According to the present invention, no matter teas still is other food, under its vacuum state, can obtain keeping long-term effectively.But according to the article difference of keeping, shape, the specification of lid (1) and container (2) can be correspondingly different, and this also is natural.
Installation and using method according to vacuum container cover of the present invention (1) will be described below.
At first, the article of required keeping are put into container (2); Then, vacuum being covered (1) covers on container (2).The upper limb of bottom recesses (37) and container (2) of the body (3) of lid (1) is plugged separably.
Under initial coupled condition, sliding panel (5) has dropped to the bottom in the body (3).
That is, on the locked projection of stop (52) (36) of the neighboring of sliding panel (5) in body (3).
Under this state, if want to extract out the air of having packed in the container (2) of article, when making container (2) vacuum, at first, the projection (36) of the stop of sliding panel (5) (52) from body (3) unlocked, sliding panel (5) is upwards slided.Then, begin to push sliding panel (5), to carry out vacuum operation.
That is, the stop (52) of sliding panel (5) unlocks from the projection (36) of body (3).Sliding panel (5) direction toward head (4) under the restoring force effect of spring (8) is upwards slided.This sliding panel (5) compresses the space (A) of bleeding.The air in the compressed space of bleeding (A) is discharged outside by the groove (42) and the deflation hole (44) of head (4).
Then, under this state, press top cover (6), then sliding panel (5) is toward lower slider, and at this moment, the space of bleeding (A) enlarged.At this moment the space of bleeding (A) is vacuum state, and the air in the container (2) can flow in the space of bleeding (A).
Sliding panel (5) is when lower slider, and compression spring (8) enlarges the space of bleeding (A) under the vacuum state on the one hand on the one hand.At this moment, along with the vacuum of the space of bleeding (A), air pressure is higher than inrush of air in the container (2) of the space of bleeding (A) space (A) of bleeding.
That is, the air pressure in the container (2) is higher than the air pressure of the space of bleeding (A), between container (2) and the space of bleeding (A) draught head has been arranged, and the air in the container (2) is opened by sucking-off hole (33) and detected valve (46).Like this, the air in the container (2) flows into the space (A) of bleeding by sucking-off hole (33) and sucking-off hole (45).
In the space of bleeding (A), entered under the air state, removed and press the pressure of sliding panel (5).At this moment, sliding panel (5) up slides under the restoring force effect of spring (8).Then, the groove (42) of air by head (4) of bleeding in the space (A) is discharged to the outside.
Shown in Fig. 5 a, under the restoring force of spring (8), sliding panel (5) up slides.At this moment, the air of bleeding in the space (A) is up carried seal ring (43) by micro gap (I).Between the bottom of the groove (42) of the neighboring of the inwall (51) of sliding panel (5) and head (4), be provided with micro gap (I).On the other hand, seal ring (43) is close to the inwall of sliding panel (5).Friction coefficient between the inwall (51) of seal ring (43) and sliding panel (5) is very big.So sliding panel (5) is when up sliding, seal ring (43) is along with up moving, to open micro gap (I).Then, the air of bleeding in the space (A) is discharged outward by micro gap (I) and deflation hole (44).
Seal ring (43) in the groove (42) is up moved by the application force of above-mentioned two aspects.In groove (42), micro gap (I) and deflation hole (44) interconnect.Like this, the bleed air in space (A) is discharged to the outside under the restoring force of spring (8).
When air in the space (A) is bled in discharge, consider following problem.Bleed space (A) when enlarging under vacuum state again, and extraneous air can not flow in the space (A) of bleeding by deflation hole (44), groove (42) and micro gap (I).
That is, sliding panel (5) is when the lower slider, and compression spring (8) enlarges the space (A) of bleeding on the one hand on the one hand.At this moment, the air pressure of the space of bleeding (A) is lower than external pressure, also is lower than container (2) internal gas pressure.Extraneous air may occur and flow in the space (A) of bleeding, bleed two kinds of phenomenons in space (A) of the inrush of air in the container (2).The phenomenon that inrush of air in the container (2) is bled in the space (A) illustrated in the above that leaked-in air was discharged to the outside by deflation hole (44).Air outside flows into when bleeding space (A), and at first extraneous air acts on seal ring (43) by deflation hole (44).Seal ring (43) externally moves on to the bottom of groove (42) under the application force of air by force.Seal ring (43) is externally under the application force of air, blocks the micro gap (I) between the inwall (51) of head (4) and sliding panel (5) by force.
Also have, shown in Fig. 5 b, sliding panel (5) is when moving down, because the friction coefficient between the inwall (51) of seal ring (43) and sliding panel (5) is very big, so sliding panel (5) is during toward lower slider, seal ring (43) moves down along with past.At this moment, seal ring (43) is blocked micro gap (I) equally by force.Because seal ring (43) is blocked micro gap (I), so the air that flows in the groove (42) can't flow into the space of bleeding (A).
As mentioned above, to flow into the phenomenon in the space (A) of bleeding be non-existent to extraneous air.
The above effect of bleeding is to lean on the restoring force air-out of spring (8).It has very big sucking-off power.
Keep on the above operation of finding time, with the air in the sucking-off container (2).The article of being taken care of can be taken care of long-term effectively at vacuum state.
The article of taking care of in order to take out need be opened lid (1), at this moment, because be vacuum state in the container (2), so be difficult for opening.At this moment, use air getter assembly (7), make container (2) can suck extraneous air.Like this, can open lid (1).
That is, press the pressing plate (72) of air getter assembly (7).At this moment, spring (73) is compressed, and starting valve (71) is toward moving down.The seal ring (75) of the bottom of starting valve (71) unlocks from the projection (35) of body (3).Extraneous air enters in the container (2) by the air-breathing groove (74) of the neighboring of starting valve (71).
Container has flowed into extraneous air in (2), has reached certain air pressure, at this moment, could separate lid (1) from container (2).
That above-mentioned sucking-off hole (33) and suction hole (32) are done is air-breathing, during scavenging action, filter (34) plays multiple filtration.
In addition, airtight between the inwall (51) of head (4a) neighboring and sliding panel (5) as shown in Figure 6, be provided with on the deflation hole (44a) of head (4a) and detect valve (49), detect valve (49) and play scavenging action.
At length see the present invention, press sliding panel (5), can make the space of bleeding (A) form vacuum.Air in the container (2) sucks the space (A) of bleeding.Under the restoring force of spring (8), the air exhaustion outside in the exhaust space (A).Utilize minimum energy just can implement vacuum operation.Can realize practicality, convenience, high efficiency vacuum container cover (1).
By using vacuum container cover (1), no matter teas still is other numerous food, under vacuum state, can be taken care of long-term effectively, and therefore, the present invention has a lot of benefits and higher work efficiency.So, be a kind of can widely usedly the invention.
