Examples

Referring to fig. 1, the utility model provides a burner igniter with safety prompt, comprising: an igniter assembly 10, a control center 20 and an ion probe 30;

the igniter assembly 10 includes a burner 11 and a gas channel 12 communicating with the burner 11; the gas channel 12 is provided with a first electromagnetic valve 31, and the first electromagnetic valve 31 is electrically connected with the control center 20 and used for conducting or closing the gas channel 12;

the ion probe 30 is arranged close to a fuel gas outlet of the burner 11, the control center 20 comprises a capacitor 21, and the capacitor 21 is electrically connected with the ion probe 30; when the gas of the burner 11 is burnt, the ion probe 30, the flame and the bottom shell of the burner 11 form a conductive loop and charge the capacitor 21; the control center 20 can detect the charging state of the capacitor 21.

In the igniter of the gas appliance, when gas is combusted, the control center 20 controls the first electromagnetic valve 31 to be opened, so that the gas channel 12 is communicated, and the gas is ignited at the gas outlet position of the burner 11. When the flame burns, ions which conduct in one direction are generated, so that the ion probe 30, the flame and the grounding elements such as the bottom shell of the burner 11 form a stable conductive loop, and the ion current rectified by the conductive loop charges the capacitor 21 in the circuit. The control center 20 can detect the state of charge of the capacitor 21, and when the flame maintains combustion, the capacitor 21 is in a positive charge state; when the flame is extinguished, the capacitor 21 is in a discharge or non-charge state, and after the control center 20 detects the working state of the capacitor 21, the control center can quickly respond to the working state, control the first electromagnetic valve 31 to close the gas channel 12, and synchronously generate alarm safety prompts such as sound and light.

Specifically, the igniter assembly 10 further includes a thermocouple 40, and the gas channel 12 is further provided with a second solenoid valve 41, wherein the second solenoid valve 41 is electrically connected to the thermocouple 40. Through the second electromagnetic valve 41 and the thermocouple 40, the second electromagnetic valve 41 is maintained in an open state by utilizing thermoelectric force generated by heating of the thermocouple 40, and double protection of flameout protection is realized.

Further, the igniter assembly 10 further includes a micro switch 13, and the micro switch 13 is disposed near the second solenoid valve 41 and is used for detecting the operating state of the second solenoid valve 41. Specifically, when the igniter of the gas appliance performs combustion, the knob of the gas stove is pressed and rotated to push the second electromagnetic valve 41 to be opened, the microswitch 13 is synchronously triggered to feed back a signal to the control center 20, and the control center 20 opens the first electromagnetic valve 31, so that the gas channel 12 is conducted and flame is combusted. On one hand, the combustion of the flame provides thermal electromotive force for the thermocouple 40, and the second electromagnetic valve 41 is maintained in an open state; on the other hand, the ion probe 30, the flame, and the grounding element such as the bottom case of the burner 11 form a stable conductive circuit, the capacitor 21 in the circuit is charged by the ion current rectified by the conductive circuit, and the control center 20 maintains the first electromagnetic valve 31 in the open state according to the charged state of the capacitor 21.

In this embodiment, the igniter assembly 10 further includes an ignition needle 14, the ignition needle 14 is disposed near the gas outlet of the burner 11, and the ion probe 30 is disposed on the ignition needle 14.

The buzzer 15 can sound an alarm, and the light alarm 16 can emit alarm light to remind the user that the burner 11 is in a flameout state.

In some embodiments, the lighter of the gas appliance further comprises a control panel 50, the control panel 50 is electrically connected to the control center 20, and the buzzer 15 and the light alarm 16 are mounted on the control panel 50. The user can quickly perform ignition or flame size control by manipulating the panel 50.

In some embodiments, the control center 20 further includes a timing module 22, and the timing module 22 is used for detecting the power-off time of the capacitor 21. When the power-off time of the capacitor 21 is judged to exceed the preset time, the furnace end 11 is judged to be flameout accidentally, the control center 20 controls the first electromagnetic valve 31 to close the valve, and a safety prompt of sound and light alarm is sent out. Therefore, the ion probe 30 is prevented from being disconnected from the flame due to the partial flame caused by large wind or water liquid sputtering and dropping, a false flameout state is generated, and the safety prompt of acousto-optic alarm is triggered.

Further, the preset time may be set to a range of 5s to 7 s. For example, when the timing module 22 calculates that the power-off time of the capacitor 21 reaches 5s, the control center 20 controls the first electromagnetic valve 31 to close, and simultaneously gives a sound-light alarm to give a safety prompt.

In some embodiments, the first solenoid valve 31 and the second solenoid valve 41 are one solenoid valve, and the solenoid valve is connected to the two control circuits, and the control center 20 can close the solenoid valve by determining that the burner 11 is turned off; the thermoelectric force of the thermocouple 40 disappears and the solenoid valve can be closed.
