[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0027] A laminar flow oxygen supply hood with a regulating valve, such as Figure 1-Figure 10 As shown, it includes an oxygen mask 1, a support ring 2, a sealing cushion 3, an air inlet 4, an air outlet 5, an adjustment port 6, a sliding base 7, an adjustment block 8, a rotating frame 9, a gear set 10 and a rotating handle 11. The upper inner side of the oxygen mask 1 is connected to the support ring 2, and the support ring 2 is made of soft elastic material to improve the comfort of the user. The oxygen mask 1 is made of transparent material for easy observation by the user. The lower inner side of the oxygen mask 1 is connected to the sealing cushion 3, and the sealing cushion 3 is made of elastic rubber material. The upper middle side of the oxygen mask 1 is connected to the air inlet 4, and the left side of the sealing cushion 3 is connected to the air outlet 5. The upper part of the adjusting port 6 is sleeved, and the lower part of the air outlet 5 is also sleeved with the adjusting port 6. The inner side of the middle part of the adjusting port 6 is connected with a sliding base 7. Six adjusting blocks 8 are slidably connected to the sliding base 7. The inner side of the upper part of the adjusting port 6 is rotatably connected with a rotating frame 9. The adjusting blocks 8 are in contact with and matched with the adjacent rotating frames 9. The rotating frame 9 is provided with six guide grooves for guiding the adjusting blocks 8. The outer side of the middle part of the adjusting port 6 is rotatably connected with a rotating handle 11. The rotating handle 11 is provided with anti-slip grooves for easy rotation. A gear set 10 is connected between the rotating handle 11 and the adjacent rotating frame 9.

[0028] When using the present invention, first move the device into the oxygen cabin, then put the oxygen supply mask 1 on the head of the person to be supplied with oxygen, so that the support ring 2 is in contact with the person to be supplied with oxygen, so that the support ring 2 supports the device, and because the sealing cushion 3 is made of elastic rubber material, it can be easily put on the head of the person to be supplied with oxygen and at the same time it will be tightly attached to the neck position of the person to be supplied with oxygen, so that the inside of the oxygen supply mask 1 is airtight. After the oxygen supply mask 1 is fixed on the head of the person to be supplied with oxygen, the sliding bases 7 on the air inlet 4 and the air outlet 5 are respectively connected to the oxygen supply pipeline in the oxygen cabin, so that oxygen can flow evenly from the air inlet 4 into the oxygen supply mask 1 for oxygen supply, and a stable laminar airflow is formed inside the hood, and the laminar airflow can effectively prevent particles and pollutants in the oxygen from entering the patient's respiratory tract, thereby To ensure that the oxygen inhaled by the patient is clean and safe, since the oxygen chamber is a high-pressure environment and the air pressure is greater than the pressure inside the oxygen supply mask 1, the exhaust gas of the oxygen-inhaling person will be discharged from the air outlet 5 under the action of negative pressure. During the oxygen supply process, the rotating handle 11 can be rotated, and the rotating frame 9 can be rotated through the meshing movement of the gear set 10, and then the adjusting block 8 can be contacted and matched with the rotating frame 9 to make the adjusting block 8 slide and open on the sliding base 7, so that the size of the opening between the adjusting blocks 8 can be adjusted, and the oxygen flow and pressure can be flexibly adjusted according to the actual situation of different oxygen-inhaling people to achieve the best oxygen supply effect, which makes it comfortable to wear and provides sufficient oxygen supply, improves the user experience, and can accurately adjust the oxygen supply flow to improve the oxygen supply effect.
