The utility model discloses a double -cabin back -suction cosmetic pump and cosmetic container, under the liquid outlet state, press the interface under the action of external force, make the volume of back -suction cabin and power cabin be compressed to make the cosmetic in power cabin enter back -suction cabin through power channel, then enter liquid outlet channel through liquid outlet valve, under the reset state, under the action of reset device, make the volume of back -suction cabin be expanded to make the cosmetic in liquid outlet channel back -suction to back -suction cabin, and make the volume of power cabin be expanded to make the cosmetic in external cosmetic jar enter power cabin through liquid inlet valve. Double -cabin back -suction cosmetic pump can pump out the cosmetic in cosmetic jar under the action of pressing device, and can back -suction the cosmetic remaining in pressing device into double -cabin back -suction cosmetic pump. The cosmetic pump itself is used as buffer zone between cosmetic jar and liquid outlet pipeline, and the contaminated cosmetic is enclosed in buffer zone, that is, in back -suction cabin, thereby avoiding expanding pollution.
