Problems solved by technology
However, if the battery power supply is not only used as ignition power supply, but also as alarm power supply, and to meet the needs of a replacement cycle of half a year, there is a great difficulty; The consequences of wasting resources and polluting the environment will also bring bad experience to users; at the same time, due to the relatively large power consumption of the gas sensor, the core component of the alarm, and other electronic components in the measurement circuit, if the The detection of ambient gas will also make the dry battery unable to meet the use conditions of the half-year service cycle, so it is difficult to use the dry battery as the power supply for the alarm

Embodiment Construction
[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0023] The method for using the double-mode stove gas alarm of the present embodiment in the dry battery power supply mode comprises the following steps:
[0024] S1. Sensor type selection: select the sensor that monitors the gas leakage concentration in the environment in the gas alarm, and use the catalytic combustible gas sensor, semiconductor heating type sensor and normal temperature semiconductor type commonly used in the civilian market. Sensor as an optional model;
[0025] S2. Power supply selection: Two No. 1 dry batteries are used as the power supply of the gas alarm. The power of the commonly used No. 1 dry batteries is mostly 2000mA·h, but the actual usable power is only 1000mA·h, and the utilization efficiency is generally in About 80...

The invention relates to the technical field of power supply control and especially relates to an application method of a dual-mode kitchen range combustion gas alarm under a dry cell power supply mode. The method comprises the following steps: S1, performing sensor type selection; S2, performing power supply source type selection; S3, taking time T1 as upper-limit time of a detection period; S4, enabling default work time T2 to be smaller than the upper limit time T1 of the detection period; S5, after each default work time T2 ends, comprehensively starting a detection circuit of the combustion gas alarm, wherein time consumed by the combustion gas alarm under a comprehensive starting state is intermittent starting time T3; and T6, if within the intermittent starting time T3, a sensor does not detects combustion gas leakage, after the intermittent starting time T3 ends, entering next default work time T2. According to the invention, power consumption of the alarm is saved and the electric quantity utilization rate utilization rate of dry cells is effectively improved by use of a mode of cooperation between intermittent detection and default work, the two D-size dry cells can be taken as an ignition power source of a combustion gas kitchen range and can also be taken as a work power source of the kitchen range alarm, and the replacement period is quite long.
Description
technical field [0001] The invention relates to the technical field of power supply control, in particular to a method for using a dual-mode stove gas alarm in a dry battery power supply mode. Background technique [0002] The dual-mode stove gas alarm is an alarm with two power supply modes, namely: one mode uses the mains as the power supply of the alarm, and the other mode uses two No. 1 dry batteries in series as the alarm The power supply, the alarm composed of these two power supplies integrated on a PCB board, the user can choose any one of them to use according to the conditions of use, thus forming a dual-mode stove gas alarm. This design consideration is mainly based on: if the user is convenient to use the mains power, the alarm can be directly powered by the mains power. For some users who are inconvenient to use the mains power, the conversion circuit of the PCB board can automatically switch to the dry battery as a power supply. The power supply mode of the po...
