[0014] 2. This utility model, by setting up a backup power supply component, allows the user to turn on the battery in the event of a power outage. The battery's internal power is then transferred to the inverter via wires, which converts the battery's 12V power to 220V. The converted 220V power is then transmitted to the detection device via the auxiliary power line, thus enabling the detection device to continue operating even in the event of a power outage.

[0015] 3. This utility model, by setting up a power failure self-opening component, allows installers to connect the detection end of the power failure sensor to the indoor power supply via a wire.

A battery 72 is fixedly installed on the left side of the bottom inside the control box 6, and the battery 72 is electrically connected to the inverter 71 through wires.

[0023] As a technical optimization of this utility model, by setting up a backup power supply component 7, when a power outage occurs, the user turns on the storage battery 72, so that the power inside the storage battery 72 is transferred to the inverter 71 through the wire. The inverter 71 converts the 12V power of the storage battery 72 into 220V, and the converted 220V power is transferred to the detection device 1 through the auxiliary power line 5 to power the device, so that the detection device 1 can continue to be used in the event of a power outage.

[0024] refer to Figure 3The power failure self-opening component 8 includes a power failure sensor 81, which is fixedly installed on the right side of the rear side inside the control box 6. The detection end of the power failure sensor 81 is electrically connected to the indoor power supply through a wire. The main controller 82 is fixedly installed on the left side of the rear side inside the control box 6. The signal receiving end of the main controller 82 is electrically connected to the signal output end of the power failure sensor 81 through a wire. The signal output end of the main controller 82 is electrically connected to the battery 72 through a wire.

[0025] As a technical optimization of this utility model, by setting a power failure self-opening component 8, the installer can connect the detection end of the power failure sensor 81 to the indoor power supply through a wire. When a power failure occurs, the output end of the power failure sensor 81 will transmit the signal to the main controller 82 through the wire, so that the main controller 82 can analyze the transmitted data. After the analysis is completed, the signal output end of the main controller 82 will turn on the battery 72 through the wire, so that the backup power supply component 7 can supply power to the detection device 1, reducing the need for manual intervention by the user.

[0026] refer to Figure 2 A warning light 9 is fixedly installed on the left side of the top of the control box 6. The warning light 9 is electrically connected to the signal output terminal of the main controller 82 through a wire.

[0027] As a technical optimization of this utility model, by setting a warning light 9, when the main controller 82 turns on the battery 72, its signal output terminal will turn on the warning light 9 through the wire, so that the warning light 9 emits a red flashing light to remind the user that there is a power outage indoors, so that the user can observe whether the power outage self-turn-off component 8 is operating normally.

[0028] refer to Figure 2 A buzzer 10 is fixedly installed on the right side of the top of the control box 6. The buzzer 10 is electrically connected to the battery 72 via a wire.

[0029] As a technical optimization of this utility model, a buzzer 10 is set up so that the buzzer 10 is electrically connected to the storage battery 72 through a wire. When the storage battery 72 is turned on, it will supply power to the buzzer 10, so that the buzzer 10 will emit a buzzing sound to strengthen the power outage reminder to the user.

[0030] refer to Figure 1 The other end of the main power cord 4 is connected to the indoor socket via a plug.

[0031] As a technical optimization of this utility model, the other end of the main power cord 4 is connected to the indoor socket through a plug, thereby enabling the indoor socket to provide stable power for the daily use of the detection device 1.

[0032] refer to Figure 2Warning light 9 uses a built-in power supply.

[0033] As a technical optimization of this utility model, by adopting a warning light 9 with a built-in power supply, the warning light 9 does not consume the power of the storage battery 72 when a power outage occurs indoors.

[0034] The working principle and usage process of this utility model are as follows: First, the installer fixes the control box 6 and the detection device 1 to the indoor wall. Then, the other end of the main power line 4 is connected to the indoor socket via a plug, ensuring a stable power supply for the daily use of the detection device 1. Next, the installer connects the detection end of the power failure sensor 81 to the indoor power supply via a wire. When a power failure occurs, the output end of the power failure sensor 81 transmits a signal to the main controller 82 via a wire. The main controller 82 analyzes the transmitted data. After analysis, the signal output end of the main controller 82 turns on the battery 72 via a wire, allowing the battery's charge to be transmitted to the inverter 71. The inverter 71 converts the 12V power from the battery 72 to 220V, and the converted 220V power is transmitted to the detection device 1 via the auxiliary power line 5. This ensures that the detection device 1 can continue to operate even during a power failure, guaranteeing user safety.

[0035] In summary, this combustible gas alarm equipped with a backup power supply, by setting up an auxiliary power line 5, connects the auxiliary power line 5 to the backup power supply component 7. In the event of a power outage, the backup power supply component 7 will provide a stable power supply to the detection device 1 through the auxiliary power line 5, preventing the detection device 1 from becoming unusable due to power failure. This solves the problem that existing household gas alarms often lack a backup power supply, causing them to malfunction when a sudden power outage occurs, thus affecting user safety.
