Specific implementation mode
It is multiple to solve vacuumizing and exhausting apparatus structure in the prior art by providing a kind of vacuum refreshing lid for the embodiment of the present application
Miscellaneous, the sealing speed of response is low, the technical problem of sealing reliability and stability 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 and Fig. 2, a kind of vacuum refreshing lid, including：Lid 1 and the vacuumizing and exhausting structure being arranged on.
Specifically, vacuumizing and exhausting structure includes：Gas vent 2 and the exhaust sealing plug 3 to set within it；It is vented close
Blocking 3 is matched with the gas vent 2, realizes vacuumizing and exhausting, the function of sealing and depressurization.
Referring to Fig. 3 and Fig. 4, in general, exhaust sealing plug includes：Soft seal end cap 31 and connecting rod 34；It is soft close
Sealing end lid 31 is shelved on the port of gas vent 2, block gas vent 2.
The shaft of connecting rod 34 is placed in gas vent 2, the top of connecting rod 34 and the bottom face stationary phase of soft seal end cap 31
Even, the bottom end of connecting rod 31 is located at outside the bottom end of gas vent 2 and is arranged radially enlarged portion 35, and the radius in radially enlarged portion 35 is more than
The radius of gas vent 2；To ensure in vacuum, soft seal end cap 31 is without departing from lid.
Wherein, intake and exhaust through-hole 32 is set on soft seal end cap 31, and intake and exhaust through-hole 32 is located at the port of gas vent 2
Outside region.That is, when soft seal end cap 31 is pressed on lid, the port of gas vent 2 and intake and exhaust through-hole
32, by block, can not be vented, to ensure the sealing effect in box.When vacuumizing or releasing vacuum, soft seal end
Lid 31 lifts, and naturally forms in box, the current path of gas vent 2, intake and exhaust through-hole 32, has realized and vacuumized and release very
Empty function.
It is worth noting that when vacuum stops, the negative pressure of 31 top of soft seal end cap disappears, and is arranged
The effect of negative pressure in stomata 2 and box, soft seal end cap 31 fall the top to gas vent 2 and cover sealing, response efficiency rapidly
The significantly larger than sealing element of the prior art.Meanwhile entire seal process and state maintenance all rely on negative pressure state in box, because
The sealing element of the reliability and stability of this sealing compared with the existing technology substantially increases.
For the ease of operation, lift-pull handle 33 is set on soft seal end cap 31, by operating lift-pull handle 33, conducting row
Stomata 2 realizes that sealing releases.
In general, gasket 4 is set on the bottom face of lid 1, to realize compartmentalization sealing structure, for large mouth
Effectively sealing can be achieved in the container of diameter range or open shape.It is of course also possible to coordinate special keeping box body 6.Usually
Insure and matched lower seal 7 is set on the top end face of box body 6, dual face seals realize reliable airtight quality.
Gasket 4 is covered on 1 bottom face of lid, and opens up matching through-hole in 2 corresponding position of gas vent,
That is 4 ring pads structure of the gasket, is arranged on the bottom face of lid 1, sealing area is formed.In general, described close
The shape of packing 4 is consistent with the shape of 1 bottom face of the lid, can also be regular circle shapes or rectangular equal conventional vessels end
The shape of mouth.
For lift-off seal quality, opened up respectively on the bottom face of gasket 4 and the top end face of lower seal 7 matched
Seal screw thread.By the cooperation of thread seal thread, the sealing effect of interface is further promoted.
In general, gasket 4 and the lower seal 7 use the good rubber seal of elastic packing ability.
Generally for structural strength and exhaust efficiency is ensured, the quantity of intake and exhaust through-hole 32 is 3；Be distributed in it is soft
On end cover 31, concentration or the excessive influence structural strength of hole area are avoided.
In general, soft seal end cap 31 uses structural strength and the better rubber seal end cap of toughness balance.
Further, 2 top of gas vent is arranged to stepped hole, and stepped hole includes：Top limiting slot 21 and lower part venthole
22；Gas vent is divided into two parts up and down.Wherein, the zone radius of top limiting slot 21 is more than the half of lower part venthole 22
Diameter.
Soft seal end cap 31 is placed in top limiting slot 21, realizes limit；In general, the shape of top limiting slot 21
It is matched with soft seal end cap 31, and the zone radius of top limiting slot 21 is slightly larger than the radius of soft seal end cap 31, just
Make soft seal end cap 31 in top limiting slot 21 well, on the one hand ensures the shape of soft seal end cap 31 in vacuum
State, convenient for falling block lower part venthole 22 after rise；It on the other hand, also being capable of lift-off seal performance.Usual 31 He of soft seal end cap
Top limiting slot 21 selects circular configuration.
Correspondingly, the shaft of connecting rod 34 is placed in lower part venthole 22.
Further, axial ledge 36 is arranged in 31 edge of soft seal end cap, on the one hand ensures its structural strength, convenient for protecting
Its form is held, ensures block efficiency, while can also increase the contact area with the cell wall of top limiting slot 21, lift-off seal is reliable
Property.
Further, sealing screw thread is opened up on the cell wall of top limiting slot 21, promotes the sealing effect of vacuum pumping.
The present embodiment also provides a kind of vacuum crisper based on above-mentioned vacuum refreshing lid.
One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages：
The vacuum refreshing lid provided in the embodiment of the present application, by the lid of vacuum refreshing lid formed gas vent and
Matched exhaust sealing plug realizes vacuumizing and exhausting and seal operation；Specifically, it is covered and is arranged by soft seal end cap
Stomata, and intake and exhaust through-hole is set on it, when evacuated, soft seal end cap lifts certain distance naturally, and intake and exhaust are logical
Hole forms current path with gas vent, extracts the air in crisper out；Correspondingly, after completing vacuum pumping, soft seal
Negative pressure disappears above end cap, and by suction function in gas vent, soft seal end cap is real rapidly to gas vent whereabouts block gas vent
It now seals, response efficiency is high；And seal process is completely dependent on negative pressure in box, to which sealing effect and stability are very high；Even if long
Phase influences the defect of airtight quality using that such as the damage of seal structural part in the prior art will not occur.It is being covered by setting
Gasket on body bottom face realizes regional seal function, to cope with the container of various bore specifications, expands the scope of application.
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
