Abstract
The utility model discloses a low-pressure ultraviolet germicidal lamp tube which comprises a straight tube type lamp tube and a lamp cap which is connected with the lamp tube in a sealing way; mercury and inert gas are filled in the lamp tube; two ends of lamp tube are also respectively provided with a filament; the filaments which are in series connection with metal guide wires arranged at the outer part of the lamp tube are connected with an external power supply through two metal pins arranged on one of the lamp caps; and a starter arranged in one of the lamp caps is connected with the metal guide wires in series. In the low-pressure ultraviolet germicidal lamp tube, as the filaments are in serial connection through the metal guide wires, a single-end double-pin structure is realized, and the structure of the lamp tube is simplified; moreover, the starter is arranged in the lamp cap, the matching circuit design is effectively simplified; and the lamp tube has reasonable structure and reliable connection and is convenient to popularize and use.
Description
Technical field
The utility model relates to a kind of low pressure ultra-violet lamp, especially a kind of low pressure ultraviolet sterilization fluorescent tube that has only two lamp bases in same end output.
Background technology
Ultraviolet sterilization is exactly by ultraviolet irradiation, destroys and change the DNA(DNA (deoxyribonucleic acid) of microbe) structure, make the dead at once or irreproducible offspring of bacterium, reach the purpose of sterilization.Ultraviolet sterilization belongs to pure physical disinfection method, have simple and convenient, broad-spectrum high efficacy, non-secondary pollution, be convenient to management and realize advantages such as automation, along with the release of the quartz burner of various new design, the range of application of ultraviolet sterilization is also constantly enlarging.Our ultraviolet germicidal lamp used in everyday (UV lamp) is actually and belongs to a kind of hot cathode low pressure mercury lamp, adopt tungsten filament to do cathode body, its surface applied low work function metal oxide (electronics powder), after the energising, heating work by tungsten filament, make the evaporation of mercury and other materials form low-pressure mercury-vapor (10-2Pa) in fluorescent tube, the electron stream that utilizes the low work function metal oxide to produce excites low-pressure mercury-vapor to launch ultraviolet principle and produces the ultraviolet ray that sterilizing is used.
Yet, existing quartz burner all is provided with filament at the two ends of fluorescent tube usually, and use the structure of single-ended four pins, as shown in Figure 1, promptly be that the filament of a wherein end is guided to by wire guide on the stitch of the other end and drawn together, like this this type of quartz burner therein the lamp holder of an end 4 stitch are just arranged, structure is comparatively complicated.And the startup of this type of fluorescent tube needs outer circuits to realize that the design of peripheral circuit is comparatively loaded down with trivial details.
The utility model content
In order to solve the shortcoming that overcomes prior art, the utility model provides a kind of low pressure quartz burner that uses single-ended crosspointer pin to draw, and at one end the built-in starter of lamp holder has been simplified the design of peripheral circuit.
The technical solution adopted in the utility model can be described as:
A kind of low pressure ultraviolet sterilization fluorescent tube, comprise straight pipe type fluorescent tube and the lamp holder that is tightly connected with described fluorescent tube, be filled with mercury and inert gas in the described fluorescent tube, the two ends of described fluorescent tube also are respectively equipped with filament, and described filament is connected with external power source by two metal pins that are located on one of them lamp holder after being connected in series by the two strip metal seal wires that are located at described fluorescent tube outside; Also be in series with the starter that is arranged in the lamp holder between the described filament.
As a kind of improvement of above technical scheme, described starter is for jumping bubble or electric capacity.
The beneficial effects of the utility model are:
The filament of the low pressure quartz burner that the utility model proposed is connected by wire guide, has realized the structure that single-ended crosspointer pin is drawn, and has simplified the structure of fluorescent tube; And also be provided with starter in the end lamp holder of fluorescent tube, simplified the design of support circuit effectively.This lamp tube structure is reasonable, connection is reliable, is convenient to promote the use of.
Description of drawings
Fig. 1 is the structural representation of existing single-ended four pin quartz burners;
Fig. 2 is the structural representation of the quartz burner that proposes of the present utility model.
Embodiment
As shown in Figure 2, the low pressure ultraviolet sterilization fluorescent tube that the utility model proposed comprises straight pipe type fluorescent tube 1 and lamp holder 2, and described fluorescent tube 1 is tightly connected with lamp holder 2 and forms an annular seal space.Fluorescent tube 2 is filled with a certain amount of mercury and is filled with inert gases such as argon, neon or krypton, and its two ends also respectively are fixed with a filament 3.Wherein fluorescent tube 2 adopts transparency silica glass to make, and filament 3 adopts the tungsten filament of helical structure commonly used and is coated with the electronics powder.Trace Mercury during work in the filament 3 heating evaporation fluorescent tubes 1 forms low-pressure mercury vapour, and the flow of emitted electrons of being heated of the electronics powder on the filament 3 excites mercury vapour to produce ultraviolet ray simultaneously.
The innovation part of the quartz burner that the utility model proposed is, as shown in Figure 2, described filament 3 is connected with external power source by two metal pins 5 that are located on one of them lamp holder 2 after being connected in series by the wire guide 4 that is located at described fluorescent tube 1 outside.In addition, also be in series with the starter 6 that is arranged in the lamp holder 2 between the described filament 3, this starter 6 can adopt jumps bubble or electric capacity.Like this, the existing ultra-violet lamp of single-ended four stitch in the comparison diagram 1, the filament of the low pressure quartz burner that the utility model proposed is connected by wire guide, has realized the structure that single-ended crosspointer pin is drawn, and has simplified the structure of fluorescent tube; And also be provided with starter in the end lamp holder of fluorescent tube, simplified the design of support circuit effectively.This lamp tube structure is reasonable, connection is reliable, is convenient to promote the use of.
The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection range, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection range of the present utility model.
Claims (2)
1. low pressure ultraviolet sterilization fluorescent tube, comprise straight pipe type fluorescent tube (1) and the lamp holder (2) that is tightly connected with described fluorescent tube (1), described fluorescent tube is filled with mercury and inert gas in (1), the two ends of described fluorescent tube (1) also are respectively equipped with filament (3), it is characterized in that: described filament (3) is connected with external power source by two metal pins (5) that are located on one of them lamp holder (2) after two outside strip metal seal wires (4) of described fluorescent tube (1) are connected in series by being located at; Also be in series with the starter (6) that is arranged in the lamp holder (2) between the described filament (3).
