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

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Figure 1 , Figure 2 and Figure 3 A breathing mask with an embedded adjustable filtering system is shown, comprising an inner wearing frame 1 for being worn on the face of a user and an external connecting cover 2 for being connected to an external oxygen tank, a transparent mask 3 is fixedly mounted on the outer side of the inner wearing frame 1, a built-in nose mask 4 is snap-fastened and fixed on the inner side of the inner wearing frame 1, a rotatable multi-stage breathing filtering module 5 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 loading and unloading, an inner limit slot is provided on the inner side surface of the inner wearing frame 1 at the outer opening position, and a lateral lock buckle 7 matching the inner limit slot is elastically assembled on the outer side surface of the external connection cover 2.

[0029] People press the lateral lock buckle 7 on the outside of the external connection cover 2 to control it to separate from the inner limiting slot, thereby quickly separating the external connection cover 2 from the inner wearing frame 1.

[0030] In order to facilitate adjustment, the multi-stage breathing filter module 5 includes a cylindrical adjustment seat 51 movably installed in the inner wearing frame 1, a built-in support frame 52 fixed inside the cylindrical adjustment seat 51, a detachable closing plate 53 installed in the built-in support frame 52, a PP cotton filter element 54 and an activated carbon filter element 55 installed inside 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] There are built-in assembly rings on both sides of the cylindrical adjustment seat 51 in the inner wearing frame 1, and then the detachable closing plate 53 is fixed to the inside of the inner wearing frame 1 by bolts, and the opening of the cylindrical adjustment seat 51 facing outward is closed at the same time, so that when the external connection cover 2 is connected externally, the external connection cover 2 will introduce oxygen into the built-in nasal mask 4 through the multi-stage breathing filter module 5 through the external oxygen tank; and when the external connection cover 2 is not connected externally, people will filter and purify the external air through the multi-stage breathing filter module 5 through spontaneous breathing.

[0032] In order to coordinate the intake and exhaust, an external air inlet 8 with a built-in metal filter is opened on the lateral closed cover 56, and a built-in exhaust port 9 connected to the inside of the built-in nose mask 4 is opened on the inner wall of the cylindrical adjustment seat 51.

[0033] The air is introduced into the cylindrical adjustment seat 51 through the external air inlet 8 , and then introduced into the built-in nasal mask 4 through the built-in air outlet 9 .

[0034] The position of the external air inlet 8 remains fixed, while the position of the internal exhaust port 9 is adjusted circumferentially along with the cylindrical adjustment seat 51. By rotating the angle of the cylindrical adjustment seat 51, the PP cotton filter element 54 or the activated carbon filter element 55 inside the cylindrical adjustment seat 51 is directed toward the external air inlet 8, so that the air entering the external air inlet 8 will be filtered by the PP cotton filter element 54 or the activated carbon filter element 55 and then introduced into the internal exhaust port 9.

[0035] In order to cooperate with the lateral engagement adjustment, an annular tooth groove 10 that engages with the bottom adjustment knob 57 is opened on the outer arc surface of the cylindrical adjustment seat 51.

[0036] In order to cooperate with the inner side assembly and fixation, a lateral assembly groove for installing the electronically controlled flow monitoring unit 6 is opened on the inner side surface of the built-in support frame 52.

[0037] In order to improve functionality and facilitate use in low-light conditions, a side-mounted lighting module 11 is movably mounted on the outer surface of the inner wearing frame 1 .

[0038] In order to cooperate with the adjustment and positioning, a built-in positioning ball 12 is elastically assembled on the inner arc surface of the inner wearing frame 1, and an external positioning blind hole 13 matching with the built-in positioning ball 12 is opened on the outer arc surface of the cylindrical adjustment seat 51.

[0039] When people use their hands to control the rotation of the bottom adjustment knob 57, the bottom adjustment knob 57 will drive the cylindrical adjustment seat 51 to rotate inside the inner wearing frame 1. Then, when the cylindrical adjustment seat 51 rotates to a specified position, the built-in positioning ball 12 will be inserted into the external positioning blind hole 13, thereby making a click sound, so that people can accurately adjust to the specified angle.

[0040] In order to display the angle of the cylindrical adjustment seat 51 and the internal flow changes in real time, an LED status display light 14 for displaying the rotation status of the cylindrical adjustment seat 51 and the operating status of the electronically controlled flow monitoring unit 6 is fixedly installed on the outer surface of the upper end of the inner wearing frame 1.

[0041] When filtering is not needed, that is, when wearing an oxygen tank for use, the LED status display light 14 is one section of green; when filtering is needed and the oxygen tank is not worn for use, the PP cotton filter element 54 is used for filtering, and the LED status display light 14 is two sections of green; when filtering is needed and the oxygen tank is not worn for use, the PP cotton filter element 54 and the activated carbon filter element 55 are used for filtering, and the LED status display light 14 is three sections of green; when the flow at the air outlet of the PP cotton filter element 54 is insufficient, the green color of the second section will turn yellow, and the color will turn red when the flow stops; when the flow at the air outlet of the activated carbon filter element 55 is insufficient, the green color of the third section will turn yellow, and the color will turn red when the flow stops.

[0042] In order to coordinate air intake and air exhaust, a first built-in check valve 15 is elastically installed inside the built-in exhaust port 9, and a second built-in check valve 16 for coordinating exhaust is installed on the outer wall of the inner wearing frame 1.

[0043] The first built-in check valve 15 can control the air in the built-in exhaust port 9 to only enter but not exit, and the second built-in check valve 16 can control the air inside the inner wearing frame 1 to only exit but not enter, so as to coordinate inhalation and exhalation.

[0044] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
