Abstract: The disclosure relates to a spray gun, and particularly relates to a suction pipe rotating device, and a spray gun with same. The device includes: a rotary knob rotatably arranged at a top of a gun body of the spray gun; a rotary connecting portion, where one end of the rotary connecting portion is arranged on the rotary knob and is movably inserted into a material suction hole of the spray gun; and an angle suction pipe including a straight pipe and an inclined pipe that are connected to each other, where the straight pipe is rotatably arranged in the material suction hole and is connected to the other end of the rotary connecting portion, the inclined pipe is obliquely arranged, and an end of the inclined pipe is close to a joint between a side wall and a bottom of a material barrel of the spray gun.

Abstract: The invention relates to a heating device for a hot melt glue gun, comprising a tip and a heating piece; the tip comprises a connecting portion, a tapered heating portion and a glue output portion which are connected in turn; the inner cavities of the connecting portion, the tapered heating portion and the glue output portion communicate with one another in turn; at least one straight wall parallel to the axis of the tapered heating portion is disposed on the outer wall of the tapered heating portion, and the inner wall of the heating piece fits tightly with the straight wall; the heating device for a hot melt glue gun has a rational structure and high accuracy, is conveniently assembled and tightly fitted, accelerates the melting of the glue rod, and enhances the utilization efficiency of the hot melt glue gun.
