Description

Technical Field

[0001] The utility model relates to the technical field of oxygen supply masks, and particularly relates to a dual-channel oxygen supply mask. Background Art

[0002] An oxygen supply mask is a life-saving device in case of emergencies. It can provide sufficient oxygen supply to users in case of emergencies, avoiding the loss of consciousness of users due to lack of oxygen and ensuring their life safety.

[0003] For example, the Chinese utility model patent CN220877555U discloses an escape self-oxygen supply mask. The circular gasket is detachably connected to the circular groove of the magnetic base, so that oxygen leakage will not occur between the first ventilation port and the second ventilation port.

[0004] However, it still has the following drawbacks. When the device provides oxygen, due to the too small through holes opened on the flow indicator, it may be impossible to accurately collect the pressure fluctuations in the mask cavity.

[0005] Based on this, the utility model designs a dual-channel oxygen supply mask to solve the above problems. Summary of the Utility Model

[0006] In view of the above-mentioned shortcomings of the prior art, the utility model provides a dual-channel oxygen supply mask.

[0007] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0008] A dual-channel oxygen supply mask includes a mask, on which a dual-channel component for providing oxygen is installed, and the dual-channel component is connected to a joint component;

[0009] The dual-channel component includes a flow indicator component, a communication component and an oxygen supply component. The mask is connected to the flow indicator component and the communication component, and the flow indicator component is connected to the oxygen supply component;

[0010] The joint component is fixedly connected to the oxygen supply component.

[0011] Furthermore, the flow indicator component includes a tee joint, a first air pipe, a second air pipe, a through hole, a flow indicator, a first movable block, a second movable block and a spring. The tee joint is clamped at the front end of the mask. The lower end of the tee joint is fixedly connected to the first air pipe. The lower end of the first air pipe is fixedly connected to the flow indicator. The lower end of the flow indicator is fixedly connected to the second air pipe. The second air pipe is connected to the oxygen supply component. One end of the spring is fixedly connected to the inner top of the flow indicator, and the other end of the spring is fixedly connected to the first movable block. The first movable block and the second movable block are slidably connected in the flow indicator. The first movable block is located above the second movable block. Through holes are opened on both the first movable block and the second movable block.

[0012] Further, the tee joint is connected to the oxygen supply component.

[0013] Further, the communication component includes a barometric pressure detector and a power connector. The barometric pressure detector is fixedly connected to the front end of the face mask, and the power connector is fixedly connected to the lower end of the barometric pressure detector.

[0014] Further, the oxygen supply component includes a long air pipe, an air pipe three, a connecting block one, a pipe connector, an inner pipe and a fixing block. The lower end of the air pipe two is fixedly connected to the connecting block one, the lower end of the connecting block one is fixedly connected to the fixing block, the pipe connector is fixedly connected inside the fixing block, the lower end of the fixing block is fixedly connected to the air pipe three, the lower end of the pipe connector is fixedly connected to the inner pipe, the inner pipe is connected to the joint component, the upper end of the pipe connector is fixedly connected to the long air pipe, and the upper end of the long air pipe is fixedly connected to the tee joint.

[0015] Further, the air pipe three is connected to the joint component.

[0016] Further, the joint component includes a double-layer pipe, a circlip, a connecting block two and a gasket. The lower end of the air pipe three is fixedly connected to the outer pipe of the double-layer pipe, the inner pipe of the double-layer pipe is fixedly connected to the inner pipe, the connecting block two is fixed to the outer wall of the double-layer pipe by the circlip, the lower end of the double-layer pipe is fixedly connected to the gasket, and the connecting block two is connected to an external oxygen supply device.

