Mask oxygen can protect important organs such as heart, brain and lungs from damage caused by hypoxia, and can be used for patients of different age groups, whether infants, children or adults, can provide suitable oxygen supply.

[0003] However, most of the oxygen masks have the following problems:

[0004] For example, the oxygen mask with publication No. 202222658803.9 can deliver oxygen through the connected oxygen delivery pipe, but the pipe size of the oxygen delivery pipe is fixed, and the amount of oxygen delivered is fixed. Different wearers need different amounts of oxygen, and too much or too little oxygen will affect the oxygen absorption effect. It is not convenient to adjust the flow of oxygen according to the use condition. At the same time, the elastic band can adjust the tightness through the magic tape, but the length of the magic tape is fixed during adjustment. Different users have different head circumference sizes, and the size is too small to be firmly worn, and the size is too large to be used, affecting the use effect, and it is not convenient to adjust and use according to the size of the user's head circumference.

[0005] Therefore, we improve it and propose a flow adjustable oxygen mask. UTILITY MODEL CONTENTS
