[0039] When using this device, by covering the user's mouth and nose with the fixed cover 8, the air outlet pipe 7 is drawn in, which in turn drives the connecting pipe 5 to draw in the air. The connecting pipe 5 draws in the air storage tank 4, and oxygen enters the connecting pipe 5 from the inside of the air storage tank 4, enters the filter pipe 6 from the inside of the connecting pipe 5, and enters the air outlet pipe 7 from the inside of the filter pipe 6, making it convenient for the user to use.

[0040] When oxygen enters the filter tube 6, the filter element 12 filters the oxygen. The gas drives the cleaning ring 14 to move. The cleaning ring 14 can rotate by the cooperation of the ball bearing 16 and the moving rail groove 13, so that the cleaning brush 15 cleans the surface of the filter element 12 in all directions. The filtered oxygen enters the outlet pipe 7 from the inside of the filter tube 6, which can effectively filter and purify the oxygen and prevent impurities inside the oxygen from harming the user's health.

[0041] By manually opening the control valve 20 outside the injection tube 18, lithium bromide is injected into the injection tube 18 and enters the cooling box 17 from inside the injection tube 18. The cooling pipe 21 cools the lithium bromide, and the cooled lithium bromide cools the connecting pipe 5, thus effectively cooling the oxygen and improving the practicality of the respirator.
