Abstract
The utility model discloses a silicon nitride ceramic ignition device, which comprises a heating element, a ceramic fixed base and high temperature resistance power supply line. The heating element is composed of a silicon nitride ceramic bar and resistance wire which is cured in the inner chamber of the silicon nitride ceramic bar passing through and extending out of the ceramic fixed base; ceramic filler is arranged between the end of the silicon nitride ceramic bar and the ceramic fixed base; the high temperature resistance power supply line is connected with the resistance wire at the end of the silicon nitride ceramic bar and extends out from the back end of the silicon nitride ceramic base. The utility model has the advantages of safe and reliable, stable performance and long service life.
Description
Technical field
The utility model relates to the ignition mechanism in the middle of the automobile oil heater, more precisely the silicon nitride ceramics ignition mechanism in the middle of the automobile oil heater.
Background technique
At present, traditional automobile oil heater all adopts resistance wire formula ignition mechanism, when power on/off, because of the very fast technology form that changed of resistance wire that colds and heat succeed each other, resistance wire is exposed in the air, in cold and hot changes with air in oxygen affine, form patina, when the patina accumulation arrived certain thickness, heat dissipation potential descended, and is difficult to light fuel oil, heat dissipation potential reduces, very fast scaling loss, when resistance wire contains impurity, on the impurity node because of temperature variation, cause coefficient of thermal expansion and contraction difference, the very fast fracture of resistance wire, in addition, resistance wire formula ignition mechanism also exists thermal efficiency decay fast, poor reliability, there are not defectives such as flame monitoring function.
The model utility content
At the deficiency that above-mentioned prior art exists, the silicon nitride ceramics ignition mechanism that the purpose of this utility model is to provide a kind of safe and reliable, stable performance and greatly prolongs working life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of silicon nitride ceramics ignition mechanism, comprise heater, ceramic fixed pedestal and high temperature resistant power line, described heater is made up of silicon nitride ceramics rod and resistance wire, resistance wire is solidificated in the inner chamber of silicon nitride ceramics rod, it is protruding that the silicon nitride ceramics rod passes ceramic fixed pedestal, be provided with ceramic packing between its afterbody and the ceramic fixed pedestal, high temperature resistant power line links at the afterbody and the resistance wire of silicon nitride ceramics rod, and outwards draws from the rear end of ceramic fixed pedestal.
Described ceramic fixed pedestal offers circular groove on the outer peripheral surface of its front end.
The resistance wire of the utility model heater is solidificated in the inner chamber of silicon nitride ceramics rod, its high-strength hot laminated structure has limited the variation of electric cocainine because of colding and heat succeed each other and producing securely, make the variation coefficient of different material drop to minimum, thereby can not be out of shape, because resistance wire does not contact with air, add the silicon nitride ceramics surface and have decontamination function, so the thermal efficiency significantly improves, can reach more than 5000 hours working life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of reference numerals is as follows:
1---heater
2---ceramic fixed pedestal
3---high temperature resistant power line
4---ceramic packing
5---circular groove
As shown in Figure 1, this silicon nitride ceramics ignition mechanism is mainly by heater 1, pottery fixed pedestal 2 and high temperature resistant power line 3 are formed, heater 1 is made up of silicon nitride ceramics rod and resistance wire, resistance wire is solidificated in the inner chamber of silicon nitride ceramics rod, silicon nitride (Si3N4) is the high-strength covalent compound of building, high tenacity, corrosion-resistant, nonmagnetic, selflubricating, excellent insulation, good heat conduction, place silicon nitride powder through moulding resistance wire, after hot pressed sintering and the machining moulding, just made novel heater 1, it is protruding that the silicon nitride ceramics rod passes ceramic fixed pedestal 2, be provided with ceramic packing 4 between its afterbody and the ceramic fixed pedestal 2, high temperature resistant power line 4 links at the afterbody and the resistance wire of silicon nitride ceramics rod, and outwards draw from the rear end of ceramic fixed pedestal 2, ceramic fixed pedestal 2 offers circular groove 5 on the outer peripheral surface of its front end.
The utility model proves through a large amount of scientific experimentations; its performance is far superior to the employed resistance wire formula of traditional automobile oil heater igniter plug safety; reliably; its life-span reached more than 5000 hours; especially stable hot resistance change curve; for the automatic control of automobile oil heater provides reliable parameter; has igniting; the flame monitoring dual functions; be the igniting original paper during startup; be the monitoring original paper during work; its working procedure is: heater is received the enabled instruction igniter plug and is promptly begun to carry out preheating; the oxygen supply blower fan starts synchronously; operating voltage is 10V, and operating voltage is reduced to 9V after the fuel delivery, enters the flame inquiry phase; control system is cut off the igniter plug working power automatically and is determined whether to have produced flame (cautious is 0.6 Ω) with the igniter plug change in resistance; in normal temperature-rise period, combustion regime is being monitored at any time, as flame-out its resistance value that meets accident can descend rapidly, when resistance value drop to cautious below; the heater autostop restarts once by setting.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; though but on its shape or structure, do any variation, every identical with the utility model or akin technological scheme is all within its protection domain.
