The invention discloses an electric quantity detection circuit. The electric quantity detection circuit comprises a voltage sampling circuit, a comparator, a current-limiting resistor, a boost circuit and a time-delay circuit, wherein the voltage sampling circuit is used for sampling the voltage of an output end of the boost circuit; one of an inverted input end and a non inverting input end of the comparator can be connected with an output end of the voltage sampling circuit, and the other one of the inverted input end and the non inverting input end of the comparator can be connected with the positive pole of a cell to be detected to detect whether the voltage of the cell to be detected is lower than the preset value; a power source end of the comparator is connected with the output end of the boost circuit; an input end of the boost circuit is connected with the positive pole of the cell to be detected; and the time-delay circuit is connected with a preset key switch so as to control the boost circuit to output voltage within the preset time quantum when the key is pressed. The invention also discloses a gas-cooker. The electric quantity detection circuit reduces power consumption for electric quantity detection and prolongs the service life of the cell.
Description
technical field [0001] The invention relates to the technical field of gas cookers, in particular to a power detection circuit and a gas cooker. Background technique [0002] As we all know, the existing gas cooker is usually equipped with a power detection circuit to detect the power of the battery, and when the power is low, a corresponding prompt message is output to remind the user to replace the battery, so as to ensure the normal operation of the gas cooker. However, in the traditional power detection circuit, the power detection circuit is in the detection state in real time, so the power consumption is relatively large, and the service life of the battery is affected. Contents of the invention [0003] The main purpose of the present invention is to provide a power detection circuit and a gas stove, aiming at reducing the power consumption of power detection and prolonging the service life of the battery. [0004] In order to achieve the above object, the present ...
