Abstract
The utility model provides a life-saving gas mask which is composed of an oxygen producing agent (1), a container (2), a face mask (3), a diaphragm (4) and a fastening belt (5), wherein, the oxygen producing agent (1) is a chemical substance which can generate oxygen with the carbon dioxide exhaled by people. The oxygen producing agent (1) and the container (2) are arranged in the face mask (3), the oxygen producing agent (1) is sealed by the diaphragm (4), and the fastening belt (5) is arranged on the face mask (3). When the utility model is used, the diaphragm (4) is removed, the face mask is worn on people's face, and thus oxygen can be generated for people to breathe. The life-saving gas mask can be widely used for various occasions which are short of oxygen and hard to breathe, such as dealing with an emergency, life saving, rescuing emergency patients, etc., and has the advantage of convenient and safe use.
Description
The utility model relates to a gas mask, in particular to a gas life-saving mask capable of generating oxygen.
The gas mask is generally produced and used at home and abroad, the first kind is that oxygen or air is filled in a storage device and is conveyed to a mask through a pipeline for breathing, and the second kind is that the air is conveyed to the mask through a carbonization tank filled with an adsorbentand is conveyed to the mask through a pipeline for breathing after being filtered. The first respirator is inconvenient to use because of the weight and complex structure of the respirator, and needs high pressure to store gas, and the second respirator can only filter a few toxic gases, so the respirator cannot be widely applied.
The novel gas mask is designed aiming at the defects of the prior gas mask, does not need a high-pressure storage device and a pipeline, does not need any filtering device, and generates oxygen for breathing by the oxygen generating agent in the mask and carbon dioxide exhaled by people.
The utility model discloses a realize like this: the utility model consists of a face mask, an oxygen producing agent, a container, a diaphragm and a binding belt. The mask has the main function of protecting the face to form a breathing chamber, and the oxygen generating agent and carbon dioxide exhaled by a person act in the breathing chamber to generate oxygen for the person to breathe. Storing the oxygen-making agent in a container. The diaphragm plays the role of sealing the oxygen-making agent, and the tightening belt tightly joints the mask and the face of a person to form a closed breathing chamber. The cover is made of metal, rubber (or plastic) and other materials. The oxygen producing agent is chemical matter capable of producing oxygen by the action of carbon dioxide, such as: sodium peroxide and the like, the oxygen generating agent is encapsulated in the face mask by a diaphragm, the diaphragm is removed when the mask is used, and the working principle of using the sodium peroxide as the oxygen generating agent is as follows:
compared with the prior gas mask, the utility model has the advantages of convenient use, light safety body and low cost, and can be widely applied to diving, aviation and petrochemical industries, and the occasions of various oxygen deficit and breathing difficulty such as mines, mountaineering, first aid, fire escape and rescue. After the oxygen generating agent is renewed, the gas-defense life-saving mask can be repeatedly used.
The attached drawing is a section view of the gas-defense life-saving mask provided by the utility model.
The specific structure of the present invention is further described in detail by the following embodiments and the accompanying drawings. 1-oxygen producing agent 2-container 3-face mask 4-diaphragm 5-binding band
The oxygen production agent (1) is arranged in the container (2) and then arranged in the face mask (3), and the oxygen production agent (1) is a chemical substance (such as sodium peroxide and the like) which can generate oxygen with carbon dioxide exhaled by a person. The oxygen producing agent (1) can be one or a compound of two or more chemical substances which can generate oxygen with carbon dioxide exhaled by a person, the face mask (3) is made of metal rubber (or plastics) and other materials, the oxygen producing agent (1) and the container (2) are arranged in the face mask (3), the oxygen producing agent (1) is sealed by a diaphragm (4), when in use, the diaphragm (4) is removed, the face mask (3) is worn on the face of the person to be aligned with the oral cavity, and a rubber product binding belt (5) is arranged on the face mask (3) to enable the gas-defense life-saving mask to be tightly jointed with the face of the person. Can be used for breathing of people, and the oxygen-making agent (1) is renewed after use, and can be reused.
Claims (3)
1. An anti-gas life-saving mask mainly comprises an oxygen generating agent (1), a container (2), a face mask (3), a diaphragm (4) and a binding belt (5), and is characterized in that the oxygen generating agent (1) and the container (2) are arranged in the face mask (3), and the oxygen generating agent (1) is sealed by the diaphragm (4).
2. The gas mask of claim 1 wherein: the oxygen production agent (1) is a chemical substance which can generate oxygen with carbon dioxide exhaled by people.
3. The gas mask of claim 1 wherein: the oxygen producing agent (1) may be one or two or more chemical compounds capable of producing oxygen with carbon dioxide exhaled by human body.
