Abstract

A thermally enhanced shaving device is provided including a hot air supply, a blade, a housing on which the blade is mounted, and an elongated handle to which the housing is attached. The housing has a continuous hot air passageway through it which has an exit and an entrance. The blade is mounted across the exit of the passageway, while the handle has an internal channel which is connected to the entrance of the hot air passageway. The hot air supply includes a heating filament and fan which can be positioned either within the channel or remote thereto. In any case, the hot air supply, the channel, and the air passageway are all in fluid communication with one another. The device is operated by blowing ambient air across the hot filament using the fan such that the channel directs the resulting hot air through the passageway, past the blade, and onto the surface to be shaven immediately ahead of the blade's shaving path.

Dependent claims

A method for shaving hair from a body surface comprising the steps of:

providing a thermally assisted shaving device having a heat source, a blade, a blade housing on which said blade is mounted, and a handle to which said housing is attached, wherein said housing is formed with a hot air passageway therethrough having an exit and an entrance and said blade is mounted in said exit, further wherein said handle has a channel internal thereto connected to said entrance, and said heat source includes a heating filament and a fan in fluid communication with said channel;
heating said filament to an elevated temperature exceeding ambient temperature;
blowing ambient air across said hot filament with said fan to heat said ambient air to hot air;
positioning said device such that said housing abuts said body surface, wherein said exit and blade are juxtaposed with said body surface;
directing said hot air through said channel, into said air passageway, past said blade, out said exit, and onto said body surface ahead of a shaving path for said blade;
heating said hair on said body surface with said hot air;
and
shaving said heated hair from said body surface with said blade by sliding said blade housing across said body surface, wherein said blade follows said shaving path.
