Abstract
The utility model discloses a special halogen heating fluorescent tube of printer, its characterized in that: including quartz glass tube and the tungsten filament of setting in quartz glass tube, the tungsten filament both ends are connected with two molybdenum foils respectively, and every molybdenum foil is connected with the molybdenum guide arm, the stainless steel terminal is connected to the outer end of molybdenum guide arm, the stainless steel terminal is the key form, the molybdenum foil is encapsulated the both ends at quartz glass tube, the quartz glass tube intussuseption is filled with halogen gas, quartz glass tube inner circle interval is provided with a plurality of heat insulating ring. This fluorescent tube structure is very simple, through being provided with a plurality of heat insulating ring at quartz glass tube inner circle interval, has warp after the tungsten filament receives the shock or has used for a long time, and the tungsten filament can be taken on heat insulating ring, prevents that quartz glass tube from being melted, can play protection quartz glass tube's effect, safe and reliable.
Description
Technical field
This utility model relates to printer part field, particularly relates to the special halogen heating fluorescent tube of a kind of printer.
Background technology
In the heating fusing system of printer, heating lamp is arranged in fixing heating roller as thermal source. Fixing heating roller seamless Al-alloy pipe is made, and pipe thickness is between 1��3mm, and surface scribbles politef, in case the powdered ink of fusing adheres on roller during fastening shadow. During heating lamp work, by about fixing roller heating temperatures to 185 DEG C, now heating lamp is disconnected by critesistor, fixing roller is started working, the method utilizing pressurization hot melt makes the powdered ink that printing is adsorbed on paper dissolve, and the powdered ink dissolved immerses in printing paper, forms still image. Owing to tengsten lamp emits light and heat in use, although temperature does not reach the fusing point of tungsten filament, but tungsten filament is constantly vaporized once use of a specified duration, increasingly thinner, it is uneven that the nuance of material etc. may result in heating, causes tungsten filament can constantly change curved shape in this process, tungsten filament is easy to take on glass tubing, owing to the fusing point of glass tubing is relatively low, thus glass tubing is likely to be melted, and easily causes accident.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, this utility model provides a kind of simple in construction, the special halogen heating fluorescent tube of safe and reliable printer.
This utility model solves the technical scheme that its technical problem adopts:
The special halogen heating fluorescent tube of a kind of printer, including quartz glass tube and the tungsten filament being arranged in quartz glass tube, described tungsten filament two ends are connected with two molybdenum foils respectively, each molybdenum foil is connected with molybdenum guide rod, the outer end of described molybdenum guide rod connects tainless terminal, and described tainless terminal is key shape, and described molybdenum foil is encapsulated in the two ends of quartz glass tube, being filled with halogen gas in described quartz glass tube, described quartz glass tube inner ring is arranged at intervals with some heat insulation loop.
As the improvement of technique scheme, described tungsten filament is the helical form of discontinuous dense distribution, and described tainless terminal is key shape.
Improvement as technique scheme, described quartz glass tube is provided with an exhaust nozzle, the diameter of described quartz glass tube is 6mm �� 0.5mm, and described exhaust nozzle height is 110mm �� 5mm less than the distance of 4.5mm, described exhaust nozzle and the nearest one end of quartz glass tube.
The beneficial effects of the utility model have:
This lamp tube structure is very simple, by being arranged at intervals with some heat insulation loop at quartz glass tube inner ring, deforms after tungsten filament is shaken or used of a specified duration; tungsten filament can ride in heat insulation loop; prevent quartz glass tube to be melted, the effect of protection quartz glass tube can be played, safe and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail, wherein:
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Detailed description of the invention
Referring to Fig. 1 and Fig. 2, the special halogen heating fluorescent tube of a kind of printer of the present utility model, including quartz glass tube 1 and the tungsten filament 2 being arranged in quartz glass tube 1, tungsten filament 2 two ends are connected with two molybdenum foils 3 respectively, molybdenum foil 3 is connected with tungsten filament 2 by molybdenum adapter, molybdenum adapter has good electrovacuum high-temperature behavior, each molybdenum foil 3 is connected with molybdenum guide rod 4, the outer end of molybdenum guide rod 4 connects tainless terminal 5, tainless terminal 5 is in key shape, can be connected with extraneous wire easily, it is filled with halogen gas in quartz glass tube 1, molybdenum foil 3 is encapsulated in the two ends of quartz glass tube 1.
Wherein, the tungsten filament 2 helical form in discontinuous dense distribution, tungsten filament 2 is made to keep good elastic helix shape, reducing sag height, quartz glass tube 1 inner ring is also arranged at intervals with some heat insulation loop 6, and every section of helical tungsten filamen 2 outer shroud is equipped with heat insulation loop 6, prevent tungsten filament 2 from directly riding on quartz glass tube 1, wherein heat insulation loop 6 is also adopted by tungsten filament and makes, and its fusing point is far above the fusing point of quartz glass tube 1, safe and reliable.
Additionally, be additionally provided with an exhaust nozzle 7 on quartz glass tube 1, exhaust nozzle 7 height is less than 4.5mm, and the diameter of quartz glass tube 1 is 6mm �� 0.5mm, and the distance of exhaust nozzle 7 and the nearest one end of quartz glass tube 1 is 110mm �� 5mm.
The above, simply better embodiment of the present utility model, but this utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, all should belong to protection domain of the present utility model.
