Abstract
The present invention relates to a breathing protection device formed by an oxygen self-help device. The breathing protection device comprises a chemical medical cylinder (1) for generating oxygen, wherein the medical cylinder is arranged in a breathing bag (5) and is sealed wholly. The chemical medical cylinder (1) is covered and fixed on the upper surface of the breathing bag by an insulating sleeve. The design obtains a particularly compact breathing protection device.
Description
The present invention relates to a kind of respiratory protection equipment of oxygen self-rescuer form, especially can be used as and the corresponding to oxygenrespirator of the declaratives of claim 1.
Respiratory protection equipment in the beginning narration is to be contained in airtight closable stocking in the jar, for example, applicable to mine work, is carried by the miner usually.Equipment can be taken off from stock jar during use.
Obviously, such respiratory protection equipment must be light and small and exquisite, because the miner must carry at any time.
In the prior art, similarly respiratory protection equipment is contained in breathing bag above the chemical cartridge case, and chemical cartridge case is located at the bottom of this equipment, and the breathing bag that has respiratory siphon and suction inlet then is contained on the lid of this equipment.Therefore this just requires lid that quite high structural strength is arranged, and has constituted sizable a part of deal of stocking jar, makes respiratory protection equipment and stock and jar must rely on a braces to back on the body.Under the very arduous condition of mine work, it is very uncomfortable that the miner carries it at any time.
So main purpose of the present invention provides a small and exquisite and compact especially design, make an oxygen self-rescuer and mobile respirator can be contained in one and stock in the jar, be loaded on people's the waistband.
The respiratory protection equipment of beginning narration can reach this purpose by the feature that claim 1 provides.
The invention has the advantages that structure size with respiratory protection equipment is reduced to can be contained in equipment little stocking in the jar, and the user can be loaded in it on waistband.Additional advantage is that chemical cartridge case has adopted perfect double-layer seal, that is to say to have adopted sleeve and breathing bag, has reduced the surface temperature of respiratory protection equipment.
Originally the heat that discharges of the imagination chemical cartridge case at work will be to the unallowable burden in addition of inhaled air in breathing bag and the breathing bag, yet the present invention has proved that with the reform of its excellence it is feasible that chemical cartridge case is placed in the breathing bag.But in the former technology, breathing bag will be as far as possible away from the chemical cartridge case that generates heat, in order to avoid the heat that produces increases the load of breathing bag.
Further specializing of advantage of the present invention seen more obviously from dependent claims.
Detail of the present invention provides in the drawings, below for a more detailed description.
Fig. 1 represents a schematic diagram according to the respiratory protection equipment of alternative expression oxygen supply of the present invention.
Fig. 2 is the profile that I-the I line is cut in Fig. 1.
Fig. 3 represents a schematic diagram according to the respiratory protection equipment of closed type oxygen supply of the present invention.
Fig. 4 is placed on a schematic diagram stocking the respiratory protection equipment in the jar according to the present invention.
Fig. 5 is the enlarged detail that indicates the X place in Fig. 4.
Respiratory protection equipment according to a kind of alternative expression oxygen supply of the present invention is shown in Fig. 1.Respiratory protection equipment consists of the following components: an oxygenous chemical cartridge case 1, and it is wrapped tightly by the sleeve 2 of a thermal insulation and damping; A root breath pipe 3 that has suction inlet 4; Be attached at a breathing bag 5 on the chemical cartridge case 1; And carry 6.Fig. 4 has provided one and has been contained in a respiratory protection equipment of stocking in the jar.
A heat exchanger 12 is arranged at the top at the inlet D of chemical cartridge case 1, and it is designed to prevent the thermo-contact between heat exchanger 12 and the chemical cartridge case 1.Heat exchanger 12 is surrounded by the frame cover 17 of a thermal insulation, and this frame cover is fastened the upper surface at chemical cartridge case 1.
There is an opening 5b at upper surface 5a place at breathing bag 5, by this opening chemical cartridge case is injected breathing bag.Opening 5b is surrounded by a reinforcement 5c, the chemical cartridge case 1 of band sleeve 2 and carry 6 end rely on clip 22 be fixed on it above, have heat-insulating cover 23 on the clip 22.A pressure-reducing valve 8 is equipped with at upper surface 5a place at breathing bag 5.
Fig. 2 has provided the profile of the chemical cartridge case 1 that has sleeve 2.Sleeve 2 has some raised line 2a to be spaced and the surface (A) of chemical cartridge case closely cooperates in its vertical direction and/or longitudinal axis direction by certain.
In order utilize to produce the chemicals of oxygen best, allow at the uniform velocity air flow through the space of whole chemicals, so just increased the service life of the respiratory protection equipment in working.This is to do greatly as far as possible circulation area by one to realize, the air that the user the is breathed out respiratory siphon 3 of flowing through enters chemical cartridge case 1, falls vertically from top, and radial from the side ground from outside to inside.Relevant with this, E design in air outlet slit district forms a cover in chemical cartridge case 1.The direction of circulation is represented by arrow.
The topped one deck absorbent cotton 9 of air outlet slit district E pine loose ground enters breathing bag 5 to prevent the chemical powder that is contained in the chemical cartridge case 1.For the chemicals that prevent to melt flow into breathing bag 5 from chemical cartridge case 1, put in the air outlet slit B of cartridge case 1 with an acute angle with a filter screen 10, cover this outlet, and the chemicals of fusing are stayed in the drip trays 11 of chemical cartridge case 1 bottom formation, the path of air is not got clogged.
Fig. 3 has provided the respiratory protection equipment by closed circuit breathing design of the present invention.Its structure is identical with the respiratory protection equipment that Fig. 1 provides, and different just has two outlet valves 18 and heat exchanger 12 on the framework.Framework 13 is pushed, rely on socket be fixed to chemical cartridge case 1 ' inlet D ' locate, that is to say by means of a pipe junctor 19 to be inserted in the pipe socket 20 that is connected on the framework 13 as inlet D '.Rely on sealing gasket 21, socket 20 can be to plug 19 sealings.
Air directly sucks by framework 13 from breathing bag 5, and sleeve 2 provides hole 2b.This makes equipment realize closed circuit breathing.Only breathe out and suction promptly reciprocating type breathing with respiratory siphon 3.The chemistry cartridge case 1 ' airflow direction represent with arrow.
Fig. 4 has represented the respiratory protection equipment in stocking jar.The can body of stocking jar marks by 14, and cover marks by 15.Two parts rely on blocking element (not showing) to force together, and form a hermetic seal, and this all knows in the prior art.Stock on the jar 7 and have iron hoop 16, allow the user will stock jar and be buckled on the waistband.
Respiratory protection equipment in stocking jar 7 must be shockproof.The outstanding round pin 2C that utilization is made on top and each limit of enclosing, bottom of sleeve 2 can realize shockproof well.
Fig. 5 is the zoomed-in view of outstanding circle pin 2C, and it is as chemical cartridge case 1 and stock damper between the wall of jar 7 can body parts 14.
