For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] Figure 1 、 Figure 2 and Figure 3 The breathing mask with embedded adjustable filter system shown in the figure comprises an inner wearing frame 1 for wearing on the face of a user and an outer connecting cover 2 for connecting an oxygen tank, a transparent mask 3 is fixedly installed on the outer side of the inner wearing frame 1, an inner nose cover 4 is clamped and fixed on the inner side of the inner wearing frame 1, a multi-section breathing filter module 5 that can rotate is installed inside the inner wearing frame 1, and an electrically controlled flow monitoring unit 6 is installed inside the inner wearing frame 1.

[0028] In order to facilitate disassembly and assembly, an inner limiting clamping groove is formed on the outer opening position of the inner side of the inner wearing frame 1, and a lateral lock 7 that matches the inner limiting clamping groove is elastically assembled on the outer side of the outer connecting cover 2.

[0029] People control the separation of the lateral lock 7 on the outer side of the outer connecting cover 2 from the inner limiting clamping groove by pressing the lateral lock 7, so as to quickly separate the outer connecting cover 2 from the inner wearing frame 1.

[0030] In order to cooperate with the adjustment, the multi-section breathing filter module 5 comprises a cylindrical adjustment seat 51 movably installed in the inner wearing frame 1, an inner supporting frame 52 fixedly installed in the inner side of the cylindrical adjustment seat 51, a detachable closing plate 53 installed in the inner supporting frame 52, a PP cotton filter core 54 and an activated carbon filter core 55 installed in the inner side of the cylindrical adjustment seat 51, a lateral closing cover plate 56 installed on the inner side of the inner wearing frame 1, and a bottom adjustment knob 57 for controlling the cylindrical adjustment seat 51.

[0031] The inner wearing frame 1 has built-in assembly rings on both sides of the cylindrical adjusting seat 51, and then the detachable closing plate 53 is fixed inside the inner wearing frame 1 through bolts, and at the same time, the opening of the cylindrical adjusting seat 51 towards the outside is closed, so that when the external connecting cover 2 is connected, the external connecting cover 2 is connected with the external oxygen tank, and the oxygen is introduced into the built-in nose cover 4 through the multi-section breathing filter module 5; when the external connecting cover 2 is not connected, people breathe by themselves, and the external air is filtered and purified through the multi-section breathing filter module 5.

[0032] In order to match the inlet and outlet, the lateral closing cover plate 56 is provided with an external air inlet 8 with a built-in metal filter screen, and the inner wall of the cylindrical adjusting seat 51 is provided with a built-in air outlet 9 connected with the inside of the built-in nose cover 4.

[0033] Air is introduced into the cylindrical adjusting seat 51 through the external air inlet 8, and then introduced into the built-in nose cover 4 through the built-in air outlet 9.

[0034] The position of the external air inlet 8 remains fixed, and the position of the built-in air outlet 9 is adjusted along with the cylindrical adjusting seat 51. By rotating the angle of the cylindrical adjusting seat 51, the PP cotton filter core 54 or the activated carbon filter core 55 inside the cylindrical adjusting seat 51 is directed towards the external air inlet 8, so that the air entering the external air inlet 8 is filtered through the PP cotton filter core 54 or the activated carbon filter core 55 and then introduced into the built-in air outlet 9.
