Benefits of technology

"The present invention provides a hand warmer that can easily ignite and extinguish using a simple method. The hand warmer includes a case with air holes, a heating body with an ignition section, a fuel tank, power supply section, and an electrical ignition means. The electrical ignition means includes a hot wire, electrode plates, and a switch knob. The hot wire is fixed to the electrode plates and the electrodes are connected to the fuel tank and power supply section. The power supply section has a voltage of about 1.5V to about 9V. The fuel tank is inserted into the case in a direction of the heating body and has a symmetric contour line based on a straight line a center of the fuel tank and the heating body. The ignition section is disposed at one of sides of the heating body based on the center. The hand warmer is portable, easy to use, and can be ignited without needing a separate external heat source."

Problems solved by technology

Hence, the fuel may be unnecessarily consumed, and preference of the user about the hand warmer is lowered.
Additionally, it is difficult for child, juvenile, etc. to have or treat the outside heat source such as the match or the lighter, and so the child and the juvenile may not use easily the hand warmer.

Abstract

A hand warmer ignites easily through simple handling, and extinguishes easily the ignition by using a simple method of converting a direction in which a fuel tank is inserted. As a result, fuel may not be unnecessarily consumed in the hand warmer. In addition, a user may trust the hand warmer and use easily the hand warmer

Description

TECHNICAL FIELD [0001]Example embodiments of the present invention relate to a hand warmer, more particularly relate to a portable hand warmer for generating heat by burning alcohol, gasoline, etc using a platinum ignition section and having size to be inserted into a pocket.BACKGROUND ART [0002]A common hand warmer for generating heat by burning fuel using a platinum ignition section injects the fuel therein, and ignites the platinum ignition section by using a lighter, a match, etc.[0003]Accordingly, operation of the hand warmer is not stopped until every fuel injected into the hand warmer is consumed after the platinum ignition section is ignited. In addition, an outside heat source such as the match or the lighter is necessarily required so as to ignite the platinum ignition section.[0004]In case that the hand warmer is not optionally turned on / off as mentioned above, the hand warmer may not be operated in accordance with willingness of a user. Hence, the fuel may be unnecessari...
