[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown:

[0041] The main body 5 is the basic structural member of the present invention.

[0042] The fire extinguisher 24 is placed on the base 51 of the main body 5 and is fixed on the main body 5 by two sets of locking hoops 3 from top to bottom.

[0043] The side cover 1 and the side cover 2 are respectively fixedly connected to the main body 5, and the locking hoop 3 and the fire extinguisher 24 are contained therein.

[0044] There is a groove 52 on the rear surface of the main body 5, and the handle 141 formed by the connection of the handle upper cover 14 and the handle lower cover 11 is accommodated in the groove 52, and the handle hinge shaft 13 passes through the middle part of the handle lower cover 11 (that is, the middle part of the handle 141) and the main body 5 to hinge the handle 141 to the main body 5.

[0045] A spring sheet 12 with a curved protrusion 122 in the middle is located in front of the handle 141 , and shafts 121 on both sides of the spring sheet 12 are inserted into shaft holes 120 on both sides of the groove 52 .

[0046] Two side panels 53 are provided downward from the top of the main body 5, and each side panel 53 is provided with a guide groove. The key shaft 7 passes through the key 8, and the two ends of the key shaft 7 are inserted into the guide groove. In this way, the key 8 is hung between the two side panels 53 by the key shaft 7, and the guide groove plays a guiding role. The key 8 can move forward and backward and is guided by the cooperation of the key shaft 7 and the guide groove.

[0047] Two protrusions 54 are respectively provided on the outer sides of the two side plates 53 (one protrusion 54 of one side plate 53 is shown in the figure), and the two protrusions 54 are located in front of the key shaft 7. Each side plate 53 is equipped with an elastic cord 10, and the middle of the loops 101 at both ends of the elastic cord 10 is a middle part 102, the two loops 101 are hung on the two protrusions 54, and the middle part 102 is hung on the key shaft 7. In this way, due to the elastic force of the elastic cord 10, the movable key shaft 7 is tightened, and when there is no external force or the external force is slight, the key shaft 7 has a tendency to reset, so that the key shaft 7, the key 8, and the structure of the pressure plate 9 described below will not shake.

[0048] A cavity 81 is provided on the lower surface of the key 8 . In fact, the key 8 is a shell structure having a cavity 81 open at the bottom.

[0049] A pressing plate 9 is hinged to the main body 5 via a pressing plate hinge shaft 6 .

[0050] The pressing plate 9 is located between the two side plates 53 and below the button 8 .

[0051] The middle of the pressing plate 9 has a through slot 91 , and the front end of the pressing plate 9 has an upward protrusion 92 .

[0052] When the handle 141 is accommodated in the groove 52 , the upper end 111 of the handle lower cover 11 (that is, the upper end of the handle 141 ) passes through the through slot 91 of the pressing plate 9 , extends into the cavity 81 of the button 8 , and presses against the rear wall of the cavity 81 .

[0053] At this time, the button 8 is located at the rear limit position, and the lower surface of the front end of the button 8 presses the protrusion 92 of the front end of the pressing plate 9. The protrusion 92 is to make the button 8 better press and drive the pressing plate 9 after rotation.

[0054] The lower surface of the pressing plate 9 presses the button 241 at the top of the fire extinguisher 24 . An air nozzle member 4 is fixed on the main body member 5 . The nozzle of the fire extinguisher 24 faces the nozzle of the air nozzle member 4 .

[0055] At this time, the button 8 is limited and stopped by the upper end 111 of the handle lower cover 11 and cannot be pushed forward, that is, the pressing plate 9 cannot press down the button 241 at the top of the fire extinguisher 24, and the fire extinguisher 24 will not be accidentally opened, which is highly safe.

[0056] A magnet 17 is fixedly disposed at the lower portion of the handle 141 .

[0057] An iron sheet 16 and a Hall displacement sensor 15 are fixedly mounted on the main body 5 corresponding to the magnet 17 .

[0058] The magnet 17 and the iron sheet 16 attract each other, preventing the handle 141 from accidentally rotating and opening the fire extinguisher 24.

[0059] A reset button PCB board 18 is provided on the rear surface of the lower part of the main body 5 , and the reset button 19 is installed at a position corresponding to the reset button PCB board 18 .

[0060] A lower cover 23 is fixedly provided at the lower end of the main body 5, and a light transparent part 23 made of transparent material is fixedly provided inside the lower cover 23. A light PCB board 21 equipped with an LED light and a sound alarm is fixedly provided above the light transparent part 23. A battery 20 for powering the light PCB board 21, the Hall displacement sensor 15, and the reset button PCB board 18 is also fixedly provided inside the lower cover 23.

