DETAILED DESCRIPTION

[0019] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0020] In the embodiment of the present application, the bottom of the mask body 1 is integrally provided with a fixing groove 2, a positioning disc 9 is rotatably installed in the inside of the fixing groove 2, an oxygen delivery pipe 7 is sleeved in the inside of the positioning disc 9, an oxygen delivery disc 12 is communicated with the top of the oxygen delivery pipe 7, two supporting slide rods 5 are fixed on one side of the oxygen delivery disc 12, one end of the two supporting slide rods 5 penetrates and extends out of the inside of the positioning disc 9, a rotating disc 6 is fixed on one end of the supporting slide rods 5, a spring 11 is sleeved on the outside of the supporting slide rods 5, an air inlet disc 14 is fixed on the top of the inside of the fixing groove 2, a plurality of air inlets 13 are formed on one side of the air inlet disc 14, a plurality of air outlet pipes 15 are fixed on one side of the air inlet disc 14 at equal intervals, the air outlet pipes 15 are communicated with the air inlets 13, an air outlet insertion pipe 16 is welded on one side of the oxygen delivery disc 12, and the air outlet insertion pipe 16 is communicated with the inside of the oxygen delivery disc 12.

[0021] Specifically, as shown in FIG. 1, Figure 1 , Figure 2 and Figure 4As shown, when in use, the mask body 1 is worn at the mouth and nose of the patient, then one end of the oxygen supply pipe 7 is communicated with the oxygen tank, the oxygen enters the inside of the oxygen supply disc 12 through the oxygen supply pipe 7, and then flows out through the gas outlet pipe 16 in the inside of the oxygen supply disc 12. By connecting the gas outlet pipe 16 with the gas inlet 13 at different positions, the concentration of the oxygen flowing out can be changed. When adjusting the concentration of the oxygen output, the oxygen supply pipe 7 is pulled outward, and when the oxygen supply pipe 7 is pulled, the oxygen supply disc 12 moves in the inside of the fixed groove 2. Since the two supporting slide rods 5 are fixed on one side of the oxygen supply disc 12 and slide through the inside of the positioning disc 9, when the oxygen supply disc 12 is pulled, the gas outlet pipe 16 is pulled out of the inside of one gas inlet 13, and at the same time, the spring 11 outside the supporting slide rod 5 is compressed. When the gas outlet pipe 16 is pulled out of the inside of one gas inlet 13, the positioning disc 9 and the oxygen supply disc 12 are rotated in the inside of the fixed groove 2 by rotating the rotating disc 6. By rotating the oxygen supply disc 12, the gas outlet pipe 16 can be moved to the side of another gas inlet 13. Then, the pulling of the oxygen supply pipe 7 is cancelled. At this time, the compressed spring 11 rebounds to push the oxygen supply disc 12 to move towards the side of the gas inlet disc 14, so that the gas outlet pipe 16 is inserted into the inside of another gas inlet 13. Since one gas outlet pipe 15 is communicated with each gas inlet 13 on one side, and the diameters of each gas outlet pipe 15 are different, the concentration of the oxygen output can be adjusted by selecting gas outlet pipes 15 with different diameters. The rebounding force of the spring 11 can ensure that the gas outlet pipe 16 is always located in the inside of the gas inlet 13, avoiding the situation that the gas outlet pipe 16 falls out of the gas inlet 13, causing the oxygen to be unable to output. At the same time, it ensures that the oxygen concentration does not change due to the shaking of the patient's head when the patient wears the mask body 1 to inhale oxygen, improving the treatment effect on the patient.

[0022] In example 2, the bottom of the fixed groove 2 is provided with a through hole 8, and one end of the two supporting slide rods 5 extends out of the inside of the fixed groove 2 through the through hole 8. The inner wall of the fixed groove 2 is provided with a sliding groove 10, and the outer side of the positioning disc 9 is fixed with a sliding block 4 which is slidingly installed in the inside of the sliding groove 10. The diameter of the gas outlet pipe 16 is smaller than that of the gas inlet 13, and the gas inlet 13 and the gas outlet pipe 16 are cooperatively installed. There are six gas outlet pipes 15, and the diameters of the six gas outlet pipes 15 are reduced in a stepped manner clockwise. The top ends of the plurality of gas outlet pipes 15 extend into the inside of the mask body 1, and the side of the mask body 1 is fixed with a fixing belt 3. The oxygen supply pipe 7 is slidingly installed in the inside of the positioning disc 9, and the bottom end of the oxygen supply pipe 7 extends out of the inside of the rotating disc 6.

[0023] Specifically, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, since the bottom of the fixed groove 2 is provided with a through hole 8, the support slide rod 5 can extend out of the inside of the fixed groove 2 through the through hole 8, and when the rotating disc 6 is rotated, the positioning disc 9 and the oxygen delivery disc 12 can be driven to rotate in the inside of the fixed groove 2. Since the inner wall of the fixed groove 2 is provided with a sliding groove 10, and the outer side of the positioning disc 9 is fixed with a sliding block 4 which is slidingly installed in the inside of the sliding groove 10, therefore, when the positioning disc 9 rotates in the inside of the fixed groove 2, the sliding block 4 will slide along the opening direction of the sliding groove 10, thereby ensuring the stability of the rotation of the positioning disc 9. Since the number of the gas outlet pipes 15 is six, the flexibility of the oxygen concentration adjustment is improved. Since the side of the mask body 1 is fixed with a fixing belt 3, the mask body 1 can be fixed at the mouth and nose of the mask body 1 through the fixing belt 3.

[0024] Working principle: when in use, the mask body 1 is worn at the mouth and nose of the patient, the fixing belt 3 is placed outside the occiput of the patient by winding around the head of the patient, the mask body 1 is fixed at the mouth and nose of the patient, then one end of the oxygen delivery pipe 7 is communicated with the oxygen tank, the oxygen enters the inside of the oxygen delivery disc 12 through the oxygen delivery pipe 7, and then flows out through the gas outlet cannula 16 in the inside of the oxygen delivery disc 12. By connecting the gas outlet cannula 16 with the gas inlet 13 at different positions, the outflow concentration of the oxygen can be changed. When adjusting the oxygen output concentration, the oxygen delivery pipe 7 is pulled outward, which drives the oxygen delivery disc 12 to move in the inside of the fixed groove 2, and when the oxygen delivery disc 12 is pulled, the gas outlet cannula 16 is pulled out of the inside of one gas inlet 13, and the spring 11 outside the support slide rod 5 is compressed. By rotating the rotating disc 6, the positioning disc 9 and the oxygen delivery disc 12 can be rotated in the inside of the fixed groove 2. By rotating the oxygen delivery disc 12, the gas outlet cannula 16 can be moved to the side of another gas inlet 13. Then the pulling of the oxygen delivery pipe 7 is cancelled. At this time, the compressed spring 11 rebounds, thereby driving the oxygen delivery disc 12 to move towards the side of the gas inlet disc 14, so that the gas outlet cannula 16 is inserted into another gas inlet 13. Since one gas outlet pipe 15 is communicated with each gas inlet 13, and the pipe diameters of each gas outlet pipe 15 are different, therefore, by selecting the gas outlet pipe 15 with different pipe diameters, the output concentration of the oxygen can be adjusted, and the rebound force of the spring 11 can ensure that the gas outlet cannula 16 is always located in the inside of the gas inlet 13.

[0025] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
