[0023] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.

[0024] Example 1

[0025] like Figure 1-Figure 5 As shown, this embodiment provides a breathing mask with a detachable bite 2, comprising a mask body 1, a bite 2 and a push-stop block 3.

[0026] The mask body 1 is formed with four hooks 13 arranged in a matrix on its outer surface. These hooks 13 are used to connect to the elastic cord. The mask body 1 is formed with an outwardly extending connection platform 15 on its periphery. The connection platform 15 has an interface 11 and an air inlet 12. The air inlet 12 is located above the interface 11 and is used to connect to the trachea. The interface 11 is elliptical in shape. Sliding grooves 14 are formed on both sides of the interface 11. The bottom of the sliding groove 14 is formed with a retaining groove 141 on both sides. The retaining groove 141 contains a guide post 142.

[0027] The bite 2 is elliptical in shape and will be limited after being inserted into the interface 11. A limiting ring 21 is provided on the outside of one end of the bite 2. The bite 2 is adapted to the interface 11 and extends into the interface 11. The limiting ring 21 is located outside the mask body 1.

[0028] The bite 2 and the interface 11 are detachably connected. A block extending toward the interface 11 is formed at the end of the push-stop block 3. The distance from the lower surface of the block to the connecting platform 15 is equal to the thickness of the retaining ring 21. The bottom of the push-stop block 3 is located in the sliding groove 14, where it is locked and slidably connected. A spring 143 is provided between the push-stop and the sliding groove 14. Specifically, limit blocks 31 are formed on both sides of the lower end of the push-stop block 3. The limit blocks 31 have matching holes 311, through which the guide posts 142 pass. The spring 143 is located between the limit blocks 31 and the side walls of the retaining groove 141.

[0029] Principle of assembly and disassembly: When installing the bite 2, push the two pushing blocking blocks 3 outward, then insert the bite 2, release the pushing blocking blocks 3 after they are in place, and under the action of the spring 143, push the blocking blocks 3 to reset, and push the lower surface of the blocking block 3 against the upper surface of the column limiting ring 21. At this time, the bite 2 is positioned. When it needs to be removed, push the two pushing blocking blocks 3 outward and pull out the bite 2.

[0030] Example 2

[0031] Figure 6-Figure 8 As shown, the difference between this embodiment and embodiment 1 is that the detachable structure is different. Long strip-shaped threaded holes are formed on both sides of the connecting platform 15. The breathing mask also includes two screw pins 4. The circumference of the screw pin 4 has an external thread, and the external thread is adapted to the threaded hole. The length of the screw pin 4 is greater than the length of the threaded hole. The ratio of the length of the screw pin 4 to the length of the threaded hole is three to two. The screw pin 4 is located outside the threaded hole to form a cylinder, and the circumference of the cylinder is a rough surface. The circumference of the bite 2 has through holes 22 on both sides, and the through holes 22 correspond to the threaded holes.

[0032] Principle of assembly and disassembly: First, insert the bite 2 into the interface 11 until the limit ring 21 hits the connecting platform 15, then start to rotate the cylindrical rough surface of the rotary pin 4. The rotary pin 4 moves inward under the action of the thread until the end of the rotary pin 4 extends into the through hole 22. At this time, the bite 2 is installed. Rotate the rotary pin 4 in the opposite direction to make the end of the rotary pin 4 extend out of the through hole 22. At this time, the bite 2 can be pulled out.

[0033] Preferably, the through holes 22 on both sides of the circumference of the bite 2 are changed into pits, and the through holes 22 are replaced by pits. The pits have a limiting function. When the rotating column 4 hits the pit, the rotating column 4 cannot be rotated, which means that the rotating column 4 is screwed into place.

[0034] The above shows and describes the basic principles and main features of the invention and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the utility model. Without departing from the spirit and scope of the invention, the utility model will have various changes and improvements, and these changes and improvements will fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
