The second cover 70 selectively gets communicated with the space part 61 of the second body 60 depending on the rotation like the first cover 20 for thereby discharging the beverage from the space part 61.

A thread engaging part 400 is formed along the rims of an upper side of the second body 60 and the rims of an inner lower side of the second cover 70 for thread engagements. A thread engagement part 400 is formed along the rims of an upper side of the second cover 70 and the rims of an inner lower side of the first body 10 for thread engagements.

Like the first cover 20, the second cover 70 includes a lower body 71 having a first through hole 72 communicating with the space part 61 of the second body 60, an upper body 73 which is rotatably installed in an inner upper side of the lower body 71 and has a second through hole 74 which gets communicated with the first through hole 72 depending on its rotation, and a fixing shaft 75 for rotatably fixing the upper body 73 in the lower body 71.

When the first and second through holes 72 and 74 get communicated with each other as the upper body 73 rotates, the beverage can be discharged

from the interior of the space part 61. It is preferred that a rotation groove 76 might be formed on the upper body 73 for easily rotating the upper body 73.

The second cover 70 might be configured to open upon rotation like in a preferred embodiment of the present invention. Various opening methods such as a one-touch opening method might be used.

The second cap 90 is detachably thread-engaged on a lower side of the second body 60. When the second cap 90 is used with the first and second bodies 10 and 60 being connected, it is engaged to a lower side of the second body 60. When the second cap is used with the first and second bodies 10 and 60 being separated, it is engaged to the thread engaging part 400 of the second cover 70 for thereby protecting the second cover 70 while operating as a typical cup which is used for drinking.

The thread engaging part 400 is formed in a lower inner side of the second cap 90 like the first cap 30. A second heating member 80 is installed in a lower side of the second body 60 to which the second cap 90 is engaged. The second heating member 80 is to heat the beverage stored in the space part 61 of the second body 60.

Like the first heating part 40, the second heating member 80 includes a heating device 81 installed in a lower inner side of the second body 60, and a heating coil 82 which is electrically connected with the heating device 81 and is protruded inwardly toward the space part 61 of the second body 60 for thereby heating the beverage stored in the same.

The heating device 81 and the heating coil 82 are the same as the conventional heating device and heating coil. An externally extended power cord 200 is connected with the heating device 81 for thereby receiving electric

power.

The power cord 200 might be formed of a power cord 200 having a plug. As shown in Figure 7, a cigar jack 300 might be provided for the use in a vehicle.

The operations of the portable electricity thermos 1 according to an embodiment of the present invention will be described.

When the thermos of the present invention is used in a vehicle, the cigar jack 300 is inserted into a cigar jack terminal(not shown) of the vehicle.

When the first and second heating members 40 and 80 operate, the red lamp is turned on, and beverage is boiled. When the first and second heating members 40 and 80 stop, the red lamp turns off for informing the user of the stop operation.

When the yellow lamp is turned on, the user separates the power cord

200 or the cigar jack 300 for thereby stopping the supply of the power. The first and second through holes 22, 72 and 24, 74 get communicated by rotating the upper bodies 23 and 73 of the first and second covers 20 and 70 for thereby discharging the beverage from the space parts 11 and 61.

When it is needed to filter coffee beans or tea leaves using the filtering net 100, the second cover 70 thread-engaged to the second body 60 is opened, and the beverage is stored into the space part 61, and the power cord 200 is connected for driving the second heating member 80, so beverage is coiled.

The first cover 20 thread-engaged to the first body 10 is opened, and coffee beans or various tea leaves are inputted into the filtering net 100, and the filtering net 100 is supported by means of the engaging shoulder 13 of the space part 11 of the first body 10. The boiled beverage stored in the space part 61 of the second body 60 is poured into the space part 11 of the first body 10 in which the filtering net 100 is disposed, and the first cover 20 is engaged to the first body 10.

A certain time has been passed, and the beverage that passed through the filtering net 100 is discharged through the discharge pipe 51 by opening the engaging lid 52. At this time, an additional cup might be used, but it is preferred that the beverage is drunk using the first or second cap 30 or 90.

As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
