Abstract

The present invention provides an air duster structure configured to eject compressed air from a nozzle, including a flow adjustment mechanism configured to adjust the amount of air ejected from the nozzle, and a driving tool. The flow regulating mechanism includes: a pipe for circulating air; a valve member provided in the pipe and movable; and a throttle configured to gradually change a flow in which the air circulates as the valve member moves The area of ​​the channel to control the flow of air in the line. The restriction is structured to increase the area of ​​the flow passage at an accelerated rate when the valve member moves in a direction to open the conduit.

Description

technical field [0001] The present invention relates to an air duster structure that ejects air from a nozzle by using externally supplied compressed air, and to a driving tool provided with the air duster structure. Background technique [0002] In order to blow away fine wood chips and the like before nailing, an air duster gun or an air duster included in the driving tool has been used. For example, JP-A-H10-109280 discloses a driving tool including an air duster. The related art disclosed in JP-A-H10-109280 is structured such that air is ejected from a nozzle by pushing in an operation button that opens and closes a release valve. [0003] In order to adjust the amount of air sprayed from the nozzle according to the amount of operation of the operation button in the air cleaner as described above, it is considered to form the release valve or the pipe into a tapered shape to increase the flow of air according to the amount of pressing of the operation button The area o...
