Abstract
The invention discloses an oil return type oil box which comprises a box body (1), wherein a vaporizer tube (2) is installed in the box body (1), and an output section (2C) of the vaporizer tube (2) protrudes out of the box body (1) and is communicated with a carbon tank (4). The invention is characterized in that an input section (2A) of the vaporizer tube (2) is close to the top end of the box body (1) and is coiled for at least one circle in the horizontal direction; and a middle section (2B) of the vaporizer tube (2) is positioned in the box body (1) and is connected with the input section (2A) and the output section (2C). The oil return type oil box can prevent liquid fuel oil from flowing into the carbon tank, thereby ensuring the adsorption effect of the carbon tank (4).
Description
Technical field
The invention belongs to fuel tank, relate in particular to the oil return type oil box on a kind of fuel combustion vehicle.
Background technology
As shown in Figure 3, the fuel tank of fuel combustion vehicle mostly comprises casing and vapourizer tube at present, the fuel-steam acquisition port of vapourizer tube upper end is positioned at more than the fuel level, the lower end of vapourizer tube passes casing and is connected with the canister input end, the fuel-steam acquisition port up, be used to gather the fuel-steam of casing top gasification, canister adsorbs fuel-steam by vapourizer tube, and the fuel-steam of absorption flowed to driving engine and burn, this prevents that the fuel oil volatilization from causing the waste of fuel oil, saves fuel oil.
If the motor bike canting or when travelling road conditions jolt, the fuel oil in the fuel tank may flow into canister by vapourizer tube, causes and gathers fuel oil in the canister in a large number, influences the adsorption effect of canister.
The shortcoming of prior art is: liquid fuel flows into canister easily, causes and gathers fuel oil in the canister in a large number, influences the adsorption effect of canister, even causes canister to work.
Summary of the invention
The purpose of this invention is to provide a kind of liquid fuel that can prevent and flow into the oil return type oil box of canister.
For achieving the above object, the present invention explains a kind of oil return type oil box, comprise casing, in this casing vapourizer tube is installed, the deferent segment of described vapourizer tube stretches out casing, and communicates with canister, and the mouth of this canister communicates with driving engine, its key is: the top of the close described casing of the input section of described vapourizer tube, and should import section in the horizontal direction around at least one circle; The interlude of described vapourizer tube is positioned at casing, connects described input section and deferent segment.
The fuel-steam acquisition port of described vapourizer tube input section is downward-sloping.
Vapourizer tube input section is positioned at more than the fuel level, this vapourizer tube input section horizontal direction along the fuel tank roof around at least one circle, the fuel-steam acquisition port is downward-sloping, canister is by the fuel-steam of vapourizer tube absorption casing top volatilization, and deliver to driving engine and burn, save fuel oil.
If the fuel oil that splashes enters fuel-steam acquisition port or motor bike canting in setting upright the motor bike process, fuel oil can flow out from the fuel-steam acquisition port of canting, the coiling of one circle even multi-turn vapourizer tube input section, can prevent effectively that liquid fuel from flowing directly into canister, simultaneously, fuel-steam acquisition port in conjunction with downward-sloping is more conducive to liquid fuel and passes back into fuel tank.
Even if there is the fuel oil that has lacked to reside in vapourizer tube, a spot of fuel oil also can volatilize in the input section that has extended fully, and this has just stopped liquid fuel and has flowed into canister, guaranteed the adsorption effect of canister.
The interlude of described vapourizer tube is equipped with check valve.
Check valve can guarantee that the fuel-steam that volatilizees can only unidirectionally enter canister.
Described cabinet wall is welded with at least one evaporating tube support, and this evaporating tube cantilever tip all is fixed with back-up block, and described vapourizer tube point is welded on the described back-up block.
The evaporating tube support is welded on cabinet wall, supports the vapourizer tube of electric welding on its back-up block.
Remarkable result of the present invention is: provide a kind of liquid fuel that can prevent to flow into the oil return type oil box of canister, guaranteed the adsorption effect of canister.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of vapourizer tube;
Fig. 3 is existing Oiltank structure scheme drawing.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
As illustrated in fig. 1 and 2, a kind of oil return type oil box comprises casing 1, in this casing 1 vapourizer tube 2 is installed, vapourizer tube 2 is made up of input section 2A, interlude 2B and deferent segment 2C, and wherein the deferent segment 2C of vapourizer tube 2 stretches out casing 1, and communicates with canister 4;
The input section 2A of described vapourizer tube 2 is near the top of described casing 1, and should input section 2A in the horizontal direction along casing 1 roof around at least one circle;
The interlude 2B of described vapourizer tube 2 is positioned at casing 1, connects described input section 2A and deferent segment 2C.
The fuel-steam acquisition port 5 of described vapourizer tube 2 input section 2A is downward-sloping.
The interlude 2B of described vapourizer tube 2 is equipped with check valve 3.
Described casing 1 inwall is welded with at least one evaporating tube support 6, and these evaporating tube support 6 tops are fixed with back-up block 7, and 2 of described vapourizer tubes are welded on this back-up block 7.
Casing 1 inwall is welded with 2,3 or more evaporating tube supports 6.
Its principle of work is:
Vapourizer tube 2 is welded on the evaporating tube support 6 of casing 1 inwall installation, the input section 2A of vapourizer tube 2 is positioned at more than the fuel level, these vapourizer tube 2 input section 2A horizontal directions are around at least one circle, fuel-steam acquisition port 5 is downward-sloping, canister 4 is by the fuel-steam of vapourizer tube 2 absorption casings 1 top volatilizations, and delivers to driving engine and burn.
If the fuel oil that splashes enters fuel-steam acquisition port 5, or when the motor bike canting, in setting upright the motor bike process, fuel oil can flow out from the fuel-steam acquisition port of canting, even if there is the fuel oil that has lacked to enter vapourizer tube 2, a spot of fuel oil can volatilization fully in vapourizer tube 2 flow process.
