Detailed Description

In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.

Referring to fig. 1-4, the intelligent leakage alarm device of the present invention comprises a box body 10, wherein the box body 10 has:

an alarm mechanism 30 mounted on the box body 10 and provided with an independent power supply 50; and

the signal trigger mechanism 20 is conducted with an internal circuit of the box body 10 through a conductive wire 40, and comprises an installation part 21, a first contact part 22 and a second contact part 23 which are arranged in the installation part 21 and magnetically attracted in an energized state, a trigger part 25 arranged at the other end of the second contact part 23, and an elastic part 24 in a compressed state in the energized state, wherein the elastic part 24 can drive the trigger part 25 to start a switch button of the alarm mechanism 30 in a power-off state.

Specifically, the alarm mechanism 30 includes a touch switch 35, a circuit board 34, a buzzer 33, an alarm lamp 32, and a transparent outer cover 31, wherein the circuit board 34 is connected to the touch switch 35, the buzzer 33, and the alarm lamp 32 through a conductive wire 40, the touch switch 35 is connected to an independent power source 50 through a conductive wire 40, and a contact reed 350 of the touch switch 35 faces the trigger portion 25.
