Background
The fire hazard is a great danger for human beings, causes great personnel and property loss, consumes a large amount of oxygen, generates toxic gas and smoke dust, causes human bodies to be inexperienced or even syncope and die, and the conventional common tool for fire fighting is a gas mask, but has single function and is inconvenient to use.
In order to solve the problems, the patent application with the application number of CN201120211486.5 discloses an oxygen supply gas defense device for fire rescue, which consists of an oxygen generating device, a gas guide pipe and a gas defense mask, wherein the oxygen generating device is connected with the gas defense mask through the gas guide pipe; the oxygen generating device consists of an oxygen generating agent storage tank, a catalyst bag, an oxygen generating chamber and a filter chamber; sodium percarbonate (chemical formula: 2Na2CO 3.3H 2O2) is arranged in the oxygen producing agent storage tank, the opening of the tank is sealed by aluminum foil and is screwed on an upper connector of the oxygen producing chamber through threads; the catalyst bag is filled with manganese dioxide powder; the oxygen producing chamber and the filtering chamber are made into a whole and separated by a partition plate; the upper part of the clapboard is connected with a breather pipe, and the other end of the breather pipe extends to the bottom of the filter chamber; the upper part of the filter chamber is connected with an air duct. When the oxygen generating device is used, a proper amount of water is added into the oxygen generating chamber and the filtering chamber, then the catalyst in the catalyst bag is poured into the water in the oxygen generating chamber, sodium percarbonate in the oxygen generating agent storage tank falls into the oxygen generating chamber, a large amount of oxygen is generated under the action of the catalyst under the action of the water, the oxygen is introduced into the bottom of the water in the filtering chamber through the vent pipe on the upper part of the partition plate, pure oxygen is formed after the water is filtered, and the oxygen is input into the gas mask through the gas guide pipe on the upper part of the filtering chamber for people to use.
The device has the advantages of convenient material acquisition, low raw material price, high reaction speed of generating oxygen, capability of effectively filtering harmful gas in air and winning more time for fire rescue work.
However, the device is disposable, and the aluminum foil cannot be repaired after being punctured; in addition, after the aluminum foil is punctured, sodium percarbonate falls into the oxygen generation chamber from the oxygen generation agent storage tank, once the reaction is started, the reaction can only wait for the end of the reactant, and the reaction can not be started or stopped as required; and finally, the ventilating pipe is arranged on the partition plate, so that the water in the oxygen making chamber and the water in the filtering chamber can shake violently due to violent movement in fire scene rescue, and the water can possibly slow oxygen generation.
Disclosure of Invention
The invention aims to provide an oxygen supply gas defense device which is flexible in starting and stopping and can be used repeatedly, aiming at the defects in the prior art.
The invention is realized by the following technical scheme:
the utility model provides a open and stop nimble oxygen suppliment anti-virus device that repetitious usage, includes oxygenerator and gas mask through the air duct connection, oxygenerator includes the system oxygen room, the system oxygen room is split into reacting chamber and filter chamber by middle part baffle, and shown system oxygen room top is equipped with sealed lid, the sealed lid at reacting chamber top is connected with the reagent room, be equipped with the reagent ball that has the aperture in the reagent room, put sodium percarbonate in the reagent ball, the reagent ball includes upper hemisphere and lower hemisphere through threaded connection, upper hemisphere top is connected with the telescopic link, the telescopic link runs through and sets up at the reagent room top, lower hemisphere below is equipped with the drainage platform, the drainage platform below is equipped with the sealing post, the sealing post diameter with the reagent room internal diameter is the same, reagent room lateral wall is connected with the breather pipe, the other end setting of breather, the upper part of the filter chamber is connected with an air duct.
When the device is used, the telescopic rod is extended to enable the reagent ball to enter water in the reaction chamber, the sodium percarbonate reacts with the water to generate oxygen, the oxygen enters the filter chamber from the ventilating pipe on the side wall of the reagent chamber and then enters the air duct, and the device is stopped to be used. Shorten the telescopic link, in reagent ball, the sealed column got back to the reagent room, the sealed column sealed with the mouth of pipe of ventilating of reagent room lateral wall just, cut off reaction liquid and filtrate, prevented both exchanges, the sealed column keeps apart reaction room and reagent room, prevents that sodium percarbonate from weing, when needing to change sodium percarbonate, will seal the lid and open, the extension telescopic link, open the reagent ball can.
Above-mentioned drainage platform is hemisphere or conical, and when the telescopic link shortened, drainage platform can leave rapidly, prevents that water from being sealed at reagent indoor.
The sealing plate is arranged below the sealing column, the diameter of the sealing plate is larger than that of the sealing column, and the sealing plate can seal a gap between the sealing column and the reagent chamber.
The oxygen generating chamber is provided with braces.
The reagent chamber is also internally provided with a drying agent box for preventing the sodium percarbonate from generating oxygen due to moisture.
Above-mentioned telescopic link is for cutting the fork, and convenient to use and displacement are great.
