Problems solved by technology

[0002] At present, when the roadheader is working, especially when the rock tunnel is excavated, a large amount of dust will be generated, which will endanger the breathing function of the operator, and even seriously affect the health of the excavator. Therefore, a respiratory system with a mask is required
In the prior art, the air supply pressure of the traditional breathing system is not very stable and needs to be constantly adjusted, which not only reduces the work efficiency, but also may affect the health of the operator; on the other hand, the traditional breathing system is not positive pressure, so It cannot prevent dust and other hazardous substances from entering the mask, which will be inhaled by the operator and cause harm

Abstract

The invention discloses a positive pressure respiratory system, comprising a filtering device, a water tank, an air supply valve and a face mask, which are connected through pipelines in sequence. The positive pressure respiratory system is simple in structure and convenient to use, and enables a user to breath more comfortably; and besides, outside harmful gas is prevented from entering the respiratory organ of the user, and the application safety factor is high.

Description

technical field [0001] The invention relates to a dust-proof breathing system, in particular to a positive pressure breathing system. Background technique [0002] At present, when the roadheader is working, especially when the rock tunnel is excavated, a large amount of dust will be generated, which will endanger the breathing function of the operator, and even seriously affect the health of the excavator. Therefore, a respiratory system with a mask is required. In the prior art, the air supply pressure of the traditional breathing system is not very stable and needs to be constantly adjusted, which not only reduces the work efficiency, but also may affect the health of the operator; on the other hand, the traditional breathing system is not positive pressure, so It cannot prevent dust and other hazardous substances from entering the mask, which will be inhaled by the operator and cause injury. Contents of the invention [0003] The purpose of the present invention is to...
