In this embodiment, the heat conducting member 200 is made of metal and includes a heat conducting rod and a diffusion plate, the cross-sectional area of the diffusion plate is equal to the inner cross-sectional area of the housing 210, and the heat conducting rod is fixed to the bottom surface of the diffusion plate and inserted into the module body 100 after passing through the bottom end of the housing 210.

In order to ensure the connection stability between the reminder unit 200 and the module body 100, glue may be applied to the contact surface between the reminder unit 200 and the module body 100, so as to stably adhere the reminder unit 200 to the module body 100.

The baffle 230 is rotatably installed on the inner side surface of the housing 210 near the upper end, and the cross-sectional area of the baffle 230 is equivalent to the inner cross-sectional area of the housing 210, so that the baffle 230 can divide the interior of the housing 210 into two completely independent spaces when in a horizontal state.

In this embodiment, the number of the baffles 230 is two, two baffles 230 are installed at the same height inside the housing 210, and one ends of the two baffles 230, which are far away from the connection with the housing 210, contact each other. In order to improve the air blocking performance of the two baffles 230, a sealing rubber strip is mounted on the end surface of one end of the two baffles 230, which is in contact with each other.

In other embodiments, the number of the baffles 230 may be one.

Sound production subassembly 240 installs in the inside upper end of shell 210, just there is the certain distance between sound production subassembly 240 and the baffle 230, makes baffle 230 can the certain angle of upwards rotating, sound production subassembly 240 has air inlet and gas outlet, and the air gets into fast from the air inlet, when flowing from the gas outlet, sound production subassembly 240 sends sound promptly.

In order to increase the pressure that can be maintained under the baffle 230 when heated, an elastic member is installed on the baffle 230, and the elastic member provides an elastic force for the baffle 230 to rotate downward. In one embodiment, the elastic member is a torsion spring installed at a connection between the barrier 230 and the housing 210. In another embodiment, the elastic member is a tension spring, and two ends of the tension spring are respectively connected to the bottom surface of the baffle 230 and the inner side surface of the housing 210.
