Abstract

The utility model relates to a novel cork of thermos, which is composed of an upper cover, a spherical valve, a casing, and an o-ring seal. The utility model is characterized in that the thermal insulation effect of the utility model is good; the cork does not need taking off; the phenomenon that the cork is jumped up, and the thermos explode can not occur; the cork can not be easy to stick scale, not easy to corrode, age, and rupture, and has long service life, avoiding hands be polluted by touch, and the utility model an ideal cork of thermos.

Description

Cork of thermos

The utility model belongs to small stores.

The plug for vacuum bottle that existing market is sold has cork and plastic plug, after use a period of time, and cork contact water surface place, perishable, plastic plug contact water surface place, easily deteriorating aging breaking, service life is short, and easily produces dirt, and it is poor to be incubated.When the tight plug of lid, producing takeoffs comes off, and causes the thermos flask blast when serious.When pouring, must take off plug, cause hand migratory stain.

The research the purpose of this utility model is, designed a kind of novel heat insulation thermos cork, solved prior art exist perishable, deteriorate agingly break, service life is short, easily produce dirt, hand touches pollutions, insulation is poor, easily takeofing comes off and cause the deficiency that thermos flask explodes seriously the time.

Principle of design of the present utility model is, it is made up of loam cake, ball valve, housing and O-ring seal, and the part that during use bottle stopper is had the conical surface is filled in the thermos flask mouth, and at this moment ball valve is closed, and spheroid and valve seat contact position generate moisture film.When the thermos flask internal gas pressure exceeds ball valve pressure, back down ball valve.When pouring, bottle stopper must not taken off, ball valve is opened voluntarily, and water flows out from the discharge port on the housing, and pouring finishes, ball valve is closed voluntarily.

A kind of novel heat insulation thermos cork of the utility model, compared with the prior art, owing to designed ball valve and O-ring seal structure, high insulating effect, be difficult for causing that plug takeoffs comes off and thermos flask blast, simple in structure, parts are interchangeable in addition, must not take off bottle stopper during pouring, avoided hand to touch and polluted and generation pickup dirt.

Description of drawings:

This figure be a kind of novel heat insulation thermos cork structure principle chart wherein: 1, loam cake, 2, spheroid, 3, housing, 4, O-ring seal, 5, discharge port, 6, valve seat.

Below in conjunction with description of drawings, most preferred embodiment of the present utility model is made up of loam cake ball valve, housing and O-ring seal.Form ball valve by spheroid (2) and valve seat (6), spheroid in the ball valve (2) cooperates with housing (3) inner chamber valve seat (6), loam cake (1) miner diameter end is pressed into housing (3) upper end internal diameter and fixes, bigger diameter end bottom surface and housing, (3) the upper end women's head-ornaments engage, have two discharge port (5) in housing (3) upper half circle symmetry, O-ring seal (4) inwall of being made by nontoxic rubber is processed into spill, the outside face bottom is tapered, sealing cushion rubber (4) is inserted in the annular groove of housing (3) lower part, it is raw MAT'L that housing (3) and loam cake (1) adopt plastics or corrosion-resistant steel, and it is raw MAT'L that spheroid (2) adopts glass.
