There is a master switch 200 at the driver's location that is connected to a local area network signal transmission module 300.

In actual use:

under normal conditions:

a battery electric quantity signal of the battery electric quantity detector, a fire extinguisher bottle air pressure signal of the fire extinguisher bottle air pressure detector and a time signal of a fire extinguisher bottle validity timer (which is adjusted to count down in advance) are sent to a signal receiving circuit of the PCB control board 5, then the signal receiving circuit sends the signals together with the ID identity signal of the fire extinguisher to a central control computer of a vehicle management center through a 5G network WIFI module and a 5G public internet, the software of the central control computer performs statistics, if the battery power is low excessively, the bottle atmospheric pressure of putting out a fire is low excessively, and the bottle of putting out a fire is close to the deadline, then the alarm module of software sends alarm signal, and the administrator can fix a position the fire extinguisher according to alarm data and the ID identification signal of fire extinguisher, sends the people to change the battery, changes daily management actions such as bottle of putting out a fire, need not manual inspection like this, greatly reduced and management maintenance cost.

Under the condition of fire:

when a passenger presses a button 44 of any fire extinguisher, the button 44 rises to abut against the lower surface of a torsion block 46, the torsion block 46 rotates around a hinge shaft 47 to tilt, the steel wire rope 40 is pulled to be away from the mechanical rocker 9, the steel wire rope 40 fixed at the tail part of the mechanical rocker 9 pulls the tail part of the mechanical rocker 9 to descend, and then the mechanical rocker 9 rotates around a shaft fixing rivet 7 relative to the fixing piece 8. The rotating mechanical rocker 9 presses the trigger switch 181 at the top end of the gas spring 18, the piston 182 at the bottom end of the gas spring 18 descends, the fire extinguishing bottle 2 below is opened, and the environment-friendly fire extinguishing agent of the fire extinguishing bottle 2 is sprayed into the vehicle from the fire extinguishing pipe 23 to extinguish the fire.

At this time, the mechanical rocker 9 presses the travel switch 12, the travel switch 12 sends a signal to the signal receiving circuit of the PCB control board 5, the signal receiving circuit sends a signal to the lan signal transmitting and receiving module of the other vehicle-mounted fire extinguisher of the same vehicle at a short distance through the lan signal transmitting and receiving module, the signal is sent from the lan signal transmitting and receiving module to the signal receiving circuit of the PCB control board 5, the signal receiving circuit sends a signal to the motor control circuit, the motor control circuit starts the motor 16, the output shaft of the motor 16 drives the motor telescopic screw 15 to rotate, since the nut 11 is fixed on the tail of the electric rocker 10 in a non-rotatable manner and the motor telescopic screw 15 is screwed with the nut 11, the nut 11 descends and drives the tail of the electric rocker 10 to descend, the electric rocker 10 presses the bump 91 to press the mechanical rocker 9, the mechanical rocker 9 presses the trigger switch 181 at the top end of the air spring 18, the piston 182 at the bottom end of the gas spring 18 descends to open the fire bottle 2 below, and the environment-friendly fire extinguishing agent of the fire bottle 2 is sprayed into the vehicle from the fire extinguishing pipe 23 to extinguish the fire.

Like this, start a fire extinguisher, all in-car fire extinguishers are all started and are put out a fire simultaneously, have promoted extinguishing efficiency greatly.

When the travel switch 12 is switched on, a signal is sent to a signal receiving circuit of the PCB control board 5, the signal receiving circuit sends a signal to a motor control circuit, the motor control circuit judges whether a signal for starting the motor 16 exists or not, the first fire extinguisher which is started by pressing the button 44 with a hand through the steel wire rope 40 and pulling the mechanical rocker 9, the motor 16 is not started, but the motor control circuits of other fire extinguishers all send a signal for starting the motor 16, the motor 16 is started, therefore, if the signal for starting the motor 16 is judged to be sent, the motor control circuit outputs a control signal to the motor 16 after delaying, the motor 16 is controlled to rotate reversely, the output shaft of the motor 16 drives the motor telescopic screw 15 to rotate reversely, the nut 11 rises, the tail part of the electric rocker 10 rises and returns to the initial position, thus facilitating the resetting of the gas spring 18 and replacing the fire extinguishing bottle 2, and is ready for the next job. If the motor 16 does not rotate reversely to reset the electric rocker 10, the electric rocker 10 is clamped by the nut 11, the manual reset is difficult, the mechanical rocker 9 always presses the trigger switch 181 at the top end of the gas spring 18, the piston 182 of the gas spring 18 cannot reset, and the fire extinguisher 2 cannot be replaced.

After releasing the button 44, the reset tension spring 45 resets the button 44, the torsion spring 42 resets the torsion block 46, so that the steel wire rope 40 resets, the mechanical rocker 9 resets, the piston 182 of the air spring 18 resets manually, and after all mechanisms reset, the used fire extinguishing bottle 2 is replaced, so that the fire extinguishing bottle can be used next time.

Alternatively, the driver may press the main switch 200 to send a signal to the lan signal transmitter/receiver module of all the fire extinguishers of the same vehicle through the lan signal transmitter module 300, and all the fire extinguishers are driven by the motor 16 to extinguish the fire by the above operation.

Meanwhile, the travel switch 12 sends signals to a signal receiving circuit of the PCB control panel 5, the signal receiving circuit sends the signals together with ID identity signals of the fire extinguishers to a central control computer of a vehicle management center through a 5G network WIFI module and a 5G public internet, software of the central control computer gives an alarm, a manager can know which vehicle fire extinguishers are started immediately, measures such as fire fighting before taking nearby fire fighting and the like are taken, and the fire extinguishing efficiency is greatly improved.
