Abstract
The utility model provides a special-shaped lamp filament infrared lamp tube. The special-shaped lamp filament infrared lamp tube is composed of lamp pins, a lamp tube holder, a lamp tube shell and a special-shaped lamp filament; the special-shaped lamp filament is of a spiral structure; the thread pitch of the special-shaped lamp filament is decreased gradually from one end to the other end; the diameter of the special-shaped lamp filament is increased gradually from one end to the other end; and the cross section of the lamp filament is hexagon-shaped. According to the special-shaped lamp filament infrared lamp tube of the utility model, the diameter-varying thread pitch- varying lamp filament is adopted, such that heating temperature of the infrared lamp tube is in gradient distribution, and therefore, a paint can be decomposed and overflow periodically, and as a result, a coating layer can have excellent structural and physical-chemical properties.
Description
Technical field
The utility model relates to the light technical field of heating, specifically refers to a kind of special-shaped filament infrared lamp.
Background technology
Normally used infrared heating fluorescent tube is uniform pitch equal diameter structure, add temperature constant on hot path whole, this does not have any problem when the heating large device, but during for the heating small parts, particularly surface scribbles the small size part of coating, constant heating-up temperature can not meet the decomposition curve of coating itself, tend in the inner number of drawbacks that produces of coating, if this problem of multicomponent coating can be more serious, no matter dry the coating obtained like this, be that Mechanics of Machinery index or physicochemical properties are certain to exist serious problems.
The utility model content
For addressing the above problem, the utility model provides a kind of special-shaped filament infrared lamp.
Concrete solution is: a kind of special-shaped filament infrared lamp, it is comprised of lamp base, tube face, tube shell and special-shaped filament, described special-shaped filament is helical structure, and its pitch from one end to the other side reduces gradually, and diameter from one end to the other side increases gradually.
Further, the special-shaped filament cross section is regular hexagon.
The utility model adopts the special-shaped filament of variable-diameter variable-pitch, makes the heating-up temperature distribution gradient of infrared lamp, coating is overflowed interim the decomposition, and then guarantee that coating has good structure, physico-chemical property.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The structural representation that Fig. 2 is special-shaped filament.
Wherein:
1. lamp base 2. tube face 3. tube shell 4. special-shaped filaments
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of special-shaped filament infrared lamp, it is comprised of lamp base 1, tube face 2, tube shell 3 and special-shaped filament 4, described special-shaped filament 4 is helical structure, its pitch from one end to the other side reduces gradually, diameter from one end to the other side increases gradually, and special-shaped filament 4 cross sections are regular hexagon.
The utility model adopts the special-shaped filament 4 of variable-diameter variable-pitch, makes the heating-up temperature distribution gradient of infrared lamp, coating is overflowed interim the decomposition, and then guarantee that coating has good structure, physico-chemical property.
