Abstract

The utility model relates to an anaerobic beer fresh-keeping barrel, which comprises a beer barrel and a pump body. The pump is arranged in the beer barrel. The upper end of the pump is provided with a guide tube, and a piston and a connecting rod are arranged in the pump. The connecting rod extends out of the guide tube. The lower part of the pump body is provided with a beer outlet tube and a plurality of one-way beer inlet valves. The pump body is a double block structure which is connected through an inner screw thread and an outer screw thread. The barrel body is a step shape, and the central downward convex position is nested with the lower end of the pump body. When the beer is discharged from the utility model, the intake air is not needed; the external force is utilized to actuate the piston to move to cause the beer in the barrel to always lie in the of non-pressure loss state; the carbon dioxide is not oxygenized so the primary taste of the beer is maintained, and the fresh-keeping period is extended, and simultaneously the pump body has convenient disassembly and easy cleaning.

Description

Anaerobic beer refreshing bucket

The utility model relates to a kind of anaerobic beer refreshing bucket, belongs to the utensil of beer or beverage freshness remaining refrigeration usefulness.

The beer refreshing bucket of Shi Yonging in the market, staving adopts binary sectional construction processing and fabricating, Chinese patent CN2054018U, be that an air inlet valve is arranged above the bung of barrel of beer, when selling wine, need open air inlet valve, introduce vacuum in the fills with air bucket, wine just can flow out then, and its shortcoming of the barrel of beer of this structure is: behind the beer contact outside air, cause the carbon dioxide in the wine to reduce, directly influence beer flavor, shorten the fresh-keeping time limit, simultaneously in the airborne containment ingression wine, easily cause vinosity to pollute, influence health.

For overcoming above-mentioned shortcoming, the utility model has designed a kind of anaerobic beer refreshing bucket.Its design philosophy is: barrel interior beer is not contacted with air all the time, remove air inlet valve and can put wine under the situation that does not increase any gas, concrete scheme is achieved in that adorns a pump in barrel of beer, piston, connecting rod are arranged in the pump, connecting rod stretches out outside the barrel of beer, external force is pressurizeed to connecting rod, orders about piston motion, and wine is flowed out from wine outlet, the bottom of pump has a plurality of unidirectional wine inlet valves, when removing external force, unidirectional wine inlet valve is opened, and bucket advances wine in pump.

The utility model is simple in structure, easy to make, increase the pump housing in the bucket, can make beer be in not decompression situation always, solve the secondary pollution of air simultaneously, a barrel interior carbon dioxide is not overflowed wine, not oxidation, kept the deliciousness of beer original flavor, and prolonged the beer refreshing time limit, the pump housing is convenient to dismounting and is cleaned simultaneously.

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

Accompanying drawing is that vertically cuing open of the utility model pump shown scheme drawing.

Anaerobic beer refreshing bucket, it includes a barrel of beer 1 (part of only drawing) and wine outlet duct 8, it is characterized in that: pump 2 is arranged in the barrel of beer, pump housing upper end centre bit is equipped with guide pipe 3, piston 4 is arranged in the pump housing, piston side wall is embedded with seal ring 5, the piston upper end connects a connecting rod 6, connecting rod stretches out outside the guide pipe, and unidirectional wine inlet valve 7 and wine outlet duct 8 are arranged at pump housing bottom, the axis symmetry of the pump housing and barrel of beer, be upper and lower catamaran type structure, connecting by internal and external screw thread between binary, is stepped at the bottom of the barrel of beer, protuberance position and pump housing bottom nested under the center.Wine outlet duct 8 has negative thread, goes out wine switch 9 and has outside thread, and two parts enter the pump housing for preventing air from wine outlet duct by threaded connection, goes out the wine switch and is embedded with seal ring, enters in pump and the interlayer that staving combines for preventing beer, and seal ring is housed therebetween.

During use, earlier to the connecting rod pressurization, drive piston and move downward, advance the wine closed check valve, open the wine switch, beer flows out; When removing external force, unidirectional wine inlet valve advances wine, makes in interior beer of pump and the bucket to reach same horizon.

Present embodiment is to be the pump of the no end with pump housing upper design, and the bottom of pump is at the bottom of the U type pump 10, and the pump housing connects by internal and external threads with at the bottom of the pump, unidirectional wine inlet valve designs in pump housing bottom, the staving stepped portions, wine inlet valve can be arranged a plurality of at regular intervals, and best 4, small end of the present utility model adopts open core type, have negative thread, with have externally threaded weight and be connected, as the external force pressurization, external force can be manual, can realize automatically that also staving can be designed to different shape.
