The first side plate, the second side plate, third side plate and the 4th side plate being sequentially connected end to end in turn, air inlet are located on the first side plate close to the
One end of four side plates, gas outlet are located at one end on the second side plate close to third side plate, and the bottom of the first side plate is lower than third side
The bottom of plate.
Preferably, multiple locating slots and multiple limiting stands are provided on the lower surface of cover board, locating slot and skimming baffle hang down
Straight corresponding, the quantity of locating slot is equal with skimming baffle quantity.
Preferably, spoiler is additionally provided on the lower surface of cover board, tray interior is additionally provided with escape pipe, escape pipe connection
Gas outlet, spoiler keeps off the front end in the entrance of escape pipe, for increasing the flow path of fuel-steam.
The utility model has the following beneficial effects: fuel-steam first passes through liquid trap before by canister, fuel oil steams
Vapour collides after air inlet enters liquid trap with skimming baffle, the fuel droplets of bulky grain is separated, by separation
Fuel-steam is discharged into canister by gas outlet, mitigates the burden of canister, reduces the pollutant emission of refueling process, the combustion in liquid trap
Oil is back in fuel tank due to gravity from air inlet.
