Embodiment 1

[0016] Embodiment 1: as figure 1 and figure 2 As shown, a 3D drawing pen includes a pen tip 4 and a pen body 8 detachably connected to the pen tip 4. The pen tip 4 includes a shell, and a bracket 1 is fixed in the shell of the pen tip, and the bracket 1 is hollowed out with a through hole for outputting drawing materials. , the outer wall of support 1 is provided with annular electric heating device 2, and the upper end of support 1 is provided with the connector 5 that conducts power with annular electric heating device 2, and annular electric heating device 2 is connected with pen body 8 circuits by connector 5. A cooling fin 6 is arranged on the support 1 and on the upper part of the annular electric heating element 2 . One end of the nozzle 7 communicates with the through hole on the support 1, and the other end of the nozzle 7 protrudes through the nib 4. A heat insulation layer is also provided between the inner wall of the nib 4 and the annular electric heating devic...

Embodiment 2

[0019] Embodiment 2: It is basically the same as Embodiment 1, except that: the annular electric heating device 2 refers to a metal film resistor formed by etching the outer wall of the bracket 1 .

Embodiment 3

[0020] Embodiment 3: It is basically the same as Embodiment 1, except that: the ring-shaped electric heating device 2 refers to the PTC ceramic with a hollow in the middle.

Abstract

The invention discloses a 3D (three-dimensional) drawing pen which is composed of a nib and a shell thereof, wherein a bracket is fixed on the inner wall of the shell of the nib, and the bracket is hollow and has a through hole through which drawing materials are outputted, an annular electric heating device is fixed on the outer wall of the bracket, a connector for a power supply of the annular electric heating device is fixed at the upper end of the bracket, and the annular electric heating device is in circuit connection with the nib through the connector. The 3D drawing pen disclosed by the invention has the beneficial effects that because a pen body and the nib are formed into a split structure, if part of the pen is damaged, damaged parts can be replaced, and integral replacement is not required, therefore, the cost of users can be reduced. When a heating structure is damaged, a user directly unplugs the nib, and disconnects the connector of the nib, so that the nib can be replaced, and the user maintenance is facilitated, thereby achieving the purpose of the invention.

Description

technical field [0001] The invention relates to a drawing pen with 3D printing function, in particular to a 3D drawing pen. Background technique [0002] The nib and pen body of common drawing pens are integral structures, and the most easily damaged parts of drawing pens are the nib and its heating components, which makes it difficult for non-professional technicians to repair the damaged parts in the nib. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a 3D drawing pen that can maintain the heating member by the user. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a 3D drawing pen, which is composed of a pen head and its shell, the inner wall of the shell of the pen head is fixed with a bracket, the bracket is hollow with a through hole for outputting drawing materials, and the outer wall of the brack...
