Problems solved by technology
[0002] In recent years, high-voltage pulsed arc ignition technology has been widely used in the field of gas stoves. The power supply is generally battery-powered. Because the battery is a consumable part, after a period of use, the battery power will decrease, resulting in unsuccessful ignition. Since most users have been accustomed to the traditional piezoelectric ceramic igniter type gas cooker, they ignore the fact that there is a battery in the gas cooker, and the battery is insufficient and needs to be replaced. Therefore, when the battery runs out and the ignition fails, most Users think that it is other faults of the gas stove, but they do not know that it can be solved by simply replacing the battery, so they will directly resort to the after-sales service of the gas stove manufacturer. This phenomenon not only brings inconvenience to the user, but also affects the manufacturer The dealer increases the unnecessary after-sales service, which brings a large amount of unnecessary after-sales service expenses

The invention relates to a circuit which can automatically prompt when the electric quantity of battery used in combustion tools is not enough, wherein the invention is characterized in that: the invention comprises a delay control circuit powered by the battery, while its input is connected to the ignite trigger output of igniter of combustion tools, to continuously output high-voltage signal in some time after igniting and closing; a voltage checking circuit whose input is connected to the output of delay circuit, while its output will output low-voltage signal when the voltage signal of input is over low; and an alarm prompt circuit whose input is connected to the output of delay control circuit and output is connected to the output of voltage checking circuit, while it can control the alarm element when the output obtains low-voltage signal. With said invention, the circuit will continuously alarm for seconds when the ignite switch is connected and the electric quantity is low.
Description
Technical field [0001] The present invention relates to a control circuit on a gas appliance, in particular to a circuit that uses a battery-powered pulse igniter to ignite a household gas-burning stove whose battery power is insufficient to automatically remind when the ignition is successful. Background technique [0002] In recent years, the high-voltage pulsed arc ignition technology has been widely used in the field of gas stoves. The power supply is generally in the form of batteries. Because the battery is a consumable part, after a period of use, the battery power will decrease, resulting in unsuccessful ignition. Since most users are accustomed to traditional piezoelectric ceramic ignitor gas stoves, they have ignored the fact that there are batteries in the gas stoves and the battery is insufficient to be replaced. Therefore, when the battery is exhausted and the ignition is unsuccessful, most The users think it is other faults of the gas stove, and they don’t know that...
