Abstract
An air blowing tool comprises a connecting pipe (1) and an air blowing head (2). The air blowing head includes an inner wall (22), and an outer wall (21). An annular passage (24) is defined between the inner and outer walls. The inner wall encloses and forms a heating space (23) for placing a package (3) to be heated. A plurality of outlets (221) evenly defined in the inner wall. Each outlet is generally perpendicular to an adjoining portion of the annular passage, and generally perpendicular to an adjoining portion of the heating space.

A tool for blowing hot air onto heat-shrinkable packing material, the tool comprising:
- a connecting pipe adapted to be connected with a hot air blower;
- and
- an annular air blowing head comprising an outer wall, an inner wall, and an annular passage defined between the outer and inner walls and communicating with the connecting pipe, a circular heating space being defined inwardly from the inner wall and adapted for receiving a package having heat-shrinkable packing material, the head further comprising a plurality of outlets defined in the inner wall, each outlet communicating with the annular passage and with the heating space;
- wherein
- each outlet is generally perpendicular to an adjoining portion of the annular passage, and generally perpendicular to an adjoining portion of the heating space.
A hot air blowing tool, comprising:
- a pipe adapted for receiving hot air flow;
- and
- an air blowing head integrally formed with the pipe, the head comprising an outer wall, an inner wall and an air passage defined between the outer and inner walls and in communication with the pipe, a plurality of outlets being defined in the inner wall, each outlet communicating with the air passage and a space surrounded by the inner wall, each outlet being generally perpendicular to an adjoining portion of the air passage and generally perpendicular to an adjoining portion of the space surrounded by the inner wall.
In combination,
- a tool comprising:
- a connecting pipe adapted to be connected with a hot air blower;
- and
- an annular air blowing head comprising an outer wall, an inner wall, and an annular passage defined between the outer and inner walls and communicating with the connecting pipe, a circular heating space being defined inwardly from the inner wall, the head further comprising a plurality of outlets defined in the inner wall, each outlet communicating with the annular passage and with the heating space;
- a package having heat-shrinkable packing material and located around a center portion of the space;
- wherein
- each outlet is radially directed to a center of said space, and the pipe is directed generally along a tangent line with regard to the space toward the passage.
