Detailed description of the invention
In order to more clearly understand technology contents of the present utility model, describe in detail especially exemplified by following examples.
Referring to shown in Fig. 1, is the structural representation of the fan-free cooling device of the utility model 3D printer.
In one embodiment, this 3D printer fan-free cooling device, comprise air pump 2 and at least one air outlet 1, this air pump 2 is communicated with described air outlet 1 by pipeline 3, described air outlet 1 is tubulose, and this air outlet 1 is arranged at the position of extruding near shower nozzle 6 of described 3D printer.This 3D printer fan-free cooling device also comprises and connects and control the air pump control module 4 of air pump 2.
Wherein, as shown in Figure 2,3, 4, described air outlet 1 comprises the ventilation duct 11 and air outlet 12 that are interconnected, the upper end of described ventilation duct 11 is communicated with described air pump 2 by pipeline 3, the air outlet 12 described in the connection of lower end of described ventilation duct 11, described ventilation duct 11 is arranged at the described side of extruding shower nozzle 6, and described air outlet 12 is arranged near the described position of extruding below direction of extruding shower nozzle 6.This 3D printer fan-free cooling device can comprise plural air outlet 1, and as shown in figures 1 and 3, each air outlet 1 is communicated with described air pump 2 by multiple-pass joint 5, and the air outlet 12 of each air outlet 1 is uniformly distributed in the described position of extruding near shower nozzle 6.
In a preferred embodiment, as shown in Figure 2,3, this 3D printer fan-free cooling device comprises two air outlets 1, and the air outlet of two described air outlets 1 is symmetrically distributed in described extrudes shower nozzle 6 both sides.
In preferred embodiment, the extended line of the air outlet 12 of two described air outlets 1 intersects at described shower nozzle 6 of extruding and extrudes immediately below direction, and the angle of the extended line of the air outlet 12 of two air outlets 1 is 90 degree.
