The utility model can be used for the primary oxygen supply device of the mine chemical oxygen self-saving device and the separate oxygen supply devices of emergency rescue, medical care, etc, under the condition of the oxygen deficient. The utility model has good conducting performance and safe and reliable use, and completely overcomes the existing problem of the prior art.
Description
Technical field
The utility model belong to save oneself, the emergency medical service technical field, exactly be a kind of solid state chemistry thermal response oxygenerator.
Background technology
Utilize solid thermal reaction system oxygen form more at present, but all be to utilize igniter cap, have shortcomings such as complex structure, assembly difficulty are big, start-up temperature height as Starting mode; The applicant discloses in the Chinese patent communique a kind of " solid oxysalt thermal response oxygenerator ", the patent No.: ZL98232746.3.Obtain effect preferably during this patented technology is tested first, but it is confined to piezoelectric ceramics as the percussion power supply; In addition, because the certain defective of original design existence, there were many problems to occur afterwards in the test, be connected with external source as drawing a plain conductor in original design, another electrode is replaced by the metal shell of this device, and for antirust, shell generally will use stainless steel or plate surface material, its poor electric conductivity is so had a strong impact on starting efficiency; Naked light often appears in housing contacts point on the other hand, because this device mainly is used in some particular surroundingss, if there is inflammable gas on every side, then is easy to set off an explosion; In original design, give birth to the oxygen powder column and be with the form of fixing catch up and down and fix powder column, this consolidated form poor stability, fixing catch adopts metallic substance to make in addition, so insulation is difficult to realize to the electrical lead on the priming.Therefore assembling is complicated, not easy to operate, also has the priming district temperature of powder column upper end very high, has a strong impact on the local temperature of shell upper end.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, the one-piece construction of above-mentioned patent application have been done partly to improve, its starting efficiency being improved, and is safe and reliable.
This purpose is to realize with following technical proposal: described solid thermal reaction oxygenerator, it comprises that there is the following capping of taking gas port out of shell, shell lower end, living oxygen powder column is arranged in the shell, there is priming the powder column upper end, described powder column places in the heat insulation medicinal cupping that insulate, medicinal cupping and shell upper end is provided with communicating aperture near the priming place, has two plain conductors to be connected with priming respectively, and its other end is drawn and joined with external percussion power supply from the through hole on medicinal cupping and the shell.Wherein shell is to be that one constitutes by top cover and barrel; Or constitute for two portions socket by top cover and barrel.Described medicinal cupping is to be made of the solid heat-insulating layer; Or connect and compose by solid and software thermofin.Described external percussion power supply is to be made of piezoelectric ceramic ignitor and its bump assembly, or direct current or AC power percussion box device formation.
The utlity model has following advantage: priming adopts two plain conductors to be connected with starting power supply, has overcome the shortcoming that produces naked light with shell as another electrode; Two plain conductors on the priming all can be connected use with extraneous any type of power supply (direct current, interchange or piezoelectric ceramics); employing insulating ceramic jar replaces the metal fixing catch in the above-mentioned patent application; make that powder column is fixed, heat-proof quality good, the power lead that priming is connected plays the insulation protection effect.This oxygenerator starting efficiency height, security is good, and is simple in structure, easily installs.
