Portable Rechargeable Battery Powered Flameless Cigar Lighter

Abstract

The present invention relates to a sheet like resistance heating element for a battery powered lighter. The heating element includes a first terminal for connecting the heating element to a first contact of an electrical circuit and a second terminal for connecting the heating element to a second contact of the electrical circuit. The heating element further includes a heat generating body arranged between the first terminal and the second terminal, the heat generating body providing an electrical current path between the first terminal and the second terminal, wherein the heat generating body comprises a planar contact surface along the path, whereby a width of said contact surface in the plane is substantially greater then a thickness of the heat generating body.

1 . A resistance heating element for a battery powered lighter, the heating element comprising:
 a first terminal for connecting the heating element to a first contact of an electrical circuit;   a second terminal for connecting the heating element to a second contact of the electrical circuit;   a heat generating body arranged between the first terminal and the second terminal, the heat generating body comprises an electrical resistance current path located between the first terminal and the second terminal for generating heat when current is applied between the first terminal and the second terminal, wherein the heat generating body comprises a planar contact surface along said path, whereby a width of said contact surface in said plane is substantially greater then a thickness of the heat generating body.   
     
     
         2 . The heating element according to  claim 1 , wherein the resistance current path comprises a spiral winding. 
     
     
         3 . The heating element according to  claim 1 , wherein the first terminal and the second terminal are longitudinally aligned in said plane at opposing sides of the heat generating body. 
     
     
         4 . The heating element according to  claim 1 , wherein the first terminal, the second terminal and the heat generating body are integrally made. 
     
     
         5 . The heating element according to  claim 1 , wherein the resistance heating element is formed from a single piece of sheet metal. 
     
     
         6 . The heating element according to  claim 1 , wherein the sheet metal is selected from the group consisting of a nickel chromium based alloy and a tungsten based alloy.
