Abstract

The utility model relates to a miniature jump bulb which belongs to an automatic delay switch for starting a fluorescent lamp by preheating and is used for the inner starting of a starter of the fluorescent lamp and a single-end fluorescent lamp. The utility model solves the main defects of larger volume, higher cost, poor performance, etc. of the existing similar product and has the advantages of better practicability and lower cost.

Description

Miniature jumping bubble

The utility model relates to the Auto-delay switch that a kind of fluorescent lamp pipeline start up by preheating is used, and is commonly called as to jump bubble the miniature jumping bubble that especially a kind of overall dimension is very little.

Present known jumping bubble mainly contains two kinds of contour structures (consulting " lamp and illumination " 2001/4 phase inside front cover " various electricity-saving lamps, starter are with jumping the bubble operation parameter "), and is a kind of for tack jumping bubble, is called for short flat bubble, as shown in Figure 1; The another kind of jumping for tip steeped, and is called for short the point bubble, as shown in Figure 2.Among the figure 1, glass bulb; 2, bead; 3, stem stem; 4, thermal deformation electrode; 5, indeformable electrode; 6, lead-out wire; 7, the surplus tail of blast pipe.

The design feature of flat bubble is that electrode is contained on the stem stem, and the sealing of shell is realized by the welding on glass shell and stem stem loudspeaker limit; The design feature of point bubble is that electrode is contained on the bead, and the sealing of shell is realized by the sealing by fusing of glass-tube and bead lead-out wire.For extract out in the cell-shell air with charge into working gas, the top drawing-down of point bubble glass bulb constitutes blast pipe (stem stem of flat bubble has blast pipe), after exhaust air technique is finished it is shut and forms the pinnacle shape.

Flat bubble is because of adopting stem stem, and startability is better, but volume is bigger, and price is more expensive; Without stem stem, diameter is less with bead for the point bubble, and price is lower, but startability is relatively poor, shows that stability is bad, and useful working life is shorter.Main cause is to have one section lead-in wire that is in the pipe between bead and the sealing end, and this section lead-in wire is the meeting severe oxidation when welding is sealed, and (under the atmosphere of gas discharge) can emit foreign gas and make and jump the bubble mis-behave during work.In addition, its pinnacle has also increased the length of jumping bubble.

The purpose of this utility model is exactly to solve the shortcoming that above-mentioned existing jumping bubble structure exists, and adopts new structural design, makes to jump to steep existing good startability shorter, littler overall dimension is arranged again, and cost also so lower.

The purpose of this utility model is achieved in that electrode is contained on the seal wire of bead and forms tube core, again tube core is put into the glass-tube that an end has sealed, after finishing technologies such as exhaust, glass-tube directly is connected (as welding) with bead and constitutes the sealed glass shell and complete jumping bubble, extremely shown in Figure 6 as Fig. 3.The a small amount of launching material of the interior placement of glass bulb in case of necessity is used for producing initiating electron and reduces operating voltage with coating electronic emitting material on electrode.

Owing to adopted such scheme, to jump bubble with the tack of present extensive application and compare, overall dimensions such as the length of jumping bubble, diameter are dwindled significantly, and cost reduces significantly; Jump bubble with the tip that suitable consumption is also arranged at present and compare, not only startability obviously improves, and length shortens significantly, and diameter also further dwindles, and cost also obviously reduces.The outstanding feature that size is dwindled, performance improves and cost reduces has enlarged the range of application and the ratio of performance to price that has improved product of product effectively.

Below in conjunction with accompanying drawing and embodiment the utility model is further specified:

Fig. 3 and Fig. 4 are the structure principle charts of first embodiment of the present utility model.Fig. 3 is a front view, and Fig. 4 is an end view.

Fig. 5 and Fig. 6 are the structure principle charts of second embodiment of the present utility model.Fig. 5 is a front view, and Fig. 6 is an end view.

Fig. 7 is an exhaust process key diagram of the present utility model.

Fig. 3 and embodiment illustrated in fig. 4 be a kind of polar structure that has, the area of its thermal deformation electrode (4) (U-shaped bimetal leaf) is significantly greater than the area of indeformable electrode (5).

Fig. 5 and embodiment illustrated in fig. 6 be a kind of nonpolarity structure, its two electrodes (being the thermal deformation electrode among the figure) area is equal substantially.

Fig. 3 extremely glass bulb inwall embodiment illustrated in fig. 6 all scribbles micro radioactive substances to produce initiating electron.And charge into the working gas argon gas.

From Fig. 3 to Fig. 6, all can't see blast pipe, so how, extract the air in the pipe and charge into working gas? as shown in Figure 7, the long glass-tube that tube core will be housed during exhaust inserts gas extraction system, bead is blocked in the necking section of glass-tube dexterously, because the glass-tube contact position and the blow-by of bead and necking down, gas can be finished and extract inner air tube and the essential technical process that charges into working gas out from circulation between bead and the necking down.After exhaust air technique is finished,, constitute hermetically sealed shell with the glass-tube and the bead sealing by fusing of rotation duration and degree of heating with bottleneck.Remove following unnecessary glass-tube subsequently.
