Description

Wireless heating tumbler with high heat generation and high efficiency characteristics using heating wires with carbon conductive ink {HIGH HEATING AND HIGH EFFICIENCY WIRELESS HEATING TUMBLER WITH CARBON CONDUCTIVE INKHEATING WIRE} The present invention relates to a wireless heating tumbler. More specifically, it relates to a wireless heating tumbler that applies a carbon planar heating element having low power consumption and high heat generation characteristics. Generally, heating tumblers are used to hold beverages such as coffee, tea, herbal medicine, and water, or food such as soup and stew, inside to maintain or heat them at a constant temperature for a long time. In particular, conventional heating tumblers used aluminum-based etched foil as a surface heating element, which resulted in a low heating rate and required high power of 40W or more, thus requiring a wired connection. Accordingly, existing heating tumblers have a structure in which the power supply for wired connection protrudes outward, which significantly reduces the durability of the tumbler that requires cleaning after use, and thus has limitations that easily cause breakage and malfunction. In addition, the heating tumbler containing the battery experienced swelling due to indirect radiant heat being transferred to the battery as a result of the heating module. Consequently, a problem arose in which the tumbler could not perform its function as a heating tumbler because it is not designed to be replaceable, given the nature of the tumbler which is prone to breakdown and requires waterproofing. Therefore, in order to improve durability and airtightness, there is a need for the development of technology for a wireless heating tumbler in which the heating module of the tumbler is formed with a structure that is completely isolated from the external environment.
