Background
3D print pen is free scribble for hand-held type 3D and makes drawing pen, and the consumptive material that needs for drawing because of 3D print pen scribbles is plastics wire rods such as solid PLA, ABS, and the wire rod needs heat to 180 ℃ and melts, then extrusion moulding makes the drawing, so the temperature can concentrate on the nib, to handheld drawing, forms safety problems such as scald easily. Therefore, the invention of the novel heat-preservation scald-proof nozzle of the 3D printing pen is very necessary.
Disclosure of Invention
The invention provides a novel heat-preservation scald-proof nozzle of a 3D printing pen, and aims to solve the problems that the existing 3D printing pen is easy to scald and poor in safety.
In order to achieve the technical purpose and achieve the technical effect, the invention is realized by the following technical scheme: a novel heat-preservation and scald-proof nozzle for a 3D printing pen comprises a ceramic sprayer, wherein heating resistance wires are uniformly wound on the outer side of the ceramic sprayer, thermistors are covered on the surfaces of the heating resistance wires, and the thermistors and the heating resistance wires are respectively led out to be connected to plug-in terminals; the ceramic nozzle is connected with the connecting piece through a long pipe at the tail part, and the front end of the ceramic nozzle is sleeved with a heat insulation gasket; the ceramic sprayer is characterized in that an inner shell is sleeved outside the ceramic sprayer, and an outer shell is sleeved outside the inner shell.
Preferably, a gap of 1-2mm is reserved between the outer shell and the inner shell, and the double-layer nozzle has an anti-scald function.
Preferably, a plurality of strip-shaped heat dissipation holes are uniformly distributed in the outer contour of the shell, so that the shell can dissipate heat better.
Preferably, the long pipe is a tetrafluoride pipe; the heat conduction of the tetrafluoride tube is slow.
Preferably, the heat insulating gasket of the present invention is made of teflon.
Preferably, the thermistor of the present invention is fixed to the surface of the heating resistance wire by a high temperature resistant tape.
Preferably, the shell and the connecting piece of the invention adopt a clamping structure.
The invention has the advantages that the gap is arranged between the inner shell and the outer shell, and the heat of the inner shell is preserved while the heat transfer to the outer shell is reduced; the front and the back of the ceramic nozzle are respectively provided with the tetrafluoride pipe and the heat insulation gasket, so that the rapid heat transfer can be avoided, and the purposes of heat preservation and scald prevention are achieved; the invention has relatively independent structure, the shell adopts a clamping structure for fastening connection, the assembly is simple, and the disassembly and the replacement are convenient.

Fig. 2 is a cross-sectional view of the overall structure of the present invention.
In the figure: 1-outer shell, 2-inner shell, 3-ceramic nozzle, 4-heat-insulating washer, 5-thermistor, 6-heating resistance wire, 7-plug terminal, 8-long tube, 9-connecting piece.
Detailed Description
The invention is further described below with reference to the accompanying drawings: as shown in fig. 1 and 2, the novel heat-preservation and anti-scald nozzle for the 3D printing pen comprises an outer shell 1, an inner shell 2, a ceramic spray head 3, a heat-insulation washer 4, a thermistor 5, a heating resistance wire 6, a plug-in terminal head 7, a long tube 8 and a connecting piece 9; the heating resistance wire 6 evenly winds on the ceramic nozzle 3, the thermistor 5 is fixed on the surface of the heating resistance wire 6 by utilizing a high-temperature resistant adhesive tape, the thermistor 5 and the heating resistance wire 6 are respectively led out to be connected to the plug-in terminal head 7, the front end of the ceramic nozzle 3 is fixedly connected with the heat insulation gasket 4, the ceramic nozzle 3 is connected with the connecting piece 9 through the long tube 8 at the tail part, the inner shell 2 and the outer shell 1 are sequentially sleeved on the outer surface of the ceramic nozzle 3, and a clamping type structure is adopted between the outer shell 1 and the connecting piece 9.
Wherein a gap of 1-2mm is left between the outer shell 1 and the inner shell 2; a plurality of strip-shaped heat dissipation holes are uniformly distributed on the outer contour of the shell 1; the heat insulation gasket 4 is made of a teflon material; the long pipe 8 is a tetrafluoride pipe; a plurality of claws at the upper end of the shell 1 are clamped in the inner hole of the connecting piece 9.
In the concrete implementation, there is 1-2 mm's interval between shell 1 and the inner shell 2, be similar to the interior outer shell structure of thermos cup, the air is as heat-conducting medium in this interval, it is low than interior outer shell ABS's heat transfer efficiency, both reduced the interior heater strip of inner shell 2 and add the thermal speed that the heat transfer came out, keep the difficult reduction of temperature in the inner shell 2, play the heat preservation effect, let the difficult quick rise of temperature of shell 1 simultaneously, when the heat that the inner shell 2 transfer came out was lost the air by shell 1 fast, so the temperature of shell 1 will obviously reduce, thereby reach the purpose of preventing scalding. Besides the double-layer heat-preservation and anti-scald structure, the structure also adopts a non-contact design for avoiding direct solid heat transfer of a heating part, the non-contact design is that a heat-insulation gasket 4 with slow heat conduction is arranged at the front end of the ceramic nozzle 3, and a tetrafluoride pipe with slow heat conduction is arranged at the tail end of the ceramic nozzle, so that the structure can avoid the rapid heat transfer, thereby achieving the purposes of heat preservation and scald prevention; the heat dissipation holes in the shape of long strips are also designed on the shell 1, so that the heat is guaranteed to be timely transmitted out, and the anti-scalding effect is achieved. Meanwhile, the structure of the whole nozzle is relatively independent, and the shell 1 and the connecting piece 9 are in a clamping structure, so that the nozzle is simple to assemble and convenient to disassemble and replace.
The technical solutions of the present invention or similar technical solutions designed by those skilled in the art based on the teachings of the technical solutions of the present invention are all within the scope of the present invention.
