Abstract
The utility model provides an uv uv light source. The main solution does not have closely knit sealing -in between current molybdenum rod and the sealing -in portion, fluorescent tube high temperature during operation, the inside easy oxidation of molybdenum rod of sealing -in portion, problem that life hangs down. Its characterized in that: closely knit sealing -in between molybdenum rod and the sealing -in portion. Its advantage lies in forming closely knit sealing -in between molybdenum rod and sealing -in portion, and isolated oxygen gos deep into the clearance at molybdenum rod and sealing -in position, prevents that the inside molybdenum rod of sealing -in portion from continuing the oxidation at the during operation, has guaranteed the quality, has improved the life of fluorescent tube.
Description
Technical field
This utility model relates to a kind of ultraviolet source, is specifically related to a kind of uv ultraviolet source.
Background technology
Ultraviolet source is to produce the ultraviolet radiation non-illumination electric light source as main purpose, it is adaptable to the fields such as industry, agricultural, national defence and medical treatment.
The common uv ultraviolet source of one of which includes body, body two ends carry out sealing-in and form sealed portion, molybdenum rod is inserted at sealed portion center, but do not seal between molybdenum rod and sealed portion, it is impossible to the oxygen in isolation extraneous air, therefore when normally working, its high temperature produced can make the molybdenum rod within sealed portion aoxidize, thus affect the connection effect between molybdenum rod and sealed portion, and ultimately resulting in inefficacy, service life is low.
Utility model content
In order to overcome the deficiency of background technology, this utility model provides a kind of uv ultraviolet source, mainly solves not have between existing molybdenum rod and sealed portion closely knit sealing-in, and during fluorescent tube hot operation, the molybdenum rod within sealed portion easily aoxidizes, the problem that service life is low.
The technical scheme that this utility model is used: a kind of uv ultraviolet source, including body, described body two ends are provided with sealed portion, are provided with molybdenum sheet in the middle of described sealed portion, described sealed portion center is inserted with the molybdenum rod being connected with molybdenum sheet, closely knit sealing-in between described sealed portion end and described molybdenum rod.
Gap sealing glass powder between described molybdenum rod and sealed portion forms closely knit sealing-in.
In described sealed portion, the degree of depth of sealing glass powder is 1-1.5mm.
Described sealed portion outer end also sealing glass powder, its thickness is 1-1.5mm.
Described body is quartz glass tube.
The diameter of end, described body two ends radially tapers into.
The curved structure in end, described body two ends.
The beneficial effects of the utility model are: use above scheme, glass dust sealing by fusing is used to do closely knit sealing-in between molybdenum rod and sealed portion, starvation stretches into the gap of molybdenum rod and sealing-in position, prevent the molybdenum rod within sealed portion from operationally continuing oxidation, ensure that quality, improve the service life of fluorescent tube.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment uv ultraviolet source.
Fig. 2 is the enlarged diagram in Fig. 1 at A.
1-body in figure, 2-sealed portion, 3-molybdenum rod, 4-glass dust, 5-molybdenum sheet.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further:
As it can be seen, a kind of uv ultraviolet source, including body 1, described body 1 two ends are provided with sealed portion 2, being provided with molybdenum sheet 5 in the middle of described sealed portion 2, described sealed portion 2 center is inserted with the molybdenum rod 3 being connected with molybdenum sheet 5, closely knit sealing-in between described sealed portion 2 end and described molybdenum rod 3.
Doing closely knit sealing-in between molybdenum rod and sealed portion, starvation stretches into the gap of molybdenum rod and sealing-in position, prevents the molybdenum rod within sealed portion from operationally continuing oxidation, it is ensured that quality, improves the service life of fluorescent tube.
Wherein, being that the gap sealing glass powder between described molybdenum rod and sealed portion forms closely knit sealing-in, glass dust has preferably stablizes chemical property, high temperature resistant, the most more stable with glass dust sealing effectiveness.In described sealed portion 2, the degree of depth of sealing glass powder 4 is 1-1.5mm.
In order to be further ensured that sealing effectiveness, by described sealed portion 2 outer end also sealing glass powder 4, its thickness is 1-1.5mm.
Further, described body 1 uses quartz glass tube, quartz glass tube to have the advantages such as high temperature resistant, corrosion-resistant, Heat stability is good, light transmission are good, electrical insulation capability is good, is more applicable for ultraviolet light.
As it is shown in figure 1, the curved structure in end, described body 1 two ends, and its diameter radially outwards between diminish, the design of this structure can not only strengthen the intensity of of body 1 itself, and outward appearance is the most attractive in appearance, and effect is more preferable.
Embodiment is not construed as the restriction to utility model, but any based on spirit improvements introduced of the present utility model, all should be within protection domain of the present utility model.
