Embodiment Construction
[0024] like Figure 1-6 As shown, a CO alarm for battery-type generators includes: MCU control unit U2, CO sensor detection unit U3, alarm prompt unit U4, speed detection unit U5, flameout control unit U6 and battery power supply unit U1, specifically, The MCU control unit U2 includes a single-chip microcomputer IC1, a capacitor C3, a resistor R6, and a capacitor C4. The single-chip microcomputer IC1 is a single-chip microcomputer with temperature detection, which can collect the ambient temperature of the MCU control unit U2, and is used to compensate the gas sensor caused by temperature changes. change; the capacitor C4 is a filter capacitor, and the reset pin of the single-chip microcomputer IC1 is filtered through the resistor R4 and capacitor C4; the capacitor C3 is a filter capacitor.
[0025] Specifically, the CO sensor detection unit U3 detects the CO gas concentration and outputs a weak electrical signal, amplifies the weak electrical signal and outputs it to the MCU ...

The invention discloses a CO alarm for a battery type electric generator, wherein the CO alarm comprises an MCU control unit U2, a CO sensor detection unit U3, an alarm prompt unit U4, a rotating speed detection unit U5, a flameout control unit U6 and a battery power supply unit U1; the MCU control unit U2 is used for signal analysis and processing, is in a deep dormancy state when the electric generator does not operate, and enters a dormancy and timing wake-up working state after an engine operates; the CO sensor detection unit U3 is connected with the MCU control unit and is used for converting the CO concentration in the environment into a corresponding electric signal and outputting the electric signal to the MCU control unit U2 for processing; the alarm prompt unit U4 is connected with the MCU control unit and is used for carrying out alarm prompt and alarm fault prompt on the CO concentration; the rotating speed detection unit U5 is connected with the MCU control unit and is used for collecting the running state of the electric generator and waking up the MCU control unit U2 to enter a normal working state from the deep dormancy state at the same time; and the flameout control unit U6 is connected with the MCU control unit.
Description
technical field [0001] The invention belongs to the technical field of CO alarms, in particular to a CO alarm for battery-type generators. Background technique [0002] Portable generators are widely used because of their small size, mobility, and strong adaptability to the working environment. However, since this type of generator uses a gasoline engine to drive the magneto to output electricity, a large amount of CO harmful gas will be generated during use. In many household applications, many casualties have been caused due to ignoring the CO emission problem. Many countries have begun to impose safety requirements for the mandatory installation of CO alarms for such products. In order to meet market demand, the invention provides a CO alarm for a battery-type generator. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a CO alarm for a battery-type generator. [0004] In order to achieve the abo...
