Abstract
The utility model provides a novelstructure isolated-type positive pressure oxygen breathing apparatus which comprises an oxygen bottle assembly, a pressure reducer assembly, an airbag assembly, a cleaning tank assembly, a cooling device assembly, a breathing hosepipe and a shell. The novelstructure isolated-type positive pressure oxygen breathing apparatus is characterized in that a cooling device shell is arranged on the cooling device assembly, and ventilation holes are installed on two sides of the cooling device shell and an upper cover of the cooling device shell. A corrugated pipe is assembled in the cooling device shell. An air inlet end of thecorrugated pipe is connected with an airbag, and an air outlet end of the corrugated pipe is connected with the breathing hosepipe. A bearing spring is arranged between a bearing plate and a crossbeam which are arranged in the airbag assembly. A clamping jaw is disposed on circumference of a spring seat, and the bearing spring is fixed on the clamping jaw in a clamping mode. The novelstructure isolated-type positive pressure oxygen breathing apparatus has the advantages that a cooling device adopts structure design of a corrugated metal pipe, and surface area of heat exchange is increased. When a person inhales, high temperature airflow from a low pressure system carries out the heat exchange through the surface area of the corrugated pipe to reduce suction temperature. Tedious operations offilling ice cakes, freezing ice cakes and pouring out ice water solution after use in an original cooling device are replaced. The spring seat adopts a clamping jaw structure, and is simple in structure, and enables installation of springs to be stable and reliable.
Description
Technical field
The utility model belongs to the isolation type positive pressure oxygen respirator of the protective device, particularly a kind of new construction of self respiratory system that uses in a kind of rescue.
Background technology
Isolation type positive pressure oxygen respirator (hereinafter to be referred as " oxygen is exhaled ") is the isolated respirator of a kind of and ambient atmosphere, when the rescue team member that it is widely used in mine rescue team member, fire fighter, chemical industry unit and subterranean tunnel is engaged in rescue work in the pernicious gas environment to the protection of himself respiratory system.Because the operating environment temperature is very up to more than 40 ℃ sometimes, add the CO of calcium hydroxide and people's exhalation in peace and quiet jar in " oxygen is exhaled "
2Reaction produces big calorimetric, and the team member is difficult to stand, and design one cooler in " oxygen is exhaled " is equipped with ice cube in the cooler for this reason, is used for reducing the temperature that sucks air-flow.But when the rescue environment temperature is not high, as: the rescue environment does not have breaking out of fire, only is that coal gas is arranged, or causes anoxic after the gas explosion, and chemical industry unit rescues poison gas and reveals or the like, still adopts this cooler just unsuitable.Weightening finish is bigger because this cooler must use ice block cooling, needs freezing equipment, brings a lot of inconvenience.Design the cooling structure of other form, the needs that satisfy in normal temperature rescue environment are one of current problems that need to be resolved hurrily.
In malleation " oxygen is exhaled "; In order to keep remaining the barotropic state that is higher than external atmospheric pressure in the low-pressure system, on air bag, be provided with a bearing plate, the bearing plate top is provided with crossbeam and is fixed on the lower casing; Crossbeam and bearing plate correspondence up and down are designed with spring base, are used to install bearing spring.Along with the user exhales with air-breathing, the air bag band bearing plate and is moved up or down, and a year spring is also done corresponding amoeboid movement thereupon and come barotropic state in the maintenance system.Because operating environment is complicated, during rescue, it is unavoidable bumping, so on the bearing plate spring base, deviate from just to lose barotropic state because of bump carries spring sometimes.Though a lot of units have taked different measure from design, because of complex structure, make troubles to loading and unloading, designing therefore that spring base simple in structure, easy to loading and unloading meets consumers' demand also is one of current problem that will solve.
Summary of the invention
The utility model purpose is to provide a kind of isolation type positive pressure oxygen respirator of new construction, realizes the high temperature gas flow heat exchange through the corrugated metal pipe of high surface area, and good cooling effect reduces relying on the troublesome operation that ice block cooling brought; Simple in structure, after packing into, spring is difficult for deviating from, and safe and reliable.
The utility model purpose realizes through following technical scheme: it comprises oxygen cylinder assembly, pressure reducer assembly, air bag component, peace and quiet canister assembly, chiller assembly, breathing hose and housing; It is characterized in that: chiller assembly is provided with cooler casing; Cooler casing both sides and loam cake are provided with passage; Assembling bellows in the cooler casing, bellows air inlet end connects air bag, and bellows gas outlet end connects breathing hose; Between bearing plate in air bag component and the crossbeam bearing spring is set, is positioned on the circumference of spring base claw is set, bearing spring clamps on the claw that is fixed on spring base.
The utility model has the advantages that: cooler is adopted corrugated metal tubular type structural design, increase the surface area of heat exchange, the people makes when air-breathing from high temperature gas flow in the low-pressure system when getting into bellows, carries out heat exchange to reduce suction temperature through surface area.Replaced former cooler load ice cube, freezing ice cube, with after pour out the troublesome operation of water ice solution.Spring base is adopted the jack catchs type structure, and simple structure makes spring solid and reliable.。

The specific embodiment
See Fig. 1-6; Concrete structure is following: the utility model adopts prior art that oxygen cylinder assembly 1, pressure reducer assembly 7, peace and quiet canister assembly 4, breathing hose 5 and housing 2 are set; Improved technical essential is: chiller assembly 6 is provided with cooler casing 15; Cooler casing 15 both sides are provided with strip passage 14, and cooler casing loam cake 13 is provided with round vent 12, the spiral metal bellows 18 of assembling in the cooler casing 15; Spiral metal bellows 18 air inlet ends 11 connect air bag 22 through interface 19, and spiral metal bellows 18 gas outlet ends 16 connect breathing hose 5 through interface 17; Rubber seal 10 is set in the junction, prevents to manage interior gas leak.Air bag 22, bearing plate 9 and crossbeam 20 are set in air bag component 6; Between bearing plate 9 and crossbeam 20, bearing spring 8 is set; Be positioned on the circumference of spring base 23 three claws that are uniformly distributed with 21 are set; Bearing spring 8 clamps on the claw 21 that is fixed on spring base, and spring base 23 is plastic products, is injected into one with bearing plate 9 (working of plastics).
