Respirator capable of prompting replacement of filter towel according to concentration of carbon dioxide

Abstract

The invention relates to the technical field of mining rescue equipment, and provides a respirator capable of prompting replacement of a filter towel according to the concentration of carbon dioxide.The respirator comprises a mining respirator, wherein the top end of the mining respirator is movably connected with a respirator body, and the left side and the right side of the mining respirator are fixedly connected with ventilation equipment through the respirator body. The left side and the right side of the mining respirator are both fixedly connected with pressing columns, and the left side and the right side of the mining respirator are both fixedly connected with carbon dioxide storage tanks. According to the respirator capable of prompting replacement of the filter towel according to the concentration of the carbon dioxide, during replacement of the carbon dioxide and oxygen, the carbon dioxide flows through airflow on the inner sides of the carbon dioxide storage tanks to driveair bags to move rightwards, the air bags push movable frames to move inwards and drive electric leads to move inwards, and the electric leads drive wedging line ends to move towards the middle, so that the wedging line ends are connected and wedged, a circuit is in an on state, and air suction heads are in a working state.

Description

technical field [0001] The invention relates to the technical field of mine rescue equipment, in particular to a respirator that prompts to replace filter towels according to the concentration of carbon dioxide. Background technique [0002] The respirator is a self-contained open air respirator, which has the advantages of light weight, small size, convenient use and maintenance, comfortable wearing, and stable performance. It is especially important in working environments such as mines. It can effectively prevent external Toxic and harmful gases penetrate into the inside of the mask. [0003] When the current mining respirator is in use, during the long-term use, the replacement of the filter towel is not noticed. The filter towel purifies the bacteria in the user's exhaled carbon dioxide. If it is not replaced for a long time, it will cause serious injury. The health of the user, and the currently used mining respirator is a chemical oxygen self-rescue respirator, which...

[0003] When the current mining respirator is in use, during the long-term use, the replacement of the filter towel is not noticed. The filter towel purifies the bacteria in the user's exhaled carbon dioxide. If it is not replaced for a long time, it will cause serious injury. The health of the user, and the currently used mining respirator is a chemical oxygen self-rescue respirator, which will generate a lot of heat and affect the wearer's working status. towel respirator
