[0034] Optionally, an outer box 5 is further included, the outer box 5 is arranged on the chassis 1, a power box 51 is arranged on the outer box 5, a power source is arranged in the power box 51, and the power source is connected to the initiator 31 through a thermal line. By setting the power box 51, when receiving a start signal from the fire extinguishing controller, the initiator 31 is started by controlling the thermal line, and the heat generated by the start starts the generator 32, so that a large amount of fire extinguishing gas is generated by the reaction to achieve fire extinguishing.

[0035] Furthermore, a movable cover 52 is provided on the side of the outer box 5, and a handle 53 is provided on the side of the outer box 5.

[0037] In a preferred embodiment of the utility model, a cover plate 42 is provided on the inner box frame 4, and a one-way sealing valve 6 is provided on the cover plate 42. Specifically, the one-way sealing valve 6 includes a valve body 61 and a valve flap 62; the valve body 61 is provided on the cover plate 42, a fluid channel 611 is provided in the valve body 61, one end of the fluid channel 611 is an input end 6111, the other end of the fluid channel 611 is an output end 6112, and an outlet 612 is formed at the end of the valve body 61; the valve flap 62 is rotatably provided in the valve body 61, and the valve flap 62 has an open state and a closed state; in the open state, the valve flap 62 does not contact the output end 6112, so that the input end 6111 is connected to the outlet 612 through the output end 6112; in the closed state, the valve flap 62 abuts against the output end 6112, so that the input end 6111 is not connected to the outlet 612.

[0038] When a fire is detected, the hot melt glue fire extinguishing device sprays out fire extinguishing gas, which flows from the input end 6111 of the valve body 61 to the fluid channel 611, and then drives the valve flap 62 to rotate, so that the valve flap 62 switches from a closed state to an open state, so that the fire extinguishing gas is output from the outlet 612 at the end of the valve body 61 to extinguish the fire source.

[0039] like Figure 8 As shown, a plurality of fire extinguishing groups are arranged side by side, and the outlet 612 of the valve body 61 of each fire extinguishing group is connected together through the collecting pipe 10, and each fire extinguishing group corresponds to a protection zone.

By providing the elastic pad 623, in the closed state, the elastic pad 623 abuts against the output end 6112, and under the action of the deadweight of the valve flap 62 or the airflow, the elastic pad 623 is tightly deformed and tightly pressed against the output end 6112, and the sealing effect is better. When installing the elastic pad 623 , the connecting piece 626 is passed through the gasket 625 and the connecting port 6231 in sequence and then connected to the connecting groove, so that the elastic pad 623 is firmly locked on the petal body 622 .
