Extrusion device of three-dimensional printer and cooling mechanism and cooling method thereof
First Claim
1. An extrusion device of a three-dimensional printer, comprising:
- a housing;
a nozzle connected with the housing;
a ratchet disposed in the housing;
an idler disposed adjacent to the ratchet, wherein a thermofusible material is jointly held by the ratchet and the idler and guided to be extruded through the nozzle; and
a cooling mechanism comprising an air pump and an air pipe, wherein the air pipe is partially disposed in the housing and is connected with the air pump,wherein the air pipe is configured for guiding the air extracted by the air pump to flow to the extrusion device, and an air vent of the air pipe is directly disposed toward the thermofusible material.

Abstract
An extrusion device of a three-dimensional printer comprises a housing, a nozzle, a ratchet, an idler and a cooling mechanism. The nozzle is connected with the housing, the ratchet is disposed in the housing, and the idler is disposed adjacent to the ratchet. A thermofusible material is jointly held by the ratchet and the idler, and is guided to be extruded through the nozzle. The cooling mechanism comprises an air pump and an air pipe. The air pipe is partially disposed in the housing and connected with the air pump for guiding the air extracted by the air pump to flow into the housing through the air pipe, thereby reducing an environment temperature inside the housing. Therefore, by disposing the air-guiding cooling mechanism, the advantages of enhancing the cooling effect and the printing quality are achieved.
