Abstract

The invention discloses a convenient plug type 3D printing spray head. The spray head comprises a shell, a nozzle, a heating device surrounding the outer wall of the nozzle, a fixed seat, a plastic introducing pipe and a metal terminal, wherein the fixed seat is provided with a through hole and is fixedly arranged in a cavity of the shell, and the plastic introducing pipe is arranged in the through hole of the fixed seat in a sleeving manner and is abutted with a through hole of the nozzle to form a consumable conveying cavity; a terminal clamping trough is formed in the fixed seat, and the metal terminal is fixedly arranged on the terminal clamping trough; a power supply wire of the heating device is connected to the metal terminal, and the metal terminal is in patch connection with a control circuit of 3D printing equipment; the melting point of the plastic introducing pipe is higher than that of a consumable. According to the convenient plug type 3D printing spray head, the problem that the consumable expands to block the pipe before being introduced into the through hole of the nozzle is solved; meanwhile, the metal terminal connected with the heating device is arranged in the clamping trough of the fixed seat, and the metal terminal is directly in the patch connection with a PCB (printed circuit board) of the control circuit of the printing equipment, so that the problems that a circuit connecting device is large in occupying space, is unstable and is easy to damage in inserting-plugging processes of the spray head are solved.

Description

technical field [0001] The invention relates to a 3D printing component, in particular to a 3D printing nozzle. Background technique [0002] In the past, 3D printing nozzles were integrated on 3D printers and drawing pens and could not be replaced, which limited the scope of use of 3D printing equipment. During the three-dimensional creation process of existing 3D printers and drawing pens, consumables of various colors and materials may be used according to the printing model set by the user. , the nozzles of 3D printers and drawing pens need to be replaced frequently to meet different requirements. [0003] Improvements have been made to address this problem in the industry. On the one hand, the detachable connection between the 3D printing nozzle and the printing equipment is realized in the mechanical structure. Separation is currently achieved by setting a pin-type power connector on the nozzle holder to connect with the control circuit on the 3D printing device, thu...
