Description
Technical field
The utility model relates to a kind of holding vessel more particularly to a kind of self-evacuating vacuum holding vessels.
Background technique
It is mostly currently on the market tinplate storage tank, plastic packaging bag, carton box for storing the device of tealeaves and other items such as
Deng packaging, repeatedly take store object when, due to needing to uncap or be open, so that air enters, and can not all be discharged, make
It must store that object is oxidizable, the storage object after oxidation affects quality itself, if tealeaves is contacted with oxygen, will cause mouthfeel after oxidation
Decline, the improper meeting moisture absorption that is also possible to of storage is mouldy, breeds bacterium.
Utility model content
The purpose of this utility model is just to provide for a kind of self-evacuating vacuum holding vessel.
The utility model is that a kind of self-evacuating vacuum holding vessel is attained in that using following technical solution,
It is characterized in that, including tank body, sealing cover, piston cylinder, spring, the first tongue piece, the second tongue piece, sealing cover lid is located on tank body, close
Be provided with installation cavity in capping, piston cylinder is arranged in the installation cavity, and piston cylinder is connected with installation cavity, at the top of piston cylinder and
The installation cavity bottom of sealing cover is connected by spring, is provided with the first tongue piece at the top of piston cylinder, the installation cavity bottom of sealing cover is set
It is equipped with the second tongue piece, is provided with sealing ring between piston cylinder and the installation cavity of sealing cover.
Sealing cover is screwed on tank body.
Sealing cover is the typical lids with gasket.
Tank body is single layer tank body, is also possible to double layers of tank body with dissection.
The interlayer of double layers of tank body is to vacuumize interlayer.
The utility model is using the above-mentioned attainable beneficial effect of technical solution:
1, article is solved during storage due to frequently opening, air cannot be discharged in time, cause to store object (such as tea
Leaf) oxidation, the case where quality decline or mould growth.
2, the storage time of storage object is improved, it is ensured that the quality that the article (such as tealeaves) of long term storage has been able to maintain.
3, it can be carried around, it is more convenient, storage object, and the sky that can be simply and effectively discharged in holding vessel are extracted at any time
Gas.
Detailed description of the invention
Fig. 1 is a kind of self-evacuating vacuum holding vessel single layer tank body half section structure diagram of the utility model；
Fig. 2 is a kind of self-evacuating vacuum holding vessel double layers of tank body half section structure diagram of the utility model.
Wherein, 1- tank body, 2- sealing cover, 3- piston cylinder, 4- spring, the first tongue piece of 5-, the second tongue piece of 6-, 7- gasket,
8- sealing ring, 9- liner.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by way of examples.
As shown in Figure 1, a kind of self-evacuating vacuum holding vessel, including tank body 1, sealing cover 2, piston cylinder 3, spring 4, the first tongue piece
5, the second tongue piece 6, the lid of sealing cover 2 are located on tank body 1, and installation cavity is provided on sealing cover 2, and the setting of piston cylinder 3 is being installed
Intracavitary, piston cylinder 3 is connected with installation cavity, and 3 top of piston cylinder is connect with the installation cavity bottom of sealing cover 2 by spring 4, piston
3 top of cylinder is provided with the first tongue piece 5, and the installation cavity bottom of sealing cover 2 is provided with the second tongue piece 6, piston cylinder 3 and sealing cover 2
Sealing ring 8 is provided between installation cavity.
Sealing cover 2 is screwed on tank body 1.
When being pressed downward to the application of piston cylinder 3 external force, the first tongue piece 5 is upwardly opened, and the second tongue piece 6 is closed downwards, piston
Cylinder 3 inner airs discharge, when removing external force (while the first tongue piece 5 is closed), piston cylinder 3 is acted on by the elastic force of spring 4, to
Upper movement, because of gas expansion, piston cylinder 3 is connected with installation cavity and air pressure decline, the second tongue piece 6 are opened upwards in the cavity that is formed
It opens, the air inside tank body 1 is discharged into the cavity that piston cylinder 3 is connected with installation cavity and is formed, and passes through the circulation of piston cylinder 3
Gradually the air inside tank body 1 is discharged for movement, vacuumizes to realize to air in tank body 1.
Sealing cover 2 is the typical lids with gasket 7.
Tank body 1 can be single layer tank body, or and it is as shown in Figure 2 with double layers of tank body with dissection, i.e., it is set in tank body 1
There is liner 9.
Spring 4, the first tongue piece 5, piston cylinder 3, sealing cover 2, sealing ring 8, the second tongue piece 6 can be made detachable structure,
It may be alternatively configured the structure of overall applicability.
Spring 4 can have to be processed by materials such as stainless steel, spring steel, spring force 20-40N.
First tongue piece 5, gasket 7, sealing ring 8, the second tongue piece 6 can be made of silicon rubber.
Piston cylinder 3, sealing cover 2 can be made of materials such as ABS, HDPE, PA, PP, but be not limited to these types of material.
Tank body 1, the used material of single layer tank body can be tinplate, aluminium alloy, plastics etc.；The tank body of double layers of tank body material
Inside and outside two layers can all be glass, and the interlayer of double layers of tank body can be to vacuumize interlayer, have good insulation effect.
The utility model is not limited to above embodiment, and anyone skilled in the art can all make a variety of modifications and change
Change, under the spirit for not departing from the utility model, all in the utility model scope of the claimed.
