[0034] Example 1

[0035] In some embodiments, please refer to the appendix of the specification. Figure 1-8 An aviation oxygen supply mask body with a matching composite valve includes a mask 1, the mask 1 including a mask body 11, a sound transmission hole 12 and a breathing hole 13, the sound transmission hole 12 is opened on the front end surface of the mask body 11, and the breathing hole 13 is opened on the lower side of the front end of the mask body 11;

[0036] The front end of the mask body 11 is located at the sound transmission hole 12 and is equipped with a detachable sound transmission component 2 for talking, and the breathing hole 13 is connected to a detachable breathing component 3 for the wearer to breathe;

[0037] The detachable breathing assembly 3 includes a position-limiting and disassembling assembly 31 and a breathing assembly 32 . The position-limiting and disassembling assembly 31 is connected to the breathing hole 13 , and the breathing assembly 32 is detachably connected to the position-limiting and disassembling assembly 31 .

[0038] The mask 1 further includes a first protective cover 14 , which is fixedly mounted on the lower front end of the breathing hole 13 and is disposed at the breathing hole 13 .

[0039] When the present invention is used, a detachable sound transmission component 2 is detachably mounted at the sound transmission hole 12 of the mask body 11, thereby facilitating maintenance and disassembly of the communication function;

[0040] The wearer's exhalation and inhalation devices are integrated into one through the breathing assembly 32, and the breathing assembly 32 and the mask body 11 are quickly disassembled and assembled through the limited disassembly assembly 31;

[0041] The detachable sound transmission component 2 includes a connecting ring 21, a microphone 22, a second protective cover 23, a limiting sleeve 24 and a sealing ring 25. The connecting ring 21 is fixedly mounted on the front end surface of the mask body 11 and is concentrically arranged with the sound transmission hole 12. The microphone 22 is slidably connected to the inner wall of the connecting ring 21. One end of the microphone 22 is used in cooperation with the front end surface of the mask body 11. The second protective cover 23 is threadedly connected to the connecting ring 21. The limiting sleeve 24 is slidably connected to the front end through hole of the second protective cover 23. The other end of the microphone 22 is used in cooperation with the end ring of the limiting sleeve 24. A sealing ring 25 is embedded between the end slide of the limiting sleeve 24 and the inner top of the second protective cover 23.

[0042] When the present invention is in use, the microphone 22 is placed in the connecting ring platform 21 and is threadedly connected to the connecting ring platform 21 through the second protective cover 23. The second protective cover 23 protects the microphone 22. At the same time, the second protective cover 23 drives the limiting sleeve 24 to contact the microphone 22 while threadedly engaging with the connecting ring platform 21 and firmly limits the microphone 22. The elastic deformation of the sealing ring 25 between the end ring platform of the microphone 22 and the inner top of the second protective cover 23 allows the microphone 22 to be squeezed by the limiting sleeve 24 and buffered, thereby avoiding damage to the microphone 22 caused by excessive pressure. At the same time, the sealing effect of the sealing ring 25 can prevent dust from entering and affecting the noise of the microphone 22.

[0043] The limiting and disassembling assembly 31 includes a limiting block 311 and a disassembling ring 312. The limiting block 311 is horizontally arranged and fixedly mounted on the inner wall of the breathing hole 13.

The disassembling ring 312 cooperates with the inner wall of the mask body 11 for use;

[0044] The breathing assembly 32 includes a main body 321, an exhaust hole 322, an air inlet hole 323, a breathing valve 324, a connecting boss 325 and a limiting groove 326. The rear end face of the main body 321 cooperates with the outer wall of the mask body 11 for use. The rear end of the main body 321 is fixedly installed with a connecting boss 325 for use in conjunction with the breathing hole 13. The exhaust hole 322 and the air inlet hole 323 are opened on the rear side wall of the connecting boss 325 and pass through the main body 321. The exhaust hole 322 is located above the air inlet hole 323. The rear end face of the connecting boss 325 is provided with a limiting groove 326 for use in conjunction with the main body 321. The disassembly ring 312 is detachably connected to the connecting boss 325. The breathing valve 324 is fixedly installed at the front end of the main body 321 and is located at the exhaust hole 322.

[0045] The connecting boss 325 is threadedly connected to the disassembly ring 312 .

[0046] An air supply pipe is detachably connected to the inner wall of the front end of the air inlet 323 .

[0047] The front inner wall of the air inlet hole 323 is threadedly connected to the air supply pipe.

[0048] When the present invention is used, the first protective cover 14 is installed on the mask body 11 to protect the breathing assembly 32, thereby preventing the breathing assembly 32 from falling off due to an emergency during flight and affecting flight safety.

[0049] When the present invention is used, the exhaust hole 322 and the air inlet 323 are arranged on the main body 321, the exhaust hole 322 is connected to the breathing valve 324, and the connecting boss 325 is connected to the air supply pipe, thereby realizing the integrated setting of the exhalation structure and the inhalation structure;

The disassembly ring 312 is threadedly connected to the outer wall of the connecting boss 325. The disassembly ring 312 contacts the inner wall of the locking mask body 11, and the main body 321 contacts the outer wall of the locking mask body 11, thereby realizing the rapid disassembly and assembly of the breathing assembly 32.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
