The drum of contracting air.To in the middle of the 19th century, Charles Robert Richet Jia Liai has invented portable chemical fire extinguisher.By sodium bicarbonate and water
Mixing is placed in cylinder, another to contain sulfuric acid in bung hole with a vial.In use, being broken up in bottle by striker, make chemicals
Matter mixing, generates carbon dioxide, hydraulic pressure is gone out outside bucket.1905, the Laurent of Russia, which teaches, invented a kind of bubble in St. Petersburg
Aluminum sulfate and sodium bicarbonate solution are mixed and added into stabilizer, the foam containing carbon dioxide are generated after ejection by foam extinguishing agent,
Float on the oil, paint or gasoline of burning, can effectively starvation, stop up flame-out flame.1909, the Dai Weisen in New York obtained one
Patent extrudes carbon tetrachloride using carbon dioxide out of fire extinguisher, this liquid can be immediately turned into non-flammable heavier gas with
Suffocate flame.
Currently, there are many type of fire extinguisher, it can be divided by its move mode: portable and cart type；By driving extinguishing chemical
Power resources can be divided into: gas storage vial-type, pressure storage type, chemical equation；It can then be divided into again by the extinguishing chemical filled: foam,
Dry powder, alkyl halide, carbon dioxide, clear water etc..Hereafter there is dry powder extinguisher again, liquid carbon dioxide fire-fighting device etc. is a variety of small
Pattern fire extinguisher.
With being gradually increased for people's awareness of safety, people increasingly pay attention to safety fire fighting knowledge, and many schools also can
It often holds fire disaster escaping simulated maneuver and explains some knowledge on fire fighting, such as how to use fire extinguisher and other fire-fighting equipments.
But existing fire extinguisher is applied to teaching and increases the teaching difficulty of teacher, and whether teacher can not also to understand student real
The application method for understanding fire extinguisher causes the serious waste of resource if testing using real fire extinguisher.
Utility model content
The utility model proposes a kind of student instruction examination fire extinguishers, solve fire extinguisher in the prior art
The teaching difficulty of teacher is increased applied to teaching, and teacher can not understand the user whether student really understands fire extinguisher
Method, if the problem of being tested using real fire extinguisher, causing resource serious waste.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
The utility model a kind of student instruction examination fire extinguisher, including handle, nozzle and fire extinguisher bottle, it is described

Embedded with power switch start button, the fire extinguisher bottle is internally provided with pressure sensor and PLC controller, the fire extinguishing
USB interface is additionally provided on the side wall of device bottle body, the bottom of the fire extinguisher bottle is provided with inflating port, the fire extinguisher bottle
Inner bottom be further fixedly arranged on lithium polymer battery group.
As a kind of optimal technical scheme of the utility model, the pressure sensor and PLC controller are each attached to and go out
On the inner sidewall of firearm bottle body.
As a kind of optimal technical scheme of the utility model, the PLC controller and pressure sensor and voice are played
Device is electrically connected.
As a kind of optimal technical scheme of the utility model, protective cover is provided on the outside of the display screen.
As a kind of optimal technical scheme of the utility model, bottle stopper is provided at the inflating port.
As a kind of optimal technical scheme of the utility model, the lower end side of the fire extinguisher bottle is provided with charging
Mouthful.
The utility model beneficial effect achieved is: the utility model is applied to be provided with display on the fire extinguisher of teaching
Screen, teacher can be by the use steps of fire extinguisher by display screen loop play, and student can be according to the behaviour of display screen when learning
Make carry out learning manipulation, the workload of teacher can not only be greatly reduced, but also can increase the interest of student, Neng Gouti
The learning efficiency of high student；When examination test, display screen is turned off, air is poured in fire extinguisher increases its pressure, if learning
It generates function and opens fire extinguisher, pressure is reduced, and speech player reminds test passes, allows the teacher to the grasp feelings for understanding student
Condition, and economize on resources, it is suitable for school instruction and examination uses.
