The invention mainly belongs to the technical field of oil tank design and relates to a negative pressure type low-dead-oil anti-bubble aircraft oil tank device. The negative pressure type low-dead-oil anti-bubble aircraft oil tank device comprises an oil tank shell, an oil suction hose arranged inside the oil tank shell, an oil filler and an oil outlet that are arranged on the oil tank shell. The negative pressure type low-dead-oil anti-bubble aircraft oil tank device further comprises a wave-resistant baffle; the wave-resistant baffle consists of at least one wave-resistant baffle; the wave-resistant baffle divides the internal space of the aircraft oil tank device into at least two spaces; every two adjacent spaces communicate with each other through a communication port in the bottom of the corresponding wave-resistant baffle; and the negative pressure type low-dead-oil anti-bubble aircraft oil tank device introduces the oil in the high pressure space into the low pressure oil supply space by means of the pressure difference between the adjacent spaces. The negative pressure type low-dead-oil anti-bubble aircraft oil tank device provided in the present invention sucks the oil to flow towards the low pressure area by means of the pressure difference between different spaces inside the oil tank, and the oil can automatically flow towards the lower side under the gravity action along an internal slope of the aircraft oil tank device.
