The embodiment of the present application solves to seal object vacuum guarantor up for safekeeping for various in the prior art by providing a kind of vacuum freshness retaining cover
It is fresh, it is cumbersome, and the problem of air extracting seal effect difference.
In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
It states technical solution to be described in detail, it should be understood that the specific features in the utility model embodiment and embodiment are to this Shen
Please technical solution detailed description, rather than to the restriction of technical scheme, in the absence of conflict, the application is real
The technical characteristic applied in example and embodiment can be combined with each other.
Referring to Fig. 1, a kind of vacuum freshness retaining cover, including：Cover body 1 and exhaust sealing plug 3.
Exhaust sealing operating surface is opened up on cover body 1, is arranged in the exhaust sealing operating surface and is matched with the exhaust sealing plug
The first through hole of conjunction；Pumping and air inlet control are realized by exhaust sealing plug 3.
In general, exhaust sealing operating surface is arranged at the top of cover body 1, is a burnishing surface, is convenient for seal operation.
Specifically, exhaust sealing plug 3 includes：Soft seal end cap 31, connecting rod 34 and limit plunger 35.
Soft seal end cap 31 is covered on exhaust sealing operating surface, covers first through hole 22.
The body of rod of connecting rod 34 is arranged in first through hole 22, and the top of connecting rod 34 is fixed on the bottom end of soft seal end cap 31
On face, the bottom end of connecting rod 34 is located at outside first through hole 22 and is fixedly linked with limit plunger 35.
The radial width of limit plunger 35 is more than 22 diameter of first through hole, to avoid it from passing through first through hole 22；And then
In vaccum-pumping equipment pumping process, soft seal end cap 31 is tensed by connecting rod 34, avoids the mistake with a distance from 22 upper end of first through hole
Greatly；When to ensure to terminate pumping, the end that soft seal end cap 31 is pressed on to first through hole 22 is acted on by 1 outer atmospheric pressure of cover body
Portion realizes automatic-sealed；Its sealing reliability higher.
In general, intake and exhaust through-hole 32 is opened up on soft seal end cap 31, intake and exhaust through-hole 32 is located at first through hole
Outside 22 port areas.That is, being arranged the exhaust outlet of vacuum on soft seal end cap 31, pumping effect can be promoted
Rate, while in sealing, it is only necessary to relatively small intake and exhaust through-hole 32 is pressed on exhaust sealing operating surface, is operated
Simply, and under atmospheric pressure effect, sealing reliability is high.
For the ease of releasing vacuum sealing, lift-pull handle 33 is set on soft seal end cap 31, is operated by lifting, you can
Pull-up soft seal end cap 31 is connected inside and outside cover body 1.
The usually described soft seal end cap 31 uses rubber seal end cap or silica gel sealing end cap.
In general, limit plunger 35 is planchet structure；The radius of planchet is more than the radius of first through hole 22.
Sealing ring 4 is arranged in 1 bottom end of cover body, for sealing cover body 1 and smooth desktop, table top, and the end of glass or bulk container
Gap between the planes such as face, the reliability of lift-off seal.
The top of sealing ring 4 open up with the matched groove in the bottom end of cover body 1, the bottom end of cover body 1 is in groove, to protect
Demonstrate,prove the posture of sealing ring so that the reliability that cover body 1 seals.
In general, sealing ring uses rubber seal；Or inflation seal ring, hollow sealing ring so that sealing ring
Have enough stretch performances, to cope with daily desktop, table top etc. is not the object of stringent plane, and lift-off seal is reliable
Property.
In general, the quantity of intake and exhaust through-hole 32 is 3, it is uniformly arranged on soft seal end cap 31 with lift-pull handle 33.
In order to promote the efficiency of vacuum pumping, air extraction connector 2 is set on exhaust sealing operating surface, since connection vacuumizes
The connector of equipment.
In general, air extraction connector 2 is cylinder-like structure 21, and cylinder-like structure 21 is fixed on exhaust sealing operating surface,
It is connected to first through hole 22；Stable current path is formed, while also can constrain air flow path to a certain extent, is realized certain
At sealing effect.
Correspondingly, soft seal end cap 31 is embedded in cylinder-like structure 21, and in vacuum, soft seal end cap 31
Lift certain distance along cylinder-like structure 21 is axial, formed successively by cover body 1 inside, first through hole 22, intake and exhaust through-hole
32, the pumping path of cylinder-like structure 21.After vacuumizing, atmospheric pressure effect, soft seal end cap 31 presses to first rapidly
Through-hole 22, while realizing efficient sealed, reliability is stronger.It is highly efficient reliable relative to existing spring sealed structure.
In general, axial ledge 36 is arranged in the edge of soft seal end cap 31, on the one hand can reinforce soft seal end
The structural strength of lid 31 so that it keeps its form in vacuumizing, to seal first through hole rapidly after terminating to vacuumize
22；On the other hand, the contact area of soft seal end cap 31 and tubular construction 22, lift-off seal effect can also be increased.
Further, can be in 1 top inner wall of cover body, 22 lower end of first through hole extends inwardly to form an extension, from
And realize air-flow binding effect so that breathing action is realized with stable airflow shape, after being vacuumized convenient for promotion
Leakage efficiency and effect.
In order to promote the leakproofness of tubular structure 22 and vacuumizing joint, sealing spiral shell is opened up on the inner wall of cylinder-like structure 22
Line.
It is worth noting that the volume of cover body 1 is typically much deeper than existing fresh-keeping cover class formation, it is big simultaneously to adapt to it
The use demand of range sealing.
One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages：
The vacuum freshness retaining cover provided in the embodiment of the present application coordinates smooth desktop by the cover body that expands, table top or
Big container realizes that sealing on a large scale, bulky fresh-keeping product or various leftovers meal more for type are realized on the spot
Convenient vacuum sealing；More vacuum crispers are avoided to divide the troublesome operation preserved.Pass through soft seal end cap, connecting rod and limit
First through hole in the fit structure control soft seal end cap covering of plug；When vacuumizing, by being arranged in soft seal end cap
Intake and exhaust through-hole on end face is evacuated from inside to outside, and by connecting rod and limit plunger, soft seal end cap is avoided to be detached from；Stop taking out
When vacuum, soft seal end cap is pressed on by atmospheric pressure effect on exhaust sealing operating surface, realizes reliable sealing；When exhaust, turn over
Open rubber seal end face, you can realize that the pressure in cover body is adjusted, open cover body, simple operation.
It should be noted last that the above specific implementation mode is only to illustrate the technical solution of the utility model rather than limit
System, although the utility model is described in detail with reference to example, it will be understood by those of ordinary skill in the art that, it can be right
The technical solution of the utility model is modified or replaced equivalently, without departing from the spirit and model of technical solutions of the utility model
It encloses, should all cover in the right of the utility model.
