Definitions

  • the present invention relates to a portable lighter, and more particularly to a battery powered flameless lighter. More specifically, the present invention relates to a rechargeable battery powered cigar lighter which includes a resistance heating element having a planar contact surface.
  • Most conventional battery powered portable lighters are designed for lighting cigarettes and mainly use double A or triple A batteries as their power source.
  • the batteries are housed in an enclosure and are connected in series in an electrical circuit to pass current through a resistance wire heating element to generate heat.
  • the wire heating element has a predetermined length dependent on the power source, and typically is wound into a tight spiral coil having an effective diameter sized to contact an abutting end of a cigarette.
  • Figure 1 illustrates a conventional wire heating element 500 having a first terminal connecting end 501, a second terminal connecting end 502, and an effective diameter D.
  • electrical current is passed through the wire heating element 500 from the first terminal connecting end 501 to the second terminal connecting end 502 to generate heat, and an abutting end of a cigarette is brought into contact with the heating element 500, which serves as an ignition source.
  • the lighter includes two AA penlight batteries housed in a hollow plastic housing. The batteries are connected to one another in series to provide current to a spirally- wound Nichrome wire heating element.
  • the lighter includes a pivotally mounted switch actuator to open and close a switch means to allow current to pass through the wire heating element to generate heat.
  • the heating element is positioned within a cavity formed in a sidewall of the housing in recessed relation to the sidewall to provide access to the wire heating element.
  • Battery powered lighters generally have not found widespread use or acceptance in the market place. This is because in comparison with gas lighters, in which fuel gas is ignited to generate a high temperature flame, the amount of energy at the resistance wire heating element is low, resulting in difficulties in igniting cigarettes and the like.
  • Difficulties in ignition are further compounded due to the fact that the abutting end of the cigarette or the like only make contact with a portion of the outer circumferential surface of the wire heating element, which results in a majority of the heat generated in the wire heating element being dissipated radially outwardly to the surrounding atmosphere.
  • the present invention provides 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.

  • the resistance current path comprises a spiral winding.
  • first terminal and the second terminal are longitudinally aligned in the plane at opposing sides of the heat generating body.
  • the first terminal, the second terminal and the heat generating body are integrally made.
  • the resistance heating element is formed from a single piece of sheet metal.
  • the sheet metal is selected from the group consisting of a nickel chromium based alloy and a tungsten based alloy.
  • the present invention provides a battery powered lighter comprising a battery, switch actuating means, and a switch to open and close the electric circuit, wherein the improvement resides in the lighter comprising a planar sheet- like resistance heating element, 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; and 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 said path, whereby a width of said contact surface in said plane is substantially greater then a thickness of the heat generating body
