Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 and Figure 2A manual fire alarm device comprises a device body 1 and an alarm button 18 on the device body 1, a reset device 17 is arranged on the device body 1, and the reset device 17 is used to reset the alarm button 18, a buffer groove 2 is arranged around the device body 1, and shock-absorbing springs 4 are fixedly installed at the four corners of the buffer groove 2, one end of the shock-absorbing spring 4 is fixedly connected with a buffer plate 5, and one end of the buffer plate 5 is inserted into the buffer groove 2, a protective cover 6 is hingedly connected to the buffer plate 5, and the protective cover 6 covers the device body 1, and the four corners of the buffer groove 2 are fixedly installed There is a damper 3, and one end of the damper 3 passes through the inside of the shock absorbing spring 4 and is fixedly connected to the buffer plate 5. The manual fire alarm host and the alarm button 18 communicate through optical fiber. The alarm button 18 is connected in a passive manner. When the manual fire alarm device needs to be used, by pressing the alarm button 18, the optical fiber loop is interrupted, and the host determines the alarm position according to the street information in the loop and the manual alarm button coding information, and emits red light to the interrupted loop (similar to the principle of a red light pen), and the emitted red light is displayed on the pressed manual alarm button (as an alarm press confirmation indicator) , notify people to evacuate the building in time to ensure people's life safety. After the alarm is lifted, the alarm button 18 is reset by the person through the key. After the host detects that the circuit is normal, the alarm is lifted and the red light is stopped to the circuit. However, in daily life, the alarm device may be accidentally hit by external force, resulting in the problem of false touch or damage to the alarm device. When the alarm device is protected, it is convenient to protect the alarm device by installing a buffer plate 5. First, when the device body 1 is hit by the outside world, it will first hit the buffer plate 5. The buffer plate 5 will compress the shock absorbing spring 4 and the damper 3 to move slowly into the buffer groove 2 to reduce the impact force on the device body 1. At the same time, the shock absorbing spring 4 will absorb part of the impact force and slow down the impact force on the buffer plate 5. After the impact force dissipates, the buffer plate 5 will be reset by the elastic force of the shock absorbing spring 4, which reduces the risk of damage to the fire alarm device and increases the service life of the manual fire alarm device. When the fire alarm device needs to be used, the alarm button 18 on the device body 1 is triggered by opening the protective cover 6, which reduces the probability of false touch of the manual fire alarm device.

[0023] See also Figure 2 A soft rubber pad 7 is provided at one end of the buffer plate 5, and the buffer plate 5 contacts the bottom of the buffer groove 2 through the soft rubber pad 7. The soft rubber pad 7 has good toughness and elasticity. When the buffer plate 5 contacts the buffer groove 2, the soft rubber pad 7 buffers the contact surface thereof to prevent the buffer plate 5 from colliding violently with the buffer groove 2.

[0024] See also Figure 1 , Figure 3 and Figure 4The bottom of the device body 1 is provided with a storage groove 8, and a return spring 9 is symmetrically installed in the storage groove 8, and the return spring 9 is fixedly installed in the storage groove 8. A carrying box 10 is slidably arranged in the storage groove 8, and one end of the carrying box 10 is fixedly connected to the return spring 9. A dehumidifier 11 is placed in the carrying box 10, and a pull ring 14 is fixedly installed on the carrying box 10. The pull ring 14 is used to pull the carrying box 10 out of the storage groove 8. When the device body 1 is moisture-proof, the dehumidifier 11 is provided to facilitate moisture-proofing of the device body 1. First, the storage slot 8 is connected with the interior of the device body 1, and the moisture in the device body 1 is adsorbed by the dehumidifier 11 placed in the carrier box 10, and then the carrier box 10 is pulled out of the storage slot 8 through the pull ring 14. The dehumidifier 11 is replaced regularly. After replacement, the pull ring 14 is released, and the stretched reset spring 9 will drive the carrier box 10 to re-enter the storage slot 8 during reset. The dehumidifier 11 that is replaced regularly ensures that the fire alarm device is not disturbed by the humid environment, thereby improving the stable use of the manual fire alarm device.

[0025] See also Figure 4 A slide groove 12 is symmetrically arranged in the storage groove 8, a slider 13 is slidably connected in the slide groove 12, and the slider 13 is fixedly installed at the bottom end of the carrier box 10. The slider 13 drives the carrier box 10 to move in the slide groove 12, which limits the carrier box 10 and further increases the stability of the carrier box 10.

[0026] See also Figure 4 A groove 15 is arranged around one end of the storage groove 8, a sealing ring 16 is arranged around one end of the carrying box 10, and the carrying box 10 drives the sealing ring 16 to engage in the groove 15. The carrying box 10 drives the sealing ring 16 to engage in the groove 15, so as to seal the edge of the storage groove 8 to prevent external water vapor from entering the device body 1 through the edge gap of the storage groove 8.

[0027] Working principle: when the alarm device is protected, the buffer plate 5 is installed to facilitate the protection of the alarm device. First, when the device body 1 is impacted by the outside world, it will first collide with the buffer plate 5. The impact of the buffer plate 5 will compress the shock-absorbing spring 4 and the damper 3 and slowly move them into the buffer groove 2, thereby reducing the impact force on the device body 1. At the same time, the shock-absorbing spring 4 will absorb part of the impact force and reduce the impact force on the buffer plate 5. After the impact force dissipates, the buffer plate 5 will be reset by the elastic force of the shock-absorbing spring 4, thereby reducing the risk of damage to the fire alarm device and increasing the service life of the manual fire alarm device. When the fire alarm device needs to be used, the protective cover 6 is opened to press the alarm button 18 on the device body 1. The dehumidifier 11 is provided to facilitate moisture-proofing of the device body 1. First, the storage groove 8 is communicated with the inside of the device body 1. The moisture in the device body 1 is adsorbed by the dehumidifier 11 placed in the carrier box 10. Then, the carrier box 10 is pulled out of the storage groove 8 by the pull ring 14. The dehumidifier 11 is regularly replaced. After replacement, the pull ring 14 is released. The stretched reset spring 9 will drive the carrier box 10 to re-enter the storage groove 8 when resetting. The regularly replaced dehumidifier 11 ensures that the fire alarm device is not disturbed by the humid environment, thereby improving the stable use of the manual fire alarm device.
