Description

Technical Field

[0002] Single-helix filaments can increase brightness, distribute heat evenly, extend life, and make better use of the space inside the bulb. The spiral shape can make the filament relatively long while remaining within the limited space of the bulb, thereby increasing the surface area of ​​the filament, allowing it to emit more light and heat, and increasing the brightness of the bulb. The filament needs to be coated with electronic powder during preparation to increase the service life of the lamp tube. After the filament is coated with electronic powder, it needs to be heated and dried.

[0003] An existing patent (publication number: CN218190795U) discloses a filament drying mechanism for use in a filament powdering device, comprising a drying base and a material receiving trough mounted on top of the drying base, with connecting seats provided on opposite sides of the material receiving trough. When the annular conveying mechanism of the filament powdering device drives the powdered filament through the drying channel, the heat emitted by the heating lamp dries the electronic powder on the filament. The structure is simple and the drying process is convenient. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved: the above-mentioned device directly dries the filament using the heat from the heating lamp, but the spiral filament has more spirals on the side, which results in different heating temperatures on the side of the spiral filament when drying, which in turn leads to poor stability in the use of the spiral filament.
