The operating principle of the present invention is now explained as follows: when an Alzheimer patient wears the first device body 1, the conical shell 71 is placed on the inside of the coat, the first device body 1 is placed on the outside of the coat, and then the surface of the first device is The limit pin 11 penetrates the clothes, and the limit pin 11 is inserted into the socket on the surface of the cone shell 71 and the cone seat 72. When the limit pin 11 is inserted between the three limit balls 10, the limit pin 11 11 will squeeze and push the limit ball 10 to the left, causing the three limit balls 10 to move to the left at the same time. Since the outer wall of the conical shell 71 is a cone, when the three limit balls 10 move to the left together, the three limit balls 10 will move to the left at the same time. The gap between the limiting balls 10 will expand, and the limiting pin 11 can be smoothly inserted between the three limiting balls 10. The limiting balls 10 can move in the spherical hole 9, but the limiting balls 10 cannot pass through the spherical hole 9. The hole 9 passes through the cone seat 72, and when there is no limit pin 11 between the three limit balls 10, the three limit balls 10 will resist each other and will not cause the limit ball 10 to pass through the spherical hole 9. When the groove 12 on the surface of the limiting pin 11 is located between the three limiting balls 10, part of the three limiting balls 10 will get stuck into the groove 12 under the action of the extrusion force. The tapered shell 71 and the limiting pin 11 can be fixed, so that the first device body 1 can be fixed on the outside of the patient's coat. When the patient pulls the first device body 1 or other items accidentally pull the first device body 1, the limit The position pin 11 will pull the three limit balls 10 to move to the right together.

The pressure is more reliable, thereby preventing the first device body 1 from being separated from the patient's clothes. When it is necessary to remove the first device body 1, the family member can take the equipped strong magnet and place it on the left side of the conical shell 71. The strong magnet will Attracting the permanent magnet ring 13 to move, the permanent magnet ring 13 drives the cone seat 72 and the limiting balls 10 to move to the left together. When the three limiting balls 10 move to the left, the gaps between the three limiting balls 10 will increase, so that the limiting pin 11 can be pulled out and the first device body 1 is removed;

After the first device is put on, the top ring 16 will be squeezed by the cone shell 71 and move to the right. The top ring 16 drives the ring plate 15 to move to the right through the cross pin 142, so that the ring plate 15 and the two conductive blocks 17 are separated. , thereby disconnecting the two conductive blocks 17. After the first device body 1 is installed, the first device body 1 can be controlled to be energized through an external button. When the limit pin 11 is disconnected due to corrosion or other reasons, causing After the first device body 1 is detached, the top ring 16 will be released from the position, and the ring plate 15 will move to the left under the tension of the spring, so that the ring plate 15 contacts the upper and lower conductive blocks 17, and the lower conductive block 17 It is electrically connected to the first micro power supply 18, and the upper conductive block 17 is electrically connected to the buzzer 4 and the PLC controller. After the ring plate 15 comes into contact with the upper and lower conductive blocks 17, the buzzer 4 will be powered on first.

Five seconds after the micro air pump 21 and the second solenoid valve 26 are powered on, the first device body 1 also falls to the ground. After five seconds, the PLC controller controls the micro air pump 21 to stop working, and transmits current to the first solenoid valve 25 to connect the lower tube 23 and the cooling chamber 53, and the gas inside the protective air bag 191 can flow along the lower tube 23 , the upper tube 22 is transported to the cooling chamber 53 for discharge to avoid affecting the heat dissipation performance of the electronic components on the surface of the circuit board 20, and the surface of the circuit board 20 is provided with a temperature sensing element.
