Problems solved by technology
[0003] In the prior art, the power of the battery itself is limited, and it cannot supply power to the smoke alarm for a long time. For this, it is necessary to replace the battery technically by the staff
[0004] The above-mentioned existing technical solutions have the following defects: in actual situations, various reasons such as wet weather or PCBA circuit board aging will cause leakage, which will greatly easily cause the installer to replace the battery. , When the battery hardware is accidentally touched, the staff will get an electric shock. That is, if the user replaces the battery, if there is a leakage in the smoke alarm, there will be a high risk of electric shock and casualties during the battery replacement process.

Embodiment Construction
[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0048] Such as figure 1 As shown, an anti-shock smoke alarm is used to detect smoke concentration, which includes a housing 1 and a mounting device 3, wherein the housing 1 includes a lower housing 12 and an upper housing 11, and the upper housing 11 and the lower housing 12 pass through The connection is made in a buckle manner, and the mounting device 3 slides and engages with the lower shell 12 . By rotating the lower shell 12 to make the shell 1 rotate a predetermined number of times, the shell 1 can be detached from the mounting device 3 . When the smoke alarm needs to be installed on the ceiling, the installation device 3 is first installed on the ceiling by screws. At this time, the installation device 3 is facing the ceiling, and the housing 1 is facing the ground, such as figure 2 As shown, the high-voltage line is inserted into the high-voltage pl...

The invention relates to an anti-electric shock smoke alarm and its use method, and relates to the technical field of smoke alarms. It includes a housing, and a toggle switch device is arranged in the housing, and the toggle switch device is slidably connected in the housing. , and is electrically connected with the PCBA circuit board in the housing, the housing is detachably installed with a mounting device, the mounting device rotates with the housing and slides with the toggle switch device, when the forward or reverse rotation When the housing is installed, the installation device indirectly causes the toggle switch device to disconnect or connect the high voltage power supply to the PCBA circuit board by restricting the position of the toggle switch device. The invention has the effect of preventing electric shock.
Description
technical field [0001] The invention relates to the technical field of smoke alarms, in particular to an electric shock-proof smoke alarm and a use method thereof. Background technique [0002] At present, the smoke alarm monitors the concentration of smoke to prevent fires. It is usually installed on the ceiling by screws. The smoke alarm includes an upper shell and a lower shell connected by screws. The lower shell generally includes a PCBA circuit board and a battery. The connecting wire is electrically connected to the PCBA circuit board, and a strong current access port for high-voltage wires (mains) is provided on the upper shell, and the high-voltage wires are connected to the PCBA circuit board through the strong current access port. When the smoke alarm is working, the high-voltage wire supplies power to the smoke alarm. When the power fails, the high-voltage wire stops supplying power to the smoke alarm. At this time, the battery supplies power to the smoke alarm i...
