2. Background of the Invention
Cold beverages quench people's thirst and make them feel better and revitalized, especially in hot weather.
Generally speaking, cold beverages should be placed in a refrigerator to maintain their temperature. However, a refrigerator needs additional supplies, such as freon and external power source, to maintain a cold environment therein. In addition, the refrigerator must be adapted for its power source and its application is limited. And without a refrigerator, it is difficult to chill a beverage or maintain its cold temperature for extended periods of time.
Taking beer as an example, the colder a beer is, the better its taste. But if the beer is consumed over a long time period, the beer's temperature will gradually increase and the taste will become less pleasant. If ice cubes are added to lower the temperature of the beer, the beer will become diluted, spoiling the flavor and lessening the drinker's enjoyment of their beverage.

A cooling source 90 is disposed inside the cavity 132, such as ice cubes. The cover 14 encloses the opening 131 of the main body 13. In this embodiment, the main body 13 has an exterior layer 133, a middle layer 134 and an interior layer 135. The exterior body 123 is a layer made of a strong, durable product, such as reinforced plastic. The middle layer 134 is a heat insulation layer, such as Styrofoam. The interior layer 135 is a cooling layer, such as an aluminum material. Therefore, the structure of the main body 13 is firm and solid in order to maintain a low temperature. There are no limitations of the layers and the materials on the structure of main body 13. The tube 12 should be made of materials with excellent conductivity. The tube 12 is disposed inside the cavity 132. In this embodiment, the tube 12 is designed with a spiral shape to increase the surface area thereof. The tube 12 has an inlet “I” and an outlet “O” both secured to the housing 11, and the inlet “I” is higher than the outlet “O”, so that the beverage inside the tube 12 can flow downwardly naturally.
The position unit 20 has a base member 40, a control member 50 and a securing member 60. The base member 40 connects to the refrigeration unit 10 and has a passage 41 formed therein to communicate with the inlet “I” of the tube 12. The base member 40 has a shaft 42 that has a flowing hole 421 communicating with the passage 41. The flowing hole 421 is arranged with an angle ranging from 0 degree to 180 degrees. In this embodiment, the angle should be 90 degrees. The shaft 42 of the base member 40 is fitted to a sealing circle at the flowing hole 421 in order to prevent any overflow. The base member 40 includes a plug 43. The control member 50 includes a sleeve portion 51 pivoted to the shaft 42 of the base member 40, and a screwed tube portion 52 connecting the sleeve portion 51. The plug 43 orientates to the shaft 42 of the base member 40 and blocks the sleeve portion 51. The sleeve portion 51 of the control member 50 includes a though hole 511 that communicates with the passage optionally 40. The through hole 501 penetrates through the screwed tube portion 52. The sealing circle 53 is embedded at an exit “E” of the screwed tube portion 52 in order to prevent overflow. The securing member 60 is adjustably assembled to the control member 50 and orientated with a bottle mouth 81 of a bottle 80 to the control member 50, wherein the bottle mouth 81 communicates with the through hole 501. In this embodiment, the securing member 60 is U-shaped and includes a screw-mated portion 61, a groundwork portion 62 and a hook-mated portion 63 made integrally in one piece. The screw-mated portion 61 has a screw hole 611 mating with the screwed tube portion 52 of the control member 500. The hook-mated portion 63 has a cutout 631 which mates with a flange of the bottle mouth 81 in order to orientate the bottle mouth 81 to the exit “E” of the screwed tube 51 of the control member 50, and the bottle mouth 81 communicates with the through hole 501 via the exit “E”. The switch member 3 is secured to the refrigeration unit 10 via the securing member 31 and communicates with the outlet “O” of the tube 12. The switch member 3 can be any type of faucet.
With respect to FIGS. 1 to 4, the cooling source 90, such as ice cubes, is disposed inside the opening 131 of the housing 11 of the refrigeration unit 10. The cover 14 encloses the opening 131. The structure of the housing 11 guarantees a low temperature is maintained due to the ice cubes. The bottle 80 is secured to the position unit 20. The cutout 631 of the hook-mated portion 63 of the securing member 60 mates with the flange 81 of the bottle mouth 81 of the bottle 80. The securing member 60 can be rotated to lift the hook-mated portion 63 so that the securing member 60 is disposed at the exit “E” of the screwed tube portion 52 of the control member 50. Thus, the bottle mouth 81 can communicate with the through hole 501 of the sleeve portion 51 via the exit “E”. The bottle 80 is further pushed and lifted to rotate the control member 50, so that the through hole 501 aligns with the flowing hole 421 of the base member 40. The beverage in the bottle 80 flows into the passage 41 of the base member 40 by passing the through hole 501 and the flowing hole 421. The beverage further passes through the tube 12, is cooled immediately, and flows out of the switch member 3. Any part of the beverage that remains inside the tube 12 will be cooled. The base member 40 or the base member 11 can be further assembled with a relief valve (not shown) so that the beverage will flow out of the switch member 3 smoothly. The housing 11 or the base member 40 can be further assembled with a clamping apparatus (not shown) for holding the bottle 80.
FIGS. 5 and 6 show a second embodiment of the beverage-cooling device according to the present invention. An air-pumping unit 70 communicates with the passage 41 of the base member 40 of the position unit 20. The air-pumping unit 70 includes an pump 71 and piping 72. Two ends of the piping 72 connect to the pump 71 and the base member 40 of the position unit 20 respectively. This embodiment is particularly adapted for beer. The bottle 80 can be lifted to rotate the control member 50, and the pump 71 is used to pump air into the beverage. The air passes through the piping 72 to the passage 41 of the base member 40 and further into the bottle 80 via the flowing hole 421 and the through hole 501. Thereby the air mixes up with the beer to generate gas to thrust the beer into the tube 12. Therefore, the temperature of the beer is lowered, the air mixed into the beer makes the beer sweet, refreshing and the bubbles created by the infused the air gives the beer a desirable amount of bubbles or carbon dioxide.
The following are the advantages of the beverage-cooling device according to the present invention:

    
    
        1. The securing member orientates the bottle and the through hole so that it can communicate with the passage of the base member. This allows the beverage inside the bottle to easily flow into the tube of the refrigeration unit without the need for an additional power source. As such, use of the present invention is not limited by location or time. Furthermore, because the beverage is not diluted by cooling agents, such as ice cubes, the original concentration and flavor of the beverage is retained.
        2. Furthermore, the air-pumping unit pumps air into the beer to make the beer tasty and refreshing.
