Go out all of bacterium and virus；Ultraviolet sterilization will not be produced any secondary in use without any chemical substance
Pollution.Traditional sterilization method is all to carry out sterilization using the strong oxidizing property of chlorine or ozone, and disinfectant is all in itself category
In severe toxicity, combustible material, and ultraviolet tube is not in then such potential safety hazard.So being replaced with ultraviolet sterilization traditional
Chemical sterilization has turned into present main trend.And cold cathode uv lamp pipe is more superior than hot cathode in performance, cold the moon
Have the advantage such as long-life and resistance to on-off times, excite filament to discharge electronics by high pressure, electric current is small, and caloric value is low, these
All it is the guarantee of long-life and resistance to on-off times.
At present in the packaging technology of cold cathode uv lamp, auxiliary exhaust ports are increased mostly to be vented, current technique
For, in the middle of quartz glass tube or filament sealing part with burn a duck eye, reconnect a segment process pipe, the good lamp of two ends clamp
After silk, mercury bar is put into by process duct, gaseous mixture is filled with after being vented by process duct, then sealed after Cutting process pipe again
Mouthful.Such technique presently, there are many problems：
1., matter of utmost importance is exactly that air-tightness is bad at exhaust air technique pipe, the phenomenon for easily leaking air；
2., secondly increase a segment process pipe, this segment process pipe be it is useless, auxiliary operation, complete after also need to dismantle, it is right
In uviol lamp fluorescent tube in itself for and do not exist, so indirectly wasting process duct cost.
3., it is exactly finally the problem of appearance of quartz burner, the fluorescent tube made of current technique all can in surface of the light tube
Scabbed in the presence of a sealing, influence fluorescent tube outward appearance, and after scabbing, tube outer wall out-of-flatness, the assembling in the product of influence fluorescent tube.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of cold cathode uv lamp packaging technology of exhaust-pipe-free,
In solve current cold cathode uv lamp pipe air-tightness present on encapsulation it is bad, process costs are wasted, unsightly etc. bad
Phenomenon.The cold cathode uv lamp produced by present invention process, process is simple good with air-tightness, low cost, attractive in appearance etc.

Specific embodiment
A kind of cold cathode uv lamp packaging technology of exhaust-pipe-free, comprises the following steps：
Step 1：Cut the glass tube 1 of corresponding length；
Step 2：By the clamp of the first filament 2.1 in the A sides of glass tube 1；
Step 3：From the B side pipes mouthful of glass tube 1, the second filament 2.2 is inserted；
Step 4：B sides to glass tube 1 carry out incomplete clamp；
Step 5：Mercury bar 3.1 is placed to the B sides upper end clamp opening of glass tube 1；
Step 6：After being exhausted from the B sides of glass tube 1, gaseous mixture 4 is filled with；
Step 7：Mercury bar 3.1 is gasified by pushing away mercury machine so that mercury vapour 3.2 is entered into inside glass tube 1；
Step 8：Glass tube 1 is turned upside down, the second filament 2.2 inserted in glass tube 1 falls into the glass tube 1 of incomplete clamp
B sides；
