The lower part of the support plates 1309 is provided with a limiting groove 1310. The locking pin 1308 on the cover 4 is aligned with the guide groove 1302, and then the cover 4 is rotated. When the locking pin 1308 moves into the opening groove 1306, the support plates 1309 will abut against the wedge surface of the limiting pin 1307. At this time, the limiting pin 1307 will move downward, and the spring 1305 will be Compression, when the limit pin 1307 is aligned with the limit slot 1310, the spring 1305 will reset the limit pin 1307. At this time, the limit pin 1307 will be locked in the limit slot 1310. At the same time, the limit pin 1307 will push the locking pin 1308 to be engaged in the limit hole 1301, thereby completing the rapid installation between the cover shell 4 and the mounting base 12, reducing the use of fixing bolts, improving installation efficiency, and facilitating the maintenance and inspection of the detection alarm by the staff.

[0023] A mounting plate 8 is fixedly installed on the upper part of the housing 4, a heat induction detector 10 is fixedly installed on one side of the bottom of the mounting plate 8, a smoke sensor 9 is fixedly installed on the other side of the bottom of the mounting plate 8, a mounting frame 2 is fixedly installed on the middle of the top of the mounting seat 12, a connecting pipe 3 is fixedly installed in the middle of the mounting frame 2, a micro water pump 7 is installed on the outer periphery of the connecting pipe 3, the upper part of the connecting pipe 3 is connected to the external water source, and a plurality of evenly distributed mounting holes 1 are opened on the top of the mounting frame 2. A plurality of evenly distributed branch pipes 6 are fixedly installed at the lower part of the mounting frame 2, and the upper parts of the branch pipes 6 are fixedly installed at the lower part of the connecting pipe 3. The smoke sensor 9 detects the smoke particles in the air to detect the fire. When the smoke particles in the air exceed a certain concentration, the detector will sound an alarm. The thermal induction detector 10 detects the fire by detecting the change of the ambient temperature. When the ambient temperature rises to a certain level, the detector will sound an alarm. At this time, the micro water pump 7 can pump external water along the connecting pipe 3 into the branch pipe 6, so as to extinguish the fire near the detector and prevent the fire from damaging the detector. In addition, the cover 4 and the mounting base 12 can be made of fireproof material to increase the fire resistance of the detector.

[0024] A plurality of evenly distributed notches 5 are provided on the outer periphery of the cover shell 4, a wedge-shaped surface is provided on the lower part of the limit pin 1307, the guide groove 1302 and the limit seat 1303 are both arc-shaped, a control chip 11 is fixedly installed in the middle of the bottom end of the mounting plate 8, and the control chip 11 is electrically connected to the smoke sensor 9, the thermal induction detector 10 and the micro water pump 7 respectively. Since the guide groove 1302 and the limit seat 1303 are both arc-shaped, the rotation of the cover shell 4 can be facilitated to avoid the pin 1308 being unable to rotate normally in the guide groove 1302 during rotation.

[0025] In actual use, the staff aligns the locking pin 1308 with the guide groove 1302. At this time, the cover shell 4 is rotated 90° counterclockwise, and the locking pin 1308 moves in the guide groove 1302. When the support plate 1309 moves into the opening groove 1306, the support plate 1309 will abut against the limit pin 1307, and then the limit pin 1307 will move, and the spring 1305 will be compressed. When the limit groove 1310 on the support plate 1309 is aligned with the limit pin 1307, the spring 1305 will push the limit pin 1307 into the limit groove 1310 to complete the limiting of the support plate 1309. At the same time, the limit pin 1307 will push the support plate 1309 drives the latch 1308 to enter the limiting hole 1301, completing the quick installation between the cover shell 4 and the mounting base 12. When disassembly is required, the staff pushes the cover shell 4 upward to make the latch 1308 disengage from the limiting hole 1301, and then rotates the cover shell 4 90° clockwise. At this time, the limiting pin 1307 will disengage from the limiting groove 1310. When the card plate disengages from the opening groove 1306, the cover shell 4 can be separated from the mounting base 12, which is convenient for the staff to inspect and maintain the relevant components inside the detector and improve the inspection efficiency. At the same time, the micro water pump 7 pumps water along the connecting pipe 3 to the branch pipe 6, which can extinguish the fire near the detector.
