[0065] When used, the specific steps are as follows:

[0066] Step 1: Thread the second hollow tube 43 into the first hollow tube 42 until the first hollow tube 42 and the second hollow tube 43 are at a suitable length, that is, when the housing 10 is worn on the face, the rubber tube 44 can be held in the mouth;

[0067] Step 2: Using a headband, the person wears the housing 10 on the face, and the side of the housing 10 facing the face is tightly fitted to the face of the person using a sealing ring; since wearing with a headband and sealing with a sealing ring are prior arts, they are not described in detail in the present invention;

[0068] Step 3: When a person inhales, negative pressure is generated in the first hollow tube 42 and the second hollow tube 43. When negative pressure is generated in the first hollow tube 42 and the second hollow tube 43, negative pressure is generated in the inner cavity of the cylinder 30 through the air outlet pipe 40. When negative pressure is generated in the inner cavity of the cylinder 30, negative pressure is generated in the first air inlet pipe 20 through the first pipe 21. When negative pressure is generated in the first air inlet pipe 20, air is caused to flow into the cylinder 3 through the first air inlet pipe 20 and the first pipe 21. 0, after the air flows into the cylinder 30, the air will pass through the second filter 35 and the activated carbon 36 and flow into the other side of the inner cavity of the cylinder 30. In this process, the dust in the air will be filtered by the second filter 35 and the activated carbon 36, and the filtered air will flow into the first hollow tube 42 through the outlet pipe 40. After the air flows into the first hollow tube 42, it will flow into the human body through the second hollow tube 43 and the rubber tube 44 to achieve inhalation.

[0069] Step 4: When a person exhales, the exhaled gas will flow into the first hollow tube 42 and the second hollow tube 43. When the gas flows into the first hollow tube 42 and the second hollow tube 43, the one-way valve 41 will cause the gas to flow into the exhaust pipe 45 to squeeze the sealing plate 46. When the sealing plate 46 is squeezed, the length of the third hollow tube 47 and the solid rod 48 will become longer, and the spring 49 will also deform until the sealing plate 46 and the exhaust pipe 45 are separated. When the sealing plate 46 and the exhaust pipe 45 are separated, the exhaled gas It will flow into the shell 10 and be discharged through the vent 492 to realize exhalation. In this process, when the exhaled gas flows into the shell 10, it will be sensed by the carbon dioxide sensor 491. After the carbon dioxide sensor 491 senses it, the outside air will flow into the second air intake pipe 50 through the fan 51. After the air flows into the second air intake pipe 50, it will flow into the cylinder 30 through the second pipe 52 and the first pipe 21 for pre-filtration, so that it can be inhaled into the human body during the next inhalation, thereby increasing the amount of air during the next inhalation.
