[0002] During the process of fire safety and rescue, in order to avoid endangering the life and health of workers in enclosed spaces, oxygen-deficient, narrow and limited passageways, and toxic and harmful gas environments, it is necessary to wear a breathing mask to ensure the breathing safety of the wearer. Currently, breathing masks have different filtration requirements according to different usage scenarios. If the filtration requirement is lower than the scenario usage demand, the filtration effect will not meet the standard; if the filtration requirement is much higher than the scenario usage demand, it will lead to an increase in usage costs and waste of consumables. Therefore, there is an urgent need in the market for a breathing mask that can automatically adjust the type of filter material according to the usage scenario. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the breathing masks currently on the market cannot automatically adjust the consumables suitable for the filtration requirements of the scenario, resulting in a low degree of operation intelligence.

[0026] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" 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 directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] Figure 1 , Figure 2 , Figure 3 and Figure 4 A breathing mask with an electronically controlled self-regulating filtering mechanism as shown in, includes a mask body 1 and a front-mounted breathing apparatus fixed to the breathing port at the front end of the mask body 1. The front-mounted breathing apparatus includes an external housing 2 fixed to the breathing port at the front end of the mask body 1, a detachable outer separation housing 3 threadedly inserted into the outer opening of the external housing 2, a detachable multi-layer filtering module 4 installed inside the detachable outer separation housing 3, and an electronically controlled adjustment component 5 for controlling the detachable multi-layer filtering module 4.

[0029] Working principle: External air is drawn into the external housing 2 through the detachable outer separation housing 3, then undergoes adaptive filtering through the detachable multi-layer filtering module 4, and then is introduced into the mask body 1.

[0030] In order to improve the inner filtering effect, an insertable inner filtering plate 6 is installed at the inner opening position of the external housing 2.

[0031] In order to cooperate with locking, a manually controlled squeezing type lateral limiting mechanism 7 is elastically installed on the detachable outer separation housing 3.

[0032] On the threaded assembly surface of the detachable outer separation housing 3, a lateral extrusion groove for installing the manually controlled extrusion type lateral limiting mechanism 7 is provided. The manually controlled extrusion type lateral limiting mechanism 7 is installed inside the lateral extrusion groove, and the inner extrusion elastic piece is used to control the outward extrusion. The limiting block on the outside of the manually controlled extrusion type lateral limiting mechanism 7 is assembled with the side wall of the outer housing 2 in a limiting manner.

[0033] For internal assembly cooperation, the inner side surface of the detachable outer separation housing 3 has an integrally structured internal assembly rod 8. The detachable multi-layer filter module 4 includes a first separation partition plate 41, a second separation partition plate 42, a third separation partition plate 43, a first filter plate 44, and a second filter plate 45 that are slidably sleeved on the internal assembly rod 8.

[0034] For connection and filtration cooperation, internal ventilation holes 46 are provided at corresponding positions inside the first separation partition plate 41, the second separation partition plate 42, the third separation partition plate 43, the first filter plate 44, and the second filter plate 45. Particulate matter 47 for filtering air is filled at intervals inside the internal ventilation holes 44 of the first filter plate 44 and the second filter plate 45.

[0035] The particulate matter 47 can be activated carbon particles, or activated molecular sieves, or a HEPA filter.

[0036] Not all of the internal ventilation holes 44 of the first filter plate 44 and the second filter plate 45 are filled with particulate matter 47, but they are filled in an alternating manner. The effect of this is that when particulate matter filtration is not required, the internal ventilation holes 46 can be used for direct ventilation to avoid consumption of the particulate matter 47.

[0037] For lateral movable installation and limitation cooperation, the adjacent surfaces of the first separation partition plate 41, the second separation partition plate 42, and the third separation partition plate 43 have lateral limiting rings 48 for limiting the first filter plate 44 and the second filter plate 45.

[0038] The first filter plate 44 is movably inserted into the lateral limiting ring 48 between the first separation partition plate 41 and the second separation partition plate 42, and the second filter plate 45 is movably inserted into the lateral limiting ring 48 between the second separation partition plate 42 and the third separation partition plate 43.

[0039] For electric control adjustment cooperation, the electric control adjustment assembly 5 includes a first embedded adjustment motor 51, a second embedded adjustment motor 52 fixed inside the second separation partition plate 42, a first adjustment gear 53 axially fixed on the adjustment shaft of the first embedded adjustment motor 51, and a second adjustment gear 54 axially fixed on the adjustment shaft of the second embedded adjustment motor 52.

[0040] The first embedded adjustment motor 51 and the second embedded adjustment motor 52 are fixed inside the second separation partition plate 42 in a staggered manner.

[0041] In order to cooperate with the lateral gear transmission, arc-shaped adjustment tooth grooves 9 are provided on the outer arc-shaped surfaces of the first filter plate 44 and the second filter plate 45.

[0042] The first embedded adjustment motor 51 is in meshing transmission with the arc-shaped adjustment tooth groove 9 on the first filter plate 44 through the first adjustment gear 53 on the adjustment shaft, and the second embedded adjustment motor 52 is in meshing transmission with the arc-shaped adjustment tooth groove 9 on the second filter plate 45 through the second adjustment gear 54 on the adjustment shaft.

[0043] In order to perform lateral limit, lateral limit notches 10 that cooperate with the manual extrusion type lateral limit mechanism 7 are symmetrically provided at the outer opening positions of the outer housing 2.

[0044] Thread the detachable outer separation housing 3 into the inner part of the outer opening of the outer housing 2, and then after fully inserting, loosen the manual extrusion type lateral limit mechanism 7. The limit block on the outer side of the manual extrusion type lateral limit mechanism 7 is inserted into the lateral limit notch 10, so as to lock the angle of the detachable outer separation housing 3, and thus fix and limit the detachable outer separation housing 3 inside the outer housing 2.

[0045] In order to cooperate with measuring the air quality of the air inlet, an external filter monitoring port 11 is provided on the outer side of the detachable outer separation housing 3, and an embedded air quality monitoring probe 12 is fixedly installed on the inner side surface of the external filter monitoring port 11.

[0046] The embedded air quality monitoring probe 12 is a semiconductor type probe, which detects the gas concentration by using the change in the contact resistance between the gas and the semiconductor. It has the advantages of low cost, small volume, light weight, etc., and is suitable for detecting high-concentration, toxic and harmful gases. The harmful gases in the air are detected by the embedded air quality monitoring probe 12, and then the first embedded adjustment motor 51 or the second embedded adjustment motor 52 is controlled to purify the introduced air.
