Abstract

The invention discloses a system for preventing long-time ignition failure of a gas stove on the basis of gas outlet pressure. The system comprises a pressure sensor, a controller, a thermocouple interface module and an electromagnetic valve; the pressure sensor is mounted between a gas stove assembly and a gas outlet; the controller receives signals of the pressure sensor and the thermocouple interface module; the electromagnetic valve is mounted at a gas inlet of the gas stove; the controller acquires the gas outlet flow velocity of the gas outlet through the pressure sensor, detects whetherignition is successful through the thermocouple interface module and controls opening and closing of gas inlet of the gas stove through the electromagnetic valve. The problem that the gas concentration exceeds the standard due to repeated ignition of an existing gas stove in a short time is solved.

Description

technical field [0001] The invention relates to a safety protection device for a gas cooker, in particular to a system for preventing a gas cooker from being ignited for a long time based on the gas outlet pressure. Background technique [0002] At present, the gas cooker has a protective device to prevent gas leakage during the operation of the gas cooker, but the protective measures are still insufficient, such as the lack of protective devices for misignition or long-term ignition failure. , it is likely to accidentally put a heavy object on the gas stove, or press the ignition for a long time during use. Such a situation will easily lead to excessive battery loss and gas leakage after the battery is exhausted. There have been protection devices for long-term ignition failures, but the existing protection devices cannot prevent multiple ignition failures in a short period of time. When users frequently try to ignite the gas stove because the gas stove fails to ignite norm...