[0017] Further, a clamping groove for clamping and fixing is formed at the lower end of the connecting block two.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] In the embodiment of the present utility model, when the device starts to be installed, the flow indicator of the flow indicator assembly connects the first air pipe and the second air pipe. At the same time, the first connecting block of the oxygen supply assembly fixes the fixing block and the third air pipe on the second air pipe. When the device starts to supply oxygen, the gas flows into the second air pipe through the third air pipe. The gas in the second air pipe flows out of the flow indicator through the through holes formed in the first movable block and the second movable block to complete the detection of the gas flow rate in the pipeline. When the gas pressure is too high, it presses the first movable block and the second movable block to move upward along the inner wall of the flow indicator. At the same time, the upward movement of the first movable block presses the spring to contract. At this time, the gas can flow out through the gap between the flow indicator and the second movable block to reduce the pressure in the pipeline. At the same time, the gas flows into the long air pipe through the inner pipe and the pipe connector. The gas in the long air pipe flows into the face mask through the three-way joint. At the same time, the power supply connector of the communication component supplies power to the air pressure detector so that the air pressure detector can detect the air pressure fluctuation in the face mask. By supplying corresponding oxygen to the face mask, it is avoided that due to the too small middle through hole of the flow indicator in the oxygen supply pipeline, the oxygen supply device cannot accurately collect the pressure fluctuation of the face mask, and thus cannot reasonably supply oxygen with an appropriate concentration to the face mask. At the same time, by timely feedback of the measured pressure, the pressure in the face mask can be adjusted to avoid discomfort to the user caused by too large air pressure changes. If the middle through hole of the flow indicator is too large, it cannot effectively cause a pressure difference between the upper and lower parts of the through hole and cannot play a flow indicating role.

The lower end of the flow indicator 215 is fixedly connected to the second air pipe 213. The second air pipe 213 is connected to the oxygen supply assembly 23. One end of the spring 218 is fixedly connected to the inner top of the flow indicator 215, and the other end of the spring 218 is fixedly connected to the first movable block 216. The first movable block 216 and the second movable block 217 are slidably connected in the flow indicator 215. The first movable block 216 is located above the second movable block 217. Through holes 214 are formed in both the first movable block 216 and the second movable block 217;

[0037] The communication assembly 22 includes a barometric pressure detector 221 and a power supply connector 222. The barometric pressure detector 221 is fixedly connected to the front end of the face mask 1.

[0038] The oxygen supply assembly 23 includes a long air pipe 231, a third air pipe 232, a first connecting block 233, a pipe connector 234, an inner pipe 235, and a fixing block 236.

The upper end of the long air pipe 231 is fixedly connected to the tee joint 211;

[0039] In the embodiment of the present utility model, when the device starts to be installed, the flow indicator 215 of the flow indicator assembly 21 connects the first air pipe 212 and the second air pipe 213. At the same time, the first connecting block 233 of the oxygen supply assembly 23 fixes the fixing block 236 and the third air pipe 232 on the second air pipe 213. When the device starts to supply oxygen, the gas flows into the second air pipe 213 through the third air pipe 232. The gas in the second air pipe 213 flows out of the flow indicator 215 through the through holes 214 formed in the first movable block 216 and the second movable block 217 to complete the detection of the gas flow rate in the pipeline. When the gas pressure is too high, it presses the first movable block 216 and the second movable block 217 to move upward along the inner wall of the flow indicator 215. At the same time, the upward movement of the first movable block 216 presses the spring 218 to contract. At this time, the gas can flow out through the gap between the flow indicator 215 and the second movable block 217 to reduce the pressure in the pipeline. At the same time, the gas flows into the long air pipe 231 through the inner pipe 235 and the pipe connector 234.

At the same time, the power supply connector 222 of the communication component 22 supplies power to the air pressure detector 221 so that the air pressure detector 221 can detect the air pressure fluctuation in the mask 1. By supplying corresponding oxygen to the mask 1, it is avoided that due to the too small middle through hole 214 of the flow indicator 215 in the oxygen supply pipeline, the oxygen supply device cannot accurately collect the pressure fluctuation of the mask 1, and thus cannot reasonably supply oxygen with an appropriate concentration to the mask 1. At the same time, by timely feedback of the measured pressure, the pressure in the mask 1 can be adjusted to avoid discomfort to the user caused by too large air pressure changes. If the middle through hole 214 of the flow indicator 215 is too large, it cannot effectively cause a pressure difference between the upper and lower parts of the through hole 214 and cannot play the role of indicating the flow.

[0040] A joint assembly 3 is installed and fixedly connected to the mask 1, and the joint assembly 3 is connected to the dual-channel assembly 2;

[0041] The joint assembly 3 includes a double-layer pipe 31, a snap ring 32, a second connecting block 33 and a sealing gasket 34.
