Abstract
An air blowing tool includes 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 defines a heating space (23) for accommodating a package (3) to be heated. A plurality of evenly distributed outlets (221) is defined in the inner wall. Each outlet is defined at an acute angle relative to the annular passage.
Claims12
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 defined at an acute angle relative to the annular passage of the head such that a direction of air flow in the outlet is generally in compatible alignment with a direction of circulating air flow within the annular passage.
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 oriented at an acute angle relative to the air passage.
In combination,
- 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;
- and
- a package having heat-shrinkable packing material and located around a center of the space;
- wherein
- each outlet is defined at an acute angle relative to the annular passage of the head such that a direction of air flow in the outlet is generally compatible with a direction of circulating air flow within the annular passage to guidably grasp said circulation air flow into the outlet and result in turbulence in the space.