[0061] The light PCB board 21 is respectively connected to the Hall displacement sensor 15 and the reset button PCB board 18 circuits.

[0062] The lighting PCB board 21 also has a Bluetooth BLE or NB low power communication module 100 .

[0063] The above constitutes one fire extinguisher unit 100 .

[0064] like Figure 4 , Figure 5 , Figure 6 As shown:

[0065] There are multiple fire extinguisher units 100 in a network of a smart fire extinguisher system, and the Bluetooth BLE or NB low-power communication module 101 of the fire extinguisher unit 100 is connected to the central processor 200 through the relay local area network and the public Internet. The central processor 200 is connected to the mobile phone 300 installed with the smart fire extinguisher system APP through the relay local area network and the public Internet.

[0066] When a fire occurs around a fire extinguisher unit 100:

[0067] The user holds the main body 5 of the fire extinguisher unit 100, overcomes the attraction between the magnet 17 and the iron sheet 16 and lifts up the handle 141. At this time, the handle 141 rotates around the handle hinge shaft 13, and the upper end 111 of the handle lower cover 11 rotates downward to leave the cavity 81 of the button 8. Since the upper end 111 of the handle lower cover 11 (that is, the upper end of the handle 141) passes through the through slot 91 of the pressing plate 9, the upper end 111 of the handle lower cover 11 will not interfere with the pressing plate 9.

[0068] After the handle 131 is rotated, the upper end 111 of the handle lower cover 11 presses the curved protrusion 122 in the middle of the spring sheet 12 to deform it, and the restoring force of the spring sheet 12 helps to restore the handle 141 after use.

[0069] In this way, the user can push the button 8 further forward, the button 8 slides forward to the front limit, pressing down the protrusion 92 at the front end of the pressure plate 9, and the pressure plate 9 rotates downward around the pressure plate hinge shaft 6, thereby pressing down the button 241 at the top of the fire extinguisher 24, and the fire extinguishing agent of the fire extinguisher 24 is sprayed out from the nozzle of the fire extinguisher 24, and further sprayed out from the nozzle of the air nozzle piece 4 to extinguish the fire.

[0070] The lower part of the handle 141 leaves the groove 52. At this time, the magnet 17 is away from the Hall displacement sensor 15. The Hall displacement sensor 15 sends the signal of the displacement of the magnet 17 (that is, the signal of the displacement of the handle 141, which means that the fire extinguisher 24 is turned on and there is a fire) to the lighting PCB board 21. The lighting PCB board 21 starts the LED light to flash and the sound alarm to sound.

[0071] At the same time, the signal will be sent to the central processor 200 through the Bluetooth BLE or NB low-power communication module 101, through the relay local area network and the public Internet. The central processor 200 sends a control signal to the Bluetooth BLE or NB low-power communication module 101 of other fire extinguisher units 100 in the network. The Bluetooth BLE or NB low-power communication module 101 receives the control signal to control the light PCB board 21 of the fire extinguisher unit 100, and the light PCB board 21 starts the LED light flashing and the sound alarm sounds.

[0072] At the same time, the signal and the position signal of the fire extinguisher unit 100 (that is, the position signal of the first activated fire extinguisher unit 100) are sent to the central processor 200 via the public Internet, and the central processor 200 sends the control signal to the smart fire extinguisher APP provided in the mobile phone 300.

[0073] Application scenarios:

[0074] When the user finds that the LED light of a nearby fire extinguisher unit 100 suddenly flashes and the sound alarm sounds, he knows that a certain fire extinguisher unit 100 in the system has been activated to extinguish the fire. At this time, the user opens the smart fire extinguisher APP of the mobile phone 300. The smart fire extinguisher APP of the mobile phone 300 will display the location of the first activated fire extinguisher unit 100 and the escape route from the fire extinguisher unit 100 near the user.

[0075] In this way, the user can choose to pick up the nearest fire extinguisher unit 100 and go to the location of the first activated fire extinguisher unit 100 to help extinguish the fire, or choose to pick up the nearest fire extinguisher unit 100 and escape according to the escape route. The fire extinguisher unit 100 is used to extinguish the fire obstacles in front during the escape process.

[0076] The manager of the central processor 200 can timely find the location where the first fire extinguisher unit 100 is used, and make an alarm and unified dispatch.

[0077] When the reset button 19 of the fire extinguisher unit 100 is pressed, the reset button PCB board 18 sends a signal to the light PCB board 21, and the LED light and the sound alarm stop working.
