When it is detected that the gas concentration exceeds the standard, it can also remind the user to reduce the safety hazards caused by gas leakage.

[0046] The alarm mechanism includes an exit detection unit, an alarm unit, a transmission unit and a main control unit 5. The exit detection unit, the alarm unit and the transmission unit are all electrically connected to the main control unit 5. When the flame detection mechanism detects that the gas cooker is working and the exit detection unit detects that the user is leaving the house, the main control unit 5 controls the alarm unit to sound an alarm to remind the user that the gas cooker is in use, thereby effectively reducing potential safety hazards. In this embodiment, the alarm mechanism also includes a shell, and the shell includes an upper shell 21 and a lower shell 22. The upper shell 21 is snapped onto the lower shell 22. A circuit board 23 is disposed in the lower shell 22. The exit detection unit, the alarm unit, the transmission unit and the main control unit 5 are all disposed on the circuit board 23.

In this embodiment, the mounting plate 221 is fixedly bonded to the door by bonding. In fact, it can also be fixedly connected to the door by bolts or the like.

[0056] The working principle of this utility model:

[0057] The flame sensor 11 detects the working state of the gas cooker. When the flame sensor 11 detects that the gas cooker is working:

[0058] When the user goes out and approaches the door, the infrared sensor 41 detects the user's approach and sends a signal that the user has approached to the main control unit 5. The main control unit 5 determines whether a vibration signal is received.

[0059] If the user opens the door, the vibration sensor 42 detects the vibration signal and sends a vibration signal to the main control unit 5, then the main control unit 5 controls the speaker 61 and the strobe light 62 to work, the speaker 61 plays the preset audio to give the user a voice reminder, and the strobe light 62 flashes to give the user a light stimulation reminder.

[0060] If the user does not open the door, the main control unit 5 does not receive the vibration signal, and the alarm remains silent.

[0061] When the user returns home, the alarm remains silent because the vibration sensor 42 is triggered first and then the infrared sensor 41.

[0062] The above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
