Claims16
An electrically powered stripping tool for removing finish from a work surface, comprising:
- a tool body comprising a tool end, an opposing handle end comprising a handle, and a work surface side extending between the tool end and the opposing handle end,
- an air flow duct comprising an inlet end, an outlet end, and an internal cavity extending between the inlet end and the outlet end, the inlet end located at the tool end of the tool body facing the work surface side of the tool body, the outlet end extending out from the work surface side of the tool body,
- an electrical heating element located within the air flow duct internal cavity between the inlet end and the outlet end,
- an electrical fan located within the air flow duct internal cavity between the inlet end and the electrical heating element, the electrical fan configured to draw air into the inlet end of the air flow duct and direct it through the air flow duct internal cavity past the electrical heating element and out of the outlet end of the air flow duct,
- a heat sink comprising a rigid thermally conductive material attached to the tool end of the tool body such that a portion of the heat sink extends substantially into the internal cavity of the air flow duct at the inlet end of the air flow duct, and another portion extends out from the work surface side of the tool body,
- a scraper blade attached to and in thermal communication with the heat sink such that the scraper blade extends out from the heat sink to the work surface side of the tool body adjacent to the air flow duct outlet end, and
- a second handle located near the tool end of the tool body.
