Description

Technical Field

[0001] This utility model belongs to the field of halogen lamp technology, specifically relating to a stable oven lamp. Background Technology

[0002] Currently, oven lights on the market rely on a single or double-point horizontal support mechanism on the bulb to prevent the filaments from touching each other. An oven is a specific environment, and a proper oven light needs to be small in size, heat-resistant, shockproof, short-circuit resistant, and explosion-proof. Heat resistance and small size are unique advantages of halogen lamps. Shockproof, short-circuit resistant, and explosion-proof require analysis of the halogen lamp's operating principle. Halogen lamps maintain their lifespan through the circulation of halogen gas and the tungsten filament inside the lamp. From the moment it is lit, the tungsten filament begins to consume and evaporate, becoming thinner, softer, and longer. This becomes more pronounced under vibration and high temperatures. A single horizontal support point is insufficient to prevent short circuits and explosions. While a double-point support can prevent this, the double compression within the lamp's small internal space results in very little gas available for sustaining the filament, naturally leading to a short lifespan. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies in meeting the needs of practical applications, and to provide a halogen lamp that does not short-circuit or explode, and has a longer service life and higher safety performance in high-temperature and vibration environments.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stable oven lamp, comprising a bulb shell, an exhaust tip at the top of the bulb shell, a clamping part at the bottom of the bulb shell, molybdenum sheets symmetrically arranged inside the clamping part, a lamp base at the bottom of the molybdenum sheets, a tungsten filament at the top of the molybdenum sheets, a supporting glass block corresponding to the tungsten filament inside the bulb shell, and positioning grooves symmetrically opened at the top of the supporting glass block.

[0005] Preferably, the edges of the positioning groove are smoothed by a passivation process.

[0006] Preferably, the tungsten wire is placed in the middle of the positioning groove.

[0007] Preferably, the supporting glass block and the bubble shell are made of the same quartz glass material, and the upper end of the supporting glass block is set as a hollow column.

[0008] Preferably, the lower ends of the bubble shell and the supporting glass block are formed into a fused glass wall by heating and extrusion, and filament positioning posts are symmetrically arranged inside the supporting glass block, with the filament positioning posts distributed on both sides of the tungsten filament.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention inserts a supporting glass block inside the bubble shell and supports the tungsten wire through a positioning groove. The width of the supporting block is similar to the inner diameter of the bubble shell. The bubble shell is then heated and clamped to fix it, so that the supporting glass block is fixed to the inner wall surface of the bubble shell to form a fused glass wall. This improves the processing efficiency of the product, reduces the processing difficulty, ensures the support effect on the tungsten wire, and extends the service life of the equipment.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 The present invention provides the following technical solution: a stable oven lamp, including a bulb shell 2, an exhaust tip 1 at the top of the bulb shell 2, a clamping part 7 at the bottom of the bulb shell 2, molybdenum sheets 5 symmetrically arranged inside the clamping part 7, a lamp foot 6 at the bottom of the molybdenum sheets 5, a tungsten wire 4 at the top of the molybdenum sheets 5, a supporting glass block 3 corresponding to the tungsten wire 4 inside the bulb shell 2, and positioning grooves 8 symmetrically opened at the top of the supporting glass block 3.

[0018] Specifically, the edges of the positioning groove 8 are smoothed by a passivation process.

[0019] By adopting the above technical solution, the damage of the positioning groove 8 to the tungsten wire 4 is reduced, and the service life of the equipment is improved.

[0020] Specifically, the tungsten wire 4 is placed in the middle of the positioning groove 8.

[0021] By adopting the above technical solutions, the stability of tungsten wire 4 in use is ensured, and the quality of use is further improved.

[0022] Specifically, the supporting glass block 3 and the bubble shell 2 are made of the same quartz glass material, and the upper end of the supporting glass block 3 is set as a hollow column.

[0023] By adopting the above technical solution, it is easier to flatten and clamp the glass block 3, thus improving the convenience of equipment processing.

[0024] Specifically, the lower ends of the bubble shell 2 and the supporting glass block 3 are heated and extruded to form a fused glass wall 9. The supporting glass block 3 is symmetrically provided with filament positioning posts 10, and the filament positioning posts 10 are distributed on both sides of the tungsten filament 4.

[0025] By adopting the above technical solution, the support strength is improved, ensuring the positioning quality of tungsten wire 4.

[0026] The working principle and usage process of this utility model are as follows: When using this utility model, when installing the tungsten wire 4 inside the bubble shell 2, first insert the supporting glass block 3 into the inside of the bubble shell 2 and support the tungsten wire 4 through the positioning groove 8. First heat the surface of the bubble shell 2, and then clamp and flatten the entire front of the bubble shell 2 so that the supporting glass block 3 is fixed to the inner wall surface of the bubble shell 2 and forms a fused glass wall 9, preventing the supporting glass block 3 from shaking and ensuring its support effect on the tungsten wire 4. Then, heat the lower half of the bubble shell 2 to form the clamping and sealing part 7.
