Description
Technical field
The present invention relates to fire-fighting equipments, more particularly to the positive-pressure air respirator that inflation settles at one go.
Background technology
The positive-pressure air respirator that disappears is a kind of using compressed air as the isolation type respirator of respiratory gas source, used pressure
Contracting air is stored in included storage air bottle（Hereinafter referred to as air bottle）In, plenum system is positive-pressure type, i.e., personnel exhale in wearing
When haustorium is breathed, entire respiratory system always be in be isolated from the outside and internal pressure be higher than ambient pressure environment, exhaling
It is drawn through in journey extraneous toxic and harmful gas to cannot be introduced into inside respiratory system, it is ensured that safe and reliable respiratory protection.The equipment is
It is widely used in fire-fighting, chemical defence, anti-terrorism, locates the various fields such as prominent and emergency management and rescue.
With taking place frequently for China's rapid development of economy in recent years and natural calamity, emergency management and rescue work also show across
Industry, cross-cutting, cross-region complicated development trend.Although China is in Lash-up succor system construction, accident processing and prevents
Model etc. has done a large amount of work, but in all various aspects such as rescue technique tactics research also in the stage at the early-stage, especially
It is that there is also very big gaps with foreign countries for emergency rescue technology equipment Development.How advanced using current rescue team of China shortage,
The existence conditions such as mating rescue outfit carry to the maximum extent the effect of performance these existing weaponry and equipments of positive-pressure air respirator
Height rescue is horizontal, is the top priority of fast lifting rescue team fighting capacity in a short time.Publication No. CN2565465Y's
A kind of existing positive-pressure air respirator is disclosed in patent document, the base basic structure of positive-pressure air respirator includes
The upper end of air bottle, mask and the shoulder harness structure for air bottle to be fixed on to user back, air bottle is equipped with valve.
Existing positive-pressure air respirator has the following disadvantages：When to air bottle bottled gas, for first tank gas then into
Row pressure measurement, bled off if pressure is higher some gases to be depressured, it is relatively low if carry out benefit tank again, namely be difficult to make in air bottle
One step of pressure is canned to meeting the requirements（Usually 3 kilograms）, namely the interior air pressure of air bottle can not be made to settle at one go.
Invention content
The present invention is intended to provide a kind of air pressure being capable of the positive-pressure type air that settles at one go of the primary canned inflation to setting value
Respirator solves the problems, such as that existing positive-pressure air respirator air pressure can not be primary canned to setting value.
The above technical problem is solved by following technical proposal：It is a kind of to inflate the positive-pressure type aerial respiration settled at one go

22.Buffer air bag 23 is equipped in head sections 21.Buffer air bag 23 constitutes the interior surface layers of part of the head sections in addition to leading flank.Neck
Section is flexible structure.Neck section is equipped with neck section Shou San mechanisms 5.There are two neck section Shou San mechanisms and divides along the vertical direction
Cloth.Neck section Shou San mechanisms include unlocking fastening mechanism along the circumferentially distributed hanging ring 51 of neck section, rope and being threaded through suspension
Rope 52 in ring.Air inlet 27 is arranged in the front end of mask 3.The front end of cover body is additionally provided with the check valve 6 for outlet.
Referring to Fig. 4, close up spring 33 and air-breathing drive-type flap opening mechanism 7 equipped with cover board in mask.It is equipped in cover body
With the breathing bag interface 24 of buffer air bag connection.Breathing bag interface is equipped with breathing bag interface cover plate 28.Cover board closes up spring and is used for
Driving breathing bag interface cover plate closes breathing bag interface.Air-breathing drive-type flap opening mechanism is for overcoming the cover board to close up
The elastic force of spring and make breathing bag interface cover plate open.Air-breathing drive-type flap opening mechanism includes cylinder 71,72 and of ripping bar
Balanced plug 73 in cylinder.Ripping bar 72 is hinged on by swivel pin 74 in cover body 31.One end of ripping bar is the same as breathing bag interface
Cover board links together, other end homostasis plug links together.Balanced plug drives the arm of force that ripping bar is moved using swivel pin as shaft rotation
Close up the arm of force that spring driving ripping bar is moved using swivel pin as shaft rotation more than cover board.Cylinder is divided into 711 He of seal chamber by balanced plug
With the atrium 712 of mask connection；When original state, the air pressure of seal chamber and atrium is equal and breathing bag interface cover plate is covering
Plate closes breathing bag interface 24 under the action of closing up spring；Air pressure during use upon inhalation in mask declines to make
The pressure obtained in atrium declines, and the pressure differential balanced plug of seal chamber and atrium is towards atrium movement so that ripping bar
It swings and cover board is overcome to close up the elastic force of spring and breathing bag interface cover plate is opened.When expiration pressure in mask rise from
And so that the pressure in atrium rises, the pressure differential balanced plug of seal chamber and atrium it is mobile towards seal chamber so that
Ripping bar swings and assists cover board to close up spring and the more structurally sound breathing bag interface cover plate breathing bag of breathing bag interface cover plate is connect
On mouth.Breathing bag interface is connected to by communicating pipe 25 with buffer air bag.Communicating pipe is equipped with hand-operated valve 26.
Referring to Fig. 5 and Fig. 6, it includes the arc tube 531 circumferentially extended along annular chamber that rope, which unlocks fastening mechanism 53,.Arc tube
Wall be equipped with the drag-line mobile space 5311 that extends along arc tube extending direction.532 He of link block there are two being set in arc tube
The rubber gas bar 533 extended along ring pipe extending direction between two link blocks.Two link blocks 532 pass through driving two
The link block that a link block closes up closes up spring（It is not drawn in figure）It links together.One end 521 of rope and rope it is another
One end 522 links together with two link blocks correspondingly after intersecting.It further includes control dress that rope, which unlocks fastening mechanism 53,
Set 534.Rubber gas bar is connected with charge and discharge gas port 5331.Charge and discharge gas port is connected to by inflation pump 535 with buffer air bag.
Referring to Fig. 3, Fig. 5 and Fig. 6, control device controls the rope of two neck section Shou San mechanisms according between the time of setting
Every alternately fastening, first make the rope stretch of lower section when specially using and so that neck section contraction tighten neck in user and
It reduces extraneous air to enter headgear and stimulate eyes, makes the rope stretch of top after having crossed the duration of setting and neck section is received
Contracting tightens, and the rope of lower section is unclamped after the rope stretch of top, and the rope stretch of lower section is made after the duration made and is made
Neck section contraction tightens, and the rope of top is unclamped after the rope stretch of lower section, and so cycle is realized and alternately fastened.
Referring to Fig. 6, the process that rope is fastened and unclamped is：It is inflated to aerated rod by inflation pump when tie-down, aerated rod
Inflation heaves and a pair of of link block is driven to separate, and is fastened so that the ring that rope surrounds reduces to realize；It is two-way when release
Inflator pump extracts the gas in aerated rod out, and so that aerated rod is deflated and lose supporting role, closes up the work of spring in link block
Closed up with lower two link blocks so that rope loses tensile force to realize release.
