[0027] During use, dust and oil stains easily accumulate inside the ventilation detection hole 13 after a long period of time. If it is necessary to clean the ventilation detection hole 13, the protective cover 11 can be loosened and removed. Then, the control panel 12 can be operated to control the mini electric push rod 31 to work. Under the action of the mini electric push rod 31, the push plate 34 is pushed to slide along the guide rod 32, which drives the push column 33 to move synchronously, so that the push column 33 is inserted into the ventilation detection hole 13 to squeeze out and clean the oil stains inside the ventilation detection hole 13, so as to realize the function of cleaning oil stains and dust inside the ventilation detection hole 13 of the gas alarm.

[0028] Working principle: In use, firstly, the mounting plate 211 is fixed to the wall with screws. Then, the outer shell 1 is placed on one side of the mounting plate 211, so that the annular groove 23 fits onto the surface of the positioning ring 212. At this time, the annular groove 23 presses against the locking block 213, causing the locking block 213 to retract into the receiving groove 214. Then, the outer shell 1 is rotated, causing the outer shell 1 to drive the locking hole 22 to rotate synchronously. When the locking hole 22 rotates to the side of the locking block 213, the locking block 213 is locked into the inside of the locking hole 22 under the elastic force of the extension spring 215, automatically locking the outer shell 1 to realize the function of easy installation of the gas alarm, thereby improving the convenience of gas alarm installation.

[0029] During use, gas enters the inner side of the partition frame 16 through the ventilation detection hole 13, and the gas concentration in the gas is monitored by the gas sensor 17. The result is transmitted to the control panel 12. If the gas concentration is high, the control panel 12 controls the buzzer 15 to work and sound an alarm, so as to realize the gas alarm function of the gas alarm.

[0030] Over time, dust and oil stains easily accumulate inside the ventilation detection hole 13. If it is necessary to clean the ventilation detection hole 13, the protective cover 11 can be loosened and removed. Then, the control panel 12 can be operated to control the mini electric push rod 31. Under the action of the mini electric push rod 31, the push plate 34 is pushed to slide along the guide rod 32, which drives the push column 33 to move synchronously. The push column 33 is inserted into the ventilation detection hole 13 to squeeze out and clean the oil stains inside the ventilation detection hole 13. This realizes the function of cleaning the oil stains and dust inside the ventilation detection hole 13 of the gas alarm, thereby avoiding the phenomenon of blockage of the ventilation detection hole 13 when the gas alarm is used, and finally completing the use of the gas alarm.
