Heating a consumable containing tobacco (or other plant material) without combustion to release smoke free vapors. A consumable having one or more deformable frangible sections is insertable into a chamber in a heating device with at least temperature controlled heating. During insertion of the consumable into the device, a protrusion deforms a frangible section(s) of the consumable which forms an air gap in a separation between the deformed section of the consumable and the chamber's inner wall. A controller receiving temperature sensor(s) input controls the supply of power to heating elements in thermal communication with the chamber thereby heating the consumable.

Heating a consumable containing tobacco (or other plant material) without combustion to release combustion free vapors. A consumable having one or more deformable frangible sections which bend inward upon insertion into a chamber thermal communication with at least one heating element with at least one controller and one sensor to control temperature during heating. When the consumable is inserted into the device, a protrusion deforms a frangible section(s) of the consumable which creates an axial air gap forming a separation between the deformed section of the consumable and the chamber's inner wall. The controller receiving temperature sensor(s) input controls the supply of power to one or more heating element in thermal communication with the chamber thereby heating the consumable.

A heating lunch box includes a food box for accommodating food, a heating module for heating the food box, an interaction module, and a processor coupled to the heating module and the interaction module. The processor is configured for performing the following operations: obtaining a power-on instruction, in response to the obtained power-on instruction, controlling the interaction module to display an initial interface, and the initial interface at least including a first time setting control; when a trigger event of the first time setting control is detected, controlling the interaction module to display a time selection interface; obtaining a set time from the time selection interface; controlling the interaction module to display a heating interface based on the set time; and driving the heating module to heat the food box.

Quite often it is heard that people complain about having cold food at their places of work. The problem is not localized to a particular geographic area or age, it affects everyone who prefers having hot food at workplace or college. The Smart Lunch box aims at providing hot food to users anytime and anywhere they want. It uses heating elements along with microcontrollers powered by batteries to provide heat even in the absence of a power outlet. The batteries have to be sufficiently charged well before hand, the box can be controlled to set temperatures and timer through a mobile application which simplifies the user interface and also reduces human intervention. The box can also be used as a noodle maker by using hot water. The technical applications are immense. This invention can be of great help to various working sects of the society.
