According to some embodiments of the present invention, as shown in fig. 3, the housing 10 may have a through hole structure 16, which enables the interior of the housing to communicate with the outside, so that the interior of the smoke alarm apparatus 100 is consistent with the environmental condition of the outside, and thus the smoke sensor 13 can accurately detect the smoke concentration of the outside in real time, and also enables the temperature sensor 14 to accurately detect the outside temperature in real time. When the outside smoke concentration and the outside smoke temperature reach the alarm values, the control circuit board 15 can control the alarm device 20 to alarm according to the detection information of the smoke sensor 13 and the temperature sensor 14, so that the early warning accuracy of the smoke alarm device 100 is improved.
According to some embodiments of the invention, as shown in fig. 3, the housing 10 may be provided with a mounting 17 and/or a magnetic attraction 18, i.e. the housing 10 may be provided with a mounting 17, or the housing 10 may be provided with a magnetic attraction 18, or the housing 10 may be provided with a mounting 17 and a magnetic attraction 18. The mounting 17 may be provided with a threaded bore through which the smoke alarm apparatus 100 may be fitted by means of a bolt co-operation to mount it indoors. The magnetic attraction member 18 may be attracted to a metal member within the chamber to enable the smoke alarm apparatus 100 to be installed within the chamber. The smoke alarm device 100 can be installed on a roof, a wall and the like by arranging the mounting seat 17 and the magnetic attraction piece 18 on the shell 10, so that the smoke alarm device 100 can detect the indoor situation and alarm timely, an indoor user can escape from a fire scene in advance, accident risk and loss are reduced, and the security of the smoke alarm device 100 to personal safety is improved.
According to some embodiments of the present invention, the housing 10 may be provided with an indicator light, which may be normally on when the smoke alarm apparatus 100 is operating normally, and off when the smoke alarm apparatus 100 is not powered or damaged, to prompt the user to replace the battery or replace the smoke alarm apparatus 100 with a new one, so as to avoid the alarm device 20 from being unable to alarm when the smoke alarm apparatus 100 is powered off or damaged, thereby reducing accident risk and loss.
