[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] like Figure 2 , 3 As shown in Figures 5 and 6, the trigger assembly 2 includes a diaphragm 21, a piston 22, a seal 23, and an elastic element 24. For example, the piston 22 is made of a metal material with a certain strength, specifically copper that meets medical-grade requirements; the diaphragm 21 has specific requirements for its hardness and is made of medical-grade vapor-phase silicone; and the elastic element 24 is a spring. A first mounting groove 51 is formed at the connection between the cover 1 and the outer shell 3. The diaphragm 21 is disposed within the first mounting groove 51. An annular snap-fit ​​structure 21a is provided below the diaphragm 21, and a corresponding protruding annular snap-fit ​​structure is provided at the center of the outer shell 3. The diaphragm 21 and the outer shell 3 are connected through the snap-fit ​​structure, forming a third gas chamber 43, allowing the oxygen source to... Gas is fully introduced into the mask for user use. The diaphragm 21 is fitted around the piston 22, and the piston 22 is located at the center of the diaphragm 21. The axis of the piston 22 coincides with that of the diaphragm 21. The piston 22 is provided with a large end 22a and a small end 22b. The large end 22a is provided with a second mounting groove 52. The elastic element 24 is provided in the second mounting groove 52 between the mask body 1 and the large end 22a of the piston. The small end 22b of the piston is provided with a third mounting groove 53. The sealing element 23 is fixedly provided in the third mounting groove 53 of the small end 22b of the piston. The piston 22 and the oxygen inlet 31 are sealed and connected by the sealing element 23.

[0036] like Figure 2 As shown, the cover 1 is provided with multiple air intake holes 11 and exhaust holes 12; the outer shell 3 is provided with an oxygen inlet 31.

[0037] like Figure 3 As shown, a first air chamber 41 is formed between the diaphragm 21 and the cover 1; two chambers are formed between the diaphragm 21 and the outer shell 3, with the diaphragm buckle 21a as the boundary: the outer side of the diaphragm buckle 21a is the second air chamber 42, and the inner side of the diaphragm buckle 21a is the third air chamber 43.

[0038] like Figure 2 , 3 As shown in Figures 5 and 6, piston 22 is provided with a first channel 22c, a second channel 22d, and a third channel 22e;

[0039] One end of the first channel 22c is connected to the second mounting groove 52, and then to the first air chamber 41 and the air intake hole 11, while the other end is connected to the second channel 22d.

[0040] One end of the second channel 22d is connected to the first channel 22c, and the other end is connected to the third gas chamber 43, which in turn is connected to the oxygen inlet 31. For example, the second channel 22d includes four circular channels arranged at 90-degree intervals on the circumference of the piston 22.

[0041] One end of the third channel 22e is connected to the third mounting groove 53 where the seal 23 is located, and the other end is connected to the second channel 22d. It is used to vent air during seal installation, so that the seal can be installed easily.

[0042] like Figure 2 As shown, the outer casing 3 has multiple air vents 32 on its side, which are used to balance the air pressure in the second air chamber 42 when the diaphragm 21 moves. When the air pressure in the second air chamber 42 is less than the atmospheric pressure, ambient air enters the second air chamber 42 through the air vents 32; when the air pressure in the second air chamber 42 is greater than the atmospheric pressure, the air in the second air chamber 42 is discharged through the air vents 32.

[0043] like Figure 1 As shown, the cover 1 and the outer shell 3 are connected and fixed by multiple buckles, or they can be connected and fixed by any of the following methods: ultrasonic welding, extrusion and welding.

[0044] like Figure 1-7 As shown, the present invention relates to a breathing mask with oxygen-saving function, and its specific working method and principle are as follows:

[0045] This utility model relates to a breathing mask with oxygen-saving function. It mainly controls the opening and closing of the oxygen passage at the oxygen inlet through a trigger component 2, achieving synchronous pulse oxygen supply during breathing and thus saving oxygen. The diaphragm 21 in the trigger component 2 is made of soft rubber and is fitted onto the outer periphery of the piston 22. It can drive the piston 22 to move according to the user's exhalation and inhalation, thereby controlling the sealing state between the piston's small end seal 23 and the oxygen inlet 31. The diaphragm 21 and the piston 22 are simultaneously subjected to three forces: the elastic force of the elastic element 24, the negative / positive pressure generated by inhalation / exhalation, and the gas pressure from the gas source.

[0046] When an external gas source is connected to the oxygen inlet 31, the diaphragm 21 and piston 22 are subjected to the elastic force of the elastic element 24 and the gas pressure of the gas source, so that the piston seal 23 and the oxygen inlet 31 are in a sealed state, and the overall oxygen passage is closed.

[0047] When the user inhales, the diaphragm 21 and piston 22 are subjected to the negative pressure generated by the inhalation, causing the piston seal 23 to move away from the oxygen inlet 31, thus disengaging from the oxygen inlet 31. At this time, the entire oxygen passage is open. Figure 4As shown, the gas source enters the third gas chamber 43 through the oxygen inlet 31, flows through the second channel 22d and the first channel 22c into the first gas chamber 41, and enters the cover 1 through the air intake hole 11 to achieve the oxygen supply function.

[0048] When the user finishes inhaling and enters the exhalation state, the positive pressure generated by exhalation on the diaphragm 21 and piston 22 causes the piston seal 23 to move closer to the oxygen inlet 31, restoring the seal with the oxygen inlet 31. At this time, the entire oxygen passage returns to the closed state. Figure 3 As shown, exhaled air is discharged through the exhaust port 12 provided on the cover 1, thus completing the synchronous triggering of pulse oxygen supply function for one breath and achieving the oxygen-saving effect.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
