A beverage heating receptacle device for heating a beverage includes a shell, which defines an interior space and which is formed to define a receptacle having an annular sidewall that extends from a bottom to an open top. A beverage is positionable in the receptacle. A heating element is engaged to the shell and is positioned in the interior space proximate to an inner section of the annular sidewall and an upper section of the bottom. A base is selectively engageable to the receptacle so that the base extends from the bottom. A battery is positioned in the base and is operationally engaged to the heating element upon engagement of the base to the receptacle. The battery thus is enabled to selectively power the heating element to heat the beverage.

Disclosed are a multifunctional heating and heat preservation container and a charging base thereof. The multifunctional heating and heat preservation container comprises a container main body (30), with the container main body (30) comprising a container inner lining (8), and a container housing (10), which forms a vacuum cavity (9) with the container inner lining (8) and enables the bottom of the container inner lining (8) to be exposed, is arranged on the peripheral side of the container inner lining (8). The charging base comprises a base housing (1), an ejector pin (2), which is in contact with a charging ring (214), is arranged in the base housing (1), an insulating layer (3) is sleeved on the ejector pin (2), an elastic member (4) which elastically ejects the ejector pin (2) towards the outside of the base housing (1) to enable the ejector pin (2) to move out of or retract into the base housing (1) is sleeved on the insulating layer (3), and a conductive terminal (5) is connected to the ejector pin (2). The problems whereby a cup body of an existing temperature control cup uses a single-layer steel plate structure, the cup body dissipates heat quickly, and heat preservation completely depends on electric energy heating, such that a battery which is in the temperature control bottom of the container and is used for power supply consumes electricity quickly, are solved; and the problems whereby a spring in an existing charging base is arranged in an ejector pin, and the spring is prone to failure due to an overlarge current in the power-on process of the charging base with the outside, such that the ejector pin cannot rebound and reset, are solved.

The present invention relates to an assembly for the preparation of a heated beverage, comprising a case or cover or box (battery cover) (8) for mobile phone (60) or external device (6) comprising an internal seat for the corresponding insertion of at least a container (7), said container (7) comprising means (13) for the production of heat, wherein said container (7) comprises contacts (12) to electrically feed said means (13) when said container is inserted in the seat.

An actively heated or cooled mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed at least partially in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A user interface is electrically connected to the circuitry and has one or more selection members actuatable a) to turn off the one or more heating or cooling element or b) to adjust a temperature setting to one of multiple temperature settings configured to control the one or more heating or cooling elements to heat or maintain the liquid at a user selected temperature.

An apparatus is disclosed. The apparatus has an outer housing, an inner housing disposed in the outer housing and forming a gap between an exterior surface of the inner housing and an interior surface of the outer housing, one or more thermal devices disposed in the gap, and an electrical port disposed in or on the outer housing and electrically connected to the one or more thermal devices.

An electronic stove incorporates a cylindrical outer shell and a concentric copper heater core. A foil heater surrounds the copper heater core and a heater control PCB carried in the outer shell is connected to the foil heater. A battery assembly has a cylindrical second outer shell carrying a battery pack. A power controller carried in the second outer shell is connected to the battery pack. A connector carriage is engaged between the battery assembly and cylindrical outer shell, extending through the shell of the battery assembly and received in the cylindrical outer shell aligned proximate a lower surface of the first outer shell whereby the lower surfaces of the first outer shell and the second outer shell are in planar alignment. A first contact set of a connector is connected to the heater control PCB. A second contact is connected to the power controller.

A self-heating container assembly has a housing with a first portion and a second portion, each having a cylindrical cross-section. The first portion and the second portion are mated together in a manner that permits the first portion to rotate about a common axis relative to the second portion. A ring gear (or partial ring gear) is on or attached to the first portion and rotates with the first portion of the housing relative to the second portion. A rotatable cutting element is supported by a support connected to the second portion of the housing. There is a pinion gear on the rotatable cutting element. The pinion gear is coupled to the ring gear. A reactant container containing a reactant is adjacent to the rotatable cutting element, such that rotation thereof cuts into the reactant container.

An actively heated or cooled cup or mug has a body with a chamber that can receive and hold a beverage and a heating or cooling system disposed in a cavity below the chamber. The heating or cooling system has a heating or cooling element to actively heat or cool the chamber, power storage devices, and circuitry that controls the operation of the heating or cooling elements. A sensor can detect a presence of a liquid in the chamber, the circuitry configured to turn on power to the heating or cooling elements after said liquid is detected and further configured to automatically turn off power to the heating or cooling elements upon receiving a signal indicating that the liquid in the chamber has dropped below a predetermined liquid level or been depleted completely.

An electronic stove incorporates a cylindrical outer shell and a concentric copper heater core. A foil heater surrounds the copper heater core and a heater control PCB carried in the outer shell is connected to the foil heater. A battery assembly has a cylindrical second outer shell carrying a battery pack. A power controller carried in the second outer shell is connected to the battery pack. A connector carriage is engaged between the battery assembly and cylindrical outer shell, extending through the shell of the battery assembly and received in the cylindrical outer shell aligned proximate a lower surface of the first outer shell whereby the lower surfaces of the first outer shell and the second outer shell are in planar alignment. A first contact set of a connector is connected to the heater control PCB. A second contact is connected to the power controller.

An actively heated or cooled food container can have a lid movable between an open and a closed position and an insulated body to which the lid can be attached. The insulated body can have a sidewall that defines a perimeter of the container body and a base, the sidewall and base defining one or more chambers that can be sealed by the lid. The food container can have a temperature control system that can include one or more heating or cooling elements in thermal communication with one or both of the sidewall and the base and operable to heat or cool one or both of the sidewall and the base to thereby heat or cool the one or more chambers in the food container.
