[0031] Furthermore, the locking ring 105 is a ring-shaped structure, fixedly connected to the air inlet pipe connection position on the side wall of the cover 101, and the side wall has a positioning groove; the end of the air inlet pipe 201 extends to the side wall of the locking ring, and the radial displacement of the air inlet pipe is restricted by the positioning groove to ensure that the air inlet pipe is firmly connected to the cover and to prevent loosening and leakage during airflow; the buckle 106 and the hanging ring 107 are both detachable buckle structures. The buckle 106 is fixed to the end of the ear strap 103; the hanging ring 107 is a ring-shaped protrusion fixed to the side wall of the filter 102. The two engage to achieve quick connection and disconnection of the ear strap and the filter, making it easy to wear and remove the device. For cleaning and maintenance; the exhalation valve 108 is a one-way exhaust valve, symmetrically located on the side wall of the mask 101; it only allows the exhaled airflow inside the mask to be discharged, preventing unfiltered air from entering in reverse, ensuring smooth breathing and reducing exhalation resistance, while also preventing the accumulation of exhaled moisture and heat inside the mask, thus improving wearing comfort; the cover plate 109 is a flat structure with a grille, which is snapped into the mounting groove of the filter 102 and located outside the filter element 110; the grille is used to block large particles of impurities from entering the filter and protect the filter element from contamination; at the same time, it can be quickly disassembled by the buckle 111 cooperating with the groove of the filter, making it easy to replace the filter element.

[0032] Preferably, the filter element 110 is a filter media assembly, snapped into the inside of the filter 102, located inside the cover plate 109; it is used for fine filtration of the air entering the housing, removing pollutants such as dust, droplets, and odors to ensure clean intake air; the detachable design of the cover plate facilitates regular replacement to maintain filtration effect; the buckle 111 is a symmetrically arranged protruding structure, fixed to the side wall of the cover plate 109; it fits and snaps into the groove on the side wall of the filter 102, achieving a stable connection between the cover plate and the filter, preventing the cover plate from falling off during use; at the same time, it facilitates manual removal of the cover plate, providing operation for filter element replacement. Space; the air intake pipe 201 is a hollow tubular structure, with one end extending to the side wall of the locking ring 105 of the cover 101 and communicating with the inside of the cover; it is used to deliver external air to the cover and is a supplementary channel for breathing airflow; the side wall is rotatably connected to the rotating hinge 202, providing a fulcrum for the folding of the support; the rotating hinge 202 is a rotatable connecting component, rotatably connected between the side wall of the air intake pipe 201 and the first support 203; it allows the first support to rotate around the axis of the air intake pipe and is the core structure for the device to achieve folding. By rotating the hinge, the support and headband can be stored close to the cover, reducing the size of the device.

[0033] It should be noted that both the first support 203 and the second support 204 are rigid or semi-rigid rod-shaped structures, and are rotatably connected. One end of the first support is connected to the air intake pipe via a rotating hinge 202, and the other end is connected to the second support. The end of the second support away from the first support is used to support the headband. Through the rotational cooperation of the two, the overall length of the support can be further folded and shortened to meet the needs of portable storage. At the same time, as the mounting carrier for the headband, it evenly transmits the tension of the headband to the head, enhancing the wearing stability. The first headband 205 and the second headband 206 are flexible strip-shaped structures, respectively hinged to the first support 203 and the second support 204. The support 204 has a side wall; the first headband fits the forehead or top of the head, and the second headband fits the back of the head. Together, they form a fixed structure that encircles the head, working in conjunction with the behind-the-ear straps to securely fix the device to the head and prevent the device from shifting during vigorous activity; the elastic band 207 is a highly elastic band structure, with one end fixed to the side wall of the second headband 206 and the other end connected to the side wall of the first headband 205; its elasticity allows for adjustment of the distance between the first and second headbands to accommodate different head circumferences, while providing continuous pretension to the headbands to ensure a snug and stable fit without causing excessive pressure.

[0034] When in use, the buckle 106 at the end of the ear strap 103 is engaged with the hanging ring 107 of the filter 102. The first bracket 203 and the second bracket 204 are unfolded and rotated between the hinge 202 and the bracket. The first head strap 205 and the second head strap 206 are respectively placed on the forehead and the back of the head. The elastic band 207 automatically adjusts the tightness according to the head circumference to ensure that the head strap fits the head without looseness. The flexible edge of the cover 101 is placed against the skin around the mouth and nose. The position of the ear strap is adjusted so that the cushioning pad 104 fits against the skin behind the ears. At this time, the cover and the face form a closed space. The locking ring 105 restricts the position of the air inlet tube 201 to ensure that the airflow channel is stable.

[0035] Outside air is initially filtered through the grille of the cover plate 109 and enters the filter 102. It is then finely filtered by the filter element 110 to remove pollutants such as dust and droplets. The clean air enters the mouth and nose through the hood 101 to complete inhalation. If additional air is needed, extra clean airflow can be delivered through the air inlet pipe 201. The exhaled airflow accumulates inside the hood 101, and the air pressure pushes the symmetrically arranged exhalation valves 108 to open, allowing the airflow to be discharged from the body. After exhalation, the exhalation valves automatically close to prevent unfiltered outside air from entering the hood in reverse, ensuring that the inhaled air is always filtered during breathing.

[0036] When the filtration effect of filter element 110 decreases, manually open the buckle 111 on the side wall of cover plate 109, remove the cover plate, take out the old filter element from inside filter 102, replace the new filter element, and then re-snap the cover plate back into the filter slot to complete the maintenance.

[0037] When removing the device, first unfasten the buckle 106 behind the ear straps and remove the first head strap 205 and the second head strap 206 from the head; rotate the first bracket 203 and the second bracket 204 to fold the brackets close to the air intake pipe 201, and then rotate the brackets as a whole to be close to the cover 101 by rotating the hinge 202. Finally, the size of the device is greatly reduced, making it easy to put into a backpack, pocket and other portable storage.

[0038] In summary, the rotating hinge 202 and the rotatable bracket enable the device to fold quickly, reducing its size and weight after folding, making it easy to store in a pocket or backpack. This solves the pain point of traditional head-mounted breathing devices being "large and inconvenient to carry," making it suitable for commuting, outdoor work, and other mobile scenarios. The dual filtration design of the "cover grille and filter" effectively blocks pollutants such as dust and droplets, while the one-way exhaust valve 108 prevents reverse contamination. The protection level meets the needs of daily protection and industrial dust scenarios. The detachable design of the cover 109 and filter 110 allows the filter to be replaced individually, reducing operating costs. The buckle 106 and hanging ring 107 facilitate the removal and cleaning of the ear straps. The simple structure of each component means that maintenance and operation do not require professional tools and can be completed by ordinary people.
