Preferably, the material of described internal layer is flame retardancy plastic plate；The material of described outer layer is cellular aluminium sheet.
Preferably, the material of described thawing plate is paraffin, and described extinguishing chemical is potassium salt dry powder or sodium bicarbonate dry powder.
Preferably, in described controller, audible-visual annunciator is set.
Preferably, described lead-in wire is connected with explosive also by switch, and described switch is mechanical type manual switch or electromagnetic switch.
This utility model has the advantages that the chemicals very first time of burning in experiment cabinet can be put out a fire by Automatic Fire Extinguisher, extinguishing chemical can be disperseed by rotating vane to surrounding, the fire extinguishing scope making Automatic Fire Extinguisher can cover the corner location in experiment cabinet, good extinguishing effect.The igniting of lighter judges it is to be judged by the temperature in experiment cabinet, the accuracy of judgement to fire.

Detailed description of the invention
nullA kind of temperature-sensitive automatic fire extinguisher as shown in Figure 1-Figure 3，Including the controller 1 being arranged in laboratory，Controller 1 and the sender unit 21 of setting on the Automatic Fire Extinguisher 2 being arranged in the experiment cabinet in laboratory、The temperature sensor 22 being arranged in laboratory、By the way of wired or wireless, signal is transmitted between photographic head 23，Described Automatic Fire Extinguisher 2 includes being arranged on the fixing axle 3 of middle position in experiment cabinet，On fixing axle 3, holding vessel 4 is installed、The lower end of holding vessel 4 arranges extinguishing chemical outlet 5，Described holding vessel 4 is double-deck hollow cylinder，Extinguishing chemical is placed in the inner side of its internal layer 6，On the sidewall of described internal layer 6, multiple passage is set，Set-point firearm 8 between outer layer 7 and the internal layer 6 of described holding vessel 4，Described lighter 8 includes going between 9、Ignition coil 10、Explosive 11，One end of described lead-in wire 9 is connected with the side of chip type spring 12，The other end is connected with power supply，The opposite side of described chip type spring 12 is connected with the side melting plate 13，The opposite side of described thawing plate 13 is connected with one end of ignition coil 10，The other end of described ignition coil 10 is connected with explosive 11；The lower end of described extinguishing chemical outlet 5 arranges the rotating vane 14 that can rotate relative to fixing axle 3.In order to improve safety further, in described controller 1, also set up audible-visual annunciator 24.
In order to increase the safety of Automatic Fire Extinguisher 2, the material of described internal layer 6 is flame retardancy plastic plate；In order to allow the abundant induced environment temperature of lighter 8, the material of described outer layer 7 is cellular aluminium sheet.
The using method of described temperature-sensitive automatic fire extinguisher is: when normally using, and the ambient temperature that chemical experiment is indoor is monitored in temperature sensor 22, it is ensured that temperature meets the memory requirement of experiment product, and sender unit 21 sends normal signal to controller 1.When the chemicals in certain experiment cabinet starts to burn because of leakage in cabinet, then the temperature in experiment cabinet rises, thawing plate 13 in lighter 8 melts as liquid, chip type spring 12 deforms, the side making chip type spring 12 contacts with ignition coil 10, owing to the opposite side of chip type spring 12 is connected with charged lead-in wire 9, therefore ignition coil 10 is charged, and the explosive 11 that ignites, described explosive 11 is the granular solids that Hydrazoic acid,sodium salt is mixed to form with ammonium nitrate, it produces a large amount of nitrogen after igniting, nitrogen enters the inner side of internal layer 6 by the passage on internal layer 6 sidewall, and mix with extinguishing chemical, from extinguishing chemical outlet 5 ejection.Described extinguishing chemical outlet 5 can arrange papery baffle plate, papery baffle plate carrying extinguishing chemical under normal circumstances, papery baffle plate is broken through with extinguishing chemical after a large amount of nitrogen mix, the material of described thawing plate 13 is configured according to the burning-point of article in experiment cabinet, for some chemicals, melt plate 13 and can select paraffin.Described extinguishing chemical is also required to select accordingly according to the article in experiment cabinet, and for some chemicals, extinguishing chemical can be potassium salt dry powder or sodium bicarbonate dry powder.
The mixture of extinguishing chemical and nitrogen is after extinguishing chemical outlet 5 ejection, and impact rotating vane 14 makes it rotate, then extinguishing chemical and nitrogen can be disperseed by rotating vane 14 uniformly to surrounding, make the corner location in experiment cabinet sufficiently to put out a fire.
While Automatic Fire Extinguisher 2 fire extinguishing, sender unit 21 stops sending normal signal.Then controller 1 judges fire occur, and controls audible-visual annunciator 1 and send sound and light alarm signal, and the staff near prompting, photographic head 23 is started working simultaneously, and the scene condition of a fire passes to security protection personnel, and the intensity of a fire in laboratory is judged by help.
Preferably embodiment is, described lead-in wire 9 is connected with explosive 11 also by switch 15, and described switch 15 is mechanical type manual switch or electromagnetic switch.So when an experiment cabinet catches fire, fire fighter can be by Automatic Fire Extinguisher 2 manual unlocking in neighbouring experiment cabinet, or control relevant electromagnetic switch by controller 1 to be opened by Automatic Fire Extinguisher 2, in advance the experiment cabinet near fire area is carried out preventive fire prevention process.
