Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting facilities, and more specifically, particularly relates to an air breathing device. Background Art

[0002] When a fire occurs, thick smoke will be produced. The thick smoke contains a large amount of particulate matter and toxic gases. If improper protection is not provided, the thick smoke can easily be inhaled into the human body, leading to fainting or suffocation. People usually use gas masks to maintain breathing. The gas masks contain filter elements that can filter fine particulate matter and harmful gases, thus blocking the thick smoke from entering the human body.

[0003] The existing application number is: CN201310673286.5. The present invention provides a fire escape breathing filter device, which includes a mask and a filter element, wherein a respirator is arranged inside the mask; an airway is opened in the shell of the respirator, a filter screen is arranged at the front end of the airway, a filter element is placed in the middle of the airway, and a drainage groove is opened in the lower part of the airway; a breathing cavity is opened at the rear part of the shell, and the breathing cavity is communicated with the rear part of the airway through a one-way valve; a water collection chamber is arranged inside the shell, and the water collection chamber is communicated with the drainage groove of the airway through a one-way valve, and the water collection chamber is communicated with the breathing cavity through the one-way valve; a water pipe is arranged inside the shell, and a water distribution plate is arranged at the top of the airway. When personnel wear the fire escape breathing filter device, external air enters the breathing chamber through the filter, airway, filter element and one-way valve in sequence. During this process, the filter filters larger particles in the external air, and the filter element filters and absorbs toxic substances in the external air. When the human body breathes, the liquid in the water collection chamber is sprayed out from the top of the airway along the water pipe. The liquid filters the dust in the air in the airway and reduces the temperature of the air in the airway.

[0004] Based on the above, when using a gas mask for breathing, when the fire in the building is large, the combustion will consume a large amount of oxygen, causing the oxygen content in the building to drop. The gas mask cannot provide more oxygen for the user, which can easily cause the residents in the building to faint due to lack of oxygen, resulting in personal injury to the residents.
