[0031] A third ventilation pipe 203 is provided on the right side of the bottom of the valve body 2, and a pressure sensor 209 is installed on the right end of the third ventilation pipe 203. The right end of the pressure sensor 209 is connected to a connecting wire 2012. The connecting wire 2012 and the ignition wire 302 are both electrically connected to the controller in the fire control room.

[0032] A powder splashing plate 207 is provided at the bottom of the U-shaped frame 204 , and an L-shaped mounting plate 208 is fixedly connected to the lower front portion of the U-shaped frame 204 , and an angle adjustment component 4 is provided on the front side of the L-shaped mounting plate 208 .

[0033] A fixing plate 2010 is fixedly connected to the right side of the L-shaped mounting plate 208 , and an audible and visual warning device 2011 is installed on the right end surface of the fixing plate 2010 .

[0035] The working principle of this embodiment is as follows: during use, when a fire occurs near the main body 1 of the suspended fire extinguisher, the flame temperature rises, and the temperature-sensitive glass ball 206 senses the temperature in real time. When the temperature sensed by the temperature-sensitive glass ball 206 exceeds the operating temperature of the temperature-sensitive glass ball 206, the temperature-sensitive glass ball 206 explodes due to the heat, causing the sealing gasket provided on the nozzle at the bottom of the valve main body 2 to lose its fixing function, and then the sealing gasket falls under the action of the internal air pressure of the main body 1 of the suspended fire extinguisher, and then the fire extinguishing agent inside the main body 1 of the suspended fire extinguisher is quickly sprayed out, and the fire is extinguished by the released fire extinguishing agent.

[0036] In the early stage of a fire, after receiving a signal that a fire has occurred in a building, the staff in the fire control room can actively supply power to the ignition wire 302 through the controller in the fire control room, and transmit the electricity to the electronic ignition device 304 through the ignition wire 302. Then the electronic ignition device 304 starts to operate and ignites the black powder 305. After the black powder 305 is ignited, a violent chemical reaction will occur, generating a large amount of nitrogen, carbon dioxide and other gases. The volume of these gases expands rapidly and the pressure increases violently, so that the impact head 303 can be quickly pushed out to the right, causing the impact head 303 to be quickly launched to the right, and then the temperature-sensitive glass ball 206 can be broken, so that the fire extinguishing agent inside the suspended fire extinguisher body 1 can be quickly sprayed out.

[0037] The internal pressure of the valve body 2 is detected in real time by the pressure sensor 209. Thus, when the internal pressure of the hanging fire extinguisher body 1 is low, the pressure sensor 209 transmits the low pressure signal to the controller in the fire control room via the connecting wire 2012. The controller in the fire control room then activates the sound and light alarm 2011 to emit a warning sound and a warning light, thereby providing an effective warning to maintenance personnel. There is no need to actively observe the pressure gauge 205 to detect the low internal air pressure of the hanging fire extinguisher body 1, thereby avoiding the phenomenon that the internal fire extinguishing agent of the hanging fire extinguisher body 1 cannot be effectively sprayed out when a fire occurs.
