What is claimed is: 1. An adjustable vacuum food storage container, comprising: a base being a mounting tray, having an outer edge, a protruding lip being formed on and protruding up from the outer edge, the base including: a vacuum controller that includes: a motor; an eccentric fitting having two
What is claimed is: 1. An adjustable vacuum food storage container, comprising: a base being a mounting tray, having an outer edge, a protruding lip being formed on and protruding up from the outer edge, the base including: a vacuum controller that includes: a motor; an eccentric fitting having two ends with one end connecting to the motor; a rocker arm connecting to the other end of the eccentric fitting; a vacuum pump mounted on the rocker arm; a protective cover covering the motor, the eccentric fitting, the rocker arm and the vacuum pump, thereby protecting the vacuum pump and the motor, and decreasing noise when the food storage container is operating and circulating air from the vacuum pump to cool the motor; first pipes; a back pressure valve connected to the vacuum pump by one of the first pipes; and first clamping rings mounted on and connecting the first pipes to the vacuum pump and the back pressure valve; a pressure sensor automatically detecting chances in a pressure thereof and actuating the motor to switch the vacuum pump on or off until the pressure returns to a pre-determined value; a filter connecting to the pressure sensor on one side and connecting to the back pressure valve on the other side; second pipes connecting the pressure sensor to the filter and connecting the filter to one of the first pipes from the back pressure valve; and second clamping rings connecting the second pipes to the filter, and connecting the second pipes to the pressure sensor; an external power socket that includes: a magnetic loop; a DC contact hooped by the magnetic loop for avoiding electrostatic; and a rectifier inserted into the DC contact on one side and being connected to an external AC power on the other side; a spare battery set; a power switch; and an integrated circuit board; a U-shaped housing mounted on the base, including: an external shell of U-shape, having a front surface, a rear surface and two ends, a food tray being mounted in the external shell between the two ends and having a front, a rear and two end walls, a gasket groove being formed in top edges of the walls, and a gasket being mounted in the gasket groove; an operation indicator; at least one hinge formed on and protruding from the rear surface of the external shell; and a latch protrusion formed on and protruding from the front surface of the external shell; and a cover mounted pivotally on the U-shaped housing, thereby forming an airtight seal against the gasket, the cover including: at least one pintle mounted through a corresponding hinge to pivotally attach the cover to the U-shaped housing; an exhaust valve mounted through the cover and serving as a manual or automatic vacuum breaker; and a latch mounted on the cover, engaging the U-shaped housing to hold the cover securely against the gasket. 2. The adjustable vacuum food storage container of claim 1, wherein a pressure of an accommodation between the cover and the U-shaped housing is kept at about 35 Kpa. 3. The adjustable vacuum food storage container of claim 1, wherein a suction force of the vacuum pump ranges from 0 to 50 Kpa. 4. The adjustable vacuum food storage container of claim 1, wherein the pressure detected by the pressure sensor ranges from 0 to 60 Kpa (negative pressure). 5. The adjustable vacuum food storage container of claim 1, wherein the spare battery set includes several batteries to supply power independently of the external AC power. 6. The adjustable vacuum food storage container of claim 1, wherein the latch of the cover is a fixed latch or a pivoting latch.
