[0002] The fire alarm controller is the heart of the automatic fire alarm system. It can power detectors and has the following functions: receiving fire signals and activating the fire alarm device. This device can also be used to indicate the location of the fire and record relevant information. It can initiate fire alarm signals through the fire alarm transmitter or activate automatic fire extinguishing equipment and fire linkage control equipment through the automatic fire extinguishing control device. It can automatically monitor the correct operation of the system and issue audible and visual alarms for specific faults. In order to monitor whether a fire has occurred in real time, the fire alarm controller must be running at all times. A Chinese patent discloses a fire alarm controller (authorization publication number CN218996116U). This patented technology discloses a fire alarm controller including a housing and a fire alarm controller body. A limit plate is fixed to one side of the housing, and the fire alarm controller body is located on the side of the limit plate.

Numerous modifications and variations will be apparent to those skilled in the art. The examples are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0028] For examples, see Figures 1 to 6 In this embodiment, a fire alarm controller is provided, comprising: an embedded box 1; a mounting frame 5 is integrally fixed to one end of the front side of the embedded box 1, and a fire alarm structure 2 for fire early warning is provided inside the embedded box 1;

[0029] The fire alarm structure 2 is embedded in the inner wall of the room through the embedded box 1, and the fire alarm structure 2 includes a fire alarm body 201 movably arranged on the inner side of the embedded box 1, and a screw block 202 is fixed on the top of the fire alarm body 201, and a reciprocating screw rod 203 is spirally driven inside the screw block 202.

[0030] One end of the reciprocating screw 203 is connected to a servo motor 204 mounted on the inner wall of the embedded box 1. The servo motor 204 is used to actively rotate the reciprocating screw 203. The embedded box 1 has an internal adjustment slot 3 defined within it. A spur plate 205, fixedly mounted on the outer wall of the fire alarm body 201, is movably positioned within this slot. This spur plate 205 engages a spur gear 207, which is fixedly mounted at its center with a shaft 206, which is rotatably mounted on the inner wall of the internal adjustment slot 3.

[0031] A bevel gear 1 208 is fixedly mounted on the outer wall of the shaft 206. This bevel gear 1 208 meshes with a bevel gear 2 209. A transmission rod 210 is fixedly mounted at the center of the bevel gear 209. A bevel gear 3 211 is fixedly mounted on the end of the transmission rod 210 away from the bevel gear 209. This bevel gear 3 211 meshes with a bevel gear plate 212. The transmission rod 210 is rotatably mounted on the inner wall of the inner adjustment groove 3. A fireproof sealing plate 213 is fixedly mounted on the outer side of the bevel gear plate 212. The fireproof sealing plate 213 is vertically movable and disposed inside the mounting frame 5.

[0032] Vertical grooves 4 are vertically opened on the inner walls on both sides of the installation frame 5, and one side of the fireproof sealing plate 213 is movably set on the inner side of the vertical groove 4 through a fixed bevel tooth plate 212, and the other side of the fireproof sealing plate 213 is fixedly equipped with a slider, and the other side of the fireproof sealing plate 213 is movably set on the inner side of the vertical groove 4 through the slider.

[0033] According to the above embodiment, the working principle of the present invention is:

The controller is electrically connected to the smoke alarm, fire alarm, temperature sensor, buzzer, backup battery and is also connected to the servo motor 204.

[0035] When the fire alarm body 201 detects a fire, the buzzer sounds a fire warning alarm. At the same time, the servo motor 204 starts to rotate the reciprocating screw 203. The reciprocating screw 203 moves the screw block 202, so that the fire alarm body 201 moves from the outside to the inside of the embedded box 1. When the fire alarm body 201 moves, it moves along the inner adjustment groove 3 through the spur plate 205, and the spur gear 207 is engaged through the spur plate 205. The rotating spur gear 207 drives the shaft 206 to rotate, so that the shaft 206 drives the bevel gear 1 208. The bevel gear 1 208 is engaged with the bevel gear 209, and the bevel gear 209 drives the transmission rod 210 to rotate.

[0036] The rotating transmission rod 210 rotates the bevel gear three 211, and the bevel gear three 211 engages and transmits the bevel gear plate 212, so that the bevel gear plate 212 is driven by the bevel gear three 211 to move the fireproof sealing plate 213 on the inner side of the mounting frame 5 along the vertical groove 4 toward the embedded box 1, and the fire alarm body 201 is sealed and set inside the embedded box 1, which can reduce the damage to the fire alarm body 201 caused by the burning of the fire when a fire occurs.

[0037] In the present invention, unless otherwise clearly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly specified and limited, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0038] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention.
