Described vacuum air valve is by circular seal base, umbrella ducon and umbrella lifter form, circular seal base is soft yielding silica gel, circular seal base center is provided with the locating groove of opening upwards, circular seal base end face is sealing plane, sealing plane be positioned at open-work directly over, ducon center is provided with mounting hole, ducon bottom is provided with the cylindrical kerve with ventilative groove interference assembling, directly the cylindrical kerve of ducon is aimed at ventilative groove and down force fit device make it complete interference assembling, this mounting hole and kerve conducting, this lifter center is provided with air extractor vent, lifter top is for compressing the spacing plane of mounting hole, lifter bottom is cylindrical air channel, and end surfaces is provided with the snap ring fastening with mounting hole interference in air channel, snap ring below has a pair of gas port, air channel bottom is provided with for blocking the card tooth of circular seal base, lifter interference from top to bottom penetrates in mounting hole, snap ring is stuck in mounting hole below, make in the trip segment of lifter above snap ring up and down, circular seal base penetrates in kerve from the bottom up, card tooth is clamped in locating groove, when making lifter oscilaltion activity, drive circular seal base up and down.
Vacuum: first lifter is depressed, then use supporting evacuator to be connected with the air extractor vent of vacuum air valve, in the working process of evacuator, make the air in keeping box body discharge toward open-work, through ventilative groove, flow to vacuum air valve, from the peripheral gap of circular seal base, flow in kerve again, finally from air channel gas port with it, flow out to air extractor vent and extracted out by evacuator.In the process vacuumizing, because the air in keeping box body is constantly drawn out of, pressure in keeping box body is constantly reduced, form draught head with the air pressure outside keeping box body, make circular seal base produce deformation under the effect of bar pressure, the circular seal base that has vacuumized rear generation deformation is close to the surface of open-work under the effect of bar pressure, makes formation vacuum state in keeping box body.
Enter air event: directly lifter is mentioned, in the time of lifter rising activity, drive circular seal base upwards movable, under the effect of external force, circular seal base and the open-work of being close to open-work are originally departed from, under the effect of bar pressure, air enters in keeping box body from open-work.
As preferably, this fresh-keeping box cover bottom edge is provided with seal groove, and in seal groove, seal ring is installed.
As preferably, sealing circle consists of silica gel material, and is provided with the inclined plane sealing structure for two way seal at seal ring edge.The inclined plane sealing structure of setting up, can reach the effect of two way seal.
As preferably, at fresh-keeping box cover medial surface, also have additional for observing the vacuum data sheet of degree of vacuum, can observe at any time the vacuum value in keeping box body by vacuum data sheet.
As preferably, lifter top is provided with the circular handle of being convenient to promote venting, while vacuumizing, toward pressing down circular handle, in the time of need to uncapping, with hand, circular handle is directly mentioned, and operating process is quick simply again.
As preferably, this keeping box body is rectangular structure, and at the opening edge of keeping box body along being provided with the sealing inclined-plane for two way seal.
As preferably, this sealing plane surface is provided with protruding seal mouth ring, makes sealing effectiveness better.
That the air extractor vent of this vacuum air valve can be common to air exhaust nozzle and bleed without hand-operating vacuum-pump and the electric vacuum pump of air exhaust nozzle.This fresh-keeping box cover can be used in conjunction with the common crisper that other opening sizes approach, and reaches the effect of vacuum freshness retaining.
The beneficial effect that the utility model produces is: Novel vacuum fresh-keeping box, simple to operation, during use, by vacuum pumping pump, extract the air in keeping box body, make one-tenth vacuum state in box body, after exhausting vacuum, without any need for operation, can simply lock air, between circular seal base and open-work, can not produce gap, effectively prevent that outside air from entering in vacuum freshness retaining box body, thereby guaranteed the fresh-keeping effect of vacuum crisper, slow down the oxidizing process of food, reach the object that extends fresh keeping time, the vacuum crisper that is convenient for people to use carries out fresh-keeping to food or other article.
