Generally we have to drink hot water after we had food, to digest properly and to maintain our health properly. Also we need hot water to drink when we affected by cold or cough. But nowadays everywhere we will get cold water easily, in some hotels if customers ask hot water they boil the few amount of water. If we are in travel or in office or in college or somewhere except hotels and houses hot water is not available when we required. To avoid those problems, the present invention provides portable, compact, easy to carry heating article for a food or a liquid. The portable compact heating article can be used for heating or warming any water, beverages, semiliquid food, and semisolid food items. This is portable device, it fits inside our pocket.

In an exemplary embodiment of the present invention, Fig. 1 depicts perspective view of the portable heating article. The portable heating article 100 for heating a food or a liquid is disclosed. The article 100 comprising: a platform 101 for placing a container (not shown in the picture); an induction coil 102 place underneath of said platform 101; a rechargeable battery 104b to energize said induction coil 102; a switch 103 to start or shut-off said rechargeable battery 104b; a plurality of ports 108a, 108b, 108c for charging said rechargeable battery 104b; a Temperature adjusting buttons 103; a digital display 105 to indicate a temperature; and a solar panel 109 for charging said rechargeable battery. The container can made up of any material such as porcelain, china clay, stainless steel, steel, plastic, metallic, glass. Further, the container may have flat surface or curved surface, please note that flat surface takes less time to heat a food or a liquid filled in the container. The article 100 further comprises an attachment (ring type) structure 110 so when the container is place on to the platform 101, the container won’t move or displace easily. The diameter of the platform 101 can be less than 75 mm, so it can hold smaller container, mug or cup. The portable heating article which can heat water, beverages, soup, or any other food items filled inside the container. The food or said liquid comprises water, beverages, coffee, tea, soup, porridge, oats, astringency, noodles, dalia or any ready-to-eat food for which cooking/heating liquid is require. The article 100 can be shut-off either manually by pressing the switch 103 or alternatively the article 100 can be shut-off automatically once the pre-set temperature is attained. The portable heating article 100 has different type of charging points 108a, 108b, 108c. One charging point 108a is USB port and design to connect electronic devices via USB cables. Another charging point 108c is like cigarette charging plug, which can be used to charge the article while the user is driving the vehicle. Third charging point 108b is design to connect simple any normal charging adapter. The article 100 comprises LED indicator 107 which is green while the rechargeable battery 104b is supplying power to the induction coil 102 (means article is ON) which turns to red when the article 100 is OFF and the desire temperature is already reached by the article. The article 100 used rechargeable battery so the user can carry easily the heating article. Further, the rechargeable battery can be charge by various means, one of the means is solar source. Solar panel 109 is also fixed on the heating article, so it can provide energy source to the rechargeable battery. It will also help to save energy bills as well and during travelling when there is no charging facility is available, the solar panel will help a lot.

The portable heating article is help to heat little amount of water/beverages can heat through mug/cup. First the container is place on the platform, then the article can be turn ON by pressing the switch. Afterwards, the user can set the desire temperature by using the temperature adjusting buttons. While adjusting display will show the temperature status of manual adjustment, at require temperature set heating process by pressing both temperature adjustment button. The display will also indicate the current / real temperature of the container. Once the temperature is set-up then the LED glows (Green) which indicates that the heating article is ON. After heat reaches to the preset temperature, automatically heating process will stop. Manually, the user can also press same switch to turn-off the device. One can see temperature status through display with the help of processor (Micro controller) and input device. When the device is switched LED will not glow. While charging the device, LED will glow in red color to indicate it is in charging process. In the device circumstance solar panel is placed for self-charging or charging port is placed for alternative charging process. This device will suitable for all type of material, but heating will change for each materials. No need of any metallic surface to make connection with the coil. This device heat faster in flat surfaces, but in curve surface it will take time heat. In this device less than 75mm diameter cup/mug can place.
