Each of these has individual benefit and each can also be used in conjunction with one or more, or in some cases all, of the other disclosed techniques. Accordingly, for the sake of clarity, this description will refrain from repeating every possible combination of the individual steps in an unnecessary fashion. Nevertheless, the specification and claims should be read with the understanding that such combinations are entirely within the scope of the invention and the claims.

[0020] In an embodiment, the temperature controlled mug, charging accessories and functions like voice activated control and use of disposable cups are discussed herein. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be evident, however, to one skilled in the subject that the present invention may be practised without these specific details.

[0021] The present disclosure is to be considered as an exemplification of the invention, and is not intended to limit the invention to the specific embodiments illustrated by the figures or description below.

[0022] The present invention will now be described by referencing the appended figures representing preferred embodiments. FIG. 1 depicts an exploded perspective view of the elements that comprise a temperature controlled mug (the “mug”) according to various embodiments of the present invention. It consists of lid (11) to tightly seal the disposable cup (12), metal container (13), with magnets (13A) attached at the bottom to secure the metal container, thermal insulating container (14) is around the metal container which has temperature sensors (14A) embedded in insulating container. Insulating container can be made of various insulating material and can also be vacuum insulated. Thermal pad (15A) is seated on the base assembly also called as thermal unit (15) which consists of thermostat (35) (Shown in FIG. 4), heating element (33) (Shown in FIG. 4) and temperature sensor (34) (Shown in FIG. 4). FIG. 1 shows thermoelectric cooler (16A) and heatsink (16), which helps maintain the desired temperature. Inside the heatsink is the fan (17) which helps to transfer heat. Underneath heatsink are batteries (18), and control element (Not shown in diagram for simplification). The assembly is covered by mug cover (19) which can be made of plastic or metal and has perforation (19A) for air flow.

[0023] Mug also has OLED display (20), UP button (21), DOWN button (21A) and power button (22) for controls. Above the OLED screen is the opening for microphone 36 for voice activated controls. The mug has wireless contact with charger (Automobile Charger and Desktop charger). The charging base (23) has two circuit connection positive and negative supply (23A) and magnet (24) in center for proximity sensing. This magnet activates the circuit on the charger so the power is turned ON.

[0024] FIG. 2 consists of lid (11) and disposable paper cup (12), lid (11) closes the opening of the disposable paper cup so the liquid is spill proof. Although the mug can be used without disposable cups to maintain the temperature, adding disposable cup in the mug to maintain the temperature gives advantages of not washing the mug everytime the liquid needs to maintain temperature. The lid (11) consists of push button opening to open and close access the liquid. Push button open and close operation is based on spring and switch operation not explained in this article for simplicity.

[0025] The metal container (13) inside the mug is removable was washing purposes if necessary. Three magnets (13A) placed underneath the metal container (13) confirm the alignment and helps tightly securing the base of metal container to the thermal unit. Most important, the powerful magnets are used for better thermal contact. For better thermal transfer between metal container and thermal unit, thermal pad (15A) is added on the top of the thermal unit. Refer FIG. 3 for details. The thermal pad (15A) can be used multiple times and have longer life. The thermal unit (15) has three holes for magnets from the metal container (13) to be aligned. Metal container can hold hot as well as cold liquid, if the liquid that is hot and temperature needs to be dropped down to specific value, the thermal unit (15) turns cold and bring the temperature down as per set point specified by user. Similarly in case where liquid is cold and needs to be warmed up, the thermal unit (15) turns hot and stays hot until the set temperature is reached. The metal container can be made to the size required to adjust the disposable cup.

[0026] FIG. 4 shows thermal unit (15) along with heatsink (16) and fan (17). This particular view in the figure shows the heating element (33), thermostat (35) and temperature sensor (34) embedded in thermal unit (15). Efficient heater is added to thermal unit so the thermo electric cooler doesn't have to operate all the time while warming the liquid. As thermoelectric cooler (16A) are not very efficient, heater do very fantastic job of heating with higher efficiency extending battery capacity. Plus heaters are very useful in avoiding condensation and frost accumulation on the heatsink, fan, control unit (38) and battery. Heatsink and Fan attached to thermoelectric cooler (Peltier cooler) helps to dissipate heat when liquid needs to be cooled.

[0027] Block diagram shown in FIG. 5 shows how controls are provided in order to make temperature control mug operational. Control Unit (38) uses power from chargers and onboard battery (18) as per conditions. Temperature sensors located across various points in the mug provide very useful information in terms of temperature and level of the liquid in the mug. Input switch like power button (22), UP button (21), DOWN button (21A) provides useful information to the control unit (38) in terms of temperature set point adjustment and powering ON and turning OFF the mug. Output elements in block diagram are OLED display (20), thermoelectric cooler (16A), heating element (33) and fan (17). Control unit (38) based on the inputs decides how the output element needs to be turned ON and OFF. Final goal of the control unit (38) is make sure the temperature is controlled as per set point and continue to operate safely. Thermostat (35) is added on the thermal unit for safety shut off when temperature on the thermal unit goes above safety limit.

[0028] Battery charger is needed to charge the onboard battery of temperature control mug and supply power to mug incase of low battery to maintain the operation. FIG. 6 shows automobile charger which can be placed in the cup holder of an automobile so the power could be supplied to the mug and help charge the onboard battery. FIG. 6 shows the automobile charger and in the center of the charger is opening 26 for cylindrical magnet located on the base of the mug. The center magnet not only helps in detecting if mug being placed on the charger but also helps to center align. Pogo pins on the outer ring (27) are for negative and inner ring (28) is for positive supply. Pogo pins helps to connect to the mug rails efficiently.

[0029] FIG. 7 shows desktop charger. Just like automobile charger, desktop charger is similarly used to charge the battery on mug and supply power for its operation. It does have base (29) support to rest on the flat surface. Although it is called desktop charger, the charger can be placed on any clean flat surface and hence can be used anywhere.
