[0020] Example 1

[0021] Please refer to Figure 1-3As shown, this utility model provides an adjustable oxygen mask, including an oxygen mask body 1, a connecting tube 2 connected to the body 1, an adjusting component for adjusting the air intake on the connecting tube 2, the adjusting component including an adjusting tube 3 connected to the connecting tube 2, a fixed plate 4 inside the adjusting tube 3, a turntable 5 inside the adjusting tube 3 and located on one side of the fixed plate 4, a plurality of air inlets 6 on the fixed plate 4, a plurality of air inlets 7 cooperating with the air inlets 6 on the turntable 5, the air intake end of the adjusting tube 3 located on the other side of the turntable 5, and a rotating component for adjusting the angle of the turntable 5 on the adjusting tube 3.

[0022] The main body 1 is a common oxygen mask on the market. The connecting tube 2 is connected to the air inlet of the main body 1. The adjusting tube 3 is connected to the connecting tube 2. The fixed plate 4 is fixed inside the adjusting tube 3. The turntable 5 is located on one side of the fixed plate 4 and can rotate on one side of the fixed plate 4. The first air inlet 6 is opened on the fixed plate 4, and the second air inlet 7 is opened on the turntable 5. There are multiple air inlets 6 and 7. When the first air inlet 6 and the second air inlet 7 are misaligned, the oxygen will be blocked by the fixed plate 4 and the turntable 5. When the first air inlet 6 and the second air inlet 7 overlap, the oxygen can pass through the overlapping part of the first air inlet 6 and the second air inlet 7. When the first air inlet 6 and the second air inlet 7 are completely overlapped, the oxygen flow rate reaches the maximum. With this setting, the oxygen flow rate can be adjusted by simply adjusting the rotation angle of the turntable 5.

[0023] Specifically, the rotating assembly includes a positioning rod 8 connected to the turntable 5, a handle 9 on the adjusting tube 3, a sleeve 10 connected to the handle 9, one end of the handle 9 extending to the outside of the adjusting tube 3, and a spring 11 inside the sleeve 10 that cooperates with the positioning rod 8; a guide groove 12 on the outside of the sleeve 10, and a guide block 13 on the positioning rod 8 that cooperates with the guide groove 12; the positioning rod 8 is fixedly connected to the turntable 5, the handle 9 is rotatably connected to the adjusting tube 3, the sleeve 10 is fixedly connected to the handle 9, a mechanical seal is used between the handle 9 and the adjusting tube 3, the spring 11 is located inside the sleeve 10, and the spring 11 enables the turntable 5 to be stably attached to the fixed plate 4; the guide groove 12 is opened on the side wall of the sleeve 10, and the guide block 13 is fixedly connected to the positioning rod 8; the sleeve 10 and the positioning rod 8 are anti-rotationally engaged, which facilitates the adjustment of the angle of the turntable 5, thereby facilitating the adjustment of the oxygen inlet speed.
