[0006] A perfluorohexanone fire extinguishing device with an anti-misoperation function comprises a gas producing chamber, a fire extinguishing agent chamber connected to the gas producing chamber, and an atomizing nozzle connected to the fire extinguishing agent chamber, wherein a temperature-sensitive self-starting electric squib is installed on the atomizing nozzle, and the temperature-sensitive self-starting electric squib comprises a shell, a gas producing agent, a temperature-sensitive thermistor, an electric ignition head and a puncture needle, wherein a gas producing cavity is provided in the shell, the gas producing agent is encapsulated in the gas producing cavity, the electric ignition head is installed at one end of the gas producing cavity and contacts with the gas producing agent, the thermistor is connected to the electric ignition head, and the puncture needle is installed at the other end of the gas producing cavity, and the end of the puncture needle away from the gas producing cavity extends into the atomizing nozzle and corresponds to the diaphragm in the atomizing nozzle.

[0007] In order to realize wireless remote control of the perfluorohexanone fire extinguishing device, the perfluorohexanone fire extinguishing device further comprises a controller, and the controller is connected to the gas generating chamber.

[0008] In order to facilitate wireless remote control of the temperature-sensitive self-starting electric squib, the controller is connected to the electric ignition head.

[0009] In order to further improve the fire extinguishing ability of the perfluorohexanone fire extinguishing device, the perfluorohexanone fire extinguishing device is a double-spray type, and fire extinguishing agent chambers are respectively installed at both ends of its gas production chamber, and atomizing nozzles are respectively installed on the fire extinguishing agent chambers, and temperature-sensitive self-starting electric explosion tubes are respectively installed on the atomizing nozzles.

[0010] The beneficial effect of the utility model is that the perfluorohexanone fire extinguishing device with anti-misoperation function adds a temperature-sensitive self-starting electric squib on the original basis, and the temperature-sensitive self-starting electric squib is wirelessly remotely started by the controller. If the fire extinguishing device is started by mistake, as long as the electric squib is not started to open the internal diaphragm of the atomizing nozzle, the fire extinguishing agent will not be sprayed out, thereby achieving the anti-misoperation effect and ensuring the safety and reliability of the fire extinguishing device when in use.

[0013] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0014] like Figure 1 A perfluorohexanone fire extinguishing device with an anti-misoperation function is shown, comprising a gas producing chamber 1, a fire extinguishing agent chamber 2 connected to the gas producing chamber 1, and an atomizing nozzle 3 connected to the fire extinguishing agent chamber 2. The perfluorohexanone fire extinguishing device is a double-spray type, and the left and right ends of the gas producing chamber 1 are respectively equipped with fire extinguishing agent chambers, and the fire extinguishing agent chambers 2 are respectively equipped with atomizing nozzles 3, and the atomizing nozzles 3 are detachably connected to the fire extinguishing agent chamber 2. Temperature-sensitive self-starting electric detonators 4 are respectively installed on the two atomizing nozzles 3, and a controller 5 is installed on the gas producing chamber 1.

[0015] The controller signal of the controller 5 in this device can be directly sent to the mobile terminal, with a wireless remote one-key start function, and the device can also be automatically started. When an initial flame is found or the detector sends an initial fire signal, the operator can take corresponding measures according to the fire level, or directly start the device remotely with one key to extinguish the initial fire. The controller 5 in this device has both the function of detecting signals and automatically starting, and also has the function of sending and receiving remote data signals.

[0016] Specifically, combined Figure 2The temperature-sensitive self-starting electric detonator shown includes a shell 401, a gas generating agent 404, a temperature-sensitive thermistor 403, an electric ignition head 402 and a puncture needle 405.

[0017] When the detector detects the temperature, smoke, CO, and combustible gas alarm values ​​in the protected area, the detector signal transmits the alarm signal to the mobile terminal through the controller. The operator can take corresponding measures according to the alarm level displayed on the mobile terminal, or directly start the device remotely through the mobile terminal with one click. When the temperature exceeds the set value, the device can be judged as a fire, and the temperature-sensitive self-starting electric squib with self-starting function is started. The electric ignition head 402 ignites the gas generating agent 404 to push the piercing needle 405 to open the diaphragm 301 inside the atomizing nozzle 3. The controller 5 will start the gas generating agent in the gas generating chamber 1, and push the perfluorohexanone fire extinguishing agent in the fire extinguishing agent chamber 2 to spray out from the two-end atomizing nozzle 3, and make the mist perfluorohexanone fire extinguishing agent diffuse in the entire space, which is conducive to covering the combustibles and achieving the fire extinguishing effect.
