Description
Technical field
The present invention relates to technical field of fire control, more particularly to safe hand-held fire extinguisher.
Background technology
Existing hand-held fire extinguisher is using relatively broad, although its structure is smaller, there are larger security risk.
For example when detonation or spray nozzle clogging occur for the powder column in cylinder, extinguishing chemical will rapidly gather in cylinder, the pressure in cylinder
Power can hurried rise, then thermal energy be converted into huge kinetic energy, act on cylinder, a part protecgulum is rushed along spout direction
Before being opened to, while another part acts against the recoil that opposite direction is produced on cylinder, it is acted on will with operating personnel
Bring serious personal injury, the protecgulum in addition rushed out due to its impulse force it is larger also can after cylinder is departed to surrounding people or
Thing causes unexpected injury.
Occur on the market at present with the hand-held fire extinguisher for unloading quick-fried device, it is existing when occurring above-mentioned unexpected
Unloading quick-fried device can be rapidly by ejection of the dry powder fire extinguishing agent in fire extinguisher without guiding, to reduce cylinder pressure, but without guiding
Injection be easy to accidentally injure operating personnel, meanwhile, the injection for no guiding will make dry powder fire extinguishing agent can not act on ignition point,
And then cause the waste of extinguishing chemical, situation severe patient, it is also possible to miss optimal fire extinguishing opportunity cause loss increase.
The content of the invention
To solve in the prior art, security risk, the technical problem of the wasting of resources, skill of the invention existing for explosion venting device

Safe hand-held fire extinguisher in the present invention, compared with prior art, its advantage is：
Safe hand-held fire extinguisher in the present invention, when in use, protecgulum is blocked when there is the dry powder fire extinguishing agent in cylinder
Spout, when causing the dry powder fire extinguishing agent to can not be successfully ejection, immense pressure will be persistently produced in cylinder, when pressure exceedes threshold value,
Protecgulum is released cylinder and pulls the outer wall slip for unloading quick-fried ring in cylinder, the first limiting device and the second spacing dress by dry powder fire extinguishing agent
Quick-fried ring can will be unloaded and be fastened in the end of cylinder by putting, and avoided protecgulum from launching away and accidentally injured other people, meanwhile, the pressure in cylinder is released
Put, dry powder fire extinguishing agent successively through unloading quick-fried through hole, dry powder guiding cover and guide port spray to protecgulum direction, avoid through unloading it is quick-fried or
The random injection of dry powder fire extinguishing agent after release or vertical injection, and through unloading it is quick-fried after fire extinguisher can also be led to
Fire-extinguishing operations are realized in the direction that catches fire, and above-mentioned design not only increases the security that fire extinguisher unloads quick-fried device, also help saving money
Source, makes dry powder fire extinguishing agent be fully used.
