Abstract

The utility model relates to an AC lighter of gas ranges, comprising a control box of igniting circuit and a discharging terminal. The utility model is characterized in that the igniting circuit comprises a power switch K1, a power indicator Z, a fuse R0, a capacitance C, a diode D, an igniting button switch K2 and a step-up transformer B. The ignition can be finished by pressing the igniting button switch K2 when igniting. And at the same time, the 220V alternating current power supply is cut off. The AC lighter of gas ranges is easy to operate without changing the battery. It is safe, reliable and non-pollution. It is a requisite for the gas range user.

Description

AC lighter of gas ranges

The utility model is a kind of gas cooker igniter that uses AC power, belongs to the igniter of using electric spark.

The present gas cooker igniter that uses, great majority are to utilize dc source, discharge and recharge through inverter circuit and high-frequency step-up transformer, produce high-frequency and high-voltage and light a fire, it is the cost height not only, and will regularly replace battery, makes troubles to use.

The purpose of this utility model is to design a kind of gas cooker igniter that uses AC power.

The alternating current gas cooker igniter is made up of control box that firing circuit is housed and discharge terminal.The control box body adopts withstand voltage insulating materials to make, and has the hangers that is used for fixing control box on the box body; The utility model alternating current gas cooker igniter is characterised in that described firing circuit is by power switch K ₁, power supply indicator Z, fuse R _D, capacitor C, diode D, button ignition switch K switch ₂Constitute with step-up transformer B.Power switch K ₁, the igniter button K switch ₂Normally opened contact K _2-2, step-up transformer B primary coil L ₁, diode D, button ignition switch K switch ₂Normally-closed contact K _2-1With fuse R _DBe series at 220 volts of ac power input ends successively, capacitor C and button ignition switch K switch ₂Normally opened contact K _2-2With step-up transformer B primary coil L ₁Parallel connection, power supply indicator Z and capacitor C, diode D and button ignition switch K switch ₂Normally-closed contact K _2-1Parallel connection, power switch K ₁, the button ignition switch K switch ₂Being fixed on control box with power supply indicator covers; Described discharge terminal is two stainless steel filament, by being installed in the screw of the insulation joint plate on the gas-cooker frame, respectively with the secondary coil L of step-up transformer B ₂Two ends join, and by the screw on the insulation joint plate, the discharge terminal are installed in 5 millimeters places, side top of gas burner, and two discharge terminal connections are spaced apart the 5-10 millimeter, the discharge terminal must not be directly and the gas-cooker bridge joint touch, two discharge terminals must not short circuit.The button ignition switch K switch ₂Be two groups of double-contact linked switches, in firing circuit, it is K that a winding becomes normally off _2-1, it is K that another winding becomes normally open _2-2When igniting, press the button ignition switch K switch ₂The time, K _2-1Become disconnection by normally off, meanwhile, K _2-2Become on-state by normally open.

Embodiment of the present utility model is described in conjunction with the accompanying drawings:

Fig. 1 is the firing circuit schematic diagram;

Fig. 2 is control box external form figure;

As shown in Figure 1, be connected to power switch K in the utility model firing circuit ₁, power supply indicator Z, fuse R _D, capacitor C, diode D, button ignition switch K switch ₂With step-up transformer B, step-up transformer B is by bar magnet and high strength enamelled wire, and coiling forms on bar magnet.As power switch K ₁When closed, 220 volts AC powers and firing circuit connection, power supply indicator Z is bright, at this moment the button ignition switch K switch ₂K _2-1The contact is in connection closure state, K _2-2The contact is in off-state, and 220 volts of AC powers are charged to capacitor C by diode D; When pressing the button ignition switch K switch ₂The time, K _2-1Become off-state by closure state, 220 volts of power supplys disconnect K _2-2Become on-state by off-state, make the electric charge that stores on the capacitor C by step-up transformer B primary coil L ₁Discharge is at step-up transformer secondary coil L ₂Induce high voltage, will with L ₂The two poles of the earth of the discharge terminal that joins produce electric spark, at this moment, if when the gas-cooker source of the gas opened, can light.Step-up transformer B separates 220 volts of AC powers.Pressing the button ignition switch K switch ₂The time, K _2-1Also, has only the instantaneous primary coil L that is added in step-up transformer of pulsating volage with 220 volts of Ac Dumps ₁Two ends guarantee to use to be perfectly safe.

In the present embodiment, capacitor C is selected 2.0 μ F/400V electrodeless electric capacities for use, and commutation diode is selected 2CP14 for use.

The utility model alternating current gas cooker igniter has easy to operate, need not change battery, and is safe and reliable, pollution-free, is gas-cooker user's requirement.
