Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples.

Embodiment

The device electronic heater welding structure that adjusts the temperature electronically as shown in Figure 1, 2, including ceramic tube 8,8 length ratio of ceramic tube Short in the past, 8 outer wall of ceramic tube winds heating wire 9, is equipped with two adjacent hole a7 and hole b10 in ceramic tube 8 from top to bottom, adjacent Hole setting is used for code wire 2, and the hole bottom a7 can lead to, and wire stylet 1 does not pass to bottom, the perforation of the hole bottom b10, wire stylet 1 stretches out from the hole bottom b10, and it is pad at the a7 top exit of hole, the hole bottom b10 goes out that hole a7 and hole b10, which are equipped with wire stylet 1, It is pad at mouth, pad is that wire stylet 1 and heating wire 9 pass through winding carry out face and face welding, that is, wire stylet 1 and hair Heated filament 9 is welded by being closely wound heating wire 9 to progress face on wire stylet 1 and face, and it is meticulous to change originally soldered material (0.15mm) causes Product jointing success rate too low, and product is unable to reach batch production purpose, the spacing of heating wire 9 and silk Greatly, it is effectively prevented silk and mutually touching for silk causes partial short-circuit, wire stylet 1 is arranged at 2 center of conducting wire, that is, conducting wire The outer surface cover of core 1 is conducting wire 2, and conducting wire 2 is Teflon material, Teflon alias: polytetrafluoroethylene (PTFE) (Poly tetra Fluoroethylene is abbreviated as PTFE), present integrated wire, present wire stylet and conducting wire wall be it is integrated, product is more steady Gu high temperature resistant and insulation effect are more preferable.

As shown in figure 3, being handled on the outside of the pad and heating wire by pre insulated, that is, wrapped up with insulant 6, warp It is not easily to fall off to cross pre insulated processing insulant, then external setting insulant 6, two layers of insulation, safety is good, and insulant 6 is patent High temperature insulating material in number ZL2013107476175.

In use, electronic heater further includes sheath 5, about 5 sheath is hollow, and sealed bottom connects cold extrusion end socket, uses Argon arc welding process repair welding, so that stronger and sealing, thoroughly guarantees sealing without gas leak phenomenon, lower part is provided with pottery in sheath 5 Porcelain tube 8, ceramic tube 8 and conducting wire 2 are located at center, insulant 6 are equipped between ceramic tube 8 and conducting wire 2 and sheath 5, on sheath 5 Portion's outer wall is equipped with lid 4, and lid 4 is incorporated 5 specified position of sheath, and the particular location point for needing to press can be set by tooling, oblique right Locating slot carries out surrounding extruding, and locating slot inside length is greater than length of outer side, is fixed on lid 4 on sheath 5, lid 4 and sheath 5 are adopted Cooperated with pine with mode, after product is fixed by tooling, is squeezed lid 4 to sheath with skew force, product advantage is zero Component processing required precision reduces, and processing cost reduces；It is smaller to product product external force when assembling product, guard head (installation Position), any deformation will not be generated, qualification rate is promoted, and working efficiency is promoted, so that product cost is reduced, materials diameter 12mm The round steel of long 24mm, the hollow pipe of outer diameter 4mm internal diameter 3mm long 100mm, conventionally employed diameter 12mm long 100mm round steel, than this production Product materials are 6 times more, and in addition tradition needs multiple vehicle outer diameter and repeatedly drilling, and concentricity is difficult to control, and this product uses cold-extruded briquetting Head technology is riveted into one, not only simple process and quality is guaranteed, is not integrally formed, still without drilling with the conjunction of lid 4 It is entirely capable of reaching the pressure of design requirement after riveting, processing cost is decreased obviously, and the lid 4 is in inverted T shaped, and lid 4 is hollow, 4 ring of lid Recess is equipped with locating slot on shape connector, and positioning slot cross-section is triangular in shape, and 4 external wall of upper portion of lid is recessed inwardly, and recess can apply External force, the external force that is not recessed can not apply, lid 4 from 5 bottom of sheath put into, after be directly placed into tooling, lid 4 can arrive the position preset It sets, there is conducting wire 2 above, difficult dress can be compared, 4 inner hole of lid obtains the upper limit of roughness Ra using the method for remove materials Value is 0.8 μm, and 4 bottom of lid use the upper limit value of the method acquisition roughness Ra of remove materials for 0.8 μm, 5 outer diameter of sheath The method for using remove materials obtains the upper limit value of roughness Ra for 0.4 μm, so that more stable when the riveting of product lid 4 With it is effective, flushed at the top of 3 top of the sealant and sheath 5, sealant 3 exposing outside it is few, it is few by oxidation, but being above can also It uses, 1 positive and negative anodes of wire stylet are first separately connected ceramic tube 8, and wire stylet 1 provides control signal and powers on, operating path are as follows: Power positive line → ceramic tube → insulant → heating wire → insulant → ceramic tube → power cathode line.

It should be understood that the above is only the preferred embodiment of the utility model only, it is not sufficient to limit this reality It for those of ordinary skills, can basis within the spirit and principle of utility model with novel technical solution Above description is increased and decreased, is replaced, converted or is improved, and all these increases and decreases, replacement, transformation or improved technical solution, It all should belong to the protection scope of the appended claims for the utility model.
