[0015] In order to make the technical means for realizing the utility model, creative features, objectives and effects easy to understand, the utility model is further explained below in conjunction with specific diagrams. In the description of the utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.

[0016] Example 1

[0017] like Figure 1-3The high-concentration oxygen mask shown in the figure includes a mask 1, an oxygen storage bottle 3, a ventilation cover 4, an oxygen supply tube 5, a connector 15 and an inhaler 11. The ventilation cover 4 is connected to the mask 1. A plurality of ventilation holes 14 are provided on the ventilation cover 4. When a user breathes, he or she inhales oxygen and exhales other gases such as carbon dioxide. The exhaled gas is released into the air through the ventilation holes 14 to prevent a large amount of gas from accumulating in the mask 1 and causing oxygen blockage. One end of the inhaler 11 is connected to the mask 1, and the connector 15 is connected to the other end of the inhaler 11. The other end of the connector 15 is detachable. An oxygen supply tube 5 is connected, and the other end of the oxygen supply tube 5 is detachably connected to the oxygen storage bottle 3. Both ends of the oxygen supply tube 5 are made of soft PVC material, and the middle part of the oxygen supply tube 5 is made of hard PVC material. Both ends of the oxygen supply tube 5 can be bent to facilitate the connection of the oxygen supply tube 5 with the oxygen storage bottle 3 and the connector 15. An emergency oxygen supply component that automatically inhales air when the oxygen supply is insufficient is provided on the oxygen supply tube 5. A safety component that improves the safety of oxygen delivery is provided on the oxygen supply tube 5. The middle part of the oxygen supply tube 5 is harder and can support the emergency oxygen supply component and the safety component to maintain the stability of its operation.

[0018] In this embodiment, the emergency oxygen supply component includes a filter 6, an air pump 7, an air intake valve 9, an air intake pipe 10 and an oxygen detector 13. One end of the air intake pipe 10 is connected to the oxygen supply pipe 5, and the other end of the air intake pipe 10 is connected to the air pump 7. The top of the air pump 7 is connected to the filter 6. The filter 6 is filled with an adsorbent that can adsorb impurities and moisture in the air. The air intake valve 9 is connected to the inner wall of the air intake pipe 10, and the oxygen detector 13 is connected to the inner wall of the oxygen supply pipe 5. The oxygen detector 13 is installed below the air intake pipe 10. When the oxygen detector 13 detects that the oxygen concentration in the oxygen supply pipe 5 is too low, the air pump 7 and the air intake valve 9 will be opened. The air pump 7 will filter the air through the filter 6 and then inhale it into the oxygen supply pipe 5, so that when the mask cannot provide enough oxygen in time, the user can still be supplied with oxygen by inhaling air, thereby preventing the user from facing suffocation due to lack of oxygen.

[0019] Furthermore, it also includes a rubber pad 2, which is connected to the mask 1. The rubber material fits the human face better, making the user more comfortable when wearing it and having better sealing.

[0020] Example 2

[0021] A further improvement on the basis of Example 1 is that Figure 2 The high concentration oxygen mask shown in the figure has a safety component including a pressure gauge 8 and a pressure reducing valve 12, which are installed on the oxygen supply pipe 5. The pressure reducing valve 12 cooperates with the pressure gauge 8 to monitor the oxygen pressure in the oxygen supply pipe 5 in real time when in use and can quickly reduce the pressure when the pressure is too high, thereby improving the safety performance of the mask 1.

[0022] The process flow and working principle of the utility model are as follows: when in use, the mask 1 is first worn on the mouth and nose, the oxygen pressure is monitored in real time through the reading of the pressure gauge 8, the oxygen pressure is controlled by the pressure reducing valve 12 to reach the optimal pressure, and the excessive oxygen pressure is prevented from causing damage to the user, and then the oxygen content in the oxygen supply pipe 5 is monitored by the oxygen detector 13. When the oxygen content is low or the oxygen supply is interrupted, the air pump 7 and the air inlet valve 9 are turned on, and the air pump 7 sucks air into the oxygen supply pipe 5 through the filter 6. After the air is filtered by the filter 6, the oxygen content therein will increase, and air can continue to be supplied to the user in the case of oxygen interruption, so as to avoid the user from facing suffocation due to lack of oxygen, and the safety performance of the user during use is improved.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
