Abstract
A kind of electric supply installation of fuel heater glow plug, comprise switch element and connected power supply sampling unit, modulating unit and output unit, the output of sampling unit is connected with the input of output unit through behind the modulating unit, and the latter's output is connected with glow plug.The utility model is by the full-automatic program control of heater controller, to glow plug pulsation power supply.The reliability of heater igniting and the life-span of glow plug have been improved greatly, removed former dropping resistor, greatly reduced power supply power consumption, got rid of the unsafe factor that dropping resistor brings in ignition process, make the heater outward appearance succinct more smooth, easy for installation simultaneously.
Description
Technical field
The utility model relates to another electric supply installation of fuel heater glow plug, is used for powering to glow plug when fuel heater is lighted a fire.
Background technology
Before the utility model was made, in prior art, the glow plug electric supply installation of fuel heater was that control element is directly powered to glow plug by power supply by dropping resistor.Its defective is: the power that the power ratio glow plug that 1. consumes on the dropping resistor consumes is big 3 times, and produces a large amount of heats, has consumed the energy in vain.2. dropping resistor places the heater outside, neither attractive in appearancely can bring unsafe factor again in ignition process.3. glow plug voltage changes with supply voltage, and easily overvoltage damages glow plug.
Summary of the invention
The purpose of this utility model just provides a kind of electric supply installation of fuel heater glow plug, to solve a large amount of energy of dropping resistor consumption that prior art exists; Dropping resistor places the heater outside, neither attractive in appearancely can bring unsafe factor again in ignition process; Glow plug voltage changes with supply voltage, and easily overvoltage damages the problem of glow plug.
In order to achieve the above object, the utility model is taked following technical measures: comprise switch element and connected power supply sampling unit, modulating unit and output unit, the output of sampling unit is connected with the input of output unit through behind the modulating unit, and the latter's output is connected with glow plug.
Described power supply sampling unit is made up of dividing potential drop, voltage stabilizing and filter circuit, is used for obtaining a magnitude of voltage from the supply voltage dividing potential drop, and the latter is connected to the input of described modulating unit.
The magnitude of voltage that provides according to the power supply sampling unit is provided described modulating unit, by the pulse signal of a glow plug required pulse width of calculation process output.
Described output unit is made up of a boostrap circuit, and the pulse duration that provides according to modulating unit is for glow plug provides required magnitude of voltage.
The utility model has the advantages that: 1. saved the energy, the power that power supply provides to glow plug has only original 1/4th.2. glow plug adopts pulse (PWM modulation) step-down and according to the variation adjustment pulse duration of supply voltage, thereby has avoided the power of glow plug to be subjected to the influence of supply voltage, the useful life of having improved the ignition performance and the glow plug of fuel heater.3. because the voltage on the glow plug is pulsating dc voltage, be difficult for producing carbon distribution.4. make the more succinct smoothness of heater outward appearance.5. compare with the same model heater product, it is convenient more to install.
