Somatosensory 3D drawing pen

Abstract

The invention discloses a somatosensory 3D drawing pen comprising a pen shell, a pen tip connected to the end of the pen shell, and a control chip, wherein the pen shell is divided into a front end and a rear end, the pen tip comprises a heating nozzle, a forehearth is opened in the pen shell along its length, the exit end of the forehearth is connected to a feeding port of the heating nozzle, andthe 3D drawing pen also comprises a wire feeding mechanism, a motion sensor and a capacitive touch switch. The motion sensor includes acceleration control and angle control, and the acceleration control part can control the speed of a driving motor with the speed of a gesture. When the writing is accelerated, the speed of the driving motor can be increased, and the feeding speed of consumables can be increased to improve the writing fluency. On the contrary, when the writing speed slows down, the feeding speed of consumables can be reduced to avoid overly fast wire feeding speed, which causesoverflow. The angle control controls the drive motor to rotate forward and backward, and the capacitive touch switch is pressed and held to automatically unwind the wire when the pen tip faces up andhas an angle with the horizontal plane greater than 45 degrees.

Description

technical field [0001] The invention relates to the field of 3D drawing pens, in particular to a somatosensory 3D drawing pen. Background technique [0002] 3D drawing pens usually use plastic filament to write, and the built-in fan in the tip is used to cool the plastic filament. During operation, the user holds a pen to paint in the air, and the plastic wire in the pen barrel gushes out and solidifies rapidly under the action of the fan in the pen, thus forming a three-dimensional shape. [0003] At present, the 3D drawing pen has gradually become popular, but it still has the following problems: [0004] 1. Most of the existing 3D drawing pens are manually adjusted by buttons, which is extremely inconvenient during the creation process, and the speed of the wire output will not be intelligently adjusted according to the speed of gestures during creation, which results in uneven thickness of the finished product; [0005] 2. One of the existing 3D drawing pens’ threading...

Problems solved by technology

[0004] 1. Most of the existing 3D drawing pens are manually adjusted by buttons, which is extremely inconvenient during the creation process, and the speed of the wire output will not be intelligently adjusted according to the speed of gestures during creation, which results in uneven thickness of the finished product;

[0005] 2. One of the existing 3D drawing pens’ threading controls is press-type buttons to eject the thread. If you press it for a long time, your hands will be sore; the other is one-button threading. In time, the overflow material makes the work unsightly;

[0006] 3. The wire feeding mechanism of the existing 3D drawing pen mostly engages the plastic wire through gears, and the depth of the plastic wire is different during the gear rotation process. When the wire feeding resistance is large, the consumables are easy to be gnawed off
