[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] See also Figure 1-3 , the utility model provides a technical solution: an oxygen supply mask for plateau working environment, comprising a mask body 1 with a multi-layer structure and a retractable strap 2;

[0021] The two ends of the telescopic band 2 are respectively fixedly connected to the two ends of the mask body 1, the rear end of the outer surface of the telescopic band 2 is fixedly connected to the device box 6, the inside of the device box 6 is fixedly connected to the gas cylinder 11, the outer surface of the gas cylinder 11 is connected to the air supply pipe 4, the upper part of the front end surface of the mask body 1 is fixedly connected to the air intake frame 5, and the other end of the air supply pipe 4 passes through the side surface of the device box 6 and the outer layer of the telescopic band 2 and extends to the inner layer of the interlayer of the telescopic band 2;

[0022] The outer end of the air supply pipe 4 extends to the outside of the air intake frame 5 through the inner part of the interlayer of the telescopic strap 2 and the mask body 1 and is communicated with the inner part of the air intake frame 5 .

[0023] In this embodiment, the device can be worn directly on the face when in use. After wearing, the device box 6 is used to connect to the oxygen vest. Then, the oxygen in the oxygen vest will enter the gas cylinder 11 inside the device box 6, and then enter the interior of the air intake frame 5 through the air supply pipe 4 connected to the gas cylinder 11. The air intake frame 5 is located at the nose area of ​​the face, so the oxygen delivered through the air supply pipe 4 can be directly absorbed by people, ensuring the smooth delivery of oxygen.

[0024] Since the mask body 1 is a multi-layer structure, the air supply pipe 4 can extend inside the interlayer of the mask body 1. This structure can be used to fix the air supply pipe 4 to prevent the air supply pipe 4 from being exposed to the outside of the mask body 1, which can also provide protection.

[0025] Furthermore, the bottoms of both ends of the mask body 1 are fixedly connected with reinforcement straps 3 , and the other ends of the two reinforcement straps 3 are fixedly connected to the lower surface of the telescopic strap 2 .

[0026] In this embodiment, the two reinforcing straps 3 can play a reinforcing effect, and reinforce the connection of the retractable strap 2, so as to ensure that the strap will not be disconnected when the device is worn, thereby ensuring the quality of the device.

[0027] Furthermore, a humidifier bottle 7 is fixedly connected to the inside of the device box 6 and located on one side of the gas cylinder 11, a connecting pipe 12 is connected between the top of the humidifier bottle 7 and the gas cylinder 11, and a device hole is opened horizontally through the outer surface of the device box 6, and an air inlet pipe 8 is fixedly connected to the inside of the device hole, and one end of the air inlet pipe 8 passes through the humidifier bottle 7 and extends to the bottom end thereof.

[0028] In this embodiment, there is pure water inside the humidifier bottle 7, and the highest position of the pure water is located in the middle of the inner cavity of the humidifier bottle 7. The outer end of the air inlet pipe 8 is directly connected to the oxygen vest. The oxygen in the oxygen vest enters the interior of the humidifier bottle 7 through the air inlet pipe 8. After the oxygen enters the interior of the humidifier bottle 7, it will enter the pure water, and then float from the pure water into the top of the top of the humidifier bottle 7, and then enter the gas cylinder 11 through the connecting pipe 12 and finally be inhaled by people. In this process, the oxygen can be moistened by the pure water to prevent people from inhaling dry oxygen and causing discomfort.

[0029] The gas cylinder 11 plays a transitional role, preventing the purified water from being sucked into the human body through the air supply pipe 4.

[0030] Furthermore, the other end of the air inlet pipe 8 extends to the outside of the device box 6 through the device hole, a connector 10 is fixedly connected to the outer surface of the air inlet pipe 8 and located outside the device box 6, and a one-way valve 9 is provided inside the air inlet pipe 8 and located inside the humidification bottle 7.

[0031] In this embodiment, the one-way valve 9 can prevent the purified water from flowing back into the oxygen vest through the air inlet pipe 8 .

[0032] Furthermore, one end of the air supply pipe 4 and the interior of the air intake frame 5 is connected to a telescopic hose 13 .

[0033] An annular airbag 14 is fixedly connected to the outer surface of the other end of the telescopic hose 13 .

[0034] In this embodiment, when people breathe oxygen, if they want to ensure the purity of the inhaled oxygen, they can insert the other end of the telescopic hose 13 into the nose. At this time, the oxygen can be completely inhaled into the human body through the telescopic hose 13, and the annular airbag 14 can play a fixing role to prevent the telescopic hose 13 from falling off in the nasal cavity of people.

[0035] The working principle and use process of the utility model: after the utility model is installed, when the device is in use, since the main body of the device is the mask body 1, it is more convenient to wear. When in use, the device box 6 is connected to the oxygen cylinder or the oxygen vest, and the oxygen will enter the interior of the gas cylinder 11. Then, the oxygen is sent to the air intake frame 5 at the front end of the mask body 1 of the device through the air supply pipe 4 connected to the gas cylinder 11. The position of the air intake frame 5 is located at the nose part of the face. The oxygen entering the air intake frame 5 will be directly inhaled by people, so as to ensure the smooth delivery of oxygen. A humidifying bottle 7 is also arranged inside the device box 6 of the device. The humidifying bottle 7 has pure water inside, which can humidify the oxygen to prevent the wearer from inhaling dry oxygen and causing adverse reactions.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
