Abstract
The utility relates to a new fluorescent core column, which includes a vent-pipe, a horn, an electrode conducting wire, an electrode. Wherein, the internal core column is provided with a nip-gib-head and a vent-hole communicated with the vent-pipe, in particular that two sides or one side of the section of vent-pipe stretched within the horn-pipe contracts towards the pipe inside. The pipe-hole at the contracting part is smaller than the vent-hole. The contracting part within the vent-pipe can effectively block solid amalgam from moving out of the vent-hole, while the mercury vapor can still be discharged from the vent-hole located at the contracting part within the vent. The utility model has the advantage of simple structure and favorable reliability.
Description
Technical field
The utility model relates to a kind of fluorescent lamp wick column, but particularly a kind of novel fluorescence wick column of store solids amalgam.
Background technology
As everyone knows, fluorescent lamp is to utilize ultraviolet ray excited fluorescent material that mercury gas discharge produces and luminous electric light source, and wherein stem stem is one of critical piece of fluorescent tube.In the prior art, in order to make liquid amalgam can be stored in the blast pipe of stem stem and mercuryvapour can enter in the fluorescent tube again, normally glass stub and liquid amalgam are put into blast pipe inside and outside respectively, stop by the glass stub, liquid amalgam can not be moved away from steam vent and enter fluorescent tube.But, the exhaust aperture of some stem stem is bigger, when greater than glass stub external diameter, glass stub and liquid amalgam just all can be in steam vent enter fluorescent tube, the glass stub does not just work to stop liquid amalgam, and the glass stub enters the phosphor powder layer that will destroy in the fluorescent tube in the pipe, has a strong impact on the quality of fluorescent lamp.Therefore, adopt the glass stub to stop that liquid amalgam enters in the fluorescent tube, its reliability is relatively poor.
Summary of the invention
The utility model provides a kind of novel fluorescence wick column, to solve the problem that adopts the glass stub to stop the liquid amalgam poor reliability.
Described novel fluorescence wick column, comprise blast pipe, loudspeaker, electrode seal wire, electrode, stem stem the inner is provided with flat champ head and the steam vent that communicates with blast pipe, particularly stretches contraction in pipe in this section blast pipe both sides in oviduct or the side, and the pore of this contraction place is less than steam vent.
The utility model since stretch this section blast pipe both sides in oviduct or a side in pipe, shrink, and the pore of this contraction place make to place the interior liquid amalgam of blast pipe to be blocked in the contraction place, and mercuryvapour still can enter in the fluorescent tube less than steam vent.Its simple in structure, good reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 analyses and observe left TV structure schematic diagram for A-A among Fig. 1.
Fig. 3 is the structural representation of another embodiment of the utility model.
Fig. 2 analyses and observe left TV structure schematic diagram for B-B among Fig. 3.
Embodiment
Fig. 1, Fig. 2 among Fig. 3, Fig. 4, comprise blast pipe 1, electrode seal wire 2, oviduct 3, steam vent 4, flat champ head 5, electrode 6.
In Fig. 1, Fig. 2, blast pipe 1, electrode seal wire 2, oviduct 3, electrode 6 are connected as a single entity, the steam vent 4 that stem stem the inner is provided with flat champ head 5 and communicates with blast pipe is stretched in this section blast pipe two side direction pipes in oviduct 3 and is shunk, and the pore of this contraction place is less than steam vent 4.
In addition, as shown in Figure 3, Figure 4, stretching in this section blast pipe in oviduct 3 also can be to shrink in the side direction pipe, and the pore of this contraction place is less than steam vent 4.
During application, liquid amalgam is put into pore from the blast pipe external port, the contraction place of stretching this section blast pipe in oviduct just can stop liquid amalgam reliably, after blast pipe outer end envelope is cut, this liquid amalgam just is stored in this blast pipe reliably, and mercuryvapour still can enter in the fluorescent tube by exhaust apertures.Therefore, the contraction place in the blast pipe can stop effectively that liquid amalgam moves away from steam vent, and mercuryvapour still can be discharged from steam vent and enter in the fluorescent tube.It is simple in structure, good reliability.
Claims (1)
1. novel fluorescence wick column, comprise blast pipe, loudspeaker, electrode seal wire, electrode, stem stem the inner is provided with flat champ head and the steam vent that communicates with blast pipe, it is characterized in that: stretch contraction in pipe in this section blast pipe both sides in oviduct or the side, the pore of this contraction place is less than steam vent.
