end of breather 3 and note
The oil filler 21 of oil pipe 2 one end connects, the other end of oil fuel tube 2 and the oiler 11 of fuel tank body 1
Connecting, one end of balance hard tube 4 is connected with blow vent 12, and the other end of balance hard tube 4 stretches into fuel tank originally
Body 1 is internal.In the present embodiment, balance hard tube 4 stretches into a length of 25mm within fuel tank body 1, needs
Illustrating, the length that balance hard tube 4 stretches within fuel tank body 1 is joined with sectional area according to volume of fuel tank
Number is configured, and needs to ensure the height that the height of the lower surface of balance hard tube 4 is not less than oiler 11.Logical
Cross and balance hard tube 4 is set between fuel tank body 1 and breather 3, it is possible to ensure when fuel tank refuels, will
Air in fuel tank body 1 is derived to oil filler 21 along with breather 3, and, when fuel tank body
When the filling of the fuel level in 1 highly exceedes the lower surface of balance hard tube 4, the air in fuel tank body 1
Just cannot discharge, now oil gun will automatically recognize fuel tank fill it up with when refueling, and oil gun stops refueling
So that reserved portion of air in fuel tank body 1.
In the present embodiment, fuel tank body 1 uses HDPE high-density polyethylene plastics, has preferably peace
Quan Xing, higher corrosion resistance and longer service life.
As can be seen from the above embodiments, this utility model embodiment by fuel tank body and breather it
Between balance hard tube is set, it is possible to ensure fuel tank refuel time, by the air in fuel tank along with breather derive
To oil filler, and, when the filling of the fuel level in fuel tank highly exceedes the lower surface of balance hard tube
Time, the air in fuel tank just cannot discharge, and now oil gun will recognize fuel tank automatically when refueling
Filling it up with, oil gun stops refueling so that reserving portion of air in fuel tank, to prevent fuel liquid to be sucked into carbon
In tank, improve the service life of canister, prevent the pollution of the environment, improve fuel economy.
It is to be appreciated that embodiments described above is a part of embodiment of the present utility model rather than all
Embodiment, is not to restriction of the present utility model.Based on embodiment of the present utility model, this area is common
The every other embodiment that technical staff is obtained under not paying creative work premise, broadly falls into this practicality
Novel protection domain.
