Description

The vacuum freshness retaining tea can

Technical field

The utility model relates to a kind of tea can, especially a kind of vacuum freshness retaining tea can with good preservation.

Background technology

The tea can that our daily family uses all is common can, clomposite can and plastic bag packaging generally.But the fresh-keeping of tealeaves all the time can not be satisfactory, the qualitative change of very easy generation tealeaves.The tea can that has also occurred at present the improved prolongation tealeaves resting period on the market, these jars are even to be advanced and releases a jar interior air with covering of cover, is difficult to make have higher degree of vacuum in the jar, and tealeaves easily gives oxidation, the purpose of the real fresh-keeping tealeaves of out of reach.Tealeaves fresh-keeping depends primarily on the humiture of storage environment and the content of oxygen, and the oxidation that solves tealeaves is fresh-keeping primary means.It is necessary to develop a kind of jar that makes tealeaves remain vacuum storage for this reason.

Summary of the invention

The utility model provides a kind of simple in structure, easy to use according to the deficiency that existing tea can exists, good seal performance, and the high a kind of vacuum fresh-keeping pot for tea of degree of vacuum in jar makes a jar interior tealeaves long period that qualitative change not take place, and keeps original freshness.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of vacuum fresh-keeping pot for tea, comprise can body, cover, the part of bleeding, binding site at can body and cover is provided with seal ring, and the cover center forms cavity, and the part of bleeding is installed in the cavity, it is characterized in that the described part top jug of bleeding, handle connects piston rod, and piston-rod lower end is equipped with piston, and piston slides along the cavity inwall, there is the indent knock hole at the piston center, knock hole cooperates with the aie escape valve valve rod, and aie escape valve resistance lever runs through cavity base plate center aspirating hole, and aie escape valve and aspirating hole carry out fitted seal, cover cavity upper port connects stop collar, and the part of will bleeding is spacing in cavity.

In the technique scheme, described can body and cover engage to adopt and are threaded.

In the technique scheme, described aie escape valve comprises resistance lever, rubber spool, valve rod, and described resistance lever is positioned at the aspirating hole lower end, passes aspirating hole and is connected with valve rod, clamps the rubber spool in the middle of described resistance lever and the valve rod.

In the technique scheme, described valve rod is connected employing with the resistance lever and is threaded, and described valve stem tip is provided with symmetrical locating tab.

In the technique scheme, described rubber spool adopts silica gel material, and it is spherical that described rubber spool and aspirating hole hermetic unit are semicircle, cooperates accurate.

In the technique scheme, described knock hole inwall has two symmetries

The type groove, described

Type groove size and valve rod locating tab cooperate, and make the valve rod locating tab insert knock hole

Rotate flexibly in the type groove.

The utlity model has following advantage:

Vacuum is equipped with air extractor and realizes that extraction valve cooperates exquisite with aspirating hole in jar in cover, and sealing property is strong; The part integral structure of bleeding is simple, and it is really good to bleed, degree of vacuum height in jar, and the vacuum longer duration has prolonged the tea fresh keeping time greatly, and is very practical, and present technique also can be applicable to the fresh-retaining preserving of other food.

The specific embodiment

As shown in Figure 1, the utility model vacuum fresh-keeping pot for tea has can body 1, cover 2, aie escape valve 3, the part 4 of bleeding.Can body 1 and cover 2 engage to adopt and are threaded, cover 2 inner edges clip with can body and are connected leak free seal ring 5 for 1 mouthful, intracardiac one-tenth cavity 10 in the cover 2, there is aspirating hole 6 in cavity 10 bottom centre, the part 4 of bleeding is set in the cavity 10, cavity 10 upper port connect stop collar 7, and piston 402 is spacing in cavity 10.

As shown in Figure 1 and Figure 2, aie escape valve 3 comprises resistance lever 301, rubber spool 302, valve rod 303, resistance lever 301 is positioned at can body 1 inboard, resistance lever 301 runs through aspirating hole 6, is connected with valve rod 303, and valve rod 303 adopts with resistance lever 301 and is threaded, clip rubber spool 302 between resistance lever 301 and the valve rod 303, it is spherical that rubber spool 302 lower ends are semicircle, and rubber spool 302 carries out fitted seal with aspirating hole 6, and valve rod 303 top left-right symmetric have two locating tabs 304.

As Fig. 1, shown in Figure 3, the part 4 of bleeding is contained in cover 2 central cavity 10, and the part 4 of bleeding comprises knock hole 401, piston 402, piston rod 403, handle 404.Two symmetries are arranged in the knock hole 401

Type groove 405, Type groove 405 sizes and valve rod locating tab 304 cooperate, and make valve rod locating tab 304 insert knock hole 401 Rotate flexibly in the type groove 405.

The using method of the utility model vacuum fresh-keeping pot for tea:

The tealeaves of fresh dried is put into jar, cover cover 2 and tighten, the aie escape valves 3 of bleeding in the part 4 are in and do not have the nature of pressure closure state, the pulling part handle 404 of bleeding up, and piston 402 upwards produces attractive forces to aie escape valve 3 in the sliding process, make aie escape valve 3 and aspirating hole 6 produce the space, gas passes through aspirating hole 6 discharges in the tank body thereby make, the perseveration several, and gas is more and more thinner in jar, until producing negative pressure, make rubber spool 302 be close to aspirating hole 6 and seal.Squeeze grip 404 again, make valve rod 303 in knock hole

Type groove 405 inserts, and swing handle is fixed on valve rod locating tab 304 In the type groove 405, cover is difficult for opening.When need take out tealeaves, to hold handle 404 and up spur, piston rod 403 drives aie escape valve 3 and up carries together, and rubber spool 302 breaks away from aspirating hole 6, and this moment, ambient atmosphere entered in the jar, produces malleation and open cover 2 in jar.Swing handle 404 makes valve rod 303 break away from knock hole 401, can continue again to use.
