Abstract
The utility model discloses a special heating fluorescent tube of printer, 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 through two molybdenum rod lead -out wires respectively, the other end and the connection of electric lines of every molybdenum foil, the other end of electric wire is connected with the terminal, the molybdenum foil seals in the porcelain head with the link of electric wire, 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 has warp after the tungsten filament receives the shock or has used for a long time through being provided with a plurality of heat insulating ring at quartz glass tube inner circle interval, 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 a kind of special heating fluorescent tube 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 the special heating fluorescent tube of a kind of safe and reliable printer.
This utility model solves the technical scheme that its technical problem adopts:
A kind of special heating fluorescent tube of printer, including quartz glass tube and the tungsten filament being arranged in quartz glass tube, described tungsten filament two ends connect respectively through two molybdenum rod lead-out wires and two molybdenum foils, the other end of each molybdenum foil is connected with electric wire, the other end of described electric wire is connected to terminal, the link of described molybdenum foil and electric wire is sealed in porcelain head, is filled with halogen gas in described quartz glass tube, and 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 continuous dense distribution.
As the improvement of technique scheme, the terminal of described quartz glass tube wherein one end is additionally provided with and moulds shell, described in mould shell and be arranged in printer body.
As the improvement of technique scheme, described quartz glass tube is provided with an exhaust nozzle, and the diameter of described quartz glass tube is 6mm ± 0.5mm, and described exhaust nozzle height is less than 4.5mm.
The beneficial effects of the utility model have:
This fluorescent tube, 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, and tungsten filament can ride in heat insulation loop, it is prevented that quartz glass tube is melted, and can play the effect of protection quartz glass tube, 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, a kind of special heating fluorescent tube 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 connect respectively through two molybdenum rod lead-out wires and two molybdenum foils 3, molybdenum rod lead-out wire has good electrovacuum high-temperature behavior, and the other end of each molybdenum foil 3 is connected with electric wire, and the other end of electric wire is connected to terminal 4, the link of molybdenum foil 3 and electric wire is sealed in porcelain head 5, is filled with halogen gas in quartz glass tube 1.
Wherein, the tungsten filament 2 helical form in continuous dense distribution, tungsten filament 2 is made to keep good elastic helix shape and keep extended state, reduce sag height, quartz glass tube 1 inner ring is arranged at intervals with some heat insulation loop 6, it is prevented that tungsten filament 2 directly rides on quartz glass tube 1, and wherein heat insulation loop 6 is also adopted by tungsten filament and makes, its fusing point is far above the fusing point of quartz glass tube 1, safe and reliable.
Moulding shell 7 additionally, be additionally provided with on the terminal 4 of quartz glass tube 1 wherein one end, mould shell 7 and be arranged in printer body, quartz glass tube 1 is provided with an exhaust nozzle 8, and exhaust nozzle 8 height is less than 4.5mm, and the diameter of quartz glass tube 1 is 6mm ± 0.5mm.
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.
