Fig. 2 is overall schematic elevation view of the present utility model.
Fig. 3 is overall A-A schematic cross-sectional views of the present utility model.
Embodiment
With reference to the accompanying drawings and with reference to Examples detail the utility model.
As shown in Figure 1：A kind of three enter the printhead of a colored 3D printer out, including three structure identicals first dissipate
Heat pipe 3, the second radiating tube 8 and the 3rd radiating tube 12, described three tapered arrangements of radiating tube, three radiating tube upper ends are set
There is fan base 1, lower end is provided with taper hybrid chamber 5, and nozzle 6, the bottom of fan base 1 are provided with the bottom of taper hybrid chamber 5
Fan 18 is provided with, heating rod 16 is provided with described taper hybrid chamber 5, deep bead 10 is provided with above heating rod 16,
Described fan 18, deep bead 10 and heating rod 16 is located at the same vertical center of device.
Pass through big connector 1, big connector 29 and big connector 3 13 between described radiating tube and fan base 1
It is connected.Connector plays a part of fixed radiating tube, while provides fixed position to fan 18.
Described radiating tube is fixed with taper hybrid chamber 5 by internal thread.
Described nozzle 6 is fixed on the bottom of taper hybrid chamber 5 by internal thread, and nozzle 6 and taper hybrid chamber 5 are detachable
Structure.The thickness of discharging can be changed by changing the nozzle 6 of different pore size, change printing precision indirectly.
Connected between described radiating tube and deep bead 10 by small connector 1, small connector 27 and small connector 3 11
Connect fixation.The position of radiating tube is determined by the male-pipe of the protrusion on taper hybrid chamber, while radiating tube and deep bead 10 are logical
Too small connector is connected, and deep bead 10 plays fixation to radiating tube, while avoids fan 18 directly to heating rod 16
Radiated with taper hybrid chamber 5.
Described radiating tube is internally provided with vertical trunnion 14, and trunnion 14 is connected with taper hybrid chamber 5.
Thermistor (temperature) sensor is installed on prominent joint on described taper hybrid chamber 5, thermistor (temperature) sensor
