CN204217147U - A kind of electrothermal tube - Google Patents

Abstract

The utility model discloses a kind of electrothermal tube.The purpose of this utility model is the electrothermal tube providing a kind of improvement.The utility model comprises main body, described main body comprises heating section and is located at the power connector end at heating section two ends, it is characterized in that: described heating section is spiral, the number of turns of spiraling of described heating section is greater than a circle, increase contact-making surface by the heating section of multi-turn, reduce the caloric value of individual pen, make heat more even, also be not easy because local overheating is burnt, have that structure is simple, with low cost, the feature of durable.

Description

A kind of electrothermal tube

Technical field

The utility model relates to a kind of electrothermal tube, particularly relates to a kind of electrothermal tube.

Background technology

Current heat-generating pipe normally adopts circular arc, linear, individual pen shape, and the contact-making surface that this several heat-generating pipe all exists between heated body is very few, and firing rate is slower; Under identical power, heat-generating pipe is shorter, and local pyrexia amount is comparatively large, easily burns because local pyrexia amount is excessive.

Utility model content

Technical problem to be solved in the utility model to provide a kind of electrothermal tube, and it can efficiently solve, and firing rate is comparatively slow, the problem of local overheating, has that structure is simple, with low cost, the feature of durable.

For achieving the above object, the technical solution adopted in the utility model is: a kind of electrothermal tube, comprises main body, and described main body comprises heating section and is located at the power connector end at heating section two ends, it is characterized in that: described heating section is spiral, the number of turns of spiraling of described heating section is greater than a circle;

Further, described heating section spiral circle downside be in same level line.

The utility model have employed above-mentioned technical scheme, overcomes the deficiency of background technology, provides a kind of electrothermal tube, and it can efficiently solve, and firing rate is comparatively slow, the problem of local overheating, has that structure is simple, with low cost, the feature of durable.

Accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present utility model

In figure: main body 1, heating section 11, power connector end 12.

Embodiment

Below in conjunction with accompanying drawing, by being further described embodiment of the present utility model, make the technical solution of the utility model and beneficial effect thereof clearly, clearly.

See accompanying drawing 1, the utility model comprises main body 1, and described main body 1 comprises heating section 11 and is located at the power connector end 12 at heating section 11 two ends, it is characterized in that: described heating section 11 is spiral, and the number of turns of spiraling of described heating section 11 is greater than a circle;

Further, described heating section 11 spiral circle downside be in same level line.

Because the number of turns of spiraling of section 11 of generating heat is greater than a circle, and the section of heating 11 is spiraled, the downside of circle is in same level line, and in this case, heating section 11 just increases greatly with the contact-making surface of heated body, and being heated can relatively evenly fast; Meanwhile, the local electrical resistance of heating section 11 is less, and local pyrexia amount is also less.

By the description of above-mentioned structure and principle; person of ordinary skill in the field is to be understood that; the utility model is not limited to above-mentioned embodiment; the utility model basis adopts the improvement of techniques well known and substitutes and all drop on protection range of the present utility model, should be limited by each claim.

Claims (2)

1. an electrothermal tube, comprises main body, and described main body comprises heating section and is located at the power connector end at heating section two ends, and it is characterized in that: described heating section is spiral, the number of turns of spiraling of described heating section is greater than a circle.

2. a kind of electrothermal tube according to claim 1, is characterized in that: described heating section spiral circle downside be in same level line.
