Description
Technical field
The utility model relates to fire-fighting equipment field, in particular to a kind of fire extinguisher.
Background technique
Fire extinguisher is a kind of portable Fire extinguisher.Chemical substance is placed in fire extinguisher, to rescue fire extinguishing calamity.Fire extinguisher is
One of common fireproofing installation is stored in public place or the place of fire may occur, filling in different types of fire extinguisher
Ingredient it is different, be the equipment for aiming at different fire alarms and setting.Fire extinguisher includes dry powder extinguisher and carbon-dioxide fire engine
Device, the fire-fighting principle of dry powder extinguisher are as follows: the powder that dry powder extinguisher ejects is fallen in outside combustible surface, and it is anti-that chemistry occurs
It answers, and forms one layer of glassy coating under high temperature action, thus isolating oxygen, and then fire smothering.And carbon-dioxide fire engine
The fire-fighting principle of device are as follows: the liquid carbon dioxide that carbon dioxide extinguisher ejects gasifies rapidly, rapidly reduces at combustion fire
Oxygen content generates smothering action and puts out a fire.
Currently, the Chinese utility model patent that notification number is CN206979875U discloses a kind of dry powder convenient to use and goes out
Firearm, including horn mouth, three-level jet pipe, second level jet pipe, level-one jet pipe, pressure gauge, hand-held fixed frame, fire extinguisher release pressure handle,

The Position Design on fire extinguisher head holds fixed frame in above-mentioned technical proposal, enables a user to both hands control and goes out
Firearm avoids the problem that the lesser people of strength is not available fire extinguisher, but has the following deficiencies: that the fire-fighting principle of the fire extinguisher is
Ordinary dry chemical fire extinguisher principle, fire extinguishing means are single, can not quickly reduce the oxygen content at burning, extinguishing effect is general.
Utility model content
In view of the deficienciess of the prior art, the fire extinguisher can the purpose of the utility model is to provide a kind of fire extinguisher
Combustible surface forms one layer of glassy coating, and can reduce rapidly the oxygen content at burning, so that comburant is completely and oxygen
Air bound is exhausted, good extinguishing effect.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of fire extinguisher connects including the internal tank body full of high pressure gas, the injection valve being fixed on tank body, with injection valve
Logical nozzle and the oviduct being connected to nozzle；Be equipped in the tank body first partition fixed with the inner tank wall, with
The inner tank wall fix and be located at second partition and one end on the downside of the first partition be connected to the injection valve it is another
End sequentially passes through the delivery pipe of the first partition Yu the second partition；Liquid titanium dioxide is equipped on the downside of the second partition
Carbon, the second partition upside are equipped with dry powder；The flour opening on the upside of the second partition is offered in the delivery pipe.
By using above-mentioned technical proposal, when injection valve is open, the high pressure gas in tank body on the upside of second partition sprays,
So that the dry powder being set on the upside of second partition is mixed in high pressure gas and is entered in delivery pipe by flour opening, finally through overspray
Valve, nozzle and oviduct are ejected at burning, so that the comburant surface at burning forms coating, so that comburant
With oxygen-barrier, to achieve the purpose that fire extinguishing；Simultaneously, the high pressure gas when injection valve is open, on the downside of second partition
Compressing liquid carbon dioxide enters to be sprayed from oviduct together in delivery pipe and finally with dry powder, so that the oxygen content at burning is fast
Speed reduces, so that comburant lacks the oxygen to burn, to extinguish the flame on comburant；The fire extinguisher is set
It sets, one layer of glassy coating can be formed in combustible surface and reduces rapidly the oxygen content at burning, so that comburant
Completely and oxygen-barrier, so extinguishing effect is obvious.
The utility model is further arranged to, and the dry powder is set on the downside of the first partition, and the flour opening is located at
On the upside of the first partition；Intercommunicating pore is offered in the first partition.
By using above-mentioned technical proposal, dry powder is set between first partition and second partition, and liquid carbon dioxide is set
It is placed on the downside of second partition, and dry powder enters the position mixed in delivery pipe with liquid carbon dioxide and is located at first partition or more,
It effectively prevents liquid carbon dioxide to be dropped on dry powder and keep dry powder bonding blocking, prevents liquid carbon dioxide from influencing dry powder
Conveying.
The utility model is further arranged to, arc-shaped, the connection orifice ring of the first partition upper surface middle part recess
The distribution in the middle part of the first partition.
By using above-mentioned technical proposal, the distribution in the middle part of first partition of first partition depression in centre, and intercommunicating pore makes
The liquid carbon dioxide that must be dropped in first partition comes together in the recess in the middle part of first partition, prevents liquid carbon dioxide logical
Intercommunicating pore is crossed to contact with the dry powder on the downside of first partition.
The utility model is further arranged to, and side opening, which is fixed with, on the intercommunicating pore prevents the first partition upper surface
The retaining ring of liquid inflow intercommunicating pore.
By using above-mentioned technical proposal, side opening is fixed with retaining ring on intercommunicating pore, so that being dropped in first partition upper liquid
State carbon dioxide difficultly flows into intercommunicating pore when collecting towards in the middle part of first partition, effectively prevents liquid carbon dioxide and passes through
Intercommunicating pore is contacted with the dry powder on the downside of first partition.
The utility model is further arranged to, and the fan rotated with air-flow is fixed in the intercommunicating pore.
By using above-mentioned technical proposal, when injection valve is open, the high pressure gas on the upside of first partition passes through delivery pipe
It is external with injection valve drain tank, so that the air pressure in first partition is less than the air pressure between first partition and second partition, thus
So that the high pressure gas on the downside of first partition is mingled with dry powder and is discharged by intercommunicating pore in first partition and eventually by delivery pipe
Tank body is discharged, when gas passes through intercommunicating pore, fan rotation, so that the dry powder being mixed in gas is sufficiently and gas mixing, from
And dry powder is spread uniformly in gas, and then improve the extinguishing effect of the fire extinguisher.
The utility model is further arranged to, and the intercommunicating pore is greater than it far from second close to the opening of the second partition
The opening of partition.
By using above-mentioned technical proposal, intercommunicating pore is greater than its opening far from second partition close to the opening of second partition
Mouthful, so that circulation area of the high pressure gas between first partition and second partition when passing through intercommunicating pore reduces, to accelerate
Air-flow velocity at intercommunicating pore, and then improve the velocity of rotation of fan.
The utility model is further arranged to, and the tank wall is fixed with handle.
By using above-mentioned technical proposal, when user uses the fire extinguisher, holds tight handle one for user one and mention
Fire extinguisher is risen, another hand controls injection valve to change injection direction, prevents from causing user to spray because fire extinguisher tank is too heavy
Penetrate inaccurate situation.
