The exhaust port 221 is provided with a check valve 230, and the check valve 230 flows from the inner edge of the frame 100 to the outer edge of the frame 100. Specifically, the check valve 230 includes a valve flap 231, the valve flap 231 is located inside the exhaust chamber 220, a portion of the valve flap 231 is fixed to the jaw housing 200, and the valve flap 231 covers the outer side 110 of the exhaust port 221. In the embodiment, the valve flap 231 is preferably a thin sheet made of silicone, and one side edge of the valve flap 231 is fixedly connected to the jaw cover 200, but the invention is not limited thereto.

The window covering 300 is a transparent covering, and the window covering 300 is disposed on the outer side 110 of the frame 100. Specifically, the outer edge of the window cover 300 closes the frame 100 and covers the window 101 enclosed in the frame 100. The window cover 300 has a plurality of window hooks 330 at the edge thereof, and the window hooks 330 are respectively fastened to the frame 100 to fix the window cover 300 to the outer side 110 of the frame 100.

In the present embodiment, the inlet 210 and the outlet 220 on the chin cup 200 are both open, and a portion of the window cup 300 covers the chin cup 200 to close the inlet 210 into a closed duct and the outlet 220 into a closed chamber. However, the present invention is not limited thereto, and the air inlet 210 and the exhaust chamber 220 may be formed in the frame 100 in the form of a closed space. Furthermore, the window cover 300 has an air inlet pipe 310 and a port 320, the air inlet pipe 310 is connected to each air inlet 210, and the port 320 is connected to the air outlet 221. Specifically, the intake adapter 310 preferably communicates with the junction of the pair of intake ducts 210.

The rubber ring 400 is used to fit the face 11 of the user 10, and the rubber ring 400 is provided on the inner side 120 of the frame 100 and is disposed opposite to the window cover 300.
