Problems solved by technology
[0002] In the field of 3D printing, when the nib of the printing pen is producing filament (glue), the preheating interval of the glue is short. When the commonly used 5V power supply is used, the heating efficiency is not high, the nib cannot feed the wire quickly, and it is easy to plug.
Moreover, the ceramic heating head of the heating head is exposed, and the high temperature is easy to burn the user

Abstract
The invention discloses a 3D printing pen. The 3D printing pen comprises a heating head, a fixing seat, a circuit board and a pen cap. The heating head is provided with a feeding port, a discharging port and a discharging channel; and the feeding port and the discharging port both communicate with the discharging channel; the feeding port is used for communicating with a feeding device; and the length of the discharging channel is 15-30 mm. A clamping groove is formed in the fixing seat, and one end, with the feeding port, of the heating head is installed in the clamping groove in a clamped mode to enable the heating head to be in connection with the fixing seat. The circuit board is connected with the fixing seat and is electrically connected with the heating head through a connecting wire. The pen cap comprises a shell body and heating insulation strips; the shell body is provided with an accommodating cavity, a first opening and a second opening; the first opening and the second opening both communicate with the accommodating cavity; the heating head is installed in the accommodating cavity; the end of the heating head penetrates out of the second opening and protrudes out of the shell body; and of the multiple heat insulation strips are installed in the inner wall of the accommodating cavity, so that intervals are reserved between the outer wall of the heating head and the inner wall of the accommodating cavity. The 3D printing pen is not prone to being blocked in the head and hurting a user.
Description
technical field [0001] The invention relates to the field of 3D printing, in particular to a 3D printing pen. Background technique [0002] In the field of 3D printing, when the nib of the printing pen is feeding the filament (glue), the preheating interval of the glue is short. When the commonly used 5V power supply is used, the heating efficiency is not high, the nib cannot feed the wire quickly, and it is easy to plug. Moreover, the ceramic heating head of the heating head is exposed, and the high temperature is easy to burn the user. Contents of the invention [0003] Based on this, it is necessary to provide a 3D printing pen that is not prone to clogging and scalding the user. [0004] A 3D printing pen, comprising: [0005] A heating head, the heating head has a feed port, a feed port and a discharge channel, the feed port and the discharge port are all connected to the discharge channel, and the feed port is used to communicate with the feed The device is connec...
