Description

Fever cup

The present invention relates to a heat generating cup, and more particularly, to a heat generating unit for generating heat through an induced current generated by a magnetic induction (WPC; Wireless Power Consortium), the contents contained in the cup (eg, water) , Coffee, green tea, etc.) to ensure that you can always drink warm.

In general, portable electronic devices such as mobile phones, PDAs, notebook computers, PMPs, MP3s, DMBs, cameras, etc. all use batteries.

Therefore, a separate charging device is required to charge the battery used in portable devices. In general charging system, the commercial voltage (AC 110 ~ 220V) is down and full-wave rectified, and the output terminal of DC voltage is connected to the terminals of battery. It is configured to be charged.

However, in the terminal supply method, when the charger and the battery are combined or separated from each other, the terminals on both sides have different potential differences, which causes a momentary discharge, and foreign matters accumulate on the terminals. Since there is a problem that degrades the life and performance of the charger and battery, such as a natural discharge, when the terminal containing the battery to be charged to the upper portion of the primary coil is located, it is induced from the inductor power by the secondary coil of the battery by the magnetic field. Solid-state chargers for charging electricity have been developed.

However, such a conventional contactless charger only provides power to the portable terminal and cannot be used for other purposes, thereby limiting its practicality.

Related technologies include Patent No. 0564256 "Pads and Battery Packs for Wireless Charging with Radio Frequency Identification Technology", Patent No. 0603864 "Battery Packs for Wireless Charging", Patent No. 051635 "Concave Pads for Wireless Chargers," Patent No. 0971748, "Near Wireless Power Transmission System," Patent Application No. 2008-0023483, "Wireless Power Transfer Device and Wireless Charging System Using the Same," Patent Application No. 2005-0053584, "Wireless Charging Device and Control Method thereof," and the like. have.

The conventional mobile phone charging system charges the battery using the power flowing through the plug while the mobile phone is mounted on the charger. In the conventional wired charging system, the use radius is determined according to the length of the line between the power outlet and the charger. If the installation site is complicated due to the handling of the wire and there is an error in the contact point, there was a problem that the smooth charging is not made or a failure occurs due to poor contact.

In addition, the non-contact charging system by magnetic induction has a problem that the limitation of the inductive coupling distance between the transmitter and the receiver and the bulky problem.
