For this, Chinese patent notification number is that CN104477292A discloses a kind of anti-rock volatilization prevention leakage motorcycle tank, including casing and case lid, case lid includes cage and cover plate, have in the middle part of cage and the tubular structure of oil filler matched in clearance, the bottom of tubular structure is provided with air inlet, tubular structure be internally provided with oil-gas separating filter element, cover plate is provided with venthole；Also include the oil-choking plate being transversely arranged in casing.This patent by arranging spoiler in casing, when making that oil mass is less in fuel tank, fuel oil rocking in fuel tank greatly can be slowed down because of the barrier effect of spoiler, it is thus possible to avoid fuel oil acutely to rock the problem causing roadability to be deteriorated, also it is avoided that the fuel oil danger of combustion problem because fuel oil severe impact causes.
But, this patent there is problems in that and adopts spoiler that the fuel oil in fuel tank is intercepted in patent, thus when preventing that in fuel tank, oil mass is less, the phenomenon rocked occurs, but, this spoiler can not regulate height, when the distance of oil mass Yu spoiler is relatively larger, and the anti-shake poor effect that spoiler plays；Meanwhile, adopt inside tubular structure by structures such as filter elements, it is achieved the air pressure of fuel tank is equal with atmospheric pressure, it is simple to make the oil in fuel tank flow out smoothly, and avoid oil vapour to run out of in fuel tank, but this complicated structure, and cost is higher.
Utility model content
The purpose of this utility model is to provide the motorcycle tank of balanced type, it is possible to reduces rocking of the fuel oil in fuel tank, meanwhile, adopts simple structure so that air pressure and atmospheric pressure in fuel tank are equal, and does not have oil vapour and run out in fuel tank.
This utility model provides a kind of base case: the motorcycle tank of balanced type, including casing and case lid, casing top is provided with oil filler, air bag it is provided with in casing, casing upper end offers inflation inlet, being provided with in inflation inlet and the boss of inflation inlet concentric, be provided with air-filled pore in boss, inflation inlet is arranged above with lid.
Operation principle and when having the beneficial effect that work, is opened case lid, is added in fuel tank by fuel oil by oil filler.Along with the use of fuel oil, the interior upper end of fuel tank forms negative pressure so that air pressure and atmospheric pressure in fuel tank are unequal, cause that fuel oil cannot flow out smoothly, and for this, prior art adopts and arranges air equalizer opening, but has oil vapour and run out.Different from prior art, this utility model adopts places air bag in fuel tank, and when fuel oil is fewer time, air bag can fill the white space of fuel oil upper end, it is ensured that the air pressure in fuel tank is equal with atmospheric pressure, it is simple to fuel oil flows out smoothly.Meanwhile, the lower end of air bag contacts with fuel oil, it is possible to rocking of fuel oil is played well buffering and iris action, and compared to the spoiler of hard, the elastic space that air bag obstruct fuel oil rocks is bigger, and noise is little, simple in construction, and is easily changed.When fuel oil is more, fuel oil meeting compressing gasbag, and air bag can carry out the change of volume accordingly, using and pouring into without influence on fuel oil, convenient use.Being provided with inflation inlet to be mainly used in air bag is put into casing, by the muzzle of air bag on boss, the entirety of air bag is placed in air-filled pore, so so that air bag is put into casing, and can air bag can be inflated.
Further prioritization scheme one for base case: the sidewall of casing is provided with watch window, so can observe the inflation situation of air bag, it is prevented that airbag aeration too much explosion, increases safety.
Further prioritization scheme two for prioritization scheme one: inflation inlet outer sheath is provided with sealing gasket, it is simple to fuel tank is sealed, it is prevented that the volatilization of oil vapour, contaminated air, waste resource.
Further prioritization scheme three for base case: casing is arranged above with handle, it is simple to casing can be mentioned by people, convenient carrying.
