[0001] The utility model relates to the technical field of alarms, and in particular to an Internet of Things alarm device. Background Art

[0002] With the increase in the use of fire and electricity in society, the frequency of fires is getting higher and higher. Once a fire occurs, it is easy to encounter unfavorable factors such as untimely firefighting, lack of fire-fighting equipment, panic of people on the scene, and slow escape, which ultimately leads to significant loss of life and property. In order to improve safety in the event of a fire, it is usually necessary to install a fire alarm in the building;

[0003] At present, common alarms mainly rely on sensors to control the buzzer to sound the alarm. However, this type of alarm mainly relies on power supply during operation. In daily use, this type of alarm needs to replace the built-in power supply regularly. Once the built-in power supply is exhausted, the alarm device will not work properly. In the event of a short circuit causing a fire, the alarm cannot be sounded in time, which may lead to delays in escape and cause injuries to people. Therefore, it is necessary to propose an auxiliary device that can still work and provide an alarm signal when the built-in power supply is exhausted, so as to assist the electric alarm to achieve a better alarm effect.

[0025] The fuse 4 and the wire 2 are connected in parallel circuit inside the main board 1, so that the current passing through the fuse 4 is consistent with the current inside the wire 2, so that when the current inside the wire 2 increases, the current inside the fuse 4 will also increase, so that the fuse 4 melts. The lower end of the fuse 4 is fixedly connected to a gravity block 7, and the left end of the gravity block 7 is spirally driven with a spiral rod 9. The gravity block 7 falls by itself, so that the spiral rod 9 rotates through the spiral transmission, and the lower end of the gravity block 7 is fixedly connected to a spring 8, and the spring 8 runs through a limit rod 22. The limit rod 22 is used to limit the spring 8 when it is contracted to prevent the spring 8 from bending. The spring 8 provides additional power for the gravity block 7 to fall;

[0026] A support block 10 is fixedly connected to the lower end of the inner wall of the cavity, and the upper end of the support block 10 is fixedly connected to the lower end of the spring 8. The support block 10 is used to support the spring 8 for telescopic deformation.

A support frame 11 is fixedly connected to the lower end of the main board 1, and a whistle 12 is fixedly connected to the lower end of the support frame 11. The whistle 12 is used to emit a chirping sound to warn. A fan 18 is installed at the input end of the whistle 12. The right end of the fan 18 is fixedly connected to the transmission assembly. The fan 18 is used to provide an inlet airflow so that the whistle 12 can emit a chirping sound to remind the user;

[0027] The transmission assembly includes a first column gear 19, the upper end of which is fixedly connected to the lower end of the screw rod 9, and the first column gear 19 is driven to rotate by the rotation of the screw rod 9, the first column gear 19 is meshedly connected with the second column gear 20, the second column gear 20 is rotatably connected to the lower end of the main board 1, the second column gear 20 is meshedly connected with the third column gear 21, the second column gear 20 is used to connect the first column gear 19 and the third column gear 21 so that the angular velocity between the two is increased, the left and right sides of the lower end of the main board 1 are respectively rotatably connected with the roller 14 and the rotating shaft 23, the rotating shaft 23 and the roller 14 are jointly sleeved with the belt 13, the lower end of the rotating shaft 23 is fixedly connected to the upper part of the third column gear 21, and the rotating shaft 23 is driven to rotate by the third column gear 21 so that the belt The belt 13 can rotate, and the belt 13 rotates to drive the roller 14 to rotate. The lower end of the roller 14 is fixedly connected to a first bevel gear 15, so that the roller 14 rotates to drive the first bevel gear 15 to rotate. The upper end of the roller 14 is rotatably connected to the lower end of the main board 1. The first bevel gear 15 is meshed and connected to a second bevel gear 16. The first bevel gear 15 rotates to drive the second bevel gear 16 to rotate.

[0028] The mainboard 1 is installed with an Internet of Things wireless module 3, which is used to send wireless signals so that the user can receive early warning information. The gear ratio of the first column gear 19 and the third column gear 21 is 8:1, so that the rotation time of the third column gear 21 is increased, thereby prolonging the sound of the whistle 12. A dust cover 5 is fixedly connected to the lower end of the mainboard 1, and the dust cover 5 is used to prevent dust from entering the transmission component, thereby ensuring the linkage and smoothness of the transmission component when working. A loudspeaker 6 is installed on the left side of the dust cover 5, and the loudspeaker 6 is used to amplify the whistle sound, thereby increasing the range of transmission of the sound and expanding the warning range of the alarm.

[0029] Working principle: When the alarm is working normally, the spring 8 is in a stretched state. When a short circuit occurs in the line, the current of the fuse 4 increases, causing the temperature of the fuse 4 to rise and melt the fuse 4, thereby the fuse 4 breaks and causes the gravity block 7 to fall. Then the spring 8 provides additional pulling force to force the gravity block 7 to fall better. The falling of the gravity block 7 drives the spiral rod 9 to rotate, thereby the spiral rod 9 drives the first column gear 19 to rotate, thereby the first column gear 19 drives the third column gear 21 to rotate through the second column gear 20, and the rotation of the third column gear 21 drives the third column gear 21 to rotate. The rotating rod is driven to rotate, and the rotation of the rotating rod drives the belt 13 to rotate, so that the belt 13 drives the roller 14 to rotate, and the rotation of the roller 14 drives the first bevel gear 15 to rotate, and the first bevel gear 15 drives the second bevel gear 16 to rotate through the meshing motion, so that the second bevel gear 16 drives the fan 18 to rotate through the rotating rod 17. At this time, the fan 18 starts to blow gas into the internal cavity of the whistle 12, and the whistle 12 immediately emits a chirping sound, and the sound waves are then transmitted through the loudspeaker 6 for enhanced transmission, so that the alarm emits a chirping sound to remind the surrounding people.
