In addition, the gas alarm can be fixed on the wall surface through hanging rings or bonding and other modes.

The control chip of the circuit board 5 of the gas alarm is also connected with an audible and visual alarm, and the audible and visual alarm receives the designation of the control chip and can send out a red light and alarm sound to remind a user in a house that gas is leaked. The control chip is also connected with a communication circuit, and the gas alarm realizes the communication function with the mobile equipment through the communication circuit. If the user closes the door in a far room, the user is difficult to hear the alarm sound in the room with gas leakage under the condition of good sound insulation effect, so the embodiment provides the binding function of the gas alarm and the mobile device, and after the binding, the gas alarm not only can control the audible and visual alarm to give an alarm, but also can send alarm information to all bound mobile devices through the communication circuit when detecting the gas leakage. When a user plays a mobile phone or a tablet personal computer in a room, the alarm information can be received, so that the user can find out that gas leakage occurs in the room in time, and corresponding measures are taken. When the user is outside the house, for example, when a company uses a notebook computer to work, the alarm information sent by the gas alarm can be received by the notebook computer, and after knowing that gas leakage occurs at home, the user can timely select to alarm for help or inform other family members at home or nearby to immediately take corresponding measures.

The gas alarm with the lighting function provided by the embodiment has the following specific working principle:

the gas detection sensor in the gas alarm detects the specified gas concentration in a room, such as carbon monoxide concentration, in real time through the gas hole in the shell of the gas alarm.

When the detected specified gas concentration reaches the threshold value, the control chip of the gas alarm sends an alarm instruction to the audible and visual alarm to send out a red light alarm and a warning sound, and turns on the lamp bead of the illuminating lamp. Meanwhile, the control chip of the gas alarm also can send alarm information to the mobile equipment bound by the user to inform the user to take corresponding countermeasures in time.

When a room with gas leakage is in the dark or in the environment with insufficient light, the lighting assembly of the gas alarm is controlled by the internal control chip to be lightened, and the lighting light emitted by the lighting lamp is enhanced after being emitted by the concave cavity to provide enough light. After entering a room with gas leakage, a user can find a gas source and cut off the gas source according to light provided by a lighting assembly of the gas alarm without searching for a light switch in the room.

The gas alarm with the lighting function provided by the embodiment has the advantages that the structure is simple, the practicability is high, the lighting assembly is arranged in the concave cavity, and the service life of the lighting assembly is longer. The illuminating assembly forms a concave cavity through the illuminating lamp fixing plate and the alarm shell, and the concave cavity reflects light emitted by the LED illuminating lamp and then transmits the light out, so that the illuminating brightness of the LED lamp is enhanced, and sufficient light is provided in an environment with insufficient light. When the light illumination is not ideal or gas leakage occurs during night, users do not need to additionally turn on the lamp for illumination when taking emergency measures such as cutting off the gas source, opening windows for ventilation and the like. The lighting assembly of the alarm provides enough brightness, and a user can find and cut off the air source in time by means of the brightness provided by the lighting assembly, so that precious time is won for the user.
