Several sensor circuits, each sensor circuit when this secondary side high-pressure side detects flame, makes this firing circuit stop to produce high-tension electricity to a secondary side that should at least one ignition coil.
The secondary side earth terminal of described each ignition coil is via neon lamp ground connection.
The beneficial effects of the utility model are:
1, this ignitor induction type automatic ignitor because ignitor has the function of induction flame concurrently, therefore can omit induction coil, thereby significantly reduce manufacturing cost.
2, this ignitor induction type automatic ignitor can use the alternating current operation.
Description of drawings
Fig. 1 is the circuit diagram of ignitor induction type automatic ignitor first embodiment;
Fig. 2 is the circuit diagram of ignitor induction type automatic ignitor second embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the circuit diagram of ignitor induction type automatic ignitor first embodiment.This igniter 10 is formed by connecting according to the circuit of accompanying drawing or certain logic by operating portion 12, AC-DC change-over circuit 14, firing circuit 16 and sensor circuit 18.Wherein:
AC-DC change-over circuit 14 is made up of transformer T1, resistance R 1 and diode D1, with after alternating current transformation, current limliting and the rectification, and the required direct current of supply centre firearm 10 work.Above-mentioned transformer T1 is an isolating transformer, disturbs with the electric field that intercepts between its primary side and the secondary side, reaches the purpose of insulation, leakproof.
According to above-mentioned ignitor induction type automatic ignitor 10, when ignition switch SW1 was the OFF state, AC-DC change-over circuit 14, firing circuit 16 and sensor circuit 18 were to be in static state.
When ignition switch SW1 was the ON operation, alternating voltage was transformed into desired voltage through isolating transformer T1, and via charging to capacitor C 1 after resistance R 1 current limliting and the diode D1 rectification, charged to capacitor C 3 through resistance R 2 simultaneously; When capacitor C 3 voltages are charged to two-way dipole lock stream device D4 conducting, therefore thyristor D3 is triggered and conducting, so capacitor C 1 discharge makes the ignition coil K1 generation high-tension electricity that boosts, this high-tension electricity is sent to ignitor via high-voltage conducting wires, make its generation spark (electric arc) and light gas-air mixture, form flame.On the other hand, above-mentioned voltage makes electric crystal Q3 action via capacitor C 6, resistance R 19 and R25, and after electric crystal Q3 action, electric crystal Q1 is cut off and stop conducting.
In case after ignitor detects flame, utilize the rectification of flame that voltage is eliminated the positive voltage of capacitor C 6 via resistance R 7, send a telegraph crystal Q3 and can't move; When electric crystal Q3 stop conducting, then electric crystal Q1 action and the positive voltage of capacitor C 3 eliminated can't trigger thyristor D3, so capacitor C 1 stops discharge, and ignition coil K1 thereby stop to produce high-tension electricity.
In addition, second embodiment that the utility model also can be is as shown in Figure 2 duplicated combinations such as the ignition switch SW1 among Fig. 1, ignition coil K1 and sensor circuit 18, and is increased capacity accordingly, uses to be fit to many mouthfuls of stoves.Need know that in order to simplify the number of ignition coil K1, only use three ignition coil K1, K2 and K3 in the present embodiment, the every bit fire coil has a primary side and two secondary sides; In other words, two shared primary sides of secondary side.So have six secondary sides, can supply six mouthfuls of stoves and use.The operation principle of present embodiment is identical with the embodiment shown in first figure, and therefore no longer explanation is only labeled a in the component symbol back of Fig. 2 and first embodiment does difference at this.
As mentioned above,,, therefore can omit induction coil, significantly reduce manufacturing cost because ignitor has the function of induction flame concurrently according to ignitor induction type automatic ignitor of the present utility model.
Again, this ignitor induction type automatic ignitor can use the alternating current operation.
Certainly, the foregoing description can not break away under the scope of the present utility model in addition some variations, thus above explanation comprises and accompanying drawing shown in whole items should be considered as exemplary, but not in order to limit protection domain of the present utility model.
