Abstract

A portable coffee brewing device includes a lid pivotally connected to an upper end of the container by a hinge and button. A heating element housing and an electrical component housing is connected to a lower end of the container. A drain is positioned in a bottom wall of the container and is fluidly connected to a heating element positioned within the heating element housing. The heating element is controlled by electrical components positioned in the electrical components housing. A drip tube is fluidly connected to the heating element and the lid. A single serve coffee holding device is positioned below the lid. When the container is filled with fluid and the heating element is powered, heated fluid is forced up the drip tube through the passageway in the lid and into the coffee grounds holding device in a continuous cycle. The device is connectable to an external power source.

Claims

1. A portable coffee brewing device comprising:

a container;

the container having a sidewall that extends from an upper end to a lower end;

the container having an first chamber;

wherein the first chamber is configured to receive water prior to brewing;

the container having a second chamber;

wherein the second chamber is configured to receive water after brewing;

a lid;

the lid operably connected to an upper end of the container;

a cover;

the first cover operably connected to the lid;

the first cover configured to move between an open position and a closed position;

a basket;

the basket operably connected to the container;

a coffee grounds holding device operably held by the basket;

the coffee grounds holding device having a wall that forms a hollow interior, an amount of coffee grounds held within the hollow interior of the coffee grounds holding device, and

a covering that covers the hollow interior of the coffee grounds holding device;

a hot water tube assembly;

the hot water tube assembly fluidly connected to the first chamber;

a nipple;

wherein the nipple is configured to penetrate the coffee grounds holding device when the cover is moved to a closed position;

a heating element;

the heating element configured to heat water during a brewing process;

a pump;

wherein when the first chamber is filled with water and the pump and heating element are powered, fluid moves from the first chamber, through the hot water tube assembly, through the coffee grounds holding device and into the second chamber, thereby brewing coffee.

2. The device of claim 1, wherein the hot water tube assembly includes a lower section, an upper section and a pivot section.

3. The device of claim 1, wherein the pump is an air pump.

4. The device of claim 1, wherein the pump is a water pump.

5. The device of claim 1, wherein when activated, the pump pressurizes the first chamber thereby forcing water within the first chamber through the hot water tube assembly.

6. The device of claim 1, wherein the nipple is operably connected to the cover such that when the coffee grounds holding device is held by the basket and the cover is moved to a closed position, the nipple penetrates the coffee grounds holding device.

7. The device of claim 1, further comprising a second nipple operably connected to the basket, wherein when the coffee grounds holding device is held by the basket and the cover is moved to a closed position, the second nipple is configured to penetrate the coffee grounds holding device.

8. The device of claim 1, wherein the second chamber is held within the container in a removable manner so as to facilitate removal and cleaning of the second chamber.

9. The device of claim 1, wherein the pump is connected to a vent, wherein the vent facilitates air flow to the pump.

10. The device of claim 1, further comprising an electrical socket positioned in the portable coffee brewing device and connected to an external power source thereby powering electrical components of the portable coffee brewing device.

11. The device of claim 1, wherein the hot water tube assembly is removable for cleaning purposes.

12. The device of claim 1, wherein the hot water tube assembly is fluidly connected to the nipple.

13. The device of claim 1, wherein the basket is held within the lid.

14. The device of claim 1, wherein the basket is formed within the lid.

15. The device of claim 1, wherein the lid includes a collar, wherein the collar connects to the container through threaded engagement.

16. The device of claim 1, wherein the cover is connected to the lid by a hinge.

17. The device of claim 1, further comprising a drain positioned in a bottom wall of the first chamber, the drain having a one way valve.

18. The device of claim 1, wherein the heating element is positioned below the first chamber.

19. The device of claim 1, wherein water passes through the heating element between the first chamber and the second chamber during brewing.

20. The device of claim 1, wherein the pump is positioned between the first chamber and the second chamber.

21. The device of claim 1, wherein when activated, the heating element heats fluid within the hot water tube assembly.

22. The device of claim 1, wherein the portable coffee brewing device is powered by an on-board power source, wherein the power source is formed of one or a plurality of batteries.

23. The device of claim 1, further comprising a second cover operably connected to the lid, the second cover configured to cover a pour spout.
