Description
Technical field
The utility model is related to 3D printing field more particularly to a kind of ceramic heating heads of 3D printing pen.
Background technology
The ceramic heating header structure of the 3D printing pen of current producer each on the market is mainly by teflon pipe 1,2 and of heating wire
Ceramic mouth 3 forms, and as described in Figure 1, ceramic mouth 3 is made of afterbody 31, heating part 32 and stem 33, and 32 outer wall of heating part is set
There is external screw thread, heating wire 2 is by hand wound to external screw thread, and in teflon pipe insertion afterbody 31 and heated portion 32 is heated, outside
Screw thread plays the role of a positioning heating wire, and due to hand wound, inefficiency, low precision, while external screw thread also occupies
A part of wall thickness, is subject to the wall thickness of ceramic process to be limited so that and ceramic mouth heating part internal diameter is less than afterbody internal diameter, so as to cause
Teflon pipe is not fully inserted into heating part, heating wire is caused to heat teflon pipe incomplete so that in teflon pipe
Consumptive material be frequently occluded.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of ceramic heating head of 3D printing pen,
It can solve the problems, such as that teflon pipe heating is incomplete.
Technical solution is used by the utility model solves its technical problem：
A kind of ceramic heating head of 3D printing pen, including teflon pipe, heating wire and ceramic mouth, the ceramics mouth includes tail
Portion, heating part and stem, ceramic mouth are internally provided with the passage of conveying consumptive material, and the internal diameter of the afterbody is interior not less than heating part
Footpath, the internal diameter of heating part are more than stem internal diameter, and the teflon pipe outer diameter is not more than heating part internal diameter, and teflon pipe insertion tail
In portion and heating part, the heating part outer wall is curved surface, and the heating wire is sleeved on the outer wall of heating part.
As the improvement of above-mentioned technical proposal, the teflon pipe outer diameter is equal to afterbody internal diameter and heating part internal diameter.
As the improvement of above-mentioned technical proposal, the afterbody outer diameter is more than heating part outer diameter, and the two connecting place forms step
Face, described heating wire one end can prop up step surface.
As the improvement of above-mentioned technical proposal, the afterbody, heating part and stem are integrally formed.
The beneficial effects of the utility model have：
The external thread structure that the utility model passes through the ceramic mouth of cancellation so that teflon pipe is fully inserted into ceramic mouth
Inside, heating wire are sleeved on ceramic mouth so that heating wire is evenly heated the teflon pipe inside ceramic mouth, avoids Teflon
Putty inside pipe.
Description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein：
Fig. 1 is the product structure sectional view of the prior art；
Fig. 2 is the sectional view of the utility model embodiment.
Specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of ceramic heating head of 3D printing pen, including teflon pipe 1, heating wire 2 and ceramic mouth 3,
The ceramics mouth 3 includes afterbody 31, heating part 32 and stem 33, and ceramic mouth 3 is internally provided with the passage of conveying consumptive material, the afterbody
31 internal diameter is not less than the internal diameter of heating part 32, and the internal diameter of heating part 32 is more than 33 internal diameter of stem, and 1 outer diameter of teflon pipe is not
More than 32 internal diameter of heating part, and teflon pipe 1 is inserted into afterbody 31 and heating part 32, and 32 outer wall of heating part is curved surface, institute
Heating wire 2 is stated to be sleeved on 32 outer wall of heating part, in the present embodiment, 1 outer diameter of teflon pipe be equal to 31 internal diameter of afterbody and
32 internal diameter of heating part, teflon pipe 1 are inserted into heating part 32, and heating wire 2 is evenly heated the teflon pipe 1 inside ceramic mouth 3,
Avoid 1 inside putty of teflon pipe.
31 outer diameter of afterbody is more than 32 outer diameter of heating part, and the two connecting place forms step surface 34, described 2 one end of heating wire
Step surface 34 can be propped up, step surface 34 plays heating wire 2 position-limiting action, 33 one of the afterbody 31, heating part 32 and stem
Shaping.
Compared with prior art, heating wire 2 uses machine coiling in the utility model, then covers and be attached to ceramic 1 heating part of mouth
On 32, efficiency becomes higher, and precision is more preferable, and by 34 /V of step surface, external screw thread is not required to position, due to without external screw thread,
Without occupying wall thickness so that 32 internal diameter of heating part increases, and teflon pipe 1 may be inserted into heating part 32, and heating wire 2 is to Teflon
Pipe 1 is evenly heated, and 1 internal consumptive material of teflon pipe is avoided to block.
The better embodiment of the above, simply the utility model, but the utility model is not limited to above-mentioned reality
Example is applied, as long as it reaches the technique effect of the utility model with any same or similar means, should all belong to the utility model
Protection domain.
