Abstract
A heating system for a hand-held glue gun has a low-mass melting chamber, high-power resistance heating element, and thermostat (24). The heating element is arranged between the chamber and thermostat (24), so that the thermostat's (24) response to the heating element mirrors that of the load in the chamber.
Claims15
A heating system comprising a melting chamber having low thermal inertia, a heating element having one side in thermal contact with said chamber and providing energy to said melting chamber at a rate of at least about 10 watts per gram weight of said melting chamber, and a thermostat in direct thermal contact with an opposite side of said heating element.
A heating system for a hand-held glue gun comprising a metal tube having a cavity for receiving solid glue to be melted, an electrically insulating, thermally conducting film mounted on an exterior surface of said tube, a resistance heating wire coil mounted on an exterior surface of said film such that one side of said coil is in thermal contact with said tube and providing energy to said melting chamber at a rate of at least about 10 watts per gram weight of said melting chamber, and a thermostat mounted on an opposite side of said coil to absorb heat directly from said coil.
