As shown in the figure, the household earthquake alarm includes a columnar insulating tank 1, a conductive ring 2 is suspended inside the columnar insulating tank 1, a conductive cone 3 is suspended below the conductive ring 2, and a conductive ring 2 and a conductive cone are suspended. The suspension wires of 3 are all conductive wires, which are respectively the first conductive wire 4 and the second conductive wire 5, the second conductive wire 5 passes through the middle part of the conductive ring 2, and the inner wall of the columnar insulating tank body 1 adjacent to the conductive ring 2 is provided with a second A conductive ring wall 6, the inner wall of the cylindrical insulating tank 1 adjacent to the conductive cone 3 is provided with a second conductive ring wall 7, and the first battery pack 801 and the first battery pack 801 are connected in series between the first conductive wire 4 and the second conductive wire 5. The first alarm 802, the second battery pack 901 and the second alarm 902 are connected in series between the first conductive wire 4 and the first conductive ring wall 6, and the second conductive wire 5 and the second conductive ring wall 7 are connected in series A third battery pack 1001 and a third alarm 1002 are connected. In this way, when an earthquake comes, when the household earthquake alarm shakes with the earthquake, the conductive ring 2 and the second conductive wire 5, or the conductive ring 2 and the first conductive ring wall 6, or the conductive cone 3 and the second conductive ring wall 7 If they touch together during shaking, a loop can be formed, and the first alarm 802 or the second alarm 902 or the third alarm 1002 in the loop can be triggered, so as to achieve the purpose of reminding people in time. Wherein, the mass of the conductive ring 2 is m1, the mass of the conductive cone 3 is m2, when the second conductive wire 5 touches the conductive ring 2, the displacement height of the conductive cone 3 is h1, and when the conductive cone 3 touches the second conductive ring wall 7, The displacement height of the conductive cone 3 is h2, and when the conductive ring 2 touches the first conductive ring wall 6, the displacement height of the conductive ring 2 is h3.

According to the gravitational potential energy formula Ep=mgh, Ep1=m1gh1, Ep2=m2gh2, Ep3=m3gh3, where g is the gravity coefficient, which is a fixed value. In this way, during specific implementation, m2h1<m2h2<m1h3 is set, that is, Ep1<Ep2<Ep3, that is, the first magnitude<the second magnitude<the third magnitude, so that the conductive ring 2 and the second conductive wire 5, or conductive The circuit formed by contacting the ring 2 and the first conductive ring wall 6, or the conductive cone 3 and the second conductive ring wall 7 during shaking can correspond to three different levels of earthquake magnitudes, and the first alarm is also set in the three levels of circuits.
