At least two heat dissipation holes 91 are formed in the oxygen generating casing 9, and the two heat dissipation holes 91 are respectively arranged for the heat dissipation fan 53 and the third port 63.
The respirator is also provided with an air pressure sensor, a temperature sensor and a controller, wherein the air pressure sensor is positioned in the air bag 2 and is used for measuring the pressure in the air bag 2; the temperature sensor is positioned in the oxygen generating tank 32 and is used for measuring the temperature of the oxygen generating tank 32 and the oxygen generating agent 321; the controller is used for checking the numerical values of the air pressure sensor and the temperature sensor, is electrically connected with the air pressure sensor and the temperature sensor, and is also electrically connected with the first heat dissipation device 4, the second heat dissipation device 5 and the control end of the control device, namely the controller is also electrically connected with the pump body 42, the heat dissipation fan 53 and the control motor 7.
The implementation principle of the embodiment is as follows: initially, the first port 61 and the second port 62 of the three-way valve 6 are communicated; when the mask cover 1 is worn and a plurality of air (water vapor and carbon dioxide) is blown into the breathing mask 12, the water vapor and the carbon dioxide enter the oxygen generating tank 32 through the first port 61 and the second port 62 of the three-way valve 6 to chemically react with the oxygen generating agent 321 to generate oxygen and heat, on one hand, the oxygen is introduced into the air bag 2, the air bag 2 is expanded, the controller controls the first port 61 to be communicated with the third port 63 through the control motor 7 according to the reading of the air pressure sensor, and the first port 61 is not communicated with the second port 62 to limit the water vapor and the carbon dioxide to continuously enter the oxygen generating tank 32, so that the consumption of the oxygen generating agent 321 is reduced, the generation of heat is reduced, the oxygen is also limited to be discharged from the pressure release valve 21 of the air bag 2, and the waste of the oxygen is reduced; on the other hand, the controller drives the pump body 42 and the heat dissipation fan 53 to operate according to the reading of the temperature sensor, so as to improve the heat dissipation efficiency of the oxygen generation tank 32. So as to reduce the temperature of the oxygen generated by the oxygen generating tank 3 and optimize the experience of oxygen inhalation of human body, thereby improving the experience of using products.
