Abstract

The invention provides a respirator as well as an oxygen concentration detection device and an oxygen concentration detection method for the respirator. The oxygen concentration detection device for the respirator comprises a transmission pipeline, a selection valve, and an oxygen concentration sensor, wherein the transmission pipeline is used for transmitting gas inside a chassis of the respirator; a first input end of the selection valve is connected with an inhaling pipeline of the respirator, and a second input end of the selection valve is connected with the transmission pipeline; and a first input end of the oxygen concentration sensor is connected to an output end of the selection valve, and the oxygen concentration sensor is selectively connected with the transmission pipeline or the inhaling pipeline through the selection valve, and is used for detecting the oxygen concentration in the transmission pipeline or the inhaling pipeline. The original oxygen concentration sensor used for detecting the oxygen concentration of the inhaling pipeline is adopted to detect the oxygen concentration of the gas inside the chassis to judge whether oxygen-rich air is produced inside the chassis, so the problems of high cost and inconvenient maintenance are solved, and the effect of conveniently and effectively monitoring the oxygen concentration of the gas inside the chassis of the respirator is achieved further.

Description

technical field [0001] The invention relates to a ventilator, an oxygen concentration detection device and a method for the ventilator. Background technique [0002] Currently, when the ventilator is in use, the pipeline oxygen may leak, thereby generating oxygen-enriched air inside the case. This oxygen-enriched air can cause a fire due to the possibility of electrical sparks in electrical circuits. [0003] In order to solve the above problems, there are generally two solutions currently adopted: [0004] 1) Uninterrupted exhaust using a fan [0005] Specifically, most ventilators install a fan on the casing near the place where oxygen is easy to gather, and turn on the fan to exhaust the air when the machine is running. [0006] However, since the actual oxygen concentration of the gas cannot be known, the oxygen concentration may not be effectively controlled due to improper installation of the fan, damage, or insufficient rotation speed. In addition, since the oxyge...
