Description

The beer refreshing kettle

Technical field

The utility model belongs to material reservoir vessel field, is specifically related to a kind of container that is used to store the drinks.

Background technology

On the summer beverage market, beverage often there is fresh-keeping requirement.For this reason, the container that holds beverage also should possess fresh-keeping function.When people drink draft beer, often with beer filling in big stein, this cup is placed on the dining table, so that in cuvette, pour at any time.There is tangible drawback in this stein, promptly the carbon dioxide in the beer be easy to excessive, long-time slightly after, the mouthfeel of beer and nutrition degree just reduce greatly.For a change this situation, the day for announcing is on September 21st, 1988, the patent No. discloses a kind of container that holds beer for the Chinese utility model patent " stein " of " 88203537 ", this container comprises an inner bag, wine outlet is offered on the top of inner bag, be provided with a lid at the top, thereby avoided overflowing of carbon dioxide.When toppling over, the control valve of opening the wine outlet place gets final product pouring.The defective of this stein is, when toppling over beer, need be by means of the air pressure of top in the kettle, otherwise just do not come out.Because the beer in the kettle contacts with air, thereby has influenced the nutrition degree and the fresh keeping property of beer, makes the fresh keeping time of draft beer too short.Be head it off, the applicant had once invented a kind of beer refreshing kettle, comprise kettle body and inner bag, wine outlet is offered on the top of inner bag, piston is set in inner bag, connects adjusting rod on piston, adjusting rod is positioned in the cavity of inner bag bottom, on the kettle body safety regulating valve is set, safety regulating valve is connected with the cavity of piston below.Though solved the beer refreshing problem, structure is too complicated, is difficult for making.

The utility model content

The technical problem that the utility model solved is: a kind of beer refreshing kettle is provided, and this fresh-keeping kettle can avoid the beer in the kettle to contact with air and easy manufacturing simple in structure when toppling over beer.

The technical scheme that its technical problem that solves the utility model adopts is: design a kind of beer refreshing kettle, comprise kettle body and inner bag, wine outlet is offered on the top of inner bag, it is characterized in that being provided with in the inner bag piston, the high pressure air cavity is set between kettle body and the inner bag, and the cavity of piston below is connected with the high pressure air cavity.

The utility model is provided with the safety valve that communicates with the high pressure air cavity on the kettle body, when the air pressure in the high pressure air cavity was excessive, safety valve was opened and pressure release.

For in inner bag, irritating wine, on the kettle body, connect the wine filling tube that communicates with inner bag, the wine filling tube first line of a couplet connects check valve.

After using a period of time, the gas pressure in the high pressure air cavity can reduce, thereby has influenced outside pouring, on the kettle body charge valve is set for this reason, and charge valve is connected with the high pressure air cavity; Get final product to the high pressure gas interacvity air-filling by charge valve after using a period of time.

For making the cavity air pressure equilibrium of piston below, pressure maintaining valve is set on inner bag, the cavity of piston below is connected with the high pressure air cavity by pressure maintaining valve; Check valve is set on the inner bag, and check valve is connected with the high pressure air cavity.

The beneficial effect that the utility model had is:

(1) is cavity between inner bag and the kettle body, charges into gas in the cavity in advance, owing in inner bag, be provided with piston, when pouring, piston moves under the effect of gases at high pressure, wine can be poured out, beer does not contact with air in whole process, has prolonged the freshness date of beer.

(2) owing to be provided with the safety valve that communicates with inner bag on the kettle body, when the cavity internal gas pressure was excessive, pressure release can open the safety-valve.

(3) the utility model can be widely used in doing on restaurant or the family's dining table stein use.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the structural representation of second embodiment of the utility model;

1. check valves among the figure, 2. wine filling tube, 3. pouring valve, 4. wine outlet, 5. inner bag, 6. high pressure air cavity, 7. safety valve, 8. kettle body, 9. piston, 10. aperture, 11. charge valves, 12. pressure maintaining valves, 13. check valves.

The specific embodiment

Embodiment one

As shown in Figure 1, inner bag 5 is set in the kettle body 8, forms high pressure air cavity 6 between kettle body 8 and the inner bag 5, wine outlet 4 is offered on the top of inner bag 5, inner bag is provided with piston 9 for 5 li, offers aperture 10 on the inner bag of piston 9 belows, and the cavity of piston 9 belows is connected with high pressure air cavity 6 by aperture 10.Connect the wine filling tube 2 that communicates with inner bag 5 on the kettle body 8, wine filling tube 2 first line of a couplet connect check valve 1.In inner bag 5, inject beer through wine filling tube 2,,, and can not flow backwards so beer can only inject inner bag 5 from wine filling tube 2 owing to connected check valve 1 on the wine filling tube 2.

Earlier high pressure air cavity 6 is vacuumized, irritate wine by wine filling tube 2 for 5 li to inner bag, piston 9 is displaced downwardly to inner bag 5 bottoms.Because in the high pressure air cavity 6 between kettle body 8 and the inner bag 5 is vacuum, thereby the fresh keeping time of beer is long.When needing outside pouring, in high pressure air cavity 6, charge into gases at high pressure by charge valve 11 earlier, open pouring valve 3 after, piston 9 moves upward under the effect of gases at high pressure, and beer is poured out.For preventing that air pressure in the high pressure air cavity 6 is excessive the beer refreshing kettle is caused damage, the utility model is provided with the safety valve 7 that communicates with high pressure air cavity 6 on kettle body 8, and when the air pressure in the high pressure air cavity 6 was excessive, safety valve 7 was opened and pressure release.

After using a period of time, the gas pressures in the high pressure air cavity 6 can reduce, thereby can influence outside pouring, must inflate in high pressure air cavity 6 by charge valve 11 after using a period of time for this reason.

Because the beer in the inner bag 5 does not contact with air all the time, thereby has prolonged the beer refreshing time.

Embodiment two

When opening the outside pouring of pouring valve 3, the air pressure of piston 9 belows is very big, and the impulse force when causing pouring is very big.For addressing this problem, can do improvement as shown in Figure 2, pressure maintaining valve 12 is set on inner bag 5, the cavity of piston 9 belows is connected with high pressure air cavity 6 by pressure maintaining valve 12.Owing to be provided with pressure maintaining valve 12, thereby make the stable gas pressure of piston 9 belows.Can adjust the air pressure of piston 9 belows at any time by the atmospheric pressure value of adjusting pressure maintaining valve 12.

When 5 li of inner bags were annotated wine, piston 9 can move down along inner bag 5 by wine filling tube 2, and when piston 9 moved to inner bag 5 bottoms, the air pressure of piston 9 belows can be very big, and air pressure is crossed conference and caused annotating the discontented situation of wine.For this reason, check valve 13 is set on inner bag 5, check valve 13 is connected with high pressure air cavity 6.The gas of piston 9 belows can flow in the high pressure air cavity 6 by check valve 13.

Pressure maintaining valve 12 in the present embodiment is a prior art, does not remake set forth in detail.Check valve 13 can combine with pressure maintaining valve 12.

Embodiment three

As a kind of equivalent of the utility model claim, can also be between kettle body and inner bag fill insulant material, in the bottom of inner bag dividing plate is set, pressure maintaining valve and check valve are set on dividing plate.This kind scheme reaches the technique effect that embodiment two is had equally.
