An improved hot melt glue gun with an automatic glue stick feeding structure

摘要

A hot-melt glue gun with an automatic glue stick Y feeding structure (2 figure 1) includes a housing (1 figure 1) that is gun-shaped and that includes an inlet (11 figure 1) and an outlet (12 figure 1). A glue stick feeding module is mounted in the housing and located adjacent to the inlet. The glue stick feeding module includes a motor 4 connected to a casing 22. The casing includes a passage P and a through-hole 27. The passage is located in the casing and intercommunicates with the inlet. The through-hole is aligned with the passage in a transverse direction. An activation module 3 includes an activation rod 31 reciprocatingly and movably extending through the through-hole. A micro-switch 4 is located adjacent to the activation module and is electrically connected to the motor. The micro-switch is configured to be pressed by the activation rod to activate the motor. By these means, the motor cannot operate in the absence of a glue stick interruptions of glue delivery cannot occur.
