Abstract
The utility model discloses a 3D drawing pen. The 3D drawing pen consists of a pen head and a shell thereof, wherein a bracket is fixed on the inner wall of the shell of the pen head; the hollow part of the bracket is provided with a through hole for outputting drawing materials; a ring-shaped electric-heating device is fixed on the outer wall of the bracket; a plugging part for a power supply of the ring-shaped electric-heating device is fixed at the upper end of the bracket; the ring-shaped electric-heating device is connected with a pen body by the plugging part via a circuit manner. The 3D drawing pen disclosed by the utility model has the beneficial effects that due to adoption of the split type structure of the pen body and the pen head, if a part is damaged, the damaged part can be replaced, and the whole replacement is not needed, so that the cost of a user can be reduced; when a heating structure is damaged, the user unplugs the pen head directly, the plugging part of the pen head is disconnected, and then the pen head can be replaced, so that maintenance is convenient for the user and the purpose of the 3D drawing pen is achieved.
Description
Technical field
The utility model relates to a kind of drawing pen of the 3D of having printing function, is a kind of 3D drawing pen specifically.
Background technology
The nib of common drawing pen and a body are all overall structures, and drawing pen to hold flimsy position be most exactly nib and heater thereof, after this just causes the parts damages in nib, non-specialized-technical personnel are difficult to maintenance.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of 3D drawing pen that can be safeguarded voluntarily by user heater.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of 3D drawing pen, formed by nib and shell thereof, the outer casing inner wall of described nib is fixed with support, in support, have the through hole of output drawing materials in vain, the outer wall of support is fixed with annular electro thermal device, and the upper end of support is fixed with the connector of annular electro thermal device power supply, and annular electro thermal device is connected with a body circuit by connector.
Further, described support is also connected with the temperature probe of temperature control circuit.
In the utility model, described annular electro thermal device refers to the heating wire that is looped around support.In the utility model, described annular electro thermal device refers to the metal film resistor that support outer wall forms through etching.In the utility model, described annular electro thermal device refers to the PTC pottery that middle part is free.
Further, on described support and on the top of heater, be provided with fin.Do like this fan assembly that can save in existing 3D drawing pen, can greatly alleviate the weight and the diameter that dwindles pen of pen, can also abate the noise, strengthen the stability of pen.
Further, also comprise nozzle, one end of described nozzle communicates with the through hole on described support, and the other end of nozzle stretches out through after nib.
Further, between described written inwall and annular electro thermal device, be also provided with thermal insulation layer.
In the utility model, described nozzle is non-metallic material.Preferably, described nozzle is pottery or polytetrafluoroethylene (PTFE) material.Can effectively prevent the generation of scalding.
On the shell of described nib, be provided with upper connector, be provided with the lower connector suitable with upper connector with it at described pen.
The beneficial effects of the utility model are: owing to having adopted a body and written split-type structural, damage replaceable damage parts if any part, without integral replacing, thereby can reduce user's cost.In the time that heating arrangement damages, user directly pulls up nib, disconnects written connector, just can change nib, has facilitated user's maintenance, thereby has realized the purpose of this utility model.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
