[0025] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0026] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0027] Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The respiratory mask shown has a quick-detachable inner and outer filtering mechanism, including a transparent mask body 1, a circular assembly hole 2 is opened at the lower front end of the transparent mask body 1, a front filter cover shell 3 is provided at the front end of the transparent mask body 1 at the outer opening position of the circular assembly through hole 2, an internal respiratory mask 4 is provided inside the transparent mask body 1 at the inner opening position of the circular assembly through hole 2, and the assembly end of the front filter cover shell 3 has an internal guide assembly tube 5 protruding into the inside of the circular assembly through hole 2.

[0028] In order to facilitate installation and internal filtering, a plurality of arc-shaped assembly and installation grooves 6 with open upper ends are provided on the inner side surface of the pre-filter housing 3 , and a detachable filter module 7 is inserted into the arc-shaped assembly and installation grooves 6 .

[0029] In order to cooperate with assembly and rotation locking, the outer arc surface of the internal guide assembly tube 5 has an integral curved locking strip 8, and the assembly surface of the internal breathing mask 4 is provided with an internal assembly through hole that cooperates with the internal guide assembly tube 5, and the inner arc surface of the internal assembly through hole has an arc-shaped locking strip 9 that cooperates with the curved locking strip 8.

[0030] The internal breathing mask 4 is sleeved on the internal assembly through-hole on the internal flow guide assembly tube 5, and then the arc-shaped locking strip 9 is first inserted from both sides of the curved locking strip 8 in an offset manner, and then the internal breathing mask 4 is manually rotated, and the curved locking strip 8 is squeezed from one side through the arc-shaped locking strip 9, which will prompt the internal flow guide assembly tube 5 to drive the pre-filter cover shell 3 to only fit and be fixed on the outer side of the transparent mask body 1, closing the circular assembly through-hole 2.

[0031] In order to improve the sealing performance of the assembly surface, an external assembly sealing frame 10 is fixedly assembled on the assembly surface of the pre-filter housing 3 located at the periphery of the internal flow guide assembly pipe 5 .

[0032] In order to facilitate control, the layout angle of the upper end opening of the arc-shaped assembly installation groove 6 inside the pre-filter housing 3 is staggered.

[0033] In order to cooperate with filtering and sealing, the detachable filter module 7 includes an assembly sealing frame 71 inserted into the arc-shaped assembly mounting groove 6, an arc-shaped sealing cover 72 fixed on the outer arc surface of the assembly sealing frame 71, an adjustment sealing frame 73 movably installed on one side of the assembly sealing frame 71, and a metal filter 74 fixed inside the assembly sealing frame 71 and the adjustment sealing frame 73.

[0034] The filter holes of the metal filter mesh inside the assembly sealing frame 71 and the adjustment sealing frame 73 are controlled in size by rotating and adjusting, thereby adjusting the air flow.

[0035] In order to facilitate manual adjustment of the internal flux, an arc-shaped adjustment opening 75 is provided on the outer side of the arc-shaped sealing cover 72 , and an external control strip 76 protruding toward the arc-shaped adjustment opening 75 is provided on the outer arc surface of the adjustment sealing frame 73 .

[0037] When more impurities are filtered out from the surface of the metal filter 74, the internal flux will become smaller, and the smaller internal flux will cause the pressure value in the circulation process to become smaller. When the average pressure value is less than the set value, the pressure sensor module 77 will control the embedded status display light 78 to start and display a red light to remind the user to remove impurities on the surface of the metal filter 74, or to increase the flux by manually turning the external control bar 76.

[0038] In order to prevent saliva from entering the internal guide equipment tube 5, facilitate later replacement and maintain cleanliness, the internal guide assembly tube 5 is provided with a detachable sponge cover 11 at the air guide port position on the inner side of the internal breathing mask 4.
