Electric heat pen with sandwiched heater element

An electric heat pen comprising:

• a pen base adapted to be held in the hand of a user, said pen base having a longitudinal axis;
• a pen head fastened to one end of said pen base and defining a receiving chamber;
• an electric heating element mounted inside the receiving chamber of said pen head and electrically connected to produce heat;
• an upper conductor and a lower conductor respectively disposed in contact with said electric heating element, said electric heating element being actuated to produce heat when said upper conductor and said lower conductor are respectively connected to two opposite terminals of power supply;
• and
• a hot plate that covers said receiving chamber of said pen head and that is heated by said electric heating element, said hot plate forming a non-zero angle with said longitudinal axis of said pen base;
• wherein said receiving chamber of said pen head is covered with a top cover, and a spring plate is mounted inside said receiving chamber, and attached to said top cover to impart a downward pressure to said upper conductor against said electric heating element and said lower conductor;
• and
• wherein a steel plate is sandwiched in between said spring plate and said upper conductor, and an electrically insulative heat resisting film is sandwiched in between said upper conductor and said steel plate.
