Abstract
The invention provides a gas mask. The gas mask comprises a body and a neck sleeve arranged at the bottom end of the body. A big eye widow and a gas defense base are fixedly arranged on the body. A fixing belt is arranged on the two sides of the gas defense base and fixedly provided with an adjusting buckle. A gas defense device is arranged at one end of the gas defense base. A first protective net, a second protective net and a third protective net are fixedly arranged in the gas defense device. An activated carbon layer is fixedly arranged between the first protective net and the second protective net. A sodium oxide layer is fixedly arranged between the second protective net and the third protective net. Airbags are symmetrically arranged on the two sides of the sodium oxide layer. The gas mask is simple in structure, low in making cost, convenient to use and high in practicality. Due to the arrangement of the adjusting buckle, the size of the fixing belt is conveniently adjusted through the adjusting buckle, and people in different sizes can conveniently use the gas mask. Due to the arrangement of the sodium oxide layer, exhalant carbon dioxide and sodium peroxide react to generate oxygen which is stored in the airbags, oxygen inhaled into the human body then passes through the sodium peroxide layer to form oxygen, and therefore the gas mask can be continuously used for gas defense for several days.
Description
Technical field
The present invention relates to a kind of mask, particularly a kind of breathing mask.
Background technology
Breathing mask (gasmask) is individual extraordinary articles for labour protection; also be individual soldier protection articles for use; be worn on the head, protect the respiratory apparatus of people, eyes and face, prevent the personal protection equipment of the noxious material injuries such as poison gas, dust, bacterium, toxic and harmful or steam.Breathing mask is widely used in the fields such as oil, chemical industry, mine, metallurgy, military affairs, fire-fighting, rescue and relief work, health and epidemic prevention and scientific and technological environmental protection, machine-building, and also can play important personal breathing system protection effect in the city that haze, photochemical fog are more serious.Breathing mask can be divided into comprehensive tool and half mask from moulding, and comprehensive tool is divided into again positive-pressure type and suction type.
Breathing mask is mainly made up of parts such as filter element, cover body, eye window, expiration communicator and headbands, their each have their own responsibilities, tacit agreement can coordinate again simultaneously, plays anti-toxic action.
But existing breathing mask tool has the dimensions, be not easy to regulate, the people of correspondingly-sized could must use, use inconvenience, and existing breathing mask mostly is active carbon is lead to carry out gas defence, protection time is short, weak effect.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of breathing mask, be not only provided with adjusting button, the size of breathing mask can be regulated, easy to use, but also be provided with sodium oxide molybdena layer, protection time is long, effective, effectively can solve the problem in background technology.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The invention provides a kind of breathing mask, comprise body and be arranged on the neck cover of described body bottom, described body is fixed with large eye window and gas defence pedestal, the both sides of described gas defence pedestal are provided with fixed band, described fixed band is fixed with adjusting button, one end of described gas defence pedestal is stretched in described body, the other end of described gas defence pedestal is provided with anti-toxic device, described anti-toxic device internal fixtion is provided with the first protection network, second protection network and the 3rd protection network, active carbon layer is fixed with between described first protection network and described second protection network, sodium oxide molybdena layer is fixed with between described second protection network and described 3rd protection network, the bilateral symmetry of described sodium oxide molybdena layer is provided with air bag.
As a preferred technical solution of the present invention, described body and described neck cover are all be made up of flame-retardant cotton material.
As a preferred technical solution of the present invention, the top of described body is provided with illuminating lamp.
As a preferred technical solution of the present invention, the both sides of described large eye window are provided with and are equipped with buckle, are provided with large glasses by described buckle.
As a preferred technical solution of the present invention, described anti-toxic device is made up of stainless steel material, and described anti-toxic device is fixedly connected with described gas defence pedestal by screw thread.
The beneficial effect that compared with prior art the present invention reaches is: structure of the present invention is simple, cheap, easy to use, and it is practical, by being provided with fixed band and fixed band is provided with adjusting button, adjusting button is convenient to the size regulating fixed band, and the people being convenient to different size uses; By being provided with sodium oxide molybdena layer, the carbon dioxide of exhalation and sodium peroxide react and generate oxygen stored in air bag, and the oxygen of inspiration human body, again by sodium peroxide layer, forms oxygen; The present invention can need to be arranged to difference according to difference and need to arrange the size that sodium peroxide arranges, and can be arranged to continuous a couple of days gas defence.
